  • Patent number: 11813761
    Abstract: A handle bending razor includes a grip portion, a razor head, and a head coupling portion. The razor head has a blade body, a blade assembly body, a connecting portion, and an elastic support body. The handle bending razor includes a switching mechanism which can change an angle formed by a contact surface and an up-down direction and, when an external force is not applied, switches between a first state in which a neutral angle formed by the contact surface and the up-down direction is a first angle, and the contact surface and the up-down direction become substantially parallel and a second state in which the neutral angle is a second angle larger than the first angle. In the second state, when the external force is applied, the blade assembly body is tiltable to a position where the contact surface and the up-down direction become substantially perpendicular.

  • Patent number: 11597110
    Abstract: A handle for a shaver includes a handle body extending along a longitudinal axis of the handle; a connector for attaching a cartridge to the handle rotatable with respect to the handle body around a rotational axis perpendicular to the longitudinal axis; and an elastic tongue extending parallel with the longitudinal axis of the handle, when in a neutral position. The connector includes a cartridge end and a tongue end opposite to the cartridge end, the cartridge end of the connector being adapted to engage with the cartridge. The elastic tongue includes a first end and a second end. The first end of the elastic tongue is fixedly attached to or integral with the handle body. As the connector rotates the second end flexes towards a first extreme flexed position or a second extreme flexed position, the flexed elastic tongue biases the connector towards the rest position.

  • Publication number: 20040231160
    Abstract: A dry shaver has a cradle head carrying shaving units as well as a motor for driving the shaving units. The cradle head is supported to a hand grip such that it is allowed to swivel about at least one swivel axis parallel to a thickness direction of the hand grip. At least one portion of the motor projects upwardly of the swivel axis, whereby the cradle head is given overall mass center which is located upwardly of the swivel axis with respect to the height axis of the hand grip. Accordingly, the motor of heavy nature can be best utilized to locate the overall mass center of the cradle head above the swivel axis for generating a torque acting to swivel the cradle head from a neutral position about the swivel axis when the hand grip is held upright.

  • Patent number: 6725550
    Abstract: A shaver apparatus including a handle, a head connected to the head, a first blade connected to the head and extending transverse to the handle, a second blade connected to the head in parallel relationship to the first blade, and a third blade connected to the head in parallel relationship to the second blade. The third blade extends perpendicular to the head. The first and second blades extend at an acute angle relative a the plane of the head. A spring is connected to each of the blades so as to urge the blades to a desired angle. A spring is also connected to the head and to the handle so as to urge the head to a desired angle with respect to the handle. The head is adjustably angularly connected to the handle.

  • Patent number: 6560881
    Abstract: A shaving razor has a blade carrier, which may be part of a replaceable blade cartridge, pivotally supported by a main component or handle assembly, the main component and the blade carrier having cooperating convex and concave arcuate bearing surfaces whereby the carrier is movable about the pivot axis by sliding movement of the convex and concave bearing surfaces over one another, and a spring mechanism both holds the convex and concave bearing surfaces in engagement with one another and resiliently biases the carrier in one direction about the pivot axis toward a limit position.

  • Patent number: 5953824
    Abstract: Razors adapted to support a razor head during shaving while permitting the razor head to move relative to the razor in response to forces encountered during shaving. Preferred embodiments allow a razor head to swivel and also to pivot about an axis normal to a central axis of the razor and normal to an imaginary axis defined by the points of attachment of the razor to a razor head. According to another aspect, an engagement arm comprises a novel slot for controlling the movement of the engagement during shaving, as well as during loading/unloading of a razor head. Embodiments of this invention enable the razor head to maintain optimum shave relation with the skin regardless of the angular differences between the cartridge head, razor handle/grip and shaving motion during shaving.

  • Patent number: 5787594
    Abstract: The detailed shaving device includes a spring-mounted, infinitely-positionable, rotating razor blade with a full 360-degree range of motion which is attached to a handle having an angular offset for improved grip. The shaving device allows the user to lock and release the razor blade from its angular position relative to the handle and includes a knob for adjusting the rotation of the blade. The characteristics of spring mounting, infinite position adjustment, and razor blade rotation allow the user to accurately shave difficult to reach areas of the body.
