Abstract: A support arm device is taught for the loading and unloading of equipment on and off a truck bed. The support arm functions like a lever and has wheels at one end and connectors at the other end for coupling to the equipment or to a carrier for the equipment. The support arm is easily mechanically adjustable from vertical to horizontal and vice versa. The wheel end of the support arm is lifted onto a truck tailgate, thus creating a desired axis of balance for the equipment to be loaded. A person acting alone and manually loading the equipment onto the truck bed then only has to apply a less vigorous and less awkward lifting force to the opposite end of the equipment to successfully load it into or onto the truck bed. The invention includes combinations of the support arm with a carrier used with the support arm and also a combination with a support member situated vertically atop the rear end of the carrier.

Abstract: A fulcrum and method of use for passage of a hand truck rearward, handles first, over a curb and onto an adjacent raised surface such as a sidewalk. A short pivotable arm attached to rails of the truck is the fulcrum, and is positioned low on the rearward side of the truck to render high leverage. The arm is connected to stop members which limit outward movement of the arm to about a perpendicular angle to the rails. A latch maintains the arm initially outward for the curb climbing process. In use, the truck is first positioned with its rear side facing the curb, the arm in the outward latched position, and with the truck wheels on the lower surface adjacent the curb, and the truck cargo platform facing outward away from the curb. The truck rails are then manually pulled rearward and downward in an arch over the sidewalk to engage the distal end of the arm against the top of the curb.

Abstract: A positive locking arrangement for a retractable leg of a collapsible hand truck. A slide connected to the hand truck front axle is retained within a slot formed in a tab connected to the retractable leg. The slide includes a projection interlocking the tab thereto. To disengage the locked members, the retractable leg must be swung backwardly in a first motion, thus aligning the slot with the projection. In a second motion, the slide is then raised, the projection just passing through the slot, and the slide continues to feed through the tab, coming to a final vertical position parallel to and against the hand truck body. The slide terminates at an angle, thus cooperating with the tab so as to be urged by gravity to a lowermost position, thus favoring engagement. The tab is inclined to extend upwardly from its anchoring point, thus limiting downward movement of the slide. A removable pin or hook is inserted into the slot when it is desired to secure the slide in the deployed, locked condition.

Abstract: A multifunctional mobility device for physically disabled people comprises a L-shaped frame having at its lower end a platform adapted to receive thereon a user in a substantially standing position. Front and rear wheels support the frame and the platform. The front wheels are rotatably mounted to the frame just in front of the platform. The frame includes at its upper end a pair of grips which can be grasped by the user when standing on the platform. Therefore, to operate the mobility device, the user must exert on the frame a sufficient force oriented substantially in a forward direction thereby producing a pivot of the frame and of the platform about the front wheel and a rotation of the front wheel which results in a forward displacement of the mobility device and of the user. A stabilizer terminated by a swivel caster is provided in front of the front wheels for limiting the forward pivot of the mobility device. A retractable seat also transforms the mobility aid into a wheelchair.

A pair of primary wheels are attached to the lower end of the secondary frame for rolling the hand truck over a support surface such as the ground or floor. A pair of auxiliary wheels are provided on a swing away frame. The auxiliary wheels can be moved to a position in which the hand truck rests in a stable position on all four wheels. The main frame can then be pivoted about the pivotal connection to the secondary frame to be positioned in a horizontal or near horizontal position elevated from the ground or floor. Heavy objects such as kegs of beer can be rolled directly from a truck, rack or conveyor to the hand truck without requiring the operator to lift the heavy objects.

Abstract: A collapsible table height cart is disclosed for elevating a table top mounted case enclosed machine, such as a voting station for deployment of a direct recording electronic voting machine.

The collapsed cart is flush to one side of the case. The case and collapsed cart transport on a supporting tracking wheel pair protruding from a lower edge of the case at the collapsed cart. Stowing occurs with the case containing the polling station standing on end in a substantially vertical position. Support of the polling station in the vertical stowed position occurs from both the tracking wheel pair and paired arcuate members extending over the bottom edge of the cart.
