Description

[Detailed description of the invention] 1. Target industrial field of application This invention relates to a start control device for a traveling toy that uses a spring to travel.

Prior Art and Its Disadvantages Conventional running toys of this type have a structure in which the wheels are rotated in the opposite direction to wind up the mainspring, a so-called pullback, and then when the user releases the toy, the toy starts immediately.

Therefore, while the mainspring is wound up and the toy can be started, it is not possible to perform other operations on the traveling toy, such as loading and unloading luggage or getting on and off the doll. this is,
There was a problem with the content of learning through playing on the platform, as it was separated from the actual movement of cargo handling and people getting on and off of cars, etc., and there was no leeway in the game.

Technical Problems to be Solved In view of the above points, this invention allows the mainspring to be stopped even after being wound up, and during that time the moving toy can perform operations such as loading and unloading baggage, getting on and off the doll, etc. It is an object of the present invention to provide a start control device that allows the start of the vehicle after the end of the vehicle.

2. Means for Solving the Constituent Problem In order to achieve the above object, this invention consists of a rotation stop lever and an operating member, and the rotation stop lever is connected to one gear of the gear train of the spring-type drive unit of the traveling toy. It is set up so that it can be separated freely.
The operating member is biased to mesh with the gear, and the operating member is provided so that it can be slid into the running toy to be stored or pulled out, and when pulled out from the running toy, the rotation stop lever is engaged with the gear. to prevent the output of the mainspring drive unit, and when the tip touches the ground and can be used as a gangplank and is stored in a traveling toy, apply a force in the opposite biasing direction to the rotation stop lever to stop the rotation. The lever is held in a state separated from the gear to allow output from the mainspring drive unit.

Function After the running toy is pulled back and rotational energy is accumulated in the spring, when the operating member is moved to the first position, the lever engages with the gear of the spring drive unit, so the output of the spring is stopped. Therefore, since the wheels do not rotate, the toy will not start moving even if you take your hands off the toy.

On the other hand, when the operating member is moved to the second position, the lever is disengaged from the gear, allowing output from the mainspring and causing the wheel to rotate. Therefore, the running toy starts and runs.

Embodiment of this invention Next, an embodiment of this invention will be described based on the drawings.

A body B is fixed to the chassis A by screwing a screw 2 passing through a cylindrical portion 1 from the bottom of the chassis into a screw receiving tube (not shown) provided inside the body.

An axle 4 with wheels 3 attached thereto is supported at the rear of the upper surface of the chassis A, and a spring drive unit 5 is provided at the center of the front part of the chassis. The input and output shafts of this drive unit extend outwardly to the left and right to form an axle 6, and wheels 7 are attached to both ends of the axle.

The mainspring drive unit 5 winds up the mainspring by reversing the wheel 7 and receives input from the mainspring 8 when the wheel 7 is released, causing an output from the mainspring 8 to rotate the wheel. A gear train that inputs input and outputs from the mainspring to the axle, and one gear of the gear train when input
Horizontal hole 10 made on the side of the case by rotating _G1
It has an operating pin 11 which is moved toward one end and moved toward the other end within the horizontally elongated hole 10 by the rotation of the one gear during output.

In a preferred embodiment, the gear train is a high speed output system Gh
and a low-speed output system G1, and while the actuation pin 11 moves from one end of the horizontally long hole 10 to near the other end, the lever 13, which is swingably supported by the rack rod 12 having the actuation pin and the fulcrum 13a, is moved. Since the switching gear 14 links the high-speed output system to the low-speed output system via the switching gear 14, the output from the mainspring 8 is transmitted to the axle 6 via the low-speed output system _G1 . When reaching the other end of 10, the lever 13 causes the switching gear 14 to separate the low-speed output system G1 from the high-speed output system Gh and release the latter, so that the output from the mainspring 8 is transferred to the high-speed output system.
The configuration is such that the power is transmitted to the axle 6 via Gh.

The lever 13 is swingably supported by a fulcrum 13a, and a pin 12a provided at the other end of the rack rod 12 is movably fitted into a long hole 13c of an arm 13b extending toward the actuating pin 11 slightly above the fulcrum. The switching gear 14 is located at the upper end of the lever 13.
A shaft 14a is rotatably supported, and the shaft is slidably inserted into an arcuate groove 15 provided in the case 7.

Then, when gear G ₁ is rotated counterclockwise in FIG. 6 by the pullback and the rack rod 12 and therefore the operating pin 11 are moved to the left, the shaft of the switching gear 14 is moved by the lever 13 to one end of the groove 15. A switching gear 14 links the high-speed output system to the low-speed output system to move to the low-speed output system. On the other hand, when output is generated from the mainspring to rotate the wheel 7, the clockwise rotation of the gear _G1 causes the rack rod 12 to move to the right, and when the wheel rotates at a constant rate, that is, as shown in FIG. Then, the pin 12a hits the lever 13 and rotates it, moving the switching gear 14 to the other end of the groove 15, thereby disengaging the low-speed output system and the high-speed output system. Therefore, the wheels are subsequently rotated at high speed.

That is, until the operating pin 11 reaches the other end of the elongated hole 10, the vehicle travels at low speed, and when the operating pin reaches the other end of the elongated hole after a certain rotation, the vehicle changes to high speed travel.

One gear in the gear train of the mainspring drive unit
_G2 is exposed to the rear outside through an opening 9a provided on the back surface of the case 9.

A rotation stop lever 16 is swingably supported at an intermediate fulcrum 16a in front of the bottom of the storage space of the body B. This lever has its front end opposed to the gear _G2 of the mainspring drive unit 5, urged by a spring 17, and meshed with the gear, and the rear end of the lever 16 extending to the lower surface of the storage space. It has a taper 18 at its rear end.

At the bottom of the storage space, an operating member 19 is held by guide grooves 21 provided on both sides of the bottom of the storage space 20 so as to be able to move in and out in the front and back direction, and when pulled out rearward from the back of the body, this operating member 19 is tilted downward, and its lower end touches the ground to serve as a gangplank, and the upper surface can be used to push and roll a toy motorcycle or the like onto or from the storage space. Alternatively, the operating member may be formed in the shape of a ramp, on which the doll can be moved to get on and off.

When the operating member 19 is inserted into the storage space 20, that is, into the body B, and is pushed to a predetermined position, its front end pushes down the rear end of the rotation stop lever 16 against the spring 17, thereby pressing the lever. Shake it. As a result, the rack portion 16b provided at the front end of the lever is released from the gear _G2 , and
It has become fixed in that state.

With the above configuration, when this traveling toy is used, the wheels 3 and 7 are pressed against the traveling surface, moved back and forth several times and pulled back to wind up the mainspring, and the operating member 19 is pulled out rearward. As a result, the rack portion 16a at the front end of the rotation stop lever 16
meshes with the gear _G2 of the mainspring drive unit, so the rotation of the wheel 7 is stopped. Therefore, even if you take your hand off the running toy, it will not start.

In this way, after loading a motorcycle toy or the like on the gangplank of the operating member 19, or storing a doll or the like from the ramp into the loading space of the traveling toy, or conversely unloading it from the traveling toy, the operating member is placed inside the traveling toy again. When inserted, the lever 16 is rotated and the rack part 16a engages with the gear of the mainspring drive unit.
Since the vehicle is separated from _G2 and released from the lock, the output is allowed, the wheels 7 rotate, and the vehicle starts moving. Initially, the switching gear 14 is linked to the low-speed output system, so the traveling toy runs at low speed.

As a result, the rotation of the gear _G1 causes the rack rod 1 to
2 moves to the right, and when the wheel rotates a certain distance, that is, when traveling a certain distance, the operating pin 11 reaches the other end of the horizontally long hole 10 by the rack rod 12, and the switching gear 14 is moved into an arcuate shape by the action of the rack rod 12 and lever 13. Groove 15
Moved to the other end, converting the low speed output system G1 to the high speed output system
The wheels are rotated at high speed to separate them from Gh.
That is, a traveling toy that has been traveling at a low speed due to deceleration by the low-speed output system changes its traveling speed to a high speed while traveling.

3. Effects As described above, according to this invention, the locking piece is provided so as to be able to move toward and away from one of the gears in the gear train of the spring-type drive unit and is urged to mesh with the gear, and the locking piece is Apply force in the opposite direction to the piece,
It also includes an operating member for holding the mainspring apart from the gear, so even after winding the mainspring,
The toy can be parked, and during this time operations can be performed on the traveling toy, such as loading and unloading luggage and getting on and off the doll, and when the operation is completed, the operating member can be operated to start the toy.

Therefore, it is possible to enjoy playing around with cargo handling operations in a real car, etc., and to perform movements similar to those of getting in and out of a person using a doll, and it is also possible to expect learning effects through the simulated experience.
