[0020] The present invention relates to a distribution cabinet 20 comprising a base body 30, a door leaf 40, and a hinge body 50. The hinge body 50 comprises at least one hinge element 60, which is movably held in the base body 30 along a translation axis T and has at least one pivot axis S connected to the door leaf 40. The door leaf 40 is pivotable about the pivot axis S.

[0021] The distribution cabinet 20 according to the exemplary embodiment can be designed as a box that can be closed by means of the door leaf 40 and in which, for example, fuse and switching elements for distributing electrical energy in the area of ​​a low-voltage network are housed. The fuse and switching elements can be accessible to an installer or user through a cabinet opening when the door leaf 40 is open. The distribution cabinet 20 according to the exemplary embodiment can be suitable for installation in a cavity wall and / or for flush-mounted installation.

[0022] The distribution cabinet 20 according to the exemplary embodiment has a hinge body 50 composed of two hinge elements 60. The hinge elements 60 are arranged on opposite sides of the hinge body 50.

[0023] The pivot axis S can extend substantially orthogonally to the translation axis T.

[0024] The pivot axis S may further extend substantially parallel to the door leaf 40 and / or the cabinet opening. The translation axis T may extend substantially orthogonal to the door leaf 40 in a closed position of the door leaf 40 and substantially orthogonal to the cabinet opening. A closed position of the door leaf 40 is shown, for example, in the Figures 1 and 12 reproduced.

[0025] The hinge element 60 can be held in the base body 30 of the distribution cabinet 20 in a form-fitting manner such that only the translational movement along the translation axis T of the hinge element 60 is permitted. This prevents, for example, a tilting of the hinge element 60. When the door leaf 40 is opened, the hinge element 60 is moved in a translational movement that runs parallel to the translation axis T from a minimum position to a maximum position of the hinge element 60. The minimum position is particularly Figure 12 and the maximum position especially in Figure 18 shown.

[0026] The door leaf 40 comprises at least one projection 42 which extends substantially parallel to the pivot axis S. The base body 30 comprises at least one substantially elliptical guide surface 32, along which the projection 42 is suitable for sliding during an opening or closing operation of the door leaf 40. According to the present embodiment, the base body 30 can comprise two parallel elliptical guide surfaces 32 which form an elliptical guide groove. This configuration is particularly evident from the Figures 14 , 16 and 18 visible.

[0027] According to the exemplary embodiment, the door leaf 40 comprises two projections 42 for each hinge element 60, which are preferably arranged opposite one another and / or collinearly.

[0028] When the distribution cabinet 20 is opened by pivoting the door leaf 40, the elliptical guide surface 32 and / or the elliptical guide groove convert the relative rotational movement of the door leaf 40 relative to the hinge element 60 into the translational movement of the hinge element 60. Thus, according to the exemplary embodiment, for each hinge element 60, one of the two projections 42 can be guided by a guide surface 32, and the other of the two projections 42 can be guided by the guide groove formed by two guide surfaces 32.

[0029] The door leaf 40 is guided by the guide surface 32 during the movement from the closed position of the door leaf 40 to the intermediate position of the door leaf 40. During the movement from the intermediate position of the door leaf 40 to the open position of the door leaf 40, the projections 42 are located outside the guide groove and / or are not in contact with the guide surface 32.

[0030] In the intermediate position, the hinge element 60 is arranged higher in the receptacle 34 than in the minimum position.

[0031] Due to the translational movement along the translational axis T of the hinge element 60, the pivot axis S is also displaced along the translational axis T away from an interior of the distribution cabinet 20. Due to this displacement, the pivot axis S moves from an interior of the distribution cabinet 20 to an exterior area beyond the plane in which the cabinet opening lies. Thus, in an open position of the door leaf 40, an opening angle of the door leaf 40 of up to approximately 190° is possible, in particular without any contact between the door leaf 40 and the cover 31. Such an open position of the door leaf 40 is in Figure 17 reproduced.

[0032] The pivot axis S can be formed by at least one pin 62, wherein the door leaf 40 includes an opening 44 in which the pin 62 is received. The pin can also be referred to as the hinge of the door leaf 40.

[0033] The hinge element 60 according to the present embodiment can comprise two such pins 62, which are arranged on opposite wings 61 of the hinge element 60. Correspondingly, the door leaf 40 has two openings 44. To insert the pins 62 into the openings 44, for example, during assembly of the distribution cabinet 20, the wings 61 can be pressed together in a direction parallel to the pivot axis S. For this purpose, the wings 61 are arranged on the hinge element 60 in a flexible manner and spaced apart from one another by a gap 65.

[0034] In order to prevent the pins 62 from accidentally slipping out of the openings 44, the two wings 61 can be blocked against compression by a blocking element 63.

[0035] A receptacle 34 can be formed in the base body 30, in which the hinge element 60 is held so as to be movable along the translation axis T, wherein the receptacle 34 is delimited by at least one side wall 36 extending substantially parallel to the translation axis T.

[0036] The receptacle 34 according to the exemplary embodiment has a rectangular cross-section and is formed by four such side walls 36. Two opposite side walls 36 of the four side walls 36 are arranged orthogonally to the pivot axis S. The two remaining, likewise mutually opposite, side walls 36 are arranged parallel to the pivot axis S.

[0037] The hinge element 60 can comprise a locking projection 64. The hinge element 60 can further comprise at least one retaining web 67, which is preferably arranged opposite the locking projection 64 on the hinge element 60. The locking projection 64 and the retaining web 67 hold the hinge element 60 in a form-fitting manner in the receptacle. Thus, in particular, the locking projection 64 can come into contact with a locking surface 33 of the receptacle 34 and the retaining web 67 can come into contact with a retaining surface 35 of the cover 31 in the maximum position of the hinge element 60 in order to prevent the hinge element 60 from sliding out of the receptacle 34 in the translation direction T beyond the maximum position. This embodiment is particularly Figure 18 reproduced.

[0038] Such a locking projection 64, particularly in conjunction with the retaining web 67, facilitates the assembly of the distribution cabinet 20 and, in particular, the reception of the hinge element 60 in the receptacle 34. When the hinge element 60 is inserted into the receptacle 34, the locking projection 64 is pressed inward. As soon as the hinge element 60 is inserted into the receptacle 34, the locking projection 64 can spring back, whereby the hinge element 60 is held in the receptacle in a form-fitting manner, enabling a translational movement in the translation direction T from the minimum position to the maximum position.

[0039] The hinge element 60 may further comprise additional lateral locking projections 64a, which in the maximum position of the hinge element 60 may rest against corresponding locking surfaces of the cover 31.

[0040] At least one recess 38 can be formed in the side wall 36, in which the pin 62 is received in a closed position of the door leaf 40. This embodiment is particularly Figure 6 This design enables secure closing of the distribution cabinet 20 by means of the door leaf 40.

[0041] The hinge element 60 may comprise at least one tongue portion 66 and the door leaf 40 may comprise at least one groove 46, wherein the tongue portion 66 is received in the groove in an intermediate position of the door leaf 40 in order to hold the door leaf 40 in the intermediate position. This embodiment is particularly in Figure 16 This design allows the door leaf 40 to be easily secured in the intermediate position.

[0042] The base body 30 may comprise a cover 31 in which the hinge element 60 is held so as to be movable along the translation axis T, wherein the receptacle 34 is preferably formed in the cover 31.

[0043] The distribution cabinet 20 according to the application allows the door to be opened at an angle of approximately 190° relative to a plane in which the cabinet opening is arranged. The hinge body 50 can be formed on the cover 31 of the distribution cabinet 20.
