The base portion 2 and the main body portion 4 are made of wood such as cedar or rubber tree, for example. The convex member 3 is made of a smooth plastic resin such as polypropylene. Hereinafter, the longitudinal direction of the main body 4 is referred to as an X-axis direction, a direction orthogonal to the X-axis in the horizontal plane is referred to as a Y-axis direction, and a direction orthogonal to the XY plane is referred to as a Z-axis direction.

The base portion 2 is a rectangular plate-shaped member installed on the floor surface F (FIG. 6). On the upper surface 2a side, which is the first surface of the base portion 2, a concave portion (base portion side concave portion) 5 having a size corresponding to the convex member 3 is formed. By inserting the lower side of the convex member 3 into the concave portion 5, the convex member 3 is attached to the base portion 2.

In FIG. 3A, the base portion 2 is formed with a plurality of (here, two) holes 6 penetrating from the lower surface 2b of the base portion 2 to the bottom surface 5a of the recess 5. A fastening member 7 (FIG. 3 (b)) such as a screw used for fixing the convex member 3 to the base portion 2 is screwed into the hole portion 6.

In FIGS. 1 to 3, the convex member 3 is formed into an arc shape (semicircular shape) when viewed from the front by cutting a columnar member from a direction orthogonal to a smooth surface. FIG. 4 is a bottom view of the convex member 3 as viewed from below. In FIGS. 3 and 4, the convex member 3 includes a first wall portion 8 and a second wall portion 9 having a region extending in the in-plane direction. The first wall portion 8 and the second wall portion 9 face each other with a predetermined interval.

The first wall portion 8 and the second wall portion 9 are connected to each other via a curved surface portion 10 having a curved surface shape. Each of the first wall portion 8, the second wall portion 9, and the curved surface portion 10 is made of a plastic resin having a smooth surface.

The lower surface 3a side (bottom side) of the convex member 3, which is the side inserted into the concave portion 5 of the base portion 2, is open. That is, the convex member 3 has an internal space 11 (hollow portion) surrounded by the first wall portion 8, the second wall portion 9, and the curved surface portion 10.

A first thick portion 12 and a second thick portion 13 are provided on both sides of the lower surface 3a of the convex member 3 at positions that partition both sides of the internal space. In the present embodiment, the first thick portion 12 and the second thick portion 13 are formed at both ends of the curved surface portion 10, but are formed on the first wall portion 8 or the second wall portion 9. It may be joined to them, or it may be joined to them. When the convex member 3 is inserted to the deepest position with respect to the recess 5 of the base portion 2, the first thick portion 12 and the second thick portion 13 come into contact with the bottom surface 5a of the recess 5 (FIG. 3 (FIG. 3). b)).

In FIG. 3A, holes 14 and 15 are formed in the first thick portion 12 and the second thick portion 13, respectively. One end of the holes 14 and 15 is open from the lower surface 3a of the convex member 3, and the other end is bottomed. In a state where the first thick portion 12 and the second thick portion 13 are in contact with the bottom surface 5a of the recess 5, the hole portion 6 formed in the base portion 2 and the first thick portion 12 and the second thick portion 12 and the second. The holes 14 and 15 formed in the thick portions 13 of the above are communicated with each other. From this state, the convex member 3 is firmly fixed to the base portion 2 by screwing the fastening member 7 into the holes 6, 14 (15) from the lower surface 2b side of the base portion 2. That is, the fastening member 7 is screwed into the first thick portion 12 and the second thick portion 13 via the base portion 2.

In the internal space 11 of the convex member 3, a plurality of plate members 16 are provided in the vertical direction at predetermined intervals. One end of the plate member 16 in the longitudinal direction is joined to the curved surface portion 10, and the other end of the plate member 16 is the lower end of the first wall portion 8 and the second wall portion 9 (in other words, the lower surface 3a of the convex member 3). Located at the same level as. In FIG. 4, both ends of the plate member 16 in the width direction are joined to the first wall portion 8 and the second wall portion 9. The plurality of plate members 16 function as reinforcing portions for reinforcing the convex member 3, and are erected on the first wall portion 8 and the second wall portion 9. Further, the plurality of plate members 16 are located at positions sandwiched between the first thick portion 12 and the second thick portion 13. The number of thick portions formed on the convex member 3 may be one.

The main body 4 is a rotating body that rotates on the base 2 over a predetermined range. For example, by cutting a columnar member from a direction orthogonal to a smooth surface, an arc shape (semicircle) is viewed from the front. It is shaped into a circle). As a result, the cut surface of the main body 4 is a smooth surface 4a, and the arc portion 4b is formed along the circumferential direction excluding the smooth surface 4a of the main body 4.

In FIG. 2A, the main body portion 4 has a concave portion (main body portion side concave portion) 17 formed over a predetermined range by partially removing the arc portion 4b (curved surface). Specifically, the concave portion 17 is formed by partially removing the top portion T of the arc portion 4b (curved surface) along the circumferential direction from the starting point. The inner wall 17a of the main body 4 forming the recess 17 is made "coarse" by, for example, rough surface processing.

The concave portion 17 has a size capable of accommodating a portion of the convex member 3 exposed from the base portion 2. In other words, most of the curved surface portion 10 is covered with the inner wall 17a forming the concave portion 17. In FIG. 2D, when the convex member 3 mounted on the base portion 2 is fitted (accommodated) in the concave portion 17 of the main body portion 4, the upper surface of the curved surface portion 10 of the convex member 3 and the concave portion of the main body portion 4 are accommodated. A clearance (play allowance) having a predetermined width is generated between the inner wall 17a and the inner wall 17a forming the 17.

As shown in FIG. 5, the length dimension s1 in the width direction of the concave portion 17 is set to be substantially the same as or slightly larger than the length dimension s2 in the width direction of the convex member 3. Further, the length dimension s3 in the longitudinal direction of the recess 17 is set to be substantially the same as or slightly larger than the length dimension s4 in the longitudinal direction of the convex member 3. Therefore, in a state where the main body portion 4 is fitted to the convex member 3 via the concave portion 17, the movement of the main body portion 4 in the horizontal plane direction (XY direction shown in FIG. 1) is restricted.

The main body portion 4 is rotatable over a predetermined range along the arc portion (curved surface) 4b with respect to the base portion 2 and the convex member 3 in a state of being fitted to the convex member 3 via the concave portion 17. It is supported (arrow a shown in FIG. 2D). The surfaces of the first wall portion 8, the second wall portion 9, and the curved surface portion 10 are convex portion-side contact surfaces that come into contact with the concave portion 17 (inner wall 17a). Further, the inner wall 17a forming the concave portion 17 is a concave portion side contact surface that contacts the convex member 3.

The smooth surface 4a of the main body 4 is a mounting portion on which both feet L1 and L2 (FIG. 6) of the user are placed. A non-slip member such as a rubber sheet may be provided at a position on the smooth surface 4a where both feet L1 and L2 of the user come into contact with each other, or a plurality of grooves may be formed on the smooth surface.

The exercise device 1 in the present embodiment is configured as described above. Next, an example of using the exercise device 1 will be described with reference to FIG. First, as shown in FIG. 6, the user places the exercise device 1 on the floor surface F. The basic posture of the exercise device 1 before the start of jigging is the position where the top portion T of the arc portion 4b of the main body portion 4 (FIG. 2 (a) is closest to the base portion 2, in other words, the smooth surface 4a is horizontal. (Fig. 2 (d)).

The user then places each of one foot L1 and the other foot L2 on both sides of the smooth surface 4a (placement portion). Next, as shown in FIG. 6A, when the user moves one foot L1 downward from the heel side, the main body portion 4 maintains the fit between the concave portion 17 and the convex member 3 in the direction of arrow b. As it rotates, the other foot L2 moves upward.

Next, as shown in FIG. 6 (b), when the user moves the other foot L2 downward from the heel side, the main body 4 maintains the fit between the concave portion 17 and the convex member 3 in the direction of arrow c. As it rotates, one foot L1 moves upward. Then, when the user alternately moves one foot L1 and the other foot L2 up and down in small steps (jiggling), the main body 4 rotates by reciprocating (arrow b → arrow c → arrow b → arrow c ...・).

When the main body portion 4 is rotated, the convex members 3 come into contact with the edge portions E1 and E2 of the concave portion 17, respectively, so that the movement of the main body portion 4 in the longitudinal direction (X-axis direction) is restricted. Further, the movement of the main body 4 in the width direction (Y-axis direction) is also restricted by the contact of the main body 4 with the convex member 3 as described above. That is, according to the exercise device 1 in the present embodiment, the movement of the main body 4 in the XY direction (inward the horizontal plane) during jigging is restricted.

Further, when the user exercises by jigging using the exercise equipment 1, the convex member 3 and the inner wall 17a forming the concave portion 17 of the main body portion 4 come into contact with each other. For example, since the first wall portion 8 and the second wall portion 9 constituting the convex member 3 have a region extending in the in-plane direction, a case may occur in which the convex member 3 is rubbed while in surface contact with the inner wall 17a.

In the conventional exercise equipment, since the main body 4 and the member corresponding to the convex member 3 are made of wood whose surfaces are "coarse" with each other, the "rubbing sound" when these members come into contact (surface contact) is large. From the viewpoint of sound leakage, it was necessary to consider the surroundings when using the exercise equipment 1. On the other hand, according to the exercise device 1 in the present embodiment, the convex portion side contact surface in which the convex member 3 contacts the main body portion 4 (inner wall 17a forming the concave portion 17) is made of a smooth plastic resin, and therefore, “rubbing”. "Sound" can be reduced.

The exercise device 1 in the present invention is not limited to the present embodiment, and the design can be changed within a range that does not deviate from the gist of the present invention. For example, a sheet member made of a smooth plastic resin may be attached to the surface of the convex member 3 (first wall portion 8, second wall portion 9, curved surface portion 10). In such a case, the surface of the sheet member becomes the convex side contact surface. Further, the inner wall 17a (concave side contact surface) may be formed of a smooth plastic resin, or a sheet member made of plastic resin may be attached to the inner wall 17a (in such a case, the convex member 3 may be made of wood). .. Further, both the convex side contact surface and the concave side contact surface may be formed of a smooth plastic resin.

That is, the exercise device 1 in the present embodiment has an arc portion 4b, a main body portion 4 that rotates over a predetermined range by the user alternately moving both feet up and down, and an arc portion 4b of the main body portion 4. The concave portion 17 formed in the concave portion 17 and the convex member 3 (convex portion) fitted to the concave portion 17 are provided. The convex side contact surface where the member 3 contacts the concave portion 17 is made of plastic resin. Further, in the convex member 3 incorporated in the exercise device 1 in the present embodiment, the user places both feet L1 and L2 on the main body portion 4 rotatably provided on the base portion 2, and the convex member 3 is in this state. It is a convex member 3 incorporated in an exercise device 1 that rotates the main body 4 over a predetermined range by alternately moving both feet L1 and L2 up and down, and the convex member 3 is attached to the base portion 2. The convex portion side contact surface that is fitted into the concave portion 17 formed in the main body portion 4 and in which the convex member 3 contacts the concave portion 17 is made of plastic resin. Further, in the method of attaching the convex member 3 to the base portion 2 in the present embodiment, the user places both feet L1 and L2 on the main body portion 4 fitted to the convex member 3 mounted on the base portion 2. It is a method of attaching the convex member 3 to the base portion 2 in the exercise device 1 in which the main body portion 4 is rotated over a predetermined range by alternately moving the legs L1 and L2 up and down in the state, and the convex member 3 is a plastic. The main body is made of resin, the base portion 2 is formed with a concave portion 5 to which the convex member 3 is mounted, and the convex member 3 is formed with a thick portion (first thick portion 12, second thick portion 12). With the thick portion 13) provided and the convex member 3 mounted on the base portion 2, the base portion 2 and the thick portion are fastened by the fastening member 7.

According to the present invention, it is possible to reduce the rubbing noise generated when the user exercises by jigging, and to eliminate the lack of exercise in various facilities (including outdoor facilities) including private houses, offices, and facilities for the elderly. Especially useful as a tool to do.
