Disclosed are a low track assembly and a sliding door. The low track assembly includes a track with first slide grooves, and pulleys located in the track. The pulley includes a support, a roller assembly, and a hanging clamp, where the support moves in the first slide groove by using the roller assembly, a first accommodating groove and an accommodating site that is perpendicular to and runs through the first accommodating groove are provided on the support, a second accommodating groove is provided on the hanging clamp, and the hanging clamp is located in the accommodating site; a stop wall is provided at a first end of the accommodating site, a second slide groove is provided on the stop wall, and the second slide groove extends in a height direction of the track; a threaded hole that runs through the hanging clamp is further provided on the hanging clamp.

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.

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.

The sliding door system includes a sliding door, displaceable along a running rail relative to a stationary activation member up to a closing position; which includes a door leaf equipped with an activatable sealing device including an extractable sealing strip and actuating element equipped with a transmission device including a transmission element; and includes at least two carriages, including a carriage body and running elements connected to the door leaf, and are held in the running rail displaceable in parallel to the longitudinal axis of the running rail; wherein the activation member and transmission device are arranged so that, when the sliding door enters the closing position, a force can be transmitted from the activation member via the transmission element to the actuating element in order to drive out the sealing strip. A stationary buffer device stops the sliding door in the closing position and includes the activation member.

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.

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 roller module is configured of a first material and the basic body of a second material. The first material conducts structure-borne sound in a first sound conducting range and dampens the structure-borne sound in a second sound conducting range. The second material dampens structure-borne sound in the first sound conducting range and conducts structure-borne sound in the second sound conducting range.

A sliding door roller for a sliding door includes a slide disposed within a housing and a truck assembly disposed within the slide. When the truck assembly is retracted within the slide, the truck assembly and the slide are at least partially engaged to as to restrict or prevent the truck assembly from dropping out of the housing and rotating within the housing. The truck assembly being disengaged from the slide via an adjustment fastener to move the truck assembly towards and extended position relative to the housing.

The present invention discloses a sliding rail type low-obstacle linkage shower room and an installation method thereof. The shower room includes an upper rail and a lower rail, a fixed glass, a primary shower glass and a secondary shower glass. The lower rail is correspondingly provided at the secondary shower glass. A sliding block unit is installed on the secondary shower glass. The sliding block unit includes a fixed portion, a sliding groove and a guidance sliding portion. The fixed portion is provided correspondingly to the secondary shower glass. The sliding groove is used for receiving the primary shower glass 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.

An anti-derailment system is described for a wheel which can roll on a track and is pivoted on a carriage which translatably supports a leaf of a piece of furniture. The system has a slider which is inseparably mountable or mounted on the track and is able to translate on the track independently of the carriage, and a constraint element for constraining the slider and at least one of the wheel, the carriage or the leaf to each other, so as to keep the wheel in condition of rolling on the track without derailing.

The present disclosure relates to a pulley device, a sliding door, and a sliding window. The pulley device includes: a pulley component including a pulley; a connecting component including a rocker, one end of the rocker being rotatably connected to the pulley component; and a housing including a bottom plate and two side plates. The two side plates are fixed to two opposed sides of the bottom plate, respectively, so that the bottom plate and the side plates jointly define a receiving cavity configured to receive the pulley component and the connecting component. A surface of the side plate facing the receiving cavity defines a receiving groove along a length direction of the side plate, and the other end of the rocker is received in the receiving groove and is capable of sliding along the receiving groove.
