Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a toy jigsaw puzzle and an improvement in its manufacturing method. Therefore, the industrial field of application of this invention is the field of manufacturing and selling jigsaw puzzles, in short, the toy industry.

Conventional technology Jigsaw puzzles have recently become very popular and have become a popular play object for children, and their educational effects are also great, attracting the attention of mothers. It is also manufactured and sold in large quantities as a bonus or promotional product.

However, there is no need to cite any particular literature.〈Conventional art materials for jigsaw puzzles are made by manufacturers who select certain materials to make into jigsaw puzzles, so for the user, the materials are indispensable. Moreover, since they are mass-produced, children often receive the same items over and over again as bonus items, and are often disappointed. Furthermore, the cutting of each chip had already been done by the manufacturer, and the only interest was in assembling it.

Problems with the conventional technology Therefore, with the jigsaw puzzles of the conventional technology, it is not possible to play with art materials that the users themselves love or specially select, but only with mass-produced art materials selected by the manufacturer. Ta. Furthermore, since the chip cutting was done by the manufacturer, the only interest was in assembling it, and the educational effect and attachment to it were insufficient.

Furthermore, if the chips were cut into pieces at random, it would not be as good as a jigsaw puzzle, and the result would be a boring work with almost no fun as a game.

Means for Solving the Problems As a means for solving the problems of the prior art described above, in the present invention, a single sheet made of a soft material such as a foamed synthetic resin such as expanded polystyrene, urethane, foamed acrylic, or foamed polyethylene is used. A board material for jigsaw puzzles consisting of a single board, characterized in that a large number of chip dividing lines are provided on the back side of a soft board-like body, which have unevenness that can fit an appropriate number of male and female parts for jigsaw puzzles. is provided.

In addition, as a method for manufacturing the above-mentioned jigsaw puzzle, the chips are divided by printing the chip dividing line for the jigsaw puzzle directly on the back of the soft plate, or by printing it on a piece of paper and pasting it on the back of the soft plate. The first step is to prepare a board for jigsaw puzzles with lines, the second step is for each person to paste or draw on the opposite side (surface) with any art material, and to use an appropriate tool such as a scroll saw or nichrome wire cutter. Provided is a method for manufacturing a jigsaw puzzle, which includes the step of cutting the chip at the chip dividing line using a suitable means to finish it into a large number of independent chips.

Embodiment The object of the present invention is the improvement of jigsaw puzzles and the manufacturing method thereof.To explain with reference to the drawings, 1. In the first step of the manufacturing method of the present invention, as shown in FIG. Same as the situation.

Chip parting lines 3 for jigsaw puzzles can be printed directly on an integrated soft plate-like body 4 made of a soft material such as foamed synthetic resin, such as styrofoam, urethane, foamed acrylic, or foamed polyethylene, which is easy to cut and inexpensive, or as shown in FIG. As shown, a jigsaw puzzle plate material 6 with chip dividing lines 3 provided on the back side is prepared by printing on a piece of paper 5 and pasting it onto a soft plate-like body 4.

Each chip 2 is as shown in Fig. 1, and the number of protrusions 1 seen in a plan view is for illustrative purposes only.In the illustrated example, the protrusions are 6WJ, but the number of protrusions 1 is 6WJ, but it is not limited to this. That doesn't mean it's true. Further, the shape of the unevenness 1 can also be variously modified. Incidentally, since it is a matter of course that the adjacent chips 2' of each chip 2 have a shape in which the convex portion and the four portions fit into male and female, the concave portions will not be particularly explained.

The material of the soft plate-like body is styrene board,
Any material that can be easily cut and separated with a scroll saw or nichrome wire cutter, such as styrene paper, is suitable.

A soft cork board, cardboard or rubber board may also be used.

Note that the thickness of the jigsaw puzzle board 6 is most suitably about 3 to 5 mm for reasons of cutting, assembly in games, and cost, but is not limited to this.

In the next step, the user can attach his/her favorite photograph, poster, magazine, etc. to the surface of the jigsaw puzzle board 6, or draw on it himself using acrylic thread. create.

Then, as shown in FIG. 3, use a scroll saw 8 to cut into a row of vertical or horizontal strips along the chip dividing line 3 provided on the back side, and then cut the strips horizontally or vertically. Each chip is separated into pieces as shown in FIG. 4, and the product of the present invention is completed.

How to use it is no different from a normal jigsaw puzzle.

For cutting, in addition to the thread saw 8, it is also possible to use a very fine file or, if the piece of paper is thin, a nichrome wire cutter.

Furthermore, although the thickness of the paper pieces (including paper as well as synthetic resin films such as polyethylene sheets) 5 and the art material 7 in FIG. 2 are significantly exaggerated relative to the soft plate-like body 4, in the actual example they are extremely thin pieces.

Effects As explained above, according to the present invention, it is possible to easily provide a self-made jigsaw puzzle that the user can enjoy using any suitable art materials of his/her choice.

Furthermore, since it involves not only simple assembly like conventional products, but also the process of chip cutting, it creates an even greater sense of satisfaction and fulfillment, and its attachment and educational effects are outstanding.

In addition, chips can be easily cut by using an inexpensive scroll saw or nichrome wire cutter, without using expensive special blades like conventional products. At the same time, you can easily enjoy making your own special handmade jigsaw puzzles at a low price.

Furthermore, each chip cut along the chip dividing line has a shape similar to that of a commercially available jigsaw puzzle, making the game even more interesting.

Claims (2)

[Claims] (1) On the back side of a soft plate-shaped body made of a soft material such as foamed synthetic resin such as styrofoam, urethane, acrylic foam, or polyethylene foam, there are irregularities that can fit into an appropriate number of male and female jigsaw puzzles. This jigsaw puzzle material consists of a single board, and is characterized by having a large number of chip dividing lines, and on the front side, each person can place any desired art material of their choice. (2) A board material for jigsaw puzzles with a chip dividing line provided by printing the chip dividing line directly on the back of the soft plate or by printing it on a piece of paper and pasting it on the back of the soft plate. The first step is preparation, the second step is for each person to paste or draw any drawing material on the opposite side (surface), and the second step is cutting at the chip dividing line using an appropriate means such as a scroll saw or nichrome wire cutter. A method for manufacturing a jigsaw puzzle, comprising a step of finishing it into a large number of independent chips.
