Having Pivotal Connection To Blade Patents (Class 30/527)
  • Patent number: 5787593
    Abstract: The present invention is directed to a razor comprising a handle, a razor blade unit having one or more razor blades which can be connected to the front end of the handle, and a connecting device for connecting the razor blade unit to the handle, such that the shaving results are improved for normal shaves as well as for specific applications like medical pre-operation shave. The razor blade unit of the present invention is mounted such that it can swivel relative to the handle about a swivel axis which intersects the cutting edge of the razor blade.

  • 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.

  • Patent number: 5784790
    Abstract: A cartridge-connecting subassembly for a shaving razor handle including a cartridge connecting structure, a handle connecting structure, and a movable component within the cartridge connecting structure that interacts with a replaceable cartridge when it is connected. The cartridge connecting structure and handle connecting structure have outer side surfaces that mate with inwardly directed surfaces of the cartridge and handle so that the subassembly is substantially covered when it is mounted in the handle and a cartridge is connected. The subassembly has an assembly opening for receiving the movable component during assembly, a cartridge interaction opening through which the component is movable for interaction with the cartridge, and blocking structure that retains the movable component in the subassembly. The movable component is an ejector structure that is separate from the cartridge connecting structure. The subassembly is connected to the handle by staking.

  • Patent number: 5771591
    Abstract: A disposable resilient razor in which the razor includes a handle and a razor head interconnected by a resilient, flexible, reduced diameter area of plastic material of one piece construction with the handle and head to enable universal or global flexible, resilient movement of the razor head in relation to the handle. The flexible, resilient, reduced diameter area connecting the handle to the razor head retains the handle and razor head in normal position until a force is applied to the handle when the razor head is engaged with a skin surface to be shaved. This enables a razor blade having a cutting edge mounted on the razor head to be oriented in parallel, substantially flush relation to the skin surface.

  • Patent number: 5678316
    Abstract: It is an object of the present invention to improve the shave performance of a razor of the above mentioned type by providing a pressure sensitive razor design. In addition the handling is improved. A solution for the above mentioned object is characterized in that the resilient connection is shaped in an arcuate line between the handle and the blade unit and the blade unit can be fixed to the connection such that at least one blade is positioned in a plain that is approximately rectangular to a tangent line of the arcuate line of the connection at an end portion where the blade unit can be fixed.

  • Patent number: 5600887
    Abstract: A flexible, easy-to-rinse razor (10), formed in accordance with the present invention, is provided. The razor includes a blade cartridge (16) having a pair of opposing ends (17), an elongated handle (12), a flexible neck (22) coupled to the handle, and a pair of mounting arms (18) extending from the neck and securing the ends of the blade cartridge. In the preferred embodiment, the flexible neck can be protracted into and retracted from the handle by turning a rotatable cuff (36) coupled to the handle. In yet another embodiment of the present invention, the razor is provided with a flume (28) attached to the flexible neck that is capable of converting a normal circular-shaped water stream into a substantially rectangular-shaped stream and directing the substantially rectangular-shaped stream through the blade cartridge.

  • Patent number: 5560106
    Abstract: A razor structure incorporating a resilient connection between a razor handle and a razor head which enables the razor head to resiliently float in relation to the handle with the floating head being capable of resilient movement in all directions of movement in which the resilient characteristics of movement of the razor head exerts optimum blade pressure against the anatomical skin surface when the blade or blades on the razor head are oriented in optimum relation to the anatomical skin surface being shaved. A plurality of embodiments of the invention are disclosed with all embodiments enabling the razor head to move against a resilient bias, provided by a resilient, flexible body or component, in all directions or in the X, Y and Z planes.
