Description

[Detailed explanation of the idea] This proposal relates to a somersault device for a running toy.

There are various types of conventional running toys, such as ones that change course or reverse while running, but all of them lack interest. The purpose of this proposal is to add more interest to toy play by providing a somersault device that allows a running toy to somersault, and in particular, to make it possible to perform somersaults continuously.

The present invention will be explained below with reference to embodiments shown in the drawings.
Reference numeral 1 denotes a vehicle body of a running toy, 2 a machine frame containing a prime mover, and 3 a drive wheel shaft linked to the rotation of the prime mover, with drive wheels 4 fitted and fixed to both ends thereof. 5 is a front wheel axle, and 6 is a front wheel fitted and fixed to both ends thereof.

In the vicinity of the lower ends of both side walls of the machine frame 2, flip-up rods 9 each having a hook portion 8 formed at one end thereof are attached with pivots 9a rotatably attached near the hook portions, and near the pivot portions. One end of the tension spring 10 is fixed to the front end of the vehicle body 1, and the other end of the tension spring 10 is fixed to constantly pull the flip-up lever 9 forward. The other ends of the flip-up rods 9 are made to protrude outward through long holes 7 formed in the vehicle body 1 on both sides of the machine frame in the longitudinal direction.

11 is a stopper having engaging portions 12 that respectively engage with the hook portions 8 of the flip-up rod 9;
One end of each is rotatably attached to a shaft 11a to the machine frame 2, and the other end is a tension spring 13, each of which has one end locked to the vehicle body 1.
The other end is locked and constantly pulled downward. 14
are projecting pieces that project horizontally toward the machine frame 2 in the middle of the stoppers 11, respectively.

15 is a pinion fitted and fixed to the motor shaft. 18
is a gear fitted and fixed to a shaft 17 whose both ends protrude from both side walls of the machine frame 2, and is interlocked with the prime mover via an intermediate gear 16 and a pinion 15.

Cams 19 are fitted and fixed to both ends of the shaft 17, and the protruding portions of the cams 19 are formed so as to be able to come into contact with the protruding pieces 14 of the stopper.
In this embodiment, the cams at both ends of the shaft 17 are
It is fixed with a 90° deviation.

Next, the effect of this proposal will be explained. In FIG. 2, if one end of the flip-up lever 9 protruding outward from the vehicle body 1 is pinched and rotated to the right against the traction force of each tension spring 10, one end is pivoted 11a to the machine frame 2. The stopper 11 is pushed upward against the pulling force of the tension spring 13, and the spring-up lever 9
When the tension spring 13 reaches the state shown in FIG.
Due to the traction force, the engaging portion 12 of the stopper 11 engages with the hook portion 8 of the flip-up lever 9, and the respective devices are ready for use.

If the prime mover is started here, its rotation is linked to the drive wheels 4 via the drive wheel shaft 3, and the vehicle body starts running. On the other hand, the rotation of the prime mover drives a shaft 17 via a pinion 15, an intermediate gear 16, and a gear 18, and rotates a cam 19 fitted and fixed to both ends of the shaft 17. Since the protruding part of the cam 19 is formed so as to be able to come into contact with the protruding piece 14 of the stopper 11, at a predetermined point while the vehicle is running, the protruding part of the cam 19 pushes up the protruding piece 14 and pushes up the protruding piece 14 of the stopper 11. The engaging portion 12 disengages from the hook portion 8 of the flip-up lever 9, and the now free flip-up lever 9 instantaneously rotates to the left in FIG. 6 due to the traction force of the tension spring 10, returning to the state shown in FIG. 2. do. In this process, the part of the flip-up lever 9 that protrudes outward from the vehicle body strongly hits the floor, and as a reaction, the vehicle body flips up into the air, performs a somersault, and lands. Then, as the vehicle continues to travel, the other cam 19 similarly pushes up the other projecting piece 14 and disengages the engagement portion 12 of the stopper 11 from the hook portion 8 of the flip-up lever 9. , the car body seems to do a somersault again.

As described above, according to the present proposal, a running toy can perform a somersault, and moreover, it can perform a somersault twice while running, so it can perform a somersault once while running. This adds more interest to toy play compared to various devices of conventional traveling toys that merely change the course while running.

Furthermore, since the present invention does not limit the number of the flip-up levers 9, stoppers 11, and cams 19, the required number of cams are fitted and fixed onto the shaft 17 with respective deviations, and the corresponding flip-up levers 9 and stoppers are fitted and fixed. 11, it is possible to provide a running toy that somersaults intermittently or continuously while running, and its practical effects are great.

Claims (1)

[Scope of utility model registration request] Their base ends are rotatably attached to both sides of the machine frame, and each is pulled by a tension spring so as to be biased freely to rotate at a required angle from one side to the other. A pair of flip-up levers each having a hook portion for holding them in place, and a locking member whose base end is rotatably pivoted to the machine frame and which is pulled by a tension spring and engages with the hook portion of the flip-up lever. A projecting piece that is provided with a joint part, rotates in conjunction with the prime mover, and is contacted by a cam that is provided so that the contact position is appropriately shifted to release the engagement between the hook part of the flip-up lever and the engaging part.
