Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a security window, and particularly to a security window using a conductive film.

In recent years, the proportion of glass windows has increased due to improvements in the living environment and the purpose of daylighting, and the number of large-area glass windows has increased due to improvements in technologies such as aluminum sash and glass plate manufacturing technology.

Although this tendency is suitable for the above-mentioned purpose, it poses a very big problem from the perspective of crime prevention.

Various attempts have been made to improve the security performance of such large-area glass windows, but so far nothing has been achieved that is satisfactory in terms of economy and durability.

The present inventors have discovered that conventional touch panels, air conditioners,
The present invention was achieved as a result of intensive research to obtain a window configuration that achieves this objective using a transparent conductive film that has been used to reduce the load on heating.

That is, the present invention has 1. Rigid transparent plate 1; a transparent conductive film bonded thereon and having at least a slit in the conductive layer
; and a metal member provided at both ends of the electrical flow path of the conductive layer, through which the film is passed through, and furthermore, has metal members protruding from the film surface on both sides of the film, and at least one of the protruding metal members is deformed. 2. A security window having a jig which ensures fixation and/or electrical continuity with the film by being tightened; 3. The security window according to item 1, wherein at least one of the protruding metal members is a crushable metal member, and 4. At least one of the protruding metal members is compressible and deformable. The security window of Paragraph 1, which is a metal member, is:

The rigid transparent plate in the present invention may be any inorganic or organic material as long as it constitutes a transparent window, but a glass plate, which is a common window material, is most suitable.

Next, the transparent conductive film 1 is made of a film-like substrate, for example, an organic polymer film such as a polyester film, with a transparent thin film (conductive layer) made of a conductive material provided on the surface, which is used to determine the flow of electricity. In the present invention, which has slits in at least the conductive layer, the transparent conductive film 1 can be bonded to the transparent plate 1 on either the conductive layer side or the film substrate side. In any case, the conductive layer on the film substrate is provided with one or more insulating slits as described above. Many materials and methods have been proposed for such conductive layers, such as metal films, metal oxide films, and (metal oxide films). ``Thin Film Handbook'' edited by the 131 Committee, December 10, 1981, for Ohmsha.
From page 494: “Nikkei Electronics J 1978
Year 10-30. Published by Nikkei McGraw-Hill, October 30, 1973; other known techniques are exemplified.

Among these, those in which a thin film of indium and/or tin oxide or silver and/or gold is provided by a physical paper deposition (PVD) method are preferred from the viewpoint of color tone and durability.

For the conductive film, metal jigs 4 are provided at both ends of the electrical flow path of the conductive layer to ensure fixation and/or electrical continuity with the film.

This jig passes through the film and has metal members on both sides of the film that protrude from the film surface, and by deforming at least one of the protruding metal members, it fixes and fixes the film to the film. /or ensures electrical continuity.

A preferred example of such a jig is one in which at least one of the protruding metal members is a bendable metal plate (e.g. Eyelet Stud No. 5 manufactured by Lion Office Equipment or Flex Pack manufactured by Nippon T&B). TM system flat conductor, etc.); Or, at least one of the protruding metal members is a metal member that can be crushed and deformed (for example, a rivet that can be crushed and deformed by a general impact used for connecting tin plates, etc.) ); Alternatively, at least one of the protruding metal members may be a metal member that can be expanded and deformed (for example, a rivet in the Blip system manufactured by Nippon Drive-It).

Using such a jig, the film is passed through the film at both ends of the flow path, and at least one of the protruding metal members is deformed, so that the jig is securely fixed to the film and is securely connected to the conductive layer of the film. Since they are in contact, electrical continuity is ensured, making them preferable as electrodes.

Since such members and jigs are manufactured from very thin metal plates, after the above-mentioned deformation, substantially no large convex portions are formed on the window surface at both ends, which is preferable in terms of appearance. Not only is it useful, but it is also extremely easy to install.

A protective layer or a protective film may be provided on the conductive layer to ensure wear resistance and environmental resistance of the conductive layer.

Examples of the protective layer include acrylic resin, urethane resin, epoxy resin, acrylate resin, etc.;
l? IJ 7-layer, 5i02, TiO2, TiN,
Examples include coating layers of non-conductive inorganic materials such as Tic.

As the protective film, a thermoplastic resin film is generally adopted, and polyester resins such as polyethylene terephthalate, polyolefin resins such as polypropylene, etc.
Examples include films of polyamide resin, polyacrylonitrile resin, and the like. These films may have their surfaces coated with the protective layer listed above.

Among these, those with low moisture permeability are preferred in order to prevent moisture from entering, and these films may also have a conventionally known heat ray reflecting function.

These may also be subjected to anti-glare treatment.

The gap between the electrodes of the security window thus formed is weak enough to detect if at least a portion of the transparent plate is damaged and a break occurs in the conductive layer of the transparent conductive film bonded thereto. Current is flowing. Since this current is used for the purpose of detecting breakage, there is no need to actively raise the temperature of the transparent body itself, and therefore, it may be a very weak value, for example, 100 iA or less. In this electric circuit,
A detector is connected to detect a change in resistance or a change in current caused by the rupture.

It is preferable that the security window of the present invention is protected by providing a sealing material on the end face in order to prevent disturbance of the electrical circuit due to infiltration of water removed during cleaning or the like.

The security window of the present invention is, in principle, a transparent window.

Here, transparent includes not only a state with extremely good transparency, but also a state with reduced transparency, and even a state where there is no transparency but allows light to be let in. These may be colorless or even colored.
