Abstract: An article of furniture for sitting includes a closed frame covered by a flexible cover. The opposite sides of the frame are captured in retainers formed in counterfacing surfaces of upright support members held in spaced relation by spacer members. The opposite sides of the frame are resiliently flexible so that they can be stressed from a natural spacing to a lesser spacing without exceeding the elastic limits of the frame sides. When the frame sides are retained by the support members and those members are connected to the spacer members, the frame sides, usually constrained by a nonextensible band or by the fabric cover, possess appreciable stored energy tending to urge them apart toward their natural spacing so that the frame sides are retained securely by the support members under the weight of an ordinary person.

A plurality of interchangeable hollow reinforcing box panels also formed from sheet metal are secured to the web portions of the columns by fasteners hidden within the box panels. Each box panel is composed of the central rectangular wall sections, parallel top and bottom walls, parallel side walls with coplanar tabs extending toward one another from the edges of the side panels and positioned in overlapping face-to-face relationship with the webs of the columns. The fasteners extend through the webs into the tabs to hold the panels in place.

Abstract: A horizontal sliding door for a housing such as a cabinet. An axle rotatably mounted at the rear of the door projects into two identical tracks one at each side of the housing. Each track has a lower toothed rack and an upper stop surface facing the rack. A pinion slideably and non-rotatably mounted on each end of the axle engages the rack and is held there by an idler wheel slideably and rotatably mounted beside each pinion. A spacer sleeve near one end of the axle is removable, allowing one pinion and idler wheel to be slid inwardly, allowing removal of the door by passing that one end of the axle through a slot in one end of the track.

Abstract: A cantilever type seating unit with a back that can be secured to a wall surface including a shell in the form of a contoured plate having hook members attached to a rear surface of the back and fastening members attached to an undersurface of a seat portion, and a support frame including a pair of L-shaped support arms and a seat plate unitarily connected to the L-shaped support arms and having fastening seats attached to its upper surface. After the support frame is bolted or otherwise connected to the wall surface, the shell can be firmly fastened to the support frame by first hitching the hook members to upper ends of the L-shaped support members and then bringing the fastening members into fastening engagement with the fastening seats. The seating unit is simple in construction, easy to assemble and light in weight.

Abstract: A combination storage, display and serving utensil with a base having two surfaces, the upper surface being provided with a central raised retaining portion and the under surface having supporting members spaced between the center and the edge of the base and with a bowl-like member having a closed end forming a shoulder, an open end and a sidewall therebetween. A raised knob is provided centrally of the shoulder on the bowl-like member. When the utensil is in its storage and display mode the edges around the open end of the bowl-like member surround the raised retaining portion of the base and when the components are mutually inverted and the utensil is in its serving mode, the shoulder on the closed end of the bowl-like member rests on the supporting members with the open end facing upwardly.

Abstract: A headrest includes a unidirectional clutch permitting adjustment of the headrest from a reference position to any desired selected position and resists motion in a rearward direction except upon release of the clutch. In one embodiment of the invention, a spring return mechanism is provided to automatically return the headrest to a reference position upon release of the clutch.

Abstract: The cover for an open front portion of a housing is slidable rearward to expose the open front portion, and has a pivotal front wall. The front wall has side walls connected to it, forming a front section, and is coupled to the housing and the rest of the cover such that the front section pivots to bring the front wall into a horizontal position during the first part of the rearward sliding movement.

Abstract: A vehicular seat for handicapped and elderly persons is disclosed which is readily accommodated in any type of conventional vehicle, such as automobile, van, bus and the like. The vehicular seat is given three degrees of freedom of movement, the first degree being a rotary one in a horizontal plane about a shiftable vertical axis of rotation, the second being a rectilinear one in a horizontal plane, and the third being rotary in a horizontal plane about a fixed vertical rotary axis. The three degrees of freedom allow for angular positioning of the seat proper relative to the ajar door, so as to ensure minimal interference between the person being seated and the frame and ajar door of the vehicle.

Abstract: A security stand having a horizontal mounting surface, first and second sides of a width lesser than the depth of the horizontal mounting surface, a top surface extending between the two sides and a lipped shelf extending between the first and second sides and between the horizontal mounting surface and the top surface. The shelf with the lipped edge is mounted in a secure fashion such that equipment mounted or resting therein cannot be removed without removing the shelf. The horizontal mounting surface has means for attaching a computer keyboard prior to mounting the horizontal mounting surface onto a table such that the keyboard may not be removed. Additionally, secure mounting means may be provided in the top surface for mounting a Cathode Ray Tube before insertion of the lipped shelf and equipment therein.

Abstract: An adjustable anchor mounting device suitable for use in a vehicle seat belt. The device comprises a base having a plurality of interlocking means provided spacedly along the direction of displacement of an anchor, a slide member guided along the base and carrying the anchor thereon and a latch piece supported on the slide member. In one embodiment, the latch piece is normally inhibited from being disengaged from the interlocking means owing to the provision of lock means which may preferably have a first member coupled at a part thereof with the slide member and a second member coupled at a part thereof with the latch piece. In another embodiment, the latch piece may be kept in engagement with the base by second engagement means and may be disengaged from the base by the first engagement means. The device permits a prompt, smooth and fail-free adjustment of the position of the anchor, e.g., a deflector. The latch piece can be kept in engagement with the base even if the vehicle is overturned.

Abstract: A sliding door arrangement which provides lateral support for the free edge or bottom nose corner of a door comprises a retractable member which is raised through an aperture in the floor or doorway threshold to interlockingly engage said edge of the door in the closed position. When the door is opened the engaging member is automatically retracted to lie flush with the floor surface. The member is carried by a rocking lever under the floor which is linked to another counter-balanced lever nearer the door frame which also has a raised protrusion which is abutted by a cam on the door as it reaches the closed position.

Abstract: A clamping device comprises a holder in which an actuation arm is movable in a longitudinal directions. A fixed clamping jaw is carried by the holder and a movable clamping jaw is arranged within the holder opposite to the fixed clamping jaw and it is supported by at least two longitudinally spaced lever members which have a first pivotal connection to the holder, a second pivotal connection to the movable clamping jaw and a third pivotal connection to the actuator arm. An actuator is connected to the arm to move it backwardly and forwardly for opening and closing the jaws. The pivotal connecting points of the levers are chosen so that the pivotal points are disposed at substantially right angles to each other. The pivot pins are cylindrical hinge pins and the line between the pivotal connection of the lever to the jaw and to the fixed holder makes an angle of 45.degree. to the horizontal so that a larger distance between the points of support is possible.
