Description

[Detailed Description of the Invention] The present invention relates to a device with an improved mounting structure for attaching a thin plate for display or decoration to an exterior frame.

First, a conventional method of attaching a thin plate as described above will be explained with reference to FIG. In the same figure, 1
is provided on the outer frame 2 of a rice cooker, for example, and covers an indicator lamp 3 provided in the outer frame 2 or a switch (not shown), etc., such as a switch case; It is a mounting hole. Reference numeral 5 denotes a recessed portion formed in the switch case 1 at a position facing the indicator lamp 3, and this recessed portion 5 has a recessed portion so as to cover an opening 5a formed therein to allow light from the indicator lamp 3 to pass therethrough. A cap-shaped lamp cover 6 is arranged. Reference numeral 7 denotes a metal thin plate for display or decoration, and the outer peripheral edge and central part of this plate have tongue-like mounting legs 8 and through holes 9 corresponding to the mounting holes 4 and recesses 5 of the switch case 1, respectively.
is formed. When attaching such a thin plate 7 to the switch case 1, the mounting leg 8 is inserted into the mounting hole 4 in a state in which the opening peripheral edge of the through hole 9 is brought into contact with the lamp cover 6. Then, the mounting legs 8 are bent to prevent the thin plate 7 from coming off. This conventional structure has the advantage that by fixing the thin plate 7 to the switch case 1, the lamp cover 6 is automatically held, reducing the number of fixing points. However, since the mounting legs 8 partially extend from the thin plate 7, material removal is poor and this tends to be disadvantageous in terms of cost.Furthermore, if the thin plate 7 is to be attached or removed for some reason, the mounting legs 8 must be removed each time. Since the mounting legs 8 have to be bent and stretched, there is a drawback that the mounting legs 8 may be broken and cannot be reused.

The present invention was made to eliminate the above-mentioned drawbacks, and its purpose is to prevent thin plates for display or decoration from becoming unusable due to repeated attachment and detachment, and to prevent thin plates and lamps from attaching to the exterior frame. To provide a display device for equipment in which the number of places where a cover is fixed can be reduced to the same level as conventional ones.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. 11 is, for example, the outer frame of a rice cooker, 1
Reference numeral 2 denotes a vertically long exterior frame, for example, a plastic switch case, which is attached to one side of the outer frame 11, and an electric heater (not shown) for cooking rice is passed through an opening 13 formed in the front of the lower half of the frame. One end of the operating lever 14 protrudes.

Now, reference numerals 15 and 16 denote a rectangular groove and a circular mounting hole, which are formed on the front surface of the upper half of the switch case 12, respectively, and the mounting hole 16 is located approximately at the center of the area surrounded by the rectangular groove 15. ing. The outer periphery of the mounting hole 16 forms a tapered surface 17 that tapers slightly inward, and the opening periphery is cut out in a concave and convex shape along the entire circumference, and the convex protrusion is used as an elastic fin. It is set at 18. The mounting hole 16 is located close to and opposite to an indicator lamp 19 disposed within the switch case 12. Reference numeral 20 denotes a thin plate for display or decoration, which is formed into a rectangular shape by a metal plate, and further has a flange portion 20a and a through hole at the outer peripheral edge and center portion corresponding to the rectangular groove 15 and the mounting hole 16, respectively. The tapered cylindrical portion 2 acts as
1 are integrally molded. 22 is a plastic lamp cover, which has a tubular insertion portion 22.
a, a tapered step portion 22b and a rim-shaped stopper portion 22c integrally formed on the front and rear ends of the insertion portion 22a, respectively. In addition, 23 is an outer lid of the rice cooker.

To attach the thin plate 20 to the switch case 12, first, the flange portion 20a of the thin plate 20 is fitted into the rectangular groove 15. Then, the tapered cylindrical portion 21 overlaps the tapered surface portion 17, and the tapered cylindrical portion 21 and the attachment hole 16 are brought into communication. In this state, the insertion portion 22a of the lamp cover 22 is inserted into the tapered cylinder portion 21 and the attachment hole 16. Then, the stopper part 22c passes through the mounting hole 16 while expanding its diameter while causing the elastic fin 18 to bend and deform.
The stopper portion 22c is connected to the elastic fin 1 as shown in FIG.
8 and is prevented from coming off, while the stepped portion 2
2b fits into the tapered cylindrical portion 21, and the thin plate 20 fits between the stepped portion 22b of the lamp cover 22 and the switch case 12.
It is held between In this way, attachment of the thin plate 20 is completed. Further, when the thin plate 20 is to be removed for some reason, the lamp cover 22 can be pulled out by releasing the engagement with the stopper part 22c by bending the elastic fins 18.

Since the thin plate 20 is mounted in a sandwiched manner by the lamp cover 22 in this way, the switch case 12
The fixing to the lamp cover 22 is limited to the lamp cover 22, which reduces the number of fixing points, and the thin plate 20 does not become unusable even if it is repeatedly attached to and detached from the switch case 12. Moreover, since there are no mounting legs or the like that partially extend from the thin plate 20, material removal becomes easier and it is advantageous in terms of cost.

Furthermore, in this embodiment, since the tapered surface portion 17 is particularly formed, the elastic fin 18 is in an inclined state, so that when the lamp cover 22 is inserted into the mounting hole 16, the amount of deflection of the elastic fin 18 can be reduced. The operation of inserting the lamp cover 22 becomes easier. After the lamp cover 22 is inserted, the stepped portion 22b is fitted into the tapered tube portion 21, so that no gap is created between the lamp cover 22 and the tapered tube portion 21, so that the appearance is not impaired.

As explained above, the present invention can prevent thin plates for display or decoration from becoming unusable due to repeated attachment and detachment, and the attachment points of the thin plate and lamp cover to the exterior frame are the same as conventional ones. Therefore, it is possible to provide a display device for equipment that can be reduced to a certain degree.
