A barrier includes a frame and a gate engaged within the frame, the barrier has a first state and a second state, a length of the frame in the second state being smaller than that in the first state, and a length of the gate in the second state being smaller than that in the first state.

A ribbon-type device effects undulation of a curtain for gathering the same in the vertical or horizontal direction. A functional unit comprises two tapes of fabric, each of which extends in an undulating manner to form a plurality of alternating positively and negatively curved arcs. An arc of positive curvature of a first fabric tape is set so as to oppose an arc of negative curvature of a second fabric tape and an arc of negative curvature of the first fabric tape is set so as to oppose an arc of positive curvature of the second fabric tape. The two fabric tapes are joined to each other at each transition between an arc of positive curvature and an arc of negative curvature by means of tie-off stitching (tie-offs). A plurality of such tie-offs accommodate a pull cord of a curtain.

Described is a pallet including a base having a length extending between a first end and a second end opposite the first end and a width transverse to the length; and a cage removably coupled to the base.

A panel assembly including a panel that can be positioned in an opening, the panel including a plurality of locking members spaced apart along at least part of a length of and proximate to opposing longitudinal edges of the panel and a guide extending along either side of the opening, each guide including at least one locking flange extending along at least part of a length of the guide, wherein in use the panel is received in the guides so that the locking members selectively engage the flanges to limit lateral movement of the panel edges.

Provided is an adjustable barrier having a central hinge having a cylindrical post and an axis of rotation; a first expandable section coupled to the cylindrical post of the central hinge by at least a first connector; and a second expandable section coupled to the cylindrical post of the central hinge by at least a second connector. At least one of the first and second expandable sections is configured to articulate around the axis of rotation of the central hinge forming an articulation angle between the first and second expandable sections.

The invention relates to a double articulated device and system comprising at least one active element provided with an edge (M), with two points (M1) and (M2), where (M1) is different from (M2), a rotating element connected to the edge (M) and a rotating fixture positioned in the point (M1) of the edge (M) and connected to the rotating element, in which, during actuation, the active element simultaneously describes a rotational movement with an angle β around the rotating element, and a partial pivoting movement in the vertical plane around the rotating fixture, so that the point (M2) of the edge (M) describes an angle a between a value α.sub.max corresponding to the “open” position ES0 and a value α.sub.min which corresponds to an ES1 “closed” position of the device.

A collapsible gate may provide a temporary barrier to prevent movement between rooms, or to prevent access to a staircase, in a home or commercial building. The collapsible gate may be secured to framing material within a wall and adapted for storage within a wall cavity, such as a pocket door frame, when not in use. The collapsible gate may be vertically retractable and adapted to fit between two framing studs to stow within a wall cavity and out of sight. The collapsible gate may include a counterbalance to maintain the gate within the wall cavity when the gate is in the fully open position, and to assist in opening the gate when the gate is lifted from a closed position.

A magnetic track assembly including an elongate channel having an open side, an end wall, and two parallel side walls; a first magnet disposed within the elongate channel near an interior side of the end wall; a compartment defined within the elongate channel spaced from the first magnet; and a screen receiver disposed within the compartment and including a second magnet arranged facing the first magnet. In the magnetic track assembly, the first and second magnets are of opposite polarity and the screen receiver is loosely disposed within the compartment such that a magnetic bond is intact between the first and second magnets when the first and second magnets are close together and the magnetic bond is broken when the first and second magnets are pulled apart.

A closing element for roller shutters comprising a central portion designed to be arranged, in use, according to a closing plane of an access opening of a room to at least partly close the access opening, and at least two connecting portions located on opposite edges of the central portion, each of which designed for connection of the closing element with at least one other closing element. Each connecting portion extends about a respective axis and defines a cavity for housing a connecting bar. The connecting portion has an open profile so that the cavity is accessible transversely to the axis.

A flood-protective ventilation louver includes a window frame assembly, slat assemblies, a transmission mechanism, and a buoyance switch assembly. During flooding, external water passes through the window frame assembly into the buoyance switch assembly, such that the buoyance switch assembly is caused to release the transmission mechanism from constraint to thereby allow the slat of each of the slat assemblies to oscillate downward automatically and thus automatic closing is realized.
