Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a connecting device for connecting and fixing the top plates of multiple tables when they are used side by side or in combination. .

[Conventional technology]

When using multiple tables side by side or combining multiple tables to form one wide table, there may be gaps between the tops of adjacent corner tables, or there may be a step on the surface of the tops. , or when adjacent tables shift back and forth, it is not only inconvenient to use, but also looks bad.

[Problem to be solved by the invention] This invention enables the top plates of adjacent tables to be easily and securely connected to each other when arranging multiple tables or combining them to form one wide table. , it is possible to connect the top plates of adjacent tables without creating a step or gap between them, and without shifting the position of the tables, and it is also possible to easily separate the connected top plates from each other. It is an object of the present invention to provide a connecting device for a table top plate.

[Means to solve the problem]

In order to achieve the above object, the present invention provides downward recesses at opposing positions on the lower surface of the top plate of each table to be connected, and connecting ports that open from both recesses to the end surface of the top plate and communicate with each other. formed,
In a recess provided in one of the top plates, a connecting metal fitting that can rotate in the horizontal direction and project its tip from the connecting port to the end surface of the top plate is pivoted, and an engagement port is provided at the protruding end;
A locking metal fitting with an upwardly directed engagement claw at its tip is pivotally mounted in the recess provided on the bottom surface of the other top plate so as to be able to rotate up and down at the middle part, and the rear end of the locking metal fitting is attached to an elastic member. A connecting device was constructed by elastically biasing the connector downward.

[Effect]

The table top connection device according to the present invention is constructed as described above, and when connecting both table tops,
The connecting fitting provided in the recess of one of the top plates is rotated to the side to protrude from the connection opening portion to the end surface of the top plate side,
By inserting the protrusion into the recess through the connecting port provided on the other top plate, the engaging claw of the locking metal provided in the recess elastically connects to the engaging hole provided at the tip of the connecting metal. The top plates of both tables are connected and fixed together. Furthermore, when separating the connected top plates, simply by pressing the rear end of the locking metal piece upward, the engagement claw at the tip will disengage from the engagement opening of the connection metal piece, and the connecting metal piece and the locking metal piece will be separated. When the engagement is released, both top plates can be easily separated. Moreover, when not connecting, the connecting metal fittings may be rotated inward to the top plate recess.

〔Example〕

Hereinafter, the present invention will be explained in more detail with reference to embodiments shown in the drawings.

In the present invention, for example, as shown in FIG.
This is a connecting device for connecting and fixing the top plates 1 and 2 to each other.

A slit 9 is provided that communicates with the connection port 10 penetrating from the location 3 to the side end surface 1b of the top plate 1, and by rotating the connection fitting 7 laterally, the tip thereof is connected to the connection port 10.
In addition to being able to protrude from the top plate side end surface 1b,
A locking opening 11 is provided in the protrusion. Further, on the casing 6 of the other top plate 2, there is a mounting plate 12, 12, which is cut and raised on the bottom plate 6a of the casing 6, or by welding other parts, etc., and is provided with an upward engagement plate at the tip. The middle part of a locking metal fitting 14 provided with a claw 13 is fixed by a shaft 15, and the rear end of the locking metal fitting 14 and the bottom plate 6a of the casing 6 are connected to each other by a shaft 15.
A spring 16 is interposed between the engaging claw 13 and the engaging claw 13 to elastically bias it upward, and on the side surface of the frame body 6 in front of the engaging claw 13, a hole is provided that penetrates from the recess 4 to the end surface 2b on the top plate side. A slit 17 communicating with the connecting port 18 is formed.

In order to connect the top plates 1 and 2 of both tables A and B using the connecting device configured as described above, the connecting fitting 7 provided in the casing 5 of one of the top plates 1 is connected to the casing 5. The connecting fitting 7 is rotated laterally from the bottom opening by an operation piece 20 appropriately provided on the connecting fitting 7 so as to protrude laterally from the top plate side end surface 1b, and the protruding portion is connected to the slit 18 of the other top plate 2 and the housing. When inserted into the housing 6 through the connecting port 17 of
The upward engaging claw 13 of the locking metal fitting 14 is elastically engaged with the engagement opening 11 by the compression spring 16 by climbing over the upward engaging claw 13 at the tip of the locking metal fitting 14 provided on the top plate 1, 2. are connected and fixed. and,
To release this connection, the rear end of the locking metal fitting 16 is pressed upward against the elastic force of the spring 16, so that the engaging claw 13 at the tip of the locking metal fitting 14 engages with the tip of the connecting metal fitting 7. When the two top plates 1 and 2 are separated from each other by being disengaged from the abutment 11 and the two top plates 1 and 2 are separated, the connecting fitting 7 is pulled out from the through hole 18 of the top plate 2 and the two top plates 1 and 2 are separated. Ru. Then, the connecting fitting 7
If the top plate is rotated into the recess 3 of the top plate 1 except when connecting the top plate, the top plate side end 1b
It doesn't stick out from the outside and get in the way.

In the above embodiment, the connecting fitting 7 is provided with an operating piece 20 to facilitate rotational operation of the connecting fitting 7, and the connecting fitting 7 is provided on the bottom surface 5a of the casing 5 on the top plate side end surface. A protrusion 21 is provided to prevent the connecting fitting 7 from rotating inward of the housing 5 when it is projected from the housing 5, and the connecting fitting 7 shown by the imaginary line in FIG. By providing a protrusion 22 to prevent the connecting metal fitting 7 from rotating toward the top plate side end 1b when the connecting metal fitting 7 is rotated and stored, the connecting metal fitting 7 can be used when connecting the top plates. 7 is fixed in a state protruding from the top plate side end 1b, the connection operation can be performed reliably, and the connection fitting 7 can be prevented from inadvertently protruding to the side of the top plate 1 when not connected. .

Further, the connection port 10 or 18 provided in the top plate 1 or 2 for inserting the connection fitting 7 is provided with a size that allows the connection fitting 7 of the connection device to pass through, as shown in FIG. As shown in the figure, the connection port 10,
