  • Patent number: 6427338
    Abstract: Pair of scissors, in particular hair-cutting scissors, consisting of two scissor halves (1, 2), each comprising a scissor blade and a tang (3) with a grip eye (4, 5, 6, 7), where the grip eye (4, 5, 6, 7) of at least one scissor half (2) is mounted such that it can slide essentially parallel to the tang (3) and be locked in position. The inventive activity consists in the fact that the sliding grip eye (4, 5, 6, 7) is integrally molded on a first handle section (8), and a second handle section (9)is mounted on the tang (3), where the first handle sect-ion (8) can be slid onto the free end of the second handle section (9) and, in this position, can be snapped onto the second handle section (9) in releasable fashion without any adjusting elements, and where the two handle sections (8, 9) form a uniformly closed handle with smooth transitions without disturbing adjusting elements.

  • Patent number: 6408523
    Abstract: A pair of scissors, in particular haircutting scissors, has a hinged joint consisting of a hinge screw (3) and a screw nut (4). The hinge screw (3) is essentially non-rotatably connected to one scissors half (2) and the screw nut (4) engages in a bore (12) in this scissors half (2). Situated in said bore (12) is a first flexible body (15) which, under contact pressure, sits against the end of the screw nut (4) facing the head (5) of the hinge screw (3) and against the shaft (9) of the hinge screw (3). To ensure that even a short screw nut will be securely held and can be precisely adjusted, the invention provides that the screw nut (4) has on its outer circumference a groove (18) in which is situated a second flexible body (19) which, under contact pressure, sits against the screw nut (4) and the bore (12) in the scissors half (2).

  • Patent number: 5987757
    Abstract: In scissors, especially haircutting scissors, with two handles (1, 2) and handle eyes (4) arranged at the ends of the handles, where at least one of the handle eyes (4) is provided with a movable grip eye (5) which accommodates the thumb or a finger of the person using the scissors, in order to guide the scissors with movable grip eye (5) precisely and to reliably position the grip eye (5) in the handle eye (4), it is envisaged that the grip eye (5) is enclosed by the corresponding handle eye (4) along the entire circumference and displays guide elements projecting radially outwards on both sides, which lie laterally against the handle eye (4), meaning that the grip eye (5) can rotate freely about the axis perpendicular to the handle eye (4), while being mounted in the handle eye (4) in such a way as to be incapable of rotation perpendicular to this axis.

  • Patent number: 5722171
    Abstract: In scissors, particularly hairdresser's scissors, with two scissor blades (1, 2), connected to each other in articulated fashion by means of a single pivot (3), and two scissor handles (4, 5), each of which displays two handle sections (28, 29) and (30, 31), where the first handle section (28, 30) is connected to its corresponding scissor blade (1, 2) and the second handle section (29, 31) includes the end grip of the scissor handle (4 or 5), and where the two corresponding handle sections are connected to each other in articulated fashion to permit pivoting in the plane of the handle, it is envisaged that the two handle sections can be locked in various angular positions in relation to each other in order to allow optimum ergonomic setting, and that locking takes place in the articulated connection of the handle sections.
