Description

Leg stretch body

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an exercise device, particularly a leg extension body that allows the inner and outer sides of the leg to move sufficiently to achieve muscle and tendon extension.

The well-known fitness device structure has many kinds of designs for muscle training of various parts of the body, and the operation methods of the legs are running, thigh-clamping, stepping, lacing, etc. An exercise machine for stretching the inner and outer muscles and tendons.

Therefore, the present inventors have succeeded in creating a kind of experience that can be complemented by the above-mentioned lack of functions of the above-mentioned conventional body, by years of research and manufacturing experience in related fields, after detailed design and careful evaluation. The innovative structure of the function, and more ideal and practical. Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide a leg extension body protector to solve the problem of conventional bodyguards! 3⁄4 points to provide more different modes of movement to increase the selectivity of more movement modes.

Technical feature of solving the problem: a leg stretching body, characterized in that:

a base, the base comprises a cross bar and a middle seed; a telescopic device is fixed on the base, and a pulley device and a pivoting portion are respectively arranged on both sides of the rod in the base;

The two side frames can be extended and closed, and the two side frames respectively include a fixed end, a rod and a plurality of connecting portions connecting the fixed end and the seat post; the fixed ends of the two side frames are pivotally connected to the base and the rods are respectively inverted. Pivot, and,

The two-foot pedal has a sliding device at the bottom of the two-footed pedal, and a limit stop device and a hook ear for preventing the foot pedal from sliding out of the limited range, the sliding device includes a roller device and a clamping device, the foot The sliding groove of the pedal bottom sliding device S and the sliding device of the roller device are located at the side frame connecting portion; a resistance member is hooked on the bottom hook of the foot pedal, and the other end of the resistance member is wound around the middle rod On the side of the pulley device, the other end of the resistance member is hooked to the side of the stalk corresponding to the hook.

The handlebar telescopic device comprises a connecting tube, an adjusting tube, a fixing component and a handle, the connecting tube is located above the base, and an adjusting tube is inserted in the connecting tube, and a handle is arranged at the top of the adjusting tube The lower part of the adjusting tube is provided with a plurality of adjusting holes from top to bottom, and the connecting tube is provided with a penetrating portion, and a national component for fixing the adjusting tube is placed on the penetrating portion and the adjusting hole. One adjustment hole.

Among them, the resistance member is 'elastic without piece.

Wherein, the connecting portion formed between the fixed end of the side frame and the seat post has a concave arc shape. Wherein, the limit limiting device comprises a blocking rod and a blocking body, the blocking rod is fixed on the bottom of the pedal, and the limit of the blocking body fixed in the connecting portion blocks the blocking rod position.

In this way, the two feet can be stepped on the pedals respectively, and then the force of the two feet is used to make the pedals move to the two horizontally different directions, and the resistance is reversely pulled to make the two legs move. The force of the force makes the inner side of the thigh have a good fitness effect.

Compare the efficacy of the prior art:

Generally used exercise machines, such as running, thigh-clamping, squatting, lacing, lifting legs, etc., less fitness equipment with both inner and outer thigh muscles and leg stretching exercises Most of the fitness people train their legs in a long time running with a short stretch of lacing. Usually the leg muscles are concentrated in a certain part of the hook.

The present invention includes a base having a first side frame and a second side frame on both sides of the base, and each of which is provided with a first foot pedal and a second foot pedal thereon, the foot pedal Sliding to the horizontal direction and the bottom of the pedal is provided with a resistance member (as shown in Figure 3). When in use, place the two feet on the pedals and expand in two different directions. Force, combined with the damper tension generated by the resistance member, to train the inner and outer muscles of the thigh and strengthen the veins, which is of great help to the shaping of the legs.

The leg fitness structure of the present invention, wherein the first side frame and the second side frame are pivotally connected to the base, and may be vertically folded (as shown in FIG. 4) or horizontally expanded, such that The first side frame and the second side frame are folded horizontally and vertically, which can greatly reduce the occupied space and increase the convenience of storage, and is a creation with both new ideas and business opportunities.

With regard to the techniques, means and efficiencies employed in the present invention, a preferred embodiment will be described in detail in conjunction with the circumstance, in order to provide an in-depth and specific understanding of the above-described objects and features of the present invention.
