[Detailed description of the invention] This invention is suitable for attaching and fixing one furniture board to another furniture board when assembling furniture such as a chest of drawers or a water closet. This relates to a fixing structure for furniture board materials used when attaching and fixing left and right side panels to a top plate or bottom.

In recent years, when it comes to furniture, especially chests of drawers, water closets, etc.
In order to reduce transportation space and, in turn, reduce transportation costs, we manufacture furniture panels such as top panels and side panels, as well as parts such as accessory cases, at the factory stage, and then replace the left and right side panels at the site of use. Attached to the top plate,
Methods of assembling furniture boards and the like to complete furniture, such as fixing them, are widely used. Various improvements have been made to the fixing structure of furniture manufactured by this on-site assembly method in order to facilitate and quickly attach and fix furniture panels and the like. However, although furniture panels can be easily installed in these fixed structures,
Due to weak fixation, some pieces of furniture cannot have sufficient strength as furniture. On the other hand, by increasing the number of bolts and the like, it is possible to securely fix the furniture board material, but it takes a lot of time to attach and fix the furniture.

The present invention was developed in consideration of the above circumstances, and its purpose is to provide a fixing structure for furniture panels that can easily and firmly attach and fix one furniture panel to another furniture panel. It is about providing.

The furniture board fixing structure according to the present invention has a head fixed to one furniture board and protruding from the surface of the board, in which one furniture board is attached and fixed to the other furniture board. a fixing screw having an overhanging stepped portion at the top of the head; and a block fitted into the other furniture board, the surface of the block and one side connected to the surface meeting the surface of the furniture board. The fitting opening of the fitting groove into which the head of the fixing screw is fitted into the side surface of the block is opened so that the head of the fixing screw is approximately L-shaped on the surface of the block. The fitting groove is formed so that the fitting groove can be moved, and a plate spring is provided in the deep part of the fitting groove, and the head of the fitted fixing screw presses down a convex part provided on the plate spring and is fitted. It is characterized by having a fitting block that reaches the inner part of the matching groove.

The fixing screw in the present invention is, for example, a substantially cylindrical support with a narrowed distal end and a slit, and has a threaded portion formed on the inner surface of the proximal end and a spherical body loosely held inside. A screw support that is inserted from the tip into a fixing hole drilled in a furniture board material, and a screw support that is inserted into the support from the proximal side and screwed into the threaded part to be supported by the support. At the same time, it is preferable that the fixing screw is configured to press the spherical body toward the distal end of the support to open the cut end of the support to the outside.

It is a member that is fitted from the tip into a fixing hole 7 (hole diameter corresponding to the support) drilled in the surface of the member, and has a screw portion 8 formed on its proximal inner surface to be screwed into the fixing screw 2. On the other hand, a spherical body 9 having a shape similar to a chicken egg is freely held inside. The shape of the spherical body 9 is
It may also be a sphere, an ellipsoid, etc. Note that 10 is a stop for preventing the spherical body 9 from coming out from inside the support.

The fixing screw 2 is a screw having a stepped portion 12 on its head 11 as shown in FIG. It is supported by a support 1. Further, during this screwing, the fixing screw 2 presses the spherical body 9 toward the distal end side of the support to open the cut distal end portions 4 outward. The fixing screw 2 may have any shape as long as it can fit into the fitting block 3 at the stepped portion 12, etc., and preferably has a wide fitting surface.

Furthermore, the fitting block 3 is a trapezoidal block made of wood, metal, plastic, etc., as shown in FIG. An L-shaped groove, that is, a fitting groove 14 that fits into the head 11 is formed, and as shown in detail in FIGS. A substantially U-shaped leaf spring 15 is provided. and,
The head 11 of the fixing screw 2 is inserted into the fitting groove 14 of the block 3.
When the head 11 is inserted into the deep part of the groove 14, the step 12 of the head 11 is inserted between the leaf spring 15 and the bottom of the groove 14, and the leaf spring 15 is inserted into the step 12. and the fitting surface 16 in the groove 14 (FIG. 5), the leaf spring 15 biases the head 11 of the fixing screw 2 in the direction away from the block surface 13, thereby fixing the screw. The screw 2 is fixed to the block 3. Note that the fitting groove 14 is
The shape is not limited to the L-shape, but may be a shape resembling a T-shape in which the long groove portion of the groove 14 extends toward the bent portion, as shown by the two-dot chain line in FIG. 4, for example. In the case of a fitting groove similar to the shape of a square, groove machining becomes much easier. Also,
The size of the fitting block 3 is as shown in FIG.
corresponds to Furthermore, the shape of the block 3 is not limited to the trapezoidal block of the embodiment, but is preferably one that can be easily molded.

Next, a method for attaching and fixing the shelf board 17 to the side plate 6 using the fixing structure of the embodiment will be described.
At the factory stage, an appropriate number of fixing holes...7 are regularly drilled at appropriate intervals on the surface of the side plate 6.
Furthermore, dovetail grooves 18 are formed at predetermined locations on one end of the shelf board 17 (FIG. 7). Then, the fitting block 3 is fitted into the dovetail groove 18 using a mallet or the like. The fitting of the block 3 may also be carried out at the furniture assembly site.

At the furniture assembly site, the screw support 1 is first inserted into any fixing hole 7 of the side plate 6 by hitting it with a hammer, and then the fixing screw 2 is inserted into the fixing hole 7 of the side plate 6.
is inserted into the screw support 1 from the proximal side and screwed into the screw portion 8 using a driver or the like, so that the fixing screw 2 is supported by the screw support 1. At this time, as shown in FIG. 3, the spherical body 9 is pressed by the fixing screw 2 and moves toward the tip side of the support 1, and the cut tip 4 opens outward and the fixing hole is opened. By coming into pressure contact with the side wall of the fixing screw 7, the fixing screw 2 is fixed to the surface of the side plate 6 and will not fall out from the fixing hole 7. In the case of the embodiment, by providing the hook part 5..., the hook part 5... bites into the inside of the side wall of the fixing hole 7 when the cutting tip part 4... opens, so that the fixing screw 2 is made even stronger. It is fixed to the side plate 6. Further, if the fixing hole 7 has a shape that becomes narrower at the bottom side of the hole, the support 1
The cutting tip 4... is strongly pressed against the side wall of the fixing hole,
The screw 2 is firmly fixed.

Next, as shown in FIG. 7, while keeping the shelf board 17 perpendicular to the side board 6, the shelf board 17 is moved downward in the direction of arrow A, and the head 11 of the fixing screw 2 is inserted into the fitting groove of the fitting block 3. 14. Next, the shelf board 17 is moved horizontally in the direction of arrow B, and the head 11 of the fixing screw 2 is inserted deep into the fitting groove 14. At this time, the head 11 of the screw 2 is urged in the direction away from the block surface 13 by the leaf spring 15, as described above, and as a result, the fitting block 3 is moved away from the step 12 of the head 11. It is held between the surface of the side plate 6. Therefore, the shelf board 17 will be firmly fixed to the side board 6.

The above explanation is about fixing the shelf board to the side board, but when fixing the partition board etc. to the side board,
Alternatively, it can be similarly applied when attaching and fixing the side plate to the top plate.

As explained above, the furniture board fixing structure of the present invention requires only three simple operations: inserting a screw support, screwing a fixing screw, and fitting the screw with a fitting block. Since the furniture board material can be attached to the other furniture board material, the furniture board material can be attached easily and quickly. Also,
In the fixing structure of the present invention, when the fixing screw is screwed in, the cut tip of the screw support opens outward and presses against the side wall of the fixing hole, so that the fixing screw is firmly fixed, and the head of the fixing screw is fitted. By adopting a structure in which the block is clamped between the screw head and the furniture board material by the elastic force of the spring means when it is fitted into the fitting groove of the inserting block, the furniture board material can be fixed more easily than before. It becomes much stronger. Furthermore, the fixing structure of the present invention can be widely used for fixing unit furniture, etc.
