Description

Wire tensioner The invention relates to a wire tensioner with a winding part for winding up wire and a fixing for fixing of the winding part in its position after winding the wire.

For tensioning wires, especially fencing wires from vineyards, Vineyards, agriculturally or industrially used land as well Wire tensioners are used for residential lots and other properties; A wire tensioner with advantageous properties is in the German utility model DBGM 1 987 939 (37 f, 11/06). This wire tensioner has two winding arms in addition to a tensioning arm which allow the winding of wire and are so different in level, that the free Viickelarm protrudes slightly over the tension arm. This makes one special strong, reliable training of the wire tensioner guaranteed.

The present invention aims to provide a wire tensioner, which, like the wire tensioner described, has a particularly simple structure, but an even more precise tensioning of the wire with orutel) enables operational reliability.

According to the invention is a wire tensioner with a winding part for Winding up of wire and a lock for locking the winding part in its position after the winding of the wire provided, and the invention is characterized in that the winding part as an elongated R extends transversely to the Direction of the tensioned wire extending body is formed on the at least two locking parts designed as an elongated body are arranged, each of which include approximately a right angle with the winding part and one with the other Include angle which is between 450 and 1350, preferably at 90 °, wherein each locking part individually on the tensioned wire for the purpose of determining the winding can attack.

According to a preferred embodiment of the invention is at least one of the locking parts so long that it can be used as a lever for winding the wire can be. A particularly robust and reliable training results when the wire tensioner in a manner known per se from a single one, several times in a corresponding manner Curved wire of suitable diameter is best.

According to a further advantageous embodiment, there are at the ends the locking parts arranged hooks, which on the tensioned wire for the purpose of locking can attack the winding. However, it can also be useful that one or both locking parts for attaching a special hook or similar

Like. Are formed, which on the tensioned wire for the purpose of Feststeiling can attack the winding. You can use either of the two locking parts at the end, e.g. by striking, by training as a triangle or square, etc., like this design so that a hmable hook can be attached non-rotatably.

Embodiments of the invention are based on the Description of the drawing: FIG. 1 shows a first preferred embodiment the finding in which the two clamping arms have the same length.

Figure 2 shows a further embodiment of the invention in which the clamping arms have different lengths.

FIG. 3 shows an exemplary embodiment of the wire tensioner according to FIG Invention, which after winding up the excess wire so on the tensioned Wire attacks that the winding part is determined.

FIG. 4 shows a further preferred embodiment of the invention with a detachable hook.

As Figure 1 shows, the wire tensioner according to the invention consists of two winding arms 1 and 2, which run approximately parallel to each other or preferably enclose an acute angle with each other and connected to each other at one end are. At the free ends of the two winding arms 1 and 2 close approximately at right angles Clamping arms 3 and 4 on. As already described in the utility model mentioned at the beginning is, it can be useful that the wrapping arms 1 and 2 so different in level are that one of the two winding arms 2 protrudes slightly beyond a tensioning arm 3, so that the wire is safely guided and held during the tensioning process. In order to enable a particularly advantageous holding of the wound wire, wrapping arm 1 and tensioning arm 3 form approximately a right angle, but this is at right angles Angle preferably below 900, while the angle arm 2 forms an angle of approximately 900 with the tensioning arm 4, but preferably this angle is also below 900 at the ends of the two clamping arms 3 and 4 there are hooks 5 and 6, respectively, through which the tensioning arms are attached to the tensioned wire can attack for the purpose of determining the winding.

While in the embodiment of Figure 1 useful in known Way a key is used on the U-shaped connection of the two Wrapping arms 1 and 2 engages, is in the exemplary embodiment according to FIG such use of a key is not required, since clamping arm 7 is such Has length that it can serve as a lever when winding the wire. The other Tension arm 8 k have the normal (or also an enlarged) length at the end the clamping arms 7 and 8 are just as in the embodiment according to FIG Figure 1 hooks 9 and 10 to determine the winding.

Figure 3 shows how the wire tensioner according to the invention for winding and tensioning a wire 11 can be used.

Before winding is the one consisting of the winding arms 1 and 2 Winding part has been pushed onto the wire 11 and then the winding part is 1, 2 either with the help of a key or by direct manual operation Attack on one of the clamping arms 3 or 4 (8 or 9) on the excess wire the winding part 1, 2 has been wound up. If the wire 11 then according to the appropriate Winding has received the required tension, the wire tensioner is moved in such a way that that one of the hooks 5 or

6, in the present embodiment the hook 6, on the tensioned Wire attacks. The wire tensioner then remains through the elastic Tension of the wire 11 in the position shown.

This position can then be changed appropriately if necessary to back up.

In that, according to the invention, two clamping arms 3, 4 and 7, 8 are used which include an angle of about 900, it is possible according to the invention, lock the wire tensioner after a quarter turn, so that a very sensitive tension of the Wire 11 is possible.

A preferred embodiment is shown in FIG. 4. In this embodiment too the winding arms 1, 2 form a winding part, and tensioning arms 12, 17 are in the position already described at the ends of the wrapping arms 1, 2 present. To the However, there are no hooks at the ends of the tensioning arms, rather the ends are like this designed that a removable hook 15 can be placed on them. Like figure 4 shows, there is a stop 14 at the end of the tensioning arm 12, and a similar one The stop can also be present at the end of the clamping arm 13.

On the ends of the clamping arms 12 and 13, depending on your needs removable hook 15 are pushed. The removable hook 15 is preferably made from a slip-on clip 16, a lever part 17 and an end hook 18.

In a manner similar to that described in connection with FIG the wire tensioner according to FIG. 4 is pushed onto the wire 11 to be tensioned and rotated will. It is again possible to do the rotation with the help of one on the wrapping arms 1, 2 held keys, or you can use the detachable hook Slide 15 onto one of the ends of the tensioning arms 12, 13 and rotate without assistance of a key.

When the wire is then suitably tensioned, the Detection with the aid of an attached hook 15, which is then in this position remains.

Instead of the stop 14, which for manufacturing reasons is particularly useful, other types of anti-twist attachment can also be used of the detachable hook 15, for example a triangular or square shape. The anti-twist device can also be dispensed with if the hook 15 or

the end hook 18 is designed to adhere firmly to the wire.

The embodiment described according to Figure 4 has the advantage that they just like the embodiments shown with reference to FIGS. 1-3 very precise and sensitive adjustment of the wire tension by a quarter turn allows, on the other hand, but the hook-shaped end 5 (Fig. 1, Fig. 3), which is not required to determine the winding, is omitted.

The invention is not limited to the illustrated and described exemplary embodiments limited. In particular, it is possible to use the hooks 5, 6, 9, 10 and the end hook 18 in another suitable manner in order to perform its function of determining the To improve winding, for example in such a way that locking elements, eyelets or the like. are formed. It is also possible to tension the wire even more precisely in addition to the tensioning arms 3, 4 or 12, 13, one or more additional tensioning arms to be provided.

It is also not necessary that the angle that the clamping arms 3, 4 or 12, 13 include each other, is exactly 900, but you can do this Angle also vary appropriately, however, it will preferably be between between 450 and 1350.
