Definitions
- the present invention relates to hair care and styling and, more particularly, to hairpins and methods for securing the hair of a user.
- Hair pins have typically been formed with a permanent opening to receive hair and two or more arms positioned a set distance from one another. Once positioned within the hair, the arms generally remain at the set distance from one another. To hold the pin in place, typical hair pins have primarily relied on the frictional forces between the arms of the hair pin and the hair. However, typically hair pins have a tendency to be easily dislodged from hair because the hair pins are not capable of being closed.
- Bobby pins have typically been formed with two arms biased against one another.
- Bobby pins typically have an angled opening that funnels hair between the first and second arms.
- the hair biases the first and second arms apart and is held in place by the resilient nature of the arms biasing them toward one another.
- bobby pins are not as easily dislodged from hair as hair pins, bobby pins cannot typically receive the volume of hair between their arms because the arms of the bobby pin are biased together and the opening for receiving hair is typically limited by design to being relatively small.
- Barrettes are typically more ornamental in nature and are held in the hair with a wide range of clasps, arms, rods and hooks. Barrettes may also be configured to hold and/or position hair.
- an arm is hinged to an ornamental body and engages a clasp to secure the barrette in the hair of a user.
- an ornamental body defines two holes to receive a rod which secures a users hair between the ornamental body and the rod.

Description
- 1. Summary of the Invention
- The present invention relates to hair care and styling and, more particularly, to hairpins and methods for securing the hair of a user.
- 2. Description of the Related Art
- Historically, a wide range of hair pins, bobby pins, and barrettes have been used to secure and form hair. Hair pins have typically been formed with a permanent opening to receive hair and two or more arms positioned a set distance from one another. Once positioned within the hair, the arms generally remain at the set distance from one another. To hold the pin in place, typical hair pins have primarily relied on the frictional forces between the arms of the hair pin and the hair. However, typically hair pins have a tendency to be easily dislodged from hair because the hair pins are not capable of being closed. Bobby pins have typically been formed with two arms biased against one another. Bobby pins typically have an angled opening that funnels hair between the first and second arms. The hair biases the first and second arms apart and is held in place by the resilient nature of the arms biasing them toward one another. Although bobby pins are not as easily dislodged from hair as hair pins, bobby pins cannot typically receive the volume of hair between their arms because the arms of the bobby pin are biased together and the opening for receiving hair is typically limited by design to being relatively small. Barrettes are typically more ornamental in nature and are held in the hair with a wide range of clasps, arms, rods and hooks. Barrettes may also be configured to hold and/or position hair. With many barrettes, an arm is hinged to an ornamental body and engages a clasp to secure the barrette in the hair of a user. With other barrettes, an ornamental body defines two holes to receive a rod which secures a users hair between the ornamental body and the rod. Although barrettes may be constructed to securely hold a relatively large volume of hair, barrettes are frequently large and expensive to manufacture.

In one aspect, thefirst locking extension 18 and thesecond locking member 20 may have acoating 34. Thecoating 34 may be applied from along at least a portion of at least one of thefirst locking extension 18 and thesecond locking member 20. Thecoating 34 may enhance the ability of thefirst locking extension 18 and thesecond locking member 20 to be relatively secured to one another. -
First arm 14 may define firstlongitudinal axis 114 andsecond arm 16 may define secondlongitudinal axis 116. Typically,first arm 14 is coextensive over at least a portion of its length with firstlongitudinal axis 114. Similarly,second arm 16 may be coextensive over at least a portion of its length with secondlongitudinal axis 116. In another aspect,first arm 14 andsecond arm 16 lie aplane 100 along at least a portion of their length whenapparatus 1 is in a relaxed position. In still another aspect,first arm 14 may define firstlongitudinal axis 114 andsecond arm 16 may define secondlongitudinal axis 116 and the firstlongitudinal axis 114 and the secondlongitudinal axis 116 may define aplane 100. - First locking
extension 18 andsecond locking extension 20 are typically secured, respectively, to the second ends offirst arm 14 andsecond arm 16. In one aspect,first locking extension 18 andsecond locking extension 20 are linear along their length. In another aspect, thefirst locking extension 18 andsecond locking extension 20 are curved along at least a portion of their length. First lockingextension 18 andsecond locking extension 20 are generally configured to interlock with one another to holdfirst arm 14 andsecond arm 16 in a closed position which closes opening 52 to secure hair between at leastfirst arm 14 andsecond arm 16. The junction between thefirst arm 14 and thefirst locking extension 18 may form afirst bend 22 which directs first locking extension away from the firstlongitudinal axis 114. The junction between thesecond arm 16 and thesecond locking extension 20 may form asecond bend 24 which directs first locking extension away from the secondlongitudinal axis 116. Thefirst bend 22 and thesecond bend 24 may be in the form of a sharp angle, as illustrated, or a curve. In either case, the directing offirst locking extension 18 andsecond locking extension 20 away from the firstlongitudinal axis 114 and secondlongitudinal axis 116 by thefirst bend 22 andsecond bend 24, respectively, may permit thefirst locking extension 18 andsecond locking extension 20 to engage one another and hold opening 52 closed position. -
First bend 22 andsecond bend 24 may form the same orsimilar angles apparatus 1 is in a relaxed and open configuration. In other aspects,first bend 22 andsecond bend 24 may formed atdifferent angles FIG. 2 ,first angle 122 is about 45 degrees andsecond angle 124 is about 30 degrees. Thefirst bend 22 andsecond bend 24 typically formangles longitudinal axis first locking extension 18 andsecond locking extension 20 are secured atrespective angles apparatus 1 as is generally illustrated throughout the figures. In another aspect,first locking extension 18 extends fromfirst arm 14 at afirst angle 122 from the firstlongitudinal axis 114 andsecond locking extension 20 extends fromsecond arm 12 at asecond angle 124 from the secondlongitudinal axis 116. In yet another aspect, thefirst bend 22 may form afirst angle 122 that positions at least a portion offirst locking extension 18 into a region on a first side ofplane 100 andsecond bend 24 may form asecond angle 124 that positions at least a portion ofsecond locking extension 20 into a second region on the opposite side ofplane 100. Accordingly, thefirst locking extension 18 and thesecond locking extension 20 may be overlapped to holdopening 52 in a closed position. In one aspect, thefirst bend 22 and thesecond bend 24 may tend to nest together whenfirst locking extension 18 and thesecond locking extension 20 overlap. - End caps 26, 28 may be provided at the terminal ends of
first locking extension 18 andsecond locking extension 20. End caps 26, 28 may be integral with or secured to the lockingextensions First end cap 26 andsecond end cap 28 may provide atraumatic tips forfirst locking extension 18 andsecond locking extension 20, respectively. In another aspect,first end cap 26 andsecond end cap 28, independently or cooperatively, may maintain or assist in maintainingfirst locking extension 18 andsecond locking extension 20 in a locked position maintain opening 52 in a closed position and secure hair withinspace 50. In doing so,first end cap 26 may abut one or more ofsecond locking extension 20 andsecond end cap 28. Similarly,second end cap 28 may abut one or more offirst locking extension 18 andfirst end cap 26. In one aspect, acoating 34 may be applied over one or both of thefirst end cap 26 and thesecond end cap 28. - An exemplary embodiment of an
