Abstract
Abstract The present invention discloses a method for interconnecting a plurality of security surfaces into a main alarm line. The method includes the steps of: placing a strip of electrically conductive foil about the periphery of each protected security surface; disposing a single-throw double-pole switch between adjacent, partially overlapping security surfaces which are movable with respect to each other; mutually connecting the peripherally disposed conductive strips of adjacent security surfaces so as to form a single circuit loop from the conductive strips placed about the periphery of adjacent security surfaces, the connection across adjacent surfaces occurring through the single-throw double-pole switch; and connecting the output of each of the single circuit loops formed through the use of the double-pole switch to the main alarm line. Further, the single-throw double-pole switch exhibits a novel structure which facilitates its usage in the present security method.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A system for interconnecting a plurality of security surfaces into a main alarm line, comprising: (a) a strip of electrically conductive foil placed about the periphery of each of a plurality of security surfaces; (b) a plurality of foil bridges, each of said bridges installed between adjacent, partially overlapping security surfaces, among said plurality of security surfaces, said overlapping security surfaces being movable with respect to each other; (c) a plurality of single circuit loops, each of said loops themselves comprising a combination of mutually connected conductives strips of individual security surfaces, a connection of these security surfaces occurring through said foil bridges; and (d) a main alarm line having as an input thereto each of an output of said single circuit loops.
Claim 2
Independent Claim
123 words
A system for interconnecting a plurality of security surfaces into a main alarm line, comprising: (a) a strip of electrically conductive foil placed about the periphery of each of a plurality of security surfaces; (b) a plurality of foil bridges, each of said bridges installed between adjacent, partially overlapping security surfaces, among said plurality of security surfaces, said overlapping security surfaces being movable with respect to each other; (c) a plurality of single circuit loops, each of said loops themselves comprising a combination of mutually connected conductives strips of individual security surfaces, a connection of these security surfaces occurring through said foil bridges; and (d) a main alarm line having as an input thereto each of an output of said single circuit loops.
Claim 3
Dependent Claim
75 words
The system as recited in claim 1 in which each of said plurality of foil bridges comprises: a first base including a means for attachment to a first security surface; a second base including means for attachment to a second security surface, said second surface being mutually movable with respect to said first surface; a pair of contact arms mounted on the first base; and a pair of contact receptors mounted on the second base.
Claim 4
Dependent Claim
26 words
The system as recited in claim 2 in which both of said contact receptors is further provided with a supplementary bridge mounted in electrical connection therebetween.
Claim 5
Dependent Claim
26 words
The system as recited in claim 2 in which both of said contact arms is further provided with a supplementary bridge mounted in electrical connection therebetween.
Claim 6
Dependent Claim
31 words
The system as recited in claim 2 in which said system further comprises a protector cover adapted to fit upon the first base in order to protect the contact arms thereof.
Claim 7
Dependent Claim
25 words
The system as recited in claim 3 in which said pair of contact arms, the pair of receptors and the supplementary bridge comprise conducting material.
Claim 8
Dependent Claim
25 words
The system as recited in claim 5 in which said first base, the second base, and the protector cover are made of moldable insulating material.
Claim 9
Dependent Claim
34 words
The system as recited in claim 2 in which said pair of contact arms further comprises a leaf spring shaped element at one end and flat at the other end of each contact arm.
Claim 10
Dependent Claim
40 words
The system as recited in claim 8 in which said pair of contact receptors further exhibits a circular shape, the same being capable of electrical connection by suitably overlapping with the opposite end of said leaf spring shaped contact arm.
Claim 11
Independent Claim
108 words
A method for interconnecting a plurality of security surfaces into a main alarm line, comprising the steps of: (a) Placing a strip of electrically conductive foil about the periphery of each security surface; (b) installing a foil bridge between adjacent, partially overlapping security surfaces which are movable with respect to each other; (c) mutually connecting said peripherally disposed conductive strips of adjacent security surfaces so as to form a single circuit loop from the conductive strips of said adjacent security surfaces, said connection of adjacent surfaces occurring through said foil bridges; and (d) connecting the output of each of said single circuit loops to the main alarm line.
