Abstract: A tambour or roll-top door and housing assembly comprises a tambour door formed of a plurality of longitudinal segments engaged along their adjacent sides by parallel hinge elements, and a housing having a pair of spaced tracks defining a curved path, the door being positioned with its side edges engaging the two tracks respectively and the segments being relatively pivotable when the door slides around the curve between open and closed positions. The assembly further includes a gear having a circular pitch distance between teeth corresponding to the pitch between the door's hinged segments, the gear being rotatable on a shaft with at least one tooth always engaging one door segment, and a Negator.sub.tm spring having one end secured to the bottom of the door and the remaining spiral portion freely rotatable on the gear shaft.

Abstract: A chair or similar article of furniture is presented having front and rear non-load bearing contoured shells of relatively thin plastic molded material secured together to form the seat portion and back portion of a chair or the like. A rigid pre-formed matrix of sturdy, rigid load bearing construction is disposed intermediate the shells. Means are provided for the attachment of arms to the chair.

Abstract: A seating arrangement comprising a pair of parallel laterally spaced solid block support members interconnected by two suspension rods, one extending between the front central portions of the support members and the other between the top rearward portions of the support members, a composite seat portion and backrest portion extending at an angle to each other, the seat portion being secured to the suspension rod extending between the front central portions of the support members and the backrest portion being secured to the suspension rod extending between the top rearward portions of the support members to provide a free floating chair with distributed balance.

Abstract: The invention is a new hospital bed having a lower frame or dolly, an upper frame or mattress support, and a middle frame comprising two longitudinal beams, a head end, a foot end and a central section. The head end is formed by a single "U" shaped tube which joins the beams, holds a head board, supports the side rails, and provides recesses for IV tube support rods; the foot end is formed by a single channel having similar and additional functions as the head end; and the central section of the middle frame includes a pair of wing-like plates which form a part of and provide the principal support for the upper frame. The total number of components of the bed is substantially reduced by the design of these components to serve multiple functions, which conserves material, reduces expense, and allows for easier repair and adjustment.

Abstract: Raisable safety side apparatus for one or both sides of a hospital bed comprising in each instance a corresponding side frame pivotally connected to lever means, e.g. a pair of spaced apart or parallel levers, adapted to be mounted operatively on a bed to move the side frame from a lower or inoperative position to an upper or operative position with respect to the bed, and resilient biasing means operatively interposed between the frame and the lever means to urge normally the frame to the upper position, e.g.

Abstract: System for controlling selective relative positional movement of portions of a bed structure with respect to a main supporting bed base frame, such as in a hospital bed, in which a single common motor controllable, e.g. by suitably actuatable switch means, for driving operation selectively in alternative forward and reverse directions is utilized, and which contemplates a plurality of independently operable individual motion transmission means connectable to such bed structure portions for correspondingly effecting the selective relative positional movement thereof with respect to the main supporting bed base frame, e.g.

Abstract: A recessed pull for drawers or the like which have inner and outer front panels disposed at the forward end thereof including an aperture in the outer front panel and a trim piece covering said aperture, said trim piece being provided with grooves or slots along the upper and lower edges in which the edges of the aperture are accommodated and a cover member having rear, top, bottom and side walls, is secured to the front surface of the inner front panel by welding directly to the rear of the aperture formed in the outer front panel to provide the recessed pull.

Abstract: A recessed pull is provided for movable panels such as the front panel of a file cabinet, desk drawer or the like in which the front panel has an aperture intermediate its sides, a trim piece having a groove along its upper and lower edges can be snap-fit into the aperture with the edges of the panel around the aperture engageable in the grooves in the trim piece, and the trim piece has beveled portions along the sides of the upper or bottom edge at the rear of the trim piece so that it will slowly deform under pressure when inserted into the aperture and return to normal shape and size upon engagement of the edges of the aperture in the grooves of the trim piece. A cover element having rear, top, bottom and side walls is provided with a downwardly extending flange from the top wall which engages in the groove along the upper edge of the trim piece in back of the edge of the aperture also accommodated within said groove.

Abstract: An electric hospital bed system including a conducting frame and movable parts, an electric device for controlling the movements of the movable parts and a ground circuit monitor operatively connected between a power supply source and the electric device. The monitor continuously senses the integrity of the ground connection between the hospital bed system and the building ground bus-bar, including the ground line in the wall outlet. In the event the ground connection is broken or disconnected for any reason, the power supply to the electric device will be interrupted and switched to a warning device mounted in the hospital bed system or at a remote central monitoring station. The hospital bed system remains inoperative until the ground fault is located and the ground connection restored.

Abstract: A support rod is maintained in position by two load-bearing leaf springs disposed at each end of the rod. The leaf spring members are partially U-shaped in cross-section and the rod is maintained with a loop formed by the U and a back plate. This loop is under a predetermined tautness, the strength of which is created by presetting the tension of a coil spring on the upper flat portion of the load-bearing leaf spring member from which the U-shaped section extends. When an overload is placed upon the support rod, the weight causes the rod to move the U-shaped section of the leaf spring outwardly which thereupon releases the rod from its engagement within the U-shaped loop. As a consequence, the rod will fall with the weight thereon under the force of gravity.

Abstract: Control drawer slide for holding a drawer against unintentional removal in which the track for guiding the drawer during inward and outward movement is provided in the vicinity of its outward end with an interrupting depressed control track section having a downwardly inclined track portion in the direction of inward drawer movement, which cooperates with an offset drawer stop operatively positioned out of the path of the track and extending into the drawer path and situated at a level above the depressed track section to permit intentional downward tilting of the rear end of the drawer at the depressed track section to clear the stop yet hold the drawer upon normal outward movement against unintentional removal by otherwise abutment with the stop.

Abstract: A bumper of a generally U-shaped tubular member whose free ends are pivotally attached to brackets which in turn are secured to the cross rod extending between the front legs of a bed or the like. A balancing spring contact engaging the bracket and the U-shaped bumper member maintains the bumper in lowered position extending from the head of the bed or in raised position wherein it does not substantially increase the length of the bed.
