Definitions

• the invention relates to double scissors, in particular hair cutting scissors, with the features of the introductory part of claim 1.
• a combination hair cutting scissors in the form of double scissors is known from FR 2 601 279 A.
• This known pair of scissors has two scissors arranged at a distance from one another and parallel to one another, each with two cutting blades.
• One of the two scissors has cutting blades with substantially smooth cutting edges and the other scissors has cutting blades, at least one of which has a toothed cutting edge.
• the known double scissors have only one pair of finger rings.
• the invention is based on the object of improving the known double scissors and, in particular, of designing the setting of the scissors in the region of their joint between the cutting blades in such a way that the scissors are each independent of the other scissors on the optimum cutting action, ie the correct "pull" ", can be set.
• this object is achieved with a pair of double scissors with the features of claim 1.
• each of the scissors of the double scissors according to the invention can be adjusted independently of the other scissors so that it has the optimum "pull", that is to say cuts particularly well .

• FIG. 12 an inventive double scissor from the side of the scissors with smooth cutting blades 13
• FIG. 13 the scissors of FIG. 12 seen from the side of the scissors with toothed cutting blades.
• the double scissors according to the invention in particular designed as hair cutting scissors, in the exemplary embodiment shown consist of two scissors 1 and 2.
• the scissors 1 has two toothed cutting blades 3 and 4 which are pivotally connected to one another in the region of the axis 5 by a screw 6.
• the scissors 1 can also have a smooth and a toothed or serrated cutting blade, as indicated in FIG. 3.
• the legs 7 of the scissors 1 are angled at their ends 8 towards the other scissors 2 and are fork-shaped at the free end 9.
• the second pair of scissors 2 has 2 smooth cutting blades 10 and 11 which are connected to one another in a pivotable manner in the region of the axis 5 by means of a screw 12.
• the legs 13 of the scissors 2 have flattened areas 15 in the region of the finger rings 14, over which the fork-shaped end 9 of the legs 7 of the other scissors 1 engages, so that when the scissors 2 are actuated, the scissors 1 are also actuated via the finger rings 14.
• the seat of the fork-shaped ends 9 on the legs 13 is loose, so that the ends 9 are movable relative to the legs 13 of the scissors 2 are led.
• the cutting blades 3 and 4 of the scissors 1 without finger rings are bent towards the scissors 2 in the region 28, the angle of the kink being only a few degrees, for example 1 °.
• the extent of the kink can be of different sizes for the cutting blades 3, 4 of the scissors 1.
• 10 and 11 show the connecting screws 6 and 12 of the scissors 1 and 2 which serve as joints between the cutting blades 3, 4 and 10, 11 of the scissors 1 and 2.
• the connecting screw 6 exclusively connects the cutting blades 3 and 4 of the scissors 1 and the connecting screw 12 only connect the cutting blades 10 and 11 of the scissors 2 to one another.
• the cutting blades 3 and 4 of the scissors 1, on the one hand, and the cutting blades 10 and 11 of the scissors 2, on the other hand can be adjusted independently of one another for optimum cutting action (“pull”) by actuating the connecting screws 6 and 12 assigned to them.
• 10 and 11 also show that in one of the two screws 6 and 12 - in the embodiment shown in the connecting screw 12 - a hinge pin 20 is inserted, which engages in a hole 21 in the other screw 6, as shown in Fig. 11b and 11c.
• the scissors 1 and 2 are connected to one another in the region 30 of their legs 7 and 13.
• the connection of the legs 7 and 13 is designed such that the distance of the legs 7 and 13 from each other and thus the orientation of the two scissors 1 and 2 in the area of their cutting blades 3 and 4 or 10 and 11 to each other to the optimum value, that is optimal cutting effect can be set.
• the position of the scissors 1 and 2 relative to one another, ie the angle that they are with one another include, be adjusted.
• the two scissors 1 and 2 pivot about the area of the coupling of their legs 7 and 13 in the area of the fork-shaped ends 9 and the flattened area 15 to one another. It is preferred that only one of the legs 7 of the scissors 1 is firmly connected in the region 30 to the associated leg 13 of the scissors 2. Usually this will be the right leg 7 in FIG. 13. The other leg 7 lies over its projection
• FIGS. 8 and 9 An example of such a connection is shown in FIGS. 8 and 9.
• the legs 7 of the scissors 1 and the legs 13 of the scissors 2 have projections 31 to be directed towards one another in the region 30.
• Bores 32, 33 are provided in the area of the projections 31.
• the bore 32 is designed as a threaded bore, whereas the bore 33 is designed as a stepped bore, the further region of which is the head 34 of a connecting screw 35 which is inserted into the threaded bore
• the head 34 becomes the
• An elastic ring 38 can be inserted between the head 34 of the connecting screw 35 and the bottom or the shoulder of the stepped hole 33. Additionally or alternatively, an elastic disk 39 or an elastic ring 38 can be inserted between the mutually facing surfaces of the projections 31.
• the elastic rings or disks 38 and 39 ensure an intentional adjustment of the distance between the legs 7 and 13 and thus the alignment of the two scissors 1 and 2 in the area of their cutting blades 3, 4 and 10, 11 to one another.
• Figures 10 and 11 show a practical embodiment of a pair of scissors according to the invention seen from different sides.
• the double scissors according to the invention have different advantages thanks to their different scissors 1 and 2.
• the toothed cutting channels provided, for example ten can have a 3 to 9 mm large, essentially smooth cutting edges on each tip. These cutting edges make it possible to intensely fringe the tips of the hair when cutting over the fingers.
• the distance between the scissors 1 and the scissors 2 is preferably about 4 to 5 mm in the area of the cutting blades. Depending on the desired cutting result effect, the distance can also be smaller or larger.
• the distance between the teeth or teeth of the cutting blades 3, 4 of the scissors 1, as well as their width, can have a different size than that shown in the drawings.
• a double scissors has two interconnected, differently designed cutting blades 3, 4, -10, 11 having scissors 1 and 2.
• the connecting screws 6 and 12 of the two scissors 1 and 2, which the cutting blades 3, 4 and 10, 11 of the scissors 1 and 2 each with an articulated connection, can be set independently of one another.
• the scissors 1 and 2 are connected to one another in the region of the pivot axis 5, about which the cutting blades 3, 4 and 10, 11 are pivotable relative to one another, by means of a hinge pin 20.
• Only one pair of scissors 2 of the two scissors 1 and 2 has finger rings 14.
• the other pair of scissors 1 has legs 7, the ends 9 of which are bent in a fork shape.
• the forks 9 encompass the legs 13 of the other scissors 2 having finger rings 14, so that the scissors 1 are also actuated synchronously and to the same extent by actuating the scissors 2 via the finger rings 14.
• the legs 7 and 13 of the two scissors 1 and 2 are additionally connected to one another in the region 30 between the finger rings 14 and the pivot axis 5 by adjustable connecting means 35.
• These connecting means which connect the two legs 7 and 13 of the scissors 1 and 2 to one another, can be adjustable and fixable screws 35.
