Description

[Detailed Description of the Invention] The present invention relates to a multi-switch device that allows a single knob operation to simultaneously or independently operate multiple operations in the outer peripheral direction of the knob and in the downward direction of the knob.

That is, in the present invention, a main shaft equipped with a knob at one end is slidably inserted into the upper and lower side plates of the main body, and the main shaft insertion hole in the upper side plate has a large diameter to allow the main shaft to tilt in the lateral direction. A coil spring is provided at the bottom to urge the main shaft upward and hold it in a neutral position, and a stopper for preventing the main shaft from coming off upward is provided at the lower end of the main shaft, facing the lower side plate. The machine is characterized by a multi-switch device in which a plurality of limit switches are disposed facing the outer circumferential surface of the main shaft, and limit switches are arranged facing each other at the lower end of the main shaft.

The present invention will be described below based on embodiments shown in the drawings.

In the figure, 1 and 2 are side plates that constitute the main body of the multi-switch, which are provided facing each other.
are integrated via a plurality of supports 3, 3 at a required interval. The main shaft 5 equipped with a knob 4 is inserted through the center of the side plates 1 and 2, and the main shaft insertion hole 1a of the side plate 1 is made larger in diameter than the main shaft 5, so that the main shaft of the lower side plate 2 is inserted. The main shaft 5 is allowed to tilt using the hole as a fulcrum, and a plurality of holding fittings 6, 6, . The holding fittings 6, 6 are provided at one or more locations along the outer circumferential direction of the spindle at regular intervals. Each of the holding fittings 6 is provided with a limit switch 7 such that an operating piece faces the outer circumferential surface of the main shaft on the inside. In this case, various fixing methods can be employed, such as a method of fixing one limit switch to one holding fitting, or a method of fixing one limit switch by sandwiching it between one piece of an adjacent holding fitting. A spring 8 is fixed to one end of the main shaft 5 (in the figure, the lower end side), and the other end of this spring 8 is fixed to the side plate 2, and the main shaft 5 is moved by the spring 8 by operating a knob 4 provided thereon. After swinging or sliding due to pressure in the radial and longitudinal directions, it returns to its original position, that is, the neutral position, due to the restoring properties of the spring. In this case, a stopper 9 is provided at the lower end of the main shaft and on the outside of the side plate 2 (on the bottom surface in the drawing) to prevent the main shaft 5 from slipping out of the side plate 2 due to the elastic force of the spring 8. A holding fitting 10 is bored in the lower surface of the side plate 2, and a limit switch 11 is provided in the holding fitting 10 so that its operation piece faces the lower end surface of the main shaft. Note that each limit switch is electrically wired so that it can perform its respective operation.

When operating the multi-switch configured as described above, the main shaft 5 must be tilted in either direction by placing a finger on the knob 4, or pushed down in the longitudinal direction of the main shaft, or a combination thereof may be performed. The outer circumferential surface and lower end surface of the spindle are opposed to this, and the limit switch in the inclined direction is
It turns on and performs the desired operation. When the external force is removed from the knob 4, the main shaft is automatically restored by the spring and the limit switch is turned off.

Moreover, the one shown in FIG. 2 is a different embodiment in which the main shaft 5a is partially changed, and the main shaft 5a is made into a pipe shape.
A center shaft 5b is slidably inserted into the main shaft 5a, a knob 4 is provided at the upper end of the center shaft 5b, and a lower limit switch is operated from the lower end surface of the center shaft 5b.
This allows for smoother tilting and sliding (pushing) operations of the main shaft. In this embodiment, in order to restore the center shaft 5b, the main shaft 5a is replaced with the center shaft 5.
A spring 5c may be provided between b.

In the present invention, the main shaft with a knob is supported on the main body by a conical coil spring so that it can tilt and slide freely, and the main shaft is provided with a plurality of limit switches in the radial direction of the outer circumference of the main shaft and at least one limit switch in the vertical direction. Since the main shaft is supported by a conical coil spring and can be tilted in any direction, the limit switch placed on the outer periphery of the main shaft can be operated arbitrarily with an extremely simple configuration, by pressing a single knob. One or more switches can be selected and operated reliably by lowering or tilting the switch alone or in combination, and the limit switch placed on the outer periphery of the spindle can be operated more easily than the limit switch provided opposite the lower end of the spindle. Since it is disposed above the coil spring, and the main shaft is tilted with the lower part as the fulcrum, there is no possibility that the lower limit switch will malfunction when tilted, and the switch device can be miniaturized.
