  • Patent number: 6267736
    Abstract: Massage apparatus includes a base structure to be supported by the hand of a user. The base structure includes a first section to be positioned proximate a central portion of the hand and a second section to be positioned proximate a distal portion of the hand. The second section of the base structure is hingedly connected to the first section for articulated movement therebetween to correspond to movement of the distal portion of the hand. The base structure is a housing having first and second surfaces; a resilient pad is provided on at least one surface. Flexible members and a lip extend from the base structure to couple the user's hand with the massage apparatus. Drive motors are mounted on the second section to oscillate the base structure in at least two different directions. A controller independently controls the frequency in which the drive motors oscillate the base structure in each direction.

  • Patent number: 5970616
    Abstract: A hair trimmer that includes a main body extending between an upper end portion and a lower end portion and further includes a front side and a rear side. The main body defines a primary longitudinal axis that extends substantially linearly between the upper end portion and the lower end portion. A blade housing is rotatably attached to the upper end of the main body such that the blade housing is rotatable about the primary longitudinal axis with respect to said main body. The blade housing is defined by an attached side and a free side that is opposite to the attached side. An interface plane is defined between the main body and the blade housing. The interface plane extends at an interface angle that is oblique to the primary longitudinal axis. The present hair trimmer further includes a cutting mechanism that is removably seated upon the said free side of the blade housing. The cutting mechanism includes a cutting surface for engaging and severing hair.

  • Patent number: 5937526
    Abstract: An attachment comb for use with a hair clipper that includes a series of teeth with lower peripheral surfaces of a particular curve that are configured for comfortable movement along the surface of a subject's head, and where the teeth are also preferably proportioned in such a manner as to permit the hair to be uniformly trimmed to relatively long lengths of an inch or greater. Specifically, in the present attachment comb, at least one of the teeth preferably includes a widened rib portion that extends along at least a portion of the length of the lower peripheral edge of that tooth. In addition, the lower peripheral surfaces of the teeth are preferably curved into a half-teardrop shape that includes both a concave curved surface and a convex curved surface. Finally, the teeth may be flared outwardly as they extend away from the base portion so that the hair being cut can be directed toward the cutting blades on the hair clipper.
