Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for combination furniture, and more particularly to a connector for connecting combination furniture in vertical and horizontal directions.

Various types of connectors are known for connecting furniture, such as bookshelves, in a fixed direction. A simple connecting member has not yet been provided.

However, large joints are generally used as vertical joints for stacked furniture, but this is mainly for the purpose of fixing the stacking position and preventing the furniture placed on it from sliding horizontally. It's just something that happened.

The present invention aims to provide a furniture connector that allows furniture to be stacked or combined in a vertical and horizontal direction, that is, furniture can be combined and connected in three dimensions if necessary.

The present invention will be described below with reference to drawings showing embodiments thereof.

As shown in FIG. 1, the furniture connector consists of a connecting member 1 and connecting pins 2, 3.

The connecting member 1 is a bottomed cylinder with one end open and the other end closed, and a notched groove 5 is provided in the side portion 4 of the connecting member 1 .

The connecting member 1 is not limited to the cylindrical body shown in the drawings,
It does not matter what shape it is, as long as it can fit into the bottom button and connection hole provided on the top of the furniture.

The notch groove 5 is located near the center in the longitudinal direction from the open end of the connecting member 1.
They are provided by cutting out the thick part, and as shown in FIG. 3, they are provided at two locations with an opening angle of 90 degrees from the center.

The peripheral wall of the inner cavity of this bottomed cylinder forms a peripheral surface 8 that slopes inward from the open end toward the bottom of the other end.

That is, the wall thickness of the side portion of this bottomed cylindrical body gradually increases from the opening at one end to the bottom at the other end.

The other end of this bottomed cylinder, that is, the bottom, is provided with a protrusion that protrudes from the center position into the inner cavity, and the protrusion has a screw hole 6.
However, in the past, holes 7, 7 were drilled through the bottom of the left and right sides with this as the point of symmetry.

As shown in FIG. 4, the connecting pin 2 includes a body portion 9 having a certain length, a shaft portion integrally formed at both ends of the body portion 9, and a shaft portion connected to the body portion 9. It consists of an engaging head 11.

The engaging head 11 has an inclined surface 12 that comes into close contact with the circumferential surface 8 .

The shaft portions may be made of synthetic rubber or resin material so as to be able to expand and contract slightly as necessary.Also, as shown in FIG. It may be replaced by a connecting pin 2a which is connected by a coil spring 13 and whose outer periphery is covered with a cover material 15.

Although the above-mentioned connecting pins 2 and 2a are shown in the drawings as having mating heads at both ends, they are not necessarily limited to this.

In other words, as long as an engaging head is formed at least at the → end, there is no problem as long as the other end can be connected to the side furniture to be connected by some means. .

As shown in FIG. 6, the connecting pin 3 has a connecting head 11 having an inclined surface 12 at one end of a shaft connected to the body 9, and a flat plate body 15 at the other end, which are integrally formed. This is what happens.

As shown in FIG. 7, the proposed connector is constructed by first assembling the connecting member 1 and fitting the two parts into the holes 17 drilled at the four corners of the bottom of the furniture 16, and then inserting the two parts into the holes 17 made in the four corners of the bottom of the furniture 16. screws 18, 18
is screwed in to fix the connecting member 1 to the furniture 16.

In this case, the cutout groove 5 needs to be fixed so as to face two adjacent sides of the furniture 16.

On the other hand, as shown in FIG. 8, holes 20 opposite to the holes 17 are provided at the four corners of the upper surface of the furniture 19 on which the furniture 16 is to be placed.
and a semicircular groove 20 extending from it to two adjacent sides.
a, 20a are formed, and the connecting pin 2 is arranged in the hole 20 and the semicircular groove 20a.

In this case, the engaging head 11 of the connecting pin 2 is placed in the hole 20, and the other end is connected to the adjacent side furniture, or the engaging head 11 of the connecting pin 2 is placed in the hole 22 provided in the side furniture. The engaging head 11 at the other end is placed in advance.

In this state, the cutout grooves 5 of the connectors provided on the lower surface of the furniture 16 are fitted and connected so as to straddle the shaft portions 9 of the connecting pins 2 disposed in the holes 20.

On the other hand, when furniture 21.23 to be installed adjacent to these furniture 16.19 is to be installed in a row, the furniture 21.23 is installed in the same manner as described above.

When installing panel furniture 24 in a row, furniture 16.1
9, connect the connecting pin 3 to the panel furniture 24 in advance.
are placed in the required positions, and as described above, the furniture 16.
19, the engaging head 11 of the connecting pin 3 is engaged with and connected to the connecting member 1.

Therefore, as shown in FIG. 9, when the furniture 16, 19 and the furniture 21, 23 are fixed respectively, the engaging head 11 of the connecting pin 2 moves to the upper end of the notch groove 5 of the connecting member 1 and is fixed.

That is, the inclined surface 12 of the connecting pin 2 is connected to the peripheral surface 8 of the connecting member 1.
When the shaft portion 9 reaches the thicker portion, the shaft portion 9 is pulled toward the engaging head 11 side.

Therefore, the furniture 19 and 21 and the furniture 23 and 16 can be closely connected without creating any gaps.

Then, from inside the furniture 19 and 21 located below the furniture 16 and 23, the connecting member 1 is held with the screw 26.
into the screw holes 6 to connect the upper and lower pieces of furniture, respectively.

Furniture 16, 19, 21 and 23 are thus tightly connected together.

According to the present invention described above, the structure is extremely simple, easy to mold and manufacture, and easy to install.Furthermore, furniture can be closely connected vertically and horizontally, and there are no gaps between pieces of furniture. It is possible to connect the combination furniture with an extremely good appearance.
