Description

  The present invention relates to a cushion structure, and more particularly to a cushion structure that can be used as an abdominal muscle base.

Examples of conventional abdominal muscles include those shown in Patent Documents 5 and 6 below. This has a structure in which a belt or the like for fixing the legs is provided on a base on which the legs and buttocks are placed. Such a dedicated abdominal pedestal has a problem in that it is a hindrance when not in use and takes a large space when stored.
In order to solve such a problem, Patent Documents 1 to 3 listed below provide a rod-like footrest means for fixing a leg to a seat portion of a seat so as to be housed. Patent Document 4 below discloses a cushion mat that can be folded and provided with a footrest means that can be stored. Since these can be used as a sitting chair or a sofa when not used as an abdominal muscle table, they have the advantage that they are not troubled by the storage location.

However, sitting chairs are good in a Japanese-style room, but it is not appropriate to put them in a Western-style room with a sofa. In addition, the cushion mat used as a sofa is large because it is used as a sofa. By placing the cushion mat, an ordinary sofa cannot be placed, and the design as a sofa is restricted.
In view of such a problem, an object of the present invention is to provide an abdominal muscle table that does not get in the way when placed in a Western-style room or a Japanese-style room when not in use.

In order to solve the above problems, the present invention has the following configuration.
The invention according to claim 1 is a cushion main body made of a convex body on which a bent leg is placed, a leg fixing portion made of a rod parallel to the longitudinal direction of the cushion main body, and the leg fixing portion being attached to the cushion. An abdominal muscle assisting cushion having a connecting lid made of a rod or a plate that is fixed and fixed to the leg fixing portion substantially perpendicularly to the side surface of the main body, and the connecting lid is attached to the cushion body. It is formed to expand and contract.
The invention according to claim 2 is the abdominal muscle assist cushion, wherein the cushion body is provided with a recess having a size and a shape in which the leg fixing portion is accommodated in a state in which the connecting lid is contracted. is there.

From the above configuration, the present invention has the following effects.
According to the first aspect of the present invention, when the abdominal muscle exercise is performed, a leg bent on the cushion body is placed so that the leg fixing portion is on the shin side, and the leg fixing portion in a state in which the connection lid is extended is used. The leg can be fixed by pressing the front of the body and abdominal muscles can be exercised. And when you don't do abdominal exercises, shrinking the ligatures will gather the leg fixing part on the cushion body side, and the cushion body can be formed with a cushion that is large enough to bend a bent leg. Even if it is placed on the sofa or the floor, it doesn't cause any discomfort and does not get in the way, regardless of whether it is a Western-style room or a Japanese-style room.
In the invention according to claim 2, since the leg fixing part fits in the recess provided in the cushion body in the state where the connecting air is shrunk, the leg fixing part is gathered as a cushion, and when the abdominal muscle exercise is not performed, it is possible to enter the room without further obstruction You can leave it.

(A) is a perspective view of the abdominal muscle auxiliary cushion in a state where the leg fixing portion is extended, and (b) is a perspective view of the abdominal muscle auxiliary cushion in a state where the leg fixing portion is accommodated. (A) is a longitudinal cross-sectional view of the abdominal muscle auxiliary cushion in a state where the leg fixing part is housed, and (b) is a vertical cross-sectional view of the abdominal muscle auxiliary cushion in a state where the leg fixing part is extended.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1A is a perspective view of the abdominal muscle auxiliary cushion X according to this embodiment. The abdominal muscle auxiliary cushion X includes a cushion main body 10, a leg fixing portion 20, and a connection fixing portion 30.
The cushion body 10 is formed of a convex body whose cross section cut in the longitudinal direction is a substantially regular triangle with rounded corners, and is formed by wrapping a foamed synthetic resin such as urethane in a shape such as cloth or leather. ing. On one inclined surface of the cushion body 10, a recess 11 having a size and shape that can accommodate a leg fixing portion 20 described later is provided along the longitudinal direction. In addition, the coupling fixing portion 30 is accommodated inside the cushion body 10, and a hole through which a coupling lid described later of the coupling fixing portion 30 protrudes is provided at the center position of the recess 11.

  The leg fixing portion 20 is a rod-shaped body having a D-shaped cross section, and a foamed synthetic resin such as urethane is disposed around a pipe or rod-shaped core made of iron or a hard synthetic resin, and further, a cloth or leather is disposed around the periphery. It is formed by wrapping with a sheet. As shown in FIG. 1B, the leg fixing portion 20 is fitted into the recess 11 of the cushion body 10 so that the slope of the cushion body 10 provided with the recess 11 becomes flat. The size is fixed.

  The connection fixing part 30 is a part for connecting and fixing the leg fixing part 20 to the cushion body 10. FIG. 2A shows a longitudinal sectional view of the abdominal muscle auxiliary cushion X in the state of FIG. 1B, and FIG. 2B shows a longitudinal sectional view of the abdominal muscle auxiliary cushion X in the state of FIG. The connection fixing part 30 is formed of a round bar formed integrally with the core material inside the leg fixing part 20, and holds the connection cover 31 protruding from the center hole of the recess 11 of the cushion body 10 and the connection cover 31 so as to be slidable. A sleeve 32 made of a cylindrical body, a holding plate 33 made of a plate body built in the vicinity of the bottom surface of the cushion main body 10, and a support bar 34 made of a rod body that supports and fixes the sleeve 32 to the holding plate 33. A disc 31 a is secured to the base end side of the connecting lid 31 to prevent it from coming off. In addition, a space is provided in the cushion body 10 at a position where the connecting lid 31, the sleeve 32, the holding plate 33, the support bar 34 is accommodated, and a moving range of the connecting lid disk 31 a. With such a configuration, the connection fixing portion 30 can hold and fix the connection lid 31 to the cushion body 10 so as to be extendable and contractible.

Next, a method of using the abdominal muscle auxiliary cushion X having such a configuration will be described. Normally, when not used as an abdominal muscle base, the leg fixing portion 20 is placed in the recess 11 of the cushion body 10 by shrinking the connecting lid 31 as shown in FIGS. 1 (b) and 2 (a). And used as a cushion made of a triangular prism. And when using as an abdominal muscle stand, first, as shown to Fig.1 (a) and FIG.2 (b), it is set as the state which pulled out the leg fixing | fixed part 20 and extended the connection dry 31. FIG. Thereafter, the bent leg L as shown by the imaginary line in FIG. 2B is placed on the convex shape of the cushion body, and the leg is fixed so that the front side of the shin is in contact with the back surface of the leg fixing part 20. And do abdominal exercises.
As described above, when the abdominal muscle auxiliary cushion X according to the present embodiment is not used as an abdominal muscle base, the leg fixing portion 20 is accommodated to form a triangular prism cushion. In use, the leg fixing part can be pulled out and used as an abdominal muscle stand.

  In the above-described embodiment, the cushion body 10 has a substantially triangular ridge having a cross-sectional shape. However, since it is sufficient to support a bent leg, the cross-sectional shape of the ridge is deformed into a semicircle or a trapezoid. May be.
