19. The window according to claim 18, wherein said drain has a sealing surface; and further comprising a spring, wherein in a closed state of said drain, said valve head is pressed against said sealing surface of said drain by said spring.

20. The window according to claim 18, wherein said drain is a pipe or a hose and is disposed in a positionally fixed manner on said window guide frame.

Description

[0033] The above-described properties, features and advantages of this invention and the manner in which they are achieved will become clearer and more clearly comprehensible by the explanation of the greatly simplified schematic illustrations of preferred exemplary embodiments below. In the illustrations

[0034] FIG. 1 shows a schematic illustration of a shaft window according to one embodiment of the invention,

[0035] FIG. 2 shows a detailed view II of the shaft window from FIG. 1, and

[0036] FIG. 3 shows a schematic sectional illustration III-III of the shaft window from FIG. 2.

[0037] In the figures, the same structural elements each have the same reference numbers.

[0038] FIG. 1 shows a schematic illustration of a shaft window 1 according to one embodiment of the invention. The shaft window 1 is illustrated in an open position.

[0039] The shaft window 1 has a window guide frame 2. A sliding frame 4 with a window pane 6 is arranged in a vertically movable manner in the window guide frame 2. The shaft window 1 is illustrated in an open position of the window pane 6.

[0040] The sliding frame 4 together with the window pane 6 is connected to a counterweight 8 via cable pulls (not illustrated) and deflecting pulleys such that a dead weight of the sliding frame 4 and of the window pane 6 during manual operation is compensated for.

[0041] The counterweight 8 is likewise arranged here in a vertically movable manner in the window guide frame 2 and so as to be guided by the window guide frame 2.

[0042] According to the exemplary embodiment, in a lower region of the counterweight 8, a movable valve part 10 is integrated in the form of a spring-tensioned valve wedge in the counterweight 8.

[0043] An immovable valve part 12 is arranged on a lower portion of the window guide frame 2. The immovable valve part 12 is positioned under the movable valve part 10 in the sliding direction or in the closing direction of the window 1.

[0044] FIG. 2 shows a detailed view II of the shaft window from FIG. 1. The window 1 is illustrated here in a closed position, as a result of which the counterweight 8 takes up a vertically lowermost position within the window sliding frame 2.

[0045] A receiving portion 14 for receiving the valve head 16 and a valve sleeve 18 is introduced in a lower region of the counterweight 8. By this means, the valve head 16 can be fastened in a technically simple manner to the counterweight 8 by means of a detent 20.

[0046] The detent 20 is realized here in the form of a nut 20 on a guide rod 22 configured as a threaded rod. The threaded rod 22 is fastened on one side to the valve head 16, extends through the sleeve 18 and the receiving portion 14 of the counterweight 8 and is fixed at a second end of the receiving portion 14 by the nut 20.

[0047] Owing to the lowermost position of the counterweight 8, the valve head 16 of the movable valve part 10 is pressed into the immovable valve part 12 such that no liquid or gas can escape through the immovable valve part 12.

[0048] FIG. 3 illustrates a schematic sectional view III-III of the shaft window 1 from FIG. 1 and FIG. 2. In particular, an exemplary design of the drainage device 10, 12 is shown in detail here.

[0049] The drainage device consists of a movable valve part 10, which is positioned on the receiving portion 14 of the counterweight 8, and of an immovable valve part 12, which is arranged on a lower portion of the window guide frame 2.

[0050] The movable valve part 10 has a valve head 16 which is connected to a guide rod 22 on the end side. The valve head 16 can be composed here of a metal or a plastic and is preferably formed conically.

[0051] The guide rod 22 extends through a sleeve 18 which is screwed against the valve head 16 by the nut 20. The sleeve 18 serves, for example, as a plain bearing in the receiving portion 14 of the counterweight 8. In the closed state of the window 1, the valve head 16 is pressed by a lower region of the receiving portion 14 against the immovable valve part 12 via a spring 23. The valve head, preferably valve cone, is thus pressed thereagainst with a defined, adaptable force which is smaller than the weight force of the counterweight.

[0052] The immovable valve part 12 has a drain 24 for conducting water out of the window guide frame 2. The drain 24 is positioned in a positionally fixed manner in the lower part of the window guide frame 2 and has a sealing surface 26 which is oriented vertically in the direction of the counterweight 8. The sealing surface 26 serves for receiving the valve head 16 and is designed here as a conically shaped recess in the drain 24.
