10 results about "Vertical motion" patented technology

A suspended-load backpack designed to permit the load to move relative to the backpack frame during walking and running so that the large movements between the load and the frame of the backpack reduce the fluctuations of absolute vertical motion of the load. Because the hip (and thus the pack frame) go up a down a good deal during walking, a large relative movement between the frame and the load reduces the absolute excursion of the load. This movement may be, in turn, transferred to a motor through, for example, a rack and pinion gear, to convert the mechanical movement to electrical energy. The movement may also be converted to electrical energy by using an electroactive polymer (EAP) to connect the suspended load to the frame. Such designs allow the load to move in a controlled fashion to prevent the patient from losing his or her balance as the load moves up and down along the backpack frame. Such movement of the suspended-load relative to the frame also reduces the forces on the wearer's shoulders while walking or running, thus reducing the likelihood of orthopedic injury.

A method and apparatus for securing non-load bearing interior walls in a wood frame structure in a manner that allows for vertical deflection of the frame includes a plurality of sleeved fastener assemblies, each having a threaded fastener extending through a shorter outer sleeve with an enlarged diameter head. The fasteners hold interior non-load bearing walls in place through a predrilled hole in the top plates of the walls, while being capable of accommodating limited vertical movement caused by vertical deflection of the building frame during construction and beyond.

A chassis stacker having a first and a second vertical storage rack displaced from one another by a distance wide enough to accommodate a trailer chassis, and connected at a top end by a trolley rail support beam. A trolley is positioned on the trolley rail support beam, said trolley having an elevation system capable of raising and lowering a first and a second stabilizing beam that are suspended from the trolley and guided in their vertical motion by low-friction, storage-rack contact members attached at respective first and second ends of the elevating structure, said contact members in contact with an inner surface of the respective first and second vertical storage racks. A first and a second stabilizing-beam trolley is attached to the, respective, first and second stabilizing beams while a spreader containing a chassis-clamping mechanism extends between and attaches to the first and the second stabilizing beam trolley.
