Abstract: An interlock structure of the cable type for stacked plural drawer cabinet structures which limits the opening of drawers to a single drawer and prevents plural drawers being opened at the same time. An elongate base or frame is mounted in the cabinet adjacent to the drawers. The frame supports plural (one for each drawer) eccentric blocker elements and adjacent follower elements and supports at one end a provided slider element having limited movement. A cable is attached at one end to the slider and at the other end to the frame with an intermediate loop which provide two cable courses, one of said courses threaded on the successive blockers and the other course operably threaded over the respective adjacent followers maintaining the respective blockers and followers in operative engagement. The blockers are moved by interference engagement by a selected drawer.

A longitudinally extending rails assembly is provided within the saddle seat and has a nose pin engaging rail notch provided therein. The saddle seat is provided with a rail retainer member in .sliding engagement with the rails assembly. A rail assembly support rest member is affixed to the saddle seat and is threadably connected to the rails retainer member by use of a rail guide screw member so as to operatively slidably engage the rails assembly between the rest member and the rails retainer member. A transversely positioned saddle nose pin is fixedly provided in the saddle seat go as to selectively engage the rail notch when the saddle seat is moved to its rear position.

Abstract: An improved, universally adaptable, medical intermediate connector having a large tubular opening at one end and a through passage running the length thereof, the body of the connector having a rectilinear cross section with plural planar sidewalls, one of the sidewalls having an extension with projecting fastening knobs and at least one of the sidewalls having a window therethrough, a resilient flexible and elongate strap selectively and adjustably attachable to the knobs and selectively extendable therefrom and returnable to the attachment knobs under tension. A cannula is secured to the body on the axis thereof and projects into the large tubular opening for communicating engagement with a septum inserted guidably into the tubular opening at one end and penetrable by the cannula. A luer socket is an axial extension of the body and communicates with the cannula via the passageway on the axis of the intermediate connector.

Abstract: A drawer interlock structure having a channel-like plural station frame supporting at each station a cam on one side of the frame and an operably connected slider movable by the cam on the other side of the frame. A trip pin is attached to each drawer and is located in the opening and closing of each drawer to operably engage the cam. As the cam moves and the slider is displaced a taut strap of flexible material is displaced against a spring force at opening of any one drawer and the spring is limited in its extension by a blocker whereby no other drawers can be opened until closure of the one opened drawer and whereby simultaneous movement of plural drawers are blocked by the limitedly blocked spring loaded strap. The withdrawal of the slider from a positive block against the cam is prevented until the single opened drawer is closed. Simple locking of the structure is by means of a lock device disabling any movement of the strap.

Abstract: An extendable nesting ski support structure as for supporting cargo including collapsed shelter devices for towing or pulling over ice, snow, and terrain. The skis are pivoted on brackets attached to the supported base and the brackets are atttached to the upper surface of flexible and resilient skis. By longitudinal shifting of the skis they are extendable and retractable as between sill supports beneath the supported base. The resilience and the flexibility improves the support system by providing shock absorption while in the extended position. A single lock serves both the extended and retracted skis, and on extension and locking, the skis are shaped by the flexural characteristics of the material of the ski.
