Abstract: A ventilation fan that functions as a wheel for movements. The generally cylindrical fan housing is pivotally coupled to a triangular handle. The handle may be manually grasped to roll the fan towards an operative position. The handle may be positioned in a temporary storage position, and an inverted, operative position where the drum is elevated for stable use. The drum-shaped fan rolls on its own, and the fan radius becomes the rolling radius. The preferred handle is attached to suitable bearings secured to the guards at the center of each side of the fan. When the destination is reached, the handle is deployed upside-down to function as a support stand, and the fan remains in a stable orientation without moving or shifting its position during operation.

Abstract: A device for mooring small boats includes a rigid tubular sleeve with outwardly flared ends. A stretch cord located in the sleeve has attaching members in the form of hooks or the like at each end which extend at least partially outside the associated sleeve end. To moor a boat, one hook is pulled outwardly, stretching the cord, and fastened to a boat rail or cleat. The other hook is similarly fastened to a ring or eye-bolt on the dock. The stretch cord urges the hooks toward the sleeve so that the hooks and flared sleeve ends cooperate to form grips; and the sleeve acts as a spacer to space the boat from the dock.
