DETAILED DESCRIPTION

[0065] FIG. 1 shows a perspective view of a connecting device 1 and a wall element 10, before the wall element 10 is suspended. FIGS. 2 and 3 show perspective views of a wall element arrangement 20 with connecting device 1 and suspended wall element 10. FIG. 4 shows a detailed view of two wall element arrangements 20 in sectional and top view.

[0066] The wall element 10 in the mounted state covers the bare wall 40 of an elevator car that is formed, for example, from a frame construction 41. The connecting device 1 comprises a rail element 2 with a first leg 3 and a second leg 4. The second leg 4 has, for example, tabs 8 that are designed as mounting surfaces 5 for a wall element 10.

[0067] The mounting surface 5 has first holes 6 for suspending a wall element 10 and second holes 7 for accommodating a fastening element 11 for connecting with the wall element 10. The second holes 7 are provided with an internal thread 18, for example. The first leg 3 comprises third holes 9 for receiving a fastening element 12 for connecting with the bare ceiling. The first leg 3 preferably faces away from the bare wall 40, so that the connecting device 1 can be mounted from the interior of the elevator car outward (see also FIGS. 5a, 5b).

[0068] The wall element 10 has suspension elements 13 at an edge 19 which faces upwardly in the mounted state for engaging into the first hole 6 of the connecting device 1. A suspension element 13 preferably comprises a vertical leg 21, from which a horizontal leg 22 extends outwardly in the direction of the bare wall 40. The horizontal legs 22 can be pushed easily into the first holes 6 during the mounting of the wall element 10 until they abut the mounting surface 5, wherein the wall element 10 is positioned and aligned.

[0069] In addition, the suspension element 13 preferably has holes 14 for receiving a fastening element 11, in this case a screw, with which the wall element 10 can be screwed to the connecting device 1. The fastening elements 11 are guided through the holes 14 in the suspension element and through the holes 7 in the second leg 4 of the connecting device 1, wherein they engage in the interior threads 18.

[0070] The wall elements 10 can comprise a plate 15 with integrated suspension elements 13. The plates 15 preferably have lateral edges 16 formed at an angle that face the bare wall 40. The angled lateral edges 16 of adjacent plates 15 in the mounted state rest approximately adjacent to each other. The wall elements 10 can comprise a stiffening layer 17 that is applied to the side of plate 15 facing toward the bare wall 40 of the car.

[0071] FIG. 5a shows a perspective view of a bare ceiling 30 with connecting device 1 seen from the interior of the elevator car and FIG. 5b shows a detailed view of it. The connecting device 1 is arranged on the bare ceiling 30 from below until the first leg 3 rests on the bare ceiling 30. Threaded holes 31 are provided in the bare ceiling 30, for example, that align with the holes 9 in the first leg 3. The connecting device 1 can then be screwed to the bare ceiling 30 from the interior of the elevator car with fastening elements 12, in this case screws. For each of the three bare walls 40 that have no elevator door, each is provided with one connecting device 1, in particular, that extends across the width 32 of the bare wall 40, or bare ceiling 30 and can respectively receive a plurality of wall elements 10.

[0072] The connecting devices 1 extend into the corners 38 of the bare ceiling 30. The connecting devices 1 have in particular holes 43 at one end 39 in which the first leg 3 of the next connection device 1 is located in the mounted state.

[0073] FIG. 6 shows a schematic representation of an example of a wall element 10 with a suspension profile 23 and a wall support 24. The wall elements 10 have suspension profiles 23 that are applied to the side of the wall elements 10 facing a bare wall 40 of an elevator car. The suspension profiles 23 are formed as angle strips with a horizontal leg strip 25 and a vertical leg strip 26.

[0074] During mounting, the vertical leg strip 26 pushes behind the clip profile 27 of a wall support 24 attached to the bare wall 40. Finally, the horizontal leg strip 25 remains on the clip profile 27. The wall elements 10 thus hang on the connecting devices 1 and on the wall supports 24.

[0075] FIG. 7a shows a perspective view of examples of two bare walls 40 with wall supports 24, in this case clip strips, seen from the interior of the elevator car. FIG. 7b shows a detail of this. The wall supports 24, in this case clip strips, have holes 24A for receiving screws 28. The holes 24A correspond to holes 29 that are provided in the bare walls 40 and have an internal thread. By means of the screws 28, the wall supports 24, in this case clip strips, can be screwed firmly to the bare walls 40, meaning from the interior of the elevator car. The direction of installation of the wall supports 24 is indicated by the large arrow in FIG. 7a.

[0076] FIG. 8 shows a schematic view of an example for an interior 42 of an elevator car indicated in this case with 100. Shown are two bare walls 40 and a subfloor 50. The bare walls 40 are covered with wall elements 10. The wall elements 10 are attached to the bare walls 40 from the interior of the elevator car 100, suspended with suspension elements 13 in a connecting device 1 and suspended with suspension profiles 23 on wall supports 24.

[0077] The wall elements 10 can have fastening tabs 34 on their lower edges 33 facing the subfloor 50, with which they can be secured to a fastening tab 35 provided on the subfloor 50. The fastening tabs 34 can have holes not explicitly shown and the fastening strip 35 can have holes not explicitly shown with internal threads so that the wall elements 10 can also be screwed firmly to the lower edge 33.

[0078] FIG. 9 shows a perspective view of examples of wall element arrangements 20. The wall element arrangements 20 comprise connecting devices 1 and wall elements 10. Protective strips 36 and hand rails 37 can also be mounted on the mounted wall elements 10.

[0079] In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
