Conventional UPVC windows have casements which are pivotable and movable in a limited manner relative to the frame. It is desirable to be to move all the casements such that substantially the entire the frame is opened. This is achieved by providing a window (10) comprising a frame (20) including a head (22), a sill (24), the window further comprising at least first and second casements, wherein the first casement includes hinges (50) for rotating it relative to the frame, the hinges being movable relative to the frame along channels (120) provided in the sill and head such that the first casement is slidable within the frame, the first casement also including at least one guide (52) located on the upper and/or lower surface of the first casement distal from the hinges and movable within the respective head or sill channel as the first casement slides relative to the frame, the said at least one guide disengagable from the respective head or sill channel allowing the at least one guide to pass out of the respective channel thus allowing the first casement to be opened relative to the frame, the sill including a runner (140) on which the casement is slidable. In this way the first casement may be stacked adjacent the second casement at one end of the window frame after both have been pivoted open.

The present lift lock is employed on a gate that is swingable and liftable on a first axis. In a first position the lift lock is on the first axis and in a blocking position that prevents the gate from being lifted relative to a barrier having the gate. The lift lock is slideable away from the first position on the axis to a second position away from the axis where the lift lock is in an unblocking position, thereby permitting the gate to be lifted on the axis. The lift lock snaps into and out of the second position.

A leafless joint apparatus that couples an enclosure housing to an enclosure cover or door. Similar to previous hinge apparatuses, the leafless joint apparatus can include a knuckle and a pintel or pin to facilitate pivot operations (e.g., the cover pivoting open). However, the leafless joint apparatus does not rely on leafs that attach by means of fasteners (e.g., screws or the like) and therefore can facilitate sliding operations (e.g., the cover can slide open). Thus, the leafless joint apparatus can facilitate access to an interior of the enclosure by way repositioning the cover of the enclosure via a pivot or hinging operation or via a sliding operation that can partially or fully expose the interior of the enclosure and even, if desired, slide entirely off, decoupling from the enclosure housing.

A flat-type ventilation door-window structure includes a frame (1), a first movable sash (2) and a second movable sash (3). The first movable sash (2) and/or the second movable sash (3) can slide up and down in an opening (11) of the frame (1). A first guide device (300) and a second guide device (400) being respectively provided between the first movable sash (2) or the second movable sash (3) and the frame (1). The first guide device (300) and the second guide device (400) can guide the first movable sash (2) or the second movable sash (3) to change the sliding path. The flat-type ventilation door-window structure can block outdoor sound, rain and air, and improve sound insulation, water tightness and air tightness.

The invention relates to a refinement of a spindle drive (1), and to a louvered window or a louvered shutter having a spindle drive for moving louver elements such that applied return forces and return torques can be absorbed better, and in particular without placing a load on the drive motor. For this purpose, the spindle drive (1) has a specially designed return stop mechanism (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).

A door system includes a track, a sidelite panel, and a slide panel. The track spans across a doorway having a clear opening defined by a trailing jamb and a lead jamb. The trailing jamb includes a jamb face facing the lead jamb. The sidelite panel is coupled to the trailing jamb by at least one swing clear hinge including a fixed portion and a revolving portion. The fixed portion is offset away from the lead jamb with regard to the jamb face. The slide panel is operable to move along the track. The slide panel has an open configuration when positioned in the track. The revolving portion is at least partially offset away from the lead jamb with regard to the jamb face when the slide panel is in the open configuration. The sidelite and slide panels are configured to pivot out of the header into a breakout configuration.

A locking mechanism for a door panel to be positioned within and out of blocking relationship with an opening. Mechanism includes a deadbolt rotatably connected to the wall and having a curved configuration and a locking bracket connected to the door panel. The locking bracket extends from the door panel in an angular direction with respect to a plane of door panel. With door panel in a closed position and deadbolt in a first position, the locking bracket extends through the curved configuration. Deadbolt is in blocking relationship with the locking bracket in a direction along a plane of the door panel and is not in blocking relationship in a direction along the locking bracket. With door panel in closed position, deadbolt is in a second position not in blocking relationship with the locking bracket permitting door panel to move in a direction along a plane of the door panel.

A vehicle door structure includes a door lock unit configured to lock a sliding door and a swing door when the sliding door is in a fully opened state, and a lock detection unit configured to detect a locked state between the sliding door and the swing door by the door lock unit. The door lock unit has a locking pin disposed at a guide body, a locking pin biasing member configured to bias the locking pin toward the swing door, and a fitting section formed at a slide rail and fitted onto the locking pin. The lock detection unit detects the locked state between the sliding door and the swing door by detecting the locking pin being fitted into the fitting section.

A pivot block including a first part for holding a bolt of an associated folding panel, and a second part that is able to be fixed to a track so as to position the first part and the bolt at a location whereby the folding panel is able to pivot about pivot bolt, wherein the first part is moveable relative to the second part lengthwise of the track, for adjustment of the position of the pivot bolt.
