Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a connection system that allows a power source and a plurality of mounted running toys to be automatically disconnected from each other and run separately. This invention relates to a traveling toy that runs separately.

(Prior Art and its Problems) Conventionally, there have been running toys that can connect a plurality of running toys equipped with a power source and run them as one. However, in order to change the form of this traveling toy from a connected state to a separated state, it was necessary to once stop traveling and then manually perform a separating operation. Furthermore, in order to facilitate the connected running, it was necessary to set the running speed of each running toy to be the same. Conventional traveling toys that require such manual separation operations have the disadvantage of being uninteresting and easily boring.

(Object of the Invention) This invention was developed in view of the above circumstances, and it is possible to connect a plurality of running toys that can run using their own power source to form a single running toy, or It is an object of the present invention to propose a traveling toy that can be connected and separated and can be automatically released and run separately in different directions or in the same direction, and in which at least one of the traveling toys does not waste power during connected traveling. purpose.

(Means for Achieving the Object) In order to achieve the above object, the traveling toy that connects and runs separately according to the present invention includes a first traveling toy body and a second traveling toy body that have the following requirements. It is characterized by having.

(a) The first traveling toy concrete and the second traveling toy concrete are:
(b) The driving wheels of the second traveling toy body connected to the first traveling toy body are in a floating state from the running surface at the time of connection. (c) The first traveling toy body is provided with a disconnection mechanism that separates the permanent magnet and the magnetic body in conjunction with its drive wheels. (d) The second traveling toy body (E) One end of the switch member, which is swingable and has a dry shape, is provided at a position lower than the drive wheel. (E) One end of the switch member is formed on the drive wheel of the second traveling toy. It is removably provided in the locking part, and is formed so that when the second running toy touches the ground and the switch member swings, the lock with the locking part is released (effect of the invention). (Effects) As described above, according to the traveling toy that connects and runs separately according to the present invention, a plurality of traveling toys that can travel by their own power source are connected to form a single traveling toy. In the connected state, the drive wheels of the second traveling toy are in a floating state, and idling of the drive wheels is prevented by the engagement between the rod-shaped switch member and the ratchet. After that, when the first traveling toy body runs and the coupling state release mechanism is activated in conjunction with its drive wheels, the connection between the permanent magnet and the magnetic body is released, and the second traveling toy body is separated and grounded. do. At this time, the switch member swings and is disengaged from the ratchet, so the drive wheels of the second traveling toy rotate and the second traveling toy starts moving. Therefore, it is possible to obtain a traveling toy that has unprecedented and interesting movements.

(Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1a, b, c, d, and e show a running toy that connects and separates and runs according to an embodiment of the present invention. This traveling toy 1 is composed of a first traveling toy body 2 and a second traveling toy body 3, which are mutually independent traveling toys. Each traveling toy concrete 2 and 3 has bodies 5 and 6
and a wheel 7 supported by each body 5, 6,
8, and a power source (not shown in FIGS. 2a and 2b) such as a mainspring mounted on each body 5, 6. As this power source, for example, a known pullback type spring unit is used,
By rotating a drive shaft having a drive wheel, the mainspring is wound up and power is stored.

A storage space 10 for storing the second traveling toy concrete 3 is formed in the front part of the first traveling toy concrete 2,
A projecting portion 12 that can move forward and backward is provided on the upper part of the rear wall 11 of the space 10, and a permanent magnet 13 is fixed to the lower surface of the projecting portion 12.

Next, as shown in FIG. 2a and b, the overhanging portion 1
2 is integrally connected to the front of a movable base 14 which is provided on the first traveling toy body 2 so as to be movable in the front and back direction, and a locking body 15 is provided on the side of the movable base 14 so as to face rearward. It is arranged. The movable base 14 is always urged forward (in the connection direction) by a spring 18 provided between a protrusion 17 provided on its upper surface and the inner wall of the body 5 (see Figure 2a). ).

Next, reference numeral 20 is a power source, and this power source 2
A cam 22 is fixed to a rotating shaft 21 protruding from the side of 0, and when the power source 20 rotates in the forward direction, the cam 22 also rotates in the direction of the arrow to move the locking body 15 backward against the spring 18. It is configured to be pulled back in the direction of disconnection. When the locking body 15 moves rearward, the movable base 14 also moves rearward. This constitutes a separation mechanism in a connected state with the second traveling toy concrete 3, which will be described later.

3a and 3b show the suspension structure of the rear wheel 7a with respect to the chassis 25 in the first traveling toy concrete 2. FIG. A connecting member 25a is supported on the chassis 25 so as to be able to move up and down, and this connecting member 25a pivotally supports the rear wheel 7a at its rear end and is constantly pressed downward by a spring 26 whose upper end is supported by the body 5. has been done. Also,
The body 5 is also attached to the vehicle chassis by a spring 26 so as to be elastically movable up and down. When the body 5 is pushed downward against the spring 26, the rear wheel 7a is configured to be able to rotate downward together with the connecting member 25a.

The second traveling toy body 3 has a magnetic body 30 on the rear upper surface.
This magnetic body 30 has a second traveling toy body 26
By being magnetically attracted to the permanent magnet 13, the two traveling toy bodies 2 and 3 are brought into a connected state. When the above-mentioned release mechanism is activated and the movable base 14 of the first traveling toy concrete 2 moves backward, the permanent magnet 13 and the magnetic body 30 are separated, so that the first traveling toy concrete 2 The second traveling toy concrete 3 is also separated.

In addition, when the magnetic body 30 magnetically attaches to the magnetic body 13 when the first traveling toy body 2 is in the connected position shown in FIG. 2a, the rear part of the body of the second traveling toy body 3 becomes floating, The driving wheel 8a is configured to be in a non-ground state.

Further, the second traveling toy body 3 has a storage force holding and releasing mechanism 31 as shown in FIG. This stored force holding and releasing mechanism 31 includes a rod-shaped switch member 33 that is swingably supported at one end by, for example, a vehicle chassis 32 and has a locking portion 33a and a pressing portion 33b at the other end. The pressing part of the switch member 33 consists of a spring 34 that always urges the switch member 33 downward (in the direction in which the pressing part 33b contacts the ground) and a ratchet gear 35 (locking part) integrated with the shaft of the drive wheel 8a. 33b is configured to protrude downward from the bottom surface of each wheel 8 when it is not in contact with the ground and protrudes downward (when the rear wheel is in a floating state). At this time, the locking portion 33a engages with the ratchet gear 35 to prevent rotation of the drive shaft 35a, thereby preserving the stored power. Further, when the rear wheel 8a is in contact with the ground, the pressing portion 3
3b is pressed upward against the spring 34,
The locking portion 33a also integrally moves upward and becomes out of engagement with the terachieto gear 35, and the stored force is released.

In the above configuration, in order to connect the traveling toy bodies 2 and 3 in the separated states of FIG. 1 a and b as shown in FIG. 1 c and d, it is necessary to The magnetic body 30 may be magnetically attached to the permanent magnet 13 by inserting the second traveling toy body 3 into the permanent magnet 13. At this time, the drive wheels 8a of the second traveling toy body 3 are in a floating state so as not to be in contact with the ground, and the pressing portion 33b of the switch member 33 constituting the storage force holding and releasing mechanism 31 is Since the locking portion 33a protrudes downward and engages with the ratchet gear 35, the drive shaft of the drive wheel 8a is prevented from rotating.

When simultaneously winding up (accumulating power) the power sources (pullback type spring units) of the connected traveling toy bodies 2 and 3, first push the body 5 of the first traveling toy body 2 against the spring 26. The second traveling toy concrete 3 is supported by pressing downward.
ground the rear (drive wheel) of the At this time, the drive wheels of the traveling toy bodies 2 and 3 are in contact with the ground at the same time, so if the connected toy bodies are moved rearward (in the winding direction of the power source) as a unit, each drive wheel will rotate. The power springs of each power source are stored by this. When the force pressing the body 5 is released, the spring 26 causes the body 5 to move upwardly away from the chassis 25, so that the drive wheels 8a of the second traveling toy body 3
It also stands out. At this time, the driving force is not transmitted to the driving wheel 8a, but the driving force is transmitted to the driving wheel of the first traveling toy body 2, so that each connected traveling toy body 2, 3 is connected to the first traveling toy body 2. The traveling toy body 2 starts to travel forward by the driving force of the power source 20 of the vehicle.
At this time, the release mechanism is activated, and the cam 22 supported by the shaft 21 rotates in the direction shown by the arrow, and the locking body 1
5 in the connection release direction, and the permanent magnet 13 fixed to the overhang 12 is slid rearward. Therefore, the magnetic state between the permanent magnet 13 and the magnetic body 30 is forcibly released, the second traveling toy body 3 is separated from the first traveling toy body 2, and the drive wheel 8a is grounded. . When the drive wheel 8a touches the ground, the pressing part 33b of the switch member 33 is pushed into the vehicle chassis, so the locking part 33a is released from the locking state with the ratchet gear 35, and the driving force of the mainspring is transmitted to the drive wheel. The entire vehicle moves forward.
