Description

[Detailed description of the invention] The present invention relates to a push button tuner, in which a stopper convex portion is provided on the restraining plate, and the push button rod is assembled to the frame while rotating the restraining plate to reduce the number of parts. An object of the present invention is to provide a push button tuner that can reduce man-hours.

A conventional push button tuner is shown in FIG. In the figure, a frame 1 consists of a front side plate 1a, a rear side plate 1b (having holes 1d and 1e, respectively), and left and right side plates 1c, but only the front side plate 1a is a separate member and the others are integral. The push button rod 2 pivotally supports a regulator 5 and a restraining plate 6 on a pin 4 of a sliding plate 3, has a spring plate (not shown) interposed between both members 3 and 6, and further has a push button 7 at the left end in the figure. It is assembled so that it can slide.

Therefore, when assembling the push button rod 2 without the push button 7,
The tip fitting portion 3a of the sliding plate 3 is fitted into the hole 1e of the rear side plate 1b with the coil spring 8 interposed, and in this state, the front side plate 1a is fixed to the left and right side plates 1c. At this time, the sliding plate 3 is moved back toward the front by the coil spring 8, the front fitting portion 3b fits into the hole 1d of the front side plate 1a, and the stopper convex portion 3c comes into contact with the front side plate 1a. The rear push button 7 is commonly fitted to the front protruding portions of the sliding plate 3 and the restraining plate 6, and the assembly of the push button rod 2 is completed.

However, according to the above-mentioned conventional example, the frame 1 has a large number of parts because the frame body (rear side plate 1b and left and right side plates 1c) and front side plate 1a are separate parts, resulting in a complicated configuration and a large number of assembly steps. Also, when installing the front side plate 1a, the sliding plate 3 is held in a suspended state, but the coil spring 8
This has the disadvantage that it is difficult to hold and position it due to the applied force, and special jigs and tools are required to solve this problem.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

FIG. 2 is an assembled perspective view of a push button rod of one embodiment of the push button tuner according to the present invention, and FIGS. 3 A to 3 C are diagrams showing the procedure for assembling the push button rod to a frame, respectively. In each figure, FIG. The same parts are given the same reference numerals and their explanation will be omitted.

In FIG. 3A, the frame 11 is formed by bending (or drawing) a single metal plate to integrally form a front side plate portion 11a and a rear side plate portion 11b (having holes 11c and 11d, respectively). The push button rod 12 has the same structure as the push button rod 2 except for the sliding plate 3' and the restraining plate 6'. The sliding plate 3' is obtained by removing the stopper projection 3c from the sliding plate 3, and the restraining plate 6' is formed by integrally forming a stopper projection 6a at the lower part of the restraining plate 6.

In order to attach this push button rod 12 to the frame 11, first, without the push button 7, from the front of the frame 11, as shown in FIG.
Insert the end fitting part 3a of the sliding plate 3', the regulator 5, and the leading end of the restraining plate 6' into the hole 11c in sequence, and finally, as shown in FIG. The fitting portion 3b is fitted. At this time, the stopper convex portion 6a of the restraining plate 6' contacts and interferes with the lower edge of the hole 11c of the front plate portion 11a, so the restraining plate 6' is rotated slightly upward about the pin 4 as shown in FIG. to move the stopper convex portion 6a upward. In this state, when the sliding plate 3' is further pushed in, the tip fitting part 3a
is inserted into the hole 11d of the rear side plate portion 11b, and the stopper convex portion 6a passes through the hole 11c. When the restraining plate 6' is rotated back downward to release the pushing force, the sliding plate 3' slides back toward the front by the coil spring 8, and the stopper convex portion 6a abuts the front plate portion 11a. Next, the push button 7 is fitted and attached to the front ends of the sliding plate 3' and the restraining plate 6'.

If the regulator 5 interferes with the hole 11c of the front plate portion 11a during the insertion and insertion of the sliding plate 3', the regulator 5 may be rotated to escape in the same manner as the restraining plate 6' and allowed to pass through.

Further, when disassembling the push button rod 12, it can be easily disassembled by performing the above procedure in reverse.

As described above, according to the push button tuner of the present invention, the restraining member of the push button rod is rotatably supported on the sliding plate, and the stopper convex portion is integrally protruded from the stopper convex portion. The push button rod (without push button)
When attaching to the front and rear side plates of the frame, insert the stopper convex part of the restraining plate into the hole in the front side plate with the stopper convex part displaced by the escape rotation of the restraining plate, and then return to the normal position by rotating the restraining plate. The position of the stopper can be determined to exhibit its function. Therefore, the frame can be made into a single piece with the front and rear side plates integrally formed in advance, reducing the number of parts compared to the conventional case where only the front side plate was a separate part. This simplifies the configuration and reduces assembly man-hours, and it is not necessary to hold the push button rod in a suspended state with a coil spring during assembly, which is a major improvement in work efficiency. It is convenient because there is no need for special jigs and tools for attachment, and there is no need to remove the front side plate.
It has the advantage that the work of exchanging push button rods can be easily done and the interchangeability work efficiency can be improved.

Claims (1)

[Scope of utility model registration request] A push button rod, which includes a rotatable regulator on a sliding plate, a restraining member for restraining the same, and at least a relatively slidable push button circle, is attached to the front and rear side plate portions of the frame so as to be slidable in the front and rear directions and in the front direction. In a push-button tuner that is pressed and inserted, the restraining member is rotatably supported by the sliding plate and has a stopper protrusion integrally protruding from the front. A push button tuner is configured to come into contact with a side plate portion to determine the sliding limit of the push button rod in the return direction.
