An easy-open safety gate for a barrier has a first door panel, a second door panel, a positioning assembly, and a locking assembly. The positioning assembly has a positioning base securely attached to a lower end portion of the first door panel, and an engaging member securely attached to a lower transversely bar of the second door panel and detachably engages with the positioning base. The locking assembly has a resilient locking member mounted in an upper end portion of the first door panel, and a locking housing pivotally mounted on an upper transverse bar of the second door panel and detachably engaging with the resilient locking member. No threshold is disposed below the safety gate. A user can unlock the locking assembly and rotate the second door panel with only one of his/her hands, which is convenient and safe for the user to open the safety gate.

A variable width gate adapted to be manipulated to secure the gate within the boundary of an opening, the gate comprising two gate members mounted for sliding movement with respect to each other and each having a lever associated therewith and a releasable locking member for locking the respective levers with respect to relative motion therebetween.

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.

An improved barrel bolt assembly and extensible gate comprising the same wherein the assembly includes a washer having at least one inward or outward projection annularly disposed about an internal periphery thereof, a fastener having a head portion and a shank portion extending therefrom, and a barrel having a head portion and a boss portion extending therefrom, wherein the boss portion is operative to receive the fastener shank portion and the barrel boss portion further includes at least one inward or outward projection annularly and complementarily disposed and formed with respect to the inner periphery of the washer, to receive and mate with the washer, whereby the washer and barrel interlock to prevent rotational movement with respect to each other.

A louvered panel assembly restricts the ingress of contaminants into an enclosure. The louvered panel assembly includes a first louvered panel, a second louvered panel, and a third louvered panel. The first louvered panel has a first plurality of louvers extending arcuately, downwardly, and outwardly from a first plate. The second louvered panel is coupled to the first louvered panel and has a second plurality of louvers extending arcuately, downwardly, and inwardly away from a second plate that is spaced apart from the first plate. The third louvered panel is coupled to the second louvered panel and has a third plurality of louvers extending arcuately, upwardly, and inwardly away from a third plate that is spaced apart from and extends approximately parallel to the second plate.

The invention relates to a security grille system (1) for securing a passage at least partly. The security grille (2) is arranged to be brought from an extended state, in which the grille (2) can block the passage at least partly, into a retracted state, in which at least a part of the previously blocked part of the passage is unblocked. The security grille (2) comprises a multiplicity of bars (4), preferably substantially horizontally extending bars (4), connected by means of multiple elongated connecting elements for interconnecting respective bars (4). The security grille system (1) further comprises a chain connected to the grille (2), preferably a chain being flexible in only one dimension and/or being roller chain, and at least one chain limiting (28) member for at least locally limiting movement of the chain (19), e.g. in a direction in which it is flexible, such as to counteract that one or more links of the chain can be substantially moved away from a regular route along which the links move when the grille (2) is moved from its extended state to its retracted state or vice versa.

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. A pre-framed collapsible gate may be secured to and supported by a framing system for installation within a wall, wherein the collapsible gate is adapted for storage within the framing system when not in use. The pre-framed collapsible gate may be vertically retractable and adapted to stow within a framing system installed within a wall and out of sight. The collapsible gate may include a counterbalance to maintain the gate within the framing system 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.
