DETAILED DESCRIPTION

[0052] FIGS. 1-3 show schematic sectional representations of an example of a car corner bracket 1 according to the invention in different planes. The car corner bracket 1 comprises two receptions 4, 5 suitable for inserting panel elements not explicitly shown in the figure.

[0053] The receptions 4, 5 are equipped with retainers 7a, 7b for receiving abutment elements for defining a position and/or fixing panel elements, the abutment elements and the panel elements not being explicitly shown in the FIGS. 1-3. One of the retainers 7a is arranged in a front wall 9 of one of the reception 4.

[0054] The car corner bracket 1 comprises a first outer flank 10 and a second outer flank 11, including a corner angle and a first inner flank 12 and a second inner flank 13, including the corner angle . The first inner flank 12 and the first outer flank 10 as well as the second inner flank 13 and the second outer flank 11 are arranged in parallel and have a distance d therebetween. The first inner flank 12, the first outer flank 10 and an end part 14 of the second outer flank 11 form a first reception 4. The second inner flank 13, an end part 15 of the first inner flank 12 and a second part 19 of the second outer flank 11 form a second reception 5. As can be seen in FIG. 1, the second outer flank 11 consists of two portions: the end part 14 (as a first part) and the second part 19.

[0055] A retainer 7a (see FIG. 2) is arranged in the end part 14 of the second outer flank 11, which forms the front wall 9 of the first reception 4. A further retainer 7b (see FIG. 3) is arranged in the first outer flank 10. The end part 15 of the first inner flank 12, which forms the front wall 16 of the second reception 5, comprises a hole 17 being aligned with the retainer 7b.

[0056] FIG. 4 shows a schematic representation of an example of a car corner bracket 1 in a perspective view. The car corner bracket 1 comprises a lug 20 with a long hole 21.

[0057] FIG. 5 shows a schematic representation of an example of a car corner member 23 in a partial sectional and partial perspective view. The car corner member 23 comprises a car corner bracket 1 and abutment elements 8. The retainers 7a, 7b comprise insert nuts 18, for engaging a surface structure 24, in this case an outer thread of an abutment element 8. The receptions 4, 5 are suitable for accommodation of panel elements 6 of equal thickness 22. A screw having a rivet head forms the abutment element 8. After the panel element 6 is inserted in the car bracket element 1 and placed in the right position, the abutment element 8 can be screwed in until the front end 27 of the abutment element reaches a front face 26 of the panel element 6 so that the panel element is fixed in position. In the example shown in FIG. 5 a longitudinal groove 25 is located in the front face 27 of the panel element 6. It is, however, also conceivable that the panel element 6 has a plane front face.

[0058] FIG. 6 shows a schematic representation of a part of an elevator car arrangement 28 in a perspective view. The elevator car arrangement 28 comprises a car corner member 23 and panel elements 6. Retainers 7a, 7b for receiving abutment members 8 abutting panel elements 6 of different walls are arranged alternating one upon the other.

[0059] The car bracket element 1 is fixed to a lateral support 33 and to a rear support 34. The lateral support 33 and the rear support 34 define the position of the car bracket element 1 and hence the dimension of the elevator car 29 as can be seen in FIG. 7 which shows a schematic representation of an example of an elevator car 29 in a sectional view. The elevator car 29 comprises four elevator car arrangements 28, joining side wall elements 2. The elevator car 29 comprises four car corner brackets 1 for adjusting the depth 31 and the width 30 of the elevator car 29 and the width 32 of the door opening.

[0060] 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.
