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.

Claims

1. A stretching exercise apparatus comprising:

a carry handle having two ends pivotally connected to symmetric long bottom seats, two short side edges of the long bottom seats having symmetric roller sets covered with an outer cover, upper surfaces of the long bottom seats having symmetric guiding slots near two long side edges of the long bottom seats, at least one long channel disposed between the symmetric guiding slots, two sides of the two long channels having multiple symmetrically positioning circular holes spaced at equivalent intervals and near correspondingly outer ends of the long bottom seats;

at least two sets of symmetric casters, disposed to bottom portions of two pedals, for fitting the symmetric guiding slots, two sides of the pedal having two sets of symmetric fastening slots;

a plurality of flexible riggings respectively disposed inside the two long bottom seats, at least one flexible rigging having two ends wound to rears of the roller sets, blocking members connected to ends of the flexible riggings and capable of being blocked to an upper portion of the outer cover or regulated in the fastening slots at corresponding ends of the pedals; and

a limit seat having cylinders at four end angles of a bottom portion of the limit seat, the four cylinders fit to the positioning circular holes of two sides of the long channels so that variations of strokes and distances generated by the pedals relatively moving within the guiding slots are changed by regulating each cylinder of the limit seat inserted into the positioning circular holes at different positions.

2. The stretching exercise apparatus as claimed in claim 1, wherein a limit plate is locked to a center position of the bottom portion of the pedal, and an upper portion of the limit plate has symmetric connection cylinders that are accommodated in the long channel of the long bottom seat, and a width of the limit plate is greater than a width of the long channel so that the pedal is limited by a blocking of the limit plate.

3. The stretching exercise apparatus as claimed in claim 2, wherein two sides of the limit plate has two axles, and a portion of upper surfaces of the two axles is attached to a bottom surface of the long channel.

4. A stretching exercise apparatus comprising:

a carry handle having two ends pivotally connected to symmetric long bottom seats capable of being horizontally unfolded and folded, two long side edges of upper surfaces of the long bottom seats having symmetric guiding slots;

two pedals, wherein bottom portions of the two pedals respectively have at least two sets of symmetric casters fit to the symmetric guiding slots, and two sides of upper portions of the pedals have two sets of symmetric fastening slots;

at least one or more than one flexible rigging disposed inside the two long bottom seats, at least one flexible rigging having two ends respectively connected to a blocking member capable of being blocked to an outer cover of the long bottom seat or regulated in the fastening slots of corresponding end of the pedal to allow the pedal to generate a damper effect.

5. The stretching exercise apparatus as claimed in claim 4, wherein two short side edges of the long bottom seat comprise a symmetric roller set capable of being wound by the flexible rigging.

6. The stretching exercise apparatus as claimed in claim 5, wherein an upper portion of the symmetric roller set is covered with an outer cover.

7. The stretching exercise apparatus as claimed in claim 4, further comprising at least one long channel disposed between the symmetric guiding slots on upper portion of the symmetric long bottom seat, a plurality of symmetric positioning circular holes spaced at equivalent intervals and disposed to two sides of the two long channels, two limit seats respectively connected to the long bottom seat, wherein four end angles of a bottom portion of the limit seat comprise four cylinders, and the four cylinders are fit to the plurality of positioning circular holes at two sides of the long channel so that variations of stroke and distance generated by the pedal relatively moving within the guiding slot are changed by regulating each cylinder of the limit seat inserted into the plurality of positioning circular holes at different positions.

8. The stretching exercise apparatus as claimed in claim 7, wherein a side of an upper end of the limit seat comprises a flexible pad for relatively leaning against the pedal.

9. The stretching exercise apparatus as claimed in claim 4, wherein elastic pads are fastened to two ends of each guiding slot of the long bottom seat and leaning against the casters to absorb shocks and generate buffer effects.

10. The stretching exercise apparatus as claimed in claim 7, wherein a side of an upper end of the limit seat has a circular aperture;

and a circular cylinder is extended from a bottom portion of a regulation member to fit in the circular aperture to perform an angle rotation, and a long blocking plate is formed from a terminal of the circular cylinder, and a short edge of the long blocking plate is smaller than a width of the long channel of the long bottom seat, and a long edge of the long blocking plate is greater than the width of the long channel.

11. The stretching exercise apparatus as claimed in claim 7, wherein symmetric blocking pieces are disposed to a predetermined inclined diagonal at a circumference of the circular aperture on an upper end of the limit seat and provided for leaning against and limiting the regulation member.
