  • Patent number: 10835009
    Abstract: A weaving tool has a first part and a second part, in which a first end of the first part is connected to a first end of the second part by a hinge. The first part has a first comb portion with first teeth extending away from the hinge, and the second part comprises a second comb portion with second teeth extending away from the hinge. The first part and the second part are movable about an axis of the hinge between a first position in which the first comb portion and the second comb portion are substantially parallel, and a second position in which the first comb portion and the second comb portion are displaced from one another about the axis.

    Abstract: There is disclosed a comb. The comb has an upper or a basic part and a number of teeth attached to and pointing out from the upper or basic part, wherein the outer or free end of at least a portion of the teeth forms two curved shapes or curvatures for the touch of a scalp. The first curvature has a radius of curvature substantially perpendicular to the longitudinal direction of the teeth, and the second curvature is curved outwards in relation to the upper or basic part. The radius of curvature of the first curvature may be in the range of 3-14 cm.

  • Publication number: 20090065015
    Abstract: The spring hair comb consisted of the handle and the compression spring. The teeth of the comb are made of the coils of the compression spring. The thickness and spaces of the teeth depend on the size of the compression spring. This comb combs through hair smoothly with minimal friction and no pain to the scalp due to its round coils and its larger contact surface than the small and pointed teeth of other combs.

  • Patent number: 6098633
    Abstract: A hair comb has a handle (1) having an arcuate portion (2) and a finger grip portion (3). The handle is connected to a spine (4) into which are secured two parallel planes of rows of teeth (10). The teeth (10) are spaced so that a first row of teeth (11) are more widely spaced than a second row of teeth (12), the teeth having a cylindrical cross-section and rounded end tips (13). The spacing between the rows of teeth are such that as the teeth move through hair, the first row perform a first coarse combing for head lice, nits and eggs and the second row of teeth perform a more fine filtering of head lice, nits and eggs.

  • Patent number: 5771904
    Abstract: The invention is directed to bristles for a hairbrush, in particular for employment in an appliance for personal use as, for example, a curling iron, a curling brush, a hair dryer or the like, including a bristle base (3) and a bristle head (5). In this arrangement, the bristle base (3) is adapted to be fastened to a bristle supporting structure (7). The bristles (1) include at least two sections (9, 11) with cross-sectional areas of different sizes. A section with an increased cross-sectional area (11) adjoins the bristle base (3) having a reduced cross-sectional area, so that the bristle (1) is provided with a neck portion (17) between the bristle supporting structure (7) and the section with the increased cross-sectional area (11).

  • Patent number: 4807652
    Abstract: A comb for removing lice and nits from the hair is formed by a base and a plurality of teeth extending from the base in substantially the same direction. The longitudinal axis of each tooth is parallel to the longitudinal axis of each other tooth. Each tooth has a polygonal cross sectional shape such as in the form of a modified triangle. The cross sectional dimensions of each tooth enlarge from the free end of each tooth toward the base so that the spacing between adjacent teeth narrows toward the base. The facing edges of adjacent teeth interact with each other to capture lice and nits therebetween. A rib is provided longitudinally along one of the faces of each tooth.
