Description

  The present invention relates to a hair stopper that sandwiches hair, and mainly to a hair stopper that is used to temporarily sandwich and temporarily fix hair during hair setting or makeup.

  As a conventional hair stopper, the one shown in FIG. 6 is known. This hair stopper (P) has a pair of clamping pieces (1) and (2) having opening / closing operation parts (10) and (20) at the base end at one end in the length direction, and both clamping pieces (1) ( A pair of bearing projecting pieces (12) and (22) projecting toward the corresponding sandwiching pieces (2) and (1) are provided on the inner surface on the base end side in the intermediate part of 2). In a state where the pieces (12) and (22) are combined, they are rotatably connected by the pivot shaft (5), and both sandwiching pieces (1) and (2) are wound by the winding spring (6) wound around the pivot shaft (5). ) Is biased in the direction in which the sandwiched portions (11) and (21) side of the tip end portions are closed.

  In this hair stopper (P), when the opening / closing operation part (10) (20) is picked up and closed, the closing of the tip clamping part (11) (21) is released, and both clamping pieces (1) ) (2) sandwiching portions (11) (21) are configured to expand against the urging force of the spring (6).

  By the way, such a hair stopper may be used when perming hair. However, the operation unit (10) (20) may be used with a finger wet with a cold perm solution or a finger with protective gloves. If you try to spread the pinching part (11) (21) by pinching, the operating part (10) (20) will slip and fall from your fingers, and you can operate the hair stopper (P) as you think There were cases where it was difficult to do.

  In particular, barbers and beauty salons sometimes use a large amount of hair stoppers in a short time, but it takes time and effort to remove the hair stoppers that have slipped from the hand. It was unpopular because it could not be used without washing.

  Therefore, hair stoppers in which an anti-slip measure is taken in the operation unit are known (Patent Documents 1 and 2).

  The hair stopper described in Patent Document 1 is provided with a through hole (4) in one of the portions corresponding to the operation portion, and has an arc-shaped protrusion (3) in a manner of surrounding the through hole about half on a concentric circle with the through hole. By providing, when the finger is pressed against the portion, the flesh of the finger is bitten into the through-hole, and the anti-slip effect is exhibited by hooking the finger pad to the arc-shaped protrusion.

The hair stopper described in Patent Literature 2 exhibits a non-slip effect while giving a soft feeling to the operator by separately attaching a resin member made of a material that is relatively non-slipable to a portion corresponding to the operation portion.

  However, in the conventional hair stopper (P) shown in Patent Document 1, the anti-slip protrusion (3) is provided, but the radius of curvature of the protrusion (3) is about 4.5 mm. In addition, since the height is only about 0.4 mm, the finger pad and the protrusions are difficult to adjust when the operation unit is pinched with fingers.

  In this way, if the fit between the anti-slip protrusion and the finger pad is poor, the protrusion will bite into the finger pad when operating the hair stopper, resulting in unpleasant pain or the desired anti-slip effect. In some cases, the hair stopper could slip out of the hand while operating the hair stopper.

  In addition, if the user feels uncomfortable with the anti-slip protrusion, a strange force may be applied so that the relationship between the finger pad and the protrusion is completely adjusted, and conversely, sliding may be induced. there were.

  As described above, hair stoppers that are easily slipped off from the hand have been unpopular as they are not efficient and very tiring at barbers and hair salons where a large amount of the hair stoppers must be used.

  In the hair stopper described in Patent Document 2, there is no problem because the feeling of use is soft with respect to the fingers, but it is difficult to say that the anti-slip effect is still sufficient. Furthermore, hair stoppers with separate parts in the operation part not only increase the number of parts and increase the cost, but also because the anti-slip resin member deteriorates early due to cold perm liquid etc. The lifetime of was short.

  In particular, barbers and hair salons that purchase and use hair stoppers in large quantities have been unpopular in terms of the purchase price and the life span.

  An object of the present invention is to solve the above-described conventional technical problems and to provide a hair stopper that is not slippery even when operated with fingers or protective gloves wet with cold perm solution or the like.

  In order to solve the above problems, the inventors of the present application, as a result of diligent efforts, are less likely to slip and adjust to the fingers when operating the hair stopper, and are less likely to cause the user to feel uncomfortable feelings such as pain. The anti-slip structure was found and the present invention was completed.

  That is, the present invention provides the following means.

  [1] A pair of clamping pieces in which a hair clamping part is provided in a region from the distal end part to the intermediate part, and an operation part for opening and closing the clamping part is provided at the base end part, and the pair of clamping pieces In a state where they are arranged in parallel, the base end sides are rotatably connected to each other so that the pair of holding pieces can be opened and closed, and the hair holding portion is biased in the closing direction. In the hair stopper provided with the urging means, the outer surface of the end of at least one of the operation parts has a bead shape that is long in the direction intersecting the length direction of the sandwiching piece, and has an arc shape in the length direction. The anti-slip protrusion is provided, and the anti-slip protrusion has a center of curvature at the front end side of the sandwiching piece and is set in a gentle arc shape with a curvature radius in the range of 7 mm to 15 mm. Hair stopper to do.

  [2] The hair stopper according to item 1 above, wherein the maximum height of the anti-slip protrusion is 0.8 mm to 2 mm.

  [3] The hair stopper according to the preceding item 1 or 2, wherein the anti-slip protrusion is provided with a ridge line portion.

  [4] Both the holding pieces are a combination of an outer holding piece made of resin and an inner holding piece made of aluminum or other metal, and the opening / closing operation part of the inner holding piece is provided with a non-slip projection 1 Or the hair stopper of the preceding clause 3.

  [5] The hair stopper according to any one of the preceding items 1 to 4, wherein the at least one operation portion widens toward the base end, and the base end edge has an arc shape along the anti-slip protrusion.

  [6] The hair stopper according to any one of the preceding items 1 to 5, wherein one or a plurality of holes or through holes are provided in the operation portion in the vicinity of the inside of the anti-slip protrusion.

  According to the hair stopper according to the invention of [1], since it is a non-slip projection for anti-slip having a curvature radius in the range of 7 mm to 15 mm at the center in the width direction, it is a finger pad that comes into contact when pinching the operation unit. Since the non-slip protrusion fits into the bulge and curve of the lens and interferes with the finger pad over the entire protrusion, a high anti-slip effect can be obtained while reducing unpleasant pain felt by the user.

  According to the invention of [2], since the maximum height of the anti-slip protrusion is 0.8 mm to 2 mm, the protrusion sufficiently bites into the finger pad when operating the hair stopper and exhibits a high anti-slip effect. Can be made. In addition, although it sufficiently bites into the finger pad, since the anti-slip projection fits into the shape of the finger pad, it is possible to suppress giving unpleasant pain to the user.

  According to the invention of [3], the ridge line portion provided in the anti-slip protrusion can cause the ridge line portion to sharply interfere with the finger pad when operating the hair stopper, thereby obtaining a high anti-slip effect. Moreover, although the finger pad and the protrusions interfere sharply, the anti-slip protrusion fits into the shape of the finger pad, so that it is possible to suppress unpleasant pain to the user.

  According to the invention of [4], the shape of the inner clamping piece located on the scalp side is restricted in its shape such as operability, but even within that restriction, it is sufficient to suppress giving unpleasant pain to the user. An anti-slip effect can be exhibited. Moreover, design freedom can be improved compared with a metal by using an outer side clamping piece as resin.

  According to the invention of [5], since the operation portion is widened in the proximal direction, the non-slip protrusion can be provided in the operation portion longer than in the case where the operation portion is not widened. When the anti-slip protrusion becomes longer in this way, it will interfere with the finger pad longer when operating the hair stopper, so that the anti-slip effect can be enhanced and the force applied to the finger pad is dispersed and given to the user. The effect which suppresses unpleasant pain can be heightened.

  In addition, if the base edge is formed in an arc shape along the anti-slip projection, the base edge is rounded and there are no sharp corners, so that safety can be improved and the design is also interesting. It can be.

According to the invention of [6], the anti-slip protrusion bites into the finger, and the finger meat bites into the hole or the through-hole provided in the operation portion, thereby further enhancing the anti-slip effect.

  1 to 5 are views showing a hair stopper (A) according to an embodiment of the present invention. As shown in these drawings, the hair stopper (A) of this embodiment includes a pair of clamping pieces (1) and (2), a pivot (5), and a winding spring (6).

  Each of the pair of sandwiching pieces (1) and (2) is an elongated strip-like member, and is provided with an opening / closing operation part (10) (20) at the base end part, and in other words, an area excluding the base end part. Hair sandwiching portions (11) and (21) are provided in a region from the distal end portion to the intermediate portion. The sandwiching portions (11) and (21) of the both sandwiching pieces (1) and (2) have a shape that is gently warped along the head.

  Of the pair of sandwiching pieces (1) and (2), in a state where the hair stopper (A) is attached to the hair (hair), the sandwiching piece (1) located outside (hereinafter referred to as the outer sandwiching piece) is: The sandwiched piece (2) (hereinafter referred to as the inner sandwiched piece) located inside is formed of a metal plate press-molded product, and is formed of a hard or semi-hard synthetic resin integral molded product.

  The end part of the operation part (20) of the inner clamping piece (2) is widened toward the outer side, and has a sector shape in which the end edge is arcuate. A non-slip protrusion (3) having a fan-shaped shape is formed in the vicinity of the edge so as to protrude outward. The anti-slip projection (3) has a radius of curvature at the center in the width direction of 8 mm (a in FIG. 4), a radius of curvature at the inner end of 7 mm (b in FIG. 4), and a radius of curvature at the outer end of 9 mm (see FIG. 4). 4 c). In the present specification and claims, the term “radius of curvature” simply indicates the radius of curvature of the central portion in the width direction of the protrusion (3).

  The radius of curvature of the central portion in the radial direction of the protrusion (3) is preferably 7 mm to 15 mm. This is because the range is a range that closely follows the finger pad of the thumb or index finger when operating the hair stopper (A). If the radius of curvature is less than 7 mm, the user feels uncomfortable, for example, both ends of the protrusion (3) may be stuck in the finger pad, and the contact part with the finger pad is reduced, reducing the anti-slip effect. End up. On the other hand, if it is larger than 15 mm, the familiarity with the finger pad is deteriorated and the contact portion is reduced, so that the slip prevention function is inferior. The curvature radius of the anti-slip protrusion (3) is preferably in the range of 7.5 mm to 10 mm.

  The cross-sectional shape in the radial direction of the protrusion (3) is a substantially isosceles triangle as shown in FIG. Therefore, the anti-slip protrusion (3) has slopes on both sides facing the center of curvature and outward, and the apex of the cross-sectional triangle forms the ridge line portion (30).

  The ridge line portion (30) is the maximum height portion of the protrusion (3), and the height is 1.1 mm from the outer surface of the sandwiching piece (2).

  The maximum height of the protrusion (3) is desirably 0.8 mm to 2 mm. If the protrusion amount is less than 0.8 mm, the interference state with the finger pad is deteriorated and the slip prevention function is inferior. On the other hand, if it is larger than 2 mm, it will bite into the finger pad and the user will feel uncomfortable when operating the hair stopper (A). The maximum height is preferably in the range of 1 mm to 1.5 mm.

  In addition, when the projection (3) has a slope as described above, the slope is along the finger pad, so that it can interfere with the finger pad in a planar shape, so that unpleasant pain for the user can be eased. In addition, if the ridge line portion (31) is present, the anti-slip effect can be improved by sharply interfering with the finger pad. And the anti-slip | skid effect can be improved, without giving an unpleasant pain to a user by cooperating these slopes and a ridgeline part (31).

  The anti-slip protrusion (3) is integrally formed at the same time when the inner clamping piece (2) is press-formed from a metal plate.

  A through hole (4) penetrating circularly from the outer surface to the inner surface of the operation portion (20) is provided in the vicinity of the inside of the anti-slip protrusion (3). The through hole (4) is not concentric with the anti-slip protrusion (3), and is positioned closer to the anti-slip protrusion (3) from the center of curvature of the anti-slip protrusion (3). The center of curvature of the anti-slip protrusion (3) and the center of the through hole (4) are located on the center line in the width direction of the inner clamping piece (2).

  In the present embodiment, the anti-slip protrusion (3) and the through hole (4) are provided on the inner operation portion (20). The inner holding piece (2) located on the scalp side is greatly warped outward. This is because there are morphological restrictions such as inability to prevent slipping, and the anti-slip effect is exhibited within these restrictions.

  On the other hand, the operation part (10) of the outer clamping piece (1) has a shape that warps outward so that its base end part is separated from the inner clamping piece (2). The outer operation portion (10) is configured to exhibit an anti-slip effect by the curve along the shape of the finger pad contacting the operation portion (10).

  In addition, it is arbitrary to provide the curved projections and through holes in the outer operation portion (10). In addition, grooves and character designs that also take design into consideration may be provided in three dimensions.

  The inner clamping piece (2) is provided on both side edges on the base end side, specifically, on both side edges between the clamping part (21) and the operation part (20). A pair of bearing projecting pieces (22) and (22) projecting upward toward) are integrally formed. A shaft insertion hole (23) (23) is formed in the center of each of the pair of bearing protrusions (22) (22).

  The outer clamping piece (1) is formed on the both side edges on the base end side, specifically on the both side edges between the clamping part (11) and the operation part (10). A pair of bearing projecting pieces (12) and (12) projecting downward toward the bottom are integrally formed. A shaft insertion hole (13) (13) is formed in the center of each of the pair of bearing protrusions (12) (12).

  Moreover, the slit (14) is continuously formed in the clamping part (11) of an outer side clamping piece (1) along the length direction.

  And it respond | corresponds in the aspect which each bearing projection piece (12) (12) of an outer side clamping piece (1) is located in the width direction outer side of each bearing projection piece (22) (22) of an inner side clamping piece (2). It arrange | positions so that a bearing protrusion piece (12) (22) may follow. Further, the pivot shaft (5) is rotatably mounted in the shaft insertion holes (13) and (23) of the bearing projecting pieces (12) and (22). Thereby, a pair of clamping piece (1) (2) is connected so that opening and closing is possible centering on a pivot (5), and corresponding clamping part (11) (21) is comprised so that attachment or detachment is possible.

  A winding spring (6) is wound around the pivot (5) as an urging means. The both ends extending portion of the coil spring (6) is disposed in contact with the back surfaces of the operation portions (10) and (20) of the sandwiching pieces (1) and (2). The pair of clamping pieces (1) and (2) are urged by the urging force of the winding spring (6) so that the clamping portions (11) and (21) are always closed. In the present invention, the biasing means discloses the coil spring (6), but it may be simply a leaf spring. The material can also be selected from metals, resins, and the like.

  As for the said hair stopper (A), the state by which both clamping part (11) (21) was closed by the urging | biasing force of the winding spring (6) is a normal state. And if both operation parts (10) and (20) are pinched with a thumb and an index finger and it closes, the clamping part (11) (21) will expand against the urging | biasing force of a winding spring (6).

  At this time, the thumb or forefinger of the index finger is arranged on the inner operation section (20). The anti-slip protrusion (3) provided on the inner operation part (20) bites into the finger pad to some extent while following the curve of the finger pad, and the ridge line part (30) interferes with the finger pad surface. Furthermore, the meat of the finger pad bites into the through hole (4) provided inside the anti-slip projection (3) of the operation unit (20). These anti-slip protrusions (3), their ridges (30), and the through holes (4) provide an anti-slip effect, and the user can use the anti-slip protrusion (3) according to the curvature and radial cross-sectional shape. Can alleviate giving unpleasant pain. This is true even for users wearing gloves to protect their fingers from cold perm solution.

  Of the sandwiched portions (11) and (21) expanded as described above, the inner sandwiched portion (21) is inserted into the scalp side of the hair whose shape is adjusted. When the force applied to the operation portions (10) and (20) is released, the pinching portions (11) and (21) are urged in the pinching direction by the winding spring (6) to pinch the hair.

  Thus, the hair whose shape is adjusted can be maintained as it is.

  The present invention provides a hair stopper that can be used for hair setting at home as well as a hair stopper that is used for business purposes in a barber or beauty salon.
