Definitions

  • the invention relates to tweezers, in particular one Cosmetic tweezers, with two in the longitudinal direction Tweezer thighs through a common joint are interconnected.
  • Tweezers for different applications e.g. in the Cosmetics, medicine or surgery or technology or Electronics are known in many different forms.
  • Cosmetics in particular have two types of tweezers Spread, namely the so-called pointed tweezers and the so-called jaw or slanted jaw tweezers, also called "slant" tweezers.
  • the point of the tweezers is the functional end, i.e. the end that when actuating the tweezers for grasping of an object is closed, typically one uniformly converging tip.
  • tweezers with one at the functional end Gripping edge provided jaw which, when actuated, i.e. closing the tweezers, e.g. by squeezing or pivoting of the legs, one increasingly form a closing gap; between the inner surfaces of the Baking creates a flat surface when the tweezers are closed Contact, i.e. a common gripping surface.
  • the gripping edges run obliquely to the longitudinal axis the tweezers, typically at an angle of about 60 °.
  • a general advantage of pointed tweezers is their practicality punctiformly defined functional end and one accordingly precise function control; the general Disadvantage is that the pointed functional end can be permanently deformed at higher closing pressures and the two ends of the thighs that are functional Form the end of the tweezers, then diverge permanently, i.e. the tweezers no longer "grips".
  • Cheek tweezers are subject to this disadvantage of pointed tweezers not or to a significantly reduced extent; the Gripping surface at the functional end can be a pinched in between Hold hair securely, and also a strong one Closing pressure does not normally lead to a permanent, but at most an elastic resetting Deformation of the functional tweezers end.
  • DE G 85 31 382 is a pair of tweezers according to the preamble of claim 1 with a tip and a substantially triangular gripping piece known, wherein the two sides starting from the tip of the tweezers of the triangular gripping piece with the tweezers axis include different angles.
  • Such tweezers represents a combination of pointed tweezers with angled jaw tweezers, but has the disadvantage that the closing force of the diagonal jaws is often not always sufficient to hold an object gripped with the slanted jaws to hold sufficiently tight.
  • the object of the invention is a pair of tweezers just described Way to offer the benefits of pointed tweezers combined with the advantages of jaw tweezers and has an improved gripping effect.
  • Tweezers have the features of claims 2 - 10th
  • the tweezers 1 shown in Fig. 1A-C has in usually two metallic tweezers legs 11, 12, which are mostly made from ribbon-shaped semi-finished products are firmly connected to one another in the connecting region 18, e.g. by pressure welding.
  • each leg 11, 12 is provided with a jaw 110, 120, and each of these jaws has an elongated edge 111, 121 and a pointed end 112,122.
  • the jaws 110, 120 can pass through the recesses 171, 172 should be offset to the tweezers 1 to give an overall slim shape.
  • the one broken functional circle indicated functional End 16 is closer below in connection with FIG. 3 explained.
  • the tweezers 2 shown in FIGS. 2A and B is one scissor-type jaw tweezers, both of which Leg 21,22 by a common link 281, for example a screw or rivet, like scissors are movably connected.
  • a common link 281 for example a screw or rivet, like scissors are movably connected.
  • Fig. 2B At the functional end 26 (Fig. 2B) of the tweezers 2, which in turn by a open-drawn circle highlighted and related is explained in more detail with Fig. 3, everyone wears Leg 21,22 a cheek 210,220, which is similar to the Bakken 110, 120 of the tweezers 1 shown in FIG. 1 are.
  • the functional end 26 of the tweezers 2 opposite actuation end 29 (Fig.
  • the legs 22, 21 of the tweezers 2 are in accordance with a preferred embodiment from semi-finished with approximately semicircular cross section.
  • the degree of wedging or convergence adequate mechanical reinforcement of the Gripping edges provides a significant permanent set to avoid baking even with increased closing pressure.
  • Fig. 4 the degree of wedging or convergence the approximately wedge-shaped entire end face 40, that of the two merged partial end faces 401,401 the tweezer leg 41,42 is formed characterized by the ratio (H: B) according to the invention must not be larger than about 4.
  • H is there the "height" of the end face 40 and B is the "width” or "Length” of this base, which - apart from that preferably existing converging gap 44 - generally approximate is determined by the thickness of the tweezer legs.
  • the inner surfaces of the tweezers legs can be at maximum Closing pressure lie against each other or in this Form a gap between each other, e.g. in the Case of the scissors tweezers of Fig. 2 or a pair of tweezers type shown in Fig. 1 (not in the drawing protruding jaws.
  • the ratio H: B of at most 4 means one relatively strong convergence of the wedge with increasing ratio H: B decreases and with falling Ratio increases.
  • the value of H: B is preferably in the range of 1-4, more preferably in the range of 2-4; if convergence or wedge is too low, wedge-shaped end face 30.40, i.e. an H: B value of over 4, there is a risk of permanent deformation the functional end of the tweezers at higher ones Schliessteil. If the ratio is less than 1, then leads this usually results in an excessively heavy or chunky Tweezers form.
  • a pair of tweezers according to the invention Representation of Figures 3 and 4 designed functional End with approximately wedge-shaped end face and the specified Minimum convergence value allows that one ever according to the angle of attack of the tweezers 1,2 to one (in the drawings surface (not shown) on which a structure to be gripped with tweezers, in each case the functions and advantages of an inclined jaw or one Pointed tweezers can use without their disadvantages.
  • the tweezers 1, 2 act like one Angular Back tweezers; are the legs 11, 12; Approximately 21.22 perpendicular to the surface, this is how the tweezers 1,2 work like a pair of pointed tweezers, but with increasing closing pressure is not permanently deformed to a significant degree.
  • Angle ⁇ is generally less than 90 ° and is preferably at most 45 °; according to one particularly preferred embodiment is ⁇ approximately 30 °.
  • the functional end 16, 26 of a pair of tweezers according to the invention is also shown by the ratio as shown in Fig.5 (SL: D).
  • SL is the "length" or Height "of the convergence area at the functional tip end 55 of the tweezers; D is the total thickness of the legs 51.52.
  • the ratio (SL: D) is at most is 5 and is preferably in the range 1-5; an SL: D ratio of about 4 is preferred for many purposes.
  • Stainless steel tweezers according to the invention are at least in the area of the cheek outer surfaces and in the whole Cheek area by machining, in particular by grinding.
  • a shape of the Bakken pressing is less preferred because one is sufficient precise shape when using sufficient hard steel, as is common for forging tools, then is comparatively difficult to achieve.
