DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush, such as a curl brush, used for curling and setting hair.

[0002]

2. Description of the Related Art In general, a curl brush for curling and setting hair has a cylindrical roll portion 42 attached to the tip of a grip portion 40, as shown in FIG. A large number of bristles 41 are planted in the area. When curling the hair using this curl brush, the hair is wound around the bristle 41 by rotating the roll portion 42 by rotating the grip portion 40 with fingers, and in this state, the hair is heated with hot air from a dryer. Setting is performed. After the setting, the hair is rewound and the curl brush is removed while rotating in the reverse direction.

However, in the curl brush described above,
Since the bristles 41 are fixed to the outer peripheral surface of the roll portion 42, when the curl brush is removed after setting the hair, the roll portion 42 is reversely rotated to remove the curl brush, particularly in the case of a woman with long hair. This work must be unwound as much as the hair has been wound around 41, which is complicated. In addition, when the curl brush is removed, the curl state may be lost or the curled hair may become bristle 41
The inconvenience that the entanglement does not come off.

Therefore, a curl brush disclosed in Japanese Utility Model Laid-Open Publication No. 4-36829 has been proposed as a curl brush for solving the above problem. This is, as shown in FIGS.
The rear side is formed on the grip portion 43a, and the front side is the brush base 43b.
A large number of small holes 48 are distributed and formed in the upper wall of the brush base 43b of the hollow rod-shaped casing 43 formed in the hollow base 43, and brushes are provided in the internal space of the brush base 43b at positions corresponding to the small holes 48. A brush bristle holder 44 having bristles (corresponding to the bristle 41 of the above-described conventional example) 50 is provided so as to be vertically movable, and the brush bristle holder 44 is provided.
A spring member 46 for pushing up and urging the brush member upward is provided, and the brush bristles 50 protrude from the small holes 48 in a state where the spring member 46 is extended, and the brush bristles in a contracted state. The tip of 50 is immersed in each small hole 48. In addition, a lifting portion 45 is rotatably supported by a support portion 47 provided at the center of the internal space of the casing 43, and a pin 45 provided at the front end of the lifting portion 45 is provided.
a is rotatably connected to a hole (not shown) provided at a lower portion of the brush bristle holder 44, and a rear end portion thereof projects from a notch hole 43c formed in a lower wall of the casing 43. It is formed on the operation unit 45b. Thereby, at normal times, the spring material 46 is extended so that the brush bristles 50 project from the small holes 48 of the brush base 43b. When the operating portion 45b is pressed, the front end of the lifting arm 45 pivots downward, whereby the brush bristle holder 44 descends against the spring force of the spring material 46 and the brush bristles 50 move. Is immersed in each small hole 48 of the casing 43. When curling the hair using such a curl brush, first grasp the grip portion 43a with one hand, and lock the vicinity of the tip of the hair with the brush hair 50 projecting from each small hole 48 of the brush base 43a. In this state, the entire brush is rotated in the circumferential direction, and the hair is brushed on the brush base 43a.
The hair is then set by applying hot air from a drier. After the setting is completed, the operation portion 45b is pressed with a thumb or a forefinger to house the brush bristles 50 in the casing 43, and the curl brush can be removed from the hair by pulling out the curl brush to the side as it is. Done.

[0005]

However, in the curl brush as described above, the operating portion 45b for moving the brush hairs 50 in and out protrudes only from the lower wall of the grip portion 43a, so that the operating portion 45b is pressed. When operating,
The thumb or the forefinger must be re-gripped so that it can be moved downward, or the grip portion 45a must be gripped in advance so that the thumb or the forefinger is directed downward, which is inconvenient. There is a problem. In addition, when the pressing of the operating portion 45b is released, the brush bristles 50 protrude due to the restoring force of the spring member 46. Therefore, when the curl brush is pulled out sideways after the setting is completed, the operating portion 45b
Must be kept pressed, the operation is complicated, and if the pressure is slightly loosened, the brush bristles 50 protrude, the hairs are caught, and the brush cannot be removed smoothly.

The present invention has been made in view of such circumstances, and has as its object to provide a brush capable of storing brush bristles in a main body by a simple operation.

[0007]

In order to achieve the above object, a brush according to the present invention comprises a grip having a hollow end and a hollow portion at the tip of the grip. A rod portion freely disposed, a cylindrical slide operation portion slidably fitted to the distal end of the grip portion, and a rod-shaped brush bristle holder integrally extending forward from the distal end of the rod portion. Part, a large number of bristles held in the bristle holding portion, and a state in which the tip of the bristle is projected from the outer circumferential portion of the bristle holding portion by the rotation of the bristle holding portion, and immersed in the outer circumferential portion. Switching means for switching to a state, a spiral guide hole is provided in the outer peripheral portion of the rod-shaped portion,
A linear elongated hole extending in the front-rear direction is provided at a tip portion of the grip portion corresponding to the guide hole, and a guide for the rod-shaped portion is formed from the inner peripheral surface of the slide operation portion through the elongated hole of the grip portion. The protrusion is slidably engaged with the hole, and the rod-shaped portion is rotated by moving the slide operation portion in the front-rear direction.

[0008]

In other words, the brush of the present invention has a grip portion having a hollow end portion, a rod portion rotatably disposed in the hollow portion of the grip end portion, and the grip portion. A cylindrical slide operating portion slidably fitted to the tip of the rod, a rod-shaped brush bristle holder integrally extending forward from the tip of the rod, and a number of brush bristle holders held by the brush bristle holder And a switching means for switching between a state in which the tip of the brush bristles protrudes from the outer periphery of the bristles holding part and a state in which the ends are immersed in the outer periphery by the rotation of the bristle holding part. A spiral guide hole is provided on the outer peripheral portion of the rod-shaped portion, and a linear elongated hole extending in the front-rear direction is provided at a tip portion of the grip portion corresponding to the guide hole. From the peripheral surface, a projection that slidably engages with the guide hole of the rod-shaped portion extends through the elongated hole of the grip portion, and thereby the rod-shaped portion is moved by moving the slide operation portion in the front-rear direction. It can be rotated. With this rotation, the state is switched between a state in which the brush bristles protrude from the outer peripheral portion of the brush bristle holding portion and a state in which the bristles enter the outer peripheral portion. Therefore, after curling the hair with the brush hair protruding and setting it with a dryer, slide the slide operation unit to immerse the brush hair, and in this state, remove the brush by pulling the brush sideways from the hair. The removal does not break the curl state, and the removal operation is simple and quick. In addition, since the slide operation section is formed in a cylindrical body to which the distal end of the grip section is fitted, and is provided on the entire outer circumferential portion of the grip section in the circumferential direction, the thumb is operated when the slide operation section is operated. Can be operated by touching the slide operation unit at any position, which is convenient. Furthermore, the state in which the brush bristles are protruded and immersed can be maintained without holding the slide operation unit with fingers, so that when the brush is pulled out to the side after the setting is completed, the slide operation unit is always operated. It does not need to be performed, the operation is not troublesome, and the hair is not cut or hurt by the brush hair.

In the present invention, the brush bristle is formed of a bristle extending in a comb-like shape from the linear connecting portion in the same direction.
In the front-rear direction, a lateral groove capable of rotatably immersing the linear connecting portion is formed, and a number of longitudinal grooves extending continuously from the lateral groove in the circumferential direction and capable of loosely fitting the bristle are formed. Further, the switching means comprises a tubular body capable of externally fitting the bristle holder in a state where the linear connecting portion is immersed in the lateral groove and the bristle is immersed in the vertical groove, In the case where a hole is formed in a portion of the cylindrical body corresponding to the front end of the cylindrical body, and the rear end of the cylindrical body is fixed to the front end of the grip portion in a detent shape, the brush bristle holding portion As a result, the bristle jumps out of the cylindrical body through the hole of the cylindrical body, and the linear connecting portion rotates while approaching the hole, whereby the bristle comes upright. In this device, a horizontal groove and a vertical groove are provided on the outer peripheral portion of the brush bristle holder, and a linear connecting portion immersed in the horizontal groove and a bristle immersed in the vertical groove are fitted to each other with a cylindrical body. Therefore, unlike the conventional example, there is no need to provide a space in the casing 43 in which the brush bristle holder 44 can be moved up and down, and the entire brush can be reduced in size. Moreover, in the brush of the present invention, a plurality of horizontal grooves (a series of vertical grooves are formed in the horizontal groove) at equal intervals are formed on the outer peripheral portion of the brush bristle holder.
The rows of bristles can also be projected at equal intervals in the circumferential direction from the outer peripheral portion of the cylindrical body. further,
In the brush of the present invention, when the cylindrical body is formed of metal, when setting by heating with a dryer, not only the hot air of the dryer is directly transmitted to the hair, but also the cylindrical body is heated by the hot air and curled. Since the hair in the state is heated simultaneously from inside and outside, there is an advantage that the setting time is shortened.

Next, the present invention will be described in detail based on embodiments.

The state in which the bristle 6 protrudes and is stored is maintained without applying any force to the slide operation unit 11 after the slide operation unit 11 is moved to a predetermined position. The same applies to a state intermediate to the housed state (see FIG. 11). Further, as shown in FIG. 13, the linear connecting portion 5 is rotatably loosely fitted in the lateral groove 4 and the inner diameter of the small hole 12a is formed slightly larger than the outer diameter of the bristle 6, so that the bristle 6 6 is a small hole 12 of the cylindrical body 12
While slightly protruding from "a", it is slightly rotated in the circumferential direction.

When the hair is set in a curled state using the brush assembled as described above, first, the gripper 10 is grasped with fingers and the slide operation unit 1 is thumbed.
1 is moved to the frontmost position to cause the bristles 6 to protrude from the small holes 12a of the cylindrical body 12 (this state is maintained even when the finger is released from the slide operation unit 11). Next, the bristle 6 locks the vicinity of the tip of the hair, and the entire brush is rotated in the circumferential direction to wind the hair around the cylindrical body 12. At this time, the tension of the forcibly pulled hair is alleviated by rotating with the bristles 6 protruding. In this state, setting is performed by blowing hot air from a dryer. The hot air of the dryer directly acts on the hair and also heats the metal cylinder 12, and the curled hair is simultaneously heated from the outside and the inside. Next, in this state, the slide operation unit 11 is moved rearward with the thumb to accommodate the bristle 6 in the cylindrical body 12, and the brush is pulled out to the side while the curled state of the hair is maintained.

As described above, in the brush, the state in which the bristle 6 protrudes from the small hole 12a of the cylindrical body 12 and the state in which the bristle 6 is accommodated in the cylindrical body 12 are switched by moving the slide operation unit 11 in the front-rear direction. be able to. Therefore, after the hair is curled with the bristles 6 protruding and set with a drier, the slide operation unit 11 can be slid and the bristles 6 can be accommodated in the cylindrical body 12. It does not break the curl state when removed from In addition, since it is not necessary to rewind the brush when removing the brush from the hair, the operation is not troublesome. In addition, the hair loss is not entangled with the bristle 6, which is sanitary. In addition, the state in which the bristles 6 protrude and the state in which the bristles 6 are immersed can be maintained without holding the slide operation unit 11 with fingers, so that the operation is not troublesome. Further, since the slide operation section 11 is formed in a tubular shape and is provided over the entire outer peripheral portion of the grip section 10, the brush is rotated to wind the hair around the brush, and then the bristle 6 is housed. It is not necessary to search the slide operation unit 11 with a finger or to re-grip the brush when operating the slide operation unit 11 for the purpose, so that the usability is good.

In the above brush, the bristle row 9
Are in the lying state, the lateral groove 4 and the longitudinal groove 3 of the bristle holding portion 2
The brush itself is compact because it is immersed in the cylindrical body 12 and is immersed in the cylindrical body 12. In addition, since the bristle 6 in a radially protruding state can be slightly rotated in the circumferential direction by loosely fitting the linear connecting portion 5 into the lateral groove 4, it is necessary to wind the hair around the brush. The hair is not pulled or cut or hurt as described above. Furthermore, because the cylindrical body 12 is formed of metal, when the hair is wound around a brush and set by heating with a dryer, not only the hot air of the dryer is directly transmitted to the hair, but also the cylindrical body is heated by the hot air, Since the curled hair is heated simultaneously from inside and outside, there is an advantage that the setting time is shortened. In addition, since the bristle 6 is projected radially from the cylindrical body 12, it is not necessary to determine the direction of the brush when locking the hair to the bristle 6, so that the usability is good.

[0025]

As described above, according to the brush of the present invention, it is possible to remove the brush by sliding the slide operation section so that the brush hair is immersed, and in this state, pulling the brush from the hair to the side. This removal does not break the curl state, and the removal operation is simple and quick. In addition, since the slide operation section is formed in a cylindrical body to which the distal end of the grip section is fitted, and is provided on the entire outer circumferential portion of the grip section in the circumferential direction, the thumb is operated when the slide operation section is operated. Can be operated by touching the slide operation unit at any position, which is convenient. further,
