2. Description of the Related Art
As a blind cover that covers the opening of the housing of an electronic device such as a wireless communication device, there is a blind cover that covers the opening, but it may be lost when removed.

Further, as shown in FIG. 5, a blind cover 15 composed of a mounting portion 15a integrally formed of an elastic material such as rubber, a lid main body 15b and a thin portion 15c serving as a hinge is provided. Although there is a device that is attached to the housing 11 of the device 10 with the screw 16 and covers the opening 12 of the housing 11 with the lid main body 15b, the screw 16 cannot be installed without a tool such as a screwdriver. It took man-hours.

As a conventional blind cover having a mounting structure other than screw mounting, as shown in FIG.
A ring-shaped mounting portion 18a integrally formed of an elastic material such as rubber, a lid body 18b, and a thin-walled portion 18c serving as a hinge on a convex part 17 (for example, an antenna connector of a communication device) of the housing 11 of FIG.
The blind cover 18 consisting of and is fitted into the convex component 15 of the housing 11 at the annular mounting portion 18a, and the housing 1 is fitted at the lid body 18b.
Some of them cover the first opening 12 (for example, the option jack portion), but there is a drawback that the ring-shaped mounting portion 18a only fits into the opening 12 so that it often falls off.

Further, as shown in FIG. 7, a rectangular portion integrally formed with an elastic material such as rubber is formed on a convex portion (for example, a hand strap attachment portion of a communication device) 19 integrally formed with the housing 11 of the electronic device 10. The blind cover 20, which is formed by the rectangular mounting portion 20a, the lid main body 20b, and the thin portion 20c serving as a hinge, is fitted into the convex component 19 of the housing 11 at the square mounting portion 20a, and the opening of the housing 11 is opened by the lid main body 20b. Although there was a cover for 12, there was a drawback in that as in the case of FIG. 6, there was a lot of falling off because only the square mounting portion 20a was fitted.

Further, as shown in FIG. 8, the lid main body 21a
There is also a blind cover 21 composed of a hinge part 21b, and fitting parts 21c and 21d, in which the fitting parts 21c and 21d of the blind cover 21 are inserted into the fitting hole 11a of the housing 11. When the blind cover 21 is attached to the housing 11, the fitting portion 21d must be pulled by the tool 22 or the like,
Needed tools for installation.

Further, as shown in FIG. 9, a blind cover 23 composed of a lid body 23a, a fitting portion 23b and a hinge portion 23c.
In some cases, the fitting portion 23b is fitted into the fitting hole 11a of the housing 11 when assembling the housing components 11A and 11B, but the blind cover 23 cannot be attached after the housing 11 is assembled, and the work is not performed. I didn't like it. Furthermore, if the blind cover 23 is cut or pulled out while it is in use, the blind cover 23 cannot be attached and repaired without disassembling the housing 11.

An object of the present invention is to eliminate the above-mentioned drawbacks in mounting a conventional blindfold lid on an electronic device, to provide a blindfold lid which does not require jigs and tools in the attaching work, is easy to attach, and is not easily lost. Especially.

[0009]

A blind cover according to the present invention is a blind cover for covering an opening of an electronic device,
A lid main body made of an elastic member is provided with a tongue piece that elastically serves as a hinge.
And a second protrusion. Further, the first and second protrusions are formed in a wedge shape, a semicircular shape, a leaf spring shape, or the like.

[0010]

Operation: A lid main body made of an elastic member is provided with a tongue piece that elastically serves as a hinge, and a blind lid is formed in which wedge-shaped first and second protrusions are formed at the front and back asymmetrical positions of the tip of the tongue piece, respectively. , The tongue piece is inserted into the opening of the electronic device first, and then fitted so as to cover the opening. At this time, since the positions of the first and second protrusions are different, the resistance force at the time of insertion depends only on the deformation amount of one of the protrusions, so that insertion is easy,
The resistance force when the blindfold lid is opened depends on the deformation amount of both protrusions, so that it is difficult to shift.

1 shows a schematic view of the structure of an embodiment of a blind cover of the present invention, (A) is a schematic exploded perspective view, (B) is a side view, and (C) is a schematic perspective view after attachment. It is a figure. In FIG. 1, a blind cover 1 of the present invention comprises a lid body 2 made of an elastic material such as rubber and formed in accordance with the size of an opening 12 of a housing 11 of an electronic device 10, and an integral molding of the lid body 2. And a tongue piece 3 serving as a hinge. Asymmetrical wedge-shaped protrusions 3a with the positions of the vertices on the front and back near the tip of the tongue 3 are displaced.
And 3b are provided. Further, a plurality of engaging projections 4 are integrally formed on the side surface of the lid body 2, and the engaging projections 4 engage with the inner peripheral edge of the opening 12 when the lid body 2 is fitted into the opening 12. Then, the lid body 2 is fixed to the opening so as not to come off.

2A and 2B are views for explaining the state of the blind lid of the present invention having the above structure when it is attached to and detached from the opening of the electronic device. First, as shown in FIG. 2A, the tip of the tongue piece 3 of the blindfold lid 1 is attached to the housing 1 of the electronic device 10.
1 into the opening 12. At this time, since the front and back projections 3a and 3b of the tongue piece 3 serving as the hinge are displaced from each other at the apex positions, the tongue piece 3 is placed inside the opening 12 and the opening 12 is opened.
When inserting into the gap 13 formed by the one side edge 12a and the member 14 in the housing 11, the protrusion 3a is first deformed to form the gap 13
After passing through, the protrusion 3b is deformed and the gap 1
Pass 3

Subsequently, as shown in FIG. 2B, when the lid body 2 is fitted into the opening 12, the engaging projection 4 and the opening 12 are formed.
The lid body 2 is attached to the opening 12 by the engagement of the inner peripheral edge of the. The resistance force when the tongue piece 3 is inserted into the gap 13 is substantially the amount of deformation of either of the protrusions 3a and 3b, that is, the distance d1 or d in FIG.
Insertion is easy as it only depends on 2.

In addition, when removing the blindfold lid 1, as shown in FIG.
As shown in (D), when the lid main body 2 is lifted by hand against the engaging force of the engaging projection 4 and the inner peripheral edge of the opening 12, the lid main body 2 is disengaged from the opening 12, but the tongue piece 3 is Since the wedge-shaped projections 3a and 3b are still engaged in the gap 13, the lid body 2 is held by the housing 11. At this time,
As shown in FIG. 2 (E), the inner circumferential length e1 of the bent tongue piece 3 is
And a difference occurs in the outer peripheral length e2. However, the protrusion 3a of the tongue piece 3
Since the positions of the vertices of 3 and 3b are shifted,
When the blind cover 1 is opened, the resistance force of the tongue piece 3, which is a hinge, in the removing direction depends on two protrusions, that is, the amount of deformation of the distance d3 in FIG. 2C. Further, the protrusions 3a and 3
Since the shape of b is wedge-shaped, the blind cover 1 has an increased resistance to the direction in which it disengages from the housing 11, and is unlikely to come off.

Therefore, even if the lid body 2 is disengaged from the opening 12 by some external force, the blind lid 1 is not easily disengaged from the housing 11 but is retained because of the presence of the tongue piece 3 serving as a hinge. . As described above, the blindfold lid according to the present invention has the features that it does not require jigs and jigs in the attachment work, is easy to attach, and is hard to be removed, so that it cannot be easily lost.

Although the embodiment of the blind cover of the present invention has been described above, the present invention can be variously modified. For example, although rubber was used as the material for the blind cover in the above-mentioned embodiment, the material is not limited to rubber as long as it is an elastic member such as an elastomer. 3 and 4 show a modification of the tongue piece 3. In FIG. 3, the protrusions 3a and 3b are formed in a semicircular shape, and in FIG. 4, the protrusions 3a and 3b are formed in a leaf spring shape. The material of the tongue piece 3 can be synthetic resin or sheet metal in FIG. 3 or sheet metal in FIG. Further, as the member 14 forming the gap 13 with the inner peripheral edge of the opening 12, a part of the chassis or frame in the housing 11 may be diverted, or a dedicated member for attaching the blindfold lid is separately provided. May be.
