Description

Pliers-like hand tools For the transmission of adjustment movements, pull cables are often used. This is especially true for. aircraft construction. The known cable thimble, around which the cable end is wrapped and then spliced, has not proven to be suitable for fastening the pull cables to the linkage levers and the like. In general, a collar that is firmly connected to the pull rope is preferred for power transmission for the stated purpose. The fastening of the covenant on a pull rope must be carried out very carefully, taking into account the often considerable adjustment forces. The connection by soldering is often not feasible, e.g. in aircraft construction. In addition, the durability of such connections depends on the quality of the A change in strength due to the effect of corrosion has also to be expected. Therefore, the fastening has been carried out in such a way that the collar provided with a hole corresponding to the diameter of the cable is pushed onto the end of the cable and there by deformation, which causes a reduction in the diameter of the hole, is firmly connected to your rope body between spaces of the rope strands is pressed. To exert the necessary strong forces, large and complicated tools have been common up to now, which are available on the construction site, but are usually not easy to move and, as a result, cannot be carried on board the vehicles, especially airplanes . The consequence is that in remote repair sites such. B. For landings of airplanes on airfields and the like. Such tools are not available.

These disadvantages are eliminated in the present invention. It concerns a pliers-like hand tool for. Attachment of metallic collars on pull ropes, which are suitable for exercising great forces and thereby save space and is partially dismantled so that it can be easily carried.

To this end, the invention seeks, the effect one in one The centerpiece of the adjustable threaded spindle with the interposition of pressure pieces on the long legs of shaped like levers with unequal arms and also - to transfer pincer links mounted on the spindle frog so that at the Zangeiunaul for the purpose of deforming cable bundles There are already pliers-like @, tools in connection with threaded spindles for pushing out of hinge pins from the connecting part of the link chains lleked @ etvor (lcn differ, however, from the object of the invention with regard to the construction, the Mode of action and (go on purpose. The pliers fall into the open to. (read the tool to hold on to all the work places or to draw the opposing forces, while the threaded spindles act directly on the expressing bolt.

The accompanying drawings show an exemplary embodiment (the subject matter of the invention. They show: FIG. 1 a side view in section.

Fig. 3 the fastening device of the handles iili section.

The hand tool for fastened111 <# full ties on pull ropes consists of your heart i, in which the different levers - at 3 are movably mounted. Jaws 4, which are provided with an Ottiiung 5 for receiving the rope bundle, are expediently provided in the press collar. The threaded spindle 6 can move in a corresponding mating thread (los frog). At the upper end, the spindle 6 has a 131-111c17 and an advantageously prismatic head S on which the key engages Furthermore, on the spindle 6 there is: cross head io, which has two pins ii, the pins ii are connected by pressure pieces 12 to the longer lever arms of the lever 2 on which the pressure pieces Oei 13 are rotatably mounted. Handles 14 are provided for convenient handling, which grip with fastening tabs 1s over the legs 2 and are secured by push-button pins i6. In order to be able to easily remove the handles, the fastening pins 16 are equipped with collars 17 and iS, which are inserted into corresponding recesses in the fastening tabs 1 Engage 3. By pressing the button on the pins 16, the pins under the action slide g the spring icg standing parts 17 and IF from their slwrrlage, so that the handles, which have slots 20, can be pulled off over the thinner part of the locking pins 10 and in this way easily removed.

The mode of action is as follows: After you, a covenant over the Seileiicle is scolded. is (the hand tool is brought into action.

so that despite the riitltnlicil I small dimensions of the tool the connection of the covenant with your rope end is made without much effort can be.
