Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a toy that can climb not only steps and steep slopes, but also vertical surfaces.

(Prior Art) Conventional running toys move forward and backward using the rotational force of wheels or the rotation of endless tracks.

(Technical Issue) Therefore, it is difficult for conventional toys to climb over large steps that exceed the radius of the wheels. The degree of inclination that can be climbed is also determined by frictional force and the height of the center of gravity. Therefore, the movement mode of conventional toys is simple and lacks surprises.

The purpose of the present invention is to solve the above-mentioned problems and provide a climbing toy that can move freely by climbing not only steps and steep slopes but also vertical surfaces.

(Technical Means) The purpose is to provide at least one rotating wheel 1 that moves while adhering to the moving surface due to adhesiveness, a drive source 2 that applies rotational force to the rotating wheel 1, and a pressurizing the rotating wheel 1 to the moving surface. This is achieved by a configuration comprising a branch 3 that performs the action. In particular, since the entire structure is made lightweight to the extent that it is less than the adhesion and movement force of the rotary wheel 1, vertical movement is facilitated.

It is desired that the rotating wheel 1 is lightweight, has high elasticity, and has a tread surface with appropriate adhesion.

This adhesive force is necessary for the toy to move on steep slopes and vertical surfaces, and the overall balance is determined so as not to impair the adhesive moving force.

(Example) This will be explained with reference to the drawings.

The rotating wheel 1 is composed of a single member having a wide tread surface, and is made of a material having high elasticity and adhesiveness. As this highly elastic and highly adhesive substance, for example, styrene ethylene butylene styrene block copolymer (SEBS) can be used. It is also possible to use a material obtained by crosslinking a high boiling point oil substance and a soluble rubber substance to impart high elasticity and adhesiveness. Of course, the rotating wheel 1 need not be made of a single member, but may have a structure in which a highly elastic and highly adhesive substance is provided on the outer peripheral surface.

The illustrated rotating wheel 1 has a tread shape in which a semi-cylindrical protrusion 5 is arranged in parallel with the rotating wheel.
The concave portion 6 acts to transmit a high adhesion force intermittently to the moving surfaces S and S' (see FIG. 6).

The rotating ring 1 is attached to the shaft portion 8 of the lightweight tubular body 4 in the shape of a hollow tube from the outside, and rotates together with the tubular body 4. 7 is a shaft hole for fitting. The tubular body 4 is arranged horizontally, and a hook 9 for hanging one end of the rubber strip serving as the drive source 2 is attached to one end of the tubular body 4 by a projection 9a so as not to rotate relative to the tubular body 4. Numeral 10 is a notch for hanging rubber, 11 is a circular tube portion for passing the rubber system, and 12 and 13 are flanges at both ends of the tube body 4, which are formed in a tapered shape (FIG. 4).

The other end of the rubber strip is hung between the notches 15 of the rotary catch 14 which is rotatably fitted loosely into the tube body 4. A branch piece 3 extending in the radial direction is integrally protruded on the hook 14, and when the branch piece 3 is turned to wrap the rubber strip and the stored force is released, the branch piece 3 and the tube body 4 are separated. can be rotated in opposite directions, the tube body 4 side supports the moving force of the rotary wheel 1, and the support piece 3 side exerts the effect of pressing the rotary wheel 1 against the moving surface S. A spacer washer 16 may be interposed between the rotation stopper 14 and the tube body 4 to adjust the frictional force.

Further, the rear end 17 of the branch piece 3 is bent so that the tail curvature 3a reaches a line passing through the center of the length of the tube body 4, thereby improving running balance.

With the above configuration, the toy of the present invention is self-propelled, but if the exterior 20 is attached to it, the toy becomes more complete. The exterior 20 can be shaped like an animal, an insect, or any other shape. In the case of the structure shown in FIG. It can be fitted and installed.
In addition to the above-mentioned rubber strip, a spring or an electric motor can of course be used as the driving source.

7 to 9 show a second embodiment, in which the shape and structure have been modified so that it can be handled as a fully completed toy without the need for an exterior body.

The branch piece 3 has a crank-shaped planar shape so that the rear part 3b of the branch line coincides with the center line of the tube body 4, and a dorsal fin 3c like the vertical tail of an airplane is provided at the rear end to protrude. , a sticker 3d can be pasted on both sides, a tail sled 3a is provided at the lower rear end, and the weight of the entire branch is reduced by a lightening hole 3e. 3f indicates a reinforcing piece.

The rotation side latch 14 from which the support piece 3 is protruded includes:
A notch 15 for passing the rubber strip is provided at only one side on the side so as to reach the center hole 21, and a hooking piece 22 is provided to protrude toward the center hole 21 from the opposite side of the notch 15. The fixed-side hook 9 is provided integrally with the flange 12, and has a cantilevered hook 23 similar to the rotating side, and the notch 10 of the tube body 4 is continuous therewith. Other configurations may be the same as those of the embodiment.

(Function) To move the proposed toy, wrap the rubber strip around the support piece 3 as described above, and then move the rotary wheel 1 onto the horizontal moving surface S.
, and the protrusion 5 sequentially contacts the moving surface S and moves forward.

The rotating wheel 1 moves while the protrusion 5 adheres to the moving surface S, so even if there is a step P on the way, it rides on it almost unchanged.
Since the presser foot cooperates with the moving surface S, the movement continues reliably.

The situation is exactly the same when reaching the vertical movement surface S', and the rotating wheel 1 grips the wall surface by its adhesive force and steadily climbs vertically.

Note that the flanges 12 and 13 formed in a tapered shape
, even if the toy is tilted at the step P, its movement is not hindered.

(Effect) Therefore, according to the present invention, not only steps and steep slopes but also
Since it can be made to climb even on vertical surfaces, it is possible to obtain the effect of exhibiting an unexpected form of movement, making it possible to provide an extremely novel and unique toy.
