Definitions

  • the invention relates to a pair of pliers, the handle legs of which are connected to one another via a joint and each form a jaw in the working area and are designed to be gripped in the area of their opposite free ends.
  • Such pliers are used for pulling nails, pens or the like. as well as for cutting metal objects, e.g. Wires, used.
  • a corresponding clamping force For the function of pulling, a corresponding clamping force must first be introduced via the two handle legs. The actual pulling process is then carried out by applying force perpendicular to the handle legs, which can take place in the direction of the rounded gripping jaws by a rolling process or perpendicularly to this by tilting the jaws on the drawing base. Often, rolling movements are also encountered in a plane on both sides away from the longitudinal axis of the object to be drawn within a pulling process. The required forces are then directed either against the wrist and middle of the finger or against the middle hand and end of the finger. With conventional Biting pliers apply both the clamping forces and the forces in connection with the pulling of grip legs which are rectangular or approximately rectangular in grip cross section and which are generally too small in size. Extreme pressure peaks in the palm and fingers are the result.
  • pulling operations also occur parallel to the longitudinal axis of the pliers if, due to space restrictions or concern about the sensitive surface, no support options are possible on the drawing base.
  • the invention has for its object to design a pair of pliers in such a way that its handling for the user is improved and thus more pleasant. In particular, the strain on the hand should be reduced.
  • the grip legs have a grip area in the region of their free end, in which they have approximately the shape of an ellipse or an oval when viewed on the broad side, and also have the shape of a shape when viewed in the narrow side view Have an ellipse or an oval, the outer contour of a cross section through both legs being part of an ellipse or an oval.
  • the advantage of the invention is that the novel design of the hand side of the pliers, the two handle legs are adapted to the anatomy and anthropometry of the human hand.
  • the starting point here is that the pliers are operated by hand gripping.
  • a natural curvature through the hand skeleton is provided both on the wrist and in the area of the finger joint. This is taken into account by appropriate shaping of the handle legs.
  • the two handle legs represent the pointed ends of an ellipse.
  • the side flanks of the handle legs are also curved so that when the force is applied, they also correspond to the natural curvature of the palm, transverse to the closing movement.
  • there is a favorable contact surface for the hand closure for all activities that occur with the pliers e.g. Clamping, levering perpendicular to the pliers axis and pulling along the pliers axis.
  • the grip area is clearly separated from the rest of the grip leg. This can be done, for example, by changing the width, or also by changing the thickness or, if appropriate, also by changing the arrangement of the grip legs. Combinations are also possible. This clear separation between the grip area and the rest of the area enables the user to automatically get into the grip area with his hand without looking.
  • the grip area is separated from the rest of the grip leg by an indentation in the outer contour of the grip leg. The user automatically slides into the grip area with his hand.
  • the leg distance in the area of the free end of the handle area is smaller than in the area of the opposite end of the handle area.
  • the grip legs are offset parallel to one another at least in the grip area.
  • the direction of the displacement is chosen such that the handle leg assigned to the four fingers is offset from the palm. This takes into account the fact that when the hand is closed, the finger limbs do not move directly in the direction of the counter bearing formed by the area of the carpal root.
  • the width of the legs in the handle area is greater than in the rest of the handle legs. This also results in a clear separation of the grip area from the remaining area of the pliers.
  • the pliers shown in Fig. 1 consists of two handle legs 11, 12 which are connected to each other via a joint 13. Due to the connection with the joint 13, the two legs 11, 12 can be pivoted about the axis formed by the joint 13. On one side, the upper side in FIG. 1, of the joint 13, the grip arms 11, 12 each form a jaw 14, 15. On the opposite side of the joint 13, the grip arms 11, 12 have a grip area 17, which differs from the free end 16 of the handle legs 11, 12 extends for about a hand width and is separated from the rest of the handle legs 11, 12 by an indentation 18.
  • the opposing grip legs 11, 12 are designed such that their outer sides follow approximately the shape of an ellipse or an oval in the broadside view shown, which is indicated by the dash-dotted line 19.
  • the large axis of the ellipse or oval 19 extends in the longitudinal direction of the handle legs and is approximately 100 mm, while the axis perpendicular to it is approximately 50 mm.
  • the distance between the outer sides of the handle legs 11, 12 at the free The end 16 of the grip area 17 is slightly smaller than the distance between the outer sides of the grip legs 11, 12 in the area of the opposite end of the grip area 17.
  • the outer periphery of the handle legs 11, 12 in the grip area 17 has approximately the shape of an elongated ellipse, the major axis of which is also approximately 100 mm , whose small axis has an amount of about 25 mm.
  • Fig. 3 now shows a cross section approximately along line III-III in Fig. 1, i.e. approximately at the level of the small axis of the ellipse indicated by line 19.
  • the outer surface 20 of the handle leg 11 and the outer surface 21 of the handle leg 12 are both in an ellipse 22 and 23, respectively, both ellipses being of the same design but being laterally displaced so that their major axes remain parallel to one another.
  • the outer surfaces 20, 21 of the handle legs 11, 12 each lie in the area of the apex of the ellipse.
  • the large axis of the ellipse 22 or 23 runs from the outside 20 of one grip leg 11 towards the outside 21 of the other grip leg 12, which is not intended to be offset.
  • the large axis 24 and the small axis 25 of the ellipse are shown in the narrow side view of the grip area 17.
  • the dimensions are identical to the embodiment according to FIG. 2, the only difference from the embodiment according to FIGS. 1 to 3 is that the handle legs 11, 12 are not laterally offset in their handle area 17. 5, the two ellipses 22, 23 also coincide.
  • the handling for the user of a pair of pliers with two handle legs and one jaw each, which are operatively connected via a joint, is optimized and improved by an ergonomic design of the handle legs.
  • the advantage of this design of the hand side of the pliers is that the handle legs are optimally adapted to the anatomy and anthropometry of the human hand for all applications.
