The housing also has a second subassembly having a second pair of wheels, the second subassembly being configured so as to allow rocking of the second pair of wheels. The first and second subassemblies are independently vertically adjustable with reference to the housing. The present wheel assemblies may be of the type used to support a sliding door or similar, on a surface such as a track.

A sliding doors floor handling device (20) for sliding wooden doors (10) or glass doors (72), placed next to a wall (16) and provided at the bottom with a guide (82) combined with a pin (14) protruding from the floor (48), comprises a containment shell (26), substantially parallelepiped in shape, pardy open along the upper base, in which a fork-shaped frame (44) is arranged. The parallel sections (64) of the frame (44) are provided with a hole (52) for inserting a pin (54) that supports a wheel (46) designed to touch the floor (48) when rolling. The fork-shaped frame (44) is provided with one or more elastic sheets (60) secured to the shell (26).

A sliding window or door includes sash, a frame and an actuator, which includes a carriage. The carriage includes a slide mounted on the sash so as to enable a secondary sliding motion between a stationed position and a sliding position and vice versa. The carriage also a connecting portion fixed to the sash and associated with the slide so that the secondary sliding motion of the slide towards the sliding position determines a raising of the sash and the secondary sliding motion of the slide towards the stationed position determines a lowering of the sash. A rotating actuator is mounted on a rear head surface of the sash, and has a rotation axis parallel to said sliding direction. A rear command shaft is arranged along the rear head surface of the sash and operatively interposed between the actuator and the carriage for generating the secondary sliding motion.

A door support connector assembly includes a door rail assembly that engages the top back face of the door using a plurality of fasteners. A door rail provides a continuous track and two rail stops to inhibit the door from disengaging from the track and ultimately from the wall. A wall mount assembly includes two rail guide wheels which engage the continuous door rail track and these wheels contact the two rail stops when the door is in the open or closed positions. A plurality of fasteners affix the wall mount assembly securely to the wall. An adjustment knob is provided on the wall mount assembly to vertically adjust the two rail guide wheels concurrently against the door rail continuous track to ensure reliable performance of the rolling door.

The present disclosure relates to a window assembly having a ventilation function and a horizontal close-fitting function, and more particularly to a horizontal close-fitting window assembly for implementing crime prevention and security functions by preventing a window from being open even in a ventilated state with the outside in which the window is slightly open and conveniently opening the window. The window assembly having a ventilation function and a horizontal close-fitting function includes a window sash, a window frame in which the window sash is installed to slide, a handle rotatably installed on the window sash, a latch provided on a side surface of the window sash and operatively connected to movement of the handle to move in up and down directions, a latching guide that is provided on the window frame at a relative position facing the latch and by which the latch is or is not latched depending on a position of the latch, and a horizontal movement device provided on at least one of a top surface or a bottom surface of the window sash and operatively connected to the handle to cause horizontal close-fitting or horizontal close-fitting release of the window sash depending on movement of the handle, wherein the latching guide includes a first latching region positioned at an upper part, a second latching region located lower than the first latching region while being spaced apart from the first latching region, and a separation space provided between the first latching region and the second latching region, and a vertical central line of the first latching region and a vertical central line of the second latching region are displaced from each other, and when the latch is located in the first latching region or the second latching region, horizontal close-fitting or horizontal close-fitting release of the window frame is inducted, and when the latch is located in the separation space, the window sash is slidably moveable with respect to the window frame.

An adjustable guide device, which serves for guiding a sliding element, such as a sliding door, with a mounting body that is mountable on the floor, a guide member that is pivotally connected to the mounting part and is designed for interacting with the lower side of the sliding element, and a locking element, with which the connection between the mounting part and the guide member is fixable or releasable. The guide member comprises a guide body and a guide foot, which are connected with one another, which guide body comprises a guide column that is aligned along a guide axis (y) and which guide foot is seated on an upper side of the mounting body and is pivotally connected by a joint element to the mounting body so that the guide foot can be turned around a pivot axis (x), which is distant from the guide axis (y).

A sliding window or door includes sash, a frame and an actuator, which includes a carriage. The carriage includes a slide mounted on the sash so as to enable a secondary sliding motion between a stationed position and a sliding position and vice versa. The carriage also a connecting portion fixed to the sash and associated with the slide so that the secondary sliding motion of the slide towards the sliding position determines a raising of the sash and the secondary sliding motion of the slide towards the stationed position determines a lowering of the sash. A rotating actuator is mounted on a rear head surface of the sash, and has a rotation axis parallel to said sliding direction. A rear command shaft is arranged along the rear head surface of the sash and operatively interposed between the actuator and the carriage for generating the secondary sliding motion.

A guide and rail assembly and system for stabilizing a shower door and stationary panel of a shower enclosure are disclosed. The assembly includes an exterior slider bracket configured for mounting on top edge of stationary panel, an exterior slider guide block configured for mounting on top edge of shower door, and an interior slider bracket configured to be housed within a longitudinal channel of the exterior slider guide block such that exterior slider guide block sets atop interior slider bracket and is secured thereto. The assembly further includes a front housing plate configured for attaching to bottom edge of the shower door, a roller bearing component configured to be slidably disposed along top surface of bottom guard rail of shower enclosure, a rear housing plate, and a cover plate configured to be secured to the rear housing plate. Cover plate and rear housing plate are positioned opposite of bottom edge of shower door from front housing plate such that roller bearing component is slidably disposed therebetween front housing plate and rear housing plate in an assembled configuration.

A sliding door unit has a mounting frame and an active door panel mounted in and capable of sliding relative to the mounting frame. The active door panel has a face including a panel portion and a glazing portion. The glazing portion comprises less than 65% of a surface area of the face.
