  • Patent number: 7464716
    Abstract: An electric flossing apparatus comprising a flossing head which is detachably connected to a handle containing a reciprocating drive unit, a non-powered second handle to allow for the increased controllability of two-handed powered flossing and a disposable floss assembly that can be easily be attached to or released from the flossing head and handle. The floss is releasably attached to the flossing head in a manner that allows reciprocating motion to be imparted along the length of the floss no matter which direction that the floss exits the end of the flossing head or the shape of the path it takes. By using both hands for flossing the floss may be pulled straight and tensioned to facilitate insertion between tightly spaced teeth and then wrapped around a tooth to facilitate cleaning of the front, sides, and back of each tooth above, near, or just below the gum line. The reciprocating motion is imparted to the floss whenever the floss is tensioned.

  • Patent number: 5603595
    Abstract: A method and apparatus for separably connecting a first surface to a second surface. The apparatus includes a connecting member provided with a threaded end. A rotatable body threadably engagable with the threaded end is rotatably supported against the first surface for rotation about the threaded end to separably connect the connecting member. The rotatably supported body and the connecting member are restrained from rotation. The connecting member and rotatably supported body further have a selected matching thread geometry such that a tensile load applied to the member when connected with the rotatably supported body is resolved as a torque applied to the rotatably supported body sufficient to urge the body to rotate. When the rotatably supported body is released and allowed to rotate, the threaded member translates and threadably disengages the rotatably supported body to separate the connection.
