DETAILED DESCRIPTION OF THE INVENTION

(22) Hereinafter, detailed descriptions related to well-known functions or configurations will be ruled out in order not to unnecessarily obscure subject matters of the present invention. Since the present invention may, however, be embodied in different forms and various modifications and variations can be made in the present invention, specific embodiments will be described in detail with reference to the accompanying drawings. However, this does not limit the present invention within the specific embodiments and it should be understood that the present invention covers all the modifications, equivalents, and replacements within the idea and technical scope of the present invention. In the following description, the technical terms are used only for explaining a specific example (or embodiment) while not limiting the present disclosure. In the present invention, the meaning of include or comprise specifies a property, a fixed number, a step, an operation, an element, a component, or a combination thereof but does not exclude other properties, fixed numbers, steps, operations, elements, components, combinations thereof.

(23) Hereinafter, an embodiment of a quads and gluteus exercise of the present invention to achieve the above-described objects will be described in detail with reference to the accompanying drawings.

(24) In order to resolve the second problem of the technical object, as illustrated in FIGS. 3 to 6 (KR10-2021-0040066), the exercise device according to the present invention may include: a frame 1; a handle 7 connected to the frame 1; a seat 4 connected to the frame 1; a pivot axis 11 connected to the frame 1 and disposed in parallel to the hip joint of the user; an arm 10 connected to the pivot axis 11; and a shock absorber 12 connected to the arm 10. The exercise device may allow a user to perform an exercise similar to a natural movement of a body of the user by pivoting a portion of a body connected to the arm 10 and simultaneously performing a compression movement, and may be flexibly extended in length and automatically restored based on a different in body length caused by folding and unfolding of the hip joint and knees of the user by installing the shock absorber 12.

(25) The shock absorber 12 may apply a resistive force to the inside thereof by pressing, hydraulic pressure, and spring elasticity according to the typical technology. The shock absorber 12 may be contracted and then extended or extended and then contracted on the contrary. Preferably, the shock absorber 12 may be integrated with the arm 10 or arranged linearly with the arm when viewed on a sagittal plane.

(26) In addition, a muscle resistance according to the pivot exercise may increase by connecting a resistance body to the pivot axis 11. When an embodiment of the present invention is used as an indoor bicycle, a motion range of the bicycle may be extended, and an exercise effect may increase.

(27) Also, an exercise device of the related art in which a pivot axis of an arm is disposed parallel to the hip joint or the knees causes inconvenience because the arm of the exercise device, which contacts a body according to a pivot angle of the hip joint or the knees, has a constant length. For example, since a distance from the pivot axis to the pedal decreases when legs are raised, and the distance increases when the legs are lowered, the fixed length of the arm causes inconvenience, and the knees are over-bent or over-extended to cause side effects. However, in the present invention, the distance may be flexibly extended and then automatically restored according to the difference of the body length when folded and unfolded by installing the shock absorber 12.

(28) In order to resolve the second problem of the technical object, as illustrated in FIGS. 3 to 6 (KR 10-2021-0046163), the exercise device according to the present invention may include: a frame 1; a handle 7 connected to the frame; a seat 4 connected to the frame; a pivot axis 11 connected to the frame 1; an arm 10 pivotably connected to the pivot axis; a pipe 12a having a straight line shape and disposed linearly to the arm; and a bar 12b having a straight line shape and disposed inside the pipe to vertically move. Here, as the pedal 5 is connected to the bar 12b, the user may perform a movement of raising the legs toward the chest and then pivoting the legs around the hip joint and simultaneously pulling and compressing the legs in a state in which the user put the legs on the pedal 5. Through this, as the rotation exercise and the compression exercise are simultaneously performed, the exercise similar to the natural movement of the body may be performed, and when the user sits on the seat 4 to raise the legs toward the chest and then lower the legs and pivot the legs backward through the linear movement of the bar in the pipe, the length of the arm may be flexibly extended and then automatically restored according to the substantial variation in length of the legs contacting the arm caused by the pivoting exercise of the hip joint.

(29) According to a typical technology through a pipe 12a and the bar 12b disposed in the pipe, the resistive force may decrease by the inner pneumatic pressure or hydraulic pressure or the spring elasticity, and the pipe 12a and the bar 12b may be contracted and then extended or extended and then contracted on the contrary. Also, a muscle resistance according to the pivot exercise may increase by connecting a resistance body to the pivot axis.

(30) When an embodiment of the present invention is used as an indoor bicycle, a motion range of the bicycle may be extended, and an exercise effect may increase.

(31) In order to resolve the third problem of the technical object, as illustrated in FIG. 6 (KR 10-2021-0046163), the exercise device according to the present invention may include: a second pipe 22 connected in parallel to the pipe; a second bar 21 disposed in the second pipe; and a second bar fixing body 20 disposed on the bar, so that the pedal 5 does not rotate around the bar as the second bar 21 linearly moves to the outside from the inside of the second pipe 22 when the bar linearly moves to the outside form the inside of the pipe. Thus, when the user performs a compression exercise from a start position of putting the legs on the pedal 5 and pulling the legs, the pedal 5 may linearly moves instead of rotating. In addition, as illustrated in FIG. 20 (KR 10-2021-0046813), the pedal may not rotate around the pipe by selectively providing a guide rail to the pipe 31a and a roller 32a to the bar and selectively forming a groove in the bar or cutting one surface of the bar and providing a projection on the pipe.

(32) In order to resolve the fourth problem of the technical object, as illustrated in FIGS. 3 to 20, the exercise device according to the present invention may include a gear device allowing left and right arms of the exercise device to organically rotate by using the gear and the roller and be automatically restored from an exercise ending position to the start pose, and to move on the axis parallel to the ground or rotate around the axis perpendicular to the ground, and as the gear device is attached to an existing bicycle to use a resistive body of the existing bicycle, the technology of the exercise device according to the related art may be realized, and the existing bicycle may be recycled.
