Title:
RETRACTABLE WHEEL FOR BOAT LIFT AND OTHER STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2010/090829
Kind Code:
A3
Abstract:
An assembly for attaching to a boat lift 12 includes a boat lift 12 attachment mechanism 70 for attaching to the boat lift 12; an outer support 24; an inner support 26 slidable within an interior of the outer support 24; a tire 22 attached to the inner support 26; and a stop member 82 extending from the outer support 24 to engage the tire 22 when the inner support 26 is retracted into the outer support 24. An outer surface of the inner support 26 is configured to be mateable with an inner surface of the outer support 24, thereby preventing rotation therein while permitting longitudinal movement with respect to the outer support 24. In another aspect, an assembly includes an axle 54 attached to the inner support 26 for the attachment of a ground engaging member. A method of leveling a boat lift 12 includes causing substantially vertical movements of first and second portions of the boat lift 12 until the boat lift 12 is horizontally level.
