Abstract
A cushioning mechanism for a treadmill, wherein at least one set of the cushioning mechanism is interposed between a base frame and a running board, and wherein the cushioning mechanism includes two support hanging pieces, two swing hanging pieces, and an arched metal plate, and wherein the top surface of the arched metal plate is just in contact with the bottom surface of the running board. When the running board is subject to a downward force and sink, the arched metal plate mounted below will be compressed and expanded externally. The expansion displacement of the arched metal plate is compensated by the swing effect of the swing hanging pieces. When the external force is eliminated, the running board is returned back to its original position by the restoring ability of the arched metal plate so that an expected and optimal cushioning effect is achieved.
Description
- 1. Fields of the Invention
- The invention relates to a cushioning mechanism for a treadmill, and more particularly, to a structure employing the excellent restoring ability of an arched metal plate in conjunction with a synchronous swing of a hanging device to compensate the expansion displacement for achieving an excellent cushioning effect.
- 2. Description of the Related Art
- It is well-known that the cushioning effect of the conventional treadmills is mostly created by a plurality of rubber pads between the running board and the treadmill's base frame. In this way, these rubber pads provide a certain cushioning effect to properly withstand all reactive forces acting on the treadmill's operator when the running board is subject to an external force.
- These rubber pads may produce the cushioning effect to some extent. However, it is an indisputable fact that they can be qualitatively changed due to the environmental and time factors. In particular, their durability tends to be different according to forces acting thereon. That is, their service life will be significantly impaired in case of the prolonged exposure to large pressure.
- Moreover, the rubber pads are positioned in a hidden place. When they are repaired or replaced, the running belt and the running board have to be removed. Therefore, it is not easy for the general users to conduct the above-mentioned complicated steps. This requires further improvements.
- An object of the invention is to provide a cushioning mechanism for a treadmill that employs a metal plate with an excellent responsiveness, a great restoring ability, and a high tolerance to replace most of the rubber pads. Moreover, a hanging device movable with the metal plate is used to absorb the displacement of the metal plate when subject to an external force. In this way, an excellent cushioning effect is achieved. In addition, when the metal plate is required to be replaced, it is only necessary to remove the continuous moving belt for conducting the replacement work. As a result, a convenient replacement is ensured.
- According to the invention, at least one set of the cushioning mechanism is interposed between a base frame and a running board. The cushioning mechanism includes two support hanging pieces, two swing hanging pieces, an arched metal plate. The top surface of the arched metal plate is just in contact with the bottom surface of the running board. When the running board is subject to a downward force and sink, the arched metal plate mounted below will be compressed and expanded externally. The expansion displacement of the arched metal plate is compensated by the swing effect of the swing hanging pieces. When the external force is eliminated, the running board is returned back to its original position by the restoring ability of the arched metal plate so that an expected and optimal cushioning effect is achieved.
- 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 a preferred embodiment of the invention; -
FIG. 2 is a schematic drawing of the assembly position of the invention according toFIG. 1 ; -
FIG. 3 is a schematic drawing of the invention according toFIG. 2 in a compressed position. - 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
FIG. 1 , thecushioning mechanism 20 is installed in a hidden way under a runningboard 12 of thetreadmill 10. A continuous movingbelt 14 is positioned around the runningboard 12. The drawing ofFIG. 1 is used to illustrate the installation position of the invention. - As shown in
FIG. 2 , at least one set of thecushioning mechanism 20 is interposed between abase frame 16 and the runningboard 12. Thecushioning mechanism 20 includes twosupport hanging pieces 22, twoswing hanging pieces 24, and anarched metal plate 26. - The
support hanging pieces 22 each have one end fixed at thebase frame 16 and the other end pivotably connected to theswing hanging pieces 24. - The
swing hanging pieces 24 are mounted in a hanging way with the bottom end pivotably connected to thearched metal plate 26. - The
arched metal plate 26 is constructed in the form of curvature with both ends thereof pivotably connected theswing hanging pieces 24 and with the top surface just in contact with the bottom surface of the runningboard 12. - Based on the assembly of the above-mentioned components, as shown in
FIG. 3 , when the runningboard 12 is subject to a downward force and sink, thearched metal plate 26 mounted below will be compressed and expanded externally. The expansion displacement of thearched metal plate 26 will be compensated by the swing effect of theswing hanging pieces 24. When the external force is eliminated, the runningboard 12 will be returned back to its original position by the restoring ability of thearched metal plate 26. In this way, an expected and optimal cushioning effect is achieved. - As shown in
FIG. 1 ,conventional rubber pads 18 are also mounted (at four corners) between the runningboard 12 and thebase frame 16. They tend to work with thecushioning mechanism 20 of the invention to achieve a double cushioning effect. - 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.
