FIG. 1 shows the entire lower body exercise device 100 according to an embodiment of the present invention, and FIGS. 2 and 3 schematically show the operating state of the lower body exercise device 100 according to an embodiment of the present invention. 4 and 5 show the pedestal 170 according to an embodiment of the present invention, Figure 6 shows the operating state of the pedestal 170 according to an embodiment of the present invention, and Figures 7 and 8 show the pedestal 170 according to an embodiment of the present invention. Shows the operating state of the lower body exercise device 100 according to an embodiment.

The lower body exercise device 100 according to an embodiment of the present invention may include a first support element 110, a second support element 130, a connection element 150, and a stand 170.

The first support element 110 is disposed on a support surface such as the floor and can support the user's body. For example, the first support element 110 may be disposed on a bed 200, more specifically, on a first frame 210, which will be described later. The first support element 110 is a flat, thin plate that can support a part of the user's body, for example, the lower body.

The shape and size of the first support element 110 are not particularly limited, and may be a rectangle smaller than the width of the bed 200. Additionally, the first support element 110 may be made of a slippery material with a low coefficient of friction so that the user's body can slide smoothly. In one embodiment, the first support element 110 may have at least an upper surface made of a plastic material with a low coefficient of friction, such as polyethylene or polytetrafluoroethylene.

Although not shown in the drawings, the first support element 110 may further include a friction member to prevent slipping when placed on the floor or bed 200, etc. For example, one or more friction members are disposed on the lower surface of the first support element 110, so that the user's body slides on the upper surface of the first support element 110, but the first support element 110 itself is on the support surface. You can prevent it from slipping on the table.

The friction member may be made of a material with a high coefficient of friction, such as non-woven fabric, PDMS, or rubber. One or more friction members may be arranged along the longitudinal direction of the first support element 110. In one embodiment, the friction member may be detached from the upper surface of the bed 200. For example, the sliding member may be a detachable member such as Velcro.

In one embodiment, one or more guides 111 may be disposed on the first support element 110. For example, as shown in FIGS. 1 to 3, two guides 111 may be disposed on the upper surface of the first support element 110, spaced apart from each other. A pair of guides 111 may be arranged parallel to each other at both edges in the width direction of the first support element 110.

In one embodiment, the guide 111 may have an inclined surface on one side. As shown in Figure 1, the guide 111 has a predetermined inclination on the inside of the width direction of the first support element 110, that is, on the surface facing the user's lower body while the user is lying down on the lower body exercise device 100. It can be provided with a slope. Accordingly, the guide 111 can maintain the user's lower body from external rotation to prevent strain on the user's lower body during exercise.

The guide 111 may have a triangular pyramid shape with an inclined surface on the inside. Additionally, the guide 111 may be arranged to include the longitudinal center of the first support element 110.

The second support element 130 may be arranged to be spaced apart from the first support element 110 . The second support element 130, like the first support element 110, is disposed on a support surface such as the floor and can support the user's body. For example, the second support element 130 may be disposed on the bed 200, more specifically, on the second frame 230, which will be described later. The second support element 130 is a flat, thin plate that can support a part of the user's body, for example, the upper body.

In one embodiment, the shape and material of the second support element 130 are not particularly limited and may be the same as the first support element 110. For example, the second support element 130 may also be rectangular, smaller than the width of the couch 200 . Additionally, the first support element 110 may be made of a slippery material with a low coefficient of friction, for example, a plastic material with a low coefficient of friction, so that the user's body can slide smoothly.

In one embodiment, the second support element 130 may not include the friction member. That is, the friction member may be disposed only on the lower surface of the first support element 110 and not on the lower surface of the second support element 130. Accordingly, when the user bends or extends his or her knees, the upper body may slide together with the second support element 130.

The connection element 150 is disposed between the first support element 110 and the second support element 130 and connects the first support element 110 and the second support element 130. The connection element 150 may change length as the first support element 110 and/or the second support element 130 moves. Accordingly, the user can perform a lower body exercise by bending or straightening the knee while supporting the body on the first support element 110 and the second support element 130 without moving relative to them.

Additionally, the connection element 150 has a variable length and/or shape, so that it can correspond to various shapes and sizes of the bed 200. For example, when the gap between the first frame 210 and the second frame 230 of the bed 200 is long, the length of the connecting element 150 can be increased, and conversely, the first frame 210 and the second frame If the distance between (230) is short, the length of the connecting element (150) can be shortened. In another embodiment, the connecting element 150 has a fixed length, and the user may slide and exercise on the first support element 110 and the second support element 130. Hereinafter, for convenience of explanation, the description will focus on the case where the length of the connection element 150 is variable.

More specifically, as shown in FIG. 2 , when the user lies on the first support element 110 and the second support element 130 and extends his or her knees, the connection element 150 may have a maximum length L1. Then, as shown in FIG. 3, when the user bends the knee, the second support element 130 approaches the first support element 110 and the connection element 150 is deformed in the longitudinal direction, reducing the length to L2. .

In one embodiment, the connecting element 150 may be made of a deformable fabric material. For example, as shown in Figures 2 and 3, the connection element 150 is folded or unfolded depending on the force applied in the longitudinal direction or the displacement between the first support element 110 and the second support element 130 to increase the length. It can change.

Alternatively, the connecting element 150 may be an elastic member. For example, connection element 150 may be one or more springs disposed between first support element 110 and second support element 130 . Connecting elements 150 may be leaf springs or coil springs. Accordingly, the user can bend or straighten the knee and move the second support element 130 toward or away from the first support element 110 to compress or extend the connection element 150. Through this, the restoring force of the connection element 150 can increase the intensity of exercise.

Alternatively, the connection element 150 may be a wrinkled member that has a plurality of irregularities formed on at least the upper and lower surfaces and can be unfolded or folded in the longitudinal direction. That is, the connection element 150 may have a shape like a corrugated pipe, and thus its length may change depending on the displacement between the first support element 110 and the second support element 130.

The stand 170 may be disposed on one side of the first support element 110 to support the user's feet. For example, as shown in FIG. 1 , the pedestal 170 may be disposed at an end of the first support element 110 . The user can exercise while supporting one surface of the stand 170 with his or her feet.

In one embodiment, the stand 170 is supported on the support panel 250 of the bed 200 to prevent the lower body exercise device 10 from being separated from the bed 200 when the user exercises.

In one embodiment, the stand 170 may include a body 171, a length adjustment member 173, and an anti-slip member 175.

The body 171 supports the user's feet and may be supported on the support panel 250 of the bed 200. In one embodiment, the body 171 may have a rectangular parallelepiped shape with a wide surface that contacts the user's feet.

One or more length adjustment members 173 may be disposed on one surface of the body 171. As shown in Figure 4, one or more length adjustment members 173 may be disposed on the surface opposite to the surface supporting the user's foot. The length adjustment member 173 may be disposed on one side of the body 171 and extend toward one side, for example, toward the support panel 250. For example, the length adjustment member 173 may operate in a screw-like manner. More specifically, when the length adjustment member 173 is rotated clockwise or counterclockwise, it can move in the thickness direction of the body 171. Accordingly, the distance between the length adjustment member 173 and the support panel 250 can be adjusted.

The number and location of the length adjustment members 173 are not particularly limited. One or two or more length adjustment members 173 may be arranged, and a plurality of length adjustment members 173 may be arranged at equal or different intervals.

In one embodiment, a plurality of length adjustment members 173 may be disposed, and an adjustment plate (not shown) may be disposed at an end of the length adjustment member 173. For example, the length adjustment member 173 is disposed on one side of the body 171, and the adjustment plate having a cross-sectional area greater than the sum of the cross-sectional areas of the entire length adjustment member 173 is disposed at an end of the length adjustment member 173. It can be. The pedestal 170 can be firmly supported on the support panel 250 through the adjustment plate having such a large area.

The anti-slip member 175 may be disposed on the other surface of the body 171. For example, as shown in FIG. 5, the anti-slip member 175 may be disposed on the side facing the user's foot, that is, on the side opposite to the side where the length adjustment member 173 is disposed. The anti-slip member 175 may be uneven formed on the body 171. For example, the anti-slip member 175 may protrude or be concavely recessed from one surface of the body 171. This allows users to prevent their feet from slipping during exercise.

The anti-slip member 175 may be formed straight along the longitudinal or height direction of the body 171 or may have a wave shape.

In one embodiment, the stand 170 may include a footrest 177a, a first link 177b, a second link 177c, and a third link 177d, as shown in FIG. 6.

The footrest 177a may be placed on one side of the body 171, more specifically, on the side facing the user's feet. The footrest (177a) may be rotatably disposed on the body (171). When the stand 170 includes a footrest, the user's feet may contact the footrest 177a rather than the body 171. Additionally, the anti-slip member 175 may be formed on the footrest 177a. The footrest (177a) can be rotated by the second link (177c) and third link (177d), which will be described later.

The first link 177b extends from one side of the footrest 177a to support the floor, etc. For example, the first link 177b is a rod-shaped member extending from both sides of the footrest 177a, and may contact a support surface such as the floor or the upper surface of the bed 200. Additionally, the first link 177b can maintain contact in parallel with the support surface even if the footrest 177a rotates.

The second link 177c rotates integrally with the footrest 177a and may extend diagonally toward the second support element 130. For example, as shown in FIG. 6, a pair of second links 177c are connected to both sides of the footrest 177a, and may be disposed between the footrest 177a and the first link 177b. When the second link 177c rotates, the footrest 177a may also rotate in the same manner.

The third link 177d is disposed between a pair of second links 177c and can be used by the user as a handle during exercise. As shown in FIG. 6, the user can adjust the angle of the footrest 177a by holding the third link 177d and pulling it inward or pushing it outward.

Through this configuration, the user can adjust the angle of the ankle in contact with the pedestal 170 by adjusting the angle of the footrest 177a. Accordingly, the user can control the exercise area and exercise intensity.

In one embodiment, the stand 170 may further include an angle fixing member (not shown) that fixes the angle of the footrest 177a. For example, when the user pulls the third link 177d and tilts the footrest 177a, the angle adjustment member can maintain the angle of the tilted footrest 177a. For example, the angle adjustment member may be inserted from both sides of the fixed first link 177b or the body 171 to fix the footrest 177a and the second link 177c.

In one embodiment, the user may exercise while holding the third link 177d while exercising the lower body with assistance from the strength of the upper body.

In another embodiment, the footrest (177a) may operate separately from the first link (177b), the second link (177c), and the third link (177d). For example, the footrest (177a) includes a separate rotation member (not shown) that rotates it, and the first link (177b), the second link (177c), and the third link (177d) are held by the user's hand and the upper body It can be used to support . To this end, the rotating member may include a handle and a position fixing member.

In one embodiment, it may further include an adjustment member (not shown) that gradually adjusts the rotation angle of the footrest (177a). The rotation member is disposed at a connection portion between the body 171 and the footrest 177a, and can adjust the rotation angle of the footrest 177a in predetermined angle units. For example, the adjustment member may adjust the angle between the footrest 177a and the body 171 in 5-degree, 10-degree, or 15-degree increments. In this case, the position fixing member may be integrally included in the adjustment member. You can.
