Definitions

  • the invention relates to scissors, in particular hairdressing scissors, with one of a hinge screw and one Nut existing joint, the Articulated screw with a pair of scissors essentially non-rotatable is connected and the nut into one in this scissor half arranged hole engages in the a first flexible body is arranged, which is under pressure on the end facing the head of the joint screw the nut and the shaft of the hinge screw is present.
  • Such scissors are known from EP 0515830 A1, Fig. 6.
  • This pair of scissors is made of steel or another Existing nut of the joint an inner groove on its inner wall, in which a second ring-shaped one made of flexible material Body is arranged whose inner diameter is smaller than is the thread diameter of the hinge screw. Due to the Combination of the in the hole for the nut used first flexible body and the on the Inner wall of the nut arranged second flexible body, both under pressure on the shaft of the Joint screw, there will be a game between the Articulated screw and the screw nut Half of the scissors, the upper scissors, from the following Avoided reasons.
  • the hinge screw by two opposite milled surfaces and a correspondingly designed opening in Oberbeck connected to it essentially non-rotatably is, such can be done in mass production Shear some play of the hinge screw in the Opening in Oberbeck not entirely due to manufacturing reasons avoid.
  • This movement game takes place in today's Precision scissors with a very low closing pressure during the operation of the scissors by small strokes noticeable by the person operating the scissors to The hairdresser, for example, feels uncomfortable.
  • the hinge screw is also subject to impact a higher wear.
  • the present invention is therefore based on the object based on a pair of scissors of the type mentioned above to develop that even with shorter nuts secure hold and exact adjustability of the same in Oberbeck the scissors while preserving the benefits of the EP-0515830 A1 known scissors are guaranteed.
  • a pair of scissors of the type mentioned the nut has a groove on its outer circumference in which a second flexible body is arranged, which is under pressure on the nut and the hole in the Half of the scissors.
  • the invention makes a frictional connection between the hinge screw and the upper scissors Use that not according to EP 0515830 A1 above the first flexible body to Oberbeck and over the second flexible body runs to the nut, but the over the first flexible body and over the nut and the second flexible body to the Oberbeck runs. Surprisingly, it turned out that it is sufficient to solve the problem that the first flexible body under pressure on the shaft of the joint screw is present.
  • the desired adhesion between the Screw shaft and the Oberbeck as well as the desired good Thread fit of the nut even with a short nut and the sensitive adjustability to regulate the Closing pressure is achieved in that the full length the nut is used for the thread to the nut on the one hand through the first flexible body and on the other hand, by the second flexible body to be arranged in Oberbeck.
  • the invention particularly permits a screw nut, the completely or almost completely within the Oberbeck can be arranged and the head of the Hinge screw pioneering end face essentially aligned with the top of the relevant scissor half is arranged.
  • Such a pair of scissors Advantage that not, as usually on a protruding screw that can entangle hair, and that the hairdresser thereby easily over the comb can cut.
  • DE 81 37 176 U1 shows a screw nut one arranged in a circumferential annular groove flexible body that is under pressure on the Nut and the hole in the scissors half is present.
  • the groove arranged on the outer circumference of the nut as Ring groove and the second flexible body stored therein as O-ring formed.
  • the inner diameter same smaller than the thread diameter of the Joint screw may be provided.
  • the cross-section of the constriction can be essentially non-rotatable Storage of the hinge screw essentially that Cross section of the shaft of the hinge screw correspond.
  • the first flexible body is preferably as Molded part, the spatial dimensions of which Correspond to the geometry of the constriction.
  • the two are Scissor halves 1 and 2 of the scissors under consideration by one Joint screw 3 and a nut 4 with each other connected.
  • the head of the joint screw 3 is on the back on the circumference designed dome-shaped and is in one with this part enlarged end area 6 of hole 7 in the Unterbeck mentioned scissor half 1. In this extended end area 6 is the head 5 through a plastic slide ring 8 stored.
  • the shaft 9 of the joint screw 3 has two parallel ones lateral flats 10 on. While the shaft 9 in the Bore 7 of the lower basin 1 is arranged with play he reaches through an opening 11 in the Oberbeck mentioned Half of the scissors 2, with the flattened portions 10 of the shaft 9 has corresponding flats, so that the hinge screw 3 with the Oberbeck 2 essentially non-rotatably connected is.
  • a first flexible one is in the bore 12 of the upper basin 1 Body 15 arranged by an excess under pressure on the bore wall of the head 5 of the hinge screw 3 facing end face of the nut 4 and the shaft 9 the joint screw 3 rests.
  • the first flexible body 15 is designed as a molded part, as it is more precisely from the Figures 6 and 7 emerges.
  • the ring-shaped Molded part is conical on one end with which it on a likewise conically shaped transition surface 16 between the opening 11 and the bore 12 in the Oberbeck is present.
  • the opening 17 in the body 15 corresponds in its Geometry of opening 11 in Oberbeck 2 or shaft 9 the hinge screw 3, but the internal dimensions less than those of the opening 11 or the shaft 9 the hinge screw 3 are.
  • the flexible body 15 is as rubber-like, highly elastic molded plastic part manufactured.
  • the screw nut 4 on its outer Includes a groove 18 in which a second flexible body 19 is arranged, the pressure under pressure on the Screw nut 4 and the bore 12 in Oberbeck 2 is present.
  • the groove 18 is an annular groove and the second stored therein flexible body 19 formed as an O-ring.
