Trip-wire guiding device and protective fence including same

A trip-wire guiding device for a protective fence including a plurality of trip-wires tensioned between a pair of fence poles and connected to detector means for actuating same upon the disturbance of said trip-wires by an attempted penetration of the fence;

• said trip-wire guiding device including a ground-anchorable mounting pole having a stake at its lower end insertable into the ground between said pair of fence poles, an elongated trip-wire guiding means, and force-yielding attaching means attaching the elongated guiding means in a spaced, force-yielding manner to and laterally of said mounting pole;
• said elongated trip-wire guiding means comprising an open-spiral rod having lateral spaces between adjacent spirals which spaces serve as longitudinally-spaced openings through which said trip-wires are to be passed by sidewise insertion for maintaining them in parallel space relationship;
• the axial space through all the spirals constituting an axial channel extending longitudinally through the open-spiral rod;
• and a common locking member received in said axial channel of the open-spiral rod for locking the trip-wires against removal through the lateral spaces between adjacent spirals, while permitting free longitudinal movement of the tensioned trip-wires such as to cause the detector means to be actuated upon a change in tension in the trip-wires;
• said force-yielding attaching means including a plurality of short rods attachable at one end to said ground-anchorable mounting pole and formed with eyes at their opposite ends disposed in the spaces between adjacent spirals of the open-spiral rod, said elongated trip-wire guiding means further including a second straight rod passed through said axial channel through the open-spiral rod and through the eyes of the plurality of short rods.
