Description

The invention relates to a device for opening and / or closing an opening with a door leaf, in particular a garage door, which is connected to an energy storage device via a drive train element.

State of the art

In the context of the prior art, the WO 93/16262 A1 , the WO 2006/099844 A1 , the FR 2 668 534 A1 and the DE 20 2005 020 731 U1 each of which describes a device for opening and / or closing an opening with a gate wing, in particular garage doors, the gate wing being connected to an energy storage device via a drive train element.

Devices for opening and / or closing an opening with a gate wing, in particular as a garage door, are known in various forms and designs and are on the market. As a rule, they consist of a frame and a gate wing, with the upper area of the gate wing being laterally provided with rollers that are guided in horizontal rails. When opening, the gate wing is raised, with its upper area sliding backwards approximately parallel to the ceiling and finally the gate wing is approximately parallel to the ceiling of the room. In doing so, however, the lower part of the gate leaf swings outwards so that it is swiveled out of the clear width of the opening and in again in an approximately circular arc. In this case, no object or person may be directly in front of this opening.

For example, from the DE 10 2004 005 423 A1 an overhead door known, which is known for closing an opening in a frame by means of a door leaf which is connected to the frame via a fitting, a rod being articulated near a bottom edge of the door leaf and at the other end via a pivot point around which the rod rotates, extends out and is connected at its end via a connecting element and an energy storage device with a pivot point close to the ground. The connecting element is connected to the rod via a hinge bracket which, with a support, presses against an inclined surface on the rod.

In many cases, the opening and / or closing of the door leaf is supported by an energy storage device, such as a spring assembly or a weight. For example, in the DE 20 2005 020 731 U1 a gate device is shown in which part of the force to be applied for lifting the gate leaf from the first closed state into the second open state is supported by a weight. Here too, however, the gate swings far beyond the clear width of the opening to be closed.

task

The present invention is based on the object of creating a device of the above-mentioned type in which the gate leaf does not swing open beyond the clear width of the frame, which shows a space-saving mechanism and in which the operation of the gate leaf is made easier and, in particular, made safer is.

Solution of the task

To achieve the object, the drive traction element can be wound onto a drive drum which is seated on a shaft on which a drum is also provided, which is connected to the gate leaf via a traction element.

This arrangement has the advantage that the gate wing is guided in every position of use. When the gate leaf is opened, the drive pulling element is unwound from the drive drum, at the same time the pulling element is wound onto the drum. This process is reversed when the gate leaf is closed.

In a preferred embodiment, the drum on the shaft is to be assigned a counter drum which is connected to the gate leaf by a parallel pull element. The drum and counter drum as well as the tension element and parallel tension element have the same function. For this reason, it should prove advisable to arrange the drum and counter-drum as well as the tension element and parallel tension element on one side of the gate leaf.

In the present case, the wave is a torsion wave. In this context, torsion means the twisting of a component, which is caused by the effect of a torsional moment. The use of a torsion shaft in the present case has the advantage that the cable guide is synchronized and pendulum-free running is made possible. In addition, the torsion shaft serves to ensure the force between the drive drum and the counter drum. When the gate leaf closes, force is exerted on the torsion shaft, which is released again when it is opened. The torsion shaft used is also commercially available.

The tension elements used, be it drive tension element, tension element or parallel tension element, are preferably steel cables, optionally with different diameters. The diameter should not matter either be like the material used. In the context of the concept of the invention, the focus is rather on the task that these different pulling elements are faced with. As a result, the configurations can be completely different in the case of door leaves or drums of different sizes.

The energy store has the advantage that less force has to be applied to open the door leaf. When closing, this force counteracts sudden closing. The energy store transfers its power via the drive train element to the drive drum and from there via the shaft, the drum and the counter drum to the pull element and the parallel pull element. These then support the opening of the gate leaf.

Various forms of energy storage can be used. In this context, weights, springs or the like may be mentioned as examples and not conclusively. The shape and weight of this energy storage device are not limited. Rather, it is important in this context that they can solve the tasks assigned to them. In detail, this means that the energy storage device should serve to facilitate the process of opening the door leaf.

This arrangement has several advantages. First of all, it should be emphasized that only a single energy store is now required, whereas commercially available garage doors often have an energy store, in particular spring assemblies, on both sides of their door leaves. This has the advantage that the device only needs the necessary space for an energy storage device on one side of the garage door and that this additional space can be used for a wider door on the other side. This also increases the clearance, for example in the garage. It is technically easily possible to attach the energy storage device on one side and on the other side of the gate leaf.

Another advantage can be seen in the fact that the saving of the second energy store saves components, the construction is simpler and parts that are less dependent on wear are used. Any simplification and saving of such parts also brings an additional gain in safety.

The shaft with the drive drum, drum and counter drum should preferably be arranged at the height of two upper, horizontal running rails for guiding the gate leaf and behind them, for example, on a ceiling. In this case, the tension element and / or parallel tension element are first guided by the drum and the counter-drum approximately parallel to the horizontal running rails and then deflected downwards to the lower area of the gate leaf by at least one first deflection roller, preferably a first and a second deflection roller. There they are then connected to a slack rope switch.

In the lower area of the gate wing there is also a guide roller, preferably a guide roller in each case on the side of a side frame or mounting bracket for the gate wing. This guide roller runs in a running rail which is inclined upwards in the direction of the first deflection roller for the pulling element or the parallel pulling element. This ensures that the lower area of the gate wing cannot swing out of the clear width of the opening frame when opening and closing. When used as a garage door, the invention represents a non-swinging up-and-over door. Non-swinging up-and-over doors have the advantage that they require little space, e.g. for underground garages which are also to be closed or opened by such a door. This is important because maneuvering is regularly difficult in such parking lots due to the limited space available. With swinging up-and-over doors, this narrow space would then also be taken up by the swinging door.

Wall strips are preferably provided on the side of the opening as the substrate for the running rails just mentioned. These are preferably made of sheet metal.

The material and the shape are not important. The idea of the invention is the focus of the protection request. It is then important that the material of the wall strip has sufficient rigidity and that it offers sufficient space for various other elements attached to it.

Another variant to relieve the tension elements shortly before the door is in the open position and thus to facilitate the pushing process from the open door leaf to the closed position, is a damping element which intercepts the energy storage mechanism shortly before the door is in the open position. Thus, the force that acts on the tension element is reduced.

A device for lifting the pulling element or the parallel pulling element on the drum or the counter drum is provided for further help, especially when closing the gate leaf. This device mainly has a ramp on which the tension element runs in the last stage of its winding onto the drum or counter drum, so that the tension element or the parallel pull element is lifted from the drum or counter drum. This corresponds to an eccentric increase in the drum diameter and thus a reduction in the force of the tension elements is achieved. So that the tension element or Parallel pull element does not slip off the ramp, it is provided with a shaft.

The device for lifting the tension elements is preferably made of plastic. However, other materials such as metal, ceramic or the like are. also encompassed by the inventive concept. Which materials are used in detail is not important.

It is also important in this context that the device on the drum can be adjusted. This means in detail that it can be moved back and forth on the circumference of the drum in question, but also that it can be fixed in any way. For this it is possible that the device is wrapped around by a clamp or the like and thus fixed to the relevant drum. Another conceivable procedure is to use a connecting or fastening element, for example a screw, which penetrates the device for lifting and is assigned to a designated opening in the drum. The only thing that matters here is that the device for lifting can be adjusted and fixed in any way.

The energy storage device should preferably be connected to the drive drum via the drive train element according to the pulley principle. This results in a suitable transmission of tension to the drive drum.

In addition to the advantages mentioned above, the device according to the invention offers an increase in safety, since two tension elements are used here. The principle of the double rope system is that in the event of one rope break, the other rope takes over the task on its own until, for example, the rope break is detected. In this context, however, it can often be observed that if a rope is corroded and locked to such an extent that it breaks, the other securing rope is also locked and then cannot additionally carry the weight of the other rope. The present invention solves this problem by providing two slack rope switches, one for the pulling element and one for the parallel pulling element. The slack rope switch is a commercially available slack rope switch and signals an emergency stop to the motorized drive in the event of a rope break. The arm of the motorized drive then holds the gate leaf in the position it has just reached.

In addition to this electrical safety system, a mechanical safety device is also used, especially for the drive train element. This mechanical safety device presents itself as a cable break safety device. This cable break safety device has a boom which continuously controls the tension of the drive train element. If the tension is lost due to a cable break, the boom falls down, takes a locking hook with it, which engages in a corresponding grid on or in the shaft and thus locks the shaft. This will stop the weight falling in the event of a rope break. At the same time, the gate wing is also determined so that neither the drum nor the counter drum on the shaft can turn. This prevents the gate wing from falling.

The motor drive shown here is only a preferred embodiment, which can be dispensed with at any time. The concept of the invention also includes the manual actuation of the gate leaf using body weight and muscle strength. Any other application of force should also be encompassed by the concept of the invention.

The device should not only be used as a garage door. Rather, it is intended that any gate wing that is intended to close an opening can be equipped with such a device.

The 1 to 3 first show the process of opening a closed gate leaf 1 . The gate wing is in the closed position 1 usually almost at right angles to completely right angles to a ceiling D. . An energy store is in this position 2 curious; excited. In the example shown, this means that the energy storage device shown as a weight in the present drawings 2 in the upper area near the ceiling D. is located and due to gravity a train on a drive train element 33 exercises.

The gate wing 1 is a motor drive 27 assigned, which is guided by a chain and an arm in a rail 29 the gate wing on this chain 1 opens and closes, with the one hand being the arm 29 with an upper marginal edge 34 of the gate leaf 1 and with the other end in the rail 28 connected to the chain. The motor drive 27 pushes or pulls the arm over the chain 29 in the rail 28 . In the in 1 The arm is in the position shown 29 far left.

The gate wing 1 a load distribution unit is assigned. This has a torsion shaft 3 in the closed position of the gate leaf 1 according to 1 is excited. This torsion wave 3 has commercially available springs and ball bearings at each end, which are not shown in detail in the figures.

On the torsion shaft 3 sit on different drums. In detail, it is a drum 6th , a drive drum 4th and a counter drum 5 . First of all, the drums are to be differentiated according to whether they are on the side of the energy storage device 2 (Drum 6th and drive drum 4th ) or on the opposite side (counter drum 5 ). Thereby meet drum 6th and counter drum 5 the same task. Both are about tension members 35 and 36 with the gate wing 1 connected. The drive drum 4th on the other hand is about the drive train element 33 with the lift mechanism 2 connected.

To simplify the description, the following only refers to the course of the tension element 35 received. The course of the parallel pull element 36 is designed the same on the opposite side. The tension element 35 is in the closed position of the gate leaf ( 1 ) unrolled from the drum 6th which special circumferential grooves 37 (please refer 4th ) having. The pulling element extends from the lower circumference of the drum 6th towards a second pulley 8th (please refer 7th ). It goes under the second pulley 8th and continues to the upper circumference of a first pulley 9 . The first pulley 9 and the second pulley 8th are at a console 10 arranged. The console 10 is located between a horizontal running rail 11 and a wall strip 7th . The one from the wall strip 7th concealed further course of the tension element 35 is in 7th shown in dashed lines, as well as the first pulley 9 and the hidden area of the console 10 .

From the first pulley 9 the tension element runs 35 down in the direction of a mounting bracket 13th which is good in 8th is recognizable. On this mounting bracket 13th there is an impeller 12th and a slack rope switch 14th . This slack rope switch 14th is used in the event of a break in the tension element 35 the drive 27 to put still. For this purpose there are slack rope switches 14th two contacts, which when the pull of the pulling element slackens 35 getting closed.

The mounting bracket 13th itself is in turn on a side frame 38 of the gate leaf 1 . With the gate leaf closed 1 , as in 1 shown, is the mounting bracket 13th near the bottom area. The tension element 35 partially revolves around an impeller 12th and then leads further up to the slack rope switch 14th . There is the end of the tension element 35 over a loop 39 with a hook 40 at the slack rope switch 14th connected.

On the mounting bracket 13th there is also a leadership role 30th , which in a running rail 15th to be led. This leadership role 30th works with a running rail 15th together, which are on the wall strip 7th and from the lower area across the wall strip 7th towards the console 10 runs.

This track 15th serves in conjunction with the leadership role 30th to do this, the gate wing 1 not to let it fade away.

On the drum 6th and the counter drum 5 is a facility 19th for lifting the tension element 35 or the parallel pull element 36 shown (see 4th and 5 ). It has an approach ramp 20th on. Into the ramp 20th is a groove 21 molded, which is parallel to the tension element 35 or the parallel pull element 36 runs. The establishment 19th is adjustable on the drum 6th or the counter drum 5 arranged and has for this purpose an arc of a ring 22nd on. This ring arch 22nd serves the facility 19th on the drum 6th or the counter drum 5 to lead and therefore has arched ribs 32 which are in the circumferential grooves 37 the drums slide. The facility can then be in a desired location 19th by means of, for example, a mounting clamp on the drum 6th or the counter drum 5 be determined.

The drive drum 4th is about the drive train element 33 with the lift mechanism 2 connected. The course of the drive train element 33 is in the 4th and 7th shown. The drive train element 33 runs first from the upper circumference of the drive drum 4th starting approximately parallel to horizontal track 11 . Then it runs around the upper circumference of another first pulley 16 and then turns down to another second pulley 17th diverted. The other second pulley 17th is firmly attached to the lift mechanism 2 connected. After the drive train element 33 now around the lower circumference of the further second pulley 17th has run, it is directed upwards. There it is then in a tab 18th hooked. The first pulley 16 and the tab 18th are located on another mounting bracket 41 on the wall strip 7th . 7th shows the position of the lift mechanism 2 with the gate leaf closed 1 . The other pulleys 16 , 17th and the tail 18th guide the drive train element 33 according to the pulley principle.

The drive train element 33 is a cable break safety device 23 assigned. It is also located on the torsion shaft 3 between drive pulley 4th and drum 6th and is with a boom 24 provided which with a finger 31 on the drive train element 33 rests. In addition, the cable break safety device has 23 about a lock 25th which in the event of a rope break in a grid 26th snaps and the gate wing 1 sets by it the torsion shaft 3 locks and prevents further rotation.

10 shows a damping element 42 , which from one mainstay 43 , a spring 44 , a lock plate 45 and a bolt 46 consists. The preferred embodiment is a compression spring system. It is irrelevant here whether the supporting leg 43 who have favourited the lock plate 45 and the bolt 46 consist of one piece, whether they are welded together or otherwise connected to one another. The bolt 46 penetrates the pen 44 . The damping element 42 the tension elements are used for this purpose shortly before the gate leaf is in the open position 1 to relieve by increasing the energy store 2 intercepts shortly before the open position. In addition, it is located with the supporting leg 43 on the floor and with the other end either on the lift mechanism 2 subsequently or at least in the position under the energy storage mechanism 2 to be able to intercept him. A connection between the energy storage mechanism is not necessary, but should not be ruled out either.

• Zieht der motorische Antrieb 27 an der Kette und damit auch an dem Arm 29 Torflügel 1 geöffnet. Dabei wird der erste Teil des Öffnens nicht nur dadurch unterstützt, dass der Kraftspeicher 2 über das Antriebszugelement 33, die Antriebstrommel 4, die Torsionswelle 3 die Trommel 6 und die Gegentrommel 5 einen Zug auf Zugelement 35 und Parallelzugelement 36 ausüben, sondern zusätzlich gibt die Torsionswelle 3 die beim vorherigen Schließen des Torflügels 1 in sie eingebrachte Kraft frei und erleichtert ein Öffnen. Beim Drehen von Trommel 6 und Gegentrommel 5 werden Zugelement 35 und Parallelzugelement 36 aufgewickelt.

The mode of operation of the present invention is as follows:

• The motorized drive pulls 27 on the chain and thus also on the arm 29 Gate wing 1 open. The first part of opening is not only supported by the fact that the energy store 2 via the drive train element 33 , the drive drum 4th , the torsion shaft 3 the drum 6th and the counter drum 5 a pull on pulling element 35 and parallel pull element 36 exercise, but also gives the torsional wave 3 those when the gate leaf was closed beforehand 1 force introduced into it and facilitates opening. When rotating drum 6th and counter drum 5 become a tension element 35 and parallel pull element 36 wound up.

Halfway through the opening process according to 2 the lift mechanism is located 2 now in a middle position between the ceiling D. and soil. The arm 29 is located approximately in the middle of the rail 28 .

If the opening process is continued in this way, the gate wing is reached 1 in the 3 position shown and is approximately parallel to the ceiling D. . The torsion shaft 3 will be in this position through the establishment 19th relieved. The energy store is in this position 2 in the lower area of the wall strip 7th close to the ground. The drive train element is from the drive pulley 4th settled. In contrast to this is the tension element 35 on the drum 6th and the parallel pull element 36 on the counter drum 5 wound up. The torsion shaft 3 is completely relaxed in this position. The motor drive 27 has the arm 29 in the rail 28 , as in 3 shown, pulled as far as possible to the right.

When the gate leaf is closed, the procedures described are reversed and applied to the torsion shaft 3 , as well as energy storage 2 force is exerted. This means in the case of the energy store 2 that this is by means of the pulley principle over the rollers 16 , 17th and in interaction with the drive train element 33 and drive drum 4th again in the, in 1 Position shown, in the upper area of the wall strip 7th is brought. In addition, the tension element roll 35 and parallel pull element 36 of drum 6th and counter drum 4th from. The gate wing 1 brought into a vertical position in a mainly downward motion.

Shortly after the gate leaf 1 leaves its open position, the traction elements run 35 and parallel pull element 36 from the ramp 20th the facility 19th and thus develop the normal force again, which is required for a balanced closing process.

Just before the gate wing 1 adopts its closed position, tension elements run 35 and parallel pull element 36 on the ramp 20th the facility 19th on and so from the drum 6th or the counter drum 5 lifted. This creates an additional pull on the lower area of the gate leaf 1 exerted a safe closing of the gate leaf 1 guaranteed.

During this opening and closing process, the gate wing does not swing outwards. This prevents the running rail 15th along which the guide roller 30th and thus the lower part of the gate wing that normally swings out 1 to be led.
