Description

[Detailed Description of the Invention] The present invention relates to a turntable, that is, a turntable on which a suitable number of people sit around a dining table, such as in a restaurant, and food is placed on the dining table.

Conventional turntables were manually operated, and when you wanted to eat something out of the dishes displayed on the rotary table, you turned the rotary table by hand.

However, this rotating operation is cumbersome as you have to push or pull the rotating plate by hand every time you want to eat, and the weight also increases as the number of dishes on the rotating plate increases. Therefore, it was difficult to rotate unless a considerable amount of force was applied.

Rotating operations were often difficult, especially when performed by children.

The present invention was developed in view of the above circumstances, and its purpose is to provide a turntable that rotates at a constant speed at all times and that can stop its rotation with a simple operation when necessary. The basic configuration to achieve the above purpose is to provide an appropriate number of casters on the back of a rotary disk centered around the support shaft, at least one of which is driven by a motor, and electrically connected to the motor. A touch plate connected to the rotary disk is installed on the surface of the rotary disk.

An example of implementing the present invention will be described below based on the drawings.

The rotary plate 1 has a scale plate 1a provided below the periphery of a circular plate having a size necessary for placing food, etc.
A support shaft 3 is attached to the center of the back surface of the disk via a support 1b, and is rotatable on the pedestal 2 or the top surface of the dining table.

Further, on the back surface of the rotary disk 1, an appropriate number of casters 4 are arranged at appropriate intervals circumferentially around the support shaft 3.
At the same time, a touch plate 5 is provided on the surface.

The caster 4 rotates the turntable 1 by rolling on the top surface of the base 2 or the dining table.
An appropriate number of motors are provided on the rear surface of the rotating platen 1, at least one of which incorporates or is connected to a motor 7 for rotating the wheels 4a. The motor 7 is driven by direct current or alternating current to rotate the wheels 4a and slowly rotate the rotating platen 1.

This rotation will always continue to rotate at a constant speed unless the electricity is turned off.

The touch plate 5 is made of a conductive metal piece, and is buried flush with the surface of the rotary disk 1 at appropriate intervals, and is electrically connected to the motor 7.

Next, to explain the operation of the electrical circuit diagram shown in Figure 4, for example, when AC is converted to DC and energized, B ₂
The relay is connected, the motor 7 rotates, and the drive of the motor 7 rotates the wheels 4a of the caster 4, thereby continuing to slowly rotate the turntable 1.

Next, if you want to stop this rotation, for example when the food you want to eat is in front of you, you can touch the touch plate 5 provided on the surface of the rotary plate 1, and the static electricity charged on your body will stop the rotation. Switch S with built-in IC circuit activates coil 6, connects _A1 relay and _A2 relay, and opens relay _B2 for a predetermined time by timer 8, stops the movement of motor 7, and stops rotation of turntable 1. stop.

When the predetermined period of time has elapsed, the timer 8 activates the _B1 relay and the coil 6 activates the _A1 relay.
The A ₂ relay is opened and the B ₂ relay is connected at the same time to drive the motor 7 and keep the turntable 1 rotating.

The invention is not limited to this circuit.

As described above, the present invention has an appropriate number of casters installed on the back of the rotary disk, at least one of which is driven by a motor, and a touch plate electrically connected to the motor is buried in the surface of the rotary disk. By supplying electricity to the motor, the rotary disk is constantly rotating, and when necessary, the rotary disk can be easily stopped by touching the touch plate, which can be provided by a simple mechanism.

Claims (1)

[Scope of utility model registration request] An appropriate number of casters are provided on the back of the rotary disk centered around the support shaft, and at least one of them is electrically connected to a drive motor to constantly rotate the rotary disk at a low speed. The turntable is provided with an appropriate number of touch plates on the surface of the rotary disk, which stop the motor for a predetermined period of time due to static electricity when touched.
