Abstract

An electrical conductor element in the form of a flexible or rigid sheet is provided for detecting attempts to break into a space where valuables or money are being stored, such as a strongroom or the coin container of a slot machine. The base material of the element is in the form of a woven or non-woven material or of plastic sheeting, and the electrical conductor is in the form of wire such as enameled copper wire for electrical connection with an alarm system. The conductor is secured in place by stitching, that is to say the wire is either formed into penetrating stitches by being fed from the needle or shuttle of a sewing machine or it is fed from a stationary part of the sewing machine so as to be fixed in place by stitches or conventional textile yarn or thread. When the conductor is interrupted by drilling, sawing or the like the alarm system is activated.

Claims

1. An electrical conductor element for providing security against forceable entry into an enclosure, comprising sheeting in the form of a base and an electrical conductor arranged thereon for attachment with the circuit of a security alarm system, such wire being attached to such base by sewing, in a security alarm system connected to said electrical conductor for passing an electric current.

2. The electrical conductor element as claimed in claim 1 wherein such conductor is enameled copper wire.

3. The electrical conductor element as claimed in claim 1, wherein said conductor is attached to the base in the form of lengths which are sewn to the base by means of stitches of a thread separate from said conductor and penetrating such base.

4. The electrical conductor element as claimed in claim 1 wherein the said conductor itself is configured in the form of stitches penetrating such base.

5. The electrical conductor element as claimed in claim 1, wherein said conductor is made integrally from end to end.

6. The electrical conductor element as claimed in claim 1, wherein the base has gaps therein free of electrical conductor base.

7. The electrical conductor element as claimed in claim 1, comprising double sided adhesive film on one side of said base for attachment purposes.

8. The electrical conductor element as claimed in claim 1, wherein a rear side of the base remote from the conductor is provided with a material which has been applied in a heated to render it impermeable to water.

9. The electrical conductor element as claimed in claim 1, wherein such base is made of rigid material.

10. The electrical conductor element as claimed in claim 1, wherein said base is made of a woven material.

11. The electrical conductor element as claimed in claim 1, wherein said base is a flexible sheet of textile-like material.

12. An electrical conductor element for providing security against forceable entry into an enclosure, comprising sheeting in the form of a base and an electrical conductor arranged thereon for attachment with the circuit of a security alarm system, such wire being attached to such base by sewing, alarm means for establishing a current in said conductor and for detecting a drop in said current.
