Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a power switching device for a toy capable of selectively outputting a rotational force from a toy drive source such as a motor or a mainspring in an arbitrary direction.

[Prior Art] For example, a running toy that uses a motor as a drive source runs and stops by turning a switch connected between a motor and a power source on and off, but it does not only run but also performs other operations (for example, If you configure the airplane toy to rotate the propeller as well as traveling with the wheels), when you stop the motor by turning off the power switch, all operations stop, so only specific operations are performed. It is not possible. Therefore, the number of driven parts is 2 depending on the number of motions of the toy.
In the above cases, a drive mechanism including a drive source such as a motor is provided for each driven part, and each drive mechanism is operated separately.

[Problems to be Solved by the Invention] However, in a toy having such a plurality of drive mechanisms, not only a drive source but also respective switches and transmission means are required, and the overall mechanism becomes complicated. There is a problem that the price is increased and the switches are arranged at several places, which makes it difficult to operate.

Therefore, an object of the present invention is to provide a power switching device for a toy capable of transmitting power from one drive source to a plurality of driven parts and independently and reliably switching the power transmission to the driven parts. To provide.

[Means for Solving Problems] The present invention provides an input shaft that is driven by a rotational force from a toy drive source, a plurality of output shafts that output the input rotational force in different directions, respectively. In a power switching device for a toy having a rotation transmission mechanism for transmitting rotation of a shaft to each output shaft via a clutch provided corresponding to each output shaft, a position for disengaging each clutch of the rotation transmission mechanism and the clutch. Via a plurality of switching levers that can be set and operated, a plurality of clutch release members that release the corresponding clutch by operating each switching lever, and a corresponding clutch release member by operating each switching lever. Locking member that is provided so as to operate in accordance with the clutch release member and that engages with the corresponding output shaft in association with the release of the clutch by the clutch release member to prevent the output shaft from rotating. It is characterized by having and.

[Operation] In the power switching device of the present invention, the switching lever engages and disengages the clutch corresponding to the output shaft to which the rotation of the input shaft is desired to be transmitted, and engages with the corresponding clutch release member when the corresponding clutch is disengaged. It has a function of preventing rotation of the output shaft corresponding to the released clutch via the member.

Specifically, when each of the switching levers is in the position for connecting the clutch, the rotation of the input shaft is transmitted to the corresponding output shaft via the clutch. From this state, when the switching lever is set to the position where the clutch is disengaged, the corresponding clutch is released by the corresponding clutch release member, and the locking member that operates in conjunction with the clutch release member causes the output shaft to move. Engage with.

Therefore, not only the rotation of the input shaft is not transmitted to the output shaft with the clutch disengaged, but also the rotation is blocked by the locking member. This prevents the output shaft that you want to stop rotating from rotating by inertia regardless of lever operation.
Switching of power transmission can be reliably achieved.
