  • Patent number: 4691470
    Abstract: A tackle box has superposed interlinked trays which are stacked inside of the box when it is closed and which are moved into a staggered opened out configuration by cantilever linkages when the box is opened. The trays are made of a clear plastic material capable of transmitting light by edge lighting. The uppermost and lowermost trays have central compartments receiving respective self-contained flashlight-type light fittings each with a light bulb received in a socket formed in the base wall of the respective tray. When activated, the respective light bulbs light the respective trays be edge lighting. The light fittings have plunger-type switches projecting upwardly for actuation by the tackle box lid and the intermediate tray respectively so that the lighting system is automatically actuated when the box is opened. The switches can be permanently positioned in an off condition for daylight use. The light fittings may be removed for independent use as flashlights.

  • Patent number: 4060864
    Abstract: A small boat or the like comprising a flotation chamber defined at its gunwale by a first member, preferably integral with the sides of the hull extending upwardly and defining a first lip at its terminal end portion, a second member or cover secured at its bottom portion to the hull and extending inwardly of the first member with its upper end portion extending over the first member and including a second lip, and a connecting device resiliently engaging the first and second lips with each other to secure flotation material in the form of a block of expanded polystyrene or the like within the flotation chamber. The connecting device can be a separate element pressing the lips of the first and second members against each other or can be a resilient portion of one of the members normally biasing the lips into engagement. A rub rail is defined at the upper end of the flotation chamber and can be formed either by a separate connecting member or by a portion of one of the other members.

  • Patent number: 4060865
    Abstract: A small boat or the like comprising a flotation chamber defined at its gunwale by a first member, preferably integral with the sides of the hull extending upwardly and defining an upper end portion which may include a reverted first member lip, a second member or cover secured at its bottom portion to the hull, the major portion of which is spaced laterally from the first member with its upper end portion extending over the first member and including a reverted second member lip, and a connecting device resiliently engaging the upper end portion or first member lip with the second member lip to secure a flotation material in the form of a block of expanded polystyrene or the like within the flotation chamber. The connecting device can be a separate element pressing the lip of the first and second members against each other or can be a resilient portion of one of the members normally biasing the two members into engagement.

  • Patent number: 4045889
    Abstract: A snowshoe substantially entirely formed of plastic and including a peripheral rib defining front, central and rear sections, the rear and central sections being substantially flat and the front section extending upwardly in a smooth fashion from the central section to define an upturned tip portion, the rear section including latticework forming openings to permit passage of snow, the central section including means for securing a foot harness to the snowshoe with central portions of the central section adapted to support the foot of a user and including latticework to preclude trapping of snow between the foot of the user and the uppersurface of the snowshoe, portions on both sides of the central portion being substantially continuous to preclude passage of snow and provide additional flotation to the snowshoe. An integral tail may be defined on the snowshoe and tip portion may be substantially continuous to preclude catching on branches.
