Abstract

The invention relates to a hinge (20) for connecting two sub-flaps (11, 12) of a folding flap (10), comprising a first and a second joint part (30, 40) which are connected together in an articulated manner. A joint axis (22) connected to the first joint part (30) is mounted in a guide (42) arranged on the second joint part (40) in a rotatable manner in a latched position (42.1) and is guided in a movable manner along a guide region (42.2) of the guide (42) in a non-latched position. The first joint part (30) and the second joint part (40) can be connected to a respective sub-flap (11, 12) via a first mounting element (50) and a second mounting element (60), respectively. Starting from the latched position (42.1), the guide direction of the guide (42) changes continuously or discontinuously opposite the rotational direction of the second joint part (40) during a closing movement of the hinge (20). The hinge (20) substantially reduces the risk of injury due to clamping a finger between the two sub-flaps (11, 12).

Description

Hinge for a folding flap

The invention relates to a hinge for connecting two partial flaps of a folding flap, with a first and a second hinge part, which are hinged together, wherein a hinge axis connected to the first hinge part rotatably mounted in a arranged on the second hinge part guide in a latching position and in a in the disengaged position along a guide region of the guide is displaceably guided and wherein the first joint part via a first mounting member and the second joint part via a second mounting member, each having a partial flap are connectable.

From EP 1 727 954 B1 a hinge with two joint parts for connecting two partial flaps of a folding flap is known, as used for example for closing cabinets. Closed, the partial flaps lie in one plane, while they are open at an angle to each other to release the cabinet interior. The hinge parts are connected to mounting plates, which are attached to the partial flaps. At least one joint part is displaceably mounted on a mounting plate, wherein it is held by a force-applying holding device in a first position. If the holding force is overcome, the joint part can move from the first position to a second position. While in the first position, the partial flaps can be closed regularly, they are arranged at a distance in the second position of the displaceable hinge part, so that an enlarged gap between the partial flaps is formed. This can be avoided that, for example, a finger is trapped between the partial flaps of the folding flap. The disadvantage here is that the hinge part is slidably mounted on a rigid mounting plate which is directly connected to a partial flap. This results in a rigid, non-resilient connection, which can lead even at a low misalignment between the components of the hinge to the fact that the force required to overcome the holding force is well above the desired force at which injury can be ruled out. Another disadvantage is the orientation of the guide, in which the hinge part is moved from the first to the second position. This is not or not adapted to the direction of the force, which is caused by a clamped object, during the entire sequence of movement when closing the folding flap. This can cause the hinge part to get caught, which blocks the movement.

EP 1 308 591 B1 likewise describes a hinge for a folding flap with a first and a second folding element. A fastening element is fastened with a first fastening surface on a first folding element. On the fastening element, a first arm of the hinge is pivotally mounted about a first pivot axis. A second arm is hinged to the first arm. Opposite, the second arm has a fastening means with which it is attached to the second folding element. To open and close the folding flap, the second arm is pivoted about the hinged connections to the first arm. The first arm is held in position. If, during closing, an object is clamped between the two folding elements, then the first arm releases against a holding force and pivots about the first pivot axis into a second position. As a result, the gap between the two folding elements is increased, so that no finger between the folding elements can be clamped.

EP 1 505 238 B1 discloses a hinge for hingedly connecting two folding elements of a folding flap or folding door. The hinge consists of one with the first Falteiement connected support arm to which a first hinge axis, a first hinge arm is articulated. Opposite, a second hinge arm is hingedly connected to the first hinge arm via a third hinge axis. The second hinge arm is in turn connected via a second hinge axis to a fastening part, which is fastened to the second folding element. The second hinge arm is connected via a latching connection with the support arm. Thus, during the regular opening and closing of the folder, the first and second pivot arms rest against the support arm while the attachment portion oscillates about the second hinge axis. If, for example, a finger is clamped between the folding elements when closing the folding flap, then the locking connection between the second hinge arm and the support arm is released. As a result, the articulated joint formed by the first and the second hinge arm folds up, so that here too the gap between the folding elements is increased, thereby preventing pinching of the finger.

A disadvantage acts in the arrangements disclosed in the prior art, the force which acts, for example, in a pinched finger on the provided locking and release mechanisms, not optimal in the direction of an intended release direction of the respective mechanism. As a result, it may happen that the release does not occur at all under an increased force or in the worst case, so that a residual risk for an injury remains.

It is an object of the invention to provide a hinge for a folding flap with a pinch protection, which safely triggers when needed.

The object of the invention is achieved in that the guide direction of the guide, starting from the locking position, against the direction of rotation of the second joint part during a closing movement of the hinge changes continuously or discontinuously. The guide can advantageously be aligned following the locking position so that it points at a pinched finger in the direction of the acting force. As a result, the latching connection is reliably released at a defined force and the articulated axle is released from the latching position into the guide. ben. Upon further closure of the folding door, the orientation of the guide changes such that the guiding direction continues to point in the direction of the force acting on the pinched finger. By this measure it is avoided that when closing the folding flap with a trapped finger and the associated rotation of the second joint part, the orientation of the guide and the force acting in different directions. A hooking of the hinge axis in the guide can be safely avoided, so that even after triggering the locking connection no high forces acting on the pinched finger and the gap between the partial flaps of the folding flap is smoothly and sufficiently increased. In a continuous change of the guide direction of the guide, this may for example have a circular curve or another arc shape. In the case of a discontinuous change, a plurality of linear sections of the guide arranged at an angle to each other can follow one another.

Optimal alignment of the guide to the forces caused by a pinched finger or other object can be achieved by aligning the guiding direction of the guide in the region of the locking position at an acute angle to a mounting surface of the second mounting element and by adjusting the angle between the guiding direction the guide and the mounting surface of the second mounting member decreases continuously with increasing distance to the locking position or discontinuously.

In this case, a smooth running guide the hinge axis over the entire length of the guide can be ensured that the guide direction of the guide in the locking position at an angle between 30 ° and 60 °, preferably between 40 ° and 50 °, relative to the mounting surface of the second mounting member is aligned and / or that the guide direction of the guide in its the latching position opposite region is aligned at an angle between + 20 ° and -20 °, preferably between + 10 ° and 0 °, relative to the mounting surface of the second mounting element.

A simple locking of the hinge axis in the latching position can be achieved in that the cross section of the guide between the latching position and the guide is rejuvenated. Such a taper can for example be achieved by one or both sides of the guide arranged approaches that hold the hinge axis in the locking position. If a certain force acting on the joint axis is exceeded in the direction of the guide, then it is pulled past the projection (s) into the guide region of the guide, within which it can then be moved smoothly. Preferably, the approaches have on one or both sides run-on slopes. Through this, a constant release force of the hinge axis is achieved from the detent position. Furthermore, the engagement of the hinge axis is facilitated.

The hinge can be produced inexpensively that the first hinge part is integrally connected to the first mounting member and / or that the second hinge part is integrally connected to the second mounting member. Due to the one-piece construction, no additional connecting elements between the joint parts and the respective mounting elements are required, whereby both the manufacturing costs and the assembly costs can be reduced.

According to a preferred embodiment of the invention, it may be provided that the second joint part has a second articulated arm, in which the guide is formed in a holding section opposite the second mounting element, and in that the articulated arm is resilient with respect to the second mounting element. The articulated arm is thus fixed in the region of the mounting member on the partial flap, while the opposite portion is free and thus resiliently arranged. The resilient articulated arm low misalignments between the joint parts can be compensated. As a result, a tilting of the hinge axis in the guide is reliably avoided, so that it can be moved easily movable in the guide. Furthermore, the resilient articulated arm dampens the opening and closing operation of the folding flap.

A good spring action of the second joint part can be achieved in that the cross section of the second articulated arm is at least partially tapered. Due to the selected taper, the spring action can be adapted to the respective requirements. A good spring action as well as a secure locking of the hinge axis in the latching position can be achieved in that the second hinge part is made of an elastic material, in particular of plastic.

Preferably, it can be provided that the first joint part has a first articulated arm and that the first articulated arm is guided in the closed position of the hinge from the first mounting element on the second mounting element over to the guide of the second joint part. When the folding flap is closed, the first articulated arm bridges the gap between the two partial flaps. Starting from the second mounting element, the second articulated arm points in the direction away from the gap. The first articulated arm preferably spans the second articulated arm up to its end, on which the latching position of the guide is then arranged. The articulated arms arranged in this way enable the desired folding movement of the two partial flaps about the articulated axis mounted in the detent position. Furthermore, the articulated arms allow the slightly resilient connection between the two partial flaps.

If it is provided that the first mounting element has at least one oblong hole and that the first mounting element can be connected to the first partial flap by means of at least one mounting screw along the longitudinal extent of the oblong hole, the two partial flaps can be used in the direction of the longitudinal extension of the oblong hole during assembly of the folding flap adjusted to each other. With an appropriate arrangement of the slots or the two partial flaps, for example, be set transversely to each other or it can be adjusted, the gap between the two partial flaps.

It can preferably be provided that the position of the first joint part relative to the first mounting element is adjustable by means of adjusting means in the direction of the longitudinal extent of the first joint part and / or transversely to the longitudinal extent of the first joint part. The adjustment in the direction of the longitudinal extent allows adjustment of the gap width between the partial flaps. An adjustment transversely to the longitudinal extent of the first joint part, however, allows the Align partial flaps laterally to one another or to align the plate planes or the inclination of the partial flaps to one another.

An exact mutual adjustment of the positions of the first and the second partial flap can be achieved in that the first mounting element is designed in two parts, that a first part of the first mounting member is connected to the first hinge part, that a second part of the first mounting member with the first partial flap is connectable and that the position of the first part of the first mounting member relative to the position of the second part by means of adjusting means in the direction of the longitudinal extent of the first hinge part and / or is adjustable transversely to the longitudinal extent of the first joint part. The partial flaps can thus be aligned by adjusting the relative position between the two parts of the first mounting element exactly to each other. In addition, it is possible that the position of the first joint part relative to the first mounting member is made adjustable. Such an arrangement can provide many adjustment possibilities.

Preferably, it can be provided that at least one eccentric and / or a worm drive and / or an adjusting screw and / or a clamping connection is provided as adjusting means. The adjusting means may act between the first hinge part and the first mounting member or between the two parts of the first mounting member.

A simple alignment and fixing of the first joint part with respect to the first mounting element can be achieved by the first mounting element facing the first joint part having a corrugated surface with grooves running transversely or longitudinally to the longitudinal extent of the first joint part and the first joint part corrugating a second one corresponding thereto Surface which engages with mounted hinge in the corrugated surface of the first mounting member. The first joint part can thus be aligned initially without mutual engagement of the corrugated surfaces with respect to the first mounting element. Subsequently, the corrugated surfaces are juxtaposed and compressed, for example by a clamping screw. By the way formed positive connection between the corrugated surfaces, the position of the first joint part relative to the first mounting member is fixed. For example, the gap width between the two partial flaps can be adjusted by corrugated surfaces with grooves running transversely to the longitudinal extent of the first joint part. However, longitudinal grooves allow the lateral orientation of the two partial flaps to each other.

Fig. 11, the hinge shown in Figure 10 in a perspective view from below. FIG. 1 shows a plan view of a folding flap 10 with two partial flaps 11, 12 and a hinge 20 connecting the partial flaps 11, 12. The hinge 20 is connected to the first partial flap 11 by a first mounting element 50. For this purpose, the first mounting member 50 laterally arranged on the first mounting flanges 51, which are pierced by slots 51.1. Through this mounting screws 21 are guided and bolted to the first part flaps 11. On the second mounting member 60 second mounting flanges 61 are arranged. In these holes 61.1 are introduced, through which the second mounting member 60 is screwed by means of mounting screws 21 to the second part of the flap 12.

On the first mounting member 50, a first hinge part 30 of the hinge 20 is attached. In the present embodiment, the first joint part 30 and the first mounting member 50 are made in one piece. The first joint part 30 has a first articulated arm 31, which is guided over a gap 13 separating the two partial flaps 11, 12 to a second articulated arm 41 of a second joint part 40 shown in FIG. The first joint part 30 has a U-shaped profile with which it engages around the second joint part 40 when the hinge 20 is closed. At its end opposite the first mounting element 50, the first joint part 30 has a fastening section 31.2 into which a recess 31.1 is made.

The second joint part 40 is integrally connected in the present embodiment with the second mounting member 60. At its end remote from the second mounting element 60, a holding section 41.3 is arranged. The first joint part 30 and the second joint part 40 are hingedly connected to each other via a hinge axis 22. Here, the hinge axis 22 between the mounting portion 31.2 of the first joint part 30 and the holding portion 41.3 of the second joint part 40 is arranged.

The folding flap 10 is not shown connected to other attached to the first part flaps 11 hinge elements, for example, with a carcass of a cabinet. The folding flap 10 closes the interior of the cabinet. To the Opening the cabinet, the first part flap 11 is pivoted about these hinge elements. In this case, the hinge 20 opens and the two partial flaps 11, 12 fold around the axis of rotation 22 to each other, as shown in Figure 3.

In the embodiment shown in the first mounting flanges 51 of the first mounting member 50 in the direction of the axis of rotation 22 extending slots 51.1 are introduced. The slots 51.1 allow lateral alignment of the two partial flaps 11, 12 to each other before the mounting screws 21 are tightened.

FIG. 2 shows a side sectional view of the hinge 20 shown in FIG. 1 with the folding flap 10 closed. The cut is made along the section line shown in FIG. 1 and marked II.

The first joint part 30 emanating from the first mounting element 50 engages with its first joint arm 31 the second joint arm 41 of the second joint part 40. The second joint part 40 has spaced-apart side webs 41. 1, as clearly shown in FIG. In the region of the second articulated arm 41, depressions 41.2 are formed in the side webs 41.1, whereby the cross section of the articulated arm 41 is tapered in this area. Subsequently, the second articulated arm 41 ends with the holding portion 41.3 to the hollows 41.2. In the holding portion 41.3 with the laterally adjacent side webs 41.1 a guide 42 is introduced as a breakthrough. On the second mounting member 60 remote from the end of the guide 42, a locking position 42.1 is arranged, in which the hinge axis 22 is rotatably mounted. The locking position 42.1 is followed by a guide region 42.2 of the guide 42. The guide portion 42.2 is formed in the present embodiment by two linear guide portions 42.6, 42.7, which are arranged continuously and at an angle to each other. Finally, the guide portion 42.2 ends at a stop 42.5.

The two spaced side webs 41.1 are connected to a continuous connecting web in the present embodiment. The holding section 41.3 as part of the connecting web is followed by a middle web 41.4 and subsequently a Footbridge 41.6. In the process, the connecting web in the region of the center web 41.4 changes from the side of the side webs 41.1 facing away from the second part flap 12, on which the holding section 41.3 is arranged, to the side web 41.1 facing the second part flap 12, where the bottom web 41.6 is located. The connecting web thus extends in the region of the second articulated arm 41 in an approximately S shape. Below the holding portion 41.3 is formed by a recess 41.5.

The second mounting member 60 abuts with a mounting surface 62 on the surface of the second partial flap 12. The second articulated arm 41, starting from the second mounting element 60, is guided at a distance along the surface of the second partial flap 12.

In FIG. 3, the hinge 20 shown in FIGS. 1 and 2 is shown in a side sectional view when the folding flap 10 is open.

The first articulated arm 31 of the first articulated part 30 is connected to the articulation axis 22 with the second articulated arm 41 of the second articulated part 40. For this purpose, the first articulated arm 31 in its attachment portion 31.2 on each side each have a joint bore 31.3. The hinge axis 22 is inserted through the hinge holes 31.3 and the locking position 42.1 of the guide 42. Thus, the first and the second articulated arm 31, 41 are hinged together.

In the open position of the folding flap 10 shown in FIG. 3, the first partial flaps 11 and the second partial flap 12 are pivoted about the hinge axis 22 relative to one another. For closing, the second partial flap 12 is pivoted about the hinge axis 22 with the second hinge part 40 in accordance with the closing direction 29 symbolized by an arrow. Accordingly, the first partial flap 11 is rotated with the first hinge part 30 against the closing direction 29 of the second partial flap 12 about the hinge axis 22. After completion of the closing operation, the partial flaps 11, 12 are again in the closed position shown in Figures 1 and 2. In a regular opening or closing operation, the hinge axis 22 remains in the latching position 42.1 of the guide 42 is held. As a result, the gap 13 is again in the closed folding flap 10 with the set gap width.

FIG. 4 shows in a side view the hinge 20 shown in FIGS. 1 to 3 with partially opened folding flap 10 and a finger 14 clamped between the partial flaps 11, 12. The hinge axis 22 is disengaged from its latching position 42.1 and along the guide 42 until it stops 42.5 postponed. As a result, the gap 13 formed between the partial flaps 11, 12 is increased to the extent that there is no longer any danger of injury to the pinched finger 14.

FIG. 4 shows the position of the partial flaps 11, 12 at the end or shortly before the end of a closing movement with a clamped object, for example the finger 14 or a hand shown. Here, the gap 13 facing the second guide portion 42.7 of the guide portion 42.2 in the direction of the gap 13 and the pinched finger 14th

The guide direction of the guide region 42.2 of the guide 42 is aligned at an acute angle to the mounting surface 62 of the second mounting element 60 in direct connection to the latching position 42.1 (first guide section 42.6). After the first linear guide section 42.6 of the guide region 42.2, this bends off into the second linear guide section 42.7. In this case, the second linear guide section 42.6 of the guide region 42.2 is aligned approximately in the direction of the mounting surface 62. The guide direction of the guide portion 42.2 thus changes with increasing distance from the locking position 42.1 against the direction of rotation (closing direction 29) of the second joint part 40 during a closing movement. In this case, the change in the guide direction in the illustrated exemplary embodiment occurs discontinuously between the first and the second linear guide section 42.6, 42.7 of the guide region 42.2.

The arrangement of the partial flaps 11, 12 and the hinge parts 30, 40 shown in FIG. 4 is achieved when closing the folding flap 10, starting from the opened state of the folding flap 10 shown in FIG. Starting from Figure 3, the first Partial flap 11 against the illustrated closing direction 29 and the second partial flap 12 pivoted in the direction of the illustrated closing direction 29 about the hinge axis 22. In this case, not shown intermediate positions between the positions shown in Figure 3 and Figure 4 are traversed. If an object is clamped between the partial flaps 11, 12 during the closing movement in one of the intermediate positions, a force is transmitted to the two hinge parts 30, 40. As a result of the orientation of the guide region 42.2 immediately after the latching position 42.1 (first guide section 42.6), the direction of the force and the guide direction of the guide region 42.2 are aligned approximately the same. Forces acting transversely to the guide direction are largely avoided. As a result, the articulated axle 22 is disengaged from its latching position 42.1 with a defined force and displaced along the first guide section 42.6 into the second guide section 42.7, without the articulated axle 22 becoming caught in the guide 42. During the further rotational movement of the second partial flap 12 and the associated second hinge part 40, the guide 42 also rotates in the direction of the illustrated closing direction 29. As a result, the second guide section 42.7 of the guide region 42 is optimally aligned with the force acting. The hinge axis 22 can be moved smoothly and without getting caught in the second guide portion 42.7 of the guide 42 so even when further rotated in the closing direction 29 second part of the flap 12.

Due to the different orientation of the two guide portions 42.6, 42.7 is thus achieved that the hinge axis 22 with a predetermined force acting between the partial flaps 11, 12 force detached from the detent position 42.1 and smoothly and without jamming along the guide 42 can be moved. The stop 42.5 of the guide 42 is arranged so that a sufficiently large gap 13 between the partial flaps 11, 12 forms, so that a risk of injury can be excluded by a pinched finger 14.

FIG. 5 shows the second joint part 40 with the second mounting part 60 of the hinge 20 in a perspective side view. The two side webs 41. 1 of the second joint part 40 are integrally connected to the second mounting element 60. The side webs 41.1 are arranged at a distance. The side bars 41.1 are connected to each other by the connecting web. The connecting web is formed on one side of the second joint part 40 by the second mounting member 60 and subsequently by the bottom web 41.6 shown in FIG. Starting from the bottom web 41.6, the middle web 41.4 extends to the holding section 41.3. In the holding portion 41.3, the guide 42 is formed with the locking position 42.1 and the guide portion 42.2. The hinge axis 22 is rotatably fixed in the latching position 42.1. For this purpose, the guide 42 is tapered after the locking position 42.1 by a shoulder 42.3. The approach 42.3 has a stop bevel 42.4 towards the locking position 42.1. The second joint part 40 is preferably made of an elastic material, in particular of plastic. Acts on the hinge axis 22, a force in a predetermined by the orientation of the first guide portion 42.6 guide direction of the guide 42, the hinge axis 22 passes from the locking position 42.1 in the first guide portion 42.6 and from there into the second guide portion 42.7. In the second guide section 42.7, the guide direction is predetermined by the orientation of the second guide section 42.7.

In the region of the second articulated arm 41, the side webs 41.1 are tapered by the hollows 41.2. Due to the structure of the second articulated arm 41 with the partially tapered side bars 41.1, the approximately S-shaped connecting web and the elastic material used, the second articulated arm 41 can move resiliently relative to the second mounting member 60. In addition, slight misalignments between the two joint parts 30, 40 can be compensated for, so that thereby causing jamming of the joint axis 22 during its adjustment within the guide 42 can be avoided.

FIG. 6 shows a hinge 20 according to FIG. 1 with an additional gap setting. For this purpose, the first joint part 30 and the first mounting member 50 are made in two parts and connected by means of two retaining bolts 33.1, 33.2 and arranged in a longitudinal guide 32 clamping screw 23 together, as this closer to Figure 7 is described. By loosening the clamping screw 23, the first joint part 30 along the longitudinal guide 32 relative to the first mounting member 50 is displaced and thereby the gap width of the present between the part flaps 11, 12 gap 13 can be adjusted. The lateral alignment of the two partial flaps 11, 12 takes place, as already described, over the two elongated holes 51.1 arranged in the first fastening flanges 51.

FIG. 7 shows the first mounting element 50 of the hinge 20 shown in FIG. 6 in one possible embodiment. Between the two mounting flanges 51, a cuboid holding attachment 52 is arranged and integrally connected to the mounting flanges 51. The holding attachment 52 is interrupted by a linear opening 52.1. In the linear aperture 52.1, the two retaining bolts 33.1, 33.2 are held linearly movable. The retaining bolts 33.1, 33.2 provide, as shown in Figure 6, the connection between the first mounting member 50 and the first joint part 30 ago. On the side of the holding attachment 52 facing away from the first part flap 11, this has a corrugated surface 53. The grooves of the corrugated surface 53 are aligned along the gap 13. The clamping screw 23 is screwed into a corresponding threaded hole in the retaining attachment 52.

The first joint part 30 shown in FIG. 6 has a corrugated surface corresponding to the corrugated surface 53. When not tightening the clamping screw 23, the first joint part 30 and the first mounting member 50 along the longitudinal guide 32 against each other and thereby shifted the gap width can be adjusted. When the clamping screw 23 is tightened, the groove structure attached to the first joint part 30 engages in the grooves of the corrugated surface 53 of the holder attachment 52. Thereby, the position of the first joint part 30 relative to the first mounting member 50 and thus the gap width is determined.

FIG. 8 shows in a perspective side view a hinge 20 according to FIG. 6 in a further arrangement for gap adjustment. The linear displacement of the first joint part 30 relative to the first mounting member 50 is effected by actuation of a worm drive 24 shown in Figure 9. The worm drive 24 can be operated via a tool attachment 24.2, which is accessible via an end face in the second hinge part 40 introduced opening 35. The lateral alignment of the two partial flaps 11, 12 via the two arranged in the first mounting flanges 51 slots 51.1

FIG. 9 shows the first mounting element 50 shown in FIG. 7 in an embodiment with the worm drive 24. On the side facing away from the first part flap 11 side of the holding cap 52, a screw receptacle 54 is formed. The worm receptacle 54 is closed by a front and a rear worm bearing 54.1, 54.2. A worm 24.1 is partially embedded in the worm holder 54 and rotatably mounted with a front and a rear bearing portion 24.3, 24.4 in the screw bearings 54.1, 54.2. When mounted first joint part 40, the worm 24.1 engages in a mounted on the first joint part 40 helical gearing. By turning the worm 24.1 over the tool projection 24.2, the position of the first joint part 30 relative to the position of the first mounting element 50 and thus the gap width between the sub-flaps 11, 12 can be adjusted. Advantageously, the worm drive 24 allows a continuous adjustment of the width of the gap thirteenth

FIG. 10 shows a plan view of a hinge 20 with a longitudinal, transverse and tilt adjustment of the partial flaps 11, 12. The longitudinal adjustment thereby enables adjustment of the gap width, while the transverse adjustment enables the mutual lateral alignment of the two partial flaps 11, 12. By inclining the inclination of the two partial flaps 11, 12 are aligned with each other. The first joint part 30 has on its upper side on a front and a rear opening 34.1, 34.2. In the front opening 34.1 a Spaltinstellexzenter 26 is rotatably mounted. The rear opening 34.2 has an internal thread into which a tilt adjustment screw 27 can be screwed.

As can be seen in particular from FIG. 11, the first mounting element 50 is constructed in two parts. A guided in a transverse to the longitudinal extent of the first joint part 30 linear guide 55 guided pin 28 represents a linearly displaceable connection between the two parts of the first mounting member 50. The two parts can by means of a first eccentric 25 along the alignment tion of the linear guide 55 are mutually shifted. As a result, the lateral alignment of the two partial flaps 11, 12th

FIG. 11 shows the hinge 10 shown in FIG. 10 in a perspective view from below and thus from the side of the partial flaps 11, 12 hidden in the illustration. The first fastening flanges 51 are integrally connected to a holding lug 56 and thus form an upper part 58 of FIG first mounting member 50. The retaining lug 56 has a U-shaped profile. In the side legs of the retaining lug 56 designed as elongated holes bolt guides 56.1 are introduced. A retaining bolt 33 is inserted through corresponding bores in the first joint part 30 and through the bolt guides 56.1. The retaining bolt 33 connects the first joint part 30 and the upper part 58 of the first mounting member 50 within the pin guides 56.1 linearly displaceable.

The Spaltinstellexzenter 26 shown in Figure 10 engages with a not shown, eccentrically arranged pin in a likewise not shown slot on the holding lug 56 a. By turning the Spaltinstellexzenters 26 so the first hinge part 30 can be moved in the direction of its longitudinal extension relative to the first mounting member 50 and thus the gap width can be adjusted. The tilt adjustment screw 27, which is likewise shown in FIG. 10, is rotatable but axially blocked on the retaining extension 56. By inserting or unscrewing the inclination adjusting screw 27 in or out of the rear opening 34.2, the inclination of the partial flaps 11, 12 can be adjusted.

As can be seen in particular from FIG. 11, a mounting base body 57 is arranged as a separate component of the first mounting element 50 in a cavity enclosed by the first fastening flanges 51 and the region arranged therebetween. In this case, a center section 57.1 of the mounting base body 57 is arranged opposite to the holder lug 56. Side sections 57.2, 57.3 adjoining the middle section 57.1 laterally extend in each case under the first fastening flanges 51. An intermediate retaining angle 57.6 is integrally formed on the center section 57.1. This is hooked between the legs of the retaining lug 56 on the upper part 58 of the first mounting member 50. At the side sections 57.2, 57.3 are also brackets 57.7, 57.8 formed. These engage in guide slots 51.2, which are introduced into the side walls of the first mounting flanges 51. The pin 28 shown in Figure 10 is fixed to the first side portion 57.2 in a bore 57.4 attached thereto. A connected to the first extender 25 eccentric 25.1 is linearly displaceable and axially blocked held in a introduced in the second side portion 57.3 of the mounting base 57 slot 57.5. The upper part 58 of the first mounting element is thus displaceable laterally to the longitudinal extent of the first joint part 40 and in the direction of the longitudinal extent of the first joint part 40 and in the direction of the surface normal of the hidden first part flap 11 blocked connected to the mounting base body 57. The mounting base 57 itself is fixed on the mounting screws 21 on the first part flap 11. By turning the first eccentric 25 causes the engagement of the first eccentric pin 25.1 in the slot 57.5 of the mounting base 57, that the upper part 58 and the associated first joint part 40 is moved transversely to the longitudinal extent of the first joint part 40 relative to the mounting base 57. Thus, the two partial flaps 11, 12 can be aligned laterally against each other.
