JPS58245Y2 - Connection structure between operating member and operated member in electrical equipment - Google Patents

Description

[Detailed explanation of the invention] This invention is based on a connection structure between an operating member and an operated member in electrical equipment such as a tuner or an amplifier, and more specifically, a shaft attached to an operating member such as a knob and an operated member such as a switch or volume. This invention relates to a structure for connecting a member to an operated shaft.

BACKGROUND ART Conventionally, as a connection structure between an operating member and an operated member, a structure shown in FIG. 1, for example, is known.

That is, in FIG. 1, a shaft 2 attached to an operating knob 1 on the front panel F side and an operated shaft 4 such as a switch or volume 3 are inserted into a hollow cylindrical joint 5 from both sides, and each has a single stop. It is pressed and fixed to the inner surface of the joint 5 by screws 6 and 7.

In this connection structure, when the operated shaft 4 is fixed to the joint 5 by the set screw 7 as shown in the figure, the axes of the shaft 2 and the operated shaft 4 may not match due to misalignment or bending. However, with the structure described above, it has been impossible to adjust the two axes so that they coincide.

In such a case, when the operating knob 1 is rotated, torque unevenness will occur between the two shafts, allowing for smooth operation, but also causing force to be applied to the operated member, which may reduce the durability of the operated member. There is a problem of loss.

This invention was devised to solve the above-mentioned drawbacks, and the shaft connected to the operating member and the operated shaft of the operated member are connected via a joint.

At least one of the two shafts is fixed to the joint with a plurality of set screws so that the position thereof can be adjusted, so that misalignment of the axis between the shaft connected to the operating member and the operated shaft of the operated member can be adjusted. Further, the operated member is mounted on the chassis so as not to rotate in the direction of rotation of the operated shaft, but to be tiltable within a certain range in the longitudinal direction.

This allows the above-mentioned adjustment to be carried out smoothly.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 2, an operated member 13 such as a volume provided on the rear panel R side is operated by both an operating member on the outer surface of the front panel F, such as a knob 10, and an operating member on the outer surface of the rear panel R, such as a knob 10'. This shows an embodiment in which this invention is applied to an operating mechanism configured to be operable. The knob 10 on the front panel F side is attached to a shaft 11, and this shaft 11 The shaft 11 extends toward the volume 13 through the section B, and the extending end of the shaft 11 is fitted into one side of a hollow cylindrical joint 12 .

The shaft 11 is held down by set screws 16, 16 from both sides of the joint 120.

On the other hand, the volume 13 is configured such that its operated shaft 14 protrudes to the front side of the volume body and also to the rear side, and this volume 13 is mounted on a sub-chassis 18 near the rear panel R. Operated axis 14
The knob 10' is attached to the protruding end of the operated shaft 14 on the front side.

The protruding end on the rear side of the twisted operated shaft 14 is connected to the joint 12.
joint 1 by means of setscrews 17 and 17.
20 It is held suppressed from both sides.

By adjusting the screwing degree of the setscrews 1γ and 17, the attitude of the operated member can be changed so that the axis of the operated shaft 14 coincides with the axis of the shaft 11.

Conversely, the operated shaft 14 can be fixed with set screws 17, 17, and the shaft 11 can be adjusted using set screws 16, 16 so that its axis coincides with the axis of the operated shaft 14.

As mentioned above, the specific configuration for mounting the volume 13 so as to be able to tilt in the front and back direction is arbitrary, but for example, by loosely tightening the lock nut that fixes the volume 13 to the sub-chassis 18, Mounting play may be caused between the volume 13 and the subchassis 18, and as shown in FIG.
A notch 18a is formed at the outer edge of the mounting hole 18' of the sub-chassis 18, which is the mounting portion of the sub-chassis 18, and the volume 13 is
The volume 13 is attached to the protrusion 18b formed by the notch 18a in a fixed state in the rotational direction.
The mounting strength of the volume 13 to the sub-chassis 18 may be weakened so that the volume 13 can be tilted within a certain range in the longitudinal direction, or as shown in FIG.
The volume 13 is not directly fixed to the sub-chassis 18, but an elastic member such as a thin metal plate 19 is fixed to the sub-chassis 18, and the volume 13 is fixed to the elastic metal plate 19. It may also be configured to tilt as shown by the arrow.

In addition, the shaft 1 attached to the operating knob 10 of this invention
1 is supported by a bearing part B provided on the sub-chassis 15 and shown enlarged in FIG. The chassis 150 is abutted and fitted from both sides, and the outside of these spacers 20, 20 is connected to the shaft 11.
It has a structure in which it is slidably held by E-rings 21, 21 that are fitted to the.

As explained above, this invention connects the shaft to which the operating member is attached and the operated shaft of the operated member via a joint, and connects at least one of the two wheels to the joint with a plurality of stops so that the position can be adjusted. Since it is fixed with a screw, the axes of the operating shaft and the operated shaft can be made to coincide with each other, thereby preventing uneven torque during operation, improving operability, and improving the durability of the operated member. According to an embodiment in which the residual operated member is mounted so that it cannot rotate in the rotational direction with respect to the yarn and can tilt within a certain range in the front-rear direction, The effect of smoothly adjusting the axis of the member and the axis of the operating shaft can be obtained.
