[0041] FIG. 9 shows a schematic view of a door with four hinge closures.

[0042] Hinge closures 1 comprise for the most part two hinge elements 2, 3 which are coupled with one another so as to be pivotable and releasable and serve, on the one hand, as a hinge so that a door 4, for example, can be opened or closed, on the other hand, however, also as a closure in order to lock a door 4.

DETAILED DESCRIPTION

[0043] The term “door” is to be broadly understood in the sense of said invention as pivotable closing elements which are movable back and forth between an open position and a closed position. Along with normal doors in the actual sense, said term consequently also includes, for example, flaps, hatches, covers, windows and the like.

[0044] The arrangement of four hinge closures 1 on a door 4 and the various possibilities for opening the door are now to be described below by way of FIG. 9 before the more precise design of the hinge closures 1 is then discussed in more detail.

[0045] FIG. 9 shows the outside of a door 4 with four hinge closures 1 which are arranged on the door 4. The frame of the door 4, on which each of the second hinge elements 3 of the hinge closures 1 are arranged, is not also shown in FIG. 9.

[0046] When all four hinge closures 1 are situated in the locked position, the door 4 is fixed in relation to the frame and cannot be opened. The hinge closures 1 then act correspondingly as closures which lock the door 4.

[0047] In order to open the door 4, both hinge closures 1, which are arranged on one side of the door 4, have to be unlocked. If, for example, the two right-hand hinge closures 1 are unlocked, the door 4 can thus be pivoted about the two hinge closures 1 which are on the other side and are still in the locked position. In said position, the two right-hand hinge closures 1 then act as hinges. In addition, all four hinge closures 1 can also be unlocked so that the door 4 can be removed in its entirety from the frame.

[0048] In order to transfer the hinge closures 1 from the locked position into the unlocked position, they each comprise an actuating device 6, which is shown, for example, in FIGS. 1 and 2. As the hinge closures 1 according to the representation in FIG. 9, however, are all arranged on the outside of the door 4, the corresponding actuating devices 6 can also only be actuated from the outside of the door 4. It is thus not possible to unlock the hinge closures 1 from the interior using the actuating devices 6 and then to open the door 4. However, in order then, nevertheless, also to be able to unlock the hinge closures 1 from the interior in an emergency situation, they each comprise an emergency unlocking device 8 which is actuatable from the interior in the event of an emergency. Said emergency unlocking device 8 is described in more detail below with regard to FIGS. 1 to 7.

[0049] In the representation in FIGS. 1a and 1b, the hinge closure 1 is shown from two different sides on a door 4 in the mounted state. The first hinge element 2, in this case, is arranged on the door 4 and the second hinge element 3 is arranged on a door frame which is not shown in the figures. The side of the door 4, on which the hinge element 2 is arranged, corresponds in the exemplary embodiment to the outside of the door 4, the opposite side of the door 4 corresponding to the inside.

[0050] An exploded representation of the hinge closure 1 is shown in FIG. 2, the two hinge elements 2, 3 being shown separately from one another. In addition, it is also possible to see the emergency unlocking device 8 which is mounted from the inside of the door 4 and, in the mounted state, protrudes in part beyond the inside of the door 4, as can also be seen in FIG. 1b.

[0051] FIGS. 3a to c correspond to FIGS. 1a, b and 2, the hinge elements 2, 3 not being shown as well. The emergency unlocking device 8 is arranged in the door 4 via a guide element 9 in the form of a bearing bush. Said guide element 9 passes through the door 4 and is connected to said door by means of screws. On the inside of the door 4, the guide element comprises a rosette-like projection which, in the mounted state, rests on the inside of the door 4. In the mounted position, the emergency unlocking device 8 or an effective region 8.1 of the emergency unlocking device 8 projects through the door 4 so that, in the mounted state, it extends into the first hinge element 2. More detailed explanation is now to be provided below by way of the further figures, in particular by way of the various positions shown in FIGS. 5 to 7. FIGS. 5a, 6a and 7a, in this case, each show a first sectional view of the hinge closure 1, FIGS. 5b, 6b and 7b show a second sectional view perpendicular to the first sectional view.

[0052] In the representation in FIG. 5b, the hinge closure 1 is shown in a locked and blocked position. In said position, the actuating device 6 is pivoted into the contour of the hinge closure 1 and the emergency unlocking device 8 is situated in the basic position. The locking device 7 is situated in the locked position and holds the bolt 5, which is arranged on the second hinge element 3, in the receiving means 12 arranged on the first hinge element 2. In said position, the first hinge element 2 can be pivoted about the longitudinal axis of the bolt 5 and the door 4 can be opened insofar as it is not still secured in another manner, cf. FIG. 8.

[0053] In addition, the hinge closure 1 according to FIG. 5 is situated in the blocked position. In said position, the actuating device 6 is blocked and cannot be pivoted about the actuating rotational axis B. The actuating device 6 comprises a closing cylinder 10.1 which, together with the blocking element 10.2, forms a blocking device 10. In the position shown in FIG. 5b, the closing cylinder 10.1 is in engagement with the blocking element 10.2 which is arranged on the first hinge element 2, so that the actuating device 6 cannot be pivoted. The locking device 7, in said position, abuts against a corresponding coupling edge 6.1 of the actuating device 6 via a coupling edge 7.2 and cannot be moved toward the actuating device 6 either on account of the blocking action of the blocking device 10.

[0054] If the two hinge elements 2,3 are then to be separated from one another in an emergency situation so that the door 4 can be opened, first of all the blocking device 10 has to be unblocked. The emergency unlocking device 8 comprises for this purpose a first effective contour 8.2 which is designed as a recess and can be seen in the enlarged representations in FIG. 4. In the locked and blocked position according to FIG. 5, said first effective contour 8.2 abuts against the blocking element 10.2. If the emergency unlocking device 8 is then actuated in the emergency actuation direction N, that is to say is moved upward according to FIG. 5b, the first effective contour 8.2 thus first of all unblocks the blocking element 10.2. Said blocking element moves out of engagement with the closing cylinder 10.1 on account of the movement of the emergency unlocking device 8 so that the actuating device 6 is then unblocked. Said position, which is still locked but already unblocked, is shown in FIGS. 6a, b. As can be seen, the emergency unlocking device 8 has already been displaced a little in the emergency actuation direction N.

[0055] If the emergency unlocking device 8 is moved even further in the emergency actuation direction N, the second effective contour 8.3, which is designed in the manner of a run-up slope, moves into abutment with the coupling contour 7.1 of the locking device 7. If the emergency unlocking device 8 is then moved further in the emergency actuation direction N, the locking device 7 is thus moved out of its locked position shown in FIG. 6 into the unlocked position shown in FIG. 7. In said position, the bolt 5 is no longer secured in the receiving means 12 so that the two hinge elements 2,3 are able to be separated from one another.

[0056] The locking device 7 is pretensioned in the direction of the locked position via a compression spring 13. In the event of emergency actuation, the locking device 7 is moved in the opposite direction to the spring force. On account of the contact between the coupling edge 7.2 of the locking device 7 and the coupling edge 6.1, the unlocking movement of the locking device 7 results in the actuating device 6 being rotated about the actuating rotational axis B and consequently being pivoted out of the contour of the hinge closure 1.

[0057] As can be seen in the basic position according to the representation in FIG. 5, the emergency unlocking device 8 additionally has a groove 8.5 in which a sealing element 11 in the form of an O-ring is received. The sealing element 11 seals the emergency unlocking device 8 in relation to the guide element 9 so that a gas exchange cannot take place between the interior and the exterior of the door 4.

[0058] In addition, the emergency unlocking device 8 is secured in the basic position against being pulled out of the guide element 9 or of the door 4. The emergency unlocking device 8 comprises for this purpose a latching edge 8.6 which, in the basic position, abuts against a projection 9.1 of the guide element 9, which projection is designed as a clip, so that it is not possible to pull out the emergency unlocking device 8.

[0059] How the emergency unlocking device 8 interacts with the closing element 10.2 for unblocking and with the closure element 7 for unlocking is to be described again below by way of FIGS. 8a and 8b. Certainly with regard to the structural design thereof, the emergency unlocking device 8 shown in FIGS. 8a and 8b comprises slight differences to the locking devices 8 shown in the remaining figures, however, these do not affect the method of operation, which is why the various emergency unlocking devices 8 are mutually interchangeable.

[0060] In FIGS. 8a and 8b, the emergency unlocking device 8 is shown analogously to that shown in each case in the basic position in FIGS. 5a and 5b. If the emergency unlocking device 8 is moved in the emergency actuation direction N for emergency unlocking, first of all the first effective contour 8.2 comes in contact with the blocking element 10.2. Said blocking element comprises a bevel 10.23 which interacts with the first effective contour 8.2 in the manner of a run-on slope in the case of a movement of the emergency unlocking device 8. The blocking element 10.2 is mounted so as to be rotatable and comprises a bore 10.22 for receiving a bolt or another bearing element. In addition, the blocking element 10.2 comprises a spring 10.23, via which it is pretensioned in the blocking direction.

[0061] If the emergency unlocking device 8 is moved in the emergency actuation direction N, the first effective contour 8.2 comes into contact with the bevel 10.23, which results in the blocking element 10.2 being pivoted in opposition to the force of the spring 10.23 about an axis which extends through the bore 10.22. Said pivoting movement then results in the blocking device 10 being unblocked.

[0062] A further movement of the emergency unlocking devices 8 results in the second effective contour 8.3 coming into contact with the coupling contour 7.1 and the locking device 7 being transferred in opposition to the force of the spring 13 into the unlocked position, as has also been described above with regard to FIG. 7.

[0063] The more precise design of the locking device 7 is shown in FIG. 8b. It can be seen that the coupling contour 7.1 is arranged on the side of the locking device 7 which is situated opposite the emergency unlocking device 8 so that the emergency unlocking device 8 moves into the locking device 7 during unlocking and then the second effective contour 8.3 strikes against the coupling region 7.2 and, with a further movement, unlocks the locking device 7. In the unlocked position, the tip of the second effective contour projects beyond the locking device 7, as can also be seen in FIG. 7a.
