DESCRIPTION

Centering unit in conjunction with front closing elements for a door leaf in a sliding gate leaf

The invention relates to an arrangement of centring units in conjunction with vertical front closure elements for one of several sections of a gate leaf connected to one another in a rotatably movable manner, a door being integrated into the gate leaf, the door leaf also consisting of sections rotatably movable relative to one another. The gate leaf sections and the door leaf consist substantially of two spaced-apart metal sheets, the intermediate space of which is filled with an insulating material, the lateral vertical edges of the sections being closed by the front closure elements.

GB 372 919 describes a door support and guide means for holding a door in the correct position. Locking or unlocking of the door must therefore be facilitated. For this purpose, a plate is used which is provided with a pivoting pin which cooperates in another plate which is equipped with a slot. When closing the door, the pin is inserted into the slot, so that a defined closing position of the existing door is achieved.

Sectional doors are vertically opening building closures, the rigid sections of which are connected to one another in a pivotable manner by means of hinges and are designed to lie one above the other in the vertical position and can be moved in lateral guide arrangements. The individual sections consist substantially of two outer sheets arranged at a distance from each other, the intermediate space of which is filled with an insulating material. The outer ends of the sections of this type are closed by means of closing elements. In order to achieve the tightest possible closure of the sections of this type with one another, the individual sections are equipped with a profile on their upper side, with a complementary recess on the lower side of the sections.

In order to prevent sectional gates of this type from being opened continuously for the passage of people, the gate leaf can contain doors. These doors with their door leaves are constructed in a manner corresponding to gate leaves of the same shape. In order to prevent the operation of a gate from being blocked when it is moving on lateral guide elements, the integrated door must be securely in a suitable closed position.

Document FR2887283 discloses a centering unit for a gate leaf consisting of several sections connected to each other in a rotatably movable manner, a door being integrated into the gate leaf, which door leaf (12) also consists of several sections rotatably movable relative to each other.

The object of the invention is to provide a simple construction which offers a secure closing position of a door leaf integrated within a gate leaf, the door leaf and gate leaf consisting of several sections connected to one another in a rotatably movable manner. Furthermore, a water management should be provided which can be used effectively against incoming water from outside or condensed water originating in voids.

The objective of the invention is achieved by the features of claim 1. The subordinate claims which are incorporated into the main claim reproduce in this case a further configuration of the idea according to the invention.

The rigid sections of the gate leaf, as they are in the case of sectional gate leaves, are connected to each other by hinges. Due to the hinges of this type between the individual sections, the sectional gate can be more unstable overall than a one-piece gate leaf, depending on the size of the gate leaf. This unstable condition can be further aggravated by the fact that a door leaf is integrated into the gate leaf, which is connected to the corresponding sections of the gate leaf in a rotatable manner by means of hinges or pins. Such a door leaf within the gate leaf must not lead to the legal requirements being disregarded, in particular wind load absorption, water tightness, air tightness, noise damping and compliance with the required thermal resistance. It is particularly important for these features, which are shown but not limited to, that no heat exchange from the inside to the outside or vice versa to an unacceptable extent takes place between the sections in the closed position. Furthermore, due to the hinged configuration between the sections in conjunction with lateral guide rollers and guide rails, there is a large clearance for the entire gate leaf with freedom of movement in all directions. The individual sections of the gate leaf are themselves 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 gate leaf. In an incorrect closing position of the door leaf in the gate leaf, a complete movement is not possible. This would have a significant disruptive effect on the overall operation of the sectional gate.

Sectional door leaves, which have sections connected to each other in a rotatable manner, such as panels, cannot be sufficiently protected against water, noise, etc. entering from outside, for example through very strong wind pressure, due to their construction structure. In addition, condensation can form, for example on the door leaf. In particular, heavy rain in conjunction with wind loads directed at the door leaf can lead to water entering the building area behind it, but this is not desirable.

Sectional gate leaves with doors that open in the closed position also represent an additional disadvantage for water entering from outside. Small gaps can form between the gate leaf and the door leaf, and water can pass through them. If water still gets into the gaps between the gate leaf and the door leaf, it must also be drained out of the gate leaf.

The invention proposes an arrangement of centring units, in conjunction with vertical front closing elements, which simultaneously achieves the desired closure in the area of the profiling of the sections relative to one another and is also designed in such a way that the door leaf can be easily moved from its open position to its closed position within the gate leaf. For this purpose, the centring elements are each mounted on the lateral front closing elements, which close the individual sections of the gate leaf and the door leaf laterally, at the upper ends between the door leaf and the gate leaf. This results in a more secure and tight closure in the area of the profiling. This tighter closure can be understood from several perspectives. Firstly, with regard to a secure closing position of the door leaf on the gate leaf, but also with regard to the desired tightness against amounts of water or condensation water that arise from entering the gate leaf from outside. For this purpose, the centering unit parts and the front closing elements have openings or chambers that prevent any water from remaining between the door leaf and the gate leaf.

Furthermore, the closing process is substantially facilitated by the centring units of the arrangement according to the invention. In the prior art, centring aids are always fixed between the gate leaf and the door leaf at certain locations on the lateral closing elements, i.e. not at the upper ends of the panels. In particular, the placement of the centring units between the upper edges of the door leaf sections and the gate leaf sections ensures an improved connection between the door leaf and the gate leaf in the closed position in this area.

The centring unit consists of a first and a second part. After assembly, these parts are aligned opposite to each other in the sections of the gate leaf and simultaneously also in the sections of the door leaf. The first and second parts are designed so that in the closed position of the door leaf, a mutual engagement of the two parts occurs. This is achieved by forming a substantially horizontal or slightly oblique centring inlet in one of the parts, the opening of which is directed towards the door leaf being closed and is provided with chamfers on the outside. A rotating roller element is arranged on a projecting rigid shaft in the second part, which corresponds to the centring inlet of the first part in the closed position. The diameter of the roller element is then essentially adjusted to the opening width of the centring inlet, so that with sufficient clearance, a tilt-proof closed position of the door leaf can still be assumed. The overall stability of the gate leaf is substantially increased by the use of centring units between the individual sections of the door leaf and the gate leaf, so that the installation of the door leaf cannot represent any danger points. In order to achieve absolutely secure closing of the door leaf within the gate leaf, respective centring units are mounted on the respective equal upper panel ends on the left and right of the door leaf with the adjoining gate leaf elements. Such an embodiment increases the stability of the gate leaf as a whole.

The improvement of the water management of the sections in the area of the centring units is also accompanied simultaneously by a reduction of the air exchange rates in the corresponding buildings. For this reason, it is essential to drain the condensed water between the door leaf and the gate leaf via the centring units by means of drainage devices. Of course, the drainage must be carried out in such a way that the water to be drained is diverted in the direction of the outside of the gate leaf or door leaf. An advantage of the water management embodiment according to the invention is the possibility of quickly draining water accumulations inside the gate leaf or door leaf. For this purpose, a separate opening is provided, which increases the insulation properties of the door leaf and gate leaf. The drainage chambers in the front closure elements are designed so that they are aligned with the drainage openings of the centring unit in order to divert the water present. The large openings and chambers in the front sealing elements make it possible to prevent blockages, and in the event of blockages, cleaning is also possible in the assembled state using appropriate means.

In order to ensure effective water management with successful water diversion, the openings or louvers in the parts of the centring units are directly connected to corresponding chambers in the front closing elements for the passage of water of any kind. The good closing position, which is enabled between the door leaf and the gate leaf via the centring unit, can safely drain the water escaping from the empty spaces to the outside. This makes it possible to achieve effective drainage of the door and gate leaf in the lower area to the outside.

The parts of the centring units can be manufactured cheaply in a synthetic material version, for example from polyamide or similar, but the rotating rollers and the corresponding shafts consist of steel to prevent premature wear.

Another option for creating torsion-resistant door leaves within a sectional gate leaf is to use hinges or pins that are designed in a concealed manner between the door leaf and the gate leaf. Such hinges or pins provide the door leaf with a secure hold because they guarantee a precise installation compared to hinges that are simply supported.

The invention will be explained in more detail below using possible exemplary embodiments. Figure 1 shows a detailed representation of a sectional gate with panel sections in which a revolving door leaf is integrated.

Figure 12, closing elements arranged one on top of the other, assembled in sections with a first inserted piece.

The perspective view according to FIG. 1 shows a portion of a gate leaf 13 with an integrated door leaf 12. The gate leaf 13 consists of individual sections, which each extend laterally to the door leaf 12. The sections of the door leaf 12 and the gate leaf 13 have a similar structure and consist substantially of two spaced-apart metal sheets, between which an insulating material is inserted. These sections are inherently flexurally rigid and are each closed at their vertical end faces by means of end-face closing elements 21, 22.

In the door leaf sections 12 and the gate leaf sections 13, profiles 25 are formed in each case on the upper edge. These profiles 25 ensure a tight seal between the sections and one another, together with complementary configurations on the underside of the sections arranged above. Between the respective main closing edge of the door leaf 12 and the following gate leaf section 13, parts of a centering unit 1 are mounted on each side of the opposite sections at the upper end of the sections. Similarly, parts of the centering units 1 are also mounted on the adjacent closing edge between the door leaf 12 and the gate leaf 13. The upper sides of the centering units 1 have projections 11 which are adapted to the configuration of the profile 25 of the sections. By arranging the centering units 1 on the main closing edge and on the adjacent closing edge, a consistent closing of the door leaf 12 to the gate leaf 13 is achieved. This is achieved in particular because in areas where the gate leaf 13 and the door leaf 12 are unstable, namely in the upper end areas, a stable, yet also loose connection is achieved between the door leaf 12 and the gate 13. This leads to a substantial increase in stiffness under wind loads and also reduces heat exchange between the inner and outer sides of the sectional gate, which cannot be provided by the prior art.

A preferred embodiment of the centering unit 1, which consists of parts 2 and 3, is shown in a perspective view in Fig. 2. The direction of view to the centering unit 1 is shown in Fig. 2, seen from the inside of the gate and door leaf. The first part 2 and the second part 3 are each attached to the ends of the front closure elements 21, 22 in a connecting manner by means of fastening flanges 4, in which fastening holes 19 are contained. The first part 2 and the second part 3 have housings 5, 6 made of plastic. The housings 5, 6 have vertically continuous openings 27, 29 starting from the upper projections 11. An effective drainage of outgoing water can be achieved through these openings 27, 29. These housing configurations 5 and 6 enable easy positioning with the front closing elements 21, 22 on the one hand, and enable the centring means for the door leaf 12 to be produced at low cost on the other hand. Furthermore, in particular, sound insulation and a virtual air tightness can be achieved in conjunction with sealing gaskets (not shown).

The mounting of the first part 2 on the upper ends of the front closure element 21 can be seen, for example, from Figure 4. In this case, it is obvious that the projection 11 has been substantially adapted to the configuration of the profile 25. An additional sealing seal against heat loss is achieved by means of a cover 10 in front of the projection 11. At the same time, shock absorption is also achieved by means of the cover 10 when the door leaf 12 is moved into the closed position. A centering inlet 20 in the form of a recess is shown within the first part 2. The centering inlet 20 can have a slightly oblique or substantially horizontal development. By means of an insertion surface 32 running substantially straight and horizontally in the centring inlet 20, when the door leaf 12 is moved through the roller element 23, a very stable state of the door leaf 12 is immediately achieved in the door gate 13, and not only in the actual closed position of the door leaf as is the case in the prior art. The actual closed position of the door leaf 12 in the gate leaf 13 is further secured at the end of the centring inlet 20 by a closure 33 with a small recess. At the inlet of the centring inlet 20 there are chamfers 18 which facilitate the insertion of the roller element 23 which is rotatably arranged in the second part 3.

5 shows a possible embodiment of the mounting of the second part 3 on the door leaf 12. In this case, the housing 6 has a free section on the underside in order to be able to achieve a precise adaptation between the section and the front closing element 21, 22. An axle 24 is mounted in a rotatable manner within the housing 6 of the second part 3, a roller element 23 being rotatably formed on the axle 24. The roller element 23 has a bore on its periphery, not shown in detail, for lubrication between the roller element 23 and the axle 24 as required. In order to provide a lubricant reservoir in this case, one or more cavities can be made in the upper surface of the axle through which the lubricant is permanently supplied. The interaction of the roller elements 23 with the centering inlets 20 ensures a secure closing position between the door leaf 12 and the gate leaf 13.

At the same time, a stop tab 8 facing the outside of the gate leaf 13 is provided on the first part 2, next to which a recessed receptacle for a stop seal 14 is included. This is shown in FIG. 3, which also shows a receptacle for a closing seal 15 in front of the second part 3. In addition, the part 3 has a screen stop 9 facing the outside of the door leaf 12. For a secure sealing of the door leaf 12 to the gate leaf 13, a locking seal 16 is also shown on the inside of the first part 2. A lock, not shown in detail, is located inside the gate leaf 12, which can be operated by means of a latch 17.

Possible embodiments of the second part 3 of the centering unit 1 are shown in perspective views in FIGS. 6 and 7. In this view, the rotary roller element 23 is not shown with the associated shaft 24, but rather an shaft receptacle 26 extending through the entire second part 3 can be seen in FIGS. 6 and 7. In the region of the opening 27, the shaft receptacle 26 is surrounded by a spacer piece, so that the shaft 24 cannot lead to deformation of the part 3 when fastened to the second part 3. In the longitudinal extension through the second part 3, the opening 27 is shown, which extends through the entire housing 6 of the second part 3, so that water that arises despite the present fastening of the shaft 24 in the shaft receptacle 26 can easily penetrate here. A sealing channel 30 is incorporated into the screen stop 8, into which a sealing gasket for the door leaf 12 is installed.

The housing 6 of the second part 3 has the fastening bore 19 in the form of an elongated hole in its fixing flange 4. It is therefore possible to precisely position the second part 3 at the end of one of the front closure elements 21 or 22.

From Figures 8 and 9, the first part 2 of the centring unit 1 can be seen, which cooperates with the second part 3. The roller element 23 is inserted into the centring receptacle 20 in the closed position of the door leaf 12. At the end of the insertion surface 32 is the lock 33, which can have a slight recess with respect to the insertion surface 32 in order to thus ensure a secure closing position in the closed position of the door leaf 12 on the gate leaf 13.

The housing 5 of the first part 2 also has a longitudinally vertical penetration opening 29 or an opening channel through which any water present can be evacuated. The housing 5 is fixed and aligned to the required position by means of the fixing flange 4 in connection with the fixing bore 19 formed as an elongated hole in one of the front closure elements 21 or 22.

10 shows the installation of the first part 2 in connection with the front closure element 21. In this case, the first part 2 is placed on the upper end side of the front closure element 21. For this purpose, contour recesses 34 are provided in the front closure element 21 so that it can be installed on the upper end side of the front closure element 21 so that the upper projection 11 of the first part 2 is almost aligned with the profiling 25 of the upper part of the gate leaf 13 in its longitudinal direction. In order to secure the first part 2, the front closure element 21 has a stop surface 35 against which the fastening flange 4 is supported in order to be secured to the front closure element 21 via the fastening bore 19 in connection with a bore 36.

The configuration of the closing element 21 in the upper end region can be seen in Fig. 11. Here, it can be seen that the contour recesses 34 extend to both side walls of the shaft 37 as a continuous chamber. The shaft 37 is substantially aligned with the opening 27 or 29 of the centring unit 1. This ensures that any water accumulations that are present, which are almost invisible, can be diverted downwards towards the gate leaf end. In order to secure the front closing element 21, it has an installation lug 31 which is applied against the surfaces of the door leaf 12 or the gate leaf 13 and can be secured by means of bores 7, as can be seen from Fig. 1.

As already mentioned, the gate leaf 13 and the door leaf 12 are individual sections which are connected to each other in a rotatable manner relative to each other. To explain this again, reference is made to Fig. 12, in which two individual front closure elements 21 are shown one above the other and between which the first part 2 of the centring unit 1 is inserted to a certain extent. In this regard, it should be noted that this is also done with the front closure element 22 in connection with the second part 3.
