BESGHREIBMG

The present innovation relates to a rope, cord or wire tensioner, in particular a wire tensioner for fencing made of wire mesh and / or the like.

It is known that it is often necessary to use ropes, | To tension cords, wires, etc., which is a common application when setting up metal fencing and the like. To carry out this work are usually elementary devices are used, where els main disadvantage is either cutting The wire or the like to be tensioned or the introduction of a wire or the like on one side of the tensioner And the pulling of the wire or the like from the other side is felt, which in any case is long and difficult Brings processes that lead to a loss of time and great skill on the part of the user require.

Furthermore, the known tensioners require the manufacture of those usually attached to the body of the tensioner Gown to prevent the tensioned wire from unwinding or the like. Long separate manufacturing steps, • consequently a significant increase in manufacturing costs of the finished tensioner.

The task of the present innovation is therefore in the development of a known tensioner and in particular in the creation of a wire tensioner that is based on the already Mounted wire can be placed without the wire being cut or inserted into the tensioner must be, and in which the locking means for locking

hindrance of the unwinding of the wire integral with the

Tensioner assembly formed without long manufacturing steps can be.

Within the scope of the above-mentioned task there is a special one The aim of the innovation is to create a tensioner which the actuating and / or winding body is stable with the support plate is connected and in particular from

! ι this cannot solve, so another backup

is offered to the user in use.

Last but not least, one aim of the present innovation is to create a tensioner that is particularly cheap and starting of possibly plasticizable and / or galvanizable. Metal material can be produced.

The above task and the stated goals and further goals, which will appear clearly below, are indicated by a tensioner especially for fencing of metal mesh and / or the like. Released or achieved, which comprises an elongated plate which is in essentially centrally a generally circular opening which forms a winding cylinder for the to be tensioned Wire o, the like, forming actuating body rotatable and further a shaped portion for engagement with a tool for rotating the aforesaid Has body, the plate tongues to attack the wire to be tensioned o. The like. Opposite Forms sides of the actuating body and the tensioner is characterized in that locking means for preventing with the plate and the cylindrical body the rotation of the body in the unwinding direction of the wire

Further features and advantages of the tensioner according to the innovation emerge more clearly from the following detailed Description of the same, for example, and

rungsgemasse, denoted overall by the reference number 1-fce Rope, cord or wire tensioner on an elongated plate 2, which is advantageous but not necessarily having rounded long ends.

In a central portion of this plate 2 is a

substantially circular opening formed in which is the cylindrical "actuating" or Clamping body rotatably mounted is. The cylindrical actuating body 3 forms on one side of the plate 2 a substantially cylindrical section 4 for winding the wire 5 o, the like., The section having a diametrical incision 6, which extends in the longitudinal direction for engagement with the wire 5 or the like to be tensioned.

On the other side of the plate 2, the actuating body 3 forms a shaped section 7, which is advantageously polygonal, for example square _9, with one of tongues or teeth in the vicinity of the area of engagement with the plate 2 in the vicinity of the shaped section of the actuating body 3 8 formed rotation lock is formed, wherein the tongues or teeth on the one hand a stop surface 9 and on the other hand have a rounded sliding surface.

Tongues 11 are formed on the plate 2 in the region of a longitudinal edge, for example by punching opposite sides are arranged with respect to the Aktkör by 3 and with the wire 5 to be tensioned o, -like get into engagement and in fact a seat for storing and sliding the wire or the like itself form.

According to the innovation, the plate 2 in the vicinity .der said opening has a protruding deformed area, which is denoted by the reference numeral 12 and is integrally formed with the plate, wherein

the stop surface 9 of one of the teeth or ribs 8 already mentioned strikes against this area. on in this way, this stop engagement prevents the rotation of the actuating body 3 in the unwinding direction of the Wire 5 or the like, hence the definition of the wire o. The like. For the purpose of preventing the sagging can be obtained by a simple expression 12, which for example can be generated quickly by stamping processes known per se. This eliminates the need for the lever of the known tensioner, with consequent economic advantages due to a considerable reduction in production times be achieved.

According to a further aspect of the innovation, provision is made for the actuating body 3 to exit from the centrally formed in the plate 2 opening is prevented. For this purpose the lobes of the incision were made slightly spread outwards so that they diverge and thus prevent the actuator body 3 from escaping. It goes without saying that this expansion process is carried out after the essentially cylindrical section has been imported of the actuating body 3 into the opening of the plate 2 carried out. In this way, the actuator 3 cannot be pulled out of the opening and detached from the plate, which in fact occurs when using the tensioner on metal fencing is very useful.

The way of using the tensioner according to the innovation is extremely easy. It is sufficient to insert the wire 0 to be tensioned into the incision 6 of the cylindrical section 4 to be introduced and inserted into the seats formed by the tongues 11.

After these storage processes, it is possible to use the To rotate the body 3 in such a way that the wire or the like. winds up on the cylinder and is thus tensioned.

Then, with the rotation of the body 3 in the unwinding direction continued "until the desired voltage" or the the desired tension of the wire or the like has been achieved? after that it is sufficient to set it in the desired position simply the engagement of the stop section 9 of a tooth 8 on the corresponding stop surface of the projection 12 to "cause.

It should be added to the above remarks that the Rotation of the entire tensioner and in particular the plate 2 is prevented by this thanks to the presence of the two tongues 11 with the wire or the like. In engagement, the tongues 11 due to their arrangement on opposite Pages of the actuator body 3 stresses that try to rotate the plate in two opposite directions and consequently one Do not allow rotation of the plate itself.

From the above you can see how the innovation the intended goals fully achieved; in particular, the extreme structural simplicity of the tensioner and its easy operability, which can be achieved by any is feasible with the above-mentioned shaped portion engageable tool. As already mentioned, the tensioner is used on wires 0, etc. that have already been installed, and on any of them Place the same without any cutting operations

breaking or the import of wires or the like hundreds of meters (with the risk of damaging the wire or the like).

Another essential feature of the innovation is that the tensioner has very few manufacturing steps and can be produced in an extremely short time, since the unwinding of the wire o. preventing means are integrally formed with the plate-shaped body of the tensioner, whereby the tensioner especially cheap to admit. In the practical implementation of the innovation, the materials used as well as the dimensions and respective shapes can be selected as required, provided that that they are contractual with the respective application. In particular, appropriately treated metal materials can be used be used, which are subjected to a subsequent plasticization.
