Structural improvement for stretching exercise apparatus

Abstract

A structural improvement for stretching exercise apparatus comprises a carry handle pivotally connected symmetric long bottom seats, upper surfaces of the long bottom seats having symmetric guiding slots near two long side edges; at least two sets of symmetric casters, disposed to bottom portions of two pedals, for fitting the symmetric guiding slots; and two flexible riggings disposed inside the two long bottom seats. The feature of the apparatus is that a long channel is disposed between the symmetric guiding slots and upper surfaces of the symmetric long bottom seats. A plurality of symmetric positioning circular holes is disposed to two sides of the long channel. A limit seat has four end angles equipped with cylinders. Accordingly, the distance variations generated by the pedal relatively moving within the guiding slot can be changed by regulating the cylinders of the limit seat inserted into the positioning circular holes at different positions.

Description

FIELD OF THE INVENTION[0001]The invention relates to a structural improvement for stretching exercise apparatus that provides two feet of a user respectively standing on symmetric pedals and then configures the symmetric pedals based upon self demands of the user to achieve the goal of exercising leg functions of the user thorough resistance forces generated by outwardly unfolding or inwardly folding the pedals at the same time.BACKGROUND OF THE INVENTION[0002]A conventional exercise structure, entitled as “Multifunctional sliding fitness equipment”, includes a bottom plate taken as a main body. Sliding rails are formed on the bottom plate. A pair of foot pedals having casters is crossed over the rails of the bottom plate. The characteristics of the exercise structure are that: the bottom plate is butted with two long strip plates and connected with a hinge. The hinge toggle joint disposed to other surfaces of the two long strip plates are passed by a flexible rope. A hanging ring i...

AI Technical Summary

Benefits of technology

[0005]A primary objective of the invention is to provide a structural improvement for stretching exercise apparatus that could regulate symmetric pedals to unfold toward outside or to fold toward inside simultaneously so as to achieve the variation for stroke distance.

[0006]Another objective of the invention is to provide a structural improvement for stretching exercise apparatus. When the symmetric pedals slide along paths stroke, elastic pads are fixedly disposed to two terminals of the path strokes and lean against the pedals to absorb shock and to generate buffer effect.

[0009]Moreover, an elastic pad is respectively disposed to terminals of two short side edges of each long channel on the long bottom seat and is provided for leaning against the casters of the bottom portion of the pedal to absorb shocks and to generate buffer effect.

Problems solved by technology

However, the foregoing sliding fitness equipment has some problems that need to be overcome.

Although many regulation holes disposed to relative outer ends of the bottom plate can be passed by the blocking rack, the defect of difficulty inserting the blocking rack into the regulation holes under tightening condition may happen.

The blocking rack may be loosened under loosening condition and result in noise while touching the blocking rack.

Consequently, while performing expansion or drawing close to each other, the foot pedals may be improperly shifted toward a single side of the bottom plate due to non-uniform applied force and subsequent exercises are impeded.

When the flexible ropes generate elastic fatigue, the flexible ropes may easily fall into the rails to form the obstruction that the rollers disposed to the bottom portion of the foot pedals may not smoothly pass through during stretching and retracting processes.

The user may easily fall from the fitness equipment to suffer injuries.
