Definitions

  • the invention relates to tweezers, which are known per se Way has two legs, each on one their ends are connected and at their ends other ends by the action of a manual closing pressure brought together for temporary intervention can.
  • Tweezers of this type have been around for a long time and in many designs known, e.g. in DE GM 85 31 382, CH 376 064 and EP 0 849 048.
  • Such tweezers essentially exist from two legs, mostly made of steel, each at one end by welding, soldering or riveting are interconnected.
  • DE GM 295 12 216 is also a one-piece and from Steel (see material specification 1.4021 in the drawing) described, whose two legs by one Transition area connected to each other, which is the result material deformation by bending, and preferably still have a bent or milled spring, the manual one normally required for tweezers Closing resistance of at least about 50 g or the to ensure associated restoring force.
  • tweezers For many purposes it would be using tweezers desirable if such tweezers were made of light metal or simply and economically from light metal could be made.
  • the advantages of light metal tweezers lie on the one hand in the lower mass and on the other hand in that the possibilities for surface design of articles made of light metals, such as aluminum or magnesium or aluminum or magnesium alloys, due to the possible oxidation processes diverse and both in terms of color options as well as the surface properties (e.g. thanks to the Hardness of aluminum oxide) would be advantageous and without an additional spring offers sufficient closing force.
  • the tweezers according to the invention are characterized in that that they're out one of a light metal profile by cutting it across Element formed in the longitudinal direction of the profile exists and formed in one piece is. Accordingly, both the legs of the Tweezers as well as their connection from one single workpiece.
  • the connection preferably has that Shape of an apex area, each in the thigh transforms.
  • the apex area is preferably a material reinforcement or thickening.
  • thickening an increase in normal thickness in some areas the leg of the tweezers understood.
  • the legs Have thickenings to limit deformation.
  • Thickenings typically have a thickness that is at least around 20% larger than the normal thickness of the legs.
  • the "normal" thickness of the legs is the reference thickness in the overriding part of the legs between the Tweezers tip (working end) and the tweezers end (leg connection).
  • the legs of a pair of tweezers according to the invention can their ends at which they are engaged can be claw-like in a manner known per se and / or be tapered.
  • the thighs have usually one in the area between their ends prismatic and preferably approximately rectangular cross section, whose height corresponds to the normal thickness of the legs and whose width is at least twice greater than is the normal thickness.
  • a method is suitable in which one consisting of light metal Extruded profile with one of the tweezers to be produced corresponding cross-sectional shape at least approximately transversely is cut to the longitudinal direction of the profile, one Deviation of up to approximately 15 ° (corresponding to a cutting angle of up to about 75 ° or a deviation uim 1/6) normally still falls under this condition.
  • FIG. 1 shows the semi-schematically shown Side view of the tweezers 10 or the light metal profile, from which the tweezers are cut or Cutting the profile at least approximately perpendicular to the Profile longitudinal direction to form a sequence of profile pieces, preferably with at least approximately the same width has been manufactured.
  • the legs 12, 14 extend from their claw-like trained ends 121, 141 to the apex region 13, in which they merge into one another continuously.
  • the apex region 13 can be designed as a thickening be by its thickness at the cross section of the through the Vertex S extending longitudinal axis of the tweezers 10 at least is 20% thicker than the thickness in the apex area 13 merging legs 12, 14.
  • the embodiment is the one with the transfer number 130 marked inner surface I of the apex region 13 arcuate or curved semicircular; the shape of the outer surface can be chosen similarly or differently, as long as a sufficient thickness of the Vertex area 13 is guaranteed.
  • the legs 12, 14 can be close to the claw-like ends 121, 141 or in the vicinity of the apex region 13 Thickenings 171, 172 and 151, 152 can be provided to the Deformation of the tweezers 10 when too large limit manual closing pressures and thereby one to avoid permanent deformation.
  • the legs 22, 24 go in an apex region 23 in one piece over each other, the apex S in one acute angle, with the inner surface I or is approximately semicircular.
  • This however, is also a preferred and not a critical one Condition, since also an embodiment as shown in Fig. 3 tweezers according to the invention is possible in which the legs 32, 24 in one piece in an apex region 33 merge into one another, its apex S and its inner surface I each run at an acute angle to each other.
  • FIG. 4 43 shows a further example of a device according to the invention Tweezers, in which the apex 43 in one piece merging legs 42,44 at the transition to the inner surface I have depressions as used for adjustment the desired restoring force of an inventive Tweezers can be used.
  • the generally arcuate embodiment shown in FIG. 5 of the apex region 53 requires at the transition Leg 52,54 no thickening when extruded from a Light metal profile - i.e. not by bending - is manufactured.
  • Tweezers according to the invention do not require any additional i.e. separate spring elements, such as the curved steel tweezers the state of the art.
  • Suitable materials for the tweezers according to the invention are suitable.
  • Examples are commercially available Alloys mainly Al and / or Mg as well usually also Si and possibly other alloy components contain.
  • Such alloys are, for example light metal alloys corresponding to DIN 1748, such as under the type designations F11, F21, F28, F31 etc. are available, as well as those under the brand names Alloys available from Avional and Perunal.
  • Such light metal alloys are preferred for the purposes of oxidize on the surface with the usual methods let ("anodizing process"). Otherwise, the choice is yours suitable light metal alloys based on those described here Requirements in the area of professional knowledge.
