Independent claim describes method for mounting door by providing door panel with strip element, the door frame with strip element and prefitting the bearing members on the individual strip elements and inserting the projection into the recess by adjusting the bearing member.

Description

The invention relates to a door hinge according to the preamble of the appended claim 1, as known from US-A-1,103,607.

Furthermore, the invention relates to a door provided with such a door hinge, in particular Fire door, as well as methods for mounting and manufacturing such a door.

DE 24 12 725 A1 describes a door hinge for the pivotable mounting of a door a frame. The door hinge has a band element to be fastened to the door and an on the frame to be fastened band element. A first of these two band elements is from the second band element U-style overlapped, d. H. the first band element is between introduced two band element legs of the second band element. Between the two Band elements is a given axial movement play exists. The band elements are pivotally connected to each other via ball bearings as bearing means. One of the two bearing members, which are mounted on a ball as rolling elements together, is screw-like axially adjustable. Such trained ball bearings are on both Boundaries provided between the band elements.

By this known training a door hinge is created, which can easily be adjusted leaves to adjust the door leaf against the frame vertically. Thus, the well-known allows Belt system infinitely variable height adjustment for on-site adjustment.

Further adjustable door hinges are known from EP 0 293 050 B1 and EP 0 796 969 B1 known.

Disadvantages of DE 24 12 725 A1, EP 0 293 050 B1 and EP 0 796 969 B1 Known door hinges are their relatively complex structure, the need for a relative complex installation of the door hinge on the door leaf and / or the frame and the so accompanying relatively complicated assembly of such known door belt systems provided door.

From EP 0 569 818 A1, a door hinge with a first band element and two is in contrast pivotable about a pivot axis second band elements and with plain bearings known between the band elements. The two second band elements are parallel to the pivot axis displaceable in positive engagement with each other, whereby a pivot pin forming a bolt in axial receiving openings can be inserted. On This bolt can then be between the two band elements, the first band element hang hinged. At each separation point between the first and the two second band members each have a sliding bearing provided with a first bearing member, which is adjustably positionable in a direction parallel to the pivot axis. On this first bearing member is seated as a bolt engaging around the sleeve formed second Bearing member on. By taking place via threaded engagement on the second band elements axial positioning of the first bearing elements, the first band element can be relatively to the two second band elements in Schwenkachsrichtung for height adjustment of a Adjust the door with the door hinge. To disassemble the door hinge in order Allow removal of the first band element from the two second band elements the two second band elements in the axial direction from each other so as to remove the Release bolt. By the necessary engagement of the two second band elements each other, this door hinge is relatively complicated.

From the above-mentioned US-A-1 103 607, however, is a very simple trained Door hinge having the features of the preamble of the appended claim 1. Here is a first band element between two band element legs of the second band element added. In the band element legs are each first bearing members a slide bearing in an adjustable direction parallel to the pivot axis position adjustable added. By turning the first bearing members can be these in Schwenkachsrichtung position. The first bearing members each have pin protrusions, in a recess of the first band element with intermediate storage of a sliding bearing ring intervention. By the same direction turning the two first bearing elements can be a height adjustment of the first band element relative to the second Reach band element. The first two bearing members are formed maggot screw-shaped, However, have a greater lengths than tube sleeves of the two band element legs, with which they are in threaded engagement. Although this possibility is not in is mentioned in US 1,103,607, the bearing members could in principle as far as in opposite directions be unscrewed that the pin protrusions out of engagement with the first Band element arrive and so disassembly and in the opposite way mounting the door hinge is possible. To determine the adjustable first bearing members are on the upwardly and downwardly projecting threaded portions of the first bearing members Locknuts put on.

Starting from the prior art according to US-A-1 103 607 it is an object of the invention a door hinge having the features of the preamble of the appended claim 1 to improve so that while maintaining the simple and manufacturing and easy to assemble construction Operating errors when adjusting the door hinge provided door are avoidable as possible. This task is performed by a door hinge the features of claim 1 solved.

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

A door provided with the door hinge according to the invention as well as assembly and production methods are the subject of the further independent claims.

The door hinge according to the invention has a first band element and at least one second Band element, which is opposite the first band member about a pivot axis is pivotable. Between the two band elements sliding bearings are provided. The first band element is under intermediate storage of the sliding bearing between two band element legs of the second band member receivable. In an alternative embodiment the invention, two second band members are provided, between which the first Band element is receivable.

The plain bearings have on each of the band elements a first bearing member which is adjustable is positionable. The first band element is preferably in a direction to the pivot axis adjustable in parallel direction. A second bearing member is then at the other Band element provided.

By adjusting the first bearing member and the two bearing elements of the Slide bearing directly engaged or disengaged. To accomplish the procedure, the invention provides that the adjustable first bearing member projecting in the direction of the pivot axis pin projection Has. The second bearing member is provided with a recess for receiving the pin projection Mistake. By axial adjustment of the bearing member is thus the pin projection more or less engageable with the recess.

Instead of rolling bearings according to the invention is a sliding bearing between the band members intended. The plain bearing has the first bearing member and the directly or on this indirectly sliding seated second bearing member. By using a Slide bearing can avoid additional rolling elements, which are difficult to place. This requires a substantial simplification of the structure of the bearing means. simultaneously but is also the assembly of the door hinge itself and provided with the door hinge Door facilitates, since during assembly no additional rolling elements are inserted have to. This is particularly interesting with the adjustable bearing member, since by the Adjustability of the first bearing member not only an adjustment of the door leaf to the frame can be accomplished.

An advantageous embodiment of the invention allows extensive pre-assembly the door hinge on the door. This advantageous embodiment is characterized in that the pin projection has such an axial extent and arranged in such a way and is formed, that the two band members with bearing members pre-assembled thereto purely connected via adjustment of the first bearing member pivotally connected to each other or can be removed from each other. With appropriately deferred first bearing member is the first band element in the enclosure of the second band element used. In the alternative embodiment, the first band element is corresponding can be used between the two second band elements. In the inserted position can be by axial presentation of the first bearing member of the pin projection in the Insert recess. As a result, the band elements are in their pivotal engagement brought together.

On the basis of the above teachings, it will be clear to the person skilled in the art that such a design the pin projection is accomplished in a variety of ways. Please note while the interaction of the adjustability of the first bearing member and the movement play between the band elements.

According to the invention, the pin projection projects with an axial length which is smaller than is the axial displacement of the first bearing member.

The term "pin projection" is not limited to any shapes, such as a cylindrical shape, limited. The projecting pin could also be different Shapes, such as a cone shape, an ellipse shape, a hemisphere shape or have the same. To ensure the pivoting, however, are rotationally symmetric Formations of the pin and the recess preferred.

To a height adjustment of the first band element relative to the second Band member over a longer way to accomplish, according to the invention at each the two boundary points between the first and second band member with a plain bearing adjustable first bearing member is provided. By a parallel adjustment of the two first bearing members can then be an axial displacement of the two band elements relative accomplish each other, with the pin projections still safe in their respective Recesses remain inserted. For inserting the first band element Then the first bearing members of the two sliding bearings are adjusted to each other. And for axially adjusting the band members relative to each other, the first two Bearing members adjusted in the same direction to each other.

To prevent incorrect operation at the construction site or during subsequent adjustment avoid, according to the invention is a device for limiting the adjustment of the provided first bearing member. This device will be after the assembly of the two Door hinge elements attached to each other or adjusted so that a reset the first bearing member in such a way that thereby the positive engagement between the two bearing members is lifted, is avoidable. In concrete form could after the installation of the two wall elements together a Kunststoffpfropfen or a plug member provided on a first bearing member engaging thread be. This is done according to the invention such that the first bearing member still for Adjusting the vertical orientation of the door is movable, but not adjusted so far can be that the positive engagement is canceled.

According to the invention, the adjustable first bearing member is provided with the pin projection. Thus, by returning the bearing member of the pin projection out of the way are taken to steer the tape elements to each other or to each other remove.

The sliding surfaces of the bearing members engage one another in one embodiment. For this It is preferable that one of the two bearing members has a convex surface as a sliding surface and that other of the two bearing members has a complementary concave surface as a sliding surface.

Although the pin projection could also be provided on the concave surface protruding be. But the bearing members are easier to produce when the bearing member is provided with the convex surface with the pin projection.

Such training also has advantages in terms of a self-centering effect. The pin projection could when inserted into the with the concave surface and the recess provided bearing member first slide along the concave surface until it engages in the recess. Overall, the bearing members could tapered sliding surfaces exhibit. Also conceivable would be elliptical shapes.

Preferably, because relatively easy to produce, flat sliding surfaces, in particular provided with a sliding ring, or spherically shaped sliding surfaces. In a spherically shaped Sliding surface can also be a tendency of one of the band elements accomplish or handle relative to the pivot axis.

When the two band members are formed with approximately concentric with the pivot axis Pipe sleeves are provided, as in the prior art and many users is common, so can the door hinge according to the invention with already in use Make wall elements without major changes in the manufacturing process for this purpose.

As already known in principle from DE 24 12 725 A1 and US-A-1103607, the adjustability of the first bearing member is preferably realized by that to be provided with this band element concentric with the pivot axis trained axial opening with internal thread, while the first bearing member a has corresponding complementary external thread. The first bearing member is preferred formed like a screw. Preferably, facing away from one of the sliding surface axial side provided a tool engaging device. The first bearing member could be designed as a whole in the manner of an Allen grub screw. This design has the advantage that the first bearing member completely into the axial opening turn back the band element. With a completely pivoted bearing member the tape element is still paintable in preassembled state. Especially It can also be powder coated. The pre-assembled inside the band element Bearing member then remains free of coatings.

In an alternative embodiment, the first bearing member has a threaded shaft only at one end. Between the provided with the sliding surface end and the threaded shaft then a tool engagement area, such as a hexagon provided. Prefers The tool engagement area is provided with a plurality of radial openings into which a pin can be inserted, by means of which the bearing member can be rotated.

Preferred materials for the bearing members are steel, for example, the quality QSt 32-3 for one bearing element and C15 - QSt 36 - 2 for the other bearing element.

To facilitate or enable the sliding bearing properties can also special Surface coatings or the like may be provided on the sliding surfaces. easily usual lubricants are used. It is also possible to use a Gleitzwischenringes made of plastic, such. As Teflon or the like.

To the reliability and reliability of a door hinge with the invention provided further door, it is further preferred that the adjustable first Bearing member is associated with a locking device, with the position of the first bearing member can be secured. This can for example be a safety screw in the form a grub screw or the like. By the locking device is the first Bearing member prevented from relocation. It is thus ruled out by unintentional displacement of the first bearing member an unwanted lowering or lifting of the door leaf provided with the door leaf enters or even the pin projection passes from the detection with the recess. The setting is especially at a by turning adjustable first bearing member advantageous. Such a twist could occur unintentionally during operation of the door due to excessive frictional engagement on the sliding bearing. This could cause the bearing member to move out of position and open the and closing function or the attachment of the door leaf to the frame are affected.

With the locking device on the one hand, the once set position is obtained. To the other, the pin projection can not by unwanted displacement of the first bearing member get out of its detection in the recess, so that a Verdrehbegrenzung, as provided in an embodiment of the invention is dispensable. Finally, the pin projection can engage deeper into the recess; one possibly Resulting increase in friction due to the locking device not to an unwanted twisting or other displacement of the first bearing member.

A door provided with a door hinge according to the invention, in which the one band element is attached to the door leaf and the other band member is attached to the frame draws itself by a simple mounting option with simultaneous adjustability of door leaf and frame off.

Both band element legs 8 and the wing part 4 each have a substantially cylindrically shaped tubular sleeve 10, 11, whose axis of symmetry substantially with the later pivot axis 12 of the Door hinge 2 coincides. To the tube sleeve 11 of the wing part 4 is a wing band 14th attached for attachment to a door leaf. The band element legs 8 are through a Linked frame band 16 which is to be attached to the frame. At the border posts 18 between the tube sleeve 11 of the wing part 4 and the two tube sleeves 10 of the frame part 6 bearing means in the form of a respective sliding bearing 20 are provided.

Each slide bearing 20 has, as best seen in Fig. 3, a in the direction of Swivel axis 12 axially adjustable first bearing member 22 and a second bearing member 24th on. In the embodiment of Fig. 3, the first bearing member is in each case in the tube sleeves 10 each band element leg 8 used. For this purpose, the inside of the tube sleeves 10th provided with an internal thread 26. The outer ends of the tube sleeves 10 are respectively closed by a cover button 28. The second bearing members 24 of each sliding bearing 20 also close cover button similar to the two ends of the tube sleeve 11 of the wing part from. The second bearing member will be described below with reference to the illustration of FIGS. 6-7 explained in more detail.

The second bearing member 24 has approximately a hat-shaped shape with a flange 30 and an insert 32. The insert 32 is used for insertion into the tube sleeve 11, 10 of the band members 4, 6. It has an outer diameter D ₃₂ , by a few hundredths of a millimeter is larger than the inner diameter of the tube sleeves 10, 11 in order to be firmly clamped therein. To facilitate the introduction, the free end of the insert 32 is provided with a chamfer of about 15 °. The flange 30 serves to rest on the axial end of the tubular sleeve 10, 11 and has an outer diameter D ₃₀ , which corresponds approximately to the outer diameter of the tubular sleeve 10, 11. The axial end provided with the flange 30 of the second bearing member is provided with a concave sliding surface 36. The sliding surface 36 is spherical - see the arrow marked with R - incorporated into the axial end of the second bearing member 24. The second bearing member is further provided with a recess in the form of a central through-bore 38. The diameter of the through hole 38 is indicated by the reference D ₃₈ . D ₃₆ denotes the outer diameter of the concave-spherical sliding surface 36. The thickness of the flange 30 is designated by the reference symbol W30. The flange 30 is provided at both outer edges with a chamfer 40.

In the following, the first bearing member will be explained in detail with reference to the illustration of FIGS. 8-10.

As best seen in Fig. 8, the first bearing member 22 is as shown here Embodiment essentially of 4 areas, namely a threaded area 40, a base region 42, a Gleitflächenbereich 44 with more sliding surface 46th and a pin projection 48.

The free axial side of the threaded portion 40, as shown in Fig. 9, has a Tool engagement area in the form of a Inbusöffnung 50 on. The outer circumference of the Threaded portion 40 is complementary to the internal thread 26 external thread 52, see also the reference M 52.

The sliding surface 46 is formed as a convex spherical sliding surface. It has the same radius R as the sliding surface 36. The diameter D _{46 of} the convex sliding surface 46 is dimensioned larger than the diameter D _36th The pin projection 48 protrudes centrally from the sliding surface 46 in the axial direction. It has a diameter D ₄₈ , which is smaller than the diameter D ₃₈ .

The function of the door hinge 2 according to the first embodiment described here will be explained in more detail in the following with reference to the illustration of FIG. If not yet attached Cover button 28, the Inbusöffnung 50 can be reached by means of an Allen key. This allows the first bearing member via the threaded engagement of the threads 26, 52 in the axial Direction are shifted. Fig. 19 shows an example arrangement of the door hinges 2 on a door 60, which has a door leaf 62 and a frame 64. During installation This door is first the door hinge 2 in disassembled state to the individual door elements 64, 62 attached. And that is not yet connected to the frame part 6 Wing part 4 by means of the wing strap 14 attached to the door leaf 62, z. B. welded. The not yet connected to the wing part 4 frame part 6 is by means of Frame band 16 welded to the frame 64. In the still isolated band elements 4, 6 can be clamped on the free ends of the tube sleeve 11, the second bearing member 24 become. The first bearing members 22 are screwed into the tube sleeves 10 in such a way that they are completely inside the tube sleeves 10. In this condition the frame 64 and the door leaf 62 are individually supplied to the paint. For this the frame 64 is suspended with the tube sleeve 10 to a Lackiergehänge (not shown). The door leaf 62 is connected to the tube sleeve 11 to a Lackiergehänge (not shown) hung, with the Lackiergehänge passed through the central passage bore 38 becomes. The painting can be done easily because the adjustable first bearing member 22 is protected inside the tube sleeve 10.

Only after painting the door leaf 62 and the frame 64 are brought together. In this case, the tube sleeve 11 is executed between the two tube sleeves 10, wherein the respective axes are arranged concentrically, as shown in the figures. After that the first bearing elements 22 by turning over Allen key the second Bearing members 24 approximated until the pin projection 48 in the central through hole engages and the two sliding surfaces 46 and 36 detect, as in Fig. 3rd is shown.

The adjustment of the first bearing members 22 can then by inserting a (not shown) plastic knob are limited in the tube sleeves 10, as this will be explained below with reference to the fourth embodiment. The plastic button is located then later according to the illustration of Fig. 3 between the first bearing member 22 and the cover button 28 within the tube sleeve 10 and limits the adjustment the first bearing member 22, so that this can not be turned back so far, that it would lose its positive engagement with the second bearing member 24. The plastic plug still leaves a certain adjustment of the respective first Bearing member 22 in the manner described below. To such an afterthought To enable adjustment, is the plastic plug to be used with a provided central axial passage opening, passed through an Allen key and can be inserted into the socket opening 50.

The axial length L _{11 of} the tube sleeve 11 is dimensioned so short that it still leaves an overall play 54 between the two tube sleeves 10 at both boundary points 18 even when the two flanges 30 rest on the tube sleeve 11, which results in an overall length L ₃₀ . By moving the two first bearing members 22 in one of the axial directions in the same direction, the wing part 4 can be moved axially relative to the frame part 6 to adjust the door leaf 62 axially relative to the frame 64, as indicated by the arrows 56 in FIG is. The plastic plug for limiting the adjustment of the first bearing members 22 is clamped during assembly of the door 60 at such a distance from the first bearing member 22 within the tube sleeve 10 that the post-adjustment described above is still possible.

After adjustment, the cover buttons 28 for optical reasons on the free ends of the tube sleeves 10 placed.

A second embodiment of a door hinge is shown in FIGS. 11-18, wherein for corresponding parts, the same reference numerals used in the first embodiment have been. The second embodiment is different from the first embodiment essentially in that the adjustable first bearing member is not the Band element limbs, but the first band element received therebetween, here the wing part 4, is assigned. This second embodiment is less preferred since the first bearing member 22 only after painting just before assembly the door parts 64, 62 can be used.

The second bearing member 24 has the same construction as in the first embodiment. The Internal thread 26 is located here in the tube sleeve 11 of the wing part. 4

As is apparent from Figs. 15-18, the first bearing member 70 of the second embodiment formed differently from the first bearing member 22. Have in common the two bearing members 24, 70 a pin projection 48 and the convex spherical Sliding surface 46. Also, the threaded portion 40 is at the first bearing members 70 and 22 in essentially the same. However, in the first bearing member 70 is located between the threaded portion 40 and the sliding surface 46, a tool engagement portion 72 in Shape of a protruding flange with radial engagement openings 74. In the radial Engaging openings can be inserted pins, by means of which the first bearing member 70th rotatable and thus axially adjustable.

Except for the already mentioned fact that the assembly of the first bearing member 70th can only be done after painting if its adjustability is not due to paint coatings is to be affected, the function of the second embodiment is the same as described in the first embodiment. It will therefore be in full referred to the above statements.

The second band member may also be used instead of the one-piece embodiment shown in the figures be formed in several parts. So are in an embodiment not shown provided two second band members, each having a frame band for securing the Frame 24 and each having one of the two tube sleeves 10 shown in the figures. When mounting the second band elements they are at a suitable distance from each other welded to the frame, so that they between the tube sleeve 11 of the wing hinge part 4 record.

In the figures 20 - 23, a third embodiment of a door hinge is shown, wherein for corresponding parts the same reference numerals as in the first embodiment have been used. The third embodiment is different from the first one Embodiment only in that the frame band 16 with welding lugs 76th is provided.

In Figs. 24 - 27, a fourth embodiment of a door hinge 2 is still shown, wherein for corresponding parts, the same reference numerals as in the first embodiment have been used. The fourth embodiment is different from the first embodiment Embodiment essentially by the shape of the two bearing members 80, 90, the for receiving a sliding ring 88 are configured between them, as well as by a End cap 84, which with a longer, acting as an engagement region shaft portion 92 is formed. The end cap 84 thus acts as a stop for the first bearing member 80th and thus as Verstellwegbegrenzungseinrichtung 82nd

As the illustration in FIG. 26 shows, the sliding surfaces of the two bearing members 80, 90 each formed approximately perpendicular to the pivot axis 12, so that a simpler Sliding ring 88 can be used and the bearing members 80, 90 are easy to produce.

The pin projection 94 of the first bearing member 80 of the fourth embodiment is longer designed as the pin projection 48 of the first embodiment. The maximum game, the fully inserted pin projection 94 between the first bearing member 80th and the shaft portion 92 of the fully inserted end cap 84 has a smaller axial length than the pin projection 94. In this way limits the end cap 84 the displacement of the first bearing member 80 in the way that an unintentional Loosen the pin projection 94 from the recess, that is here the through hole 38 of the second bearing member 90, is prevented.

Characterized in that the end cap 84 only after the assembly of the two band elements 4, the sixth is used together, as can be seen from the exploded view of Fig. 24 is, the Verstellwegbegrenzungseinrichtung 82 only after the introduction of the pin projection 94 is placed in the through hole 38 in function.

The end cap 84 still has a through opening 98 in its end face 96 which a tool can be passed. Through the passage opening 98 can an Allen key to the Imbusöffnung 50 are guided to the door hinge 2 also at fully installed door 60 height adjustable.

FIGS. 28 to 31 show a fifth embodiment of a door hinge, wherein for corresponding parts, the same reference numerals as in previously explained embodiments are used. Again, each slide bearing 20 in the direction of Swivel axis 12 axially adjustable first bearing member 100 and a second bearing member 102 on. In the fifth embodiment, the first bearing member 100 is respectively in the tube sleeves 10 each band element leg 8 used. This is the inside of the tube sleeves 10 provided with the internal thread 26. The outer ends of the tube sleeves 10 are each closed by the cover button 28. The second bearing members 24 each Slide bearing 20 also close cover button similar to the two ends of the tube sleeve 11 of the wing part from.

The second bearing member 102 has approximately a hat-shaped shape with the flange 30 and the insert 32. The insert 32 is used for insertion into the tube sleeve 11, 10 a the band elements 4, 6. He has an outer diameter of a few hundredths of a millimeter larger than the inner diameter of the tube sleeves 10, 11, to firmly clamped therein to become. To facilitate the introduction, the free end of the insert part 32 be provided with a chamfer of about 15 °. The flange 30 serves to rest on the axial end of the tube sleeve 10, 11 and has an outer diameter which is approximately the Outer diameter of the tube sleeve 10, 11 corresponds. The axial provided with the flange 30 End of the second bearing member 102 is provided with a flat sliding surface 106. The second bearing member 102 is further with a recess in the form of a central Through hole 108 provided.

The first bearing member 100 has an approximately cylindrical shape in the fifth embodiment Threaded portion 110 and a pin projection 112. The pin projection 112 is here also cylindrical with a smaller diameter than the threaded portion 110 is formed and protrudes from one end of the threaded portion 110. At the so between the Spigot projection 112 and the threaded portion 110 formed step is a flat Sliding surface 114 is formed. The free axial side of the threaded portion 110, the Pin projection 112 is opposite, has a tool engagement area in the form the Allen 50 opening. The outer circumference of the threaded portion 110 is connected to the the internal thread 26 complementary external thread 52 is provided.

Compared with the previously described embodiments, the one shown here differs Embodiment on the one hand by the flat sliding surfaces 106, 114, a easier manufacturability of the bearing members 100, 102 and thereby significantly reduced Costs bring with these pronounced mass products. The other is the pin projection 112 longer than the axial extent of the through hole 108th educated. This has the advantage that even with larger adjustment of the first bearing member 100 of the pin projection 112 securely engages in the through hole and as Pintle used for the rotary movement of the door.

The fifth embodiment of the door hinge 2 further comprises a locking device 116 for the first bearing member 100. The locking device 116 prevents unwanted adjustment of the first bearing member 100. In the example shown here is the locking device an anti-rotation device to prevent unwanted rotation of the first bearing member. Such a twist could be caused by too strong a frictional attack caused on the sliding bearing 20, for example, in dirt, aging phenomena or the like in or on the sliding bearing 20. The locking device 116 has in the here example shown a grub screw 120, when screwed into a threaded hole 122, the first bearing member 100 sets.
