Definitions

  • the present invention relates to a gripper with the Features of the preamble of claim 1.
  • Gripping pliers of this type are known from practice. At a Known pliers cross the handle and the Pliers bracket in a joint that has an elongated locking hole includes. A pin that forms the bearing axis of the joint is star-shaped or round in cross section and engages positively in the longitudinal direction of the slot Rest hole. The peg is in its locked position from biased an unprotected leaf spring, the on the outside of the Joint. To adjust the mouth width of the known Gripping pliers is the pin against the force of the leaf spring push in the pliers joint so that its larger Cross section is pushed out of the locking hole. Then can the pliers bracket against the pliers handle to the desired extent be adjusted. As soon as the pin is released, press the leaf spring puts it in the engagement position with the locking hole, and the intended jaw width of the gripping pliers is fixed.
  • This task is performed by a gripper with the characteristics of Claim 1 solved.
  • the joint with its the adjusting element in a particularly compact manner be built.
  • a more compact design enables one Construction with little possibility of attack from the outside.
  • Setting element an essentially rotationally symmetrical Includes locking pin.
  • This locking pin can, for example, as simple turned part with great precision inexpensive getting produced.
  • the round or cylinder-like Offers the outer contour of the rotationally symmetrical turned part also good resistance to external Damages and the easy way to do this Clean the component if it is dirty.
  • This arrangement also enables a stop for the locking pin and thus a limitation of the path along which the locking pin is displaceable. So there is one defined end position of the locking pin in the Adjustment position.
  • An advantageous embodiment also results if the Locking pin in the engaged position also the bearing axis of the joint.
  • the double function of the locking pin as Adjustment element and bearing axis reduce the number of required components.
  • An easy way to The configuration of the setting device results when the Locking pin a first area of larger diameter and has a second area of smaller diameter.
  • the forceps handle or the forceps bracket is an elongated one Have locking hole in which the locking pin with its first Area rotatable immovable and with its second Area slidably engages in the longitudinal direction.
  • a such a structure ensures a particularly simple and thus reliable construction.
  • the outer area of the Forceps joint if the forceps handle and / or the forceps bracket a space at least partially in the area of the joint limit in which the locking pin against the bias of the Spring can be pressed. If moreover the coil spring with its end remote from the locking pin Cover plate is assigned as an abutment, so the room broadly closes that protection against pollution, Damage and / or loss of the coil spring results, so will the reliability and durability of the present gripping pliers further improved.
  • An advantageous one Embodiment of the present invention can also provide that a snap spring is assigned to the locking pin, which serves to pretension the locking pin and / or the space closes to the outside. With this arrangement the The adjustment device is sealed to the outside, while the snap spring resilient over a dead center at the same time takes over the pretensioning of the locking pin. This Arrangement saves against the bias by means of Coil spring another component.
  • the Gripping pliers comprises a pliers handle 1 and a pliers bracket 2, each provided with a handle section 3 or 4 are.
  • the pliers handle 1 and the pliers bracket 2 intersect in a joint 5, which has a locking pin 6 and an elongated Latch hole 7 includes.
  • On the handle sections 3 and 4 opposite side of the joint 5 have the forceps handle 1 and the pliers 2 each have a gripper jaw 9 or 10, the together form a pliers mouth.
  • the pliers handle 1 is in the region of the joint 5 with a the representation according to Figure 1 parallel to the plane of the drawing provided running slot through which the pliers bracket 2 is inserted so that the pliers handle 1 Pliers clamp 2 engages on both sides in the area of the joint.
  • FIG. 2 shows the gripping pliers according to FIG. 1 from the opposite side.
  • the same components are the same Provide reference numbers.
  • In the area of the joint 5 is in Figure 2 not visible locking pin 6 from a cover plate 11th covered.
  • the pliers joint 5 is in a cross section shown approximately along the line III-III of Figure 2.
  • slotted handle 1 has one left area 1a and a right area 1b, which in of Figure 1 and Figure 2 can be seen.
  • the clamp 2 is between the left side 1a and the right side 1b of the Plier handle 1 introduced.
  • the locking hole 7 is, as in the Figures 1 and 2 shown, elongated formed from a Series of several cylindrical bores, the partially overlap. The center of the holes are less than one bore diameter apart offset, so that between the respective holes there is a free passage, but it is wide is limited.
  • the locking pin 6 is as executed rotationally symmetrical rotating part and has one outer, dome-shaped pressure region 15, which of the Pliers joint 5 points outwards.
  • a concentric blind bore 20 is from the front introduced larger diameter in the locking pin 6 and ends shortly before the pressure range 15.
  • the blind bore 20 is provided for receiving a coil spring 21, the has a total of about the length of the locking pin 6.
  • the Coil spring 21 is in the installed position at about two Thirds of its length guided laterally in the blind bore 20, what a great security against an accidental Kinking results. As the locking pin 6 opposite Abutment for the coil spring 21 acts on the cover plate 11.
  • Figure 3 shows the pliers joint 5 and in particular the Locking pin 6 in its engaged position in which the area 18 larger diameter in the cylindrical bores of the Locking hole 7 engages.
  • the joint is 5 in Longitudinal direction of the locking hole 7 immovable, the Locking pin 6 bearing axis and pivot axis of the pincer joint 5 forms.
  • the user of the gripping tongs press on the pressure area 15 of the locking pin 6 and this towards the cover plate 11 against the force of Shift coil spring 21.
  • the Plier handle to be moved relative to the clamp because the area 16 of smaller diameter also through the narrowed areas of the locking hole 7 fits through.
  • the locking pin 6 be released and will return from the coil spring 21 pushed into the rest position. This position will taken as soon as a bore area of the locking hole 7 for Coverage comes with the area 18 of larger diameter, whereby snapping into place between areas 16 and 18 attached chamfer is facilitated.
  • the present invention is a clickable adjustable Gripping pliers, which consists of only five components.
