Abstract: A demountable modular wall system including a series of individual wall panels that can be positioned adjacent to each other. The demountable wall system includes a doorway defined by a pair of spaced vertical posts and a horizontal header. In one embodiment, a sliding glass door is movable along a sliding door track mounted to the horizontal header. A lower trim assembly mounted to the bottom end of the sliding glass door adjusts the overall height of the door. The doorway can also include a pivoting glass door. The pivoting glass door includes a bottom pivot assembly having a bottom clamp adjustably positioned along a bottom end of the pivoting glass door. The adjustable bottom clamp can be moved along the bottom end of the pivoting glass door and receives a pivot pin supported on the floor. A top pivot assembly includes a movable plunger that defines a portion of the pivot axis for the pivoting glass door.

Abstract: A wall panel-ceiling engagement device is designed to couple a wall panel to a ceiling. The engagement device, when engaged with the ceiling, holds the wall panel stationary without any fasteners, braces or other securing members that penetrate into the ceiling. The engagement device includes a pair of wall extensions secured to opposite sides of the wall panel and that contain a sound and/or attenuating material, such as a foam material, therebetween. Corner braces are used to join adjacent wall-panels to one another. The corner braces also function to allow the wall panels to sway as a collective and connected unit during seismic events.

Abstract: A sliding door is secured to one side of a wall or partition panel having a door opening, and includes a trolley that is held in a track located above the door opening. The wheels or rollers of the trolley move along the track when the door is moved to a closed position until the roller contacts a wedge or ramp associated with the track. The wedge urges the roller inwardly toward the wall or partition panel, such that when the door is in the fully closed position, the trolley is positioned inwardly on the track to move the upper area of the door into engagement with the wall or partition panel. The lower end of the door includes a channel within which is positioned a follower attached to a swing arm, which simultaneously draws the lower end of the door into engagement with the wall or panel.

Abstract: A connection system for securing a wall panel shell to a frame member. The frame member includes a groove and the shell includes a mounting member received within the groove. The shell includes a skin member secured to one or more structural members. Each mounting member is carried by a structural member, and is part of a connector that is separate from and engaged with the structural member. The connector includes a base having spaced apart engagement areas, which are received within spaced apart recesses in the structural member. The structural member defines a flat surface which facilitates application of pressure to bond the structural member and the skin member together using an adhesive. Thereafter, the connector is engaged with the structural member via a snap-on engagement arrangement, to enable the wall panel shell to be mounted to the frame member.

Abstract: A connection arrangement for securing first and second members together includes a connector member that engages both the first and second members, and a fastener which interacts with the connector member to simultaneously fix the position of the first member relative to the connector member and to provide frictional engagement of the second member with the connector member. The connector member includes a head portion received within a recess in the first member, and a slidable engagement arrangement for providing slidable engagement of the connector member with the second member. The connector member includes a channel within which an expandable engagement wall of the second member is received. The expandable engagement wall defines a passage, and the fastener extends through aligned openings in the first member and the head portion of the connector member, into the passage defined by the expandable engagement wall of the second member.

Abstract: A space dividing system includes a column and a series of partition panels adapted for interconnection with the column. The column includes an internal passage, and is adapted to receive wiring from a building for supplying power to a receptacle arrangement interconnected with the column. Adjacent panels are connected to the column at spaced locations, and the receptacle arrangement is exposed between the adjacent panels. The column includes a structural skeleton to which the receptacle arrangement is mounted, and a series of covers are releasably engaged with the structural skeleton for finishing the aesthetic appearance of the column. An adjustable height mounting arrangement is interconnected with the upper end of the column for connection to a ceiling to stabilize the upper end of the column. Each panel is in the form of a frame defining an opening within which a core is received.

Abstract: A connection system for securing a wall panel shell to a frame member of a frame-type wall system includes a groove in the frame member and a mounting member associated with the wall panel shell, which is adapted to be received within the frame member groove. The wall panel shell is constructed of a skin member which is secured to one or more stiffeners or structural members, and each mounting member is carried by one of the stiffeners or structural members. The mounting member forms a part of a connector member, which is separate from and engaged with the structural member. The connector member includes a base having a pair of spaced apart engagement areas. The structural member includes a pair of spaced apart recesses which are adapted to receive the spaced apart engagement areas of the base. The recesses and the engagement areas are configured with a snap-on engagement arrangement for providing quick, easy and accurate mounting of the connector member to the structural member.

Abstract: A folding table or desk includes a table top, a pair of spaced apart legs, and a wire management structure pivotably mounted between the legs. The wire management structure includes a front panel assembly having an opening, and an access member is pivotably mounted to the front panel assembly for movement between an open position, a closed position and a collapsed position. The front panel assembly can be folded against the underside of the table top and the access member can be pivoted to its collapsed position relative to the front panel assembly, and the legs are foldable over the wire management structure to provide a compact envelope for the folded components of the table assembly. The front panel assembly includes a cross brace member which is engageable with the legs when the wire management structure is in its operative extended position, to impart rigidity to the table assembly.

Abstract: An adjustable armrest assembly for a chair provides adjustment in both the vertical and horizontal position of an armrest member. A tubular member is adapted for telescopic mounting to an upwardly extending support member mounted to the chair. The support member includes a series of spaced teeth defining indentations therebetween. The armrest assembly includes a pivotable latch member which is secured to the tubular member utilizing a cap member mounted to the upper end of a passage defined by the tubular member. The cap member and the tubular member define cooperating mounting structure for providing pivoting movement of the latch member. The latch member is movable between an engaged position, in which the latch member is engaged with an indentation between the teeth defined by the support member, and a disengaged position in which the latch member is moved out of engagement with the teeth.
