Description

[Detailed Description of the Invention] The present invention relates to a hinge used for a folding part of a doll house toy or a pencil case.

Doll house toys, pencil cases, loose-leaf notebook covers, etc. are made of relatively thick boards made of cardboard or other material coated with resin.
A part of it had a bendable hinge part.
Conventionally, this bendable hinge portion was formed only from resin by completely dividing the core material and adhering resin covering the core material.

As a result, this hinge portion becomes significantly weaker than other portions, which is a major factor in shortening the lifespan of doll house toys and the like. In addition, in the manufacturing process, the core material had to be divided one by one, resulting in an increase in the number of steps and complication.

The present invention was developed in view of the above-mentioned drawbacks, and includes a core material in which a part of the bent portion is cut out along the bending line, and a bending groove is formed on the outside of the bending line in the remaining core material. The object of the present invention is to provide a hinge that has the same strength as other parts and is easy to manufacture by coating with resin through welding processing.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is an overall perspective view of one embodiment, FIG. 2 a is a cross-sectional view taken along line AA in FIG. 1, and FIG. 2 b is a cross-sectional view taken along line A--
FIG. 3, a cross-sectional view taken along line B, shows an example in which the hinge of this embodiment is used in a doll house toy.

In these drawings, reference numeral 1 denotes a plate-shaped core material made of cardboard or the like, and a bent portion 2 is formed in the middle thereof. Reference numeral 3 designates an elongated cutout hole cut out in the center of the bent portion 2 along the bending line 2a. Reference numeral 4 denotes a bending groove formed on the outside of the remaining core material 1 of the bent portion 2, and is formed by half-cutting or press processing from the end of the cutout hole 3 to the end of the core material 1. . By forming the cutout hole 3 and the bending groove 4 in the bent portion 2 of the core material 1 in this manner, the core material 1 can be easily bent at the bent portion 2.

Reference numeral 5 denotes a resin that covers the outer periphery of the core material 1 by welding, and the portion covering the cutout hole 3 is integrated by welding the upper and lower resins on both sides by welding. By integrating the resin portion covering the cutout hole 3 in this way, the resin 5 does not float when the core material 1 is bent.
Prevents it from turning over.

The hinge section configured in this manner is used, for example, in the folding section of a doll house toy shown in Figure 3, which is normally folded and when played, each block section is unfolded to form the main body of the house, or the folding section of a pencil case. Used for folding parts such as lids and covers of loose-leaf notebooks.

Note that the cutout holes 3 are not limited to the illustrated elongated holes, but may also be, for example, a plurality of short holes formed at appropriate intervals along the bending line 2a.

As described above, according to the present invention, a cutout hole is formed by cutting out a part of the bent part of one sheet of core material along the bending line, and a bending groove is formed on the outside of the bending line of the remaining core material. Since the single core material is formed and coated with resin by welding, the resin coating operation in the manufacturing process is facilitated. Furthermore, since the bent portion has a hinge structure in which the remaining core material other than the cutout hole is present, it has the same strength as the other portions and can withstand long-term use. Furthermore, since the resin on both the upper and lower surfaces covering the cut-out hole is welded, the resin will not float or curl up during bending, and will not impair usability or aesthetics.

Claims (1)

[Claims for Utility Model Registration] A hinge comprising a core material having a bent portion and coated with resin by welding processing, and having the following requirements. (a) Cut out a part of the core material along the bend line at the bent part of a single plate-shaped core material to form a cut-out hole of an appropriate width. (b) Form a bending groove along the bending line by half-cutting or pressing, etc., on the outside of the bending line of the remaining core material other than the cutout hole in the bent part. (c) Welding the resin on both sides covering the cutout hole by welding.
