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 improved living environments and lighting purposes, and the number of large-area glass windows has increased due to improvements in aluminum sash technology 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 economical and durable.

The inventors of the present invention have conducted extensive research to obtain a window configuration that achieves this objective using transparent conductive films that have been conventionally used in touch panels and to reduce the load on air conditioning and heating. The invention has been achieved.

That is, the present invention has the following features: 1. A rigid transparent plate 1: A transparent conductive film 2 bonded thereon and having at least a slit in the conductive layer.
; and a member having a width wider than the penetrating surface that penetrates the film and protrudes from the film surface on both sides of the film, which is provided at both ends of the electrical flow path of the conductive layer, and at least one of the protruding members By pressing one side, the film is fixed to the conductive member disposed between any of the above members and the film by causing a deformation that shortens the thickness of the penetration part of the jig in the penetration area. as well as/
Or a security window with a jig (42, 43) that ensures electrical continuity.

2. The security window of paragraph 1 above, in which the deformation of the thickness of the penetration part is achieved by misalignment of the X joint in the jig, and 3. This is the security window of item 1 above, which is caused by crushing deformation of the part.

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

Next, the transparent conductive film 2 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. At least the conductive layer includes the ribs 1 to 1. In the present invention, the transparent conductive film 2 can be bonded to the transparent plate 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 Committee, December 10, 1981, published by Ohmsha, p. 494; ``Nikkei Electronics J, 197
8th year 10-30, Nikkei McGraw-Hill Publishing, 1978 1
October 30th Daily, and 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 (42, 43) 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 penetrates the film and has a metal member wider than the penetrating surface that protrudes from the film surface on both sides of the film, and presses at least one of these protruding (metal) members. By causing a deformation that shortens the thickness of the penetration part of the jig in the penetration area, the conductive member disposed between any of the above (metallic) members and the film is fixed and/or Or ensure electrical continuity.

Preferred examples of such jigs include those illustrated in FIGS. 5a to 6a.

By using such a jig to penetrate the film at both ends of the flow path and pressing at least one protruding (metal) member, the jig is shortened in the thickness direction of the film. Since the conductive member is reliably fixed to the film and also reliably comes into contact with the conductive layer of the film, electrical continuity is ensured, making it preferable as an electrode.

When the protruding member is made of metal, the conductive member can be omitted.

Since such members and jigs are manufactured from very thin metal (or synthetic resin) plates, after the above deformation is applied, no large protrusions are formed on the window surface at both ends. Not only does it have a desirable appearance, but it is also extremely easy to install.

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

Examples of the protective layer include organic polymer layers such as acrylic resin, urethane resin, epoxy resin, and acrylate resin, 5iOz, T! Oz, TiN, TIC
Examples include coating layers of non-conductive inorganic substances such as.

As the protective film, a thermoplastic resin film is generally employed, and examples thereof include films of polyester resin such as polyethylene terephthalate, polyolefin resin such as polypropylene, 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 water permeability are preferred in the sense of preventing moisture from entering. Further, these films may have a conventionally known heat ray reflecting function. These may also be subjected to anti-glare treatment.

Between the electrodes of the security window formed in this way, there is a weak wire in order to detect if at least a portion of the transparent plate is damaged and the conductive layer of the transparent conductive film bonded to it is broken. 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 transparency itself, and therefore, an extremely weak value may be sufficient. For example, it is 100 mA or less. A detector is connected to this electric circuit for detecting a change in resistance or a change in current caused by the rupture.

The security window of the present invention is preferably protected by providing a sealant 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 in which transparency is extremely good, but also a state in which transparency is reduced, and a state in which there is no transparency but in which light can be let in. These may be colorless or even colored.
