Abstract

Telescopic strut for large arrows, characterized by the fact that it consists of a base tube provided with a foot and with the upper rim open to cover another tube of slightly smaller caliber and with a smooth surface and which, in turn, is capable of being clad another tube of smaller caliber, whose upper end a support plate, being arranged in the curb of the main stem and duly welded, according to generatrix, a drill and threaded sleeve for screwing a ball-head bolt, in which it fits and supports the concavity of a countersunk central eye type washer, so that in its threading in the secondary tube, by which it can be moved parallel and wedged in an inclination of its axis, which is achieved in the support on the spherical head of the bolt, maintaining this inclined position fixed by tangential forcing a wire ring, also threaded in the secondary tube, above the cup, and provided with prolonga or tail adial, which is elastically hooked into an eyelet fixed on the side of the cylindrical outer body of the main tube, thereby blocking the exit and entry of the secondary tube with respect to the main and composing the first phase of the strut, which can be extended embedded in the secondary tube, and above the upper support plate, threaded a band of diameter coinciding with that of the secondary tube and resting on the plate itself, whose upper mouth is cut in an inclined plane at an angle greater than that of wedging the cup. Drag that, threaded in the tertiary tube, rests on its concavity against the top of the band, creating the precise wedging to fix the entry and exit of the said tertiary tube with respect to the secondary, with position ensured by the forcing created by another ring of wire with elastic glue, which is hooked in blind grommet on the surface of the plate and supporting the secondary tube, blocking the mu positions these allow the refining of the distance of the final support thanks to the bolting of the bolt that pushes, coined, the secondary pipe and, with this, the tertiary of the felling in the advance that marks the filleting of the latter.
