Definitions

• a wire tensioner consisting of a polygonal bolt with a slot opening for the wire reception and an overturn protection against the return is known. It is designed to tension individual wires without interrupting them, an advantage that the dominant tensioner does not have.
• one end of the wire on an oval flat iron housing must be pulled through a hole and looped with a special tool, while a transverse axis of rotation with a hole receives the other end of the wire and only winds it around the axis.
• the counter pressure generated in relation to the entanglement necessitates a large number of tensioner sizes which, with the perforated wire guide in the flat iron housing, also do not allow barbed wire to pass through.
• the tensioner mentioned first cannot connect any wires to one another and inevitably tilts to the side, since there is no means around which
• the known clip-on clamps are not able to automatically hold the wire to be clamped.
• the object of the present invention is to remedy the known disadvantages by means of a simple construction and, among other things, also enable the direct tensioning of barbed wire.
• the wire tensioner according to the invention is designed to tension loose but entire wires at any point; it is also able to connect two wires to one another and to tension them.
• a clamping body consisting of one piece and advantageously made of die-cast light metal is inexpensive to manufacture and rustproof. For strong wires such as wire ropes, non-cutting production by drop forging is recommended.
• the tensioning body is made from a polygon, which represents the wire winding axis and in which one end is shaped into a round or square disk. The outside diameter of the disc is at least twice as large as the polygon.
• the washer When tensioning, the washer forms a kind of stabilizer to hold the tensioning body at right angles to the wire when tightening.
• the washer also has two staggered openings on both sides of the polygon, so that two angled wire ends can be brought into one opening from each side, thus connecting two wires.
• An auxiliary tool is attached to the free end of the polygon, e.g. a socket wrench with a ratchet to turn the wire evenly from two sides with a left or right turn to wind the upwind axis.
• the economic importance lies mainly in the quick tensioning of whole wires.
• the tensioner picks up the entire wire through a slot
• the tensioner Since the wire behind the disk must be in the winding axis, the slot is deepened into the polygon. The width and depth of the slot depends on the maximum wire thickness that the tensioner should accommodate. According to the invention, the tensioner is particularly characterized by free wire access to the axle hole, but this is "locked” as soon as a rotary movement takes place after the description. To ensure that even thin wires are held in place and have no play in the axle hole, the polygon is given a rounding at the point at which it abuts the disk. This is designed as a conical outer surface to the axle hole and presses the wire against the hole wall before the wire winds upward around the wind-up axis on the disk.
• the polygon can be partially or completely hollow.
• a locking device is provided so that the wire does not rewind under load. It can be designed as an angled leg strip on one side or as an angled rondelle which has an opening in the middle. This corresponds to the polygon, can be slipped on and cannot be rotated, whereby there are round recesses on the short angled leg, into which the wire is inserted by more or less tightening.
• FIG. 1 shows a wire tensioner according to the invention in front view
• FIG. 2 shows the wire tensioner according to FIG. 1 in plan view
• FIG. 3 shows a blocking member from one end face, and Fig. 4, the locking member in plan view. 1 and 2, 1 means a round disk which is attached to one end of the polygon 2.
• the whole consists of one piece and is made, for example, of light metal injection molding or drop forging.
• the disc is divided into two parts by a slot 3.
• the slot enables a complete wire to be fed freely to the axle hole 4.
• the radius 7 reinforces the polygon 2 at the axle hole and forms a "conical" outer surface in order to hold the wire more firmly in the axle hole 4, the securing being carried out by a rotary movement.
• An auxiliary tool for example a socket wrench with ratchet, is attached to the winding axis 6 in order to wind the wire around the axis with a left or right turn.
• the entire wire which is tensioned as explained, is not shown in the drawing, but the composition and tension of two wires are shown.
• the angled wire ends 13 of the wires 8 and 9 are shown in the offset recesses 5 in the disk 1. Similar "recesses 5 'are also provided in the slot 3 itself. The two wires twist into one another from two sides around the upwind axis as soon as the rotation takes place.
• FIG. 3 and 4 shows with 10 a locking element in L-shape, which has an opening 11 on the long leg, which can be pushed onto the polygon 2 and cannot be rotated.
• the angled leg has the recesses 12 on the side and the recess 14 above, where the Wire is hooked in by more or less suit.
• a rondelle can have a large number of recesses on the outer edge.
