DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical filter mounting device for mounting an optical filter on the front of a display device such as a monitor of a personal computer or a television.

[0003]

2. Description of the Related Art In a display device such as a monitor of a personal computer or a television, a ceiling light, a surrounding scenery, and the like are easily reflected on a display screen, and a displayed image is sometimes difficult to see. Therefore, in order to prevent such inconvenience, the display device is often used by attaching an optical filter to the front surface of the device. Then, a dedicated mounting tool is used for mounting the optical filter.

[0004] As such a fixture, Japanese Patent Application Laid-Open No.
The one described in Japanese Patent No. 109385 is known.

[0005] This conventional mounting device is shown in FIG.
As shown by ..., a plurality of such fixtures (four in this example) are fixed to the front surface of the display device 2 in advance, and the optical filter 3 is J-shaped. It is supported by holding it with its tongue. The optical filter 3 is attached by inserting it into the tongue, and is removed by extracting it. However, such a conventional fixture has problems as described below.

In other words, the above-described conventional mounting fixture needs to be positioned with extremely high precision in accordance with the size, mounting posture, mounting position, and the like of the optical filter when fixed to the front surface of the apparatus. If the fixed position is displaced, the optical filter cannot be stably mounted, and the optical filter will rattle during use, and will be difficult to remove during cleaning or the like.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems in the conventional mounting device and to provide an optical filter mounting device capable of easily and stably mounting an optical filter on a display device. It is in.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a holding portion for an optical filter, a mounting portion on a front surface of a display device, and a positioning portion for regulating a mounting position of the mounting portion. The present invention is characterized by the optical filter mounting tool described above. It is preferable that the holding portion and the positioning portion are relatively rotatably provided. Such a fixture can constitute an optical filter unit in combination with an optical filter.

[0009]

In FIG. 2, an optical filter mounting device 1 includes a holding portion 4 for an optical filter 3, a mounting portion 5 on the front surface of the display device 2, and a positioning for restricting a mounting position of the mounting portion 5. A part 6.

The holding portion 4 has a groove 7 slightly wider than the thickness of the optical filter 3, and the groove 7
Can be inserted and held.
The mounting portion 5 can be attached to the frame portion 8 on the front surface of the display device 2 with a double-sided tape 9. Furthermore, the positioning portion 6 can easily position the mounting position (sticking position) of the mounting portion 5 by hooking the positioning portion 6 on the step 10 formed by the frame portion 8 at the corner of the display device 2. I have. In addition, by hooking the positioning portion 6 on the step 10, the load of the optical filter 3 applied to the mounting fixture 1 can be received, and the force for separating the mounting surface can be reduced.

FIGS. 3 and 4 show an optical filter fixture according to another preferred embodiment of the present invention. This attachment 1 differs from that shown in FIG. 2 in that the holding part 4 and the positioning part 6 are configured to be relatively rotatable. That is, as shown in FIG. 4, the shaft 11 is provided in the holding portion 4, the bearing hole 12 is provided in the mounting portion 5, and the holding portion 4 is fixed to the positioning portion 6 by stopping from the back surface with the nut 13.
The positioning section 6 can be relatively rotated with respect to the holding section 4. With this configuration, the holding portion 4 can be rotated after the attachment portion 5 is attached to the frame portion 8, so that the attachment portion 5 can be attached without worrying about the direction of the groove 7. Become.

In the embodiment described above, the holding portion,
The mounting part and positioning part are lightweight and inexpensive polypropylene resin, polyethylene resin, nylon resin,
It is preferable to be made of a synthetic resin such as an ABS resin. In addition, it is preferable that the positioning portion is made of a transparent resin because information can be seen even when the screen is covered by the positioning portion.

In addition, the holding portion may have a wedge-like groove or a clip-like whole so that the held optical filter does not easily move.
In this case, even an optical filter having a slightly different thickness can be easily attached.

Further, the double-sided tape used for attaching the mounting portion may have a certain thickness and elasticity because the mounting surface may be subjected to groove processing, grain processing, or the like depending on the display device. It is preferred to use one. However, the use of a double-sided tape is not indispensable, and other sticking means such as an adhesive can be used.

FIG. 5 shows a state in which an optical filter is mounted on the front surface of a display device using the optical filter mounting device of the present invention. In this example, four attachments 1, 1,... Correspond to the four corners of the screen of the display device 2, and these four attachments 1, 1,.
The optical filter 3 is supported by. At the time of attachment, the fixtures 1, 1,... Are positioned at the corners of the screen of the display device, and after attaching with double-sided tape, an optical filter slightly larger than the display screen of the display device 2 is attached to the fixture. Insert it into the holder. However, the optical filter does not need to be installed in all four corners. For example,
It is also possible to have two locations at the top and bottom. In addition, if an elastic optical filter is used, the optical filter can be attached in accordance with the curvature of the front surface of the display device. The elastic (flexible) optical filter is made of a transparent synthetic resin substrate such as polycarbonate resin, acrylic resin, polyester resin, and styrene resin, and the thickness of the substrate is reduced to about 0.2 mm to 1.5 mm. It is obtained by doing. This optical filter also has the advantage of being lightweight.

[0016]

Since the optical filter fixture according to the present invention has the positioning portion for regulating the mounting position on the front surface of the display device, the mounting portion can be accurately positioned when mounted on the display device. Become. Therefore, the optical filter can be easily and stably attached. Further, when the holding portion and the positioning portion are configured to be relatively rotatable, the holding portion can be turned even after the attachment portion is attached,
At the time of mounting, there is no need to worry about the direction of the mounting portion.
Furthermore, if an elastic filter is used as the optical filter, it can be mounted in accordance with the curvature of the front surface of the display device.

Due to these features, the optical filter mounting device of the present invention is suitable for mounting an optical filter on a display device such as a CRT display monitor of a television or a personal computer, a liquid crystal display monitor of a desktop type, a notebook type personal computer, and a mobile gear. It can be suitably used.
