Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a door component for constructing various doors such as swing doors, sliding doors, and folding doors.

(Problems to be solved by conventional techniques and ideas) A door construction material (for example, a door construction for a refrigerator door), which is made by attaching a rim material around a plate and filling a recess on the back side with foamed synthetic resin. Conventional manufacturing methods for manufacturing materials (materials) involved many steps and large time losses between steps.
There was a problem that the process did not flow smoothly, resulting in poor manufacturing efficiency and increased manufacturing costs.

In order to solve such conventional problems, the inventor of the present invention proposed, in Japanese Patent Application No. 61-257996, that a gutter-like body was formed by continuously attaching side edge members to both side edges of a strip plate, and the gutter was After producing a door base material as shown in FIG. 7 by injecting liquid foamable resin into the shaped body and foaming it to form a molded body, and cutting the molded body to a required length, As shown in Figure 14,
An edge edge material b is provided on the opposite edge portion of the door base material a,
We proposed a door component with b installed.

When forming a door component in this way, it is required to accurately join the side edge material c and the edge edge material b. In addition to increasing the accuracy of the dimension (length) of b, considerable attention had to be paid to the mutual bonding of edge materials b and c, and there was room for improvement in terms of manufacturing efficiency. In addition, there are still some problems remaining for practical use, such as the need to devise ways to securely and firmly fix the edge member b of the edge.

The object of the present invention is to provide a door component that solves these problems.

(Means for Solving the Problems) The door component 1 of the present invention has side edges 19, 19 of the plate material 2 facing each other by fitting the edges 19 into the fitting grooves 20. Attach the edge materials 3 and 3,
In addition, by filling the thermosetting foamed resin 6 into the gutter-like portion 5 formed by the plate body 2 and the side edge members 3, 3, the foamed resin 6, the plate body 2, and the side edge members The opposite openings 9, 9 from which the foamed resin 6 is exposed are provided with a biting part 31 that acts as an anchor and a edging part 33 that covers the outer edge 32 of the plate body 2. The edge member 10 is attached by biting the biting portion 31 into the foamed resin 6, and the corner member 12 is attached so as to cover the joint portion 11 between the side edge member 3 and the edge edge member 10. It is characterized by being attached.

In this invention, "door component material" refers to materials for constructing various doors (doors) such as opening doors, sliding doors, folding doors, etc. "Attach the corner member 12 so as to cover the joint part 11" means that the part of the joint part 11 that is visible in at least the normal state is
This means that it is covered with the corner member 12 and decorated.

For example, it is applied as a door constituent material constituting the door 1a of a refrigerator, and heat is generated in the gutter-like part 5 formed by the plate body 2 and the side edge members 3, 3 attached to the opposite side edges. Door base material 7 formed by filling the curable foamed resin 6 and integrating the whole (see Fig. 7)
The edge portion edge members 10, 10 are fixed to the opposing edge portions 9, 9 (see FIGS. 2 to 3, and FIG. 7), and the joint portion between the side edge member 3 and the edge edge material 10. A corner member 12 is attached to cover the corner member 11.

The plate body 2 forming the door base material 7 is made of metal plates such as iron plates and stainless steel plates, as well as plate bodies made of paper plates, synthetic resin plates, plywood, or a combination of these materials. Can be adopted depending on the purpose. In addition, the side edge material 3 forming the door base material 7 is provided with screw holes 15, 15 located on both sides of the inner center portion of the base plate 13 having an elongated rectangular plate shape.

A fitting groove 20 is provided into which the edge 19 of the plate 2 is fitted, and a gasket mounting portion 21 is provided on the other side of the substrate 13. Note that the door base material 7 is manufactured, for example, by the manufacturing method disclosed in the above-mentioned Japanese Patent Application No. 61-257996. The manufacturing method is shown in FIG. 6 (for convenience of explanation, the dimensions of the side edge material 3 are shown larger than in reality).
It can be summarized as follows. That is, extrusion molding machines (not shown) are installed on both sides of the strip plate 22 in the direction of transition.
and from each of the extrusion molding machines,
The side edge materials 3, 3 are continuously extruded so that the fitting grooves 20, 20 face each other, and the band plate is transferred to the fitting grooves 20, 20 of the extruded side edge materials 3, 3. 22 are fitted in order to form a gutter-like body 23, and a thermosetting liquid foamable resin (for example, a liquid foamed resin such as polyurethane resin, phenol resin, polyester resin, etc.) is inserted into the gutter-like body 23. 25 is continuously injected, and if necessary, synthetic resin, paper,
A covering material 26 made of cloth, aluminum foil, etc. is covered, and then the liquid foamable resin 25 is sequentially foamed through a foaming passage 27, and the inside of the gutter-like body 23 is foamed from the foaming passage 27. A molded body 29 filled with the resin 6 and in which the strip plate 22 and the side edge members 3, 3 are firmly integrated is extracted, and the molded body 29 thus obtained is cut to a required length. In this way, the desired door base material 7 (see FIGS. 7 and 8) is obtained.

(Effects of the invention) The door component of the invention is constructed by filling the gutter-like part formed by the plate and the side edge material attached to the side edge of the opposite surface with thermosetting foamed resin. Since the door edge member and the corner member are assembled to the integrated door base material, there are fewer steps and no skill is required for assembly, making it possible to manufacture the door very efficiently. Furthermore, since the edge member includes a biting portion that acts as an anchor, the attachment of the edge member to the door base material is ensured. Furthermore, since the corner member is attached so as to cover the joint between the side edge material and the edge edge material, even if there is some dimensional error in the length of the edge edge material, the two edges will be joined together. Not only can the corner member be decorated to look good, but the corner member can also be actively utilized to improve the design effect of the door component.
