Description

[Technical Field]

[0001] The present invention relates to hair-cutting scissors used in the barber or beauty industry for cutting hair. [Background technology]

[0002] Conventionally, a technique in this field is disclosed in Japanese Patent No. 5922213. The combing scissors described in this publication are provided with a hair escape space, which allows the scissors to be made lighter, thereby enabling fine hair treatment. Furthermore, since tangled hair can be released into this hair escape space, treatment that is affected by tangled hair can be avoided, thereby facilitating treatment that allows fine adjustment of hair. The roots of tangled hairs are cut by entering the cutting grooves in the cutting area. The non-cutting area of ​​the comb section also functions as a comb, so it can remove tangles above the hair to be cut and ensures that the hair enters the cutting grooves in the cutting area.

[0003] [Patent Document 1] Patent No. 5922213 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional thinning scissors described above, the non-cutting area of ​​the comb portion functions as a comb, so it can remove tangles above the hair to be cut and functions to ensure that the hair enters the cutting edge grooves in the cutting area.However, during treatment, when tangled hair is released from the non-cutting area of ​​the comb portion into the hair escape space, the groove between the comb portion at the rear end of the non-cutting area of ​​the comb portion and the comb portion at the front end of the hair escape space is deep, so the hair gets caught in the comb portion at the rear end of the non-cutting area of ​​the comb portion, and the tangled hair cannot be released smoothly into the hair escape space.

[0005] To provide combing scissors that can smoothly release tangled hair into a hair escape space and facilitate fine adjustment of hair. [Means for solving the problem]

[0006] The present invention provides a pair of thinning scissors in which a first scissors half provided with a cutting edge groove for catching hair and a second scissors half provided with a rod blade are connected by a pivot, The first scissors half is provided with comb portions located on the tip side, and the front row of the comb portions has a cutting area in which the cutting edge grooves are provided, and the rear row of the comb portions has a non-cutting area in which the cutting edge grooves are not provided, The second scissors half is provided with cutting blades corresponding to the cutting area and the non-cutting area, A hair escape space is provided between the pivot and the non-cutting area, where the first scissors half and the second scissors half do not come into contact with each other, In the hair escape space, the first scissors half has a short tooth region in which short teeth that do not reach the second scissors half are formed, Between a first end tooth located at a rear end of the non-cutting region and a second end tooth located at a front end of the short tooth region, there is formed an intermediate tooth region in which intermediate teeth that become progressively shorter from the first end tooth toward the second end tooth are formed, A bottom-up portion is formed between the first end tooth located at the rear end of the non-cutting region and the end tooth located at the front end of the intermediate tooth region, with the bottom of the tooth groove located toward the tooth tip.

[0007] In these thinning scissors, the provision of a hair escape space makes it possible to make the scissors lighter, thereby enabling fine hair treatment.Furthermore, a raised bottom portion is formed between the first end tooth located at the rear end of the non-cutting area and the end tooth located at the front end of the intermediate tooth area, with the bottom of the tooth groove located toward the tooth tip.This means that tangled hair can be smoothly released into this hair escape space without becoming tangled in the first end tooth located at the rear end of the non-cutting area, thereby avoiding treatment that is affected by hair tangling and making it easier to perform fine hair treatment. The roots of tangled hairs are cut by entering the cutting grooves in the cutting area. The non-cutting area of ​​the comb section also functions as a comb, so it can remove tangles above the hair to be cut and ensures that the hair enters the cutting grooves in the cutting area.

[0008] In this combing scissors, first, the comb portion located at the tip side of the first scissors half 2 is brought into contact with the scalp, and the comb portion is used to lift the hair crossings at the roots of the hair. Then, the first scissors half 2 is moved from the roots of the hair to the tips of the hair through the non-cutting region S2, the intermediate tooth region S3, the short tooth region S4, and the hair escape space R. Next, the hair is released into the non-cutting area S2, the intermediate tooth area S3 and the short tooth area S4, and the comb blades are used to undo the crossing of the hair. After that, the comb part, which is the cutting area S1 located at the tip of the first scissors half 2, and the cutting blade part of the second scissors half can cut the crossing hairs one by one from the root, allowing the crossed hairs to be cut smoothly. [Effects of the Invention]

[0009] According to the present invention, it is possible to easily carry out a smooth fine adjustment of crossed hairs. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a front view showing an embodiment of thinning scissors according to the present invention. [Figure 2] FIG. 2 is an enlarged view of a main part showing the thinning scissors in an open state. [Figure 3]FIG. 10 is a diagram showing the state of use of thinning scissors. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, preferred embodiments of the thinning scissors according to the present invention will be described in detail with reference to the drawings. The tip side of the thinning scissors will be referred to as the "front" and the finger insertion ring side of the thinning scissors will be referred to as the "rear".

[0012] When observing the scalp with a microscanner, although there are individual differences, people with a lot of hair will have 4 or 5 hairs coming out of one pore, which is related to hair density. Also, although the way hair grows varies, hair grows in a crisscross pattern from the pores, and as hair grows in bundles with irregular crosses and rotations, the hair that grows out has a natural twist or kink.

[0013] The angle at which hair grows and the direction of hair flow (the flow of hair from the scalp) cause hair to cross, and this tangling creates multiple strands of hair from the beginning to the ends. If we compare it to nature, it is like an untended bamboo forest. These crossings, in relation to the direction of hair flow, cause the hair to become tangled with each other, forming clumps and causing them to stick together. This causes splitting in the bangs and hair strands. It is difficult to untangle these crossings with a comb, and it is particularly difficult as there are limitations to untangling from the roots.

[0014] Therefore, rather than combing to remove the crossings, we found that it was effective to increase the number of crossings and overlaps between hairs. By performing treatments that reduce the number of crossings, diffused reflection by the hair is reduced, resulting in a glossy shine and a smooth feel to the touch.

[0015] Therefore, the following thinning scissors 1 were invented.

[0016] As shown in Figure 1, thinning scissors 1 have a first scissors half 2 provided with a comb portion 2a and a second scissors half 3 provided with a rod blade 3a, connected by a pivot 4. A finger insertion ring 2b is provided at the base end of first scissors half 2, and a finger insertion ring 3b is also provided at the end of second scissors half 3.

[0017] As shown in Figures 2 and 3, the first scissors half 2 has a comb portion 2a located on the tip side, and the front row of the comb portion 2a has a cutting area S1 in which multiple first comb teeth 11 (e.g., seven evenly spaced apart) each having a cutting edge groove 10 are arranged in a row.

[0018] The rear row of the comb portion 2a has a non-cutting region S2 in which a plurality of second comb teeth 12 (for example, four evenly spaced apart) are arranged in a row and do not have cutting edge grooves 10. The first comb teeth 11 gradually become longer from the front side, and the second comb teeth 12 gradually become longer toward the rear side so as to be continuous with the first comb teeth 11.

[0019] The rod blade 3a of the second scissors half 3 has a cutting blade portion 13 extending to correspond to the cutting region S1 and the non-cutting region S2, and a stop blade portion 14 extending rearward from the cutting blade portion 13.

[0020] Between the pivot 4 and the non-cutting region S2, a hair escape space R is provided, where the first scissors half 2 and the second scissors half 3 do not come into contact. This hair escape space R extends in the longitudinal direction of the thinning scissors 1 behind the non-cutting region S2, and has a length in the longitudinal direction that is at least twice the combined length of the cutting region S1 and the non-cutting region S2.

[0021] As shown in FIG. 3, the provision of a hair escape space R in these thinning scissors 1 allows the scissors 1 to be lightweight, thereby enabling fine treatment of the hair A. Furthermore, tangled hair A can be allowed to escape into this hair escape space R, preventing treatment that would be affected by tangled hair A on the head H, facilitating fine adjustment of the hair A. The roots of tangled hair A enter the cutting grooves 10 (see FIG. 5(b)) formed in the cutting region S1 and are cut. Furthermore, the non-cutting region S2 of the comb portion 2a functions as a comb, so that tangles can be removed above the hair A to be cut on the head H, and the non-cutting region S2 functions to reliably insert the hair A into the cutting grooves 10 in the cutting region S1.

[0022] Furthermore, the cutting edge groove 10 of the first comb tooth 11 is formed as a curved recess that can accommodate a single hair A. The second comb tooth 12 is tapered and does not have a cutting edge groove 10. This configuration allows for fine cutting, which makes it easier to further fine-tune the length of the hair A.

[0023] As shown in Figures 2 and 3, in the hair escape space R, the first scissors half 2 has a short tooth region S4 where short teeth 16 are formed that do not reach the second scissors half 3. The multiple short teeth 16 (for example, seven evenly spaced apart) do not have cutting edge grooves 10 and are short in length, about 1 to 3 mm. By adopting this configuration, the short teeth 16 can perform a combing function even on hair A that has become tangled in the hair escape space R.

[0024] Between the first end tooth 12a located at the rear end of the non-cutting region S2 and the second end tooth 16a located at the front end of the short tooth region S4, there is an intermediate tooth region S3 where intermediate teeth 17 are formed, the length of which gradually decreases from the first end tooth 12a to the second end tooth 16a. In this case, there are multiple intermediate teeth 17 (for example, two). By adopting this configuration, good combing function can be achieved even between the non-cutting region S2 and the short tooth region S4.

[0025] Furthermore, a bottom-raised portion 20 is formed between the first end tooth 12a located at the rear end of the non-cutting area S2 and the intermediate tooth 17a at the tip, with the bottom of the tooth groove located toward the tooth tip, so that hair can be smoothly guided to the intermediate tooth area S3 and short tooth area S4 without getting tangled in the end tooth 12a. This bottom-raising portion 20 is formed in the tooth direction of the end teeth 12a from the first scissors half 2, and the depth of the tooth groove between the end teeth 12a and the intermediate teeth 17a at the tip is formed shallower than the tooth groove between the second comb teeth 12, so that hair can be smoothly released into the hair escape space R without getting tangled in the end teeth 12a.

[0026] The bottom-raising portion 20 is provided between the first end tooth 12a located at the rear end of the non-cutting region S2 and the intermediate tooth 17a at the tip, but it may also be provided between the intermediate tooth 17a at the tip and the intermediate tooth 17a at the rear end.If formed in this way, the depth of the tooth groove gradually approaches that of the short tooth region S4, so that hair can escape more smoothly from the intermediate tooth region S3 to the short tooth region S4 into the hair escape space R without becoming tangled in the end tooth 12a. The depth of the tooth grooves in the short tooth region S4 gradually approaches the depth of the tooth grooves in the short tooth region S4, so that the hair can be smoothly released into the hair release space R.

[0027] A step 18 that is one step lower is provided at the rear of the cutting blade portion 13. By adopting such a configuration, it is possible to easily guide the hair A into the hair escape space R during treatment.

[0028] A method for cutting hair A with the thinning scissors 1 will now be described. Hair grows in different directions from one hair follicle, and adjacent hair follicles cross over each other, so this crossover affects the ends of the hair. As a result, hair grows in a stronger direction, the hair becomes voluminous, and it is difficult to achieve the hairstyle you want. As shown in Figure 3, first, the comb part 2a located at the tip side of the first scissors half 2 is used to lift the hair crossing at the root of the hair, and the first scissors half 2 is moved from the root to the tip of the hair through the non-cutting area S2, the middle tooth area S3, the short tooth area S4 and the hair escape space R. Between the first end tooth 12a located at the rear end of the non-cutting area S2 and the intermediate tooth 17a at the tip, a bottom-raised section 20 is formed in which the bottom of the tooth groove is located toward the tooth tip, allowing hair to smoothly escape to the intermediate tooth area S3 and short tooth area S4 without getting tangled in the end tooth 12a.

[0029] Therefore, the hair intersections are resolved by the comb teeth in the non-cutting region S2, the intermediate tooth region S3, and the short tooth region S4. Then, the comb portion 2a, which is the cutting area S1 located on the tip side of the first scissors half 2, This allows the cause of hair crossing to be cut from the root, one strand at a time, and the cause of hair crossing can be removed.
