Description

[Detailed Description of the Invention] The present invention relates to a connection fitting for assembling furniture such as reception sets and beds.

Traditionally, furniture such as reception sets and beds are assembled in factories and then transported to consumers or retail stores. There were drawbacks such as high costs for management.

In order to improve this, a knock-down type connecting fitting was devised, but when this knock-down type connecting fitting is used, for example, the seat of a sofa to which this connecting fitting is attached has a knock-down type connecting fitting and an armrest. When connected to the connector, the resistance force during the connection caused the screws, nails, etc. attaching the connector to come up, resulting in an incomplete connection.

Therefore, the present invention was devised for the purpose of making it possible to securely attach the connecting metal to a furniture frame, etc., and to further reduce the loosening of the connecting part caused by the conventional knock-down type.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. In the drawings, A indicates a connecting metal fitting that is attached to the main body of furniture such as the seat of a sofa, and this connecting metal fitting A is a guiding metal fitting A1. It is used in combination with a threaded rod body B which is cut out from the locking plate A2 and the crown mounting plate A3 and is attached to a subordinate body E of furniture such as the armrest of a sofa.

The guide fitting A1 includes a cylindrical guide portion 1, and chamfers 5 are provided at an appropriate number of locations on the outer peripheral surface 4 in the longitudinal direction of the guide portion 1.

A male screw part 3 into which a nut C is screwed is provided on the outer circumferential surface 4 of the guide part 1 from one end of the guide part 1, and the other end of the guide part 1 is provided with a hole in the center that matches the inner diameter of the guide part 1. A flange portion 2 is provided which extends perpendicularly to the central axis of the external force.

The locking plate A2 has a circular hole 7 bored in the center and radial cuts from the circular hole 7 to provide a plurality of locking claw pieces 6, and the locking claw pieces 6 are slightly bent in the same direction. It is bent and composed.

The crown attachment plate A3 is bent into a cross-section of the crown attachment plate main body 8, which is bored centering around a hole 10 having approximately the same size as the entire root portion, at which the locking claw piece 6 is attached. The crown attachment piece 9 is abraded onto the outer periphery of the crown attachment plate main body 8 to be integrated.

Then, the locking plate A2 that is in contact with the flange portion 2 is held in between, and the crown attachment plate 9 is bent and attached to the flange portion 2 to be fixed.

The threaded rod body B is provided with a locking part 11 on one side in which locking flanges 13 that are locked with locking claw pieces 6 are provided at appropriate intervals, and on the other side a threaded part that can be screwed onto the furniture body E. 12 will be provided.

In particular, as the threaded rod body B, one may be used in which the locking part 11 is threaded with a fine male thread with a small pitch as the locking flange 13, and the threaded part 12 is threaded with a coarse male thread with a large pitch, The locking portion 11 and the threaded portion 12 may be threaded with male threads having the same pitch.

Furthermore, the chamfered portion 5 may or may not be provided.

The shape of the flange portion 2 and the shape of the crown attachment plate body 8 to match the shape are both square or triangular.

The present invention is constructed as described above, and an example of its use will be described below.The guide part 1 of the connecting fitting A is inserted from the inside into the hole D1 bored in the main body of a sofa seat, etc. , screw together with nut C from the outside.

Furthermore, a threaded rod body B is attached to the furniture body E such as the armrest of a sofa.
To install the nut C, insert the threaded rod body B into the guide part 1 from the direction shown in FIG.
The locking flange 1'3 is press-fitted and connected to the locking claw piece 6 so as to be locked therein.

Therefore, the locking plate A2 is provided with a plurality of locking claw pieces 6, and the locking claw pieces 6 are slightly bent in the same direction to give an appropriate inclination angle to the threaded rod body. B can be easily press-fitted without requiring a large force for press-fitting, and once it is press-fitted, the locking flange 13 of the locking part 11 is locked by the locking claw piece 6, so the screw Rod B will not deviate.

The guide fitting A1 is formed by being provided with a cylindrical guide part 1, having a male screw part 3 provided from one end of the guide part 1 on the outer circumferential surface 4 of this guide part 1, and having a flange part 2 provided at the other end.
Can be securely fixed to the main body of furniture such as the seat of a sofa,
There is no possibility of an uncertain fixed state due to the action of external forces.

Moreover, since the threaded rod body B is inserted into the guide part 1,
The threaded rod body B can be guided reliably, the threaded rod body B itself can be prevented from moving in the vertical and horizontal directions, and the connecting portion can be reinforced.

The crown mounting plate A3 is a crown mounting plate in which a hole 10 with a locking claw piece 6 and a hole 10 of approximately the same size as the entire root portion is bored in the center of the crown mounting plate main body 8, and the crown mounting plate is bent into an L-shape in cross section. Since the piece 9 extends around the outer periphery of the crown attachment plate main body 8, it prevents the entire locking plate A2 from lifting up when the threaded rod body B is press-fitted, and prevents the flange portion 2 from lifting up.
The locking plate A2 can be brought into close contact with the locking plate A2.

The threaded rod body B is provided with a locking part 11 having flanges 13 provided at appropriate intervals on one side, and a threaded part 1 that can be screwed on the other side.
2 is provided, so it can be easily attached to the furniture body E such as the armrest of a sofa, and the connection between the main body of the furniture such as the seat of the sofa and the furniture body E. It can be done in close contact with each other.

In particular, when the threaded rod body B is formed by threading fine male threads with a small pitch on the locking part 11 as the locking flange part 13, the connection between the main body of the furniture and the furniture body E is avoided. If the locking part 11 and the threaded part 12 are threaded with male threads having the same pitch, the threaded rod body B itself can be manufactured easily.

Further, by providing a chamfered portion 5 on the outer circumferential surface 4 of the guide portion 1 and providing a hole D1 that matches the cross-sectional shape of the guide portion 1 on the main body of the furniture, rotation of the connecting metal concrete A itself can be prevented. .

Since both the shape of the flange portion 2 and the shape of the crown plate main body 8 matching the shape are appropriately square, the connecting metal concrete A is attached to the main body of the furniture using the nut C. When installing, the flange portion 2 can be reliably clamped using a spanner or the like.

゛As explained above, according to the present invention, the connecting metal can be easily attached to the main body of furniture such as the seat of a sofa.
Moreover, it can be installed securely, and since it is a knock-down type, it can be easily connected to a threaded rod body.
The furniture main body and the furniture body can be easily connected, and the furniture main body and the furniture body can be separated.
Transportation and inventory management costs can be reduced,
In addition, since the structure is simple, it can be provided at low cost, which is extremely useful in practice.
