Description

The The invention relates to a motor strength training machine.

• 1. Die Eisenstücke 11 nehmen wegen ihrer Abmessungen einen relativ größeren Raum in Anspruch. Wenn der Widerstand beim Training eingestellt wird, muss das Gegengewicht in der Belastungsvorrichtung durch das Einsetzen bzw. Wegnehmen der Eisenstücke 11 geändert werden, was nicht nur einen großen Aufwand an Zeit und Arbeitskräften in Anspruch nimmt, sondern auch das Training unkontinuierlich macht. Eine gewünschte Trainingsauswirkung lässt sich daher schwer erzielen.
• 2. Die Eisenstücke 11 in der Belastungsvorrichtung sind nicht nur schwer, sondern auch unhandlich. Der dadurch erzeugte Widerstand lässt sich schwer einstellen, geschweige denn, einen gewünschten Widerstand beim Training nach einer vorher festgelegten Kennlinie kontinuierlich und schön glatt einzustellen. Dies beeinträchtigt die Trainingsauswirkung in einem relativ großen Maß.
• 3. Wenn die Eisenstücke 11 in der Belastungsvorrichtung durch ein Antriebsseil 12 hochgezogen bzw. aufgesetzt werden, wird ein großes Geräusch erzeugt, was nicht nur die anderen stört, sondern auch den Benutzer selbst nervös und unwohl macht.
• 4. Herkömmliche Krafttrainingsmaschine 10 gehört zu der Kategorie der Gewichtsmaschinen unterteilt, bei der der Widerstand nicht durch Vorgabe der Bewegungskurven zu verändern ist. Dabei ist ein Vibrationstraining ebenfalls nicht möglich, sodass die Bewegungsfunktionen Einschränkungen unterliegen.
• 5. Da der Widerstand während der Bewegung nicht einstellbar ist, ist eine sofortige Verringerung des Widerstands beim Überschreiten der Herzschlagfrequenz den Sicherheitsbereich der Benutzer ausgeschlossen, was eine übermäßige Bewegung bzw. eine Verletzung zur Folge hat.

Either for entertainment, health or professional reasons, fitness training is an integral part of our everyday lives. One of the strength training machines common in European and American countries, with the help of iron pieces to build muscle, to promote physical functions and to maintain physical health, so the weight training machine is also called Weight Strength Trainer. How out 1 can be seen, belongs to the conventional strength training machine 10 to the category of weight machines in which the pieces of iron 11 be used as a resistor to adjust the load. These machines are from the US 7,029,427 . US 5,833,585 such as US 4,478,411 etc. known. However, the conventional loading device of the weight machines has the following disadvantages in use:

• 1. The iron pieces 11 take a relatively larger space because of their dimensions. If the resistance is set during exercise, the counterweight in the loading device must be replaced by inserting or removing the pieces of iron 11 which not only requires a great deal of time and manpower, but also makes training discontinuous. A desired training effect can therefore be difficult to achieve.
• 2. The iron pieces 11 in the loading device are not only heavy, but also unwieldy. The resulting resistance can be difficult to set, let alone continuously and smoothly set a desired resistance during training according to a predetermined characteristic curve. This affects the training impact to a relatively large extent.
• 3. When the iron pieces 11 in the loading device by a drive cable 12 pulled up or put on, a large noise is generated, which not only disturbs the others, but also makes the user nervous and uncomfortable.
• 4. Conventional strength training machine 10 belongs to the category of weight machines, in which the resistance can not be changed by specifying the movement curves. A vibration training is also not possible, so that the movement functions are subject to restrictions.
• 5. Since the resistance is not adjustable during the movement, an immediate decrease in the resistance when the heart rate is exceeded precludes the safety margin of the user resulting in excessive movement or injury.

As above, the loading device of the conventional weight training machine 10 When using a number of disadvantages, therefore, is the conventional weight training machine 10 in need of improvement.

A The first object of the invention is a motor strength training machine to create in which the conventional iron pieces in the loading device by the torsional force of the output shaft are detached from an engine, causing a significant reduction of weight and volume and a noiseless Operation of the strength training machine allows and thus realized a light and simple structure. Furthermore is the motor strength training machine according to the invention compared to conventional weight training machine thereby excellent that a tensile, a resistance and a vibratory power using a motor to generate simultaneously. Further stand in the motor strength training machine according to the invention also several vibration waveforms available and the frequency as well as the amplitude are according to needs individually adjustable.

A second object of the invention is to provide a motor strength training machine to provide a device for improving at the Rewind occurring stress relaxation problem of the steel cord is provided. This is a coil spring for generating a certain reverse torque arranged at the end of a drive shaft of a winch, after application is fed to the drive shaft of the winch, so that the Steel rope subject to a constant tensile force. Furthermore is the drive shaft during the return due to a arranged on the front side of the drive shaft and in a pulley Roller bearing will not be able to move the heavy engine anchor into motion to set, allowing a quick and safe reversal of the steel cable through the winds is possible and therefore no Danger of failure arises.

A Third object of the invention is to provide a motor strength training machine to provide a record of the heart rate of the User is possible. When exceeding the heart rate the safety area is automatically reduced, until the heartbeat frequency to ensure health the user is in a security area.

A fourth object of the invention is to provide a motor strength training machine, in which a light barrier to the drive wave of the winch is attached. To form a motion path sensor, a pair of photocouplers operate with the light barrier. When the photocell is driven by the wind, pulse signals from the two photocouplers are sent to a forward / reverse rotation signal decoder incorporated in a controller, from which a forward / reverse rotation signal is applied to a microcomputer controlled operator console. This allows a reliable load control by a curve specification and a corresponding compensation of the load current, which offers the user a smooth and authentic situation.

In 2 and 3 a preferred embodiment of the motor strength training machine according to the invention is shown, which is a support frame 20 , a load unit 30 , a drive element 32 , a control unit 40 , a motion path sensor 38 and a coil spring 35 has, which are to be explained in more detail below.

On the support frame 20 are a seat 21 and a strength training element 22 attached, wherein the strength training element 22 with one end of a steel rope 23 communicates.

The load unit 30 is located on the support frame 20 and has an engine 31 and a drive element 32 on, in turn, with a winch 33 is coupled. Further, the winds 33 via a pulley 24 with another end of the steel cable 23 connected, with the steel cable 23 on the winds 33 umwickeln is.

The motor strength training machine according to the invention is characterized in that the engine 31 of the loading unit 30 designed as a DC motor or brushless motor and the winds 33 with a coupled drive shaft 331 through a warehouse 341 inserted through and then on a positioning bracket 34 is appropriate. In this embodiment, the positioning bracket 34 U-shaped and on a mounting plate 25 attached.

The drive element 32 includes one on an output shaft 321 of the motor ( 31 ) arranged first pulley 322 and one on the front side of the drive shaft 331 the winch 33 located second pulley 324 , one between the second pulley 324 and the drive shaft 331 inlaid unidirectional roller bearing 325 and one with the first and second pulleys 322 . 324 coupled toothed belt 323 ,

In the control unit 40 a control circuit is installed. The one from the controller 40 the engine 31 supplied power and signals are through a user-operated microcomputer-controlled control panel 50 Regulates the torsional force, the vibration frequency and amplitude of the motor 31 to control, so that a tensile, a resistance and a vibrating force at the same time of the engine 31 be generated and a vibration waveform 80 to select according to needs.

The motion path sensor 38 has one on one side of the winch 33 located and in sync with the winds 33 rotatable photocell 36 and a pair of around the perimeter of the light barrier 36 arranged photocouplers 37 , In this embodiment, the light barrier 36 on the drive shaft 331 attached while the two photocouplers 37 on the U-shaped positioning bracket 34 are attached. At the steel cable 23 transmitted rotary motion of the winch 33 the photocell turns 36 at the same time with. Thereby, pulse signals from the photocouplers 37 and then to one in the controller 40 built-in forward / reverse turn signal decoder 44 transfer. Further, those of the forward / reverse rotation signal decoder 44 emitted forward / reverse rotation signals to the realization of the load control by cornering and a suitable compensation of the load current uses the control panel 50 fed.

At the outer edge of the spiral spring 35 is a cover 39 arranged. Here is the inner end section 351 the spiral spring 35 at one on an end portion of the drive shaft 331 from the winds 33 located sleeve 342 coupled, while the outer end portion of the coil spring 35 as a hook section 352 executed and on one except the positioning bracket 34 located locking piece 391 attached. In this way, the coil spring 35 at the of the steel cable 23 transmitted rotary motion of the winch 33 so twisted that a reverse torque on the drive shaft 331 applied and then to the winds 33 is transferred, so that a constant tensile force from the steel cable 23 can be generated. That in the second pulley 324 accommodated unidirectional roller bearings 325 is during the return of the drive shaft 331 from the second pulley 324 let go, so that the motor armature is not driven, causing a rapid recoil of the steel cable 23 through the winds 33 allows. In this embodiment, the locking piece 391 on the inside of the cover 39 attached, on which the invention should not be limited.

Furthermore, there is the control circuit of the control unit 40 from a DC power supply 41 , a current and direction control unit 42 , a signal processing interface 43 and a forward / reverse rotation signal decoder 44 ,

In addition, the photocell 36 from the strength training element 22 over the winds 33 set in rotational motion, being by the two photocouplers 37 generated pulses to the forward / reverse rotation signal decoder 44 supplied forward and reverse signals and then sent to the microcomputer-controlled control panel 50 be transmitted. Therefore, it is possible, on the one hand the path of movement on the display of the microcomputer-controlled control panel 50 on the other hand, to calculate the dynamic mechanical loss of the system from the forward / reverse pulse signals to make appropriate compensation.

In addition, the above microcomputer-controlled control panel 50 , as in 2 shown to be arranged at a position to be easily adjusted on one side of the machine, wherein the control unit 40 electrically to the microcomputer-controlled control panel 50 connected. The user enters data or commands into the microcomputer-controlled operator console 50 one and the engine 31 supplied current is based on the drive signal from the controller 40 regulated.

Thereon based is the inventive motor Strength training machine distinguished by light and simple design, which is a significant reduction in weight and volume Machine allows. In addition, the inventive motor strength training machine on the one hand quiet, on the other hand, through computer regulation. After determined movement curves arises a continuously and smoothly changeable resistance force, for ease of use and significant reduction in movement injury too achieve.

Furthermore, the engine 31 and the positioning bracket 34 on the mounting plate 25 of the support frame 20 fastened, the fastening method is not previously determined.

A heartbeat rate receiver is either in the microcomputer controlled console 50 or in the controller 40 built-in to that of a heartbeat detector electrode 60 to record outputted heartbeat frequency signals of the user. The heartbeat detector electrode 60 can be embodied either as a detector electrode bound on the user's chest or as a pulse watch attached to the user's wrist, which can be made of the U.S. Patent Publications such as 4,409,983, 4,224,948 . 4,120,269 etc. and from the previous invention 5,807,267 are known, which is why details of the same are not described here.

More importantly, the engine of the invention 31 is designed as a DC motor or brushless motor. Consequently, the engine points 31 not only the above effect as tensile and resistance, but also the vibration on. After scientific researches is certain provide that an increase in muscle strength and instantaneous peak muscle strength can be realized by combining vibration stimulation with resistance training.

For this reason, the first particularity of the motor strength training machine according to the invention is the vibration training, whereby both an increase in muscle strength of athletes and a weight loss function for women and a recovery function for old people can be achieved. In the 6A and 6 a comparison is given between the conventional weight training machine and the motor strength training machine according to the invention. Compared to conventional weight machine, in which only a vibration waveform is formed, the motor strength training machine according to the invention is characterized in that the motor of the invention 31 generated vibration waveforms 80 including the sine wave 81 , the square wave 82 and the sawtooth wave 8th , etc. are changeable according to needs.

The second special feature of the motor strength training machine according to the invention is the variable tensile and resistance force. Referring to the comparative illustration in FIGS 7A and 7B are the tensile and resistance forces exerted during movement by the motorized strength training machine according to the invention in accordance with those of the microcomputer controlled control panel 50 predetermined curves 71 consistently increase or reduce. For this reason, the motor weight training machine according to the present invention is distinguished from a conventional weight machine by a significant reduction in movement injury of users, especially rehabilitation patients, old people and women.

The third peculiarity of the motor strength training machine according to the invention is that the effectiveness of the motor strength training machine according to the invention in comparison to conventional weight machine in which the effect 70 like in the 8B is shown to remain unchanged when the heart rate is exceeded over the safety margin, which places rehabilitation patients and cardiac patients at risk for regulating the heart rate of the user. When exceeding the heart rate over the safety area is the effect of the microcomputer-controlled control panel 50 automatically lower until the heartbeat rate as in 8A gradually disappears back into the security area. Optionally, the motor strength training machine according to the invention can be connected to the Internet to give the possibility that the movement behavior of the user is monitored and logged by a doctor or trainer, who can attack immediately in emergencies.

Therefore The iron pieces are unnecessary as load units in the conventional weight machine, adding the property the direct proportionality between the motor current and the torque of a motor used to adjust the load being, the realization of a synchronized vibration training is possible. In addition, the default of the Load controlled by a curve and the load current reasonably be compensated. In case of power failure, the steel cable can be avoided uncontrolled failure to be rewound, which eliminates the disadvantages of the conventional weight machine.
