Exercise bench

Abstract

An exercise bench includes a support frame, a first pad body and a second pad body. The support frame has a guide rod. The first pad body and the second pad body are pivotally mounted to the support frame at a first pivot and a second pivot respectively. Specifically, a link member is pivotally mounted to the first pad body at a first pivotal fulcrum and movably mounted to the guide rod at a sliding fulcrum for sliding along the guide rod. In addition, a support member is pivotally mounted to the support frame at a third pivot, and has a telescopic post being pivotally mounted to the second pad body at a second pivotal fulcrum. Particularly, a link rod pivotally connects the link member and the support member to form a linkage such that the first pad body and the second pad body are synchronized with each other.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present disclosure relates to an exercise apparatus. More particularly, the present disclosure relates to an exercise bench with a linkage mechanism.[0003]2. Description of the Related Art[0004]An exercise bench is an equipment design to provide a support for use in weight training or other exercise training Generally, the conventional exercise bench includes a seat for supporting a user's buttocks and a seat back for supporting the user's back. The seat and the seat back are pivotally mounted to a frame such that the inclined angles of them could be adjusted. However, when the user wants to adjust the exercise bench, the user needs to adjust the inclined angles of the seat and the seat back respectively, which is inconvenient to use.[0005]One type of exercise bench is shown in U.S. Pat. No. 7,674,215, which includes a seat and a seat back each pivotally mounted to a support frame at respective first and second stationary pivots. Pa...

AI Technical Summary

Benefits of technology

The present invention is an improved exercise bench that allows for synchronized motion between two pad bodies without interfering with each other. The linkage mechanism includes a support frame, two pad bodies, a link member, a support frame, and a link rod. The link member has a first pivotal fulcrum, a first connecting fulcrum, and a sliding fulcrum. The support member has a telescopic post with an inner tube and an outer tube, and a lock pin for adjusting the length of the telescopic post. The link member also has a connecting arm and a mounting tab for sliding along a guide rod. The guide rod is secured to the support frame and the telescopic post has positioning holes and a lock pin for locking the telescopic post and inner tube relative to each other. The linkage mechanism allows for synchronous motion of the pad bodies. The first pad body is a seat and the second pad body is a seat back. The first pivotal fulcrum between the seat and the link member is located close to the rear end of the seat, and the second pivotal fulcrum between the seat back and the telescopic post is located close to the rear end of the seat back. The technical effects of the invention include synchronized motion between the pad bodies, improved stability, and adjustable inclined positions of the second pad body.

Problems solved by technology

However, when the user wants to adjust the exercise bench, the user needs to adjust the inclined angles of the seat and the seat back respectively, which is inconvenient to use.

However, the conventional exercise bench still has one disadvantage as following.

The linkage mechanism between the seat and the seat back just relies on gravity for tacking on a slide of the seat back, which is not stable during exercise training Moreover, if this similar mechanism be tilted up for different applications, it may not be fully operable.
