Description

  The present invention relates to a replacement razor for use in a hair brush having a hair cutting function, a hair combing function, and a scalp massage function.

  For the purpose of cosmetic hair, it is widely practiced to comb the hair, partially cut excess hair, and adjust the hair style while massaging the scalp. For such operations, independent combing scissors and combs are used depending on the purpose, and hair combing and cutting have been traditionally performed. It is also known that a hair brush is employed for the purpose of massaging the scalp in conjunction with hair adjustment.

However, in the above-mentioned background art, it is necessary to use a brush for hair in addition to combing scissors and combs, and the work requires skill and so-called hang, so there is a drawback that it lacks usability. Therefore, there is one described in Japanese Utility Model Laid-Open No. 51-9966 as a hair brush intended to eliminate these drawbacks (see Patent Document 1). In this background art, three rows of bristles are provided on the hair brush body, and a blade with the blade tip 76a facing away from the bristles is provided on the hair brush body. The height of the blade 76 is provided lower than the bristle.
Japanese Utility Model Publication No. 51-9966

  In the background art described in Patent Document 1, since the blade 76 having a height lower than the height of the bristle is provided, the cutting function of the hair, Although it is imagined that it has a whispering function and a scalp massage function, it still has the following problems. This background art blade 76 is erected on the hair brush body parallel to the bristles. Therefore, during use, the blade edge 76a of the blade 76 is oriented in a direction perpendicular to the hair H (see FIG. 5).

  Thus, it is expected that the hair combing operation and scalp massage can be performed by bristle, and the hair H can be cut by the blade 76, but the cutting edge 76a of the blade 76 moves in a direction perpendicular to the hair H. Therefore, the hair is cut excessively beyond the desired cut amount of hair, and a phenomenon occurs in which the hair is cut stepwise as shown in FIG. As a result, a so-called “tiger cutting” state is exhibited, and there is a decisive problem that irregularities are generated in the hair.

  The object of the present invention is to solve the problems of the above-described background art configuration, and in addition to combing hair and performing scalp massage, It is an object of the present invention to provide a replacement razor for use in a hair brush or the like that can cut hair without requiring any skill or knack to adjust the inclination angle of a bristle or blade. Another object of the present invention is to provide a replacement razor for use in a hair brush or the like that is excellent in safety and does not possibly cause damage to the scalp with a blade during use.

The means taken by the present invention to solve the above-mentioned problems is that at least two blades are erected on the blade base material, and the blade is tilted with respect to the longitudinal center line of the blade base material. A replacement razor arranged in parallel with each other at a plurality of intervals , and by combing the hair with a hair brush with the replacement razor attached to the brush body, the replacement razor is removed from the root of the hair. The hair is cut by the blade edge while being distributed between the blade edge and the base material for blades or the bristle erected on the brush body facing the blade edge .

  In addition, the inclination angle of the blade is in the range of 10 to 80 degrees with respect to the longitudinal center line of the blade base material.

  In addition, the inclination angle of the blade is 60 degrees with respect to the longitudinal center line of the blade base material.

The term “brissle” in this specification is raised on the hairdressing tool body or replacement razor , and is called variously such as brush teeth, comb teeth, brush hair, comb teeth, etc. It is a common thing. In general, the pin is in the shape of an elongate pin, but the cross-sectional shape is not limited to a circular shape or an angular shape as long as the shape is not angular. Needless to say, the bristle includes a bunch of animal hairs such as pig hair bundled in a circular cross section.

  Since the replacement razor of the present invention is detachable from the hairdressing tool body, the replacement razor can be replaced according to deterioration due to the use of the blade.

  Moreover, since the base material for the blade of the replacement razor can be mounted in the fitting hole of the brush body, and the replacement razor can be removed from the fitting hole, the attachment / detachment mechanism of the replacement razor can be made without complicating it. Can be simplified.

  The replacement razor of the present invention will be described in detail. In the replacement razor 20, the bristle 12 is erected on the cutting tool base material 22, a cutting tool 18 having a cutting edge 18 a is erected on the side of the bristle 12, and the cutting edge 18 a of the cutting tool 18 faces the bristle 12. (See FIG. 1). In this embodiment, five bristles 12 and five blades 18 are provided, but the number thereof can be freely provided as necessary.

  Since the replacement razor 20 is detachably provided in the fitting hole 24 formed in the brush body 14, the blade base material 22 is provided corresponding to the form of the fitting hole 24. (See FIG. 2).

  More specifically, one side of the base material 22 is formed as a wavy uneven surface 26, while one side of the fitting hole 24 of the brush body 14 is a wavy uneven surface on one side of the base material 22. 26 is formed as a corrugated uneven surface 28 corresponding to H. 26 (see FIG. 1).

  Further, stoppers 30 and 30 are formed on both sides of the blade base material 22 in the longitudinal direction. On the other hand, engagement step portions 32 corresponding to the stoppers 30 are formed on both sides of the opening of the fitting hole 24 on the front surface side of the brush body 14 (see FIG. 4).

  Thus, the blade 18 side of the replacement razor 20 is directed from the surface of the brush body 14 to the lower surface, and the base material 22 of the replacement razor 20 is fitted into the fitting hole 24 of the brush body 14. Then, the wavy uneven surface 26 of the base material 22 is fitted to the wavy uneven surface 28 of the fitting hole 24 of the brush body 14, and further, a stopper 30 provided on the blade base material 22 of the replacement razor 20. , 30 are supported by the engagement step portion 32 of the brush body 14, so that the replacement razor 20 can be securely attached to the brush body 14 without being reluctant, and the replacement razor 20 is prepared for removal. A knob 34 is provided on the base material 22 (see FIG. 4).

  Thus, in the hair brush 10 in which a large number of bristles 12 are raised from the brush body 14 by fitting the base material 22 for the blade of the replacement razor 20 into the fitting hole 24 of the brush body 14, A blade 18 provided with a blade edge 18a is erected next to the bristles 12, and a hair brush 10 in which the blade edge 18a of the blade 18 faces the bristle 12 can be obtained (see FIG. 3).

  Since the replacement razor 20 is a combination of the bristle 12 and the blade 18, it has an advantage that it can be used independently as a hair styling tool independently of the brush body 14.

On the other hand, in the replacement razor 20, the bristle 12 and the blade 18 are combined. However, the inventor also plans a hair brush replacement blade that omits the bristle 12.
Although illustration is omitted, a replacement blade can be obtained by standing the above-described blade 18 on the blade base material 22 independently. In other words, referring to FIG. 1, there is no bristle 12. In this case, since the bristle 12 is not provided, a cutting hole may be mounted in the fitting hole by providing a fitting hole beside the bristle 12 of the brush body 14.

  In the hair brush 10 in which a large number of bristles 12 are raised from the brush body 14 by fitting the blade base material 22 of the replacement razor 20 without the bristles into the fitting holes of the brush body 14. The blade 8 provided with the blade edge 18 a is raised beside the bristle 12, and the hair brush 10 with the blade edge 18 a of the blade 18 facing the bridge 12 can be obtained. In this case, it is preferable to arrange the blade edge on the adjacent bristle 12 when the blade is mounted.

  Further, the blade 18 standing on the replacement razor 20 may be a plate-like one provided with a blade edge 18a on one side like a razor, provided with a plastic cover 18b having a substantially U-shaped cross section, Inside the cover 18b, the blade edge 18a is exposed to the opening side of the cover 18b and is internally provided. In order to house the blade 18 in the plastic cover 18b having a U-shaped cross section, it can be easily carried out by so-called insert molding.

  When the height of the cutting edge 18a of the cutting tool 18 is set to the same level as the height of the bristle 12, details will be described later. However, when the cutting edge 18a of the cutting tool 18 is brought into contact with the scalp T, the scalp T is damaged in use. Therefore, there is an advantage that damage to the scalp T can be prevented by adopting the above-described plastics cover 18b and covering the tip of the blade 18 with the plastics cover 18b.

  As shown in FIG. 1, the cover 18b of the blade 18 is provided with projections 18c that protrude slightly beyond the extension line of the blade edge 18a at regular intervals in a direction perpendicular to the extension line of the blade edge 18a of the blade 18. The inventor is also planning. In addition to being able to increase the strength of the cover 18b, the hair H introduced between the blade 18 and the bristle 12 can be divided by the projection 18c by providing the projections 18c at regular intervals. There is no risk of cutting excessively.

  The angle with respect to the hair H at the time of use of the hair brush 10 to which the replacement razor is attached is often different depending on the user's preference, the combing part of the hair H and the part to be cut. Furthermore, the angle with respect to the hair H also differs depending on the difference in the dominant arm. The difference in the use angle with respect to the hair H when using the hair brush 10 naturally affects the inclination angle of the bristles 12 and particularly the cutting edge 18a of the blade 18.

  Therefore, the inventor tried to study the use angle experimentally in consideration of the difference in the use conditions. As a result, for example, based on the case where the dominant arm is right-handed, the hair H of the right occipital region is moved from the right side toward the neck, the hair brush 10 is moved diagonally, and the hair H is combed and cut. In this case, it has been found that the inclination angle is suitably in the range of 10 to 80 degrees, preferably 60 degrees, with respect to the center line of the brush body 14. On the other hand, when the dominant hand is left-handed and the hair H on the left occipital region is combed and cut, the inclination angle is 100 to 170 with respect to the center line of the brush body 12 symmetrically to the above. A range of degrees has been found to be appropriate, preferably 120 degrees.

  Next, a method of using the hair brush 10 equipped with the replacement razor of the present invention will be described with reference to the drawings.

  The bristle 12 side of the brush 10 is moved toward the hair H side and along the scalp T (in the Y direction in FIGS. 6 and 7). In this case, generally, the movement usually draws a gentle arc. Accompanying this movement, the hair H can be combed by a large number of bristles 12 and blades 18 as well as the scalp T side, in other words, the excess hair H existing in the lower layer of the hair H, for example, aesthetically wasteful hair. It introduce | transduces in the space | interval between the bristle 12 and the blade edge | tip 18a of the blade 18 of the side in the convergence state.

  In this case, the converged hair H group to be introduced is forcibly introduced in a state of being crossed with respect to the vertical direction of the blade edge 18a of the blade 18, and a part of the hair H group near the blade edge 18a is introduced to the blade edge 18a. Contact. Further, by moving the brush 10 toward the distal end of the hair H (the neck side of the human body), the hair H is rubbed against the blade edge 18a, and a portion of the converged hair H, that is, the hair positioned closer to the blade edge 18a. Group H is cut. Therefore, the present invention has an advantage that the hair H can be cut together from the position near the scalp T, which is difficult to perform by itself, in other words, from the root. The cut hair H is released from the converged state and falls off, but the hair H that is generally positioned on the neck side of the human body, that is, the lower side following the movement of the brush 10 is newly added to the bristle 12 and It is introduced to be forced between the blades 18. On the other hand, the hair H in an uncut state near the blade edge 18a contacts the blade edge 18a as described above and is subsequently cut.

  Therefore, since the bristle 12 and the cutting edge 18a of the blade 18 on the side of the scalp T, that is, the underlying hair H can be brought into contact with each other, the hair H on the scalp T side can also be cut while combing with the bristle 12.
