JPS6031139Y2 - Notch lever mounting structure in operation switch - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a notch lever mounting structure in a notch mechanism for positioning the operating shaft of an operating switch at a switching position.

In the conventional notch lever mounting structure, as shown in the first example in FIG. 3, a mounting board 22 is attached to the operation shaft (not shown) side of the switch case 21, and a screw hole boss 23 is fixed to the board 22. , insert the lower end of the shaft pin 25 with both protrusions into the hole 24 of the board 22, insert the through hole 27 of the seven-piece lever 26 into the shaft pin 25, cover it with the presser plate 2B, and place the presser plate 28 on top of it. Pass the locking hole 30 so that the upper end protrusion of the shaft pin 25 fits into the hole 29, and insert the screw 31 into the screw boss 23.
The structure is fixed by screwing into the screw holes of , which increases the number of parts and makes it complicated.In addition, the width of the mounting board 22 must be made wide in order to fix the presser plate 28 with the bosses 23 at both ends. The drawback was that the installation space for the switch was limited.

Also, instead of the boss 23 with a screw hole in the first example, a holding plate mounting piece 23' is provided on the board 22' as in the second example shown in FIG. There was also a screw-fastened structure, but this also had a disadvantage in terms of space because the width of the board 22' remained the same as in the first example.

Furthermore, in the third conventional example shown in FIG. 5, a bent portion 33 for fixing the shaft pin 34 is formed on the mounting board 32, and the shaft pin is inserted through the through hole 36 of the notch lever 35 and the hole 37 of the bent portion 33. 34
The E-ring 38 is fitted into the upper and lower grooves of the coaxial pin 34 to fix the coaxial pin 34, but this method has the disadvantage that the assembly work becomes complicated.

It is an object of the present invention to provide a notch lever mounting structure that eliminates these conventional drawbacks, allows the width of the mounting board to be narrowed, and reduces the number of man-hours required.

Hereinafter, the present invention will be explained based on the embodiment shown in FIGS. 1 and 2. A locking hole 3 is bored in a mounting board 2 attached to the operating shaft 12 side of the switch case 11. In addition, insertion holes 1 for inserting the presser plate 4 from the side are provided in the upright portions on both sides.
4 is opened, and the presser plate 4 is provided with a screw hole 5.

In the figure, 6 is a notch lever, 7 is a through hole, 8 is a notch plate, 9 is a roller that engages with the recess of the notch plate, 10 is a spring that applies a clamping force between both notch levers 6 and 6, and 13 is an operating handle. .

The screw pin 1 that also serves as a support shaft for the notch lever 6 is the head 1.
The proximal end near a is a male threaded part 1b, and the intermediate part and tip part are non-threaded parts. If you insert it through and tighten it with a screwdriver etc., the male threaded part 1b at the proximal end.
is screwed into the screw hole 5 of the presser plate 4 and fixed, and the notch lever 6 is supported around the screw pin 1 so as to be openable and closable.

As described above, according to the present invention, the structure is simplified, the number of parts and the number of assembly steps are reduced, and the width of the mounting board can be narrowed, which is advantageous in terms of space.
