Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a joint structure between components for transmitting power in a transformable toy that transforms between two or more forms.

[Technical Problem] The present invention aims to provide a joint structure for a deformable toy that is made up of a plurality of structures and is capable of automatically maintaining a constant state of connection between these structures. be.

[Solution] In order to achieve the above technical problem, the joint structure in the transformable toy according to the present invention is a deformation that can be changed between two or more forms by expanding or assembling a plurality of connected structures. A joint structure of the above structure for transmitting power in a toy,
A pair of joint tools are pivotally supported facing the outer surfaces of the two structures to be connected, one of the joint tools is provided with a plurality of protrusions having a non-axially symmetrical shape, and the other is provided with a plurality of protrusions corresponding to the above-mentioned protrusions. A plurality of recesses are provided which have a non-axially symmetrical shape and allow only a fixed state of engagement with the convex portion, and at least one of the joint tools is attached to the structure by being urged to move forward and backward along the axial direction. It is something.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.
This is an enlarged example of the application to a transformable toy that changes between two completely different forms, a city and a dinosaur, as shown in Figure 2 A, B, C, and D. For convenience of explanation, we will first explain Figure 2 A, B, C, and D. The deformed toy shown in the figure includes a drive device D, a power source E, a built-in center body 1, and a center body 1 rotatably attached to the front end of the center body 1. Building area 2, left and right urban areas 3, 3 rotatably attached to the sides of the central body 1, these left and right urban areas 3, 3
The left and right projecting street sections 4, 4 are rotatably connected to each other.
The urban form shown in Figure 2 (a) is formed by using these as a constituent body. From this state, as shown by the arrows in Figure 2 A and B,
Fold the overhanging street portions 4, 4 in half to form leg portions 5, 5.
Then, the building area 2 is reversed to reveal the head 6, and the left and right urban areas 3, 3 are brought together with the center body 1 in between, and are attracted to each other by a plurality of magnets 7 to form a body part 8. The dinosaur form is shown in Figure 2 C and D.

Here, a joint 10 provided at the end of the output shaft 9 of the drive device D is exposed to both side surfaces 1a of the center body 1 (only one side is shown in FIG. 1). On the other hand, joints 11 are also exposed at corresponding positions on the upper surface of the center part 3, and when the center part 3 is rotated and the center body 1 is sandwiched from left and right when forming the body, these two joints 10 and 11 fit together. Thus, the driving force of the driving device D can be transmitted to the leg portion 5.

As shown in detail in FIG. 4, the joint 10 is a substantially cylindrical component, and has fan-shaped convex portions 10a and 10b that are not axially symmetrical and have different opening angles on the end surface. Also, joint 11 is also the same as joint 10 above.
Similarly, it is a substantially cylindrical component, and fan-shaped recesses 11a and 11b with different opening angles, which are not axially symmetrical, are formed on the end face. Among these, the convex portion 10a with a small angle and the concave portion 11b can be closely fitted together, while the convex portion 10b with a large angle and the concave portion 11b can be closely fitted together.
The angles of each sector are made to correspond. Therefore, the joints 10 and 11 cannot be fitted unless the projections and recesses are matched pair by pair as described above.

The drive device D includes a motor 1 as shown in FIG.
2, a gear group 13, and an output shaft 9 are housed in a case 14, and joints 10 are attached to both ends of the output shaft 9 via springs 15. That is, the joint 10 is inserted into the output shaft 9 so as to be movable forward and backward along the axial direction of the output shaft 9, and when it receives a shock from the outside, it is retracted into the case 14 to absorb the shock.

The joints 10 and 11 are combined when performing the above-mentioned shape change, but at this time, the joint 10 of the central body 1 and the joint 11 of the urban area 3 are not firmly connected. be. In this case, since the joint 10 is attached to the output shaft 9 via a spring 15, if the uneven engagement is not performed properly, the joint 10 will be drawn into the case 14, and even if the motor 12 rotates, it will be in a state of idle rotation. , no driving force is transmitted to the leg portions 5. However, when the output shaft 9 rotates,
Since joint 10 also rotates,
After a short period of time, the convex portion 10a and the concave portion 11a, the convex portion 10b and the concave portion 11b of both of them fit into each other, and the driving force is transmitted in a normal state.

Then, as described above, the convex portions 10a, 10b
Since the concave portions 11a and 11b have a pair of opening angles, the convex portion 10 with a large opening angle
A cannot enter into the recess 10b having a small opening angle, and a constant combination is always obtained.

Furthermore, as described above, the leg portion 5 (overhanging street portion 4) is formed by integrating the two halves 5a, 5b, but the means for connecting the two halves 5a, 5b may also be used. The same structure as joints 10 and 11 is adopted. That is, an eccentric pin 16 attached to the joint 11 is made to protrude into one half body 5a, and a lock pin 17 attached to the outside of the eccentric pin passes through the other half body 5b, and is engaged therewith. . And these eccentric pin 16 and lock pin 1
The above-mentioned uneven shape is formed on the end face of 7, so that it can similarly exhibit a connected state. Here, reference numeral 18 in the figure is a spring, which is inserted into the eccentric pin 16 side, and presses one half body 5a against the other half body 5b side, so that rotation can be transmitted smoothly. .

Note that the joints, dimensions, shapes, etc. used in the joint structure according to the present invention are not limited to the illustrated examples, and it goes without saying that various angles, heights, etc. of the uneven portions can be adopted.

[Effects] Since the present invention is as described above, extremely smooth power transmission can be realized by employing the joints to transmit the power of each component in the deformable toy. When used in objects that require the legs to be moved alternately from side to side, such as moving deformed toys, any misalignment of the joints when assembled will be automatically corrected.
In addition, a very desirable effect as a toy is obtained in that the state is always kept constant.
