An indexing multi-panel door includes a leading door panel supported on a first track and moveable between open and closed positions, a trailing door panel supported on a second track and moveable between open and closed positions, a motion control track mounted to one of the door panels, a follower mounted to the other one of the door panels, the follower including a first distal end received within the motion control track, the motion control track including features to frictionally engage the first distal end, wherein when the leading door is moved between the open and closed positions, engagement between the first distal end and the features moves the trailing door panel along with the leading door panel, and allows slippage, wherein the leading and trailing door panels move relative to one another as the leading and trailing door panels are moved between the open and closed positions.

Systems and methods for providing a door seal system for top-hanging sliding doors. In some implementations, two angled mating surfaces are used, one angled surface on a fixed frame and one reversed angled surface on the slideable door panel. The slideable door panel slides directly parallel to the fixed door frame. A mating seal surface is created that is only in frictional contact for a small portion of the linear slide distance of the door panel. In some implementations, rather than placing two opposing angled seal surfaces, the sealing system has one angled surface on the fixed door frame. In such implementations, the sliding door panel is adjusted to be in a reverse angled orientation relative to the angled surface of the fixed door frame. Seal designs for the rear vertical edge of the slideable door panel are also provided herein.

A hybrid drive-thru door system that includes a door panel assembly movable between a plurality of operating modes. The door panel assembly includes a sliding door panel operable for movement between a closed position to at least partially cover a doorway opening and an opened position to at least partially expose the doorway opening. The sliding door panel has an upper sliding door panel member releasably attached to a lower sliding door panel member. The upper sliding door panel member is independently movable relative to the lower sliding door panel member in a window operating mode of the door panel assembly.

This invention provides sliding door enclosure assemblies for a framework structure, which uniquely enables equal lateral displacement of sliding doors, with the minimal engagement of a single door alone. More specifically, the sliding door enclosure assemblies of this invention comprise paired rotatable sliding doors, paired rotatable leaders, paired rotating conveyors, which conveyors are advanced by the paired rotatable leaders, guides which further comprise attachment regions to attach the paired rotatable sliding doors to the paired rotating conveyors and at least one interlocking rotatable movement regulator set of two elements, which rotate in equal and opposing directions, so that paired rotatable leaders operationally connected thereby promote lateral displacement of operationally connected rotatable sliding doors about the framework structure.

Apparatuses, such as shower door frame kits, for installing sliding shower door assemblies are provided. The apparatuses enable secure and convenient installation of the sliding shower door assemblies, while keeping water that may escape a shower area to a minimum. The apparatuses of the present disclosure also provide for efficient installation of the sliding shower door assemblies that can be completed with a single tool and/or in a single step. The apparatuses for installing sliding shower door assemblies may include one or more of a shower door header, a wall jamb, a shower header retainer, a shower door catcher, a roller assembly, a corner bracket, and a shower threshold.

A suspension holder and a frame unit thereof are provided. The frame unit includes a main segment, a suspension segment, and a holding segment. The main segment is in an elongated shape defining a longitudinal direction. The main segment includes a selecting portion, two long lateral edges, a first mating portion, and a second mating portion, the latter two of which are spaced apart from the selecting portion along the longitudinal direction. The suspension segment and the holding segment extend from the two long lateral edges of the main segment, respectively. The selecting portion selectively geometrically corresponds with the first mating portion or the second mating portion.

A sliding door system including a wall cavity between a first wall lining and a second wall lining, a door frame adjacent the wall cavity, a guide extending across the top of the door frame and the top of the cavity, and a door panel suspended from carrying means supported by the guide, the guide including a plate, and two wings extending from the plate to define a cavity between the wings and the plate, characterised in that the cavity is closer to a second end of the plate than it is to a first end of the plate and that the distance from the door panel to the first wall lining is greater than the distance from the door panel to the second wall lining.

A door device for the interior of a passenger transport vehicle, and a passenger transport vehicle having at least one door device. The device includes a double-leaf sliding door with a first door leaf and a second door leaf in one plane. The door device has an upper guide for the first door leaf and an upper guide for the second door leaf. The guides are parallel with one another, and at least the upper guide for the first door leaf is offset with respect to the plane of the first and the second door leaf.

The object of the invention is a door arrangement of an elevator, which elevator comprises at least an elevator car, an elevator car door with door panels and a suspension beam for the door panels, as well as a door motor and door coupler structure, and also landing doors, with door panels, of the floor levels and a suspension beam for the door panels, as well as a synchronization means and rollers for the door coupler. The suspension beam of the door panels of the elevator car is disposed below the motor of the door operator and the door coupler structure, and that the suspension beam of the door panels of a landing door is disposed below the synchronization means of the door panels and the rollers of the door coupler.

An adjustable header having a first header piece and a second header piece, which are attachable to each other by a connector.
