Definitions

  • the invention relates to a hand pressing pliers for pressing Pipe connections, with two handles that can be moved against each other and two press jaws forming a press die, one of which this press jaw is rigidly attached to one of the handles and the other press jaw is pivoted to this handle and connected to the other handle via a support joint is, the two handles each over another Support joint are pivotally connected to a pressure lever and this push lever with the movable handle a toggle lever drive forms.
  • Hand pressing pliers of the type mentioned are from DE-U-298 07 065 of the applicant and from DE-A-197 09 639 become known. With such hand pressing pliers can be used to make pipe connections, where a plastically deformable pipe on a fitting is pressed on. When laying cables in building services there is often the problem that the press connections under very tight spaces must be manufactured. Despite the difficult assembly, however, such connections must be reliable can be produced because of high building damage in the event of a leak can arise. Hand pressing pliers have opposite the main advantage of the well-known motorized pressing tongs, that they can also be used in tight spaces. With motorized pressing tongs, however, it is not a problem, the required To apply pressing force. With a toggle drive however, it is also possible with hand crimping pliers, the required To apply pressing force.
  • the task is with a generic hand crimping tool solved that the movable handle has two handle positions has, a front grip position to the die has a much smaller distance than a rear handle position and that the movable handle is in a kinked position is feasible.
  • the pressing tongs according to the invention thus have two handle positions. Can in the front grip position the wide open pressing tongs are also closed with one hand become. However, the pressing force is comparatively in this position small, but it is sufficient to attach the pressing tongs to the To put on the pipe and essentially close it.
  • the rear one Handle position enables a comparatively long lever arm and can be gripped with one hand when the movable Handle is kinked.
  • the two handle positions on the movable handle are preferred formed by handle protection parts that move on these Handle are attached. These enable a comfortable and secure holding of the hand pressing pliers.
  • this articulated lever at the kink with one Interlock provided that when transitioning from the kinked in the extended position automatically locks this lever.
  • the swivel position can be restored be solved.
  • the automatic locking results in a very cheap handling, which only needs one hand.
  • the invention also relates to a method for pressing a pipe connection with a hand crimping tool.
  • the hand pressing pliers 2 shown in Fig. 1 has pressing jaws 6 and 7, which form a die 5.
  • the press jaw 6 is firm connected with a handle 4, which is a lever with a length of, for example, 28 cm.
  • a Handle protection 4a is placed, which has a length of 28, for example cm.
  • This handle guard 4a is made of plastic, for example manufactured and extends from the extreme end of the Handle 4 to at least one support joint 13 on which a Push lever 16 is articulated.
  • the press jaw 7 is connected to the handle 4 via a swivel joint 10 and via a support joint 12 with a movable handle 3 connected.
  • This handle 3 is in turn via a support joint 14 connected to the pressure lever 16.
  • the joints 12, 13 and 14 and the pressure lever 16 and the front region of the handle 3 form a knee joint, which is reaching a high Press force enables.
  • the movable handle 3 is designed as an articulated lever and has a front lever part 3a and a rear lever part 3b on. Both parts 3a and 3b are by means of an articulated joint 20 connected together. This articulated joint 20 enables one Bending the handle 3. In one position according to FIG. 2 are the two lever parts 3a and 3b essentially on one arranged in a straight line, as was previously the case. In the kinked 3 is the rear lever part 3b a swivel 21 bent at an angle. This angle • is much larger than 45 degrees. So this is about a comparatively small kink.
  • the articulated joint has a connecting part according to FIGS. 2 to 4 23 on, for example with two bolts 22 with the Handle part 3a is connected.
  • this connecting part 23 With the handle part 3b is this connecting part 23 with the axis 21a (FIG. 4 of the swivel joint 21) connected.
  • This Elongated hole 26 runs transversely to the longitudinal direction according to FIGS. 2 and 3 of the connecting part 23.
  • the elongated one shown in FIG Position is by a lower stop of the pin 25 in Elongated hole 26 determined while in the kinked position shown in Fig. 3 determined by an upper stop on this slot 26 is.
  • the extended position shown in Fig. 2 is with a latch 27 set of a laterally projecting operating part 27a and an engagement part 27b.
  • the engaging part 27b extends into a recess 24 of the connecting part 23 and can be placed against a shoulder 24a of the recess.
  • To postpone of the bolt 27 on the actuating part 27a it can against the retroactive force of a compression spring 29, in that shown in Fig. 3 retracted position.
  • the compression spring 29 is at one end on the bolt 27 and at the other end on a bolt 28 supported. 3 is the Latch 27 against the connecting part 23 by the compression spring 29 curious; excited.
  • the handle part 3b is bent by the one shown in FIG. 3 Brought into the position shown in Fig.
  • the handle 3 has two handle positions 8 and 9, each are formed by a hand protection part 8a or 9a.
  • the Grip position 8 is essentially between the articulated joint 20 and the support joint 12 and its length is comparative short and is for example about 10 cm.
  • the Handle position 9 forms a rear position and is located behind the articulated joint 20. Both grip positions 8 and 9 are as can be seen, clearly differentiated from one another.
  • the front one Handle position 8 has a much smaller to the hinge 10 Distance to than the rear handle position 9.
  • This rear Handle position 9 is, as can be seen, also much longer than the front handle position 8 and is for example 20 cm.
  • the front handle position 8 is dimensioned so that it is comfortable can be gripped with one hand while the rear Grip position can be gripped with two hands.
  • the grip position the lever 4 is, as can be seen, about as long as that two handle positions 8 and 9 together.
  • the hand pressing pliers 2 are now pressed according to FIG brought suitable swivel position.
  • the bolt 27 for Disengaged the lock postponed Now the handle 3 is on the rear handle position 9 and the handle 4, like the Fig. 8 clearly shows.
  • the handle 3 is kinked here what grasping with one hand enables.
  • the two handles 3 and 4 are now gripped and pressed together according to FIG. 8.
  • the Pressing force is applied to the knee joint as mentioned above transfer two press jaws 6 and 7, which the tube 1 at least partially deform.
  • the handle part 3b according to FIG brought the extended position according to FIG. 2. This is through a simple swivel movement is possible, as already explained above the articulated joint 20 is automatically locked.
  • the Crimping tool 2 is now with both hands on the handle as shown in FIG. 10 4 and gripped at the handle position 9. With this grip position a long lever is available and one can high pressing force can be exerted.
  • the two levers 4 and 3 as shown in FIG. 10 are completely laid against each other. The Connection is established and the pressing tongs 2 can be opened and be removed from tube 1.
