FIG. (2) shows an anti-barricade door assembly (1) having a door (2) hinged to a door jamb (3) about a first, vertical, hinge axis H1. The door (2) consists of a generally planar, wooden laminated construction, main or central part (2a) bounded by an outer or peripheral, metal (steel) frame part (2b) that extends only around three edges (upper and opposed side edges 2c, 2d, 2e) of main door part (2a) but, importantly, not around the bottom edge (2f), of the main door part (2a). The main or central door part (2a) is pivotably mounted on the outer or peripheral frame part (2b) about hinge axis H2, said door part (2a) being pivotable inwardly, in normal use, about axis H2 to allow access to the interior e.g. of a prison cell.

In a door and door frame construction the door is hinged to the frame by one or more hinged structures, each hinged structure comprising a convex-surfaced support associated with the door and a convex-surfaced support associated with the door frame, at least two resilient strip-like S-shaped hinge members passing partially round each support and together with the other member forming a letter x or figure 8 configuration as seen in a direction along the supports, respective means being provided fastening together the ends of the members alongside each support so that the members are tensioned round the supports, wherein towards the lower end of the construction each support is provided with a surface raised from the general surface of the support and in contact with the raised surface on the other support.

A hinge for the pivotable linking of a door leaf or lid to the carcass of a furniture piece having a door-related part attachable to the door leaf or lid and a supporting-wall-related part, which parts are pivotingly joined together in the manner of a four-joint hinge by two hinge links pivotingly attached to the door-related part on the one hand to the supporting-wall-related part on the other hand. The outer hinge link farther from the supporting wall is linked on the supporting wall side to a pivot piece pivotingly linked to the supporting wall-related part. The pivot piece is coupled operatively to the inner hinge link nearer the supporting wall such that the pivot axis of the outer hinge link on the supporting wall end has in the hinge-open position a minimum distance and the the hinge-closed position a maximum distance from the pivot axis of the inner hinge link at the supporting wall end thereof.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

The present disclosure provides an aircraft door system including an aircraft door configured to translate from a closed position to an open position. The aircraft door system further includes a plurality of door pressure stops positioned along a length of the aircraft door and a handle coupled to the aircraft door. A rotation of the handle causes a first translation of the aircraft door in an inward direction and a forward direction. The aircraft door system further includes a hinge system coupled to the aircraft door. An outward force applied to the aircraft door causes a second translation of the aircraft door in an outward direction and a forward direction. The hinge system causes the aircraft door to translate such that the aircraft door remains parallel to the aircraft fuselage throughout an entirety of the second translation until the aircraft door reaches the open position.

A door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.

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.

A corner fitting for disposing a door element on a center of rotation or an axis includes first and second fitting elements-, which, at least sectionwise, each include a locating portion for the abutment against the door element and are interconnectable while restraining the door element. A restraining area forms between the two fitting elements, into which the door element is insertable, and the fitting elements are formed such that a holding element is disposed between the two fitting elements. The holding element is displaceable in relation to the fitting elements and is at least partially rotatable about the center of rotation or the axis. The holding element is in operative connection with a connecting element, which serves for supporting the door element on the center of rotation or the axis.

The invention concerns a strap hinge (1) for a separating element. The separating element takes the form of a door, for example, in particular a swing door. The strap hinge (1) comprises two active units. The strap hinge (1) is provided with securing units (27 to 29), which are actively connected to a surface owing to a radial movement. The strap hinge further comprises pressure units (40, 43). The strap hinge (1) offers the same properties as a strap hinge which is provided with a hydraulic braking device.
