## Abstract

Anti-climbing device for a rail vehicle includes a baffle plate, wherein a plurality of mutually parallel protruding first formations are arranged along a linear path on the baffle plate, and a plurality of mutually parallel protruding second formations are arranged along a linear path on the baffle plate and are orientated normally with respect to the first formations, where the extent of the second formations over the face of the baffle plate is smaller than the extent of the first formations over the face of the baffle plate, and where the first formations, at intersection locations of the formations, each have a recess in which the extent of the first formation is reduced.

## Claims

### Claim 1

An anti-climbing device for a rail vehicle comprising:
a baffle plate;
a plurality of mutually parallel protruding first formations arranged along a linear path on the baffle plate;
a plurality of mutually parallel protruding second formations arranged on the baffle plate along another linear path and orientated normally with respect to the first formations;
wherein an extent of the second formations over a face of the baffle plate is smaller than an extent of the first formations over the face of the baffle plate; and
wherein at intersection locations of the first and second formations the first formations each have a recess in which the extent of the first formations is reduced.

### Claim 2 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the extent of the first formation in a region of the recesses is reduced to the extent of the second formations.

### Claim 3 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the extent of the first formations in the region of the recesses is reduced to a lower value than the extent of the second formations.

### Claim 4 (depends on 1)

The anti-climbing device as claimed claim 1, wherein the recesses have a rectangular cross section.

### Claim 5 (depends on 2)

The anti-climbing device as claimed in claim 2, wherein the recesses have a rectangular cross section.

### Claim 6 (depends on 3)

The anti-climbing device as claimed in claim 3, wherein the recesses have a rectangular cross section.

### Claim 7 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the recesses have a trapezoidal cross section.

### Claim 8 (depends on 2)

The anti-climbing device as claimed in claim 2, wherein the recesses have a trapezoidal cross section.

### Claim 9 (depends on 3)

The anti-climbing device as claimed in claim 3, wherein the recesses have a trapezoidal cross section.

### Claim 10 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the baffle plate is connected to the first and second formations in a non-releasable manner via a welding method.

### Claim 11 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the baffle plate is produced together with the first and second formations in an integral manner via a milling method.

### Claim 12 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the baffle plate is produced together with the first and second formations in an integral manner via a forging method.

### Claim 13 (depends on 1)

The anti-climbing device as claimed in claim 1, wherein the baffle plate is produced together with the formations in an integral manner via a casting method.

### Claim 14

An anti-climbing device for a rail vehicle comprising:
a baffle plate;
a plurality of mutually parallel protruding first formations arranged along a linear path on the baffle plate;
a plurality of mutually parallel protruding second formations arranged on the baffle plate along another linear path and orientated normally with respect to the first formations;
wherein an extent of the second formations over a face of the baffle plate is smaller than an extent of the first formations over the face of the baffle plate;
wherein at intersection locations of the first and second formations the first formations each have a recess in which the extent of the first formations is reduced; and
wherein the extent of the first formation in a region of the recesses is reduced to the extent of the second formations.
