Abstract: A door is constructed with a separate member joined to the door edge by a tongue-and-groove coupling and screws so as to be readily removable and replaceable. The separate member sustains the impacts imparted to the door by carts or wagons pushed past the door and can be readily replaced when damaged, thus avoiding replacement of the entire door. A flexible cover snaps over the outer surface of the separate member to add impact resistance and aesthetic appeal. Intumescent strips may be inserted inside or outside of the cover to enhance sealing between the door, and as adjacent door or door frame, thereby improving the fire resistance rating of the door. Accent strips or reveals of contrasting or complementary colors may be incorporated to add to the aesthetic appeal of the door. The door construction is of particular utility in schools, health care facilities and other institutions.

Abstract: A rail and wall support installation includes an adapter which mechanically couples a wall support having a rotatable locking cam portion to an undercut groove on the rear of the rail. The adapter serves both as a mechanical attachment point for the rail to a wall support and to transfer the camming action of the locking cam portion to the rail. The adapter allows existing wall supports to be used with rails that are not directly compatible with the locking member, such as pre-existing rails.

Abstract: A seismic roof motion-absorbing gap cover assembly includes an elongated y-axis slideway affixed to a building unit B on one side of the gap and extending parallel to the gap and a y-axis slider slidably received on the y-axis slideway. Roof support members are secured to the y-axis slider in spaced apart relation against horizontal movements. A roof having one end affixed to a building unit A on the other side of the gap spans the gap and is supported on the roof support members by elongated spaced-apart x-axis slide members for movement along an x-axis perpendicular to the gap. Each x-axis slide member has a length such that it is supported by the roof support member throughout a range of displacements in the x-axis direction of the building units between maximum and minimum design displacements in an earthquake from a neutral position.

Abstract: A wall protector includes a retainer that is adapted to be attached to a building wall and a cover of an impact resistant thermoplastic polymeric material in the form of a thin web of suitable cross-section attached to the retainer portion of the retainer. The cover includes at least one substantially straight portion of substantially uniform cross section along its length and having a face portion overlying the retainer and an integral transition portion that is integral with the straight portion has an end wall that curves smoothly away from the face portion of the straight portion from a rounded juncture with the face portion and overlies and conceals the end of the retainer. The integral transition portion may be configured as an end cap or a wall return piece that forms a transition between the straight portion and a wall surface or as a corner piece that joins sections of wall protectors mounted on walls that intersect at a corner.

Abstract: A wall protection assembly includes an elongated wall protector member having an impact surface adapted to face away from a wall and a mounting surface adapted to face the wall. At least two resilient mounting clips secure the protector member to the wall. Each mounting clip has a mounting base adapted to be affixed to the wall in concealed relation to the protector member and at least one resilient hook projecting from the base and received in a groove in the protector member in captured relation.

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 undercut 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: An expansion joint cover for bridging an expansion gap between first and second building floor members has a pivot frame adapted to be affixed to the first building floor member, the pivot frame including a base portion and a longitudinally continuous bearing of spherical cross-section supported by and located above the base portion, and a slide frame adapted to be affixed to the second building floor member. A cover unit is pivotally mounted in spaced-apart relation to a proximal end thereof on the bearing in cantilevered relation to the bearing, is adapted to span the gap, and has a distal end supported on the slide frame. A plurality of spaced-apart compression spring units engaged between the base portion of the pivot frame and a portion of the cover unit intermediate the proximal end and the bearing bias the cover unit about the bearing so as to forcibly engage the distal end of the cover unit with the slide frame.

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 foot mat has a plurality of elongated rail members (20) arranged closely adjacent each other with a gap between each adjacent pair of rail members. Each rail member is of uniform cross section along its length and includes a body portion (22) and a pair of spaced-apart dependent leg portions (27). An elongated tread member (100, 104, 106, 108 or 110) is received on the upper surface of each rail member. Each adjacent pair of rail members is joined by an extruded plastic connector member (30) that has a connecting web portion (32) and a pair of generally U-shaped socket portions (38). Each leg portion of each rail and each socket portion of each connecting member are configured to snap-fit together and have interengaging shoulders (27s and 38s) that are configured to retain the leg portion in the socket portion.
