FIG. 1 is a perspective view illustrating a training device according to a first example embodiment of the present invention.
In FIG. 1 , the training device 100 of the present embodiment is used
395 for rehabilitation or exercise, and includes a rotating member 102, a controller 104, a handling member 106 and a user identification member 116.
The rotating member 102 as rotatable element is for example high- powered electric motor.
This rotating member 102 performs an isotonic exercise, an
400 isokinetic exercise, an isometric exercise, a maximum muscular strength measuring exercise, an ROM exercise or a program exercise as described below.
In one example embodiment of the present invention, the rotating member 102 is a synchronous motor for generating a rotatory power through 405 a method of synchronizing an input frequency with a rotation frequency, and uses a permanent magnetic as described below.
In the synchronous motor unlike an induction motor having slip, rotation velocity is not changed though load of the synchronous motor is increased or reduced. This is, slip is not generated to the synchronous 410 motor.
The controller 104 controls rotation of the rotating member 102, measures momentum and muscular strength when a user trains, and may transmit the measured result to an outside communication device.
In addition, the controller 104 may control driving of the training 415 member 102 in accordance with control of the communication device. Here, location of the controller 104 is not limited as that in FIG. 1 , and may be variously modified.
In one example embodiment of the present invention, the controller 104 applies three-phase synchronous torque current to the rotating member
420 102, thereby controlling torque of the rotating member 102. The handling member 106 displays modes to be selected by the user, and provides information concerning the mode selected by the user to the controller 104.
Additionally, the handing member 106 displays momentum and
425 muscular strength, etc measured by the controller 104. On the other hand, the handing member 106 may display also various items such as torque, rotation velocity, repetition number, set number, etc in accordance with objection of the user. In other words, the handing memberlO6 may display various modes and measured parameters in accordance with setting of the
430 user.
This handling member 106 may be controlled by an outside means such as a remote control, key button, etc, and operate with a touch screen method.
In one example embodiment of the present invention, the handling 435 member 106 may have separately a part on which the modes selected by the user are displayed and a part on which the measured result is displayed.
The user identification member 116 identifies the user, and identifies generally the user through a personal card of the user or extra identification device. In another example embodiment of the present invention, the
440 training device 100 may identify the user by using a method of inputting identification number through the handling member 106.
Hereinafter, an up-training process and a down-training process in the training device 100 will be described in detail.
Firstly, the up-training process will be described.
445 The user sits on a seat 108, and then grasps a training grip 112 with two hands under the condition that the user's arm is laid on an arm supporting member 110.
Subsequently, the user rises the training grip 112 in a direction opposed to a gravitational direction, and thus the user's power is delivered to 450 the rotating member 102 through a frame 114. In this case, the controller 104 drives the rotating member 102 in accordance with the isotonic exercise or the isokinetic exercise, etc., and so the rotatory power and rotation velocity of the rotating member 102 is changed depending on the user's power. Here, the isotonic exercise means exercise through constant 455 rotatory power during the user's training, and the isokinetic exercise indicates exercise through constant rotation velocity during the user's training. This will be described in detail with reference to accompanying drawings.
Then, the controller 104 detects torque, e.g. rotatory power or rotation
460 velocity in accordance with driving of the rotating member 102 through following sensing member, and measures the user's momentum, i.e. muscular strength through the detection result. In one example embodiment of the present invention, the controller 104 may measure also maximum muscular strength in the up-training process. 465 Hereinafter, the down-training process will be described.
The controller 104 rotates the rotating member 102 in the gravitational direction in accordance with the isotonic exercise or the isokinetic exercise, etc.
Subsequently, the user grasps the training grip 112, and then comes
470 down the training grip 112 with holding the arm in the direction opposed to the gravitational direction. In this case, the rotatory power or the rotation velocity of the rotating member 102 is changed depending on the exercising type of the rotating member 102, e.g. isotonic exercise or isokinetic exercise.
The controller 104 detects the changed rotatory power or rotation
475 velocity, and measures the user's momentum and maximum muscular strength in the down-training process.
That is, the controller 104 measures the user's muscular strength through the above method. Then, the training device 100 may provide a training program suitable for the user's muscular strength to the user through
480 the handling member 106. Hence, the user may train in accordance with the provided training program. In this case, since the user trains in accordance with his maximum muscular strength, the user may train efficiently without damaging to his muscle.
In brief, the training device 100 adjusts exercising load, i.e. weight by
485 using the rotating member 102 controlled accurately unlike the training device in related art using the weight body having specific weight. Accordingly, the training device 100 of the present embodiment may control accurately the exercising load and provide training suitable for the user's maximum muscular strength to the user unlike the training device in related
490 art.
The training device 100 for the upper half of the user's body is mentioned in above description. However, a training device for the lower half of his body is also included in the training device 100 of the present invention. In addition, the training device 100 of the present invention may
495 be employed as a medical instrument and a rehabilitation device.
FIG. 2 is a view illustrating schematically a training device according to a second example embodiment of the present invention. FIG. 3 is a view illustrating schematically an exercising load control member according to a first example embodiment of the present invention.
500 Referring to FIG. 2, the training device 200 of the present embodiment controls electrically the exercising load, i.e. weight, and includes a body member 202 and an exercising load control member 204.
The body member 202 means the other part except the exercising load control member 204, and has a frame 210 and a connection member 218
505 such as a belt or a wire, etc.
The exercising load control member 204 is connected to the body member 202, and controls the exercising load during the user's training. This exercising load control member 204 includes a rotating member 212, a power delivering member 216 and a controller 214.
510 The power delivering member 216 delivers a rotatory power in accordance with rotation of the rotating member 212 to the body member 202 through the connection member 218, or delivers a power provided from the body member 202 to the rotating member 212 when the user trains.
In one example embodiment of the present invention, the power
515 delivering member 216 is a pulley connected to an end of an axis member of the rotating member 212, and rotates in response to the rotation of the rotating member 212. Here, the connection member 218 connects the power delivering member 216 to the body member 202 as shown in FIG. 2. However, location and structure of the connection member 218 may be
520 variously modified in accordance with kind of the training device 200. The controller 214 controls rotation of the rotating member 212, and rotates the rotating member 212 by applying for example specific current to the rotating member 212 in accordance with a mode selected by the user. In this case, a sensing member 300 in FIG. 3 senses torque of the rotating
525 member 212 through the applied current.
However, an above method of measuring the torque of the rotating member 212 through the sensing member 300 does not sense directly the rotation of the rotating member 212, and so torque sensing ability may be lowered.
530 Accordingly, the present invention provides further a following method for the purpose of enhancing the torque sensing ability.
FIG. 4 is a view illustrating schematically an exercising load control member according to a second example embodiment of the present invention. FIG. 5 is a view illustrating schematically an exercising load control member
535 according to a third example embodiment of the present invention.
A sensing member 300 in the second embodiment, e.g. a torque sensor is formed to an axis member 212B of the rotating member 212 as shown in FIG. 4. In other words, the torque sensor 300 senses directly rotation velocity of the axis member 212B when the axis member 212B is rotated,
540 and so the torque of the rotating member 212 may be accurately sensed. A sensing member 500 in the third embodiment, e.g. load cell is formed to the connection member 21 8 as shown in FIG. 5. That is, the load cell 500 is connected to the connection member 218, e.g. both ends of a belt, and senses the torque of the rotating member 212 through change of the belt 545 218. Here, since the connection member 218 is changed in proportion to the rotation velocity of the rotating member 212, the load cell 500 may sense accurately the torque of the rotating member 212.
FIG. 6 is a perspective view illustrating a training device according to a third example embodiment of the present invention.
550 In FIG. 6, the training device 600 of the present embodiment includes a rotating member 602, a controller 604, a handling member 606, a gear 608, a weight body 610, a wire 612, a user identification member 618 and a body member. Here, the body member means the other part the training device 600 except the rotating member 602, the controller 604, the handling 555 member 606, the gear 608, the weight body 610, the wire 612 and the user identification member 618, and includes a training grip 614 and a frame 616. The gear 608 is connected to the rotating member 602, and rotates in response to rotation of the rotating member 602.
The weight body 610 is connected to the rotating member 602 through
560 the gear 608 and the wire 612, and has a given weight. As a result, the weight body 610 determines initial weight when the rotating member 602 is operated.
The wire 612 is connected to the body member and the gear 608, and delivers a rotatory power in accordance with rotation of the gear 608 to the 565 weight body 610 and the frame 616 in the body member.
That is, the training device 600 of the present embodiment uses the weight body 610 as well as the rotating member 602 so as to control the exercising load unlike the first embodiment and the second embodiment. Accordingly, though the rotating member 602 having low output efficiency is 570 used in the training device 600, the training device 600 of the present embodiment may have the same efficiency as those in the first embodiment and the second embodiment.
In addition, since the exercising load is accurately controlled by using the rotating member 602 though the weight body 610 is used, the user may 575 exercise efficiently without damaging to his body.
As shown in the first embodiment to the third embodiment, the training device of the present invention may be variously modified as long as the exercising load is controlled by using the rotating member.
FIG. 7 to FIG. 10 are perspective views illustrating training devices
580 according to a fourth example embodiment of the present invention. In FIG. 7, the training device 700 of the present embodiment includes a rotating member 702, a controller 704, a power delivering member, a wire 712 and a handling member 716.
The power delivering member has a gear 706, a belt 708 and a moving 585 member 710.
Since the other elements of the present embodiment except the power delivering member are similar to those in the third embodiment, any further description concerning similar elements will be omitted.
The gear 706 includes an upper gear and a lower gear as shown in FIG. 590 7. Here, the upper gear or the lower gear is connected to the rotating member 702. As a result, the gear 706 rotates in response to rotation of the rotating member 702.
The belt 708 is connected to the gear 706, and moves ups and downs in response to rotation of the gear 706.
595 The moving member 710 is combined with the belt 708 and the wire
712, and moves ups or downs in accordance with operation of the belt 708, thereby delivering the power in accordance with the rotation of the rotating member 702 to a frame through the wire 712.
In other words, the moving member 710 delivers the power in
600 accordance with the rotation of the rotating member 702 to the frame, and indicates a direction in which the user trains using the training device 700.
In the above description, the training device 700 uses the weight body 714. However, the training device 700 may not use the weight body 714.
Hereinafter, a training device 800 unlike that in FIG. 7 will be 605 described in detail with reference to accompanying drawing FIG. 8. Here, the other elements except the same elements as in FIG. 7 will be described.
As shown in FIG. 8, a screw 804 is connected to a rotating member 802, and is inserted into a nut 806. Hence, the screw 804 moves in an up direction or in an down direction on the basis of the nut 806 in accordance 610 with rotation of the rotating member 802. In other words, the nut 806 delivers a power in accordance with the rotation of the rotating member 802 to a frame through a wire, and indicates a direction in which the user exercises using the training device 800.
In FIG. 8, the screw 804 indicates the direction in accordance with the
615 rotation of the rotating member 802. In another example embodiment of the present invention, the training device 800 may move a nut in response to rotation of a rotating member under the condition that a screw is fixed, which is not shown.
In short, unlike the first embodiment to the third embodiment, the
620 training devices 700 and 800 of the fourth embodiment includes further the power delivering member for delivering the rotatory power of the rotating member 702 and 802 to the body member.
Training devices in FIG. 9 and FIG. 10 may be employed as example of the fourth embodiment. Here, since the training devices are similar to
625 the training devices 700 and 800, any further description concerning the training devices will be omitted. That is, the power delivering member may be variously modified. Accordingly, it will be immediately obvious to those skilled in the art that many modifications for the training device do not have any effect to the scope of the present invention.
630 FIG. 11 is a block diagram illustrating a training system having a training device according to one example embodiment of the present invention. FIG. 12 is a sectional view illustrating a rotating member according to one example embodiment of the present invention. Here, the training device 100 in the first embodiment will be used as example of the
635 training device. In addition, the rotating member 102 is assumed as an electric motor.
In FIG. 11 , the training system of the present embodiment includes the training device 100, a communication device 1106 and a network 1 108.
The training device 100 has a body member 1 100, the rotating
640 member 102, a sensing member 1 102, a reducer 1 104, the controller 104, the handling member 106 and the user identification member 116.
Hereinafter, operation of the training device 100 will be firstly described, and then the training system will be described.
The body member 1100 indicates the other members of the training 645 device 100 except the rotating member 102, the sensing member 1102, the reducer 1104, the controller 104, the handling member 106 and the user identification member 116.
The rotating member 102 is made up of a stator 1200 and a rotor 1202.
Wires are wound with specific pattern, e.g. aa', bb' and cc' on the 650 stator 1200, and a permanent magnetic 1204 is adhered to an outer side of the rotor 1202.
To generate maximum torque using the rotating member 102, three- phase synchronous torque current U, V and W, having phase vertical to location of the rotor 1202, are applied to the wires of the stator 1200 as 655 shown in FIG. 12(A) and FIG. 12(B). As a result, rotating (magnetic) field is formed as shown in FIG. 12(A), and so the permanent magnetic 1204 is rotated. Accordingly, the rotor 1202 rotates with the same rotating velocity as the permanent magnetic 1204.
Since the rotating member 102 operates as mentioned above, the
660 training device 100 of the present embodiment may detect the location of the rotor 1202 by using the sensing member 1102, and apply the three-phase synchronous torque current U, V and W having phase vertical to the detected location to the stator 1200 to the stator 1200, thereby generating constant torque.
665 Unlike an induction rotating member having slip, i.e. velocity difference of a rotor and a stator, rotating torque of the rotating member 102 is proportion to the three-phase synchronous torque current U, V and W because magnetic field of the stator 1200 and the rotor 1202 maintains a phase difference by 90° . In other words, slip is not generated in the
670 rotating member 102. As a result, the rotating torque of the rotating member 102 may be accurately controlled by adjusting the three-phase synchronous torque current U, V and W.
Structure of the rotating member 102 is not limited as in FIG. 12, and may be variously modified.
675 Now referring to FIG. 11 , the controller 104 controls the rotating member 102 so that the rotating member 102 operates in accordance with a given mode. Specially, the controller 104 controls the torque of the rotating member 102.
The reducer 1 104 reduces rotation number of the rotating member 102,
680 particularly a rotating axis, thereby increasing the torque of the rotating member 102. However, the reducer 1104 is not necessarily included in the training device 100.
The sensing member 1102 senses torque of the rotating member 102, for example senses location, angle or velocity of the rotor in the rotating 685 member 102. Accordingly, the sensing member 1 102 may have a location sensor 1 1 10 and an angle sensor 1112.
Additionally, the sensing member 1102 transmits the sensed result to the controller 104.
The controller 104 analyzes the sensed result transmitted from the 690 sensing member 1 102, and controls the rotating member 102 in accordance with the analysis so that the rotating member 102 operates in accordance with the given mode.
That is, the training device 100 of the present embodiment drives the rotating member 102 by providing the three-phase synchronous torque
695 current to the rotating member 102, senses the torque of the rotating member
102 through the sensing member 1 102, and controls the rotating member 102 in accordance with the sensed result.
Hereinafter, the training system of the present embodiment will be described in detail.
700 The training device 100 measures the user's training result when the user trains, and transmits the measured result to the communication device 1106 through the network 1108. Here, the communication device 1106 is not limited as specific terminal as long as the communication device 1106 is coupled to the training device 100. In other words, the communication 705 device 1106 includes a server, a mobile terminal, a computer, etc.
The communication device 1 106 may store the measured result, analyze the measured result, and note the analyzed result to the user.
In another example embodiment of the present invention, the communication device 1106 may drive the training device 100 with a preset 710 mode by transmitting specific message having a driving command to the controller 104.
FIG. 11 shows one training device 100. However, users may train using a plurality of training devices as described below. In this case, the communication device 1106 may train together the users by driving the
715 training devices with given pattern. This will be described in detail with reference to accompanying drawing.
FIG. 13 is a block diagram illustrating a controller according to one example embodiment of the present invention. Here, the controller is assumed as the controller 104 in FIG. 1.
720 In FIG. 13, the controller 104 includes a controlling section 1300, a mode section 1302, an analysis section 1304, a torque section 1306, a measuring section 1308, a storage section 1310 and a communication interface 1312.
The mode section 1302 controls operation related to a training mode, 725 and provides modes to the user through the handling member 106.
The analysis section 1304 analyzes the sensed result transmitted from the sensing member 1102, and provides the analyzed result to the torque section 1306.
The torque section 1306 controls the torque of the rotating member
730 102 so that the rotating member 102 operates with a mode selected by the user. For example, the torque section 1306 controls the torque of the rotating member 102 by applying the three-phase synchronous torque current to the rotating member 102.
In addition, the torque section 1306 adjusts magnitude of the current 735 applied to the rotating member 102 so that the rotating member 102 operates with the selected mode in accordance with the analyzed result provided from the analysis section 1304.
The measuring section 1308 measures the torque, rotatory power or rotation velocity of the rotating member 102 when the rotating member 102
740 rotates in accordance with the selected mode, and then detects momentum and maximum muscular strength of the user, etc through the measured result.
The storage section 1310 may store maximum muscular strength for each users and daily record concerning the momentum, etc.
The communication interface 1312 is connection path between the 745 training device 100 and the communication device 1106, and provides a wire communication or wireless communication.
The controlling section 1300 controls operation of the elements in the controller 104.
Hereinafter, a method of driving the training device 100, 200, 400,
750 600, 700, 800, 900 and 1000 will be described in detail with reference to accompanying drawings. Here, numerical number for the training device
100, 200, 400, 600, 700, 800, 900 and 1000 will be omitted for convenience of description.
FIG. 14 is a view illustrating a training mode in the training device 755 according to one example embodiment of the present invention.
As shown in FIG. 14, the training device of the present invention provides an isotonic mode 1400, an isokinetic mode 1402, a maximum muscular strength measuring mode 1404, an isometric mode 1406, an ROM mode 1408 and a program mode 1410 to the user through the handling
760 member 106. Here, operation of the training device in accordance with the modes 1400, 1402, 1404, 1406, 1408 and 1410 will be described in detail.
Firstly, operation of the training device in accordance with the isotonic mode 1400 will be described.
765 FIG. 15 is a flowchart illustrating a process of operating the training device in accordance with the isotonic mode according to one example embodiment of the present invention. FIG. 16 is a view illustrating change of exercising load in accordance with the isotonic mode according to one example embodiment of the present invention.
770 In FIG. 15, in step S 1500, the user selects the isotonic mode 1400 of the training mode.
In step S 1502, the rotating member rotates in a gravitational direction in accordance with the selected mode.
In step S 1504, the user starts up-training, and then it is discriminated 775 whether or not the user's power, delivered to the rotating member from the body member, is more than a rotatory power of the rotating member.
In case that the user's power is smaller than the rotatory power, i.e. in case that the power by the user can not change rotation direction of the rotating member, the step S 1502 is again performed.
780 However, in case that the user's power is more than the rotatory power, i.e. in case that the power by the user can change the rotation direction of the rotating member, the rotating member rotates in a direction opposed to the gravitational direction in accordance with the up-training in step S 1506. Here, the rotatory power is constantly maintained during the up-training, i.e.
785 while moving angle of the frame is increased as shown in FIG. 16(A), and thus rotation velocity of the rotating member is changed in accordance with the user's power. In this case, only specific muscle is trained. However, in case that the user wants to train another muscle, exercising load may be increased or reduced according as the moving angle is augmented as shown
790 in FIG. 16(B). That is, in the isotonic mode 1400, the training device controls the exercising load in accordance with kind of the muscle to be trained.
In step S 1508, the measuring section detects the user's momentum through the changed rotation velocity in the up-training. For example, the
795 controller controls driving of the rotating device by using the current, the measuring section may detect the user's momentum in the up-training by measuring and analyzing current corresponding to the changed rotation velocity. On the other hand, the controller may control the rotating member by using other factor such as a voltage, etc not the current, and the
800 measuring section may detect the user's momentum through the factor. In step S 1510, it is discriminated whether or not location of the frame is more than an up angle. In other words, it is discriminated whether or not the frame is risen up to increase limit of the training device.
In case that the location of the frame is smaller than the up angle, the 805 step S 1508 is again performed.
However, in case that the location of the frame is more than the up angle, the torque of the rotating member is changed in the gravitational direction in accordance with the down-training, i.e. the rotating member rotates in the gravitational direction in step S 1512.
810 Subsequently, the user starts the down-training with holding the arm in the direction opposed to the gravitational direction. Here, since the rotating member rotates in the gravitational direction with constant rotatory power, the rotation velocity of the rotating member is changed in accordance with the user's power, and the measuring section measures the changed 815 rotation velocity in step S 1514.
In step S 1516, the measuring section analyzes the measured rotation velocity, thereby detecting the user's momentum in the down-training.
In brief, the training device of the present embodiment detects respectively the momentum in the up-training and the momentum in the
820 down-training in accordance with the isotonic mode 1400, and displays the detected momentum through the handling member for the user to see the detected momentum.
In another example embodiment of the present invention, driving of the training device may be terminated in accordance with training number 825 and training time, which is not described above. That is, the user sets the training number and the training time not to damage to the user's body due to over-training, and stops the driving of the training device in case that the training number or the training time is more than a preset number or time. In this case, the frame is changed into an initial condition.
830 Hereinafter, operation of the training device in accordance with the isokinetic mode 1402 will be described in detail.
FIG. 17 is a flowchart illustrating a process of operating the training device in accordance with the isokinetic mode according to one example embodiment of the present invention.
835 In FIG. 17, in step S 1700, the user selects the isokinetic mode 1402 of the training mode.
In step S 1702, the rotating member rotates in the gravitational direction in accordance with the selected mode.
In step S 1704, the user starts an up-training, and then it is
840 discriminated whether or not the user's power, delivered to the rotating member from the body member, is more than a rotatory power of the rotating member.
In case that the user's power is smaller than the rotatory power, the step S 1702 is again performed. 845 However, in case that the user's power is more than the rotatory power, the rotating member rotates in a direction opposed to the gravitational direction in accordance with the up-training in step S 1706. Here, the rotation velocity of the rotating member is constantly maintained during the up-training. In case of increasing the rotation velocity by the user's power, 850 a power in the gravitational direction is provided to the rotating member.
As a result, the rotatory power of the rotating member is changed in accordance with the user's power.
In step S 1708, the measuring section detects the user's momentum through the changed rotatory power in the up-training. 855 In step S 1710, it is discriminated whether or not location of the frame is more than an up angle. In other words, it is discriminated whether or not the frame is risen up to increase limit of the training device.
In case that the location of the frame is smaller than the up angle, the step S 1708 is again performed.
860 However, in case that the location of the frame is more than the up angle, the torque of the rotating member is changed in the gravitational direction in accordance with a down-training, i.e. the rotating member rotates in the gravitational direction in step S 1712.
Subsequently, the user starts the down-training with holding the arm 865 in the direction opposed to the gravitational direction. Here, since the rotating member rotates in the gravitational direction with constant rotation velocity, the rotatory power of the rotating member is changed in accordance with the user's power, and the measuring section measures the changed rotatory power in step S 1714. 870 In step S 1716, the measuring section analyzes the measured rotatory power, thereby detecting the user's momentum in the down-training.
In short, the training device of the present embodiment detects respectively the momentum in the up-training and the momentum in the down-training in accordance with the isokinetic mode 1402, and displays the 875 detected momentum through the handling member for the user to see the detected momentum.
Hereinafter, operation of the training device in accordance with the maximum muscular strength measuring mode 1404 will be described in detail.
880 FIG. 18 is a flowchart illustrating a process of operating the training device in accordance with the maximum muscular strength measuring mode according to one example embodiment of the present invention.
In FIG. 18, in step S 1800, the user selects the maximum muscular strength measuring mode 1404 of the training mode.
885 In step S 1802, the rotating member rotates in a direction opposed to the gravitational direction in accordance with the selection. Accordingly, the frame moves in the direction opposed to the gravitational direction though the user does not provide a certain power to the training device.
Subsequently, the user starts up-training with his maximum muscular
890 strength. In this case, the rotating member rotates with constant rotation velocity during the up-training. In other words, in case of increasing the rotation velocity by the user's power, a power in the gravitational direction is provided to the rotating member. Hence, the rotatory power of the rotating member is changed in accordance with the user's power.
895 In step S 1804, the measuring section measures the changed rotatory power, and detects the maximum muscular strength of the user in the up- training through the measured result.
In step S 1806, it is discriminated whether or not location of the frame is more than an up angle. In other words, it is discriminated whether or not
900 the frame is risen up to increase limit of the training device. In case that the location of the frame is smaller than the up angle, the step S 1804 is again performed.
However, in case that the location of the frame is more than the up angle, the controller changes the torque of the rotating member in the 905 gravitational direction in accordance with the down-trining, i.e. the rotating member rotates in the gravitational direction in step S 1808.
Subsequently, the user starts the down-training with holding the arm with maximum muscular strength in the direction opposed to the gravitational direction. Here, since the rotating member rotates in the 910 gravitational direction with constant rotation velocity, the rotatory power of the rotating member is changed in accordance with the user's power, and the measuring section measures the changed rotatory power in step S l 810.
In step S 1812, the measuring section analyzes the measured rotatory power, thereby detecting the maximum muscular strength of the user in the 915 down-training.
In brief, the training device of the present embodiment detects respectively the maximum muscular strength in the up-training and the maximum muscular strength in the down-training in accordance with the maximum muscular strength measuring mode 1402, and displays the detected
920 maximum muscular strength through the handling member for the user to see the detected momentum.
Hereinafter, a process of detecting the maximum muscular strength of the user and then setting a training program in accordance with the detected maximum muscular strength will be described with reference to below Tables. Here, the isotonic mode is assumed as mode 0, and the isokinetic mode is referred to as mode 1.
[ TABLE 1 ]
Figure imgf000049_0001
[ TABLE 2]
Figure imgf000050_0001
As shown in Table 1 and Table 2, the training device of the present invention measures maximum muscular strength of each users, and sets a training program for the up-training and a training program for the down- training in accordance with the measured maximum muscular strength.
Accordingly, the user may train without damaging to his body.
In addition, the training device may set differently a training program for man who wants to increase muscle, a training program for woman to who repetitive training is required, and an old person to who over-training is prohibited. Hence, the user may perform proper exercise in accordance with his sex distinction and age.
Furthermore, the user may train with changing modes. Therefore, training efficiency of the user may be enhanced because the user trains in accordance with his condition.
945 Now referring to Table 1 and Table 2, the training device of the present invention may set differently the UP power in the up-training and the DOWN power in the down-training.
In the down-training, muscle of human has generally a power higher than in the up-training. Accordingly, the training device may set the power
950 so that the DOWN power is higher than the UP power, and so the user may train more efficiently though the user trains with exercising load corresponding to the weight body in related art.
Hereinafter, operation of the training device in accordance with the isometric mode 1406 of the training mode will be described in detail. 955 FIG. 19 is a flowchart illustrating a process of operating the training device in accordance with the isometric mode according to one example embodiment of the present invention.
In FIG. 19, the isometric mode 1406 of the training mode is selected in step S 1900.
960 In step S 1902, in case that the user provides a certain power to the frame of the training device, the frame moves automatically up to a preset angle, and then the frame is fixed. That is, in the isometric mode 1406, the user trains a specific muscle under the condition that the frame is fixed. Here, the preset angle may be freely set in accordance with body 965 characteristics or muscle of the user.
In step S 1904, the user exercises using the fixed frame.
In step S 1906, it is discriminated whether or not training time performed by the user is higher than a predetermined time. Here, the user's body is not damaged in case that the user trains in the range of the 970 predetermined time.
In case that the training time is less than the predetermined time, the training device maintains the frame to fixed state because the training is not damaged to the user's body.
However, in step S 1908, in case that the training time is higher than 975 the predetermined time, the training device stops the training because the training can damage to the user's body. For example, the training device changes location of the frame into initial location, i.e. 0° angle in case that the training time is higher than the predetermined time. In other words, since training number is meaningless in the isometric exercising, the training
980 device controls the user's training through only the training time. In step S 1910, the training device analyzes user's momentum, and detects the user's maximum muscular strength and muscular endurance, etc through the analyzed result. In addition, the training device provides the detected result to the user through the handling member.
985 Hereinafter, operation of the training device in accordance with the
ROM mode 1408 of the training mode will be described in detail.
FIG. 20 is a flowchart illustrating a process of operating the training device in accordance with the ROM mode according to one example embodiment of the present invention.
990 In FIG. 20, in step S2000, the ROM mode 1408 of the training mode is selected. Here, the ROM mode is mainly used for rehabilitation, and controls to move automatically the frame in a given range though the user does not provide a power to the frame.
In step S2002, the range, i.e. angle range of the frame is set in 995 accordance with condition of the user. For example, a rehabilitation training manager may set the angle range in accordance with the condition of the user.
In step S2004, the frame moves automatically in the set angle range, thereby making the user exercise.
1000 In step S2006, it is discriminated whether or not the user provides a power opposed to the training direction to the frame. For example, it is discriminated whether or not the user provides a power in the gravitational direction due to physical pain while the user rises the frame for leg training up to specific angle.
1005 In case that the user does not provide the power opposed to the training direction to the frame, the step S2004 is continuously performed.
However, in step S2008, in case that that the user provides the power opposed to the training direction to the frame, the training device moves the frame in a direction (second direction) opposed to the present training
1010 direction (first direction) not to damage the user's body. In other words, rotation direction of the rotating member is changed in the second direction.
In step S2010, the frame moves up to the preset angle in the second direction, and then moves in the first direction. Here, the frame may move in the preset angle range irrespective of angle corresponding to the power
1015 provided in the second direction. In another example embodiment of the present invention, the preset angle range may be newly set to angle range corresponding to the power provided in the second direction, and the frame may move in the angle range set newly.
As described above, the ROM mode 1408 may train efficiently
1020 without damaging to the user's body. Specially, since the training device of the present invention uses the rotating member operated electrically, the exercising load and the angle may be accurately controlled. Accordingly, the training device may provide optimal rehabilitation exercising to a patient. In one example embodiment of the present invention, operation of the
1025 training device may be terminated in case that the training number or the training time is higher than the preset number or the predetermined time, i.e. the frame is changed into initial state. Then, the training device analyzes the training, and provides momentum corresponding to the analyzed result to the user through the handling member.
1030 Hereinafter, operation of the training device in accordance with the program mode 1410 will be described in detail.
The program mode 1410 means a combination exercising of the isotonic exercising, the isokinetic exercising and the isometric exercising. For example, the training device provides the isotonic exercising while the
1035 frame is risen, and provides the isokinetic exercising while the frame is downed. For another example, the training device provides the isotonic exercising while the frame is increased, the frame is fixed after the frame is risen up to the up angle, and then the training device provides the isometric exercising. For still another example, the training device may set
1040 differently a power in the up-training and a power in the down-training though the same mode is used in the up-training and the down-training.
In one example embodiment of the present invention, the training device may be connected to a computer (not shown). In case that it is difficult to handle finely program of the training device because screen of
1045 the handling member is small, the user may handle finely the program of the training device through display section of the computer.
FIG. 21 is a flowchart illustrating a process of operating training devices according to one example embodiment of the present invention. Here, it is assumed that one communication device is connected to a 1050 plurality of training devices through wireless communication.
In FIG. 21 , in step S2100, a trainer in a sports center sets training program for the training devices to the communication device so as to train together users.
In step S2102, the communication device transmits the set training 1055 program to the training devices through a network. Here, the training programs have the same pattern, or have different pattern. It is desirable that the training programs have different pattern depending on the users.
In step S2104, the training devices operate in accordance with the transmitted training program. In this case, the training devices may be
1060 driven simultaneously, or be driven respectively. In other words, the users train together through the above method, and so the users are excited about the training instead of boring due to exercising alone. For example, running machines for users are disposed so that the users see one another, and then the running machines are driven. Hence, the users have a face to 1065 face talk and exercising, and so the users may be interested in training. In addition, the users may socialize.
In step S2106, it is discriminated whether or not new training is started.
In case that the present training is not finished, the step S2104 is 1070 again performed.
However, in case that the present training is finished and then new training is being started, the trainer sets new training program to the communication device in step S2108. In one example embodiment of the present invention, the new training program is not set whenever the new 1075 training is being started, but every training program may be preset at one time before the training is started.
In step S2110, the communication device transmits the set training program to the training devices, and the training devices drive in accordance with the transmitted training program.
1080 In brief, the training system of the present embodiment transmits the training program to plural training devices to train together the users.
