Insulated doors with restorable breakaway sections are disclosed. An example door includes a first panel assembly including a leading panel and a trailing panel. The leading panel is to be in substantially coplanar alignment with the trailing panel when the first panel assembly is in a normal configuration. The leading panel is to be angularly displaced out of coplanar alignment with the trailing panel when the first panel assembly is in a dislodged configuration. The example door further includes a tension member to connect the leading panel to the trailing panel. The tension member is to resiliently urge the leading panel and the trailing panel toward each other in a horizontal direction. The tension member is to resiliently urge the first panel assembly toward the normal configuration when the first panel assembly is in the dislodged configuration.

A guide system (1) for a sliding door (101) comprises a pair of guides (3, 4) opposite each other to receive the respective opposite edges (103, 104) of a door (101); lifting means (5) for switching the door (101) from a resting position to a sliding position; the lifting means (5) is configured to produce a magnetic field inside one of the guides (3, 4) so as to bring the door (101) from the resting position to the sliding position.

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.

A frame structure includes a frame body, a corner connector and roller mechanism arranged in a splice of adjacent side frames at a bottom of the frame body, and a guide mechanism clamped to a top of the frame body. A glass positioning slot is disposed on a first side of an inner side wall of a side frame of the frame body. A mounting slot is disposed on a first side of an outer side wall of the side frame of the frame body and used for fixing the guide mechanism or the corner connector and roller mechanism. The glass positioning slot is adjacent to the mounting slot along a lengthwise direction of the first side of the inner side wall. A sliding door is further provided.

A frame assembly, for use in window and door applications configured to retain a panel, comprising a frame with a cover assembly and a support assembly having a track assembly, and a sill assembly and a header assembly both interconnected to a securing surface. The cover assembly is interconnected to the support assembly. The sill assembly comprises a roller member disposed in supporting relation to the track assembly, and the header assembly is disposed in supporting relation to the support assembly so that the frame is movable relative to both the header assembly and the sill assembly. At least a portion of the frame comprises a predetermined thickness and a predetermined width. The predetermined thickness is substantially less than the predetermined width so that both cooperatively and concurrently enhance viewing through the panel and the frame's stability.

An autonomous grid storage system (1) arranged in a warehouse space (12). The autonomous grid storage system is divided within the warehouse space, for example on a single floor of said space, into a plurality of sub grids (10a/10b) separated by fire walls (18). One or more bridges (14) pass through openings in the fire wall to allow bin handling vehicles (210/301) to traverse between the sub grids. The openings (20) are provided with closable fire door (22).

The invention concerns a drive unit for moving a door relative to a door's opening. The drive unit comprises a drive motor and a wheel transmission assembly arranged for transfer of power to a drive wheel configured for engagement with a running surface for moving the door. The wheel transmission comprises a transfer wheel driven by the drive motor. A movable wheel carrier comprises a first running wheel and a second running wheel arranged in in engagement with the transfer wheel. The movable wheel carrier is arranged for displacement between a free wheel position where the first and second running wheel are arranged disengaged from the drive wheel for no power transfer to occur from the drive motor to the drive wheel, at least one running position where either of the first and second running wheel is positioned in engagement with the drive wheel for the transfer of power from the drive motor to the drive wheel.

A patio door assembly includes a panel with a glass unit, and a polymer frame including a bottom member with a sill platform. A support beam is coupleable to the bottom member over the sill platform. The support beam defines a first channel between a top surface of the support beam and a platform, defines a second channel between the platform and the sill platform, a slot defined in the platform of the support beam. A structural insert is insertable in an end of the support beam and can be positioned in the support beam such that the structural insert supports a setting block for the glass unit of the panel to facilitate transferring a weight of the panel to the sill platform. The structural insert inhibits deformation of the frame when the patio door assembly is exposed to a high temperature environment (e.g., a desert environment).

A system for managing opening and closing a pocket door includes a spindle, an actuator, and brackets. The spindle extends along a longitudinal axis between first and second ends, and is configured to be coupled to the pocket door. The actuator is coupled to the spindle and is configured to cause the spindle to move axially along the longitudinal axis. The brackets are connected to the spindle at each end and are constrained from longitudinal motion relative to the spindle. The brackets are configured to affix the spindle to the pocket door. A bushing system couples each bracket to the spindle and is configured to dampen impact between the spindle and the brackets. For example, the bushing system may include lobed elements, made of a rubber material, that engage each other to transmit azimuthal forces. In some embodiments, another actuator is included to improve cycle like and redundancy.

A fitting frame having improved prefabricated rails, the fitting frame being implemented so as providable on an interior wall surface and the like, and includes: an upper frame body and a lower frame body which have facing surfaces respectively facing the upper end portion and the lower end portion of a door frame, and which are extrusion-molded in a longitudinal direction; and rail assemblies which are respectively fastened to the facing surfaces of the upper frame body and the lower frame body, and which guide the door frame so that same is mounted and slides thereon.
