Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to card scissors mainly used in barber shops and beauty salons.

[0002]

2. Description of the Related Art Generally, combing scissors for hairdressing and cosmetics have a comb blade in which comb teeth are juxtaposed through a cut groove and a bar blade having a substantially straight blade, which are pivotally supported by a pivot shaft. However, the hair is cut at the intersection of the cutting edges of each other. Further, the hair left in the cut groove without being cut is pulled out from the cut groove by moving the combing scissors to the hair tip side in the closed state.

By the way, when combing scissors are obliquely inserted into the hair and it is attempted to pull it out as it is, the hair left in the notch without being cut is squeezed and damaged by the corners of the comb tooth body. There is. Therefore, for example,
In Japanese Patent No. 56882, as shown in FIG.
There is proposed a carding scissor in which a chamfered portion 102b is formed by chamfering a corner portion of each comb tooth body (comb tooth-shaped protrusion) 102 constituting the above. According to the publication, the carding scissors shown in FIG.
As shown in FIG.
Even if the hair h is slanted with respect to 3, the chamfered portion 102b comes into contact with the hair h. Therefore, when the comb scissors are moved in the direction of arrow a, the hair h is pulled out from the cut groove 103 without squeezing. You can do it.

[0004]

However, even if the corners of each comb-tooth body 102 are chamfered as in the above-mentioned publication, the cut groove 103 for the uncut hair is also left.
The "removal" from the hair was not smooth, and the hair was often pulled, and the cuticle on the surface of the hair was damaged. that is,
The reason is as follows.

That is, FIG. 8 shows a main part of a general carding scissors for hairdressing and beauty treatment, FIG. 9 shows a cross section taken along the line CC of FIG. 8 (however, the scissors are closed), and FIG. 10 shows FIG. And a cross section taken along the line D-D of FIG. 9, respectively. In a general carding scissor 100 in which a comb blade 101 in which comb teeth 102 are juxtaposed through a cut groove 103 and a substantially straight blade rod 104 are pivotally supported by a pivot shaft 105 so as to be openable and closable As shown in FIG. 9, the comb blade 101 has the thickest portion at the peak 106, and has a cross-sectional shape in which the thickness gradually decreases from the peak 106 toward the tip of the comb tooth body 102 in a substantially arc shape. is doing. Comb blade 1
The thickness of the thickest part of No. 01 (that is, the portion of the peak 106) is usually about 3 mm from the relationship of the plate thickness of the steel plate used as the material. On the other hand, the groove width of the cut groove 103 varies depending on the carding scissors, but is usually about 0.5 to 1 mm. Further, as shown in FIG. 9, when the scissors are closed, the rod blade 10
No. 4 cutting edge line 104a and groove bottom portion 103 of the cut groove 103
A predetermined gap is formed between the hair and a, and the uncut hair is pushed into this portion.

Also, as shown in FIG. 10, the length L of the cut groove 103 in the thickness direction of the comb blade 101 in the vicinity of the groove bottom into which the uncut hair is pushed by the rod blade 104.
Is slightly shorter than the thickness dimension of the thickest part of the comb blade 101, and the cut groove 103 in this part has an elongated cross-sectional shape having a large ratio (L: W) of the length L to the groove width W. have. Therefore, when the combing scissors are obliquely inserted into the hair, the uncut hair h is
Since the hair h is bent inside and outside the cut groove 103 like this, the hair h is bent from the cut groove 103 by moving the combing scissors in the arrow B direction as well as the arrow B direction in the figure because the hair h is bent. Even when trying to pull out the hair, the frictional resistance was increased and the hair could not be pulled out smoothly, giving the sensation that the hair was pulled or damaging the cuticle on the hair surface.

The bending of the hair h described above is
Width W of length L in the vicinity of the groove bottom of the cut groove 103
Since it is caused by a large ratio (L: W) with respect to the above, even if each comb tooth body 102 is chamfered as described in Japanese Utility Model Laid-Open No. 56-56882, it is basically solved. It wasn't something.

The present invention has been made to solve the above-mentioned problems of the prior art. Even when the combing scissors are obliquely inserted into the hair, the uncut hair is left in the cut groove. An object of the present invention is to provide carding scissors which can be smoothly removed and can prevent damage to hair.

[0009]

In order to achieve the above object, the present invention provides a comb blade having comb teeth arranged side by side through a slit groove and a bar blade having a substantially straight blade on a pivot shaft. In combing scissors that pivotally support and cut hair at the intersection of the cutting edges of each other, the comb blade has the thickest part formed between the cutting edge line of the bar blade and the tip of the comb tooth body when the scissors are closed. At the same time, the cross-sectional shape is such that the portion between the blade edge line of the bar blade when the scissors are closed and at least the groove bottom portion of the cut groove is thinner than the thickest portion.

Further, in the above construction, the comb blade has a cross-sectional shape in which the thickness gradually decreases from the thickest portion toward the ridge side.

Further, comb scissors for cutting hair at a crossing point of the blades of a comb, in which comb teeth are juxtaposed in parallel with each other through a cut groove, and a bar blade of a substantially straight blade are pivotally supported by a pivot shaft. In the above, the comb blade is configured such that the crest is formed to have the thickest wall and a step is formed between the crest and the thin-walled comb tooth body.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A combing scissors for hairdressing and cosmetics according to an embodiment of the present invention will be described below with reference to FIGS. The carding scissors generally designated by the numeral 1 in FIG. 1 are comb blades 2 and rod blades 3.
When and are pivotally supported by a pivot shaft (screw) 4 and the scissors are closed from the open state, the hair is cut at the intersection of the blade edges of each other. A handle 6 having a finger ring 5 at the tip thereof is continuously provided on the comb blade 2, and a little finger hook 7 is projectingly provided at the tip of the finger ring 5. On the other hand, a handle 9 having a finger ring 8 at its tip is continuously provided on the rod blade 3, and a side surface of the finger ring 8 is
When the scissors are closed, a protrusion-shaped contact portion 10 is provided for contacting the finger hook ring 5 on the comb blade 2 side to regulate the opening of the comb blade 2 and the rod blade 3.

The comb blade 2 has a plurality of comb tooth bodies 11, 11, ...
Are arranged in parallel with each other through the cut grooves 12, 12, .... The base end portion of each comb tooth body 11 is connected and integrated with a ridge 13 extending in the longitudinal direction of the comb blade 2. Further, as shown in FIG. 2, a cutting edge 15 having a V-groove-shaped recess 14 is formed at the tip of each comb tooth body 11. In addition, in this embodiment, as shown in FIG. 1, each comb tooth body 11 is curved and formed in an arc shape centered on the pivot shaft 4 in a plan view.

On the other hand, the bar blade 3 is formed in a substantially straight blade shape. Reference numeral 3a indicates a cutting edge line of the rod blade 3. The carding scissors 1 pivotally supporting the comb blade 2 and the bar blade 3 as described above, when the scissors are closed, that is, the contact portion 10 of one finger ring 8 is brought into contact with the side surface of the other finger ring 5. When this is done, the cutting edge line 3a of the rod blade 3 and the groove bottom portion 12a of each cutting groove 12 of the comb blade 2
A predetermined gap is created between the gap and the gap, and the hair left uncut in the cut groove 12 is pushed in.

Here, in the carding scissors 1 according to this embodiment, the comb blade 2 has the following cross-sectional shape. That is, as shown in FIGS. 2 and 3, when the scissors are closed, the position corresponding to the cutting edge line 3a of the rod blade 3 and each comb tooth body 11 are shown.
The thickest part 17 having the largest wall thickness t is formed in the region α in the width direction between the tip (blade 15). Between the thickest portion 17 and the cutting edge 15, the blade surface is formed into a curved surface having an arcuate cross section, and is gradually linear from the thickest portion 17 toward the side edge on the ridge 13 side. It is formed in a thin sectional shape. Therefore, from the position corresponding to the cutting edge line 3a of the rod blade 3 when the scissors are closed, each cutting groove 12
The region β in the width direction up to the groove bottom portion 12a is naturally thinner than the thickest portion 17.

Since this carding scissors 1 is constructed as described above, the wall thickness t of the thickest part 17 of the comb blade 2 is the wall thickness of the thickest part (the peak 106 part) in the conventional carding scissors 100. Even when the width W of the cut groove 12 is the same as the width W of the cut groove 103 in the conventional carding scissors 100, as shown in FIG. 3 near the bottom of the groove (the area β
(Corresponding to), the length L of the cut groove 12 in the thickness direction of the comb blade 2 is significantly shorter than in the conventional case.

Therefore, the cross section of each of the cut grooves 12 in the vicinity of the groove bottom has a rectangular shape in which the ratio (L: W) of the length L to the width W is small, so that the combing scissors 1 are obliquely attached to the hair. Even when it is inserted (that is, in a state where the longitudinal direction of the hair and the longitudinal directions of the comb blade 2 and the bar blade 3 intersect in an inclined manner), the inside and outside of the cut groove 12 of the hair h left uncut as shown in FIG. There will be a slight bend at. Therefore, even when the carding scissors 1 are moved in the direction of arrow A in the figure (direction substantially perpendicular to the comb blade 2), they are moved in the direction of arrow B (direction substantially parallel to the hair h) (actual use). In the state, it is more often moved in this direction), but since the frictional resistance between the comb tooth body 11 and the hair h becomes small, the cut groove 12
The hair h can be pulled out smoothly from the hair, and the hair is not pulled and the cuticle on the hair surface is not damaged.

Further, if the comb blade 2 is formed thin as a whole, the comb blade 2 becomes lighter, so that the comb blade 2 is repelled by the hair at the time of cutting (the comb blade 2 is shaken by the reaction force when cutting the hair). The situation arises, and the mass balance between the comb blade 2 and the handle 6 is deteriorated, which results in scissors having a poor usability.
In this combing scissors 1, since the mass of the comb blade 2 is ensured by providing the thickest part 17 near the tip of the comb tooth body 11 of the comb blade 2, the mass of the comb blade 2 is secured, and the comb blade 2 is repelled by the hair or the mass balance is lost. There is no need to do so, and a suitable feeling of use can be obtained.
Further, although the peak 13 is thin, there is no problem in strength and the carding scissors have sufficiently high practicality.

FIGS. 5 (a) and 5 (b) each show a carding scissors according to another embodiment of the present invention in a cross section corresponding to FIG. 3, and correspond to the carding scissors 1 of the above embodiment. The same reference numerals are given to the constituent elements to be described, and the duplicated description will be omitted. In the carding scissors shown in FIG. 5 (a), the blade surface from the thickest portion 17 of the comb blade 2 to the peak 13 is formed into a concave surface which is upside down in cross section. With such carding scissors, the thickness of the comb blade 2 is minimized in the entire region from the cutting edge line 3a of the bar blade 3 to the groove bottom portion 12a of the cutting groove 12 when the scissors are closed, so that the hair remaining after cutting is removed. Becomes even smoother. Further, similar to the carding scissors 1 of the above-described embodiment, the comb blade 2 can be easily cut even with this cross-sectional shape, and the appearance (aesthetic appearance) is excellent.

On the other hand, in the carding scissors shown in FIG. 5 (b), the peak 13 of the comb blade 2 is formed to be slightly thicker than the area from the cutting edge line 3a to the groove bottom 12a. In such carding scissors, the mass of the peak 13 is added, so that FIG.
The mass of the comb blade 2 as a whole can be made larger than that of the carding scissors shown in (a).

FIG. 6 shows a card scissors according to still another embodiment of the present invention in a cross section corresponding to FIG. 3, and the components corresponding to the card scissors 1 are given the same reference numerals. Then, the overlapping description is omitted. In this carding scissors, the peak 13 of the comb blade 2 is formed to be thickest,
The portion of the comb tooth body 11 is formed thin as a whole. A step portion 13a is formed between the thick-walled peak 13 and the thin-walled comb tooth body 11 due to the difference in thickness between them. As shown in FIG. 9, the conventional carding scissors move from the peak 106 to the comb tooth body 10.
2 In contrast to the cross-sectional shape that gradually becomes thinner toward the tip end side, in the carding scissors of this embodiment, the wall thickness is abruptly changed at the step portion 13a between the peak 13 and the comb tooth body 11. And even with such a configuration, the rod blade 3 when the scissors are closed
The area from the cutting edge line 3a to the groove bottom portion 12a of the cut groove 12 is thinned to smoothly remove the hair, and the ridge 1
With the mass of 3, the mass of the comb blade 2 as a whole can be secured.

However, in order to secure the mass necessary for the comb blade 2 in such a configuration, for example, the thickness of the peak 13 is set to 4
It is necessary to make it thicker than 5 mm or to widen the width W1 of the ridge 13 considerably, so that the appearance (aesthetic appearance) of the carding scissors is impaired and the ridge 13 becomes an obstacle and becomes difficult to use. May cause harmful effects. On the other hand, the thickest part 1 is provided between the tip line 3a of the bar blade 3 and the tip of the comb tooth body 11 when the scissors are closed as in the above embodiments.
With the configuration provided with 7, the appearance of the carding scissors will not be impaired and the usability will not be deteriorated.

Needless to say, the technical scope of the present invention is not limited to the above-mentioned embodiments, and the cross-sectional shape of the comb blade 2 is not limited to the shape shown in each of the above figures, but is arbitrary. Also. According to the constitution of the present invention,
Naturally, it is also possible to combine and implement the configuration of chamfering the corners of each comb tooth body as described in Japanese Patent No. 6882.

[0024]

As described above, according to the present invention,
By thinning the wall thickness of the comb blade near the groove bottom of each cut groove, even if the combing scissors are obliquely inserted into the hair, the uncut hair can be smoothly removed from the cut groove. Can prevent damage to the hair,
Moreover, by ensuring the mass of the comb blade, it is possible to provide the carding scissors that can obtain a suitable usability.

If the comb blade has a cross-sectional shape in which the thickness gradually decreases from the thickest part toward the crest side, the comb blade is easy to cut and has a good appearance. Is obtained.
