Description

FIELD OF THE INVENTION

The present invention relates to a leg stretching device, and more particularly, to a leg stretching device which is able to adjust the tension of the resilient bands and the angle for stretching.

BACKGROUND OF THE INVENTION

There are many exercisers providing different functions for training different parts of the users' body, such as treadmills, sit-ups exercisers, weight-lifting exercisers, and pull-up exercisers. However, there is no such a device for stretching user's legs. A conventional leg stretching device cannot adjust the tension of the resilient bands and the angle of how the users can stretch their legs, and this makes the exercising to be boring and the users tend to give up the use of the conventional leg stretching device.

The present invention intends to provide a device that provides at least two resilient bands for stretching the user's legs and the tension of the resilient bands can be adjusted according needs. The user can also adjust the angle of stretching so as to stretch different part of muscles of legs.

SUMMARY OF THE INVENTION

The present invention relates to a leg stretching device and comprises a frame having multiple lugs on two sides thereof and first and second pedals are pivotably connected to the lugs respectively. Two first protrusions extend from the first and second pedals respectively and two side extensions respectively extend from two ends of the frame. A rod is connected to the mediate portion of the frame by an angle adjusting member. Two second protrusions extend from two sides of the rod respectively. Two resilient bands are respectively connected to the two first protrusions and the two second protrusions. The angle adjusting member adjusts tensions of the two resilient bands. Two extension portions are respectively connected to the two side extensions and each extension portion has a support rod connected thereto. The first and second pedals each have multiple positioning holes facing the support rod so as to adjust the angle for stretching.

The primary object of the present invention is to provide a leg stretching device wherein the tension of the resilient bands of the device and the angle for stretching can be adjusted.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 6, the leg stretching device of the present invention comprises a frame 10 having multiple lugs 11 on two sides thereof First and second pedals 20, 30 each have a free end pivotably connected to the lugs 11. Two first protrusions 21, 31 extend from the first and second pedals 20, 30 respectively so as to stably put the frame 10 on a floor. Two side extensions 12, 13 respectively extend from two ends of the frame 10.

A rod 40 is connected to the mediate portion of the frame 10 by an angle adjusting member 60 and two second protrusions 41, 42 extend from two sides of the rod 40 respectively. Two resilient bands 50, 51 are respectively connected to the two first protrusions 21, 31 and the two second protrusions 41, 42. The angle adjusting member 60 is able to adjust tensions of the two resilient bands 50, 51.

Two extension portions 71, 72 are respectively connected to the two side extensions 12, 13 and each extension portion 71/72 has a support rod 73/74 connected thereto. The first and second pedals 20, 30 each have multiple positioning holes 22/32 facing the support rod 74/73 so as to adjust the stretching angles.

A through hole 61 is defined in the rod 40 and two fan-shaped plates 62, 63 are respectively located on two sides of the rod 40 and located corresponding to the through hole 61. Each fan-shaped plate 62/63 has multiple curved notches 64. A pin 65 extends through the through hole 61 and engaged with one of the curved notches 64 of each of the fan-shaped plates 62, 63 to set up an angle of the rod 40 relative to the frame 10 so as to adjust the tension of the resilient bands 50, 51.

As shown in FIGS. 3 and 5, the angle adjusting member 60 adjusts the rod 40 relative to the frame 10 so as to adjust the tension of the resilient bands 50, 51 such that the users obtain different resistance when treading the first and second pedals 20, 30. As shown in FIGS. 4 and 6, by engaging the support rods 73, 74 with the positioning holes 22, 32 located at the underside of the first and second pedals 20, 30, the stretching angle can be adjusted.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
