Abstract

A drainage device, in particular for a shaft window, contains a vertically movable valve part which has a valve head and an immovable valve part valve which has a drain which can be dosed by the valve head in a closed position. The vertically movable valve part is arranged on a counterweight.

First claim

The invention claimed is:

1. A shaft window drainage device, comprising:
a vertically movable valve part having a valve head;
an immovable valve part having a drain, said drain being closed by said valve head; and
a vertically movable counterweight of a shaft window, said vertically movable valve part is fastened in said vertically movable counterweight such that, if the shaft window is opened, said vertically movable valve part is raised simultaneously with said vertically movable counterweight and is separated from said immovable valve part, and therefore said valve head is spaced apart from said drain and thus said drain is opened.

2. The shaft window drainage device according to claim 1 , further comprising:
a spring; and
a guide rod, said valve head is connected to said guide rod in a closing direction of the shaft window drainage device and, in a closed state of the shaft window drainage device, said valve head is pressed against said drain relative to a position of said vertically movable counterweight by said spring.

3. The shaft window drainage device according to claim 2 , further comprising a sleeve, said guide rod is received and guided by said sleeve, wherein said guide rod or said sleeve being received in a vertically movable manner in a receiving portion of said vertically movable counterweight.

4. The shaft window drainage device according to claim 2 , wherein said guide rod has a detent on a side opposite said valve head.

5. The shaft window drainage device according to claim 1 , wherein said drain has a sealing surface for receiving said valve head in regions in a closed state of the shaft window drainage device.

6. The shaft window drainage device according to claim 1 , wherein said drain is a fluid-conducting connection through a window guide frame.

7. A rail vehicle shaft window having at least one open position and a closed position, the rail vehicle shaft window comprising:
a movable sliding frame;
a window pane disposed in said movable sliding frame;
a window guide frame;
a vertically movable counterweight, said movable sliding frame being disposed in said window guide frame and connected to said vertically movable counterweight;
a drain being introduced in a lower region of said window guide frame, a vertically movable valve part having a valve head being oriented with respect to said drain and disposed for closing or for opening said drain;
an immovable valve part having said drain, said drain being closed by said valve head; and
said vertically movable valve part being fastened to said vertically movable counterweight such that, if the rail vehicle shaft window is opened, said movable valve part is raised simultaneously with said vertically movable counterweight and is separated from said immovable valve part, and therefore said valve head is spaced apart from said drain and thus said drain is opened.

8. The window according to claim 7 ,
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.

9. The window according to claim 7 , wherein said drain is a pipe or a hose and is disposed in a positionally fixed manner on said window guide frame.
