Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a chair.
[0002]
[Prior art]
Conventionally, a chair for a study desk or the like has a wheel 28 attached to the outer surface of the side walls 27, 27 of the chair body 26 as shown in FIG.
[0003]
[Problems to be solved by the invention]
However, since the wheels are directly attached to the chair body, it takes a lot of trouble when attaching the wheels. Moreover, when storing in a learning desk, there was a possibility that the wheel hits the learning desk and was difficult to store, and the life of the wheel could be shortened.
[0004]
Then, an object of this invention is to provide the chair which can attach a wheel easily. It is another object of the present invention to provide a chair that can be smoothly stored in a learning desk without the possibility of wheels hitting the learning desk when stored in the learning desk.
[0005]
It is another object of the present invention to provide a chair that can be easily distributed and managed. Another object is to provide a chair with high rigidity and strength.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a chair according to the present invention has a chair body provided with left and right side walls, a seat part, a back part, and a footrest, and a horizontal plane storage shelf arranged close to the floor surface. A chair having a pair of cross beams arranged on the front edge and the rear edge, and a plurality of front and rear vertical beams connecting the cross beams; , a rotatable wheel body in this fixing support shaft around each and rotating the wheel assembly mounted vertically movably to the wheel body, the fixing shaft of the wheels comprising a left-right end of the crossbeam By inserting from the lower surface , the wheel is attached to the four corners of the storage rack, and the storage rack subunit is formed by the wheel and the storage rack , and the storage rack subunit between the left and right side walls of the chair body. And inserting the bolts from the left and right outer sides of the left and right side walls, And screwing the crossbeam of the left and right buried nuts at each end face, Ru der which the storeroom shelf subunits were fixed by fastener consisting of the bolt and the nut to the left and right side walls of said chair body.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
[0008]
1 and 2 show an embodiment of the present invention. The chair includes a chair body 5 including a seat portion 1, a back portion 2, side walls 3 and 3, and a footrest 4, and a horizontal plane storage shelf 6 disposed close to the floor surface G. For example, a school bag (not shown) can be placed on the storage shelf 6.
[0009]
A storage shelf subunit S as shown in FIGS. 3 to 5 is fixed to the chair body 5 (see FIG. 1 and FIG. 2) with fixing tools 17 such as bolts and nuts. The storage rack subunit S is formed by attaching wheels 7 (see FIG. 1) to the four corners of the storage rack 6.
[0010]
Specifically, the storage rack 6 has a pair of front and rear horizontal beams 8 and 8 and a plurality of vertical beams 9 that connect the horizontal beams 8 and 8 to the left end 8a and the right end 8b of the horizontal beam 8, Wheels 7 and 7 are attached.
[0011]
As shown in FIG. 6, the wheel 7 includes a vertical fixing support shaft 10, a wheel body 11 that is rotatable about the fixing support shaft 10, and a rotating wheel body that is attached to the wheel body 11 so as to be movable up and down. And twelve. The fixing support shaft 10 is configured to be attached to the cross beam 8 (see FIGS. 1, 3, and 4) by insertion. With this configuration, the fixing support shaft 10 can be easily attached to the cross beam 8 by insertion. Also, the number of bolts required for assembly can be reduced.
[0012]
The rotating wheel body 12 is connected to the wheel body 11 via the sliding member 13 and the elastic body 14. When a person sitting on the chair, as shown by two-dot chain lines, rotating the wheel member 12 is raised relative to the wheel body 11, ing a non-rotatable state.
[0013]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists an effect described below.
[0014]
After attaching the wheel 7 to the storage rack 6, the storage rack subunit S can be fixed to the chair body 5, and the mounting work of the wheel 7 is easy. In addition, when stored in the learning desk, there is no possibility that the wheels 7 interfere with the learning desk and get in the way, and it can be smoothly stored in the learning desk and has a long life. Furthermore, since it is an assembly type, distribution and inventory management can be easily performed.
[0015]
In addition, rigidity and strength are large.
Further, the chair can be easily moved not only in the front-rear direction but also in the left-right direction and the oblique direction. Further, the wheel 7 can be rotated when the chair is not used, and the wheel 7 can be disabled when the chair is used.
