Description

Hair pins {Hair pin}

The present invention relates to a hairpin for pinching and arranging hair, and more particularly, to a hairpin with improved spring force structure that exerts forceps on the hinge side of the hairpin.

The best prior art associated with the hairpin of the present invention is shown in FIG. 5. The hairpin disclosed in FIG. 5 is developed by Kim Cheon Joong, who is engaged in the same industry, and registered with the Korean Patent Office on 10/31/2000 under Utility Registration No. 20-209892.

According to this prior art, the pincer piece 20 having a predetermined length as the main body of the hairpin, the hair holding portion 22 of the corrugated shape is formed on the lower side and the hinge portion 24 is formed at one end; A plate spring 30 having one end fixed to the other end of the fixing forceps piece 20 by being fixed to the fixing jaw 26 formed on the fixing forceps piece 20 and the other end being a free end; The bending end portion 42 is connected to the hinge portion 24 formed on the fixing forceps piece 20 by a hinge means to be rotatable at a predetermined angle, and the end of the bending end portion 42 is free of the leaf spring 30. In contact with the end is opened at an angle from the fixing forceps piece 20 and then rotated by the elastic restoring force of the leaf spring 30 to grab the hair with the hair holding portion 22 of the fixing forceps piece 20 and the other end Exposed longer from one end of the fixing forceps piece 20 is composed of a movable tension pin 40 to serve as a finger grip 44.

The hairpin configured as described above uses a bending elastic resilience force of the leaf spring 30 and has a structure in which the free end of the leaf spring 30 is pressed against the bending end portion 42 of the movable tension forceps pin 40. Therefore, the force grabbing the hair comes from the bending elastic repulsion force of the leaf spring (30).

By the way, when looking at the installation structure of the leaf spring 30, the other free end is bent to the bending end portion 42 of the movable tension tong piece 40 in the state where one end is fixed to the fixing jaw 26 of the fixing forceps piece 20 Since the elastic force is in contact, the amount of deformation used for the leaf spring 30 to exert the elastic force is inevitably small.

Therefore, in the case of the hairpin as shown in FIG. 5, the holding force grasping the head is small. If the fixing force is small, the wearing force of the hairpin cannot be trusted.

In order to solve this problem, in order to increase the elastic deformation amount of the leaf spring 30, the height from the hinge pin 42a of the movable tension forceps pin 40 to the end surface of the bending end 42 should be increased considerably. If you open the tong pin 40 is to have a problem that is too large.

As described above, the hairpin of FIG. 5 is opened and closed in a one-touch manner, and is conveniently configured to be used as a structure worn on the head, but the leaf spring 30 that exerts force to grab hair is supported by a cantilever structure. The elasticity is weak and it is difficult to secure the fixing force to grab the head, so the wearing reliability is low.

The present invention was devised in view of the above circumstances, and improved the fixing force of the hair to come out from the double elastic pressure structure exerting the spring force at two places of the hinge part so as to increase the grip force and secure the wearing reliability. The purpose is to provide a hairpin.

Another object of the present invention is to provide a hairpin with a simple configuration to lower the production cost.

1 to 4, the reference numeral 110 is a fixing forceps piece.

The fixing clip piece 110 is made of an elastic metal plate as a part that enters the hair.

The fixing tong piece 110 is formed with a headrest 115 forming an arch from one side to the other side to be worn on the user's head. One end of the headrest portion 115 has a bending hinge elastic portion 112 that extends in a curved shape toward the other end, and a hinge portion 113 extending from the bending hinge elastic portion 112. In the present embodiment, the hinge portion 113 is formed to be bent in a circular shape at the end of the bending hinge elastic portion 112.

At this time, the cross-sectional structure of the bending hinge elastic portion 112 has a function of exerting elastic resilience while being elastically deformed when subjected to external force as a bending type. Therefore, the surface of the bending hinge elastic portion 112 may be formed beads (not shown) in order to have a stronger elastic rigid force.

In addition, the head restraint portion 115 of the fixing forceps piece 110 includes an elastic rigid body 114 having a semicircular bead cross section as shown in FIG. 4 at both side edges in the longitudinal direction. The elastic rigid body 114 not only increases the bending rigidity of the fixing forceps piece 110 itself, but also the holding force or the opening force, respectively, when the movable forceps piece 120 to be described later is closed as shown in FIG. 2A or opened as shown in FIG. 2B. It adds elastic resilience to the body. In addition, the elastic rigid body 114 prevents the movable forceps piece 120 described later from being moved in the width direction in a hinged state to the fixing forceps piece 110. Therefore, the cross-sectional structure of the elastic rigid body portion 114 is not limited thereto, and may be configured with various polygonal cross-sectional structures such as triangular and square.

Reference numeral 120 is a hinge to one side end of the fixing forceps piece 110, the movable forceps piece to pinch the hair in cooperation with the fixed forceps piece 110, the present invention is a fixed forceps piece 110 and the movable forceps piece ( 120 is coupled to the hairpin 100 as shown in FIG.

The hair clip part 121 constituting the movable clip piece 120 has an approximately equal arch shape with the headrest portion 115 of the fixing clip piece 110, and is made of a general metal plate or an elastic metal plate material.

On one side of the hair clip portion 121 has a hinge portion (122) coupled to the hinge portion 113 and the hinge pin 130 of the fixing forceps piece 110, the hinge portion ( The cam portion 123 protrudes from the outer edge of the cam 122, and the cam portion 123 includes a rotational critical vertex 123a for forming a rotational critical point for inducing opening and closing operation of the movable forceps piece 120.

The pivotal critical point 123a is in contact with the end face of the elastic rigid body 114 side of the fixing clip piece 110 by the elastic repulsive force of the bending hinge elastic portion 112. In the present embodiment, the cam portion 123 is substantially triangular, and when the position of the rotation critical vertex 123a is located on the center line L of the hinge portion 113 with the pivotal critical vertex 123a as the critical point, FIG. 2B. As described above, the opening of the movable tongs 120 is induced, and on the contrary, when the position thereof is on the right side, the closing of the movable tongs 120 is induced as shown in FIG. 2A.

And the end portion of the hinge portion 122 side of the movable tongs 120 is provided with a stop end 127 as shown in Figure 3 to limit the opening degree from the fixing tongs 110.

The stop end 127, for example, when the movable forceps piece 120 is opened about 45 degrees to contact the outer surface of the bending hinge elastic portion 112 side of the fixed forceps piece 110 to open the movable forceps piece 120. You can limit it.

On the other hand, the present invention can put the user's finger between the movable forceps piece 120 and the free end of the fixed forceps piece 110 at the opposite side end of the hinge portion 122 of the movable forceps piece 120. The upwardly raised jaw 125 has a slope that provides a space.

At this time, the end of the upward raising jaw 125 is preferably configured to be disposed at least inward from the end of the fixing forceps piece (110). This is to put the finger on the end of the fixing forceps piece 110 so that the movable forceps piece 120 can be easily opened.

A plurality of hair gripping portions 126 protruding in a substantially triangular shape toward the head restraint portion 115 of the fixing forceps piece 110 in the longitudinal direction both ends of the hair tongs 121 of the movable forceps piece 120. It is provided. The hair gripping portion 126 penetrates into the bundle of hair that is clamped between the fixed forceps piece 110 and the movable forceps piece 120 to increase the bite force.

The hairpin action of the present embodiment configured as described above will be described.

When the movable forceps piece 120 is opened to the maximum from the fixed forceps piece 110 as shown in FIG. 2B, the stop end portion 127 of the movable forceps piece 120 side of the fixing forceps piece 110 side of the elastic hinge 112 is bent. The maximum opening amount of the movable forceps piece 120 is determined in contact with the outer surface.

At this time, the rotational critical point 123a of the cam part 123 is positioned on the left side with respect to the center line L of the hinge pin 130 as shown in FIG. 2B, and the pivotal critical point 123a is the elastic rigid body 114. The point of contact with the bead end face of the ()), the rotational critical point (123a) of the cam portion 123 is subjected to the elastic repulsion force of the bending hinge elastic portion 112 while contacting the elastic rigid body portion (114).

Therefore, in the state as shown in FIG. 2B, the distance between the center of the hinge pin 130 and the rotational critical vertex 123a is set as a radius, and is opened on the movable forceps piece 120 by the elastic repulsive pressing force of the bending hinge elastic part 112. The rotational force acts in the direction.

In such a state, when the fixed forceps piece 110 is inserted into the hair and the movable forceps piece 120 is closed as shown in FIG. 2A, the position of the rotational critical point 123a formed in the cam part 123 is changed. When the position of the rotational critical vertex 123a reaches the center line L of the hinge pin 130, the bending hinge elastic part 112 has elastic repulsion force at the maximum bending deformation amount.

Subsequently, when the rotational critical vertex 123a position of the cam portion 123 deviates to the right from the center line L of the hinge pin 130, the elastic repulsive force of the bending hinge elastic portion 112 having the deformation position at the highest vertex is shown in FIG. 2A. As described above, the closing of the movable forceps piece 120 is easily performed by a one-touch operation.

When the movable forceps piece 120 is closed in such a manner as to grab the hair, the position of the rotational critical point 123a of the cam part 123 is shifted to the right from the center line L of the hinge pin 130 to the right of the elastic body part 114. Since it is in contact with the end surface of the bead, the distance between the center of the hinge pin 130 and the rotational critical vertex 123a is a radius, and the closing force of the movable forceps piece 120 is caused by the elastic bending repulsion force of the bending hinge elastic part 112. Is generated, and this closing force acts as a fixing force of the hair.

At the same time, as the elastic rigid body 114 supporting the pivotal critical point 123a adds the elastic repulsive force to fix the hair together with the elastic force of the bending elastic part 112, the movable forceps piece 120 is the hair. It can secure a firm and strong fixing force in the state of holding.

Next, to loosen the hairpin 100 worn on the hair, when the upper lifting jaw 125 is flipped with a finger, the movable forceps piece 120 is opened to overcome the elastic force of the elastic part 112 bent by the opposite action above. And, the fixing forceps 110 can be easily removed from the hair.

In the above embodiment, the bending hinge elastic part 112 is formed by integrally bending the clamping forceps 110, but the present invention has a head restraint part 115 except the bending hinge elastic part 112 as a body. It may be made of a plastic material, and the bending hinge elastic part 112 may be manufactured separately from an elastic metal to be combined with an insert.

In addition, the present invention can be configured to attach a conventional decorative member to the hair clip portion 121 of the movable clip piece 120 as a conventional technique to form a hairpin.

As described above, according to the hairpin of the present invention, as shown in the related art, the rotational threshold provided in the movable clamping piece side cam part is not provided with the elastic deformation of the flat spring in the longitudinal direction, but the bending hinge elastic part provided on the fixing clamp piece side. The elastic repulsion force generated by deforming to the vertex and the elastic force supporting structure of the elastic rigid body generates hair clamping force, thereby substantially improving the fixing force and improving the wearing force, and eliminating the number of parts and eliminating assembly by eliminating the plate spring as in the prior art. The manufacturing cost can be reduced.
