Abstract: A pair of stackable, nestable blocks for elevating the leg of a bed to a plurality of selectable heights employs first and second blocks that each have upper and lower ends, with recesses being provided in at least one of the ends of each block that can be oriented upwardly to receive and support the foot or lower end region of a bed leg. Each block has a different length, which enables each block, used separately, to support the bed leg at a different height. Recesses of differing depths preferably are provided in opposite ends of at least one of the blocks, whereby the block or blocks that have dual-depth recesses can be inverted to provide bed leg support at two different heights. One of the two blocks preferably has a larger size than the other and is provided with recess(es) large enough to receive and support one or both of the end regions of the other of the blocks, whereby the smaller-size block can be stacked and nested atop the larger-size block to provide still more bed leg elevation heights.

Abstract: An electrical receptacle includes a housing that is defined by identical nonconductive housing halves which are held in side-by-side assembled relationship by a metal mounting bracket. The mounting bracket carries a ground wire connection screw that extends through a rear wall of the housing and threads into a threaded rear end region of a metal post which extends centrally through the housing to provide a threaded front end region configured to receive a cover plate mounting screw. Two nonconductive rotors are journaled by the housing for independent rotation between "off" positions and various "on" orientations for selectively supplying electrical energy to sets of female contacts that are carried by the rotors. A leaf spring is carried within the hollow interior of the housing for engaging detent formations of the rotors for releasably retaining the rotors in "off" and "on" orientations.

Abstract: An insert for positioning between the facing sheets of laminated doors to define lock installation openings and to prevent foamed-in-situ filler material from flowing into lock installation openings during foaming of the door cavity. The insert includes a door edge plate which occupies a portion of the edge of the door, and a receptacle which extends inwardly from the edge plate to locations between the facing sheets. The edge plate defines a plurality of openings, each of a size and shape large enough to accommodate a standard-sized lock bolt assembly. The openings are covered by membranes, any one of which can be removed to permit the receptacle to be attached to the edge plate. The receptacle defines an opening of sufficient size to accommodate standard-sized, door-knob-type lock assembly. An adapter may be installed within the opening of the receptacle to accommodate differently sized lock hardware. All of the insert components can be formed inexpensively using plastics injection-molding techniques.

Abstract: A free-standing rack molded from plastics material provides compartments for upright storage of a booklet, a memo pad or slate-type writing device, and an elongate writing instrument. The rack is configured such that it can be formed in toto in a two-part mold of relatively simple configuration having no side-core pulls.

Abstract: A closure cap particularly suited for use with containers such as milk bottles includes multiple sealing areas as well as frangible locking means. The locking means is located near the lower rim of a skirt portion of the closure cap. If the locking means has not been tampered with, an interlocking engagement between the locking means and a complementary portion of the container retains the cap on the container. If the locking means has been tampered with, the cap can be removed from the container. A visual inspection of the closure cap readily indicates whether the locking means is in tampered or untampered condition. In one embodiment, the cap can be repeatedly snapped into place on the container, and in other alternative embodiments, the cap can be repeatedly threaded onto the container. The multiple sealing areas not only seal the contents of the container, but one of the areas also prevents dust, dirt, or other contaminants from having access to the other sealing areas.

Abstract: An improved method of lubrication in a deep drawing process utilizes a plurality of distinct plastic sheets, loosely overlying one another, laid across at least one major surface of a flat blank to be drawn. In preferred practice, a pair of such distinct plastic sheets are laid across each of the opposed major surfaces of a flat blank in preparation for a drawing operation. The plastic sheets are maintained in position while interfitting drawing tools, namely a punch and a die, close together to effect drawing of the blank. The plastic sheets serve as a lubricant during the drawing process. Selected surfaces of the sheets or the material from which the sheets are formed may be provided with an additional conventional lubricating substance to enhance lubricity of the sheets, or conventional lubricant may be utilized between the sheets of each pair.

Abstract: A fastening system utilizes a tapered plug configured to be matingly received in an elongate, buttonhole-like slot. The slot has an enlarged receiving portion into which the tapered plug can be axially inserted, and a narrower retaining portion having a cross-section which tapers in correspondence with the taper of the plug to establish a snug, secure connection. The retaining portion has an undercut end region which matingly engages a maximum of surface area of the tapered plug to establish a connection which will transmit relatively heavy tension, compression and shear loadings as well as bending moments. The plug is preferably molded from plastics material. The slot is preferably formed using a rotating cutter.

Abstract: A system is provided for pivotally mounting opposed ends of a door panel between a pair of frame or shelf members. The system utilizes a pair of panel-engaging members which have U-shaped cross sections and which receive the door panel ends. Each of the panel-engaging members has a pair of spaced leg portions interconnected by a base portion. A pair of elongate cylindrical projections extends from the base portions to define a pivot axis of the door panel. A pair of projection-receiving formations is provided on the frame members for journaling the projections. At least one of the projection-receiving formations takes the form of an adjustably positioned bearing structure. The panel-engaging members are preferably formed as elongate extrusions of plastics material. One of the panel-engaging members is provided with a handle formation for facilitating movement of the door panel.

Abstract: A tight-fitting corner construction is provided for use between adjacent, integrally connected parts of a common panel. A specially configured, three-sided miter groove is formed between the panel parts, and the panel is folded to close the groove and to form a corner between the panel parts. An overhanging lip is provided on one of the panel parts along one side of the groove. When the panel is folded to form a corner, the lip is brought into overlying engagement with inner surface portions of the other panel part to effect a thorough, tight-fitting closure of the groove. The panel preferably comprises a hollow, elongated plastic member which is used to form the sides and back of a drawer frame. Snap-acting locking devices are carried in hollow portions of the panel adjacent the corner locations to lock the panel in its folded configuration. A drawer front carries connectors which project into hollow portions of the drawer sides.

Abstract: A novel extruded contoured decorative paneling strip is provided for quick installation on the front face of a panel core wherein the strip is preformed to engage the backside and one edge of a core and to engage a detent on the front face of the core. The strip is pre-mitred to compensate for flexing distortion of the contoured cross section of the strip when it is flexed to engage a detent. A novel method of pre-mitring assures a professional appearing mitre between matching contoured strips in contact with each other on the face of the core.
