Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD This invention relates to a traveling toy that changes while traveling using power for traveling.

PRIOR ART AND THEIR DISADVANTAGES Recently, various types of traveling toys that change in some way while running have been proposed, but all of them involve adding components other than the components of the traveling toy, for example, components of a robot. The structure is complex, as the additional elements expand to change the form from a running toy to a robot.
I didn't enjoy the changes in pure running toys.

For example, Japanese Patent Application Laid-Open No. 109589/1989. Furthermore, among the forms of traveling toys, one whose external shape changes while traveling is disclosed in Japanese Utility Model Application Publication No. 179191/1983. However, in this case as well, the mounting structure of the variable biasing member, the locking structure of the variable element, and the locking release structure are complicated, resulting in high costs.

Purpose of the Invention The present invention utilizes traveling power and has a simple configuration to cause a projectile to be fired while traveling so that a covering part is flipped up from a base or a pilot housed in a covering part. To provide a perverted running toy in which the running toy itself can be flipped up from an opening provided in a covering part to enjoy unexpected changes in the running toy itself.

Means for Achieving the Objective In order to achieve the above object, the present invention locks the projectile body in an energy storage state within the traveling toy before traveling, and when the toy starts traveling, the rotating shaft of the power unit such as a spring unit or battery-driven motor is activated. The rotation at the time of output releases the locking of the projectile and causes the projectile to project, thereby damaging a covering part such as the body of a traveling toy, or a pilot housed in a covering part,
It is a doll that resembles a driver or coachman, and is made to bounce upward.

Embodiments of the Invention Next, embodiments of the invention will be described with reference to the drawings.

A housing 2 of a power part is mounted on the upper surface of a base 1 of a traveling toy such as a chassis, a protrusion 3 provided at the rear of the housing 2 is fitted into a fitting groove 4 of the base, and a hook is provided with the front part of the housing 2 protruding from the base. It is locked and fixed at 5.

The power section may consist of a motor using a battery and a reduction gear train, but it may also consist of a mainspring and a reduction gear train, as in the illustrated example. and,
A lock release piece 7 is provided protruding from a rotary shaft 6 having a slow rotation speed among the reduction gear train.

This unlocking piece 7 is rotatably attached to the rotating shaft 6 with a constant friction. If a force in the opposite direction is applied, the unlocking piece will be rotated relative to the rotation axis.

To explain an example of the structure for attaching the lock release piece 7 to the rotating shaft, the lock release piece 7 is attached to the third
As shown in the figure and FIG.
b, the bearing part 7a is slightly extended in the axial direction, and a spring ring 8 is fitted around the extended part, so that the spring ring connects the bearing part to the rotating shaft 6.
It is tightened at the top. Alternatively, as shown in FIG. 5, a one-way clutch may be constructed by meshing a gear 6a provided on the rotating shaft 6 with an elastic gear 7c formed within the bearing portion of the unlocking piece 7.

A spring body 9 is rotatably attached to the upper surface of the base 1 so as to spring upward, that is, in a direction away from the base 1. The elastic body in the first embodiment has ribs 10 and 1 protruding from the upper surface of the base 1 to fit the housing 2 of the power unit.
1, one end of which is fitted in the front of the hook 5, and the pin 1 passes through the rib and the fitting part.
2, the flip-up piece 1 is rotatably supported around the pin on the upper surface of the base 1 from a state of lying down to standing upright and being stopped by the hook 5.
3, and a coil spring 14 that is wound around the pin 12 in a notched recess 13a provided at the fitting portion of the flip-up piece, and has both ends locked to the flip-up piece 13.
When the flip-up piece 13 is released, the coil spring 14 causes the flip-up piece to rotate and stand up. The height of the flip-up piece in the upright state is higher than the height of the front part of the covering part 15 such as the body attached to the base part 1.

In addition, a locking groove 16 is formed on the upper surface of the flip-up piece 13 in the folded state, which is slightly inclined rearward and opens opposite the hook 5. 17
is the wheel 19 of the front wheel 18 when the projectile is laid down.
It is a groove formed to escape.

A locking piece 20 is held between the hook 5 of the base portion 1 and the locking groove 16 of the flip-up piece 13 of the projectile body 9 in the fallen state. The locking piece 20 is a member independent from both the base 1 and the elastic body 9, and has a rectangular locking part 20a and a released part 20b extending rearward from the side of the locking part, The projectile 9
When the locking piece 20 is held between the base 1 and the
The tip of the unlocked portion 20b is located on the side surface of the housing 2 of the power unit, within the rotation locus of the unlocking piece 7 as the rotating shaft 6 rotates.

When running this running toy having the above configuration, as shown in FIG. The front part of the flip-up piece 13 is fitted into the groove 16 of the locking part 20a.
The locking piece 20 is fixed to the base 1 with the rear part of the hook 5 in contact with the front surface of the hook 5 and the unlocked part 20b positioned within the rotation locus of the locking release piece 7.

Then, the covering part 15 is fitted onto the upper side of the base part 1,
The rear wheel 2 is connected to the output shaft of the power section, with the projection 22 formed at the rear of the base 1 fitted into the locking hole 21 provided at the rear of the sheath, and the sheath fixed to the base.
3 is pressed against the running surface and moves to the left in FIG. 1 to perform a so-called pullback and store energy in the mainspring of the power section, the rotating shaft 6 is rotated clockwise in FIG. 1. . Rotating shaft 6
When the unlocking piece 7 that rotates with the locking piece 7 hits the releasing part 20b of the locking piece 20, the force applied by the locking piece 20 opposing the locking piece 7 is caused by the force between the locking piece 7 and the rotating shaft 6. Even if the pullback is continued, the locking release piece 7 release portion 20
It is stopped at the position where it hits b.

When the user releases the running toy with energy stored in the spring, the energy is released from the mainspring, the rear wheel 23 rotates clockwise in FIG. 1, and the toy starts running to the right in the figure. At this time, the rotating shaft 6 slowly rotates counterclockwise,
After traveling a certain distance, the locking release piece 7 comes into contact with the lower surface of the release portion 20b of the locking piece 20 and applies an upward force thereto. In this case, since the frictional force of the locking release piece 7 against the rotating shaft 6 is greater than the frictional force of the locking piece 20 against the hook 5, the locking release piece 7 rotates further, causing the locking piece to be released. Push up the portion 20b to release the locking piece 20 from the hook 5. Therefore, as shown by the chain line in FIG.
Since the covering portion 15 suddenly rises, the covering portion 15 is flipped upward by the projectile and the covering portion 15
The rear part of the base part 1 is spaced apart from the rear part of the base part 1.

That is, while the traveling toy is running, the covering portion is suddenly flipped up from the base, and the traveling toy continues to travel as it is.

In the above embodiment, the covering part 15 is removably attached to the base 1, and the covering part 15 is configured to be flipped up from the base by the resilient body 9. However, the covering part is fixed to the base, and the covering part An opening is provided in the front part of the shell, and a doll resembling a pilot or the like is housed in the covering part above the projectile body, and the doll is moved to the It can also be configured to pop out upward from the opening.

Further, in the above embodiment, the elastic body is composed of the hard flip-up piece 13 having one end pivoted to the base, and the coil spring 14 that provides an elastic force to this, but the elastic body is limited to this. Instead, as illustrated in FIG. 7, it is also possible to configure it with a single plate spring 9a. That is, one end of the leaf spring 9a is fitted and fixed into the cavity 24 formed between the rear end of the base 1 and the rear end of the power unit housing 2, and the other end of the leaf spring is fitted into the hole 24 formed between the rear end of the base 1 and the rear end of the power unit housing 2. If the locking piece 20 is locked to the locking portion 20c provided on the top surface and pressed between the locking groove 16a provided on the front top surface of the base 1 and the hook 5, the energy released from the power section 2 will cause the rearward movement. While the wheel 23 rotates and travels, as in the case described above, the rotation of the rotating shaft 6 causes the lock release piece 7 to release the lock release part 2 of the lock piece 20.
By pushing up 0b, the locking piece is released from locking with the base 1 via the hook 5,
The tip of the leaf spring 9a, which is an elastic body, is released, and the elastic body springs up, causing the covering part 15 or the doll housed in the covering part to be thrown up.

Effects of the Invention As described above, according to the present invention, the elastic body attached to the base of the traveling toy so as to exert an elastic force in the direction away from the base of the traveling toy, and the rotating shaft of the power section of the traveling toy. , a lock release piece that protrudes in a direction perpendicular to the rotation axis and is rotatably provided with a constant frictional force between the rotation shaft and the friction between the rotation shaft and the lock release piece. The system is removably locked to the base with a frictional force smaller than the force, and the elastic body is held in a collapsed state on the base, and as the rotating shaft of the power unit rotates at the time of output. Since the locking piece is provided with a locking piece that releases the locking to the base part by the locking release piece and causes the elastic body to spring, the structure is extremely simple, it can be manufactured at low cost, and it can be manufactured easily while traveling. The shape of the running toy changes automatically, or the doll etc. jumps up, and
The locking release piece is provided on the rotating shaft so that it will idle relative to the rotating shaft when it receives a force that exceeds the frictional force between it and the rotating shaft, so there is no need to use the locking release piece when pulling back the traveling toy. This prevents the locking piece from being unlocked.
