  • Patent number: 5193528
    Abstract: A hand-held extensible vibratory massager comprises a hand grip to be grasped by a hand of a user, a self-contained vibration applicator generating a vibratory massaging motion. An arcuately extensible arm interconnects the hand grip and the applicator so that the applicator is movable along an arcuate path from a normal position adjacent the hand grip to an extended position away therefrom, facilitating to locate the applicator on a portion of the body over an extended range with enhanced operability.

  • Patent number: 4701595
    Abstract: A portable hand-held hair dryer having a housing formed with an elongate front edge portion along the edgewise direction of which is extended an air outlet for discharge of heated air. A hand grip is slidably connected to the front edge portion of the housing for movement therealong in a straight path between a retracted position in which the hand grip overlies the front edge portion to block the air outlet and a projected position in which the hand grip extends outwardly of the housing to be ready for being grasped by the hand of the user after opening the air outlet. A recess is formed in the housing at a portion adjacent to the function of the hand grip in its projected position so as to receive a portion of the user's hand grasping the hand grip. This recess is advantageous for providing a comfortable support of the hair dryer with a minimum projected length of the hand grip. A voltage selection switch is positioned so as to be accessible only when the hand grip is in its retracted position.

  • Patent number: 4565916
    Abstract: An electrically heated hair curling iron has first and second handles pivotally connected at one end for movement toward and away from each other. Supported on the free ends of the handles are an electrically heated rod and a press plate which respectively project outwardly from the free ends. A electric power supply cord is connected to the electrically heated rod by a rotatable connector formed as a protrusion on one of the pivotally connected ends of the handles on the opposite side of the handles from the free ends thereof. The axis of rotation of the connector is coaxial with the centerline between the two handles and is in the same plane as the pivotal connection between the handles. Thus the iron can be easily rotated without twisting the power cord. The iron has an adjustment to regulate the opening angle of the handles and a releasable lock for securing the handles together in closed condition.

  • Patent number: 4556782
    Abstract: A foldable hair dryer of the hand-held type which includes a housing incorporating an electrically operated means for producing a flow of heated air, a hand grip pivotally attached to the housing, and a power cord extending from the housing. The hand grip is rotatable to a operational position where it extends outwardly from the housing, and to a folded position where it is folded on a part of periphery of the housing. Formed along the periphery of the housing is a first groove which cooperates, when the hand grip is in the folded position, with the second groove formed in the hand grip to define a peripheral channel extending across the housing and the folded hand grip. The power cord can be received in the peripheral channel thus formed and be wound up along the entire periphery of the hair dryer when the hand grip is brought in the folded position.
