Abstract: A foldable cover of simple structure and light weight is provided. The cover consists of multiple cover sections which are connected by hinges so that they may be folded together. Each of the cover sections has a hole in its surface through which a cable extends, such that when the cable is pulled, the cover sections are folded together at one side of the opening. The cable is initially pulled from a height above the cover sections so that the first pair of cover sections are caused to buckle upwards and then fold together. Further pulling on the cable causes the remaining pairs of cover sections to buckle and fold one pair at a time. When the cover is being extended, a tension is maintained on the pulling cable so as to control the falling speed of the cover sections as they unfold. Hinges and wheels that are used on the cover and around the holes exhibit a low rotational friction, so that the cover may be opened and closed easily.

Abstract: For mounting a folding/sliding door, a support is connected to a hinge arm of a hinger mounted in the upper outer end area of an outer door leaf in a position in which the side of the retaining part that attaches to the hinge arm is located in the extension of the bearing part. The folding/sliding door can then be joined by its inner leaf via hinges, preferentially standard double-link hinges, to a side panel of the body. The pre-fitted support, already connected to the hinge arm of the outer door leaf, can then be introduced and locked into the guide channel together with its carriage part. First, the carriage part is swiveled through 90 degrees around the retaining part so as to position the carriage part within the longitudinal slot of the guide channel. The carriage part is then locked in place by turning the hammer-shaped head through 90 degrees by means of its supporting pin.

Abstract: A rapid access door system is provided wherein authorized individuals may pass through the door system and wherein unauthorized individuals are blocked from entering a secured area past the doors and are automatically rerouted to an unsecured area for further processing without blocking the door system and impeding the flow of other individuals entering the door system. The door system uses modular units employing sensing means and a specially configured door which door automatically provides the rerouting of persons in the system. The sensing means determines, among others, the number of persons in the system, whether the door is opened or closed, whether a person has exited the system to particular areas, alerting speakers and signage, with the above information being used in conjunction with the door system to provide a highly efficient and effective rapid access portal system.

Abstract: A foldable shutter for protecting sliding glass doors from storms and break-ins is formed of vertical panels hinged together. The panels are extruded with full length beads on both sides and are held together by long extruded hinge clips having separate channels into which beads of adjacent panels fit. These hinge clips are substantially longer than the panels and the ends are closed by closure members having pins extending into the channel and spacing the panels from the ends. These closure members support the shutter on rollers in an upper guide and guide the bottom of the shutter in a lower guide. The hinges have three separate functions--to hold the panels together, to support the shutters, and to hold the shutters in place in the guides. Locking end trim sections for the shutter are hinged to the end panels and are also longer than the panels for support and guidance.
