Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a traveling toy with a built-in spring drive device, which uses the drive force of the spring to automatically move a pre-stored parachute. This invention relates to a parachute release device for a traveling toy that can be released into the air and towed.

(Prior Art) Conventionally, for this type of traveling toy, for example,
There is a traveling toy as described in Japanese Utility Model Application Publication No. 60-81594, which is configured to travel in a straight line using a drive device. It is designed to allow you to have fun doing wheelies.

There is also a toy vehicle equipped with a parachute as described in Japanese Patent Application Laid-Open No. 52-96138. This system consists of a vehicle body with multiple rotatable wheels, a removably housed parachute inside the vehicle body, and a parachute that is released from the vehicle body depending on the condition of the vehicle as it travels along the road. The device for releasing the parachute is formed so that when the vehicle body is in a wheelie state, the arm comes into contact with the running surface and the engagement between the arm and the piston is released. When the car body moves from a wheelie state to a horizontal state, the end of the arm comes into contact with the running surface, the engagement between the arm and the car body is released, and the piston is activated by the spring. and a second locking device configured to push out the parachute by force. That is, when the car body enters a wheelie state, the arm of the first locking device contacts the running surface, and then, when the vehicle body becomes horizontal, the arm of the second locking device contacts the running surface. The structure is such that the parachute is released upon contact.

(Problem to be Solved by the Invention) However, when playing with a traveling toy such as the former, simply running in a straight line or wheelie will result in monotonous running, and there is a drawback that it cannot fully satisfy the desires of children who like entertainment. It was hot.

Furthermore, in the case of a toy vehicle with a parachute such as the latter, there is a problem in that the parachute is always released even when it is not desired to release the parachute. Furthermore, the parachute is released by the arms of the first locking device and the second locking device sequentially contacting the running surface.
Depending on the running surface, the arm may not come into contact with the running surface.
There was a risk that the parachute would not be released.
Moreover, since the arm protrudes relatively largely outside the vehicle body, there are disadvantages in that it obstructs running and is easily damaged.

The parachute release device A of the present invention is constructed as described above. Next, an example of its use will be described. First, the parachute discharge device A is opened in an appropriately folded state from the opening 10a located in the open portion 2 of the device case 1. The parachute P is housed in the parachute housing 10, and the parachute housing 10 is attached to the elastic spring 1.
It is made to swing against the elastic force of 5. Then, the locking portion 22 of the locking hook 20 is locked and set in the notched groove portion of the side wall 14 of the parachute container 10. Then, the rear wheel 8 is rotated backward, and the spring of the mainspring drive device 5 is wound up to accumulate and impart an elastic force. At this time, the actuating body 32
The motor rotates together with the driving ratchet 31 until the actuating protrusion 33 comes into contact with the lower surface of the driven part 23 (see FIG. 5). Then, when the spring winding force of the mainspring driving device 5 is released, the rear wheel 8 rotates forward and the traveling toy S runs. At this time, the operating body 32
is rotated by the drive latch 31, and presses the upper surface of the driven portion 23 of the locking hook 20 with the operating protrusion 33, causing the locking hook 20 to swing against the elastic force of the elastic spring 25. (See Figure 6). Then,
The parachute housing body 10 is rapidly swung by the elastic force of the resilient spring 15, and the parachute P inside the parachute housing body 10 is pushed out toward the front wall 11, and the opening 10a and the opening 2 After that, it is released to the rear of the running toy S. The released parachute P is opened by the wind pressure on the parachute main body P1, and is towed by the traveling toy S while floating in the air (see FIGS. 1 and 2).
Note that the parachute P is released after the traveling toy S has traveled for a certain amount of time. That is, when the traveling toy S travels and the parachute P is released, the operating protrusion 33 of the operating body 32 engages the locking hook 2.
The time difference (when the working protrusion 33 A time difference (difference in time during approximately one rotation) occurs.

Further, it is also possible to prevent the release of the parachute P by rotating the switching knob 40.

(Effect of the invention) Therefore, the parachute release device A of the present invention has the following effects:
In a traveling toy S that runs using a built-in spring drive device 5 as power, a parachute container 1 is provided at the rear of the device case 1 with an opening 10a.
0 is attached so as to be swingable, and the elastic force of the spring 15 is applied to the parachute housing body 10 along the swinging direction, and the parachute is housed in a state in which the elastic force is accumulated and applied to the spring 15. The locking hook 20, which is detachably locked to the body 10, is connected to the locking release mechanism 3.
The unlocking mechanism 30 is connected to the mainspring drive device 5 through It has an actuating body 32 that is rotatably mounted and rotated by a drive latch 31, and is formed by protruding from the actuating body 32 an actuating protrusion 33 that can press the locking hook 20. , the locking state of the locking hook 20 to the parachute housing body 10 is released, the parachute housing body 10 is swung by the elastic spring 15, and the parachute housing body 10 is
Since the inner parachute P is formed so as to be ejected from the opening 10a to the outside of the traveling toy S, when the traveling toy S has traveled to a certain extent by the spring drive device 5, the parachute P is released from the parachute housing 10 of the locking hook 20. The locked state of the parachute container 1 is reliably released, the parachute container 10 swings, and the parachute container 1
A parachute P previously housed inside the traveling toy S can be reliably released to the outside of the traveling toy S, and the parachute P can be towed. Moreover, the configuration of the parachute release device A itself is simple, suitable for mass production, and can be provided at low cost.In addition, the parachute release device A can be made smaller, more compact, lighter, and more robust. 5 is ideal as a parachute release device A for a relatively small running toy S.

Further, the unlocking mechanism 30 is connected to a driving ratchet 31 which is fixed to the main gear shaft 6 fixed to the base end of the mainspring of the mainspring drive device 5, and a driving ratchet 31 which is rotatably attached to the main gear shaft 6. Since the actuating body 32 is provided with an actuating protrusion 33 that can press the locking hook 20, the locking hook 20 can be securely attached to the main gear shaft 6 of the mainspring drive device 5. The locking hook 20 can be reliably pressed and operated by the operating protrusion 33 of the operating body 32 when the spring retracting force of the mainspring driving device 5 is released.

In particular, the switching knob 40 provided with a stopper piece 42 is rotatably provided near the parachute housing 10, and the stopper piece 42 of the switching knob 40 is configured to be detachably engaged with the parachute housing 10. Even if the locking state of the locking hook 20 to the parachute housing body 10 is released by rotating the switching knob 40, the stopper piece 42 remains locked to the parachute housing body 10, and the bullet is not released. It is now possible to reliably and easily prevent the parachute housing body 10 from swinging due to the elastic force of the spring 15, and it is easy to enjoy the parachute P by releasing it, or enjoy it without releasing the parachute P. This allows you to easily play interesting games.
