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.

An overhead roll-up door assembly for a vertically moving door to permit and prohibit access to an opening, the door assembly having a door panel with two faces and opposing marginal and lateral edges, and at least two wind locks attached proximate each marginal edge. The at least two wind locks extend away from one face of the door panel in a direction substantially perpendicular thereto, and are spaced apart vertically along each respective side edge of the door panel. The assembly further includes a drum for winding and unwinding the door panel to permit and prohibit access to the opening, and, a pair of opposing parallel side columns aligned and spaced apart such that each of the opposing side edges engage one of the side columns in a manner in which at least a portion of the side columns guide vertical movement of the door panel.

The enclosure comprises: a partition (1) of panels (2) provided with longitudinal grooves (3) and a space for mounting a door (6); and a door (6) comprising: an upper box (7); and two vertical posts (9) with vertical guides (30) for moving a closing element (10), in addition to longitudinal channels (15) defining passages, with the longitudinal grooves (3), for housing fastening elements (16, 17) that can be vertically moved between a position wherein the door (6) is held and a position wherein the door (6) is released. The door comprises means for ensuring peripheral tightness in the closed position.

A roll-up door with fall protection preferably includes a door web, a pair of guide tracks, a pair of lower track brackets, a plurality of upper track brackets and a door web roller. The door web includes a plurality of screen web panels and wind bars. Opposing ends of the door web are retained in the pair of guide tracks. A first wind bar is arraigned to be 42 inches off a floor to meet OSHA fall protection standards. The door web includes at least two upper wind bars above the first wind bar and at least one lower wind bar below the first wind bar. The pair of guide tracks are secured to a wall with the pair of lower track brackets and the plurality of upper track brackets. A top of the pair of lower track brackets are located at least 42 inches above the floor.

A base slat pry stopper, such as a base slat locking bracket, for locking a rolling shutter curtain covering an opening of a structure is disclosed. The base slat pry stopper may include a bracket base plate mounted to an opening bottom wall on an interior side of the shutter curtain, and a base slat engagement portion extending upward from the bracket base plate and above a top surface of the opening bottom wall. When the shutter curtain is unrolled to cover the opening, the base slat engagement portion engages the base slat to prevent the base slat from deflecting upward away from the opening bottom wall when a force applied from an exterior side of the shutter curtain causes the base slat to deflect toward the interior side of the structure and the shutter curtain. The base slat pry stopper may be permanently or removably installed.

A closure apparatus for covering a portal is disclosed herein. In various aspects, the closure apparatus includes a curtain assembly having one or more curtains and a spindle assembly mounted superjacent a portal on an exterior of the portal. The spindle assembly is operably engaged with the curtain assembly to extend the curtain assembly to cover the portal and retract the curtain assembly to uncover the portal. Channels disposed on lateral sides of the portal engage the curtain assembly when the curtain assembly is extended to cover the portal. Front channel members, which are pivotably connected to corresponding adjacent supports, pivot to release the curtain assembly from engagement with the channels upon application of sufficient force to the curtain assembly to allow egress or ingress through the portal when the closure apparatus is not operational, for example, during loss of power. Related methods of operation of the closure apparatus are also disclosed.

A guide is presented intended for use in a sunshade assembly of the type comprising a flexible sunscreen having opposed longitudinal edges and two opposed longitudinal guides each comprising at least two spaced guide legs for defining there between a guide channel for receiving therein and guiding corresponding ones of the opposed longitudinal edges of the sunscreen. The guides and longitudinal edges are provided with cooperating guide locking members and edge locking members for preventing the longitudinal edges of the sunscreen from moving out of the guide channels. The guide locking members are defined on separate parts engaging the guides.

A screen device comprising: a screen roller (1), having a screen (2), which can be rolled up and unrolled hereon and which on at least one lateral side is provided with a thickening (6), a motor (7) for driving the screen roller (1), which motor, at that end of the screen roller (1) closest to the thickening (6), is disposed at least partially in the screen roller (1), wherein the motor (7) is fitted so far into the screen roller (1) that the thickening (6), in the rolled-up state of the screen (2), is positioned at least partially closer to the screen roller axis (A) than any point on that part of the motor (7) that is fitted in the screen roller (1), which point is situated the furthest from this screen roller axis (A).

A track assembly including a channel section in a fixed track having a screen receiver receiving a portion of a screen therein and at least one spring inserted in the length of the channel section. The at least one spring has a pre-defined spring rate which is designed to allow movement of the screen receiver in the channel in a first direction and back, depending upon an amount of tension or force applied thereto, e.g., as a result of wind pressure due to inclement weather that is applied to the screen. The spring(s) may be compressed by the screen receiver in such instances that force is applied thereto, and the compressed spring is configured to force the screen receiver back in an opposite direction when force is reduced or released.

The invention relates to the field of side guides for screen devices for reliable screens. The invention furthermore concerns methods for mounting and removing the side guide.
