Thereby, a user can step both feet on the pedal plates and move the pedal plates outwardly in horizontal direction. Furthermore, by utilizing the resistance member to provide resistance, such resistant force generated while exercising enhances the exercising effect as both the interior and exterior thigh muscles of the user are effectively trained.
Effects of the present invention compared to the prior art:
1. Regarding leg training, there are several operating types with respect to exercisers such as running-type, thigh clipping-type, stepping-type, stretching-type and the like. Conventional exercisers don't combine training the interior and exterior thigh muscles and stretching the tendons and muscles. Therefore, exercisers often exercise and train their legs by a long period of time of running combined a short period of time of stretch. The muscles of the legs usually are exercised focally at some certain parts and are not evenly exercised.
2. The present invention includes a base seat comprising a first side frame and a second side frame respective at two sides. Further, a first pedal plate and a second pedal plate are mounted on the base seat. The pedal plates can be slid in horizontal direction and there is a resistance member mounted under the pedal plates (as shown in FIG. 3). When it is in use, a user can step both feet on the pedal plates and move the pedal plates outwardly in horizontal direction. Furthermore, by utilizing the resistance member to provide resistance, the resistant force generated while exercising enhances the exercising effect as both the interior and exterior thigh muscles of the user are effectively trained. The present invention combines training the interior and exterior leg muscles and stretching the tendons and muscles, thus, it greatly helps shaping the legs.
3. Regarding the leg stretching exercise apparatus of the present invention, the first side frame and the second side frame are hinged to the base seat and can be vertically folded (as shown in FIG. 4) or horizontally folded. Therefore, the first side frame and the second side frame can be vertically folded to decrease the occupying space by a wide margin and is more convenient to store. Thus, the present invention is a novel product with commercial values.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

Regarding the leg stretching exercise apparatus of the present invention, the first side frame 20 and the second side frame 30 are hinged to the intermediate shaft 12 of the base seat 10 and can be vertically or horizontally foldable. Therefore, the first side frame and the second side frame can be vertically folded to decrease the occupying space by a wide margin.
Furthermore, the resistance member 40 is an elastic element.
Referring to FIGS. 2-3, with respect to the leg stretching exercise apparatus, the telescopic handle 13 is mounted at a front end of the base seat 10. The first side frame 20 and the second side frame 30 are respectively hinged to both sides of the base seat 10. The first side frame 20 and the second side frame 30 respectively includes the first fixed end 21, the second fixed end 31 and the first base shaft 22, the second base shaft 32 and the connecting members 50 respectively connecting between the first fixed end 21 and the first base shaft 22 and between the second fixed end 31 and the second base shaft 32. The connecting member 50 is downwardly curved. The first fixed end 21 of the first side frame 20 and the second fixed end 31 of the second side frame 30 are hinged to the hinge members 121 of the base seat 10. The first pedal plate 23 and the second pedal plate 33 both include the sliding member 60 and the limit device 70. The crooks 63 are mounted at the bottom of the first pedal plate 23 or the second pedal plate 33. The sliding member 60 includes wheels 62 and limit pieces 61. The first pedal plate 23 or the second pedal plate 33 is limited on the connecting member 50 by the limit pieces 61 of the sliding member 60 to enable the first pedal plate 23 or the second pedal plate 33 to slide on the connecting member 50. One end of the resistance member 40 is hooked onto crooks 63 under the first pedal plate 23 or the second pedal plate 33 and mounted around the pulley sets 122 of the intermediate shaft 12. The other end of the resistance member 40 is hooked onto the corresponding crooks 64 of the first base shaft 22 or the second base shaft 32. The resistance member 40 can be an elastic rope. The resistance member 40 can provide appropriate resistance for the horizontal movement of the first pedal plate 23 or of the second pedal plate 33. The limit device 70 includes a block shaft 71 and a block body 72. The block shaft 71 is mounted at the bottom of the first pedal plate 23 or the second pedal plate 33. The block body 72 is fixed on the connecting member 50 to limit the block shaft 71. Therefore, the limit device 70 can limit the first pedal plate 23 or the second pedal plate 33 to move in a desired domain.
Besides, referring to FIG. 3, the first side frame 20 and the second side frame 30 are hinged to the base seat 10 and can be vertically or horizontally folded. Therefore, the first side frame and the second side frame can be vertically folded to decrease the occupying space by a wide margin and is more convenient to store.
When in use, the user steps on the leg stretching exercise apparatus and hold the handle 142 of the telescopic handle 13. The user steps both feet on the pedal plates 23, 33 and moves the pedal plates 23, 33 outwardly in horizontal direction. The first pedal plate 23 and the second pedal plate 33 slide on the connecting member 50. The first pedal plate 23 and the second pedal plate 33 are both pulled by the resistance member 40. The user has to exert with force that is greater than the pull force and thus successfully move the pedal plates 23, 33 outwardly in horizontal direction. When the user sets free the pedal plates 23, 33, the pedal plates 23, 33 will be pulled back by the resistance member 40 to the original position. Thus, by utilizing the repeated action of pull and release, the user exercises and stretches the muscles and tendons. It is also good for shaping the legs and enhancing the exercising effect of the interior and exterior thigh muscles.
To conclude, the present invention has efficacy and practical value and can improve the economic value. The present invention is distinguished from the prior art. Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
