Abstract
Abstract This invention relates to an intrusion warning wire fence secured to spaced supporting poles (2) and comprising one or more electrical and/or optical conductors (8), preferably optical fibres, which may be either incorporated within one or more tubular wires (3) of said wire fence and/or associated exteriorly with one or more wires of said fence, and/or arranged freely in the fence, and which are connected to an intrusion warning system capable of emitting a warning and/or alarm signal in case of breakage or reduction of the conduction capability of at least one of said conductors (8). According to the invention, in order to prevent anyone from stepping over the fence, the latter is extended upwards beyond the upper ends of the supporting poles (2), and this upper unsupported portion of the fence will be either distorted (bent, flexed) and/or broken, at least locally, if anyone tries to step over the fence. Extending in the upper unsupported portion of the fence and/or between this upper unsupported portion of the fence and the suppoting poles (2), and/or between said upper unsupported portion and the underlying portion of the fence which is stretched between the supporting poles (2), is at least one electrical and/or optical conductor (8) which will be either broken or distorted (bent, stretched, crushed) as a result of any breakage or distortion of the upper unsupported portion of the fence, so as to provide a warning or alarm signal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
234 words
1 . An intrusion warning wire fence fixed to spaced supporting poles (2), or the l like, and comprising one or more electrical and/or optical conductors (8), preferably optical fibres, which may be incorporated in one or more tubular wires (3) of the fence and/or applied exteriorly to one or more wires of said fence and/or extended freely in the fence, and which are connected to an intrusion warning system capable of emitting a warning and/or alarm signal in case of breakage or reduction of the conduction capability of at feast one of said conductors, characterized in that said wire fence extends upwards beyond the top ends of the supporting poles (2), and this upper unsupported portion of the fence will be either distorted (bent flexed) and/or broken, at least locally, if anyone tries to step over the fence, and in said upper unsupported portion of the wire fence and/or between said upper unsupported portion of the fence and the supporting poles and/or between the upper unsupported portion of the fence and the underlying portion of the wire fence which is stretched between the supporting poles is arranged at least one electrical and/or optical conductor (8) which will be either broken or distorted (bent; stretched, crushed)as a result of any breakage or distortion of the upper unsupported portion of the Wire fence so as to cause the emission of a warning or alarm signal.
Claim 2
Dependent Claim
234 words
1 . An intrusion warning wire fence fixed to spaced supporting poles (2), or the l like, and comprising one or more electrical and/or optical conductors (8), preferably optical fibres, which may be incorporated in one or more tubular wires (3) of the fence and/or applied exteriorly to one or more wires of said fence and/or extended freely in the fence, and which are connected to an intrusion warning system capable of emitting a warning and/or alarm signal in case of breakage or reduction of the conduction capability of at feast one of said conductors, characterized in that said wire fence extends upwards beyond the top ends of the supporting poles (2), and this upper unsupported portion of the fence will be either distorted (bent flexed) and/or broken, at least locally, if anyone tries to step over the fence, and in said upper unsupported portion of the wire fence and/or between said upper unsupported portion of the fence and the supporting poles and/or between the upper unsupported portion of the fence and the underlying portion of the wire fence which is stretched between the supporting poles is arranged at least one electrical and/or optical conductor (8) which will be either broken or distorted (bent; stretched, crushed)as a result of any breakage or distortion of the upper unsupported portion of the Wire fence so as to cause the emission of a warning or alarm signal.
Claim 3
Dependent Claim
91 words
A wire fence according to claim 1, characterized by mechanical weakening and/or interrupting provisions, either localized or continuous, in the upper unsupported portion of the wire fence extended beyond the top ends of the supporting poles (2) and/or between said upper unsupported portion and the underlying portion of the wire fence stretched between the supporting poles (2), so as to facilitate the breakage or the distortion of said upper unsupported portion of the fence with respect to the underlying portion of the fence in case of any attempt of stepping thereover.
Claim 4
Dependent Claim
32 words
A wire fence according to claim 1, characterized by mechanical weakening or disconnectable provisions, either localized or continuous, between the upper unsupported portions of the fence right above the supporting poles (2).
Claim 5
Dependent Claim
111 words
A wire fence according to claim 1, characterized in that, above said supporting poles (2), the adjacent upper unsupported portions of two sections (1) of the wire fence at the opposite sides of a supporting pole (2) are completely or partly disconnected mechanically from each- other and are connected to each other by means of at least one electrical or optical conductor (8), so as to be displaced from each other and/or to be distorted in case of any attempt of stepping thereover, and so as to break or distort (stretch, bend, crush) said electrical or optical conductor (8) whereby to cause the emission of a signal from the warning system.
Claim 6
Dependent Claim
87 words
A wire fence according to claim 1, characterized in that the two adjacent upper unsupported portions of the fence, which are disconnected mechanically from each other and are comprised in two sections (1) of the fence at the opposite sides of a supporting pole (2), are connected to each other by at least one electrical or optical conductor - (8) passing alternately through some openings of one and the other of said two upper portions and, preferably, is connected as well to the supporting pole (8) therebelow.
Claim 7
Dependent Claim
153 words
A wire fence according to claim 1, formed by individual wire fence panels (1) mounted between supporting poles - (2) and containing at least one electrical or optical conductor (8), the conductors of these wire fence panels being connected to each other at said supporting poles, preferably within said poles (2) which are of box-type construction, characterized in that said supporting poles (2) have a smaller height than said wire fence panels (1), and the latter are completely or partly disconnected mechanically from each other in the upper portions thereof which extend unsupportedly upwards beyond the top ends of the poles - (8), while said electrical or optical conductor (8) connecting two adjacent wire fence panels associated to a supporting pole mechanically interconnects the upper portions of these two wire fence panels (1) above the top end of the supporting pole (2) and, preferably, is connected as welt to said supporting pole (2).
