The adjusting device extends a door leaf-broad side, and includes an adjusting element that is attachable to a door-leaf main body in a telescopically movable manner. The adjusting device is adjustable in a vertical direction to adjust a height of a door leaf lower edge, and is firmly fixed to selectively adjust a position of the lower edge relative to the body. An auxiliary profile element forms a bottom portion of one of the broad sides, and is adapted to a profile of a lower side of the body.

Description

The invention relates to a door leaf for a door for closing a building opening according to the preamble of the attached patent claim 1, as it is known from WO 00/29 705 A is known, as well as provided with such a door leaf door.

Doors in or on buildings have a door frame - the so-called frame - and at least one usually about a vertical axis pivotally mounted wings, said forming this wing body is referred to in the jargon as a door leaf.

Building doors serve a variety of purposes. There are normal interior doors without special functions or doors with special functions such as smoke protection or fire doors or sound insulation and anti-burglary doors. For the basic task of the door to close a building passage, also energy aspects become more and more important in recent times.

With the invention, a pivotable about a vertical axis door leaf is to be created, which offers improved sealing in practice over conventional door leaves.

In order to achieve a good closure effect, in particular with regard to climatic conditions and / or to achieve the prerequisite for fulfilling special functions such as smoke protection, sound insulation, fire protection and / or burglary protection, building supervisory standards and the manufacturers of doors and door leaves give maximum dimensions for door gaps, in particular the lower door gap, and maximum limits for allowable deviations for the lower door gap. So far, it has been expected that compliance with such tolerances should not be a problem. The invention is based on the surprising finding that in the Practice the opposite is the case. Investigations have found that a very large proportion of doors installed in practice have an inadmissibly high lower door gap. One reason for this may be that other local craftsmen are responsible for providing the ground level than for installing the doors. In construction sites, floor coverings such as screeds or carpets are often laid without regard to the function of doors. The installation companies entrusted with the installation of the doors, which often takes place before the final completion of the floors, usually provide a much higher lower door gap in order to avoid later complaints because of a jamming of the door. The resulting lower door gaps lead to a high air permeability, which can have adverse effects on heating costs and can ruin special functions. It has already been proposed here some solutions which relate to a height adjustment of the pivotal mounting of the door leaf to the frame. However, this does not or not reliably solve the above-mentioned problem of mismatching. An unskilled mechanic responsible for installing the doors will still install a height adjustable frame slightly higher than allowed. The lower door gap can then be corrected to some extent by adjusting the height of the door leaf. But that is at the expense of tightness at the upper door gap.

From the GB 2 365 054 A as well as the GB 4 70 989 A is in each case a door leaf according to the preamble of claim 1 known, which is provided for better adjustment with a length adjustment for adjusting the door leaf length.

Also, especially for soundproof doors and smoke control doors, there are separate seals attached to the underside of the door panel, which are automatically lowered to close the lower door gap in the door leaf closing condition. The provision of these seals, the above problem is exacerbated, however, since these automatically lowerable seals must have a precisely positioned abutment on the ground.

From the aforementioned WO 00/29 705 A is also a door leaf according to the preamble of claim 1 is known. This door leaf is provided with the aforementioned lowerable seal and can be adjusted for better adaptation by means of the Längeneinstelleinrichtung in the door leaf length. The length adjusting device has an adjusting element formed from two plates welded together to form a unit, which as a unit is mounted in a telescopically displaceable manner on a door leaf main body and can be fastened there.

In order to create a door that can be produced more easily in large series, which on average provides a tighter closure in practice, a door leaf according to claim 1 is proposed according to the invention.

The door leaf is provided with a Längeneinstelleinrichtung for adjusting the door leaf length.

Instead of or in addition to the provision of additional or movable seals, the invention accordingly provides to make the door leaf itself adjustable in its length.

As a rule, the doors are installed in such a way that the frame is first anchored in the masonry by a door fitter. Then the flooring is completed by other construction companies. Then comes the door fitter after completion of the flooring again to the site and must find that the installation position of the frame no longer matches the actual floor level, then he can make by adjusting the length of the door leaf by means of length adjustment a subsequent adjustment of the door leaf. As a result, can be corrected too large bottom gaps between the top of a finished floor and the door leaf lower edge again. As a result, the position of the door leaf underside, to which possibly a separate seal to be provided is corrected corrected.

To adapt to different door leaf thicknesses according to the invention further provided that the length adjustment not only an adjustment, but on each of the two door leaf broadsides has a separate adjustment, which is variable in position to a door leaf main body to extend the door leaf total or shorten if necessary. Thus, different door leaf lengths or different bottom gap levels can be generated and / or handled on the two door leaf broadsides. For example, as well as a trained below with fold door leaf is independent of the seam height manageable.

Advantageous embodiments of the invention are the subject of the dependent claims.

In a preferred embodiment, the door leaf is telescopically extendable.

The length adjusting device is therefore preferably designed such that at least one of the two broad sides of the door leaf can be extended. For example, the respective broadside associated adjustment z. B. in the form of a telescope part or the like, which extends the broad surface forming outside of the door leaf in particular downwards. The adjusting elements of the length adjusting device are preferably slidably fastened to a door leaf main body. The adjustment elements preferably form the door leaf edges. There may be provided a plurality of adjusting elements, each forming the transition between the respective broad side and the first narrow side forming door leaf edge.

If the Längeneinstelleinrichtung is adjustable in a direction in the intended use of the door leaf vertical direction to adjust the altitude of the lower door leaf, especially a too large bottom gap can subsequently easily correct. Alternatively, a correction could also be achieved by lowering the door leaf layer, in particular in the case of a door leaf which is mounted in height-adjustable fashion on a frame, in which case an excessively wide upper door gap could be corrected by changing the length of the door leaf on its upper side. However, this possibility is already for optical reasons and off Handling reasons - several settings are necessary - less preferred.

For a permanent correction of an excessively wide door gap, it is further preferred for the position adjustment device to be firmly fixable in order to fix a position adjustment, once selected, of a door leaf edge relative to the door leaf main body.

For forming the adjusting elements is preferably an additional profile element, for example, a multi-part profile strip, which is suitable for extending the door leaf, used. This is preferably at a below in the intended use of the door leaf horizontally to be arranged narrow side, d. H. the bottom, the door leaf main body arranged. The additional profile element preferably forms a lower edge region of at least one of the two door leaf broadsides, more preferably the lower edge regions of both door leaf broadsides.

For example, the additional profile element is divided in the thickness direction of the door leaf in at least two sub-strips. The two sub-strips can then be fixed to each other according to the thickness of the door leaf in a corresponding position.

It is particularly preferred if the additional profile element has a profile which is adapted to the underside of the door leaf main body. As a door leaf main body can then be used, for example, the normal known from the prior art door leaf a functional door. At this door leaf main body formed from a standard door leaf can then according to the

Lower trained additional profile element to be arranged for extension. As a result, a correspondingly formed underside can also be obtained on the extended door leaf, so that this underside of the extended door leaf can also be used in accordance with the desired function. For example, at the bottom of the door leaf, a groove could be desired wide to accommodate additional Seals or Brandschäumer or reinforcing elements to meet a smoke protection, sound insulation, fire protection or burglar protection function to be able to record. With correspondingly adapted additional profile element such a groove continues to be present on the extended door leaf and usable accordingly. This is particularly advantageous for smoke protection or sound insulation functions in which a seal provided as a standard component must seal the bottom gap. This then needs a corresponding base on the door leaf underside, which is present at a defined distance to the threshold. Here you have already tried many times in the art to prevent subsequent adjustment of the threshold even too wide door gaps. However, this results in a corresponding increase in the threshold, which is unwieldy and functionally often undesirable. Just think of trolleys or the like, which should continue to pass the threshold. With the structure according to the preferred embodiment, the door leaf can be extended downwards and thus achieve an exact position of the door leaf underside and thus an exact position of the base for a seal or a movable sealing apparatus to a ground level later found on the construction site.

If the additional profile element completely surrounds the underside of the door leaf main body or at least its door leaf edges, the door leaf can be telescopically extended in an optically advantageous manner in the region of its broad side. At the same time the wrapper can be used as a guide device for the displaceability of the additional profile element.

For the above-mentioned reasons for obtaining special functions, it is preferred that the underside of the door leaf main body has a groove for receiving functional elements and the additional profile element acting on the underside has a corresponding engagement area for framing in this groove. Also, this groove can then be used as a guide device for guiding the adjustment movement in order to extend the door leaf. At the same time by the engagement of the additional profile in the groove on the underside of the additional profile, the creation of a corresponding space for receiving the then attachable to the additional profile Functional elements which are then displaced together with the additional profile element for adaptation to the ground level. Preferably, the wall regions bounding the groove of the door leaf main body are used to guide the adjustment movement of the additional profile element.

For this purpose, the engagement region of the additional profile element has a U-shape or L-shape. A web of the U-shape or a leg of the L-shape can thus be used for fastening or fixing the position of the additional profile element to the door leaf main body. This is done concealed in the groove, so that the door leaf extension can be made visually inconspicuous.

For forming an extension of the broad side (s) and / or for further guiding the adjustment movement, the profile of the additional profile element preferably has at least one surrounding area adjacent to the engagement area, which comprises one of the wall regions delimiting the groove of the door leaf main body.

In order to fix the set door leaf length, the length adjustment device preferably has a fastening device, by means of which the door leaf lower edge forming adjustment element in selectable distance to the underside of the door leaf main body is fastened.

In a preferred embodiment, the fastening device has at least one clamping (screw) element, in particular a clamping screw. With a deadlock can then fix the adjustment in a continuously selectable position in a simple manner.

The length adjustment device may further - as already mentioned above - have a guide device for guiding the adjustment movement. To fix the position, the length adjustment device can have one or more spacers. Additionally or alternatively, the length adjusting device may also have a biasing device that biases a relative to the door leaf main body adjustable adjustment in one of the displacement directions. Such a biasing device is particularly interesting in connection with an adjusting screw, as you can do so by simply turning the adjusting screw or the like by re-tensioning the extension of the door leaf.

Also, in addition to a setting on adjusting screws a positional fixation can be provided by a lock screw or lock nut.

In a preferred embodiment, the length adjustment device covers with a cover region a lower edge region of the door leaf main body in a manner displaceable relative thereto. If this coverage area is longer, in particular longer than 2 cm, it can additionally serve as a protection for the lower edge region of the door leaf broad side against kicks or the like in addition to any guiding function for the length adjustment.

In the Fig. 1 schematically illustrated door 1 has a frame 2 and a door leaf 3. The frame 2 is fastened in the region of a door opening to be closed on a masonry 4 of a building. The door leaf 3 is secured by means of door hinges 5 on the frame 2 pivotally. For setting and correcting a door gap 6 between the door leaf 3 and the bottom 7, the door leaf 3 - here at its lower edge region 8 on a length adjustment 9, with which the intended use of the door leaf height determining length L of the door leaf 3 is selectably adjustable.

The following is based on the Fig. 2-20 In more detail, various embodiments of door leaves 3 differ substantially in the nature and design of the length adjustment 9. Each corresponding parts of these embodiments are identified by corresponding reference numerals and each described only once. Here, a first embodiment of a door leaf 3a with a first embodiment of a Längeneinstelleinrichtung 9a in the Fig. 2-6 shown. A second embodiment of a door leaf 3b with the Längeneinstelleinrichtung 9b according to the second embodiment is in the Fig. 7 - 9 shown. The Fig. 10 - 12 show a third embodiment of a door leaf 3c with a Längeneinstelleinrichtung 9c according to the third embodiment. A fourth embodiment of a door leaf 3d with corresponding length adjustment 9d is in the Fig. 13 - 15 shown. And in the Fig. 16 - 23 5 shows a fifth embodiment of a door leaf 3e with a fifth embodiment of a length adjuster 9e. Finally, in the Fig. 24 - 26 6 shows a sixth embodiment of a door leaf 3f with a sixth embodiment of a length adjuster 9f.

All door leaves 3, 3a-3f have a door leaf main body 10, which is formed in a known manner from a box plate 11 made of steel and a cover plate 12 made of steel. The cover plate 12 forms a major part of a first broad side 13 of the door leaf main body 10, which is referred to below as the cover side 13. The box plate 11 forms a major part of the second broadside the door leaf main body 10, which is referred to below as the box side 14, and the two vertical narrow sides 15, 16 and the upper horizontal narrow side (not shown in detail). The door leaves 3, 3a-3f of the illustrated embodiments have a substantially formed by a bend of the cover plate 12 to corresponding edge strips of the box plate 11 fold, so that the width B _{D of} the lid side 13 is greater than the width B _{K of} the box side 14.

At the lower horizontal narrow side, which is referred to below as the bottom 18, the door panel main body 10, as in the case in question here Metalltürblättern, z. As sheet steel door leaves, is known, completed by a U-profile 19. This also referred to as a bottom profile U-profile 19 defined at the bottom 18 a rectangular cross-section groove 20 which is bounded by wall portions 21, 22, in turn, by the legs 23, 24 of the U-profile 19 and lower edge portions of cover plate 12 and Box plate 11 are formed.

Each of the length adjustment devices 9, 9a-9f has an additional profile element 25 arranged as a telescopic element on the underside 18 of the door leaf main body 10, a guide device 26 for guiding the displacement movement of the additional profile element 25 and a fastening device 27 for fixing the position of the additional profile element 25.

The additional profile element 25 is formed in the illustrated embodiments by two separately formed part profile strips 28 and 29. The lowermost edge region of the cover side 13 and the box side 14 of the entire door leaf 3, 3a-3f formed by the door leaf main body 10 and the length adjustment device 9, 9a-9f are respectively formed on the additional profile element 25. At the additional profile element 25 and the transitions of the two broad sides 13 and 14 to the bottom 18 forming door leaf lower edges 30 and 31 are formed, the distance from the bottom 7 forms the door gap 6.

A first 28 of the two part profile strips 28, 29 is associated with the cover plate 12 and forms the lower edge region of the cover side 13. The first part profile strip 28 has this one of the width B _{D of} the cover page 13 corresponding length. The second partial profile strip 29 is assigned to the box plate 11 and forms the lower edge region of the box side 14. The area of the second partial profile strip 29 having this lower edge region of the box side 14 of the entire door leaf 3, 3a-3f accordingly has a width B _K corresponding to the box side 14 Length.

Each of the part profile strips 28 has, as part of the guide device 26, an approximately U-shaped surrounding area 32, 33, with which it comprises the corresponding wall area 21, 22. The partial profile strips 28, 29 are thus plugged with their enclosure areas 32, 33 on the downwardly projecting wall portions 21, 22. This detection forms a displacement guide of the guide device 26, on which the two part profile strips 28, 29 are movable relative to the door leaf main body 10 upwards and downwards. When moving downwards, the door leaf 3, 3a-3f is telescopically elongated overall, so that the corresponding broad side 13, 14 is also extended. When moving upwards, the door leaf 3, 3a-3f or the corresponding broad sides 13, 14 is shortened.

The enclosing regions 32, 33 have an inner leg 50 and an outer leg 70, which forms a covering region 71 with which the length adjuster 9, 9a - 9f covers a lower edge region of the respective broad side of the door leaf main body 10.

While the common parts and components of the various embodiments of door leaves 3, 3a-3f and length adjustment devices 9, 9a-9f have been described above, the specific components of the individual embodiments will be described below with reference to the different representations.

In the in the Fig. 2-6 illustrated first embodiment of a door leaf 3a, the part profile strips 28, 29 of the length adjustment device 9a formed of sheet steel by cold deformation. The enclosing regions 32, 33 are of single-walled construction, wherein the surround region 32 in the groove 20 is in each case one bent edge strips 34, 35 connected in such a way that it extends parallel to the groove bottom formed by the web 36 of the U-profile 19. The additional profile element 25 formed from the two partial profile strips 28, 29 thus has a total of an approximately U-shaped profile corresponding to the shape of the underside 18 of the door leaf main body 10 simulated engaging portion 37.

At the edge strips 34, 35 holes 38 for receiving countersunk heads of fastening screws 39 are formed at regular intervals, which are parts of the fastening device 27.

Between the edge strips 34, 35 and the web 36 used depending on the desired length L of the door leaf 3a spacer 40 are provided.

On one of the two part profile strips, here on the first part profile strip 28, an additional bottom seal 41 is provided. The bottom seal 41 is optionally designed to fulfill a sound insulation and / or smoke protection function lowering at the transition to the closed state of the door 1. For this purpose, it has a main body 42 fixedly connected to the partial profile strip 28 and a sealing strip 43 movably received therein. By adjusting the partial profiled strip 28 by means of the guide device 26 and fixing by means of the fastening device 27, the position of the base body 42 matching the bottom 7 can thus also be adjusted.

The in the Fig. 7 - 9 illustrated length adjustment 9b according to the second embodiment of the door leaf 3b substantially corresponds to the first embodiment and differs from this only in that the two part profile strips 28, 29 not rounded in the region of the door leaf bottom edges 30, 31 bent sheet steel strips, but by extruded profiles, eg. B. of light metal, are formed, whereby the door leaf lower edges 30, 31 can be designed according to defined or sharp-edged. In particular, this can be achieved by a visually higher-quality appearance. Another difference of the second embodiment to the first embodiment is the formation of the bottom seal. In the Fig. 9 illustrated bottom seal 44th is in contrast to the bottom seal 41 of the first embodiment is not movable, but has a here formed by another extruded holding member 45 which holds a simple formed sealing strip 46 stationary relative to the corresponding part profile strip 28. This second embodiment is particularly suitable where an attached bottom sill 47 serves as an abutment for a sealing lug of the sealing strip 46.

Also in the Fig. 10 - 12 illustrated third embodiment of a door panel 3c is based in its basic features of the first embodiment. Here are the same part profile strips 28, 29 as used in the first embodiment. Only in place of the spacers 40, a biasing device 48 is provided in the third embodiment, which biases the two part profile strips 28, 29 away from the door panel main body 10. The biasing device 48 has here for each screw 39 of the fastening device 27 a screw this encompassing helical compression spring 49. The advantage of this third embodiment over the embodiments previously shown lies in the easy adjustment of the door leaf length L. When unscrewing the screws 39, the Teilprofilleisten 28, 29 under the bias of the helical compression spring 49 immediately follow accordingly. As a result, a continuously selectable adjustment of the two door leaf edges 30, 31 is possible.

In the in the Fig. 13 - 15 shown fourth embodiment of the length adjustment 9d, the two part profile strips 28, 29 are limited essentially to the enclosure areas 32, 33. The two edge strips 34, 35 are unnecessary here, but could also be present if needed.

In the illustrated fourth embodiment, an inner leg 50 of the two enclosing regions 32, 33 is designed so long that fastening means of the fastening device 27 can act on it. The fastening device 27 has for this purpose on these inner legs 50 engaging clamping devices 51, by means of which the part profile strips 28, 29 on the wall portions 21, 22nd can be clamped. For this purpose, the clamping devices 51 each have a threaded sleeve 52 and fixedly connected to the inner leg 50 a grub screw 53 inserted therein as a clamping screw. For adjusting the length of the door leaf 3d, distributed over the width of the door leaf 3d, ie the length of the part profile strips 28, 29 arranged clamping devices 51 are released, then the part profile strips 28, 29 along their leadership by the Umfassungsbereiche 32, 33 and the wall portions 21, 22nd shifted to the desired position, and then the clamping means 51 are brought into engagement by tightening the grub screws 53.

For reinforcement in the illustrated embodiment, the outer broad side 13, 14 formed with forming outer leg 70 of the Umfassungsbereiche 32, 33 reinforced by a refolding double-walled.

In the in the Fig. 16-23 illustrated fifth, the Längeneinstelleinrichtung 9e has as part of the fastening device 27 a plurality of retaining plates or mounting plates 54. One of each identically formed mounting plates 54 is closer in the Fig. 20 - 23 shown. The mounting plate 54 has on two opposite narrow sides 55, 56, which are to be arranged in each case parallel to the broad sides 13, 14 of the door leaf 3e extending, centrally arranged slots 57, 58, in which the edge strips 34, 35 of the part profile strips 28, 29 are receivable , The part profile strips 28, 29 are in the example shown (see Fig. 19 ) formed as extruded aluminum profiles, wherein the edge strips 34, 35 are formed much shorter compared to the first embodiment, so only over a fraction of the thickness direction of the door leaf 3, extend 3a-3f.

The wall portions 59, 60, 61, 62 of the fastening plate 54 bordering the slots 57, 58 are provided with notches 63 at specific intervals, so as to form predetermined breaking points for breaking off a part of these wall portions 59-62. Alternatively, here marks for cutting the wall portions 59 - 62 are provided by appropriate tool. Depending on the thickness of the door leaf main body 10 used, the fastening plates 54 are used in their entire width or with correspondingly shortened wall regions 59-62. As a result, the edge strips 34, 35 correspondingly extend further or less into the respective slots 57, 58. The mounting plates 54 serve so also as a spacer for Aufrecherhaltung a suitable spacing of the part profile strips 28, 29 in the thickness direction of the door panel 3e.

In the illustrated embodiment, each of the mounting plates 54 is provided with two holes 32 corresponding in function to the holes 38, on which the countersunk heads of the screws 39 engage. Next, each of the mounting plates 54 still has a threaded bore 65. In the threaded bore 65 a threaded pin 66 is screwed, which, as can be seen from the illustration of Fig. 19 results in one of the selected setting of the door leaf length L corresponding distance of the mounting plate 54 of the base 36 formed by the web of the groove 20 is maintained. By oppositely biasing the screws 39 and the threaded pin 66, the position of the mounting plate 54 is fixed.
