A closure system may include a closure movable between an extended state and a retracted state. The closure may be configured to at least partially obstruct an opening in the extended state and allow access through the opening in the retracted state. The closure may include a first portion and a second portion opposite the first portion. The wherein the closure may deflect by a first deflection distance when a vertical force is applied to the closure. The closure system may include a strap coupled to the first portion of the closure. The closure with the strap coupled thereto may deflect by a second deflection distance when the vertical force is applied to the closure. The first distance may be at least 100 percent more than the second deflection distance.

A closure may include a door configured to seal an opening. The door may include a section with an internal cavity. The closure may also include a core within a first portion of the internal cavity of the section. The core may be configured to expand from a relaxed state to an expanded state and provide a seal between the door and an edge of the opening when the core is in the expanded state.

A roller shutter may include a rotatable drum; a shutter curtain including a series of three or more elongate slats pivotally interlocked in a longitudinal-edge-to-longitudinal-edge arrangement and arranged parallel to the rotatable drum, wherein a first and second longitudinal end portions of each elongate slat may be respectively aligned to form a first side border and a second side border, respectively, of the shutter curtain, wherein the first and second longitudinal end portions of each elongate slat may be respectively provided with at least one eyelet-structure which protrudes therefrom, whereby a first and second rows of eyelet-structures are formed along the first and second side borders; and at least a first cord and a second cord respectively strung loosely through all eyelet-structures of respective row of eyelet-structures, and each cord may be configured to confine all eyelet-structures of the respective row of eyelet-structures within a length of each cord.

A self-adjusting retractable screen with an adjustable bottom bar assembly is disclosed herein. The adjustable bar assembly comprises a bottom bar assembly, an adjustable arm assembly, and a pivot assembly. The adjustable arm assembly is pivotally engaged with the bottom bar assembly via the pivot assembly, which is disposed in the horizontal center of both the bottom bar assembly and the adjustable arm assembly. During the deployment of the retractable screen, while the bottom bar assembly remains level, one side of the adjustable arm assembly can pivot upwards when the side first contacts a high point of an uneven surface, i.e., floor. When the screen retracts with the adjustable bottom bar assembly off the uneven surface, the adjust arm assembly has means to return itself to a level position.

An apparatus includes a lamp assembly having a clamp assembly. The clamp assembly is configured to be securely attached to a section of a garage door panel.

A fastener overlay assembly at an interface between first and second curtain segments of a rolling smoke/fire curtain positioned at an opening in a structure, the curtain segments having leading edges affixed to a bottom bar and extend between opened and closed positions by winding on a barrel assembly, each curtain segment connectable to the other curtain segment by a fastener during unwinding. The overlay assembly has an overlay strip with a leading edge proximate a leading edge of the curtain segment(s); and a retractable overlay collector roller attached to a first end of the overlay strip and configured to allow the overlay strip to unwind from a collector roller synchronously with the winding and unwinding of the curtain segments, wherein the retractable fastener overlay strip is arranged, in its extended position, in front of or behind the fastener that connects the first and second curtain segments.

The present invention relates to roll-up wall and acoustic barrier system (608) which may include an elongated member (300, 670). The elongated member may include a front wall (302), a rear wall (303) spaced from the front wall, a bottom wall (304), a first top wall (326a) adjacent the front wall, a second top wall (326b) adjacent the rear wall, and a channel (86) between the first top wall and the second top wall. The channel may comprise a first side wall (86a), a second side wall (86b), a first ledge (86c), and a second ledge (86d). The first and second ledges may define a slot (88) between the first side wall and the second side wall. The elongated member may further comprise a conduit (466) disposed between the front wall (302) and the rear wall (303) that is connected to the channel via the slot.

The present invention is related to a roller blind comprising: a length of fabric having a first end connected to a roller tube; a bottom rail have a top piece and a bottom piece releasably secure to one another; a connector for attaching to a second end of the length of fabric; wherein the connector comprises a first retention means adapted to releasably secured to the bottom piece of the bottom rail.

A slat assembly may include a slat having a first and second receiving portion. The first and second receiving portions being a pair of bent portions forming an acute angle. The slat assembly may further include an insulation layer lined on the slat. The slat assembly may further include a retaining mechanism disposed on the insulation layer to press a first portion of the insulation layer into the first receiving portion of the slat and to press a second portion of the insulation layer into the second receiving portion of the slat such that the retaining mechanism may cooperate with the first and second receiving portions to hold the insulation layer between the retaining mechanism and the slat without puncturing or penetrating the insulation layer with fasteners. A roller shutter including the slat assembly. A method of manufacturing a slat assembly and a method of manufacturing a roller shutter.

A door assembly with a flexible door movable between a retracted position and an extended position and having interconnected elongate slats having two lateral ends to form respective lateral edges of the flexible door. An automatically-locking bottom bar connects to a bottom-most slat of the flexible door. The bottom bar has anchors extending from the lateral ends thereof, the anchors extending beyond the respective lateral edges of the flexible door. A pair of guide channels receives the respective lateral edges of the flexible door, each guide channel having a reduced width portion in a bottom portion thereof to receive a respective one of the anchors when the bottom bar passes into the bottom portion of the pair of guide channels, the reduced width portion being laterally spaced from a lateral end of each said guide channel so that the respective anchor is locked in each said guide channel.
