Description

  The present invention relates to a toy motorcycle, and more particularly to a receiving unit mounting structure in a remotely controlled toy motorcycle.

As a remotely controlled toy motorcycle, for example, there is one shown in Patent Document 1. In the toy motorcycle disclosed in Patent Document 1, a receiving unit that receives a control signal from a controller is provided so as to protrude above the loading platform (for example, Patent Document 1).
Japanese Patent Laying-Open No. 2006-81814 (see reference numeral 19 in FIG. 12)

  However, if the receiving unit is provided so as to protrude above the loading platform, there is a problem that the toy motorcycle is far from the real motorcycle and the appearance is poor. On the other hand, it is necessary to provide a receiving unit at a position where a control signal from the controller can be received at a wide angle.

  The present invention has been made in view of such problems, and an object thereof is to provide a toy motorcycle that can receive a control signal from an external controller at a wide angle and has a good appearance.

The invention of claim 1 is a toy motorcycle comprising an external controller and a toy main body that receives a control signal by infrared rays from the external controller at a receiving unit and is remotely controlled based on the control signal. The toy motorcycle is characterized in that a windshield capable of transmitting infrared rays is provided in front of a handle of the main body, and the receiving portion is provided in a portion covered with the windshield.
The invention of claim 2 is the toy motorcycle according to claim 1, characterized in that the receiving section is provided inside or inside the windshield.
Further, the invention of claim 3 is the toy motorcycle according to claim 1, characterized in that the receiving portion is provided in a portion corresponding to an instrument panel covered forward and upward by the windshield. . The “instrument panel equivalent portion” here refers to a portion in which the instrument panel is originally provided because the toy body in the toy motorcycle is often modified and the instrument panel is omitted.

  The invention of claim 4 is the toy motorcycle according to claim 1, wherein the windshield is smoked.

The invention of claim 5 is the toy motorcycle according to any one of claims 1 to 4, characterized in that the receiving portion is provided at substantially the same height as the base portion of the handle. .
A sixth aspect of the present invention is the toy motorcycle according to any one of the first to fourth aspects, wherein the receiving section is provided at a position higher than the base portion.

  The invention of claim 7 is the toy motorcycle according to any one of claims 1 to 6, wherein the toy body is of a scooter type.

According to the first to seventh aspects of the present invention, since the receiving portion is covered with the windshield, the appearance of the toy body does not deteriorate. In particular, in the case where the receiving unit is provided inside or inside the windshield, the receiving unit is difficult to visually recognize from the outside, so that the effect is high. In addition, when the receiving unit is provided in a portion corresponding to the instrument panel, the receiving unit can be regarded as an instrument, so that a sense of incongruity is reduced.
According to the first to seventh aspects of the invention, since the windshield can transmit infrared rays, the control signal can be received at a wide angle.

  According to the third aspect of the present invention, since the windshield is smoked, the receiving unit is more difficult to visually recognize from the outside.

  According to the invention of claim 5 and claim 6, it is less likely that the control signal from obliquely above is obstructed by the base portion of the handle. Since the toy body is generally run at a place lower than the external controller such as the floor surface, the effect is remarkable.

  According to the invention of claim 7, in the scooter type toy motorcycle, the cradle is provided and the occupant (doll) and the receiving unit are relatively separated from each other, so that the control signal is particularly easily received.

A toy motorcycle according to the present invention will be described below with reference to the drawings.

  The toy motorcycle is composed of a toy body 1 and a controller 2 (FIG. 6). A steering mechanism 20 (FIG. 3) and a traveling mechanism 30 (FIG. 5) are mounted on the body 10 of the toy body 1.

  The body 10 simulates a scooter, and includes a front portion 10a to which a translucent windshield 11 and a handle 12 are attached, and an intermediate portion 10b in which a cradle 13 for receiving a leg portion of an occupant doll is formed. And a rear portion 10c on which the sheet 14 is formed. The body 10 is divided into left and right parts, and a steering mechanism 20 (see FIG. 3) and a traveling mechanism 30 (see FIG. 5) are housed inside.

  As shown in FIG. 3, the steering mechanism 20 includes (1) a fork support member 21 having an operating shaft 21a attached to the rear surface, and (2) an integral locking with the body 10, and the operating shaft 21a is inserted therethrough. An operating shaft support member 22 having a hole 22a and having a protrusion 22b formed at the lower part of the rear surface; (3) a torsion coil spring 23 wound around the operating shaft 21a; and (4) a rear end of the operating shaft 21a. A sector gear 24 having a hole 24a into which the portion is tightly fitted is formed at one end, a gear 24b is formed at the peripheral edge of the rear surface, and a projection 24c is formed on the front surface, (5) a steering motor 25, and a motor shaft The pinion 26 meshes with the gear 24b of the selector gear 24. The steering mechanism 20 is housed in the front cowling 100 in front of the cradle 13.

  2 and 3, the fork support member 21 is formed with a hole 21b having an axis A inclined in the front-rear direction of the vehicle body. The fork shaft 21d of the fork 21c is centered on the axis A in the hole 21b. It is supported rotatably. A front wheel 27 is rotatably supported at the lower end of the fork 21c.

  As shown in FIGS. 2 and 3, the operating shaft 21a is installed so as to have an axis B extending horizontally in the front-rear direction of the vehicle body. The operation shaft 21 a is inserted into the hole 22 a of the operation shaft support member 22 and protrudes from the rear surface of the operation shaft support member 22. A winding portion of the torsion coil spring 23 is fitted to the protruding portion of the operating shaft 21a, and the rear end portion of the operating shaft 21a is tightly fitted to the hole 24a of the sector gear 24.

  The steering motor 25 is a DC motor that can rotate forward and backward. The steering motor 25 is installed in the lower part of the intermediate portion 10b of the body 10 so that the motor shaft extends in the vertical axis direction.

  In the steering mechanism 20 configured as described above, when the steering motor 25 is not operated, the protrusion 22b of the operating shaft support member 22 and the protrusion 24c of the sector gear 24 are twisted as shown in FIG. The sector gear 24 is held between the arm portions 23a and 23b of the coil spring 23, and the sector gear 24 is held at the neutral position. This position is the “predetermined rotational position” of the operating shaft 21a according to claim 1.

  From this state, when the pinion 26 is rotated (turned) by the steering motor 25, as shown in FIG. 4B or FIG. 4C, the sector gear according to the rotation (turning) direction of the pinion 26. 24 is rotated clockwise or counterclockwise. Then, the operating shaft 21a is rotated following the sector gear 24, and the fork support member 21 is rotated around the axis B of the operating shaft 21a according to the rotating direction. As a result, the fork 21c and thus the front wheel 27 tilt, and the front wheel 27 is steered leftward or rightward of the vehicle body according to the tilting direction.

  When the steering motor 25 is driven to rotate and the sector gear 24 deviates from the neutral position, as shown in FIG. 4B or 4C, one of the arm portions 23a and 23b of the coil spring 23 is caused by the projection 22b. Is locked, the other of the arm portions 23a and 23b is expanded against the urging force of the torsion coil spring 23 by the projection 24c. On the other hand, when the rotational drive of the steering motor 25 is released, the sector gear 24 is returned to the original state (neutral position) by the urging force of the torsion coil spring 23. Accordingly, the front wheel 27 is also in the neutral position. It is returned to (straight state).

The traveling mechanism 30 is for driving the rear wheel 31. As shown in FIG. 2, the rear wheel 31 is rotatably supported by the lower portion of the rear portion 10 c of the body 10.

It has a pair of hollow bosses 31c, 31c provided. A flywheel 32 is housed inside the wheel 31a, and a shaft 32a is provided at the center of rotation. The end portion of the shaft 32a penetrates the bosses 31c and 31c, and is further rotatably inserted into both side members 10d and 10e of the body 10.
Here, the flywheel 32 stabilizes the running posture of the toy motorcycle itself by a gyroscopic action, and is made of a metal material having a diameter and a thickness that can be accommodated in the rear wheel 31.

  The traveling mechanism 30 includes a mechanism that drives the wheel 31 a and a mechanism that drives the flywheel 32. The traveling mechanism 30 rotationally drives the rear wheel 31 at a speed suitable for traveling and rotationally drives the flywheel 32 at a speed sufficiently higher than the rotational speed of the rear wheel 31 to generate a gyro effect.

  First, a mechanism for driving the flywheel 31 a will be described. This mechanism is connected to the pinion 34 fixed to the motor shaft of the traveling motor 33 attached to the intermediate portion 10 b of the body 10 and the side member 10 e of the body 10.

In this structure, the windshield 11 is composed of two parts divided into left and right or front and rear, and the infrared sensor module 300a is installed in a hollow part formed by joining these two parts, or a recess is formed in the windshield 11. In addition, after the infrared sensor module 300a is installed in the recess, the opening of the recess is closed with a member that can transmit infrared rays.
In addition, when there exists an instrument panel equivalent part covered front and upper by the windshield 11, the infrared receiving part 1a of the infrared sensor module 300a can also be provided in the instrument panel equivalent part.
The infrared remote control receiving IC 300b includes a register that temporarily stores infrared control data detected by the detection unit, a clock generation unit that generates a control clock, and data encoded according to a certain method (encoded data). And a decoder for demodulating the signal.
The control IC 301 is mounted on a substrate 1c installed at the lower part of the middle part of the toy body 1, and includes a CPU, a ROM, and a RAM (not shown). The control IC 301 stores the control data received from the transmission unit 204 of the controller 2 in the RAM, and controls the steering motor 25 of the toy main body 1 according to the program in the ROM. The motor driving unit 302 performs forward / reverse driving of the steering motor 25 in accordance with a command from the control IC 301. A power source 1d such as a storage battery is installed below the substrate 1c.

In the toy motorcycle configured as described above, when the toy main body 1 is turned on (not shown), the traveling motor 33 is operated, and the rear wheel 31 and the flywheel 32 are rotated.
Therefore, when the toy body 1 is placed on the floor or the like, the toy body 1 goes straight.
Here, when the control button 2a of the controller 2 is operated, the steering motor 25 of the toy body 1 is driven, whereby the front wheel 27 is turned left or right. When the operation of the control button 2 a is stopped, the steering motor 25 is stopped, and accordingly, the front wheel 27 is returned to the neutral position by the urging force of the torsion coil spring 23.
