Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chair connection device that allows a number of identical chairs to be connected laterally.

[Conventional technology]

Conventionally, the structure was such that both chairs could be connected to the left and right through a side table board,
Seen in Publication No. 175753.

[Problem that the invention attempts to solve]

However, such a structure has the problem that even if it is locked with the locking metal fitting, looseness is likely to occur between the chair side and the side table plate, resulting in an unstable connection structure. ing.

[Means for solving problems]

The present invention solves such problems and enables a highly stable connection.Therefore, the front and rear edges of the long rectangular connecting plate are provided with one part of both chairs to be connected. Two recessed notches that can be fitted into the front and rear side support legs are formed side by side, and the side seat frames of both chairs, to which the sides of the connecting plates can be joined, are formed so that when rotated, the bottom side of the side of the connecting plates can be joined. The clamping plate is movable up and down and rotatable, and is installed at each intermediate portion.

[Effect]

Therefore, the front and rear support legs of the two chairs to be connected are fitted into the front and rear recesses of the connecting plate, respectively.
When the clamping plates installed on the side seat frames of both chairs are lowered and rotated, and are pressed against the lower surfaces of both sides of the connecting plate, both sides of the connecting plate will be pressed against the seat frames of both chairs and will not come off. This allows the two chairs to be connected by the connecting plate without causing play.

〔Example〕

Next, the embodiment shown in the drawings will be described. A
indicates a chair, with four support legs 2 erected on the front, back, left and right sides, a seat frame 4 installed on the left and right, a seat body 6 above the both seat frames 4a installed on the front and back, and a seat 6 installed above the rear. A back body 7 is provided, and it is made of wood and constructed in the same manner as the conventional structure.

1 is a connecting plate, which is formed into a rectangular shape, and
When connecting, the connecting plate 1 is formed wide so that both sides can be joined to the lower surfaces of the seat frames 4, 4 of both chairs A.
On the front and rear edges of both chairs A, two recessed notches 3 that can fit into the front and rear support legs 2, 2 on one side of the chair A are formed in parallel. The stand can also be constructed by integrally forming it from a synthetic resin material.

A mounting bracket 8 is fixed to the inner surface of the side seat frame 4 of each chair A at the center in the front and rear direction with screws 9, 9,
A support rod 10 extending upward from the clamping plate 5 consisting of a long plate part 5a and a short plate part 5b is inserted into the mounting bracket 8 so as to be vertically movable and rotatable, and extends upward from the mounting bracket 8. A compression spring 11 is fitted in the upper part of the support rod 10 to press the clamping plate 5 upward.

Therefore, by bringing both chairs A closer together laterally,
As shown by the imaginary lines in FIG. 4, the connecting plate 1 is tilted and the double concave notches 3 on the rear edge side are fitted into the rear supporting legs 2, 2 of both chairs A, and from this state, the connecting plate 1 is moved upward. When raised to a horizontal position, the front supporting legs 2, 2 of both chairs A will fit into the double recessed notches 3 on the front edge side, and then the front support legs 2, 2 of both chairs A will fit into the lower inner sides of the seat frames 4, 4 of both chairs A. The clamping plates 5 are changed from the state shown by the imaginary line in FIG. 5 to the state shown by the solid line,
When the compression spring 11 is stretched and pushed down, and the long plate portion 5a is held and rotated by 90 degrees in the direction of arrow A, the short plate portion 5b will face the lower side of the connecting plate 1, When you release your hand from the clamping plate 5, the clamping plate 5 is pressed upward by the compression spring 11, and both sides of the connecting plate 1 can be clamped and supported from below so that they come into pressure contact with the lower surface of the seat frame 4, thereby eliminating play. This means that both chairs A can be connected in a locked state to prevent this from occurring.

Further, by performing the reverse operation, the connection plate 1 can be removed and the connection can be released.

[Effect of idea]

In this way, the present invention has two parts on the front and rear edges of the connecting plate 1.
When the front and rear supporting legs 2 of both chairs A are respectively fitted into the respective recessed notches 3 formed respectively, and the holding plates 5 on both seat frame 4 sides are pushed down and rotated,
Both sides of the connecting plate 1 can be pressed and locked against the lower surface side of the seat frame 4 by both clamping plates 5, and both chairs A can be connected stably without any play, and the connecting plate 1 can be locked. It has the advantage that it can be easily installed and removed, and that it can be conveniently implemented with a simple structure.
