Abstract: A system for trimming, insulating and sealing between two separate elements of a building structure. The system includes an elongated strip of material, such as wood, having a channel on its reverse side which is wider than the width of a gap in the building structure which is to be covered by the strip. A compressible insulant, such as foam, is disposed in the channel and, like the channel, has a width greater than the width of the gap so that the insulant seals between the two building elements when the strip is installed. The insulant extends outwardly from the channel so that it is compressed when the strip is installed.

Abstract: An elongated safety bar comprises first and second spaced apart flanges and first and second webs which interconnect the associated side edges of the first and second flanges, the second flange, when viewed in cross section, including a flat central portion, and the first flange, when viewed in cross section, including a central portion which is parallel to the flat central portion of said second flange, and opposite generally semicircular end portions, these end portions extending away from the side of an imaginary plane defined by the flat central portion of the first flange opposite the side facing of the second flange. The second flange is longer, viewed in cross section, than the first flange, thus providing the safety bar with a closed, generally trapezoidal-shaped cross section.

Abstract: A butt joint for ends of logs when built into a log cabin. It involves the formation of opposed channels in the butted ends of the log with a drill so that complementary shaped locking members can be driven into the channels and then wedged into tight engagement therewith to join the butted ends.

Abstract: A load-bearing bar (1) for office furniture, the bar having a modular structure and being defined by a number of interconnected modules each consisting in a bar segment (18) having a substantially U-shaped cross-section. Each bar segment (18) is formed by two lateral beams (2) rigidly connected to each other by an intermediate base element (3) which supports a channel-defining member (59) for telephonic and electric wiring.

Abstract: An arrangement for use when casting concrete floors, particularly in locales having pillars, floor drains or the like. The arrangement includes straight concrete beams and sections of ring-like concrete beams which are intended to be incorporated in the resultant floor. The ring sections are arranged to coact in order to completely encircle a free-standing pillar or the like, or to partially encircle a pillar located adjacent a wall. The sections are provided with a lower support flange intended to support the ends of the straight beams. The height of the straight beams is so selected in relation to the height of the ring-like beams that when the straight beams rest on the aforementioned support flange, the upper surfaces of both kinds of beams are located in a common plane, on a level with the resultant floor surface, in order to be able to serve as support paths for concrete smoothing devices. The application also relates to a method for manufacturing beams intended for use with the arrangement.

Abstract: A swimming pool cover for an indoor pool which is designed to cover an in-ground pool that is positioned below floor level in a manner so that it provides a support floor when in place that is merely a continuation of the existing floor and which can be raised up vertically when the pool is to be used and become a false ceiling. The cover is provided with vertical guides that prevent it from twisting or coming out of proper orientation, and the guides have safety ratchets that prevent the pool cover from accidentally lowering. The hoist mechanism is stored out of sight in a crawl space or attic above the normal ceiling and operates through cables and pulleys for positively moving the pool cover between its raised and lowered position so that the pool, when covered, provides floor space for a recreation room or party room and also tends to seal the water surface to prevent excessive moisture from escaping into the room.

Abstract: A flashing member having a two leg construction, such member being adapted for use between the ends of corrugated roof panels adjacent to the open space below ridge type ventilators and the base of the ventilator in its resting position at the ridge of a building roof. The flashing member has a generally V-shape transverse profile, and includes one leg having corrugations formed thereupon to correspond with the surface of the corrugations of the roof panel, and a second leg interval with the corrugated leg, such leg being angularly disposed with respect to the corrugated leg and formed with a substantially smooth, flat and uncorrugated surface adapted to provide bearing support for the ventilator in its resting position. A watertight seal is then disposed between the ventilator and the roof panels.

Abstract: A roof edge assembly includes a resilient member secured to the roof structure of a building. The resilient member has at least one sloping portion protruding upwardly and inwardly and serves to mount and support a fascia member on the edge of the roof structure. The assembly also functions to anchor the periphery of a sheet-like roofing material as well as acting as a gravel stop or barrier preventing water and other substances from falling off the edge of the roof.

Abstract: Method and apparatus for raising and lowering a telescoping mast. A telescoping mast having an upper section slidably received within a lower section is pivotally connected to a base in a horizontal position. A line is connected to the lower end of the upper section and is placed over a pulley mounted on the upper end of the lower section and secured to the base. Upward pivoting of the lower section moves the mast to a vertical position while the upper section is extended by action of the line. Lowering the mast from the vertical position causes contraction of the upper section into the lower section.

Abstract: Angular caps for aesthetically dressing and for stabilizing the upper portion of conventionally intersecting office partitions include an angular roof-plate and several integrally attached depending vertical-plates.Gaps between the roof-plate and the vertical-plates are reinforced with dual-trapezoidal gusset-plates to insure that the angular cap securely and aesthetically embraces the upper portions of intersecting office partitions.

Abstract: A curved corner bent from a hollow-profile construction to form a spacer frame of an insulating glazing, where an opening is provided in the inner wall and in the side walls of the hollow-profile construction in the corner zone, so that a free transverse edge on one side of the opening clamps over a free end portion on an opposite side of the opening when the hollow-profile construction is bent at a right angle to form the curved corner, and a process for the production of the corner, in which the opening is a rectangular cut-out into the inner wall and U-shaped cut-outs cut into the side walls, where the side walls are braced during the bending in such a way that the free transverse edge is guided onto the free end portion to provide flat side surfaces on the curved corner after the bending thereof.

Abstract: An underfloor cable tray assembly is combined with a raised floor and is intermediate the raised floor and a subfloor which supports both in an electrical equipment room. Uniformly spaced stanchions support raised floor joists and floor panels to establish the raised floor for the equipment. Instead of having the communication cables strung without order on the subfloor, the underfloor cable tray assembly is provided to route such communication cables in an orderly manner among the various pieces of equipment. The cable tray assembly is formed from modular cable tray sections having a U-shape in cross section and selected from straight sections, horizontal bends, horizontal tees, and crosses. Splice plates and threaded fasteners interconnect these selected cable tray sections to form the complete cable tray assembly.

Abstract: A joint interlocking system includes T-shaped splines (30) each having arms (32), lips (34) and a center flange (36). The splines (30) are secured within slots (20) formed in the edges of panels (12) or similar articles/members to be interlocked together in various structural configurations. H-shaped connectors (40) each include a cross bracket (42), legs (44) and inwardly directed retaining lips (46). Beads (35) are formed on the ends of the spline lips (34), and project inward toward the associated spline center flange (36). Corresponding beads (48) are formed on the ends of the connector retaining lips (46) and project inwardly toward the associated cross bracket (42). The spline beads (35) can be captured in connector pockets (50) formed by the cross bracket (42), retaining lips (46) and connector beads (48) so as to interlock the splines (30) to the connectors (40).

Abstract: Several horizontal links have inward-projecting horizontal flanges for supporting the treads of a stairway. Such links are uniformly spaced apart elevationally by upright parallel links pivoted to the horizontal links to form a lazy tongs linkage. One such lazy tongs linkage is permanently attached in inclined attitude to the conventional weight-bearing supports for the stair treads, such as sidewalls or inclined stringers, at each side of the rough opening for the stairway. Prior to permanent installation, the lazy tongs linkage can be extended or contracted by conjoint swinging of the upright links to adjust the spacing of the horizontal tread support flanges so that the total rise of the linkage matches the total rise between adjacent floors as actually constructed. The support is designed to fit a range of expected total rises between the adjacent floors while maintaining a rise and run for each step within acceptable limits.

Abstract: Pre-fabricated modular panels for attachment to the exterior walls of existing buildings to provide supplementary insulation. The panels include exterior facing, vertical support ribs, spacer members, a fastening strip secured to the spacer members and compressible insulation mounted from the vertical ribs to provide a ventilation space between the insulation and the facing. When the fastening strip is fastened to the building exterior wall, the insulation contacts said wall and is compressed thereagainst in contour accommodating relationship.

Abstract: An isolator for use in protecting buildings and other structures from the effects of vibration and shock due to an earthquake. The isolator comprises a stack of elastic bearings interconnected at their outer peripheries and located between and coupled to an upper plate and a lower plate. The junctions between adjacent elastic bearings and between the upper and lower elastic bearings and the upper and lower plates are provided with intermediate plates extending beyond the outer peripheries of the elastic bearings. The intermediate plates have aligned holes near their outer peripheries for receiving vertical rods whose lower ends are releasably coupled to rod-holding devices mounted on the lower plate. The rods provide lateral stiffness for the isolator and, by proper selection of the lengths of the rods, the stiffness of the isolator can be adjusted as desired.

Abstract: A system for attaching furring adjacent a column includes a corner clip (140, 142) having a first leg (160) for attachment adjacent a column and a second leg (162) extending from the first leg. The second leg (162) extends substantially longitudinally of the column. The clip may be attached directly to the column or to the ceiling or decking adjacent the column. One end of a corner angle (150) is engaged over the second leg of the clip. The opposite end of the corner angle is engaged over the corresponding leg of a similar clip. The corner angle is then plumbed by moving the second end of the angle and clip, and the clip is attached to the decking or ceiling to maintain the angle plumb. Furring (G) is attached to the corner angle to cover the column.
