Abstract
Description
- The invention relates to a rotary type adjustable cushioning mechanism of a treadmill, and more particularly, to a structure that can conduct a fine adjustment of the cushioning force of the running board when subject to a force. In this way, the operator can easily obtain the exercise comfort and the exercise effect, thereby meeting his personal use habits.
- With respect to the basic design for cushioning the running board of a conventional treadmill after being subject to a force, it is general to provide a few rubber pads at the contact surface between the periphery of the running board and the base frame. In this way, the operator will directly obtain only a fixed, soft/hard cushioning force. This simple design has advantages in the economic aspect and the convenient application. However, when we get to the bottom of its genuine benefits, it is not difficult to find that the conventional solutions are not entirely able to meet the actual needs of the users. After all, each user has significant differences in individual needs and physical conditions. As a result, the invention is intended to provide a more user-friendly and more practical cushioning design to meet the actual needs such that the user can be protected against excessive sports injuries during the exercise sessions. Moreover, it is necessary to provide a more comfortable product for the users in order to maintain or even improve the willingness in use of the products.
- A primary object of the invention is to provide a rotary type adjustable cushioning mechanism of a treadmill in which a fine adjustment of the cushioning force can be easily done. Meanwhile, the reactive force of the running board acting on the operator can be adjusted by himself at any time, thereby obtaining a proper exercise comfort and achieving an optimal exercise effect.
- According to the invention, a rotary type adjustable cushioning mechanism of a treadmill comprises a cushioning unit being interposed the base frame and the running board such that an expected and proper cushioning effect is created after the running board is subject to a force. The cushioning unit consists of two regulating mechanisms and a resilient element. Each of the regulating mechanisms includes a scale displaying disc, an adjustment knob, a transmission gear set, a position-adjusting threaded bolt, an elastic cushioning element, a coupled compression lever, and a coupled bracket pivotably attached to the running board. The resilient element is pivotably connected between both of the coupled brackets. When the adjustment knob is turned, the elastic cushioning element can move up and down on the position-adjusting threaded bolt, thereby changing the compression force between the elastic cushioning element and the coupled compression lever. As a result, the cushioning force acting on the running board can be effectively adjusted.
- The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
-
FIG. 1 is a perspective view of the cushioning mechanism assembled to a treadmill according to the invention; -
FIG. 2 is a partial side view of the invention; -
FIG. 3 is a side view of the regulating mechanism according toFIG. 2 ; -
FIG. 4 is a partial side view of the regulating mechanism according toFIG. 2 after adjustment; -
FIG. 5 is a side view of the regulating mechanism according toFIG. 4 ; and -
FIG. 6 is a perspective view of an installation example of the invention. - The present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.
- Referring to
FIGS. 1 ,2 ,3 and6 , atreadmill 10 includes abase frame 11, a runningboard 12, acontinuous moving belt 13, anelectronic console 14 with ahandrail frame 15 at both side thereof, afront roller 16, and arear roller 17, afront roller support 18, and a rear ground-touchingsupport 19. The runningboard 12 is encircled by the continuous movingbelt 13 while the continuous movingbelt 13 positioned around thefront roller 16 and therear roller 17 to conduct a in-place rotation. A cushioning unit 20 is interposed thebase frame 11 and the runningboard 12 such that an expected and proper cushioning effect is created after the runningboard 12 is subject to a force. The cushioning unit 20 consists of tworegulating mechanisms 22 and aresilient element 30. Each of theregulating mechanisms 22 includes ascale displaying disc 221, anadjustment knob 222, a transmission gear set 223, a position-adjusting threadedbolt 224, anelastic cushioning element 225, a coupledcompression lever 226, and a coupledbracket 227 pivotably attached to the runningboard 12. Theresilient element 30 is pivotably connected between both of the coupledbrackets 227. - As shown in
FIGS. 4 and5 , when theadjustment knob 222 is turned, the position-adjusting threadedbolt 224 conducts an in-place rotation through the transmission gear set 223. In this way, theelastic cushioning element 225 can move up and down on the position-adjusting threadedbolt 224, thereby changing the compression force between theelastic cushioning element 225 and the coupledcompression lever 226. As a result, the cushioning force acting on the runningboard 12 can be effectively adjusted. - The coupled
compression lever 226 is inclined in a certain manner. When theelastic cushioning element 225 is located at different height, the compression force acting on the coupledcompression lever 226 is also different before being subject to a force. In other words, theelastic cushioning element 225 is different compressed. In this way, the cushioning effect can be either soft or hard when the force acting on the above-mentioned components is changed. - When the running
board 12 is compressed, the coupledbracket 227 pivotably coupled with the runningboard 12 will sink due to the application of force. At that time, theresilient element 30 will be pulled in an extended position such that the coupledcompression lever 226 pivotably connected to the coupledbracket 227 is pushed toward theelastic cushioning element 225 to create the compression and the cushioning effect. When the external force is removed, all components subject to the force will return to their original position due to the resilience of theresilient element 30. - In order to make visible the mounting position of the related components, the
continuous moving belt 13, the runningboard 12 and thetrim strip 111 of the base frame are deliberately removed from theFIG. 1 . Likewise, therear roller 17, thetrim strip 111 and thecross strips 112 of the base frame as well as thecontinuous moving belt 13 are removed from theFIGS. 2 and4 . - As shown in
FIGS. 1 and6 , awindow cover 21 is fitted to the top of theregulating mechanisms 22 at thebase frame 11 so that the scale value on thescale displaying disc 221 is visible for the operator. - Alternatively, the
regulating mechanisms 22 of the invention can be electrically driven (not shown) so that the operator may control the cushioning force more easily. The electrically driven mechanism is a conventional and easy design so that no further descriptions thereto are given hereinafter. - In summary there is disclosed a rotary type adjustable cushioning mechanism of a
treadmill 10, comprising a cushioning unit 20 being interposed thebase frame 11 and the running board such that an expected and proper cushioning effect is created after the running board is subject to a force. The cushioning unit 20 consists of tworegulating mechanisms 22 and aresilient element 30. Each of the regulating mechanisms includes a scale displaying disc, an adjustment knob, a transmission gear set, a position-adjusting threaded bolt, an elastic cushioning element, a coupled compression lever, and a coupled bracket pivotably attached to the running board. Theresilient element 30 is pivotably connected between both of the coupled brackets. When the adjustment knob is turned, the elastic cushioning element 20 can move up and down on the position-adjusting threaded bolt, thereby changing the compression force between the elastic cushioning element and the coupled compression lever. As a result, the cushioning force acting on the running board can be effectively adjusted. - Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
