Description

[Detailed description of the invention] This invention rotates the drive wheel backwards to wind up the mainspring in the mainspring power device, and uses the elastic force of the wound mainspring to rotate the drive wheel forward to travel. When the toy is rotated backwards while pressing the drive wheel against the floor etc., the moving toy is stopped to prevent it from moving on its own while winding the mainspring or when the winding of the mainspring is completed. This invention relates to a stopping device for a traveling toy that can be parked.

Conventionally, in this type of traveling toy, when the force pressing the drive wheel against the floor, etc. is relaxed during or after the winding of the mainspring, the drive wheel immediately rotates forward and releases the bullets accumulated in the mainspring. This was very inconvenient as the power was wasted and the winding operation of the mainspring had to be performed again. Moreover, if you let go of the running toy when the winding of the mainspring is completed, the running toy will start on its own, making it impossible to maintain a stationary state.

For this reason, for example, a stopper device for a drive device for a toy car was devised, as described in Japanese Utility Model Publication No. 45-9869, but this device simply opens the bonnet after accumulating and imparting spring force to the mainspring. It is designed so that the winding force of the mainspring is not released when the door is open, and if the force pressing the drive wheel against the floor etc. loosens during winding of the mainspring, the spring will immediately release the force. There is a risk that the elastic force that has been accumulated in the mainspring will be wasted, and if you rotate the drive wheel backwards with one hand to apply elastic force to the mainspring, then open the bonnet with the other hand. It was very troublesome as it had to be left in the door condition.

Therefore, the present invention was devised to solve the above-mentioned problems that existed in the past, and it is possible to reliably and easily accumulate and apply a winding force to the mainspring of a mainspring power device with one hand. The purpose of the present invention is to make it possible to easily release the winding spring force of the mainspring, and to make the running toy itself more interesting so that young children can enjoy playing with it.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The stopping device according to the present invention includes a vehicle chassis 30 for a traveling toy.
It has a forward rotation prevention plate A fixed to a drive wheel shaft 21 of a spring power device 20 fixed to the main body, and a stopper piece 2 that removably engages with a locking piece 1 of the forward rotation prevention plate A. A swinging arm B is swingably attached to a support plate 3 projecting from the vehicle chassis 30 via a support pin 4, and a swinging arm B is mounted so as to be able to swing freely between the locking piece 1 and the stopper piece 2. and a disengagement mechanism K that swings the disengagement mechanism K.

The forward rotation prevention plate A has a substantially cross-shaped side surface with substantially rectangular plate-shaped locking pieces 1 arranged in the vertical and horizontal directions, and a drive wheel shaft 21 is inserted into a hole bored in the center of the forward rotation blocking plate A. It is inserted and fixed to this drive wheel shaft 21. Note that the shape, number, arrangement position, etc. of the locking pieces 1 are not limited to the illustrated example and can be freely set as appropriate.

A swinging arm B having a protruding substantially rectangular plate-shaped stopper piece 2 that comes into contact with the locking piece 1 to prevent forward rotation of the forward rotation prevention plate A is inserted into a hole drilled at an appropriate position. It is swingably attached to a support plate 3 protruding from a vehicle chassis 30 via a support pin 4 .

The shape of the stopper piece 2 is not limited to the illustrated example and can be set as desired, and the support of the swinging arm B can be attached to the support plate 3 so that the swinging arm B can swing freely. If so, it can be set freely without being limited to the illustrated example. Furthermore, the shape of the swinging arm B itself, the attachment position of the swinging arm B to the support plate 3 (the position of the fulcrum of the swinging arm B), the protruding position of the stopper piece 2, etc. are subject to the disengagement described below. This can be freely set as appropriate depending on the configuration of the mechanism K, etc.

Next, the disengagement mechanism K, which is configured to disengage the engagement between the locking piece 1 and the stopper piece 2 by swinging the swinging arm B, moves the vehicle body of the traveling toy to the vehicle body fixed to the chassis 30. A bonnet 33 is swingably attached to the vehicle body base 31 via a base body 31, a protruding shaft 36 protruding from both rear sides of the base body 31, and a protrusion disposed behind the bonnet 33 and protruding from both rear sides of the bonnet 33. The roof body 32 is swingably attached to the vehicle body base 31 via a shaft 34, and when the roof body 32 is swung downward, the front edge portion of the roof body 32 projects from the rear edge of the bonnet 33. The bonnet 33 opens by pressing the protruding piece 38, the swinging arm B swings, the stopper piece 2 engages with the locking piece 1, and when the bonnet 33 is closed, the roof body 32 At the same time, the swinging arm B swings and the stopper piece 2 rises to lock the locking piece 1.
It is formed so that the engagement state with the holder is released. By the way, the roof body 32 is attached so that the protruding shafts 34 on both rear sides thereof are inserted into shaft holes 35 provided on both rear sides of the vehicle body base 31 so that it can swing freely relative to the vehicle body base 31. , the bonnet 33 has protruding shafts 36 on both rear sides that are connected to the vehicle body base 31.
They are inserted into shaft holes 37 provided on both sides of the front portion of the vehicle body base 31, and are attached to the vehicle body base 31 so as to be swingable in an open/close manner. Furthermore, this bonnet 33 has a protruding piece 38 extending horizontally at its rear end so that the front edge portion of the roof body 32 comes into contact with it in a resting manner. The front edge of the body 32 is configured to press the projecting piece 38 downward to open the bonnet 33. By the way, the swinging arm B has a roof body pushing piece 5 at its rear end and a bonnet pushing piece 6 extending upward at its front end. When the bonnet 33 is in the closed state, the roof body pushing piece 5 comes into contact with the back surface of the roof body 32 and pushes the roof body 32 upward, and when the bonnet 33 is in the open state, the roof body pushing piece 5 contacts the back surface of the roof body 32 and presses the drive wheel 22 when the bonnet 33 is in the open state. Even if the roof body pushing piece 5 is rotated backward and the lower part of the stopper piece 2 is pushed upward by the locking piece 1, the tip of the roof body pushing piece 5 is formed so as not to come into contact with the back surface of the roof body 32 which is swung downward.

Note that when the locking piece 1 and the stopper piece 2 are engaged, the forward rotation of the forward rotation prevention plate A is prevented, but the backward rotation of the forward rotation prevention plate A locks the stopper piece 2. The swinging arm B becomes able to swing so as to be pushed upward by the piece 1 and is not blocked.

The present invention is constructed as described above, and at the same time operates the disengagement mechanism K and rotates the drive wheel 22 backwards to cause the mainspring in the mainspring power device 20 to accumulate and apply elastic force, thereby causing an elastic force to be accumulated. When the accumulation and application of force is completed, the engagement between the locking piece 1 and the stopper piece 2 is released, and the toy that has been stopped is allowed to travel.

Therefore, in the stationary state device according to the present invention, the elastic energy accumulated and applied to the mainspring in the mainspring power device 20 by rotating the driving wheels 22 backward is
In a traveling toy that is consumed by forward rotation of a drive wheel 22, there is provided a substantially cross-shaped forward rotation prevention plate A fixed to a drive wheel shaft 21 to which the drive wheel 22 is fixed, and this forward rotation prevention plate.
