Abstract: A door having a door body that can be lifted, along a predetermined path, from a closed position in which it closes a wall opening into an open position in which it is located substantially overhead, the door body having two, three or more door body elements arranged one on top of the other in the closed position, is modified according to the invention in that a lower edge of the door body in the closed position and trailing during the lifting can be lifted separately, when the door reaches the open position, by a pivoting movement of a lower door body element having said edge in a lifting direction with respect to a door body element situated above it in the closed position relative to the predetermined path.

Abstract: A method for producing a coated structural element for exterior applications in the door and gate industry, such as for a sectional gate panel, an overhead door, a door, or a structural element for a facade with an integrated gate and/or integrated door, in which a relative movement between a starting material designed for producing the structural element and a coating device is generated along a feed direction, and to a coating mass that is applied to the starting material by the coating device along a coating direction that runs transverse to the feed direction and preferably approximately perpendicular to the surface to be coated.

Abstract: A structural element for the fabrication of a panel of a sectional door, which is movable between a closed and an open position along a predetermined pathway. The sectional door possesses a shell, generally of metal, having two mutually parallel sides, bent back on themselves, thus essentially creating structural elements aligned somewhat perpendicularly to the predetermined pathway. When in the closed position, the shell is characterized by forming an outer door surface which is external to the space to be closed, and forming an internal door surface opposed thereto.

Abstract: Embodiments of the invention relate to a method for producing structural elements exposed to the effects of weather, such as metallic structural elements, in particular sectional door panels, roll-up door slats or the like, in which method the structural elements which may have already been provided with a base coating, are imprinted.

Abstract: A gate includes a gate leaf which is movable between a closed and an open position, and a plurality of gate leaf elements, which are tiltable. The gate leaf includes a door leaf which is swingable around a pivot axis extending perpendicular to the tilt axes. When closed, the door leaf is mounted in an opening in the gate leaf and the door leaf extends essentially parallel to the plane of the gate leaf. A stabilizing arrangement opposes the deformation of the gate leaf and a threshold element which rests on the floor of the opening when the gate leaf is in the closed position. The height of the threshold element is essentially less than 20 mm, preferably less than 10 mm.

Abstract: Proposed is a structural component for the assembly of a sectional door, which is to be movable along predetermined guide rails between a closed and an open position. Included are an outer surface which lies remote from an inner space, which space is to be isolated upon closing the door, and an inner surface oppositely located from the outer surface. The component possesses lateral edges running approximately parallel to the guide rails. Overlapping an exposed lateral edge is protective sheathing forming a thereto affixed cap, running at least somewhat parallel to the lateral edges of the panels. As an optional choice, a protective edge sheathing may also be placed on the outside to aid in the incorporation of the invented structural component as described above.

Abstract: Disclosed is a door comprising a leaf (10) which is closable between an open position and an closed position, a guide rail arrangement directing the movement of the door leaf, a fastening arrangement fixing a rail element (20) of the guide rail arrangement to a wall by means of a plurality of fastening elements (30), each of which can be fixed to the wall as well as to the rail element (20), said wall having an opening which can be closed with the aid of the door leaf, and a pulling means which can be fixed to the door leaf (10) as well as to a drive unit and/or a weight-balancing device. The inventive door is characterized by the fact that at least one protective element (40) is assigned to the guide rail arrangement. Said protective element (40) can be fixed to the rail element (20) and/or at least one of the fastening elements (30) and is used for bridging an intermediate space between the rail element and the wall.

Abstract: An arrangement for monitoring a condition of a counterbalance torsion spring in an overhead door or gate and preventing the door or gate from accidentally slamming shut or dropping too rapidly when the spring fails. The arrangement includes a drum mounted on a shaft which transmits the torque of the spring to the drum. During normal operation a sensor and release assembly maintains a catcher in a inactive position and when the spring fails, the sensor and release assembly allows the catcher to move to an active position and engage a grabber disposed on an inside surface of the drum to block rotation of the drum and therefore movement of the door or gate.

Abstract: A sectioial overhead door is disclosed with a door leaf comprising several consecutive hinging panels (10, 10', 10") which are guided in the known way by rollers (11) in horizontal tracks and in tracks (12, 12', 12") joined to them to form a bow and are provided with a balancing device (15) in the form of approximately horizontal helical tension springs. The latter are designed to be space-saving, in particular with low drop heights, underneath the horizontal track sections extending into the building, such that on each of the outer side regions (27) of the horizontal track sections (12, 14) facing away from one another one or more helical tension spring units (16) are arranged approximately parallel to one another and one below the other. At least some of the helical tension spring units (16) consist of at least two coaxial helical springs (17, 18), the turns of which are mutually opposing and intersecting.

Abstract: Gate-panel element for a gate panel preferably made out of a number of such elements, a ceiling-component gate panel for example, with a space between outer layers, especially made of sheet metal, that enclose each other, and with a core, made of plastic, especially expanded plastic, that completely occupies the space. The element, in order to save weight, has a layer of plastic fibers against each surface of the outer layers that faces the core.

Abstract: An overhead door having a number of panels secured together by hinges, in which the insertion of a finger into a gap between the consecutive panels is prevented. Facing edges of ajdacent panels have areas that curve around an axis of the hinges to eliminate the occurrence of a gap as wide as a finger at any angle between the panels. Shoulder areas engage each other when the door is in the closed state, and they are located in the vicinity of the interior surface of the door and outside the curved edge areas that extend from the outer surface of the door. To facilitate manufacture of panels that will ensure that the door is tight, well supported, and precisely positioned when in the closed state, there is a section in the area of the gap between the facing edges of adjacent panels as viewed from the outer surface and toward the interior surface of the door. The gap distance is interrupted and the panels rest one on top of another when the door is in the closed state.

Abstract: Articulated overhead gate consisting of a series of adjacent and interarticulated panels with their sides facing one another, characterized in that the side of each panel that is uppermost in gate-closed state and faces a preceding panel has a curved surface that is convex in vertical section and the side that is lowermost and faces a subsequent panel has a curved surface that is concave in vertical section, with the result that the mutually facing convex and concave curved surfaces in each pair of adjacent panels demarcate a space that is dictated by the hinge between the panels and accordingly has curved edges, and in that the facing sides shift in relation to each other as they articulate around their associated axis of articulation during the transition from the gate-closed state into the gate-open state in such a way that the space remains but decreases along the direction of articulation during at least part of the transition into the state of maximum articulation.

Abstract: Sectional overhead garage door for low lintel heights, with the door leaf members of which, except for the one that is uppermost in the closed position, being guided in guide rails having a vertical, an arcuate, and a horizontal section, and with rollers of the uppermost door leaf member being guided in two guide rails, extending with an approximately horizontal section above and in parallel to the approximately horizontal primary guide section provided on the same side, and each of these being connected to an intermediate guide member adapted to be lowered from the horizontal in the direction of the upper frame zone, so that the uppermost door leaf member, when the door leaf is transferred into the closed position, passes into the plane of the closed door leaf along a shorter path than the remaining door leaf members.

Abstract: A sectional overhead door which, in its longitudinal rims pointing in the direction of movement, is inwardly angled in a C-shape and stabilized at marginal zones, by reinforcing struts extending in the direction of movement of the door, with the reinforcing struts contacting the sheet-metal panel of the door leaf member extending in the plane of the door leaf member, and being in shape-mating connection in their two end zones at the front face C-shaped angled portions extending in parallel to the plane of the door leaf member.
