Abstract: A seismic expansion joint cover includes a bridge panel having one end supported for movement in the y-axis direction and against movement in the x-axis direction relative to a floor A on one side of a motion-absorbing gap and supported at the other end for movement in the x-axis direction and against movement in the y-axis direction relative to a floor B. A recess in floor B receives a portion of the bridge panel in all positions of the bridge panel relative to floor B. A recess cover plate covers the recess, is supported at one end in sliding relation on the bridge panel in all positions of the bridge panel relative to floor B and is joined at the other end to an end member of the recess frame remote from the gap. A resiliently collapsible/extensible honeycomb panel received in the recess in floor B supports the portion of the recess cover plate that spans the recess between the end of the bridge panel and the end member of the recess frame.

Abstract: A seismic expansion joint cover assembly installed at a motion-absorbing gap between a member A on one side of the gap and a member B on the other side of the gap includes a cover panel spanning the gap and a hinge joining one edge A of the cover panel to the member A for pivotal movement about a pivot axis. The pivot axis is spaced apart from the expansion gap so as to enable a stop between member A and the cover panel to prevent the cover panel from pivoting about the pivot axis into the expansion gap upon widening of the expansion gap. A permanent magnet and magnet striker releasably secure the other edge B of the cover panel to the member B. A tensioned cable connected between the cover panel and one of the members A and B limits the pivoting movements of the cover panel and automatically recloses the cover panel over the gap.

Abstract: An end member is joined against axial displacement to a handrail by a lock member that is coupled to a mounting flange portion of the end member against axial movement and for rotation relative to the mounting flange portion. A locking cam portion of the lock member is received in an under cut mounting groove of the handrail and is configured to permit the lock member to be moved axially along the locking groove in an unlocked rotational position relative to the locking groove and to frictionally engage walls of the locking groove in a locked rotational position relative to the locking groove and thereby retain the end member against axial movement relative to the handrail.

Abstract: A handrail/leaning rail includes a mounting system adapted to be attached to a wall and an elongated rail separate from the mounting system and removably attached to the mounting system. The rail has a handgrip portion having a top surface and undercut front and rear surfaces shaped for grasping by a user, the rear surface being positioned on the rail to be spaced apart from the wall. A safety blocking portion that is longitudinally coextensive with the handgrip portion and extends rearwardly from a lower base portion of the rear surface of the handgrip portion blocks a gap that would otherwise be left between the lower base portion of the handgrip portion and the wall. The rail also has a wall shield flange portion that extends upwardly from the safety blocking portion and is spaced apart from the rear surface of the handgrip portion.

Abstract: An expansion joint cover installation includes first and second building members defining an expansion gap between them and a cover member spanning and covering the gap and engaging the building members. The cover member is held centered in the gap by a resilient centering system that is coupled between the building members and the cover member and includes a plurality of first tensioned flexible segments connected obliquely between the first building member and the cover member and a plurality of second tensioned flexible segments connected obliquely between the second building member and the cover member. By arranging the tensioned segments obliquely to the axis of the gap, they are relatively long and are able to provide an adequate centering force over a relatively large range of motion between open and closed states of the gap.

Abstract: An expansion joint cover for concealing an expansion gap between building members comprises retainers attached to building members on each side of the expansion gap and a cover panel spanning the expansion gap and overlying at least portions of the first and second retainers and a portion of the building member on at least one side of the gap. The cover panel is attached to the retainers by axially releasable fasteners, such as hook and loop fasteners.

Abstract: A seismic expansion joint cover includes a floor bridge panel having mutually perpendicular elongated U-shaped bearing receiver guideways adjacent its opposite ends slidably supported by linear bearings affixed to the floor portions on opposite sides of the gap. The receiver guideways are open vertically to allow the floor bridge cover to displace vertically. A cover plate frame defines the boundaries of a floor recess that receives portions of the floor bridge panel in all relative positions of the floor portions as the width of the gap changes. The portion of the floor bridge panel that overlies the gap is covered by a first floor cover plate, and the recess and the remaining portion of the floor bridge plate are covered by a second floor cover plate, which is supported by the cover plate frame and by the portion of the floor bridge panel that it overlies. The second cover plate is resiliently attached to the cover plate frame so that it can lift up and ride over the first cover plate when the gap narrows.

Abstract: A seismic expansion joint cover for concealing an expansion gap between building members comprises retainers attached to building members on each side of the expansion gap and a cover spanning the expansion gap and overlying at least portions of the first and second retainers and a portion of the building member on at least one side of the gap. The cover is attached to the retainers by releasable fasteners, such as hook and loop fasteners, that enable it to detach completely from the retainers in an earthquake and to be subsequently reattached. One element of each of the fasteners on one side of the gap is attached to a slider that slides along a track affixed to the internal side of the cover to enable normal thermal expansions and contractions of the gap. Tethers keep the cover from falling to the floor and becoming an obstacle to persons moving through the building.

Abstract: A louver has vertical blades arranged in a frame alternately in a staggered relation from front to back in a front and a rear row. The blades in at least the front row have a web oriented substantially perpendicularly to the plane of the frame and substantially parallel to the jambs, a pair of front flanges extending in opposite directions generally laterally from a front edge of the web, and a pair of rear flanges extending in opposite directions generally laterally from a rear edge of the web. The webs subdivide the air flow volume within the frame into flow channels, each of which is partially blocked laterally by the front flanges and the rear flanges of the blades of the front row. The blades of the rear row have flanges that block the portions of the channels between the extremities of the flanges of the blades of the front row.

Abstract: A foot grille comprises a multiplicity of elongated plank members, each being of substantially uniform cross-section along its length and including a substantially planar base portion having parallel side edges and at least two supporting leg portions depending from the base portion, extending longitudinally substantially coextensively with the base portion, and being adapted to support the base portion in spaced relation above a supporting surface. Tread members are attached to the upper surface of each plank member. A snap-fit coupling joins each adjacent pair of plank members along a juncture between their adjacent side edges. Each snap-fit coupling includes first and second arm portions on one of the adjacent plank members that are resiliently deformable relative to each other and a third arm portion on the other of the adjacent plank members that is received between the first and second arm portions of said one plank member.

A bumper-retaining portion of the retainer includes a generally vertically oriented web, to which a handgrip-retaining portion spaced apart above the web is joined by a connecting portion. A bumper member is mounted on the front of the web of the bumper-retaining portion, and a handgrip member is mounted on the handgrip-retaining portion of the retainer. The handgrip-retaining portion has a base joined to the connecting portion, the base being inclined upwardly and rearwardly with respect to the front part of the bumper-retaining portion, and a pair of spaced apart retaining flanges extending generally upwardly from the base and defining a channel.

Abstract: A drainable blade louver comprises a multiplicity of inclined blades extending horizontally between the jambs of a frame. Each blade has in cross-section a base portion sloping smoothly upwardly from a lowermost point at the front edge of the blade to an uppermost point proximate to the rear edge of the blade. The undersurface of the base portion is free of protuberances so that there are no drip points and water clinging to the undersurface of the base portion is transported along the undersurface by the air flowing through the louver. A generally C-shaped bottom trough portion adjacent the upper edge of the blade captures water blown along the undersurface of the blade and drains it to the jambs. A front drainage trough, an intermediate drainage trough, and a rear drainage trough on the top surface of each blade provide high capacity water-capturing ability. Water captured in each drainage trough is flows along each trough to respective front, intermediate and rear drainage channels in the jambs.
