A hand propelled three wheeled cart for transporting miscellaneous cargo. The basic cart has a single front wheel with two solid rear supports, such as a standard wheelbarrow. The two rear wheels are attached to a lever that is pivotally connected to the lever mounting support brackets. Lifting the handles pries the two rear wheels, into position, elevating the rear cart support legs off the ground. This cam action reduces the operators lifting effort and improves the lateral stability of the cart. Releasing the handles automatically anchors the cart.

A belt-driven attachment system is disclosed. The attachment system includes a mobile power unit with a drive pulley and a power unit interface for connection of an attachment. The attachment includes at least one driven pulley and a first belt guide to maintain the belt aligned with the at least one driven pulley when tension on the belt is released. The attachment also includes an idler pulley and an idler position assembly coupled to the idler pulley. The idler position assembly provides a first position setting for the idler pulley in which tension on the belt is maintained and a second position setting for the idler pulley in which tension on the belt is released. The attachment also includes a second belt guide to maintain the belt aligned with the idler pulley when tension on the belt is released.

A mobile anchor cart assembly includes a cart including a frame defining a front side and a rear side, the front side disposed opposite from the rear side, the frame defining a front foot and a rear foot, the front foot and the rear foot configured to rest upon a ground surface when the cart is in an anchored position, the front foot and the rear foot configured to clear the ground surface when the cart is in a mobile position; at least one tie-off point attached to the frame; at least one handle extending outward from the rear side of the frame, the at least one handle configured to selectively position the cart about and between the anchored position and the mobile position; and an axle assembly mounted on the front side; and a load defining a load center of gravity.

A method of operating a payload-carrying vehicle having two laterally disposed wheels positioned along a central axis is described. The method includes measuring a force applied by a user to the hand truck, where the measured force comprising a direction and a magnitude, and providing torque to each wheel to cause each wheel to rotate in a respective direction as a function of the measured magnitude and direction. The amount of torque provided to each wheel in response to the force from the user is such that the magnitude of measured force applied by the user is not greater than a predetermined threshold value.

The present invention is directed to a medical instrument stroller having a tubular wedge-shaped collapsible frame structure. The frame is having a first frame member and a second frame member, the first frame member is pivotally coupled to the second frame member. A pair of wheels is coupled to the first frame member. A receptacle having a proximal end and a distal end, the proximal end of the receptacle is pivotally coupled to the second frame member while the distal end of the receptacle is coupled to an attachment member. The attachment member is coupled to the first frame member and is configured to allow the receptacle to switch between a horizontal position and a vertical stowed position. An interchangeable toolbox is mounted on the receptacle. A disposable sharps box is mounted to a support member that extends between legs of the second frame member. Additionally, a trash collector bag is coupled to the receptacle.

A pool cue case caddy for carrying and securing a pool cue case includes a frame comprising a pair of parallel bars and a handle. A base is coupled to a bottom end of each of the bars and perpendicularly extends forward to support a pool cue case. A support comprises a pair of legs pivotably coupled to the pair of bars and a foot extending between a distal end of each of the legs. The support has a folded position extending towards the top end of the frame and an alternate extended position with the foot contacting the ground and the legs maintaining the frame in a vertical position. A pair of wheels is coupled adjacent the bottom end of each of the pair of bars.

A hand truck includes a frame that is supported by main wheels and a handle having two side members. Two handle brackets are pivotably mounted on opposite sides of the frame. The handle brackets are arranged for rotation in relation to the frame around a handle rotation axis. The handle brackets slidably receive the side members of the handle so that the handle is able to slide between a first retracted position and a second extended position. The handle is also able to rotate with the handle brackets between first and second rotational positions. A lock mechanism that is mechanically associated with the handle brackets and the handle is able to releasably lock the degree of extension of the handle in at least one position between the retracted and extended positions and is able to lock the rotational position of the handle in at least one rotational position.

A child transport carrier includes an upper frame member having a forward end and a rear end and a rear frame coupled to the upper frame member. The rear frame includes a lower rear frame member, an upper rear frame member having an upper end fixedly coupled to the rear end of the upper frame member, and a first joint assembly coupling the lower rear frame member and the upper rear frame member. The rear frame is configured to fold between an unfolded in-use position and a folded storage position. The upper frame member and the upper rear frame member are fixed relative to each other. The first joint assembly is disposed longitudinally rearward of the forward end of the upper frame member and longitudinally forward of the rear end of the upper frame member in the unfolded in-use position.

Wheeled transport carts are described which are configured for transporting drain cleaning equipment such as drain cleaning machines and drain cleaning cable. The carts include engagement provisions that enable a drain cleaning machine to be affixed to the cart and preclude unintended separation from the cart during use or transport. The engagement provisions also enable the drain cleaning machine to be quickly and easily separated from the cart. Also described are methods of transporting such equipment using the carts. In addition, systems of the cart(s) with various equipment are described.
