  • Patent number: 10464794
    Abstract: An apparatus for grasping a jar and aiding in lid opening includes a base element that may be placed on a surface, and a top housing that is rotatably secured to the base element. A spiral guide element located between the base element and the top housing includes at least one spiral groove. One or more jaw members may be moveably secured to the top housing, and have a protrusion located within the spiral groove(s). The rotation of the top housing in a first direction (with respect to the base element) causes at least one of the jaw members to move radially inward with respect to the axis to engage a base of container. The rotation of the top housing in a second direction causes at least one jaw member to move radially outward with respect to the axis to disengage with the base of the container.

  • Patent number: 8397604
    Abstract: A method of manufacturing a cutting member (6) of a shaver (1) includes the steps of providing a plate-shaped carrier (10), cutting at least one cutting element (9a, 9b) free from the carrier except for a residual connection between a base (15, 23) of the cutting element and the carrier, and bending the cutting element relative to the carrier. The steps of cutting free and bending are performed simultaneously using a tool (11) having a combined punching and bending effect. By using such a tool, the action of cutting free is obtained by a tearing process which does not lead to a free space and a loss of material between the cutting element (9a, 9b) and the carrier (10). As a result, the strength of the carrier is not reduced by such a free space or loss of material.

  • Patent number: 6158125
    Abstract: A cutter assembly for use in a shaver for shaving hair from the skin of a user includes a casing formed with a static blade configuration and a static bearing surface removed from the static blade configuration. Mounted within the casing is a moving cutter, which has a number of blades and a bearing surface formed to complement the static bearing surface. A spring element biases the moving cutter against the casing so that the complementary bearing surface slides against the static bearing surface, this sliding corresponding to a shearing cutting action of the moving blades relative to the static blade configuration. This reduces the frictional heating between the blades. Also described is a static blade configuration in which extended open-ended slots are reinforcement by transverse support ribs.

The plurality of blades have centers through which the rotary shaft extends for rotation therewith, and when rotated by the rotary shaft, the plurality of blades traverse an elliptical path, in a sweeping back and forth motion, by virtue of their incline. The head further includes a sliding trimmer that is slidably mounted in an axial slot in the guard comb, and is operatively connected to a periphery of a blade for axial sweeping back and forth motion as the blade rotate, by virtue of their incline.

  • Patent number: 5675894
    Abstract: Disclosed is a mechanically operated razor which does not require any electric power supply while functioning as a power-driven shaver. The razor mainly includes a housing, a driving mechanism, a transmission mechanism, a top cover, a shaving blade, and a mirror. Repeatedly pushing a push button of the driving mechanism toward the housing causes a rack connected the push button to move inward and to mesh with and rotate a gear of the transmission mechanism. The rotating gear in turn brings other gears of the transmission mechanism and a flywheel to rotate, causing the shaving blade to rotate rapidly for a prolonged time. The rotating flywheel may reduce the times the push button is depressed while prolongs the rotating of the shaving blade, so that the razor functions like an electrically driven razor. A cleaning brush is removably attached to the razor for cleaning the razor after shaving.

  • Patent number: 5621971
    Abstract: A unique, highly effective, electric dry shaver incorporating rotary cutting blades for use by women to effectively, conveniently, and comfortably shave both legs and underarms is achieved by incorporating a blade guard removably mountable to the electric shaver for partially blocking the rotary cutting blades while also smoothing and/or stretching the soft underarm skin. By employing the rotary cutting blade guard of the present invention, the soft, pliable skin typically found in underarms is comfortably smoothed, spread, and/or stretched to prevent any cutting or pinching of the skin by the blades. As a result, a close, comfortable shave is attained, with all of the hair being completed cut, regardless of the contours of the skin surface or the soft, pliable nature of the skin. Furthermore, when the legs are to be shaven, the blade guard is removed thereby fully exposing the side walls of the slotted outer cutter so it can be used in its entirety.

  • Patent number: 4985999
    Abstract: A hand-held clipper for removing entangled fibers from the surface of fabrics has a grip handle with a cutting head. The cutting head comprises a perforated shear foil and cutter blades rotating in shearing engagement with the interior face of the shear foil. The shear foil is curved into a generally semi-cylindrical configuration having a longitudinal axis and define first and second side faces on the opposite sides of a curved top portion. The cutter blade has a cutting edge extending along the longitudinal axis of the shear foil and is driven to rotate in one direction about a rotations axis, which is common to the longitudinal axis of the shear foil, so as to move along the curved shear foil continuously from the first side face toward the second side faces.

  • Patent number: 4884338
    Abstract: An improved cutter head design for powered shavers, resembling the blade configuration of reel type lawnmowers. Elongated blades are mounted at intervals around a rotatable cutter assembly, with the width of the blades oriented radially. The axis of blade rotation is parallel to the skin being shaved. A thin, semi-flexible perforated screen covers part of the cutter assembly. Hair inserted through the screen is cut by the rotating blades against the screen material. This design allowa a toric (barrel-like) head shape, unlike the current reciprocating or rotary types, which require straight or flat shapes, respectively. A toric shape, is convex on two axes, providing a better match for the difficult facial curves at the jaw/neck junction. Difficulty in that area is where many would-be electric shaver users give up and return to the use of razor blades. Self-cleaning and self-sharpening mechanisms are described, which are made practical by this design. These increase convenience, effectiveness, and cutter life.
