Abstract

PROBLEM TO BE SOLVED: To meet the needs for reducing man-hours for an electromagnetic wave shielding glass glazing work, because a process of inserting a conductive material between an electromagnetic wave shielding glass pane and a sash is needed more than that for a conventional plat glass glazing work which does not use the electromagnetic wave shield glass pane. SOLUTION: Part or all of the glazing channel is made of a conductor, so as to allow the conductor to make the conductor part of the electromagnetic wave shielding glass and the conductor part of the sash conductive.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic shielding glass and a glazing channel used when the electromagnetic shielding double glazing is fitted into a sash.

[0002]

2. Description of the Related Art In a construction in which an electromagnetic shielding glass is fitted into a frame, it is necessary to electrically connect a conductive material such as a metal mesh or a conductive film used for the electromagnetic shielding glass to a conductive member of a sash.

As a method of electrically conducting, a backup material containing a conductive material such as a metal material or carbon is inserted between the conductive member of the electromagnetic shielding glass or the electromagnetic shielding double glass and the conductive member of the sash. ing.
FIG. 3 is a view showing an example in which the electromagnetic shielding double glass is applied by a conventional method. A backup material 10 is inserted between the sash 8 or the pressing edge 11 and the electromagnetic shielding glass 7, and further, the backup material 10 is sealed with the sealing material. A metal mesh 9 is inserted between the material 12 and the metal mesh 9 to conduct electricity between the sash 8 or the pressing edge 11 and the electromagnetic shielding double glass.

[0004]

[0005] Compared with the conventional work of inserting a flat glass sheet without using the electromagnetic shielding glass, the work of inserting the electromagnetic shielding glass requires an additional step of inserting a conductive material between the electromagnetic shielding glass and the sash. Therefore, it has been desired to reduce this.

[0005]

A glazing channel according to the present invention is a glazing channel used for fitting an electromagnetic shielding glass into a frame, wherein a part or the whole of the glazing channel is formed of a conductive material, and the conductive material is formed of an electromagnetic material. It is characterized in that the conductor of the shielding glass and the conductive portion of the sash are conducted.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When a part of the glazing channel is formed of a conductor, for example, vinyl chloride, urethane resin, silicon resin, fluorine resin, NB
Synthetic rubber such as R, SBR, etc., and a conductive portion made in advance from a metal plate are integrally formed. The conductive part made of a metal plate is prepared before integral molding, and the resin is integrally molded through the conductive part through the mold of the extruder, or the mold is used, and the metal plate is formed in the mold. The formed conducting portion may be held, and a resin may be poured into the conducting portion to be integrally molded. Further, the resin portion may be formed by a pultrusion molding machine or an extrusion molding machine and integrated with a conductive portion made of a metal plate.

[0007] Instead of the conductive portion made of a metal plate, a conductive portion may be formed by kneading a powder of carbon, chromium, nickel, copper, or the like with a resin and giving the resin a conductivity.

[0008] The glazing channel thus formed is desirably integrated in advance with the electromagnetic multilayer glass in order to facilitate the work of inserting the electromagnetic shielding glass. Also, when integrating, apply a resin with conductivity to the inside of the groove of the glazing channel or to the conductive member near the edge of the electromagnetic shielding glass, and bond the electromagnetic shielding glass and the glazing channel Is also good. In this case, the amount of the electromagnetic shielding glass swallowed into the glazing channel can be adjusted by the resin having conductivity.

Further, when the conductive portion of the glazing channel does not come into contact with the sash, a conductive resin is applied or a metal film is applied to the outer surface of the resin portion of the glazing channel to form an electromagnetic shielding glass. And the sash.

When the entire glazing channel is formed of a conductor, a powder of carbon, chromium, nickel, copper or the like is kneaded with a resin to form the glazing channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a glazing channel integrally formed with a conductive portion made of a metal plate and a soft vinyl chloride resin or a hard vinyl chloride resin.

A metal plate a and a metal plate c are connected by a metal plate b, and a conductive portion 1 having a groove between the metal plate a and the metal plate c is manufactured. Next, the resin part of the glazing channel composed of the hard vinyl chloride resin 2 and the soft vinyl chloride resin 3 was molded by an extruder, and was fitted into a groove between the metal plates a and c to be integrated. .

Further, a conductive vinyl chloride resin 4 containing carbon was coated on the outer surface of the glazing channel.

The glazing channel 5 produced in this manner is wound around an electromagnetic shielding multi-layer glass 7 whose edge is covered with a metal tape 6, and as shown in FIG. The shielding glass 7 was integrated. The electromagnetic shielding multilayer glass 7 and the sash 8 are electrically connected by the conductive portion 1 of the glazing channel 5 and the conductive vinyl chloride resin 4 to form an electromagnetic shielding window.

FIG. 3 is a sectional view showing an example of construction of an electromagnetic shielding glass by a conventional method. The electromagnetic shielding window of this example was confirmed to have the same electromagnetic shielding performance as compared with an electromagnetic shielding window in which conduction between the electromagnetic shielding multilayer glass 7 and the sash 8 was conducted using the metal mesh 9.

[0017]

The glazing channel of the present invention has made it possible to provide an inexpensive electromagnetic shielding window.
