摘要： Method and apparatus for an improved cam lock fitting having cooperating double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on a fork shaped inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space thereinbetween.

摘要： Method and apparatus for an improved recreational canopy which may be used with watercraft wherein the canopy is constructed by using a pair of flexible, resilient rod-like members wherein one end of each of the flexible rods is inserted through mating apertures in an upright support member mounted onto the watercraft, or other structure, so that the rods are bowed outwardly and frictionally held in the stanchion. A canopy, which may incorporate solar cell fabric, is attached between the rods so that the canopy generally appears to be in an elongated V-shaped structure which stretches across a portion of the supporting structure, such as a watercraft, between the flexible rods. The upper end of the upright support member may be pivotable and the rod-like members may be disposed in a cap removably disposed on the upper end of the upright support member. A lighting system including an alternative power source being provided on the canopy. Also, a user driven pedal system for providing propulsion to a kayak watercraft is shown which includes a generator driven by the pedal system for providing additional electrical energy for use on the watercraft and for propelling a kayak by either a propeller or flappers.
