Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a click device for confirming the rotational position of an operating shaft provided on a gas cylinder or other operated member.

(Prior Art) Conventionally, as shown in FIG. 6, a mounting board b provided on a gas tank or other operated member a is provided with a rotating plate d that rotates in conjunction with a rotating operation shaft c of the operated member a. A ball f is accommodated in the provided through hole e, and a click plate g is provided that faces the rotating plate d and comes into elastic pressure contact with the ball f, and as the operating shaft c rotates, the ball f is rotated. A device in which a ball f is recessed into a click hole h provided in the click plate g to provide a click action is known, for example, from Japanese Patent Laid-Open No. 58-5580.

(Problem to be solved by the invention) However, since the conventional click plate g is tightened and fixed on the side of the operated member a with the screw i, the processing is troublesome, such as requiring thread processing on the side of the operated member a, and the screw Since tightening work is required, the assembly process is time-consuming and the manufacturing cost is high.
Therefore, the present applicant uses screws by providing protrusions projecting outward from the rotating plate on both sides of the click hole of the click plate, and by crimping and locking each protrusion to the lower surface of the mounting board. We proposed a system in which the click plate can be attached to the mounting board without any problems.

However, when assembling such a click device on a production line, it can be assembled simply by sequentially assembling the rotating plate d and the click plate g from the axial direction onto the mounting board b provided on the operated member a. is the most desirable from an assembly point of view.

The object of the present invention is to provide a click device that can be easily assembled by simply assembling from above sequentially.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a rotating plate that rotates in conjunction with the rotating operation shaft of the operated member, and a rotating plate that rotates in conjunction with the rotating operation shaft of the operated member. A click plate made of a spring plate that elastically presses against a ball housed in a through hole provided in the plate is provided, and as the operating shaft rotates, the ball sinks into the click hole provided in the click plate. In this device, protrusions projecting outward from the rotary plate are provided on both sides of the click hole of the click plate, and a downwardly extending portion is provided at the tip of each protrusion. A bendable piece is provided, and a transparent window into which the bent piece fits is provided on the mounting board, and when the bent piece is inserted into the transparent window, the bent piece is crimped and locked to the lower surface of the mounting board. Consists of claws.

(Function) When doing this, first assemble the rotating plate by fitting it onto the operating shaft on the mounting board, insert the ball into its through hole, and then insert the bending piece from above the click plate. When the click plate provided on the mounting board is inserted into the transparent window against the spring force of the spring plate constituting the plate, the claw provided on the bent piece presses and locks the click plate on the lower surface of the mounting board, and this As a result, the click plate is held in a resiliently pressed state against the ball.

(Example) An example of implementing the present invention will be explained with reference to the attached drawings.

In the drawing, 1 is a gas stick as an operated member, 2
shows a mounting board provided on this, and on the mounting board 2 there is a rotating plate 4 that rotates in conjunction with the rotating operation shaft 3 of the operated member 1, and a transparent plate provided on the rotating plate 4. A click plate 7 is provided which elastically presses against a ball 6 housed in the hole 5, and as the operating shaft 3 rotates, the ball 6 sinks into a click hole 8 provided in the click plate 7. By doing so, you can obtain a click effect.

The configuration up to now is not particularly different from what is conventionally known.

In such a case, the present invention provides the click plate 7.
Protrusions 9 protruding outward from the rotating plate 4 are provided on both sides of the click hole 8, and a bending piece 10 that is bent downward is provided at the tip of each protrusion 9.
When the mounting board 2 is provided with a transparent window 11 into which the bent piece 10 fits, and the bent piece 10 is inserted into the transparent window 11 against the spring force of the spring plate forming the click plate 7. , a claw 1 that locks on the bottom surface of the mounting board 2
In the embodiment shown in FIGS. 1 to 3, the tip of each protrusion 9 is bent diagonally downward to form the bent piece 10, and the tip is bent approximately horizontally. The claw 12 was formed by bending.

In this case, a rotating plate 4 is mounted on the mounting board 2 so as to fit on the operating shaft 3 and rotate together with the operating shaft 3.
Assemble the click plate 7 from the top of the folded piece 1.
0 is pushed inward into the transparent window 11 and when the pressure is released, the pawl 12 is pressed against the lower surface of the mounting board 2 as shown in FIG.

4 and 5 show exploded perspective views of other embodiments, in which a bent piece 10 is provided downward at the tip of each protrusion 9, and further upwardly from the tip of the bent piece 10. A bent piece 13 facing toward is provided and both are formed into a V-shape, and a part of the bent piece 13 is cut and raised to form the claw 12. Reference numeral 14 indicates a tongue piece formed by horizontally bending the upper end of the bent piece 13 outward.

In this case, the rotating plate 4 is similar to the above-mentioned embodiment.
After assembling on the mounting board 2, the bent piece 1 configured in a V-shape is inserted into each transparent window 11 provided on the mounting board 2.
By simply press-fitting the bent pieces 10 and 13 from above, the bent pieces 10 and 13 are easily inserted into each transparent window 11, and at the same time the claws 12 are locked to the lower surface of the mounting board 2.

Note that when the tongue pieces 14, 14 are pressed inwardly, each claw 12 is released from the pressure engagement with the lower surface of the mounting board 2. Therefore, it can be easily disassembled.

(Effect of the invention) As described above, according to the invention, a bending piece that is bent downward is provided at the tip of each protrusion provided on the click plate, and the bending piece constitutes the click plate. By simply inserting the spring plate into the transparent window provided on the mounting board against the spring force of the spring plate, the claw provided on the bent piece will press and lock onto the bottom surface of the mounting board, and the click plate will be attached to the rotating plate. It is assembled in such a way that it comes into elastic pressure contact with the provided ball. That is, since the assembly can be performed entirely from one direction, it is effective in making it easier to assemble the assembly on a production line, especially for mass production.
