Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The present invention allows link mechanisms and other skeletal structures in moving toys to be easily and freely configured, and through the creation of such structures and observation of their operation. This invention relates to a freely assembling member used for a moving toy that makes it interesting to learn mechanical knowledge.

Conventional technology Traditionally, children in elementary and junior high schools have sometimes been asked to observe the movement of moving toys, or to have them disassemble the toys in order to learn the mechanisms of their movements and mechanistic knowledge. However, in this type of learning, children are simply asked to disassemble and observe ready-made toys, which does not give children the freedom to create. Since this was impossible, it was also impossible to allow students to experience the wonders of mechanical mechanics, where even slight differences in structure and mechanism can cause completely different operations.

Therefore, as seen in Japanese Utility Model Application Publication No. 59-93593, the inventor of the present invention proposed a flexible toy that can be used in a movable toy made by connecting and combining a connecting member with a large number of holes and an arm member using a screw rod or the like. However, as children in elementary and junior high schools have become clumsy in using tools such as knives these days, we have developed an arm member that is easy to cut and has the required strength by cutting it to the required length. When cutting or connecting circular holes to form elongated holes (cam grooves), the cut edges are not straight or clean.

Problems to be Solved by the Invention This invention is a flexible assembly method for cutting and forming arm members that are easy to cut and have a specified strength. The purpose of this project is to provide materials for use.

[Structure of the idea]

Means for Solving the Problems In view of the above points, the present invention provides an arm member in the form of a long and narrow plate made of a synthetic resin low-foam material that is easy to cut and has a predetermined strength, with a large number of circles spaced at equal intervals. A hole is drilled, and a groove is carved in the width direction in the middle part of each circular hole, and a groove is carved in the longitudinal direction in contact with the circumference of each circular hole, and a groove is carved in the longitudinal direction between the circular hole and the groove in the longitudinal direction. It is an object of this invention to solve the above-mentioned drawbacks by providing a freely assembling member for use in a movable toy, in which a cam groove with a long hole of a desired shape can be formed by removing a surrounding plate surrounded by a movable toy.

Function The present invention makes it easy to cut and forms a desired shape by making a deep straight cut with a knife along a groove carved in an arm member having a predetermined strength, or by pressing with a screwdriver. .

Embodiment An embodiment of the present invention will be described below based on the drawings. The freely assembling member according to the present invention is composed of an arm member 1 and a connecting member 2.

The arm member 1 is made of a low-foamed synthetic resin material such as styrene, ABC, etc. that has a predetermined strength and is easy to cut.The arm member 1 is formed entirely into a long and thin plate shape, and has a large number of circular holes 3, 3a, etc. at the same intervals. A groove 4, 4a... is formed on the center line in the longitudinal direction, and a groove 4, 4a... is formed in the intermediate part of each circular hole 3, 3a... in the transverse direction, and a groove 4, 4a... is formed in contact with the circumference of each circular hole 3, 3a... Grooves 5, 5a are cut in the longitudinal direction.

In addition, the shape of the grooves 4, 4a..., 5, 5a can be made by cutting with a knife, grooves, notches, etc. When forming deep and shallow grooves to form a desired shape, when the grooves are shallow, they can be made by making deep cuts in a straight line with a knife. Insert it, and when it is deep, use it to press down with a screwdriver, etc.

Next, the connecting member 2 is made of metal and is formed into an elongated plate shape as a whole, and grooves 6, 6a, . . . are cut in the transverse direction at predetermined unit intervals.

Reference numerals 7, 7a, . . . indicate a large number of connecting plates separated from each other by grooves 6, 6a, . . . , and holes 8, 8a, .

Next, to explain the usage state of the freely assembling member used for the movable toy according to the present invention, the arm member 1 made of a synthetic resin low foam material that has a predetermined strength and is easy to cut is inserted into the grooves 4, 4a. Depending on the shape and depth of the grooves 4, 4a..., the grooves 4, 4a... are bent and stretched several times, or cut and pressed with a tool such as a knife or screwdriver, and cut into a predetermined length, and then the circular holes 3, 3
A... and the surrounding plates 9, 9a... surrounded by the grooves 5, 5a are cut with a tool such as a knife or a screwdriver, and pressed to make them fall out, thereby forming the circular holes 3, 3a...
are connected to form a long cam groove 10.

Next, the connecting member 2 made of metal has grooves 6, 6a...
It can be easily bent 90 degrees along the line, and it can be easily divided by bending and stretching several times, so by such bending and dividing operations, an arbitrary number of connecting plates 7, 7a... can be bent into an arbitrary shape. This allows the connecting piece 11 to be formed freely.

FIG. 5 shows an example of a moving toy composed of arm members 1, 1a, etc., connecting members 2, 2a, etc., and two book crank arm 1
5 and 15a are fixed in opposite directions by 180 degrees, and the pivot 16 is inserted into the hole bored in the crank arm 15, 15a and the circular hole 3, 3a of the arm member 1, 1a, and the shaft 16 is rotatably connected. ing.

Further, on the side of the board 12, a cam follower 18 is provided, which is fixed to the circular holes 3, 3a of the arm members 1b, 1c by screwing the arm members 1b, 1c vertically from the back side with a screw rod 17 through the connecting piece 11. The other end is slidably fitted into the cam groove 10 of the arm members 1, 1a.

Also, an arm member 1 screwed onto the side of the board 12
Arm members 1d and 1e are rotatably attached to the ends of arms b and 1c by pivot shafts 19, and arm members 1
Arm members 1f, 1g are rotatably attached to the tips of arms 1f, 1e with pivot shafts 20, and non-slip claws 21 are fixed to the other ends of arm members 1f, 1g. 1g, the tips of the arm members 1, 1a are rotatably mounted on a pivot 22.

On the other hand, wheels 23, 23a are rotatably mounted below the rear end of the base plate 12 by means of a connecting piece 11.

In such a toy, the arm members 1, 1a are cranked by activation of the drive unit 13, and the cam groove 10 moves back and forth and rotates around the cam follower 18, and this movement causes the arm members 1f, 1g to move.
It moves up and down and step by step, making the toy move lamely forward.

[Effect of idea]

In short, the present invention involves drilling a large number of circular holes 3, 3a, etc. at equal intervals in an arm member 1 in the form of a long and narrow plate made of a synthetic resin low-foaming material that is easy to cut and has a predetermined strength. Since grooves 4, 4a... are cut in the intermediate part of each circular hole 3, 3a... in the transverse direction, the arm members 1, 1a... can be cut to a desired length along the grooves 4, 4a... Grooves 5, 5a are carved in the longitudinal direction in contact with the circumference of each circular hole 3, 3a...
Since the surrounding plates 9, 9a surrounded by the grooves 5, 5a in the longitudinal direction can be removed to form the long hole cam groove 10 of a desired shape, when the surrounding plates are removed, the grooves 5 , 5a, etc., using tools such as a knife, screwdriver, etc., or by hand, and the cut surfaces and edges can be finished straight, smooth, and neatly.

Therefore, flexible structures and link mechanisms can be easily configured, and furthermore, a wide variety of moving toys can be freely and easily configured by assembling mechanical elements such as drive devices and wheels, and the structure can be changed freely. This makes it easy to observe the changes in the motion of the toy and the main body, which has great practical effects, such as giving learners a strong desire to create and helping them acquire a variety of mechanistic knowledge. It is something.
