  • Patent number: 9394038
    Abstract: This invention provides a paddle retainer for stand-up paddleboards. There are two basic embodiments of the idea: a plug with a paddle-retaining slit that can be attached wherever the user wishes to attach it on the SUP, and a paddle-retaining slit built into the kicktail of the SUP. With both embodiments, the tip of the paddle is held within the slit portion by friction, such that SUP users can easily “store” their paddles in a vertical position while engaging in activities such as fishing that require them to store their paddles, and then easily retrieve their paddles without bending over to pick them up. The plug optionally has one or more holes into which fishing rods can be removably secured.

  • Patent number: 4822309
    Abstract: The invention comprises generally square buoyant cushions. A separate fabric skirt is attached to each side of each cushion. Each skirt has fastening means so the skirts on one cushion can be fastened to the skirts on another cushion. If the cushions are stacked one on top of another, and the skirts of the stacked cushions are connected together, the skirts are sufficiently long so the buoyant compartment formed by the facing surfaces of the cushions and the connected skirts of the cushions will have sufficient volume for storing emergency supplies. In another configuration the skirts on the cushions can be connected together in side by side relationship to form a chain of buoyant cushions or a raft which can support a number of people so they will not drift apart in the water.

  • Patent number: 4690091
    Abstract: A securing arrangement so executed as to be tripped for release on actuation for the purpose of changing the state of an attached item of equipment. It is so executed as to secure the equipment by means of a loadable link (8) in a securing position. The equipment can be released by means of a tripping arrangement (36, 37, 42) by breaking the link by the actuation of an actuating arrangement (20, 32) by means of a specific factor such as a change in pressure. The link consists of a device which is capable of being cut through, such as a cable (8). The tripping arrangement comprises a blade (36, 37) provided with an edge so arranged as to be moved by the effect of the force of a tensioned spring (42) into a position in which the cable is cut through. The actuating arrangement (20, 32) is so arranged as to hold the blade in its first position by means of a locking arrangement (26), and as to release the blade so that it will adopt its second position upon actuation by means of said factor.

  • Patent number: 4662851
    Abstract: A swim float constructed of a plurality of hinged sections. Core blocks are hingedly interconnected by upper and lower flexible layers. Sidewalls of adjacent flexible layers are bevelled so that the skin of a user will not be pinched therebetween. The hinges alternatingly are formed by the upper and lower flexible layers so that the swim float flexes and follows the contour of waves.

  • Patent number: 4595374
    Abstract: A raft inflation valve, which is actuated by pulling a detachable cable connected to one end of a piston, thereby allowing inflation gas to flow from an attached pressure vessel into an inflatable raft includes a valve body having an inlet, an outlet, an internal cylinder open at one end to the valve outlet, and an inlet passage leading from the valve inlet to and intersecting with the midsection of the internal cylinder. A double-ended piston with O-ring seals on both ends is positioned in the internal cylinder so that one end blocks the passage to the outlet. In this position (valve closed) the O-ring seals are on opposite sides of the intersection of the inlet passage which results in a balancing of the gas pressure forces acting on the piston, thereby allowing the piston to be moved (for actuation) by simply overcoming the O-ring drag on the internal cylinder wall. This results in a low actuation force that is only remotely related to the operating pressure of the inflation system.

  • Patent number: 4516943
    Abstract: A raft for a rapid flow water course amusement ride having a generally circular shaped hull fabricated in two sections with a surrounding floatation bumper and separate redundant floatation material in the bottom of the hull. A multiplicity of inwardly facing high-backed seats are disposed around the inner periphery of the hull with a circular hand-hold in the center. The circular construction and seat distribution and arrangement, coupled with the redundant floatation feature, provides a stable and safe floatation device which is especially adapted to endure abuse from collisions with the water course banks and obstructions disposed in the water course while carrying a plurality of raft riders.

  • Patent number: 4409921
    Abstract: A floating platform assembly designed to provide a stable work surface within cylindrical, vertically upward closed vessels which have axially centered obstructions and limited entry space and which vessels are partially filled with a liquid. The platform floats on a plurality of pontoons and includes an annular platform on which persons inspecting the interior of the vessel can stand. The annular configuration of the platform allows it to be assembled within the vessel around the central obstruction. The platform is modular and is assembled in the vessel from a plurality of identical sections. After the inspection of the vessel interior, the platform is disassembled and removed from the vessel through the limited entry space.
