Definitions

  • a generic clamping tool in the form of a clamp is from German patent application DE 39 17 473 known.
  • This known clamp has one movable jaw, which at the end of a push rod sits. This jaw passes through a housing, which carries a second, fixed jaw. From the case protrudes a handle. By means of a handle that is pivotally arranged on the housing, and which on the Handle can be moved, the push rod be shifted so that the movable jaw is gradually moved towards the fixed jaw.
  • the known clamp On the handling side in the direction of the two clamping jaws the known clamp has a released one Non-return lock in the form of a clamping lever. This should prevent the movable jaw from moving in the opposite direction can be relocated. Stands out with a free end there the lever forming the backstop from the Housing out and can be swiveled around the Release backlash. In the released position the two jaws can move in the opposite direction move apart.
  • Another clamp is from GB 21 78 689.
  • the Manageability of this clamp is similar to that of the utility model 87 03 379.8.
  • the invention has for its object a generic Advantageously to further develop the clamp.
  • the invention provides that the leverage ratios of Lever transmission can be changed depending on the load.
  • leverage ratios of lever transfer in that the displacement path of the jaw becomes smaller and thus follows the leverage law applicable force is increased.
  • the relationship between loadarn and power arm of the lever transmission in favor of an enlarging when the load occurs Tension variable.
  • the changing leverage ratios are preferably realized in that the active arm, which is on the pull or push rod acts, a shortenable arm of an operating lever is.
  • the shortenable active arm can be an application surface the slider.
  • the shortening of the active arm is achieved in that the actuating lever has a changeable bearing point trains.
  • the clamp has a first jaw 1 and a second jaw 2.
  • the first jaw 1 is via detachable connections, e.g. plug connections, Screws or the like with one end 3 'of Pull or push rod 3 firmly connected.
  • the jaw 2 has a stepping gear housing which of the Push rod 3 is penetrated.
  • the stepper gearbox continues in one Handle part 33.
  • Adjacent an arm protrudes from the gear housing 10 a release lever 15, which by means of a Compression spring 34 is cushioned against the housing.
  • In the rest arm acts on the active arm 18 of the release lever 15 a stationary stop 35.
  • the active arm 18 has a cavity through which the train or Push rod 3 runs.
  • Parallel to the arm 18 of the Release lever 15, which is pivotable about the bearing pin 16 is, a locking slide 14, on which its return side 19 engages a return spring 17 and the locking slide 14 against the direction of displacement the pull or push rod 3 is applied.
  • the opposite side 20 of the locking slide 14 rests in the rest position against a fixed stop 24.
  • the driving slide 5 has as well as the locking slide 14 an opening through which the train or Push rod 3 protrudes. Just like the corresponding opening of the gate valve 14 has the opening of Driving slider 5 edges to deal with the train or To be able to tilt the push rod 3.
  • the driving slide 5 is by means of a compression spring penetrated by the pull or push rod 4, which is supported on the stops 35 pressed against the stops 22, 23 such that the Push rod 3 freely through the opening of the slider 5 can slide.
  • the preload of the slider and the associated cant with the narrow edges of the pull or push rod 3 is one Displacement of the push rod 3 only in the direction of the arrow possible.
  • the locking slide 14 can just as the Mitnahineschieber 5 opposite by manipulation in the direction of the arrow be moved to the housing.
  • the relocation of the Locking slide 4 takes place by actuating the release lever 15.
  • the release lever 15 is in front of the handle 10 that one of his fingers in the free space brought between handle 10 and handle 33, the handle 10 gripping hand can be operated.
  • a release is also possible if a workpiece extends over the push rod 3 and immediately before the flight to the fixed jaw 2 lying handle 33 lies. Especially when the workpiece then comes into contact with the handle 33 is possible if the clamping clamp in the position shown in FIG stretching function shown, the handle can no longer be included.
  • the stretching function turns out to be fleeting Extension to the fixed jaw 2 protruding edge the handle 33 even as advantageous, as this as can serve additional contact surface on a workpiece.
  • This one-sided burden on the release lever 15 causes a tilt 25, 26 to the opposite opening sides of the gate valve 14.
  • the locking slide jams 14 on the pull or push rod 3, so that the push rod 3 against the direction of the arrow from the return spring 17 is taken along so that the two jaws 1, 2nd be moved apart.
  • FIG. 8 works in an identical manner to that in FIGS. 1 to 7 Exemplified embodiment shown, only the housing shape is designed differently and the return spring 17th is somewhat shortened.
  • the bearing pin 16 pivotable release lever 15 fork-shaped and forms an extension 21 which has a stop trains to the opposite side 20 of the gate valve 14 to press against the fixed stop 24.
  • the back of handle 33 goes into a recessed section over from which the push rod 3 protrudes.
  • the embodiment shown is that of the push rod 3 adjacent recessed section lower to Release lever 15 spaced as the back of the handle 33.
