A method for obtaining a vertical or horizontal profiled element for the interconnection of plasterboard panels to walls, in particular to plasterboard walls that can be applied to in-wall frames for retractable sliding doors or for the provision of drywall dividing walls.

The method entails a continuous machining of a metallic lamina by punching or drawing or rolling obtained by using two rollers, one acting as a die and the other acting as a punch, so as to obtain on the metallic lamina a plurality of holes, which are uniformly distributed according to a series of mutually parallel rows.

A secure sliding closure having a modular frame and one or more sliding door is described. The modular frame defines at least one secure cavity and a portal and comprises a main frame and at least one door frame. The main frame comprises at least one frame upright spaced apart from at least one portal upright and a respective at least one top plate extending between the at least one frame upright and the at least one portal upright. The at least one door frame comprising a locking side upright spaced apart from a secure cavity upright and a door frame top plate. The modular frame defines at least one secure cavity and defines a portal. The one or more sliding door comprises a sliding leaf and a sliding leaf covering, the covering comprising one or more sliding door security panel.

A drop down seal is provided which has a channel-shaped external support profile configured to be fixed to a base of a panel of a door or window, a rod-shaped support element slidably housed in the channel-shaped external support profile and a movable element connected to the rod-shaped support element by a parallelogram articulation mechanism allowing the movable element to move in height between a raised rest position and a lowered working position. The movable element, when in the raised rest position, is also operationally and removably connected to the channel-shaped external support profile. The rod-shaped support element, at a proximal end thereof, forms, or is provided with, a laterally protruding control portion configured to be engaged by a trigger base fixed to an abutment surface.

A pocket door frame includes a stud having a first section, a second section, and a third section. The first section is perpendicular to the second section, and the third section is perpendicular to the second section. The first section includes a first opening. The stud also includes a second opening located at least partially in the second section and at least partially in the third section. The second opening is at least partially aligned with the first opening so as to provide access to the first opening through the second opening.

A sliding door includes a bar that is movable in the closing and opening direction of a door leaf the sliding door. When the sliding door is in a closed state, the door separates a first space from a second space. A door frame in which the door is mounted has a bar catch, wherein the bar engages in the bar catch when the door leaf is in the closed state. The engagement can be released by movement of the door leaf, and therefore movement of the bar, in the direction of the normal of the door leaf plane.

A sliding door system for inline closure of an opening in the wall of a structure, which may be a building or an item of furniture, for example, that includes a door panel, a guiderail assembly, and a guiderail coupled to the wall mount via a plurality of doubled-hinge assemblies that together serve to allow the guiderail to pivot towards and away from the wall, and includes a stop on the guiderail that serves as a catch, or cam, that causes a closing force on the door panel to be transferred to the double-hinge assemblies and to cause the door panel to be pulled into inline closure in the opening.

A secure sliding closure having a modular frame and one or more sliding door is described. The modular frame defines at least one secure cavity and a portal and comprises a main frame and at least one door frame. The main frame comprises at least one frame upright spaced apart from at least one portal upright and a respective at least one top plate extending between the at least one frame upright and the at least one portal upright. The at least one door frame comprising a locking side upright spaced apart from a secure cavity upright and a door frame top plate. The modular frame defines at least one secure cavity and defines a portal. The one or more sliding door comprises a sliding leaf and a sliding leaf covering, the covering comprising one or more sliding door security panel.

A bracket for connecting a first extruded member having spaced and generally parallel extrusion fins to a second member. The bracket comprising a base plate, a longitudinal wedge element configured to be inserted in between the extrusion fins, an extrusion fin receiving channel to receive a first extrusion fin of the first extruded member, fastener receiving apertures through the base plate to receive a fastener to rigidly couple the bracket to the first extruded member, and a deformation cavity adjacent the fastener receiving aperture configured to receive a deformed extrusion portion of the first extrusion fin. The fastener receiving aperture is located on the base plate such that the deformed extrusion portion is forced into the deformation cavity and at least partially out of the extrusion fin receiving channel to form a rigid connection in a deformed condition when a fastener is located in the fastener receiving aperture.

A lighting device includes a first light source to emit first light; a diffuser to receive the first light and emits first scattered light; and a frame to support the first light source and the diffuser. The diffuser includes nanoparticles, and guides the received first light, scatters it with the nanoparticles, and emits it as the first scattered light. The diffuser includes an incident surface to receive the first light, a first surface on which an emission surface to emit the first scattered light is formed, and a second surface opposite the first surface. The incident surface is at a first edge portion of the diffuser, the frame is opened to expose at least a portion of a region on the first surface of the diffuser in which the emission surface is formed and a region on the second surface corresponding thereto.

Passenger seating comprises rows of seats with a door assembly at the end of each row for improving a seat occupant's privacy. The door assembly includes a door that slides into and out of a base in a primary mode of operation, and which supports a secondary mode of opening. The secondary mode may involve pivoting on hinges. A latch is provided to prevent the door from being opened routinely in the secondary mode. The door assembly is also capable of retracting with respect to the adjacent seat to improve access.
