Description

The invention is directed to a sectional door with a tank of a plurality of transverse, hingedly interconnected and by means of guide rollers along guideways movable up door sections, the guideways each having at least one vertical section and at least one horizontal section and an intermediate transition section arranged therebetween in which at least one reversible rocker is arranged, so that certain guide rollers can run in a first position of the respective rocker when opening the door along an arcuate track section from the vertical track section to the horizontal track section and when closing the door in the opposite direction, or that at a different position of the rocker certain guide rollers are directed to another track section, which extends at least partially purely vertical and one there rin rolling guide allows a pure vertical movement.

For some time swing-open leaves and door leaves on rails are known, but which are not feasible especially in tight spaces, for example, in several, juxtaposed or close to a street placed garages often for reasons of space. Therefore early tilting gates were developed, which tilt upwards and inwards and therefore take up little space outside; However, it may be problematic werder to incorporate such a tilt gate on individual garages, because it can be damaged in this parked vehicle with large tailgates or even vans or minibuses of the inwardly tilting gate. overhead doors 46 . 47 as they are in the 9 and 10 may be more favorable from this point of view, because the gate swings partially or even predominantly to the outside and is pushed into the garage only in the raised state; However, this again raises the problem that possibly the passing on a nearby road traffic is obstructed by the far swinging gate leaf.

Therefore, sectional doors have already been developed, which are now known in various embodiments. They are based largely on the same technical operating principle to close gate openings in buildings and garages: They consist of several transverse, along their horizontal edges hinged interconnected and upwards folding or sliding door sections along both sides with ball bearing guide rollers along be moved by guideways. These rollers lead the sectional door upwards. When the door height is reached - usually just below the ceiling - they are deflected by a bracket on each side by 90 ° in a horizontal direction and then run along a horizontal rail section in the interior of the room - the tank is deposited below the ceiling of a garage, the Gate is open.

Depending on the local space conditions, the guide rollers, for example, normal fittings 41 Guided as the sectional door 40 after the enclosed 6 with a fall requirement of 300 to 500 mm or as with the sectional door 42 according to the enclosed 7 and 8th about low fittings 43 , where a lintel height between 180 and 250 mm can be reached.

Due to the height of the radius in normal fitting, the dimension for the overhead door section increases by 60 mm. When using the low fitting 43 with a lintel height of 180 to 250 mm will in addition to the main rail 44 still a second track 45 needed, cf. 8th to cancel the self-locking in the lintel area by a running track inclination. It is precisely this that results in an increase in the required larger lintel height.

Since on the one hand such large lintel heights limit the clear headroom and on the other hand modern passenger vehicles are getting bigger and bigger - think off-road vehicles or SUVs - is already in the DE 10 2004 047 167 A1 have been proposed to provide two different guide paths in the transition region between a vertical portion of the guideways and a horizontal portion of the guideways, between which a reversal with a kind of switch can be made. As a result, for example, the guide rollers for the top and the bottom door section take a different route than the guide rollers of the other door sections. This makes it possible to achieve a complete opening on the one hand and a complete closing each with a further reduced fall height. The need to arrange two horizontal track sections on top of each other as in a low fitting, is eliminated. However, this arrangement obviously still has a need for development, because in the usual drive mode of a sectional door by coupling the drive to the top door section precise guidance of the bottom door section is problematic; In order to avoid jamming, complicated linkages are provided there for the complete pushing up of the lowermost door section, which are susceptible to interference.

From the described disadvantages of the prior art results in the invention initiating problem, a generic sectional door in such a way that even with a very low lintel height, the complete opening and closing of the door curtain can be achieved with simple means.

The solution to this problem is achieved in a generic sectional door in that acts on a region of the lowermost door section, which performs a pure vertical movement when opening and closing the tank, a device for driving and / or to support the opening and / or closing movement of the tank ,

Ideally, the lower edge of the lowest door section can always remain in the area of the closed door shell. This has several advantages: First, it can be used to minimize the length of the horizontal section of the guideway; On the other hand, in spite of the generally complicated trajectory of the door curtain, there is then a total of a door section with a comparatively simple geometry of movement, which is particularly suitable for coupling a drive.

It has proven to be advantageous that the drive and / or support device for the opening and / or closing movement of the tank engages at least one guide roller of the lowermost door section, in particular on an axis or storage thereof. At this guide roller can be ensured by a suitable course of the guideway over the entire height of the door opening a purely vertical movement.

The invention further provides that the drive and / or support device for the opening and / or closing movement of the tank has at least one loop, an eyelet or a hook, which (or) surrounds the axis of at least one guide roller of the lowermost door section is hooked. Although the axis of a guide roller is a moving part; On the other hand, however, this follows completely unadulterated the respective guideway and on the other hand - especially between the actual leadership and a storage for the same - od of a loop, eyelet. Like. Enveloped so that they can not slide down from this axis.

The invention can be further developed in that the loop, eye or hook is arranged on a traction means whose subsequent strand extends vertically. This vertical course follows the guideways for the tank. During its movement, the movement of the respective traction means strand is reduced to a pure longitudinal displacement.

By pulling on the traction means so the vertical lifting movement of the door can be specified exactly.

In the area of the lintel, the traction means can be guided over a deflection roller. As a result, it is possible to arrange the actual drive or a drive support device, to which the traction means is coupled in terms of effect, at a location remote from the fall, where it finds sufficient installation space.

The traction means can be coupled to a drive device and / or to an energy store. Here, a drive device is to be understood as an active energy supplying component such as a motor, in particular an electric motor. An energy storage, however, should be understood as a passive element to support a manual opening and / or closing movement, for example. This may be, for example, a spring that absorbs energy when moving in one direction and releases it again in an opposite movement. Thus, for example, during a closing movement, the weight of the door could be collected and used to tension a spring, which provides its energy when opening the door supportive available, so that the door armor can be easily moved despite its weight upwards. As a result, for example, a smooth gate operation would also be possible in places where no electrical or other energy is available.

Although all engine types would be conceivable as a drive device such as hydraulic motors; however, the use of an electric motor is recommended.

In the energy storage should be taken to ensure that this can absorb and release mechanical energy directly. The simplest, although by no means the only possibility for this is a spring accumulator, in particular in the form of a torsion spring which is fixed on one side and rotates when winding a coupling traction means on a drum with the other end and thereby twisted and stores energy that is permanently available and at a later time - for example, when the door is to be reopened - can be retrieved.

A further improvement of the invention in an arrangement, wherein in the region of the second guide track portion, in particular in a vertical portion thereof, means are provided to push the bottom door section from its uppermost raised position down and thereby closing the movement Panzers initiate and / or support. This is a useful supplement to the invention, since a traction means can not transmit compressive forces. In the event that no additional coupling between a drive or drive support unit and the door curtain is provided, thereby the door curtain can be moved automatically at the beginning of the closing process so far that then the weight of the lowest, already hanging door section (s) is sufficient to maintain the closing movement automatically, as long as the traction means is released.

Further advantages arise when the device for initiating and / or supporting the closing movement of the tank engages an area of the lowermost door section, which performs a pure vertical movement when opening and closing the tank. At a pure vertical movement, a device for initiating and / or supporting the closing movement of the tank can be adapted and coupled with little effort.

From a comparable point of view, the invention recommends coupling the device for initiating and / or supporting the closing movement of the tank on at least one guide roller of the lowermost door section, in particular on an axis or storage thereof, because as the guide roller itself so also performs their axis - apart from a rotational movement - a pure vertical movement.

By the means for initiating and / or supporting the closing movement of the tank has at least one movable part which engages over the axis of at least one guide roller of the lowermost door section and is lifted by the latter when opening the tank, can in the simplest way a vertical force between them Elements are exchanged. It is not necessary for these two interacting elements to be in constant contact with each other. It is enough that these find themselves as soon as the door armor approaches its opening position.

The axis of at least one guide roller of the lowermost door section cross-part should be movably guided or stored in the vertical direction, so that it performs a precise voherd defined movement.

If the axis of at least one guide roller of the lowermost door section cross-part is biased by a spring or tensioning device in the vertical direction down, such a spring or tensioning device when starting up or opening the door curtain of this energy can tap and store. Similarly, the energy stored in the spring force can be returned to the door curtain.

It is within the scope of the invention that the second guide track section has a region which adjoins the upper end of the vertical area and extends predominantly horizontally. This is intended less for the bottom door section, but rather for the top door section, which has to face when closing the door curtain in the plane of the already vertically aligned gate sections.

The invention undergoes an advantageous development in that the predominantly horizontally extending region of the second guideway section extends, starting at the first, vertically extending region, initially slightly rising therefrom. This allows the top door section, which uses this guide section as the only, easily slide down when fully closing the door curtain; this movement has a stronger vertical component and is therefore triggered automatically by the weight; In order to follow this direction of movement, the upper free edge of the uppermost door section must move forward as desired along the guide rail and thereby automatically sets itself in the desired closed position.

On the other hand, the predominantly horizontally extending region of the second guide track section can transition into a horizontal course beyond its initially slightly rising course. In the area further away from the camber, the inclination of the uppermost door section equals the course according to the gently curved guideway and therefore does not require any supporting inclination of the guide rail anymore.

Additional advantages can be achieved in that the guideway (s) are formed as U- or C-profiles, the two legs serve as mutually facing raceways, which loosely engage around the guide rollers, so that they can easily roll it. The guide rollers can not accidentally slip out of the guide rails: a lateral displacement of the door curtain prevent those two legs of the U- or C-profiles connecting central webs, and an undesirable movement forward (outside) or rear (inside) is due to the front and rear thigh impossible.

Another design rule is that a first rocker is disposed between the lower end of the first arcuate track portion and the vertical portion of the second track portion. The current position of this rocker decides when Lifting the door curtain, ie during its opening movement, about whether a guide roller takes the lower, gently curved guide path or the upper, still vertically upwardly extending guide path. The latter route normally only takes the lead role of the lowest door section; all other guide rollers follow the gently arched path towards the horizontal guideway section.

A second rocker is located between the upper end of the first arcuate track portion and the horizontal portion of the second track portion. The task of this rocker is, when lowering the door curtain, so in the closing movement, the guide roles each communicate the correct path - either the lower, gently curved downward guide path or the upper, further horizontally forward towards the camber running guide. The latter usually only takes the lead role of the top door section; all other guide rollers follow the gently arched path towards the vertical track section.

The invention further provides that each rocker is designed in the manner of a two-armed lever, of which a preferably larger and / or longer lever portion is formed in the manner of a switch tongue, of whose two flanks depending on the position of the rocker each one part of the track for forms the guide rollers, while the other lever portion serves as a control lever for reversing the rocker. Bevoerzugt the control lever is in each case on the side of the gently arched, lower track path, because the respectively attached to the penultimate door section actuator moves along this path while the control lever can reach well. Since the rocker in question is to be moved by the actuator in the gently curved guideway path in order to block them and thereby open the other guideway path, the actuator engages a the actual switch blade lever with respect to the articulation point of the rocker opposite control lever; therefore, as the joystick is moved away from the smoothly curved guide path, the switch tongue lever will swing into it.

By the trained as a switch point lever portion of a rocker tapers at its free end, resulting in spite of the freedom of movement of the rocker only a comparatively small space requirement.

Each of the two longitudinal edges of the lever section of a rocker designed as a switch tongue assumes the function of a section of a track path, in particular of a leg of the U-shaped or C-shaped cross-sectional profile. Since one of the two track paths follows a gently arched, arcuate course, while the other runs straight, one edge must have a different course and the other a straight course.

Thus, the reversal of a rocker is as smooth as possible, the control lever for reversing the rocker at its end may have a rotatably mounted actuating roller which can roll on an actuating element grazing along it.

For proper operation of the lower rocker between the curved and the vertical guideway section whose control lever cooperates with an actuator on the second lowermost door section to open when passing the rocker due to the opening movement of the tank for the following leadership of the lowermost gate section, the vertical portion of the second guideway , In this case, the lever serving as a switch lever is directed downward against the vertical portion of the guideway; the control lever tends, however, in an approximately opposite direction, so that it is gently touched by the actuator lifting the door curtain and can easily retreat while swiveling the entire rocker about the bearing axis.

Finally, it is the teachings of the invention that the control lever for reversing the upper rocker between the first, curved and the second, horizontal track portion cooperates with an actuator on the second upper door section to the overrunning of the rocker in the closing movement of the tank for the following guide role the top door section to open the horizontal area of the second guideway. While the lever acting as a switch tongue is directed upwardly to the horizontal portion of the track, the control lever tends to be in the opposite direction so that it is gently touched by the actuator and can easily retreat while rotating the entire rocker about its bearing axis.

Further features, details, advantages and effects on the basis of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. Hereby shows:

7 one of the 6 corresponding representation of another sectional door from the prior art with a low fitting between the vertical and the horizontal guideway portion and consequently slightly smaller, but still relatively high camber dimensions;

8th a cut through the 7 , it can be seen that there are provided in the horizontal portion of the guideways two superimposed, mutually parallel guide rails;

9 a vertical section across the door curtain of a previously known from the prior art Schwingtors with ceiling rails, which oscillates far to the outside; such as

10 one of the 9 corresponding representation of another swing door from the prior art, without ceiling rails, which also swings far out.

The sectional door according to the invention 1 according to 1 to 5 comes thanks to a sophisticated construction with a 60 mm high lintel 2 for example, a sheet metal lintel or a U-shaped steel lintel. Thus, the clear passage height with the same dimensions is about 300 to 400 mm larger than a sectional door with normal fittings or about 100 to 200 mm larger than a sectional door with low fittings. This is made possible on the one hand by a perfected roller guide for the guide rollers 3 the individual door sections 4 , as well as the other by the coupling of the invention or the manual operation facilitating energy storage.

As you can see from the drawing, the gate armor is divided 5 of the sectional door 1 in several, elongated, stacked and articulated door sections 4 , In the area of the transverse longitudinal edges 6 the door sections 4 are each adjacent door sections 4 via arranged on the inside hinge elements 7 hinged together. In the area of the front sides of the door sections 4 carry the local hinge elements 7 each a storage for a leadership role 3 , Other leadership roles 3 can in the area of free longitudinal edges 8th the lowest and highest door sections 4 be provided.

These leadership roles 3 run in guideways 9 on both sides of the clear door opening 10 , These two guideways 9 each extending in a vertical plane, which is oriented perpendicular to the door curtain, and they are arranged in mirror image to each other; they each have a vertical section 11 along each side of the door opening 10 and a horizontal section each 12 , preferably along a ceiling 13 the garage concerned or a floor slab of another structure, as well as a transitional area 14 between the vertical and horizontal sections 11 . 12 ,

Each of the two transition areas 14 left and right of the door opening 10 consists in turn of two different paths, namely an approximately equally curved path 15 and on the other hand a significantly angular trained path 16 , These two paths 15 . 16 can from the leadership roles 3 optionally be traveled. Which path 15 . 16 a leadership role 3 takes, is each currently determined by one of two each reversible swing 17 . 18 whose function is comparable to that of a switch tongue.

In general, the guideways have 9 an at least L- or preferably C-shaped cross-sectional geometry. The C-shape comprises two legs approximately parallel to each other 19 . 20 , which at their outer edges, that of the respective gate opening 10 are turned away, through a central web 21 connected to each other. This middlebridge 21 lies respectively in or parallel to the plane of the relevant guideway 9 , The axes 22 the leadership roles 3 are directed perpendicular to this middlebridge level. In an L-shaped guideway section missing one of the two legs 19 . 20 , This is the case, for example, in the area of reversible rockers 17 . 18 , There are missing the thighs 19 . 20 in the area of the gusset between the two paths 15 . 16 and are replaced if necessary by the swingarm 17 . 18 if the same from the respective path 15 . 16 is moved out and then at least partially forms its edge. As you can see from the drawing, the wings have 17 . 18 an elongated figure with a front, thin end 23 and a rear, thick end 24 , At its thicker end 24 is a swingarm 17 . 18 stored, in the area of the twig between the two paths 15 . 16 , outside every guideway 9 , The free end 23 a swingarm 17 . 18 You can choose between one of the two paths 15 . 16 be swung in to close it and at the same time the other path 16 . 15 for the role in question 3 to open.

The wings are equipped with their controls 17 . 18 in the area of her rear, thickened end 24 or even beyond the same over a there about radially projecting control lever 25 , Passing by example a specially prepared door section 3 becomes such a control lever 25 If necessary, a piece of the way taken along and puts the switch tongue or swingarm 17 . 28 for the immediately following leadership role 3 and then directs those on the other path 15 . 16 , The length and direction of a control lever 25 should be sized and aligned so that an actuator on a door section 4 , preferably on a second upper door section 4 or at a second lowest door section 4 , the relevant control lever 25 just as far along, until the swingarm 17 . 18 from a path 15 . 16 is completely moved out and straight with the adjoining area of a thigh 19 . 20 the guideway 9 Aligns, giving a leadership role 3 as a substitute for the missing leg in this area 19 . 20 at a local peripheral edge of the swingarm 17 . 18 rolls along.

As can be seen from the drawing, the advantage of such an arrangement is that, although the large central part of the door curtain 5 over the gently curved path 15 gently from the vertical track section 11 to the horizontal guideway section 12 is deflected, while the bottom and top door section 3 go your own way, namely on the much more pointed path 16 move, but only up to about a local kink, which is not completely run over because of the Torpanzer 5 previously taken his full opening or closing position.

During the Torpanzers 5 So that by and large follows a very sophisticated movement, exactly these two end positions, ie the opening position on the one hand and the closing position on the other hand, can cause problems, because either the top door section 4 or the bottom door section 4 after switching a swingarm 17 . 18 takes a slightly different route than the previous, middle gate sections 4 , and therefore, so to speak, from the coherent "train" of the successive gate sections 4 "Veering". Although this Ausscherbewegung leads to favorable results, but is of the relevant Torsektion 4 not automatically taken over, but rather reluctantly, because they are actually the previous gate sections 4 would like to follow.

As a remedy, the invention provides a special type of control mechanism for the door armor 5 in front. This consists inter alia in that the drive of the door curtain 5 either exclusive or supportive to the bottom door section 4 he follows. The lowest door section 4 stays with her leadership 3 always within the vertical section 11 the guideway 9 which may be within the more pointed path 16 the transition area 14 continues in a joint flight.

The coupling of a drive or a drive support is inventively in the range of the axis 22 the leadership role (s) 3 in the area of the free, lower longitudinal edge 8th the lowest door section 4 instead of.

For coupling between the actual drive or a drive support, for example in the form of an energy storage, a flexible traction means 26 used, for example, a steel cable or a metal chain od. Like. This is at its lower, free end, for example, to an eyelet or sling 27 shaped, which is the axis 22 the relevant leadership role 3 wraps around or embraces. So that the torpedo 5 can not tilt and thereby jam, the invention recommends, in each case such a traction device 26 on both sides of the clear door opening 10 to provide, each mirror image of each other. Both traction means are preferred 26 combined and coupled with a common drive or a common drive support, so that they are always driven simultaneously with each other.

A traction device 26 runs inside or near the C-shaped profile of the vertical section 11 the guideway 9 upwards to about the ceiling 13 or floor ceiling, and / or up to the fall 2 , There - behind the fall 2 and hidden from it - is located in each case a pulley 28 for a traction device 26 , This pulley 28 wraps around the traction device 26 for example, along a center angle of 90 ° and then approximately parallel to the horizontal section 12 the guideway 9 up to a drive or up to a drive support 29 in the form of an energy store, in particular a spring store, which can be designed as a torsion spring or multiply, preferably around a core, wound spiral spring.

Undoubtedly, by means of such an active drive or a passive drive support 29 the lowest door section 4 and thus the entire door armor 5 from the lowermost - closed position to the uppermost - fully open - position. It will be against the weight of the torpedo load 5 the lowest door section 4 pulled up and pushed the torpant standing on it 5 in front of him. During its upper sections the gently curved path 15 to the horizontal section 11 the guideway 9 can take an actuator at the second lower door section 4 the lower swingarm 17 from the curved path 15 to the first straight upwards running path 16 ,

Even if the bottom gate section 4 the area of transition 14 has reached, there are no terminals; rather, the undermanned leadership role 3 under the influence of the traction device 26 Continue straight up until the relevant leadership role 3 just below the pulley 28 located.

Even more - the coupling to the drive or a passive drive support 29 over the traction means 26 is so resilient that thus a possibly second energy storage 30 can be stretched, which is preferably to provide twice - each once on both sides of the clear door opening 10 ,

In the present example, a second energy store comprises 30 a vertical guide device 31 between the fall 2 and the pulley 28 , There is a sled in it 32 vertically movably guided by a spring 33 is biased into its lowest position. With the sled 32 is connected laterally in the direction of the local track section 9 cantilevered extension 34 , during the opening movement of the door curtain 5 from the noose 27 or eyelet at the lower end of the traction device 26 or from a part of the lowest door section coupled to it 4 is attacked and raised. This will be the spring 33 curious; excited.

This preloaded spring 33 can release its energy again when the drive or drive support 29 is moved in the reverse direction, so that the traction means 26 from a coil od. Like. Unwinds. In the moment is the complete Torpanzer 5 still spread evenly horizontally and therefore does not experience its own drive in the closing direction. This takes over the preloaded spring 33 , which tries to relax while the bottom door section 4 push down until the spring 33 has completely relaxed. But now the bottom door section hangs 4 Almost vertically down, and its own weight pulls on the door curtain 5 and supports its closing movement, so ideally next to the traction means 26 no further coupling with a drive or drive support unit 29 more is needed.

The further the closing movement has progressed, the stronger is the at the door armor 5 pulling weight of the already hanging door sections 4 , so that at this stage, the closing movement is extremely reliable.

As soon as the penultimate, so second upper door section 4 the upper swingarm 18 reached, they pressed the local Umsteuerhebel 25 and thereby moves the front, free end 23 the swingarm 18 down, leaving that of the previous leadership roles 3 chosen, gently curved path 15 now closed and instead the upper, initially further horizontal path 16 is opened. The leadership 3 the last, upper door section 4 therefore moves into the upper path 16 where she initially moves horizontally and thereby the fall 2 comes closer. However, at the last moment, the angle under which the weight of the goal armor 5 pulls, almost perpendicular to the horizontal area 35 of the upper path 16 , Therefore, the top door section could 4 just before swinging into the plane of the rest of the door shell 5 pinch and stop early. To prevent this, the upper part of the path is 16 in his front, the fall 2 facing area no longer exactly horizontal as the section behind it 35 but towards the fall 2 slightly inclined downwards, with this inclination near the camber 2 can get stronger and then along an arc in the vertical section 37 of the upper path 16 can go over. The inclined area 36 can be described as an approximation to a kind of lying parabolic curve whose vertices are at the beginning of the vertical section 37 From there, it becomes steeper and gradually flatter to the horizontal section 35 goes up. The effect of this inclined area is that the top door section 4 when closing the door curtain 5 also or just at the last moment still felt a vertically downward movement component, which when taking the lowest possible position automatically at the same time the foremost position exactly above the other door sections 4 of the Torpanezrs 5 assigns.

Thanks to a preferably over the entire door width extending connection axis in the region of the deflection roller 28 or the drive (support) unit 29 can the sectional door 1 be operated with all commercially available drive equipment, in particular beispielsweie means of electric motors or geared motors, etc.

The leadership roles 3 are preferably ball bearings to achieve optimum ease of movement.
