A rail system comprises: a guide rail; a plurality of stationary electromagnets mounted in the guide rail; and a carriage having a plurality of wheels configured to travel along the guide rail. The wheels are magnets. Movement of the carriage along the guide rail is brought about by a fluctuating magnetic field generated by the stationary electromagnets acting on the wheels.

The disclosure relates to a revolving door mounting arrangement (1) for mounting a drive ring (2) of a revolving door (4), the mounting arrangement (2) comprising: at least one hook element (6) configured to be pivotably connected to a wall element (8) of the revolving door (4); and at least one connecting part (10) of the drive ring (2), which at least one connecting part (10) is configured to pivotally displace the at least one hook element (6) during mounting of the drive ring (2), and which at least one connecting part (10) is configured to rest on the at least one hook element (6) in a mounted condition of the drive ring (2). The hook element (6) comprises: a first surface (12) configured to permit the at least one connecting part (10) of the drive ring (2) to slide on and along the first surface (12) during mounting of the drive ring (2) for pivotally displacing the at least one hook element (6); and a second surface (14) configured to receive the at least one connecting part (10) of the drive ring (2) in the mounted condition of the drive ring (2). The disclosure further relates to a revolving door (4) comprising a drive ring (2). The disclosure further relates to a method for mounting a drive ring (2) of a revolving door (4) by means of a revolving door mounting arrangement (1).

A slide member having a slide surface coated with a lacquer including a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide member with low friction.

A door actuator for opening and/or closing a door, includes a fluid housing with an inner compartment, which is filled with fluid, in particular hydraulic oil, a fluid housing opening in the fluid housing for draining the fluid at thermal overload, a thermally activatable valve for opening, which closes the fluid housing opening, and a collecting device, which is disposed outside the fluid housing opposite the fluid housing opening, forms a collecting space for the fluid, is open towards the fluid housing opening, and includes at least one drain opening for draining the fluid from the collecting space.

A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second direction and assist the spring in closing the door.

A locking assembly for a non-pivotable door is provided. The locking assembly comprises a spacer plate defining a spacer plate bolt void and a strike plate defining a strike plate bolt void. The spacer plate and strike plate are to be coupled to one another and further fixedly coupled to the non-pivotable door, such that the spacer plate bolt void and the strike plate bolt void are aligned. The locking assembly further comprises a locking mechanism and a housing, which is configured to receive and contain the locking mechanism. The locking mechanism comprises a latch bolt that is moveable between a retracted position within the housing and a deployed position. In the deployed position, the latch bolt extends outwardly from the housing and into each of the spacer plate bolt void and the strike plate bolt void, thereby locking the non-pivotable door to the housing.

A multifunction securing mechanism for a compartment closable by a door and includes a key cylinder, a latching assembly which may be a two-point latching assembly movable between a latching and an unlatching position, a rotatable member configured for a lazy-cam function connecting the key cylinder and latching assembly, at least one catch located on a surface adjacent the outside of the door, and a bar pivotally mounted to the outside of the door and movable between a first closed position and a second opened position. A first release mechanism is located on an interior side of the door for changing a positon of the latching assembly, and a second release mechanism is located on the interior side of the door for changing a position of the bar, both for allowing a user to open a latched and secured door from the inside.

Disclosed herein is a roller assembly for a sliding panel, the roller assembly including at least one roller sub-assembly having at least one roller wheel, the roller sub-assembly comprising at least one pivotal arm and a roller wheel rotatably mounted to the arm, wherein one end of the arm is configured for pivotally attachment to the support to permit the arm and roller wheel to pivot relative to the support in a vertical plane and the opposite end of the arm has resilient suspension means configured to allow resilient pivotal movement of said opposite end relative to the support when a force is applied to the roller wheel.

Described is an electronic delivery door for permitting passage of an object between an interior and an exterior of a structure through an opening defined in the structure, the delivery door comprising: a door panel; a hinge assembly including: one or more hinges for securing the door panel within the opening of the structure and for permitting the door panel to move between a closed position and an open position by rotation of the one or more hinges, wherein: in the closed position, the opening is covered by the door panel; and in the open position, the one or more hinges have been rotated to permit passage of objects through the opening; and an electronic security device configured to selectively permit opening of the door panel.

A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.
