Description

Scissors, especially barber scissors or craft scissors

The invention relates to a pair of scissors, in particular barber scissors for cutting human hair or animal hair or craft scissors for cutting paper, cardboard or textile fabrics, with a first scissor blade and a second scissor blade, wherein the first scissor blade is designed as a double cutting blade.

Conventional scissors, in particular scissors for cutting human hair or animal hair or craft scissors for cutting paper, cardboard or textile materials are known from the prior art, which have in the usual way two mutually movable and thereby cooperating scissor blades, each with a cutting edge, wherein in each case a scissor blade is part of a Beck also called scissor leg and the two Becks each have a handle on which a handle eye is formed. Scissors for cutting human hair or animal hair are hereafter referred to as barber scissors.

In particular, hairdressers work with different types of scissors, namely with a hairdressing scissors hereinafter referred to as hairdressing scissors for "normal" cutting hair, which includes two smooth cutting and often

Slice scissors is called. In addition, for thinning hair, the use of a hairdressing scissors hereinafter referred to as Thinning scissors with two toothed cutting with appropriate teeth and a so-called

Modeling scissors, which includes a smooth cutting edge and a toothed cutting edge with suitable teeth, possible. When using the scissors as thinning scissors, the hair is thinned slightly. The two-sided toothing causes the thinning scissors namely that only about a third of the hair per strand of hair are detected and cut. When using the scissors as a modeling scissors, the hair is thinned on the other hand reinforced. The one - sided toothing leads to the

Modeling scissors that about half of the hair per strand of hair are detected and cut. Depending on the design of the teeth and less hair can be detected, especially between about one third and half of the hair of a strand of hair.

From the German utility model DE 77 33 515 is a multifunctional Hairdressing scissors are known which are equipped with three different scissor blades. Here, a first, outer scissor blade has a common, smooth cutting edge. The smooth cutting edge faces a middle, second blade. The second, middle scissor blade is designed as a double cutting blade, which has a smooth edge which is adjacent to the first scissor blade and the smooth blade

opposite is equipped with a toothed cutting edge. A third, outer scissor blade is at its inner, i. the middle double cutting blade

facing cutting edge provided with thinning teeth that correspond to the teeth of the double cutting blade. Depending on the position of the three cutting blades to each other - the middle scissor blade can be brought into engagement with one of the outer scissor blades via a pawl - the scissors as

Hairdressing scissors or thinning scissors are used. The three different scissor blades thus combine the function of cutting and thinning in a single pair of scissors.

The German utility model DE 85 17 639 discloses a so-called

Thinning scissors, so a barber scissors for thinning the hair. The scissors include a first scissor blade with a serrated edge and a second scissor blade with a smooth edge. The second scissor blade also has teeth generated thereon, the individual teeth of which have different lengths and protrude from the smooth blade of the scissor blade. With such a pair of scissors, the steps resulting from thinning no longer occur in the finished hairstyle

Appearance. Advantageously, the toothing can be produced on a body made for itself, which is designed as a slide and can be brought via a arranged on the second scissor blade guide with this in detachable connection.

From the patent application DE 10 201 1 016 134 A1 a pair of scissors with a double cutting blade is known, which should be equally suitable for left and right-handed persons.

DE 299 1 1 467 U1 discloses a pair of scissors with an enlarged range of application.

The invention has for its object to provide an improved multifunctional scissors, especially barber scissors or craft scissors, ready. This object is achieved by a pair of scissors with the features of claim 1. In the dependent claims 2 to 9 10 and the following description of advantageous embodiments of the invention are given.

A pair of scissors, in particular barber scissors for cutting human hair or animal hair or craft scissors for cutting paper, cardboard or textile fabrics, with a first scissor blade and a second scissor blade, wherein the first scissor blade is designed as a double cutting blade is inventively improved by an orientation of the first scissor blade is thus detectable in a first position or a second position different from the first position, that in the first position, a first cutting edge of the first

Scissor blade cooperates with the second scissor blade and in the second position a second blade of the first scissor blade cooperates with the second scissor blade.

In the context of this invention, a double cutting blade is to be understood as a scissor blade which comprises two functional cutting edges. In this case, the cutting edges are usually formed on one and the same and thus one-piece scissor blade. The cutting edge can in this case a smooth, in particular continuous smooth,

Cutting edge without teeth or a toothed cutting edge have. This not only applies to double cutting blades, but also to simple scissor blades with only one cutting edge. The smooth cutting edge and the toothed cutting edge, the latter especially in the area of the teeth, can be sharpened by means of a special cut, both in simple scissor blades and in double cutting blades. By interaction of two corresponding cutting can then cut with hairdressing scissors, for example, hair or thinned and with

Craft scissors, for example, paper, cardboard or textile fabrics with straight or odd, in particular jagged, cut lines or cut geometries are cut. In known from the prior art

Double cutting blades, the cutting are usually arranged opposite each other, so offset along a longitudinal axis of the double cutting blade by 180 °. In the present case, however, any other possible arrangement of the cutting edges between 0 ° and 180 ° to each other on the respective scissor blade is understood as meaning a double cutting blade. Advantageously, combines the scissors, which has a designed as a double cutting blade and inventively detectable in different orientation scissor blade, two functions or scissor types in a pair of scissors, namely in the case of barber scissors both a hair clipper for "normal" cutting hair and a modeling scissors for reinforced Thinning of hair as defined above. So there are no longer two separate scissors required for the uses mentioned. The same applies in the case of a craft scissors, in which a corresponding double cutting blade can be changed in the same way in his orientation and found to

to produce different, for example even or odd or different odd, cut lines or cutting geometries.

In a preferred embodiment, the scissors comprises two scissor blades, which are each designed as a double cutting blade. In this embodiment, an orientation of the second scissor blade in such a first position or a second position can be determined that in the first position, a first blade of the second scissor blade cooperates with the first scissor blade and in the second position, a second blade of the second scissor blade with the first Scherenblatt cooperates. In other words, the respective scissor blade is configured as a turn sheet and it is possible that the respective effective cutting edge, in particular therefore between a smooth cutting edge and a toothed cutting edge, can be changed by turning the scissor blade. In such a pair of scissors, which has two scissor blades each designed as a double cutting blade, it is advantageously possible to combine three functions or scissors types in a pair of scissors, namely in the case of a barber scissors in addition to the above-mentioned hair cutting scissors and modeling scissors also a thinning scissors for easy thinning Hair in the sense of the above

Definition. So it's no longer three separate scissors for the mentioned

Uses required. The same applies in the case of a craft scissors, in which the number of possible cut lines or cutting geometries

can be increased accordingly. Advantageously, the orientation of the first and / or the second scissor blade means an orientation mechanism changeable and lockable. In this case, each scissor blade is preferably assigned an orientation mechanism. At two

Scissors with double cutting blade includes the scissors so two

Orientation mechanisms. The respective orientation mechanism may comprise in an advantageous embodiment, a spring element, a pin member and a form-locking locking element acting together to change the orientation or position of the respective scissor blade and determine. These arranged to connect the scissors blade with an associated handle of the scissors between the scissor blade and the handle elements can then act together so that the scissors blade pulled in the respective orientation or position along the longitudinal axis of the pin member of the spring element in the direction of the associated handle of the scissors is, whereby the locking element is effective and the scissor blade is positively detected on the handle. To change its orientation or position of the respective scissor blade is then against the parallel to the longitudinal axis of the pin member acting spring force of the spring element away from the associated handle to move. As a result, the positive connection of the locking element is canceled and a change in the respective other orientation or position can be made, in particular by a rotation about the longitudinal axis of the pin member.

Particularly preferred is the orientation of the first and / or the second

Scissor blade by turning about its respective longitudinal axis, in particular by turning by 180 °, from the first position to the second position transferred and vice versa from the second position to the first position and transferred

especially in each of these positions detectable. This allows the different configurations described below, and thus the

set different types of scissors.

A distance of the scissors blade from the orientation mechanism is not necessarily provided for the transfer from the first position to the second position. It is therefore possible that the respective scissor blade remains inextricably and thus permanently, in particular also when changing the position, connected to the respective orientation mechanism. In an optional and advantageous embodiment, the first and / or the second scissor blade with the associated However, orientation mechanism releasably connected and this with a

provided suitable connection element. The first and / or the second

The scissors blade can then be releasably attached to the respective orientation mechanism and removed from the respective orientation mechanism to outside the orientation mechanism, the position or

Change orientation of each scissor sheet and only by renewed

Attach to the orientation mechanism. In a particularly advantageous embodiment of the invention, the orientation mechanism then comprises a fastening device for releasably securing the respective

Scissor blade. In particular, it is advantageous if the fastening device is positively connected to the complementary connecting element of the respective

Scherenblatts acts, for example in the form of a plug-in mechanism or

Detent mechanism. Just as advantageously, the releasable connection can be magnetically assisted when the scissor blade and fastening device are magnetic, as is known, for example, from tools with bit attachments.

Advantageously, it is provided that each scissor blade is associated with a Beck, wherein each Beck includes a handle in the usual way. About the associated

Orientation mechanism, each scissor blade is attached to the associated handle. The associated orientation mechanism or its attachment device connects the respective scissor blade with the associated handle and is in this case arranged in particular on a side facing away from the respective handle side of the hinge point.

Advantageously, it is also provided that in each case the first cutting edge of the respective scissor blade of the second cutting edge of the respective scissor blade,

especially in terms of their geometry and thus also in terms of their function, is different. It is particularly advantageous in this sense provided that the first cutting edge of the respective scissor blade smooth and the second cutting edge of the respective scissor blade is formed toothed.

Depending on the design of the one or both double cutting blades, the scissors in the case of barber scissors is used as a hair trimmer when two smooth cutting the scissor blades interact, used as a modeling scissors, if ever a smooth and a toothed edge of the scissor blades Interaction, and can be used as a thinning scissors when two serrated blades of the scissor blades cooperate. Correspondingly, a craft scissors for different straight and / or odd cut lines or cutting geometries can be adjusted and used

Likewise claimed is a use of the scissors according to the invention as a hairdressing scissors, modeling scissors or thinning scissors. Advantageously, the present invention causes a change of use or function change between the individual uses or functions can be performed quickly and easily. The same applies in the case of a craft scissors for the change between different cutting lines or cutting geometries.

An embodiment of the invention will be explained in more detail with reference to the following description. Show it:

The scissors 1 comprises two mutually movable and thereby cooperating scissor blades 8, 9, wherein the first scissor blade 8 part of a fixed in the operation of the scissors 1 first Beck 10 and the second scissor blade 9 is part of a movable during the operation of the scissors 1 second Beck 11. The two Becks 10, 1 1 have to operate the scissors 1, that is, for opening and closing the scissors 1, in each case a handle 2 and 3, respectively. At each handle 2 or 3 is a first or second handle eye 4 or 5 formed. On the first handle eye 4, a finger rest 6 is also attached for applying the finger when operating the scissors 1.

The two Becks 10, 11 are connected to each other in a conventional manner at a hinge point 7. The hinge point 7 is located between the handle eyes 4, 5 and the scissor blades 8, 9. Preferably, a hinge screw may be provided at the hinge point 7, around which the Becks 10, 1 1 articulated towards each other and

away from each other, in the sense of opening and closing the scissors 1 are movable.

FIG. 2 shows a detailed illustration of a scissor blade to which scissor blades 8 and 9 correspond. As can be seen from FIG. 2, this is

Scissor blade 8, 9 as a double cutting blade with a smooth cutting edge 8a, 9a and one, preferably oppositely arranged, toothed cutting edge 8b, 9b formed. In addition, the scissor blade 8, 9 has a schematically illustrated

Connecting element 13 for attachment to the below described

Orientation mechanism 12 on. Trained as a double cutting blade

Scissor blades are known per se from the prior art and usually have oppositely disposed cutting edges. In the context of this

The invention is to be understood as a scissors blade with double cutting blade of each scissor blade, which has two functional blades 8a, 8b, 9a, 9b. The functional cutting edges 8a, 8b, 9a, 9b need not be arranged opposite at an angle of 180 ° along the longitudinal axis L of the respective scissor blade 8, 9 as shown, but can also at a smaller angle, for example between 180 ° and 90 ° be spaced apart. By functioning is meant that the cutting edges 8a, 8b, 9a, 9b are formed in the sense of the above definition as ungezahnte, smooth or toothed cutting edges, which are particularly suitable for cutting or thinning of hair.

Detailed views of the scissors 1 according to the invention, in particular their scissor blades 8, 9 in four different configurations A, B, C and D are shown in FIGS. 3a to 3d. The four configurations result from the combination of two different orientations or positions I and II, in which each of the two scissor blades 8, 9 can be determined. Under the orientation of the scissors blade 8, 9 is in particular the orientation of the scissor blade 8, 9th relative to its longitudinal axis L and in particular relative to the respective one

associated handle 2, 3 to understand. This is also clear from the description below.

3a shows the configuration A, wherein the first scissor blade 8, which is designed as a double cutting blade, with its first, in particular smooth, cutting edge 8a cooperates with the second scissor blade 9 and

Accordingly, the second scissor blade 9 faces. This corresponds to the first position I of the first scissor blade 8. Also, the second scissor blade 9 is formed as a double cutting blade, wherein the first, in particular smooth blade 9a, cooperates with the first scissor blade 8 and accordingly the first scissor blade 8 faces. This also corresponds to the first position I with respect to the second scissor blade 9. In the configuration A, therefore, the smooth first blades 8a, 9a face one another, and cooperate in such a way that the scissors 1 can be used as hairdressing scissors or slicers.

In a second configuration B, which is shown in FIG. 3b, this is known as

Double cutting blade designed first scissor blade 8 relative to the configuration A in its orientation changed. Preferably, by rotating about a longitudinal axis L of the first scissor blade 8, in particular by turning by 180 °, the first scissor blade 8 has been transferred to a second position II different from the first position I. In this second position II, a second, in particular toothed, cutting edge 8b of the first scissor blade 8 now interacts with the second scissor blade 9 and accordingly faces the second scissor blade 9. The second scissor blade 9 corresponds in particular with respect to its orientation or determination in the first position I the second scissor blade 9 of Figure 3a. In the configuration B, therefore, the toothed second blade 8b and the smooth first blade 9a face each other. In this configuration B the scissors 1 can be used as a modeling scissors.

The scissors 1 can be used as a modeling scissors in the configuration C shown in FIG. 3c. The configuration C essentially corresponds to the configuration B, but the first scissor blade 8 is fixed in position I and the second scissor blade 9 in position II. The orientations of the scissor blades 8 and 9, which are changed with respect to FIGS. 3 a and 3 b, are likewise by turning about the respective longitudinal axis, particularly preferably by turning by 180 °, from the first position I to the second position II and vice versa. In the

Configuration C are thus the smooth first cutting edge 8a and the toothed second cutting edge 9b facing each other and act together in such a way that the scissors 1 can be used as a modeling scissors.

In a fourth configuration D, shown in FIG

Double cutting blade designed scissor blades 8 and 9 compared to

Configuration A both changed in their orientation. In this configuration D, the first scissor blade 8 is therefore in the second position II, in which the second, in particular toothed, cutting edge 8b faces the second scissor blade 9 and cooperates with the second scissor blade 9. Also, the second scissor blade 9 is in the configuration D in the second position II, in which the second, in particular toothed, cutting edge 9b facing the first scissor blade 8 and cooperating with the first scissor blade 8. In the configuration D, therefore, the toothed, second cutting edges 8b, 9b face each other and cooperate in such a way that the shear 1 can be used as a thinning scissors.

It is therefore possible that the scissors type and thus the function of the scissors as mentioned above is changeable by a change in orientation of the respective scissor blade 8 and / or 9 from the first position I to the second position II or vice versa. In the respective orientation or position I, II, the scissor blade 8, 9 can be detected.

Advantageously, the orientation of the first and / or second scissor blade 8, 9 can be changed and fixed in each case by means of an associated orientation mechanism 12. The orientation mechanism 12 in the present case also includes a

Fastening device, in which the respective scissor blade 8, 9 with the

Connecting element 13 a key-lock principle following in the desired position I or II, but not with a deviating orientation or position, is plugged and thus detectable. The respective scissor blade 8, 9 is thereby releasably connected to the associated orientation mechanism 12. For releasably securing the scissor blade 8, 9, the respective orientation mechanism 12 thus comprises a receptacle for the scissor blade 8, 9 or the connecting element 13 Scissor blade 8, 9, it is also possible that the scissor blade 8, 9 in the

Orientation mechanism 12 can be fastened such that an unwanted

Slipping out of the scissors blade 8, 9 is prevented from the orientation mechanism 12. This is for example an additional in the

Orientation mechanism existing, for example, positively acting locking mechanism in the manner of a latching mechanism or

Plug-in mechanism possible, for which the connecting element 13 is then formed accordingly. However, it is not absolutely necessary for the orientation change according to the invention of the scissors blade 8, 9 or for the transfer of the respective scissor blade 8, 9 from the first position I to the second position II, that the scissor blade 8, 9 separated from the orientation mechanism 12 and its attachment device becomes. Instead, this can also be carried out if no connection element 13 is provided for releasable attachment, but a permanent connection of the respective scissor blade 8, 9 is realized with the associated orientation mechanism 12.
