    DESCRIPTION OF THE INVENTION

    [0047] FIG. 1A-B show a hinge 1 in each case in a perspective view. The hinge 1 has a pin element 2 which comprises a, in this case, cylindrical hinge pin 3 extending along a pin axis A. At the opposing longitudinal ends of the hinge pin 3, the pin element 2 in each case has a fastening means in the form of a bore 4. By means of the bores 4, the pin element 2 can be fastened to a leaf, for example in the form of a door and/or a flap, or a base part, for example in the form of a frame, for example by screwing.

    [0048] In addition to the pin element 2, the hinge 1 has a pin receiving element 5. The pin receiving element 5 has on its front side a pin receiver 6 with an assembly opening 7 through which the hinge pin 3 can be inserted into the pin receiver 6 and removed from the pin receiver 6. Like the pin element 2, the pin receiving element 5 has two fastening means on its rear side in the form of bores 8 by means of which the pin receiving element 5 can be fastened to a leaf or a base part.

    [0049] A securing element 9 is held on the pin receiving element 5. In this case, the securing element 9 is held in the present case on a securing element axis 10 of the pin receiving element 5 extending at least substantially parallel to the pin receiver 6, which defines a securing pivot axis AS. Thus, the securing element 9 can be pivoted with respect to the pin receiving element 5 about the securing pivot axis AS in a guided manner. In addition, a spring means 11 in the form of a flexible wire is provided. The spring means 11 extends through two openings 12 of the pin receiving element 5 arranged on the opposing longitudinal sides of the securing element 9 and through an opening 13 of the securing element 9 not represented in FIG. 1A-B and arranged on the rear side of the securing element 9. In this case, the spring means 11 is bent over on the sides of the openings 12 of the pin receiving element 5 facing away from the securing element 9 and thus held in a simple manner on the pin receiving element 5.

    [0050] The hinge pin 3 is represented in an assembled position and the securing element 9 is represented in a release position in FIG. 1A. In the assembled position, the hinge pin 3 is arranged outside the pin receiver 6 such that in the represented and in this respect preferred exemplary embodiment, the pin element 2 and the pin receiving element 5 are unconnected. In the release position, the securing element 9 substantially releases the assembly opening 7 of the pin receiver 6 such that the hinge pin 3 can be inserted into the pin receiver 6 to establish a hinge connection by displacement relative to the pin receiving element 5 at least substantially perpendicular to the pin axis A. Thus, the hinge pin 3 can be adjusted from the assembled position represented in FIG. 1A to a pivot position represented in FIG. 1B. The securing element 9 can be adjusted from the release position represented in FIG. 1A by pivoting relative to the pin receiving element 5 about the securing pivot axis AS into a securing position represented in FIG. 1B.

    [0051] The hinge pin 3 is represented in the pivot position and the securing element 9 is represented in the securing position in FIG. 1B. In the pivot position, the hinge pin 3 is received in the pin receiver 6 of the pin receiving element 5 such that the pin element 2, and together with this, the hinge pin 3 can be pivoted relative to the pin receiving element 5 about the pin axis A. In this case, the securing element 9, adopting the securing position, partially closes the assembly opening 7 of the pin receiver 6 such that the hinge pin 3 is secured from an unintentional adjustment at least substantially perpendicular to the pin axis A out of the pin receiver 6. To detach the hinge connection, the securing element 9 can be adjusted from the securing position represented in FIG. 1B by pivoting about the securing pivot axis AS into the release position represented in FIG. 1A and the hinge pin 3 from the pivot position represented in FIG. 1B by displacement at least substantially perpendicular to the pin axis A into an assembled position, for example, the assembled position represented in FIG. 1A.

    [0052] FIG. 2A-B show a system 14 with a base part 15 in the form of a frame, a leaf 16 in the form of a door and the hinge 1 in a perspective view and a horizontal sectional view along the section plane IIB-IIB represented in FIG. 2A. In this case, the base part 15 and the leaf 16 are only represented in sections. In the represented and in this respect preferred exemplary embodiment, the pin element 2 of the hinge 1 is fastened to the leaf 16 via its bores 4 by means of two screws 17 and the pin receiving element 5 of the hinge 1 is fastened to the base part 15 via its bores 8 by means of two screws 18. Alternatively, the pin element 2 could also be fastened to the base part 15 and the pin receiving element 5 to the leaf 16.

    [0053] In the represented and in this respect preferred hinge 1, in addition to the pin receiving element 5, the securing element 9 also has a pin receiver 19 for partially receiving the hinge pin 3. In this case, the pin receiver 19 of the securing element 9 extends at least substantially parallel to the pin receiver 6 of the pin receiving element 5. The pin receiver 19 of the securing element 9 has a circular arc-shaped cross-section perpendicular to its longitudinal extension.

    [0054] The hinge pin 3 is represented in the pivot position and the securing element 9 in the securing position in FIG. 2A-B. In this case, the hinge pin 3 is received in the pin receiver 6 of the pin receiving element 5 and partially in the pin receiver 19 of the securing element 9 such that the leaf 16 fastened to the pin element 2 can be pivoted about the pin axis A with respect to the base part 15 fastened to the pin receiving element 5. Thus, the leaf 16 can be pivoted with respect to the base part 15 between an open position represented in FIG. 2A and represented dashed in FIG. 2B and a closed position represented in FIG. 2B. In this case, the leaf 16 in the closed position closes an access 20, which is delimited laterally by the base part 15. In the open position, the leaf 16 releases the access 20.

    [0055] In the securing position, a restoring force FRS returning the securing element 9 to the securing position acts on the securing element 9. The restoring force FRS returning the securing element 9 to the securing position presses the securing element 9 against a stop 21 of the pin receiving element 5, which is designed in the present case as a cylindrical axis extending parallel to the securing pivot axis AS. In this way, it is prevented that the securing element 9 is unintentionally pivoted out of the securing position and reaches a position in which it releases the assembly opening 7 of the pin receiver 6 such that the hinge pin 3 can come out of the pin receiver 6. The restoring force FRS is effected by the spring means 11 and is selected such that engagement and disengagement can take place without tools and without pressing any buttons.

    [0056] If the leaf 16 is in the closed position, for example, the hinge connection can be detached. To this end, the hinge pin 3, together with the leaf 16 fastened thereto, can be displaced with respect to the pin receiving element 5 and the base part 15 fastened thereto, at least substantially perpendicular to the pin axis A from the pivot position represented in FIG. 2a-B to an assembled position in which the hinge pin 3 is arranged outside the pin receiver 6. In this case, the securing element 9 is pivoted by the contact with the hinge pin 3 against the restoring force FRS returning the securing element 9 to the securing position from the securing position represented in FIG. 2A-B and then pivoted to the release position in which the securing element 9 substantially releases the assembly opening 7 of the pin receiver 6.

    [0057] FIG. 3A-B show the system 14 in a perspective view and a horizontal sectional view along the section plane IIIB-IIIB represented FIG. 3A. In this case, the hinge pin 3 is represented in an assembled position and the securing element 9 is represented in the release position. In the assembled position, the hinge pin 3 is arranged outside the pin receiver 6 of the pin receiving element 5 and the pin receiver 19 of the securing element 9 such that the hinge connection between the base part 15 and the leaf 16 is separated.

    [0058] In the release position, the securing element 9 substantially releases the assembly opening 7 of the pin receiver 6 such that the hinge pin 3 can be inserted into the pin receiver. In this case, a restoring force FRF returning the securing element 9 to the release position acts on the securing element 9, which presses the securing element 9 against the pin receiving element 5. In this way, it is prevented that the securing element 9 is unintentionally pivoted out of the release position and reaches a position in which it closes the assembly opening 7 of the pin receiver 6 so far that the insertion of the hinge pin 3 into the pin receiver 6 is impeded by the securing element 9. The restoring force FRF is also effected by the spring means 11.

    [0059] In order to establish the hinge connection, the hinge pin 3, together with the leaf 16 fastened thereto, can be adjusted by displacement with respect to the pin receiving element 5 at least substantially perpendicular to the pin axis A from the assembled position represented in FIG. 3A-B to the pivot position represented in FIG. 2A-B. In this case, the securing element 9 is pivoted by the contact with the hinge pin 3 against the restoring force FRF returning the securing element 9 to the release position from the release position represented in FIG. 3A-B and then pivoted in the direction of the restoring force FRS returning the securing element 9 to the securing position to the securing position represented in FIG. 2A-B.

    [0060] Pivoting the securing element 9 from the release position represented in FIG. 3A-B to the securing position represented in FIG. 2A-B and back is thus carried out via an intermediate position, wherein between the release position and the intermediate position, the restoring force FRF returning the securing element 9 to the release position acts on the securing element 9 and between the securing position and the intermediate position, the restoring force FRS returning the securing element 9 to the securing position. In the intermediate position, the securing element 9 is in an unstable equilibrium in which neither a force in the direction of the securing position nor a force in the direction of the release position acts on the securing element 9. This is achieved by the spring means 11 being untensioned in the intermediate position and only generating a restoring force FRF, FRS in one or the other direction when the hinge pin 3 engages or disengages.

    [0061] FIG. 4A-B show an alternative hinge 22 in each case in a perspective view, which is designed similarly to the hinge described above. For this reason, the same components also have the same reference numerals. However, there is a significant difference in terms of the mechanism for securing the hinge pin 3 in the pin receiver 6. Thus, in addition to a securing element 23, which is also held on the securing element axis 10 of the pin receiving element 5 so as to be pivotable about the securing pivot axis AS in the represented and in this respect preferred hinge 22, a locking element 24 is provided. The locking element 24 is held on a locking element axis 25 of the pin receiving element 5, which defines a locking pivot axis AV extending at least substantially parallel to the pin receiver 6. Thus, the locking element 24 can be pivoted about the locking pivot axis AV in a guided manner with respect to the pin receiving element 5. In this case, the locking element 24 has a pressure surface 26 for actuating the locking element 24. The pressure surface 26 is designed such that the locking element 24 can be pivoted about the locking pivot axis AV by applying a compressive force on the pressure surface 26 at least substantially perpendicular to the pressure surface 26.

    [0062] Furthermore, a spring means 27 in the form of a flexible wire is provided. The spring means 27 extends through the two openings 12 of the pin receiving element 5, which are arranged on the opposing longitudinal sides of the locking element 24 in the represented and in this respect preferred exemplary embodiment. In addition, the spring means 27 extends through an opening 28 of the locking element 24 not represented in FIG. 4A-B and arranged on the rear side of the locking element 24. In this case, the spring means 27 is bent over in the present case on the sides of the openings 12 of the pin receiving element 5 facing away from the locking element 24 and thus held on the pin receiving element 5.

    [0063] In FIG. 4A, the hinge pin 3 is represented in an assembled position, the securing element 23 in a release position and the locking element 24 in an unlocking position. In order to establish a hinge connection, the hinge pin 3 can be displaced from the assembled position represented in FIG. 4A at least substantially perpendicular to the pin axis A to the pivot position represented in FIG. 4B and the securing element 23 can be pivoted from the release position represented in FIG. 4A about the securing pivot axis AS to a securing position represented in FIG. 4B. The locking element 24 can then be adjusted from the unlocking position represented in FIG. 4A by pivoting about the locking pivot axis AV to a locking position represented in FIG. 4B.

    [0064] In FIG. 4B, the hinge pin 3 is represented in the pivot position, the securing element 23 in the securing position and the locking element 24 in the locking position. In the locking position, the locking element 24 blocks the pivoting of the securing element 23 from the securing position to the release position in a positive-locking manner. In this way, it can be particularly reliably avoided that the securing element 23 unintentionally reaches a position in which it releases the assembly opening 7 of the pin receiver 6 such that the hinge pin 3 can come out of the pin receiver 6.

    [0065] In order to detach a hinge connection established by means of the hinge 22, the locking element 24 can be pivoted from the locking position represented in FIG. 4B about the locking pivot axis AV to the unlocking position represented in FIG. 4A by applying a compressive force on the pressure surface 26. The securing element 23 can then be pivoted about the securing pivot axis AS from the securing position represented in FIG. 4B to the release position represented in FIG. 4A and the hinge pin 3 can be displaced at least substantially perpendicular to the pin axis A from the pivot position represented in FIG. 4B to an assembled position, for example, the assembled position represented in FIG. 4A.

    [0066] FIG. 5A-B show an alternative system 29 comprising the hinge 22 in a perspective view and a horizontal sectional view along the section plane VB-VB represented in FIG. 5A. Since the represented system 29 is designed similarly to the system described above, the same components also have the same reference numerals. Like the securing element of the previously described hinge, the securing element 23 of the represented and in this respect preferred hinge 22 also has a pin receiver 30. In this case, the pin receiver 30 of the securing element 23 extends parallel to the pin receiver 6 of the pin receiving element 5 and the pin receiver 30 of the securing element 23 has a circular arc-shaped cross-section perpendicular to its longitudinal extension.

    [0067] In FIG. 5A-B, the hinge pin 3 is represented in the pivot position, the securing element 23 in the securing position and the locking element 24 in the locking position. The locking element 24 engages in a positive-locking manner into a locking receptacle 31 of the securing element 23 and thus blocks the pivoting of the securing element 23 about the securing pivot axis AS from the securing position to the release position in a positive-locking manner. In this case, the pretensioned spring means 27 extending through the opening 28 of the locking element 24 and the openings 12 of the pin receiving element 5 effects a restoring force FRV returning the locking element 24 to the locking position, which presses the locking element 24 against the securing element 23. Thus, the locking element 24 rests on the securing element 23 in the direction of the restoring force FRV returning the locking element 24 to the locking position.

    [0068] In the depicted and in this respect preferred hinge 22, the securing element 23 is also spring-loaded, namely by a pretensioned spring means 32, which is designed in the present case as an elbow spring. In this case, the elbow spring is held on the securing element axis 10 of the pin receiving element 5, wherein the one leg of the elbow spring is supported on the pin receiving element 5 and the other leg of the elbow spring is supported on the securing element 23. In this way, the spring means 32 effects a restoring force FRF returning the securing element 23 to the release position such that the securing element 23 rests on the locking element 24 in the direction of this restoring force FRF.

    [0069] In FIG. 5B, the leaf 16 is represented in the closed position. In the closed position, the leaf 16 blocks the pivoting of the locking element 24 about the locking pivot axis AV from the represented locking position to the unlocking position in a positive-locking manner. To detach the hinge connection, the leaf 16 can be adjusted from the closed position about the pin axis A to an open position represented in FIG. 5A and represented dashed in FIG. 5B, in which the leaf 16 partially releases the access 20. In this open position, the leaf 16 is arranged such that the locking element 24 can be pivoted from the locking position represented in FIG. 5A-B to the unlocking position against the restoring force FRV of the spring means 27 returning the locking element 24 to the locking position. The hinge pin 3, together with the leaf 16, can then be displaced from the pivot position represented in FIG. 5A and represented dashed in FIG. 5B perpendicular to the pin axis A to an assembled position in which the hinge pin 3 is arranged outside the pin receiver 6. In this case, the securing element 23 is pivoted from the securing position represented in FIG. 5A-B about the securing pivot axis AS to the release position.

    [0070] FIG. 6A-B show the system 29 in a perspective view and a horizontal sectional view along the section plane VIB-VIB represented in FIG. 6A, wherein the hinge pin 3 is represented in an assembled position, the securing element 23 in the release position and the locking element 24 in the unlocking position. The locking element 24 is arranged outside the locking receptacle 31. In this case, the locking element 24 is pressed against the securing element 23 by the restoring force FRV returning the locking element 24 to the locking position, which is effected by the wire-shaped spring means 27. Thus, the locking element 24 rests on the securing element 23 in the direction of the restoring force FRV returning the locking element 24 to the locking position. In addition, the securing element 23 is pressed against the locking element 24 by the restoring force FRF returning the securing element 23 to the release position, which is effected in the present case by the spring means 32 designed as an elbow spring, such that the securing element 23 rests on the locking element 24 in the direction of the restoring force FRF returning the securing element 23 to the release position.

    [0071] In order to establish the hinge connection, the hinge pin 3, together with the leaf 16, can be displaced at least substantially perpendicular to the pin axis A from the assembled position represented in FIG. 6A-B to the pivot position represented in FIG. 5A-B. In this case, the securing element 23 is pivoted by the contact with the hinge pin 3 against the restoring force FRF returning the securing element 23 to the release position, which is effected by the spring means 32 designed as an elbow spring, from the release position represented in FIG. 6A-B to the securing position represented in FIG. 5A-B. The locking element 24 is then automatically pivoted by the restoring force FRV returning the locking element 24 to the locking position, which is effected by the wire-shaped spring means 27, from the unlocking position represented in FIG. 6A-B about the locking pivot axis AV to the locking position represented in FIG. 5A-B.

    [0072] FIG. 7A-B show a further hinge 33 in each case in a perspective view which is similar to the hinge described above. For this reason, the same components also have the same reference numerals. A significant difference, however, is the design of the mechanism for locking the securing element 23 in the securing position. As with the previously described hinge, a locking element 34 is also held on the pin receiving element 5 in the represented and in this respect preferred hinge 33. In this case, however, the locking element 34 is held on two locking element axes 35 of the pin receiving element 5 extending at least substantially parallel to the pin receiver 6 such that the locking element 34 can be pivoted about a locking pivot axis AV, which is arranged at least substantially perpendicular to the pin axis A of the hinge pin 3 in relation to the alignment in the pivot position. The locking element axes 35 can, for example, be formed from a spring wire. As an alternative to retaining the locking element 34 by the two locking element axes 35, the locking element 34 could also be held by means of a special contour of the corresponding/adjoining components, wherein fixed stops can also be provided (e.g. +−90° from the closed position).

    [0073] The locking element 34 has a shaped section 36, which is designed in the present case as a square. A correspondingly designed tool 37 can be placed on the shaped section 36, which is designed in the present case as a square spanner. The locking element 34 can then be pivoted about the locking pivot axis AV in a simple manner by means of the tool 37. In the represented and in this respect preferred exemplary embodiment, the shaped section 36 has a marking in the form of an arrow, which indicates the respective position in which the locking element 34 is located.

    [0074] In FIG. 7A, the hinge pin 3 is represented in an assembled position, the securing element 23 in the release position and the locking element 34 in an unlocking position. In the release position, the securing element 23 releases the assembly opening 7 of the pin receiver 6 so far that the hinge pin 3 can be displaced at least substantially perpendicular to the pin axis A from the assembled position represented in FIG. 7A to the pivot position represented in FIG. 7B. As a result, the securing element 23 is pivoted from the release position represented in FIG. 7A about the securing pivot axis AS to the securing position represented in FIG. 7B. The locking element 34 can then be adjusted, for example, by means of the tool 37 from the unlocking position represented in FIG. 7A by pivoting about the locking pivot axis AV to a locking position represented in FIG. 7B.

    [0075] In FIG. 7B, the hinge pin 3 is represented in the pivot position, the securing element 23 in the securing position and the locking element 34 in the locking position. In the locking position, the locking element 34 blocks the pivoting of the securing element 23 from the securing position to the release position in a positive-locking manner. In order to detach a hinge connection established by means of the hinge 33, the locking element 34 can be pivoted about the locking pivot axis AV, for example, by means of the tool 37 from the locking position represented in FIG. 7B to the unlocking position represented in FIG. 7A. The hinge pin 3 can then be moved at least substantially perpendicular to the pin axis A from the pivot position represented in FIG. 7B to an assembled position, for example, the assembled position represented in FIG. 7A. In this case, the securing element 23 is pivoted about the securing pivot axis AS from the securing position represented in FIG. 7B to the release position represented in FIG. 7A.

    [0076] FIG. 8A-B show a further system 38 comprising the hinge 33 in a perspective view and a horizontal sectional view along the section plane VIIIB-VIIIB represented in FIG. 8A. Since the represented system 38 is designed similarly to the system described above, the same components also have the same reference numerals. In FIG. 8A-B, the hinge pin 3 is represented in the pivot position, the securing element 23 in the securing position and the locking element 34 in the locking position. In the locking position of the locking element 34, a lug 39 of the locking element 34 engages in the locking receptacle 31 of the securing element 23, whereby the pivoting of the securing element 23 about the securing pivot axis AS from the securing position to the release position is blocked in a positive-locking manner. In this case, the securing element 23 is pressed against the locking element 34 by the restoring force FRF returning the securing element 23 to the release position, which is effected by the spring means 32 designed as an elbow spring, such that the securing element 23 rests on the locking element 34 in the direction of the restoring force FRF returning the securing element 23 to the release position.

    [0077] In the represented and in this respect preferred exemplary embodiment, the leaf 16 has an unlocking recess 40 designed in the present case in a circular shape. The tool 37 of the hinge 33 can be placed on the shaped section 36 of the locking element 34 through the unlocking recess 40 in the closed position of the leaf 16 represented in FIG. 8B, in which the leaf 16 closes the access 20. Thus, the locking element 34 can be pivoted about the locking pivot axis AV between the locking position and the unlocking position by means of the tool 37 in the closed position of the leaf 16.

    [0078] To detach the hinge connection between the base part 15 and the leaf 16, the locking element 34 can, for example, in the closed position of the leaf 16 by means of the tool 37, be pivoted from the locking position represented in FIG. 8A-B about the locking pivot axis AV to the unlocking position. In this case, the lug 39 of the locking element 34 is pivoted out of the locking receptacle 31 of the securing element 23 such that the locking element 34 releases the pivoting of the securing element 23 about the securing pivot axis AS from the securing position to the release position. The hinge pin 3, together with the leaf 16, can then be displaced from the pivot position represented in FIG. 8A-B at least substantially perpendicular to the pin axis A to an assembled position in which the hinge pin 3 is arranged outside the pin receiver 6. In this case, the securing element 23 is pivoted from the securing position represented in FIG. 8A-B about the securing pivot axis AS to the release position at least substantially releasing the assembly opening 7 of the pin receiver 6.

    [0079] FIG. 9A-B show the system 38 in a perspective view and a horizontal sectional view along the section plane IXB-IXB represented in FIG. 9A, wherein the hinge pin 3 is represented in an assembled position, the securing element 23 in the release position and the locking element 34 in the unlocking position. In the release position, the securing element 23 is pressed against the locking element 34 by the restoring force FRF returning the securing element 23 to the release position, which is effected by the spring means 32 designed as an elbow spring. Thus, the securing element 23 rests on the locking element 34 in the direction of the restoring force FRF returning the securing element 23 to the release position.

    [0080] In order to establish the hinge connection between the base part 15 and the leaf 16, the hinge pin 3, together with the leaf 16, can be displaced at least substantially perpendicular to the pin axis A from the assembled position represented in FIG. 9A-B to the pivot position represented in FIG. 8A-B. In this case, the securing element 23 is pivoted by the contact with the hinge pin 3 against the restoring force FRF returning the securing element 23 to the release position about the securing pivot axis AS from the release position represented in FIG. 9A-B to the securing position represented in FIG. 8A-B. Subsequently, for example, in the closed position of the leaf 16 by means of the tool 37, the locking element 34 can be pivoted about the locking pivot axis AV from the unlocking position represented in FIG. 9A-B to the locking position represented in FIG. 8A-B.

    [0081] The two locking element axes 35 can, unlike as represented in FIG. 7A to FIG. 9B, also be extended so that their ends protrude upwards and/or downwards out of the pin receiving element 5. In addition, it can be provided that the ends are connected to one another above and/or below the pin receiving element 5, whereby a torsion-proof design results (U-shape or O-shape). Preferably, the ends are also inclined in the direction of the locking pivot axis AV in the direction of the leaf 16, i.e. “outwards”. As a result, the leaf 16, in its closed position, hits the inclined ends of the locking element axes 35 and elastically deforms them (the pretension path can, for example, be 2 mm to 3 mm). In this way, the locking element axes 35 act as a spring and generate a pretension with respect to the leaf 16 (e.g. a door leaf), which leads to the leaf 16 automatically springing open a little bit after unlocking, whereby it can be gripped more easily by hand and opened further. This is a particular advantage for completely enclosed doors.
