A frame assembly, for use in window and door applications configured to retain a panel, comprising a frame with a cover assembly and a support assembly having a track assembly, and a sill assembly and a header assembly both interconnected to a securing surface. The cover assembly is interconnected to the support assembly. The sill assembly comprises a roller member disposed in supporting relation to the track assembly, and the header assembly is disposed in supporting relation to the support assembly so that the frame is movable relative to both the header assembly and the sill assembly. At least a portion of the frame comprises a predetermined thickness of about 1 and 3/16 inches and a predetermined width of about 2 and inches. The predetermined thickness is substantially less than the predetermined width so that both cooperatively and concurrently enhance viewing through the panel and the frame's stability.

Provided is a protective cover for a weighing instrument in which movement of a sliding door does not degrade over time. A protective cover (2) for a weighing instrument includes sliding doors (2L, 2R) defining a weighing chamber (5), an upper frame (11) formed at an upper edge of the sliding door, a lower frame (12) formed at a lower edge of the sliding door, an upper guide rail (17) disposed on the upper frame, and a lower guide rail (18) disposed under the lower frame, where the upper guide rail suspends the upper frame, and between the upper guide rail and the upper frame, balls (215) are disposed at a plurality of positions in a moving direction of the sliding door.

A panel door system has at least two support tracks and at least two panels hanging from the at least two support tracks. The at least two support tracks are mounted to a support structure such that each support track is offset from a previous support track both horizontally and vertically. The least two panels are hung using hanging mechanism such that each panel is hung on a different support track. The at least two panels create a door. The at least two panels are movable along the at least two support tracks in a first direction to open the door and in a second direction to close the door. The at least two panels stack horizontally with each other when the door is in the open position.

A telescoping door system includes a header that spans across a doorway. A trailing jamb and a lead jamb disposed a clear opening distance from the trailing jamb defines a clear opening of the doorway. A sidelite panel is coupled to the trailing jamb by at least one swing clear hinge; the swing clear hinge comprises a fixed gear portion intermeshed with a revolving gear portion. A slow slide panel and a fast slide panel move linearly within the header. The slow and fast slide panels are configured to create a first-sized opening when positioned in the header. The sidelite panel, the slow slide panel, and the fast slide panel are configured to pivot out of the header in a breakout position such that a trailing rail of the sidelite panel is disposed at least partially outside the clear opening and in front of the trailing jamb.

A fenestration assembly includes a glazing unit includes a pane spacer between exterior and interior panes proximate glazing unit edges. A fenestration frame is coupled around the glazing unit and includes a frame core extending around the glazing unit. The frame core includes a unitary core wall including a composite material that is hollow and extends continuously from a core interior face to a core exterior face. A metal glazing cap is coupled with the frame core. The metal glazing cap having a cap end indirectly engaged with the glazing unit along the interior pane, and the cap end is remote from the pane spacer. Each of the core exterior face, the pane spacer and the metal glazing cap are thermally isolated from each other with the frame core including the unitary core wall.

A telescoping door system includes a header that spans across a doorway. A trailing jamb and a lead jamb disposed a clear opening distance from the trailing jamb defines a clear opening of the doorway. A sidelite panel is coupled to the trailing jamb by at least one swing clear hinge; the swing clear hinge comprises a fixed gear portion intermeshed with a revolving gear portion. A slow slide panel and a fast slide panel move linearly within the header. The slow and fast slide panels are configured to create a first-sized opening when positioned in the header. The sidelite panel, the slow slide panel, and the fast slide panel are configured to pivot out of the header in a breakout position such that a trailing rail of the sidelite panel is disposed at least partially outside the clear opening and in front of the trailing jamb.

A guide pin support system may include: a first support plate; a second support plate pivotally attached to the first support plate; a first guide pin supported by the first support plate; a second guide pin supported by the second support plate and the second guide pin pivotable with respect to the first guide pin.

Interlock assemblies for sliding fenestration systems that provide for adjustment of the position and/or shape of the interlock assemblies and methods of adjusting the position and/or shape of the interlock assemblies are described herein. The interlock assemblies for sliding fenestration systems may be adjusted after installation to accommodate changes in the position and/or shape of the sides of building opening on which a stationary interlock structure is mounted.

A panel door system has at least two support tracks and at least two panels hanging from the at least two support tracks. The at least two support tracks are mounted to a support structure such that each support track is offset from a previous support track both horizontally and vertically. The least two panels are hung using hanging mechanism such that each panel is hung on a different support track. The at least two panels create a door. The at least two panels are movable along the at least two support tracks in a first direction to open the door and in a second direction to close the door. The at least two panels stack horizontally with each other when the door is in the open position.

A sliding door partition wall system, comprising: a plurality of mobile doors (2) telescopically between an opening condition in which they are mutually overlapped and arranged near a reference wall (6) and an opening condition in which they extend along a movement direction (A); at least one fixed door (3), stably arranged near the reference wall (6) and on which the mobile doors (2) overlap in the respective opening condition; said doors (2, 3) having respective peripheral frames (4); and a positioning element (9) of the mobile doors (2), configured to constraint each mobile door (2) along a direction (B) perpendicular to the movement direction (A), and to define an alignment condition of the frames (4) of the mobile doors (2) to the frame (4) of the fixed door (3) in said opening condition.
