Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a running toy, and in particular, a remote control system that can be used to remotely transfer a running toy to a robot or from a robot to a running toy! ! This invention relates to a traveling toy that automatically changes shape depending on its length.

The purpose is to construct a running toy that can be automatically turned into an upright position with the front part as the head by remote control.
Our goal is to provide you with the best possible results.

In order to achieve the above object, the present invention has a rear wheel drive axle connected to a motor mounted on a vehicle chassis, and a chassis upright body is arranged on the rear wheel drive axle so as to be able to swing freely around the rear wheel drive axle. A swinging tooth is formed on the chassis upright, and a small gear meshing with the swinging tooth is connected to the rear drive axle via a torque limiter, and the swinging tooth is formed on the chassis upright. It is characterized in that the upright arm is formed with a length that allows it to swing from a parallel state to an upright state with the small gear.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a generally rectangular box-shaped chassis, to which a front wheel axle 2 is fixed and a rear drive axle 3 is mounted. A motor 4 is disposed approximately in the center of the vehicle chassis 1. This motor 4 is mounted on the chassis 1 so that its drive shaft 5 is perpendicular to each axle 2.3 and the drive gear 6 at the end of the drive shaft 5 is located beside the rear drive axle 3, that is, at the rear of the chassis 1.
It was placed in

The rear space of the chassis 1 from which the drive gear 6 of the motor 4 protrudes is used as a gear box 7. A transmission shaft 11 having a driven gear 8 formed of a spur gear that meshes with the drive gear 6 and a worm 10 that meshes with a worm wheel 9 of the rear drive axle 3 is fixed to the gear box 7 .

In addition to the worm wheel 9, an intermediate gear 12 is fixedly fixed to the rear drive axle 3, and a transmission gear 13 is rotatably disposed in parallel with the intermediate gear 12. Further, at both ends of the rear drive axle 3 protruding from the chassis 1, a shaft support 25 of the chassis upright 14 is rotatably disposed. The ring 16 is fixed.

The fixation of the A-m wheel 9 to the rear drive axle 3 is as follows:
This is done via the overload protection means 17. Overload protection means 17
A worm wheel locking body 19 made of a cylindrical body with a large number of locking protrusions 1B having a triangular cross section projecting from the side end face is fixed to the rear wheel drive axle 3, and this A-worm wheel locking body 19 is locked. An A-m wheel body 21 having a locking protrusion 20 on the side end surface that matches the protrusion 18 is disposed on the rear wheel drive axle 3 so as to be rotatable and movable in the axial direction. A coil spring 23 is provided, one end of which is locked by a spring locking body 22 fixed to the worm wheel body 21, and the other end of this coil spring 23 is locked to the worm wheel main body 21. 20 is always elastically pressed against the locking protrusion 18 of the worm wheel locking body 19. That is,
The worm wheel 9 incorporates an overload protection means 17, and this overload protection means 17 is composed of the worm wheel locking body 19, the worm wheel body 21, the spring locking body 22, and the coil spring 23. It is.

Therefore, even though the motor 4 is rotating, if the movement of the rear wheel 3 or the chassis upright 14 (described later) is restrained by hand, or if the movement is restricted by an obstacle or the like while the vehicle is running. In some cases, the worm wheel main body 21 moves in the axial direction against the elastic force of the coil spring 23 to escape from the locking protrusion 20 of the A-arm wheel locking body 19, so that the worm wheel main body 21 is attached to the rear wheel. This prevents each gear from idling on the drive axle 3 and being damaged due to overload.

The chassis erecting body 14 is constructed by having a pair of erecting arms 24 swingably disposed on the rear drive axle 3 via a shaft support 25, and connecting the erecting arms 24 to each other via a connecting rod 26. Yes, the periphery of the shaft support 250 protrudes from both sides and is attached to the fender.
27, making it even more perfect as a running toy.

Then, an arc-shaped notch 28 centered on the shaft support hole of the rear wheel drive axle 3 is formed in one shaft support 25, and this notch 28
A swing tooth portion 29 is formed on the periphery. In the embodiment, a swing tooth portion 2 as a part of an internal gear is provided on the outer periphery of the notch 28.
9 is formed, but the present invention is not limited to this. For example, although not shown in the drawings, a swinging tooth portion 29 may be provided as a part of a gear on the inner periphery of the notch 28, or a shaft support body 15 may be provided with a swing tooth portion 29 not shown in the drawings. A fixed rocking gear may also be used.

A pinion 30 is meshed with the swing tooth portion 29, and the pinion 30 is fixed to a transmission shaft 31 mounted on the gear box 7 so as to be parallel to the rear drive axle 3. The transmission shaft 31 is connected to the transmission shaft 31 via a torque limiter 32.
A transmission reduction gear 33 fixed to is provided. The driving wheel 33A, which is a large-diameter gear of the transmission reduction gear 33, is meshed with the intermediate gear 12 of the rear drive axle 3.

The torque limiter 32 has a fixed ring 34 and a spring locking body 35 fixed to the transmission shaft 31 at a certain distance from the fixed ring 34, and between the fixed ring 34 and the spring locking body 35, The transmission reduction gear 33 is in contact with the fixed ring 34.
is arranged rotatably, and a coil spring 36 is telescopically fitted onto the transmission shaft 31 between the transmission reduction gear 33 and the spring locking body 35. Therefore, the elastic force of the coil spring 36 presses the transmission reduction gear 33 against the fixed ring 34 to bring their side end surfaces into contact with each other, and the friction force generated on these side surfaces connects the transmission reduction gear 33 and the transmission shaft 31. It is something. When the pinion 30 is located at the end of the swinging tooth part 29 and the pinion 30 is unable to rotate any further, or when the bent part 42A of the connecting rod 42 of the bumper center part 41, which will be described later, When the transmission reduction gear 33 contacts and locks the front plate 1A, the torque limiter 32 acts and the transmission reduction gear 33 idles on the transmission shaft 31.

In addition, the driven wheel 33B of the transmission reduction gear 33 is provided with the toy main body A.
When the toy main body A rotates when the vehicle stands up, it engages with the turning gear 37 so that the toy main body A intermittently turns around one side of the rear end of the chassis 1. A turning wheel 38 at the time of standing is installed in parallel with this turning gear 37 at the time of standing. The turning wheel 38 when standing up has an elliptical or oblong shape, and the protruding portion 39 of the turning wheel 38 when rotating.
protrudes intermittently from the rear end notch 1A of the toy main body, thereby intermittently turning around one side of the rear end of the toy main body A when standing up.

An engagement pin 40 is protruded from the inside of the shaft support body 25 on the opposite side to the shaft support body on which the swing tooth portion 29 is formed. A central part 41 of the bumper which can be freely protruded and retracted in the front and rear direction is engaged through a connecting rod 42. An engagement groove 42 that engages with the engagement pin 40 is formed in the connecting rod 42 . Therefore, when the chassis upright 14 swings, the bumper central portion 41 protrudes forward from the chassis 1 due to this swing.

Various parts 46 are formed protruding from the bottom surface of the toy main body A so that the toy main body A assumes the shape of a robot when standing up, and the bottom surface of the central portion 41 of the bumper has a decoration that becomes the head of the robot. 46 is formed to protrude. Then, the central part 41 of the bumper protrudes at the same time as it stands up to the toy body,
A robot head will appear. Also, 47 in the figure
is a spoiler, and this spoiler 47 is attached to the toy body A.
This prevents the toy main body A from falling backward when the toy main body A is stood up, and also stably maintains the upright state of the toy main body A.

Next, the operation will be explained. Normally, the drive of the motor 4 is transmitted to the rear wheel drive axle 3 via the drive gear 6, the driven gear 8, the worm 10, and the worm wheel 9 (to drive forward). The transmission gear 33 that meshes with the intermediate gear 12 also rotates, but since the small gear 3°, which is coaxially fixed, is located at the end of the swing tooth section 29 when it is running, it is locked and cannot rotate. Therefore, the transmission reduction gear 33 simply idles on the transmission shaft 31 via the torque limiter 32.

Then, when the motor 4 is reversed, the rear wheel drive axle 3 is reversed, and at the same time, the transmission shaft 31 is also reversed through the intermediate gear 12, and the pinion 3o of the transmission shaft 31 rotates the shaft support 25 through the swing tooth portion 29. The upright arm 24 is swung and rotates around the rear drive axle 3. This rotation of the upright arm 24 causes the toy main body A to be in an upright state with its rear end touching the ground, and the rear wheels 16 are separated from the floor surface due to this upright state, so that the toy main body A comes to a stopped state. Further, an intermediate gear 12 of the rear drive axle 3,
Transmission reduction gear 33, transmission gear 13, standing rotation gear 37
, the turning wheel 38 rotates when standing up, and therefore turns the toy main body A in the upright state about one side of its dominant end.

Furthermore, when standing up, the bumper central portion 41 is connected via the connecting rod 42.
protrudes, and the shape of the toy body A when standing up can be made even closer to that of a robot. Incidentally, an arm 45 of this robot is attached to the front wheel axle 2 between the front wheel 44 and the chassis 1 so that it can rotate with some resistance when the robot stands up and transforms into a robot. Further, the front wheel axle 2 is non-rotatably disposed on the chassis 1. The spinner arm 45 engages with the chassis erecting body 14, and when standing up, it is separated from the notch 25A of the shaft support 25 and is pushed by the edge of the notch 25A to swing upward. When the shape changes, it is assumed that it is pushed by the upright arm 24 and returns to its original position on the side of the chassis 1.

Although not shown in the drawings, turning wheels 38 are provided not only on one side of the rear end of the toy main body A but also on the other side, and the protruding positions of the protruding parts 39 of these turning wheels 38 are set relative to each other, for example, by 90°. By shifting the robot by degrees, it will be able to walk forward when it stands up and transforms into a robot toy.

In the illustrated example, the running toy is a car, but it is of course possible to use other forms such as a tank, an airplane, a spaceship, etc.

Note that the operating method of the present invention does not matter whether it is a wired method or a wireless method.

In addition, the direction change is performed by turning the toy main body A around one side of the rear end of the toy main body when standing up, but the present invention is not limited to this. A conversion device may be attached to change direction during forward travel.

The present invention is constructed as described above, and a rear wheel drive axle 3 connected to a motor 4 is mounted on the chassis 1, and a stand erected body 14 is arranged to be swingable around the rear wheel drive axle 3. A swing tooth portion 29 is formed on this chassis upright 14, and a small gear 30 that meshes with the swing tooth portion is connected to the rear drive axle 3 via a torque limiter 32. is the undercarriage stand 14
Since the erecting arm 24 is formed to have a length that allows it to be swung by the small gear 30 from a state parallel to the bottom surface of the chassis 1 to an upright state, the chassis 1 can be erected by rotating the motor 4 in the reverse direction. Therefore, by providing a decoration 46 resembling a front image of a robot on the bottom of the chassis 1, it is possible to automatically change the form from a running toy to a robot without any manual operation by the operator. This makes it possible to provide an interesting running toy.

That is, since the chassis upright 14 is disposed on the rear drive axle 3 so as to be able to swing freely around the rear drive axle 3,
When the vehicle is rocked, the rear wheel 16 is
can be lifted from the floor. Therefore, the user does not run backwards due to the rear wheels 16 while standing, and can stably maintain the standing state. Therefore, by disposing the turning wheel 3B on the rear wheel of the toy main body A when standing up, it becomes possible to turn around the toy main body or walk when standing up.

Further, the swing tooth portion 29 of the chassis upright 14 is connected to the chassis upright 14.
Since the upright arm 24 of No. 4 is formed with a length that allows it to swing from a parallel state to an upright state with respect to the bottom surface of the chassis 1 using a small gear 30,
The chassis 1 can be automatically stopped in an upright state.

Furthermore, since the pinion 30 that meshes with the oscillating tooth 29 is connected to the rear drive axle 3 via the torque limiter 32, even if the pinion 30 is located at each end of the oscillating tooth 29, this torque can be maintained. Idle rotation by the limiter 32 can prevent damage to each component and burnout of the motor 4. Therefore, there is no need to perform cumbersome control such as stopping the motor 4 when the pinion 30 is located at the end of the swing tooth portion 29, and the configuration can be simplified.

As explained above, according to the present invention, by reversing the motor, the toy body can be automatically erected without requiring any other hand or finger operation, and the structure and control thereof are simple. This makes it possible to provide an interesting toy that can change shape by remote control, from a running toy to a robot, or from a robot to a running toy.
