The present invention relates generally to hairstyling accessories, and, in particular, to hair clips with user comfort features.
Hair clips such as claw clips and jaw clips come in different designs and sizes, and are typically worn in the hair for different styling solutions. Conventional hair clips include two rigid body members (e.g., made of a hard plastic) that are pivotally coupled together by a spring-biased hinge. The body members each include a handle portion, a hair-gripping portion with teeth, and an intermediate portion therebetween where the rigid bodies are pivotally coupled together. When a user wearing such a hair clip rests her head back against a hard surface with the hair clip between her head and the surface, the rigid body tends to cause discomfort. The hard surface tends to cause the hair clip to dig into the wear's head, thereby causing the discomfort. This is a common problem that is especially an issue for women who wear hair clips to keep their hair out of the way while working out on exercise equipment, while riding in a car and resting their head back against the headrest, etc.
Accordingly, it can be seen that needs exist for improved hair clips that do not cause a wearer discomfort from resting her head back against a hard surface. It is to the provision of solutions to this and other problems that the present invention is primarily directed.
Generally described, the present invention provides a hair clip including two body members and a spring-biased hinge. The body members each have a handle section and a hair-gripping section (e.g., with teeth), and the hinge pivotally couples the body members together so that they pivot between a closed position and an open position. In addition, the hair clip includes one or more flexing comfort features that permit the hair clip to deflect when a wearer rests her head back against a hard surface, thereby reducing wearer discomfort. In some embodiments the hair clip includes only a handle-flexing comfort feature, in some embodiments the hair clip includes only a teeth-flexing comfort feature, and in some embodiments the hair clip includes both a handle-flexing comfort feature and a teeth-flexing comfort feature.
In an example handle-flexing comfort feature, each handle section includes at least one handle-deflecting opening in it to form at least one laterally adjacent handle-flexing region where the handle sections can deflect outwardly into a low-profile flexed position. In this way, when a wearer rests her head back against a hard surface, the hair clip deflects at the handle-flexing region to absorb some of the impact and thereby reduce wearer discomfort.
In an example embodiment, the handle-deflecting openings are provided by an elongated recess formed into a lateral thickness of each handle section. Each of the elongated recesses extends a lateral length of the respective handle section where there is any material (e.g., the handle sections may include central through-holes where there is no material). Also, the elongated recesses may be formed in inner surfaces of the handle sections.
Furthermore, the handle sections may include mechanical stops that limit inward deflection of the handle sections when the user presses the handle sections together inwardly and the handle sections begin to deflect inwardly. For example, if each of the handle-deflecting openings is provided by an elongated recess formed into a lateral thickness of the respective handle section through an inner surface of the handle section, then the mechanical stops may be provided by facing inner surfaces of the recess. The facing inner surfaces interfere with each other when the handle sections are pivoted together toward the open position and the handle sections begin to deflect inwardly. In addition, at least one extension member may be provided protruding into one of the recesses and defining one of the recess inner surfaces so that the recess inner surfaces interfere with each other sooner when the handle sections are pivoted together. Moreover, each of the handle sections may includes a built-up region or other protrusion into which the recess is formed to provide a larger surface area of the recess inner surfaces.
In an example teeth-flexing comfort feature, each hair-gripping section includes at least one teeth-deflecting opening in it to form at least one laterally adjacent teeth-flexing region where the hair-gripping sections can deflect into a low-profile flexed position. In this way, when a wearer rests her head back against a hard surface, the hair clip deflects at the teeth-flexing region to absorb some of the impact and thereby reduce wearer discomfort.
In an example embodiment, the handle-deflecting openings are provided by a single elongated through-opening extending through a lateral thickness of each of the respective hair-gripping sections. Each of the hair-gripping sections includes two outer-positioned side portions with the respective elongated opening centrally formed between them such that the side portions define the teeth-flexing regions. Furthermore, each of the hair-gripping sections may include teeth, and each of the elongated handle-deflecting openings may extend laterally longer than the teeth or the handle section.
The specific techniques and structures employed by the invention to improve over the drawbacks of the prior devices and methods and accomplish the advantages described herein will become apparent from the following detailed description of the example embodiments of the invention and the appended drawings and claims.
Generally described, the present invention provides a hair clip having two body members that are pivotally coupled together by a spring-biased hinge mechanism. The hair clip includes one or more flexing comfort features that permit the body members to deflect dynamically upon impact with a hard surface so that they do not dig into the wearer's head, thereby reducing wearer discomfort.
In the depicted embodiment, the handle-deflecting openings 22 are provided by recesses that are formed in the inner surfaces 24 of the handle sections 16, that extend a recess depth D into the thickness T2 of the handle sections, that extend a recess width W into the handle sections, and that extend the entire length L of that portion of the handle sections where there is any material (see
As shown in
In order to prevent the flexing regions 30 of the handle sections 16 from deflecting too much (i.e., such that the hair clip 10 cannot be opened) when a user presses inward (toward each other) on the handle sections to open the hair clip, the handle flexing regions may include mechanical stops. In the depicted embodiment, for example, the mechanical stops are provided by first and second facing inner surfaces 34 and 36 of the handle-deflecting openings 22 that interfere with each other when the user presses the handle sections 16 together inwardly and the handle sections begin to deflect inwardly. In alternative embodiments, the mechanical stops are provided by posts, wedges, bars, or other interference members extending inwardly from the handles and positioned with the handle-deflecting openings between them.
In order to provide a sufficiently large width W of the flexing region 30 to permit the handle sections 16 to deflect readily as desired, one or both of the first and second inner surfaces 34 and 36 may be defined by extension members 38 that protrude into the handle-deflecting openings 22 (see
In addition, the handle sections 16 may include protrusions 40 (see
Accordingly, the handle sections 16 are able to fold down flat in one direction (outwardly apart) to a low-profile flexed position when the user rests her head back against a hard surface (see
The hair clip 10 can be made by conventional manufacturing techniques using conventional materials. For example, in typical commercial embodiments the body members 12 are injection molded of a soft plastic such as acrylonitrile butadiene styrene (ABS), nylon, polypropylene (PP), polyethylene (PE), acrylic, polyvinyl chloride (PVC), or another elastically deformable, resilient material. The design of the handle sections 16, with the handle-deflecting openings 22 and the flexing regions 30, inherently allows for some deflection as long as a material permitting a minimal amount of resilient, elastic deformation is used. In some embodiments, the entire body members are made of the same resilient, elastically deformable material. In some other embodiments, the flexing regions are made of the resilient, elastically deformable material, and the remainder of the body members is made of a rigid material (e.g., hard plastic). In still other embodiments, the flexing regions and the portions of the handle sections immediately adjacent them are made of the resilient, elastically deformable material, and the remainder of the body members is made of a rigid material (e.g., hard plastic). And in yet still other embodiments, the inwardly protruding ribs are made of a rigid material (e.g., hard plastic) to provide the mechanical stops, and the remainder of the body members is made of the resilient, elastically deformable material to permit the desired outward deflection.
In typical commercial embodiments, the teeth-deflecting openings 54 are positioned in the hair-gripping sections 18 between the intermediate section 17 and the teeth 20. The teeth-deflecting openings 54 may be provided by a single elongated through-opening in each hair-gripping sections that is laterally longer than the teeth or the handle section and that has a decorative shape, for example as shown in
In the depicted embodiment, the teeth-deflecting openings 54 are provided by centrally positioned through-holes that extend all the way through the thickness T of the hair-gripping sections 18 and that have a length and width defining the flexing regions 50 as side-portions of the hair-gripping sections, with the side-portion flexing regions having a width W and a cumulative length L. In typical commercial embodiments, there are at least two side-portion flexing regions 50, with the two side-portions at the outer edges of the hair-gripping sections 18 and the teeth-deflecting opening 54 therebetween. This arrangement minimizes any rotation of the hair-gripping sections about an axis that is perpendicular to the plane of the page on which
In typical commercial embodiments, the flexing regions 50 have a thickness T of about 1.8 mm-2.0 mm and the teeth-deflecting openings 54 define the flexing regions with a width W of about 1.25 mm-8.0 mm and a length L of about 4.0 mm-5.0 mm. The length L is the length of the hair-gripping sections 18 where there is any material (i.e., the cumulative length of the side-portion flexing regions 50, or the overall length of the hair-gripping sections less the length of the teeth-deflecting openings 54 along the flexing lines 52). So each of the two depicted side-portion flexing regions 50 has a length L/2 of about 2.0 mm-2.5 mm. These dimensions are provided for illustration purposes only and are not intended to be limiting of the invention, and it is within the capability of persons of ordinary skill in the art to use other dimensions than those provided herein. Accordingly, alternative embodiments contemplated by the present invention include hair clips with different dimensions and arrangements of the teeth-deflecting openings and teeth-flexing regions than those expressly set forth herein.
In some such alternative embodiments, the teeth-deflecting openings are provided by recesses with a semi-circular, triangular, or other regular or irregular shape, are provided by a series of elongated recesses (e.g., channels) spaced apart on the hair-gripping from adjacent the intermediate section out toward the outer free ends of the teeth, and/or are provided by a series or array of through-holes extending all the way through the thickness of the hair-gripping sections but not extending the entire length of the hair-gripping sections (e.g., they form perforated flexing regions). In alternative embodiments in which the teeth-deflecting openings are provided by recesses in the lateral thickness of the hair-gripping sections, mechanical stops (e.g., of the type described above) may be provided that limit outward/apart deflection while permitting inward/together deflection to the low-profile flexed position. In other alternative embodiments, the teeth-deflecting openings extend only a portion of the way through the lateral thickness T of the hair-gripping sections and extend the entire lateral length of the hair-gripping sections (e.g., they are formed by one or more elongated recesses similar to the handle-deflecting openings described herein), and/or more than one of them is formed on each of the handle sections.
The hinge mechanism 14 creates a spring-biased tension on the hair-gripping sections 18, which are able to flex somewhat (particularly the teeth 20) independent of the flexing regions 50. That is, the hair-gripping sections 18 of typical embodiments allow for some amount of deflection under loading or impact. This is particularly the case when fabricating the body members 12 of a resilient, elastically deformable material, as described above. In some embodiments, the flexing regions are made of the resilient, elastically deformable material, and the remainder of the body members (or at least the remainder of the hair-gripping sections) is made of a rigid material (e.g., hard plastic).
In other alternative embodiments, the present invention includes hair clips other than the depicted claw clips that have the same or similar comfort features. Such other hair clips include jaw clips, barrettes, etc. Persons skilled in the art will understand how to modify such hair clip designs to incorporate the comfort features disclosed herein. For example, in an alternative embodiment in which the hair clip is a barrette, the hair-gripping sections of the body members to not include the teeth of the embodiments described herein.
It is to be understood that this invention is not limited to the specific devices, methods, conditions, or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only. Thus, the terminology is intended to be broadly construed and is not intended to be limiting of the claimed invention. For example, as used in the specification including the appended claims, the singular forms “a,” “an,” and “one” include the plural, the term “or” means “and/or,” and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. In addition, any methods described herein are not intended to be limited to the sequence of steps described but can be carried out in other sequences, unless expressly stated otherwise herein.
While the invention has been shown and described in exemplary forms, it will be apparent to those skilled in the art that many modifications, additions, and deletions can be made therein without departing from the spirit and scope of the invention as defined by the following claims.
