The present invention is generally a movable barrier assembly that includes a screen garage door that may be remotely operated to open and close an entry to a garage, thereby facilitating ventilation, and preventing debris such as leaves, insects, etc. from entering the garage. In an exemplary embodiment, a screen assembly includes a first track running substantially parallel to a second track on which a garage door travels. A movable barrier operator that actuates the garage door and screen door may include a first motor to operate the screen door, and a second motor to operate the garage door. In exemplary embodiments, a single control unit is configured to operate both motors and thus operate each movable barrier.

A high-speed rolling gate comprising a door leaf in the form of a flexible curtain, lateral guides in which lateral edges of the door leaf are received, and a drive which generates a driving force for driving the door leaf, wherein the door leaf has an elastically designed terminating element on a forward edge which is tensioned between the lateral guides by means of laterally applied transverse force components. The driving force of the drive engages on the terminating element of the door leaf and provides the laterally applied transverse force components for tensioning the terminating element of the door leaf and a tension force component substantially directed in the movement direction of the door leaf for closing the door leaf.

A system for reversibly providing a wall, comprising: a first panel comprising first track followers on each of opposite side edges of the first panel; a first pair of tracks adapted to receive the first track followers and that are generally vertical on opposite sides of a space, each comprising: a top at a point overhead, and a lower point part-way to the floor of the space; a second panel comprising: upper second track followers on sides of the second panel near a top edge of the second panel, and lower second track followers on sides of the second panel near a bottom edge of the second panel; wherein, as the first panel is lowered, the first track followers ride in one of the first pair of tracks until at least one first track follower reaches the bottom of the one of the first pair of tracks, thus allowing the first panel, when lowered, to form a first portion of the wall; a second panel comprising: upper second track followers on each of opposite side edges of the first panel proximate to a top edge of the second panel, lower second track followers on each of opposite side edges of the first panel proximate to a bottom edge of the second panel; a second pair of tracks that are generally vertical on opposite sides of the space to be divided and generally parallel to the first set of tracks, each comprising: a top at a point overhead, a junction where a spur track separates from the second track, a spur track at a point part-way to the floor that angles over from the second pair of tracks to a point below and in vertical alignment the first pair of tracks, a bottom at a point at or above the floor, wherein the lower second track follower interacts with the toggle switch, as the second panel is lowered, to move the toggle switch from a first position to a second position, and wherein the lower second track follower interact with the toggle switch, as the second panel is raised, to move the toggle switch from the second position to the first position; wherein the toggle switch, when in the second position, diverts the upper second track follower from the second pair of tracks into the spur; wherein the bottom of the second track is in vertical alignment with the first track; wherein, as the second panel is lowered, the lower second track followers reach the bottom of the second pair of tracks and the upper second track followers reach the bottom of the spur, thus allowing the second panel, when lowered, to form a second portion of the wall; and a toggle switch at the junction of the second track having a first position such that a track follower in the second track will continue past the junction remaining in the second track and will move the toggle to

A tensioning device for a door operating system includes a pulley carriage on which a pulley of the door operating system is mounted for rotation, the pulley carriage being movable relative to a track of the door operating system. The tensioning device further includes an adjuster configured to move the pulley carriage relative to the track and thereby alter a level of tension in a longitudinal drive component of the door operating system, the adjuster of the tensioning device being accessible from an end of the tensioning device facing a track operator end of the door operating system. The tensioning device also includes a resilient member operatively engaged with the adjuster, the resilient member configured to provide damping of forces experienced by the longitudinal drive component.
