DETAILED DESCRIPTION OF THE INVENTION

(5) The invention is described in greater detail in the following text on the basis of exemplary embodiments of one embodiment of one variant of a vehicle door leaf 1 according to the invention on the basis of a vehicle door leaf frame 10 according to the invention for a rail vehicle (rail vehicle door leaf 1, rail vehicle door leaf frame 10). The invention is not restricted, however, to a variant of this type, to embodiments of this type and/or to the exemplary embodiments which are described in the following text, but rather is of more fundamental nature, with the result that the invention can be applied to all vehicles (see above). The drawing shows only those sections of a subject of the invention which are necessary for a comprehension of the invention.

(6) Furthermore, the description of the invention on the basis of the drawing relates in the following text to a width direction B or a width axis B, to a thickness direction D or a thickness axis D, and to a vertical direction H or a vertical axis H, and to a circumferential direction U of the vehicle door leaf frame 10 or the vehicle door leaf 1. Although the invention has been described and illustrated in greater detail by way of preferred exemplary embodiments, the invention is not restricted by way of the disclosed exemplary embodiments. Other variants can be derived herefrom and/or from the above (description of the invention), without departing from the scope of protection of the invention.

(7) FIG. 1 shows the vehicle door leaf 1, without at least one plug-in seal, a stowage shaft window and a mechanism for the latter, an interior trim panel, an exterior panel, a recess for a lock device and/or a bearing device, etc., based on the vehicle door leaf frame 10, two corner regions 11 of the vehicle door leaf frame 10 being shown in greater detail in FIGS. 2 (right-hand upper corner region 11 of FIGS. 1) and 3 (left-hand upper corner region 11 of FIG. 1). In accordance with the invention, the vehicle door leaf frame 10 is configured as a profile frame 10 which preferably has four frame hollow profiles 102, 102; 202, 202. Another number of frame hollow profiles 102, . . . ; 202, . . . ; . . . can possibly be used.

(8) In accordance with the invention, the frame hollow profiles 102, . . . ; 202, . . . ; . . . come from two or precisely two hollow profiles 100, 200 of different configuration, their cross sections (110, 120, 130, 140; 210, 220, 230, 240; cf., in particular, FIG. 3 with FIG. 4) being of different configuration, in particular, with regard to shape and size. In the present case, two horizontal, inner frame hollow profiles 102, 102 and two vertical, outer frame hollow profiles 202, 202 are used for the vehicle door leaf frame 10. It is of course possible to swap this, that is to say to use vertical, inner frame hollow profiles and horizontal outer frame hollow profiles.

(9) The following comments relate substantially only to a single inner frame hollow profile 102 and a single outer frame hollow profile 202 and a common corner region 11 of said two frame hollow profiles 102, 202. The following comments can be applied analogously, however, to the other frame hollow profiles 102, 202 (preferably two) and the other corner regions 11 (preferably three).

(10) The inner frame hollow profile 102 (cf. FIG. 3) has a base profile 110 with a preferably closed, mainly “rectangular” or mainly “square” cross section. Here, the cross section is “pentagonal”, a corner (plan view of the cross section: top left) of a rectangle or square being of beveled configuration (pentagonal, mainly rectangular cross section). That is to say, the base profile 110 is configured as a polygonal tube or a pentagonal tube with a mainly rectangular or square cross section. Here, rounded portions can of course also be provided. Other shapes, such as triangular, hexagonal, polygonal shapes, possibly with rounded portions; round shapes, etc., can of course be used.

(11) Furthermore, the base profile 110 of the inner frame hollow profile 102 preferably has three lug-shaped projections 120, 130, 140 which project away therefrom in the vertical direction H, each projection 120, 130, 140 preferably being configured as an extension of a side wall of the base profile 110, which side wall relates to said projection. All lug-shaped projections 120, 130, 140 preferably do not lie at least with a free section in a plane of that side wall of the base profile 110 which relates to the respective projection 120, 130, 140. Said sections are preferably arranged, however, parallel to the relevant side wall, to which they are preferably connected integrally (parallel offset).

(12) Thus, the base profile 110 has a preferably radially outer, front (outer side 18 of the vehicle) profile web 120 which is preferably recessed substantially completely from the relevant side wall of the base profile 110. The profile web 120 can have a seal edge or can be configured as a seal edge of this type. Said seal edge can have grooving. Furthermore, the base profile 110 has a preferably radially outer, rear (inner side 19 of the vehicle (cab, carbody)) profile web 130 which is preferably recessed merely in sections from the relative side wall of the base profile 110. The profile web 130 can have a seal edge or can be configured as a seal edge of this type. Said seal edge can likewise have grooving.

(13) Moreover, the base profile 110 has a preferably radially inner, front profile limb 140 which is preferably recessed substantially completely from the relevant side wall of the base profile 110. The profile limb 140 can have a seal edge or can be configured as a seal edge of this type. Said seal edge can once again likewise have grooving. The radially outer, front profile web 120 and the radially inner, front profile limb 140 preferably lie in one plane. Here, a respective seal edge serves preferably for receiving a plug-in seal 52, 53, 54 (cf. FIG. 4).

(14) Here, the outer frame hollow profile 202 (cf. FIG. 4) is configured with a substantially analogous shape with respect to the inner frame hollow profile 102, its preferably three lug-shaped projections 220, 230, 240 (radially outer, front profile web 220, radially outer, rear profile web 230, radially inner, front profile limb 240) preferably not projecting from it in the vertical direction H, however, but rather in the width direction B. Furthermore, all lug-shaped projections 220, 230, 240 preferably lie at least with a section, in particular completely, in a plane with that side wall of the base profile 210 which relates to the respective projection 220, 230, 240 and to which they are preferably connected integrally (no parallel offset). Furthermore, the radially outer, front profile web 220 and the radially inner, front profile 240 limb preferably lie in one plane.

(15) The outer frame hollow profile 202 is configured in such a way that the base profile 102 of the inner frame hollow 102, possibly including a bonded section, for example, of its outer, rear profile web 130 (cf. FIG. 3), can be received between two side walls of the outer frame hollow profile 202 with a clearance fit or a transition fit (cf. FIGS. 2 and 3). That is to say, the two frame hollow profiles 102, 202 are configured such that they can be plugged into one another with their longitudinal end sections. Said two frame hollow profiles 102, 202 which meet one another can be riveted and/or screwed to one another in their mutual overlaps (corner regions 11). Welded seams/welded spots can possibly be used in addition.

(16) Furthermore, mutual linear contact regions result between the profile webs 120, 220; 130, 230 (four) which meet one another and the profile limbs 140, 240 (two) which meet one another. In said regions, the two frame hollow profiles 102, 202 which meet one another are preferably fitted in a complementary manner, with the result that they configure seal edges which preferably run around substantially completely on the profile webs 120, 220; 130, 230 and have substantially no offset in the thickness direction D. It is possible, in particular, to dispense with one fitted connection or all fitted connections.

(17) The outer frame hollow profile 202 is preferably machined in its two corner regions 11 in such a way that (outer) radii 12, 13 (plug(-in) lugs 12, 13) are provided for the preferably substantially completely circumferential door seals 52, 53 ((plug-in) seals 52, 53). Furthermore, the outer frame hollow profile 202 and, in a corresponding manner thereto, the inner frame hollow profile 102 and, a second time, the outer frame hollow profile 202 and, in a manner which corresponds thereto, a center strut 40 (see below, alternative thrust plate 30, see below) are preferably machined in such a way that radii 14 (plug(-in) lugs 14) are provided there for the preferably substantially completely circumferential window seal 54 ((plug-in) seal 54). The plug-in lugs 12, 13, 14 can have grooving, in order to increase retention of the seals 52, 53, 54.

(18) In order that a (stowage shaft) window can be set up between the outer frame hollow profiles 202, 202, the possibly beaded center strut 40 is riveted and/or screwed onto the two frame hollow profiles 202, 202 at a corresponding level. A preferably beaded thrust plate 30 is riveted or screwed to the two outer frame hollow profiles 202, 202, the center strut 40 and the lower inner frame hollow profile 102 between the center strut 40 and the lower inner frame hollow profile 102. The center strut 40 can possibly be configured in one piece/integrally with the thrust plate 30. In addition or as an alternative to at least one bead, the thrust plate 30 can have at least one other reinforcing device.

(19) In all corner regions 11, a sealing compound can be introduced between the frame hollow profiles 102, 202 which meet one another there during the plugging together, in order that the vehicle door leaf frame 10 can be configured in a pressure-tight manner. The thrust plate 30 and/or the center strut 40 are/is preferably likewise provided with sealing compound on the vehicle door leaf frame 10. Moreover, sealing compound is possibly likewise provided between the thrust plate 30 and the center strut 40. In addition or as an alternative, the transitions between the components which meet one another (frame hollow profiles 102, 102; 202, 202—thrust plate 30—center strut 40) and/or the entire vehicle door leaf frame 10 (possibly on one side, outer side 18 (on the outside and/or on the inside)) can be sealed retroactively, possibly also additionally, with a coating, with the result that the vehicle door leaf 1 is pressure-tight even without an exterior panel.
