Abstract

An anti-climbing protection apparatus for a rail vehicle includes at least one buffer supported by an energy absorption element connected to a rail vehicle frame. In order to permit such a protection apparatus to be produced economically, to reliably prevent overriding and to be comparatively easy to retrofit, a bearing element is fastened to an end of the energy absorption element facing away from the vehicle frame. The bearing element supports an anti-climbing protection device at an end thereof protruding in a vertical direction from the buffer. In the event of a crash, a horizontally oriented stop, in cooperation with the front of the rail vehicle, permits an anti-climbing protection element of the anti-climbing protection device to be brought from the stop into an anti-climbing protection position extending outward over the buffer.

First claim

The invention claimed is:

1. An anti-climbing protection apparatus for a rail vehicle, the anti-climbing protection apparatus comprising:
an energy absorption element connected to a vehicle frame of the rail vehicle and having an end facing away from the vehicle frame;
at least one buffer supported by said energy absorption element;
a bearing element fastened to said end of said energy absorption element facing away from the vehicle frame, said bearing element having an end projecting vertically from said at least one buffer;
an anti-climbing protection device supported by said end of said bearing element projecting vertically from said at least one buffer, said anti-climbing protection device including an anti-climbing protection element; and
a horizontally aligned stop moving said anti-climbing protection element interacting with the front of the rail vehicle into an anti-climbing protection position extending over said at least one buffer in the event of a crash.

2. The anti-climbing protection apparatus according to claim 1 , wherein said stop is fastened in a vicinity of the front of the rail vehicle.

3. The anti-climbing protection apparatus according to claim 1 , wherein said stop is fastened to said anti-climbing protection device.

4. The anti-climbing protection apparatus according to claim 1 , wherein said stop and said anti-climbing protection device are disposed above said energy absorption element.

5. The anti-climbing protection apparatus according to claim 4 , wherein:
said bearing element includes a rocker joint disposed below said energy absorption element and an end disposed above said energy absorption element;
said anti-climbing protection device includes a pivoting bracket having two bracket arms and being pivotably mounted via one of said bracket arms on said rocker joint of said bearing element; and
said pivoting bracket is supported at said end of said bearing element disposed above said energy absorption element permitting the other of said bracket arms to be moved into said anti-climbing protection position by said stop on the rail vehicle in the event of a crash.

6. The anti-climbing protection apparatus according to claim 1 , wherein said stop and said anti-climbing protection device are disposed below said energy absorption element.

7. The anti-climbing protection apparatus according to claim 1 , wherein said anti-climbing protection device includes a guide, and said anti-climbing protection element is a slider being held in said guide, being horizontally displaceable in said guide and having an end facing said stop and projecting from said guide.

8. The anti-climbing protection apparatus according to claim 7 , wherein said slider is arrested against unwanted slipping in an initial operating position.

9. The anti-climbing protection apparatus according to claim 7 , which further comprises a break-off connection holding said slider in said guide.

10. The anti-climbing protection apparatus according to claim 7 , wherein said slider has an end facing away from said stop and a horizontal rib at said end facing away from said stop.

11. The anti-climbing protection apparatus according to claim 7 , wherein said slider or said slider element has an end facing away from said stop and a catch at said end.

12. The anti-climbing protection apparatus according to claim 1 , which further comprises:
a slider part facing said stop;
said anti-climbing protection element being a slider element connected in a longitudinally offset manner through one rated break point to said slider part;
said slider part being connected through a further rated break point to said guide; and
said one rated break point being stronger than said further rated break point.

13. The anti-climbing protection apparatus according to claim 12 , wherein said slider element and said slider part have a constant thickness over their length and are correspondingly wedge-shaped in sections.

14. The anti-climbing protection apparatus according to claim 12 , wherein said slider part widens in a wedge shape towards said stop and said slider element widens in a wedge shape away from said stop.

15. The anti-climbing protection apparatus according to claim 12 , wherein said slider or said slider element has an end facing away from said stop and a catch at said end.
