Patent number: 4690091Abstract: 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.Type: GrantFiled: March 18, 1986Date of Patent: September 1, 1987Assignee: Mats HermanssonInventor: Sven-Erik Persbeck

Patent number: 4662851Abstract: 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.Type: GrantFiled: July 9, 1985Date of Patent: May 5, 1987Assignee: Packaging Industries Group, Inc.Inventor: John K. Foster

Patent number: 4650432Abstract: A plurality of rod elements, an inflatable mattress and a cover are configured so that they can be assembled to form a stable raft having good flotation characteristics for supporting an adult individual while traversing a body of water. The components used to form the raft can be reassembled to form a tent. The components can also be disassembled and packaged into a compact, lightweight parcel for easy backpacking.Type: GrantFiled: February 21, 1986Date of Patent: March 17, 1987Assignee: AirSamplex CorporationInventor: Cleo L. Sainsbury

Patent number: 4595374Abstract: 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.Type: GrantFiled: April 13, 1983Date of Patent: June 17, 1986Inventor: Lloyd G. Wass

Patent number: 4516943Abstract: 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.Type: GrantFiled: June 24, 1983Date of Patent: May 14, 1985Inventors: Robert Spieldiener, Reinhold Spieldiener, Alfons Saiko

Patent number: 4409921Abstract: 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.Type: GrantFiled: April 8, 1982Date of Patent: October 18, 1983Assignee: Champion International CorporationInventors: James P. Carroll, Paul S. Cary, Johnny A. McCay

Patent number: 4358866Abstract: A kit includes a legless table and a chair having a tubular frame with detachable legs. The table is detachably connectable to the chair. Rigid flotation material encases portions of the tubular frame and buoyantly supports the chair and the table.Type: GrantFiled: October 25, 1979Date of Patent: November 16, 1982Inventor: Roger D. Rhodes
