Description

Hinge with safety element

The invention relates to a hinge for the pivotable connection of a door to a frame with 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 non-rotatably attached to an axle holder has arranged hinge axis, which can be coupled to each other for pivoting arrangement of the door on the frame, and with a securing element for securing the two hinge elements against decoupling. Corresponding hinges are used in very different areas of technology and are used to pivot doors to be arranged on a festste existing frame, the frame being, for example, part of a closet can be. Doors are not only to be understood as meaning doors in the strict sense, but also flaps, hatches, windows and other pivotable 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 lowered, the hinge eye slides off axially on 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 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 retaining ring or a cotter pin 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.

Proceeding from this, the object of the invention is to provide a hinge whose hinge elements can be secured against decoupling in the most user-friendly manner possible.

With a hinge of the type mentioned at the outset, this object is achieved by the securing element and the hinge eye being arranged on opposite sides of the axle holder.

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

It has proven to be advantageous if the securing element is rotatable relative 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, for example, with a securing splint. 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 been found to be advantageous if it is connected to the second hinge element and, in particular, 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 safety axis can be in alignment with the hinge axis and thus the safety 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 in the axial direction towards the axle holder when it is plugged on.

In a further 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 snap-in connection is characterized in particular by the fact that it enables tool-free assembly. For the connection, the securing element only has to be plugged onto the securing axis and, after reaching a latching position, can no longer be moved axially with respect to the securing axis. Advantageously, a rotary movement of the securing element on the securing axis is not affected by the latching, so that the securing element can be rotated freely about the securing axis even in the latched position. To remove the fuse element from the fuse To loosen the axis, it can be pulled down from the safety axis 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 latching claw can deform elastically when the securing element is pushed on and then automatically latch behind when it reaches a corresponding latching 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 engage around the securing pin and to rest on the periphery of the securing pin. A segment angle of approx. 90 degrees has proven to be particularly advantageous, since this not only ensures reliable locking, but also enables the locking to be released again in a comparatively simple manner.

With regard to the securing axis, it has proven to be advantageous if it has a latching groove into which the securing element can be latched. 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 been found to be advantageous if the latching of the securing element can be manually released 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 slide off the axle holder when the door swings. With regard to the load on the securing element, it has been found to be advantageous if it is arranged outside of the flow of force 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 passed through the two hinge elements into the frame and thus past the securing element. The Si security element is therefore 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 axle holder. The bolt can be straight and pointed or chamfered at its ends, which facilitates the connection or assembly of both the safety tion element and the hinge eye simplified. Since the bolt 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 frictionally or form-fitting 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 been found to be advantageous if the hinge axis and the safety axis protrude from the axle holder. The hinge eye or the securing element can be arranged on the respective protruding parts. The hinge axis can extend upwards relative to the axis holder and the securing axis can extend downwards 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 on the frame side and the hinge axis is 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 been found with regard to the second hinge element as before geous if this is designed 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 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 enables the door to be 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 zen 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. Unlike 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. The hinge axis can rather 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 be connected to the first hinge element, in particular rotationally coupled. This rotary coupling allows 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. The hinge elements can be reliably coupled and secured with each other 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, the securing element can be plugged onto the securing axis and then rotated around the securing axis until the hedging element comes into contact with the first hinge element or with the door comes and can then engage with the hinge element or with the door accordingly. 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. To connect to the door, it can have mounting bolts on the inside, with which the safety element can engage. The mounting bolts can, for example, be welded or riveted to the inside of the door. In the reversed 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 hedging element can lock in accordance with the first hinge element or with the frame.

In an alternative embodiment, the securing element can also be coupled magnetically to rotate 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. When the latched position is reached, the latching arms can independently latch with the latching contour, as a result of which a reliable connection between the first hinge element and the securing element is ensured. The latching arms can be deformed in the elastic area 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. So far the fuse element is to be latched to the door or to the frame, Montagebol zen arranged on the door or on the frame can also have a corresponding latching contour that allows latching with the latching device of the fuse element. Also other rest Contours or a different arrangement on the frame and/or door are possible.

With regard to the configuration of the securing element, it has also proven to be advantageous if this 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 engage with the first hinge element, the recess allows the door to nevertheless have corresponding mounting bolts, which are then not used, at least for latching with the securing element. In this respect, the recess can be designed as a receiving bore. The door can have more mounting bolts than are actually required, which means that the same door can be used in different installation situations and therefore different mounting 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 to the frame, there is no risk of the two hinge elements unintentionally decoupling from one another again. Because the first time you close the door, the safety element is automatically locked. 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. A 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 locking 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 hung out of 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 latching device, provision can also be made, for example, for the two latching arms to be 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 bores which are adapted to the position of the mounting bolts on 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 Montageele element is arranged between the hinge eye and the door. The hinge eye can be connected to the mounting bolt of the door via a screw connection, so that the mounting element is then also 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 will. 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 make direct contact with it. This also goes hand in hand with a larger opening angle of the door, since the end of the door can hit the inner side of the stop support facing the door frame when it is opened to the maximum extent. The recess may have a rectangular shape and be part of the mounting element of the first hinge nierelements.

In a further 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 which does not impede the coupling process. The swing-out ramp simplifies door assembly. 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 be 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 turned away about the securing axis when the two hinge elements are coupled, ie during 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 close the security elements before the actual assembly of the door on the security axis assemble, which can speed up the assembly process as a whole. 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 left-hinged door or for a right-hinged door, different swing-out ramps can be used to that extent. 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 Ho rizontalflanke can thus serve as a contact surface for the fuse element or the hinge eye. If two swing-out ramps are provided, the securing element can correspondingly flank on one of the two horizontal flanks and the hinge eye can be arranged or rest on the other horizontal flank.

Furthermore, it has proven to be advantageous if the ramp flanks of the two swing-out ramps are turned 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 .

With regard to the object mentioned at the outset, a device is also proposed with a frame and a door that is pivotably connected to the frame via a hinge, the hinge being designed in the manner described above. This results in the advantages already described in the hin view of the hinge.

With regard to this device, it has proven to be advantageous if the door is pivotably connected to the frame via a number of hinges. Multiple hinges allow the door to support 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 the fuse elements with the door or with the first hinge element.

Furthermore, it has turned out 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 has and wherein different mounting bolts are used for a right stop and a left stop. 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.

Further details and advantages of the invention are to be described in more detail below with reference to the attached drawings of an exemplary embodiment. Show in it:

Door;

6a, 6b perspective views of the securing element during latching with the first hinge element; and FIGS. 7a, 7b perspective views of a securing element which can be latched with a mounting bolt of the door. In the illustration of Figs. 1a and 1b, a piece of a frame 30 is Darge provides, for example, part of a consist of several metal sheets can be the cabinet. A hinge element 2 is fastened to the frame 30 and essentially consists 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 fixed against rotation in the axle holder 2.1 and which is arranged at a distance from the frame 30 via the axle 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 shown in FIG. 1b. 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 via a screw connection to the door 20. The door 20 can be pivotably connected to the frame 30 via the two hinge elements 1, 2, so that the door 20 pivots about the axis of rotation D shown in FIG. 2b and extends centrally through the hinge axis 2.2, and is thus opened and closed can be.

The correspondingly coupled or connected position is shown in FIG. 2a. 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 axle 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 can then be pivoted with coupled to the frame 30. During this coupling process, the hinge eye 1.1 is placed on the hinge axis 2.2 from above, which also means that the door 20 is hung in the frame 30. In the corresponding position, the door 20 can then be pivoted relative to the frame 30 and can in this respect also be opened and closed, but the door 20 is not yet secured to the frame. This can also be lifted off the frame 30 in the reverse order. In the case of heavy and upright doors 20, this is generally not a major problem. 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 can be seen in the illustration in FIG. 2b.

The securing element 3 can be slipped onto the securing axis 2.3 in the axial direction from below until it has reached the position shown in FIG. 2c. One advantage of the securing element 3 is that no tools are required for assembly and that the connection to the securing axis 2.3 is so simple that assembly can even be carried out blindly. As can be seen in FIG. 2a, the securing pin 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 to the securing pin 2.4, so that in the plugged-on position according to FIG. 2c, the securing element 3 can no longer be easily removed from the securing pin 2.3. In order to enable a corresponding snap-in connection with the safety pin 2.3, the safety element 3 has a snap-in claw 3.3, which in the enlarged perspective detail views of Figs. 5a and 5b to recognize it. When attaching the fuse element 3 on the backup axis 2.3, the latching claw 3.3 is first swung out a bit and then deformed in the elastic range. As can be seen, for example, in FIG. 1a, the securing pin 2.3 has a pointed tip at its lower end, which makes it easier to attach the securing element 3 and therefore also to elastically deform the latching claw 3.3. When the securing element 3 is placed so far on the securing axis 2.3 that the latching claw 3.3 has reached the latching groove 2.4, the latching claw 3.3 automatically engages in the latching groove 2.4 and thus secures the Si securing element 3 on the securing axis 2.3.

Even in this latched and axially immovable position, the hedging element 3 is still freely rotatable relative to the securing axis 2.3. If the securing element 3 is plugged onto the securing axis 2.3, the two hinge elements 1, 2 are initially not yet 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 accordingly to the first hinge element 1, the securing element 3 must be pivoted about the securing axis 2.3 in the position shown in FIG. 2d. The connection of the securing element 3 to the first hinge element 1 is also effected via a latching 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 can be seen in the enlarged representation of FIGS. 6a and 6b. That

Securing element 3 has a locking device 3.1, the two locking arms 3.11 includes. If the securing element 3 is pressed from the position shown in FIG. 6a into the locking position shown in FIG. 6b, the two locking arms 3.11 are elastically deformed and then engage in the locking contour 1.5 of the first hinge element after the locking position has been reached 1 a. 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 . The securing element 3 is then rotationally coupled to the first hinge element 1 in this respect. 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 translational 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 4a to 4c can be seen. In the illustration of FIG. 4a, the door 20 was suspended 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 shown in FIG. 4b, the door 20 is still in a half-open position. However, the closing 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 in relation to the door 20 or in relation to the first Hinge element 1 . The first hinge element 1 then moves towards the fixed securing element 3 . When the door 20 has reached the closed position, the securing element 3 is engaged in the first hinge nierelement 1 and 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. FITS when the door 20 is connected to the frame 30 via several hinges 10, this auto-lock function leads to it a significant simplification of assembly, since by closing the door 20 all the securing elements 3 are locked simultaneously with the respective first hinge elements 1 who can.

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 about the axis of rotation D in the opposite direction, the latching device 3.1 and the latching contour 1.5 are disengaged. 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 required Lich to also 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 mounting bolt 21, which can be seen in FIG. 2a, 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 axial movement of the hinge elements 1, 2. In order to automate this, the first hinge element 1 has a swing-out ramp 1.4.

If the securing element 3 is, for example, in the position shown in FIG. 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 within the hinge eye 1.1, the swivel ramp 1.4 comes off at this point axial movement with the securing element 3 in contact and pushes it to the side. The securing element 3 is thus rotated about the securing axis 2.3 by the swing-out ramp 1.4 into a position in which it does not impede an axial movement of the hinge elements 1, 2.

The geometry of the swing-out ramp 1.4 essentially corresponds to that of a prism, and it has a ramp edge 1.41 and a horizontal edge 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 swung out accordingly when the door 20 is hung. The horizontal flank 1.42 extends essentially perpendicularly to the door 20 and serves as a bearing surface for the securing element 3 or for the hinge eye 1.1, as can be seen, for example, in the illustration in FIG. 2d.

According to the illustration in FIG. 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 doors 20 hinged on the left. In the figures, for example a right-hinged door 20 is shown. If the door 20 were to be hinged on the left, the first hinge element 1 would have to be rotated 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 correspondingly this swing-out ramp 1 .4 would then press the securing element 3 to the side when hanging.

As can also be seen, for example, in FIG. 2d, 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 receive the axle holder 2.1 when the door 20 is closed, as can be seen, for example, by comparing FIGS. 4a and 4c. 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. From the swivel ramps 1.4, the recess 1.3 and the two Rastkontu ren 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 which are arranged on the inside of the door and are each provided with a thread. The mounting element 1.6 has bores 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 initially rests flat on the door 20. 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- NEN door 20, the hinge eye 1.1 is mounted according to 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 engage with the first hinge element 1 at the mounting point 1.2 not occupied by the hinge eye 1.1 despite the mounting bolt 21, the securing element has a recess 3.2 into which the mounting bolt 21 not used for connection to the door can dip . This recess 3.2 can be seen, for example, in FIG. 5a. In this respect, the securing element 3 can be connected to one of the two latching contours 1.5 independently of the Mon daily bolt 21.

The two locking contours 1.5 of the first hinge element 1 and 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 locking connection with the securing element 3, depending on whether the hinge element 1 is used for a door 20 hinged on the right or left.

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 configured identically and both axes 2.2, 2.3 are also suitable in each case by corresponding Rastnu th 2.4 for locking with the securing element 3, can the same axis 2.2, 2.3 depending on the installation situation either as a hinge axis 2.2 or as a safety axis 2.3. Furthermore, this configuration also makes it possible 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 in an alternative configuration that is not shown

30

A further alternative configuration is shown in FIGS. 7a, 7b.

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 embodiment, but rather the mounting bolts 21 must have a corresponding latching contour 1.5. In principle, 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, 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. References:
