Description

[Detailed description of the invention] Industrial applications The present invention relates to a jigsaw toy and a punching device for the same.

BACKGROUND TECHNOLOGY In general, as shown in FIG. 9, jigsaw toys are produced by pasting a paper 2a on which a picture 2 is displayed by printing or the like on the surface of a mount 10 made of paperboard of a required thickness, and then drawing an arbitrary shape from the top surface of this picture 2. The mount 1 is divided into stamped plates to form a plurality of jigsaw pieces 3 having a shape. Conventional.

This punching division is performed by first punching out the 10th punching board with a plurality of protruding blades arranged and fixed at regular intervals in the lateral direction and in an arbitrary curved shape. A cutting line 4 is formed, and then a vertical cutting line 5 is punched out using a second punching die having a plurality of protruding blades arranged vertically at regular intervals and in an arbitrary curved shape. A jigsaw piece 3 was formed by forming.

However, according to the above-mentioned conventional technology, the jigsaw piece 3
As shown in FIG. 10, when cut by the blade 7 of the punching die 6, both sides of the cutting line 4.5 are strongly pressed to form valleys 8 and 9, so that each jigsaw piece 30 The disadvantage is that the periphery is inclined and the jigsaw as a whole has many irregularities. Therefore, if the entire jigsaw is viewed only from a certain direction, the surfaces of the valleys 8 and 9 reflect light in opposite directions, making it difficult to see the diagram 2 accurately.

By the way, recently, a synthetic resin film having a prism effect or a lens effect is stretched over the top surface of the picture 2, and the picture 2 changes depending on the angle from which the picture 2 is viewed.
There are pictorial materials that create a sense of perspective. However, if you try to make a jigsaw toy using this picture material and adopt the conventional punching method, the light will be reflected in different directions at the valleys 8.9 formed in the jigsaw piece, so There is a problem in that not only the pictures viewed from above do not appear accurately, but also the pictures do not change or create a sense of perspective and do not form a single body.

Furthermore, the conventional blade part 7 is made of a long and thin strip of steel, which is meandered into an arbitrary shape and placed vertically on a wooden board in the width direction to form a punching die. , by repeated punching processes.

The blade part 7 falls down or slopes and is not perpendicular to the wooden board, so it cuts diagonally to the thickness direction of the mount 1, and the positions of the cutting lines 4 and 5 do not match on the front and back of the mount 1. Therefore, when fitting the reservoir K and the jigsaw piece 3 together, a problem may arise in that it becomes difficult to fit the jigsaw piece 3 together. Such jigsaw toys had the disadvantage of being wasted because they had to be discarded as defective products.

Means for Solving the Problems In order to solve the above problems, the present invention displays a picture on the surface of a predetermined mount, pastes a synthetic resin film on the top surface of the picture, and attaches a plurality of pieces of this mount from the back side. To provide a jigsaw toy characterized by being constructed by punching and dividing into jigsaw pieces of arbitrary shapes.

Furthermore, as a device for manufacturing such jigsaw toys,
To provide a jigsaw toy punching device characterized by having a punching device in which a required number of blade portions each having a U-shaped cross section are arranged and fixed in an arbitrary linear shape with the blade portions oriented in any one of the 10,000 vertical directions.

According to the above-described structure of the present invention, when a specific picture is divided into a plurality of jigsaw pieces of arbitrary shapes, the front surface of the picture remains flat because it is punched and divided from the back side of the picture.
The direction of light reflection is fixed, and the picture of the jigsaw toy having a prism or lens effect can be accurately recognized depending on the desired viewing angle.

Example The present invention will be explained below based on the drawings.

In FIG. 1, a mount 1, which is made up of a synthetic resin film 1o having a prism or lens effect stretched over the upper surface of a specific picture 2, is cut into a plurality of jigsaws of an arbitrary shape by cutting lines 4 and 5 consisting of arbitrary n lines in the vertical and horizontal directions. It is divided into 3 pieces. This picture 2 changes depending on the viewing angle, and the change is caused by the prism or lens effect that the synthetic resin film 10 has.

Furthermore, this mount 1 is punched out from the side opposite to the picture 2, that is, from the back side of the mount 1, to form each jigsaw piece 3. That is, as shown in FIG.
2, place the mount 1 upside down on the paper 12 so that the synthetic resin film 10 faces the paper 12, and the punching die 6 having the blade 13 descends onto the mount 1 to cut the mount 1. It is punched out. Therefore, the troughs 8.9 are formed around the back surface of each punched jigsaw piece 3, but only the cutting lines 4 and 5 appear on the front surface, that is, on the side of the synthetic resin film 10.
The periphery of the surface of the jigsaw piece 3 is flat in all four ways with respect to the central part. Therefore, the surface of the mount 1 is formed as a flat surface without irregularities, so that the function of the synthetic resin film 10 having a prism or lens effect is not impaired.

On the other hand, as shown in FIGS. 2 to 4, the blade portion 13 of the punching die 6 that forms the jigsaw piece 3 described above has a groove shape, and stands upright on both sides of the bottom plate 14 of a predetermined length. A pair of punching blades 15 are fixed together by welding or the like, and claws 16 are embedded in the bottom plate 14 at predetermined intervals.

This claw 16 is used to implant the entire blade portion 13 into the punching die 6 by striking it against the board surface of the bookstore. 5 shows a punching device, in which an upper press 17 is suspended so as to be vertically movable, facing a punching table 11 which is fixedly arranged. A large mount 18 for forming a plurality of jigsaw toys is placed on the upper surface of the punching table 11, and a punching die 6 having a blade 13 is fixedly attached to the lower surface of the upper press 17. By the way, this punched melon 6 has a blade part 13a as shown in FIG.
fAt, which is formed by planting them side by side in the horizontal direction, and a blade, as shown in Fig. 7! +, 3 b are planted in a vertical direction (there are two types: Bl). Therefore, first, attach the punching die 6 of A to the lower surface of the upper press 17 and press the mount 1.
By punching out 8, a horizontal cutting line 4 is formed,
Next, the jigsaw piece 3 is formed by replacing the punching die 6 of B and punching out the mount 18 at a different angle of 90 degrees from the previous punching.

As shown in FIG. 8, the mount 18 is such that several blocks 19 to 22 of jigsaw toys can be simultaneously punched and formed in one punch. 23 in Figure 6. What is indicated by 24 in FIG. 7 is a linear blade portion for forming the blocks 19-22. Furthermore, what is indicated by 25 is a blade portion for cutting the edge of the mount 18.

Effects of the Invention According to the present invention as described above, a jigsaw toy made of a synthetic resin film with a prism or lens effect that changes the picture depending on the viewing angle is attached to 41 jigsaw pieces from the back side of the picture. Since it is formed by punching, no irregularities are formed on the surface of the picture due to punching, and a flat surface is maintained, so that the prism or lens effect of the synthetic resin film is not hindered. Therefore, it is possible to provide a jigsaw toy with a taste that has not existed in the past, and the value of the product itself is not reduced by punching that does not cause problems due to prism or lens effects. Further, according to the punching device of the present invention, since the blade part has a punching die having a U-shaped cross section fixed upright in a pair of left and right sides on the bottom plate, the mechanical strength of the blade part is high, and The blade will not fall down even when used for punching. Therefore, the blade is always perpendicular to the pattern. When cutting a paper pattern with a shape cap and fitting or removing a jigsaw piece with it, it is easy to insert and remove from the top and bottom without getting caught. Further, since the groove-shaped blade portion has improved mechanical strength, the thickness of the punching blade itself can be made one inch thinner than the conventional punching blade.
