Description

The present invention relates to a hinge with a first hinge element for arrangement on a closing element and a second hinge element for arrangement on a frame, which are connected to one another in an articulated manner about a hinge axis. A further subject of the invention is a method for adjusting a hinge with a first hinge element for arrangement on a closing element and a second hinge element for arrangement on a frame, which are connected to one another in an articulated manner about a hinge axis.

Hinges are used for lockable openings such as doors, hatches and windows. There they enable an articulated arrangement of locking elements, such as door leaves, hatch bulkheads, flaps, window sashes or covers, on a frame surrounding the opening. The hinge guides the movement of the locking element in such a way that the locking element can be easily moved into an open position to release the opening and into a closed position to close the opening.

In order to enable this articulated arrangement of the locking element on the frame, hinges have two hinge elements. A first hinge element is arranged on the locking element and a second hinge element on the frame. Both locking elements are connected to one another in an articulated manner around a hinge axis. In this way, the hinge connects the frame and the locking element to one another and at the same time enables an articulated movement of the locking element relative to the frame.

In order for the locking element to close the opening evenly and also to compress sealing elements arranged between the frame and the locking element, such as sealing profiles or sealing beads, to seal it, the hinge often needs to be aligned in order to compensate for manufacturing tolerances, wear effects and the like that occur in practice. The aim of this alignment is to position the hinge and thus the hinge axis in such a way that the locking element is at a uniform distance from the frame in the closed position and at the same time exerts a uniform contact pressure on the sealing elements.

Typically, this alignment is achieved during assembly by arranging spacers, for example in the form of shims or similar, between the hinge elements and the frame and/or the locking element. In practice, however, this alignment often proves to be very complex, since the respective hinge element has to be attached a spacer from the frame or the locking element and then reattached. The spacers only allow adjustment in discrete steps, which depend on the thickness of the spacers available, which means that a uniform distance and contact pressure can only be achieved to a limited extent. In addition, subsequent adjustments to the alignment of the hinge, such as those required due to wear effects, the use of other sealing elements or distortion of the frame and/or the locking element, are only possible to a limited extent and at great expense. In these cases too, the hinge can only be removed by a laborious loosening of the connection to the frame or the

Adjust locking element.

The US 1325221 A and the EP3147438A1 reveal adjustable hinges.

The object of the present invention is therefore to provide a hinge which enables simpler and more precise alignment. This object is achieved in a hinge of the type mentioned at the outset by the features of claim 1.

The adjusting element makes it easy to adjust the distance between the hinge axis and one of the two hinge elements and thus to the frame and/or the locking element. The alignment of the hinge can be infinitely adjusted regardless of the thickness of the available spacers. It is not necessary to detach the hinge element from the frame and/or the locking element, but this is still possible. A uniform distance between the locking element in the closed position and the frame and thus a uniformly applied contact pressure on the sealing elements can be achieved easily and with high precision by adjusting the distance between the hinge axis and the frame.

Preferably, the adjusting element is movable transversely to the hinge element.

By moving the adjusting element transversely to the hinge element, the distance of the hinge axis can be adjusted in a particularly advantageous manner.

According to the invention, the hinge axis is arranged on an axis support arranged between the two hinge elements. An axis support allows the hinge axis to be arranged so that it can move between the hinge elements in a structurally simple manner. The axis support can also enable the hinge axis to be replaced.

In this context, it is particularly advantageous that the axle carrier and the hinge axis can be adjusted together using the adjusting element. This allows a structurally simple, compact design to be achieved. The axle carrier can serve as a support element for the hinge axis.

Furthermore, a guide for guiding the adjusting movements of the axle carrier is provided according to the invention.

The axle carrier can be guided in a structurally simple manner using a guide. The play of the axle carrier transverse to the direction of the adjustment movements can be reduced, in particular suppressed, by the guide.

According to the invention, the guide is formed from a guide area on the axle carrier side and a guide area on the hinge element side, which abut one another in the manner of a sliding guide. In this case, surfaces of the two guide areas that abut one another can enable a positive-locking guide up to one axial degree of freedom. The guide areas can be designed to complement one another. In a particularly advantageous manner, the guide areas can be positively locked, in particular along several axes transverse to the direction of the adjustment movements of the axle carrier. The axle carrier can be prevented from coming out of the guide in a simple manner. The guide areas can alternatively or additionally transmit hinge forces acting on the hinge from the outside, for example via the locking element. Loading the actuating element with these hinge forces, in particular transverse to the direction of the actuating movement of the actuating element and/or the axle carrier, can be avoided and the risk of damage to the actuating element can be reduced.

In a further development of the invention, the axle carrier and the hinge element are formed complementarily to one another in the manner of plug-in connection elements. The complementary shape can enable a simple and reliable connection of the axle carrier to the hinge element. The actuating movement can be guided in a structurally simple manner by the complementary shape of adjacent areas of the stretch connection elements. The axle carrier can completely or partially encompass sides of the hinge element, in particular opposite sides, or can be encompassed by the hinge element.

It is also advantageous if the axle carrier has a hinge pin for the articulated arrangement of a hinge eye of the other of the two hinge elements. The hinge pin can provide a bearing for the arrangement of the hinge eye in the manner of a rotary joint. It can run coaxially to the hinge axis. By means of a hinge eye that completely or partially surrounds the hinge pin, the hinge element can be arranged on the axle carrier in a structurally simple manner.

In this context, it is particularly advantageous if the joint eye of the hinge element has a locking mechanism by means of which the joint eye can be released from the hinge pin or locked to it. The locking mechanism enables the hinge element be detached from the other elements of the hinge or connected to them. In the detached state, the two hinge elements can be separated from each other. The locking mechanism can be movable transversely to the hinge pin and/or engage behind the hinge pin to lock the hinge eye, preferably on the side facing away from the hinge eye. The hinge can therefore have a dual function. It can be used both as a joint between the locking element and the frame and as a lock to lock the locking element to the frame. In this respect, the hinge can be a hinge designed as a locking hinge. In this case, it is advantageous to arrange two locking hinges on both sides of the locking element, as is the case in the EN 10 2017 129 427 is described. The locking mechanism can be operated via an actuating device to release or lock the joint eye.

Preferably, two adjusting elements are provided and arranged on both sides of the hinge pin. Two adjusting elements allow an inclination relative to the hinge element. The hinge axis can be inclined relative to the hinge element by setting different distances. The adjustable inclination of the hinge axis can be used to compensate for distortion of the frame and/or the locking element. An arrangement of the adjusting elements on both sides of the hinge pin allows a reliable and stable adjustment of the distance between the hinge axis, which runs coaxially to the hinge pin, and the hinge element, in a way that prevents unwanted movements. The two adjusting elements can support the hinge pin in the manner of a two-point support along the adjustment direction.

According to the invention, the adjusting element comprises a thread for connection to a counter thread of the hinge element and a groove for rotationally movable but axially fixed arrangement on the axle carrier. The thread of the adjusting element can be an external thread with a counter thread of the hinge element designed as an internal thread or as an internal thread with a counter thread of the hinge element designed as an external thread. The distance of the hinge axis from the hinge element can be adjusted continuously by rotating the thread relative to the counter thread. The rotary movement of the adjusting element can be converted into a linear adjusting movement of the axle carrier. The adjusting element can be designed as a screw with a head diametrically opposite the thread. The head preferably comprises a drive area, in particular in the form of a hexagon socket, hexagon socket, hexagon socket, slot or Phillips slot, for driving the adjusting element by an appropriately designed drive device, such as a manual screwdriver or a drill driver. The adjusting element can be mounted on the axle carrier so that it can rotate freely in the circumferential direction thanks to the groove.

The groove is arranged between the thread and the head of the adjusting element. It can be designed in the manner of a circumferential groove with a smaller radial diameter than the thread and/or the head of the adjusting element.

According to the invention, the axle carrier comprises a bearing opening with a bearing area for transmitting thrust and tensile forces and a larger insertion area for inserting the at least one actuating element. The bearing area can have an inner diameter which is smaller than the outer diameter of the thread and/or the head of the actuating element. The locking element is prevented from escaping from the bearing area along the axial direction by means of a positive locking. The bearing area is designed in such a way that it essentially receives the groove of the actuating element in a positive locking manner. By means of an essentially positive locking bearing of the actuating element, it can be moved along its axial direction. Direction. The pushing and pulling forces can be easily transferred from the adjusting element to the axle carrier to adjust the distance to the hinge element. The insertion area can have an inner diameter which is larger than the outer diameter of the thread and/or the head of the adjusting element. The adjusting element can be inserted into the larger insertion area of the bearing opening with the smaller thread-side and/or head-side end first. To transfer the adjusting element from the insertion area to the bearing area of the bearing opening, the adjusting element and/or the axle carrier can be moved essentially transversely to the adjusting direction. The movement of the adjusting element can preferably take place when the adjusting element is not yet arranged on the hinge element. The movement of the axle carrier can preferably take place when the adjusting element is already arranged on the hinge element. To transfer from the bearing area to the insertion area, the movement can take place in the opposite direction. The bearing area and the insertion area can form two diametrically opposite ends of the bearing opening.

According to the invention, the bearing area and the insertion area form a keyhole-shaped bearing opening. A keyhole-shaped bearing opening, in which the bearing area and the insertion area are essentially round and connected to one another by an elongated hole, enables a structurally simple transfer of the actuating element between the insertion area and the bearing area. Alternatively, but not according to the invention, the bearing area and the insertion area can also form a bearing opening of a different geometric shape, for example a triangular, trapezoidal, kite or L-shaped bearing opening, in particular with rounded corner areas.

Preferably, the bearing areas of at least two bearing openings face each other. In a hinge with several adjusting elements The adjusting elements can protect each other against escaping from the storage area by arranging the bearing openings with the bearing areas facing each other. This is because the adjusting elements would have to be transferred from the storage area to the insertion area in order to be able to escape. Due to the arrangement of the bearing areas facing each other, the adjusting elements would have to move in opposite directions, which is not possible, especially with adjusting elements arranged on the hinge element. In addition, a movement of the axle carrier that would transfer the adjusting elements to the insertion areas can also be prevented. This is because the axle carrier would have to be moved in two opposite directions at the same time.

In a method of the type mentioned at the outset, a method according to claim 8 is proposed to solve the above-mentioned problem. This results in the advantages already explained in connection with the hinge. The distance of the hinge axis to one of the two hinge elements and thus to the frame and/or the locking element can be easily adjusted using the adjusting element. The alignment of the hinge can be carried out continuously, regardless of the thickness of the available spacers. Detaching the hinge element from the frame and/or the locking element is not necessary, but is also possible. A uniform distance of the locking element in the closed position from the frame and a uniformly applied contact pressure on the sealing elements can be achieved by adjusting the distance of the hinge axis.

The features described in connection with the hinge according to the invention can also be used in the method. This results in the described advantages.

Hinges 1 have two hinge elements 2, 3 which are pivotally connected to one another and which allow a closing element, such as a door leaf, hatch bulkhead, window leaf, cover or flap, to be pivoted relative to a frame. For this purpose, a hinge element 2 is arranged on the closing element and a hinge element 3 on the frame. An opening surrounded by the frame, which can be a door, hatch or window, for example, can be closed or opened in a simple manner.

In order to enable the opening to be closed evenly by the closing element and to compress a sealing element arranged between the frame and the closing element, such as a sealing lip or sealing bead, for sealing, the hinge 1 must be aligned. The hinge 1 according to the invention enables simple and precise alignment. Two possible embodiments of this hinge 1 will be discussed below. will be discussed in more detail below using the figures. According to the invention, the frame does not have to be a separate element. The frame can also be formed by the edge of a wall surrounding the opening or something similar.

The Fig. 1 and Fig. 2 different perspective views of a first embodiment of the hinge 1. The hinge element 2 can be arranged on a locking element via connecting means on its underside (not shown). The hinge element 3 is arranged on the frame of the opening (not shown). However, it is also possible to arrange one of the two or both hinge elements 2, 3 partially or completely within the locking element or the frame. Likewise, the hinge element 2 can be arranged on the frame and the hinge element 3 on or in the locking element.

The box-shaped hinge element 2 and the elongated hinge element 3 are preferably made of injection-molded plastic, but may also have metal elements, in particular in the area of the hinge axis A, or may be made entirely of metal.

The hinge 1 shown is designed in the manner of a locking hinge. It has an actuating device 6 arranged on the hinge element 2, the function of which will be described in more detail below.

The two hinge elements 2, 3 are connected to one another via a hinge axis A in such a way that they can be pivoted against one another. The hinge axis A runs essentially parallel to the plane of the locking element (not shown). In order to adjust the distance between the hinge axis A and the hinge element 3, the hinge 1 shown has two adjusting elements 5, although a single Adjusting element 5 would be sufficient for adjusting the distance of the hinge axis A according to the invention.

The control elements 5 are shown in Fig. 1 and Fig. 2 shown spaced apart from the hinge elements 2, 3. However, when the hinge 1 is assembled, the adjusting elements 5 are inserted into bearing openings 4.1 of an axle support 4 arranged between the two hinge elements 2, 3. This axle support 4 carries the hinge axis A. By changing the distance of the axle support 4 from the hinge element 3, the distance of the hinge axis A from the hinge element 3 is simultaneously adjusted in a structurally simple manner.

As in Fig.1 As can be seen, the cylindrical actuating element 5 has a thread 5.1, which serves to connect the actuating element 5 to the hinge element 3. On the side diametrically opposite the thread 5.1, the actuating element 5 has a head 5.3, which forms the end of the actuating element 5. The head 5.3 has a larger radius than the thread 5.1, but can also have the same radius as the thread 5.1. In addition, the head 5.3 comprises a drive area 5.4, which is designed in the manner of a hexagon socket. Alternatively, the drive area 5.4 can be designed in the form of an external hexagon, hexagon socket, slot or Phillips slot. The actuating element 5 is coupled to a drive device (not shown), such as a screwdriver or a drill driver, to drive the actuating movement via this drive area 5.4. The actuating element 5 has an essentially helical geometry overall.

For the arrangement on the axle carrier 4, the adjusting element 5 has a circumferential taper with a groove 5.2. The groove 5.2 is limited by the thread 5.1 and the head 5.3, but can also have a distance to these. The groove 5.2 enables a rotatable but axially fixed arrangement on the axle carrier 4. For this purpose, the groove 5.2 is designed in the manner of a radius change that suddenly jumps back inwards. This enables a positive mounting of the groove 5.2 in the bearing opening 4.1. Thrust and tensile forces can be transferred from the adjusting element 5 to the axle carrier 4 to adjust the distance from the hinge element 3.

The following is the Fig.1 illustrated hinge element 3 based on the illustration in Fig.3 described in more detail. It has a bar-shaped geometry with a height that is essentially smaller than its length. Two projections 3.02 protrude from the side 3.01 facing the axle carrier 4. These each have a counter thread 3.1, which cooperates to connect the adjusting element 5 with its thread 5.1. The counter thread 3.1 is designed as an internal thread of a threaded hole.

In addition to the projections 3.02, the hinge element 3 has a countersunk hole 3.5 in which a connecting recess 3.2 is located. This connecting recess 3.2 serves to arrange the hinge element 3 on the frame, with a connecting means (not shown), such as a screw or a rivet, being passed through the connecting recess 3.2. The hinge element 3 can be connected directly to the frame in this way or connected to one or more other elements for arrangement on the frame. The countersunk hole 3.5 ensures that the connecting means does not protrude from the side 3.01 of the hinge element 3 and does not hinder the adjustment movement of the axle carrier 4.

A recess 3.3 arranged between the counter threads 3.1 allows a free rotational movement of the hinge element 2 arranged around the hinge axis A in the assembled state of the hinge 1. A Collision of the areas of the hinge element 2 arranged around the hinge axis A of the axle support 4 with the hinge element 3 is prevented by the recess 3.3. The hinge element 2 is provided with sufficient space for movement even if the distance between the hinge axis A and the hinge element 3 is small.

The hinge element 3 also has a guide area 3.4 for guiding the adjustment movement of the axle carrier 4. This interacts with a guide area 4.4 of the Fig.4 shown axle carrier 4. Together, both guide areas 3.4, 4.4 form a guide for guiding the actuating movement of the axle carrier 4. To do this, they rest against each other like a sliding guide with the contact surfaces 3.41, 4.41. The two-part guide area 3.4 is designed to be complementary to the guide area 4.4 and accommodates it, which enables the movement of the axle carrier 4 to be guided in a form-fitting manner. Hinge forces acting transversely to the actuating element 5, i.e. essentially parallel to side 3.01, are transferred from the axle carrier 4 to the hinge element 3 by the guide 3.4, 4.4. This prevents the actuating element 5 from being subjected to these hinge forces, which is disadvantageous in terms of connection technology. The actuating elements 5 are therefore outside the force flow.

The hinge element 3 and the axle carrier 4 are designed by the guide 3.4, 4.4 in the manner of interacting plug-in connection elements. The axle carrier 4 partially encloses the hinge element 3 with the guide area 4.4 along the Fig.5 Along the longitudinal direction of the hinge element 3, ie transverse to the cutting plane of the Fig.5 , the guide area 3.4 surrounds the guide area 4.4 of the axle carrier 4 and thus supports it.

In Fig.4 the axle carrier 4 is in accordance with Fig.1 shown in more detail. The distance between the axle carrier 4 and the hinge element 3 can be adjusted using the adjusting element 5 together with the distance of the hinge axis A. The dumbbell-shaped axle carrier 4 has a cylindrical joint pin 4.3 arranged coaxially to the hinge axis A for the articulated arrangement of the hinge element 2. In addition, the axle carrier 4 has two connecting elements 4.5 located opposite each other along the hinge axis A. These also serve to connect to the hinge element 2 and engage in the Fig.7 Insert the hinge element into the slots 2.5 shown.

Passages 4.2 make the connecting means for connecting the hinge element 3 accessible from the outside via the connecting recesses 3.2, without the axle support 4 having to be removed for this purpose. For this purpose, the passages 4.2 are arranged on the axle support 4 in such a way that they are aligned with the connecting recesses 3.2 when the hinge 1 is assembled.

The bearing openings 4.1 are arranged on both sides of the hinge pin 4.3, which allows the adjusting elements 5 to be arranged on both sides. In addition to adjusting the distance between the hinge axis A and the hinge element 3, the two adjusting elements 5 also allow the hinge axis A to be tilted. The adjustable inclination of the hinge axis A can compensate for any distortion of the locking element and/or the frame caused by manufacturing tolerances or usage. Different distances between the hinge axis A and the hinge element 3 are set using the adjusting elements 5, which results in an inclination of the hinge axis A relative to the hinge element 3.

As described above, the adjusting element 5 is mounted in a bearing opening 4.1 of the axle carrier 4. The bearing opening 4.1 has a bearing area 4.11 and an insertion area 4.12. In comparison to the bearing area 4.11, the insertion area 4.12 is larger. This makes it possible to insert the adjusting element 5 with the thread 5.1 and/or the head 5.3 first into the insertion area 4.12. The inner radius of the insertion area 4.12 is at least as large as the outer diameter of the thread 5.1 and/or the head 5.3 of the adjusting element 5.

The bearing area 4.11, on the other hand, has an inner diameter below the outer diameter of the thread 5.1 and/or the head 5.3 of the actuating element 5. This smaller inner diameter of the bearing area 4.11 prevents an actuating element 5 mounted in the bearing area 4.11 from escaping from the bearing area 4.11 in the axial direction. An axial restriction of the freedom of movement of the actuating element 5 is achieved. The radius of the bearing area 4.11 essentially corresponds to the outer diameter of the groove 5.2 of the actuating element 5. Likewise, the axial dimension of the bearing area 4.11 essentially corresponds to the axial length of the groove 5.2. In this way, the groove 5.2 can be positively mounted in the bearing area 4.11. The thrust and tensile forces are thus transferred from the actuating element 5 to the axle carrier 4 to adjust the distance from the hinge element 3.

The bearing area 4.11 and the insertion area 4.12 form a keyhole-shaped bearing opening 4.1, in which the two essentially circular areas 4.11 and 4.12 are connected to one another via an elongated hole running between the two areas 4.11, 4.12. The smaller diameter of this elongated hole essentially corresponds to the inner diameter of the bearing area 4.11.

To accommodate the head 5.3 of the adjusting element 5, the bearing opening 4.1 is arranged in a countersunk hole 4.6. This allows the adjusting element 5 to be mounted in the bearing opening 4.1 and prevents the head 5.3 from protruding from the top of the axle carrier 4.

The bearing opening 4.1 and the guide area 4.4 are arranged in relation to one another in such a way that when the hinge 1 is mounted, in which the guide area 4.4 rests against the guide area 3.4, the adjusting element 5 fixed via the counter thread 3.1 cannot be transferred from the bearing area 4.11 into the insertion area 4.12. An unintentional emergence of the adjusting element 5 from the bearing opening 4.1 and thus a detachment of the axle carrier 4 from the adjusting element 5 are prevented in the mounted state.

When assembling the hinge 1, the adjusting element 5 is first inserted into the insertion area 4.12 of the axle carrier 4 and moved transversely to the insertion direction to engage the groove 5.2 in the bearing area 4.11. The adjusting element 5 mounted in the axle carrier 4 is then connected to the hinge element 3 by means of the thread 5.1 and the counter thread 3.1. Alternatively, the thread 5.1 and the counter thread 3.1 are first engaged and the axle carrier 4 is then inserted onto the adjusting element 5 in such a way that the adjusting element 5 is inserted into the insertion area 4.12. The axle carrier 4 is then moved relative to the adjusting element 5 and the hinge element 3 to transfer the adjusting element 5 to the bearing area 4.11. The second alternative assumes that the axle carrier 4 can be spaced from the hinge element 3 via the adjusting element 5 in such a way that the guide areas 3.4, 4.4 no longer abut one another.

The Fig. 5 and Fig. 6 show sectional views of the hinge 1 according to Fig.1 for different set distances of the hinge axis A to the hinge element 3. In Fig.5 there is a smaller distance D1 between the hinge element 3 and the axle carrier 4. The guide areas 3.4 and 4.4 lie against each other. The projection 3.02 forms part of the guide area 4.4 and extends it along the axial direction of the actuating element 5. Transverse to the axis of the actuating element 5 acting Hinge forces can be transferred from the axle carrier 4 to the hinge element 3 without affecting the adjusting element 5.

In order to change the distance D1 and thus also to adjust the distance of the hinge axis A arranged on the axle support 4 from the hinge element 3, the adjusting element 5 is rotated about its longitudinal axis. Through the interaction of the thread 5.1 and the counter thread 3.1, this rotary movement is converted into an axial longitudinal movement of the adjusting element 5. A pushing or pulling force exerted by the axial longitudinal movement is transmitted to the axle support 4 by the axial fixation of the adjusting element 5 described above. The axle support 4 is moved away from or towards the hinge element 3 by the pushing or pulling force and is guided by the guide 3.4, 4.4.

The maximum achievable distance D2, which still allows a guided movement, is in Fig.6 shown. The contact surfaces 3.41 and 4.41 of the guide areas 3.4, 4.4 are still in contact with each other in the area of the section shown on the left, while the parts of the guide areas 3.4, 4.4 shown on the right are no longer in contact with each other.

Fig.7 shows a perspective view of the hinge element 2 on the locking element side. The slot-shaped receptacles 2.5 can be seen, in which the connecting elements 4.5 engage to connect the axle support 4 with the hinge element 2. Along the hinge axis A, between these receptacles 2.5, there is a joint eye 2.1 as part of a rod-shaped projection 2.6. This joint eye 2.1 is arranged on the joint pin 4.3 of the axle support 4 and enables the articulated connection of the two hinge elements 2, 3 by means of the axle support 4. For this purpose, the joint pin 4.3 lies on the inner surface of the joint eye 2.1, which enables an articulated guidance of the pivoting movement of the hinge element 2 relative to the axle support 4. The joint eye 2.1 is designed in the manner of a one-sided through opening that is open on the circumference through the projection 2.6. For arrangement on the hinge pin 4.3, the hinge eye 2.1 can be brought towards the hinge pin 4.3 in the direction of the area that is open on one side. Alternatively, the hinge eye 2.1 can also be designed as a through opening that is closed on the circumference, whereby a circumferential form fit of the hinge pin 4.3 with the hinge eye 2.1 can be achieved.

A joint eye 2.1 that is open on one side allows easy release and locking of the joint eye 2.1 on the joint pin 4.3. For this purpose, the hinge element 2 has a locking mechanism 2.3, which can be used, for example, in Fig.8 can be seen. This locking mechanism 2.3 is moved parallel to the projection 2.6 out of a recess 2.2 for locking and into the recess 2.2 for releasing the joint eye 2.1 from the joint pin 4.3. In the locked state, the locking mechanism 2.3 closes the joint eye 2.1, which is open on one side, in such a way that the joint eye 2.1 and the locking mechanism 2.3 rest positively on the joint pin 4.3. In the unlocked state, the locking mechanism 2.3 is moved into the recess 2.2 in such a way that it releases the joint pin 4.3 resting on the joint eye 2.1. In the unlocked state, the locking mechanism 2.3 is preferably completely retracted into the recess 2.2.

The actuating device 6, which is designed in the manner of a handle and is arranged in the recess 2.4 of the hinge element 2, serves to actuate the locking mechanism 2.3.

The hinge 1 equipped with a locking mechanism 2.3 can be used not only as a hinge but also as a locking hinge for closing and/or locking. The hinge 1 can thus be used as a replacement or supplement to a lock. If several of these hinges 1 are used at different points on the locking element of a lockable opening, they can enable the opening direction of the locking element to be selected. The hinge eye 2.1 of the hinge 1, around which the locking element is to be pivoted, can remain in a position locked with the hinge pin 4.3, while the hinge eyes 2.1 of the other hinges 1 are released from the hinge pins 4.3 assigned to them by moving the respective locking mechanisms 2.3. The locking element can then be pivoted around the still locked hinge 1. To lock the locking element in its closed position, the respective hinge pins 4.3 and hinge eyes 2.1 of the hinges 1 are locked together. In this way, a particularly stable locking of the locking element can be achieved.

In the following, a further embodiment of a hinge 1 according to the invention will be discussed. Elements with the same effect are designated with the same reference numerals as were already used in the description of the first embodiment. The main difference from the first embodiment lies in the design details of the hinge element 3 and the axle support 4. In the following, therefore, only the differences from the first embodiment will be discussed, whereby the above description also applies to the second embodiment.

Fig.8 shows the hinge 1 with the two hinge elements 2, 3, the axle support 4 and the actuating device 6. The actuating device 6 and the hinge element 2 differ from the first embodiment only in terms of their contour shape, their technical function is not affected by this. The axle support 4 is more angular and less curved compared to the first embodiment, which means that a smaller width transverse to the hinge axis is achieved in a space-saving manner. A is achieved. The hinge element 3 is in Fig.8 shown separated from the axle support 4. This is for the sake of clarity, since the axle support 4 covers the hinge element 3 when the hinge 1 is assembled.

Fig.9 shows a sectional view of the hinge at a minimum set distance of the hinge axis A from the hinge element 3. The adjusting movement of the axle carrier 4 is guided by the two adjacent guide areas 3.4, 4.4 on both sides both in and across the cutting direction. The guide area 4.4 of the axle carrier 4 surrounds the guide area 3.4 of the hinge element 3 on both sides. The inward-facing contact surface 4.41 of the axle carrier 4 rests against the outward-facing contact surface 3.41 of the hinge element 3 to guide the adjusting movement.

As in Fig.10 As can be seen, the guide areas 3.4 and 4.4 extend not only along the long sides of the axle support 4 or the hinge element 3, but also along the respective short sides. In a structurally simple manner, the inner circumferential surface of the axle support 4 and the outer circumferential surface of the hinge element 3 form the contact surfaces 3.41, 4.41 that abut one another to guide the actuating movement. The axle support 4 and the hinge element 3 are formed complementarily to one another in the manner of a plug connection, in which the axle support 4 surrounds the beam-shaped hinge element 3 on the circumference.

To support the adjusting elements 5, the axle carrier 4 has keyhole-shaped bearing openings 4.1, which are arranged in countersunk holes 4.6. The two bearing openings 4.1 are aligned with each other in such a way that the bearing areas 4.11 of the two bearing openings 4.1 face each other. This provides additional protection for the adjusting elements 5 against coming out of the bearing openings 4.1.

Since the grooves 5.2 prevent the adjusting elements 5 from protruding in the axial direction from the bearing areas 4.11, the adjusting elements 5 would have to be transferred to the larger insertion areas 4.12 in order to be able to emerge from these. However, due to the arrangement of the bearing areas 4.11 in alignment with the mating threads 3.1, an adjusting element 5 connected to the mating thread 3.1 cannot be freely transferred into the insertion area 4.12. The mutually facing bearing areas 4.11 of the bearing openings 4.1 also prevent the axle carrier 4 from being displaced relative to the adjusting elements 5 fixed relative to the hinge element 3 in such a way that the adjusting elements 5 enter the insertion areas 4.12. This would require the axle carrier 4 to be moved in a different direction along the hinge axis A for each of the two adjusting elements 5. Such a movement, which corresponds to a compression of the axle carrier 4, is not possible with the fixed axle carrier 4. Therefore, the adjusting elements 5 cannot emerge from the bearing opening 4.1 without being released from the hinge element 3.

By using the hinge 1 described above and the method for adjusting the hinge 1, a simpler and more precise alignment can be achieved.
