Description

[Detailed description of the invention] Industrial field of application The invention relates to a fastening device for connecting a cabinet to a top plate of a sink, cooking table, washstand, etc. whose top plate is made of a molding material such as synthetic resin. .

Conventional Structures and Problems The top plates of sinks and the like these days are made of molding materials such as synthetic resins and composite materials thereof for the purpose of increasing luxury and interior design. The top plate and the cabinet can be connected by using a frame-shaped jig 10 as shown in FIG. 10
When bonding using , a large number of jigs are required in order to produce a wide variety of products in small quantities, which has the disadvantage that it takes time to replace the jigs and the management of the jigs is complicated.

Purpose of the invention The present invention solves the above-mentioned conventional drawbacks.
The purpose is to securely and easily attach a top plate to a cabinet.

Structure of the Invention In order to achieve the above object, the device for attaching the top plate and the cabinet of the present invention includes integrally forming a planar L-shaped protrusion at a suitable location on the back of the top plate, and adhering into the protrusion. In this structure, a square piece of wood is attached along the cabinet through a glue, and the piece of wood and the cabinet are fastened together with a fastener such as a screw.

The above configuration has the effect that the work of fastening the top plate and the cabinet is facilitated, and the top plate and the cabinet are securely fixed.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In the figure, reference numeral 1 denotes a cooking table, and a top plate 3 molded from a molding material such as synthetic resin is placed on top of the cabinet 2. At a suitable place on the back side of the top plate 3, there is a protrusion that is approximately L-shaped in plan. A portion 5 is integrally formed, and its corner portion is a cutout 5a. A piece of wood 6 is attached along the protrusion 5 with a polyester adhesive 7 interposed therebetween. The top plate 3 is integrally connected to the cabinet 2 by fastening the wooden piece 6 on the back side of the top plate 3 and the cabinet 2 with screws 4.

In the above configuration, the top plate 3 to the cabinet 2
For installation, first, a square piece of wood 6 is attached along the inside of the protrusion 5 which is integrally molded when the top plate 3 is formed, via an adhesive 7. At this time, the remaining adhesive 7
escapes from the corner notch 5a of the protruding strip 5, the wood piece 6 comes into close contact with the protruding strip 5, the mounting position shift due to the adhesive 7 is eliminated, and the mounting dimensional accuracy is improved. In addition, since the protrusion 5 is L-shaped in plan, the piece of wood 6 can be aligned vertically and horizontally, ensuring reliable positioning.
Moreover, it is easy to use, and the adhesive 7 can also be applied to the protrusion portion 5.
is applied, the adhesive area becomes larger,
The effect is that the adhesive force is increased and the installation strength is improved.

In this way, according to this embodiment, there is no need for a conventional jig, and the work of gluing the pieces of wood 6 is simplified.

In the above embodiment, the linear portion of the protrusion 5 is formed continuously, but it may be formed discontinuously as shown in FIG. According to this embodiment, when the linear portion of the protruding strip 5 is long, the adhesive 7 accumulated in the linear portion is released and the adhesive strength is increased.

Effects of the Invention As described above, according to the present invention, a planar approximately L-shaped protrusion is integrally formed on the back surface of the top plate, and a piece of wood for fastening to the cabinet is attached within this protrusion using an adhesive. Because of this structure, compared to the conventional jig method, its management and workability are easier, and the wood pieces are regulated vertically and horizontally, so that the mounting position is always constant, and various other effects are obtained.
