1. Field of the Invention
The present invention relates to a hair styling instrument, and more particularly to a grip used for a hair styling instrument.
2. Description of Related Art
Tint (coloring) brushes are commonly used by hair stylists and other hair professionals to apply tinting or coloring to a subject's hair. Tint brushes typically have one end with brushes attached to handle. The handle of the brush is often used to straighten the subject's hair in between use of the brush to apply or spread tinting to the hair. Thus, the handle typically has a smooth surface that allows the handle to move easily through hair. Additionally, the handle may be small in cross-section to move through the hair more easily. The hair stylist or user typically flips the tint brush over to alternate between tinting hair (using the brush) and straightening hair (using the handle). The handle may be difficult to continuously grasp while alternating (flipping) between tinting and straightening hair because of the smoothness and/or size of the handle. Additionally, the stylist typically flips the tint brush with only one hand as the stylist's other hand is used for other uses such as holding the hair. Using only one hand increases the need for a secure grasp of the tint brush while flipping the tint brush. Thus, there is a need for devices and/or methods to more securely grasp the tint brush, especially during flipping of the tint brush, without interfering with the use of the tint brush in tinting and/or straightening of hair.
In certain embodiments, a grip for a hair styling instrument includes an opening that allows the grip to be moved onto a handle of a hair styling instrument and coupled to the handle during use. The opening tapers from a larger diameter at a first end of the grip to a smaller diameter at a second end of the grip. The opening of the grip is sized to contact the outer surface of the handle at at least one location along the grip and position the grip at a selected location along the handle when the grip is coupled to the handle. In some embodiments, the opening of the grip is sized such that at least part of the wall of the opening contacts the outer surface of the handle at a selected location along the grip to position the grip at a desired location along the handle when the grip is coupled to the handle during use.
In certain embodiments, a system for coloring and straightening hair includes a hair styling instrument and a grip. The hair styling instrument includes a hair coloring brush head attached to a tapered handle that allows the handle to be used to straighten hair during use. The grip includes an opening that allows the grip to be moved onto the handle of the hair styling instrument and coupled to the handle during use. The opening tapers from a larger diameter at a first end of the grip to a smaller diameter at a second end of the grip. The opening is sized such that the grip is positioned at a selected location along the handle when at least part of the wall of the opening contacts the outer surface of the handle during use.
In some embodiments, the grip includes ridges that allow a user's hand to securely grasp the grip during use. The grip allows a hand of a user of the hair styling instrument to securely grasp the hair styling instrument while using the instrument to color and straighten hair.
Features and advantages of the methods and apparatus of the present invention will be more fully appreciated by reference to the following detailed description of presently preferred but nonetheless illustrative embodiments in accordance with the present invention when taken in conjunction with the accompanying drawings in which:
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. The drawings may not be to scale. It should be understood that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but to the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.
In the context of this patent, the term “coupled” means either a direct connection or an indirect connection (e.g., one or more intervening connections) between one or more objects or components.
Brush head 102 may include bristles 106. Bristles 106 may be used to apply or spread hair coloring into human hair. For example, bristles 106 may be used to apply a coloring agent, or other chemicals, to human hair and then spread the coloring agent through the hair. Brush head 102 and bristles 106 may be any type of brush head and bristles known in the art for applying chemicals to human hair.
Handle 104 may be used to operate brush head 102 and bristles 106. For example, handle 104 allows a user of instrument 100 to apply the coloring agent or other chemical to human hair. In certain embodiments, handle 104 is used to straighten or part hair. For example, the end of handle 104 opposite brush head 102 may be used to straighten hair by moving the handle end through the hair.
Handle 104 may have any cross-sectional shape desired or known in the art. For example, handle 104 may have a rectangular, circular, or square cross-sectional shape. In certain embodiments, handle 104 is beveled or tapered along the length of the handle, as shown in
In certain embodiments, handle 104 has a smooth surface that allows the handle to move through the hair more easily. The smoothness of handle 104 may, however, inhibit the user of instrument 100 from securely grasping the handle. Handle 104 may be particularly difficult to securely grasp when flipping instrument 100 in the user's hand. Instrument 100 may be flipped to alternate between using handle 104 to straighten hair and using brush head 102 to apply/spread coloring agent. As the user typically will flip instrument 100 with only one hand and do so in a quick manner so that the other hand remains free for other tasks, a secure and reliable grasp of handle 104 is needed.
In certain embodiments, grip 200 includes ridges 202, as shown in
As shown in
In certain embodiments, as shown in
Because the larger diameter of opening 204 is larger than the end of handle 104, as grip 200 is moved onto handle 104 during use, the grip can be moved onto (e.g., slid onto) the handle until at least part of the inner surface of the grip (at least part of the wall of the opening) contacts the outer surface of the handle and inhibits further movement of the grip onto the handle. Thus, when at least part of the inner surface of grip 200 contacts the outer surface of handle 104, the grip is coupled to the handle. When the inner surface of grip 200 contacts the outer surface of handle 104, the grip may be securely coupled to the handle until the user applies a small amount of force to remove the grip from the handle.
In certain embodiments, the size of opening 204 in grip 200 is selected to position the grip at a selected (desired) location along the length of handle 104. For example, opening 204 may be sized such that grip 200 is positioned at a selected location along handle 104 when at least part of the wall of the opening contacts the outer surface of the handle. In some embodiments, opening 204 is sized to contact the outer surface of handle 104 at at least one location along grip 200 and position the grip at a selected location along the handle when the grip is coupled to the handle. In some embodiments, opening 204 is sized such that at least part of the wall of the opening (the inner surface of grip 200) contacts the outer surface of handle 104 at a selected location along the grip to position the grip at a desired location along the handle when the grip is coupled to the handle.
In certain embodiments, the size of the larger diameter of opening 204 in grip 200 determines the location at which the grip is secured on handle 104. In some embodiments, the size of the smaller diameter of opening 204 in grip 200 determines the location at which the grip is secured on handle 104. In certain embodiments, the size of an intermediate diameter of opening 204 in grip 200 determines the location at which the grip is secured on handle 104. In certain embodiments, the entire wall or substantially the entire wall of opening 204 contacts the outer surface of handle 104 at about the same time when grip 200 is at the selected location along the length of the handle.
When grip 200 is positioned on handle 104 at the selected location, as shown in
