A lift and extraction system for an automatic swimming pool cleaner may facilitate removal from the of the automatic swimming pool cleaner from a swimming pool, deployment of the automatic swimming pool cleaner into a swimming pool, and/or storage of the automatic swimming pool cleaner outside of the swimming pool. The lift and extraction systems may include a frame, motive elements, and one or more engagement features for selectively engaging and positioning the automatic swimming pool cleaner relative to the frame.

A collapsible support structure includes at least a horizontal support structure, a vertical support structure, and an axle assembly. In use, the collapsible support structure may be folded/unfolded between a deployed configuration, in which the collapsible support structure may be capable of rolling along a support surface to transport items, and a stowed/storage position, in which the collapsible support structure is collapsed in a compact geometry for storage. The axle assembly enables removal of the wheels from the axle for storage of the collapsible support structure. The axle may be repositionable between a deployed position and a storage position. The axle may be equipped with a retainer unit that retains the axle in the deployed position.

A cart/trailer, yoke mechanism, and hitch mechanism are disclosed. The cart/trailer could be an assembly for moving and transporting objects comprising a tow bar (synonymous herein with a handle or kickstand); a variable-positioning yoke assembly for facilitating the placement of the tow bar into positions of a towbar, handle, or kickstand; and a main structure within which equipment such as sporting accessories may be placed for transport for moving and transporting objects. The coupling device could include a main body with an inner surface, and a pair of opposing flanges extending downwardly and substantially perpendicularly away from the main body for facilitating the positioning of the yoke in variable positions. The hitch mechanism could include a hitch and interface with receiver and hitch portions for facilitating the hitching of the cart/trailer to a mobility device.

A hand truck having a frame with first and second ends and a handle adjacent the first end and a platform extending from the second end. Wheels adjacent the second end support the frame and platform for rolling movement. A lever member with first end pivotally connected to the frame at the first end and second free end. A position stabilizing member is pivotally connected to each side of the frame proximate the second end with each shoe assembly being pivotal to a support position extending below a respective wheel. The free end of the lever member is positioned against a surface and the frame pivoted thereabout with the shoe portion of each shoe assembly moving to the support position. An automatic braking system prevents unwanted downward movement. A repositioned lever member and multiple commonly hinged lever members allow for full stair lifting and elimination of the position stabilizing member.

A hand truck assembly for lifting and moving heavy loads includes a plate, which is engaged to and which extends from a lower end of a rod. The plate is positionable on a surface beneath a load with the rod extending upwardly. A user can grasp and pull the rod, proximate to an upper end of the rod. A rearward frame is engaged to and extends from the rod proximate to the lower end so that the rearward frame is opposingly positioned on the rod relative to the plate. An axle is rotationally engaged to the rearward frame and is perpendicular to the rod. A pair of wheels is engaged singly to opposed ends of the axle. A lower limit of the pair of wheels is coplanar with the plate. The load is lifted from the surface by pulling on the rod to pivot the plate around the axle.

A holding device, capable of floating, is removably attachable to a gunwale of a boat or other object and is comprised of a basket member having a base frame for holding cargo. A vertically oriented vertical frame member extends upwardly from the base frame and together with a hook assembly, forms a variable width J-shaped hook to hook the device onto the boat. A pair of wheels is attached to the basket member with their distance relative to the base frame being variable. The wheels allow ground transport of the device and also to provide a support for a lower portion of the device against the side of the boat. The wheels also create a pair of flotation members should the device become dropped into the water. A height adjustable handle can be used to pull the device on the ground surface.
