Description

[Detailed Description of the Invention] The present invention relates to an assembly device for wood products such as furniture.

It is made by dividing thick furniture such as chests of drawers and bookshelves.

A method of assembling this furniture at a predetermined location in a room has been used in the past, but if the furniture is very large, it takes time to assemble it, and it also needs to be firmly fixed.

Traditionally, in such cases, the furniture was nailed together, but this method requires considerable skill to avoid unduly damaging the furniture.

The present invention aims to provide a device that can be easily and firmly assembled with one touch without requiring any skill.

The present invention will be explained below with reference to the drawings.

Figure 1 is a perspective view of the present invention, where 1 is a threaded rod, 2 is a wide disc attached to the neck of the threaded rod, 3 is a horizontal shaft inserted into the tip of the threaded rod, and 4, 4 is a horizontal shaft. 5a represents the nut member body, 5b represents the cover plate of the nut member, 6 represents the screw hole, 7 represents the movable piece of the thread groove, and 8 represents the spring that presses the movable piece. .

The nut member B of the device of the present invention is as shown in FIG. 3A.
A long hole 6 whose one end is a semicircular hole wall with a threaded groove.
' and a nut member main body 5a.

It has a concave surface on one end surface having a thread groove that together with the semicircular hole wall of the elongated hole 6' constitutes a female thread for the male thread of the threaded rod 1, and is slidably fitted into the elongated hole 6'. It consists of a movable piece 7 that is fitted together, a spring 8 that is inserted into the elongated hole 6' and presses the movable piece 7, and a cover plate 5b, as shown in FIGS. 2 and 3.
As shown in Figures B and C, when the cover plate 5b, which also serves as a decorative plate, is pushed in the direction of the arrow, the spring 8 is easily compressed by the pressure, and the cover plate 5b moves leftward □ as shown by the arrow in the figures.

In order to join two pieces of furniture, etc. using the device of the present invention, the fourth
As shown in the figure, holes 11 through which the screw rods 1 can be inserted are prepared in advance in the wooden pieces 9 and 10 at predetermined positions on the furniture, and after inserting the screw rods 1 into these two holes 11, tighten the nuts with your fingers. When the covering plate 5a of member B is pressed, the covering plate 5a and the movable piece 7 are connected by the pin 7a, so the movable piece 7 is pushed to the left and the screw hole 6 widens, so that the threaded rod 1 When the tip is inserted into this enlarged screw hole 6, it is easily inserted.

After that, when you release your finger from the cover plate 5b, the thread groove of the movable piece 7 fits into the thread of the threaded rod, so that one of the two semicircular plates 4°4 provided on the head of the threaded rod 1 is When the screw rod 1 is rotated by raising it up and using a knob, the two pieces of furniture are easily fixed.

After tightening the screws in this way, fold the first half-disk 4.4 to the left and right of the horizontal axis 3 so that it overlaps the disk 2.
Since the disc is flat, the device of the present invention does not interfere with the subsequent use of the furniture.

In addition. In the present invention, the bolt member A and the nut member B are provided with recesses in advance into which they can fit into the pieces of wood 9 and 10 to be assembled, as shown in FIG. It would be more advantageous to do so.

In the present invention, the shape of the nut member B does not necessarily have to be disc-shaped, but may be oval or rectangular.

It is convenient if this nut member is provided with a pin 12 on the surface that comes into contact with the piece of wood as shown in Figure 2, since it can be temporarily fixed just by pressing.

The device of the present invention can be easily removed by performing the above operations in reverse.

As explained above, the device of the present invention is for tightening two wood products with screws, but the screw hole of the nut member is divided in half, and one side is made into a movable piece.

The threaded rod can be easily inserted to a predetermined depth, and as a result, there is no need to turn the threaded rod many times as in conventional screw tightening, and the screw can be tightened with one or two turns.

In addition, the screw rod can be rotated without using tools such as a screwdriver, and the semicircular plate provided on the head of the screw rod can be raised and used as a knob, so there are many advantages such as no need to prepare tools. have

Also, since one assembly is screwed, it can be firmly fixed.
