The door actuator generally has a receiving structure having a door carriage path; a first coil assembly and a second coil assembly both being mounted to the receiving structure along a common coil assembly plane and being longitudinally spaced from one another along the door carriage path by a spacing distance; and a door carriage being slidingly received by the receiving structure, the door carriage having a plurality of alternate-pole magnets provided along a magnet plane being parallel and spaced apart from the coil assembly plane, the first and second coil assemblies being operable to move the door carriage back and forth between the two ends of the rail.

A sliding rail low-obstacle linkage shower room include an upper rail and a lower rail, a fixed glass, a primary shower glass and a secondary shower glass. The lower rail is correspondingly fixed on a bottom of the secondary shower glass. A sliding block unit is installed on the lower rail. The sliding block unit includes a fixed portion, a sliding groove and a guidance sliding portion. The fixed portion is fixed on the bottom of the secondary shower glass. A bottom of the primary shower glass is inserted into the sliding groove to form a linkage. The guidance sliding portion is glidingly engaged with the lower rail. The linkage shower room has a simple structure which can be easily manufactured.

A guide assembly for a sliding shower door is provided with a bracket sized to be fastened to a shower door opening. The bracket has a first lengthwise retainer. A guide with a second lengthwise retainer is sized to be retained by the first lengthwise retainer of the bracket. The guide has at least one channel formed therein and is sized to receive a shower door pane within the channel for translation of the shower door pane relative to the guide.

A sliding door roller system comprises a roller housing comprising a pair of generally vertical side members and an integral base portion including a projection on an inner surface thereof, the roller housing at least partially disposed within an outer housing; at least one roller wheel rotatably coupled to the roller housing; an outer housing moveable relative to the roller housing and the at least one roller wheel in a direction perpendicular to a rotational axis of the at least one roller wheel; and a rotatable adjustment mechanism coupled to the roller housing and the outer housing. The adjustment mechanism is rotatable from an exterior of the outer housing and is adapted to index the outer housing relative to the roller housing in a plurality of height positions in situ under load of a panel secured to the outer housing.

An adjustable carriage assembly includes a body; a hinge pin disposed in a threaded first bore of the body, the hinge pin having a threaded end and a first longitudinal axis; a lock post disposed in a second bore of the body, the lock post having a second longitudinal axis; a torsion spring disposed around the lock post; and a retention pin disposed in a third bore of the body to retain the lock post in the second bore. A first extension portion of the lock post engages a flat portion of the hinge pin in a locked state. The lock post is operable to rotate about the second longitudinal axis to disengage the first extension portion from the flat portion and place the carrier assembly in an unlocked state so that the hinge pin is free to rotate and move longitudinally within the first bore.

A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The basic body is supported at the roller module to be displaceable along a direction of gravity (SKR) for a fine-tuning movement, wherein a first adjusting component for an adjusting movement is supported at the basic body to be movable. For a movement of the basic body along a direction of gravity in relation to the roller module when performing the adjusting movement, the first adjusting component is in operative connection with a second adjusting component of the roller module.

The present invention patent concerns the eccentric pulley and hardware assembly for closing spans with glass panels such as doors, boxes and room partitions. The eccentric pulley was developed with the purpose of allowing a greater amplitude of regulation during the assembly of tempered or laminated glass panels, achieving in a first version (10), a regulation range of 16 mm, that is, between 8 mm and +8 mm, and, in a second version (100), said eccentric pulley of apparent use, becomes possible to be regulated in a range of 8 mm, that is, between 4 mm and +4 mm, allowing optimization of installation and ease of assembly of the closing of spans with fastened and movable glass panels, especially with respect to the leveling adjustment of said panels in relation to the floor and walls.

The displacement device includes a guide carriage that is slidable along a running rail and that is pivotally connectable to a first separation element. The guide carriage includes a carriage body with a carriage head and a carriage foot, which carriage head and carriage foot are connected with one another by a connecting beam, wherein the carriage head holds at least one support wheel and at least two guide wheels and wherein the carriage foot is connected torque proof with a first end piece of a hinge lever, whose second end piece is pivotally held by a hinge shaft that is connectable to a sidewall of the first separation element.

A sliding door includes a low track assembly with first slide grooves, and pulleys located in the track assembly. Each pulley includes a support, a roller assembly, and a hanging clamp, where the supports move in the first slide grooves. Each pulley further includes a first accommodating groove, an accommodating site that is perpendicular to and runs through the first accommodating groove, a second accommodating groove, a stop wall at a first end of the accommodating side, a second slide groove in the stop wall, and the second slide groove extends in a height direction of the track assembly.

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.
