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.

Abstract: A spring biased hinge for refrigerator doors and the like includes a stationary mounting bracket, a bent-wire spring mounted between the door and bracket, and a pivot pin for pivotally mounting the door to the mounting bracket. The mounting bracket is reversible so that it can be used on either side of the door, and includes a slot for receiving an end of the spring, the slot and spring being located so that as the door is opened, the door travels through a first arcuate segment where the spring is compressed and oriented to bias the door closed, through a second arcuate segment where the spring is compressed and oriented to bias the door open, and a third arcuate segment where the spring is not compressed but rather slides in the slot allowing the door to swing freely open until an end of the slot is engaged to limit the maximum door open movement. The hinge is characterized by its low profile and low number of parts.

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: A double-pivot door hinge is disclosed that is particularly suited for household appliances such as refrigerators or microwave ovens. The hinge arrangement allows the appliance door to be opened a full 180 degrees from its closed position without coming into contact with a flush mounted wall such as an abutting kitchen cabinet. The hinge has a first pivot pin and a stop arrangement which allows a door to be swung outwardly until a 90-degree position is reached whereby the stop arrangement is engaged. Upon further outward movement, the assembly shifts to a second hinge pin until a 180-degree position is reached. The movement from the 90-degree position to a 180-degree position requires the overcoming of a spring force of the hinge arrangement.

Abstract: A drawer interlock combination for a stack or tier of drawers and simplified to include a frame forming a receptacle guide for a plurality of rotors, one rotor for each drawer in the stack and the same frame guiding a plurality of actuators, one for each drawer through a path limited in both extremes of travel and displaceable by the action of only one of the rotors so that only a single drawer may be opened at a time and plural drawers cannot be opened concurrently. The device may be completely locked by simple blocking of the travel of the actuators to less displacement than by an single of the rotors. The structure is simple, economical and easy to install. The parts repeat themselves and provide excellent drawer stabilization with overall locking of all drawers.

Abstract: The specification discloses a partition system in which any gap between an end partition and an existing wall is concealed by a combination rigid channel and flexible cover. The rigid channel embraces and provides firm anchorage for the end of the partition and a flexible cover on each side of said channel conceals the rigid channel and any gap between the partition and a fixed wall from view. Yet, the flexible cover can be deflected to provide access to hanger bracket slots or the like which might be located at the end of the partition.

Abstract: Modular wall panels and ancillary furnishings and fixtures, such as shelves and cabinets, having a single load-bearing connector post between two coplanar panel members. The panel members engage apertures in the side walls of the connector post. The front and back walls of the connector post are vertically slotted with a width dimension to support hooks from two brackets within each slot, one from the left and one from the right sides of adjacent shelves, desk surfaces or cabinets. Thus, the connector posts directly support all of the system load without lateral force transfer from intermediate load bearing members. The load is transmitted vertically downward to a support surface, usually a floor. At intersections of non coplanar panels, a connector post terminates each planar panel run and is joined to a non load-bearing intersection post at a side wall of each connector post.

Abstract: A floor-to-ceiling wall system having telescoping studs that extend between a ceiling bracket and a floor leveler assembly. The floor leveler assembly includes a leveling channel that is adjusted in order to level an entire wall. During assembly, a first telescoping stud is secured between the ceiling channel and floor leveler assembly and vertically aligned. Thereafter, subsequent studs are automatically aligned by the securing of horizontal stringers sequentially between the telescoping studs. Door jams and window frames are secured to the studs, and wall panels are hung from the horizontal stringers. Adapter brackets hung from the vertical studs accommodate wall accessories with various mounting hook patterns in order to adapt the wall system to a wide variety of wall accessories.

Abstract: The specification discloses a structural connector for pivotally connecting two support members to form a folding truss. The support members can be pivoted with respect to the connector between collapsed and extended positions. The connector includes a generally planar body, a locator tab extending from the body and secured between the support members when in their extended position to orient the connector with respect to the connector, and spring clips extending from the body to lock the support members in their extended position. In an alternative embodiment, the connector includes two of the locator tabs to maintain the support members in spaced relation so that a ridge member can be positioned therebetween.

Abstract: The pop-up electrical receptacle unit, when mounted in relation to an opening in a desk or table, enables the user to effect a retracted or concealed condition of the receptacle by pressing the receptacle downwardly and then permitting the receptacle to rise slightly by means of a coil spring. Such action rotates a ratchet mechanism into an obstructive relation with a pin carried on an actuator attached to the underside of the receptacle and movable therewith. The user effects a protracted or exposed condition of the receptacle by again depressing and releasing the receptacle so as to rotatively index the ratchet mechanism into an angular relation in which the actuated pin is no longer obstructed, the receptacle then being thrust upwardly by the coil spring into its protracted position in which position the prongs of an electrical plug can be inserted into the elevated receptacle.

Abstract: A mail or storage box for suspension between spaced-apart parallel vertical members and secured thereto in cover contact with a horizontal plane surface. The box is suspended by means of a compound pivoting arm arrangement to close against the cover surface and to be capable of opening from the front or rear in such a manner that upon opening the edge of the box falls away from the cover while progressively tilting as the opening proceeds toward a stop position where the contents are revealed and presented to the person opening the box. On closing a reverse progression occurs. Compound pivoting is achieved using a pair of pivot arms at both ends of the box and arm both pivotally secured to the end closure of the box at the top and at the bottom to an attachment plate. The attachment plate is the means for suspending the box in the space between the vertical supports and against the upper closure.
