Description

The invention relates to a hinge for the pivotable connection of a door to a frame, having a first hinge element for arrangement on the door and a second hinge element for arrangement on the frame, one of the two hinge elements being a hinge eye and the other hinge element being a hinge axis arranged in a rotationally fixed manner on an axle holder has, which can be coupled to each other for the pivotable arrangement of the door on the frame, and with a securing element for securing the two hinge elements against decoupling. Furthermore, the invention relates to a device with a frame and a door which is pivotably connected to the frame via a hinge.

Corresponding hinges are used in very different areas of technology and are used to arrange doors pivotably on a fixed frame, the frame being part of a cabinet, for example. Doors are to be understood not only as doors in the actual sense, but also flaps, hatches, windows and other pivoting closing elements.

The hinges essentially consist of two pivotally coupled hinge elements, of which one is arranged on the frame and the other on the door. The two hinge elements are then pivotally connected to one another, so that the door can be pivoted relative to the frame and thus opened and closed.

In terms of construction, it is known if one of the two hinge elements has a hinge axis and the other hinge element has a hinge eye. Because of the arrangement of the hinge eye on the hinge axis, a pivotable connection of the two hinge elements can be realized in a comparatively simple manner. In addition, there are also hinges in which both hinge elements have hinge eyes and in which the hinge axis is designed as a separate component that can be pushed through the two hinge eyes. However, the assembly of these hinges is more complex due to the separate hinge axis.

In practice, the hinge element arranged on the door usually has the hinge eye and the hinge element arranged on the frame has the hinge axis. The hinge axis is usually held in a position extending essentially parallel to the frame by means of an axis holder and is thus firmly connected to the frame by means of the axis holder. When installing the door or connecting the door to the frame, which is also generally referred to as "hanging the door", the door is first positioned in such a way that the hinge eye is as concentric as possible above the hinge axis. When the door is then lowered, the hinge eye slides axially along the hinge axle until it rests on the axle holder. The hinge eye is then pivotally connected to the hinge axis and thus also allows a pivoting movement of the door relative to the frame.

If the hinge eye is arranged on the frame and the hinge axis on the door, the assembly or hanging process works accordingly.

Although the hinged door can be pivoted reliably and, due to its weight, there is generally no risk of the hinge eye jumping off the hinge pin, there is a certain risk of this during transport. Because if the door is arranged on a cupboard, for example, it can happen that the door is unintentionally detached when the cupboard is being transported.

Furthermore, problems can also arise if the corresponding cabinet is still empty or not anchored to the floor or a wall. Because when the door is opened, the shift in focus that goes with it can cause the cabinet to tip forward, hitting the door on the floor and then lifting it off its hinges.

For this reason it is known to provide a securing element which secures the two hinge elements against decoupling and ensures that the hinge eye cannot move in the axial direction relative to the hinge axis. In the simplest case, a locking ring or a locking splint can be provided for this purpose, for example, which are connected to the hinge axis above the hinge eye.

Although these securing elements generally ensure reliable securing of the two hinge elements, assembly is somewhat tricky in some cases, since there is usually only little space available for assembling the securing elements above the hinge eye. Furthermore, the assembly or disassembly of the security elements often cannot be accomplished without the use of tools.

the DE 20 2013 005 884 U1 discloses a hinge with a first main part, which is connected to a first sleeve to form a whole part and the inner wall of which is equipped with a sliding recess, a second main part, which is connected to a second sleeve to form a whole part, a bushing, which extends through the first shell and the second shell and is provided on its surface with a through hole, a pivot pin which can be passed through the bush and is provided with a groove on its surface, and a ball, wherein when the ball is in the first slide hollow and the through hole, the first body and the second body are connected into one whole, and when the ball is in the first slide hollow in the through hole and the groove, the trunnion and the bush of the first shell and the second Let the case separate, thereby allowing the separation of the first main part from the second main part.

The object of the invention is to provide a hinge and a device with a frame and a door which is pivotably connected to the frame via a hinge, the hinge elements of the hinge being able to be secured against decoupling in the most user-friendly manner possible.

This object is achieved with a hinge of the type mentioned at the outset in that the securing element and the hinge eye are arranged on opposite sides of the axle holder.

Since the securing element and the hinge eye are arranged on opposite sides of the axle holder, significantly more space is available for assembly and disassembly of the securing element, which insofar enables the two hinge elements to be secured in a user-friendly manner.

It has turned out to be advantageous if the securing element can be rotated in relation to the second hinge element. Due to the rotatability, the securing element is not limited to being mounted in a predetermined position, as is the case with a cotter pin, for example. Rather, the securing element can also be mounted blind due to its ability to rotate and is not restricted to a specific position for mounting. From a structural point of view, the securing element can be designed in the form of a block, which ensures good handling and in this respect also facilitates assembly.

With regard to the arrangement of the securing element, it has proven to be advantageous if this is connected to the second hinge element and, in particular, is arranged on a securing axis of the second hinge element. In this respect, the securing element can be connected to the second hinge element via the hinge axis. The securing axis can be in alignment with the hinge axis and thus the securing axis and the hinge axis can form a common axis of rotation for the hinge. The securing element can be designed in the manner of a securing hinge eye and in this respect can basically be arranged analogously to the hinge eye.

In order to mount the securing element, it is proposed that this can be slipped onto the securing axis. Such a plugging allows a very simple assembly, which can also be carried out blind. The securing element can have a bore that enables a corresponding plug-in connection. The securing axis can be designed in the form of a bolt or pin, just like the hinge axis. The securing element can be moved towards the axle holder in the axial direction when it is plugged on.

In a development of the invention, it has proven to be advantageous if the securing element can be latched to the second hinge element, in particular to the securing axis. A corresponding latching connection is characterized in particular by the fact that it enables tool-free assembly. This is because the securing element only has to be plugged onto the securing axis for connection and can then no longer be moved axially relative to the securing axis after a latching position has been reached. Advantageously, a rotary movement of the securing element on the securing axis is not impaired by the latching, so that the securing element can be rotated freely about the securing axis even in the latched position. In order to release the securing element from the securing pin again, it can be pulled down from the securing pin with a predefined force. The force required for loosening can be dimensioned in such a way that it is not reached during normal operation and also during transport, so that the securing element is reliably connected to the securing axis. If sufficient force is applied, the snap-in connection releases automatically and the securing element can be dismantled without the use of tools.

In terms of construction, it has proven to be advantageous if the securing element can be latched to the securing pin via a latching claw. A reliable connection between the securing element and the securing axis can be ensured via the latching claw. The rest The claw can deform elastically when the safety element is attached and then automatically snap behind it when it reaches a corresponding locking groove. In practice, it has proven to be advantageous if the latching claw is designed in the shape of a segment of a circle. Such a design allows the latching claw to partially surround the securing pin and to rest on the circumference of the securing pin. A segment angle of approximately 90 degrees has proven to be particularly advantageous, since this not only enables reliable latching, but also allows the latching to be released again in a comparatively simple manner.

With regard to the securing pin, it has proven to be advantageous if it has a latching groove into which the securing element can latch. Through the locking groove, the securing element or the locking claw can engage in the locking groove in any position. The latching groove also allows the securing element to be rotated 360 degrees around the securing axis in the latched position.

With regard to the latching, it has also proven to be advantageous if the latching of the securing element can be released manually from the securing axis. In this respect, no additional tool is then required not only for assembly but also for disassembly of the securing element. For disassembly, for example, a finger can be gripped behind the latching claw and this can be pivoted out of the latching groove in the radial direction.

In a further development of the invention, it is proposed that the securing element bear against the axle holder. The axle holder can thus be arranged between the securing element and the hinge eye. Just like the hinge eye, the securing element can also slide off the axle holder during a pivoting movement of the door.

With regard to the loading of the securing element, it has proven to be advantageous if this is arranged outside of the flow of forces between the hinge elements. The door can be supported by the two hinge elements relative to the frame, so that in particular the weight of the door is conducted through the two hinge elements into the frame and thus past the securing element. The security element is thus not exposed to any great stress and can be used for doors with very different dimensions and with different weights. The weight of the door can primarily be absorbed by the hinge axis or the axis support.

With regard to the second hinge element, it has proven to be advantageous if the securing axis and the hinge axis are connected to one another in one piece. It is also advantageous if the securing axis and the hinge axis are designed as bolts passing through the axis holder. The bolt can be straight and pointed or chamfered at its ends, which simplifies the connection or assembly of both the securing element and the hinge eye. Since the bolt sometimes has to absorb large forces, it is made of metal in particular. The axle holder can be designed as a separate element, which holds the bolt, for example, in a frictional or positive manner. Alternatively, the axle holder can also be connected in one piece to the bolt or alternatively only to the hinge axle or the safety axle.

It has also turned out to be advantageous if the hinge axis and the safety axis protrude in relation to the axis holder. The hinge eye or the securing element can be arranged on the respective protruding parts. The hinge axis may extend upward relative to the axis holder and the securing axis may extend downward relative to the axis holder. Alternatively, however, it is also possible for the securing axis to extend upwards and the hinge axis to extend downwards. This can depend on whether the hinge eye is arranged on the door side or on the frame side. If the hinge eye is arranged on the door side, it can rest on the axle holder, for example. If the hinge eye is arranged on the frame side and the hinge axis on the door side, the axis holder can rest on the hinge eye. However, the hinge can be used to connect a door to a frame not only on its vertical side but also on its horizontal side. In this respect, the hinge eye would be either on the right or left of the axle holder.

Furthermore, it has turned out to be advantageous with regard to the second hinge element if this is embodied symmetrically. Due to the symmetrical design, the same hinge element can be used both for doors hinged on the right and for doors hinged on the left. The safety axis of a door hinged on the right then becomes the hinge axis on a door hinged on the left and vice versa. The axis of symmetry can extend centrally through the axle holder and transversely to the hinge axis or to the axis of rotation.

According to an advantageous development of the invention, it is proposed that the hinge eye and the hinge axis can be hooked into one another. This configuration allows the door is arranged pivotably on the frame directly after the coupling of the two hinge elements. The securing element can be installed in a later step if the door is already connected to the frame or is hanging on the frame. In this respect, the door does not have to be held firmly when installing the securing element or when securing the two hinge elements. Being able to be hooked in does not necessarily mean that the weight of the door has to be supported by the frame. Rather, it means that the door is pivotally connected to the frame. For example, the flap of a chest is also attached to the frame, even though the hinge elements do not bear the weight of the door.

Furthermore, it is proposed that the hinge eye rests against the axle holder and slides off it when the door moves. The door can thus be supported on the axle holder when the hinge eye is arranged on the door side and the axle holder can be supported on the hinge eye when the hinge eye is arranged on the frame side. To protect the material, a washer can also be provided, which in particular can have good sliding properties.

Furthermore, it has proven to be advantageous if the hinge axis is arranged inside the hinge eye. In contrast to the safety splints or safety pins described above, the safety element does not require any space on the side of the axle support on which the hinge eye is arranged, so that the hinge axle does not have to protrude in relation to the hinge eye. Rather, the hinge axis can be just as long or shorter than the hinge eye. Since the hinge axis is advantageously just as long as the safety axis, the same applies to the safety axis.

In order to ensure reliable securing, it is provided that the securing element secures the hinge eye axially on the hinge axis. The hinge eye is therefore not movable relative to the hinge axis in the axial direction and also cannot jump off the hinge axis.

According to an advantageous development, it is proposed that the securing element is connected to the first hinge element, in particular rotationally coupled. This rotary coupling enables the securing element to rotate about the securing axis together with the door or with the hinge eye when the door pivots. Nevertheless, an axial movement of the securing element relative to the first hinge element or the door can be prevented. In this respect, the hinge elements can be reliably coupled and secured to one another in any pivoting position of the door. In addition to connecting the two hinge elements via the hinge axis and the hinge eye, the securing element can thus provide a second connection point between the two hinge elements.

In terms of construction, it has proven to be advantageous if the securing element has a latching device via which it can be latched to the first hinge element or to the door. The locking device allows the securing element to be connected to the first hinge element or to the door without the use of tools. For this purpose, the securing element can be plugged onto the securing axis and then rotated around the securing axis until the securing element comes into contact with the first hinge element or with the door and can then latch accordingly with the hinge element or with the door. In the latched position, the securing element can no longer be rotated with respect to the first hinge element or the door, but rather the securing element is then rotationally coupled to the first hinge element or the door. For connection to the door, the latter can have mounting bolts on the inside, with which the safety element can latch. The mounting bolts can, for example, be welded or riveted to the inside of the door. In the opposite arrangement, ie when the first hinge element is arranged on the frame side and the second hinge element is arranged on the door side, the securing element can correspondingly engage with the first hinge element or with the frame.

In an alternative embodiment, the securing element can also be magnetically coupled in rotation with the first hinge element or with the door.

Furthermore, with regard to the latching device, it has proven to be advantageous if it has two latching arms which can engage in a latching contour of the first hinge element. The latching arms can automatically latch with the latching contour when the latched position is reached, thereby ensuring a reliable connection between the first hinge element and the securing element. The latching arms can be deformed in the elastic region when the securing element is pivoted if they come into contact with the latching contour and automatically reach behind the latching contour when the latched position is reached. If the fuse element is to be latched to the door or to the frame, it can be arranged on the door or on the frame designated mounting bolts also have a corresponding latching contour that enables latching with the latching device of the securing element. Other latching contours or a different arrangement on the frame and/or door are also possible.

With regard to the design of the securing element, it has also proven to be advantageous if it has a recess for receiving a mounting bolt. The latching device can be arranged in or on the recess if the securing element is to latch with the door or with the mounting element. Even if the securing element is intended to snap into place with the first hinge element, the cutout means that the door can nevertheless have corresponding assembly bolts which, however, are then not used, at least for locking into place with the securing element. In this respect, the recess can be designed as a receiving bore. The door can have more assembly bolts than are actually required, which means that the same door can be used in different installation situations and therefore different assembly bolts can be used for a door hinged on the left than for a door hinged on the right.

Furthermore, it has proven to be advantageous if the securing element is arranged and designed in such a way that it automatically latches with the first hinge element or with the door or with the frame when the door is closed. This configuration simplifies assembly even further. Because the security element simply has to be plugged onto the security axis and this then automatically engages with the first hinge element or with the door or with the frame when the door is closed. In this respect, an auto-lock function is created, and even if the hinge element is not correctly latched to the door or to the first hinge element or the frame, there is no risk of the two hinge elements unintentionally decoupling from one another again. The safety element is automatically engaged the first time the door is closed. Even if several security elements are provided, this is advantageous with regard to assembly, since all the security elements latch at once when the door is closed. This also simplifies the assembly of larger doors.

With regard to the first hinge element, it has proven to be advantageous if this has a latching contour into which the latching device of the securing element can latch. The latching contour can ensure a reliable connection of the securing element to the first hinge element when this is latched into the latching device. It is also advantageous if the first hinge element has two latching contours for different installation situations. One latching contour can be used, for example, when the door is hinged to the left, and the other latching contour can be used when the door is hinged to the right. In this respect, it can be provided that only one of the latching contours is ever used for latching with the securing element.

Furthermore, with regard to dismantling, it is proposed that the locking device be manually detachable from the locking contour. This configuration makes it possible to the extent that no tools are required for disassembly either. Rather, the securing element can be rotated by hand about the securing axis, so that the latching of the securing element with the first hinge element or the door is released. If the connection is separated accordingly, the two hinge elements can also be moved relative to one another in the axial direction and the door can be unhooked from the frame accordingly. The force required to release the latching is dimensioned in such a way that it can be applied by hand, but is not reached during normal operation and also during transport. To release the locking device, it can also be provided, for example, that the two locking arms are deformed by hand, for example pressed together, in order to release the connection.
With regard to the first hinge element, it has proven to be advantageous if this has a mounting element with two mounting points for the optional arrangement of the hinge eye. The hinge eye can thus be connected to one of the two mounting points. For example, a different mounting point can be used when the door is hinged on the right than when the door is hinged on the left. The mounting element can have holes that are adapted to the position of the mounting bolts of the door. In this respect, the mounting element can be plugged over the mounting bolts of the door. The hinge eye can be connected to one of the two mounting bolts so that the hinge eye then also connects the mounting element to the door. The mounting bolts are then used to connect the hinge eye to the mounting element at the respective mounting point. For example, a screw connection can be provided for the connection. The corresponding mounting points can be arranged in the area of the latching contours, so that depending on the door stop one latching contour is available for latching with the securing element and the other latching contour is blocked by the hinge eye.

Furthermore, it has proven to be advantageous if the mounting element is arranged between the hinge eye and the door. That The hinge eye can be connected to the mounting bolt of the door via a screw connection, so that the mounting element is then connected to the door at the same time via the corresponding screw connection. The mounting element can have a flat shape at least in the area of the mounting points. Furthermore, the mounting element can extend parallel to the hinge axis.

Furthermore, it has proven to be advantageous if the mounting element is configured symmetrically. In this respect, the mounting element can be used both for doors hinged on the right and for doors hinged on the left. Analogously to the symmetry of the second hinge element, the axis of symmetry can extend transversely to the hinge axis or to the axis of rotation of the hinge.

In terms of construction, it has proven to be advantageous if the first hinge element has a recess in which the axle carrier can be accommodated when the door is closed. When the door is closed, the axle carrier can therefore reach very close to the inside of the door and thus also make direct contact with it. This is also associated with a larger opening angle of the door, since the end of the door can hit the inside of the stop support facing the door frame when the door is opened to the maximum extent. The recess can have a rectangular shape and can be part of the mounting element of the first hinge element.

In a development of the invention, it is proposed that the first hinge element has at least one swing-out ramp which, when the two hinge elements are coupled, can rotate the securing element into a position that does not impede the coupling process. The swing-out ramp simplifies the assembly of the door. Because if the securing element is already connected to the securing axis before the two hinge elements are coupled to one another and the door is hung accordingly in the frame, this could possibly get in the way and impede or complicate coupling of the hinge elements. The swing-out ramp can thus be designed and set up in such a way that the securing element is automatically rotated away about the securing axis when the two hinge elements are coupled, ie when there is an axial relative movement of the two hinge elements. In this respect, a collision between the securing element and, for example, the mounting bolt can be prevented. In this respect, it is also possible to mount the security elements on the security axis before the actual assembly of the door, as a result of which the assembly process can be accelerated overall. The swing-out ramp is advantageously part of the mounting element.

Furthermore, it has proven to be advantageous if the first hinge element has two swing-out ramps that lie opposite one another. The securing element can thus be reliably swung out independently of the stop of the door when the two hinge elements are coupled to one another. If the first hinge element is used for a door hinged on the left or for a door hinged on the right, different swing-out ramps can be used in this respect. The recess can be arranged between the two swing-out ramps.

In terms of construction, it is proposed with regard to the swing-out ramp that it has a ramp flank and in particular a horizontal flank. The ramp flank can enclose an acute angle with the inner surface of the door, which enables the securing element to be pivoted out reliably when the two hinge elements are coupled. The horizontal flank can be arranged perpendicularly to the inner surface of the door and perpendicularly to the hinge axis or to the axis of rotation of the hinge. The horizontal edge can thus serve as a contact surface for the securing element or the hinge eye. If two swing-out ramps are provided, the securing element can be arranged or rest on one of the two horizontal flanks and the hinge eye on the other horizontal flank.

Furthermore, it has proven to be advantageous if the ramp flanks of the two swing-out ramps face away from one another. The ramp flanks thus point outwards, so that it is ensured that the securing element comes into contact with the securing element when the hinge elements are coupled.
The above descriptions apply both to a first hinge element arranged on a door and a second hinge element arranged on the frame and in the same way, possibly with appropriate adjustments, also for a first hinge element arranged on the frame and for a second hinge element arranged on the door.

In order to solve the above-mentioned problem, it is provided in a device with a frame and a door that is pivotably connected to the frame via a hinge that the hinge is designed in the manner described above. The advantages already described with regard to the hinge result.

With regard to this device, it has proven to be advantageous if the door can be pivoted to the frame via a plurality of hinges connected is. Multiple hinges allow the door to bear against the frame at multiple points, reducing the stress on each hinge. The axes of rotation of the individual hinges can be aligned, so that a reliable pivoting movement of the door is ensured. When hanging the door, the hinge elements of all hinges can be coupled together at the same time. In this respect, the swing-out ramp also has advantages, in particular when a plurality of hinges are provided, since it is not necessary to ensure before assembly that all the securing elements are in a corresponding position. The same applies to the auto-lock function. Because it is sufficient to close the hinged door only once, in order thereby to couple or latch all security elements with the door or with the first hinge element.

Furthermore, it has proven to be advantageous with regard to the door if it is optionally attached to the right or left of the frame, with the door having several, in particular two, mounting bolts for each hinge and with different mounting bolts being used for a right-hand and a left-hand door. The first hinge element or the mounting element can thus also have bores for all mounting bolts, so that the same hinge element can also be used for doors hinged on the right and for doors hinged on the left, as has already been described above.

In the representation of 1a and 1b 1 shows a piece of frame 30 which may, for example, be part of a cabinet made of several metal sheets. A hinge element 2 is fastened to the frame 30 and consists essentially of three elements, namely an axle carrier 2.1 and a hinge axis 2.2 and a securing axis 2.3. The hinge axis 2.2 and the securing axis 2.3 are connected to one another in one piece and in this respect are designed as a continuous bolt which is non-rotatably fixed in the axis holder 2.1 and which is arranged at a distance from the frame 30 via the axis holder 2.1.

The frame 30 or the cabinet has an opening, not shown in detail in the figures, which can be closed via a door 20 . A section of the door 20 is in the 1b shown. On the inside of the door 20, this is also connected to a hinge element 1, which can be pivotally coupled to the second hinge element 2 on the frame. The first hinge element 1 has a hinge eye 1.1, which is connected to the door 20 via a screw connection. About the two hinge elements 1, 2, the door 20 can be pivotally connected to the frame 30, so that the door 20 in the 2 B pivoted axis of rotation D shown and extending centrally through the hinge axis 2.2 and can thus be opened and closed.

In the 2a the corresponding coupled or connected position is shown. For this purpose, the door 20 was positioned in such a way that the hinge eye 1.1 is arranged concentrically above the hinge axis 2.2. By lowering the door 20, the hinge eye 1.2 then moves in the axial direction along the hinge axis 2.2 until it has reached the axis holder 2.1. When the first hinge element 1 or the hinge eye 1.1 then rests on the axle holder 2.1 of the second hinge element 2, the door 20 is in the end position and this is then coupled to the frame 30 so that it can pivot. During this coupling process, the hinge eye 1.1 is placed onto the hinge axis 2.2 from above, with the door 20 also being said to be hung in the frame 30.

In the corresponding position, the door 20 can be pivoted in relation to the frame 30 and can therefore already be opened and closed, but the door 20 is not yet secured to the frame. Because this can also go up again in the reverse order be lifted off the frame 30. It is true that with heavy and upright doors 20 this is not usually a major problem. However, especially during transport, for example when the cabinet is in an inclined position, it can easily happen that the hinge eye 1.1 slips off the hinge axis 2.2 again. In order to prevent such an unintentional decoupling of the two hinge elements 1, 2, a securing element 3 is provided, as shown in FIG 2 B can be seen.

The fuse element 3 can be plugged onto the fuse axis 2.3 from below in the axial direction until it is in the 2c has reached the position shown. An advantage of the securing element 3 is that no tool is required for assembly and that the connection to the securing axis 2.3 is designed so simply that assembly can even be carried out blindly. Like this in the 2a can be seen, the securing axis 2.3 has a latching groove 2.4, which is designed as a circumferential recess. This latching groove 2.4 serves to latch the securing element 3 with the securing axis 2.3, so that this is in the attached position according to FIG 2c can no longer be easily deducted from the securing axis 2.3.

In order to enable a corresponding latching connection with the securing axis 2.3, the securing element 3 has a latching claw 3.3, which can be seen in the enlarged perspective detailed views of FIG 5a and 5b can be seen. When attaching the securing element 3 to the securing axis 2.3, the latching claw 3.3 is first swung out a little and thereby deformed in the elastic range. Like this, for example, in the 1a As can be seen, the securing pin 2.3 has a pointed tip at its lower end, which simplifies the attachment of the securing element 3 and therefore also the elastic deformation of the latching claw 3.3. If the securing element 3 is fitted so far onto the securing axis 2.3 that the locking claw 3.3 has reached the locking groove 2.4, the locking claw 3.3 automatically engages in the locking groove 2.4 and thus secures the securing element 3 on the locking axis 2.3.

Even in this latched and axially immobile position, however, the securing element 3 is still freely rotatable relative to the securing axis 2.3. When the securing element 3 is plugged onto the securing axis 2.3, the two hinge elements 1, 2 are initially not secured against decoupling. This is because the securing element 3 must first be coupled to the first hinge element 1 .

In order to connect the securing element 3 to the first hinge element 1 accordingly, the securing element 3 must be in the 2d The position shown can be pivoted about the securing axis 2.3. The connection of the securing element 3 to the first hinge element 1 is also effected via a snap-in connection, so that no tool is required for this connection either, rather the securing element 3 can be connected to the first hinge element 1 very easily by hand.

The latching of the securing element 3 with the first hinge element 1 is shown in the enlarged view of FIG 6a and 6b to recognize. The securing element 3 has a latching device 3.1, which includes two latching arms 3.11. If the fuse element 3 from the in the 6a shown position in the 6b shown latching position is pressed, the two latching arms 3.11 are elastically deformed and then engage in the latching contour 1.5 of the first hinge element 1 after the latched position has been reached. If the securing element 3 is latched accordingly, it can be rotated about the axis of rotation D together with the first hinge element 1 or with the door 20 . In this respect, the securing element 3 is then rotationally coupled to the first hinge element 1 . The securing element 3 thus establishes a connection between the first and the second hinge element 1, 2 and ensures that the first hinge element 1 can rotate relative to the second hinge element 2, but it prevents a translatory movement of the two hinge elements 1, 2. The first hinge element 1 or the hinge eye 1.1 is then secured axially on the hinge axis 2.2 via the securing element 3 and the door 20 is thus reliably connected to the frame 30.

Furthermore, it is not absolutely necessary for the securing element 3 to be turned by hand and latched to the hinge element 1, but when the door 20 is closed, the securing element 3 latches automatically to the first hinge element 1. This auto-lock function is based on the 4a until 4c apparent. In the representation of 4a the door 20 was hung in the frame 20, and the hinge eye 1.1 rests correspondingly on top of the axle holder 2.1. Although the securing element 3 is already connected to the securing axis 2.3, it is not yet connected to the first hinge element 1. In order to close the door 20, it is pivoted about the axis of rotation D. In the position according to 4b the door 20 is still in a half-open position. However, the securing element 3 is already in contact with the frame 30 . If the door 20 is then pivoted further about the axis of rotation D, there is a relative movement of the securing element 3 against above the door 20 or opposite the first hinge element 1. The first hinge element 1 then moves towards the stationary securing element 3. When the door 20 has reached the closed position, the securing element 3 has latched into the first hinge element 1 and is thus then connected to it.

When the door 20 is opened again, the securing element 3 rotates together with the first hinge element 1 about the axis of rotation D. Especially when the door 20 is connected to the frame 30 via several hinges 10, this auto-lock function leads to a significant Ease of assembly, since by closing the door 20 all the securing elements 3 can be latched to the respective first hinge elements 1 at the same time.

In order to dismantle the door 20, the latching connection between the securing element 3 and the first hinge element 1 must first be released. This can also be done by hand without the use of tools. Because when the securing element 3 is rotated in the opposite direction about the axis of rotation D, the latching device 3.1 and the latching contour 1.5 disengage. For this purpose, the locking arms 3.11 can, for example, be pressed together somewhat, which reduces the force required to release the locking connection. When the latching is released and the securing element 3 is no longer connected to the first hinge element 1, the hinge eye 1.1 can be moved again in the axial direction relative to the second hinge element 2 and the door 20 can be removed from the frame 30 accordingly. It is not necessary to additionally detach the securing element 3 from the securing axis 2.3.

If the door 20 is to be hung again in the frame 30, the securing element 3 could possibly impede the hanging process, since this is to be described in more detail below and, for example, in FIG 2a to be recognized mounting bolt 21 could strike. The securing element 3 must therefore first be pivoted about the securing axis 2.3 into a position in which it does not impede an axial movement of the two hinge elements 1, 2. In order to automate this, the first hinge element 1 has a swing-out ramp 1.4.

If the fuse element 3, for example, in the position according to the 3a and the hinge eye 1.1 of the first hinge element 1 is placed on the axle holder 2.1 so that the hinge axis 2.2 is arranged inside the hinge eye 1.1, the swing-out ramp 1.4 comes into contact with the securing element 3 during this axial movement and pushes it to the side. The securing element 3 is thus rotated by the swing-out ramp 1.4 about the securing axis 2.3 into a position in which it does not impede an axial movement of the hinge elements 1, 2.

The geometry of swing-out ramp 1.4 essentially corresponds to that of a prism, and it has a ramp flank 1.41 and a horizontal flank 1.42. The ramp flank 1.41 encloses an acute angle with the door 20 or with the inner surface of the door 20. This acute angle, together with the rotatability of the securing element 3 on the securing axis 2.3, means that the securing element 3 is then pivoted out accordingly when the door 20 is hung. The horizontal edge 1.42 extends essentially perpendicularly to the door 20 and serves as a contact surface for the securing element 3 or for the hinge eye 1.1, as is the case, for example, in the representation of FIG 2d can be seen.

As shown in the 3b the hinge element 1 has two swing-out ramps 1.4. The reason for this is that the same hinge element 1 can be used both for doors 20 hinged on the right and for doors 20 hinged on the left. In the figures, a door 20 hinged on the right is shown, for example. If the door 20 were hinged on the left, the first hinge element 1 would have to be rotated through 180 degrees and then mounted on the left edge of the door 20 accordingly. The upper swing-out ramp 1.4 would then become the lower swing-out ramp 1.4, and this swing-out ramp 1.4 would then correspondingly push the securing element 3 to the side when it is hooked in.

How this continues for example in the 2d can be seen, the first hinge element 1 has a recess 1.3, which is arranged between the two swing-out ramps 1.4. This recess 1.3 serves to accommodate the axle holder 2.1 when the door 20 is closed, as is also the case, for example, based on a comparison of FIG 4a and 4c is evident. Through the recess 1.3, the axle holder 2.1 can rest directly on the inside of the door 20 when the door 20 is closed.

The first hinge element 1 basically consists of two elements, namely the hinge eye 1.1 and a mounting element 1.6. The swing-out ramps 1.4, the recess 1.3 and the two locking contours 1.5 are part of the mounting element 1.6. In order to connect the first hinge element 1 to the door 20, the door 20 has two mounting bolts 21 arranged on the inside of the door, each with a thread are provided. The mounting element 1.6 has bores that are adapted to the mounting bolts 21, so that the mounting element 1.6 can be slipped onto the two mounting bolts 21 and then basically rests flat against the door 20 at first. In a next step, the hinge eye 1.1 is mounted. The two mounting bolts 21 thus form two mounting points 1.2 for the hinge eye 1.1, so that this can be connected to the mounting element 1.6 at two different points. This in turn is accompanied by the door 20 striking. Because with a door 20 hinged on the right and a door 20 hinged on the left, the hinge eye 1.1 is mounted accordingly at different mounting points 1.2 of the mounting element 1.6.

The hinge eye 1.1 also has a hole and can thus be placed over the mounting bolt 21. In this position, the hinge eye 1.1 rests on the mounting element 1.6 and on one of the two horizontal flanks 1.42 of the swing-out ramps 1.4. The hinge eye 1.1 can then be firmly connected to the door 20 together with the mounting element 1.6 via a mounting bolt 21 via a nut. So that the securing element 3 can latch with the first hinge element 1 at the assembly point 1.2 not occupied by the hinge eye 1.1 despite the assembly bolts 21, the securing element 3 has a recess 3.2 into which the assembly bolt 21 not used for connection to the door can dip. This recess 3.2 is for example in the 5a to recognize. In this respect, the securing element 3 can be connected to one of the two latching contours 1.5 independently of the mounting bolt 21.

The two latching contours 1.5 of the first hinge element 1 or of the mounting element 1.6 are arranged in the area of the mounting points 1.2, so that the mounting points 1.2 enable either a screw connection with the hinge eye 1.1 or a latching connection with the securing element 3, depending on whether the hinge element 1 is intended for a door 20 hinged on the right or on the left is used.

Like the first hinge element 1, the second hinge element 2 is designed symmetrically so that it can be used both for doors 20 hinged on the left and for doors 20 hinged on the right. Since the hinge axis 2.2 and the securing axis 2.3 are of identical design and both axes 2.2, 2.3 are suitable for latching with the securing element 3 by means of corresponding locking grooves 2.4, the same axis 2.2, 2.3 can be used either as a hinge axis 2.2 or as a securing axis, depending on the installation situation 2.3 are used. Furthermore, this configuration also makes it possible, in an alternative configuration that is not shown, for the hinge axis 2.2 and the securing axis 2.3 to be arranged on the door 20 and the hinge eye 1.1 on the frame 30.

Another alternative embodiment is in the 7a , 7b shown. The difference from the embodiment described above is that the securing element 3 is not locked to the first hinge element 1, but directly to the mounting bolt 21 of the door 20 via the locking device 3.1. In this respect, the first hinge element 1 or the mounting element 1.6 does not have to have a latching contour 1.5 in this configuration, but rather the mounting bolts 21 must have a corresponding latching contour 1.5. Basically, the securing element 3 is also connected to the first hinge element 1 in this variant, but not directly, but indirectly via the door 20. As a result, however, the securing element 3 can also be rotated about the axis of rotation D together with the door 20 in this embodiment, and the securing element 3 secures the two hinge elements 1, 2 against axial movement. Since the design and functioning of the hinge 10 is otherwise identical to the hinge described above, reference is made to the above description.
