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.

A perimeter light blockout system for minimizing light leakage between light gaps such as, for example, between the sides of a covering (e.g., shade) of an architectural-structure covering and the interior side surfaces of a window frame, or between the covering and the outer surface of an interior wall is disclosed. The perimeter light blockout system including a light blocking device and a mounting element for coupling the light blocking device to the interior side surface of the window frame, or the outer surface of the interior wall. The light blocking device may include rear and front channel members. The mounting element may be a mounting extrusion. Alternatively, the mounting element may be a spring clip. In use, the light blocking device may be adapted and configured so as not to contact the covering as the covering moves between extended and retracted positions. The mounting element may include a degree of adjustment so that the light blocking device may be aligned with an out-of-skew window frame.

Methods and systems for reducing sound propagation between spaces divided by a retractable wall are disclosed. A retractable wall is configured to divide a space when deployed. An edge of the retractable wall is disposed into a track with a channel when the retractable wall is deployed. A bladder is configured to inflate when the retractable wall is deployed and to press the edge of the retractable wall. In this manner, sound propagation through any gaps is reduced.

The present invention relates to a gate with a gate panel, comprising several gate panel sections which are hingedly coupled to each other by way of hinges, where a hinge comprises two hinge panels of adjacent gate panel sections, at least one elongate drive means which is connected to at least one gate panel section, and at least one guide means which is suitable to guide the gate panel during its motion. In order to optimize the gate with regard to its installation space, in particular in the width and depth direction, and to ensure simple and inexpensive yet at the same time still reliable operation of the gate, it is proposed to arrange the elongated drive means at least in sections received in the gate panel section.

A retractable screen device for a framed opening employing a frame track fastened to each side support of the framed opening; the frame track forming a compartment for receipt of a guide rail with a decompression gasket positioned between the frame track and the guide rail. A screen mounted on a horizontally disposed rotatable shaft secured to a header of the opening has laterally opposed side edges with an elongated flexible protrusion secured along the length of each side edge. The guide rail receives and guides the screen protrusion along a longitudinal direction, and the decompression gasket allows the guide rail to traverse the frame track side walls to permit the screen to flex while maintaining a consistent tension on the screen. Vertical tension adjustment is provided by use of a biasing member coupled to the center axle that activates when the screen is deployed.

A perimeter light blockout system for minimizing light leakage between light gaps such as, for example, between the sides of a covering (e.g., shade) of an architectural-structure covering and the interior side surfaces of a window frame, or between the covering and the outer surface of an interior wall is disclosed. The perimeter light blockout system including a light blocking device and a mounting element for coupling the light blocking device to the interior side surface of the window frame, or the outer surface of the interior wall. The light blocking device may include rear and front channel members. The mounting element may be a mounting extrusion. Alternatively, the mounting element may be a spring clip. In use, the light blocking device may be adapted and configured so as not to contact the covering as the covering moves between extended and retracted positions. The mounting element may include a degree of adjustment so that the light blocking device may be aligned with an out-of-skew window frame.

The invention is a track system for a retractable wall. The track system includes rigid outer guide tracks and flexible inner track inserts that are connected to the guide tracks by means of flanges located on both. The flexible inserts include a channel that engages with a side edge of a retractable wall, holding the wall in place. The flexible nature of the track inserts allows the inserts to bend, which in turn allows the retractable wall to flex when force is exerted on the retractable wall without breaking the tracks or tearing the wall. When excessive force is applied, the channel of the flexible insert, the walls of which are thicker than the rest of the flexible insert, bend open, so that the side edge of the retractable wall disengages from the channel by means of an opening in the channel.

Roller doors made of flexible material have a number of uses, particularly for rapid access into cool stores. However, such doors require stiffening in the form of wind bars to prevent the doors blowing out in gusts of wind. The wind bars produce problems when rapidly closing a roller door, as the door blade of the roller door is rolled up onto a roller. And for doors in cool stores that are opened and closed hundreds of times a day, such problems are significant. The present roller door blade solves or minimizes the problems by fitting longitudinal spacer elements along the length of the door which act to provide space between adjacent layers of the door blade as it accumulates on the roller, allowing any wind bars of the door blade to be stowed on the roller without interfering or clashing with other wind bars.

A roll-up door including a flexible curtain having a front surface, a back surface, a first end coupled to a shaft, a second end opposite the first end, and first and second side edges extending between the first end and the second end, the flexible curtain being moveable between a retracted position wherein the flexible curtain is coiled around the shaft and a deployed position wherein the flexible curtain is uncoiled from the shaft. A first retention band is mounted along at least a portion of the first side edge of the flexible curtain, the first retention band including an inner surface at least partially facing towards the flexible curtain, an outer surface opposite the inner surface, a fixed edge attached to the flexible curtain generally parallel to the first side edge, and a free edge opposite the fixed edge and movable relative to the fixed edge.

This disclosure relates generally to a smoke screen apparatus for shielding humans from harmful exposure to smoke, noxious fumes, or contaminated air. For safety reasons the smoke screen must allow for manual egress through the screen using a release mechanism that can automatically recover to the protective state after egress.
