Definitions

• the present invention relates to a sectional door with drive for door openings with a particularly low lintel height between the upper edge of the door opening and an adjacent ceiling area.
• Sectional gates or sectional sectional gates close open door openings in buildings, garages and the like.
• the sectional doors generally comprise a door leaf made up of a plurality of closure elements which are successively articulated to one another in the direction of movement and which are guided in guide rails by means of roller guides.
• the running rails each have a vertical section in which the rollers of the closure elements are in the closed position, an adjoining arch section and subsequently a horizontal section in which the rollers for the open position are moved.
• the vertical sections are arranged on both sides of the door opening and relative to the door opening behind the locking elements, so that the rollers have to be attached to the rear of the locking elements.
• the horizontal sections are fastened under a ceiling or the like of the building to be locked.
• these sectional doors also have a weight compensation device which largely compensates for the weight of the closure elements in the closed position and is said to facilitate opening of the door.
• a weight compensation device which largely compensates for the weight of the closure elements in the closed position and is said to facilitate opening of the door.
• the weight compensation device has a hollow shaft that is pretensioned with torsion springs and that comprises a winding drum on both sides for winding a steel cable attached to the lower closure element.
• the hollow shaft with the two drums is arranged above the end edge of the clear door opening, so that the building must have a large lintel height above the door opening.
• it is one Weight balancing system in view of its various individual parts is comparatively complex and its assembly, in particular the pretensioning of the torsion springs, is complicated and therefore expensive.
• Such a sectional door is also to be movable via an electric drive
• a drive usually has a slide which can be moved in a running rail which is oriented in the direction of movement of the door and is arranged horizontally above the open position.
• the carriage is driven by an electric motor which is arranged behind the horizontal sections with respect to the gate opening.
• the slide is connected in an articulated manner to the upper closure element of the door leaf via a push rod, so that the door leaf can be moved from the closed position to the open position on its running rail when the slide is moved.
• a motor-driven sectional door of this type therefore has an additional running track which must be arranged above the open position of the door leaf.
• the drive device comprises a motor-driven drum, which is arranged above the clear door opening along the lintel.
• Tension elements such as steel cables or belts, are rolled up on both sides of the drum and engage the lower closure element. When the pulling elements are rolled onto the drum, the lower closing element is raised, the closing elements above moving along the running rails and the gate being opened.
• the object of the present invention is therefore to propose a particularly simple sectional door with a drive device which is suitable for door openings with a particularly low lintel height.
• the sectional door according to the invention comprises a plurality of closure elements which can be pivoted relative to one another about horizontal axes and which are guided in laterally arranged rollers in running rails, the running rails comprising a vertical section, a horizontal section and a vertical section with the horizontal section have connecting arc section.
• the drive device has a drivable drum with traction means, the traction means on the one hand engaging one of the closure elements and on the other hand being able to be wound onto the drum.
• the drum is arranged transversely with respect to the gate opening behind the horizontal regions of the running rails and the traction means are guided at least partially, indirectly or directly, on the running rails.
• the drive drum can therefore no longer be mounted above the door opening behind a lintel, so that the required installation height of the door is greatly reduced compared to the known gates. Since the tension elements are also guided on the running rails, it is also not necessary to install deflection rollers in the area behind the door opening. It follows from this that no functional elements of the door above the door opening are required which extend over the plane defined by the horizontal regions of the running rails. The Horizontal areas of the running rails can thus be mounted directly below the ceiling of the building to be locked, so that a maximum passage height is achieved below the gate.
• the expression horizontal region of the running rail represents a section of the running rail that is angled with respect to the vertical section.
• the present invention is also applicable, for example, to a sectional sectional door with a roof sequence in which the angled section of the running rail runs along a sloping roof.
• the proposed sectional door does not need a weight compensation device, since the entire effective weight of the closure elements is absorbed by the drive device.
• the problems occurring with the known gates, such as spring break or drum breakage of the weight compensation device, cannot therefore occur with the proposed gate.
• both the torsion springs and the steel cables of the weight compensation device as well as various components of the drive motor for locking the gate are under tension in the closed state. Since the gates are in closed condition for the vast majority of their service life during normal use, this means that these functional elements are constantly under tension, which leads to increased material fatigue and the associated defects such as fatigue fractures.
• the traction means and the drive unit are under tension only during opening and when the door is open; in the closed state, no functional element is live. The material fatigue described above is therefore not an issue with the proposed sectional door.
• the drive drum can be mounted directly on the ceiling behind the horizontal areas.
• the drive drum is mounted directly on the horizontal areas of the running rails.
• the running rails can form a preassembled unit with the drive drum, which considerably simplifies the assembly work of the gate on site.
• a person skilled in the art will find that the arrangement of the drive drum directly behind the running rails has an advantageous effect on the space requirement of the door construction in the running direction of the door.
• the traction means preferably engage a lower closure element, so that the weight of the closure elements is borne by the traction means and not by the pivot axes between the closure elements.
• the traction means have two belts, one of which engages on each side of the corresponding closure element and is guided on the corresponding running rail.
• belts can be rolled up in several turns lying one above the other.
• the lateral space requirement of the rolled-up traction means is therefore minimal and the length of the drum essentially only has to correspond to the distance between the two belts.
• the lateral expansion of the drum is minimal, so that the entire construction is characterized by a very small lateral space requirement. This is particularly important if the space to be closed has a small lateral extent, e.g. such as. for garage boxes.
• the belts preferably each run above the corresponding running rail. In this way, a very simple and inexpensive guiding of the belts is made possible, which does not require additional components and without additional installation space. It should be noted that with such a configuration, the low friction of the belts on the running rails has a particularly advantageous effect on the wear of the running rails.
• the traction means act on the corresponding closure element by means of a roller-guided bracket, the roller-guided bracket being articulated on the closure element at a first end, the traction means engaging on a second end of the bracket and between the first and the second end the bracket a roller is arranged, which is guided on the running rail.
• the bracket can, for example, be mounted on the closure element by means of an axis of rotation and a fitting.
• the fitting advantageously also serves to mount the roller assigned to the closure element. Since the middle of the bracket is guided with its own roller on the running rail, the attachment point of the belt runs with a corresponding design of the bracket on a path whose radius is greater than that of the curved section of the running rail.
• Such a bracket thus enables improved traction of the traction means in the area of the curved sections of the running rails.
• the tension on the traction means decreases, so that the bracket can be pivoted about its articulation point on the closure element.
• This pivoting movement can advantageously be used to lock the door if the second end of the bracket also has a laterally extending locking tab which, when the door is closed, engages in an associated locking of the door frame when the bracket is pivoted. This can effectively prevent the gate from being pushed up. Is the gate by means of the When the drive is open, the traction means are first tensioned and the bracket is pivoted back into its starting position. The lock is automatically released and the gate can be opened.
• shackles with locking tabs can be mounted on several or all locking elements, with a corresponding locking device on the goal frame being assigned to each of the locking tabs when the door is closed.
• the additional stirrup can be a simplified version of the stirrup described above, since the additional stirrups do not serve to grip the tension belts and therefore do not have to have a guide roller or a load-bearing point of attack for the pulling means. Since no force is transmitted to the closure elements via the additional brackets, these brackets need not be articulated on a separate axis of rotation but can be articulated on the axis of rotation of the rollers of the respective closure element.
• the sectional door according to the invention additionally has at least one spring element against which the closing elements are moved in order to achieve an open position of the door.
• the spring element can comprise, for example, a spring-loaded plunger assigned to the horizontal region of the running rail, the spring-loaded plunger being arranged in the rear region of the horizontal region with respect to the gate opening and being guided in the opening direction of the gate.
• the spring element is preferably arranged on the horizontal region of the running rails in such a way that one of the closing elements of the gate runs against the spring element in the last part of its opening movement and prestresses it.
• the spring element should be designed such that when the tension in the traction means decreases, the spring element can move the closing elements in the closing direction of the door.
• the tension in the traction means decreases and the closing elements are removed from the spring element or elements Closing direction moves until the weight of the locking elements moved into the vertical sections of the running rails is sufficient to overcome the rolling resistance of the guide rollers and the door closes under the weight of its locking elements.
• the door construction can consequently be designed in such a way that, in the open position, all the closure elements are completely in a horizontal position without the drive device having to be designed for thrust. With this configuration, a maximum headroom below the opened gate is therefore guaranteed.
• the drive device of the sectional door can comprise, for example, an axis motor, the driven axis forming the drivable drum.
• the axis motor can be arranged laterally outside of the central region defined by the imaginary extension of the horizontal regions, the driven axis of the motor extending into this central region.
• the axle motor can be mounted in the central area, with the driven axis of the motor extending on both sides thereof.
• the drive device comprises a tubular motor which is arranged within the drum and, for example, engages a flange mounted on the running rail. This configuration is again characterized by the small lateral space requirement outside the running rails.
• the motor can be, for example, a direct current tubular drive, which can also be operated by means of a rechargeable battery in the event of a power failure. If necessary, a gear with a hand crank can additionally be provided, by means of which the sectional door can be operated in the event of a breakdown of the tubular motor.
• a sectional door preferably also has a fall protection device to prevent the closure elements from falling in the event of a technical defect, for example in the event of a belt or rope break.
• the sectional door of the present invention is of a very simple construction which is characterized by its particularly compact dimensions in terms of height, width and depth. Thanks to these properties, this sectional door is particularly suitable for installation in confined spaces, for example with very low lintel heights or in very tight spaces. Thanks to the compact dimensions, a maximum clearance opening can be achieved even in such conditions. It will be clear to the person skilled in the art that the present invention is not restricted to a specific type of door.
• sectional door according to the invention can be both a monorail system, ie a construction in which all the guide rollers of the closure elements are guided on both sides in a single running rail, and a two-rail system, ie a construction in which the upper guide roller of the upper closure element is guided in a separate running rail.
• the lateral running rails each have an upper rail for guiding an upper roller of an upper closure element and a lower rail for guiding the rollers of the other closure elements, at least in the region of the horizontal section.
• the upper rail is arranged laterally with respect to the lower rail and offset downwards with respect to an upper edge of the lower rail.
• the upper rails can theoretically be displaced downward with respect to the upper edge of the lower rail such that the axes of rotation of the rollers of the upper closure element run just above the upper edge of the lower rail.
• the height can theoretically be reduced by the difference between the radius of the upper roller and the radius of the axis of rotation of the upper roller.
• the upper rail and the lower rail are preferably connected to one another by means of a suitable profile, so that the two rails can be easily assembled.
• the profile can preferably additionally form a guide surface for the traction means. It should be noted that the uppermost rollers of the sectional door, i.e.
• the rollers of the upper closure element are advantageously designed as a tandem roller with two individual rollers arranged one behind the other in the running direction, the articulation point of the tandem roller being arranged on the upper closing element in the running direction of the tandem roller between the axes of rotation of the individual rollers and is offset upwards with respect to these axes of rotation.
• This arrangement of the point of attack locks the uppermost closure element after the gate has been closed, so that it cannot be tilted out of its closed position.
