Description

Cutting blade for exchange of hairbrush and hairbrush {HAIR BRUSH AND REPLACEABLE CUTTING UNIT FOR HAIR BRUSH}

The present invention relates to a hairbrush having a hair cutting function, a hair combing function, and a scalp massage function, and a cutting blade for exchanging a hair brush used in the hair brush.

In order to achieve the beauty of the hair, it is widely used to adjust the style of the hair while combing the hair, partially cutting the excess hair, and performing a scalp massage.

In these operations, independent haircutting scissors and combs were used according to the purpose, and combing and cutting of hair were traditionally performed.

It is also known that a hair brush is employed for the purpose of performing scalp massage along with adjusting the hair.

However, the above-described background art requires the use of a hair brush in addition to the barber scissors and the comb, and the work requires skill or so-called tricks, and thus has a drawback in that it is inconvenient to use.

Thus, there is one described in Japanese Utility Model Publication No. 51-9966 (see Patent Document 1) as a hair brush 70 intended to solve these drawbacks.

This background art is provided with three rows of bristle 74 in the hair brush body 72, and the blade tip 76a is directed toward the opposite side to the hair brush body 72 between the bristle 74. The cutting blade 76 is provided in the hair brush body 72, and the height of the cutting blade 76 is set lower than the bristle 74 (see Figs. 12 and 13).

(Patent Document 1)

Japanese Utility Model Publication No. 51-9966

In the background art described in Patent Document 1, since the cutting blade 76 having a lower height than the height of the bristle 74 is provided, the cutting blade 76 does not damage the scalp at first glance. It is imagined to have a hair cutting function, a hair combing function and a scalp massage function, but still have the following problems.

As shown in FIG. 13, the cutting blade 76 of this background art is erected to the hairbrush main body 72 in parallel with the bristle 74. As shown in FIG.

Therefore, in use, the cutting edge 76a of the cutting blade 76 is directed at right angles to the hair H (see Fig. 14).

In this way, hair combing and scalp massage can be expected to be performed by the bristle 74, and the hair H can be cut by the cutting blade 76, but the cutting edge of the cutting blade 76 can be expected. Since 76a moves in a direction perpendicular to the hair H, it cuts excessively in excess of the desired cut amount of hair, so that the phenomenon that the hair is cut in steps occurs as shown in FIG.

As a result, there is a decisive problem that it is in a state of a so-called "straightened hair" and that a layer is generated on the hair.

An object of the present invention is to solve the problems of the above-described configuration, and in addition to combing hair or performing scalp massage by one operation, the angle of inclination of the bristle or cutting blade with respect to the scalp, in particular. It is to provide a hairbrush that can cut hair without requiring any skill or skill to adjust the hair.

Another object is to provide an excellent safety hairbrush with the possibility of damaging the scalp by the cutting blade in use.

The following also enumerates the object of the present invention.

The present invention provides a hairbrush in which hair is not cut when the hair is cut.

Providing a hairbrush that can replace the cutting blades due to deterioration due to the use of cutting blades, providing a hairbrush that can double the amount of hair cut, and smoothly introducing hair between the cutting blades and bristle. It is in the provision of the hairbrush which can make it.

The invention of the hairbrush 10 and the cutting blade 20 for exchanging a hairbrush which concerns on embodiment of this invention is demonstrated with reference to drawings.

The present invention is a combination of a well-known hair brush and a cutting blade for cutting hair, so that it is possible to cut excess hair while combing the hair.

The hair brush 10 of Example 1 is demonstrated.

In this embodiment, (1) the hairbrush 10 in which the cutting blade 18 was fixed to the brush body 14, and (2) the hairbrush provided with the bristle 12 and the cutting blade 18 were replaced. The hairbrush 10 detachably attached to the brush body 14 and the cutting blade 20 for replacement of the hairbrush provided with only the cutting blade can be detachably attached to the brush body 14. It is mentioned with respect to the hairbrush 10 is installed.

The basic configuration of the hair brush 10 in which the cutting blades 18 are fixed to the brush body 14 is the hair brush 10 in which a plurality of bristle 12 is erected to the brush body 14. The cutting edge 18 provided with the cutting edge 18a is made upright in the vicinity of the slab 12, and the cutting edge 18a of the cutting blade 18 is arrange | positioned facing the bristle 12. As shown in FIG. (See FIG. 1, FIG. 2, FIG. 4).

The hairbrush 10 is composed of a brush body 14 having a bristle 12 and a handle 16, as known, and generally the brush body 14 is thin and long, and has a long side and a short side. Although the form is not limited.

In addition, the inventor intends that the handle 6 is absent and the brush body 14 is not thin and long.

Moreover, the handle 16 can be rotated with respect to the brush main body 14, and it does not matter whether it is non-rotation.

The change of the attachment position with respect to the main body 14 is free as known with this kind of brush (see Fig. 1).

As is known in the hair brush 10, a plurality of bristle 12 is upright on the lower surface of the brush body (14).

Although arrangement | positioning of the bristle 12 may be different from the case where the pitch space of a column direction is constant, in this invention, any may be sufficient.

The bristle 12, together with the main body 14, is preferably plastic in consideration of production efficiency and production cost, but the material is not limited. For example, as is widely known, a plurality of bristles are freely formed by a large group of these units, with one unit having a plurality of animal hairs such as piglets.

The tip of the bristle 12 (the scalp side at the time of use) is in contact with the human scalp T at the time of use, and contributes to combing the hair (H) and at the same time performing massage of the scalp (T). It is preferable that an excellent cross section is formed in an arc shape, and it can contribute to the damage of the scalp T and the pain relief (refer FIG. 1-FIG. 4).

The shape of the bristle 12 is not limited, but as is generally known, an elongated pin-shaped one having a circular cross section may be used.

In this case, there is an advantage of using an existing brush or production equipment.

On the other hand, in this invention, the plate-shaped cutting edge 18 provided with the blade tip 18a in the vicinity of the bristle 12 is erected on the lower surface of the brush body 14, and the hair H is brought into a constant convergence state. It is intended to be cut. (See Figs. 3 and 4).

In the case where the cutting blades 18 are upright in the vicinity of the bristle 12, since the cutting blades 18 are generally provided in the entire area of the brush body 14, since there is a risk of excessive cutting of the hair H, As shown in FIG. 1, it is generally sufficient by providing so as to occupy a certain area of the brush body 14.

However, for the case where the hair is cut for a large number of hairs, especially for a large number of people or for some kind of purpose, it is not necessary to necessarily restrict the installation of the cutting blade 18 to a certain area of the brush body 14.

In the case of illustration, although five cutting edges 18 are provided in the center of the brush main body 14 near the front-end | tip, the number and position are not restrict | limited in particular.

Although the cutting edge 18 was made upright in the vicinity of the bristle 12, since the cutting of the hair H introduce | transduced between the bristle 12 and the cutting edge 18 which adjoin each other is especially intended, As shown in FIG. 1, FIG. 3, and FIG. 4, it is hoped that the cutting edge 18a of the cutting blade 18 is arrange | positioned facing the adjacent bristle 12. FIG.

The structure of the cutting blade 18 should just be a plate-like thing with the blade tip 18a in one side like a razor, and the plastic cover 18b which has a substantially U-shaped cross section is provided in this cover 18b. The blade tip 18a is exposed to the opening side of the cover 18b to be incorporated.

In order to embed the cutting edge 18 in the cover 18b made of plastic having a U-shaped cross section, it can be easily carried out by performing so-called insert molding.

When the height of the cutting edge 18a of the cutting blade 18 is set to the same degree as the height of the bristle 12, the details will be described later. However, in use, the cutting edge 18a of the cutting blade 18 is scalp. Since it may damage the scalp T when it comes into contact with (T), the plastic cover 18b described above is employed, and the tip of the cutting blade 18 is covered with the plastic cover 18b. This has the advantage of preventing damage to the scalp T.

2 and 4, the cover 18b of the cutting blade 18 slightly protrudes beyond the extension line of the cutting edge 18a in a direction perpendicular to the extension of the cutting edge 18a of the cutting blade 18. The inventor also intends to form the projections 18c at regular intervals.

In addition to increasing the strength of the cover 18b, the projections 18c are formed at regular intervals so that the hair H introduced between the cutting blade 18 and the bristle 12 is formed on the projections 18c. There is no fear of excessive cutting of the hair H since it may be segmented by.

The inventor also intends to set the height of the cutting blade 18 lower than the height of the bristle 12.

Since the cutting blades 18 generally employ metal materials, in the case of the present invention, the tip side of the cutting blades 18 contacts the scalp T when the brush 10 is used. Damage must be avoided.

Thus, the inventors set the bristle 12 high and the cutting blade 18 low so that the tip side of the bristle 12 contacts the human scalp T when the brush 10 is used. The tip of the cutting blade 18 was attempted not to contact the scalp T.

Although the case where the height of the cutting blade 18 is lower than the bristle 12 is also expected, in consideration of the stability of the scalp T at the time of use, the protection to protect the scalp T appropriately at the tip of the cutting blade 18. Mounting the member is free.

Although the plate-shaped cutting edge 18 provided with the blade edge | tip 18a in the vicinity of the bristle 12 was mentioned above being made upright on the lower surface of the brush body 14, In this invention, the bristle 12 at the time of use is used. The hair H is introduced between the cutting edge 18 and the hair H is brought into contact with the cutting edge 18a to cut the hair H. Therefore, the cutting edge 18a of the cutting blade 18 ) Is facing the bristle 12.

The bristle 12 has previously been described in which a conventionally known one is erected on the lower surface of the brush body 14, but among the bristle 12, the bristle 12 is opposed to the cutting edge 18a of the cutting blade 18. As for the bristle 12, the inventor intends to employ | adopt what has a circular arc surface in a cross section like a figure, and is high compared with the bristle 12 which is different in strength.

In the present invention, the hair H is forcibly inserted into the converged state between the bristle 12 and the cutting blade 18, and the hair H in the converged state is cut by the cutting blade 18. Since the conventional hairbrush is only intended for combing the hair or scalp massage, in particular, it concentrates on the bristle 12 facing the cutting edge 18a of the cutting blade 18. Since the stress acts and the load is expected to act on the bristle 12, a cross section has an arc or a high strength compared with other bristle 12 in the cross section.

Further, by forming the bristle 12 into an arcuate surface in the cross section, there is an advantage in that the hair H introduced at the time of introduction of the hair H can be smoothly introduced.

Therefore, as for the bristle 12 which opposes the blade edge | tip 18a of the cutting blade 18, it is preferable to enlarge the cross-sectional area or employ | adopt the thing of the material excellent in intensity | strength as shown in the figure.

In addition, it is expected that a load acts on the cutting blade 18 similarly to the bristle 12, but since a metal material is generally employed, the need for attention is not particularly required. Free.

Although the cutting edge 18a of the cutting blade 18 was described above facing the bristle 12, a more preferable example is the cutting blade 18 on the extension line of the central axis of the bristle 12. It is preferable that the blade tip 18a is located.

In this way, the blade tip 18a is positioned on the extension line of the center axis of the bristle 12, so that the hair H can be cut in a state close to the above.

The inventors intend that the cutting blade 18 is fixed to the brush body 14 and installed in a detachable manner in preparation for deterioration due to use.

In addition, the specific example which detachably attaches the cutting blade 18 to the brush main body 14 is demonstrated later.

In addition, in the embodiment of the present invention, the cutting blade 18 and the bristle 12 are gradually tapered upward and upward, respectively, so that the gap between the cutting blade 18 and the bristle 12 is reduced. Since it is possible to increase the amount of hair introduced between the cutting blade 18 and the bristle 12 by being provided so as to be wider, it is intended to contribute to the cutting of a large amount of hair.

Further, the cutting edge 18 and bristle (by cutting the edge 18a side of the cutting blade 18 of the bristle 12 adjacent to the cutting blade 18 are formed so as to have an arc at least in cross section. 12) Hair H can be introduced smoothly.

The angle with respect to the hair H at the time of use of the hairbrush 10 does not differ depending on a user's preference, the combing part of the hair H, or the part to cut | disconnect.

In addition, the angle with respect to the hair (H) also differs depending on the difference of the main arm.

The difference of the use angle with respect to the hair H at the time of use of the hairbrush 10 affects the inclination angle of the said bristle 12 and especially the cutting edge 18a of the cutting edge 18.

Thus, the inventors have attempted to study the use angle experimentally in consideration of the difference in the above use conditions.

As a result, for example, the mainly used arm is a right arm, and the hair H 10 is inclined to move the hair H of the right rear head from the right side to the neck direction, and the hair H is combed and cut. Based on the case, the inclination angle was found to be 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, the inclination angle when the main arm is the left arm and the hair H of the left occipital is combed and cut is a reference to 100 to 170 symmetrically with respect to the center line of the brush body 12. It has been found that the range of the figure, preferably 120 degrees, is appropriate.

The cutting blade 18 is provided with a cover 18b made of plastic having a U-shaped cross section independent of the bristle 12, and the blade tip 18a is moved to the opening side of the cover 18b in the cover 18b. I explained that it was built by exposing it.

On the other hand, in this embodiment, although illustration is abbreviate | omitted instead of providing the cover 18b for cutting blades 18, the bristle and the cutting blades 18 which served as the protection member of the cutting blades 18 are not provided. The bristle 12 which is not made upright is erected to the brush body 14, and the cutting edge 18a of the cutting blade 18 is arranged to face the bristle 12 which is not provided with the cutting blade 18. The object of the present invention can be achieved.

In other words, it can be said that the bristle 12 itself is provided with the cutting blade 18.

This embodiment is a cutting blade for exchange of a hairbrush in which the cutting blade 18 is detachable from the brush body 14 in preparation for deterioration due to the use of the cutting blade 18 of the hairbrush 10 described above ( 20).

With respect to the hairbrush 10 in which the cutting blade 18 is attached to the brush body 14 in a non-removable state, the cutting blade 20 is replaced by the brush body 14 in the cutting blade 20 for replacement of the hairbrush. ), The cutting blade 18 and the bristle 12 are provided on the cutting blade base material 22 instead of the mounting blade. Therefore, the structure common to the above-described hairbrush 10 will be described. Use it.

Moreover, the cutting blade for exchange of the hairbrush which provided only the cutting blade in the base material 22 for cutting blades is also mentioned.

Moreover, the structure of the brush main body 14 which makes the cutting blade 20 for exchange of a hairbrush detachable is demonstrated together (refer FIG. 6-9).

As for the cutting blade 20 for hairbrush exchange, the bristle 12 is erected to the base material 22 for a cutting blade, and the cutting blade 18 provided with the blade tip 18a in the vicinity of the bristle 12 is While standing upright, the cutting edge 18a of the cutting edge 18 is arranged to face the bristle 12 (see Figs. 6 and 9).

In the present embodiment, five bristle 12 and five cutting blades 18 are provided, respectively, but the number of them is free to be installed as necessary in the case of the hairbrush 10 described above.

Since the cutting blade 20 for replacing the hair brush is detachably installed in the fitting hole 24 formed in the brush body 14, the cutting blade base material 22 corresponds to the shape of the fitting hole 24. (See Fig. 9).

More specifically, one side of the base material 22 is formed as a wave-shaped uneven surface 26, while one side of the fitting hole 24 of the brush body 14 is the base material 22. Corrugated uneven surface 26 on one side of the side is formed as a wavy uneven surface 28 (see Fig. 6).

In addition, stoppers 30 and 30 are formed on both sides in the longitudinal direction of the base material 22.

On the other hand, engaging step portions 32 corresponding to the stoppers 30 and 30 are formed on both sides of the opening of the fitting hole 24 on the surface side of the brush body 14 (see Fig. 9).

In this way, the said base material 22 of the cutting blade 20 for hairbrush replacement of the cutting blade 18 of this hairbrush exchange blade 20 toward the lower surface from the surface of the brush main body 14 is carried out. Is fitted into the fitting hole 24 of the brush body 14.

And the wavy concave-convex surface 26 of the base material 22 is fitted to the wavy concave-convex surface 28 of the fitting hole 24 of the brush body 14, and also the cutting blade for replacement of a hairbrush ( The stoppers 30 and 30 formed on the base material 22 of the 20 are supported by the coupling step 32 of the brush body 14, so that the cutting blade 20 for replacing the hairbrush is attached to the brush body 14. It can be mounted reliably without shifting, and the holding part 34 is formed in the base material 22 in preparation for isolate | separating the cutting blade 20 for exchange of a hairbrush (refer FIG. 9).

In this way, the bristle 12 of the bristle body 12 is made by fitting the base material 22 for the cutting blade 20 of the cutting blade 20 for a replacement of the hairbrush to the fitting hole 24 of the brush body 14. In the hairbrush 10, which is erected in (14), the cutting edge 8 provided with the cutting edge 18a is placed upright in the vicinity of the bristle 12, and the cutting edge of the cutting edge 18 18a) can obtain a hairbrush 10 facing the bristle 12 (see Fig. 8).

In addition, since the cutting blade 20 for exchange of the hairbrush combines the bristle 12 and the cutting blade 18, it can be used independently as the tool for organizing hair independently of the brush body 14. That has the advantage.

In addition, although the bristle 12 and the cutting blade 18 were combined with the cutting blade 20 for exchange of the said hairbrush, the inventor also plans the cutting blade for replacement of the hairbrush which omitted the bristle 12. .

Although illustration is abbreviate | omitted, the cutting blade for exchange can be obtained by standing up the said cutting blade 18 independently to the base material 22 for cutting blades.

In other words, referring to Fig. 6, the bristle 12 is not present.

In this case, since there is no bristle 12, the fitting blade may be attached to the fitting hole by forming a fitting hole in the vicinity of the bristle 12 of the brush body 14.

By fitting the base material for the cutting blade of the cutting blade for replacement of the bristle without such bristle into the fitting hole of the brush body 14, the hair brush in which the plurality of bristle 12 is erected on the brush body 14 is erected. In (10), the cutting edge (8) having the cutting edge (18a) is upright near the bristle (12), and the cutting edge (18a) of the cutting blade (18) is the bristle (12). The hair brush 10 which opposes can be obtained.

In this case, it is preferable to arrange the blade tip in the adjacent bristle 12 when the cutting blade is attached.

Next, an example of use of the hairbrush 10 according to the embodiment of the present invention will be described with reference to the drawings.

An example of this usage method is common to the three types of hair brushes 10 of (1), (2) and (3) described above.

The bristle 12 side of the brush 10 is moved toward the hair H side and along the scalp T (symbol Y direction in Fig. 3).

In this case, the movement is usually drawn with a gentle arc.

According to this movement, not only can the hair H be combed by the plurality of bristle 12 and the cutting blade 18, but also the scalp T side, that is, the example present in the lower layer of the hair H For example, excess hair (H), which becomes hair that is insignificant in appearance, is introduced into the space between the bristle 12 and the blade tip 18a of the cutting blade 18 in the vicinity thereof (FIGS. 3 and 4). Reference).

In this case, the hair H group in the converging state to be introduced is forcibly introduced in a state crossing with respect to the vertical line direction of the cutting edge 18a of the cutting blade 18, and the hair H near the cutting edge 18a. A part of the group contacts the blade tip 18a (see Fig. 4).

In addition, by moving the brush 10 in the tip direction (the neck side of the human body) of the hair H, the hair H is rubbed with the blade tip 18a, and a part of the hair H in the converged state, that is, the blade tip The hair (H) group located near (18a) is cut | disconnected (refer FIG. 4).

Therefore, the present invention has the advantage that the hair H can be collected and cut from the root part, in other words, the position near the scalp T which is very difficult to carry out by itself.

Then, the cut hair (H) is released from the converging state and removed, but in accordance with the movement of the brush 10, the hair (H), which is generally located on the neck side, i.e., the lower side of the human body, is newly cut by the bristle (12). It is introduced to be forced between the blades 18.

On the other hand, the hair H in the uncut state near the blade tip 18a is in contact with the blade tip 18a as described above and continues to be cut.

Therefore, the bristle 12 and the cutting edge 18a of the cutting blade 18 in the vicinity thereof can be brought into contact with the scalp T side, that is, the lower layer of hair H, so that the hair on the scalp T side ( H) can also be cut while combing with bristle 12.

Next, the other hair brush 50 which concerns on embodiment of this invention is demonstrated. (Refer FIG. 10, FIG. 11).

Also about this embodiment, similarly to the previous embodiment, (4) the hairbrush 50 having the cutting blade 56 fixed to the brush body 54, (5) the bristle 52 and the cutting blade 56 The cutting blade for the replacement of the hairbrush provided with the hairbrush 50 detachably attached to the brush body 54, and (6) The cutting blade for the replacement of the hairbrush provided with only the cutting blade 52 is the brush body. Reference is made to the hairbrush 50 detachably installed at 54.

In the hairbrush in which a plurality of bristle 52 are erected to the brush body 54, the bristle 52 is a constant region of the brush body 54 and is located at a position lower than the height of the bristle 52 between bristles. The cutting blade 56 is formed in the.

The blade tip 56a of the cutting blade is arranged toward the outside of the brush body 54 and is separated from the brush body 54.

More specifically, the pair of cutting blade support members 58 are erected on both sides of the brush body 54, and the cutting blades 56 are horizontally interposed between the pair of cutting blade support members 58 above. It is attached in a state.

In this case, although the blade tip 56a is formed in the both ends of the cutting blade 56, the blade tip 56a is not necessarily formed in both sides, It is free to be formed only in one side.

In general, the cutting blade 56 is sufficient to have a plate shape, but the cutting blade 56 is cut away from the brush body 54 at a predetermined distance so that the blade tip 56a is directed toward the outside of the brush body 54. have.

In addition, although the specific example of the cutting blade 56 shown is shown in the horizontal state, the inventor also plans to make a cross-sectional shape draw a mountain shape, and to form space on both sides of a cutting blade.

The structure which installs detachable cutting blade of the hairbrush provided with the bristle 52 and the cutting blade 56 in the brush body 54, and the cutting blade for replacement of the hairbrush provided only with the cutting blade 56 The configuration for detachably attaching the brush body 54 to the brush body 54 may be basically the same as the configuration of the first embodiment described above.

Next, an example will be described with reference to the drawings on how to use the hair brush 50 according to the embodiment of the present invention.

The bristle 52 side of the brush 50 is moved toward the hair H side and along the scalp (symbol Y or Z direction in Fig. 11).

In this way, the blade tip 56a of the cutting blade 56 is directed at right angles to the hair H located on the scalp side, and follows the movement of the cutting blade 56 and is located on the scalp side. The cutting blade 56 is moved at a right angle with respect to the cut), so that the cutting of the hair H is performed remarkably, and the hair H can be combed.

In this example, since the cutting blade 56 is spaced apart from the brush body 54 at a predetermined interval, the cut hair H falls somewhere in the space formed above and below the cutting blade 56 as a boundary. Therefore, the hair H is not blocked between the bristles 52.

Since the first problem solving means is constituted as described above, it has the following effects.

The bristle side of the brush is moved toward the hair side and along the scalp, and is generally moved from the top of the head to the neck.

In this case, in the comb of the background art, since the contact of the comb with the scalp is a line contact, it is necessary to keep the comb at a constant inclination angle, but the work of maintaining the inclination angle constantly requires skill or skill. And the clutter of the work could not be avoided.

However, in the present invention, since a large number of bristles are provided, there is an advantage that the bristles can be used simply by bringing the bristles into contact with the scalp, without being particularly concerned with the adjustment of the inclination angle of the bristles.

Since a large number of bristles are provided, the group of bristles of the hairbrush can be brought into surface contact only by contacting the scalp.
