发明名称 Structural improvement for stretching exercise apparatus
摘要 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.
