Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a chair.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, some chairs for study desks have wheels 28 attached to the outer surfaces of side walls 27, 27 of a chair body 26.

[0003]

However, since the wheels are directly attached to the chair body, it takes a lot of time and effort to attach the wheels. Also, when storing it in the study desk,
The wheels hit the learning desk and were difficult to store, which could shorten the life of the wheels.

Therefore, an object of the present invention is to provide a chair to which wheels can be easily attached. Also,
Another object of the present invention is to provide a chair that can be smoothly stored in the learning desk without the risk of the wheels hitting the learning desk when stored in the learning desk.

Another object of the present invention is to provide a chair whose distribution and inventory can be easily managed. Also,
Another purpose is to provide a chair with high rigidity and strength.

[0006]

In order to achieve the above-mentioned object, the chair according to the present invention is a chair having a horizontal plane storage shelf arranged close to the floor surface. Wheels are attached to the corners to form a shelving shelving subunit, and the shelving shelving subunit is fixed to the chair body by a fastener.

Further, the storage rack has a pair of front and rear lateral girders and a plurality of longitudinal girders connecting the lateral girders, and wheels are attached to the left and right ends of the lateral girders. Further, the wheel includes a fixing support shaft, a wheel body rotatable around the fixing support shaft, and a rotating wheel body attached to the wheel body so as to be movable up and down.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the drawings showing the embodiments.

1 and 2 show an embodiment of the present invention. This chair comprises a seat 1, a back 2, side walls 3, 3 and
A chair main body 5 having a footrest 4 is provided, and a horizontal plane storage shelf 6 arranged close to the floor surface G is provided. For example, a school bag (not shown) can be placed on the article storage shelf 6.

A storage rack sub-unit S as shown in FIGS. 3 to 5 is fixed to the chair body 5 (see FIGS. 1 and 2) by fixing members 17 ... The storage rack sub-unit S is formed by attaching wheels 7 ... (See FIG. 1) to the four corners of the storage rack 6.

More specifically, the storage rack 6 has a pair of front and rear lateral girders 8 and 8 and a plurality of longitudinal girders 9 connecting the lateral girders 8 and the left end 8a and the right end of the lateral girder 8. Wheels 7, 7 are attached to 8b.

As shown in FIG. 6, the wheel 7 has a vertical fixing support shaft 10, a wheel body 11 rotatable around the fixing support shaft 10, and a wheel body 11 which is vertically movable. And a rotating wheel body 12. The fixing support shaft 10 is configured to be attached to the cross beam 8 (see FIGS. 1, 3, and 4) by being inserted. With this configuration, the fixing support shaft 10 can be easily attached to the cross beam 8 by inserting it. Also,
The number of bolts required for assembly is small.

The rotating wheel body 12 includes a sliding member 13 and an elastic body 14.
Is connected to the wheel body 11 via. When a person sits on a chair, as shown by the chain double-dashed line,
The wheel 12 rises with respect to the wheel body 11 and is in a non-rotatable state.

It should be noted that the present invention is capable of design change,
For example, the storage shelf 6 has a pair of left and right vertical girders 9 and 9 and a plurality of horizontal girders 8 that connect the vertical girders 9 and 9, and the front end and the rear end (not shown) of the vertical girder 9, The wheels 7 and 7 may be additionally provided.

[0015]

Since the present invention is constructed as described above,
The following effects are achieved.

(According to the first aspect) After the wheels 7 are attached to the storage rack 6, the storage rack subunit S can be fixed to the chair body 5, and the work of mounting the wheels 7 is easy.
In addition, there is no risk that the wheels 7 interfere with the learning desk when it is stored in the learning desk, the wheel 7 can be smoothly stored in the learning desk, and the life is long. Furthermore, since it is an assembly type, distribution / inventory management can be performed easily.

The rigidity and strength are high (according to claim 2). The chair can be easily moved not only in the front-back direction but also in the left-right direction and the diagonal direction (according to claim 3). Further, the wheels 7 can be rotated when the chair is not used, and the wheels 7 cannot be rotated when the chair is used.
