Description

HAIR HOLDING DEVICE WITH ELASTIC CLOSURE OPERATION}

The present invention relates to a hairpin that can pivotally connect the first body and the second body and bind the head.

Popular hairpins or hairclips are most commonly used as tools for fixing, decorating and styling hair. Hinge-spring hairpins for securing a human head are well known. This type of hairpin has been in use for many years and was earlier introduced in US Pat. No. 2,201,719. Such hairpins typically have a pair of opposing and hinged members, each member having a hair fixation portion and a handle portion. The hair fixing part is forced to the closed position by the elastic means, and the most widely known elastic means are the torsion springs, which give the force to close the members. To open the hairpin, the user must hold the handle part with a finger and open the hair fixing part by applying a force greater than the elastic force of the elastic means. The user places the hair fixation on both sides of the desired amount of hair while maintaining the finger force, and then releases the handle to fix the hair by fixing the hair by the torsion spring.

In addition to the hairpins described in U.S. Patent 2,201,719, several U.S. patents introduce hairpins, which have a body that is too rigid or elastic springs to hold the hair effectively, and are aesthetically pleasing whether they are hidden or exposed. Bad or not used by many users. Hairpins of this kind are described in Hart, U.S. Patents 5,520,201; US Patent 5,642,740 to Chen; Yasuda, U.S. Patent 5,787,905; Lee, U.S. Patent 5,803,096; U.S. Patent 5,842,482 to Potut; U.S. Patent 5,862,815 to Murphy; US Patent 5,873,377 to Yang; US Pat. No. 5,988,184 to Shu; Newlin, US Pat. No. 6,186,151; US Pat. No. 6,325,074 to Strawn; US Pat. No. 6,354,307 to Potut; US Patent 6,357,452 to Bolito; US Pat. No. 6,408,859 to Shyu; US Pat. No. 6,619,296 to Potut.

This hairpin has the following disadvantages. The body is too hard to hold the hair effectively so it best fits the shape of the bundled hair and cannot hold the hair firmly. As a result, the user can easily move away from the position of the hairpin. Moreover, if it has an elastic spring whether exposed or hidden, it will not look good on an external appearance. In addition, the exposed elastic spring is tangled in the user's hair, damage the hair when taking off the hairpin, as well as hurt your fingers. In addition, springs, which are critical to the life of the hairpin, are the most common component of failure. The spring also increases the weight and volume of the hairpins and is a relatively expensive component due to its metallic nature. In addition, for the manufacturer, the assembly process is complicated and expensive due to the spring.

Many attempts have been made to improve the shape and function of hairpins by replacing the springs with other elastic means or by improving the design to eliminate the springs. Inventions of this kind include U.S. Patent Nos. 6,035,863 to Mao; Lloyd, US Pat. No. 6,142,159; US Patent No. 6,311,699 to Horman.

In addition, hairpins using elastic bands with rigid or flexible body members have also been proposed. Hairpins of this kind are described in Takashima, US Pat. No. 5,535,765; See, US Pat. No. 1,533,380 to Burkhart.

Takashima's hairpins use a pair of pivotally connected body members as a means of attaching elastic bands to the hair to the hair. The rigid body members themselves do not have any hair fixation. In addition, the elastic band does not push the body member to the closed position. On the other hand, the elastic band opens the body member, and the user must give a force greater than the elastic force to insert the hairpin to the head.

Burkhart's hairpin combines a sharp comb with a hairpin. The hairpin includes a single flat arched hair comb of a hingeless elastic material. This comb is fixed to the hair by an elastic band. The comb's flesh digs into the user's hair, but there is no hair fixation. All hair fixation functions consist of elastic bands, which cover only a portion of the bundled hair. As a result, only largely bundled hair can be fixed, and hair that is as thin as a horsetail cannot be effectively fixed. In other words, Burkhart's hairpins can flatten the hair, making it impossible to create the desired styling or the hair comb may fall off.

Therefore, it would be desirable to provide a multi-purpose hairpin that improves the conventional hairpin by providing the two body members of the hairpin with elastic means that match the hair when the hair fixing part contacts the bundled hair while pushing the two body members to the closed position.

Summary of the Invention

The present invention provides a hairpin having a first and second body member pivotally connected with a hair fixation, and a method for improving the existing hairpin, while the hair fixing part is in contact with the hair while pushing the two body members to the closed position. When the elastic means corresponding to the hair is characterized in that it provides the two body members of the hairpin. The elastic means are elastic bands or elastic bands permanently or temporarily connected to the hairpins. Elastic bands or elastic bands may be connected to the body members in a linear, looped, wound and / or lace shape.

Elastic means have several important functions: to push the body member of the hairpin to the closed position to fix the bundled hair; Function that matches the form of the tied hair; The function of pushing the bundled hair to the hair fixing part of the hairpin and the inner side of the comb. As a result, the hairpin of the present invention is more secure than the conventional hairpin in that the hair is completely enclosed and fixed firmly by the hair fixing part of the hairpin, comb teeth or elastic means. More firmly. Even replacing conventional elastic means such as torsion springs with the elastic means of the present invention can further improve the hair fixation performance. As a result, cost is reduced and reliability and external aesthetics are improved.

It is possible to supplement hair fixation performance by installing elastic means on existing hairpins.

On the other hand, while the elastic means of the present invention is installed on the existing torsion spring type hairpin, the torsion spring can be removed and converted into a hairpin having only the elastic means of the present invention on the body member.

According to another feature, the present invention uses the elastic means while forming a lever means on the body member to prevent erroneous operation or sudden operation when moving between the opening and closing position on the hairpin.

The elastic means and the hairpin of the present invention may be sold in an assembled state, but may be sold separately and assembled by the user.

The present invention also provides various methods and means for connecting the elastic means to the hairpin body.

20A-F are cross-sectional views of the head for explaining various patterns of connecting the elastic means to the hairpins.

Shown in FIG. 1 is a spring-loaded hairpin 10, comprising rigid first and second body members 12, 14 pivoted to a hinge pin 16, the hinge pin being first and second. It passes through the connecting projections 18 and 20 attached to the body members. The first and second body members 12 and 14 have handle parts 30 and 32 and hair fixing parts 22 and 24, and the hair fixing part has a plurality of comb teeth 26 and 28 that bite the hair. Depends In general, the torsion springs 34 are wound around the hinge pin 16. The torsion spring is pre-stressed when the hairpin 10 is assembled, and the protruding arms at both ends push the handle portions 30 and 32 to push the first and second body members 12 and 14 to the closed position as shown. give. Although such a hairpin is useful in some cases, as described above, there are many difficulties.

2 shows a hairpin 110 of a first embodiment constructed in accordance with the present invention. This hairpin 110 is structurally similar to the hairpin 10 of FIG. 1 in many respects. Specifically, the hairpin 110 has first and second body members 112 and 114 pivotally connected to the hinge pin 116, and the hinge pin penetrates through the corresponding connecting protrusions 116 and 120 formed in the body member. The first and second body members 112 and 114 have handle portions 130 and 132 and hair fixing parts 122 and 122 '; 124 and 124', and a plurality of comb teeth 126 and 128 are arranged to be offset from each other. The torsion spring 134 is wound around the hinge pin 116. Protruding arms at both ends of the torsion spring push the handle parts 130 and 132 to prestress the torsion spring when assembling the hairpin 110 so that the first and second body members 112 and 114 are closed.

There is an important difference between the conventional hairpin 10 and the hairpin of the present invention of Figure 1 has a number of performance and advantages, the difference is in the elastic means for connecting the first and second body members. The elastic means according to the present invention may have various forms, and a rubber band or a rubber band having both ends is possible, but is not limited thereto. When the elastic means is a rubber band, there may be a means for temporarily or permanently connecting both ends or one end of the rubber band to the first and second body members 112 and 114 of the hairpin. When the elastic means is a rubber band, there may be a means for temporarily or permanently connecting the rubber band to the first and second body members 112 and 114 of the hairpin. The elastic means can be made of any material, natural or synthetic, as long as the elastic means can be stretched to some extent, such as natural rubber, artificial rubber, rubber compound, latex, neoprene and spandex.

2-5, the hairpin 110 has elastic means 136. Although the elastic means 136 of the present embodiment is illustrated as a pair of elastic bands connected to the hair fixing parts 122 'and 124', one or more elastic bands may be used and the first and second body members are not hair fixing parts. It may be connected to other parts of the fields (112, 114). The elastic means 136 may be tied to or adhered to the first and second body members 112 and 114, or as shown in FIGS. 3A-B and 4, the elastic band may be attached to the first and second body members. Attachment means 138 to be attached may be formed at one or both ends of the elastic band. As shown, the attachment means 138 takes the form of a hole 140, but may also take the form of a hook or the like. The material of the attachment means 138 may be the same as or different from the elastic band, or may be formed like the elastic band or separately formed and attached to the elastic band at the back. As shown in Figures 1 and 4, the hole size of the attachment means 138 allows the fastening means 142, such as pins, formed on the hair fixing portions 122 ', 124'.

In FIG. 5, the hairpin 110 is illustrated in the user's head. As can be seen in this figure, the elastic means 136 matches any shape of the user's head. Due to this function, and other functions of the elastic means to be described later with reference to Figure 7c the hairpin of the present invention can be fixed the hair better than the conventional hairpin 10 of FIG.

6 and 6a show other methods and means for attaching the elastic means 136 to both hair fixing portions of the pivotal hairpin, where the hair fixing portions are labeled 122 " and 124 ". In this embodiment, the attaching means 138 at both ends of the elastic means 136 is attached to the fixing means 142 'formed on the inner surface of the hair fixing parts 122 ", 124". As can be seen in Figure 6a, the fixing means 142 'is a columnar member fixed to both hair fixing parts. To fix the elastic means 136 to the hair fixing portions 122 "and 124", it is only necessary to push the holes of the attachment means 138 to the open ends of the fixing means 142 '. In order to prevent the attachment means 138 from being detached, it is preferable that the fixing means 142 'be C-shaped (see Fig. 6A). Advantages of the configuration of Figures 6 and 6a over the configuration of Figures 2-4, is that the fixing means is formed on the inner surface rather than the outer surface of the hair fixing part is better appearance.

7a-c show another embodiment of the hairpin according to the invention and the general principle of operation of all hairpins which are closed by elasticity as described above. Hairpin 210 is structurally similar in many respects to hairpin 10 of Figure 1 and hairpin 110 of Figures 2-5. Specifically, the hairpin 210 has a pair of rigid first and second body members 212 and 214 pivotally connected to the hinge pin 216, and the hinge pin has a corresponding connecting protrusion formed on the first and second body members. Through 218,220. The connecting protrusions 218 and 220 function like the lever of the elastic means 236, and the advantages thereof will be described below. The first and second body members 212 and 214 have handle portions 230 and 232 and hair fixing parts 222 and 224, and a plurality of comb teeth 226 and 228 are alternately formed at the ends of the hair fixing parts. Unlike the other embodiments described above, the hairpin 210 does not have a torsion spring for pushing the hairpin to the closed position, the elastic means 236 exerts its function, which will be described later. In addition, the various elastic means and connection method that can be used for the hairpin 210 has already been described, and the structure thereof may be inferred in FIGS. 7A-C, and thus descriptions thereof are omitted for convenience in FIGS. 7A-C. .

The hairpin 210 of FIG. 7A is in a normally closed position by the tensile force of the elastic means 236 connected to the first and second body members 212 and 214. The hairpin 210 of FIG. 7B is in a state in which the user opens by applying a force greater than the tensile force of the elastic means 236 to the handles 230 and 232. As the hairpin changes from the state of FIG. 7A to the state of FIG. 7B, the elastic means 236 extends and moves upward toward the hinge pins 216 and the connecting protrusions 218, 220 on the first and second body members 212, 214. . When the elastic means 236 is opened like this, the user's head can be put in the hairpin 210. The hairpin 210 of FIG. 7C is in a hair fixation position in which the collective hair H is placed between the hair fixing parts 222 and 224 and the comb teeth 226 and 228, and the handle portions 230 and 232 are placed.

When the hairpin 210 moves from the position of FIG. 7B to the position of FIG. 7C, the elastic means 236 contracts and descends to come into contact with the hair H. FIG. In doing so, the elastic means 236 performs several important functions: closing the first and second body members 212 and 214 of the hairpin (and thus the hair fixing parts 222 and 224 and the associated comb teeth 226 and 228). The hair is tightened), matching the user's hair shape, and pushes the collected hair (H) toward the hair fixation of the hairpin and the inner side of the comb teeth. As a result, the hairpin tightens the hair more firmly than the conventional hairpin, as well as associated hairpins or elastic means of the hair fixing part, the first and second body members, and tightly surrounds the hair. Thus, the elastic means 236 can be used to replace the elastic means, such as conventional torsion springs, while fixing the hair to the hairpin better. The result is inexpensive, safe, reliable, and aesthetically pleasing hairpins.

8A-B are schematic diagrams of a fictitious hairpin 210 'in accordance with the present invention, in which the elastic means 236 are in contact with the movement path from the lower contracted state of FIG. 7A to the upper expanded state of FIG. 7B. The elastic cover does not contact the lever means such as the connecting projections 218 and 220 of c. The following description is irrelevant to the hairpin 110 described with reference to FIGS. 2-6, which has a significant distance from the axis of the hinge pin 116 to the hair fixing parts 122 'and 124', thereby resizing the "conversion point" to be described later. This is because the danger of passing by means can be avoided.

8A-B show only the essential elements of the hairpin 210 'for convenience of description. In view of this, the hairpin 210 'includes first and second body members 212' and 214 'pivotally connected to the hinge pin 216'. The first and second body members are narrowed toward each other by the elastic means 236 '. Arrow A is a direction in which the first and second body members 212 'and 214' are unfolded. Remember that the elastic means stretches toward the hinge pins as the first and second body members are opened. The broken line D-D in FIGS. 8A-B is a reference plane on which the hinge axis of the hinge pin 216 'lies.

When the elastic means 236 'passes the "conversion point", which is the reference plane indicated by the DD line, the first and second body members are pulled in the direction of the arrow B to the limited position by the contact between the body member or the handle portion. . When the elastic means 236 'reaches the reference plane, the elastic means 236' is maximized to maximize the potential energy. As a result, if there is no lever means, the hairpin passes through the transition point with a rapid acceleration motion, which is a sudden and abnormal movement felt by the user. When such a rapid movement occurs, the user is likely to drop the hairpin while dropping or narrowing the hairpin.

9A-B are schematic diagrams of hairpins 210 constructed in accordance with FIGS. 7A-C. Again, only the basic parts of the hairpin 210 are shown for convenience of description. The first and second body members 212 and 214 are narrowed by the elastic means 236. Opening the first and second body members 212 and 214 moves in the direction of the arrow A. FIG. As the first and second body members are opened, the elastic means 236 extends while moving toward the hinge pin 216. Similarly, the break line D-D is a reference plane on which the hinge axis of the hinge pin 216 lies.

The distal ends of the connecting projections 218 and 220 form a lever apart from the reference plane D-D. When the hairpin 210 is opened as shown in FIG. 9B, the elastic means 236 is caught by the lever and cannot pass the transition point, and the hairpin 210 is not suddenly and excessively opened as shown in FIG. 8B.

Let the distance between the lever consisting of the connecting projections (218, 220) and the elastic means 236 as a reference distance. According to the inventor's observation, if the reference distance is relatively small, the elastic means comes into contact with the lever while opening the hairpin. In this case, the handlebar force is basically required to open the hairpin. However, if the reference distance is relatively long, the elastic means reach the lever relatively late when opening the hairpin. In this case, a relatively large force is required to open the hairpin, and a rapid acceleration operation occurs even with a relatively small force at the end of the conversion operation. This action is similar to the transition you experience when pulling a compound archery bow. Such rapid fluctuations in the force required to open the hairpin and rapid fluctuations in the speed at which the hairpin is opened cause a different feeling than the user experiences when the hairpin 210 'passes through the transition point described in FIG. 8B. You will not be able to adjust the hairpin. The reference distance may be reduced by increasing the distance from the reference surface D-D to the distal ends of the protrusions 218 and 220 or by arranging the elastic means 236 close to the protrusions.

In addition, although the connection of the two members with protrusions has been described, any protrusion can be used as long as it affects the elastic means when extending from the hinge axis toward the elastic means to open the hairpin. The lever may be made of the same or different material as the body member. According to this embodiment, the lever is molded together with the associated body member by injection molding or vacuum molding.

In the above description, a hinge means made of a hinge pin inserted into a protrusion formed on the body member of the hairpin is taken as an example. However, it is also possible to connect the body members to one another during the plastic molding process using a suitable plastic material to form flexible joints called "living hinges" between the body members. In this case, a suitable lever can be formed, such as a hairpin. 10 and 11, the hairpin 310 is thus configured.

The hairpin 310 has a pair of rigid first and second body members 312 and 314 pivotally connected to the living hinge 316. The first and second body members 312 and 314 have the handle portions 330 and 332 and the hair fixing parts 322 and 324, and a plurality of comb teeth 326 and 328 are alternately formed at the ends of the hair fixing parts.

Elastic means fixing slots 350 are formed at the side edges of the hair fixing parts 322 and 324 of the hairpin 310. An elastic means 336 (shown as a broken line in the drawing) for closing the first and second body members 312 and 314 is fitted into the fixing slot 350. The elastic means 336 is in the form of a rubber band wrapped around the outer surface and the inner surface of each hair fixing part. Although not shown in FIG. 11, when the user grasps the handle parts 330 and 332 and fully opens the hairpin as shown in FIGS. 10 and 11, the lever can affect the elastic means 336 to smooth the operation of the hairpin as described above. It can also be arranged inside the hair fixing government.

12 is an internal perspective view of a body member 414 of another hairpin in accordance with the present invention. The body member 414 has a connecting protrusion 420 cooperating with a connecting protrusion of a corresponding body member (not shown). The body member 414 has a handle part 432 and a hair fixing part 424, and a plurality of comb teeth 428 are formed at the ends of the hair fixing part. Body member preferably has a slot 450 for temporarily or permanently inserting the above-mentioned elastic means.

13 is a perspective view of an elastic means fixture 452 suitable for use with the body member 414 of FIG. The material of the fastener 452 may be the same as or different from the material of the body member of the hairpin. The base 454 of the fixture has a configuration that is coupled to the slot 450 of the body member 414, the elastic means according to the invention is attached to the elastic means coupling portion 456. The wall surface 458 of the base 454 of the fixture is tapered upward to engage the corresponding tapered wall surface of the slot 450 of the body member 414. Further, a pair of latch means 460 is formed on both ends of the base. When the fastener is inserted into the slot 450 from the outside of the body member 414, the latching means 460 bends inward and the outwardly projecting shoulder 462 passes through the inner surface of the body member and then pops out to the outside. 452 is fixed to the body member 414. Whether the fixture 452 is temporarily or permanently connected to the body member is determined by the rigidity of the latch means 460.

Fixture 452 is any kind of elastic means fixture that can be unfolded in the hairpin of the present invention. The fixture may be integral with the body member. Its size and shape can be anything as long as it locks the hair and locks the hair, but does not harm the hair. As will be described later, the fastener may be provided with a hole for fitting the elastic means. In addition, it may have a hook-type fastener for hanging the elastic means.

In addition, the fixture may be provided in various body members of the hairpin. In addition, the method of forming a fastener on the body member of the hairpin may be various. For example, the fixing portion may be integrally or separately formed on the handle portion, the hair fixing portion, the spring portion, the protrusion portion, the shaft portion, and / or the hair fixing tooth surface of the body member.

14 is a front view of the elastic means fixing member 538 according to the present invention. It is preferable that the fixing member 538 is made of one, and one end forms an eyelet 539 forming a hole 540, and the other end forms a hook 541. The fixing member 538 is particularly useful for connecting the rubber band type elastic means to the hairpin body member of the present invention. The rubber band-type elastic means is caught by simply inserting it into the gap 543 of the eyelet 539.

FIG. 15 is a perspective view of a rubber band type elastic means 536 having two fixing members 538 of FIG. When the fixing member 538 is connected to the elastic means 536, one hook may be connected to one fixture of the first and second body members. Then, the elastic means can be fixed to the hairpin body member in a desired shape. To finish the installation, connect the remaining hooks to the fixtures of the other fasteners.

The configuration of Figure 15 is also useful for improving the conventional hairpin since it can be connected to the hairpin without disassembling the conventional hairpin. That is, the first hook 541 can be fixed to a component that is good for fixing, such as a hinge pin, a spring, or a protrusion of the hairpin. Subsequently, when the elastic means 536 is wound around the hair fixation means of the body, the body member can be pulled inward to fix the hair therebetween and restrict the hair to match the shape of the hair. The second hook 541 can likewise be hooked to the fastener of the hairpin.

16-19 shows another example of the present invention, but for convenience of description, a hinge pin, a connecting protrusion, a lever means, etc. are omitted.

The hairpin 610 of FIG. 16 has first and second body members 612 and 614 and elastic means 636 in the form of a rubber band for pulling these body members inward. Guide means in the form of eyelets 680 are formed on both inner surfaces of the body members 612 and 614. The end 638 of the elastic means 636 is fastened to the fixture 650 through each eyelet.

The hairpin 710 of FIG. 17 has first and second body members 712 and 714 and elastic means 736 in the form of a rubber band for pulling these body members inward. Guide means in the form of hooks 780 are formed on both inner surfaces of the body members 712 and 714. The end 738 of the elastic means 736 is fastened to the fixture 750 through each hook.

The hairpin 810 of FIG. 18 has first and second body members 812 and 814 and elastic means 836 in the form of a rubber band for pulling these body members inward. A guide means in the form of a groove 880 is formed on the outer surface of the hair fixing comb of the body members 812 and 814, and the end 838 of the elastic means 836 is wound around these grooves and then fixed to the fixture 850. The groove 880 is deep enough so that the elastic means 836 does not protrude from the comb tooth outer surface.

The hairpin 910 of FIG. 19 has first and second body members 912 and 914 and elastic means 936 in the form of a rubber band for pulling these body members inward. Guide means 980 in the form of snap-in hooks or eyelets are formed on the inner surfaces of the body members 912 and 914, passing through the ends 938 of the elastic means 936 and then fixed to the fixture 950. The guide means 9l80 are firmly and permanently fitted to the walls of the body members 912 and 914.

These guide means 680, 780, 880, 980 are preferably as small as possible so as not to interfere with the hair fixation performance of the hairpin. The fasteners 650, 750, 850, 950 can be made of any of the elastic means fasteners described above. On the other hand, the fasteners (650, 750, 850, 950) may have a structure unique to the hairpin that can be used as a fixing means, such as handle portion, connecting projection, hair fixing comb, elastic arm of the torsion spring.

20A-F are cross-sectional views through the bottom of another hairpin in accordance with the present invention, showing various patterns connecting the elastic means 1036 to the hairpin. The hairpin 1010 has first and second body members 1012 and 1014 having hair fixing parts 1022 and 1024, and a plurality of comb teeth 1026 and 1028 are alternately formed at the ends of the hair fixing parts.

20A-C show various ways of connecting one elastic means 1036 in the form of a rubber band or rubber band to the hairpin. 20A shows that the elastic means for narrowing the body members 1012 and 1014 is in the form of a loop. In FIG. 20B, the elastic means for narrowing the body members 1012 and 1014 is partly looped and partly laced. 20C shows that the elastic means for narrowing the body members 1012 and 1014 is in the form of a race.

20D-F illustrate various ways of connecting two elastic means 1036 in the form of rubber bands or rubber bands to the hairpins. 20D shows that the elastic means for narrowing the body members 1012 and 1014 is in the form of a parallel loop. 20E shows that the elastic means for narrowing the body members 1012 and 1014 is in the form of crossed loops. 20F shows that the elastic means for narrowing the body members 1012 and 1014 is in the form of a race.

Although most of the elastic means are wound around the outer surfaces of the comb teeth 1026 and 1028 of the body members 1012 and 1014, the elastic means is brought into contact with either or both of the inner and outer surfaces of the body member. It may be. In addition, the type, number, length, elasticity, and material of the elastic means used for the hairpin constructed in accordance with the present invention may be selected as long as the above advantages are shown. It is also possible to permanently or temporarily attach the elastic means to the body member when forming the hairpin (ie, during the molding process) or afterwards.

The main disadvantage of conventional hairpins that narrow the hair fixation with torsion springs is that the torsion springs may fail. These torsion springs cannot be removed or replaced. That is, when the torsion spring is broken, the conventional hairpin cannot be used and the head can no longer be fixed. In the case of the present invention, it can be replaced by removing the elastic means. Thus, when the elastic means loses its elasticity or fails, the user can exchange the elastic means for a new one. It is a great advantage for hairpin users because it is possible to increase the life of the hairpin simply by replacing parts such as elastic means, which have a high risk of failure. Instead of purchasing a new product each time the elastic means fails, consumers can continue to use existing hairpins by replacing only the elastic means.

According to another feature of the invention, the hairpin and the elastic means are sold in a package, and the end user may connect the elastic means to the hairpin. Instructions for assembling the resilient means to the hairpin can be attached when the package is sold. On the other hand, the end user may install the elastic means to the hairpin as desired by the user.
