Description

[Detailed description of the invention] This invention relates to the limbs of a robot toy.

In robot toys, it is desired that the limbs have various shapes and be able to turn in various directions. However, the limbs of conventional robot toys that have attempted to meet the above requirements have complicated structures and are therefore expensive, making them unsuitable for practical use.

In view of the above points, this idea has a simple structure,
To provide a limb of a robot toy which can be expanded, contracted and rotated arbitrarily and can therefore have free poses.

Next, one embodiment of this invention will be described based on the drawings.

FIG. 1 shows the basic structure of the main parts of the limb according to this invention, in which 1 is a rod, and 2 and 3 are cylinders fitted to both ends of the rod. The rod 1 has stoppers 4 and 5 formed with enlarged diameters at both ends in the longitudinal direction. The cylinders 2 and 3 are opened in the axial direction on one side.

Stroke of each cylinder, i.e. hollow parts 6, 7
The length in the axial direction of the rod 1 is one half of the length of the rod 1, and the cross-sectional shape of the inner surface of the hollow part and the cross-sectional shape of the stopper of the rod are both circular, so that the rod 1 It is rotatable about the axis relative to the cylinders 2 and 3, and the rod can be moved in and out of each cylinder, so that the length between the two cylinders can be freely expanded and contracted.

The drawings following FIG. 2 show an example in which this invention is specifically applied to an upper limb of a robot toy, that is, an arm, and each cylinder preferably has the following structure:
The inner tube 8 and the outer tube 9 are formed in double layers with the inner and outer tubes separated from each other. The inner cylinder 8 forms the hollow parts 6, 7, and as mentioned above, each cylinder 2, 3 is connected to the rod 1.
The rod is rotatable about the axis relative to each cylinder, and the rod is also movable in the longitudinal direction relative to each cylinder and can be held at any position. That is, the length of the rod can be freely expanded or contracted by inserting the rod into or pulling it out from the cylinder.

In order to enable air intake and exhaust from the hollow part within the cylinder when the rod is inserted or removed, small holes (not shown) are provided in the inner cylinder and the outer cylinder to communicate the hollow part with the outside.

By separating the outer cylinder 9 outward from the inner cylinder 8, the outer diameter of the cylinder can be freely set to a size that matches the appearance of the robot toy.
It is possible to have an arbitrary external shape so as to form part of a limb.

In the illustrated example, one cylinder 2 constitutes the upper part of the upper arm connected to the shoulder of the robot toy main body R, and the other cylinder 3 constitutes the lower part of the upper arm. This cylinder 3 is fitted into an upper fitting recess 11 of a lower arm portion 10 formed as a separate member, and is rotatably connected via a hinge 12.

Since the stroke of each cylinder, that is, the length of the hollow part in the axial direction, is approximately half the length of the rod, the length of this limb is set to the second length.
As shown in the figure, shorten to the shortest or third
It can be extended to its maximum length, as shown, or any length in between. Furthermore, since the rod 1 is freely rotatable relative to each cylinder, the arm can be directed in any direction. Figures 4 and 5 illustrate two poses of the robot with arms attached according to this invention.

In the above embodiment, this invention is applied to the upper arm, but this invention can be similarly applied to the lower arm or lower limb body (upper leg, lower leg).

As mentioned above, according to this invention, the limbs of the robot toy can be freely expanded and contracted in the required parts, and can also rotate by any amount, making it possible to change the limbs of the robot into various forms. ,
It is possible to pose freely and perform a wide variety of movements.
