Description

[Detailed Description of the Invention] The present invention relates to an improvement of a chair with a table installed on the floor of a civic hall, a lecture room, a theater, etc.

The purpose of this invention is to increase the usable area of the table board pivoted to the front seat that each person can freely use in a row-by-row layout where people sit from the front with the front part of the seat as a passageway, and to ensure stable use. This makes it possible to secure the condition of the building and to arrange it with high accommodating efficiency per unit floor area.

Conventionally, foldable table boards have been attached to the backs of rows of chairs fixed on the floor of civic halls, conference rooms, etc., so that each person can freely use them as desks.

However, most of these table boards have a small usable area, and are unstable in the unfolded state of use, making it extremely difficult to write on the table board.

In addition, the space between the front and back of tables, chairs, and passageways has increased, resulting in a decline in accommodation efficiency per unit area.

The best way to increase this efficiency is to make the chair smaller.
Small chairs have the problem of not being able to withstand sitting for long periods of time.

The present invention provides a chair with a table that solves the above-mentioned conventional problems.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a pair of left and right legs, which are fixed to a flat floor or a step floor.

A fixed or flip-up seat 2 and a back seat 3 are attached to the legs 1, and a pair of left and right armrests 4 are also provided.

Therefore, in the present invention, a vertically long guide groove 5 is provided as a guide part on the back of the leg 1, and engaging metal fittings 8 fixed to both ends of the table plate 7 are slidably inserted into the guide groove 5.

As is clear from FIGS. 2 to 4, this engaging fitting 8 has a hook shape, and has projections 8a protruding from both sides thereof.

Further, an end cap 6 is fitted to the upper end of the leg 1, and this end cap 6 has a hole 6a into which a claw of an engagement fitting 8 is inserted and an engagement member 6b.

The table plate 7 attached to the guide groove 5 of the leg 1 so as to be slidable and deployable has a length up to one side opposite to the one side on which the engagement fitting 8 is attached to the armrest 4 of the rear seat.
The table board 7 has a dimension length that can be supported on a rack, and therefore the effective area of the table board 7 is expanded accordingly.

Reference numeral 10 denotes a stopper for latching the table board 7 when it is folded, and is attached to a cross member 9 fixed between the upper ends of the legs 1 so as to be openable and closable.

Since the present invention has the structure as described above, when the table plate 7 is not used, the engaging fitting 8 can be slid onto the lower end of the guide groove 5, as is clear from the view of the rear seat in Figure 1. position, and place the stopper 1 with the surface of the table board 7 facing the back of the leg 1.
0 stops the hanging.

Therefore, the passage in front of the seat is effectively secured. Note that when the table board 7 is not in use, the back surface is exposed and the front surface is hidden and protected, so the user can always use a clean table surface.

Further, when the table plate 7 is used, when the latching by the stopper fitting 10 is removed, the engaging fitting 8 will be in a state where it can freely slide in the guide groove 5.

Therefore, by sliding the engagement tool 8 above the guide groove 5, the table plate 7 is inevitably expanded in the horizontal direction, and the engagement tool 8 engages with the engagement member 6b, and the table plate 7
One side of the frame is supported on the armrest 4.

According to the above invention, the table attached to the back of the leg has a hook-shaped engagement fitting with projections protruding from both sides, which is slidably inserted into a vertically long guide groove on the back of the leg. Because of this, it is possible to smoothly rotate the folding state parallel to the legs and the horizontal state substantially perpendicular to the legs using the pull-out stop protrusion as a fulcrum, and the locking fittings are provided at the upper ends of the legs. When used while engaged with the mating member, it is supported on the armrest, so it can be used stably in a substantially horizontal direction without moving in the front-rear, left-right directions, and the table area can also be increased.

Furthermore, by removing the end cap at the upper end of the leg to which the table's engagement fittings are engaged, the table can be easily removed from the leg when not needed, and has the advantage of being quickly assembled. .
