Abstract: An improved convertible cart can be converted from a hand truck to a platform by a simple pull of a spring loaded adjustment arm. The convertible cart has reversible wire retainers. When the edge of the wire retainer is facing upward, it prevents an object being carried from shifting sideways off of the rails. The wire retainers can also be flipped downwards to allow an oversized object to be carried flat and extend outside the retaining rails. The toe plate of the cart can be used as a seat with a pad that can be attached as a weeding pad either from the seated or kneeling position. The cart's handle frame can be sleeves into its base frame so that entire cart can be packed tightly within the tub to allow the tub to be the principal storage and delivery means for display, sale and shipment.

Abstract: A wheelbarrow or cart with a forwardly located wheel and two rearwardly located stand guards having first and second tubular support legs adapted to be attached to the stand guards, and first and second tubular leg members having outside diameters slidably coupled in telescoping arrangement with the inside diameters of the first and second tubular support legs. A first twist clamp means is coupled to frictionally engage and selectively lock the first tubular support leg relative to the first tubular leg member to set the total length of the first telescoping tubes and a second twist clamp means coupled to frictionally engage and selectively lock the second tubular support leg relative to the second tubular leg member to set the total length of the second telescoping tubes.

Abstract: The locking nut and bolt system utilizes a bolt with thread having a plurality of notches generally longitudinally spaced in a predetermined pattern. Each notch has a lock face and an opposing slope. The locking unit carries one or more tines. The tine has a distal tine end adapted to latch onto the lock face of the notch on the bolt and, when the distal tine end is not disposed in one or more notches, the tine end moves on the bolt thread crest. When the distal tine end is in the notch or notches, the lock face of the notch prevents counter-rotational movement of the bolt with respect to the nut when the distal tine end abuts the lock face. The locking unit supports the tine and may be cylindrical, rectangular or on a perpendicular support face normal to a radial plane through the axial centerline of the nut thread. The locking unit may be on a nut insert or may be carried on the leg of a U, J or S-shaped clip. The locking unit may be recessed as a blind hole.

Abstract: A wheelbarrow that incorporates a stand coupled to a tub, a handle at the distal end of the wheelbarrow, and a wheel mount at the proximal end of the wheelbarrow. A wheel is rotatably coupled to the wheel mount and comprises a rim surrounded by a non-pneumatic tire. The tire has a mounting region and an expanded region. The axial width of the expanded region is substantially greater than the axial width of the mounting region and the tire has a relatively flat tread surface.

Abstract: A wheelbarrow bumper for a wheelbarrow that has a bumper plate that spans distal ends of a plurality of wheelbarrow handles and a plurality of sleeves that extend in a direction relative to the bumper plate such that the sleeves comprise an angle of orientation that is non-perpendicular relative to the bumper plate. Upon alignment of the plurality of wheelbarrow handles with a corresponding sleeve and coupling of the plurality of wheelbarrow handles to at least one other wheelbarrow element, such as a wheelbarrow stand, tub, or tire, the plurality of sleeves are inhibited from moving in a proximal or distal direction relative to the wheelbarrow.

Abstract: A wheelbarrow rack is disclosed generally comprising first and second rack stands, first and second upright posts connected to the first and the second rack stands respectively, multiple wheelbarrow support braces pivotally attached between the upright posts, and multiple stopper ledges attached to upright posts below the wheelbarrow support braces. In some embodiment, the wheelbarrow rack includes a spare wheel holding assembly attached to the rack. The method for conserving space while displaying or storing wheelbarrows is provided. Also, a method is provided for easy removal of the unwanted rainwater from wheelbarrows collected while displaying or storing wheelbarrows outside.

Abstract: A wheelbarrow bumper for a wheelbarrow having a frame, a bin, and a wheel, the wheelbarrow bumper includes: a curved plate having a convexly curved outer surface and an inner surface; and, a first and a second side support members having a width and extending transversely from the curved plate, the first and the second support members each including an engaging portion adapted to connect to the frame of the wheelbarrow. The curved plate and the support members, as a whole, define a generally bracket-like cross-sectional configuration. Each engaging portion of the support members preferably includes an opening for receiving a clamping member to connect to the frame of the wheelbarrow.
