An anti-derailing device for a sliding door, including slide rollers on upper edges of two sides of the sliding door, anti-bounce rollers below the slide rollers, rail supporting bases on a fixed door in front of the sliding door, and a rail fixed on opposite outer sides of the sliding door and the fixed door and clamped between the rollers. Each roller includes a fixed part and a first adjusting part which includes a first eccentric roller combined with the fixed part, each roller includes a fixing part and a second adjusting part which includes a second eccentric roller combined with the fixing part, and each rail supporting base includes a positioning part and a holding part for holding the rail. By adjusting positions of the rollers and without pre-machined holes, the sliding door can operate balanced and smoothly and prevent the rail from derailing.

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.

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.

A method is described for preventing the derailment of a wheel (30) which can roll on a track (22) and is pivoted on a carriage which supports translatably a leaf (20) of a piece of furniture, comprising the steps of (i) inseparably mounting on the track (22) a slider (50) which can translate on the track (22) independently of the carriage, and (ii) constraining the slider (50) to at least one of the wheel (30), the carriage or the leaf (20) to keep the wheel (30) in condition of rolling on the track (22) without derailing.

A simple and effective way is achieved to anchor the wheel to the track.

An anti-lift tab in a roller assembly for a door that rides along a fixed rail that does not rotate relative to the roller assembly in use. The anti-lift tab protrudes from the bottom of a face plate with keys molded onto the back face of the plate which interface with keyways contained in a castellated nut and shaft component with internal screw threads. A threaded rod is inserted through the inner diameter of a bearing seated in the roller which rides along a fixed rail. The rod is screwed into the shaft side of the castellated nut and shaft component. A screw attaches the mated face plate and castellated nut shaft components to the roller assembly. In this arrangement, the face plate with the anti-lift tab protruding from its bottom will remain fixed and not rotate relative to the roller assembly during translation of the roller assembly on the fixed rail.

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 shower door comprises a movable door, wherein at least one rolling wheel is fixed on the movable door, and at least one limiting member is fixed on the movable door; the shower door further comprises a track, the track is arranged below the rolling wheel, a closer is fixed on the track, the closer comprises a clamping member and a middle portion of the clamping member is provided with a clamping mouth facing upwards; and the limiting member comprises a limiting block and an anti-bouncing block, wherein the limiting block is located above the track, the limiting block is capable of being clamped in the clamping mouth of the clamping member and the anti-bouncing block is located below the track.

Sliding door systems are provided herein. The sliding door systems include a sliding door having a panel base, a sill having a guide channel having a stop arranged within the guide channel, wherein the guide channel includes a first subchannel and a second subchannel, wherein the first subchannel is defined at least partially by the stop and wherein the stop defines a gap connecting the first subchannel to the second subchannel, and an anti-derailment system. The anti-derailment system includes a first member having a first end and a second end, wherein the first end extends into the first subchannel and the second end connects to the panel base and a second member attached to the first member, wherein the second member is positioned within the second subchannel of the guide channel.

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, wherein at least two mounting devices are provided for realizing respectively one mounting function of the roller carriage. Each mounting device includes at least one mounting element with a manipulation interface for applying a mounting force for performing a mounting movement of the mounting element. The manipulation interfaces of the mounting elements of the at least two mounting devices are disposed on a first side of the roller carriage, and a bearing device of the roller module for the displaceable affixing at the roller running path is disposed on the opposing second side of the roller carriage.

An elongated member for a shower door assembly includes a protrusion configured to be received within a channel of a header to slidably couple the elongated member to the header. The elongated member is configured to be slid within the channel between a first position to allow for a shower door to be installed onto, or removed from, the header and a second position to substantially impede upright movement of the shower door when the shower door is moved along the header.
