Description

The invention relates to a door hinge according to the preamble of the appended claim 1, as is known from DE 24 12 725 A1.

The invention further relates to a door provided with such a hinge, in particular Fire protection door, and method for assembling and manufacturing such a door.

DE 24 12 725 A1 mentioned at the outset describes a door hinge for the pivotable mounting a door on a frame. The hinge has a hinge element to be attached to the door and a hinge element to be attached to the frame. A first of these two Band elements is overlapped by the second band element in a U-like manner, i. H. the first Band element is inserted between two band element legs of the second band element. There is a predetermined axial movement between the two band elements available. The band elements are connected to one another via ball bearings as bearing means pivotally connected. One of the two bearing elements, which have a ball as a rolling element are stored together, is axially adjustable like a grub screw. So trained Ball bearings are provided at both boundary points between the band elements.

This known design creates a door hinge that can be easily adjusted leaves to adjust the door leaf vertically in relation to the frame. This allows the familiar Belt system an infinitely variable height adjustment for on-site adjustment.

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

Disadvantages of the known door hinges are their relatively complex structure, the necessity a relatively complex assembly of the hinge on the door leaf and / or the frame and the associated relatively complex assembly of such known hinge systems provided door.

Starting from the prior art according to DE 24 12 725 A1, it is an object of the invention maintaining a door hinge according to the preamble of appended claim 1 to design its advantages cheaper and easier to assemble. This Object is achieved by a door hinge with the features of appended claim 1.

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 manufacturing processes this is the subject of further independent claims.

The door hinge according to the invention has a first hinge element and at least a second Band element, which is compared to the first band element about a pivot axis is pivotable. Bearing means are provided between the two band elements. The first band element is with intermediate storage of the bearing means between two band element legs of the second band element recordable. In an alternative embodiment According to the invention, two second band elements are provided, between which the first Band element is recordable.

The bearing means have a first bearing element on one of the band elements, which is adjustable is positionable. The first band element is preferably pivotable axis parallel direction adjustable. A second bearing member is then on the other Band element provided.

By adjusting the first bearing member, the two bearing members of the Plain bearing can be directly engaged or disengaged.

To accomplish the intervention, it is preferably provided that one of the two Bearing members has a projecting pin projection in the direction of the pivot axis. The other of the two bearing members has a recess for receiving the pin projection Mistake. By axial adjustment of the bearing member is the pin projection more or less engageable with the recess.

Instead of roller bearings, a plain bearing is preferably provided between the band elements. The plain bearing has the first bearing member and that directly or indirectly on it sliding second bearing member. By using a plain bearing additional rolling elements that are difficult to place can be avoided. This requires a significant simplification of the structure of the storage means. But at the same time assembly of the door hinge itself and the door provided with the door hinge is also facilitated, since no additional rolling elements have to be inserted during assembly. This is particularly interesting with the adjustable bearing element because of the adjustability of the first bearing member not only an adjustment of the door leaf to the frame can be accomplished is.

An advantageous embodiment of the invention enables extensive pre-assembly of the hinge on the door. This advantageous embodiment is characterized by this from that the pin projection has such an axial extension and arranged in such a way and is designed such that the two band elements with bearing members preassembled thereon purely pivotally connected to each other via adjustment of the first bearing member or can be removed from each other. With accordingly deferred The first bearing element 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 position used can be the axial projection of the first bearing member of the pin projection in the Insert recess. As a result, the band elements are in their pivotable engagement brought together.

Based on the above teaching, it will be clear to the person skilled in the art that such a masking of the pin projection can be accomplished in a variety of ways. Please note the interplay of the adjustability of the first bearing element and the play of movement between the band elements.

For example, the pin projection could protrude with an axial length that is equal to or less than the play between the band elements to be fastened together. This movement play is defined by the difference between the distance of the two band element legs of the second band element or alternatively the distance between the two band elements on the one hand and the extension of the first Band element in the swivel axis direction on the other hand. With this training the Pin projection also present on the second, possibly non-adjustable, bearing member his.

It could also be provided that the pin projection projects with an axial length, which is smaller than the axial displacement of the first bearing member.

The pin projection could, however, also have a greater length than the corresponding one Project bearing link. The spigot should be advantageous for the functioning Design not only by the axial adjustability of the first bearing member can be brought from the detection with the recess, but also the way to remove release the belt elements with bearing elements pre-assembled on them.

The term "tenon protrusion" is also not based on any shapes, such as a cylindrical shape, limited. The protruding spigot could also be variously different Shapes, for example a cone shape, an ellipse shape, a hemisphere shape or have the like. To ensure the swiveling, however, are rotationally symmetrical Formations of the pin and the recess are preferred.

In order to adjust the height of the first band element relative to the second To accomplish a band element over a larger path is preferred if at everyone of the two boundary points between the first and second belt element with a plain bearing adjustable first bearing member is provided. By 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 secure in their respective Recesses remain in place. For inserting the first band element the first bearing members of the two plain bearings are then adjusted towards each other. And the first two are used to adjust the band elements axially relative to one another Bearing elements adjusted in the same direction to each other.

To prevent incorrect operation at the construction site or in the event of subsequent adjustment can avoid, according to a preferred embodiment, a limiting device the adjustment path of the first bearing member can be provided. This facility is attached to each other after the assembly of the two hinge elements or set that resetting the first bearing member in such a way that this the positive engagement between the two bearing members is canceled, avoidable is. In a specific embodiment, the two wall elements could be installed a plastic plug or a plug element on one the first Bearing member detecting thread may be provided. This is preferably done in such a way that the first bearing member can still be moved to adjust the vertical alignment of the door, however, it cannot be adjusted to such an extent that the positive engagement is canceled becomes.

The adjustable first bearing member is preferably provided with the pin projection. So can be taken out of the way by resetting the bearing member of the pin projection in order to articulate or remove the band elements from one another.

The sliding surfaces of the bearing members preferably engage in each other. For this it is preferred 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.

The pin projection could also be provided on the concave surface above his. The bearing members are easier to manufacture if 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 that 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 have tapered sliding surfaces exhibit. Elliptical shapes would also be conceivable.

Preferably, because it is relatively easy to manufacture, flat sliding surfaces are provided, in particular with a sliding ring, or spherically shaped sliding surfaces. With a spherically shaped one Sliding surface can also be an inclination of one of the band elements accomplish or handle relative to the pivot axis.

If the two band elements are formed with approximately concentric to the pivot axis Pipe sleeves are provided, as is the case in the prior art and for many users The door hinge according to the invention can be used with those already in use Manufacture wall elements for this without major changes in the production process.

As already fundamentally from the closest prior art according to DE 24 12 725 A1 known, the adjustability of the first bearing member is preferably thereby realizes that the band element to be provided with this is a concentric to the Has pivot axis formed axial opening with an internal thread, while the first bearing member has a correspondingly complementary external thread. The first bearing link is preferably formed like a grub screw. Is preferably on one of the sliding surface facing away from the axial side a tool engagement device is provided. The first bearing link could be designed in the manner of an Allen screw. This design has the advantage that the first bearing member is completely in the axial opening of the band element can be turned back. With such a completely pivoted bearing element the band element can still be painted even in the pre-assembled state. In particular it can also be powder coated. The one pre-assembled inside the band element The 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 end provided with the sliding surface and the threaded shaft then a tool engagement area, for example a hexagon, is provided. Prefers the tool engagement area is provided with several radial openings into which a pin can be inserted, by means of which the bearing member can be rotated.

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

Special features can also be used to facilitate or enable the plain bearing properties Surface coatings or the like can be provided on the sliding surfaces. easily usual lubricants are used. It is also possible to use one Sliding intermediate ring made of plastic, such as. B. Teflon or the like.

To the reliability and operational safety of a door hinge according to the invention provided to further improve the door, it is further preferred that the adjustable first Bearing member is associated with a locking device with which the position of the first bearing member can be secured. For example, this can be a locking screw in the form a grub screw or the like. The locking device is the first Bearing member prevented from relocating. It is thus excluded that unintentional relocation of the first bearing member an unwanted lowering or lifting of the door leaf provided with the door hinge or even the pin projection from the detection with the recess. Fixing is especially with one by rotating adjustable first bearing member advantageous. Such twisting could inadvertently occur during operation of the door due to excessive frictional engagement on the slide bearing. This could cause the bearing element to move out of position and the opening and the locking function or the attachment of the door leaf to the frame.

The locking device on the one hand maintains the position once set. To the others can not the pin projection by unwanted displacement of the first bearing member get out of its detection in the recess, so that a rotation limitation, as is provided in an embodiment of the invention is unnecessary. Finally, the pin projection can engage deeper in the recess; possibly one resulting increase in friction leads to the locking device not to an unwanted rotation or other displacement of the first bearing member.

A door provided with a door hinge according to the invention, in which the one hinge element is attached to the door leaf and the other hinge element on the frame easy installation with simultaneous adjustability of the door leaf and frame out.

A first embodiment of a door hinge 2 is described below with reference to FIGS. 1-4 explained in more detail. The door hinge 2 has a first hinge element in the form of a door leaf Wing part 4 to be fastened and a second band element in the form of a to Frame to be fastened to frame part 6. As from the representation of FIGS. 1 and 4 easily visible, the frame part 6 is substantially U-shaped and encompasses with two band element legs 8, the wing part 4. Both band element legs 8 and the wing part 4 each have an essentially cylindrical tubular sleeve 10, 11 on, the axis of symmetry essentially with the later pivot axis 12 of the Door hinge 2 coincides. A wing hinge 14 is on the tubular sleeve 11 of the wing part 4 attached to a door leaf. The band element legs 8 are by a Frame hinge 16 connected, which is to be attached to the frame. At the border points 18 between the tubular sleeve 11 of the wing part 4 and the two tubular sleeves 10 of the frame part 6, bearing means are provided in the form of a slide bearing 20 each.

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

The second bearing member 24 has an approximately hat-shaped shape with a flange 30 and an insert part 32. The insert part 32 serves for insertion into the tubular sleeve 11, 10 of one of the band elements 4, 6. It has an outer diameter D ₃₂ which is 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 insertion, the free end of the insert 32 is provided with a chamfer of approximately 15 °. The flange 30 is used 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 of the second bearing member provided with the flange 30 is provided with a concave sliding surface 36. The sliding surface 36 is spherical - see the arrow marked 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 hole 38. The diameter of the through hole 38 is indicated by the reference symbol D ₃₈ . D ₃₆ denotes the outer diameter of the concave-spherical sliding surface 36. The thickness of the flange 30 is identified by the reference symbol W30. The flange 30 is provided with a chamfer 40 on both outer edges.

The first bearing element is explained in more detail below with the aid of the illustration in FIGS. 8-10.

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

The free axial side of the threaded area 40, as shown in FIG. 9, has one Tool engagement area in the form of an Allen opening 50. The outer circumference of the Thread area 40 is with an external thread complementary to the internal thread 26 52 provided, see also the reference number M 52.

The sliding surface 46 is designed 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 larger than the diameter D ₃₆ . The pin projection 48 protrudes centrally from the sliding surface 46 in the axial direction. It has a diameter D ₄₈ that is smaller than the diameter D ₃₈ .

The function of the door hinge 2 according to the first embodiment described here is explained in more detail below with reference to the representation of FIG. 3. When not yet on Cover button 28, the Allen opening 50 can be reached by means of an Allen key. As a result, the first bearing member can be engaged axially via the thread engagement of the threads 26, 52 Direction to be shifted. 19 shows an example of an 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 the disassembled state on the individual door elements 64, 62 attached. And that is not yet connected to the frame part 6 Wing part 4 fastened to the door leaf 62 by means of the wing hinge 14, e.g. B. welded. The frame part 6 not yet connected to the wing part 4 is by means of the Frame hinge 16 welded to the frame 64. With the still singular band elements 4, 6, the second bearing member 24 can be clamped onto the free ends of the tubular sleeve 11 become. The first bearing members 22 are screwed into the tube sleeves 10 in such a way that that they are completely inside the tube sleeves 10. In this condition the frame 64 and the door leaf 62 are each supplied individually for painting. For this the frame 64 with the tubular sleeve 10 is hung on a painting hanger (not shown). The door leaf 62 is attached to a paint hanger (not shown) with the tubular sleeve 11. suspended, the paint hanger being guided through the central through bore 38 becomes. Painting can be done easily because of the adjustable first bearing element 22 is protected inside the tubular sleeve 10.

Only after painting the door leaf 62 and the frame 64 are brought together. The tube sleeve 11 is carried out between the two tube sleeves 10, the respective axes are arranged concentrically, as shown in the figures. After that the first bearing elements 22 become the second by turning them with an Allen key Bearing members 24 approximated until the pin projection 48 in the central through hole engages and grips the two sliding surfaces 46 and 36, as shown in FIG. 3 is shown.

The adjustment of the first bearing members 22 can then be done by inserting a Plastic button (not shown) in the tube sleeves 10 are limited, as this is explained further below using the fourth embodiment. The plastic button is located then later as shown in FIG. 3 between the first bearing member 22 and the cover button 28 within the tubular sleeve 10 and limits the adjustment path of the first bearing member 22, so that it cannot be turned back so far, that it would lose its positive engagement with the second bearing member 24. However, the plastic plug still leaves some adjustment of the first one Bearing member 22 in the manner described below. To such a retrospective To enable adjustment, the plastic stopper to be used with a provided central axial through opening through which an Allen key is passed and can be inserted into the Allen opening 50.

The axial length L _{11 of} the tubular sleeve 11 is dimensioned so short that even when the two flanges 30 rest on the tubular sleeve 11, which results in a total length L _{30, there} is still a total play 54 between the two tubular sleeves 10 at both limit points 18. By moving the two first bearing members 22 in the same direction in one of the axial directions, the wing part 4 can be moved axially relative to the frame part 6 in order to adjust the door leaf 62 axially relative to the frame 64, as indicated by the arrows 56 in FIG. 19 is. The plastic stopper for limiting the adjustment path of the first bearing members 22 is clamped within the tubular sleeve 10 at such a distance from the first bearing member 22 during assembly of the door 60 that the subsequent adjustment described above is still possible.

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

11-18, a second embodiment of a door hinge is shown, wherein the same reference numerals are used for corresponding parts in the first embodiment have been. The second embodiment differs from the first embodiment essentially in that the adjustable first bearing member is not the Band element legs, but the first band element received between them, 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 structure as in the first embodiment. The Internal thread 26 is located here in the tubular sleeve 11 of the wing part 4.

15-18, the first bearing member 70 is the second embodiment different from the first bearing member 22. Have together the two bearing members 24, 70 a pin projection 48 and the convex spherical Sliding surface 46. The thread area 40 is also in the first bearing members 70 and 22 in trained essentially the same.
