  • Patent number: 8881334
    Abstract: In one particular embodiment, a basting device incorporates a handle body, having a handle portion and a working portion, and a bristle cartridge removably coupled to the working portion of the handle body. The bristle cartridge has a set of first bristles projecting outwardly from the cartridge in a first direction and a set of second bristles projecting outwardly from the cartridge in a second direction different from the first direction. At least one of the first and second bristles has a proximal end and a distal end, the proximal end being attached to the bristle cartridge and the distal end having a slit therein extending from the distal end toward the proximal end. The slit has a width sized to cause fluid to be drawn into the slit through capillary action when the distal end of the bristle is submerged in the fluid.

    Abstract: An ultra-thin folding bristle hairbrush, capable of being operated with one hand, suitable for back-pocket storage. A base enclosure comprising a plurality of spaced transverse bristle bars, each bristle bar pivotally mounted within the base enclosure. At one end, the base enclosure is pivotally attached to a handle member. A kinematical linkage assembly adjoins the handle with the plurality of bristle bars whereby the opening and closing motion of the handle results in a synchronized articulation of the bristles from a stowed, generally horizontal, position, to a generally vertical position of use. The linkage lends itself to contouring the base enclosure and handle for ergonomic consideration such as back-pocket storage. The handle can also operate as a cover element. A unique one-handed “switchblade” action can be employed to flip open the brush, installing the bristles into their position of use.

    Abstract: In the case of hair brushes the arcuately shaped bristle members of which are studded with bristles, mounted in the side walls of a housing being U-shaped in cross section, are arranged in a plurality adjacently and with a distance from one another and are pivotable by means of a slide guided in the housing below these bristle members from a position of non-use into a position of use, this pivoting into the position of use and back into the position of non-use is complicated and time-consuming.This disadvantage is eliminated in that the slide has at its longitudinal edges edge cutouts facing one another, the bristle members resting between these edge cutouts on the slide in such a manner so as to be secured against unintended pivot movement. The slide can be approached with its edge cutouts to the ends of the bristle members by sliding movement in such a manner that the bristle members, by a sliding pressure by hand on the bristles, obliquely engage in the edge cutouts in the position of non-use.

  • Patent number: 4321723
    Abstract: A compact hair brush particularly suitable for traveling. A flat housing is provided with a plurality of rows of transversely mounted bristles. Each row of bristles is individually mounted on a pivoted bar. A longitudinal operating rod pivotally connects to each bar above the pivot point. Longitudinal movement of the bar causes a pivotal movement of the bars. A manually engageable portion of the rod extends out of the housing for operating the rod. After the housing is opened to expose the bristles, the rod is operated to pivot the bars and cause the bristles to stand up in vertical operating position. The brush is now ready for use. Reversely, the rod is operated to pivot the bars and cause the bristles to lie flat in the housing. This permits closing the substantially flat housing. The construction lends itself to many variations in the housing. The manually engageable rod may be positioned in various portions of the housing depending on the design used.
