Abstract
Description
- The present invention relates to exercise treadmills, and more particularly to a treadmill utilizing cushioning members that cushion the impact caused by users when exercising on the treadmill.
- It is well established that regular exercise is beneficial. Many exercise enthusiasts, especially those who are older, prefer low impact exercise that results in reduced foot impact shocks to the legs and leg joints as compared to running on a hard surface.
- Treadmills allow individuals to walk or run indoors by moving a continuous belt about two rollers. The user walks or runs on the belt, which passes over the supporting deck that supports the user's body weight. The speed of the belt may be controlled by a motor.
- Early treadmill designs used supporting decks that were rigidly attached to a frame. Typically, the frame was not provided with a shock absorber for absorbing the shock of foot impact. Recently, treadmills have been introduced that utilize a mechanism to absorb some of the impact generated by a user striking the treadmill while running or walking. Various mechanisms have been implemented for impact absorption.
- It is desirable to provide a treadmill cushion mechanism that is simple and low cost, yet effective for reducing impact.
- A treadmill is described herein that includes a frame for supporting an endless belt. A forward structure is provided for supporting a first end of the frame. The forward structure preferably includes a base structure, a vertical member attached to the base structure, and a console attached to the vertical member. Examples of typical treadmills include “fold on roller” types, wherein a frame may be pivoted upwardly, but wherein the motor remains in its original position. An example of another type of treadmill is a type wherein an entire unit pivots upwardly with respect to the forward structure, including the motor. For purposes of this application, in each embodiment, the first end of the frame is defined as the end nearest the forward structure, while the second end of the frame is defined as the opposite end, which is raised when the frame is folded into an upright configuration.
- A pivoting structure is provided proximate a second end of the frame for supporting the second end of the frame and for cushioning impacts delivered to the frame by running or walking on the belt. The pivoting structure includes a pivot arm having a secured end and a free end, wherein the secured end is pivotally affixed to the frame. The pivot arm preferably has a left flange and a right flange. A roller is mounted on a roller axle proximate the free end of the pivot arm. The pivoting structure is preferably mounted on a pivot anchor provided on an underside of the frame. The left flange and the right flange of the pivot arm are connected via a spanning member that defines an orifice.
- A spring is provided that has a first end in communication with the frame and has a second end in communication with the pivot arm for biasing the pivot arm away from the frame. A limiter anchor is provided proximate the second end of the frame that extends from an underside of the frame. A limiter is received within the limiter anchor and passes through the orifice of the spanning member. Preferably, the spring surrounds the limiter. The limiter preferably has a head that engages the spanning member for limiting the maximum amount of travel that the pivot arm can extend away from the frame.

FIG. 2 is an enlarged perspective view of the pivoting support structure shown extending beneath a treadmill frame of the treadmill ofFIG. 1 . -
FIG. 3 is an enlarged elevational view of the pivot support structure ofFIG. 1 . -
FIG. 4 is an enlarged partial cross-sectional elevation view of the pivoting support structure ofFIG. 1 . - Referring first to
FIG. 1 , an elevational view of a treadmill is shown, designated generally 10.Frame 12 is provided for supporting anendless belt 11 that functions as a moving surface upon which an exerciser may run or walk. The endless belt is typically mounted onforward roller 14 andrearward roller 16.Frame 12 has afirst end 18 and asecond end 20.Frame 12 is provided with apivot anchor 22 and alimiter anchor 24, each of which are proximatesecond end 20 offrame 12. Pivot anchor 22 (FIGS. 1-7 ) and limiter anchor 24 (FIGS. 1-6 ) each extend from an underside offrame 12. - A forward structure, as shown in
FIG. 1 , is designated generally 26.Forward structure 26 is provided for supportingfirst end 18 offrame 12.Forward structure 26 includes abase structure 30.Vertical member 32 extends upwardly frombase structure 30. Typically, aconsole 34 is provided on an upper end ofvertical member 32.Hand grips 36 may be provided that extend fromforward structure 26. A plurality offeet 38 are typically provided to supportforward structure 26. - Rear support or pivoting structure 40 (
FIGS. 1-7 ) is provided to supportsecond end 20 offrame 12.Pivoting structure 40 includes apivot arm 42. Pivot arm 42 (FIGS. 1-7 ) has a securedend 44 and afree end 46. Securedend 44 is pivotally affixed topivot anchor 22 bypivot axle 48.Pivot arm 42 is provided with aleft flange 50 and aright flange 52.Left flange 50 andright flange 52 are connected to one another via spanningmember 54. Spanning member 54 (FIGS. 4 and 7 ) defines an orifice 56 (FIGS. 4 and 7 ). A limiter such asbolt 58 is preferably threadably received withinlimiter anchor 24. Bolt 58 passes throughorifice 56 of spanningmember 54. Bolt 58 includes a head 60 (FIGS. 2-6 ) that engages spanningmember 54 for limiting travel ofpivot arm 42 away fromframe 12.Spring 62 surroundsbolt 58 for biasingpivot arm 42 away fromframe 12. Aroller 64 is mounted onroller axle 66 onfree end 46 ofpivot arm 42. - In one embodiment (
FIGS. 5-7 ),spring 62 is surrounded withelastomeric sleeves 68 to assist in resisting compression ofspring 62. - In use, a user stands on the endless belt mounted on
frame 12. During exercise,spring 62, which supportsframe 12 and the weight of the user, will be compressed, allowing for movement ofpivoting structure 40 on a right and left side offrame 12.Spring 62 and/orpolymer sleeves 68 absorb some of the impact of the user's weight onframe 12, thereby absorbing energy and decreasing the amount of impact stress on a user's feet and legs. - The amount of compression resistance may be adjusted by rotating
bolt 58 to either increase or decrease compression ofspring 62.Roller 64 allows forpivot arm 42 to pivot freely aboutpivot axle 48, which permitsframe 12 to be easily flexed, which in turn allowssecond end 20 offrame 12 to move toward and away from a floor surface as required to absorb impact. - Thus, the present invention is well adapted to carry out the objectives and attain the ends and advantages mentioned above as well as those inherent therein. While presently preferred embodiments have been described for purposes of this disclosure, numerous changes and modifications will be apparent to those of ordinary skill in the art. Such changes and modifications are encompassed within the spirit of this invention as defined by the claims.
