Definitions

  • the invention relates to a pair of pliers, in particular a water pump pliers according to the preamble of claim 1.
  • the legs are like a pair of scissors by means of a Bolt connected, usually bolted to a grooved or a sliding joint. If The bolting has loosened in the course of use, is under force when using conventional pliers of this type skipping one Position in another easily possible, causing damage to the workpiece and / or injury the user can bring about.
  • the slot holes are namely formed by webs or tips, which wear in use. In front all if during the closing movement of the hinge pin between two Detent positions, awkward force can be a high edge pressure cause, leading to the widening and rounding of the locking webs.
  • the object of the invention is a pliers of the applied pliers type, namely a To create water pump pliers whose locking can also be canceled by pressing a button is, but can be produced more cheaply and at least as well works well as plugged Knopffrastzangen the aforementioned type.
  • the new Pliers should be fast and secure directly on the workpiece and with always parallel jaws can be set so that an undesired adjustment is not possible.
  • Embodiments are The subject matter of claims 2 to 9; Claim 10 defines a feature combination.
  • each other at a variable distance opposite gripping jaws with particular have toothed mouth sections, wherein a first handle part a profiled slot and a second grip part a bearing bore for rotatably disposed therein Sliding joint has a slidable in the slot and lockable, two-sided flattened Slider has, according to claim 1 according to the invention provided that the slider in a central breakthrough a cylindrical foot of a locking bolt freely rotatable and axialverschietik leads and that a spring-loaded push button engages a shaft or head of the locking bolt to its latching repealed.
  • a Rastbolzenschaft enclosing supports Pressure spring on the one hand inside the push button and on the other hand at a Slider breakthrough axially limiting bridge.
  • This can be a support surface in form a blind hole of a stage body, which is a simple as well as space-saving and reliable construction. It is sufficient if the step body having a bottom with a central bore that guides the detent pin shaft, which end is connected to the push button.
  • the slip joint according to the invention consists of a total of at most five components: the slider, the detent pin, an insert, the compression spring and the push button, wherein compression spring and push button can also form a common component.
  • the small number of components allows a clear structure and very favorable usage properties.
  • the slider has a movable along a tool part Guide flange with a two-sided flattened step body, a centric Blind hole breakthrough and, on the narrow sides of a facing away from the flange Approach, having an external thread.
  • a simple component that takes up little space and at the same time reliably enables several functions. It is as a guide, in particular in a recess of predetermined shape, e.g. in a slot, an arched slot or the like., And also for stable support and as a fixation piece suitable.
  • the axially movable in the step body of the slider latching bolt has a Shank and a particular widened cylindrical foot, which is rotatable in the blind hole breakthrough of the slider sits.
  • This one has a robust component of simple form and correspondingly high structural strength.
  • the locking bolt shaft is preferably performed in a bolted to the slider insert, which is a Socket with remote internal thread may have, which screws with the approach.
  • the bush is attachable to the second tool part and has a collar offset internal thread on, with the approach of the slider stage body on Stop screwed.
  • the sleeve secures a predetermined distance and protects the internal parts it surrounds.
  • the first handle part is therefore a Einlochteil, which can have a closing stop and where the insert sleeve is preferably fixed with a collar.
  • the on stop tightened screw connection ensures the minimal movement of the game Pliers.
  • the slider has a step body with a flange on the slot part and a blind hole breakthrough, the locking bolt with its cylindrical, widened Foot leads.
  • Both pliers have full material thickness, i. There is no weakening, as is the case with conventional tongs. Such must to come from a fixed detent position in the sliding position, generally for Adjustment to be opened, which is not necessary according to the invention.
  • Other benefits of new pliers are the always parallel gripping jaws and the audible engagement of the Slip joint.
  • the water pump pliers Z shown as a whole in FIGS. 6 and 7 have two gripping parts A, B with mutually spaced apart gripping jaws G1, G2, which may in particular have toothed mouth sections.
  • a first handle part A has a profiled slot L and a second handle B a round hole R or a Bearing hole in which a the slot L enforcing slip joint 10 is rotatable is stored.
  • This consists, as shown in FIGS. 1a to 5b, of a maximum of five components, namely a slider 12, a locking pin 14, an insert sleeve 16, a compression spring 18 and a push button 20, wherein compression spring and push button can also form a common component.
  • the locking pin 14 ( Figures 4a, 4b) is axially displaceable in the slider 12 ( Figures 2a, 2b) guided by a cylindrical foot 15 of the locking bolt 14 in a centric Breakthrough 25 of the stepped slider 12 is arranged freely rotatable.
  • a shaft 24 of the locking bolt 14 is connected at the end to the push button 20. This is supported by the compression spring 18 at a breakthrough 25 axially delimiting Bridge 13 in the slider 12 from which forms the bottom of a blind hole 21.
  • the slider 12 has a guide flange 23 which can be moved along the slot part A. and a two-sided flattened step body 22 with an external thread 27 at a facing away from the flange 23 approach 26.
  • the step body 22 performs the axially movable locking pin 14, whose widened cylindrical foot 15 in the Shank 24 passes, which rotatably seated in a blind hole 21 of the step body 22.
  • the insert 16 (FIGS. 4 a, 4 b) is a bushing fixed to the round-hole leg B remote female thread 17, with the external thread 27 at the base 26 of the Step body 22 screws.
  • a central bore 30 in the bridge bottom 13 of the Blind hole 21 leads the locking pin shaft 24, the end with the push button 20th is connected, in which the compression spring 18 is supported, the counter-bearing on the ground the step body blind hole 21 has.
  • Fig. 1a shows the sliding joint 10 in the locked position.
  • the foot 15 of the locking bolt 14 locked the slider 12 on the slot leg A and with the shaft 24 of the Locking bolt 14 connected push button 20 protrudes over the top of the insert sleeve 16 addition, which is fixed to the round hole leg B to stop.
  • the slider 12 has a slot L on a tool leg A along movable flange in the form of the shoulder 19 and a two-sided flattened step body 22, the approach 26 at the shoulder facing away Side has an external thread 27.
  • the shaft 24 of the locking bolt 14 together with its widened cylindrical foot 15 guided axially movable, namely rotatable in the centric Bore 30 of the blind hole 21, the bottom 13 an abutment for the compression spring 18th forms, which has its other support surface in or on the push button 20.
  • the slide joint 10 is a very compact construction of a maximum of five components, which is on a two-piece Tool, e.g. a pair of pliers, is advantageously used to selectively a clutch in desired position or uncoupling to adjust cause.
