Abstract

PROBLEM TO BE SOLVED: To protect the hair from damage while suppressing heat radiation from a hair curler which generates heat, in a hair clip fixedly clipping the hair so that the hair wound around the hair curler does not come loose.SOLUTION: The clipping pieces 10 of the hair clip 1 are formed in a triple structure comprising a synthetic resin-made base plate 11, a synthetic resin-made lid plate 12, and a metallic heat-insulating plate 13 each curved roughly in a semi-cylindrical shape. The base plate 11 is provided with a recess part recessed roughly in a semi-cylindrical shape along the inner peripheral face, wherein the heat insulating plate is fitted, and the lid plate 12 is further fitted from its upper part. Heat from a hair curler 2 is accumulated in the heat-insulating plate 13 incorporated into the clip pieces 10, so that heat radiation is suppressed to facilitate formation of waves and curls in the hair. The outer face of the clip pieces 10 is covered with the base plate 11 and the lid plate 12, so that the hot heat-insulating plate 13 is prevented from touching the hair. Thus, damaging of the hair and a burn by the heat of the heat-insulating plate 13 can be prevented.

Description

The present invention relates to a hair clip that is sandwiched and fixed from above so that the hair wound around the hair curler cannot be unwound.
More specifically, the present invention relates to a hair clip excellent in heat retention, which suppresses heat dissipation of a hair curler that generates heat to set hair.

  As a hair clip for sandwiching and fixing the hair wound around the cylindrical hair curler from above, a hair clip having a cylindrical shape according to the shape of the hair curler is known as in Patent Document 1. It has been.

Specifically, this type of hair clip is composed of a pair of opposed clip pieces that are curved in a substantially semi-cylindrical shape, and tabs are integrally provided at one end in the bending direction (circumferential direction) of both clip pieces. .
Further, the clip pieces are connected to each other by inserting the rotation shaft through the overlapping portion of both tabs.

As a result, the clip piece has a rotational axis between a closed position where the other ends in the circumferential direction approach each other and the entire hair clip closes in a cylindrical shape, and an open position where the other ends separate from each other and the cylinder opens. It can be rotated around the center.
Further, between the tabs, a leg portion of a torsion spring (torsion spring) that fits around the rotating shaft is stretched over, so that the clip piece is always urged toward the closed position.

When using a hair clip, the tabs of both clip pieces are pinched and rotated from the closed position to the open position against the elasticity of the torsion spring.
When this open hair clip is put on the hair curler with the hair around the outer peripheral surface and then the finger is removed from the tab, the clip piece is automatically closed by the action of the torsion spring. Therefore, the hair wound around the hair curler is fixed by being sandwiched between the hair clips.
Here, the hair curler can generate heat by incorporating a heater or the like, and the hair is curled or curled by the high heat.

Japanese Patent No. 2866594

By the way, most of the conventional hair clips of this type are ones in which each clip piece is integrally molded from a synthetic resin, and are not excellent in heat retention.
For this reason, there is a problem that the heat of the hair curler that generates heat is easily dissipated and it is difficult to attach large waves and curls to the hair.

  On the other hand, it may be possible to increase the heat retention by forming each clip piece entirely from a metal with good thermal conductivity, but in that case, the heat of the hair curler is conducted and the metal heated to directly contacts the hair. become. For this reason, the hair is damaged, and there is a risk of burns, which is not preferable.

  In addition, it may be possible to compensate for the heat dissipation of the hair curler by heating the hair clip by incorporating a heater in the clip piece, etc., but the power consumption increases compared to the case where only the hair curler generates heat. Therefore, the structure of the clip piece becomes complicated. Therefore, the consumption cost and the manufacturing cost are increased, which is not preferable.

  Accordingly, the present invention is to protect the hair from being damaged while suppressing the heat dissipation of the hair curler that generates heat, with respect to the hair clip that is fixed by being pinched from above so that the hair wound around the hair curler is not unraveled.

  In order to solve the above-described problems, each of the pair of clip pieces of the hair clip according to the invention has its outer surface made of a synthetic resin and its inside made of metal.

  More specifically, the clip piece is made of a synthetic resin substrate having a recess that is curved into a substantially semi-cylindrical shape and recessed in a substantially semi-cylindrical shape along its inner or outer circumferential surface, A metal heat insulating plate that is bent into a semi-cylindrical shape and is fitted into the recess of the substrate, and a synthetic resin lid plate that is bent into a substantially semi-cylindrical shape and closes the opening of the recess of the substrate. It was.

  The heat retaining plate built into the clip piece is made of metal and has good thermal conductivity, so heat is accumulated on this heat retaining plate to suppress the heat dissipation of the hair curler, and the hair has clean waves and curls. It becomes easy.

  At the same time, the outer surface of the clip piece is covered with a substrate made of synthetic resin with low thermal conductivity and a cover plate, so that the heat retaining plate heated by heat storage does not directly touch the hair, so that the hair becomes the heat of the heat retaining plate. Will prevent it from being damaged or burned.

  Further, since synthetic resins are generally lighter and cheaper than metal, weight reduction and cost reduction are achieved as compared with the case where the entire clip piece is formed of metal.

  Furthermore, since the clip piece only accumulates the heat of the hair curler and does not generate heat, the power consumption does not increase, and the structure is not complicated by incorporating a heater, the consumption cost and Manufacturing costs can be reduced.

The perspective view of the hair clip of an embodiment The side view which shows the use condition of the hair clip of embodiment The exploded perspective view of the hair clip of an embodiment (A) is a longitudinal sectional view in the assembled state, (b) is a longitudinal sectional view in an exploded state of the hair clip of the embodiment.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the hair clip 1 of the embodiment includes a pair of clip pieces 10, a rotating shaft 20, and a torsion spring 30.

As shown in the figure, the pair of clip pieces 10 are each curved in a substantially semi-cylindrical shape and are opposed to each other while being curved outward, and their upper ends in the curved direction (circumferential direction) are rotated. They are connected by a shaft 20. The torsion spring 30 is loaded between the two clip pieces 10.
Details of the connection mode by the rotation shaft 20 and the loading mode of the torsion spring 30 will be described later.

Each clip piece 10 is between a closed position in which the lower ends in the circumferential direction approach each other and the entire hair clip 1 is closed in a cylindrical shape, and an open position in which the lower ends are separated and the cylinder is opened. The rotation shaft 20 is rotatable.
At the same time, each clip piece 10 is urged toward the closed position by the torsion spring 30.

This hair clip 1 is used when fixing the hair wound around the hair curler 2 so as not to unravel.
Specifically, each clip piece 10 is opened with a finger and placed on the hair curler 2 around which the hair is wound, and then when the hand is released, the clip piece 10 is closed by the action of the torsion spring 30, and the state shown in FIG. Thus, the hair is sandwiched between the hair clips 1 and fixed.

Here, the hair curler 2 shown in the figure is a general-purpose product comprising a small-diameter cylindrical hard core body 2a and a large-diameter cylindrical soft hair winding body 2b that covers the outer periphery of the core body 2a.
The core body 2a can be heated for a certain period of time by being charged with a built-in heater. The hair winding body 2b is configured such that the hair is wound and heat is transmitted from the core body 2a, and the heat causes waves and curls to be applied to the hair.

  More specifically, as shown in FIGS. 3 and 4, the clip piece 10 of the hair clip 1 is curved in a substantially semi-cylindrical shape with substantially the same curvature, and is a triple of the substrate 11, the cover plate 12, and the heat insulating plate 13. It has a structure.

The substrate 11 is integrally formed in a substantially semicylindrical shape from a known synthetic resin such as polyethylene, polystyrene, polypropylene, polyethylene terephthalate.
As shown in FIG. 3, a plurality of through holes 11 a extending in the circumferential direction (curving direction) of the substrate 11 and parallel to the axial direction of the semi-cylinder are provided on the peripheral surface of the substrate 11.

A rectangular tab 11b that protrudes in the radial direction of the substrate 11 is provided at the center of the upper end of the substrate 11 in the circumferential direction. A pair of tabs 11b is provided on both sides of the upper surface of the tab 11b, that is, on both ends of the substrate 11 in the axial direction. The bearing 11c is bulged and provided.
On the other hand, at the lower end portion of the substrate 11 in the circumferential direction, comb teeth 11 d are provided in parallel with the axial direction of the substrate 11.
Furthermore, a recess 11e is provided on the inner peripheral surface of the substrate 11 so that the entire region is recessed in a semi-cylindrical shape, leaving the peripheral edge.

  Similarly to the substrate 11, the lid plate 12 is integrally molded from a synthetic resin into a substantially semicylindrical shape. As shown in FIG. 3, the cover plate 12 has substantially the same axial and circumferential dimensions as the recess 11e of the substrate 11, and its thickness is slightly smaller than the depth of the recess 11e as shown in FIG. Yes.

  As shown in FIG. 3, a large number of through-holes 12 a extending in the circumferential direction of the lid plate 12 and arranged in parallel in the axial direction are provided on the circumferential surface of the lid plate 12. These through long holes 12 a are arranged so as to match the through long holes 11 a of the substrate 11 on a one-to-one basis when the cover plate 12 is fitted into the recess 11 e of the substrate 11.

The heat insulating plate 13 is formed by bending a flat metal plate into a substantially semi-cylindrical shape. The type of the metal plate is not particularly limited, and an aluminum plate, a copper plate, and an iron plate can be exemplified, but the aluminum plate is preferable because it is lightweight and inexpensive and is not easily rusted.
As shown in FIG. 3, the heat insulating plate 13 has substantially the same axial and circumferential dimensions as the recess 11e of the substrate 11 and the cover plate 12, and the thickness thereof is the same as the thickness of the cover plate 12, as shown in FIG. Then, it is almost equal to the depth of the recess 11e.

  Further, as shown in FIG. 3, a plurality of through-holes 13 a extending in the axial direction of the heat insulating plate 13 and arranged in parallel in the axial direction and the circumferential direction are provided on the peripheral surface of the heat insulating plate 13. That is, the through long holes 13 a of the heat insulating plate 13 extend in a direction substantially orthogonal to the through long holes 11 a and 12 a of the substrate 11 and the cover plate 12.

As shown in FIG. 3 and FIG. 4, the clip piece 10 includes the substrate 11, the cover plate 12, and the heat insulation plate 13, and the heat insulation plate 13 is fitted into the recess 11 e of the substrate 11, and the lid plate 12 is further fitted thereon. This is completed by closing the opening of the recess 11e.
For this reason, as shown in FIG. 1, the heat insulating plate 13 is in a state of being built in the clip piece 10. In other words, the outer surface of the clip piece 10 is made of synthetic resin, and the inside is made of metal.

  Here, it is preferable that the substrate 11 and the cover plate 12 are fixed and integrated so as not to be separated, and examples thereof include welding, adhesion, screwing, engagement by a claw, etc., but ultrasonic welding is simple. In addition, since separate members such as adhesives and screws are unnecessary, it is particularly preferable.

  In addition, since the cover plate 12 and the heat insulating plate 13 fit into the recess 11e of the substrate 11 without excess or shortage due to the dimensional relationship described above, the outer surface of the substrate 11 and the cover plate 12 is substantially flush with a step between them. This is not possible (see FIG. 4A). Therefore, the inner peripheral surface of the clip piece 10 is smooth and the hair does not get caught.

As shown in FIG. 1, the completed clip piece 10 has through-holes 11a and 12a extending in the circumferential direction of the substrate 11 and the cover plate 12 and through-holes 13a extending in the axial direction of the heat insulating plate 13 in a lattice shape. By intersecting, a gap communicating in the radial direction (the direction from the inner peripheral surface to the outer peripheral surface of the clip piece 10) is formed. For this reason, the breathability is good, and even when the hair is sandwiched, the stuffiness of the head is suppressed.
At the same time, the clip piece 10 is partially exposed to the outside through the through-holes 11 a and 12 a of the substrate 11 and the cover plate 12 as shown in FIG.

Here, as shown in FIG. 1, the pair of clip pieces 10 has bearings 11 c provided on the respective substrates 11 aligned in the axial direction of the clip, and the rotating shaft 20 is inserted therethrough as described above. Are connected to be rotatable about a rotation shaft 20.
In addition, although the material of the rotating shaft 20 is not limited, Metal is preferable on the request | requirement of intensity | strength.

Further, as shown in the figure, the torsion spring 30 is externally mounted on the rotating shaft 20, and both the leg portions are bridged between the opposing tabs 11b, so that the clip piece 10 has the lower end portions thereof as described above. Is biased toward the closed position.
At the same time, the clip pieces 10 can be opened against the urging force of the torsion spring by pinching both tabs 11b closer to each other.
In addition, since the comb tooth 11d exists in the lower end part of the clip piece 10, the comb tooth 11d bites into the hair as the torsion spring 30 is biased, and the pinching force is strengthened.

  The configuration of the hair clip 1 according to the embodiment is as described above, and since the heat retaining plate 13 having good thermal conductivity is built in each clip piece 10, the heat storage action suppresses heat dissipation of the hair curler 2. Yes. Suppressing heat dissipation makes it easier to get clean waves and curls on the hair.

Further, since the outer surface of the clip piece 10 is covered with the substrate 11 and the cover plate 12 and the heat retaining plate 13 does not directly touch the hair, it is possible to prevent the hair from being damaged or burned by heat.
In addition, a part of the heat insulating plate 13 of the clip piece 10 is exposed to the outside through the through holes 11 a and 12 a of the substrate 11 and the cover plate 12 from the recessed portion that does not contact the hair, and thus accumulates in the heat insulating plate 13. The heat generated is easily transmitted to the hair.

  In the above embodiment, the recess 11e is provided on the inner peripheral surface of the substrate 11. However, even if the recess 11e is provided on the outer peripheral surface of the substrate 11 and the heat retaining plate 13 and the cover plate 12 are fitted from the outer peripheral surface side. Good.

In the above embodiment, the patterns of the through holes 11a, 12a, and 13a extend in the circumferential direction in the substrate 11 and the cover plate 12, and extend in the axial direction in the heat insulating plate 13, but conversely. For example, the heat insulating plate 13 may extend in the axial direction.
Alternatively, in the substrate 11 or the like, the through-holes 11a and 12a extend in a state inclined in one direction (for example, rightward) with respect to the circumferential direction. For example, it may be inclined to extend leftward).
In short, the through-holes 11a and 12a of the substrate 11 and the cover plate 12 and the through-holes 13a of the heat insulating plate 13 are non-parallel, thereby crossing in a lattice shape or an oblique lattice shape. It is only necessary that a gap communicating in the radial direction of the piece 10 is generated and a part of the heat insulating plate 13 is exposed to the outside.

Furthermore, although the torsion spring 30 is used in the above embodiment, the kind of spring is not limited to this, A leaf | plate spring etc. may be sufficient.
The tab 11b and the comb teeth 11d can be omitted. The shape and position of the tab 11b can be changed, and the bearing 11c and the tab 11b may be arranged at different positions.

In the above embodiment, the clip piece 10 is constituted by the synthetic resin substrate 11 and the cover plate 12 constituting the outer surface thereof, and the metal heat insulating plate 13 constituting the inside thereof. It is not limited to this.
In short, it is sufficient that the finished clip piece 10 is made of synthetic resin on the outer surface and made of metal inside, so that heat from the hair curler can be accumulated well inside, and the outer surface is relatively low in temperature. There is no damage to the contacted hair.
For example, a substantially semi-cylindrical member made of a synthetic resin constituting the entire outer surface is provided with a substantially semi-cylindrical slit extending from the end to the inside, and the heat insulating plate 13 is inserted into the slit to create the clip piece 10. You can also.
In addition, when a substantially semi-cylindrical member constituting the entire outer surface is molded using a mold, the heat insulating plate 13 can be embedded in advance in a molten synthetic resin as a material thereof.

  The above embodiments are merely examples, and the invention is not limited thereto. The present invention is defined based on the description of the scope of claims, and all modifications can be made to the embodiments within the scope of the contents shown in the scope of claims. Shall be included.

  In this specification, the term “substantially semi-cylindrical” refers to a divided body that can be obtained by dividing a cylindrical body that can be collectively referred to as a substantially cylindrical shape such as a cylinder, an elliptic cylinder, or a long cylinder in the circumferential direction. The general shape shall be included.
