Description

Hinge lock

The invention relates to a hinge lock for locking a door leaf relative to a door frame and for pivoting the door leaf relative to the door frame, with a first hinge element for arrangement on the door leaf and a second hinge element for arrangement on the door frame second hinge elements can be locked against one another by means of a bolt that can be moved back and forth in a locking direction between an unlocking position and a locking position. Another object of the invention is a door with a hinge lock. Hinge locks are understood quite generally to be those hinges that can be used on the one hand as a hinge on the other hand as a lock, so that they have a double function in this respect. If a corresponding hinge lock is used, for example, on a door, the door leaf can be pivoted around the hinge lock and thereby opened, but the door leaf can also be locked with respect to the door frame via the hinge lock. The range of applications of such hinge locks therefore extends to very different areas of technology. These can be used, for example, not only on doors, but also on windows, flaps, lids, hatches or other pivoting locking elements.

Hinge locks generally have two hinge elements that can be moved relative to one another, the first hinge element being arranged on a door leaf that can pivot relative to the door frame and the second correspondingly on the door frame. The two hinge elements can be locked against one another via a bolt that can be moved to and fro in a locking position between an unlocking position and a locking position. In the locking position, the two hinge elements are connected to one another so that they can pivot, so that the hinge lock can then function as a hinge.

In the unlocked position, the two hinge elements are no longer connected to one another, so that in this position the door leaf is then no longer fixed with respect to the door frame, at least via the corresponding hinge lock, and the door can be opened. As a rule, the door leaf is then pivoted about a pivot axis which is arranged in an end region of the door leaf opposite the hinge lock. Due to the double function of the hinge lock, several hinge locks are often arranged on a door. As a rule, the first hinge elements are all arranged on the same side of the door leaf, but in opposite end regions of the door leaf. The term end area is understood to mean the area in the vicinity of the door edges on the edge of the door leaf, in which hinges or locks are usually arranged. When all the hinge locks are in the locking position, the door leaf is fixed in relation to the door frame and therefore cannot be moved. To open the door, the latches of the hinge locks, which are arranged in one end area of the door, can be transferred from the locking position to the unlocking position and the door leaf can then be pivoted about the pivot axis of the locked hinge locks of the other end area. The locked hinge locks then act as hinges.

Depending on which of the hinge locks are locked and unlocked, the door leaf can accordingly be opened once to the left and once to the right. Theoretically it is also possible to arrange the hinge locks above and below or even in all four end areas of the door leaf. Then the door leaf could, for example, also be pivoted upwards or downwards. Furthermore, it is also possible to move all hinge locks of the door into the unlocked position. The door leaf is then no longer fixed with respect to the door frame, but it can then be removed from the door frame.

A corresponding hinge lock is described, for example, in DE 10 2015 117 505 B3. This hinge lock has a linearly movable bolt which can be moved back and forth between the locking position and the unlocking position via a pivotable hand lever. Although this actuation has proven itself in practice, it can, for example, lead to problems with hinge locks that are difficult to access. Because in order to lock or unlock the hinge lock, the locking movement must be carried out by hand directly on the corresponding hinge lock. Especially with high doors, such as those used in particular in large server or switch cabinets, the upper hinge locks can often not be reached by smaller people without additional aids, such as a stepladder.

Proceeding from this, the invention provides the object of specifying a hinge lock which enables simpler locking and unlocking even in the case of a hinge lock that is difficult to access.

This object is achieved in a hinge lock of the type mentioned at the outset in that the bolt can be moved back and forth between the unlocked position and the locked position via a drive rod that can be moved transversely to the bolt direction.

By actuation via a drive rod that can be moved transversely to the locking direction, the locking bar can be reliably locked and unlocked from a position away from the locking bar or the actual hinge lock. The longer the drive rod is, the further away the actuation point can be from the actual hinge lock, so that to a certain extent a local decoupling of the actuation from the actual hinge lock can be achieved. As a result of this local decoupling, it is also possible to move the latches of hinge locks that are themselves difficult to access.

With regard to the movement of the drive rod, it has been found to be advantageous if it can be linearly moved back and forth perpendicular to the locking direction of the locking bar. This configuration enables a large distance between the bolt and the actual actuation point of the drive rod. In this respect, the drive rod can be parallel to the pivot axis the door leaf be movable. In particular, if the hinge lock is arranged too high up and therefore cannot be reached by one person, the hinge lock can also be operated by smaller people due to the drive rod arranged parallel to the pivot axis. The drive rod can be coupled to the bolt in the manner of a corner or 90 degree deflection.

Furthermore, it has been found to be advantageous if the drive rod is part of an actuating device.

In a further development of the drive rod, it is proposed that it be designed as a flat rod. A corresponding flat bar can extend parallel to the door leaf and therefore requires little space. A flat rod has also proven itself with regard to the transmission of the movement of the drive rod to the bolt, which is explained in more detail below with regard to the further configuration of the drive rod. However, it is also possible for the drive rod to be designed as a profile rod or as a round rod. So that the bolt can be moved via the drive rod, it has proven to be advantageous if the drive rod has at least one guide slot in which the bolt, in particular a guide element of the bolt, is guided. The movement of the drive rod can be converted into a transverse or perpendicular movement of the bolt via the guide link. In terms of construction, the guide link can be designed as an elongated hole, and the bolt or a guide element of the bolt can be received in the elongated hole of the drive rod. The bolt can be mounted in such a way that it can only be moved linearly in the bolt direction, so that the bolt can be reliably moved back and forth between the unlocking position and the locking position by the movement of the drive rod. With regard to the movement of the bolt through the drive rod, it has proven to be advantageous in a further development of the invention if the drive rod has two guide links, in particular arranged parallel to one another. In this respect, a bolt can then be guided in the two guide slots, which allows a reliable movement of the bolt and reduces the risk of the bolt and / or the drive rod jamming. Furthermore, it has been found to be advantageous if the guide link is designed in an S-shape. With this configuration, a reliable movement of the bolt can be achieved with comparatively little effort. The guide link can have a start and an end area, which can be aligned parallel to one another. A straight or curved connection area can be provided between the start and end areas, so that overall an S-shaped profile results. S-shaped does not necessarily mean that the guide link has to be curved, but it can also have exclusively straight areas. The start and end areas of the guide link can extend parallel to the pivot axis so that the bolt, which can only be moved in the locking direction, does not move when the drive rod moves when the bolt is guided in the start or end area. Only when the drive rod has been moved in such a way that the bolt is guided in the connecting area is a movement of the drive rod converted into a corresponding transverse movement of the bolt.

The initial actuation force required to move the bolt can be reduced by an S-shaped guide slot. Because due to the transition between the start and the connection area and between the end area and the connection area, the bolt can initially only move slightly when the drive rod moves, and only then then in the middle part of the connecting area the movement of the drive rod can initiate, for example, a movement that is oriented transversely thereto and of the same size as the bolt. To move the bolt, it is advantageous if the guide slot or if the connecting area of the guide slot encloses an angle of 45 ° with the bolt direction. In the case of several guide slots, in particular two guide slots, these can be configured parallel to one another.

With regard to the design of the hinge lock, it has also been found to be advantageous if the first hinge element is designed in several parts and has a hinge base and a bolt holder, the bolt being movably received between the hinge base and the bolt holder. A corresponding multi-part design offers advantages with regard to the assembly of the elements, since these can be assembled one after the other. The bolt can be accommodated between the hinge base and the bolt holder so that it can move linearly so that the bolt can slide back and forth between the hinge base and the bolt holder when it moves in the locking direction between the locking position and the unlocking position. The hinge base and the bolt holder can serve as a guide for the bolt in the direction of the bolt.

Furthermore, it has been found to be advantageous if the bolt is held captive between the hinge base and the bolt holder. The hinge base and the bolt holder can encompass the bolt in the connected position in such a way that it cannot be removed, but is held securely between the two elements. As a result, the bolt can still be reliably moved in the bolt direction, even after a long period of operation and possibly also after a certain amount of wear, and cannot slip out of the hinge element. In this respect, this then also ensures reliable operation of the hinge lock over a longer period of time. To the latch from the hinge lock To remove, the bolt holder and the hinge base must first be separated from one another.

In order to ensure a reliable movement of the bolt, it has been found to be advantageous if the bolt is guided in the hinge base and / or in the bolt holder. For guidance, in particular on opposite sides, the bolt can have at least one guide element designed as a guide bolt, which can be guided in a corresponding guide of the bolt holder or the hinge base. Advantageously, one, in particular two, guide elements on one side of the bolt are guided in the bolt holder and one, in particular two, guide elements on an opposite side of the bolt are guided in the hinge base. This double guide enables reliable movement of the bolt. By means of two guide elements per side of the bolt it can also be ensured that the bolt does not tilt during a corresponding movement in the bolt direction and that, in this respect, reliable unlocking and locking can be ensured. The hinge base and / or the bolt holder can have guides designed in the manner of elongated holes, which in this respect enable a linear movement of the bolt. The elongated holes of the respective elements can be arranged parallel to one another and the elongated holes of the hinge base and the bolt holder can be opposite one another and aligned with one another.

At least one guide element can extend through the link of the drive rod and extend into the guide of the bolt holder or into the guide of the hinge base. With this configuration, the drive rod is positively connected to the first hinge element and a movement of the drive rod causes the guide element of the bolt to move both in the guide slot and in the guides of the bolt holder and / or the hinge base. With regard to the arrangement of the drive rod, it has proven to be advantageous if it is arranged, at least in sections, between the bolt and the hinge base. The drive rod can thus slide back and forth between the bolt and the hinge base during a movement and thereby move the bolt to and fro accordingly in the locking direction. The drive rod can thus be arranged at least in sections in the hinge lock. The hinge base and also the latch can have corresponding sliding surfaces that facilitate sliding of the drive rod back and forth. The design of the drive rod as a flat rod has proven to be particularly advantageous in this context, since this configuration enables the hinge lock to have only a small structural volume and the space requirement of the drive rod between the bolt and the hinge base is low. Alternatively, it is also possible for the drive rod to be arranged at least in sections between the bolt and the bolt holder. In this embodiment, too, the drive rod can slide back and forth in the hinge lock and move the bolt accordingly in the bolt direction. Furthermore, it has been found to be advantageous if the bolt holder engages around the side of the bolt. The bolt holder can in this respect have two guide surfaces between which the bolt is guided and which in this respect serve for a lateral linear guide of the bolt. This configuration not only additionally guides the bolt, it also simplifies assembly, since the bolt holder is arranged in a position relative to the bolt that is firmly defined by the guide surfaces. Subsequent alignment is therefore basically not necessary.

In a further development of the bolt, it is proposed that the bolt have a bolt section and a movement section. The locking section can be designed in the form of a block and in this respect offer a high level of stability, so that the bolt can securely connect the two hinge elements to one another in the locked position. The movement section can be designed to be flat and extend perpendicular to the locking section. The movement section can be guided in the bolt holder, and the guide elements can also be arranged on the bolt section. In this respect, the movement section can serve to ensure a movement of the bolt between the locking position and the unlocking position. The movement section can be arranged parallel to the drive rod, so that a compact structure results.

The locking section can be guided in the hinge base. The hinge base can have guide surfaces which represent a further guide for the bolt and only allow a linear movement between the locked position and the unlocked position.

The locking section can have at least one recess through which the second hinge element, in particular a stiffening rib of the second hinge element, can extend in the locking position. The recesses can extend perpendicular to the locking direction. It is advantageous if the locking section has two, in particular parallel, recesses. A stiffening rib of the second hinge element can extend through these two recesses so that the bolt can laterally encompass the second hinge element or the reinforcing ribs of the second hinge element in the locking position. Furthermore, the reinforcing ribs can thus also serve as a guide for the bolt. When moving from the unlocked position into the locked position, the recesses of the bolt can be moved over the stiffening ribs of the second hinge element. Furthermore, the recess can subdivide the locking section into two locking blocks. If there are two recesses, they can subdivide the bolt section accordingly into three bolt blocks. In a further advantageous embodiment, the hinge base can have a guide projection which, in the unlocked position, engages in the recess of the bolt. If two recesses are provided, two guide projections can accordingly also be provided, which can then each engage in a recess of the bolt. When moving from the locking position to the unlocking position, the bolt or the bolt blocks are then moved back and forth between the guide projections of the hinge base and the stiffening ribs of the second hinge element.

With regard to the connection of the hinge base to the bolt holder, it has proven to be advantageous if the hinge base is detachably connected to the bolt holder. This simplifies the assembly of the hinge lock, since the bolt can first be inserted into the hinge base and then the bolt holder can be detachably connected to the hinge base. The bolt can then be received between the hinge base and the bolt holder in a form-fitting but linearly movable manner. It is also advantageous if the hinge base and the bolt holder can be connected to one another via at least one assembly bolt. Both the hinge base and the bolt holder can have corresponding recesses or bores through which the assembly bolt can reach. It is also possible that the mounting bolt is firmly connected to the bolt holder or to the hinge base. In this embodiment, only the other element then accordingly has a recess or a bore for the mounting bolt. The assembly bolt can have a thread so that the bolt holder and the hinge base can then be connected to one another via a nut that can be screwed onto the assembly bolt. Furthermore, it is also possible for the assembly bolt to be part of the door leaf and, for example, to be fixed to it connected is. The assembly bolt can, for example, be welded to the door leaf and in this respect be designed as a weld-on bolt.

Furthermore, it has been found to be advantageous if the bolt holder and the hinge base are connected to one another via two assembly bolts. This configuration ensures a reliable fixation of the two elements. Furthermore, it is possible that the hinge base can also be connected to a door or a door leaf via the same mounting bolts. In this respect, the hinge base and the bolt holder can then jointly via one or, if necessary, several

Hinge bolts are connected to the door leaf. It is also possible to connect the elements not directly to a door but to a hinge strip. The mounting bolt can then, for example, be part of the hinge strip and be fastened in or on it

The more precise design of the hinge strip and the assembly of the elements on the hinge strip are described in more detail below.

With regard to the mounting bolt, it has proven to be advantageous if it extends perpendicular to the bolt direction and correspondingly in the normal direction to the door leaf. In an alternative embodiment, however, the mounting bolt can also extend parallel to the locking direction. In this embodiment, the bolt holder can have a receiving bush, for example with an internal thread, and the hinge base can, for example, have a bore for the mounting bolts. The mounting bolt can then be screwed into the receiving socket and thus connect the bolt holder to the hinge base. In this embodiment, the hinge base can be connected to the door or to the hinge strip via other mounting bolts. The hinge base can be fitted with an assembly to connect it to the door or to the hinge strip. have portion which can extend parallel to the surface of the door or parallel to the hinge strip.

The bolt holder and the hinge base can each have, in particular flat, connecting projections and the receptacles for receiving the mounting bolt or bolts can be arranged in the connecting projections. The first hinge element can have a receiving groove in which the drive rod can be guided. The receiving groove can arise in that the two connecting projections project in different directions and lie on top of one another. The receiving groove can accordingly be formed by the hinge base and the bolt holder. The receiving groove can extend perpendicular to the locking direction and in the longitudinal direction of the hinge strip. With regard to the design of the second hinge element, it has proven to be advantageous if it is designed as a hinge bracket that can be connected to the door frame.

The second hinge element can have a mounting area for mounting on a door frame. The assembly area can have one, in particular two, assembly bores and can be screwed to the door frame via these. It is advantageous if the second hinge element is connected to a surface of the door frame which, in the closed position of the door, is aligned parallel to the door leaf. The second hinge element can have a pivot pin defining a pivot axis. In the locking position, the first hinge element and thus also the door leaf can be pivoted about the pivot axis of the second hinge element connected to the door frame. The second hinge element can have a connecting area which connects the pivot pin to the mounting area. When the door is closed, the connection area can extend perpendicular to the door leaf. Of the The connection area can have one, in particular two, stiffening ribs which ensure sufficient stability of the second hinge element so that the door weight can be absorbed by the corresponding connection area even with heavy doors. The pivot pin can in particular protrude laterally with respect to the connection area, so that a T-shaped contour of the second hinge element results.

The second hinge element can also have a receiving area for receiving the bolt in the locking position. The receiving area can be arranged between the pivot bolt and the assembly area, and the bolt can be retracted into this receiving area in the locking position in order to secure the pivot bolt in the hinge base. The hinge base can have a pivot pin receptacle to accommodate the pivot pin accordingly. The pivot pin receptacle can encompass the pivot pin of the second hinge element in sections and in this respect ensure reliable mounting of the door leaf on the door frame. The pivot pin receptacle or the edges of the pivot pin receptacle can also function as a stop and in this respect limit the opening angle of the door leaf with respect to the door frame.

The pivot pin receptacle can be divided and have two pivot pin receptacle areas. A part of the pivot pin can be received in each of the pivot pin receptacles. The second hinge element or the connecting area of the second hinge element can extend between the two pivot pin receiving areas. When the door is closed, the connecting area of the second hinge element can then lie between the two pivot pin receiving areas. In a further development of the invention, it has been found to be advantageous if the pivot bolt is secured in the locking position between the hinge base, in particular the pivot bolt receptacle, and the bolt, in particular in the bolt section. The latch and the pivot pin receptacle can encompass the pivot pin of the second hinge element in a form-fitting manner so that no translational movement of the two hinge elements with respect to one another, but only a rotational movement of the two hinge elements with respect to one another is possible. In this respect, the first hinge element and the second hinge element can then be pivotably connected to one another in the locking position. The first hinge element can be pivotable about the pivot axis or about the pivot pin of the second hinge element. In the unlocked position, the bolt can no longer secure the pivot bolt of the second hinge element, so that the two hinge elements can then be moved in a translatory manner relative to one another. In this position, the door leaf can be removed from the door frame, for example, or the door or the door leaf can be pivoted about another pivot axis.

Furthermore, it has been found to be advantageous if an emergency release is provided with which the bolt can be moved from the locking position into the unlocking position. The emergency release can be actuated from both sides of the door and to this extent ensure reliable opening of the door in an emergency situation. The bolt can be transferred from the locking position to the unlocking position via a corresponding emergency release, but not back into the locking position.

The bolt holder, the hinge base and the bolt can be designed as injection molded parts and consist of plastic. Furthermore, the Elements also consist of metal, in particular stainless steel or cast steel. The same applies to the drive rod, the actuating device and the second hinge element. The elements can also consist of different materials.

Furthermore, with regard to the object mentioned at the beginning, a door with a hinge lock is proposed, the hinge lock being designed in the manner described above. The advantages already described with regard to the hinge lock result.

It is advantageous if the second hinge element is arranged on the door frame and the first hinge element is arranged on the door leaf, so that the door leaf is connected to the door frame via the hinge lock. To connect the door leaf to the door frame, several hinge locks have proven to be advantageous, which are arranged in opposite end areas of the door leaf. Depending on the height of the door leaf, for example four, six, eight or even more hinge locks can be provided. The hinge locks can be opposite one another in pairs and can be arranged in the end regions of the door leaf. So that the first hinge elements can be connected to the second hinge elements, the first hinge elements can in particular protrude laterally with respect to the door leaf. It is also possible for the door leaf to have assembly recesses through which the second hinge element can extend and into the first or into the pivot pin receptacles of the hinge base.

A hinge assembly is also proposed with at least two hinge locks for locking a door leaf with respect to a door frame and for pivoting the door leaf with respect to the door frame, the hinge assembly having an actuating device for jointly actuating the hinge locks. Features of the The hinge assembly and the mode of operation of the actuation are described in more detail below. If the following descriptions should contradict the above description, the above description should be authoritative.

A hinge assembly is understood to mean interrelated elements that can be preassembled together and then used as an assembly. The actuating device allows the at least two hinge locks, in particular all hinge locks, of the hinge assembly to be locked and unlocked together. It is therefore not necessary to lock or unlock each of the hinge locks individually, which is associated with a clear simplification and time saving. It is advantageous if each hinge assembly can only be actuated via a single device with which all the hinge closures of the hinge assembly can then be actuated together centrally. This does not rule out the fact that hinge locks of the hinge assembly can also be actuated individually, in particular additionally.

In a further development, it is proposed that the hinge assembly has a hinge strip which can be arranged on the door leaf and which has a plurality of assembly points for each assembly of a hinge lock. Depending on how many points the door leaf is to be connected to the door frame, a corresponding number of assembly points can be arranged on the hinge strip. For smaller doors, for example, two assembly points and thus two hinge locks per end area of the door can be sufficient. In the case of taller or heavier doors, which accordingly also have to be connected to the door frame at several points, four mounting points and thus four hinge locks per hinge assembly can be used. The hinge locks can be at the same distance from one another, so that there is a reliable connection between the door leaf and the door frame. Furthermore, it is also possible for the hinge strip to have more mounting points than are ultimately used for the hinge locks. For example, it is conceivable that the hinge strip has four mounting points, but a hinge lock is only mounted at two of these mounting points.

With regard to the design of the hinge lock, it has proven to be advantageous if it has a first and a second hinge element which can be pivoted relative to one another to move the door leaf about a pivot axis. For this purpose, the first hinge element can be arranged on the door leaf or on the hinge strip that can be arranged on the door leaf, and the second hinge element can be arranged on the door frame. Due to the pivotability of the two hinge elements, the door leaf can then accordingly also be pivoted relative to the door frame.

With regard to the arrangement of the hinge strip on the door leaf, it has also proven to be advantageous if the hinge strip extends parallel to the pivot axis. The first and second hinge elements of the multiple hinge locks of a hinge assembly can all be pivotable about the same pivot axis, so that the hinge assembly is thus assigned a single pivot axis. The door leaf generally has a rectangular shape and the pivot axis can extend parallel to the longer edge of the door leaf. Accordingly, the hinge strip can also be arranged parallel to the longer edge of the door. With regard to the pivot axis, it is also proposed that it be located outside the hinge strip. This configuration offers structural advantages, since the door leaf can then be opened and closed more easily and a collision of the elements can be prevented.

With regard to assembly, it has been found to be advantageous if the hinge strip and the hinge locks are designed as a preassembled assembly unit. This offers advantages in terms of assembly.

This is because before the hinge strip is arranged on a door leaf, the hinge locks can be connected to the hinge strip and then arranged in one step as an assembly unit on the door leaf. This enables simple and rapid assembly, since the two assembly steps, that is to say the assembly of the hinge locks on the hinge strip and the hinge strip on the door leaf, are separated from one another. In particular if a hinge strip has many hinge locks and / or if there are several hinge strips arranged on a door leaf, this pre-assembly leads to a significant saving in time.

It has also been found to be advantageous if the hinge strip can be arranged either on the inside of the door leaf or on the outside of the door leaf. This variability allows door leaves and door frames of different types and with different geometric requirements to be connected to the hinge strip. The various advantages that result from external and internal installation are explained in more detail below. Only very few changes need to be made to the hinge strip and to the hinge locks in order to convert, for example, from internal to external installation.

With regard to the design of the hinge strip, it has been found to be advantageous if it comprises a base element for arrangement on the door leaf and two leg elements. The hinge strip can thus have an essentially U-shaped cross-sectional shape, and the two the leg elements can be arranged parallel to one another and perpendicular to the base element. Furthermore, however, only the first leg element can enclose a right angle with the basic element and the second leg element can enclose a smaller angle with the basic element, for example in the range from 30 to 70 degrees. As a result of this bending of the second leg element, the elements arranged in the hinge strip can, in particular additionally, be fixed in the hinge strip. Less installation space is also required due to the smaller angle. It is advantageous if the first leg element is closer to the pivot axis of the hinge assembly than the second leg element. The first leg element can in this respect be assigned to the edge of the door leaf and the second leg element can point towards the center of the door leaf. With regard to the design of the hinge locks, it has been found to be advantageous if the second hinge element and the first hinge element can be locked against one another via a bolt that can be moved to and fro in a locking direction between an unlocked position and a back and forth movable bolt.

With regard to assembly, it has been found to be advantageous if the first hinge element is connected to the hinge strip. The second hinge element can be arranged on the door frame, so that after the hinge strip has been arranged on the door leaf, the door can be correspondingly pivoted relative to the door frame.

In a further development of the invention, it is proposed that the hinge strip have, in particular, preassembled assembly bolts, in particular weld bolts, for assembling the first hinge elements. The hinge locks or the first hinge elements can be securely connected to the hinge strip via the mounting bolts. The mounting bolts can be firmly connected to the hinge strip and designed as welding studs. The mounting bolts can have a thread so that the first hinge element can then be connected to the hinge strip via a nut. The respective assembly bolts can be part of the assembly points of the hinge strip, so that at least one assembly bolt is available at each assembly point. It is advantageous if each mounting point has two mounting bolts. This ensures a reliable connection of the first hinge elements to the hinge strip.

Furthermore, it has been found to be advantageous if the hinge strip has several mounting recesses for mounting the hinge locks. The mounting recesses can be part of the mounting points and each mounting point can be assigned a mounting recess. The mounting recesses can extend through the first leg element and the base element. The mounting recesses can be adapted to the hinge locks, in particular to the first hinge element, in particular to the hinge base, so that the hinge base can be placed in a predefined position in the hinge strip or in the corresponding mounting recess during assembly. This simplifies the assembly or the connection of the hinge locks with the hinge strip. When the hinge base is connected to the hinge strip, the pivot pin receptacle of the hinge base can protrude with respect to the strip. This enables the pivot axis not to be arranged in the hinge strip itself, but rather at a distance from it. With regard to the pivot axis, it has also proven to be advantageous if it is arranged at a distance from the outside of the door leaf and is arranged on the side of the door leaf opposite the door frame. It has also proven to be advantageous if the assembly bolts for connecting the hinge base to the bolt holder extend through the hinge strip. In this way, not only can the hinge base be connected to the hinge strip, but at the same time the bolt holder can also be connected to the hinge base via the same assembly bolts. The mounting bolts can extend perpendicular to the base element of the hinge strip. In this respect, the respective bolt holders can also be connected to the respective hinge base at the respective mounting points, preferably via two mounting bolts in each case.

In order to lock or unlock the bolts of the hinge locks, it has proven to be advantageous if the bolts of the respective hinge locks can be moved back and forth between an unlocking position and a locking position together via the actuating device. In this way, all bolts of a hinge assembly can be moved simultaneously from the unlocked position into the locked position or from the locked position into the unlocked position by a single actuation. The door can thus be locked and unlocked very quickly.

For the corresponding actuation, it has been found to be advantageous if the actuating device has at least one drive rod for moving at least one bolt and a drive device for moving the drive rod. With a corresponding movement in the locking direction, the bolts can move parallel to the base element of the hinge strip. The drive rod can move parallel to the pivot axis or to the longitudinal axis of the hinge strip and perpendicular to the locking direction. In a further development, it is proposed that the bolts of several, in particular two, hinge locks can be moved with one drive rod. This configuration enables reliable joint actuation of the latches to be ensured. With four hinge locks and thus also four bolts, two drive rods can be provided. The corresponding drive device can be arranged between the two drive rods and then actuate them together. In this respect, several drive rods can be moved with one drive device. With regard to the design of the drive device, it has proven to be advantageous if it has a rotatable actuating element, the rotational movement of which can be converted into a linear movement of an actuating rod. This configuration ensures that the latch can be moved back and forth between the locking position and the unlocking position via, for example, a rotatable handle, a pawl, a pivot lever or also via a tool actuation. The actuating element can be accessible from the outside of the door leaf, so that all hinge locks of a hinge assembly can be locked and unlocked by hand.

The actuating rod can be designed as a toothed rack and extend flat and parallel perpendicular to the base element of the hinge strip. The actuating element can be rotatably coupled to a pinion, and the pinion can mesh with the actuating rod for linear movement of the actuating rod. For this purpose, the actuating rod can be designed as a rack with several teeth arranged next to one another or with several recesses arranged next to one another, into which the teeth of the pinion can engage. Alternatively, a belt drive or a spindle drive are also possible to convert the rotary movement into a linear movement. To move the drive rods, it has been found to be advantageous if the actuating rod for driving two drive rods is connected to these on opposite sides. The actuating rod can thus be connected to a drive rod at the upper and lower end. It is advantageous if the actuating rod is detachably connected to the drive rods at the corresponding ends. In practice it has been found to be advantageous, for example, if the actuating rod is suspended in the drive rod. For this purpose, the actuating rod can have connection sections configured in the manner of hooks at both ends and the drive rod can have connection sections correspondingly configured as recesses. It is also possible for drive rods not to be connected to the actuating rod, but to be connected to other drive rods that are connected to the actuating rod. In this respect, the drive rods can be arranged successively one behind the other and more than two drive rods can also be moved via the actuation rod.

Furthermore, it has been found to be advantageous if the drive device has a drive housing which is connected to the hinge strip. The drive device can thus be fastened in the hinge strip or connected to it via the hinge housing. The hinge strip can have a mounting point for mounting the drive device. The mounting point can comprise mounting bolts by means of which the drive housing can be connected to the hinge strip, in particular in a detachable manner. The assembly bolts for assembling the drive device can be designed analogously to the assembly bolts for assembling the first hinge element. In this respect, the assembly bolts can extend through the drive device or through the drive housing and can then be connected to the hinge strip, for example via nuts. The drive housing can serve as a bearing for the pinion and for the actuating element. When actuated, the actuating element and the pinion, which is rotatably coupled to the actuating element, can be rotated relative to the drive housing.

Furthermore, it has been found to be advantageous if the drive housing is connected to a linear guide for guiding the movement of the actuating rod. A reliable movement of the actuating rod can thus be ensured by the linear guide and it cannot jam or get caught during a movement. Furthermore, by connecting the linear guide to the drive housing, the linear guide can also be coupled to the hinge strip so that it accordingly does not move with the actuating rod.

With regard to the drive device, it has proven to be advantageous if it is designed as a preassembled assembly unit. The drive device can thus be inserted as a whole into the hinge strip and then connected to it, which simplifies the assembly as a whole. When installing the drive device in the hinge strip, the drive housing can be connected to the hinge strip via the mounting bolts and the actuating rod can be connected accordingly to the drive rods to be driven.

In a further development of the drive device, it is also proposed that it have a locking device which prevents movement of the actuating rod in a locking position. When the locking device is in the locking position, the latches of the hinge locks can no longer be moved and, for example, if the hinge locks are in the locking position, the door can then be secured against unintentional opening. The locking device can comprise a lock cylinder configured in the manner of a lock and have a rotatable locking tongue. In the locked position, the locking tongue can engage in a recess in the actuating rod so that it can no longer be used. is moveable. By blocking the movement of the actuating rod, a rotary movement of the actuating element can thus also be blocked. The locking device can be connected or connectable to the drive housing and configured as an additional module that can be used as an alternative. In this respect, the locking device can be plugged into the drive housing in the manner of a plug-in connection and connected to it. The housing can have several receptacles for the locking device and the locking device can be connected to one of these receptacles, for example depending on the orientation of the hinge strip. The locking device can also be preassembled as part of the drive device and then installed in the hinge strip together with the other components.

With regard to the design of the hinge lock, it has proven to be advantageous if the second hinge element, in particular the connecting area of the second hinge element, extends through the hinge strip, in particular through the mounting recess for the respective hinge lock. The second hinge element can thus also be preassembled. In practice, however, it has been found to be advantageous if the second hinge element is first connected to the door frame and the hinge strip, together with the other parts of the hinge locks, is first connected to the door leaf. The door leaf can then be connected to the door frame very easily. For this, only the latches of the hinge locks have to be brought into an unlocked position and the pivot pin of the respective second hinge element has to be inserted into the respective first hinge element accordingly. When the two hinge elements have been brought together accordingly, the bolts can be brought into the locking position, so that the door leaf is then connected to the door frame so that it can pivot. The assembly area of the second hinge element and the pivot pin of the second hinge element can then lie opposite one another in relation to the hinge strip. Furthermore, it has proven to be advantageous, in particular with regard to external assembly, if the hinge strip is arranged in a hinge strip cover. In the case of external installation, it is not the hinge strip, but only the hinge strip cover that can be visible.

Since the hinge strip is not visible from the outside in any case during internal assembly, a corresponding hinge strip cover is then not absolutely necessary. The hinge strip cover can cover the hinge strip all around. The hinge strip cover can have assembly recesses that can be configured to correspond to the assembly recesses of the hinge strip, so that the hinge strip cover does not impair or make the assembly of the hinge locks difficult. At the upper and lower end, the hinge strip cover can be closed by means of closing elements that can be plugged into the hinge strip cover. The hinge strip cover can also encompass the door leaf from one side.

To connect the hinge strip cover to the hinge strip, the hinge strip can have mounting elements in particular at the upper and lower end. These assembly elements can have wing-like projections which can grip into or behind the hinge strip cover. The assembly elements can be designed as pressure pieces and tension the hinge strip cover against the hinge strip. The hinge strip cover can be positively connected to the hinge strip via the mounting elements.

During assembly, the assembly elements can be introduced into the hinge strip in an assembly position, and then by turning, in particular 90 degrees, the projections of the assembly elements can engage or engage behind the hinge strip cover and thus connect the hinge strip cover to the hinge strip. To the To remove the hinge strip cover, the assembly elements must first be turned back 90 degrees. The hinge strip cover can thus be connected to the hinge strip in a detachable manner and without screws that are visible from the outside.

Furthermore, a door with a door leaf, a door frame and a hinge assembly is proposed, the hinge assembly being designed in the manner described above. The advantages already described with regard to the hinge assembly result.

With regard to the door, it has proven to be advantageous if the hinge strip is arranged on the outside of the door leaf. "Outside" means the side of the door leaf that faces away from the door frame. In this external installation, the free door cross-section can be larger than in an internal installation, since there only needs to be enough space on the door frame for installation of the second hinge element or for installation of the installation area of the second hinge element.

Mounting bolts, for example in the form of screws, in particular Allen screws, can be used to connect the door leaf to the hinge strip or the hinge assembly. These can reach through the door from the inside of the door leaf and then be screwed into the hinge strip. The mounting bolts advantageously do not penetrate the hinge strip cover, so that they cannot be seen on the outside of the door leaf.

In an alternative embodiment, it has been found to be advantageous if the hinge strip is arranged on the inside of the door leaf. By "inside" is meant the side of the door leaf that faces the door frame. In this configuration, the hinge strip is not visible from the outside, but the free cross-section of the door is reduced. frame, since not only enough space is required on the inside of the door leaf to mount the second hinge lock, but also the hinge strip has to find space between the door frame and the door leaf.

The door leaf can be designed as a sheet metal door leaf and have bevels pointing in the direction of the door frame in the edge areas. The hinge strip can rest against the bend, particularly when it is installed inside. In the case of external installation, the hinge strip cover can cover the fold. The door frame can have a shoulder which protrudes in the direction of the free frame cross-section and which has a mounting surface arranged parallel to the door leaf. The second hinge element can be mounted on this mounting surface. The shoulder can also have a bevel pointing in the direction of the door leaf, which is provided with a seal which is compressed by the door leaf in the closed position of the door leaf.

With regard to the door, it has also proven to be advantageous if the door leaf has mounting recesses. These assembly recesses can coincide with the assembly recesses of the hinge strip, so that the assembly recesses are aligned with one another and the hinge strip can be reliably connected to the door leaf. The door leaf can also have recesses for the actuating device so that it can be actuated from the outside of the door leaf. In the case of external installation, however, a corresponding installation recess in the door leaf for the actuating element of the drive device is not required. In this case, it is sufficient if the hinge strip and the hinge strip cover have corresponding recesses for the actuating element and possibly also for the locking device. A door with two hinge assemblies is also proposed. The hinge assemblies can be arranged in opposite end regions of the door leaf. The individual hinge locks of the two hinge assemblies can then lie opposite one another in pairs.

Furthermore, a method for assembling a hinge assembly is proposed, the hinge assembly being designed in the manner described above. It is proposed that first the hinge assembly is preassembled and then the hinge assembly is mounted on the door leaf. When assembling the hinge assembly, it has proven to be advantageous if the hinge base is first assembled in the hinge strip. The drive rod can then be installed. The bolt can then be installed. The bolt holder can then be installed. The drive device, in particular the already pre-assembled drive device, can then be mounted. After the hinge assembly has been installed, it can then be arranged on the door leaf.

Whether the hinge assembly is to be connected to the inside or the outside of the door leaf has basically no influence on the assembly sequence. When installing outside, the first step is to slide the hinge strip into the hinge strip cover. After the first hinge element is then connected to the hinge strip, the hinge strip cover can be connected to the hinge strip via the mounting element.

Further details and advantages of the invention are to be explained in more detail below with reference to the accompanying drawings of schematic exemplary embodiments.

Position.

Hinge locks 1 are used to lock a door leaf 10.1 in relation to a door frame 10.2 and to pivot the door leaf 10.1 in relation to the door frame 10.2, so that in this respect they have a double function. Before the more precise design of the hinge lock 1 and the actuation of the hinge lock 1 are described in more detail below, the basic function of the hinge locks 1 should first be described in more detail.

In the illustration of FIG. 1, several doors 10 arranged close to one another are shown, each with a door leaf 10.1 and a door frame 10.2. The door leaves 10.1 of the doors 10 are rectangular and significantly higher than they are wide. Such door arrangements are typically used in large servers or control cabinets. As can also be seen in FIG. 1, each of the doors 10 shown has a total of eight hinge locks 1, so that each door leaf 10.1 once to the left, i.e. around the four left hinge locks 1, and also around the four right hinge locks 1 can be pivoted and opened. In order to open the door leaf 10.1 to the left, the left hinge locks 1 must then be locked and the right hinge locks 1 must be unlocked. When the door leaf 10.1 moves to the right should be opened, the right hinge locks 1 must be locked and the left hinge locks 1 must be unlocked. When all eight hinge locks 1 of a door 10 are locked, the door leaf 10.1 is fixed with respect to the door frame 10.2, and the door leaf 10.1 can accordingly not be moved. When all eight hinge locks 1 are unlocked, the door leaf 10.1 can be removed from the door frame 10.2.

As can be seen in the illustration in FIG. The hinge strip 7, together with the respective hinge locks 1, forms a hinge assembly 11, so that each of the door leaves 10.1 shown in FIG. 1 is connected to the door frame 10.2 via two hinge assemblies 11.

Before the various configurations and mounting options of the hinge strips 7 or the hinge assemblies 11 are discussed in more detail below, the structure of the individual hinge locks 1 will now be described in more detail with reference to FIGS. 5a and 5b. In the illustration of FIGS. 5a and 5b, a hinge lock 1 is shown in an exploded illustration. The hinge closures 1 to be seen in FIGS. 1 and 2 correspond to those shown in FIGS. 5a and 5b. The hinge locks 1 essentially consist of two parts, namely 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, so that the door leaf 10.1 then accordingly about them Hinge locks 1 or about the pivot axis S of the hinge locks 1 can be pivoted. With regard to the multiple hinge closures 1 having Hinge assembly 11, the hinge elements 2, 3 of each hinge lock 1 of a hinge assembly 11 are pivotable about the same pivot axis S, so that a pivot axis S can be assigned to each hinge assembly 11. Accordingly, all the hinge elements 2, 3 of a hinge assembly 1 can be pivoted relative to one another about the same pivot axis S.

In the unlocked position E, the two hinge elements 2, 3 are no longer pivotably coupled to one another, but they are translationally movable relative to one another, so that the door leaf 10.1 is then pivoted accordingly about another pivot axis S or the door leaf 10.1 can be removed from the door frame 10.2 can, as has already been described above.

The first hinge element 2 consists of three elements, namely a hinge base 2.1, a bolt 4 that can be moved back and forth in a bolt direction R and a bolt holder 2.2. The bolt holder 2.2 and the hinge base 2.1 act as guides for the bolt 4, and the bolt 4 is captured between these two elements so that the bolt 4 can only be removed when the hinge base 2.1 and the bolt holder 2.2 are separated from each other are. Both the hinge base 2.1 and the bolt holder 2.2 have guides which are labeled 2.11 and 2.21 and in each of which a guide element 4.11 designed in the manner of a guide bolt is guided. When the bolt 4 moves in the bolt direction R, the guide elements 4.11 then move in the corresponding guides 2.11, 2.21 and any other movement of the bolt 4 is prevented. As can be seen in particular in FIG. 5b, the bolt 4 has a total of four guide pins, two of which are guided in the guide 2.11 of the hinge base 2.1 and two in the guide 2.21 of the bolt holder 2.2. The bolt holder 2.2 also has a lateral guide for the bolt 4, as can be seen in FIG. 5a. There is a giant Gel sliding surface 2.22 set back, so that a type of receptacle with two lateral guide surfaces 2.23 is created, which then laterally encompass and guide the bolt 4. As can also be seen, the bolt 4 has an essentially L-shaped cross section, and it consists of a rather flat movement section 4.1 and a bolt section 4.2 arranged perpendicular thereto. The movement section 4.1 is arranged between the hinge base 2.1 and the bolt 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 with reference to the other figures. The locking section 4.2 is block-shaped and therefore also significantly more stable than the movement section 4.1. This goes hand in hand with the fact that the locking section 4.2 in the locking position V ensures that the pivot pin 3.2 is received between the locking section 4.2 and the hinge base 2.1 or the pivot pin receptacle 2.17 of the hinge base 2.1 and is therefore exposed to relatively high forces, which is also associated with the size or weight of the door leaf 10.1.

Furthermore, the locking section 4.2 has two recesses 4.21 which subdivide the locking section 4.2 into three locking blocks 4.22. As can be seen from FIG. 5b, the hinge base 2.1 has two guide projections 2.15 which engage precisely in the recess 4.21 of the locking section 4.2 and thus also serve to guide the locking section 4.2 laterally. Furthermore, the hinge base 2.1 also has additional lateral guide surfaces 2.14, which also guide the locking section 4.2 laterally. The tripartite division of the locking section 4.2 is also due to the design of the second hinge block, which is designed in the manner of a hinge block. kidney element 3 adapted. As can be seen in FIG. 5b, the second hinge element 3 has a mounting area 3.1 with a flat surface, via which the second hinge element 3 can be connected to the door frame 10.2. The pivot pin 3.2 is arranged at a distance from this assembly area 3.1, the longitudinal axis of which forms the pivot axis S of the hinge lock 1 and thus also the pivot axis of the door leaf 10.1 with respect to the door frame 10.2. The pivot pin 3.2 is connected to the assembly area 3.1 via a connection area 3.3. The assembly area 3.1 has two stiffening ribs 3.31, which can be seen in FIG. 5b and which are aligned with the guide projections 2.15. In this respect, the three locking blocks 4.22 of the bolt 4 encompass the two stiffening ribs 3.31 of the second hinge element 3 in the locking position V and the two guide projections 2.15 of the hinge base 2.1 in the unlocking position E. During a movement between the locking position V and the unlocking position E, the bolt 4 or the bolt section 4.2 either moves between the stiffening ribs 3.31 to secure the hinge pin 3.2 in the hinge pin receptacle 2.17, or between the guide projections 2.15 to release the hinge pin 3.2 in this unlocked position E.

To connect the hinge base 2.1 to the bolt holder 2.2, both elements have corresponding bores, so that the hinge base 2.1 can be connected to the bolt holder 2.2 via a screw connection. The corresponding bores of the bolt 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 section 2.18, which also projects somewhat. These projections create a guide groove behind the corresponding sections 2.18, 2.24, which extends perpendicular to the locking direction R through the first hinge element 1 and which can also be seen in FIG. 6a. In Fig. 6a, the bolt 4 is not shown, but it is the space between the hinge base 2.1 and the bolt holder 2.2 can be clearly seen, in which the bolt 4 is arranged. The corresponding surfaces of the intermediate space are each designed as drive rod sliding surfaces and are labeled 2.16 and 2.25, respectively. The drive rod 6.1, which is not shown in FIG. the functioning of which is described in more detail below.

The drive rod 6.1 is designed as a flat rod and can be moved perpendicular to the locking direction R and thus in the longitudinal direction of the hinge strip 7. The drive rod 6.1 has a total of four S-shaped guide slots 6.11, two of which are arranged in pairs and two of which are used to drive a bolt 4 so that two bolts 4 can be moved back and forth with the drive rod 6.1. The guide elements 4.11 of the bolt 4 guided in the guides 2.11, 2.21 of the bolt base 2.1 are also guided in the guide slots 6.11 of the drive rod 6.1. This becomes clear, for example, on the basis of FIG. 6a. The two guide elements 4.11 facing the hinge base 2.1 and guided in the guide 2.11 also penetrate the two guide slotted links 6.11 of the drive rod 6.1. Each guide element 4.11 is guided in one of the guide slots 6.11. With a linear movement of the drive rod 6.1, the guide elements 4.11 slide in the guide slot 6.11 and therefore move the bolt 4 forwards or backwards in the bolt direction R, depending on the direction in which the drive rod 6.1 is moved.

In order to move the drive rod 6.1 accordingly, 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 is can be seen in the exploded view of FIG. The drive device 6.2 initially has a rotatable actuating element 6.24, which in the exemplary embodiment is designed as a tool actuation, as can also be seen, for example, with reference to FIG. 4 or FIG. 13a. Alternatively, the actuating element 6.24 can also be designed, for example, as a handle actuation, as a knob actuation or as a latch actuation. The actuating element 6.24 is rotatably mounted in the drive housing 6.25, and the drive housing 6.25 is connected to the hinge strip 7 via mounting points 7.6, which can be seen in FIG. 7a. The drive housing 6.25 also serves as a bearing for a pinion 6.22, which rotatably couples to the actuating element 6.24 and accordingly moves along with a rotary movement of the actuating element 6.24. The pinion 6.22 meshes with an actuating rod 6.23 designed as a rack and having several recesses arranged next to one another and, like a linear drive, causes the actuating rod 6.23 to move linearly in the longitudinal direction of the hinge strip 7 when the pinion 6.22 is rotated. To guide the actuating rod 6.23, a linear guide 6.26 is provided, which is also connected to the drive housing 6.25 and therefore cannot be moved. 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 rotatably in the axial direction together with the pinion 6.22 by means of a screw and is also connected to the drive housing 6.25 with the linear guide 6.26.

The actuating rod 6.23 has hook-shaped connection sections at its two ends, via which it can be connected to two drive rods 6.1, that is to say to one on each side. When the actuating rod 6.23 moves via the actuating element 6.24, both drive rods 6.1 are set in motion together. Since every drive Rod 6.1 is coupled via the paired guide links 6.11 each with two bolts 4, all four bolts 4 of the hinge assembly 11 can thus be moved back and forth between the locking position V and the unlocking position E together and in the same direction via the drive device 6.2 will. In a further development, it would also be possible to couple the drive rods 6.1 with further drive rods 6.1 in order to thus also actuate several bolts 4 at the same time.

In FIGS. 12a and 12b, a locking device 6.3 is shown, which is also part of the drive device 6.2. The locking device 6.3 has a movable locking tongue 6.31 which can be rotated back and forth like a fastener. In the blocking position, the blocking tongue 6.31 engages in the recesses of the actuating rod 6.23 that can be seen in FIG. 11 and then blocks a movement of the actuating rod 6.23. Because the actuating rod 6.23 is coupled to the actuating element 6.24, the actuating element 6.24 can no longer be rotated at the same time due to the blocking of the actuating rod 6.23.

The locking device 6.3 can be inserted into the drive housing 6.25 via a connection area 6.32 and can be connected to the drive housing 6.25 via a screw. As can be seen from the various positions of the locking device 6.3 in FIG. 4, the locking device 6.3 can be arranged both below and above the drive housing 6.25. Accordingly, the drive housing 6.25 also has two receptacles into which the locking device 6.3 can be inserted. The entire drive device 6.2, regardless of whether a locking device 6.3 is provided or not, can be designed as a pre-assembled assembly unit that can be assembled as a whole on the hinge strip 7, as will be explained in more detail below with reference to FIGS. 7a to 7f. This assembly unit can also be seen in FIGS. 13a, 13b. As has already been described above, the hinge closures 1, which are arranged in an end region of the door leaf 10.1, are mounted together on a hinge strip 7. This hinge assembly 11 is designed as a preassembled assembly unit and can be connected as a whole to the door leaf 10.1.

In the figures, two different configurations of the hinge assembly 11 are shown, namely in FIGS is hidden between the door leaf 10.1 and the door frame 10.2. In another embodiment, in which the hinge strip is arranged on the outside of the door leaf 10.1, as shown for example in FIGS. 14 to 17, the hinge strip 7 or the hinge assembly 11 can also be seen from the outside . The hinge strips 7 or the hinge assemblies 11 of the two exemplary embodiments differ only slightly from one another with regard to their construction. Basically, it is therefore possible to pre-assemble a basic hinge strip which, depending on whether it is to be used for internal installation on the inside of the door leaf or for external installation on the outside of the door leaf, can be adapted to the respective application with little effort. The internal assembly of the hinge assembly 11 will now first be described with reference to FIGS. 7a to 7f and the sectional views of FIGS. 8 to 10. The configuration of the hinge elements 2, 3 and also the drive device 6.2 described in FIGS. 5a, 5b and 6 can basically be used both for internal installation and for external installation.

According to the illustration in FIG. 7a, the hinge strip 7 has a base element 7.1 which, after assembly, rests on the surface of the door leaf 10.1. Extends perpendicularly from this basic element 7.1 a first leg element 7.2 which, during the internal assembly of the hinge strip 7, rests against a bevel of the door leaf 10.1, as can be seen in FIG. 8b. At the end of the base element 7.1 opposite the first limb element 7.2, a second limb element 7.3 is arranged, which is angled with respect to the base element 7.1 and forms a smaller angle with it than the first limb element 7.2. In the exemplary embodiment, the angle between the second leg element 7.3 and the base element 7.1 is approximately 60 degrees. Furthermore, the hinge strip 7 has several mounting points 7.4, each of which is used to mount a hinge lock 1. the

Mounting points 7.4 each have two mounting bolts 7.41 which extend perpendicular to the base element 7.1 and are firmly connected to the base element 7.1. The hinge locks 1 or the hinge base 2.1 and the bolt holder 2.2 can be connected both to one another and to the hinge strip 7 via these mounting bolts 7.1. Furthermore, the mounting points 7.4 each have a mounting recess 7.42 which extends both through the base element 7.1 and through the first leg element 7.2, as can be seen in the representations of FIGS. 7a to 7e.

During the assembly of a hinge lock 7, the hinge base 2.1 is first inserted into the assembly recess 7.42 so that the assembly bolts 7.41 penetrate the bores provided in the hinge base 2.1. Due to the size of the mounting recesses 7.42 adapted to the hinge base 2.1 and due to the position of the mounting bolts 7.41, the hinge base 2.1 can only be inserted into the hinge strip 7 in a predefined position. The rear of the mounting section 2.18 facing the pivot pin receptacle 2.17 then rests on the inside of the base element 7.1 of the hinge strip 7, and the pivot pin receptacle 2.17 protrudes opposite the hinge strip 7, as can also be seen, for example, in FIGS. 8a and 8b. After the assembly of the hinge base 2.1, the drive rod 6.1 is inserted into the hinge strip 7 so that it extends parallel to the base element 7.1. Due to the drive rod sliding surface 2.16, which is set back from the assembly section 2.8, the drive rod 6.1 can be placed against the corresponding edge of the hinge base 2.1, so that the guides 2.11 lie below the guide slots 6.11 and, due to the overlap, an essentially circular passage through the drive rod 6.1 and the hinge base 2.1 results.

In a next step, the bolt 4 is then inserted into the hinge base 2.1, as can be seen in FIG. 7c. Two of the total of four guide elements 4.11 then extend through the two parallel guide slots 6.11 of the drive rod 6.1 into the guides 2.11 of the hinge base 2.1. The bolt section 4.2 of the bolt 4 points in the direction of the pivot pin receptacle 2.17. The bolt 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 bolt holder 2.2. The bolt holder 2.2 then engages around the bolt 4 and secures it against unintentional movement. The guide elements 4.11 of the bolt 4 extend into the guides 2.21 of the bolt holder 2.2, and the bolt 4 can only move linearly in the bolt direction R. To move the bolt 4, the drive rod 6.1 can then be moved perpendicular to the bolt direction R, as has already been described above. In a final step, the bolt holder 2.2 and thus also the bolt 4 and the hinge base 2.1 are fastened to the hinge strip 7 by nuts that can be screwed onto the assembly bolts 7.41, as can be seen in FIG. 7d. Furthermore, it can also be seen that the drive rod 7 is connected with two hinge locks 1 or with two bolts 4 or that the guide elements 4.11 of two bolts 4 are in each case in the two End areas arranged guide links 6.11 of the guide rod 6.1 are guided.

After the first hinge element 2 and the drive rods 6.1 for moving the bolt 4 have been installed in the hinge strip 7, the drive device 6.2 can be installed, via which the drive rods 6.1 can be moved. As has already been described above, the drive device 6.2 is designed as a preassembled assembly unit so that it can be assembled as a whole in the hinge strip 7. The hinge strip 7 has a mounting point 7.6 for the drive device 6.2, which has appropriately aligned mounting bolts 7.61 and corresponding recesses so 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 locking device 6.3 arranged above the drive housing 6.25 and for a locking device 6.3 arranged below 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.

After the drive device 6.2 has been installed, the hook-shaped end-side connecting sections of the actuating rod 6.23 engage the correspondingly configured sections of the drive rod 6.1, so that the actuating rod 6.23 is coupled to two drive rods 6.1 via its two end regions. The actuating rod 6.23 designed as a flat rod is arranged parallel to the first leg element 7.2 and thus also perpendicular to the drive rod 6.1, which is also designed as a flat rod. All four hinge locks 1 can then be operated jointly and simultaneously via the drive device 6.2. When the hinge strip 7 has been appropriately equipped with the hinge locks 1 and the drive device 6.2, this hinge assembly 11 be arranged as a pre-assembled assembly unit on the inside of a door leaf 10.1. According to FIG. 3, assembly bolts 10.4 can be arranged on the inside of the door leaf, via which the hinge strip 7 can then be screwed onto the door leaf 10.1.

In FIG. 3 it can be seen that the second hinge elements 3 have also already been connected to the first hinge elements 2. To do this, the latches 4 must be moved into the unlocked position E, and the second hinge elements 3 can then be pushed into the first hinge elements 2 so that the pivot pins 3.2 of the second hinge elements 3 are then in the pivot pin receptacles 2.17 of the hinge base 2.1. The bolts 4 are then moved back into the locking position V in order to secure the pivot bolts 3.2 between bolt 4 and pivot bolt receptacle 2.7. The door leaf 10.1 can then be attached to the door frame 10.2 by attaching the second hinge elements 3 to the latter. Alternatively, the second hinge elements 3 can also be arranged first on the door frame 10.2 and the door leaf

10.1 or the corresponding hinge bases 2.1 are slipped onto the second hinge elements 3.

An end region of the door leaf 10.1 is shown in a closed position in FIGS. 8a and 8b. The door frame 10.2 has a shoulder, at the end of which a seal 10.5 is arranged, which is from the door leaf

10.1 is compressed in the closed position. Furthermore, the shoulder of the door frame extending into the free frame cross section has

10.2 has an assembly area 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 shown in FIG. 7f is arranged on the inside of the door leaf 10.1 facing the door frame 10.2. 8a corresponds to a sectional view through the bolt 4. Accordingly, only part of the base element 7.1 and the second is angled Leg element 7.3 of the hinge strip 7 can be seen. The bolt 4 is in the locking position V, so that it moves the pivot bolt

3.2 secures in the pivot pin receptacle 2.17 and no translational movements 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 FIG. 8a as a flat element, and this is moved to move the bolt 4 in the viewing direction, that is, perpendicular to the plane of the sheet. The free space into which the bolt 4 is moved when transferring from the locking position V to the unlocking position E can also be clearly seen. In the background, the drive device 6.2 can be seen, or the screw via which the actuating element 6.24 and the pinion 6.22 are secured in the axial direction on the drive housing 6.25.

In FIG. 8b, the entire hinge strip 7, that is to say also the first leg element 7.2, can be seen, which is located on one in the direction of the door frame

10.2 facing edge of the door leaf 10.1 is applied. Since the hinge element 1 itself is not shown in a sectional view in the view according to FIG. 8b, the bolt 4 received between the hinge base 2.1 and the bolt holder 2.2 in the interior of the first hinge element 2 cannot be seen. However, both the mounting bolt 10.4, via which the hinge assembly 11 or the hinge strip 7 is arranged on the inside of the door leaf 10.1, as well as the mounting bolt 7.41, via which the hinge base 2.1 and the bolt holder 2.2 with the hinge strip can be seen 7 are connected.

The illustration in FIG. 9 basically corresponds to the view in FIG Fig. 10 shown left pivot axis S can be pivoted. The guide elements 4.1 of the bolt 4 are located in the end area of the S-shaped guide slot 6.11, so that in this position the bolt 4 is also no longer in the receiving area 3.4 between the pivot pin 3.2 and the assembly area 3.1 of the second hinge element 3. In FIG. 10, the opposite end region of the door leaf 10.1 is then shown in a pivoted position. The hinge elements 1 of the hinge assembly 11 arranged in this end area are in the locking position V, so that a pivoting movement of the door leaf 10.1 is possible.

The second embodiment shown in FIGS. 14 to 17 relates to a hinge strip 7 or a hinge assembly 11 which is not arranged on the inside of the door leaf 10.1, but on the outside of the door leaf 10.1. Since the hinge strips 7 are correspondingly visible from the outside, they also have a hinge strip cover 7.7 as well as closing elements 7.8 at the upper and lower ends in addition to the configuration described above. The differences between the hinge elements 2, 3 and the first embodiment are explained in greater detail below with reference to FIGS. 19a to 21.

In FIGS. 18a to 18e, the assembly of the individual components of the hinge assembly 11 is shown analogously to the representations in FIGS. 7a to 7f. In order to recognize both end areas of the hinge strip 7, the middle area of the hinge strip 7 is not shown in FIGS. 18d and 18e. However, since the drive device 6.2 located in this area is identical to the drive device 6.2, which has already been described above with regard to the hinge assembly 11 suitable for internal assembly, the above description is referred to with regard to the design and the connection of the drive device 6.2 - grasslands. In the case of the hinge assembly 11 for external assembly, the hinge strip 7 is first pushed into the hinge strip cover 7.7, as is the case this can be seen in FIG. 18a. Since the hinge strip 7 is designed identically both for internal installation and for external installation, reference is also made to the above description in this regard. The assembly of the hinge base 2.1 and the drive rod 6.1 shown in FIGS. 18b and 18c is also identical, as was already described above with regard to FIGS. 7a and 7b. The assembly of the bolt 4 and the bolt holder 2.2 is therefore also not shown in FIGS. 18a to 18e. In contrast to the hinge assembly 11 for internal assembly, after the assembly of the first hinge element 2 in the hinge assembly 11 for external assembly, the hinge strip cover 7.7 is connected to the hinge strip 7. For this purpose, a mounting element 7.5 designed as a pressure piece is used, which is shown in the illustration in FIG. 18d. The pressure piece is supported against the hinge strip 7 and has two projections designed in the manner of wings which, in the connected position, engage behind or in corresponding notches in the hinge strip cover 7.7. The hinge strip cover 7.7 is thus tensioned against the hinge strip 7 by the pressure piece. For assembly, the pressure piece is first introduced into the hinge strip 7 and then rotated through 90 ° so that the projections engage under the hinge strip cover 7.7 or in the corresponding receptacle. Due to the residual material tension of the pressure piece, the hinge strip cover 7.7 is then frictionally connected to the hinge strip 7, so that, for example, no externally visible screws have to be screwed into the hinge strip cover 7.7. In a last step, the ends of the hinge strip 7 or the hinge strip cover 7.7 are then closed by closing elements 7.8, as can be seen in FIG. 18e. In FIGS. 19a and 19b, analogous to FIGS. 8a, 8b, the hinge assembly 1 arranged on the outside of the door leaf 10.1 is shown. An essential difference is that the first hinge element 3 is longer in external assembly than in internal assembly. This goes hand in hand with the fact that the second hinge element 2 not only has to span the distance between the door frame 10.2 and the door leaf 10.1, but also the height of the hinge strip 7. This then also results in a pivot axis S that is further away from the door frame 10.2. Nevertheless, during external assembly, the door leaf 10.1 can come closer to the door frame 10.2 as no or less space is required there for the hinge assembly 11, as is clear when comparing FIGS. 19a and 8a. In addition, there is also a larger free door frame cross-section, since only sufficient space is required in the door frame 10.2 to mount the second hinge element 3, but not additionally for the first hinge element 2 or the hinge strip 7 and the drive mechanism 6.2 .

In FIG. 19b, the assembly element 7.5 can be seen as well as the projections which grip behind the hinge strip cover 7.7 and which thereby press the hinge strip cover 7.7 against the hinge strip 7. With regard to FIGS. 20 and 21, reference is made to the description of FIGS. 9 and 10.

In order to fasten the hinge assembly 11 to the outside of the door leaf 10.1, mounting bolts 10.3 are provided according to FIG. 16, which are designed as Allen screws. These are screwed from the inside through the door leaf 10.1 and then into the hinge strip 7, so that no screws can be seen from the outside. Alternatively, it is also possible to screw the screws into the mounting element 7.5. Overall, the hinge assemblies 11 for internal assembly and for external assembly differ only slightly from one another, so that simple retrofitting or simple adaptation of the preassembled components is possible.
