Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle mounting device for a selector switch, and in particular, an object of the present invention is to enable the handle of a selector switch to be mounted to an operating shaft at an arbitrary angle.

Hereinafter, the present invention will be described in detail with reference to an illustrative embodiment.

Reference numeral 1 denotes an operating mechanism body having a cylindrical front part and a box-shaped rear part with a through hole formed in the center.This main body 1 includes an operating shaft 2 that is fitted into the central through hole and is slidable in the circumferential direction. A switch operation mechanism such as an operation cam 30 and the like are built-in. The operation cam 30 is fitted and coupled to the rear end of the operation shaft 2, and has a wave-shaped portion 31 extending in the circumferential direction over the entire outer circumference at its front portion.
A cylindrical cam 32 is also formed at the rear thereof. In addition, the notch members 33, 33 and the corrugated portion 3
The helical springs 34, 34 pressing against the main body 1 are located at diagonally opposite corners 25, 25 in the rear box shape of the main body 1.
mounted on. Note that 35 and 35 are stoppers. In such a device, the follower 9 that comes into contact with the cylindrical cam 32 depends on the rotation angle position of the operating shaft 2.
5 is displaced, and the contact block 9 is turned on and off. Furthermore, the operating cam 30 is stably maintained in a stationary state with the notch member 33 fitted into the valley of the corrugated portion 31. In this case, a panel thickness adjusting ring 4 is screwed into the cylindrical front part of the main body 1, and a supporting frame 3 such as a panel is clamped between the adjusting ring 4 and the bezel 5.

FIG. 4 is a perspective view of the handle and operating shaft of the selector switch according to the present invention, and FIG. 5 shows the relationship between the handle mounting position and the rotation notch position. According to this invention, an annular projection 2a is formed on the outer periphery of the open end of the upper end of the operating shaft 2 of the selector switch, and eight strips 2b are formed extending toward the center at equal intervals inside the operating shaft 2, A plurality of concave grooves 61 into which the strips 2b are inserted are formed in the leg cylinder 63 of the handle 60 attached to the upper end of the operating shaft 2 along the axial direction, and an annular protrusion 2a of the operating shaft 2 is formed concentrically with the leg cylinder 63. Hook-shaped locking pieces 62, 62 that engage internally
has been formed. With this configuration, if the leg cylinder 63 and the operating shaft 2 of the handle 60 are each made of elastic resin, the handle 60 can be easily attached and detached with a small amount of force. Further, since the strip 2b fits into the groove 61, the handle 60 is prevented from rotating, and the locking piece 62 internally engages the annular protrusion 2a, so that the handle 60 and the operating shaft 2 can be locked. Also, since eight strips 2b are provided at equal intervals, the mounting angle of the handle 60 can be changed.
It is possible to install the handle 60 at 45 degrees offset, and if the handle 60 is of a three-notch configuration, for example, there is an advantage that the rotation notch position of the handle 60 can be selected from a number of positions such as A, B, and C as shown in FIG.

Conventionally, when attaching a selector switch handle, etc., it was not possible to freely select the attaching angle with respect to the operating shaft, but according to the present invention, the attaching angle of the handle can be selected with a very simple configuration. At the same time, the handle and the operating shaft can be locked, which is very effective in improving the operability of the switch after it is attached to the support frame 3.

Claims (1)

[Scope of Claims] 1 A plurality of concave grooves are formed in the leg barrel of the handle of the selector switch along the axial direction of the leg barrel, and a locking piece is formed on a concentric circle of the leg barrel, and the handle is An annular protrusion is formed on the outside of the upper end of the operating shaft to be attached, and the locking piece is removably locked therein, and on the inside of the operating shaft, strips are fitted into the grooves at equal intervals along the center direction of the operating shaft. A handle in a selector switch, characterized in that the angle at which the handle is attached to an operating shaft can be arbitrarily selected by selecting the relative positional relationship between the groove and the strip.
