EP3359763B1 - Hinge for a folding flap - Google Patents

Description

The invention relates to a hinge for connecting two partial flaps of a folding flap, with a first and a second articulated part, which are articulatedly connected to one another, an articulated axis connected to the first articulated part being rotatably mounted in a detent position in a guide arranged on the second articulated part and in one disengaged position is guided displaceably along a guide region of the guide and the first joint part can be connected to a partial flap via a first mounting element and the second joint part via a second mounting element.

From the EP 1 727 954 B1 a hinge with two hinge parts for connecting two partial flaps of a folding flap is known, as is used, for example, for closing cupboards. When closed, the partial flaps lie in one plane, while they are open at an angle to one another in order to expose the interior of the cabinet. The hinge parts are connected to mounting plates which are attached to the partial flaps. At least one joint part is slidably mounted on a mounting plate, being held in a first position by a force-exerting holding device. If the holding force is overcome, the joint part can move from the first position to a second position.

While the partial flaps can be closed regularly in the first position, they are spaced apart in the second position of the displaceable joint part, so that an enlarged gap is formed between the partial flaps. This can prevent, for example, a finger from being pinched between the partial flaps of the folding flap. The disadvantage here is that the joint part is slidably mounted on a rigid mounting plate which is connected directly to a partial flap. This results in a rigid, non-resilient connection, which, even with a slight misalignment between the components of the hinge, can lead to the force required to overcome the holding force being clearly above the desired force at which an injury can be excluded. Another disadvantage is the alignment of the guide, in which the joint part is moved from the first to the second position. This is not or not adapted over the entire sequence of movements when the folding flap is closed to the direction of the force which is caused by a jammed object. As a result, the joint part can get caught, which blocks the displacement.

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

The EP 1 505 238 B1 discloses a hinge for the articulated connection of two folding elements of a folding flap or folding door. The hinge consists of one with the first folding element connected support arm to which a first hinge arm is articulated via a first hinge axis. Opposite, a second hinge arm is articulated 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 to the support arm via a snap-in connection. During the regular opening and closing of the folding flap, the first and the second swivel arm lie against the support arm, while the fastening part swings about the second hinge axis. If, for example, a finger is pinched between the folding elements when the folding flap is closed, the latching connection between the second hinge arm and the support arm is released. As a result, the articulated connection formed from the first and the second hinge arm opens up, so that the gap between the folding elements is also enlarged here, thereby preventing the finger from being pinched. The US 6,557,959 B1 discloses a hinge according to the preamble of claim 1.

A disadvantage of the arrangements disclosed in the prior art is that the force which, for example in the case of a pinched finger, acts on the latching and release mechanisms provided does not work optimally in the direction of an intended release direction of the respective mechanism. As a result, it can happen that the release only takes place when there is an increased force or, in the worst case, not at all, so that a residual risk of an injury remains.

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

The object of the invention is achieved in that the guiding direction of the guide, starting from the latching position, changes continuously or discontinuously against the direction of rotation of the second joint part when the hinge closes. Following the locking position, the guide can advantageously be oriented such that it points in the direction of the acting force when a finger is pinched. As a result, the locking connection is reliably triggered at a defined force and the joint axis is released from the locking position into the guide. When the folding door is closed further, the orientation of the guide changes such that the guide direction continues to point in the direction of the force acting through the pinched finger. This measure prevents the orientation of the guide and the force acting in different directions when the folding flap is closed with the finger pinched and the associated rotation of the second joint part. It is thus possible to reliably prevent the articulated axis from snagging in the guide, so that no high forces act on the pinched finger even after the latching connection has been triggered, and the gap between the partial flaps of the folding flap is easily and sufficiently enlarged. In the case of a continuous change in the guide direction of the guide, this can have, for example, a circular curve or some other arc shape. In the case of a discontinuous change, several linear sections of the guide arranged at an angle to one another can follow one another.

Optimal alignment of the guide to the forces caused by a pinched finger or other object can be achieved in that the guide direction of the guide in the area of the latching position is oriented at an acute angle to a mounting surface of the second mounting element and that the angle between the guide direction the guide and the mounting surface of the second mounting element is continuously or discontinuously reduced with increasing distance from the locking position.

In this case, smooth guidance of the joint axis over the entire length of the guide can be ensured by the guide direction of the guide in the area of the locking position at an angle between 30 ° and 60 °, preferably between 40 ° and 50 °, with respect to the mounting surface of the second mounting element is aligned and / or that the guide direction of the guide in its area opposite the latching position is oriented at an angle between + 20 ° and -20 °, preferably between + 10 ° and 0 °, with respect to the mounting surface of the second mounting element.

A simple locking of the joint axis in the locking position is achieved in that the cross section of the guide between the locking position and the guide area is rejuvenated. Such a taper can be achieved, for example, by lugs arranged on one or both sides of the guide, which hold the articulated axis in the latching position. If a certain force acting on the hinge axis is exceeded in the direction of the guide, it is pulled past the attachment (s) into the guide area of the guide, within which it can then be moved easily. The lugs preferably have bevels on one or both sides. This results in a constant release force of the joint axis from the locking position. It also makes it easier to snap the joint axis into place.

The hinge can be manufactured inexpensively in that the first joint part is connected in one piece to the first mounting element and / or in that the second joint part is connected in one piece to the second mounting element. Due to the one-piece construction, no additional connecting elements between the joint parts and the respective assembly elements are required, as a result of which both the manufacturing costs and the assembly costs can be reduced.

According to a preferred embodiment variant of the invention, it can be provided that the second joint part has a second joint arm, into which the guide is formed in a holding section opposite the second mounting element, and that the joint arm is designed to be resilient with respect to the second mounting element. The articulated arm is thus fixed to the partial flap in the region of the mounting element, while the opposite section is arranged freely and thus resiliently. Minor misalignments between the joint parts can be compensated for by the resilient articulated arm. This reliably prevents the joint axis from tilting in the guide, so that it can be moved in the guide in an easily movable manner. Furthermore, the resilient articulated arm has a dampening effect on the opening and closing process of the folding flap.

A good spring effect of the second joint part can be achieved in that the cross section of the second joint arm is tapered, at least in sections. The spring action can be adapted to the respective requirements through the selected taper.

A good spring action as well as a secure locking of the joint axis in the locking position can be achieved in that the second joint part is made of an elastic material, in particular of plastic.

It can preferably be provided that the first articulated part has a first articulated arm and that in the closed position of the hinge the first articulated arm is guided from the first mounting element past the second mounting element to the guide of the second articulated 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 facing away from the gap. The first articulated arm preferably spans the second articulated arm up to its end, at 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 locking position. Furthermore, the articulated arms enable the slightly resilient connection between the two partial flaps.

If it is provided that the first assembly element has at least one elongated hole and that the first assembly element can be connected to the first partial flap in an adjustable manner along the longitudinal extent of the elongated hole by means of at least one assembly screw, the two partial flaps can be mounted in the direction of the longitudinal extent of the elongated hole when the folded flap is assembled can be adjusted to each other. With a corresponding arrangement of the one or more elongated holes, the two partial flaps can be set, for example, transversely to one another, or the gap between the two partial flaps can be set.

It can preferably be provided that the position of the first joint part relative to the first mounting element can be adjusted 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 extension allows the gap width between the partial flaps to be adjusted. An adjustment transversely to the longitudinal extent of the first joint part, on the other hand, enables the Align partial flaps laterally to each other or to align the plate levels or the inclination of the partial flaps to each other.

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, in that a first part of the first mounting element is connected to the first joint part, and in that a second part of the first mounting element is connected to the first partial flap is connectable and that the position of the first part of the first assembly element relative to the position of the second part can be adjusted 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 partial flaps can thus be precisely aligned with one another by adjusting the relative position between the two parts of the first mounting element. In addition, it is possible for the position of the first joint part to be adjustable in relation to the first mounting element. With such an arrangement, many setting options can be provided.

It can preferably be provided that at least one eccentric and / or a worm drive and / or an adjusting screw and / or a clamp connection is provided as the adjusting means. The setting means can act between the first joint part and the first mounting element or between the two parts of the first mounting element.

A simple alignment and fixing of the first joint part with respect to the first assembly element can be achieved in that the first assembly element facing the first joint part has a corrugated surface with grooves running transversely or longitudinally to the longitudinal extent of the first joint part and in that the first joint part has a corresponding corrugated second Has surface which engages in the corrugated surface of the first mounting element when the hinge is mounted. The first joint part can thus be aligned with the first mounting element without mutual engagement of the corrugated surfaces. Then the corrugated surfaces are put together and pressed together, for example by a clamping screw. Because of that Formed fit between the corrugated surfaces, the position of the first joint part relative to the first mounting element is fixed. The gap width between the two partial flaps can be set, for example, by corrugated surfaces with grooves running transversely to the longitudinal extent of the first joint part. Longitudinal grooves, on the other hand, allow the lateral alignment of the two partial flaps to one another.

Figure 1 shows a top 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 with a first mounting element 50. For this purpose, the first mounting element 50 has laterally arranged first fastening flanges 51, which are pierced by elongated holes 51.1. Assembly screws 21 are guided through these and screwed to the first partial flaps 11. Second fastening flanges 61 are arranged on the second mounting element 60. Bores 61. 1 are made in these through which the second mounting element 60 is screwed to the second partial flap 12 by means of mounting screws 21.

A first joint part 30 of the hinge 20 is fastened to the first mounting element 50. In the present exemplary embodiment, the first joint part 30 and the first mounting element 50 are made in one piece. The first articulated part 30 has a first articulated arm 31 which, via a gap 13 separating the two partial flaps 11, 12, forms an in Figure 2 shown second articulated arm 41 of a second articulated part 40 is guided. 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.

In the present exemplary embodiment, the second joint part 40 is connected in one piece to the second mounting element 60. At its end facing away 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 connected to one another in an articulated manner via a joint axis 22. The hinge axis 22 is arranged between the fastening section 31.2 of the first hinge part 30 and the holding section 41.3 of the second hinge part 40.

The folding flap 10 is not shown connected to further hinge elements attached to the first partial flaps 11, for example to a body of a cabinet. The folding flap 10 closes the interior of the cabinet. To the When the cabinet is opened, the first partial flap 11 is pivoted about these hinge elements. The hinge 20 opens and the two partial flaps 11, 12 fold together about the axis of rotation 22, as shown in FIG Figure 3 is shown.

In the exemplary embodiment shown, elongated holes 51. 1 are made in the first fastening flanges 51 of the first mounting element 50 in the direction of the axis of rotation 22. The elongated holes 51.1 enable the two partial flaps 11, 12 to be aligned laterally with respect to one another before the mounting screws 21 are firmly tightened.

Figure 2 shows in a side sectional view that in Figure 1 Hinge 20 shown with the folding flap 10 closed. The cut is made along the line shown in FIG Figure 1 shown and marked with II cutting line.

The first articulated part 30, starting from the first assembly element 50, engages with its first articulated arm 31 around the second articulated arm 41 of the second articulated part 40. The second articulated part 40 has spaced-apart side webs 41.1, as clearly shown in FIG Figure 5 is shown. In the area of the second articulated arm 41, troughs 41.2 are formed in the side webs 41.1, as a result of which the cross section of the articulated arm 41 is tapered in this area. Subsequent to the troughs 41.2, the second articulated arm 41 ends with the holding section 41.3. A guide 42 is introduced as a breakthrough in the holding section 41.3 with the laterally adjacent side webs 41.1. On the end of the guide 42 facing away from the second mounting element 60, a latching position 42.1 is arranged, in which the hinge axis 22 is rotatably mounted. A guide area 42.2 of the guide 42 adjoins the detent position 42.1. In the present exemplary embodiment, the guide area 42.2 is formed by two linear guide sections 42.6, 42.7, which are arranged continuously and at an angle to one another. Finally, the guide area 42.2 ends at a stop 42.5.

The two spaced-apart side webs 41.1 are connected to a connecting web which is continuous in the present exemplary embodiment. The holding section 41.3 as part of the connecting web is followed by a central web 41.4 and then a Floor bridge 41.6. The connecting web in the area of the center web 41.4 changes from the side of the side webs 41.1 facing away from the second partial flap 12, on which the holding section 41.3 is arranged, to the side of the side webs 41.1 facing the second partial flap 12, where the bottom web 41.6 is located. The connecting web thus runs approximately S-shaped in the region of the second articulated arm 41. Below the holding section 41.3 is formed by a recess 41.5.

The second mounting element 60 lies against the surface of the second partial flap 12 with a mounting surface 62. Starting from the second mounting element 60, the second articulated arm 41 is guided at a distance along the surface of the second partial flap 12.

In Figure 3 is that in the Figures 1 and 2 shown hinge 20 shown in a side sectional view with the folding flap 10 open.

The first articulated arm 31 of the first articulated part 30 is connected with the articulated axis 22 to the second articulated arm 41 of the second articulated part 40. For this purpose, the first articulated arm 31 has an articulated bore 31.3 on each side in its fastening section 31.2. The hinge axis 22 is inserted through the hinge bores 31.3 and the locking position 42.1 of the guide 42. The first and second articulated arms 31, 41 are thus connected to one another in an articulated manner.

In the in Figure 3 Open position of the folding flap 10 shown, the first partial flaps 11 and the second partial flap 12 are pivoted relative to one another about the hinge axis 22. For closing, the second partial flap 12 with the second joint part 40 is pivoted about the joint axis 22 in accordance with the closing direction 29 symbolized by an arrow. Accordingly, the first partial flap 11 with the first joint part 30 is rotated about the joint axis 22 counter to the closing direction 29 of the second partial flap 12. After completion of the closing process, the partial flaps 11, 12 are again in the in the Figures 1 and 2 shown closed position before.

During a regular opening or closing process, the articulated axis 22 remains held in the latching position 42.1 of the guide 42. As a result, the gap 13 is again present with the set gap width when the folding flap 10 is closed.

Figure 4 shows in a side view that in the Figures 1 to 3 The hinge 20 shown with the folding flap 10 partially open and a finger 14 clamped between the partial flaps 11, 12. The articulated axis 22 is disengaged from its locking position 42.1 and moved along the guide 42 up to its stop 42.5. As a result, the gap 13 formed between the partial flaps 11, 12 is enlarged to such an extent that there is no longer any risk of injury for the pinched finger 14.

In Figure 4 the position of the partial flaps 11, 12 is shown at the end or shortly before the end of a closing movement with a pinched object, for example the finger 14 shown or a hand. The second guide section 42.7 of the guide area 42.2 facing the gap 13 points in the direction of the gap 13 and the pinched finger 14.

The guide direction of the guide area 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 area 42.2, it bends into the second linear guide section 42.7. The second linear guide section 42.6 of the guide area 42.2 is oriented approximately in the direction of the mounting surface 62. The guiding direction of the guiding area 42.2 thus changes with increasing distance from the latching position 42.1 against the direction of rotation (closing direction 29) of the second joint part 40 during a closing movement. In the exemplary embodiment shown, the direction of change is discontinuous between the first and second linear guide sections 42.6, 42.7 of the guide area 42.2.

In the Figure 4 shown arrangement of the partial flaps 11, 12 and the hinge parts 30, 40, starting from the in Figure 3 shown open state of the folding flap 10, reached when the folding flap 10 is closed. Starting from Figure 3 will be the first Partial flap 11 against the illustrated closing direction 29 and the second partial flap 12 pivoted in the direction of the shown closing direction 29 about the hinge axis 22. Here, intermediate positions, not shown, between the in Figure 3 and Figure 4 through the positions shown. If an object is clamped between the partial flaps 11, 12 in one of the intermediate positions during the closing movement, a force is transmitted to the two joint parts 30, 40. Due to the alignment of the guide area 42.2 in direct connection to the latching position 42.1 (first guide section 42.6), the direction of the force and the guide direction of the guide area 42.2 are aligned approximately the same. Forces acting transversely to the guide direction are largely avoided. As a result, the articulated axis 22 is disengaged from its detent position 42.1 with a defined force and is displaced along the first guide section 42.6 into the second guide section 42.7 without the articulated axis 22 getting caught in the guide 42. When the second partial flap 12 and the second joint part 40 connected therewith move further, the guide 42 also rotates in the direction of the closing direction 29 shown. As a result, the second guide section 42.7 of the guide region 42 is optimally aligned with the force acting. The joint axis 22 can thus be moved smoothly and without getting caught in the second guide section 42.7 of the guide 42 even when the second partial flap 12 is rotated further in the closing direction 29.

Due to the different alignment of the two guide sections 42.6, 42.7, it is thus achieved that the joint axis 22 can be released from the latching position 42.1 with a predetermined force acting between the partial flaps 11, 12 and can be moved easily and without jamming along the guide 42. The stop 42.5 of the guide 42 is arranged such that a sufficiently large gap 13 is formed between the partial flaps 11, 12, so that a risk of injury from a pinched finger 14 can be excluded.

Figure 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 connected in one piece to the second mounting element 60. The side webs 41.1 are spaced apart. The side webs 41.1 are connected to one another by the connecting web. The connecting web is on one side of the second joint part 40 through the second mounting element 60 and subsequently through the in FIG Figure 2 shown floor bridge 41.6. Starting from the bottom web 41.6, the center web 41.4 runs to the holding section 41.3. The guide 42 with the latching position 42.1 and the guide area 42.2 is formed in the holding section 41.3. The hinge axis 22 is rotatably fixed in the locking position 42.1. For this purpose, the guide 42 is tapered by an extension 42.3 following the locking position 42.1. The approach 42.3 has a run-up slope 42.4 towards the locking position 42.1. The second joint part 40 is preferably made of an elastic material, in particular of plastic. If a force acts on the hinge axis 22 in a guide direction of the guide 42 predetermined by the orientation of the first guide section 42.6, the hinge axis 22 passes from the latching position 42.1 into the first guide section 42.6 and from there into the second guide section 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 area of the second articulated arm 41, the side webs 41.1 are tapered by the depressions 41.2. Due to the construction of the second articulated arm 41 with the regionally tapered side webs 41.1, the approximately S-shaped connecting web and the elastic material used, the second articulated arm 41 can move resiliently with respect to the second mounting element 60. On the one hand, this has a damping effect on the opening and closing process of the folding flap 10. Furthermore, slight misalignments between the two joint parts 30, 40 can be compensated for, so that any jamming of the joint axis 22 caused thereby when it is adjusted within the guide 42 can be avoided.

Figure 6 shows a hinge 20 accordingly Figure 1 with an additional column setting. For this purpose, the first joint part 30 and the first mounting element 50 are made in two parts and are connected to one another by means of two retaining bolts 33.1, 33.2 and a clamping screw 23 arranged in a longitudinal guide 32, as is explained in more detail to Figure 7 is described. By loosening the clamping screw 23, the first joint part 30 can be displaced along the longitudinal guide 32 with respect to the first mounting element 50 and the gap width of the gap 13 between the partial flaps 11, 12 can thereby be set. The lateral alignment of the two partial flaps 11, 12 takes place, as already described, via the two elongated holes 51.1 arranged in the first fastening flanges 51.

Figure 7 shows the first mounting element 50 of FIG Figure 6 shown hinge 20 in a possible embodiment. A cuboid-shaped holding attachment 52 is arranged between the two fastening flanges 51 and connected in one piece to the fastening flanges 51. The holding attachment 52 is broken through by a linear opening 52.1. The two retaining bolts 33.1, 33.2 are held in a linearly movable manner in the linear opening 52.1. Set the retaining bolts 33.1, 33.2 as in Figure 6 shown, the connection between the first mounting element 50 and the first joint part 30. On the side of the holding attachment 52 facing away from the first partial flap 11, the holding attachment 52 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 holding attachment 52.

This in Figure 6 The first joint part 30 shown has a corrugated surface corresponding to the corrugated surface 53. When the clamping screw 23 is not tightened, the first joint part 30 and the first mounting element 50 can be displaced relative to one another along the longitudinal guide 32 and the gap width can thereby be set. 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. As a result, the position of the first joint part 30 relative to the first mounting element 50 and thus the gap width is determined.

Figure 8 shows a perspective side view of a hinge 20 accordingly Figure 6 in another arrangement for column adjustment. The linear displacement of the first joint part 30 with respect to the first mounting element 50 takes place by actuating an in Figure 9 shown worm drive 24. The worm drive 24 can be actuated via a tool attachment 24.2, which is accessible via an opening 35 introduced into the front of the second joint part 40. The lateral alignment of the two partial flaps 11, 12 takes place via the two elongated holes 51.1 arranged in the first fastening flanges 51
In Figure 9 is that in Figure 7 First mounting element 50 shown shown in an embodiment with the worm drive 24. A screw receptacle 54 is formed on the side of the holding attachment 52 facing away from the first partial flap 11. The screw seat 54 is closed by a front and a rear screw bearing 54.1, 54.2. A worm 24.1 is partially let into the worm receptacle 54 and rotatably supported in the worm bearings 54.1, 54.2 with a front and a rear bearing section 24.3, 24.4. When the first joint part 40 is installed, the worm 24.1 engages in a helical toothing attached to the first joint part 40. By rotating the screw 24.1 via the tool attachment 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 partial flaps 11, 12 can be adjusted. The worm drive 24 advantageously enables the width of the gap 13 to be continuously adjusted.

Figure 10 shows a top view of a hinge 20 with a longitudinal, transverse and inclination adjustment of the partial flaps 11, 12. The longitudinal adjustment allows adjustment of the gap width, while the transverse adjustment enables the mutual lateral alignment of the two partial flaps 11, 12. The inclination of the two partial flaps 11, 12 can be aligned with one another by the inclination setting. The first joint part 30 has a front and a rear opening 34.1, 34.2 on its upper side. A gap adjustment eccentric 26 is rotatably mounted in the front opening 34.1. The rear opening 34.2 has an internal thread into which an inclination adjustment screw 27 can be screwed.

How especially out Figure 11 can be seen, the first mounting element 50 is constructed in two parts. A pin 28 guided in a linear guide 55 oriented transversely to the longitudinal extent of the first joint part 30 represents a linearly displaceable connection between the two parts of the first mounting element 50. The two parts can be aligned along the alignment with the aid of a first eccentric 25 the linear guide 55 are mutually displaced. This results in the lateral alignment of the two partial flaps 11, 12.

Figure 11 put that in Figure 10 shown hinge 10 in a perspective view from below and thus from the side of the partial flaps 11, 12 which are hidden in the illustration. The first fastening flanges 51 are connected in one piece to a holding projection 56 and thus form an upper part 58 of the first mounting element 50. The holding projection 56 has a U-shaped profile. In the side legs of the retaining lug 56, bolt guides 56.1 are introduced as elongated holes. 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 element 50 within the bolt guides 56.1 in a linearly displaceable manner.

The in Figure 10 The gap adjustment eccentric 26 shown engages with an eccentrically arranged pin (not shown) in an elongated hole (likewise not shown) on the holding projection 56. By rotating the gap adjusting eccentric 26, the first joint part 30 can thus be displaced in the direction of its longitudinal extent with respect to the first mounting element 50 and the gap width can thus be set. The also in Figure 10 Tilt adjustment screw 27 shown is rotatable, but axially blocked fixed on the retaining lug 56. The inclination of the partial flaps 11, 12 can be adjusted by screwing the inclination adjustment screw 27 in or out of the rear opening 34.2.

How especially out Figure 11 can be seen, a mounting base 57 is arranged as a separate component of the first mounting element 50 in a cavity encompassed by the first fastening flanges 51 and the area arranged between them. In this case, a central section 57.1 of the basic assembly body 57 is arranged opposite the holder projection 56. Side sections 57.2, 57.3, which laterally adjoin the center section 57.1, each extend under the first fastening flanges 51. A middle bracket 57.6 is formed on the center section 57.1. This is hooked between the legs of the holding projection 56 on the upper part 58 of the first mounting element 50. On the side sections 57.2, 57.3 are also molded bracket 57.7, 57.8. These engage in guide slots 51.2, which are introduced into the side walls of the first fastening flanges 51. The in Figure 10 The pin 28 shown is fixed to the first side section 57.2 in a bore 57.4 attached to it. An eccentric pin 25.1 connected to the first extender 25 is linearly displaceable and axially blocked and held in an elongated hole 57.5 made in the second side section 57.3 of the mounting base body 57. The upper part 58 of the first mounting element can thus be moved laterally to the longitudinal extent of the first joint part 40 and is connected to the basic assembly body 57 in a blocked manner 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 partial flap 11. The mounting base body 57 itself is fixed on the first partial flap 11 via the mounting screws 21. By rotating the first eccentric 25, the engagement of the first eccentric pin 25.1 in the elongated hole 57.5 of the mounting base 57 causes the upper part 58 and the associated first joint part 40 to be displaced relative to the mounting base 57 transversely to the longitudinal extent of the first joint part 40. The two partial flaps 11, 12 can thus be laterally aligned with one another.
