Description

Technical Field

[0001] The present invention relates to a lower limb exercise device, and more particularly to a functional lower limb exercise device capable of achieving a concentrated exercise effect on the buttocks and thighs. Background Art

[0002] Typically, lower limb exercise equipment uses treadmills, step-type, swing-type, and leg-press type exercise equipment.

[0003] This type of exercise equipment is used to strengthen the lower limb muscles or perform whole-body aerobic exercise. Most of them are mainly used to strengthen the rectus femoris, medial and lateral muscles and other muscles with external rotation tendencies.

[0004] However, if this type of exercise uses sports equipment for a long time or is used improperly, it may damage joints such as the knees and ankles, and cause muscle pain or inflammation.

[0005] Therefore, there is an urgent need for an exercise device that can minimize damage to joints or ankles and strengthen or rehabilitate thigh and buttocks muscles. Summary of the Invention

[0006] Technical issues

The purpose of the present invention is to provide a sports equipment that can minimize the burden on the knees or joints and achieve concentrated exercise on the thighs and buttocks, thereby maximizing exercise efficiency.

[0008] Technical Solution

[0009] In order to achieve the above-mentioned purpose, the sports equipment of the present invention is characterized in that it includes: an equipment body, which is formed with an inclined surface whose height gradually decreases toward the left and right sides with the center as the reference; a knee pad and a shin guard pad placed on the inclined surface of the equipment body in a manner that can be moved left and right; an elastic spring, which is arranged inside the equipment body and is used to elastically support the knee pad and the shin guard pad; and a movable roller, which is arranged at the lower part of the knee pad and the shin guard pad so as to move smoothly along the inclined surface.

[0010] Effects of the Invention

[0011] The lower limb exercise equipment of the present invention can minimize the burden on the joints of the knees or ankles and achieve a concentrated exercise effect on the thighs and buttocks.

[0024] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. This embodiment is provided to more fully explain the present invention to those skilled in the art.

[0026] Therefore, the shapes of structural elements shown in the drawings may be exaggerated for clarity. It should be noted that identical structures may be represented by the same reference numerals across the drawings. Furthermore, if it is determined that the functions and structures of known technologies may unnecessarily obscure the main points of the present invention, their detailed description may be omitted.

[0027] First, refer to Figures 1 to 7 The structure of the lower limb exercise equipment of the first embodiment of the present invention is as follows.

[0028] The lower limb exercise equipment in this embodiment includes: an equipment body 10, which is formed with an inclined surface 11 whose height gradually decreases to the left and right sides with the center as the reference; a knee pad 20, which is placed on the inclined surface 11 of the equipment body 10 in a manner that can be moved left and right; an elastic spring 30, which is arranged inside the equipment body 10 and is used to elastically support the knee pad 20; and a movable roller 22, which is arranged at the lower part of the knee pad 20 so that it can move smoothly along the inclined surface.

[0029] In this case, a spring connecting rod 23 connected to an elastic spring 30 is connected to the knee and shin pads 20 , and a guide groove 13 of a predetermined length is formed on the upper inclined surface 11 of the device body 10 to guide the movement of the spring connecting rod 23 .

[0030] Furthermore, it can be confirmed that a guide groove 12 for guiding the moving roller 22 is formed on the upper surface of the device body 10 .

[0031] The following will describe the effects of using the lower limb exercise equipment of the present invention having the above structure.

[0032] The exercise apparatus of the present invention allows a user to exercise with his knees placed on the knee and shin pads 20 .

[0033] That is, when the thighs and buttocks are exerted to push the knee and shin pads 20 on both sides outward, the knee and shin pads 20 on both sides will move outward along the inclined surface 11 . In this case, the spring connecting rod 23 will be guided along the guide groove 13 .

[0034] Furthermore, when the force applied to the knee and shin pads 20 is released, the knee and shin pads 20 return to their original positions due to the elastic restoring action of the elastic springs 30. By repeating this action, the thigh and buttock muscle strengthening exercises can be performed efficiently.

[0035] Therefore, the lower limb exercise equipment of the present invention can minimize the burden on the joints of the knees or ankles and achieve a concentrated exercise effect on the thighs and buttocks.

[0036] In particular, the shin guard provides support in a kneeling position, allowing the user to exercise in a lower posture, thereby reducing the weight pressure on the upper body and allowing the user to exercise easily at home or indoors.

[0037] on the other hand, Figure 8 and Figure 9 The structure of the second embodiment of the present invention is shown. The device body 10 is a foldable storage structure, divided into left and right parts and connected by a hinge 40.

[0038] Furthermore, a protective layer 15 is coated on the sidewall of the device body 10 to prevent slipping on the ground and protect the surface. In this case, preferably, the protective layer 15 is composed of a mixture of 10 to 30 weight percent of vinyl acetate resin, 5 to 20 weight percent of polyurethane powder, 1 to 10 weight percent of phenylene ether, 10 to 30 weight percent of furan resin, 1 to 10 weight percent of polytetrafluoroethylene, 10 to 20 weight percent of thermoplastic elastomer, 5 to 15 weight percent of barium sulfate, and 1 to 15 weight percent of sericite powder.

[0039] If the above structure is realized, the side wall surface of the device body 10 is coated with the protective layer 15, thereby preventing the surface from being damaged and Figure 9 As shown, when folded and stored, the folded state can be kept stable due to the friction with the ground.

[0040] In particular, the present invention offers the following advantages: The phenyl ether and furan resin components mixed into the protective layer 15 prevent moisture penetration; polytetrafluoroethylene improves coating elasticity by catalyzing the vinyl acetate resin; and polyurethane powder and thermoplastic elastomer enhance the surface friction and heat resistance of the protective layer 15. Furthermore, the additional additions of barium sulfate and sericite powder increase the coating density of the protective layer 15, thereby improving surface durability.

[0041] and, Figure 10 The third embodiment of the present invention is shown. It can be confirmed that a handle 50 of a predetermined height is connected to the center of the instrument body 10 .

[0042] If the above structure is implemented, during the lower limb exercise, the user can hold the handle 50 to prevent the upper body from shaking, thereby achieving a more stable lower limb exercise.

[0043] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is apparent that a person skilled in the art can implement the lower limb exercise equipment of the present invention after making various modifications to the structure.

[0044] For example, in the embodiment described, the roller 22' can be moved as follows Figure 11 The aforementioned configuration moves along the guide rail 14 so that the knee and shin pads 20 can move smoothly.

[0045] And, as Figure 12 As shown, the guide groove 12 can be formed into a curved shape according to the human body structure.

[0046] Therefore, the modified embodiments should not be understood separately from the technical idea or scope of the present invention, and the modified embodiments should be considered to be included in the scope of protection of the invention claims attached to the present invention.
