Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The invention will be explained in more detail below with reference to a drawing which simply represents a preferred exemplary embodiment, in which is shown:

[0032] FIG. 1A—1D: a hinge according to the invention in different assembly positions and swivel positions in perspective view,

[0033] FIG. 2: a system according to the invention with a frame, a door and the hinge from FIG. 1A—FIG. 1D in perspective view, and

[0034] FIG. 3A—3F: the system according to the invention from FIG. 2 in different swivel positions in perspective view.

DESCRIPTION OF THE INVENTION

[0035] FIG. 1A and FIG. 1B show a hinge 1 according to the invention for detachably connecting a door to a frame in a perspective view. The hinge 1 has a frame part 2, a door part 3, a hinge pin 4 and a locking element 5. The locking element 5 is arranged on the frame part 2 and the hinge pin 4 is arranged on the frame part 2. Unlike in FIG. 1A and FIG. 1B, the arrangement could also be reversed; the locking element 5 could therefore be arranged on the door part 3 and the hinge pin 4 could be arranged on the frame part 2. The locking element 5 is held swivelably on the frame part 2 so that the locking element 5 can be swivelled relative to the frame part 2 about a swivel axis. The locking element 5 can be adjusted between a locking position (FIG. 1B) and a release position (FIG. 1A). In contrast, the hinge pin 4 is rigidly connected to the door part 3 in the case of the hinge 1 represented.

[0036] The hinge pin 4 has a pin axis A, which corresponds to the longitudinal axis of the hinge pin 4 for the hinge 1 represented. In addition, the hinge pin 4 has a conical adjustment surface 6 at its two longitudinal ends, which tapers in the direction of the associated longitudinal end of the hinge pin 4. Thus, the adjustment surfaces 6 in the represented and in this respect preferred exemplary embodiment each form an angle of approx. 35° with the pin axis A. Between the two adjustment surfaces 6, the hinge pin 4 also has two locking grooves 7, each of which are designed circumferentially around the hinge pin 4. The frame part 2 has a pin receiver 8, which is designed in a sleeve shape, in particular cylindrically and serves to receive the hinge pin 4 in itself. The pin receiver 8 has a recess 9 into which the locking element 5 can engage.

[0037] The frame part 2 and the door part 3 can be moved relative to one another along the pin axis A between a swivel position (FIG. 1B) and an assembly position (FIG. 1A). In the swivel position (FIG. 1B), the hinge pin 4 of the door part 3 is pushed into the pin receiver 8 of the frame part 2, in the assembly position (FIG. 1A), the hinge pin 4 is, in contrast, arranged outside the pin receiver 8.

[0038] The door part 3 has a contact surface 10 in the region between the two locking grooves 7 on its outer side, by means of which the door part 3 can be placed on a door (not represented in FIG. 1A and FIG. 1B). In order to be able to fasten the door part 3 in a simple manner on the door resting on the contact surface 10, the door part 3 also has a fastening element in the form of a borehole 11. The door part 3 can for example be screwed to the door via this borehole 11. Likewise, the frame part 2 has two boreholes 11 via which the frame part 2 can for example be screwed to the frame.

[0039] The frame part 2 has a closure receiver 12 and the door part 3 has a closure element 13. Alternatively to this, the frame part 2 could have a closure element 13 and the door part 3 could have a closure receiver 12. The closure element 13 engages into the closure receiver 12 in the closed position of the frame part 2 and of the door part 3 by way of the closure receiver 12 and the closure element 13.

[0040] FIG. 1C and FIG. 1D also show a hinge 1 according to the invention for detachably connecting a door to a frame in a perspective view. The regions of the hinge 1 already described in connection with FIG. 1A and FIG. 1B are provided in FIG. 1C and FIG. 1D with corresponding reference numerals. A difference with the configuration of the hinge 1 shown in FIG. 1A and FIG. 1B is that, in the case of the configuration of the hinge 1 shown in FIG. 1C and FIG. 1D, both the frame part 2 and the door part 3 have been rotated (rotation by 180°). In this way, it is possible to fasten a door both on the left side of a frame and to the right side of a frame using the hinge 1. The ability to use the hinge 1 on both sides is achieved in that both the frame part 2 and the door part 3 are designed in a mirror-symmetrical manner (i.e. they have one symmetry plane). In particular, the door part 3 has a hinge pin 4, which extends in two opposing directions (along the pin axis A) and the frame part 2 has two pin receivers 8 suitable for this purpose, into which the hinge pin 4 can be pushed from two opposing sides. FIG. 1C shows the hinge 1 in the assembly position and the locking element 5 in the release position and FIG. 1D shows the hinge 1 in the swivel position and the locking element 5 in the locking position.

[0041] In FIG. 2 is a system 14 according to the invention with a frame R, a door T and the hinge 1 from FIG. 1A—FIG. 1D in perspective view. The regions of the hinge 1 already described in connection with FIG. 1A to FIG. 1D are also provided in FIG. 2 with corresponding reference numerals. Both the frame R and the door T are only represented in sections. The frame part 2 is screwed to the frame R and the door part 3 is screwed to the door T. The configuration and position of the hinge 1 corresponds approximately to that in FIG. 1B, the hinge 1 is thus represented in the swivel position and the locking element 5 is represented in the locking position. In the swivel position represented, the frame part 2 and the door part 3 can be swivelled relative to one another about the pin axis A between an open position and a closed position. In the locking position also represented, the movement of the frame part 2 and of the door part 3 relative to one another along the pin axis A is blocked by the locking element 5.

[0042] FIG. 3A to FIG. 3F show the system 14 according to the invention from FIG. 2 in different swivel positions in perspective view. The regions of the hinge 1 already described in connection with FIG. 1A to FIG. 2 are also provided in FIG. 3A to FIG. 3F with corresponding reference numerals. In FIG. 3A to FIG. 3F, the hinge 1 is continuously in the swivel position, the hinge pin 4 of the door part is therefore always pushed into the pin receiver 8 of the frame part 2.

[0043] FIG. 3A shows the hinge 1 in an open position in which the locking element 5 is in the release position, i.e. it does not engage into the recess 9 of the pin receiver 8. This situation may occur, for example, immediately after the door has been “mounted”, i.e. immediately after the hinge pin 4 has been pushed into the pin receiver 8. FIG. 3B shows the hinge from FIG. 3A in a sectioned view. In the sectioned view, it is particularly clear that the locking element 5 with its hook-shaped end does not yet engage into the recess 9 of the pin receiver 8 and thus cannot yet block the locking groove 7 of the hinge pin 4.

[0044] FIG. 3C shows the hinge 1 in a closed position in which the locking element 5 is in the locking position, i.e. the locking element 5 engages into the recess 9 of the pin receiver 8. This situation may occur, for example, after door T has been locked for the first time. FIG. 3D shows the hinge from FIG. 3C in a sectioned view. In the sectioned view, it is particularly clear that the locking element 5 with its hook-shaped end engages into the recess 9 of the pin receiver 8 and can thus block the locking groove 7 of the hinge pin 4. When swivelling the frame part 2 and the door part 3 from the open position (FIG. 3A, FIG. 3B) to the closed position (FIG. 3C, FIG. 3D), the door T has adjusted the locking element 5 from the release position to the locking position. The locking element 5 is therefore automatically pressed into the locking position (“locked position”) when the door T is closed, whereby it can be ruled out that the hinge 1 accidentally remains in an unlocked position.

[0045] FIG. 3E shows (like FIG. 3A) the hinge 1 in an open position in which the locking element 5 (unlike FIG. 3A) is in the locking position, i.e. the locking element 5 engages into the recess 9 of the pin receiver 8. This situation may occur, for example, after the door T has been mounted and after the hinge 1 has been locked (e.g. by the first closing of the door T described above). FIG. 3E thus represents the correct operating condition. FIG. 3F shows the hinge from FIG. 3E in a sectioned view. In the sectioned view, it is particularly clear that the locking element 5 with its hook-shaped end engages into the recess 9 of the pin receiver 8 and can thus also continue to block the locking groove 7 of the hinge pin 4.
