To provide hair thinning scissors capable of efficiently thinning many hairs with a gap between the tip of each cutting blade and each comb tooth being enlarged.SOLUTION: Hair thinning scissors 1 are opened and closed by turning a cutting blade 2 and a thinning blade 3 around a support shaft 4. A blade part 20 of the cutting blade 2 is located on an outer side in an opening direction of a center line 4a passing through a center of the support shaft 4. Recessed parts 34 between the comb teeth 33 of the thinning blade 3 are formed up to an outer side in an opening direction of the extension line of a connection part 32 at least at a position near the support shaft 4. The recessed parts 34 between the comb teeth 33 of the thinning blade 3 are formed up to the outer side in the opening direction of the extension line of the connection part 32 at least at the position near the support shaft 4. Therefore, a gap formed between an inner side 20a which is a tip end of the cutting blade 2, and the recessed part 34 between the comb-teeth 33 is increased, so that many hairs 5, 6 can be efficiently thinned.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a hair thinning scissors used for grooming and beauty.

Background Art

[0002] Conventionally, in grooming and beauty, hair thinning scissors have been used for a hair thinning operation called thinning (see, for example, Patent Document 1). The hair thinning scissors include a cutting blade and a thinning blade rotatably supported on the cutting blade by a support shaft. The thinning blade is formed with a plurality of comb teeth spaced apart from each other, and when closed, a space is formed between the tip of the cutting blade and the comb teeth where hair remains. The hair is sheared between the blade formed at the tip of the comb teeth and the blade formed at the tip of the cutting blade. In order to improve the operability of the hair thinning scissors, it has also been proposed to shorten the length of the cutting blade with the comb teeth (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0004] As shown in FIG. 3 of Patent Document 1, the hair thinning scissors shear the hair sandwiched between the tip of the comb teeth and the tip of the cutting blade while leaving hair in the gap between the tip of the cutting blade and the comb teeth. However, in the conventional hair thinning scissors, as shown in FIG. 4 of Patent Document 1, the gap for leaving hair is small, and when there is a lot of hair, the hair cannot be sufficiently thinned, and it is necessary to repeat the operation many times. Even if the hair is sheared between the tip of the cutting blade and the tip of the comb teeth as in Patent Document 2, the gap for leaving hair does not become larger.

[0005] An object of the present invention is to provide a hair comb shear that can increase the gap between the tip of the cutting blade and the comb teeth and efficiently thin out a large amount of hair.

Means for Solving the Problems

[0006] The present invention has a cutting blade including a blade portion provided with a cutting edge, a handle portion serving as a handle, and a connecting portion connecting the blade portion and the handle portion, and a thinning blade including a blade portion provided with comb teeth, a handle portion serving as a handle, and a connecting portion connecting the blade portion and the handle portion. The cutting blade and the thinning blade intersect at a connecting portion, and the comb blade is rotatably supported by a cutting blade by a support shaft provided at the intersection portion. In a hair comb shear that can open and close between the cutting blade and the thinning blade, The blade portion of the cutting blade is outside in the opening direction from the center of the support shaft. The recess between the comb teeth of the thinning blade is formed outside in the opening direction from the extension line of the connecting portion at least at a position near the support shaft. It is a hair comb shear characterized by this.

[0007] In the present invention, the blade portion of the thinning blade projects outward in the opening direction from the connecting portion on the peak side, and the width in the rotation direction becomes wider. The comb teeth of the thinning blade are formed up to a position away from the cutting blade rather than the extension of the connecting portion toward the blade portion side. It is characterized by this.

[0008] In the present invention, the width of the thinning blade is 20% or more with respect to the width of the connecting portion. It is characterized by this.

Effects of the Invention

[0009] According to the present invention, the blade portion of the cutting blade is outside in the opening direction from the center of the support shaft. The recess between the comb teeth of the thinning blade is formed outside in the opening direction from the extension line of the connecting portion at least at a position near the support shaft. Therefore, the gap between the tip of the cutting blade and the comb teeth can be increased, and a large amount of hair can be efficiently thinned out.

[0010] Further, according to the present invention, the width of the comb teeth can be widened, and the width of the recess between the comb teeth can be increased.

[0011] Further, according to the present invention, the width of the comb teeth can be surely made wider than the width of the connecting portion, and the width of the recess between the comb teeth can be surely increased.

Modes for Carrying Out the Invention

[0013] Hereinafter, FIGS. 1 to 4 show the basic configuration of the hair comb 1 as an embodiment of the present invention in an open state, the closed state as an embodiment, the gap between the cutting edge and the comb teeth in the closed state, and the state of hair thinning, respectively. Depending on the drawings, the description of the corresponding parts described in other drawings may be omitted. The description of each figure is made along with the figure, but the description of the parts omitted in the figure may also be made using the reference numerals attached to other figures.

Examples

[0014] Figure 1 shows the basic configuration of the hairbrush scissors 1 according to the present invention in an open state. Figures 2 and 3 show the configuration of the hairbrush scissors 1 as an embodiment of the present invention in a closed state. The hairbrush scissors 1 include a cutting blade 2, a comb blade 3, and a support shaft 4. The cutting blade 2 includes a blade portion 20 provided with a shearing blade, a handle portion 21 serving as a handle, and a connecting portion 22 connecting the blade portion 20 and the handle portion 21. The comb blade 3 includes a blade portion 30 provided with comb teeth 33, a handle portion 31 serving as a handle, and a connecting portion 32 connecting the blade portion 30 and the handle portion 31. The cutting blade 2 and the comb blade 3 intersect at the connecting portions 222, 32, and the comb blade 3 is rotatably supported by the cutting blade 2 by a support shaft 4 provided at the intersection portions 22, 32, and the space between the cutting blade 2 and the comb blade 3 can be opened and closed. The cutting blade 2 has a shearing blade formed on the inner side 20a in the closing direction of the blade portion 20, and the outer side 20b in the opening direction becomes a peak. The comb teeth 33 are alternately formed with recesses 34 and have a shearing blade on the inner side 33a in the closing direction.

[0015] The blade portion 20 of the cutting blade 2 is located outward in the opening direction from the center line 4a passing through the center of the support shaft 4. The recesses 34 between the comb teeth 33 of the comb blade 3 are formed outward in the opening direction beyond the extension line of the connecting portion 32 at least at a position closer to the support shaft 4. That is, if the width of the connecting portion 32 of the comb blade 3 is w and the width between the inner side 30a and the outer side 30b of the blade portion 30 of the comb blade 3 is W, then w < W. In this embodiment, the width W of the blade portion 30 of the comb blade 3 is made 20% or more wider than the width w of the connecting portion 32. However, if W is made too large, it becomes difficult to manufacture the hairbrush scissors 1, so widening W with respect to w is set to 30% or less. Thereby, the width W of the comb blade 3 can be widened and the width of the recesses 34 between the comb teeth 33 can be increased. Also, the width W of the comb blade 3 can be surely made wider than the width w of the connecting portion 32, and the width of the recesses 34 between the comb teeth 33 can be surely increased.

[0016] FIG. 4 schematically shows a state in which thinning of hair 5 is performed between the blade portion 20 of the cutting blade 2 of the hair clipper 1 and the blade portion 30 of the comb blade 3. The hair 6 indicated by the broken line is cut between the shearing blade formed on the inner side 33a of the comb teeth 33 and the shearing blade formed on the inner side 20a of the blade portion 20 of the cutting blade 2. In the recess 34 between the comb teeth 33, the hair 6 is not cut. The blade portion 20 of the cutting blade 2 is outward in a direction opening from the center of the support shaft 4. The recess 34 between the comb teeth 33 of the comb blade 3 is formed outward in an opening direction beyond the extension line of the connecting portion 32 at least at a position closer to the support shaft 4. Therefore, the gap formed between the inner side 20a, which is the tip of the cutting blade 2, and the recess 34 between the comb teeth 33 can be increased, and a large number of hairs 5 and 6 can be efficiently thinned.
