The invention is an arrangement for moving fenestration panels, comprising fenestration panels (12a-12d) each having two guiding elements protruding respect to each of opposite guide sides, and two track constructions (5) having identical paths, each adapted oppositely arranged for guiding the two guiding elements.

In the arrangement the track constructions (5) are adapted to be arranged in a lower and upper structure portion, comprising first, second and third main track element (10a-10c) adapted to be arranged beside each other, and connector track elements (26a′-32b″) adapted for interconnecting the first and second main track element (10a, 10b), and the second and third main track element (10b, 10c), a track element-connecting pair (32a, 32b) of them is configured being suitable for separated transferring of the guiding elements of each fenestration panels (12a-12d) between the main track elements (10a-10c).

A sliding door assembly includes a track assembly defining a track surface and a slot; and a sliding door comprising a door body, a hinge rod, and a locking pin, each of the hinge rod and the locking pin extending from the door body and through the slot; wherein the sliding door is laterally slidable along the track assembly between a first position and a second position, and wherein each of the hinge rod and the locking pin slide laterally within the slot as the door slides between the first position and the second position.

A sliding door or panel system is provided. The system can have a roller assembly that is mounted onto a sill. The system can have a moveable door or panel with a blade extending from a bottom rail of the door or panel. The blade can rest on the rollers and the rollers facilitate the door or panel moving longitudinally along the sill. The sill can be installed below a top surface of a floor, making the system less visible. The system can include a brush insert that protects against debris entering the sill. The brush insert can be removed from the sill to allow access to the rollers.

A sliding door system includes an upper track; a lower track; a first sliding door comprising a first upper locking pin, a first lower locking assembly, and a first pivot assembly, the first pivot assembly engaging the upper track and the lower track, the first upper locking pin removably engaging the upper track, and the first lower locking assembly removably engaging the lower track; and a second sliding door comprising a second upper locking pin, a second lower locking assembly, and a second pivot assembly, the second pivot assembly engaging the upper track and the lower track, the second upper locking pin removably engaging the upper track, and the second lower locking assembly removably engaging the lower track.

A foldback door system for at least partially closing an opening having at least one plane, the system including at least two mutually pivoted panels movable between a closed condition relative to a frame having at least one jamb relative to which the at least two mutually pivoted panels are hung, the at least two panels including a lateral panel located closer to the jamb and an inner panel hinged relative to the lateral panel and the frame, the lateral panel being of a first dimension and the inner panel being of a second dimension different to the first dimension, the closed condition in which the at least two panels are in substantial alignment to at least partially close the opening and a fully open, foldback condition in which the at least two panels are substantially parallel with one another and lie at an angle of greater than 90° with respect to the at least one plane of the opening in which the at least two panels lie in the closed condition.

Example aspects of a shear plate for a window frame assembly, a window frame assembly, and a method for insulating a window frame assembly are disclosed. The shear plate for a window frame assembly can comprise a shear plate body defining an outer shear plate surface and an inner shear plate surface, the shear plate body defining a first end, a second end opposite the first end, and a pair of lateral sides extending between the first end and the second end; and at least one pair of shear plate holes extending from the outer shear plate surface to the inner shear plate surface, the pair of shear plate holes oriented such that a line running through a center of the pair of shear plate holes is substantially parallel to the first end and the second end.

A folding panel system that allows foldable panels, such as folding glass doors, to fold and move around segmented tracks. The system includes a trolley assembly. The trolley assembly can include a pair of dual roller assemblies spaced rigidly apart by a rigid guide member and supported by an overhead guide track. The rigid guide member is positioned outside of the guide track and moves lengthwise along the overhead guide track except between overhead linear track segments. A hinge extension is secured to and extends rigidly away from the rigid guide member vertically away from the guide track. This configuration holds the hinge extension at a constant angle with respect to the guide track. The hinge extension pivotably joins hinge leaves from adjacent panels hingedly joining the two panels.

A slide-and-swing wing system includes at least one rail profile. At least two wings, each displaceably mounted in the at least one rail profile via two support elements The at least one rail profile has a lateral outlet opening for unlatching a support element of a wing. One wing functions as a door leaf which, with all other wings in the latched state, is pivotable into the remaining opening. A closure mechanism makes it possible to prevent the door leaf from being opened and includes a drive, and also an operating part, via which the drive can be actuated. The door leaf is displaceable, via the drive, in the rail profile in the direction of the adjacent wing to such an extent that no support element of the door leaf is aligned with the outlet opening, thereby preventing a support element from coming out through the lateral outlet opening.

A sliding door assembly includes an upper track assembly; a lower track assembly; a sliding door laterally slidable along each of the upper track assembly and the lower track assembly, the sliding door comprising a door body, an upper locking pin, and a lower locking pin, the sliding door configurable in a locked configuration and an unlocked configuration; and an actuator operatively connected to each of the upper locking pin and the lower locking pin; wherein, in the locked configuration, the actuator simultaneously engages the upper locking pin with the upper track assembly and the lower locking pin with the lower track assembly to prohibit the sliding door from opening, and in the unlocked configuration, the actuator simultaneously retracts the upper locking pin from the upper track assembly and the lower locking pin from the lower track assembly to allow the sliding door to open.

A sliding door system includes an upper track; a lower track; a first sliding door comprising a first upper locking pin, a first lower locking assembly, and a first pivot assembly, the first pivot assembly engaging the upper track and the lower track, the first upper locking pin removably engaging the upper track, and the first lower locking assembly removably engaging the lower track; and a second sliding door comprising a second upper locking pin, a second lower locking assembly, and a second pivot assembly, the second pivot assembly engaging the upper track and the lower track, the second upper locking pin removably engaging the upper track, and the second lower locking assembly removably engaging the lower track.
