Description

[Detailed description of the invention] (Field of industrial application) The present invention is a shape-changing toy in which an extensible member is formed by an external member and an internal member, and both members can rotate only at a predetermined position of the internal member. This invention relates to a telescopic rotation mechanism.

(Prior Art) Conventionally, as a telescopic rotation mechanism in this type of shape-changing toy, for example, as shown in FIG.
1 and a cylindrical inner member 12 constitute an extensible member 10, and the outer member 11 and the inner member 12 are rotated simultaneously with mutual expansion and contraction. However, in this telescopic rotation mechanism, the external member can be freely rotated at any position on the internal material, so when this telescopic member is used for the arms, legs, etc. of shape-changing toys, etc. However, there is a problem in that parts that should not be rotated tend to rotate and lose their shape, and a solution to this problem has been desired.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned points of view, and is particularly aimed at a shape-changing toy in which the outer member and the inner member can rotate only at predetermined positions. The purpose is to propose a telescopic rotation mechanism.

(Means for solving the problem) As a means for solving the above problem, the telescopic rotation mechanism in the shape-changing toy according to the present invention is as follows:
It is characterized by having an external member and an internal member having the following configuration, one or both of which are linked to the structural members of the shape-changing toy.

(a) The internal member has a substantially prismatic main body, an annular groove provided at an appropriate portion of the main body, and a flange provided at one end of the main body.

(b) The above-mentioned outer member is provided with a hollow portion for storing the inner member, and the hollow portion has a size that allows the collar portion of the inner member to rotate, and one end of the hollow portion is approximately connected to the main body of the inner member. Square through holes of the same shape and size must be formed.

(Operations and Effects of the Invention) As described above, according to the telescopic rotation mechanism of the shape-changing toy according to the present invention, the substantially prismatic inner material main body has a prismatic through-hole in the outer material of substantially the same shape and size. Since the outer material penetrates through the inner material, it is possible to expand and contract the outer material along the longitudinal direction of the inner material. However, in normal cases, the outer corner of the inner material body and the inner corner of the square through hole engage, and the outer material penetrates the inner material. It cannot rotate around the material. However, at the position where the annular groove of the inner member faces the square through hole of the outer member, the annular groove does not engage with the inner corner of the square through hole, so the outer member cannot freely rotate around the inner member. can. Therefore, although the outer member and the inner member can freely expand and contract, they can only rotate at a position where the annular groove of the outer member faces the rectangular through hole of the inner member. Therefore, in a shape-changing toy, the external member does not rotate unnecessarily, making it ideal for, for example, arms, legs, etc. when the shape changes to a robot.

(Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral A indicates the telescoping and rotating mechanism in the shape-changing toy according to the present invention. The telescopic rotation mechanism A in this shape-changing toy has an external member 2 and an internal member 5.
The elastic member 1 is formed by the above.

The outer member 2 has a rectangular cylindrical shape, and has a storage space for the inner member formed therein, and has a rectangular through hole 3 bored in the center of its upper surface 2a. The inner member 5, which is housed inside the outer member 2 and extends and retracts freely from the rectangular through hole 3 in the upper part thereof, has a main body 8 formed in the shape of a square column, and has an upper part 8a and a lower part 8b. An annular groove 6 is formed therebetween, and a collar portion 9 is provided protruding from the lower end of the lower portion 8b. The upper body part 8a and the lower body part 8b have the same shape and approximately the same size as the rectangular through hole 3 bored in the upper surface 2a of the external member 2, and can be easily moved up and down within the rectangular through hole 3. Furthermore, the storage space for the outer member 2 is formed to be large enough to allow the collar portion 9 to rotate.

In normal cases, one or both of the inner member 5 and the outer member 2 are connected to the structural members of the shape-changing toy.

According to the telescopic rotation mechanism A in the shape-changing toy described above, since the substantially prismatic inner material main body 8 passes through the prismatic through hole 3 of the outer material of substantially the same shape and size, the outer material first The material 2 can be expanded and contracted along the longitudinal direction of the inner material 5 (Fig. 2a,
c). In a normal case, the outer corner of the inner member main body 8 and the inner corner of the rectangular through hole 3 are engaged, so the outer member 2 cannot rotate around the inner member 5. However, at the position where the annular groove 6 of the inner member 5 faces the rectangular through hole 3 of the outer member 2 (FIG. 2b), the annular groove 6 does not engage with the inner corner of the rectangular through hole 3. Further, since the storage space for the outer member 2 is formed to be large enough to allow the collar portion 9 to rotate, the outer member 2 can freely rotate around the inner member 5. Therefore, although the outer member 2 and the inner member 5 can be freely expanded and contracted, they can only rotate at the position where the annular groove of the outer member 2 faces the rectangular through hole of the inner member 5. can. Moreover, the telescopic rotation mechanism described above can be achieved with a simple structure.

Note that the external member 2 is not limited to a square cylindrical shape,
For example, it may have a triangular cylindrical shape, a hexagonal cylindrical shape, etc., and the rectangular through hole 3 formed in the upper surface 2a is not limited to a rectangular shape, but may be a triangular shape, a hexagonal shape, etc. In this case, the main body upper part 8a forming the internal member 5
It goes without saying that the shape of the lower part 8b of the main body is the same as the shape of the rectangular through hole 3. Further, it is preferable that the annular groove 6 is formed to have a slightly smaller diameter than the upper main body 8a and the lower main body 8b which are connected to each other above and below, but the annular groove 6 is not necessarily limited to this.

Next, what is shown in FIG.
This shape-changing toy B is configured to reversibly change from an adhesive tape storage stand-like form to a robot-like form.

In the above-mentioned shape-changing toy B, the elastic member 1,
1. A toy main body 10 is formed by a base body 20 and arm members 30, 30. Further, an adhesive tape 21 is detachably attached to the base body 20 of the toy body 10. Reference numeral 22 designates a cover member having a hollow interior and movably attached to the base body 20. Support shafts 23, 23 are provided protruding from approximately the center lower part of both sides of the cover member 22. The support shafts 23, 23 are connected to guide grooves 2 formed in the rear portions of both sides of the base body 20, each having a substantially inverted L shape.

can be covered or exposed. 2
Reference numeral 5 indicates a head portion formed approximately at the center of the rear surface of the base body 20 so as to be able to rise and fall freely.

The extensible members 1, 1 are formed by external members 2, 2 and internal members 5, 5 to be expandable and contractible, and the external members 2, 2 have a rectangular cylindrical shape, and the upper surfaces 2a, 2a Square through holes 3, 3 having a rectangular shape are bored therein. Further, an inner member 5 that is housed inside the outer members 2 and 2 and that extends and retracts from the rectangular through hole 3 is a rectangular main body upper part 8a.
An annular groove 6 is provided between the main body lower part 8b and a flange (not shown) is formed at the lower end of the main body lower part 8b. The main body upper parts 8a, 8a are fixed to waist members 27, 27 attached to the lower front portions of both side surfaces of the base body 20 via support shafts 26, 26. Thereby, the telescopic members 1, 1 can be rotated about the support shafts 26, 26 as fulcrums. Reference numerals 2b and 2b indicate feet portions that are attached to the lower side surfaces of the outer members 2, 2 so as to be freely protrusive and retractable.

The arm members 30, 30 are rotatably attached to the tips of folding members 31, 31 which are foldably formed on the back surface of the base body 20 by means of support shafts 33, 33, and the connecting shafts 30c, It is formed by upper and lower members 30a, 30a, 30b, and 30b that can be freely divided via 30c. Thereby, the annular groove members 30, 30 can be folded onto the back surface of the base body 20 via the folding members 31, 31, or unfolded from this back surface. In addition, in this unfolded state, the arm members 30, 30 can be rotated about the support shafts 33, 33, and the arm members 30, 30
Upper and lower members 30 that can be divided freely via 0c and 30c
Since it is formed of a, 30a, 30b, and 30b, it can also be expanded and contracted in the vertical direction. 32,
Reference numeral 32 indicates a hand portion attached to the tip of the lower members 30b, 30b.

In order to change the form-changing toy B having the above structure from the form of an adhesive tape storage platform to the form of a robot, first, as shown in FIGS. 3a and 3b, the cover member 2 is
2 is raised along the guide grooves 24, 24 of the base body 20 to cover and hide the adhesive tape 21 detachably attached to the upper part of the base body 20. As a result, the head 25 covered by the cover member 22 is exposed. Next, the elastic members 1, 1 fixed to the waist members 27, 27 attached to the front lower part of both sides of the base body 20 via the support shafts 26, 26 are attached using the support shafts 26, 26 as fulcrums. Rotate it to project it forward. As shown in FIG.
After rotating the outer members 2, 2 inwardly by 90 degrees by aligning the rectangular through holes 3, 3 drilled in a, 2a with the annular grooves 6, 6 formed at predetermined positions in the inner members 5, 5. It is moved to the lower part to constitute a robot leg member, and the leg parts 2b, 2b attached to the external members 2, 2 in a retractable manner are made to protrude. This prevents the external members 2, 2 from rotating unintentionally. Further, arm members 30, 3 are rotatably attached to the tips of folding members 31, 31 folded on the back side of the base body 20 via support shafts 33, 33.
0 protrudes in the left-right direction, thereby making it possible to obtain a toy having a robot-like form.

Moreover, when changing from a robot-like form to an adhesive tape storage stand-like form, the rearrangement may be performed in the opposite order to the above.

As mentioned above, by using the telescopic rotation mechanism A in the shape-changing toy in the shape-changing toy B,
When this shape-changing toy B is changed from an adhesive tape storage stand-like form to a robot-like form, the outer members 2, 2 forming the elastic members 1, 1 and the inner member 5,
5 will not rotate except in the annular grooves 6, 6 provided at predetermined positions of the internal members 5, 5.
This makes it possible to reliably maintain that state and prevent the leg from deforming after the shape change, and also to easily rotate the leg.

Note that the telescopic members 1, 1 are not limited to the legs, and may be, for example, the arms. Furthermore, shape-changing toys are not limited to robots.
