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...
