〔Example〕

Next, an example in which the movable form-changing toy according to the present invention is applied to a robot traveling toy will be explained based on the drawings.

Figures 1 to 5 show an embodiment of the present invention. A robot running toy 1 according to the present invention has the shape of a robot as a whole, and is generally rotatably supported by a body 2. It is composed of a pair of leg parts 3, 3. The legs 3, 3 can change from a folded state on the trunk 2 as shown in FIG. 1 to an extended state as shown in FIG. 2, and vice versa.

Next, details of each part will be explained.

A protrusion 4 that also serves as the head of the robot is formed at the tip of the body 2, and a driver's seat 6 is provided above the body 2 in which a doll 5 imitating a driver can sit. The protrusion 4 may take the shape of an attack weapon such as a drill, or may take the shape of a missile that can be launched.

On the other hand, left and right arm parts 7, 7 are attached to both sides of the body part 2 so as to be rotatable in the direction shown by the arrow in FIG. As shown in the figure, wheels 8 and 9 are rotatably mounted in a protruding state.

Further, as shown in FIG. 4, a spring unit 10 as a power source is housed inside one side of the body 2. As shown in FIG. As shown in an enlarged view in FIG. 5, this mainspring unit 10 is fixed on a chassis 11 that forms the lower surface of the body 2, and inside thereof there is a mainspring and many gears that interlock with the mainspring. It is accommodated. A shaft 12 is provided at a position near one end of the mainspring unit 10 so as to protrude from both the left and right sides.
The wheels 9 are fixed to both ends of this shaft 12, respectively.

The shaft 12 serves both as a winding shaft for the mainspring housed in the mainspring unit 10 and as a drive shaft for transmitting the rotation force when the mainspring rotates.

Further, an output shaft 14 is provided protruding from the side surface of the other end of the mainspring unit 10. This output shaft 14
is, for example, a mainspring winding shaft, and the rotating force of the mainspring is transmitted through a gear group (not shown) housed in the mainspring unit 10, and the mainspring rotates clockwise in FIGS. 4 and 5. The speed is extremely slow. A cam 15 as a release means is fitted to the output shaft 14 in a frictional contact state.
The cam 15 is in a fitted state in which it rotates together with the shaft 14 unless a large load (a force that prevents rotation) is applied to the cam 15 . A part of the cam 15 has a long diameter portion 1.
5a is formed, and a stepped portion 15b is formed on the counterclockwise side (in FIG. 4) of this long diameter portion 15a.

On the other hand, a bearing portion 16 is protruded near the shaft 14 at the side edge of the chassis 11.
A locking member 17 that locks the leg portion 3 in the folded state is rotatably supported on the locking member 6 via a pin 18 projecting from its lower end.

A hook 19 is formed at the upper end of this locking member 17, and as shown in FIG. It stands out. And hook 1
The upper surface side of the distal end portion of No. 9 is formed in a gently sloped state (the state becomes lower toward the distal end). Further, on the cam 15 side of the locking member 17, a fourth
As shown in the drawings and FIG. 5, a stepped portion 17a that can engage with the stepped portion 15b of the cam 15 is formed. The locking member 17 is shown in FIGS. 4 and 5.
As shown in the figure, a rotational force is applied in the direction of the cam 15 by the spring 20 stretched between the chassis 11 and the end portion of the stepped portion 17a is moved to the fourth position.
As shown in the figure, it is always in sliding contact with the outer periphery of the cam 15.

Therefore, in FIG. 4, the mainspring (not shown) in which the robot traveling toy 1 is housed
If it moves forward (leftward in Figure 4) as it unravels,
The output shaft 14 rotates slowly clockwise, and the cam 15 also rotates clockwise accordingly. As the cam 15 rotates clockwise, the long diameter portion 15a of the cam 15 approaches the locking member 17. Then, before long, the long diameter portion 15a of the cam 15 comes into sliding contact with the locking member 17, whereby the locking member 17 is connected to the spring 2.
The leg portion 3 is rotated counterclockwise against a tension of 0, that is, in a direction to release the lock of the leg portion 3.

On the other hand, when rotating the wheel 9 clockwise in FIG. 4 by moving the robot traveling toy 1 backward, for example, to wind up the mainspring (not shown) housed in the mainspring unit 10, The output shaft 14 and the cam 15 rotate slowly counterclockwise. Then, eventually the stepped portion 15b of the cam 15
comes into contact with the stepped portion 15b of the locking member 17 and its rotation is hindered, so that the cam 15 then engages with the output shaft 14.
The output shaft 14 only rotates counterclockwise. Therefore, the locking member 17 is not rotated by the cam 15 when the mainspring is retracted.

By the way, the left and right legs 3, 3 are fixed to both ends of one shaft 21 so as to always rotate together, and are always rotated in the extending direction by a torsion coil spring 22 wound around the shaft 21. That is, a rotational force is applied in the clockwise direction in FIG. An opening 3a into which a hook 19 is inserted and locked by the hook 19 is formed on one leg 3 side. In addition, protrusions 3 are provided on the heel sides of the left and right legs 3, 3.
b are provided protrudingly, and these protrusions 3b are provided with wheels 2.
3 is rotatably attached.

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

First, twist the left and right legs 3, 3 and attach the coil spring 2.
It is rotated so that it overlaps the upper side of the body part 2 (as if it is folded) against the return force of 2. During this rotation, the edge of the opening 3a comes into contact with the upper inclined portion 19a (FIG. 5) of the locking member 17 in the process of fitting the hook 19 into the opening 3a. Due to the contact pressure of the opening 3a on the inclined part 19a, the locking member 17 resists the tensile force of the spring 20 and rotates slightly in the direction away from the cam 15, and then escapes. It is returned to its original position by the tensile force of the spring 20. During this return process, the tip of the hook 19 engages inside the side edge of the opening 3a. As a result, the legs 3, 3 are held in a folded state toward the body 2, as shown in FIG.

Next, while pressing the wheels 9, 9 which are in contact with the ground in this state, against the floor surface, the robot traveling toy 1 is moved in a direction to wind up the mainspring. When the mainspring is wound in this way, the stepped portion 15b of the cam 15 is engaged with the stepped portion 17a of the locking member 17 as described above.
The legs 3, 3 are kept locked in the folded state by the locking member 17.

In this state, when the hand is released, the shaft 12 is rotated by the rotating force of the wound spring, and the wheels 9 are rotated in the forward direction, so that the robot traveling toy 1 moves forward in its folded state. Further, as the mainspring rotates, the output shaft 14 and the cam 15 also rotate clockwise in FIG.
5a comes into contact with the locking member 17, the locking member 17 resists the tensile force of the spring 20 and moves to the fourth position.
It is rotated counterclockwise in the figure, and the hook 19 comes off from inside the periphery of the opening 3a.

As a result, the legs 3, 3 are torsion coil springs 22
The force causes it to rotate into an extended state as shown in FIGS. 6A to 6C. The torso 2 of these legs 3, 3
Due to the reaction (inertia) caused by the rotation of the toy from the upwardly folded state, the entire robot traveling toy 1 becomes an upright state as shown in FIGS. 3 and 6C. In this state, the robot traveling toy 1 does not travel.

Incidentally, as shown in FIG. 2, even if the legs 3, 3 are in the extended state, the mainspring can be wound and run, but the above-mentioned rising operation is not performed.

As explained above, according to the present invention, the legs are attached to the upper side of the body of the movable form-changing toy in a manner that allows them to be folded freely and are applied with rotational force in a direction in which the toy is always in an extended state. A power source is attached to the body through wheels, and a release means is attached to the output shaft of the power source to release the locking state of the locking member that locks the legs in the folded state above the body. Therefore, when running with the legs folded above the torso, the legs suddenly rotate to extend while running, and the reaction from this rotation can cause the legs to change to an upright position. I can,
It is possible to provide a movable form-changing toy with unprecedented playability and unexpectedness.
