Description

[Detailed description of the invention] (Industrial field of application and purpose of the invention) The present invention relates to a robot toy, specifically a robot toy in which the lower leg and the foot are connected via a connecting member. It is an object of the present invention to provide a robot toy in which the lower leg part and the foot part can swing back and forth, and the joint members move smoothly.

(Means for achieving the object) In order to achieve the above object, the robot toy according to the present invention is a robot toy in which the lower leg and the foot are connected via a connecting member, and which meets the following requirements. It is characterized by being prepared.

(a) The foot part shall have a two-part structure, be box-shaped, and have a circular opening at the top.

(b) The connecting member is an inverted T made from the horizontal bottom piece and the vertical piece.
Shaped in the shape of a letter, with shafts protruding horizontally on both sides of the vertical piece.

(c) The connecting member is provided within the foot, and the bottom piece is fitted into receiving portions formed on the left and right inner walls of the foot.

(d) A swollen protrusion having a spherical outer surface is formed at the lower part of the crus, and the swollen protrusion is pivotally attached to the axis of the connecting member so as to be swingable back and forth.

(E) The above-mentioned bulge protrudes from the circular opening of the above-mentioned foot.

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

FIG. 1 is an overall view of a robot toy, and a leg 1 of the robot toy is rotatably supported by an upper thigh part 2 and a shaft part 3 at the tip of the upper thigh part 2, and has an outer surface at the tip. It is composed of a lower leg part 4 having a spherical protrusion 5, and a box-shaped foot part 6 connected to the lower leg part 4 via a connecting member 9, which will be described later.

The lower leg part 4 has a vertically divided structure into left and right halves, and as shown in FIG.
A bearing part 10a is formed to engage with the shaft part 3 formed protrudingly inside the holder, a swollen protrusion 5 is integrally formed at the lower part, and a receiving part 8 is formed inside the swollen protrusion 5.
A bearing member 13 made of polypropylene or the like is fitted into the receiving portion 8 . Furthermore, a notch groove 5a is formed in the lower end of the swollen protrusion 5 in the front-rear direction. The two halves of the lower leg portion 4 are joined by inserting the boss 7a formed on one side into the fitting hole 7b on the other side.

Next, as shown in FIGS. 2 and 3, the lower leg portion 4 is connected to the foot portion via a connecting member 9 so as to be swingable back and forth.

That is, the connecting member 9 is formed into an inverted T-shape from a horizontal bottom piece 9a and a vertical piece 9b.
A shaft 9c is provided horizontally protruding from both sides of b, and a bearing member 13 is fitted onto the shaft 9c. When the two halves of the lower leg part 4 are joined together, the shaft 9c of the connecting member 9 is connected to the bearing member 13 and the right and left inner receiving parts 8 of the swelling part 5 of the lower leg part 4.
It is pivoted to a. Thereby, the expanded protrusion 5 can swing back and forth with respect to the connecting member 9 within the range of the notch groove 5a.

Next, the box-shaped foot part 6, which is assembled to the expanded protrusion 5 and the connecting member 9 of the completed lower leg part 4, has a left and right halves, and a receiving part 6a is formed on each inner wall, and the upper part A semicircular notch is formed in the. Also, one of the butt end faces has a boss 6.
c. A fitting hole 6d is formed on the other side, and the leg section 6 is constructed by fitting the two together. At this time, a circular opening 6b is formed in the upper surface of the leg section 6. Further, a connecting member 9 is provided within the foot portion 6, and its bottom piece 9a is fitted and fixed to the left and right receiving portions 6a of the foot portion 6 divided into two. Thereby, the lower leg part 4, the connecting member 9, and the foot part 6 are connected, and the upper part of the swelling part 5 protrudes from the circular opening 6b of the foot part 6.

In the above configuration, the swelling part 5 of the lower leg part 4 is connected to the foot part 6 via the connecting member 9 so as to be swingable in the front-rear direction. During rocking, the swelling protrusion 5 moves within the opening 6b, but since the outer surface of the swelling protrusion 5 is formed into a spherical shape, even when the crus 4 is rocked back and forth, the swelling does not occur. There is no large gap between the outer peripheral surface of the protrusion 5 and the circular opening 6b, and the robot toy can move very smoothly.

(Effects of the invention) As explained in detail above, according to the robot toy according to the invention, the lower legs and feet can swing back and forth, improving the stability and smoothness of the robot toy's walking. In addition, the connecting member is provided inside the foot and is not exposed to the outside, so it looks good, and since the outer surface of the swelling part is formed into a spherical shape, even if the lower leg swings, the connecting member has a good appearance. The gap between the outer surface of the swelling part and the circular opening of the foot can be kept small, and the movement of the robot toy, such as walking, can be made smoother.

In addition, since the connecting structure of the present invention does not connect the lower leg and the foot using a spherical connecting member, the dimensional accuracy between the outer surface of the swelling part and the circular opening of the foot is will not be required.
