DETAILED DESCRIPTION
[0120] Hinged closures 1 serve to lock a door leaf 10.1 with respect to a door frame 10.2 and to pivot the door leaf 10.1 with respect to the door frame 10.2, with the result that they have a dual function in this respect. A hinge assembly 11, which comprises multiple such hinged closures 11, consequently makes it possible to pivot and lock even the door leaves 10.1 of large doors 10 with respect to the door frame 10.2. Before the configuration of the hinge assembly 11 and its components are discussed in more detail below, firstly the underlying function of the hinged closures 1 arranged on a door leaf 10.1 are to be described in more detail.
[0121] The illustration of FIG. 1 depicts multiple doors 10 that are arranged closely next to one another, each having a door leaf 10.1 and a door frame 10.2. The door leaves 10.1 of the doors 10 are rectangular and in this respect are considerably taller than they are wide. Typically, such door arrangements are used for large servers or switching cabinets.
[0122] As can furthermore be seen in FIG. 1, each of the doors 10 shown has eight hinged closures 1 overall, with the result that each door leaf 10.1 can be pivoted and opened once to the left, that is to say about the respective four left-hand hinged closures 1, and similarly about the four right-hand hinged closures 1. In order to open the door leaf 10.1 to the left, it is then necessary to lock the left-hand hinged closures 1 and unlock the right-hand hinged closures 1. When the door leaf 10.1 is to be opened to the right, it is necessary to lock the right-hand hinged closures 1 and unlock the left-hand hinged closures 1. When all eight hinged closures 1 of a door 10 are locked, the door leaf 10.1 is held in place with respect to the door frame 10.2, and the door leaf 10.1 correspondingly cannot be moved. When all eight hinged closures 1 are unlocked, the door leaf 10.1 can be taken out of the door frame 10.2.
[0123] As can be seen in the illustration of FIG. 2, the hinged closures 1 of an end region of the door leaf 10.1, that is to say the right-hand hinged closures 1 and the left-hand hinged closures 1, are each arranged in a hinge bar 7. The hinge bar 7, together with the respective hinged closures 1, forms a hinge assembly 11, with the result that each of the door leaves 10.1 illustrated in FIG. 1 is connected to the door frame 10.2 via two hinge assemblies 11.
[0124] Before different configurations of and possible ways of mounting the hinge bars 7 or the hinge assemblies 11 are discussed in more detail below, now firstly the structure of the individual hinged closures 1 are to be described in more detail on the basis of FIGS. 5a and 5b. In the illustration of FIGS. 5a and 5b, a hinged closure 1 is shown in an exploded illustration. The hinged closures 1 that can be seen in FIGS. 1 and 2 correspond to those illustrated in FIGS. 5a and 5b.
[0125] The hinged closures 1 consist substantially of two parts, specifically a first hinge element 2 and a second hinge element 3. In the locking position V, the first hinge element 2 and the second hinge element 3 are pivotably connected to one another, with the result that the door leaf 10.1 can then be pivoted correspondingly about this hinged closure 1, or about the pivot axis S of the hinged closure 1. In terms of the hinge assembly 11 having multiple hinged closures 1, the hinge elements 2, 3 of each hinged closure 1 of a hinge assembly 11 are pivotable about the same pivot axis S, with the result that a pivot axis S can be assigned to each hinge assembly 11. Accordingly, all hinge elements 2, 3 of a hinge assembly 1 are pivotable relative to one another about the same pivot axis S. In the unlocking position E, the two hinge elements 2, 3 are then no longer pivotably coupled to one another, but are movable in translation relative to one another, with the result that the door leaf 10.1 then pivots correspondingly about another pivot axis S or the door leaf 10.1 can be taken out of the door frame 10.2, as was already described above.
[0126] The first hinge element 2 consists of three elements, specifically a hinge base 2.1, a latch 4 which can be moved back and forth in a latching direction R, and a latch holder 2.2. In this respect, the latch holder 2.2 and the hinge base 2.1 act as guides for the latch 4, and the latch 4 is received captively between these two elements, with the result that the latch 4 can only be removed when the hinge base 2.1 and the latch holder 2.2 are separated from one another. Both the hinge base 2.1 and the latch holder 2.2 have guides, which are denoted by 2.11 and 2.21, respectively, and in each of which a guide element 4.11 formed in the manner of a guide pin is guided. Upon a movement of the latch 4 in the latching direction R, the guide elements 4.11 then move in the corresponding guides 2.11, 2.21 and any other movement of the latch 4 is prevented. As can be seen in particular in FIG. 5b, the latch 4 has four guide pins overall, two of which are guided in the guide 2.11 of the hinge base 2.1 and two of which are guided in the guide 2.21 of the latch holder 2.2.
[0127] The latch holder 2.2 additionally also has a lateral guide for the latch 4, as can be seen in FIG. 5a. For this purpose, the latch sliding surface 2.22 is recessed, resulting in the production of a kind of receptacle having two lateral guide surfaces 2.23, which then laterally engage around and guide the latch 4.
[0128] As can also be seen, the latch 4 has a substantially L-shaped cross section, and it consists of a rather flat movement portion 4.1 and a latching portion 4.2 arranged perpendicularly thereto. The movement portion 4.1 is arranged between the hinge base 2.1 and the latch holder 2.2 and is moved back and forth between the locking position V and the unlocking position E by a drive rod 6.1, as will be described in more detail below on the basis of the further figures. The latching portion 4.2 has a block-shaped form and is therefore also considerably more stable than the movement portion 4.1. This is associated with the fact that, in the locking position V, the latching portion 4.2 ensures that the pivot pin 3.2 is received between the latching portion 4.2 and the hinge base 2.1, or the pivot pin receptacle 2.17 of the hinge base 2.1, and therefore is subject to comparatively high forces, this also being associated with the size, or the weight, of the door leaf 10.1.
[0129] Furthermore, the latching portion 4.2 has two recesses 4.21 which subdivide the latching portion 4.2 into three latching blocks 4.22. As can be seen on the basis of FIG. 5b, the hinge base 2.1 has two guide projections 2.15, which engage precisely in the recess 4.21 of the latching portion 4.2 and thus additionally serve to laterally guide the latching portion 4.2. Furthermore, the hinge base 2.1 also has additional lateral guide surfaces 2.14, which likewise laterally guide the latching portion 4.2.
[0130] The three-part division of the latching portion 4.2 is additionally also adapted to the configuration of the second hinge element 3, which is formed in the manner of a hinge block. As can be seen in FIG. 5b, the second hinge element 3 has a mounting region 3.1 with a planar surface, via which the second hinge element 3 can be connected to the door frame 10.2. The pivot pin 3.2, the longitudinal axis of which forms the pivot axis S of the hinged closure 1 and thus also the pivot axis of the door leaf 10.1 with respect to the door frame 10.2, is arranged spaced apart from this mounting region 3.1. The pivot pin 3.2 is connected to the mounting region 3.1 via a connecting region 3.3. The mounting region 3.1 has two stiffening ribs 3.31, which can be seen in FIG. 5b and are in line with the guide projections 2.15. In this respect, the three latching blocks 4.22 of the latch 4 engage around the two stiffening ribs 3.31 of the second hinge element 3 in the locking position V, and around the two guide projections 2.15 of the hinge base 2.1 in the unlocking position E. When moving between the locking position V and the unlocking position E, the latch 4, or the latching portion 4.2, consequently is moved either between the stiffening ribs 3.31, in order to secure the hinge pin 3.2 in the hinge pin receptacle 2.17, or between the guide projections 2.15, in order to release the hinge pin 3.2 in this unlocking position E.
[0131] To connect the hinge base 2.1 to the latch holder 2.2, the two elements have corresponding bores, with the result that the hinge base 2.1 can be connected to the latch holder 2.2 via a screw connection. The corresponding bores of the latch holder 2.2 are arranged on a connecting projection 2.24, and the bores of the hinge base 2.1 are arranged on a mounting portion 2.18, which likewise projects somewhat. A guide groove, which extends through the first hinge element 1 perpendicularly to the latching direction R and which also can be seen in FIG. 6a, is created behind the corresponding portions 2.18, 2.24 by these projections. In FIG. 6a, the latch 4 is not illustrated, but the intermediate space between the hinge base 2.1 and the latch holder 2.2, in which intermediate space the latch 4 is arranged, can be clearly seen. The corresponding surfaces of the intermediate space are each in the form of drive rod sliding surfaces and denoted by 2.16 and 2.25, respectively. The drive rod 6.1, which is also not illustrated in FIG. 6a and the functioning of which will be described in more detail below, is arranged in the groove-shaped intermediate space between the latch 4 and the hinge base 2.1 in the center region, or between the latch holder 2.2 and the hinge base 2.1 in the two outer regions.
[0132] The drive rod 6.1 is in the form of a flat rod and can be moved perpendicularly to the latching direction R and therefore in the longitudinal direction of the hinge bar 7. The drive rod 6.1 has four S-shaped guide slots 6.11 overall, each two of which are arranged in pairs and each two of which serve to drive a latch 4, with the result that two latches 4 can be moved back and forth by the drive rod 6.1. The guide elements 4.11 of the latch 4 that are guided in the guides 2.11, 2.21 of the latch base 2.1 are additionally also guided in the guide slots 6.11 of the drive rod 6.1. This is evident for example on the basis of FIG. 6a. The two guide elements 4.11 that face the hinge base 2.1 and are guided in the guides 2.11 specifically additionally penetrate the two guide slots 6.11 of the drive rod 6.1. In the process, each guide element 4.11 is guided in one of the guide slots 6.11. Upon a linear movement of the drive rod 6.1, the guide elements 4.11 then slide in the guide slots 6.11 and therefore move the latch 4 forward or back in the latching direction R, depending on the direction in which the drive rod 6.1 is moved.
[0133] In order to move the drive rod 6.1 correspondingly, a drive device 6.2 is provided which, together with the drive rod 6.1, forms an actuating device 6. The structure of the drive device 6.2 can be seen in the exploded illustration of FIG. 11. The drive device 6.2 first of all has a rotatable actuating element 6.24, which in the exemplary embodiment is in the form of tool actuation means, as can also be seen for example on the basis of FIG. 4 or FIG. 13a. As an alternative, however, the actuating element 6.24 may also be in the form of handle actuation means, knob actuation means, or pawl actuation means. The actuating element 6.24 is supported rotatably in the drive housing 6.25, and the drive housing 6.25 is connected to the hinge bar 7 via mounting points 7.6, which can be seen in FIG. 7a. The drive housing 6.25 likewise serves as a support for a pinion 6.22, which is rotationally coupled to the actuating element 6.24 and accordingly, upon a rotational movement of the actuating element 6.24, also moves correspondingly. The pinion 6.22 meshes with an actuating rod 6.23, which is in the form of a toothed rack and which has multiple recesses arranged next to one another, and, in the manner of a linear drive, has the effect that, when the pinion 6.22 is rotated, the actuating rod 6.23 moves correspondingly linearly in the longitudinal direction of the hinge bar 7. To guide the actuating rod 6.23, a linear guide 6.26 is provided, which likewise is connected to the drive housing 6.25 and therefore is not movable. The connection of the drive housing 6.25 and the linear guide 6.26 via two screws can also be seen in FIGS. 13a and 13b. Furthermore, it can be seen in particular in FIG. 13b that the actuating element 6.24 is secured in the axial direction via a screw so as to be able to rotate together with the pinion 6.22, and is connected to the drive housing 6.25 and to the linear guide 6.26.
[0134] At its two ends, the actuating rod 6.23 has hook-shaped connecting portions, via which it can be connected to two drive rods 6.1, that is to say to one on each side. When the actuating element 6.24 brings about the movement of the actuating rod 6.23, two drive rods 6.1 are consequently jointly set in motion. Since each drive rod 6.1 is coupled to two respective latches 4 via the guide slots 6.11 arranged in pairs, it is consequently possible for all four latches 4 of the hinge assembly 11 to be jointly moved in the same direction back and forth between the locking position V and the unlocking position E by the drive device 6.2. In one development, it would also be possible to also couple the drive rods 6.1 to further drive rods 6.1, in order thus also to actuate still more latches 4 at the same time.
[0135] FIGS. 12a and 12b show a blocking device 6.3, which is likewise part of the drive device 6.2. The blocking device 6.3 has a movable blocking tongue 6.31, which can be rotated back and forth in the manner of a casement lock. In the blocking position, the blocking tongue 6.31 engages in the recesses, which can be seen in FIG. 11, of the actuating rod 6.23 and then consequently prevents a movement of the actuating rod 6.23. As a result of the fact that the actuating rod 6.23 is coupled to the actuating element 6.24, by blocking the actuating rod 6.23, the actuating element 6.24 can then at the same time also no longer be rotated.
[0136] The blocking device 6.3 can be plugged into the drive housing 6.25 via a connecting region 6.32 and can be connected to the drive housing 6.25 by a screw. As can be seen on the basis of the various positions of the blocking device 6.3 in FIG. 4, the blocking device 6.3 may be arranged both below and above the drive housing 6.25. Accordingly, the drive housing 6.25 correspondingly also has two receptacles, into which the blocking device 6.3 can be plugged. The entire drive device 6.2, irrespective of whether a blocking device 6.3 is provided or not, may be in the form of a premounted mounting unit, which as a whole can be mounted on the hinge bar 7, as will be explained in more detail below on the basis of FIGS. 7a to 7f. This mounting unit can also be seen in FIGS. 13a, 13b.
[0137] As was already described above, the hinged closures 1, which are arranged in an end region of the door leaf 10.1, are mounted together on a hinge bar 7. This hinge assembly 11 is in the form of a premounted mounting unit and as a whole can be connected to the door leaf 10.1.
[0138] The figures show two different configurations of the hinge assembly 11, specifically one in FIGS. 1 to 4, which is a hinge assembly 11 connected to the inner side of the door leaf 10.1, with the result that the hinge bar 7 cannot be seen from the outside and is concealed between the door leaf 10.1 and the door frame 10.2. In another configuration, in which the hinge bar is arranged on the outer side of the door leaf 10.1, as illustrated for example in FIGS. 14 to 17, the hinge bar 7, or the hinge assembly 11, can be seen also from the outside. The hinge bar 7, or the hinge assemblies 11, of the two exemplary embodiments differ only slightly in terms of their design. Basically, it is therefore possible to premount a basic hinge bar which then, depending on whether it is to be used for internal mounting on the door leaf inner side or for external mounting on the door leaf outer side, can be adapted to the corresponding use case with only little effort. On the basis of FIGS. 7a to 7f and the sectional views of FIGS. 8 to 10, now first of all the internal mounting of the hinge assembly 11 will be described. The configuration of the hinge elements 2, 3 that was described in FIGS. 5a, 5b and 6, and the drive device 6.2, are basically usable both for internal mounting and for external mounting.
[0139] According to the illustration in FIG. 7a, the hinge bar 7 has a basic element 7.1, which rests on the surface of the door leaf 10.1 after mounting. A first limb element 7.2, which bears against a bent edge of the door leaf 10.1 in the case of internal mounting of the hinge bar 7, extends perpendicularly from this basic element 7.1, as can be seen in FIG. 8b. At the end of the basic element 7.1 which is opposite the first limb element 7.2, there is arranged a second limb element 7.3, which is bent with respect to the basic element 7.1 and forms a smaller angle with it than the first limb element 7.2 does. In the exemplary embodiment, the angle between the second limb element 7.3 and the basic element 7.1 is approximately 60 degrees. Furthermore, the hinge bar 7 has multiple mounting points 7.4, each of which serves to mount a hinged closure 1. The mounting points 7.4 each have two mounting bolts 7.41, which extend perpendicularly to the basic element 7.1 and are fixedly connected to the basic element 7.1. Via these mounting bolts 7.1, the hinged closures 1, or the hinge base 2.1 and the latch holder 2.2, can be connected both to one another and to the hinge bar 7. Furthermore, the mounting points 7.4 have a respective mounting recess 7.42, which extends both through the basic element 7.1 and through the first limb element 7.2, as can be seen in the illustrations of FIGS. 7a to 7e.
[0140] When mounting a hinged closure 7, it is then the case that firstly the hinge base 2.1 is placed into the mounting recess 7.42, with the result that the mounting bolts 7.41 penetrate the bores of the hinge base 2.1 that are provided for this. Owing to the size of the mounting recesses 7.42, which is adapted to the hinge base 2.1, and owing to the position of the mounting bolts 7.41, the hinge basis 2.1 can be placed into the hinge bar 7 only in a predefined position. The rear side, facing the pivot pin receptacle 2.17, of the mounting portion 2.18 then rests on the inner side of the basic element 7.1 of the hinge bar 7, and the pivot pin receptacle 2.17 projects beyond the hinge bar 7, as can be seen for example also in FIGS. 8a and 8b.
[0141] After the hinge base 2.1 has been mounted, the drive rod 6.1 is inserted into the hinge bar 7, with the result that said drive rod extends parallel to the basic element 7.1. Owing to the drive rod sliding surface 2.16, which is recessed with respect to the mounting portion 2.8, the drive rod 6.1 can be placed against the corresponding edge of the hinge base 2.1, with the result that the guides 2.11 lie under the guide slots 6.11 and, owing to the overlap, a substantially circular passage through the drive rod 6.1 and the hinge base 2.1 is produced.
[0142] In a subsequent step, the latch 4 is then placed into the hinge base 2.1, as can be seen in FIG. 7c. Two of the four overall guide elements 4.11 then extend through the two guide slots 6.11, arranged parallel to one another, of the drive rod 6.1 as far as the guides 2.11 of the hinge base 2.1. In this respect, the latching portion 4.2 of the latch 4 faces in the direction of the pivot pin receptacle 2.17. Subsequently, the latch holder 2.2 is then mounted and positioned in such a way that the two mounting bolts 7.41 extend through the two bores in the connecting projection 2.24 of the latch holder 2.2. The latch holder 2.2 then engages around the latch 4 and secures it against inadvertent movement. In the process, the guide elements 4.11 of the latch 4 extend into the guides 2.21 of the latch holder 2.2, and the latch 4 can move only linearly in the latching direction R. To move the latch 4, it is then possible to move the drive rod 6.1 perpendicularly to the latching direction R, as was already described above. In a final step, then the latch holder 2.2, and thus also the latch 4, and the hinge base 2.1 are fastened to the hinge bar 7 via nuts that can be screwed onto the mounting bolts 7.41, as can be seen in FIG. 7d. Furthermore, it can also be seen that the drive rod 7 is connected to two hinged closures 1, or to two latches 4, and/or that the guide elements 4.11 of two latches 4 are each guided in guide slots 6.11, arranged in the two end regions, of the guide rod 6.1.
[0143] Since the first hinge element 2 and the drive rods 6.1 for moving the latch 4 have then been mounted in the hinge bar 7, the drive device 6.2 which makes it possible to move the drive rods 6.1 can be mounted. As was already described above, the drive device 6.2 is in the form of a premounted mounting unit, with the result that it can be mounted as a whole in the hinge bar 7. The hinge bar 7 has a mounting point 7.6 for the drive device 6.2, which mounting point has suitably aligned mounting bolts 7.61 and corresponding recesses, with the result that the actuating element 6.24 can be actuated from the outside. As can be seen in FIG. 7e, the mounting point 7.6 has both a recess for the blocking device 6.3 arranged above the drive housing 6.25 and a recess for a blocking device 6.3 arranged under the drive housing 6.25. In practice, however, only one of these two recesses is provided, or one of the recesses is closed by a blind cover plate.
[0144] After mounting the drive device 6.2, the hook-shaped connecting portions at the ends of the actuating rod 6.23 engage in the correspondingly configured portions of the drive rod 6.1, with the result that the actuating rod 6.23 is coupled via its two end regions to two drive rods 6.1. Here, the actuating rod 6.23 in the form of a flat rod is arranged parallel to the first limb element 7.2 and thus also perpendicularly to the drive rod 6.1, which is likewise in the form of a flat rod. Via the drive device 6.2, it is then possible to jointly actuate all four hinged closures 1 at the same time. When the hinge bar 7 is correspondingly fitted with the hinged closures 1 and the drive device 6.2, this hinge assembly 11 as premounted mounting unit can then be arranged on the inner side of a door leaf 10.1. According to FIG. 3, for this purpose mounting bolts 10.4 may be arranged on the door leaf inner side, via which mounting bolts the hinge bar 7 can then be screwed onto the door leaf 10.1.
[0145] It can be seen in FIG. 3 that it is also the case that the second hinge elements 3 are already connected to the first hinge elements 2. For this, the latch 4 must be transferred to the unlocking position E, and the second hinge elements 3 can then be pushed into the first hinge elements 2, with the result that the pivot pins 3.2 of the second hinge elements 3 then lie in the pivot pin receptacles 2.17 of the hinge base 2.1. After this, the latches 4 are transferred back to the locking position V, in order to secure the pivot pin 3.2 between the latch 4 and the pivot pin receptacle 2.7. The door leaf 10.1 can then be fastened to the door frame 10.2 by fastening the second hinge elements 3 to the latter. As an alternative, it is also possible to arrange the second hinge elements 3 on the door frame 10.2 first of all and to plug the door leaf 10.1, or the corresponding hinge bases 2.1, onto the second hinge elements 3.
[0146] FIGS. 8a and 8b show one end region of the door leaf 10.1 in a closed position. The door frame 10.2 has a shoulder, at the end of which there is arranged a seal 10.5, which is compressed by the door leaf 10.1 in the closed position. Furthermore, the shoulder, extending in the free frame cross section, of the door frame 10.2 has a mounting region, which extends parallel to the surface of the door leaf 10.1 and on which the second hinge element 3 is arranged. The hinge assembly 11 illustrated in FIG. 7f is arranged on the inner side, which faces the door frame 10.2, of the door leaf 10.1. In this respect, FIG. 8a corresponds to a sectional view through the latch 4. Accordingly, it is also possible to see only part of the basic element 7.1 and the second, bent limb element 7.3 of the hinge bar 7. The latch 4 is in the locking position V, with the result that it secures the pivot pin 3.2 in the pivot pin receptacle 2.17 and no translational movement of the two hinge elements 2, 3, but only a rotational movement about the pivot axis S, is possible. The drive rod 6.1 can be seen in the form of a flat element in FIG. 8a, and is moved in the viewing direction, that is to say perpendicularly to the plane of the page, for the purpose of moving the latch 4. Also clearly visible is the free space into which the latch 4 is moved in the course of transferring from the locking position V to the unlocking position E. In the background can be seen the drive device 6.2, or the screw, via which the actuating element 6.24 and the pinion 6.22 are secured to the drive housing 6.25 in the axial direction.
[0147] Also visible in FIG. 8b is the entire hinge bar 7, that is to say also the first limb element 7.2, which bears against a bent edge of the door leaf 10.1 that faces in the direction of the door frame 10.2. Since the hinge element 1 is not illustrated in a sectional view in the view according to FIG. 8b itself, the latch 4 received between the hinge base 2.1 and the latch holder 2.2 inside the first hinge element 2 cannot be seen. However, both the mounting bolt 10.4, via which the hinge assembly 11, or the hinge bar 7, is arranged on the inner side of the door leaf 10.1, and the mounting bolt 7.41, via which the hinge base 2.1 and the latch holder 2.2 are connected to the hinge bar 7, can be seen.
[0148] The illustration of FIG. 9 basically corresponds to the view of FIG. 8a, but the latch 4 is in the unlocking position E, so that the door leaf 10.1 can be moved in translation with respect to the door frame 10.2 and the door leaf 10.1 can be pivoted for example about the left-hand pivot axis S illustrated in FIG. 10. The guide elements 4.1 of the latch 4 are located in the end region of the S-shaped guide slot 6.11, with the result that, in this position, the latch 4 also no longer lies in the receiving region 3.4 between the pivot pin 3.2 and the mounting region 3.1 of the second hinge element 3. FIG. 10 then shows the oppositely situated end region of the door leaf 10.1 in a pivoted position. The hinge elements 1 of the hinge assembly 11 arranged in this end region are in the locking position V, with the result that it is not possible to pivot the door leaf 10.1.
[0149] The second configuration, illustrated in FIGS. 14 to 17, relates to a hinge bar 7, or a hinge assembly 11, which is arranged not on the inner side of the door leaf 10.1 but on the outer side of the door leaf 10.1. Since the hinge bars 7 are correspondingly visible from the outside, in addition to the configuration described above, they also have a hinge bar cover plate 7.7 and, at the upper and lower ends, end elements 7.8. The differences of the hinge elements 2, 3 with respect to the first embodiment will be explained in more detail below on the basis of FIGS. 19a to 21.
[0150] In a similar way to the illustrations in FIGS. 7a to 7f, FIGS. 18a to 18e show the mounting of the individual components of the hinge assembly 11. In order to be able to see both end regions of the hinge bar 7, the center region of the hinge bar 7 is also not illustrated in FIGS. 18d and 18e. Since, however, the drive device 6.2 located in this region is identical to the drive device 6.2 already described above in terms of the hinge assembly 11 suitable for internal mounting, reference is made to the description above with respect to the configuration and attachment of the drive device 6.2.
[0151] In the case of the hinge assembly 11 for external mounting, firstly the hinge bar 7 is pushed into the hinge bar cover plate 7.7, as can be seen in FIG. 18a. Since the hinge bar 7 is identical both for internal mounting and for external mounting, reference is also made to the above description in this regard. The mounting of the hinge base 2.1 that is illustrated in FIGS. 18b and 18c, and the drive rod 6.1, are likewise identical to what was described above with regard to FIGS. 7a and 7b. The mounting of the latch 4 and of the latch holder 2.2 is therefore also not illustrated in FIGS. 18a to 18e.
[0152] By contrast to the hinge assembly 11 for internal mounting, the hinge bar cover plate 7.7 is connected to the hinge bar 7 after the first hinge element 2 has been mounted in the case of the hinge assembly 11 for external mounting. For this, a mounting element 7.5 in the form of a pressure piece is used, which is depicted in the illustration of FIG. 18d. The pressure piece is supported against the hinge bar 7 and has two projections formed in the manner of wings, which engage behind or in corresponding notches in the hinge bar cover plate 7.7 in the connected position. The pressure piece consequently clamps the hinge bar cover plate 7.7 against the hinge bar 7. For mounting purposes, the pressure piece is firstly introduced into the hinge bar 7 and then rotated by 90°, with the result that the projections engage under the hinge bar cover plate 7.7, or in the corresponding recess. By virtue of the residual stress of the material of the pressure piece, the hinge bar cover plate 7.7 is then connected to the hinge bar 7 in a frictional engagement, with the result that there is no need, for example, for screws that are visible from the outside to be screwed into the hinge bar cover plate 7.7. In a final step, the ends of the hinge bar 7, or of the hinge bar cover plate 7.7, are then also closed by end elements 7.8, as can be seen in FIG. 18e.
[0153] In a similar way to FIGS. 8a, 8b, FIGS. 19a and 19b show the hinge assembly 1 arranged on the outer side of the door leaf 10.1. An essential difference is that the first hinge element 2 is longer for external mounting than for internal mounting. This is associated with the fact that the second hinge element 3 must span not only the distance between the door frame 10.2 and the door leaf 10.2, but additionally also the height of the hinge bar 7. What then also results from this is a pivot axis S which is further away from the door frame 10.2. Nevertheless, the door leaf 10.1 overall is closer to the door frame 10.2 in the case of external mounting, since no or less space is required there for the hinge assembly 11, as is evident from a comparison of FIGS. 19a and 8a. In addition, what also results is a larger free door frame cross section, since, in the door frame 10.2, all that is required is enough space for mounting the second hinge element 3, but not additionally also for the first hinge element 2, or the hinge bar 7, and the drive actuation means 6.2.
[0154] What can be seen in FIG. 19b is the mounting element 7.5, and also the projections which engage behind the hinge bar cover plate 7.7 and which press the hinge bar cover plate 7.7 against the hinge bar 7 as a result. With regard to FIGS. 20 and 21, reference is made to the description of FIGS. 9 and 10.
[0155] In order to fasten the hinge assembly 11 to the outer side of the door leaf 10.1, according to FIG. 16 mounting bolts 10.3 in the form of hexagon socket screws are provided. These mounting bolts are screwed from the inside through the door leaf 10.1 and then into the hinge bar 7, so that no screws can be seen from the outside. As an alternative, it is also possible to screw the screws into the mounting element 7.5.
[0156] Overall, the hinge assemblies 11 for internal mounting and for external mounting differ only slightly from one another, with the result that it is possible to easily convert or easily adapt the premounted components.
