摘要： An extender accessory for a hand truck having a frame with two vertical frame portions, a plurality of cross bars connected between the frame portions, a pair of axle mounted wheels at lower ends of the frame portions and a platform extending forwardly from the lower ends of the frame portions. The extender accessory comprises an L-shaped support member being of a length longer than the width of the platform. A mechanism is for removably attaching the L-shaped support member against the lower ends of the frame portions and sit upon the platform. The L-shaped support member will overhang opposite sides of the platform, to allow the L-shaped support member to carry and stabilize a variety of loads placed thereon.

摘要： An air purge apparatus and method is presented to protect an imaging system from contamination by particulate matter and other substances in the ambient environment. The apparatus is adapted to be placed adjacent to a viewing window, lens or optics of an imaging system and to provide a protective flow of air. The apparatus includes a curved surface to direct air from a first plenum toward an imaging path in front of the apparatus. The apparatus also includes one or more openings nearer the lens to direct air from a second plenum into the imaging path. The air from the first plenum entrains air from the second plenum and ambient air to create a fluid stream away from the viewing window, lens, or optics and may form a fluid barrier to reduce contamination of a volume of air in the imaging path of the imaging sensor.

摘要： A comprehensive means of providing protection to a bed frame by covering various locations about the bed frame with plastic shields. The plastic shields are adapted to enclose the various locations about the bed frame including the ends of side rails, the junction of side rails and cross members, leg assemblies and the side rails themselves. The shields comprise a pair of housings joined together with a living hinge such that the free ends can be affixed together to surround and enclose the various locations where sharp edges are present. The use of the shields provides overall protection to all of the locations where there may be sharp edges that could harm a person striking the location and thus there is a comprehensive approach to full protection of the bed frame.

摘要翻译： 通过用塑料屏蔽覆盖床架周围的各种位置，为床架提供保护的综合手段。 塑料屏蔽件适于包围围绕床架的各种位置，包括侧轨的端部，侧轨和横梁的连接处，腿组件和侧轨本身。 屏蔽件包括一对壳体，其与活动铰链连接在一起，使得自由端可以固定在一起以包围和包围存在尖锐边缘的各个位置。 使用护罩可以对可能有锋利边缘的所有位置提供整体保护，这些位置可能会伤害击中该位置的人，因此有一种全面的方法来完全保护床架。

摘要： A caster and leg assembly for supporting a piece of furniture on a floor. The assembly includes a caster affixed within a recessed area formed in the bottom of a wooden or plastic furniture leg to create a strong support for the furniture as well as create a good appearance. The caster has at least one spherical roller supported within the housing to allow the furniture to be readily movable omnidirectionally. With one spherical roller, the weight of the furniture acts at the center of the spherical roller. In one embodiment, there are three spherical rollers located equidistant from the vertical center line of the assembly to support the furniture weight equally by the spherical rollers. A glide can be readily attached and detached from the bottom of the caster and, when attached, the glide cup covers the spherical rollers and presents a flat, planar bottom surface.

摘要： A cross member that can be used with a bed frame or bed rails to provide support for a box spring and mattress. The cross member is attachable to the side rail of the bed by a snap-in system where the ends of the cross member are comprised of slide ends that interfit into receptacles located along the side rails. A leg is used to support a bed frame member that is self adjusting by a mechanism that can be unlocked by a person to drop the leg downwardly by gravity to contact the floor and is then lockable in that extended length.
