The present disclosure relates generally to clasps and clips for retaining strands of hair, and more particularly, to clasps and clips having one or more frictional members that improve gripping of strands of hair.
Barrettes have been developed that include soft materials that are attached to standard metal barrette parts. Typically these are decorative and do not affect the performance of the barrette with regard to its ability to grip hair.
Devices for retaining hair, such as barrettes, bobby pins, claw clips, and hair clips, are generally known in the art. These devices come in various shapes and sizes including various adornments to improve the esthetic appeal of the hair retaining device. One of the ongoing difficulties with these devices, however, is the inability to prevent these devices from sliding off of or moving relative to the strands of hair to be engaged and retained by the devices. For example, during normal movement throughout the day these devices tend to lose their grip around the strands of hair, thereby loosening the bundle of hair the devices are intended to retain.
One such device is disclosed in U.S. Pat. No. 6,257,251 to Burleson et al. which discloses a cushion coated hair clip having low friction surfaces. The hair clip includes a layer of compressible, resilient cushion material such as natural rubber or elastomer synthetic resin material, or cellular plastic foam that is bonded onto the hair engaging surfaces. A thick non-porous outer coating layer is applied to the compressible cushion layers for providing smooth, low friction, non-sticking surfacing for directly engaging the hair.
Another such device is disclosed in U.S. Pat. No. 5,996,593 to Horman which discloses a hair clip. The hair clip includes an alternating sequence of rubber teeth secured to surfaces of each of two clamping arms which are in an interlocking mating relationship, thereby providing for a greater surface area between the clamping arms of the hair clip.
Another such device is disclosed in U.S. Pat. No. 3,590,830 to Hannum which discloses a barrette. The barrette includes a pair of hingedly connected outer and inner body members. The first body member is provided with means for grippingly, non-slidably engaging the hair of the wearer. The other body member is provided with lifting means, including means for manually retracting and extending the lift means relative to the body member to permit unhindered insertion of the body member in the hair of the user.
These and similar retaining devices, however, do not provide the desired gripping ability for retaining a bundle of hair, or are too costly to manufacturer, and/or cause damage to the user's hair.
U.S. Patent Application Publication No. 2006/0162738 A1 discloses a hair retaining clip that includes a high friction material disposed on a locking arm.
In accordance with one aspect of the invention, an elastomeric member is used in the place of a typical leaf spring in a barrette. The elastomeric member may be made from a low-durometer material, and/or may be filled with a liquid, gel, or gas, and may also protrude through a top portion of the barrette and serve as a decorative element.
While the method and device described herein are susceptible to various modifications and alternative constructions, certain illustrative embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the disclosure and the appended claims.
Although the following text sets forth a detailed description of numerous different embodiments of the invention, it should be understood that the legal scope of the invention is defined by the words of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment of the invention since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims defining the invention.
It should also be understood that, unless a term is expressly defined in this patent using the sentence “As used herein, the term ‘——————’ is hereby defined to mean . . . ” or a similar sentence, there is no intent to limit the meaning of that term, either expressly or by implication, beyond its plain or ordinary meaning, and such term should not be interpreted to be limited in scope based on any statement made in any section of this patent (other than the language of the claims). To the extent that any term recited in the claims at the end of this patent is referred to in this patent in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term by limited, by implication or otherwise, to that single meaning. Finally, unless a claim element is defined by reciting the word “means” and a function without the recital of any structure, it is not intended that the scope of any claim element be interpreted based on the application of 35 U.S.C. §112, sixth paragraph.
Referring now to the drawings and with specific reference initially to
Alternatively, the soft durometer elastomeric body 30 may be pre-inflated and sealed, or may be a solid piece without an interior cavity, and the bulb-type pump 36 may be omitted. As a further alternative, any appropriate pump mechanism other than a bulb-type pump 36 may be used to inflate the soft durometer elastomeric body 30.

Certain features that may be common to all of the aforementioned embodiments will now be discussed. The upper clip portions 22, 42, 62 and 82 may be made from a relatively hard material, such as injection molded plastic, metallic material, wood, ceramic, or similar materials. The lower clip portions 24, 44, 64 and 84 may also be made from a relatively hard material but may function best if manufactured from a material that permits the lower clip portion to flex, such as for example spring steel or similar materials. The soft durometer elastomeric bodies 30, 50, 70 and 90 may be made from any suitable material, such as an over molded TPE that may be solid material or that may be filled with any suitable fluid, such as air, water, a gel material, or any other suitable material. Soft durometer elastomeric bodies 30, 50, 70 and 90 replace an upper leaf spring that is typically included in similar hair retaining clips or barrettes. The upper protrusions 52, 72 and the upper surface 92 may be used for decoration and/or to house a bulb-type pump similar to the bulb-type pump 36 of
The above exemplary embodiments may be varied or altered to achieve and create similar, additional or alternative features. For example, even though the above exemplary embodiments relate to certain types of hair retaining clips, the spirit and scope of the invention covers other types of hair clips, such as other types of barrettes, snap clips, living hinge clips, etc. For example, barrettes or other hair clips currently on the market could be altered by applying a gripping or friction member in the form of a soft durometer elastomeric body.
While the preceding text sets forth a detailed description of numerous different embodiments of the invention, it should be understood that the legal scope of the invention is defined by the words of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment of the invention since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims defining the invention.
