Abstract

PROBLEM TO BE SOLVED: To reverse rotation of a motor by arranging a changeover switch on the side of a footplate (a stepping stand), and pushing this switch from the side by foot operation. SOLUTION: In this foot controller, a reverse rotation changeover switch 12 is arranged on the side of a footplate 11, and at reversely rotating time, a foot is placed on the footplate 11, and is turned leftward or rightward as a heel as the center. The side of the reverse rotation changeover switch 12 is pushed thereby, and the switch 12 is operated, and rotation of a motor is reversed. Reversing operation of the motor can be reliably, easily and quickly performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot controller, and more particularly, to a foot controller for controlling rotation of a motor or the like by foot operation, comprising a changeover switch on a side of the foot controller. By pressing the changeover switch in the lateral direction with the foot to be operated, the rotation direction of the motor can be reversed.

[0002]

2. Description of the Related Art FIGS. 2A and 2B are schematic diagrams for explaining examples of a conventional foot controller. A foot controller 5 shown in FIG. Table) 1 and a changeover switch 2, and by placing a foot on the foot plate 1 and stepping on it,
The number of rotations of a motor (not shown) is controlled in accordance with the amount of depression, and the rotation of the motor is reversed by pressing the switch 2 with a foot. The foot controller 6 shown in FIG. 2B has two foot plates (stepping steps) 3 and 4 of the same size in parallel, and controls the rotation speed of the motor with one of the foot plates. The rotation direction is reversed by the other foot plate.

[0003] In the field of dental treatment, the above-mentioned foot controller is used for controlling the rotation of a micromotor, an air turbine, and the like in a tooth cutting handpiece and the like.

[0004]

However, as a part of surgical treatment, when drilling a hole in the jawbone, for example, the hole is drilled so that the moment the jawbone is pulled out, it cannot be pulled further. It is necessary to reverse the drill, but in the conventional foot controller as described above, the foot must be once removed from the foot plate and the other foot plate must be pressed, and the switching operation is complicated. There were problems such as taking time.

The present invention has been made in view of the above circumstances, and particularly, a switch is provided on the side of a foot plate (stepping board), and this switch is pressed from the side by foot operation. Therefore, the rotation of the motor is reversed so that the reverse operation of the motor can be performed easily and quickly.

[0006]

SUMMARY OF THE INVENTION The present invention has a foot plate and a switch mechanism disposed on a side of the foot plate. By controlling the number of rotations, by switching the rotation direction of the driven device by laterally pushing the switch mechanism by foot operation, reverse operation of a motor or the like by foot operation is simple, quick, and , Which can be performed accurately.

1A to 1C are schematic views for explaining an example of a foot controller according to the present invention. In the drawings, reference numeral 10 denotes a foot controller, and 11 denotes a foot plate. ) And 12 are reverse rotation changeover switches. In the present invention, a reverse rotation changeover switch 12 is provided on the side of the foot plate 11 as shown in the figure. , The side of the reverse rotation changeover switch 12 is pressed and the switch 12 is operated to reverse the rotation of the motor.

[0008] The reverse rotation changeover switch 12 may be either a switch which is moved entirely when the side is pressed and a switch which is not moved and only the internal switch is actuated. Anything that works with. The switch may be provided on one or both sides of one of the foot plates.

[0009]

As is apparent from the above description, according to the present invention, a foot plate and a switch mechanism arranged on the side of the foot plate are provided, and the foot plate is depressed by foot operation. In this way, the rotation speed of the driven device is controlled, and the rotation direction of the driven device is switched by pressing the switch mechanism in a lateral direction by foot operation. The switching operation can be performed without any trouble, and the operation can be performed reliably, easily, quickly, and naturally without using nerves.
