Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch lock device, a toy and a cotton candy making machine.

[0002]

2. Description of the Related Art Conventionally, seesaw type power switches have been widely used as power switches for toys and the like. This power switch performs a seesaw operation around a predetermined axis, and is configured to press one side of the power switch when turning on the power and press the other side of the power switch when turning off the power. There is.

[0003]

However, in the case of such a seesaw type power switch, the O operation is performed by pressing the switch.
Since the power is turned on and off, even if the power is not turned on or off, if the load acts on the power switch for some reason, it is easily turned on and off. It is left unattended, which is not preferable. In particular, it is not preferable for a toy or the like having a built-in motor or heating element. The present invention has been made in view of the above problems, and an object of the present invention is to provide a switch lock device, a toy, and a cotton candy maker that can prevent malfunction.

[0004]

A first means is a switch lock device for operation-locking a power switch that performs a seesaw operation around a first axis, and the power switch is at least when the power switch is in an OFF state. A lock member that can be engaged with the switch is provided, and the lock member is configured to move in a direction away from the power switch by manual operation to release the engagement with the power switch, When the power switch is not turned on, the urging means operates to engage the power switch so that the power switch is turned on.
It is characterized in that the power switch is automatically engaged in the FF state to lock the operation. According to this switch lock device, the power is not turned on unless the lock member is manually operated and the power switch is operated to the ON side. Therefore, the power is prevented from being accidentally turned on.

A second means is characterized in that, in the first means, the lock member is configured to lock the operation of the power switch only when the power switch is in an OFF state. According to this switch lock device, it is not necessary to manually operate the lock member to turn the power switch from the ON state to the OFF state.

A third means is the first or second means, wherein the lock member is composed of a rotating member which rotates about a second axis parallel to the first axis. Is characterized by. According to this switch lock device, when the lock member is manually operated, the lock member rotates about the second shaft against the urging force of the urging means, and the operation lock of the power switch by the lock member is released. .

The fourth means is a toy including any one of the first to third means. According to this toy, any one of the first to third means is provided, so that the power is prevented from being accidentally turned on. Further, as long as it has at least the second means, it is not necessary to manually operate the lock member when the power is cut off.

A fifth means is characterized in that, in the fourth means, the power switch and the manually operated operator are provided on different surfaces of the base body. Here, the “base” does not necessarily mean a base, but means a general object to which a power switch is attached. According to this toy, since the power switch and the operating element are located on different surfaces of the base body, it is difficult to operate them with one hand at the same time.

A sixth means is characterized in that, in the fourth means, the power switch and the manually operated operator are provided on the opposite surface of the base body. Here, the meaning of "base" is the same as in the case of the fourth means. According to this toy, since the power switch and the manipulator are on the opposite surface of the base body, it is more difficult to operate them with one hand at the same time. Therefore, the power cannot be turned on unless the power is turned on.

The seventh means is a cotton candy making machine including any one of the first to third means. According to this cotton candy making machine,
Since any one of the first to third means is provided, it is possible to prevent the power from being accidentally turned on. In the case of a cotton candy making machine, this prevention of power-on is particularly effective because it has a motor and a heating element. Further, as long as it has at least the second means, it is not necessary to manually operate the lock member when the power is cut off.

An eighth means is characterized in that, in the seventh means, the power switch and the manually operated operator are provided on different surfaces of the base body. Here, the meaning of "base" is the same as in the case of the fourth means. According to this cotton candy making machine, since the power switch and the operator are on different surfaces of the base body, it is difficult to operate them with one hand at the same time.

A ninth means is characterized in that, in the seventh means, the power switch and the manually operated operator are provided on the opposite surface of the base body. According to this cotton candy making machine, since the power switch and the operator are located on different surfaces of the base body, it becomes more difficult to operate them with one hand at the same time. Therefore, the power cannot be turned on unless the power is turned on.
