  • the angular position of the handle portion 92 is just such that a user, the counter-grip member 46 and the handle portion 92 with a Can hold hands, so that the clamping and spreading device according to the invention 10 is operated with one hand.
  • a release element 108 which is pivotable in the Housing 28 is arranged.
  • it is pivotally mounted on the handle element 90.
  • a corresponding pivot bearing. about a recess 110 in the housing 28 may be a user on the release element access and move this.
  • the release element 108 has a first tab 112, with which it on the second actuator 72 may act on one side of the actuator 72, which faces the contact surface 36. Further points the release element 108 a second tab 114, with which it on the first Actuator 70 may act, on a side which of the contact surface 36 turned away.
  • the first tab 112 of the release element 108 is located the second tab 104 of the handle member 90 opposite. Through the release element can the second actuator 72 from a Verkippungs sued to solve. The same applies to the first actuating element 70 via the Tab 114.
  • Through the release element can be a blocking position of the corresponding Actuator 70 or 72, when it is in a locked position, be repealed to move the slide 12 "by hand” can or a clamping position or spread position with respect to workpieces to be able to solve.
  • the actuator 70 in Direction of the contact surface 36 are tilted to cancel the blockage.
  • the release element 108 is in particular formed in one piece.
  • the tabs 112, 114 are relative to the slide rail 12 on opposite Pages. As a result, by a pivoting movement in one direction a Solution of the slide can be achieved, regardless of whether the positioning element 52 in its first position 54 or in its second position 56 is.
  • the rotary switch 64 of the switching device 52 is in such a position the positioning element 52 is in its second position 56 (FIG. 4).
  • the second actuating element 72 abuts against the associated contact surface 82 and is tilted relative to the slide rail 12. This is the mobility the slide rail 12 is locked in the spreading direction 32.
  • the first actuator 70 is in such a position that a displaceability in the Clamping direction 30 is released. Basically, by pressing the slide rail 12 in the tensioning direction 30 this moved in the clamping direction 30 become.
  • the grip element 90 with the first tab 102 act on the actuator 70, in order for a driving of the slide rail 12 in the clamping direction 30 to care.
  • FIG. 5 shows a position in which the grip element 90 is related to a starting position in the direction of the slide rail 12 is pivoted.
  • the first tab 102 of the handle member 90 acts on the first actuator 70 and tilts and moves this.
  • the springs 74a, 74b pressed together. Due to the tilting and movement of the actuator 70, the slide rail 12 is taken in the clamping direction 30 (While the actuator 72, the displaceability in the opposite direction 32 blocks).
  • the springs 86, 88 between the two actuators 70, 72 ensure that just a tilt or tilting of the actuator 70 is allowed to take along the slide rail 12.
  • the restoring force causes the springs 74a, 74b that the handle member 90 returns to its original position.
  • the first actuator 70 then returns to its in the Figure 4 shown starting position back, but with the slide rail 12 to a corresponding piece is displaced in the clamping direction 30.
  • the positioning element 52 starting from the second position 56 in the first position 54th be moved and in this position 54, for example by locking be fixed.
  • the ratios compared to those explained in Figures 4 to 6 Case turn around in that now the first actuator 70th acts as a blocking element and the handle element 90 on the second actuating element 72 is acted on the shift operation.
  • the release element 108 the blocking effect of the first actuating element 70 can be cancel.
  • the operation is basically the same as above based on the second position 56 described.
  • the tensioning and spreading device 10 can be easily Make way. The number of parts needed can be kept low.
  • the Displacement and locking mechanism can be mounted easily.
  • the positioning element 52 which in particular designed as a spring cage is, can be between a spreading or a clamping operation switch accordingly by the positioning member 52 in the first Position 54 or in the second position 56 is positioned.
  • the shift on the slide 12 can be easily between them Switch positions 54 and 56.
  • a single handle member 90 can be (depending on the position of the positioning 52) perform either a spreading or a clamping operation.
  • a single handle member 90 with a single pivot actuation direction can the slide 12 is either in the clamping direction 30th or move in the spreading direction 32.
  • the arrangement of the handle member 90 with respect to the slide is in principle freely selectable, so that an optimized ergonomic design is possible.
  • a counter-grip element (the counter-grip element 46) can be align along the slide rail 12. This in turn makes it possible for the Slide rail 12 in the mating handle member 46 for the Gleitverschiebrete to store.
