Description

[Detailed explanation of the invention] (a) Industrial application fields Broadcasting receivers such as television receivers and radio receivers, recording and reproducing equipment such as VTRs and tape recorders, reproducing equipment such as video discs and stereos, and other operations. Any device may be used as long as it is a device that presses a knob for use.

(B) Prior Art In FIG. 1, reference numeral 2 designates operating knobs exposed from the front cabinet 3 of the television receiver 1, and a plurality of these knobs are provided for channel switching, volume power switching, hue control, and other adjustments. On the inside of the front cabinet 3 where the knob 2 is provided, the knob support 4 is attached to the front cabinet 3 as shown in FIG. The knob 2 is fixed on an operating portion 9 whose arm extends from the elongated base portion 8 of the knob support 4. A driven body 11 such as a switch mounted on a printed wiring board 10 is arranged close to the operating section 9 and is driven in response to the bending motion of the operating section. The knob support 4
As shown in FIG. 3, three operation parts 9 are provided on the left and right sides of a long base part 8, and legs 12, 12 are formed on the opposite side of the base part 8 as shown in FIG. The legs 12, 12 abut against the front cabinet 3 as shown in FIG. 2 to determine the relative position of the knob support 4 with respect to the front cabinet 3. FIG. 5 is a perspective view of the operating device seen from the inside, with the front cabinet omitted.

(C) Purpose of the Present Invention In the conventional example described above, the knob support 4 can be easily attached to the front cabinet 3 in a snap-fit manner by pushing the knob support 4 between the claw pieces 6 and 7. However, when removing the knob support 4 from the front cabinet 3, it is necessary to spread the claw pieces 6 and 7 with one hand and pull out the knob support 4 with the other hand.
It has the disadvantage that it cannot be grasped sufficiently and is difficult to remove. Even if the claw pieces 6 and 7 are expanded, the knob support 4
is slightly obstructed by the claws 6 and 7, so the knob support 4 has to be taken out with a fairly strong force, but in conventional devices, little consideration has been given to taking it out (therefore, a strong gripping force is applied). This is because they are not used to such a structure.)

In view of these points, the present invention proposes an operating device with a structure that exerts strong gripping force and pulling force.

(d) Structure of the present invention As shown in FIGS. 6 to 8, gripping ribs 30 and 31 are provided on the base portion 21.

(E) Examples of the present invention In Figures 6 to 8, in which the present invention was implemented, 1
Reference numeral 3 designates a mounting body such as the front cabinet 3 of the television receiver 1 as shown in FIG.
16, 17, and 17 are provided. Further, a pair of elongated holes 18 and 19 are formed in the mounting body 13. A first engagement in which the base portion 21, the operating portions 22 to 27 whose arms extend from the base portion 21, an extension portion 37 extending parallel to the base portion, and the claw pieces 16, 16 engage. The extension portion 37 of the integral body 20 in which the piece 28 and the second engaging piece 29 with which the claw pieces 17, 17 engage are integrally formed of a synthetic resin material.
Gripping ribs 30 and 31 are provided near the first and second engaging pieces 28 and 29 in the figure. Reference numeral 32 denotes a fitting tube formed in the base portion, and the fitting tube 32
When the integral part 20 is attached to the mounting body 13, it fits into the first boss 14 and functions for positioning.
The operating parts 22 to 27 are elastically movable up and down with respect to the base part 21 by arms 33. In the case of the embodiment, the operating parts 22 to 27 are thick, inserted into the long holes 18 and 19 of the mounting body 13, and exposed on the other side (surface) of the mounting body 13. 27 can be directly pressed by hand to drive a driven body (see 11 in FIG. 2) disposed opposite to the operating section. However, without being limited to such an embodiment, a structure may be adopted in which a knob is separately attached to or in contact with the operating section.

FIG. 9 shows another embodiment of the operating section, in which a protrusion 34 is provided in the part that comes into contact with the driven body 11 as shown in FIG. A hole 35 is provided on the opposite side so that the driving body can be driven, and into which a knob (not shown) can be positioned and fitted, as shown in FIG. In that case, the knob is attached to the operating section and the mounting body 13 in Fig. 6.
A part of the knob may be exposed to the outside through the elongated holes 18 and 19 so as to be held between the two. The first and second bosses 14 and 15 are means for fixing the printed wiring board 10 provided with the driven bodies 11 and 11 as shown in FIG.
The first and second bosses 14 and 15 are attached to the first and second bosses 14 and 15 by inserting screws (not shown) into mounting holes in the printed wiring board. The integrated object 20 is attached to or removed from the attachment body 13 by gripping the gripping ribs 30, 31 with a hand 36, as shown in FIG.

(F) Effect of the present invention In the present invention, the gripping ribs 30 and 31 are attached to the base portion 21.
Since the integrated object 20 can be removed from the mounting body 13, a strong pulling force can be applied to the integrated object, even when a blocking force is exerted by engaging means such as the claw pieces 16 and 17. , can be removed easily and reliably. This is particularly effective for devices that are placed in a relatively narrow space, such as operating devices for television receivers.

Furthermore, since the gripping rib is provided perpendicularly to an extending portion extending parallel to the base portion and at a slight distance from the operating portion, when the gripping rib is pinched with fingers, , the operation section etc. do not get in the way. Furthermore, by forming engaging pieces at both ends of the extending portion, the extending portion and the gripping rib can be reinforced, so there is no risk of damage even if the integral part is a thin-walled resin molded product. .
