Abstract
A wire fence includes a plurality of wires tensioned at their opposite ends by ground-anchoring means each comprising a pair of vertical posts anchorable in the ground in spaced parallel relationship, and a diagonal post secured between the lower end of one vertical post and the upper end of the other, so that the diagonal post extends at an incline between the two vertical posts. The fence includes trip-wires secured to the diagonal post and freely movable in the longitudinal direction with respect to the vertical posts. The trip wires are connected to a detector which is actuated upon the disturbance of a trip wire.
Claims10
A wire fence including a plurality of trip-wires tensioned between ground-anchoring means at their opposite ends and connected to detector means actuated upon the disturbance of the trip-wires, characterized in that said ground-anchoring means comprises a pair of anchoring posts anchorable in the ground in spaced parallel relationship, and a diagonal post secured to said anchoring posts so as to extend at an incline therebetween with respect to the ground, said trip-wires being secured to said diagonal post and being longitudinally freely movable with respect to said anchoring posts, thereby increasing the difficulty of one attempting to climb over the fence by depriving him of a substantially horizontal foot-engaging surface and a good hand-gripping support, the weight of one attempting to climb the fence producing a large displacement of the trip-wires secured to the diagonal post thereby better assuring that the trip-wires will actuate the detector.
A wire fence including a plurality of trip-wires tensioned between ground-anchoring means and connected to a detector for actuating same, characterized in that said ground-anchoring means comprises a pair of vertical posts anchorable in the ground in said spaced parallel relationship, and a diagonal post secured between the lower end of one of said vertical posts and the upper end of the other of said vertical posts so as to extend at an incline therebetween with respect to the ground, said wires being secured to said diagonal post and being longitudinally freely movable with respect to said vertical posts thereby increasing the difficulty of one attempting to climb over the fence by depriving him of a substantially horizontal foot-engageing surface and a good hand-gripping support;
- the weight of one attempting to climb the fence producing a large displacement of the trip-wires secured to the diagonal post, thereby better assuring that the trip-wires will actuate the detector.
