    • A shelf stores items and provides for organized and attractive display with ease of item access. Conforming to a defined physical environment or variable storage space optimally requires the shelf to provide for both vertical and horizontal adjustment. Here this is accomplished by a pair of legs that are telescopic (to reduce size) and can be locked at a height (vertical adjustment) by use of a pawl, pin, screw or other fastener known in the art. The shelf includes a planar surface that is comprised of a shelf portion, which is supported on each distal end by a leg extension. The leg extensions are mounted to the upper area of the legs. The leg extensions are received by the shelf portion, being movably mounted thereto. This allows for horizontal (width) adjustment. An end cover can be used to provide a flat surface that is consistent with the upper surface of the shelf portion. Feet are added to provide a more solid footing, the feet being removable and providing a mounting tab at the end of the legs and a mounting tab receiver at the opposite end of the legs. This allows for multiple shelves to be securely mounted one on the other.
    • 货架存储物品,并提供有条理和有吸引力的显示,便于物品访问。 符合定义的物理环境或可变存储空间最佳地要求搁板提供垂直和水平调整。 在这里,这是通过使用本领域已知的棘爪,销,螺钉或其他紧固件伸缩(以减小尺寸)并且可以被锁定在高度(垂直调整)的一对腿来实现的。 搁板包括平坦的表面,该平坦表面由搁架部分组成,搁板部分由腿部延伸部支撑在每个远端。 腿部延伸部分安装在腿部的上部区域。 腿部延伸部由搁板部分接收,可移动地安装在其上。 这允许水平(宽度)调整。 可以使用端盖来提供与搁板部分的上表面一致的平坦表面。 添加脚以提供更坚实的基脚,脚是可移除的,并且在腿的末端提供安装突片和在腿的相对端处的安装突片接收器。 这允许将多个货架牢固地安装在另一个上。

    • A hospital bed including a base adapted to roll over the floor, a litter disposed on the base upon which the patient rests, a lift assembly designed to selectively position the litter a selected vertical distance above the base and at least one stabilizer unit between the litter and the base. Each stabilizer unit includes a pair of rack-and-pinion assemblies that extend between the base and the litter. The pinions of the rack-and-pinion assembly are connected together to rotate in unison. Owing to the interconnection of the pinions, the rack-and-pinion assemblies are prevented from moving vertically in directions opposite to each other. This lock-out of the rack-and-pinion movement prevents the litter from moving side-to-side. The stabilizer unit thus prevents the undesirable side-to-side rocking movement of the litter.
    • 包括适于在地板上滚动的基部的医院床,设置在患者所在的基座上的垃圾,提升组件,其设计成选择性地将垫料定位在基座上方选定的垂直距离,以及垫料之间的至少一个稳定器单元 和基地。 每个稳定器单元包括在基部和垫料之间延伸的一对齿条和小齿轮组件。 齿条齿轮组件的小齿轮连接在一起以一致旋转。 由于小齿轮的互连,防止齿条和小齿轮组件沿彼此相反的方向垂直移动。 齿条和小齿轮运动的锁定可以防止垃圾移动到侧面。 因此,稳定器单元防止了垃圾的不期望的侧向摇摆运动。

    • A desk frame including a base consisting of a pair of vertically extending transversely spaced members, a sub-frame vertically movably adjustably supported by the base, and including a pair of vertically extending members telescopically received within the vertical members of the base, a drive assembly to move the subframe vertically relative to the base, the drive assembly including a rack gear attached to each vertical member of the sub-frame, a pinion gear meshingly engaged with each rack, with the pinion gears being rotatably supported by the base, a shaft extending between the two pinions to transmit rotary power therebetween, a worm gear meshingly engaged with one of the pinions, and rotatably supported by the base, a drive shaft fixed to the worm gear and extending therefrom to a position manually operable by a user of the desk, and wherein the drive shaft is also adapted to be supported by the sub-frame.
