  • Patent number: 4471505
    Abstract: A toothbrush (1) comprising a plurality of T-shaped bristles (5) is described. Each of the bristles (5) comprises an elongated cleansing head (11,22) terminated at each end by rounded ends (13,27) and having between the ends a plurality of cleansing elements (12,24). The rounded ends (13,27) are provided for presenting a nonabrasive surface to the subgingival surfaces (17) surrounding a tooth when the cleansing surface of the cleansing head (11,22) is moved across the surface of the tooth during cleansing of the tooth. In one embodiment, the cleansing elements (12,24) are conically shaped members (12) terminated by a relatively sharp tip. In another embodiment of the invention the cleansing elements (12,24) comprise parallel, substantially rectangular members (24) terminated by a relatively sharp edge (25).

  • Patent number: 4465295
    Abstract: A ski binding having a portion which holds the ski boot and moves relative to a ski over a predetermined distance and in predetermined directions, which may be perpendicular to each other, relative to the ski. The binding employs a mechanical or electromechanical transducer for sensing the skier's movement which triggers a relative movement of the binding. Guides are provided to direct and limit the movement of the binding. A power activator for the binding is generally disposed between the sole of the ski boot and the ski and utilizes relatively minor movements of the ski boot sole, or electrical power, to move the binding portion relative to the ski.

  • Patent number: 4447968
    Abstract: A shoe such as a running shoe is disclosed which fits comfortably on the foot of the wearer during most times and which includes a sensor such as a bar movably attached to the shoe for increasing the tightness of the fit when the foot is moved relative to the lower leg in a plurality of directions from a normal position to positions relative in which greater forces are expected to be exerted by the user. Typically, the increase in forces is achieved by placing a movable insert in the shoe which is connected with the sensor via a cable. In a simplified form, the sensor is constructed so as to tighten a portion of the shoe against the foot to increase tightness of the fit.

  • Patent number: 4395055
    Abstract: A ski release side clamping binding with hinged jaw members is described. In the binding there is provided a housing. In the interior of the housing there is movably mounted a pair of housing mounted plate members. To each of the housing mounted plate members there is pivotably attached a jaw member. Coupled to the jaw member is a resilient clamping member. The resilient clamping means is provided for resiliently releasably clamping a ski boot between the jaw members. In use, the jaw members are free to pivot downwardly when the jaw members have moved outwardly a specified distance from the housing against the restraining force of the resilient clamping member. The downward pivoting of the jaw members is provided for removing a potential obstruction to the movement of the ski boot by the jaw members during a rotational release and the like.

  • Patent number: 4382342
    Abstract: A dynamic internal fitting system for a ski boot having a lower shell member and an upper cuff member. Interior of the ski boot there is provided a pair of strap members for engaging the lateral and dorsal aspects of a foot. One end of the strap members is attached to the sole of the ski boot. The opposite end of the strap members is connected to one end of a cable by means of a pivotable linking member. The cable extends from the linking member and is connected at its opposite end to a pulley. The pulley is releasably coupled to the cuff member and means are provided for manually selectively adjusting the length of the cable wrapped about the pulley. During skiing maneuvers, as the position of the foot changes in the boot, the linking member pivots for dynamically adjusting the tension applied to and the position of the strap members relative to the foot engaged thereby. Additionally, as the cuff member pivots relative to the shell member, the pulley rotates with the cuff member.
