Description

The invention relates to a gate, in particular a sectional door or Seitensektionaltor comprising a plurality of interconnected panels, which are guided over rollers in guide rails comprises. In this case, the door leaf via a door drive at least from a fully open in a closed position can be transferred.

For closing the openings of buildings, garages or the like gates are commonly used, which there are in various embodiments, for example in the form of swinging doors, overhead doors, roller doors, swing gates or as sectional doors. In sectional doors, the door leaf consists of several interconnected panels, each guided over rollers in guide rails. In this case, these sectional doors are guided from a closed position into an open position by being guided along the guide rails under the ceiling, for example the garage.

For reasons of manufacturing costs, assembly costs and also for optical reasons, it is actually desirable to assemble the goal of as little as possible large panels. However, in order to be able to pull the rollers of the door along the lateral guide rails, it is necessary that the width of the successive panels is comparatively small, so that the pairs of rollers without polygons can run along the guide rails. The wider the individual panels become, the greater the radius of the curved transition region of the guide rails to ensure smooth running. A comparatively large radius of the transition region of the guide rails in turn leads to a large fall above the opening, which is to be closed by the garage door. Thus, sectional doors with large panels are essentially suitable for construction situations in which above the door opening there is sufficient space for arranging the guide rails. Straight prefabricated garages, in which only a relatively low lintel is provided, but can not be provided with sectional doors with large panels as a rule, since there is no high enough fall available.

On the other hand, it is desirable that even when closing with a gate on request, an air exchange with the environment is achieved. For this purpose, it is already known to use various ventilation systems. In this case, for example, the top panel can be provided with ventilation slots. Alternatively, the lowest panel in the region of the closing edge can also be provided with a combination of a sealing and ventilation profile.

Regardless of the known solutions ventilation systems are also known in which the top panel is folded away in the fully closed position of the door by a pivoting inward to allow an exchange of air separated by the gate area with the environment.

From the DE 20 2006 013 676 U1 a solution is known in which the door leaf is thereby transferred to a ventilation position that the already existing door drive is used for moving the door leaf at the same time to tilt the door leaf in a ventilation position. In this case, however, the gate is pivoted by the driven by means of the door drive driver in an area of the uppermost freely tiltable panel, the entire gate is lifted by a gap from the ground. This results in a ventilation gap in the floor area and a ventilation gap in the upper panel area. However, the formation of the cleavage region on the bottom is undesirable since pests, such as rats or mice, can slip through the gap. In addition, a burglar could also use a suitable Stemmwerkzeugs the gate after the formation of the corresponding gap easier to pry open. To prevent this, sees the DE 20 2006 013 676 U1 a separate locking device that secures the door leaf in an approachable ventilation position.

From the DE 20 2008 001 121 Another solution is known in which the top panel of a multi-panel door panel can be tilted without creating a gap between the floor and a floor-near panel (bottom panel). The tilting functionality of the top panel is achieved by passing a pair of rollers in communication with the topmost panel in a separate guide rail. The course of the disclosed in this document guide rail is discussed in detail later Fig. 1 shown. It can be seen that the guide rail for the top pair of rollers running substantially horizontally, then merges into a downward bend, which merges at a kink directly into an upward bending. To tilt the uppermost panel, the upwardly extending bend of the guide rails extending from the kink is used to allow tilting of the panel.

A disadvantage of the above-described embodiment is that the travel speed of the door leaf or the panels are lowered to zero must, if the top pair of rollers reaches the kink, ie the low point of the specially provided for the top pair of rollers guide rails. At this point, namely, the slope of the guide roller provided for the upper pair of rollers abruptly changes, so that the traversing speed of the door or the pair of rollers on reaching this kink very much throttled or even reduced to the value zero or a value close to zero. For this purpose, a particularly accurate sensor is needed to reliably determine the point of reaching the kink. Furthermore, it is disadvantageous for the traversing motor of the door leaf or for the door drive that during a closing or opening operation the motor drive can not simply start and stop, but that at the predetermined point, namely when the kink point is reached by the uppermost pair of rollers, the motor drive must be selectively braked before it can start again. It is clear to the person skilled in the art that this inevitably leads to a shortening of the overall service life of the drive, since starting and braking down of the drive belong to the most wear-intensive states of a drive.

Starting from the known prior art, the object is to develop a generic goal such that it makes it possible to perform the drive of the door less robust and still maintain the Kippfunktionalität. Of course, it should also be ensured that the door touches the ground during the ventilation position.

This object is achieved by a gate according to claim 1.

Accordingly, the door, in particular a sectional door, may be a door leaf having a plurality of interconnected panels, pairs of castors associated with one of the plurality of panels and adapted to guide a respective panel into guide rails, the door a top pair of rollers, a bottom pair of rollers and at least one middle pair of rollers includes, and the top roller pair, the bottom pair of rollers and the at least one middle pair of rollers in each separate Guide rails run. The gate according to the invention is further characterized in that the guide rails of the upper pair of rollers have a course which has a trough-like shape at a portion.

The course of the guide rails for the top pair of rollers has a trough-like shape, so in comparison to a rectilinear extent has a bulge thereof. This results in the advantage that tilting of the uppermost panel for ventilation of the space to be closed with the door is possible by the upper pair of rollers, which is in communication with the uppermost panel, is moved into the trough in the direction of the trough bottom. In this case, only a tilting movement of the uppermost panel is triggered, so that a pulling movement of the other panels, which would lead to the opening of the gate, does not take place.

In addition, it is advantageous for the drive of the door that the travel speed must be decelerated from an open state of the door to a closed state of the door only at a start and an end point and not as in the prior art at a kink in the guide rails associated with the top roller pair. It is clear to the person skilled in the art that the trough shape does not have any kinks which would necessitate such a behavior.

Another advantage is that there is no longer the need for sensors that cause stopping of the top pair of rollers at exactly the kink with high reliability.

Overall, the trough-shaped in their course guide rail is better for the drive motor of the gate, since the braking and starting in the crease deleted. The trough-shaped guide rails namely contain no kink or a kink. In addition, the production of the provided for the top roller pair guide rails is easier than those provided with a kink.

Preferably, the course of the guide rails provided for the uppermost pair of rollers is formed in its trough-like section by two rectilinear guide rail elements. It is also advantageous if the two rectilinear guide rail elements are arranged relative to each other so that they form a V-shape. The V-shape is then created by a very open V in which the angle between the two legs of the V-shape is greater than 90 °, preferably greater than 120 °, more preferably greater than 135 °.

According to a further modification, the guide rails for the top pair of rollers and / or the bottom pair of rollers consist essentially of a plurality of interconnected linear guide rail elements, wherein preferably the trough-like portion forming two rectilinear guide rail elements are each connected at their mutually projecting ends with other guide rail elements, which are arranged on a common straight line. So there is a guide rail for the top pair of rollers, which is substantially rectilinear and is interrupted only by the V-shape generating guide rail elements.

According to a further optional embodiment of the invention, the course of the guide rails provided for the uppermost pair of rollers corresponds in its trough-like section to a differentiable function, which preferably has an arcuate, wave-shaped or trough-shaped form in the trough-like section.

This again takes into account the fact that the guide rail according to the invention for the uppermost pair of rollers has no kink. A differentiable function is characterized by the fact that the derivative at each position is unique, so has no peaks or kinks. By the feature after the travel of the uppermost pair of rollers through the guide rails correspond to a differentiable function or the guide rails provide a path of a differentiable Function, it is ensured that the guide rails for the top pair of rollers in their travel have no kink.

In addition, it is also possible that the uppermost pair of rollers can be located in the trough-like course of the associated guide rails when the bottom pair of rollers has reached its end position, and the gate is in a fully closed position when the top roller pair has passed through the trough-like course of the guide rails , Starting from an open state of the gate so runs the top pair of rollers into the trough, passes through the hollow valley and leaves the trough to achieve a fully closed state of the gate. A retraction of the uppermost pair of rollers from a state of the closed gate leads to a tilting of the uppermost panel when the uppermost pair of rollers moves in the direction of the trough. For reaching a tilt position, it is of minor importance, whether the top pair of rollers exactly at the bottom of the trough of the guide rails holds or not.

According to a further modification of the invention, the convex side of the trough-like portion of the course of the guide rails for the uppermost pair of rollers is oriented downwards, and / or the guide rails for the uppermost pair of rollers are aligned substantially horizontally.

The guide rails for the top pair of rollers have a straight section that merges into the trough-like section. In this case, the trough-like section falls out of the rectilinear section and then leads approximately to the height of the rectilinear section, after the Muldental has been passed. The thus formed guide rail is arranged substantially horizontally, wherein the horizontal orientation can be defined by the rectilinear portion. In this case, the trough is oriented so that the convex seen by the rectilinear portion is oriented downwards so in the direction of the ground.

Preferably, the guide rails for the uppermost pair of rollers are arranged so that the trough-like course closer end of a guide rail, the panels in a closed state of the door is closer than the end of the guide rail to the trough-like course. This expresses that the trough-like course of the guide rails is arranged near the panels in a closed state, so that the trough-like course can also cause the tilting function of the uppermost panel.

According to a further optional development of the invention, the course of the respective guide rails with its respective trough-like shape corresponds to a wave-like or trough-like course, which preferably falls from a straight section into a bend, thereby forming a first tub rim, with a further bend the tub bottom and with a last bend creates the second tub edge. Preferably, at the end of the second edge of the tub, the level of the rectilinear portion that merges into the first tub rim is substantially reached again.

Preferably, the uppermost pair of rollers extends over the entire travel during opening or closing of the door in its separate guide rails. The guide rails for the top pair of rollers are therefore only available exclusively to this pair of rollers and are not shared by another pair of rollers, for example, a middle pair of rollers or the lowest pair of rollers.

According to a further embodiment of the invention, the guide rails for the at least one middle pair of rollers comprise a substantially vertical and a substantially horizontal portion, which are each interconnected by an arcuate guide rail portion.

In addition, it is possible that the guide rails consist at least partially of sheet metal profiles. Guide rails which consist at least partially of sheet metal profiles are particularly easy to manufacture and very robust.

Preferably, however, the guide rails, in particular the guide rails for the uppermost pair of rollers in their bent portion of a plastic molding.

Furthermore, the invention comprises a gate according to one of the embodiments described above, which consists of two or more, in particular three or four panels.

According to a further optional modification of the invention, the door leaf via a door drive from a fully open to a closed position can be transferred. Alternatively, however, the door leaf can also be manually transferred from a fully open to a closed position, which is advantageous in the case of a defective motor, for example.

The invention further relates to a door operator for a gate according to one of the embodiments described above for moving a door leaf between a fully open in a closed position and vice versa with a drive motor, a guide means, a movable by the drive motor along the guide means driver, with the door leaf is connected, and a controller, wherein the drive is characterized in that on the controller when opening the door from the fully closed state first at least one ventilation position is approachable by the fact that the top panel is tilted, the top pair of rollers so in the trough-like Course of the associated guide rails is located.

Preferably, different ventilation positions can be set by tapping the uppermost panel in different tilt angles.

In Fig. 1 is shown in simplified form in perspective, a gate 90, which serves to close the opening of a prefabricated garage. This gate is already known from the prior art. Typical of the door known in the art is that the guide rails 91, in which the top roller pair 92 is guided, have a kink. The kink is identified by the reference numeral 93. The associated disadvantages have already been discussed in the introductory part of the application, which is why a further discussion is omitted.

Fig. 2 shows a section of a perspective view simplified in a simplified form 1, which is designed as a sectional door. It has a total of three panels 21, 22, 23, which are articulated in a known manner to each other.

The lower edge of the lowermost panel 21 forms a closing edge in a likewise known manner. On the panels roller pairs 31, 32, 33 are arranged, of which only a part of the pair is visible. An uppermost pair of rollers 33 is disposed laterally at the uppermost end of the upper panel 23, respectively. A first middle pair of rollers 32 is arranged in the upper area of the panel 22 adjoining the top panel, while the bottom panel 21 has a pair of rollers 32 in its upper area and a pair of rollers 31 in its lower area near the closing edge. The pairs of rollers 31, 32, 33 extend in each case laterally arranged separate guide rails 41, 42, 43rd

Thus, a guide rail 42 of the guide rail system is provided for the middle pairs of rollers 32, which consists in a known manner of a vertical and a horizontal region and an arcuately connecting this area.

The gate 1 is in Fig. 1 completely closed, where it is drawn to transfer into a partially open or in an open state in a driver, not shown along the individual travel paths of the guide rails 41, 42, 43 upwards into the garage. In this case, from the closed state of the door 1, the uppermost panel 23 is first tilted to the rear, so that the uppermost pair of rollers 33 is located in the trough-like portion of the guide rails 43.

For a transition of the garage door 1 from a closed to an open state, a tensile force is applied near the upper edge of the uppermost panel 23 in the direction of the garage interior, which due to the trough-like portion 5 during the closed position to an open position and vice versa not braked or must be reduced to the value zero or a value close to zero.

Fig. 3 shows an advantageous embodiment of the invention in which the guide rails 42 of the at least one middle pair of rollers 32 are shortened. It is not necessary to run the central guide rails 42 to near a floor area or to extend over the entire length of the guide rails 43 for the uppermost roller pair 33. As in Fig. 3 As can be seen, this results from the fact that even in a closed state of the door leaf 2, the lowermost panel 21 with its middle pair of rollers 32 does not approach a ground-level area.

Conversely, this also applies to the uppermost panel 23, which does not reach the vicinity of the uppermost pair of rollers 33 in a completely opened state of the door 1 with its middle roller pair 32. Therefore, the guide rails 42 for the at least one middle pair of rollers can be shortened accordingly.

In the present embodiment, the gate equipped according to the invention has been provided with a door drive. However, the invention does not depend on the presence of a corresponding door drive. A gate according to the present invention can also be moved manually without departing from the spirit of the invention. As far as the gate is moved manually, the uppermost tilting panel can be provided with a lock to fix this in a desired ventilation position and / or secure.

Fig. 4a shows a further embodiment of the invention, in which the guide rails 43, 41 for the top and the bottom pair of rollers are substantially connected by interconnected rectilinear guide rail elements.

It can be seen that the guide rail 43 for the uppermost pair of rollers is arranged substantially on a straight line from which only the trough-shaped form 5 deviates. This is carried out here by two rectilinear guide rail elements 51, 52 which together form a V-shape result. The two distal ends of the V-shape are connected to the arranged on a straight line guide rail elements.

The guide rail 41 for the lowermost pair of rollers consists of a combination of two substantially rectilinear guide rail elements.

The structure of the guide rails with the rectilinear elements is advantageous in terms of manufacturing costs, since the materials used for this purpose do not have to be bent.

Fig. 4b shows the individual guide rails in a spaced-apart from the other guide rails view.

Fig. 4c shows the cross section of a guide rail. It can be seen in cross section that the guide rail has a running channel 61 in which the rollers or the rollers are moved. On one side of the trough 61 joins a side wall 62, which is typically used to make an attachment to a wall element of a building. In cross section perpendicular to the side wall 62 connects to a roof 63, which is to prevent the ingress of dirt. Between the protruding from the side wall 62 end of the roof 63 and the end remote from the side wall 62 of the chute 61 an opening is provided through which a connection is made with the guided in the guide rail gate.
