Description

[Detailed description of the invention] FIELD OF THE INVENTION The present invention relates to scissors, particularly hair trimming scissors.

Conventionally, hair treatments, such as "'weave"
ve) Cutting'' to achieve a certain appearance and style required a painstaking and time-consuming process using ordinary scissors and a comb.

Thinning scissors are already known in which one plate is provided with a flat cutting edge and the other blade is provided with uniformly spaced fine teeth.

The purpose of such scissors is to make it appear as if the overall length of the hair has not been reduced but the bulk has been reduced from the perspective of others.

The appearance obtained with the thinning scissors is quite different from that according to the invention.

DE 721 672 discloses toothed scissors with specially constructed blades and grooves which, when used on tresses extending from the head, are capable of cutting the lower layer of hair.

An object of the present invention is to provide scissors that can be used for weave cutting and other special shapes quickly without requiring much skill.

Accordingly, the present invention comprises first and second blades, the first plate having a straight, flat inner edge, and the second plate having an inner edge divided longitudinally into a plurality of sections. the staggered sections have first and second types of edges, the edges of the at least one type extending over at least a portion of the length of the section when the scissors are closed; To provide scissors that are formed to leave a non-cutting opening between both blades.

Three specific types of scissors are as follows.

(i) the second route comprises a cut section and a completely uncut section;

(ii) said second plate having a cutting section and a section similar to thinning shears;

(iii) the second blade has a thinning shears-like section and a completely non-cutting section;

Implementation - Example Embodiments of the present invention will be described below with reference to the drawings.

The scissors shown have a first blade (1) and a second blade (3).
The first blade (1) has a straight, flat, blunt edge (2). the edge of the second blade (3) is divided into a plurality of sections along the edge;
The alternating sections are formed to provide first and second types of edges (4), (5).

In the embodiment shown in FIG. 1, the first edge (4) has a shallow V
It has a shaped cutting edge. This V-shape improves the cutting efficiency of the scissors.

The second edge (5) comprises a straight, flat, blunt edge which is recessed into the adjacent section of the blade.

Thus, when the scissor blades are brought together, the hair sandwiched between the cutting section (4) of the second blade (3) and the first blade (1) is cut, while the
The hair sandwiched between the blunt, recessed section (5) and the first blade (1) is left uncut. The result is a hairstyle in which the time-consuming and careful work of traditional scissors and combs is easily and quickly performed.

Figure 2A shows a modification of the scissors described above, in which the cutting edge is formed into a shallow curve (4A) rather than a V-shape.

The use of straight cutting edges is also possible within the scope of the invention.

The embodiment shown in FIG. 3 comprises a first edge (4) of the same type as shown in FIG. However, in this case, a straight and flat cutting edge (6
), the edges (6) having narrow cutting sections (7) and non-cutting recesses (8) along their length.
It is divided into.

Thus, the scissors selectively cut and thin the hair.

FIG. 3A shows a modification of the scissors of FIG. 3 with the modifications shown in FIG. 2A.

The embodiment shown in FIG. 4 has the blunt concave sections (5) in the embodiment shown in FIG. 1 staggered with the thinning sections (6) in the embodiment shown in FIG. Thinning or leaving it uncut.

FIG. 5A is a cross-sectional view of the aforementioned first plate (1) with a blunted inner edge (2). Cut the inner edge with a cutting edge (2A) as shown in FIG. 5B.
) may be formed sharply.

The size of the plate sections depends on the style desired; too large and too advantageous, too small and unobtrusive.

The section length is preferably in the range of 2.5 mm to 10 mm. A section length of approximately 5mm is preferred)
Particularly suitable for qru.
