Abstract: A latching structure defined by a mount, a handle pivotally mounted to the mount and linked with a latch pin slidably mounted in the mount. The linkage between the handle and the latch pin includes first parallel links pivotally mounted to the handle and pivotally mounted to the latch pin. Second links are pivotally mounted to the first links and to a spring block slidably mounted on the latch pin. A spring is placed in compression between a shoulder on the latch pin and the spring blocks. Consequently, the linkage mechanism operates to actuate the latch pin with the handle and create an overcenter mechanism to bias the entire mechanism to either a fully opened position or a fully closed position. A gasket is provided on a flange associated with the handle to seal the latch mechanism when the mechanism is strongly biased by the spring into the closed position.

Abstract: A padlock-type security seal including a U-shaped shackle having a pair of reversely bend end portions. A body portion and a brightly colored insert are assembled to form a pair of chambers for receiving and locking the bent end portions. Movable tangs and matching cavities are formed as an integral part of the insert adjacent the chambers. The body portion has a plurality of transparent windows adjacent the cavities. Attempts to open the seal by deforming the shackle to remove the bent end portions from the chambers will result in moving the tangs into locking containment with the cavities thereby visually indicating tampering via the transparent windows.

A third frame section telescopes out from the second frame section to provide additional length for the cot. The third frame section is covered by a third sheet which unfolds from the second sheet and is held tautly by connectors underneath. The frame sections are made of tubular aluminum and have rigid downwardly extending u-shaped cross portions which provide legs for the elevated cot. Removable elongated storage pouches fit between the hinged frame sections in the closed position. A detachable carrying harness extends from a closure strap with a buckle which extends around the pack to hold it in the closed position.

Abstract: A multi-purpose patient support and transport apparatus is provided which includes a Trendelenburg mechanism and a novel guard rail assembly. The Trendelenburg mechanism is actuated by turning a handle in one direction. This allows a pneumatic spring connected between the seat and backrest assemblies to be fully contracted, thereby moving the backrest assembly to a Trendelenburg position. When the handle is turned in the opposite direction, the backrest may also be rotated downwardly, but is precluded from moving beyond the reclining position by a stop member which prevents the pneumatic spring shaft from moving entirely within the spring casing. The guard rail is mounted to the frame of the apparatus by a pair of pivot arms extending at an oblique angle with respect to the plane of the rail. This allows the rail to be stored under the frame when in the lowered position.

Abstract: A pillow book construction is disclosed formed of an inscribable, foldable cushion having a pair of spaced padded portions connected by a central unpadded portion. One or more inscribable unpadded sheet-like members are connected to the central portion of the cushion between the padded portions, and are disposed for pivotal movement between said padded portions. The cushion is foldable between an open configuration in which the padded portions are juxtaposed in side-by-side relation and a closed configuration in which the padded portions are disposed in overlying relation with the sheet-like members sandwiched therebetween. The construction is such that when the cushion is in its open configuration, the padded portions form the cover leaves of a book and the unpadded sheet-like members form the pages of a book. When the cushion is in its closed configuration, the book may be used as a cushioned pillow. A strap fastening arrangement serves to releasably retain the cushion in its closed configuration.
