Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a slide knob device used in audio equipment such as record players, electronic equipment, and the like.

BACKGROUND OF THE INVENTION In recent years, due to price competition in equipment, efforts have been made to reduce costs by simplifying mechanisms to the maximum extent possible.

An example of the conventional slide knob device described above will be described below with reference to the drawings.

FIG. 4 is an exploded perspective view of a conventional slide knob device, and FIG. 6 is a back view of the main parts thereof. In FIG. 4, 1 is a slide knob, 2 is a click spring, 3 is a ball, 4 is a rod connecting slide knob 1 and other mechanisms, and 6 is slide knob 1. Click spring 2. This is a knob holding plate that holds the ball 3.

The operation of the slide knob device configured as described above will be described below.

First, insert the slide knob 1 into the main body, and install the click spring 2 into the slide knob 1.

Next, the grooves 6a and 6c of the knob holding plate 6 having grooves for regulating the two positions of the slide knob 1, and the click spring 2
Set the ball 3 between the 1 and 3, and secure it by inserting it into the main body using the knob holding plate 6.

In FIG. 5, the ball 3 is now in the groove 6 of the knob pressing plate 6.
When the slide knob 1 is slid from the state where the ball 3 is fitted in the groove 2b, the ball 3 moves out of the groove 2b and moves to the groove 2a.

At this time, when the ball 3 escapes from the groove 5b of the knob holding plate 5, it pushes the click spring 2 incorporated into the slide knob 1, and becomes a spring with elastic force. Utilizing this elastic force, when the ball 3 falls into the other end groove 6a of the knob holding plate 6 due to the sliding of the slide knob 1, a slide knob with a click feeling is constructed.

Problems to be Solved by the Invention However, in order to make the knob click, a click spring 2 and a ball 3 are used, which requires a large number of parts, and in the above configuration, the ball must be incorporated into the spring. In addition, to adjust the feel of the knob, it is extremely difficult to adjust the thickness and material of the leaf spring, the amount of contact with the ball, etc., and there is a problem that there is variation. It had a point.

The present invention solves the above-mentioned problems.The present invention solves the above problems by bending the connecting rod and utilizing the restoring force of the click spring, ball, and resin connecting rod. It consists of a slide knob with a handle, reducing costs and improving workability. Further, the present invention provides a slide knob device in which the feel of the knob can be easily adjusted by adjusting the restoring force of the rod, that is, the bending angle of the rod.

Means for Solving the Problems In order to solve the above problems, the present invention has a groove part for receiving the rod on the fixed side (main body), and a slide knob having a support part for the rod, and a bent connection. It is configured to be attached via a rod.

Function The present invention uses the restoring force of the connecting rod by bending it to create a slide knob with a click in the above-described configuration. By doing this, we reduced the number of parts from three to one, reducing costs, and also
There is no need to assemble a ball, and the feel of the knob can be adjusted only by the bending angle of the rod, making it possible to construct a stable slide knob.

Embodiment A slide knob device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of the same device, FIG. M2 is a sectional view of a main part of the same device, and FIG. 3 is a side view of a main part of the same device.

1 is a slide knob that slides between three positions; 2 is a guide body provided on the main body 3 that guides the sliding of the slide knob 1; and a groove 2 that positions the slide knob 1 between the two positions.
It has a and 2b. 4 is a switch; 6 is a connecting rod made of a metal wire that operates the switch 4 by operating a slide knob; one end 6a contacts the switch 4, and the other end is shaped like a Z as shown in FIG. It is formed by bending.

The other end of this connecting rod 6 has an end 6b that is a knob holding plate 6.
(connection port regulated by) has an elastic force so as to press against the guide body 2 using the folded portion 6C of the mud as a fulcrum.

Further, a knob engaging portion 6d located between the end portion 6b and the bent portion 6c of the connecting rod 6 engages with a recess 1a provided in a portion of the slide knob 1.

In the above configuration, the assembly procedure is to first assemble the slide knob 2 into the main body 3, bring one end 5a of the connecting rod 6 bent into a Z-shape into contact with the switch 4, and attach the other end to the slide knob. 1 through the recess 1a, and install the end 6b of the connecting rod 6 so that it fits into the groove 2a or groove 2b of the guide body 2, press the slide knob 1 and the connecting rod 6 with the knob holding plate 6, and then remove the main body. Install it on 3.

The operation of the slide knob device configured as above will be explained.

In FIG. 3, from the state where the other end 6a of the connecting rod 6 is fitted into the groove 2a of the guide body 2, the slide knob 1 is
When the other end 6a is slid, the other end 6a rotates about the bent portion 6c so as to move away from the groove 2a and move to the groove 2b.

At this time, the elastic force of the connecting rod 6 bent into a substantially Z-shape forms a slide knob with a clicky feel.

As described above, according to the present embodiment, by utilizing the elastic force of the connecting rod 6, the recess 1a of the knob 1 is used as a force point, and the bent portion 5C of the connecting rod regulated by the knob holding plate 6 is used as a fulcrum. Then, the rod that presses against the guide body 2 moves in an arc between the grooves, and the rod with elastic force slides down the sloped surface of the groove and falls into the groove, thereby forming a slide knob with a click feeling. . Therefore, by utilizing the return force of the rod, the number of parts can be reduced, costs can be reduced, workability can be improved, and feeling can be easily adjusted, leading to improved quality.

As described above, the present invention bends the rod and utilizes its restoring force to give the rod itself a spring force, and creates a support part on the fixed side, and a support part for the knob. This is an excellent slide knob device that eliminates the click spring and pole and creates a knob with a click feeling using a single rod.It also improves workability and allows for easy adjustment of the feel. It is.
