A steam sterilizer having a door movable relative to an opening between a first open position and a second closed position. A plurality of spaced-apart roller assemblies are aligned along edges of the door to align the door relative to the opening as the door moves between the open and closed position. Each of the roller assemblies are comprised of a cylindrical roller having an outer annual recess extending along the periphery thereof. The recess is dimensioned to receive a lateral edge of the door. The roller is mounted on a shaft and is movable against a biasing force axially along the axis of the shaft.

In example implementations, a track of a vertically stacking door is provided. The track includes a vertical track, a track coupling coupled to the vertical track, a first curved track portion coupled to the track coupling, a second curved track portion coupled to the track coupling, and a ramp coupled to the vertical track before the track coupling.

A door operator including an output shaft, a ball screw, a powered driver, and a yoke. The output shaft is configured to be coupled to a door. The powered driver is operatively coupled to the ball screw and configured to rotate the ball screw in a first rotational direction. The yoke is coupled to the ball screw and configured to translate in response to rotation of the ball screw. The yoke is configured to rotate the output shaft.

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 roller assembly includes a roller housing being at least partially disposed within an outer housing moveable relative to the roller housing and at least one roller wheel in a direction perpendicular to a rotational axis of the at least one roller wheel. At least one resilient member is positioned at an end of the outer housing, and includes a fixed termination section coupled to an end member of the outer housing, a compliant section extending from the fixed termination section, a curved engagement section, and a resilient section between the compliant section and the curved engagement section and pivotable about the compliant section. The at least one resilient member is flexible from a first position to a second position when the curved engagement section mates with an inner surface of a slot defining a bottom edge of a panel secured to the outer housing to provide a holding force between the resilient member and the inner surface of the slot.

Disclosed is a hidden shower door with a low-rail sliding assembly, including an upper rail assembly (10), a movable door assembly (20), a vertical frame assembly (30), and a bottom guide part (40), wherein the upper rail assembly (10) includes an upper rail (1010), a damping trigger (1020), and sliding assemblies (1030), and the sliding assemblies (1030) each are mounted in the upper rail (1010); the sliding assemblies (1030) each include pulleys (10311), pulley brackets (1060), adjusting screws (10312), a damper (1050), and a damper bracket (1040); the pulleys (10311) are mounted on the pulley brackets (1060). The two pulley brackets (1060) are connected and fixed to two ends of the damper bracket (1040) respectively, and the damper (1050) is mounted in a damper accommodating groove (1041) of the damper bracket (1040); the upper rail (1010) is provided with a first bottom plate (1011).

The present invention relates to a door operation system (1) for opening and closing an opening (2) comprising: a door frame (3) comprising a first frame section (4) at a first side (5) of the opening (2) and a second frame section (6) at a second side (7) of the opening (2); a door (8) arranged to be moved between a closed (C) and an open (0) position, the door (8) being movably connected to the door frame (3); a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed (C) position to the open (0) position and vice versa, and an elongated transmission member (19) extending along at least one of the first side (5) and second side (7) of the opening (2), wherein the drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11), the driven transmission member (18) being movably connected to the elongated transmission member (19) and arranged to interplay with said elongated transmission member (19) for driving the driven transmission member (18) along said elongated transmission member (19) by the elongated transmission member (19) at least partially wrapping around the driven transmission member (18), wherein at least one guide member (92) mounted to the door (8) is arranged to interplay with the elongated transmission member (19) for guiding the elongated transmission member (19) into contact with the driven transmission member (18), wherein the least one guide member (92) comprises a sliding surface (101) on which the elongated transmission member (19) is configured to slide, and wherein the sliding surface (101) has a curvature, which is configured to urge the elongated transmission member (19) to flex and follow the curvature.

A laundry appliance includes a cabinet and a door rotatably coupled to the cabinet. The door is operable between an opened position and a closed position. A door opening assembly is coupled to one of the cabinet and the door. The door opening assembly includes a motor coupled to a cam. The cam is operably coupled to an actuator arm.

A fitting frame having improved prefabricated rails, the fitting frame being implemented so as providable on an interior wall surface and the like, and includes: an upper frame body and a lower frame body which have facing surfaces respectively facing the upper end portion and the lower end portion of a door frame, and which are extrusion-molded in a longitudinal direction; and rail assemblies which are respectively fastened to the facing surfaces of the upper frame body and the lower frame body, and which guide the door frame so that same is mounted and slides thereon.

Proposed is a door hinge. More particularly, there is provided a door hinge which is conveniently assembled, has a minimized shape, and above all, enables a closing force to be applied to a door so that when the door is opened, high-temperature heat is inhibited from being released from inside an apparatus on which the door hinge is installed.
