The disclosure relates to a sliding door operator system (1) for opening and closing an opening (2), comprising: a track (3) configured to be mounted at an upper part (21) of the opening (2), one or more sliding door(s) 10 slidably connected to the track (3) and comprising a door leaf (4) configured to be moved along the track (3) between an open (o) and closed (c) position, and a drive unit (5) mounted on the door leaf (4), moveably connected to the track (3) and arranged to move the door leaf (4) between the closed position (c) and the open position (o). The disclosure further relates to a drive unit (5) for moving a sliding door leaf (4) between an open and a closed position (O, C) and a control system (11) for regulating one or more sliding door (10).

An apparatus for moving sliding doors and wardrobe doors fixed to the inner face of the top of a door (10) comprises at least one carriage (34) and at least one braking device (20) with a slider (22) pulled by at least one coil return spring (24). The door is hung from a beam made up of two extruded profiles (12), (14), the first of which is fastened to the wall with screws (15) and relative plugs; the second extruded profile (14) is fastened to the first profile (12) with snap-in couplings. These coupled profiles define a cavity (16) in which the braking device (20) is housed and stabilised with screws (18), fixed on a cantilevered bracket (26) of the second extruded profile (14); the latter defines a sliding track (28) for the wheels or bearings (30) of the carriage(s) (34), fixed to the door (10) at a recess (32).

An exemplary closure assembly includes a rail assembly and a door assembly movably mounted to the rail assembly. The door assembly includes a rotary damper having a pinion, and the rail assembly includes a rack member operable to engage the pinion. As the door moves from first position to a second position, the rack member engages the pinion, thereby causing the pinion to rotate in a first rotational direction. The rotary damper resists rotation of the pinion in the first direction, thereby slowing movement of the door toward the second position. The rotary damper may be a one-way damper that does not resist rotation of the pinion in a second rotational direction such that the rotary damper does not resist movement of the door from the second position toward the first position.

An apparatus for moving sliding doors and wardrobe doors fixed to the inner face of the top of a door includes at least one carriage and at least one braking device with a slider pulled by at least one coil return spring. The door is hung from a beam made up of two extruded profiles, the first of which is fastened to the wall with screws and relative plugs; the second extruded profile is fastened to the first profile with snap-in couplings. These coupled profiles define a cavity in which the braking device is housed and stabilised with screws, fixed on a cantilevered bracket of the second extruded profile. The latter defines a sliding track for the wheels or bearings of the carriage(s), fixed to the door at a recess.

A sliding door includes a door panel that has a first face, a second face that is opposite to the first face, and a top edge that defines first and second raised portions of the door panel and an open space that extends between the first and second raised portions. The sliding door includes a plurality of rollers affixed to the door panel by first and second mounting assemblies. Each of the plurality of rollers has an axis of rotation that is normal to the first face of the door panel. The sliding door includes a soft-close assembly secured to the first and second mounting assemblies at opposing ends thereof, such that the soft-close assembly is positioned within the open space between the first raised portion of the door panel and the second raised portion of the door panel.

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 gate opener assembly is comprised of a gate and an anchor assembly having a platform. A plurality of track assemblies on the platform provide a track on which the gate may slide from a first position (closed) to a second position (open) and any position in between. A guidepost having a “Shepherd's hook” configuration guides the gate as the gate passes therethrough. A pair of rollers within the interior of the top of the guidepost makes continuous contact with each side of the top of the gate both while the gate is stationary and in motion. A gate opener controller contains the required electrical connections to fully the operate gate opener assembly. Subterrain anchor supports provide the necessary support for the gate opener assembly. An alternative embodiment accommodates nontraditional configured gates. Installation of the gate opener assembly is performed by do-it-yourselfers in minimal time.

A corner support assembly for metal framed doors reinforces mounting of a metal door, so that the door molding easily attaches to extruded vertical and horizontal frame members of the corner support assembly. A top wall of the frame members with guide lines and molding that sits into a snap-fit mating relationship with corresponding frame members; thereby negating the need for notching. A heavy shear block provides structural integrity. The shear block abuts the intersection of the horizontal and vertical frame members, sliding between molding grooves in the vertical frame member. The shear block and horizontal and vertical frame members are secured into place with at least one of: a shear screw and a plug weld. An elongated threaded bolt reinforces connections between the horizontal and vertical frame members. A rubber glass setting block rests adjacent to the top wall of frame members to receive a glass pane.

An arrangement includes a rail profile and a running carriage movably mounted relative to the rail profile in the longitudinal direction and to which a sliding door can be fastened. The running carriage has a rolling body, and the rail profile has a running surface extending in the longitudinal direction of the rail profile and supporting the rolling body. The rolling body is displaceable on the running surface transversely to the longitudinal direction of the rail profile. Therefore, the running carriage can be pivoted about a pivot axis extending substantially parallel to the longitudinal direction of the rail profile. The rail profile has a vertical web extending in the longitudinal direction and oriented substantially perpendicularly to the running surface. The running carriage can be pivoted about the pivot axis such that a distance from the vertical web increases under loading by the sliding door.

An anti-lift tab of a roller assembly that rides along a fixed rail in use. The anti-lift tab protrudes from the bottom of a face plate having keys molded onto the back face of the face plate which interface with keyways of a castellated nut and shaft component having internal screw threads. A threaded rod is inserted through a bearing seated in the roller assembly. The rod is screwed into the castellated nut and shaft component. A screw attaches the face plate to the castellated nut shaft component and to the roller assembly.
