EP3929384B1 - Centering unit for a door leaf within a movable door leaf - Google Patents

Description

The invention relates to a centering unit for a door leaf consisting of several sections that are connected to one another in a rotatable manner and into which a door is integrated, the door leaf of which also consists of sections that can rotate with one another, as well as to a sectional door whose door leaf has an integrated door with such centering units.

In the GB372 919 A door support and guide device is described to hold a door in the correct position. This is intended to facilitate the locking and unlocking of the door. For this purpose, a plate is used which is provided with a rotating bolt which interacts with another plate which is equipped with a slot. When the door is closed, the bolt is inserted into the slot so that a defined closing position of the existing door is achieved.

A door with a sectional door that can be moved between a closed position and an open position reveals the EP 2 698 495 A2 A door is integrated into the door leaf, with at least one ramp-like guide surface in conjunction with a guide means being provided for assuming the closed position. The guide means is equipped with a rotating contact surface which comes into contact with the contact surface of the guide surface during the closing movement of the door leaf.

Another sectional door gives the FR 3 051 821 A1 This sectional door has a passive mechanical safety device that is a wicket door in such a way that the wicket door is prevented from opening when the sectional door is moved into the open position.

The DE 20 2017 106 659 U1 shows a wicket door with a door leaf that is pivotally mounted in a door opening of a gate. On a second narrow side of the wicket door, opposite the first narrow side, there are locking means that automatically form a locking connection when the wicket door is closed.

Another sectional door with a door reveals the FR 2 887 283 A1 .

Sectional doors are vertically opening building closures whose rigid sections are connected to one another via hinges and are designed to stand one above the other in the vertical position and can be moved in lateral guide arrangements. The individual sections essentially consist of two outer, spaced-apart sheets, the space between which is filled with an insulating material. The lateral, outer ends of such sections are closed by closing elements. In order to achieve a largely tight seal between such sections, the individual sections are equipped with a profile on their upper side, with a complementary recess on the underside of the sections.

In order to avoid having to constantly open such gates to allow people or small vehicles to pass through, doors can be included in the gate leaf. These doors and their door leaves are constructed in the same way as the gate leaves. In order not to block the operation of a gate during movement in lateral guide elements, it is necessary that the integrated door is securely in a properly closed position.

The object of the invention is to provide a simple construction that ensures a secure locking position of an integrated door leaf within a gate leaf, whereby the door leaf and the gate leaf consist of several sections that are connected to one another in a rotatable manner. Furthermore, a water management system is to be provided that can be used effectively against water entering from outside or condensation forming in gaps.

The object of the invention is achieved by the features of claim 1 for a centering unit and by the features of claim 6 for a sectional door with such centering units. The subclaims following the main claim represent a further embodiment of the inventive concept.

The rigid sections of the door leaf, as they are designed for sectional door leaves, are connected to each other with hinges, for example. Depending on the size of the door leaf, such a construction can make the sectional door more unstable than a one-piece door leaf. This unstable situation is further exacerbated by the fact that, for example, a door leaf is integrated into the door leaf, which is connected to the corresponding sections of the door leaf via hinges or hinges. However, such a door leaf within the door leaf must not lead to the legal requirements, in particular wind load absorption, watertightness, airtightness, sound insulation and compliance with the required thermal resistance, being neglected. For these aforementioned features, it is particularly important that there is no increased heat exchange between the sections from the inside to the outside, or vice versa, in the closed position. Furthermore, the hinge design between the sections, in conjunction with lateral guide rollers and guide rails, means that the door leaf as a whole has a lot of play. with freedom of movement in all directions. The individual sections of the door leaf are very rigid and do not cause any problems. It is important to achieve a correct closing position of the door leaf when integrating the door leaf into the door leaf, because if the door leaf is not closed correctly in the door leaf, it is not possible to change its position at all. This would significantly disrupt the entire operation of the sectional door.

Sectional door leaves, which consist of sections connected to one another in a pivoting manner, such as panels, are sufficiently protected due to their construction in the hinges of the connected panels, e.g. if they are not completely protected against water entering from the outside, noise, etc., for example due to high wind pressure. Condensation can also form, for example, between the door leaf and the door leaf. In particular, heavy rainfall combined with wind loads directed at the door leaf can lead to water entering the building area behind it.

Sectional door leaves that contain a door that can be opened in the closed position also pose an additional risk for water entering from outside. Open gaps can form between the door leaf and the door leaf, albeit to a small extent, through which water can penetrate. If water has entered the gaps between the door leaf and the door leaf, this must be drained away to the outside of the door leaf.

The invention proposes a centering unit that simultaneously fulfills the desired closure in the area of the profiling of the sections among each other and is also designed in such a way that the door leaf can be easily transferred from its open position to its closed position within the door leaf. For this purpose, the centering units are each attached to lateral front end elements, which close off the individual sections at the sides, mounted at the upper ends between the door leaf and the gate leaf. This creates a secure and tight seal in the area of the profiling. This seal can be understood in several ways, firstly in relation to a secure closing position of the door leaf in the gate leaf, but also with regard to the desired sealing against water penetrating from outside the gate leaf or the formation of condensation. For this purpose, there are openings or chambers in the parts of the centering unit and in the front end elements that prevent existing water from remaining between the door leaf and the gate leaf or from penetrating into the building.

Furthermore, the closing process is made considerably easier by the inventive centering units. In the current state of the art, centering aids are always attached between the gate leaf and the door leaf at some point on the side closure elements only on the main closing edge, i.e. not on the upper ends of the sections. Only the placement of the centering units between the upper edges of the door leaf sections and the gate leaf sections ensures a good and secure connection in the closed position between the door leaf and gate leaf in this area of the gates, which are subject to play.

The inventive centering unit consists of a first and a second part. After assembly on the end elements, these parts correspond to each other on the sections of the gate leaf opposite each other and at the same time on the sections of the door leaf. The first and second parts were designed in such a way that the two parts engage with each other when the door leaf is in the closed position. This is achieved by having a centering inlet in one of the parts that runs essentially horizontally or at an angle, the opening of which is directed towards the closing door leaf and is provided with bevels. In In the second section, a rotating roller element is arranged on a protruding, rigid axis, which corresponds to the centering inlet of the first section for a secure closed position. The diameter of the roller element is essentially matched to the opening width of the centering inlet, so that with sufficient play the door leaf can still be in a closed position that is secure from jamming. The overall stability of the door leaf is significantly increased by the use of the centering units between the individual sections of the door leaf and the door leaf, so that the installation of the door leaf can no longer represent a danger point.

Improving the water management of sections also means reducing the air exchange rates in the corresponding buildings. For this reason, for example, it is essential to drain condensate between the door leaf and the gate leaf using drainage devices. Of course, the drainage must be designed in such a way that the water to be drained is directed towards the outside of the gate leaf or the door leaf. One advantage of the water management design according to the invention is the rapid drainage of water accumulations inside the gate leaf or the door leaf. For this, it is necessary to provide a separate opening, which increases the insulating properties of the door and gate leaf. For this purpose, drainage shafts in the front end elements are designed so that they are aligned with drainage openings in the centering units in order to drain water that is present inside. The structural design of the centering units with the large openings and shafts in the front end elements means that blockages can be avoided, and the shafts can also be cleaned when installed using appropriate means.

To ensure effective water management with successful water drainage, the openings or breakthroughs in the sections of the centering units are connected to corresponding shafts in the front end elements, one above the other. The good closing position, which is made possible by the centering unit between the door leaf and the gate leaf, can safely drain water that occurs in the gaps to the outside. This makes it possible to achieve effective drainage to the outside of the door and gate leaf.

The parts of the centering units can be manufactured cost-effectively in a plastic version, although the rotating roller and the associated axle are made of steel.

Another option for creating torsion-resistant door leaves within sectional door leaves is to use concealed hinges between the door leaf and the door leaf. Hinges or hinges of this type give the door leaf a secure hold because they have a precise structure compared to hinges that simply rest on the door and have a lot of play.

a perspective view of a partially opened door within a door leaf

Through the perspective representation according to Figure 1 a part of a sectional door leaf 13 with an integrated door leaf 12 is shown. The door leaf 13 consists of individual sections, each of which extends laterally to the door leaf 12. The sections of the door leaf 12 and the door leaf 13 have an identical structure and essentially consist of two spaced-apart sheets between which an insulating material has been inserted. These sections are inherently very rigid and are each closed on their vertical end faces by front end closure elements 21, 22.

Profilings 25 are formed on the upper edge of the sections of the door leaf 12 and the sections of the gate leaf 13. These profilings 25 ensure that the sections are tightly sealed to one another in conjunction with complementary formations on the underside of the sections that interact with them. Between the main closing edge of the door leaf 12 and the adjoining sections of the gate leaf 13, sections 2, 3 of a centering unit 1 are mounted on the upper end of the elements on each side of the sections. In the same way, sections of the centering units 1 are also mounted on the secondary closing edge between the door leaf 12 and the gate leaf 13. The upper sides of the centering units 1 are provided with projections 11 that are adapted to the formation of the profiling 25 of the sections. By placing the centering units 1 on the main and secondary closing edges, a firm closure of the door leaf 12 in the gate leaf 13 is achieved. This is achieved in particular by creating a solid connection, but also a detachable connection, between the door leaf 12 and the gate leaf 13 in the area where the gate leaf 13 and the door leaf 12 are unstable, namely at the upper end areas. This leads to an increase in the rigidity of the gate leaf 13 in the closed position under wind loads and also reduces heat exchange between the inside and the outside of the sectional door.

A possible embodiment of the centering unit 1, consisting of the sections 2 and 3, is shown in a perspective view of the Figure 2 The direction of view of the centering unit 1 according to the illustration of the Figure 2 is shown as seen from the inside of the gate and door leaf. The first section 2 and the second section 3 are each attached to the upper ends of the front end elements 21, 22 in conjunction with fastening flanges 4, which contain fastening holes 19. The first section 2 and the second section 3 have housings 5, 6 made of plastic. The housings 5, 6 have openings 27, 29 starting from the upper projections 11. These openings 27, 29 can be used to effectively drain any water that forms in the gaps between the gate leaf 13 and the door leaf 12. This housing design makes it possible to position the door easily on the one hand and to design the centering means inexpensively on the other. Sound insulation and a quasi-airtightness can also be achieved in conjunction with seals (not shown).

The assembly of the first part 2 at an upper end of the front end element 21 can, for example, Figure 4 It is clear that the projection 11 has been adapted to the design of the profile 25. Additional sealing against heat loss can be achieved by a cover in front of the projection 11. At the same time, such a cover can also provide impact damping when the door leaf 12 enters the closed position. Within the first section 2, a centering inlet 20 is shown as a recess, which can have an oblique or essentially horizontal course. At the entrance to the centering inlet 20, bevels are provided which prevent a centering piece 18, which is rotatably mounted on the second part 3.

A possible mounting of the second part 3 on the door leaf 12 is given by the Figure 5 The housing 6 has a cutout on the underside to achieve a precise adjustment between the section and the attachment connection element 21, 22. An axis 24 is mounted in a rotationally fixed manner within the housing 6 of the second part 3. Such a design can, for example, be the Figure 9 can be removed. An axle holder 26 has two opposing surfaces on the inside, with which two flats 39 of the axle 24 together form an anti-twisting device. A rolling element 23 is rotatably mounted on the axle 24. The rolling element 23 has a bore 43 in order to achieve lubrication between the rolling element 23 and the axle 24. In order to provide a reservoir for lubricant, a groove 40 can be made in the surface of the axle 24, via which the lubricant is permanently provided. Before the axle 24 is assembled, the rolling element 23 must be placed on the axle 24 via its inner bore 42. Inside the rolling element 23, a shoulder 44 is incorporated at one end, into which the stronger projection 41 of the rolling element 23 is embedded. Only now can the axle 24 of the rolling element 23 be pushed together into the axle holder 26. The axle 24 is secured by a fastening screw 10. To ensure that the rolling element 23 remains rotatable at all times, a shoulder 38 of the axle 24 rests against a projection 46. The rolling element 23 is thus always freely rotatable. The interaction of the rolling elements 23 with the centering inlets 20 guarantees a secure closed position between the door leaf 12 and the gate leaf 13 under all circumstances.

On the first section 2, a stop 8 is provided facing the outside of the door leaf 13, next to which there is an undercut receptacle for a stop seal 14. This shows the Figure 3 , which also a receptacle for a sealing seal 15 can be removed from the second part 3. Furthermore, the part 3 has a cover stop 9 on the outside of the door leaf 12. To securely seal the door leaf 12 to the gate leaf 13, a sealing seal 16 is also shown on the inside of the first part. Inside the gate leaf 12 there is a lock (not shown) that can be operated by a door handle 17.

The centering unit 1 provides compensation in two directions, both between the sections of the gate leaf 13 and the door leaf 12, and also overall compensation between the gate leaf 13 and the door leaf 12 of the gate, so that smooth operation can be carried out.

In the Figures 6 and 7 Possible designs of the second part 3 of the centering unit 1 are shown in perspective representations. In these representations, the rotating rolling element 23 with the associated axle 24 is not shown, rather the axle holder 26 is only shown to the Figures 6 and 7 which extends through the entire second section 3. The axle holder 26 is surrounded by a spacer 28 so that the axle 24, when attached to the second section 3, will not lead to a deformation of the section 3. The opening 27 is shown in the longitudinal extension through the second section 3, which extends through the entire housing 6 of the second section 3 so that any water that accumulates can simply drain off here, despite the existing attachment of the rolling element 23. A sealing channel 30 is incorporated into the cover stop 8, into which a seal for the door leaf 12 can be inserted.

The housing 6 of the second part 3 has a fastening hole 19 in the form of an elongated hole in its fastening flange 4. This makes it possible to precisely position the second part 3 at the end of one of the end closure elements 21 or 22.

The Figure 8 the first part 2 of the centering unit 1 can be removed. For the run-off of the rolling element 23, which is not shown here, the centering inlet 20 has been shown, which has a flat inlet surface 32, which can have a substantially straight or sloping ascending course. At the end of the inlet surface 32 there is a closure 33, which can have a slight depression opposite the inlet surface 32, in order to be able to assume a secure closing position in the closed position of the door leaf 12 in the gate leaf 13.

The housing 5 of the first section 2 also has an opening 29 or an opening channel penetrating in the longitudinal direction, through which any water can also drain. The housing 5 is also attached to one of the front end elements 21 or 22 via the fastening flange 4 in conjunction with the fastening hole 19 designed as an elongated hole.

The installation of the second section 3 in conjunction with the front end element 21 is given by the Figure 10 again. The second part 3 has been placed on the front side of the front end element 21. For this purpose, contour recesses 34 have been made on the front end element 21 in order to be able to place the part 3 on the upper front side of the front end element 21. The upper projection 11 of the second part 3 is virtually flush with the profiling 25 of the upper part of the door leaf 13 in its longitudinal direction. To fasten the second part 3, the front end element 21 has a stop surface 35 against which the fastening flange 4 rests in order to be fastened via the fastening hole 19, in connection with a hole 36, in the front end element 21.

The end element 21 with the contour recess 34 can be located in the upper end area of the Figure 11 can be removed. It becomes apparent that the contour recesses 34 extend on both sides of a continuous shaft 37. The shaft 37 is essentially aligned with the opening 27 or 29 of the centering unit 1. This ensures that existing water accumulations can be drained down to the end of the door leaf in a virtually invisible manner. To attach the front end element 21, it has a contact leg 31 which rests against the surface of the door leaf 12 or the door leaf 13 and can be attached to it, as is the case with the Figure 1 can be seen.

As already mentioned several times, the gate leaf 13 and the door leaf 12 are individual sections that are connected to each other in a pivoting manner. To illustrate this once again, reference is made to the Figure 12 , in which two individual front end elements 21 are shown one above the other and between which the second part 3 of the centering unit 1 is inserted. It should be noted that this is carried out in the same way with the front end element 22 in connection with the first part 2.

The interaction of the two parts 2, 3 with a partially opened door gives the Figure 13 again. A band 45 has been provided between the gate leaf 13 and the door leaf 12 to ensure their safe movement. The band 45 consists of two parts, the distance between which can be adjusted.
