Description

[Detailed explanation of the idea] The present invention relates to a panel having a structure in which the core material is formed by foaming.

In a panel having a structure in which a frame material is attached to the edges of a pair of surface materials and a foaming substance is foamed in the interior space to form a core material, conventionally, as a means of adding the frame material to the surface material, Figure 1 and It adopts a structure shown in Figure 2.

That is, the structure shown in FIG. 1 is a structure in which the edges of the surface material 1 are bent inwardly at right angles to each other, and these bent edges 1A are inserted into two grooves formed in the frame material 2 for installation. be.

This structure is undesirable in that the end face of the frame member 2 protrudes from the end face of the surface member 1, which requires a large amount of caulking seal packing 3 when connecting the panels concentrically.

In addition, in the structure shown in FIG. 2, in order to reduce the amount of caulking seal packing, the edge of one surface material 1 is bent back to form a folded edge 1B, and the end surface of the frame material 2 and the end surface of the surface material 1 are bent to form a folded edge 1B. This structure is such that the two are located on substantially the same plane.

According to this structure, since the groove 2B formed in the frame material 2 is inclined in the same direction as the folded edge 1B, for example, as shown in FIG. I need.

Alternatively, it is necessary to process the folded edge 1B so as to insert it into the groove 2B after foaming the core material.

In any case, the work is troublesome, and although it may be preferable, the purpose of the present invention is to create a structure that allows temporary assembly of the frame material to the surface material without the need for special jigs, and also allows for easy temporary assembly retention. The purpose is to provide panels.

To this end, the present invention forms a frame material so that it can be positioned and attached to one surface material, and the other surface material is elastically engaged with the frame material attached to one surface material in a snap manner. It is characterized by being configured so that it can be installed by matching it together.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 6.

The panel shown in FIG. 4 has bent edges 12 including curved portions 11 along at least seven sets of opposing edges of the facing material 1.

The frame member 2' attached to this edge has a complementary groove 13 formed on the side facing the surface member 1 to receive the bent edge 12.

On the side facing the other surface material 1, there is a protruding shoulder portion 15' having a shape that follows the inner surface of the bent edge and has a shape substantially similar to the curved portion 11.
are formed outward, and the protrusion 14 for forming the groove 13 is omitted.

The remaining two edges of the facing material 1 are bent as shown in FIG. 1, and a conventional frame material 2 is attached thereto.

However, a bent edge having a curved portion 11 can also be formed on the remaining two edges.

The procedure for temporarily assembling a panel having such a structure will be explained with reference to FIG.

Here, an embodiment will be described in which a bent edge 12 is formed on the side of the surface material 102 as shown in FIGS.

First, one of the facing materials 1 is placed as shown in A and B of the same figure, and the frame material 2' is bent into the groove 13 and the edge 12
Add by inserting.

In this case, this can be easily done by tilting the frame member 2' in the direction of the arrow according to the shape of the bent edge 12, as shown in FIG.

In this way, frame members 2' are attached to two sides as shown in the same figure and E, and frame members 2 are added to the remaining two sides as before.

Next, as shown in FIG. F, the other surface material 1 is first fitted with one bent edge 12 into one frame material 2, and then pressed in the direction of the arrow.

At this time, the frame members 2.2' attached to the four sides are assembled to each other, as is clear from Figure E, so that no inward tilting occurs.

By this pressing of the surface material 1, the other bent edge 12 is elastically deformed, and the curved portion 11 is formed into the protruding shoulder 15 of the frame material 2'.
It is installed in a snap manner by engaging the .

Therefore, once the temporary assembly is completed, the surface material 1 and the frame material 2' cannot be easily separated.

After this, a foam material is foamed inside to complete the panel.

As explained above, the panels of the present invention do not require any special jigs for temporary assembly and can be attached in a snap manner by simply pressing the surface material, which improves work efficiency and allows the panel outer periphery to be fixed by the snap action. The strength of the material is also improved.

Incidentally, in the above-mentioned embodiment, a structure in which the snap action is obtained mainly by elastic deformation of the bent edge was explained, but for example, as shown in FIG. A tongue portion 1 having the same external shape as the protruding shoulder portion 15' and having an L-shaped cross section.
It is also possible to form 5.

Of course, it is also possible to form the tongue portion 15 on the side having the groove 13, thereby strengthening the attachment force.

In this way, the shapes of the folded edges and grooves are not limited.
