  • Patent number: 10344527
    Abstract: A roll-up door (10) with slats (60) rolled on a reel (12) with spiral guides (32) that maintain a tangent between the reel (12) and the closure plane at the point of entry/exit so as to maintain a perpendicular entry and exit with the side guides (36) and reduce friction, increase speed, reduce noise and help keep self-aligning end caps tracking correctly. It can also eliminate hinges between slats and permit each slat to be removed independently, without disassembling the other slats.

  • Patent number: 9273513
    Abstract: The invention relates to a lifting door assembly comprising a lifting door, in particular a fast-moving industrial door, having a door leaf which in the closed condition of the lifting door covers a door aperture, and a door lintel sealing device disposed in the area of a door lintel and mounted so as to produce a sealing effect between the door leaf and the door lintel in a sealing position when the lifting door is in the closed condition. The lifting door assembly is characterized in that the door leaf is guided laterally such that in the open position, it is wound free of contact in the area of a door lintel, and in that in the sealing position, the door lintel sealing device rests on a horizontal lateral edge surface of the door leaf adjacent the door lintel. The invention further relates to such a door lintel sealing device. The invention allows to improve a lifting door assembly such that particularly reliable sealing may be obtained with it in the area of the door lintel.

  • Patent number: 6082431
    Abstract: A garage door bracing arrangement has a plurality of vertically extending door-stiffening column members, which are pivotally attached to upper mounting brackets affixed to garage building structure directly above the garage door opening. Lower mounting brackets are affixed to second ends of the column members and are anchored to the garage floor directly beneath the upper mounting brackets. The door-stiffening column members are configured as generally hollow, rigid, telescoping sections having longitudinal channels which retain fasteners that project from sides of the telescoping sections, so as to pass through holes in mounting brackets that affix the door-stiffening column members to the garage building structure, and deflection brackets that secure the column members to door panel hinge joints.

  • Patent number: 6076589
    Abstract: An articulated overhead gate for gate openings with particularly small drop heights between the upper edge of the gate opening that is to be closed and an adjoining overhead area or similar with a gate leaf consisting of several panels (3, 5) articulated successively in the direction of movement, which are driven by laterally arranged rollers (2) in first lateral roller rails (6), connected in an approximately vertical and thereby curved horizontal direction, excepting the upper panel (5) in closed position, which engages with its rollers (4) which, in this position, are arranged in the upper edge area (30), in second roller rails (7). Said roller rails are parallel to and located above the facing horizontal segments of the first roller rails (6), each segment having an end part (8) facing the gate frame, a first section (10) of which part is lowered only slightly in relation to the horizontal, and a second section (11) correspondingly inclining only slightly over 90.degree.

  • Patent number: 6047761
    Abstract: A universal overhead door system includes a pair of horizontal track members, a pair of vertical track members and a pair of track radius members interconnecting the horizontal and vertical track members. A pair of short radius members extend from the track radius members to guide uppermost rollers of an overhead sectional door. The short radius members terminate close to the top of the door opening and thereby eliminate the need to guide the uppermost rollers below the level at which the curved portion of the track radius members begin. The ability to install the short radius members when needed for smaller door opening sizes and low head room environments provides a universal track system for most overhead door installations.

  • Patent number: 6024155
    Abstract: A truck trailer door safety door stop is provided for preventing a truck trailer door from accidentally falling closed. The door stop may be retrofitted onto a conventional truck trailer door of the roll up type including a plurality of hinged panels which ride along rails by means of roller wheels. The door stop includes a glide member for guiding a bottom panel of the roll up door along the rail without engagement therewith. When the door is in a fully opened position, the disengaged bottom panel is pulled out of alignment with the rail and separated therefrom by means of a spring. In response to a sudden forward movement of the truck, which would normally cause such a door to accidentally close, the door will be forced directly rearward and be prevented from falling down the rail. A guide bar may be provided for supporting the bottom panel in a positive lock open position.

  • Patent number: 5620038
    Abstract: A garage door bracing arrangement for reinforcing the entire vertical extent of a multi-panel garage door against high velocity (e.g. hurricane-force) winds is comprised of a plurality of vertically extending door-stiffening column members. These door-stiffening column members are pivotally attached to upper mounting brackets affixed to the garage building structure directly above the garage door opening. Lower mounting brackets are affixed to second ends of the column members and are configured to be anchored to the garage floor directly beneath the upper mounting brackets. The door-stiffening column members are further attachable to deflection brackets that are mounted to the door panel hinge joints, so that the garage door panels are securely braced over the entire height of the garage door by an anchoring structure that prevents the garage door from being flexed off its guide tracks and becoming detached by the impact of or the vacuum created by intense winds.

  • Patent number: 5560658
    Abstract: The large overhead bi-fold doors of the present invention are hinged along a centerline and hung by hinges from the top of the door opening. A motor mounted inside and above the door opening is connected to one end of a cable, the other end of which passes around a pulley at the bottom of the door and then upwardly to a latching mechanism located beneath the horizontal hinge line of the doors. When the motor is activated, the cable pulls on a dog or arm connected to a shaft which also carries the hook of a latching device. The hook engages a strike attached to the frame of the building on which the door is mounted, and when the motor is activated, the cable pulls on the dog which disengages the hook from the strike and further tension on the cable by the motor raises the door to an elevated position.
