[0002] Fixing device and method for fixing a window pane of a window for a rail vehicle and window for a rail vehicle
[0003] The present invention relates to a fixing device for fixing a window pane of a window in a door leaf for a rail vehicle, to a window for a rail vehicle and to a method for fixing a window pane of a window in a door leaf for a rail vehicle by means of such a fixing device.
[0004] For example, special requirements may apply for securing window panes in rail vehicle door leaves. Traditionally, a window pane can be secured in a rail vehicle window using adhesive or simply a rubber profile. It would also be conceivable to use a different adhesive, for example, one with a shorter curing time.
[0005] Against this background, it is the object of the present invention to provide an improved fixing device for fixing a window pane of a window in a door leaf for a rail vehicle, an improved window for a rail vehicle and an improved method for fixing a window pane of a window in a door leaf for a rail vehicle by means of such a fixing device.
[0006] This object is achieved by a fixing device for fixing a window pane of a window in a door leaf for a rail vehicle, by a window for a rail vehicle and by a method for fixing a window pane of a window in a door leaf for a rail vehicle by means of such a fixing device according to the main claims.
[0007] According to embodiments, in particular, a window pane can be fixed in a door leaf for a rail vehicle in a profile element, for example a rubber profile, by means of a fastening device, for example by means of at least one screw. In other words, a window pane assembly or fixing can be implemented in particular by applying common processes to replace special processes, such as gluing, or to replace disadvantageous methods. Such assembly or fixing of window panes in door leaves for rail vehicles can in particular also enable implementation in series production. Thus, according to embodiments, for example, adhesive or other adhesives, and thus material-to-material connections, can be dispensed with to fix a window pane of a window in a door leaf for a rail vehicle.In this case, the fastening device, such as at least one fixing screw, can be or become covered by a profile element, in particular a fixing rubber profile, of the fixing device itself and thus be invisible to passengers of the rail vehicle.
[0008] Advantageously, according to embodiments, in particular, assembly time can be shortened, protection against vandalism can be improved, and the window pane can be quickly replaced directly in the rail vehicle. Compared with fixing by means of a material bond, such an adhesive-free fixing of the window pane or fixing without a material bond according to embodiments can, for example, also advantageously eliminate the need for certification of the bonding process for rail transport and the curing time for the adhesive, so that the window pane can be quickly and easily replaced directly in the rail vehicle. Compared with fixing solely by means of a rubber profile, a combined fixing according to embodiments can, in particular, ensure a flat orA flush surface can be obtained, whereby a rubber profile protruding from the mounting surface can be avoided and the window pane can be replaced directly in the rail vehicle.
[0009] A fixing device for fixing a window pane of a window in a door leaf for a rail vehicle is presented, wherein the fixing device comprises a profile element, a window profile element and a fixing device, wherein the fixing device is designed to fix the profile element and the window profile element to one another by means of a positive fit and additionally or alternatively by means of a frictional fit, wherein the profile element is formed from an elastic material, wherein the profile element has a recessed section for enclosing an edge region of the window pane, an attachment section for attaching a part of the fixing device to the profile element by means of a positive fit, a cover section for covering the fixing device and a connecting section for connecting the cover section to the window profile element by means of a positive fit,wherein the cover portion is arranged between the attachment portion and the connecting portion, wherein the window profile element has an arranging portion for arranging a further part of the fastening device and a receiving portion for receiving the connecting portion of the profile element.,
[0010] The profile element can also be referred to as a fixing profile or fixing rubber profile. The window profile element can also be referred to as a window profile. The enclosing can represent a connection by form-fitting. The arranging can represent a connection by form-fitting. The cover section and the connecting section of the profile element can be bendable relative to the recess section and the attachment section of the profile element in order to make the fastening device accessible. The recess section, the attachment section, and the cover section of the profile element can extend along and additionally or alternatively parallel to a main extension plane of the window pane.

Such an embodiment offers the advantage that the fastening of the profile element and the window profile element to each other can be achieved in a robust, reliable, and easily detachable manner through positive locking and, additionally or alternatively, frictional locking.
[0013] Furthermore, when the profile element and the window profile element are fastened to one another, the cover section of the profile element can be arranged in alignment with a cover section of the window profile element. The cover section can be arranged adjacent to the receiving section. The receiving section can be arranged between the cover section and the arrangement section. Advantageously, when the profile element and the window profile element are fastened to one another, the cover section can form a flat or flush surface with a cover section of the window profile element when the connecting section is received in the receiving section.
[0014] In addition, the window profile element can have an outer contact section for contacting an outer sheet of a wall of the door leaf for the rail vehicle surrounding the window, and an inner contact section for contacting an inner sheet of the wall of the door leaf for the rail vehicle surrounding the window. The contact sections can be arranged on opposite sides of the window profile element. The outer sheet can face an area surrounding the rail vehicle. The inner sheet can face an interior or passenger area of the rail vehicle.
