Definitions

  • the invention relates to a gate, in particular a sectional overhead door, according to the preamble of claim 1, which requires only a small lintel height and, for this purpose, is largely horizontal and flat in the open state and requires only a small second force to keep it open.
  • the door leaf can be rigid or flexible or can have several sections, slats or panels which are connected to one another in an articulated manner.
  • German patent specification 840 364 shows a lifting or overhead sectional door, the door leaf of which is connected to a vertically extending tension spring by means of a block and tackle to compensate for the weight of the door. Furthermore, an additional weight compensation device, which consists of a weight and / or a compression spring, is provided, which serves for weight compensation in the lower and in particular the upper end position of the door leaf. No information has been given on the spring constants of the tension and compression springs.
  • the weight balancing device is intended for gates that cannot be pushed back into a horizontal and flat open position, so that a relatively high second force for balancing the weight must act on the gate even in the open position.
  • the device shown is not suitable for gates on which only a slight force is to act over a relatively long sliding path until the end position is reached, as is the case with the gate according to the invention.
  • German Offenlegungsschrift 26 53 980 discloses a spring balancing device in which several springs are functionally connected in series, the springs partially overlapping.
  • a shaft provided with torsion springs as a pulling device for sectional doors, which is arranged horizontally above the door frame.
  • the shaft has a rope drum on both ends, on which a pull rope is rolled up and down while the door leaf is moving.
  • a pulling device suitable for a tilting gate or overhead sectional door should meet several requirements.
  • the first force directed against its weight should be sufficiently high for an easy opening of the door, but not so large that the door leaf opens by itself.
  • the second force acting on it should keep the door leaf safely open, for example even in the event of a sudden gust of wind, but it should be small enough to enable the door to be closed conveniently by hand.
  • the pulling device should exert a force on it which is suitable for facilitating the handling of the door.
  • the object of the invention is to provide a pulling device for facilitating the handling of a gate mentioned at the outset which fulfills the above-mentioned requirements.
  • the pulling device is designed according to the features of claim 1 at a gate of the type mentioned.
  • the tensile force initially increases proportionally to the elongation of the two tension elements with a low proportionality factor, which is essentially determined by the spring characteristic of the first, much weaker tension element. Since the length of the first tension element is limited to a maximum value which the first tension element assumes in an intermediate position of the door leaf, the tensile force increases with a greater proportionality factor, which is only determined by the spring constant of the second tension element, according to its elongation when the door leaf is closed further at. A relatively closed force thus acts on a completely closed door leaf, which results from the sum of the forces of the maximally stretched first tension element and the second tension element.
  • the traction device according to the invention can be adapted particularly precisely to the requirements for comfortable handling of the gate by suitable selection of the traction elements, the maximum length of the first traction element and the pretension.
  • the pulling device is robust, reliable and relatively inexpensive to manufacture, store and assemble.
  • the first and / or the second traction element of the traction device according to the invention has a plurality of elastically stretchable traction means acting in parallel, a break in one of these traction means is partially compensated for by the others and does not lead to the door leaf suddenly falling off.
  • Each individual traction device only needs to have a low spring strength, so that it is easy to attach and replace by hand.
  • the traction means can be elastic bands or ropes, but it is preferably springs, in particular coil springs made of metal.
  • the first tension element has a smaller spring constant than the second tension element.
  • the invention is The gate is completely flat and horizontal in the open position so that it would remain in this position without any external force.
  • the first pulling elements in this case only have the task of preventing the second tensioning elements, which are hardly under tension, from sagging too much, touching one another during the movement and producing unpleasant noises.
  • the device for limiting the stretching of the first tension element prevents excessive stretching of this tension element, which could exceed its elastic limit. If the traction elements consist of several traction means acting in parallel, the different traction effects can also be determined by a different number of traction means. The number of different construction and spare parts is reduced if all traction devices are of a uniform type.
  • the device for limiting the expansion of the first tension element can be formed, for example, by a stable rope of a predetermined length, which is arranged inside or laterally of this tension element and connected to the ends thereof.
  • this device preferably consists of two adjustable stops for an intermediate piece which connects the first and the second tension element to one another. This intermediate piece is used to hang the ends of the traction means.
  • the pulling force is preferably transmitted from the pulling elements to the door leaf via at least one cable which is connected to the second pulling element and the door leaf. Since such a rope becomes fragile due to aging and can easily be damaged, it is advantageous to increase safety and durability if the traction device for transmitting the tensile force has at least two ropes running next to one another and connected to the door leaf, in particular two plastic ropes, two steel ropes or a plastic and a steel rope. The latter combination combines the cut resistance a metal rope with the long life and flexibility of a plastic rope.
  • the pulling device has a block and tackle for increasing the pulling length provided by it.
  • This block and tackle can be formed in that the pulling device acts on a roller of the block and tackle and the tensile force is transmitted from one end of a rope placed around this roller and fixed at the other end to the door leaf.
  • the pulling device can be assembled and repaired particularly easily if it has a device for pretensioning the first and / or the second pulling element in the open position of the door leaf. Since only a slight pull, which can be achieved with two fingers, approximately 10 N to 15 N, is required in this position, the pretensioning can be carried out easily and without danger by hand without tools.
  • a pulling device designed in this way is particularly advantageous in comparison to the pulling devices arranged transversely above the door frame, because tensioning the torsion spring here is uncomfortable, time-consuming and even dangerous.
  • the pulley block also serves to amplify the force acting on the first and / or the second tension element during pretensioning.
  • the pulling device preferably has a guide rail for receiving at least the first and the second pulling element.
  • the guide rail can be a tube with a round or rectangular cross section. However, it is preferred to be open along its length because of the easier accessibility for repairs. It then has a C-shaped or U-shaped cross section.
  • the tension elements are preferably arranged in the guide rail in such a way that they are not in direct contact with the inner wall of the guide rail when the tensioning device is tensioned and relaxed. This reduces wear and prevents noise when opening and closing the door.
  • the intermediate piece connecting the tension elements preferably runs in the guide rail.
  • the intermediate piece can slide in the guide rail or be provided with rollers.
  • the tension elements held on the intermediate piece are guided through this and held in the interior of the guide rail without coming into contact with the inner wall.
  • an end piece connected to the second tension element and running in the guide rail is provided, which has a role of the pulley block.
  • the door preferably has two rails for the door leaf on each side, each with an essentially horizontal section.
  • the guide rail designed as a spring box with a C-shaped cross-section connects and reinforces the two horizontal sections of the running rails, so that the running rails serve as carriers for the tandem spring balancing.
  • the running rails and the pulling device with guide rail, pulling elements and other parts form a compact transportable and installable unit.
  • the pulling device takes up little space and can therefore also be installed in small and narrow buildings, especially garages. It is preferably arranged at a height above a motor vehicle parked in the garage, so that it does not hinder it. This height can essentially correspond to the height of a frame of the door.
  • the pulling device is preferably aligned normal to the plane of the closed door leaf. It does not need to rest directly on the door frame, but can be arranged at a certain distance from it.
  • the pulling device is equipped with a guide rail, and the guide rail is arranged on the horizontal region of the running rail in a manner normal to the plane of the closed door leaf at a distance from the door frame and approximately at the height of an upper horizontal section of the door frame.
  • the door frame can be approximately as wide as the building without having to provide space for the pulling device laterally next to the door frame. This is particularly advantageous in modern precast concrete garages.
  • no high lintel is required because there is no torsion spring shaft arranged transversely above the door leaf close to the door frame. A lintel height of 80 mm or 120 mm is sufficient.
  • the first and the second tension element or, if present, the guide rail is preferably arranged laterally on the substantially horizontal section of the at least one running rail close to a lower edge of this section. With this arrangement it is possible to tension the tension elements in a normal garage standing on the floor without tools and without restricting space.
  • the arrangement of the guide rail on the side of the running rail serves for safety during use, because if one of the tension elements breaks, the parts of the broken spring are deflected to the side and cannot fly freely through the interior of the garage.
  • the guide rail, the at least one running rail and other components preferably form a preassembled component and a transport unit.
  • a overhead sectional door for a garage has two superimposed runners on each side, the upper of which in a region in the upper third of the door frame, preferably almost at the upper edge of the door frame, at right angles or with a maximum of 30 ° (preferably 10 °) butting the upward-facing angle against the door frame.
  • either the rollers assigned to the upper track must be set higher, or the drive must be arranged so that it can move the sectional door vertically upwards by the aforementioned 50 mm at the start of the opening process only then move on horizontally.
  • an upper running track starting from an upper edge of a door frame, is initially guided straight or upwards in a curve at an angle of approximately 10 ° with respect to the horizontal and then merges into a section pointing horizontally into the garage.
  • a further, lower running rail is provided, which has an approximately vertical section arranged near a lower region of the door frame, then an arcuate curved or straight section inclined upwards and finally a horizontal section, which is below the horizontal section of the corresponding upper running rail is arranged.
  • FIG. 1 shows a garage which has a door according to the invention with a door leaf 10, a frame 20, a lower running rail 22 and an upper running rail 24.
  • the door leaf consists of a lower section 12 and an upper section 14 which are articulated to one another.
  • the lower section 12 is guided at a lower and an upper area with rollers on the lower track 22.
  • the upper section 14 is guided on a lower region on the lower running rail 22 and on an upper region on the upper running rail 24.
  • the lower track 22 has a vertical one connected to the frame 20 and extending from a floor of the garage Section up, then an oblique or curved middle section and finally a horizontal section that runs perpendicular to the plane of the closed door leaf 10.
  • the upper running rail 24 is connected to an upper edge of the frame 20 and from there is initially guided slightly obliquely upwards and then horizontally into the garage.
  • the horizontal sections of the lower running rail 22 and the upper running rail 24 are arranged parallel and closely adjacent to one another.
  • a locking device arranged at the upper edge of the upper section 14 prevents, by engaging the frame 20, that the upper section 14 of a closed door leaf 10, which is guided on the area of the upper running rail 24 which rises only slightly upwards, for example by a gust of wind is pressed inside.
  • a guide rail 32 with a C-shaped cross section, which is part of a pulling device 30, is attached to the horizontal sections of the running rails 22 and 24.
  • the traction device 30 also has a first traction element 40 and a second traction element 50.
  • the first traction element 40 is formed by traction means 42, 44, and the second traction element 50 by traction means 52, 54, 56.
  • the traction means 42, 44, 52, 54, 56 are each designed as a coil spring, the first traction element 40 being one has a substantially lower spring constant than the second tension element 50, for example only 5% of the spring constant of the second tension element 50.
  • a first end of each of the coil springs of the first tension element 40 is hooked into an end piece 34 which is fixedly connected to the guide rail 32, and a second end in each case into an intermediate piece 60 which can be displaced in the guide rail 32.
  • the guide rail 32 has a stop 62 consisting of two lugs , which serves to limit the maximum displacement of the intermediate piece 60 to the left in FIG. 1.
  • a first end of the coil springs of the second tension element is also suspended in the intermediate piece 60.
  • a second end of each of these coil springs is in the guide rail 32 sliding end piece 80 hooked, which also has a roller 82 acting as part of a pulley block.
  • a tension member 70 which is formed from two ropes guided next to one another, namely a steel and a plastic rope, is fastened to the lower edge of the lower section 12 and is attached to the guide rail 32 via a guide 26 connected to the lower guide rail 22 and one small roll 86 led to roll 82.
  • the tension member 70 wraps around the roller 82 at 180 °, is then guided along the guide rail 32 via a deflection device 84, which likewise wraps around it at 180 °, and is finally fastened to a suspension bracket 72.
  • the hook-in tab 72 has holes in the form of elongated holes, which can be hooked into a mushroom-shaped bolt 36 of the guide rail 32.
  • the desired tensile force can also be exerted in the event of material fatigue of the tension elements 40, 50 or with increased friction of the door leaf 10 be adjusted in the rails 22, 24. If a spring breaks, the pretension can be increased without tools so that the door continues to function until it is repaired.
  • the second tension element 50 When the door is opened, that is to say when the door leaf 10 is transferred from the closed to the open position, the second tension element 50 first relaxes until it develops only about 5% of its tensile force when the door is closed. Only then does the tensile force of the first tensile element 40, which is still maximally stretched, prevail, which now pulls the intermediate piece 60 away from the stop 62 and thus prevents the gate from closing.
