Description

[Detailed description of the invention] This invention is used to improve appearance by closing the gap between the inner periphery of a through-hole formed in a panel and a child to be inserted into the through-hole in various types of equipment, or to For the purpose of preventing the "burrs" etc. generated on the inner periphery of the through-hole during processing of the through-hole from coming into direct contact with the eldest child and causing damage, a cosmetic etc. It concerns the escutcheon, which is the frame and lid.

This type of escutcheon has been widely used in various devices in recent years.

By the way, when installing this kind of escutcheon, due to the accumulation of dimensional tolerances such as the positions of the through holes in the panel, the escutcheon, the heir, and the mounting of switches, volumes, and other members for attaching the heir, the heir and the escutcheon may be misaligned with each other. This often causes the eldest child to come into stronger frictional contact with the escutcheon on one side than necessary, causing the eldest child to slide or rotate with great force. .

In particular, in the case of a bush switch, for example, the structure is such that a weak spring pushes back the eldest child who is pressed with a finger, so the eldest child cannot be returned due to the frictional contact described above, and the switch is likely to malfunction. be.

Incidentally, a known device (Japanese Utility Model Publication No. 47-38852) has been proposed to solve the above-mentioned defects.

This known device has an escutcheon 1 which is annular as a whole and has a U-shaped cross section at the annular portion, as shown in FIG. This escutcheon 1 is fitted from the inside to the inner circumferential portion of the panel 3.
It is configured to be slidable in the plane direction.

Indeed, according to this known device, it is thought that the above-mentioned inconvenience caused by positional deviation can be solved.

However, the positional deviation is limited to a very small amount, and it is not possible to cope with a large positional deviation.

If this is the case, insert escutcheon 1 into panel 3 within through hole 4.
In order to be able to slide largely in the surface direction, the amount of overlap l between the circumferential groove 2 and the panel 3 must be large.

However, the annular escutcheon 1 is replaced by the through hole 4.
In a structure in which it is fitted from the inside to the inner circumferential portion of the lamp, it is practically impossible to increase the overlamp amount l.

That is, when this overlap amount l is increased,
I can no longer perform the first part of Escutcheon 1.

Therefore, the above-mentioned overlap amount l cannot be inevitably reduced, and if it becomes smaller, the sliding range of the escutcheon 1 within the through hole 4 will also inevitably become smaller, resulting in a large positional deviation as shown in -L. becomes unmanageable.

Note that if a part of the annular portion of the escutcheon 1 is cut off, it will be possible to fit the above-mentioned overlap bottle 1 even if it is enlarged to a certain extent, but it will be very unsightly and impractical. Missing.

Furthermore, it is actually not easy to fit the escutcheon 1 into the inner peripheral portion of the through hole 4 from the inside as in this known device, and the workability is poor.

The present invention was devised to correct the above-mentioned defects, and it is very easy to attach the escutcheon to the panel.Moreover, during the attachment, the escutcheon and the legitimate child would be relatively misaligned. In any case, the aim is to provide an effective escutcheon without any inconvenience.

Examples of the present invention will be described below with reference to the drawings.

First, FIGS. 2 and 3 show the first embodiment.

First, this escutcheon 11 is molded from a synthetic resin having appropriate elasticity, such as A-B-8 resin or P-P resin, and includes an annular attachment portion 12 and a ring-shaped attachment portion 12 surrounded by the attachment portion 12. The moving part 1 is arranged in the window hole 14 so that
3 and a plurality of elastic connecting portions 15 having elasticity that connect these mounting portions 12 and moving portions 13 are integrally molded with each other.

It should be noted that a heir insertion hole 10 is formed in the center of the moving part 13.

According to the escutcheon 11, the moving part 13
is supported by the mounting part 12 by a plurality of elastic coupling parts 15, so by utilizing the elasticity (bending) of these elastic coupling parts 15, this moving part 13 moves against the mounting part 12 by You can move freely to the right.

In addition, in this case, the moving range of the moving part 13 can be made larger than the white meat.

Incidentally, FIG. 4 shows the state in which the escutcheon 11 is actually attached to the panel 18.

That is, the panel 18 has a through hole 19 formed therein.

Therefore, as shown in the figure, the movable part 13 of the escutcheon 11 is made to face the through hole 19, so that the child insertion hole 10 is in communication with the through hole 19, and the mounting part 12 is attached to the through hole 19.
The mounting portion 12 is fixed to the panel 18 by adhesion using an adhesive or the like by closely contacting the rear surface 18a (or front surface) of the panel 18 at the peripheral portion thereof.

Note that the above installation is in condition, and the inner diameter/j-measure A and outer diameter dimension B of the moving part 13 of the escutcheon 11 are based on the condition that A<0<B with respect to the inner diameter dimension 0 of the through hole 19 of the panel 18. have.

That is, the moving part 13 is made large enough to cover and close the opening 1'' of the through hole 19, and the opening of the child insertion hole 10 is made smaller than the opening of the through hole 19.

As a result of the above-mentioned handling, the movable part 13 of the escutcheon 11 moves into the panel 18 within the opening of the through hole 19 of the panel 18.
Upper and lower A in Fig. 4, which is the plane direction of ? You can move freely and widely to Jl.

As long as the above-mentioned condition A<C<B is satisfied, even if the moving part 13 performs the above movement, the outer ring part of the moving part 13 will come off inside the inner circumferential surface of the through hole 19 and will not be there. There will be no unsightly gaps.

Regarding the above-mentioned adhesion, for example, as shown in the figure, it is advisable to form an annular groove 20 on the back surface 18a of the panel 18 for pouring the adhesive, and to use a method in which adhesive 21 is poured into this groove for adhesion. preferable.

Also, at this time, a protrusion or protrusion that can be fitted into the annular groove 20 is integrally formed on the mounting portion 12 of the escutcheon 11, and this is fitted into the annular groove 20. - It is also possible to strengthen the installation.

Note that the installation of the escutcheon 11 is not limited to bonding, but may also include, for example, fitting a dowel and a dowel hole,
Alternatively, various methods such as fixing with screws can be employed; however, whatever method is used, the escutcheon 11 is simply fixed to either the back surface 18a or the front surface of the panel 18 by its attachment portion 12, Compared to the method of fitting the escutcheon 11 from the inside into the inner peripheral portion of the through hole 19 of the panel 18, the installation of the escutcheon 11 is very simple.

On the other hand, reference numeral 23 denotes an internal built-in component, such as a bush switch, arranged inside the panel 18.
3 is attached to an internal built-in base, such as a substrate 24 to the printer 1, for example.

The illegitimate child 26 inserted through the illegitimate insertion hole 10 of the escutcheon 11 is attached to the illegitimate attachment shaft 25 of this switch 23.

At this time, the internal built-in parts such as the switch 23 are attached to the internal built-in base such as the printed circuit board 24 and the panel 18
Since the switch 23 and the like are incorporated inside the panel 18, the positioning of the switch 23 and the like with respect to the through hole 19 is not necessarily constant.

Further, when the escutcheon 11 is also attached by adhesive or the like, the positioning with respect to the through hole 19 is not necessarily constant.

In other words, due to the accumulation of dimensional tolerances of various parts, the axis of the heir insertion hole 10 of the escutcheon 11 and the axis of the heir attachment shaft 25 of the internally assembled parts such as the switch 23 are mutually located above and below (front and back) in the plane direction of the panel 18. This will cause the position to shift from side to side.

Therefore, if the heir 26 is inserted through the heir insertion hole 10 of the escutcheon 11 and attached to the heir attachment shaft 25 while the position has shifted, the heir 26 and the heir attachment shaft 25 will be twisted. In the escutcheon 11 of the present invention, the movable part 13 is connected to the panel 18 as described above.
Since it can freely and largely move up and down (back and forth) and left and right in the plane direction, the above-mentioned problems such as twisting do not occur at all.

That is, the amount corresponding to the above-mentioned positional deviation dimension is
Since it is absorbed by the deflection of the elastic connecting portion 15, the above-mentioned twist does not occur at all.

This prevents the eldest child 26 and the escutcheon 11 from coming into unnecessarily strong frictional contact on one side, and the eldest child 26 slides extremely lightly against the escutcheon 11 as designed.

Therefore, according to the above structure, the switch 2 by the legitimate child 26
You can always perform switch operations such as 3 etc. very easily.

Furthermore, according to the present invention, the internal built-in parts to which the heir is attached are not limited to slide type parts such as bush switches, but can be similarly applied to other rotary type parts such as rotary volume switches. I can do it.

In addition, FIG. 5 shows a second embodiment, and in this case, a so-called continuous escutcheon 28 is constructed by integrally connecting a plurality of escutcheons having the same shape or similar shape to the escutcheon 11 described above. A plurality of escutcheons 11 are integrally molded so as to be integrally connected to each other at their mounting portions 12.

Note that, in carrying out the present invention, the attachment portion 12 does not necessarily have to be annular.

Furthermore, regarding the attachment of the escutcheon 11 to the panel 18, it is not limited to the back surface 18a of the panel 18.
It is also possible to attach it to the surface side.

In summary, the escutcheon of the present invention includes a movable part having a heir insertion hole in the center thereof that communicates with the through hole formed in the panel, and a movable part that is arranged so as to surround this movable part and has the through hole in the panel. A mounting part to be attached to the peripheral part of the panel, and a plurality of elastic connecting parts that connect one of the moving parts and the mounting part to enable the moving part to move in the surface direction of the panel are integrally molded. In addition, the movable portion has a thickness that covers and closes the opening of the through hole, and the opening of the heir insertion hole of the movable portion is smaller than the opening of the through hole.

Therefore, the present invention has the following advantages.

■The movable part having the heir insertion hole is supported by the mounting part by an elastic connecting part so that it can move freely in the surface direction of the panel, and the mounting part is used to attach it to the area around the through-hole on the back side or front side of the panel. Since the escutcheon is an escutcheon, the escutcheon can be attached to the panel very simply and easily, which greatly improves work efficiency and significantly reduces costs.

■Also, since the movement range of the moving part can be freely increased without being limited to the above-mentioned installation, there is no possibility of large misalignment between this escutcheon and the child inserted into it and attached to the internal built-in parts. Even if it is raised, the sliding and rotation of the heir can be done extremely smoothly and easily.

■Furthermore, since the escutcheon has a planar shape, it is much easier to mold than conventional designs that have a U-shaped cross section, and the cost of parts can be reduced significantly. obtain.

■ Furthermore, because of the above ■, there is no need to leave a large gap between the outer periphery of the legitimate child and the inner circumference of the legitimate child insertion hole.
Therefore, it is possible to prevent dirt and the like from entering the panel through the gaps, and it also looks good.
