Hereinafter, each component will be described in detail with continued reference to FIGS. 1 to 10 .

The body 110 is a component constituting the body of the stepper 100 of the present invention. The body 110 may have a structure or shape that can be placed on the floor. Further, the body 110 may be formed of a plate member as shown in FIG. 1 as an example, or may be formed of a frame member although not shown as another example, and as another example, a plate member and a combination of a frame member. In addition, although not shown, when the body is made of a plate member, reinforcing ribs and the like may be provided on the inner surface of the body.

The first and second guides 120A and 120B are components for guiding the movement of each of the shin receiving units 130 for supporting both sides of the user's shins, respectively. The first and second guide portions 120A and 120B may be provided with left and right intervals on the body 110 . For example, each guide 120 may have a rail shape as shown in FIG. 3 as an example, or may have a groove shape although not shown as another example.

Each shin receiving unit 130 is a component for supporting both shins of the user, respectively. Each of these shank receivers 130 may be moved along each guide 120 in a state engaged with each guide 120 . For example, as shown in FIG. 3 , when the guide part 120 has a rail shape, the shin receiving part 130 may have a through hole 130a for penetrating the guide part 120 . Although not done, if the guide portion has a groove shape, the shin receiving portion may have an insertion protrusion for insertion into the guide portion.

Each of the pressing portions 140 is a component for applying a tension to each of the shin receiving portions 130 while the respective shin receiving portions 130 are moved along the respective guides 120 . For example, each of the pressing parts 140 may be a tension spring 141 as shown in FIGS. 3 and 9 . As shown in FIG. 9 , one end of the tension spring 141 may be provided on the body 110 and the other end of the tension spring 141 to apply a tensile force to the shin receiving portion 130 . can be provided in

The handle unit 150 is a component for the user to hold by hand so that the user does not fall while performing an exercise using the stepper 100 of the present invention. For example, the handle 150 may include a handle support 151 and a handle 152 as shown in FIG. 1 . The handle support 151 may be provided on the body 110 and protrude substantially upward, and the handle 152 may be provided on the upper end of the handle support 151 .

Accordingly, since such components are provided, the shin of the user's left leg and the shin of the right leg are placed on each shin receiving unit 130 , and each shin receiving unit is placed in a state in which the handle unit 150 is held by hand. By alternately pushing 130 along each guide part 120, the knee joint and its lower parts can be directly operated, such as muscle strength exercise or aerobic exercise of a force corresponding to the tensile force of each pressing unit 140. Because it is not a structure used as a body type, it is possible to minimize the strain on the knee joint during strength training or aerobic exercise not only for those who can walk normally, but also for those who have a bad knee joint or have a disability under the knee joint.

Hereinafter, each guide unit 120 will be described in more detail with reference to FIGS. 1 and 3 again.

Each of the guides 120, as shown in FIGS. 1 and 3, may have a gradually downwardly inclined shape from the front end to the rear end of the body 110. Therefore, it is possible to provide the effect of climbing the stairs repeatedly in place through such an inclined shape.

In particular, looking in more detail, each guide unit 120 may have a curved shape of an exponential function graph, as shown in FIGS. 1 and 3 , but may have a downward convex shape. Therefore, it is possible to more easily induce the rotation of the femur with respect to the user's hip joint while performing the movement to climb the stairs using the part above the knee joint, thereby minimizing the strain on the hip joint (Fig. see 10).

Hereinafter, with continued reference to FIGS. 3 to 8 , each shank receiving portion 130 will be described in more detail.

Each of the shank receivers 130 may include a slider 131 , a shin receiver 132 , and a hinge 133 as shown in FIG. 3 . The slider 131 may be engaged with the guide 120 and move along the guide 120, and the shin rest 132 may support the user's shin when the user's shin rests thereon, and a hinge ( 133 may include a shin rest 132 rotatably with respect to the slider 131 . Accordingly, as the shin rest 132 is rotated with respect to the slider 131 with respect to the hinge 133 , the user's degree of freedom of the shin can be increased, so that the shin rest can be placed on the shin rest 132 more comfortably.

Furthermore, as shown in FIG. 4 , the shin rest 132 may have a recessed shape (ie, a concave shape) so that the left and right sides of the shin are caught when the user's shin is placed thereon. Accordingly, through this recessed shape, it is possible to prevent the user's shin from being separated from the shin rest 132 during exercise.

In addition, the hinge 133, as shown in Figure 3, the shin rest 132 may be rotatably provided in a pitch motion (pitch motion). Thus, it is possible to tilt the shin rest 132 downwardly forward, so that while pushing the shin rest 132 with the shin, the shin wedges further towards the front of the shin rest 132 and the shin moves away from the shin rest 132. Separation can be further prevented (see FIG. 10).

In addition, the shin rest 132, as shown in FIG. 5, when viewed from the top to the bottom, the front end of the user's knee joint does not touch the concave portion (E10) of a shape recessed toward the rear end. can Therefore, when the user's shin is placed on the shin rest 132 , the knee joint, which is relatively convex compared to the shin, can be located in the empty space that is the front part entering the concave portion E10 as a boundary, that is, the knee joint is the shin rest. It is possible to prevent the knee joint from being pressed by not touching (132).

In addition, as shown in FIGS. 4 to 7 , the shin support 132 may further include a support band part E20 for selectively supporting the front part or the rear part of the user's knee joint. The support band portion E20 may be provided at the front end of the shin rest 132 . Therefore, when the support band part E20 supports the front part of the knee joint as shown in FIG. 6 , the shin support 132 can be sufficiently pushed forward, so that the exercise effect on the thigh (for example, the strengthening effect of the thigh muscle) ) can be given, and when the support band part E20 supports the back part of the knee joint as shown in FIG. hip-up effect] and the like.

Specifically, the support band portion (E20), as shown in Figure 5, the support band (E21), the band ring (E22), and may include a detachable member (E23). The support band E21 may have one end fixed to an upper end of one side among the front ends of the shin rest 132 . The band ring E22 may be provided at the upper end of the other side of the front end of the shin rest 132 and may penetrate the other end of the support band E21. Removable member (E23) may be provided in the support band, the other end of the support band (E21) passing through the band ring (E22) to be detachably attached to the part of the support band (E21) that does not pass through the band ring (E22) can be fixed. Therefore, in order to support the back of the knee joint, the shin is placed on the shin support 132, and the support band E21 is released or the already released support band is passed through the band loop (E22) to be positioned at the back of the knee joint. to fix the support band E21 with the detachable member E23.

For example, the support band E21 may be made of an elastic material. In addition, the removable member (E23) may be a Velcro (Velcro: also called a "sticker") or the like.

In addition, as shown in FIG. 8 , the support band E21 may have a rounded shape with convex top and bottom ends. Therefore, even if the upper end or lower end of the support band E21 touches the front or rear portion of the knee joint, it is not sharp, so damage to the skin can be prevented.

In addition, the stepper 100 according to an embodiment of the present invention may further include a tension adjusting unit 160 as shown in FIG. 9 . The tension adjusting unit 160 may adjust the tension of the tension spring 141 . Therefore, the user can apply the desired tensile force, so that any person, regardless of age or sex, can perform strength training by adjusting the tension to suit them, and can be shared and used by several people.

For example, the tension adjusting unit 160, as shown in Figure 9, a rack member (rack member) 161, a pinion member (pinion member) 162, a tension roller (tension roller) 163, And it may include a tension fixing pin (164). The rack member 161 may be movably provided on the body 110 , and the pinion member 162 may be rotatably provided on the body 110 , and may be gear-engaged with the rack member 161 . The tension roller 163 may be rotatably provided on the rack member 161, and may adjust the tension of the tension spring 141 by pushing the middle part of the tension spring 141, and the tension fixing pin 164 may be a pinion member ( 162) or the rack member 161 may be fixed to stop the movement.

Therefore, when the user rotates the pinion member 162 forward and reverse through the dial (D10 in FIG. 1) exposed to the outside of the body 110, the rack member 161 meshed with the gear moves up and down, and the tension roller 163 increases the tension. The tensile force of the tension spring 141 may be adjusted by tightening or loosening the spring 141 .

In addition, as shown in FIG. 9 , the stepper 100 according to an embodiment of the present invention may further include a guide roller 170 . The guide roller 170 may be rotatably provided on the body 110 and smoothly guide the tension spring 141 to the path of the guide unit 120 while the tension spring 141 is pulled but returned to its original position. .

On the other hand, the aforementioned handle support 151 may have a length adjustment structure in which the length is adjusted. Therefore, the height of the handle can be adjusted according to the height of the user, so that several people can share and use it regardless of the height.

For example, the handle support unit 151 is a length-adjustable structure, and as shown in FIG. 1 , may include a lower supporter 151a, an upper supporter 151b, and a height fixing pin 151c. The lower support 151a may be provided on the body 110 and may have a plurality of height adjustment holes H10 at intervals in the vertical direction. The upper support 151b may have an upper end provided in the handle 152, and its lower end may be inserted into the lower support 151a as a telescopic structure, and in any one of a plurality of height adjustment holes H10. It may have a corresponding pin hole H20. The height fixing pin 151c may be inserted into any one of the plurality of height adjustment holes H10 through the pin hole H20. Therefore, by inserting the height fixing pin (151c) into the pin hole (H20) and the height adjustment hole (H10) in a state in which the user matches the pin hole (H20) to the one at the desired height among the plurality of height adjustment holes (H10). You can keep the height adjusted.

Furthermore, the handle 150 may further include a forearm support 180 as shown in FIGS. 1 and 10 . The forearm support 180 may be detachably provided on the handle support unit 151 and may support the user's forearm (front arm). Therefore, by raising the user's forearm on the forearm support 180 and supporting the load of the upper body on the forearm support 180 as much as possible, exercise can be performed even if the hand strength is weak.

The handle portion, as shown in FIGS. 1 and 10 , may further include an upper body support that is detachably provided on the handle support and supports the upper body of the user's chest. Therefore, by raising the user's chest portion on the upper body support 190 to support the load of the upper body as much as possible on the upper body support 190, even if the strength of the hand and arm (forearm or upper arm) is weak, the exercise can be performed. Even people who do not have the strength can use it sufficiently.
