A height-adjustable device is mounted on a base portion to work with a transmission assembly of a motor and two lifting elements for adjusting the inclination of the frame portion. Meanwhile, the frame portion has a connecting rods rotatably connected by an axle of the lifting element at each of both outer sides thereof. The other end of the connecting rod is pivotably coupled with an adjustable cushioning apparatus. Thereafter, the application axle of the adjustable cushioning apparatus is pivoted at both sides of the front end of the frame portion, respectively. When weight is placed onto the frame portion, the adjustable cushioning elements are able to provide proper cushioning effect. Moreover, two adjustable cushioning elements are driven by an adjustment motor set. So the operator can preset the cushioning force via the console. A displacement detector is installed at both sides of the base portion, respectively, for detecting the displacement amount of the frame portion being forced. Thereafter, the detection data are transmitted back to the console for giving orders to the respective adjustment motor set to make corresponding reaction. Thus, the cushioning forces of the adjustable cushioning elements are constantly adjusted to the value predetermined by the operator.
Description
- 1. Field of the Invention
- The present invention relates to a new and improved design of an adjustable cushioning apparatus for a treadmill, and more particularly, to an apparatus which utilizes adjustable cushioning elements, an adjustment motor set and a displacement detector. Therefore, the operator is able to use the console to choose a desired cushioning level according to his own preference or the physician's instructions, thereby increasing the comfort in use of the treadmill.
- 2. Description of the Prior Art
- In general, the treadmill is provided with cushioning apparatuses at suitable places for achieving a proper cushioning effect and enhancing the comfort of the operator during a workout session. Meanwhile, a protection mechanism has been developed for preventing both feet of the operator from being injured due to the too large reactive force of the platform of the treadmill. It will be particularly beneficial to the operator if hydraulic or pneumatic cylinders are used to provide more excellent cushioning effect. A few prior arts such as U.S. Pat. No. 4,591,147, U.S. Pat. No. 5,184,988, U.S. Pat. No. 4,974,831, U.S. Pat. No. 4,984,810, U.S. Pat. No. 5,072,928, U.S. Pat. No. 5,372,559, etc. have disclosed the application of hydraulic or pneumatic cylinders to the treadmill.
- Although the above-mentioned prior arts have advantages of more excellent protection effect and greater comfort, they all don't have any automatic mechanism for adjusting the cushioning force by operators themselves to meet their own different requirements. In brief, a operator with heavier weight would feel that the cushioning force is too slight while a operator with lighter weight could feel that it is too strong if the cushioning force is fixed at a certain extent. Besides, different operators are their own subjective feeling about the cushioning strength no matter how strong or light the cushioning force is. In addition, some operators have special rehabilitation requirements thereto. Accordingly, the prior arts are required for improvement.
- It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide an adjustable cushioning apparatus for a treadmill that employs hydraulic or pneumatic cylinders as cushioning source. The difference between the prior art and the present invention lies in that the cushioning element of the present invention is adjustable. Meanwhile, the present invention further utilizes an adjustment motor set and a displacement detector such that the operator can use the console connected with the adjustment motor set and the displacement detector. Therefore, the desired cushioning level can be predetermined according to the preference of the user or the physician's instructions via special control keys. During the exercise session, the data regarding the exceeding or lacking amount of displacement of the frame portion measured by the displacement detectors at either side will be independently transmitted back to the console. After the processing of the microprocessor (not shown), the adjustment motor set commands the adjustable cushioning element to make proper adjustment, thereby achieving expected object.
- 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 side view of a preferred embodiment of the present invention;
- FIG. 2 is a perspective partial view of the preferred embodiment of FIG. 1; and
- FIG. 3 is a side view of FIG. 1 after adjustment of the inclination of the frame portion.
- FIG. 4 is another preferred embodiment of the present invention.
- First of all, referring to FIGS. 1 and 2, a preferred embodiment of the present invention is shown.
- The
treadmill 10 includes abase portion 20 and aframe portion 30. Ahandrail 21 is fixed at both sides of thebase portion 20 and extends upwardly therebetween. Aconsole 22 is mounted on thehandrail 21. Theframe portion 30 includes afirst motor 31 for working with adrive belt 32 and abelt wheel 33 to rotate afront roller 34. Arunning belt 36 extends around thefront roller 34 and arear roller 35 so that therunning belt 36 makes an in-place continuous rotation about theframe portion 30. A supportingboard 37 is disposed under therunning belt 36 such that the operator can stand thereon to take the walking, jogging or running exercise. Moreover, apivoting rod 23 is interposed between theframe portion 30 and thebase portion 20 for pivotably connecting to the both portions. - Referring to FIGS. 2 and 3, the
base portion 20 of thetreadmill 10 includes asecond motor 40. Atransmission assembly 41 works with twolifting elements 42 to adjust the inclination of theframe portion 30. Meanwhile, theframe portion 30 has a connectingrod 303 rotatably connected by anaxle 302 of thelifting element 42 at each of both outer sides thereof. The other end of the connectingrod 303 is pivotably coupled with anadjustable cushioning apparatus 50. Thereafter, theapplication axle 51 of the adjustable cushioning apparatus is pivoted at both sides of the front end of theframe portion 30, respectively. When weight is placed onto theframe portion 30, theadjustable cushioning elements 50 are able to provide proper cushioning effect. - Moreover, two
adjustable cushioning elements 50 are driven by anadjustment motor set 52 such that the operator can preset the cushioning force via theconsole 22. Adisplacement detector 53 is installed at both sides of thebase portion 20, respectively, for detecting the displacement amount of theframe portion 30 being forced. Thereafter, the detection data are transmitted back to theconsole 22 for giving orders to the respectiveadjustment motor set 52 to make corresponding reaction. Thus, the cushioning forces of theadjustable cushioning elements 50 are constantly adjusted to the value predetermined by the operator. - The
first motor 31, thesecond motor 40, theadjustment motor set 52 and thedisplacement detector 53 mentioned above are connected to theconsole 22 via an electronic circuit (not shown) and controlled by a microprocessor (not shown) within theconsole 22. Accordingly, the operator can determine all parameters, such as exercise duration, speed, inclination of the frame portion and the cushioning force, via the control keys (not shown) on theconsole 22. - During the exercise session, the forces applied by both feet of the operator to the
frame portion 30 could be different. Therefore, the data measured by thedisplacement detector 53 will be different as well. Thedisplacement detectors 53 of theadjustable cushioning elements 50 independently send the respective detection signal back to theconsole 22. According to the real data measured by thedisplacement detectors 53 together with the preset value of the operator, theadjustment motor sets 52 are independently controlled to make a timely reaction. Therefore, theadjustable cushioning elements 50 can be duly adjusted to provide the same cushioning forces for meeting different requirement of operators. - In fact, the adjustment motor set52 further includes a motor and a gearbox. Due to the rotation of the output shaft of the motor and the deceleration by the gearbox, the adjusting knob can be conveniently used for a smooth adjustment. This is a common technique so that no further descriptions thereto are given hereinafter.
- Of course, as illustrated in FIG. 4, the front end of the frame portion can be provided with a pivoting
piece 38 for facilitating the movement of theadjustable cushioning apparatus 50. Meanwhile, theapplication axle 51 of theadjustable cushioning apparatus 50 is mounted on the pivotingpiece 38. - Many changes and modifications in the above-described embodiment 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.
