Abstract: A combination umbrella and gazebo that can be used as an umbrella or a gazebo. The combination includes a frame, a canopy, and a side. The canopy is affixed to the frame and has an open position and a closed position. The side is affixed to the canopy and has an extended position in which the combination functions as the gazebo and a retracted position in which the combination functions as the umbrella. And, the side achieves its extended and retracted positions by turning a crank which causes a first cord that is operatively connected to eight second cords which are operatively connected to eight third cords which are operatively connected to the side to displace half as much as each of the eight third cords so as to reduce the amount of turning of the crank required to lower and raise the side.

Abstract: A frame for a bimini cover for a deck of a water craft.

The frame has first and second support members each of which have a first end fixed to the deck and a second end fixed to the first end frame to define first triangular members to hold the first end frame in a fixed position with respect to the deck. The second end frame is moved from a closed position to an opened position to selectively extend a canopy over the deck. First and second strut members are secured to the first end frame and joined to the second end frame to define second triangular members. The strut members are adjustable after being joined to the second end frame to hold the second end frame at a fixed arcuate distance from the first end frame while maintaining a predetermined tension on the canopy.

Abstract: The present invention features a tent roof construction having a double, hollow, tubular joint. Vertical and side tubes that make up the tent-frame attach to this tubular joint. The improvement allows the tent-frame to be built quickly and without nuts and bolts (thus, allowing assembly and disassembly without tools) by using a second horizontal support tube, a tube which parallels the horizontal support tube of previous roof constructions. This second tube is located directly below the first horizontal support tube, thus allowing the canvas roof cover to be pulled over the first horizontal support tube and attached to the second horizontal support tube. Thus, the roof cover extends over the end of the roof frame and down the sides of the tent. The side covers extend up the inside of the tent-frame and attach to the first horizontal support tube, creating an overlap between the roof and side covers.

Abstract: A portable bivouac shelter (10) is provided having an end pole (48) retaining on the top sheet (12) through a tunnel (46) for holding the top sheet (12) in a taught and semi-circular configuration. This permits the top sheet (12) to be held away from the bottom sheet (14) in an open configuration for enhanced ventilation. A top pole (54) is also provided across the top sheet 12 near the head end (20). The top pole (54) cooperates with the flexible end pole (48) to form a sloped roof over a user's head and to hold the top and bottom sheets (12) and (14) in a selected degree of an open configuration. Optional mounting snaps (62) in the interior (24) of the enclosure (18) enable a user to reconfigure the opening (26) without leaving the interior (24) of the shelter (10). The shelter (10) thus provides enhanced ventilation while the sloped roof formed by the top pole (54) prevents the entry of precipitation into the enclosure (18). Optional mosquito netting (32) is zippered on the interior of the opening (26).
