The invention relates to a windbreak system formed by a set of independent, folding panels that move longitudinally along an upper guide rail and another, lower guide rail and a non-movable folding door, in which each panel and the door include a rotating shaft and folding shaft. The panels are moved manually and do not have rollers, the entire weight of the panels resting on two strips of self-lubricating polymer inserted into slots in the lower rail.

The present invention relates to a double breakout sliding door system for use in retail and other buildings. The system includes left and right doors that are configured to slide open and closed and also breakout in two directions (outward and inward) when a force is exerted on the doors in order to, for example, allow customers and employees to exit a building in the event of a fire and to prevent damage to the doors in the event that a user pushes on them when they are closed. The system also includes a leveling system configured to keep the doors level when they breakout and a ball detent mechanism to alert the user to the proper position of the doors.

The present disclosure is generally directed to a method of operation for a convertible door system including a door accessible compartment having a moveable dividing wall that substantially divides the compartment into a first and a second sub-compartment. A first door assembly, configured to allow access to the first sub-compartment, is disposed between a first of two opposing sidewalls and the moveable dividing wall. A second door assembly, configured to allow access to the second sub-compartment, is disposed between a second of the two opposing sidewalls and the moveable dividing wall. A first and a second hinge assembly are adapted to rotationally join the first and second door assembly to respective opposing sidewalls. A third hinge assembly is adapted to rotationally join the moveable dividing wall to either the first door assembly or the second door assembly.

A closure mechanism for an electromagnetically sealed measuring station, which comprises a test chamber, a door for closing the test chamber, and an electromagnetic seal, which is fitted to a door frame of the test chamber. The door is moved initially in a linear manner away from the test chamber and after that pivoted in a rotating movement. The closure mechanism according to the invention then seals a measuring station electromagnetically if an electromagnetic seal is fitted in a peripheral groove in the doorframe of the test chamber, and the door provides a peripheral rebate, which engages in the groove in the doorframe.

The present invention discloses a new type of sliding door railing and, during installation, the first connecting mechanism and the second connecting mechanism are spaced in opposite direction fat the installation position, and then the opposite sides of door railing body are detachably and pivotally connected to the first connecting mechanism and second connecting mechanism, respectively, the connection between the door railing body and the first connecting mechanism can be disconnected, and the door railing body can be forced to swing for door opening and closing, with the connection position between the door railing body and the second connecting mechanism as the rotation center; the connection between the door railing body and the second connecting mechanism can also be disconnected.
