    Abstract: A pivotable blade hair clipper and suction collection system having a hair clipper with a handle drive end portion integrally formed to receive a blade assembly pivotable about a stationary axis into at least two cutting positions. The form of the blade assembly functions to enhance an aerodynamic relationship with a suction air channel that extends internally from one end of the clipper handle to the other and allows for the evacuation of clipped hair debris. The clipper unit is integrally designed to allow for the passage of suctioned air and clipped hair debris from the cutting portion of the blade assembly, then through the clipper unit, and then through a highly flexible suction hose into a personal size vacuum hair collection canister for clean and hygienic collection of clipped hair debris. The two cutting positions combine with the form of the blade assembly to create optimum angles for cutting either hair from the head or hair from other body parts such as the chest and back.

    Abstract: Occupational disorders including pain in hand and stiff shoulders to be caused by using scissors, which are giving rise to problems in the barber and beauty industry, can be lessened or prevented. The scissors are highly versatile to be capable of coping with diversity of cutting techniques. In the scissors, the leg of the movable blade can be divided into the ring side leg portion and the blade side leg portion, and the position of the ring to which the thumb is inserted can be adjusted freely by loosening and fastening the connecting screw depending on the size of the hand and the length of the thumb. Further, the leg of the movable blade is provided with a pair of finger-inserting rings, and the leg of the fixed blade is provided with one such ring. With these total three finger-inserting rings, the scissors can be used in a manner totally different from the usage of the conventional scissors to cope with diversified new cutting techniques.

  • Patent number: 6662451
    Abstract: Hedge shears has a pair of hands, a pair of blades and a rotatable connector secured between the handles and the blades. Each handle has a handle drive slot and each blade has a blade drive slot. The rotatable connector consists of two connecting plates. Each connecting plate has an elongated hole defined in the connecting plate and has a transverse abutting plate formed on an edge of the connecting plate adjacent to the transverse abutting plate of the other connecting plate. A pivot hole is defined in each abutting plate, and a shaft passes through the pivot holes. Two shaft hubs hold opposite ends of the shaft, and a pin secured under each hub passes through the drive slots in the handles or the blades. The blades are able to rotate around the shaft and be operated by the handles by moving the shaft longitudinally.

  • 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.
