DETAILED DESCRIPTION
(11) FIG. 1 shows the embodiment of a hinge 1 according to the present embodiments in the assembled state in a mobile toilet 2 for a caravan with a toilet lid 3 as well as a toilet bowl 4 with a bowl casing 5. Hinge 1 is formed of several members and has three pairs of hinge members 6. Said hinge members 6 each are formed as one piece with the components of the toilet 2. One pair of hinge members 6 is formed as one piece with the toilet lid 3. A further pair of hinge members 6 is formed as one piece with the toilet bowl 4 as a hinge receiving facility 7 for arranging the remaining hinge members at the toilet bowl 4. It is also conceivable to form the hinge receiving facility 7 separately from the toilet bowl 4 to also allow the use in customary toilets with a ceramic toilet bowl.
(12) Moreover, FIG. 1 shows the embodiment of a damping device 8 according to the present embodiment. One pair of such damping devices 8 is installed in the hinge 1 for retrofitting. Furthermore, an additional pair of damping devices 8 is shown. The damping devices 8 each have a substantially cylindrical main body 9 and a substantially rectangular rotational body 10 that are rotatably mounted to each other.
(13) Furthermore, the damping device 8 according to the present embodiments has a bung-like projection 11 that is formed substantially rectangular and extends in a longitudinal direction of the cylindrical main body 9.
(14) FIG. 2 shows the mobile toilet 2 with a raised lid 3. The mobile toilet 2 has a toilet seat 12.
(15) FIG. 3 shows that the hinge 1 according to the embodiment illustrated in FIG. 1 additionally comprises a pair of hinge members 6 that are formed as one piece with the toilet seat 12. Hinge 1 has a pivot axis S, with the attached toilet seat 12 and toilet lid 3 being pivotably supported at the toilet bowl 4 relative to said pivot axis S by means of the hinge 1.
(16) In addition, FIG. 3 shows that the hinge 1 according to the inventive embodiments has two opposite receiving areas 13-1, 13-2, a first left-sided receiving area 13-1 and a second right-sided receiving area 13-2, that each are formed to receive a supplementary damping device 8. The receiving areas 13-1, 13-2 are accessible also in the assembled state of the hinge by means of mounting openings 14. The hinge members 6 are engaged with each other.
(17) FIG. 4 shows an enlarged section of the left area of the hinge 1 according to FIG. 3. The first left receiving area 13-1 of the hinge 1 has three receptions A, B, C, with the first reception A being assigned to the toilet bowl 4, the second reception B being assigned to the toilet seat 12, and the third reception C being assigned to the toilet lid 3. The second reception B is arranged to the hinge member 6 that is formed as one piece with the toilet seat 12. For receiving a damping device 8 for damping the lowering movement of the toilet seat 12 the second reception B is formed for the form-closed reception of the rotational body 10 of the damping device 8. A first reception A that is rotation-symmetrical relative to the pivot axis S is arranged to the hinge member 6 that is formed as one piece with the toilet bowl 4. In said first reception A the correspondingly formed cylindrical main body 9 of the damping device 8 formed according to the embodiments can be arranged form-closed. However, the third reception C arranged to the hinge member 6 that is formed as one piece with the toilet lid 3 is not configured for an operative connection with the damping device 8.
(18) Moreover, FIG. 4 shows that the hinge members 6 and the receptions A, B, C, respectively have integrated engaging means 15. In this case, the engaging means 15 are rotation-symmetrically formed relative to the pivot axis S of the hinge, which makes the engaged hinge members 6 rotatable. In the assembling position the engaging means 15 of the outer hinge members 6 in the form of annular projections engage with corresponding engaging means 15 of the respective inner hinge members 6 in the form of circular grooves 17. The engaging means 15 each are formed at the edges of the receptions A, B, C of the hinge members 6.
(19) FIG. 5 shows an arrangement of a hinge 1 according to the present embodiments illustrated in FIG. 1, FIG. 3, and FIG. 4 and two damping devices 8 according to the embodiment illustrated in FIG. 1. The right-sided second receiving area 13-2 also has three receptions A, B, C each assigned to toilet bowl 4, toilet seat 12 and toilet lid 3. The hinge members 6 in the right area of the hinge 1 according to the embodiments are formed to receive a damping device 8 for damping the lowering movement of the toilet lid 3. For that, the reception C of hinge member 6 that is formed as one piece with the toilet lid 3 is formed for the form-closed reception of the rotational body 10 of the damping device 8. The reception B of hinge member 6 that is formed as one piece with the toilet seat 12 is not configured for the form-closed reception of the rotational body 10. The right-sided hinge member 6 that is formed as one piece with the toilet bowl 4 has a reception A for the form-closed reception of the cylindrical main body 9 of the damping device 8. In this way, an operative connection of the damping device 8 with the toilet lid 3 can be realized.
(20) As illustrated in FIG. 5, the damping devices 8 each have a rotational axis R. The cylindrical main bodies 9 of the damping devices 8 are rotation-symmetrical, the rotational bodies 10 are formed symmetrically to said rotational axis R. For insertion of the damping devices 8 into the receiving areas 13 of the hinge 1 according to the present embodiments the rotational bodies 10 of the damping devices 8 are directed towards the mounting opening 14. Furthermore, the rotational axes R of the damping devices 8 align with the pivot axis S of the hinge 1.
(21) FIG. 6 shows an arrangement of the embodiment of the hinge 1 illustrated in FIG. 1 and FIG. 3 to FIG. 5 with two installed damping devices 8 according to the embodiment illustrated in FIG. 1 and FIG. 5. The damping devices 8 are arranged in the receptions A, B, C of the respective receiving areas 13-1, 13-2 of the hinge 1, with the receiving areas 13-1, 13-2 and the damping devices 8 corresponding such that the respective rotational axes R are congruently directed with the pivot axis S of the hinge 1. The main bodies 9 of the damping facilities 8 each are form-closed fixed in the two receptions A that are assigned to the toilet bowl. The damping device 8 on the left side of the hinge 1 is in operative connection with the toilet seat 12. For that, rotational body 10 of the damping device 8 arranged on the left side is form-closed configured in the reception B of the hinge member 6 that is formed as one piece with the toilet seat 12. On the other side, the damping device 8 on the right side is in operative connection with the toilet lid 3. The rotational body 10 of the right-sided damping device 10 is form-closed arranged in the receiving area C of the hinge member 6 that is formed as one piece with the toilet lid 3.
(22) FIG. 7 shows a side elevation of the first receiving area 13-1 of the arrangement according to FIG. 6. The hinge members 6 that are formed as one piece with the toilet bowl 4 each have two parallel walls 18 spaced to each other. The walls 18 are spaced such that reception A has a groove-like recess 19 for receiving the bung-like projection 11 of the damping facility, cf. FIG. 4. The recess 19 leads to the respective mounting opening 14.
(23) FIG. 8 shows an enlarged section of the above-mentioned arrangement according to FIG. 7. FIG. 7 and FIG. 8 show that the cylindrical main body 9 and the bung-like projection of the damping device 8 are form-closed arranged in the reception A and the groove 19 of the hinge member 6 that is formed as one piece with the toilet bowl 4.
