Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a movable shape-changing toy, and more specifically, the toy runs with the legs folded above the torso, and during the running process, the legs suddenly move. The present invention relates to a movable shape-changing toy that extends in a straight state and stands up due to the reaction force of its legs.

[Prior art]

The present applicant proposed in Utility Model Application No. 58-7545 that the vehicle travels with the legs folded above the torso as described above, and during the traveling process, the folded portions suddenly straighten out. The application has been filed for a movable, shape-changing toy that can extend and change into an upright state.

This toy travels in a folded state, and as it travels, the folded part suddenly extends (extends to a straight state) and stands up due to the reaction force, making it an unprecedented toy. However, this movement of standing up can only be performed under concentrated reaction force, and there is a problem that stable standing cannot be maintained unless the reaction force is within a certain range. There was still room for improvement.

[Purpose of this invention]

The present invention was developed in view of the above circumstances, and it is possible to concentrate the reaction force for standing up, and furthermore, it is possible to adjust this reaction force in multiple stages, thereby making it possible to stand up reliably and stably. The purpose of the present invention is to provide a robot toy that can stand up.

[Structure of the idea]

To achieve the above object, the movable form-changing toy of the present invention has a body that is movable by wheels connected to a power source, and is foldable on the upper side of the body. A leg part that stands up together with the torso due to the reaction when it rotates and extends from the folded state under constant rotational force in the extension direction, and the leg part is folded above the torso. and a release means attached to the output shaft of the power source to release the locking state of the leg by the locking member when the torso is traveling. The movable shape-changing toy is characterized in that a standing-up promoting member having a predetermined protrusion is provided at a portion of the torso that becomes a fulcrum when standing up. Note that the amount of protrusion of the standing-up promoting member may be adjustable.

[Example of idea]

Embodiments of the present invention will be described below based on the drawings.

Figure 1 and the following show an embodiment in which the present invention is applied to a toy in the form of a robot. Robot running toy 1 as a movable shape-changing toy according to the present invention.
has the shape of a robot toy as a whole in an extended state, and is generally composed of a body part 2 and a pair of legs 3, 3 rotatably supported on the body part 2.

The toy 1 can change from a folded state as shown in FIG. 1 to an extended state as shown in FIG. 2, and vice versa.

Next, details of each part of this robot traveling toy 1 will be explained.

A protrusion 4 that also serves as the head of the robot is formed at the upper end of the body 2, and arms 5, 5 are rotatably attached to the left and right sides.

A pair of left and right running wheels 6, 6 are attached to the back of the body 2 and near the shoulders so as to protrude toward the back (FIG. 3). However, the number of wheels is not limited.

In addition, as shown in FIGS. 3 and 4, the body 2
A pair of protrusions 7, 7 serving as regulating means are integrally formed in the lower half of the leg portions 3, 3 so as to overlap with the back sides of the legs 3, 3.

On the other hand, as shown in FIG. 4, a spring unit 8 is housed in the body 2 as a power source.

This mainspring unit 8 (shown enlarged in FIG. 5) is fixed to the back side of the body 2, and houses a mainspring and a group of gears interlocking with the mainspring.

At a position close to one end of the mainspring unit 8, a shaft 9 projects on both left and right sides, and the wheels 6 are fixed to both ends of the shaft 9, respectively.

Further, a cam 11 is fixed to the output shaft 10 of the spring unit 8 as a release means.

This cam 11 has a claw 11a.

On the other hand, a lever 3 as a locking member is attached to the outside of the end of the mainspring unit 8 on the shaft 9 side via a shaft 12.
3 is rotatably supported.

This lever 13 is formed in a T-shape, and a hook 14a is formed at the tip of the vertical portion 14.

A hook 15a is also formed at the tip of the horizontal portion 15.

The tip of the vertical portion 14 of the lever 13 faces outward from an opening 2a formed on one side of the body 2, for example, on the left side of the chest (Figs. 2 and 4).
figure).

Further, the hook 15a at the tip of the horizontal portion 15 is in a position where it can come into contact with the claw 11a of the cam 11 (the fourth
figure).

A spring 16 is elastically mounted between the horizontal portion 15 of the lever 13 and the inner wall of the body, and applies a rotational force to the lever 13 in the clockwise direction in FIG.

Therefore, the tip of the horizontal portion 15 is in constant contact with the cam 11, and when the cam 11 rotates clockwise in FIG. 4 during running as will be described later, the claw 1
The arcuate portion of 1a engages with the hook 15a, and the lever 1

from the legs as described below.

The cam 11 is fitted to the output shaft 10 in a frictionally coupled state, and the cam 11 rotates together with the shaft 10 unless an external force is applied to the cam 11 to prevent rotation.

On the other hand, an opening 3a is formed in the leg 3 on the side from which the hook 14a protrudes among the legs 3, 3, and when the legs 3, 3 are folded as described later, the hook 14a is opened. 14a is fitted into this opening 3a, and the hook 14a is engaged with the peripheral edge of the opening 3a to maintain the folded state of the legs 3, 3.

Further, a wheel 17 is rotatably supported on the toe side of the legs 3, 3 at a position where it can come into contact with the floor surface.

The trunk 2 and the legs 3, 3 are foldable (rotatable) via a shaft 18 at the lower end of the front of the trunk.
is connected to. In addition, a torsion coil spring (not shown) is wound around the shaft 18, and this coil spring applies rotational force in the direction in which the body 2 and the legs 3 are always in an extended state. There is.

By the way, as shown in FIG. 6, a notch 19 is formed at the rear of the protrusion 4 which also serves as the head.
A substantially diamond-shaped standing-up promotion member 20 is rotatably supported within the notch 19 via a shaft 19b.

This standing-up promoting member 20 is rotatably supported by a shaft 19b at one end on a shorter diagonal line, and has a recess 20 on its back side as shown by a dotted line.
a, 20b are formed.

A protrusion 19a formed on the lower surface of the notch 19 is fitted into the recesses 20a, 20b.

The sides 21 and 22 protruding from the protrusion 4 of the erection promoting member 20 as described above have a distance l ₁ from the axis 19b,
l ₂ (Figure 6) is different and l ₁ > l ₂ .

Therefore, as shown in FIG. 7, the standing up promoting member 20 is rotated counterclockwise as shown in FIG.
2 protrudes, the amount of protrusion of the standing promotion member 20 is small, and when the side 21 protrudes, the amount of protrusion increases.

This state is shown in FIGS. 8A and 8B.

In the case of FIG. 8A, the distance a between the side edge 22 and the floor surface is large when the side edge 22 is protruding, and the distance a between the side edge 22 and the floor surface is large in the case of FIG.
The distance a′ from the floor is small when it is projected.

Next, the operation of this embodiment configured as above will be explained.

First, the legs 3, 3 are folded (rotated) so as to overlap the upper side of the body 2, against the force of a torsion coil spring (not shown) about the shaft 18.

Then, the hook 14a of the lever 13 fits into the opening 3a formed on the leg 3 side (FIG. 4).

At this time, the hook 14a hits the side edge of the opening 3a and is rotated counterclockwise in FIG. 4 against the elastic force of the spring 16, passing over the side edge of the opening 3a and moving inside the side edge. It is hooked (Figure 4).

In this state, the legs 3, 3 maintain their folded state against the force of a torsion coil spring (not shown), and as shown in FIG. The projecting pieces 7, 7 integrated with 2 are a running toy with the projecting pieces 7 facing forward.

At this time, the wheels 6, 6 are in contact with the ground.

In this state, when the wheels 6, 6 are pressed against the floor surface and pulled rearward, the mainspring is wound through the shafts 9 of the wheels 6, 6.

At this time, the output shaft 10, which is a mainspring shaft, is also rotated clockwise in FIG. 4, and the cam 11 is rotated in the same direction. Then, the facing portion of the pawl 11a eventually engages with the hook 15a, but the cam 11 is connected to the output shaft 10.
Only the output shaft 10 is rotated clockwise while maintaining the engaged state because it is frictionally coupled to the
The cam 11 continues to slip and the mainspring is wound up.

If you release your hand in this state, the mainspring will begin to unwind.

The wheels 6, 6 are therefore rotated and the toy begins to travel.

Eventually, as the output shaft 10, which is a spring shaft, rotates counterclockwise in FIG. The hook 14 is rotated counterclockwise against the elastic force of the spring 16.
a separates from the side edge of the opening 3a.

Then, the legs 3, 3 suddenly try to return to the straightened state due to the force of a torsion coil spring (not shown) wound around the shaft 18 that connects the legs 3, 3 and the body 2. .

Of course, the force of the torsion coil spring also acts on the body 2 side, and they both try to return to the straightened state.

As a result, the standing-up promotion member 20 protruding from the rear of the protrusion 4 is hit against the floor surface, and due to the action of centrifugal force when the legs 3, 3 extend, a rotational moment is generated around the promotion member 20 as a fulcrum, which causes the robot to move. The toy in this state reversely rotates in the air and lands with the lower surfaces of the legs 3, 3 facing downward.

Note that when the robot lands, the momentum from the rotation remains, so if the wheels 17 are provided at the tips of the legs 3, 3, the robot starts running while standing.

By doing this, the momentum in the standing state is converted into a force in the direction in which the robot moves forward, so stability upon landing can be measured and the robot will land reliably.

FIG. 9 shows a state in which the vehicle changes shape while traveling in this manner.

By the way, if the standing-up promoting member 20 is rotated to change the distance between it and the floor as shown in FIGS. 8A and 8B, the force with which the standing-up promoting member 20 hits the floor changes, and as a result, the standing Since the climbing momentum also changes, it is possible to change the standing state.

[Effect of idea]

The movable form-changing toy according to the present invention is provided with a standing promotion member having a required amount of protrusion at the part that serves as a fulcrum when the torso stands up, so that a concentrated reaction force for standing up can be obtained and it can stand up reliably. . Furthermore, if the amount of protrusion of the standing-up promoting member is made adjustable, a stable reaction force for standing up can be obtained by adjusting the amount of protruding.
