Abstract: A load transporter includes a wheel unit and a load support coupled to the wheel unit. The wheel unit is configured to allow the load transporter to roll across a surface while the load support supports an object above the surface. The load transporter is configured to change from an upright orientation to a laid-back orientation where the load support lifts the object above the surface for transportation.

Abstract: Disclosed is a weight training device that can be transformed into a hand truck. The device includes a main frame, two first wheels, a second wheel, two first installing tubes, two second installing tubes and two operating parts, wherein the main frame is used for loading at least one heavy object. Each wheel is fitted on the main frame in a rotational manner, so that the main frame can be moved through the rolling of the wheels. Each of the first installing tubes are opposite each other and respectively extends upward. Each of the second installing tubes are opposite each other and respectively extend away from the main frame. Each of the operating parts are opposite each other in the lateral direction and are respectively and selectively configured on each of the first or each of the second installing tubes, so as to shift the operating mode of weight training.

Abstract: A braking apparatus for a hand truck that keeps the hand truck stable while lifting or dropping a load from the hand truck. The braking apparatus includes a lever and clamps for pivotally mounting the lever to an axle of the hand truck, and a recoiling mechanism that allows the lever to switch between a deployed position and a non-interfering position. The operator can press the lever against the floor to prevent the rolling of the hand truck while loading.

Abstract: A hand truck includes a quick release/attach mechanism operating according to a method for quickly and easily exchanging various tools with the hand truck, the quick release/latch mechanism including biased locking pins movably located within tubular frame members integral to the hand truck and proximal holes in the tubular frame members for receiving a projection member of the tool and spaced a predetermined distance from a hangar portion of the tool and wherein the hangar portion may be hung on a crossbar of the tubular frame and then the projection members of the tool may be coupled with and retained by the locking pins of the tubular frame. The arrangement requires no hand tools such as wrenches or screwdrivers, and no external fasteners such as pins or bolts. The geometry of the cross bars on the hand truck allow tool attachments to be captured or releases simply by tilting the hand truck forward or backward. The tool attachments are then locked to the truck by locking rods and pins that operate inside the two main tubes of the hand truck.

Abstract: A hand truck is provided, comprising a frame, a pair of back wheels secured to a first edge of the frame, a nose plate hingedly secured to the first edge of the frame, a telescopic handle hingedly secured to a second edge of the frame opposite the first edge, and a motorized wheel assembly separately connected to the second edge of the frame and to the handle. The hand truck has three configurations: a hand truck configuration whereby the nose plate is in a horizontal position, the frame is in a vertical position, and the handle is extended vertically; a storage configuration whereby the nose plate is in a vertical position, the frame is in a vertical position, and the handle is retracted; and a scooter configuration whereby the nose plate is in a horizontal position, the frame is in a horizontal position, and the handle is extended.

Abstract: A two-wheeled cart is especially adapted for use as a game cart and may be easily towed by a conventional mountain bike. The cart has two interchangeable wheel positions. In the first wheel position the wheels are attached to the frame at opposite lateral sides of the cart and in this position the center of mass of a load carried on the bed of the cart is relatively low. In the second wheel position the wheels are aligned one in front of the other along the direction of travel as the cart is moved; in this position, the bed of the cart is raised to a relatively higher position than the position of the bed when the wheels are in the first wheel position so the center of mass of a load carried on the bed is relatively higher than when the wheels are in the first wheel position.

Abstract: A convertible hand truck includes a primary frame, a secondary frame and a linkage member. The primary frame has a hook member and a pair of wheels rotatably mounted thereon. The secondary frame has at least one caster rotatably mounted thereon. The linkage member has one end pivotally joined to the primary frame, and the other end pivotally joined to the secondary frame. In particular, the primary frame is movable into (a) a hand-truck position, generally parallel to the secondary frame, (b) a reclined-cart-position, generally positioned at a predetermined angle with respect to the secondary frame, and (c) a platform-cart position, generally perpendicular to the secondary frame. And while the primary frame is in the reclined-cart-position or the platform-cart position, the hook member of the primary frame secures the primary frame to the secondary frame, and the pair of wheels of the primary frame cooperates with the caster of the secondary frame to support the primary frame.
