Abstract: A surgical case cart having a closed container supported on a chassis. The closed container includes a pair of front door panels hinged to side door panels which in turn are hinged to side wall sections, so that the container can be completely opened with the front and portions of the sides being exposed by the door panels wrapping around the side and back. The door panels are formed of single pan construction so as to avoid cracks and crevices, and yet exhibit rigidity of a double pan door construction. The lower edges of the door panels provide a baffle effect to reduce the movement of contaminated air into the cart. The top of the cart contains an overhang lip to prevent liquids from spilling into the container. Stem mounted casters are utilized to avoid flat horizontal surfaces on which dirt can collect. The intersection between the back, sides and chassis is constructed to avoid the possibility of collecting contamination and bacteria.

Abstract: A single piece, molded plastic shelf is configured with spaced channels and ribs having slots to provide upward and downward fluid communication with items stored thereon. A generally flat tray of molded plastic is provided with a flange extending upwardly around its periphery. Rib sections are spaced periodically about the tray, forming generally parallel channels to the rib sections to allow free circulation of air and free drainage of liquids from the underside of stored items. Each rib section extends upwardly a greater extent than the peripheral flange. Slots are provided in each rib section further to allow the free circulation of air or other gases while restricting drainage of liquids.

Abstract: A system for securing a member, such as a shelf, to a vertical support column and holding the member in a desired position on the column includes a rotary sleeve system whose resistance to downward motion is directly proportional to the downward force applied. A conical frustum shaped collar having an integral pin extending inwardly from its inside surface rests on top of a split conical frustum shaped sleeve having configurations in the split to receive the pin in one of two positions, an unlocked position and a locked position. A horizontal portion of the slit may be provided for restricting downward motion of the collar with respect to the sleeve to maintain the split in an open configuration, allowing free movement of the rotary sleeve system up or down the vertical column.

Abstract: A modular utility cart includes four corner posts, at least one intermediate shelf and a top shelf. The cart incorporates improved structures for securing the intermediate and top shelves to the posts. Specifically, each intermediate shelf is formed with four open collars each for embracing one post. Each collar has a cross-section substantially congruent to the cross-section of the associated post, and has an upper right tubular portion embracing the post, a lower tubular portion having a downwardly outwardly inclined inner surface, and a transition portion between the upper and lower portions. The top shelf, which is mountable in the region of the tops of the posts, is formed with four blind tubular collars, each having a downwardly outwardly inclined inner surface and an inwardly projecting retaining flange at the bottom edge of the surface.

Abstract: A device stores a plurality of dishes or the like in a plurality of stacks with each stack at an object region within the device. The device includes a generally square base and corner-defining structures that project generally perpendicularly from the base to define the corners of each of four quadrant regions. Divider panels are removably mountable on the base to separate the quadrant regions. Further, partitions are mounted in each of the quadrant regions for selectable movement among first, second, and third fixed positions. All of the partitions, when in the first fixed positions and with the divider panels mounted, cooperate with the corner-defining structures and the divider panels to define four generally equally sized primary object regions. The partitions, when in the second fixed positions with the divider panels demounted, cooperate with the corner-defining structures to define eight generally equally sized secondary object regions.

Abstract: A latch assembly, for holding an object such as a door in either of two positions, includes a catch mounted in fixed position at each of the positions. A latch is mounted on the object and includes two latch portions, each of which is formed to engage and be trapped by one of the catches upon movement of the object toward one of the positions. A first of the latch portions is manipulable from one side of the object to release the other of the latch portions from its associated catch. Similarly, the other latch portion is manipulable from the other side of the object to release the first portion from its associated catch.

Abstract: A system for storing cylindrical articles such as wine bottles, in bulk, comprises a plurality of platforms mounted in spaced, generally mutually parallel horizontal relation and a plurality of spacer walls extending at an oblique angle to and in mutually parallel relation between each two adjacent platforms. Each pair of spacer walls is separated by a distance at least equal to twice the effective diameter of one of the cylindrical articles. Therefore, a first row of at least two of the articles can be supported on each platform between adjacent spacer walls. Additional rows of a number of articles, equal to the number in the first row, can then be supported on an underlying row with a portion of the articles in the additional row supported by and between two underlying articles.
