A sliding door assembly includes a door frame with a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill, and a primary sliding panel secured in the door frame. The top trim member includes a track configured to support a weight of the primary sliding panel and prevent the primary sliding panel from coming off the track. Other features include an interlock mechanism to limit relative movement using multiple sliding doors and a brake mechanism to secure the doors in position when the door handle is released. A drop window includes features to accommodate for manufacturing tolerances and box frame assemblies that are out of square.

A shower door assembly with translating glass door panels riding in a lower track and supported by an upper center guide with a locking mechanism providing that one glass door is locked in place while the other glass door is allowed to translate. A double bottom slider system and mechanism for a sliding door assembly allow the doors to translate relative to each other. A locking system located on the top portion of the lower track made up of an inner door gear element attached to a torque loading device with a protruding element in contact with the inner door panel meshed with an outer door gear element with a protruding element in contact with the outer door panel. The shower door assembly operates in the setting of sliding all glass shower door systems to lock one door in place while the other door is free to translate.

A sliding sash assembly for use as a door or window includes: (a) a frame defining a frame opening; (b) a pair of sashes mounted in the frame opening and slidable relative to each other along an opening axis between a closed position and an open position; and (c) at least one stop device including a housing and a pair of depressible stop members movably mounted in the housing. The stop members are spaced apart from each other along the opening axis. Each stop member is selectively movable independent of the other stop member between a retracted position in which the stop member is retracted into the housing and an advanced position in which the stop member projects from the housing for engagement with one of the sashes to restrict movement of the sashes relative to each other toward the open position.

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.

A drainage cap includes: a body part configured to be inserted to a drainage outlet; and a flange part provided at the body part, and including a notch and an opposing part at a peripheral portion of the flange part, the opposing part being configured to face a peripheral portion of the drainage outlet.

A door system includes a track, a sidelite panel, and a slide panel. The track spans across a doorway having a clear opening defined by a trailing jamb and a lead jamb. The trailing jamb includes a jamb face facing the lead jamb. The sidelite panel is coupled to the trailing jamb by at least one swing clear hinge including a fixed portion and a revolving portion. The fixed portion is offset away from the lead jamb with regard to the jamb face. The slide panel is operable to move along the track. The slide panel has an open configuration when positioned in the track. The revolving portion is at least partially offset away from the lead jamb with regard to the jamb face when the slide panel is in the open configuration. The sidelite and slide panels are configured to pivot out of the header into a breakout configuration.

An anti-derailment system is described for a wheel which can roll on a track and is pivoted on a carriage which translatably supports a leaf of a piece of furniture. The system has a slider which is inseparably mountable or mounted on the track and is able to translate on the track independently of the carriage, and a constraint element for constraining the slider and at least one of the wheel, the carriage or the leaf to each other, so as to keep the wheel in condition of rolling on the track without derailing.

A frame assembly with sliding panels is described. The frame assembly includes a frame having an upper section opposite of a lower section. The lower section of the frame defines a first channel and a second channel. A first sliding panel includes a first lower edge. A first panel support is removably engaged to the first lower edge. The first panel support includes a first holding member that engages to the first lower edge. The first panel support slides in the first channel. A second sliding panel includes a second lower edge. A second panel support is removably engaged to the second lower edge. The second panel support includes a second holding member that engages to the second lower edge. The second panel support slides in the second channel.
