Description

  The present invention relates to a sitting chair, and more particularly, to a sitting chair placed under a buttocks in order to facilitate sitting for a long period of time, for example, in legal matters.

Japanese Utility Model Registration No. 3114639 discloses the use of an upright seat integrally formed in a predetermined shape with a synthetic resin such as foamed polyethylene (hereinafter referred to as “used upright seat use”).
Utility Model Registration No. 31164639

The above-mentioned conventional sitting chair is integrally formed in a predetermined shape, and therefore is bulky and inconvenient to carry and store.

The present invention solves the above-mentioned problems in the above-described conventional sitting use, and provides a sitting use that can be made compact and convenient for storage by being disassembled and folded when not in use. It was made in an attempt.

  In order to solve the above problems, the present invention provides the following sitting chair.

It consists of a base part and a seat part detachably mounted on the base part,
The base part is a square cylinder body that can be folded flat, and the seat part is provided with a locking part that locks to the upper end of the base part on the lower surface (claim 1). .

  According to the present invention, the seat is detachable from the base, and the base is a rectangular tube body that can be folded flat (see FIG. 7). When it is folded flat, it is in a compact state that is convenient to carry and store. That is, the seat part and the base part folded flat in this way can be stored in a handbag, a pocket or the like and carried.

  It is also very easy to assemble a seat chair that has been disassembled as described above.

  In addition, since the seat part has a latching part that latches to the upper end of the base part on the lower surface, when the latching part of the seat part is latched to the upper end of the base part, the seat part is removed from the base part during use. There is no risk of detachment, and the foldable base is stable during use.

  In addition, since the sitting posture according to the present invention preferably supports the weight of the user when in use, the user's foot is not burdened and the foot is not numb.

  The seat using the seat according to the present invention comprises a base 1 and a seat 3 that is detachably mounted on the base 1.

  The base part 1 and the seat part 3 may be formed of any material such as synthetic resin, wood, cardboard, or metal.

  The base 1 is a rectangular cylinder that can be folded flat.

  The pedestal 1 is a rectangular cylinder formed by connecting four flat plates 5 so that they can be bent together.

  In the example shown in FIG. 8, each flat plate 5 is formed of a synthetic resin, and each flat plate 5 is connected so as to be bent via a hinge portion 7a.

  In the example shown in FIG. 9, each flat plate 5 is formed of corrugated cardboard, and each flat plate 5 is foldably connected via a hinge portion 7b.

  Each flat plate 5 may be connected to each other via a hinge. Further, a bottom plate (not shown) may be pivotally attached to the lower end of any flat plate 5.

  The seat portion 3 includes a locking portion 9 that locks to the upper end 1 a of the base portion 1 on the lower surface. The seat portion 3 is preferably formed wider than the base portion 1.

  The locking portion 9 is preferably a convex portion that locks to the inner surface of the opening portion of the upper end 1 a of the base portion 1.

  In the example shown in FIGS. 2 and 4, a pair of parallel protrusion-shaped locking portions 9 a that are locked to upper ends of the inner surfaces of a pair of opposed flat plates 5 are formed on the lower surface of the seat portion 3.

  In the case shown in FIGS. 3 and 5, one trapezoidal locking portion 9 b that is fitted to the upper end of the inner surface of the four flat plates 5 is formed on the lower surface of the seat portion 3.

  A cushion material or the like may be appropriately attached to the upper surface of the seat portion 3.
