Abstract

PROBLEM TO BE SOLVED: To easily use a table as necessary even in a small place and maintain the stability of even a lightweight chair. SOLUTION: In this chair having a seat plate 2 fixed on legs 1, a pair of right and left guide rails 11 for supporting a table under the seat plate 2 are provided so that the table 10 is longitudinally slidably supported between a use position in which it projects backward and a storage position in which it is stored under the seat plate 2. When used as necessary, the table 10 is pulled out backward. When not used, the table 10 is stored under the seat plate 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair in which a seat plate is fixed on a leg, and is suitable mainly for a small and lightweight pipe chair which is mainly provided in a main hall of a temple or the like when reading or preaching. About chairs.

[0002]

2. Description of the Related Art When a large number of followers gather in the main hall or auditorium of a temple, it is convenient to arrange chairs and tables to place books or rosaries, but space is limited. Many are cramped.

[0003] In order to solve such a problem, for example, in a seat of a vehicle such as a train, a folding table is provided on the back of a backrest of a front seat. Something folds in.

[0004]

In the case where a folding table as described above is provided, a strong and rigid backrest is required, which is not suitable for a light and small pipe chair or the like. For example, the following problem occurs.

(1) When applied to a lightweight and small main hall chair, it is difficult to attach a table with a small backrest, and the stability of the chair is deteriorated.

(2) In a state where the table is folded and stored, the back surface of the table can be seen, so that the back surface of the table must be finished with a decorative plate or the like so that the cost increases.

(3) The table width at the time of use is fixed, and the table width, that is, the front-back width cannot be adjusted.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to easily set a table on the rear side without losing stability even in a lightweight and small chair such as a chair for a main hall and a chair without a backrest. It is to provide a chair that can do.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a chair having a seat plate fixed on a leg, a table support mechanism provided below the seat plate, and the table support mechanism. Thus, the table is supported so as to be slidable in the front-rear direction over a use position protruding rearward and a storage position where the table is stored below the seat plate.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a chair to which the present invention is applied. The chair includes a pipe leg 1 having an overall U-shape when viewed from the side. A pair of L-shaped backrest pipes 5 is provided on the left and right sides, and a backrest 6 is fixed to the pipes 5. The leg 1 has a front-rear two-part structure with the mating surface H as a boundary, and the joint core 4 is inserted into the connection portion of the leg 1 and connected by a plurality of rivets 7. A table 10 that can be pulled out rearward is provided below the seat plate 2 of the chair.

FIG. 2 is a plan view with the seat plate 2 removed, and the front half of the leg 1 is integrally formed by bending right and left via a front end cross portion 9a, and the rear half of the leg 1 is also formed. The left and right sides are integrally bent and formed via the rear end cross portion 9b. As a table support mechanism, a pair of left and right guide rails 11 is fixed to the inner surface of each pipe 5 located below the seat plate 2. Are connected by stoppers 12 and 13, respectively. The left and right ends of the table 10 are supported by the pair of guide rails 11 so as to be slidable in the front-rear direction.

FIG. 3 is an exploded perspective view of the table 10.
The table 10 includes a rectangular frame 15 and a plate 16, and the outer peripheral edge of the plate 16 is fitted into the inner peripheral groove 15 a of the frame 15.

FIG. 4 is an enlarged cross-sectional view taken along the line IV-IV of FIG. 2. The left and right guide rails 11 are formed to have a U-shaped cross section and are arranged so as to face each other.
Is connected to the inner surface of the pipe 5 by a rivet 7 that connects Left and right frame members 15 of the table 10 are supported by the guide rails 11 so as to be slidable in the front-rear direction.
8 are formed, and the right and left ribs 18 regulate the table 10 so as not to swing right and left.

The rear stopper 13 is notched so that the vertical wall portions at the left and right ends do not contact the left and right frames 15 of the seat plate 10, and the horizontal wall portions at the left and right ends are guided by rivets 17. 11 is fixed to the lower surface. The position of the rivet 17 is between the rib 18 and the vertical wall of the guide rail, so that the seat plate 10 does not come into contact with the rivet 17 during sliding.

The operation will be described. FIG. 5 shows a state in which the table 10 is pulled out to the rear use position. The front frame 15 of the table 10 is locked by the rear stopper 13 so that the table 10 is prevented from dropping backward. I have. FIG. 5 shows a state where the table 10 is pulled out to the maximum, but the drawing width is arbitrary, and the table 10 can be pulled out and used by a necessary amount.

FIG. 6 shows a state in which the table 10 is stored under the seat plate 2 in the storage position. The rear frame 15 of the table 10 is locked by the rear stopper 13 so as to move forward. Overslide is prevented.

When the table 10 is slid, the left and right frames 15 are guided by the ribs 18 as shown in FIG. 4, so that they do not come into contact with the rivet 7 for the leg 1 or the rivet 17 for fixing the stopper, so that the frame is smooth. A simple sliding operation can be maintained.

It is also possible to adjust the dimensions so that the front frame 15 of the table 10 comes into contact with the front stopper 12 in the storage position shown in FIG.

[0019]

[Other Embodiments] (1) FIG. 7 shows an example in which the present invention is applied to a chair without a backrest. The basic structure, that is, the structure of the pair of left and right guide rails 11, the table 10, and the stoppers 12 and 13 in FIG. 4 is the same as that of the chair having the backrest, and the difference is that in FIG. The pipe 5 is eliminated, and the guide rail 11 is fixed to the inner surface of the leg 1 by the rivet 7.

(2) The present invention is not limited to chairs for main halls, but can be applied to various pipe chairs and the like.

[0021]

As described above, according to the present invention, (1) a table support mechanism such as the guide rail 11 is provided below the seat plate 2, and the table 10 is provided by the table support mechanism.
Is slidably supported in the front-rear direction over a use position that projects rearward and a storage position that is stored below the seat plate 2, so that a conventional folding table can be compared with a chair provided with a backrest. Even if it is applied to a light and small pipe chair, it is possible to maintain sufficient stability without shaking.

(2) In the storage position, the table 10 is
, It is not necessary to mount the back surface of the table with good appearance compared to a foldable table, and the cost can be reduced.

(3) Since the table 10 is provided slidably below the seat plate 2, it can be sufficiently applied to a chair without a backrest, and the applicable range is wide.

(4) Since the table 10 is slidable in the front-rear direction, the draw-out amount can be freely adjusted according to the size of the object to be placed or the size of the space between the front seat and the user.

(5) Of course, by providing the table 10 which can be pulled out backward,
Even if a table is not separately prepared, the table can be easily pulled out and used when needed, and can be stored out of the way when not needed.
