Wall element for an animal cage

1. An animal cage comprising:

four extruded profiles on a cage wall which form a rectangle and include a horizontal extruded profile and an upright extruded profile;

a longitudinal groove on each of the tour extruded profiles;

and

a wall element for improving crash safety, which is rectangular, is fitted between the four extruded profiles and comprises side edges and at least one elastically compressible cavity configured to increase a crash safety of the animal cage,

wherein:

a) each of the side edges of the wall element forms a tongue of a tongue-and-groove connection with the longitudinal groove of a corresponding one of the four extruded profiles;

b) a metal insert is arranged at an end of the horizontal extruded profile for connection to the upright extruded profile;

c) the metal insert has three tines which project substantially parallel to one another from the metal insert;

d) a central tine of the three tines engages axially in a cavity of the horizontal extruded profile;

e) two outer tines of the three tines engage axially in two opposite longitudinal grooves of the horizontal extruded profile; and

f) the metal insert is connected to the upright extruded profile adjacent thereto.

2. The animal cage according to claim 1 , wherein the wall element is manufactured by blow molding.

3. The animal cage according to claim 1 , wherein the wall element further comprise

a) a convexly curved inner surface facing an interior of the animal cage when assembled; and

b) an exterior surface facing away from the interior of the animal cage when assembled, the exterior surface being substantially flat or concave or at least less convex than the interior.

4. The animal cage according to claim 1 , wherein the wall element comprises plastic.

5. The animal cage according to claim 4 , wherein the plastic comprises a material selected from the group consisting of polyethylene and acrylonitrile-butadiene-styrene.

6. The animal cage according to claim 4 , wherein the plastic comprises high-density polyethylene.

7. The animal cage according to claim 1 , wherein the at least one elastically compressible cavity has a volume of at least 50 cm 3 .

8. The animal cage according to claim 1 , wherein the wall element has several ribs which each form the at least one elastically compressible cavity.

9. The animal cage according to claim 8 , wherein the ribs run parallel to each other.

10. The animal cage according to claim 9 , wherein the ribs are arranged substantially equidistantly.

11. The animal cage according to claim 10 , wherein the ribs run upright in an assembled state.

12. The animal cage according to claim 11 , wherein a number of ribs is greater than 3.

13. The animal cage according to claim 12 , wherein the number of ribs is less than 10.

14. The animal cage according to claim 1 , wherein the metal insert is at least partially surrounded by a plastic sheath which prevents direct contact between the metal insert and the horizontal extruded profile.

15. The animal cage according to claim 1 , wherein

a) the animal cage has a cage door on one side, and

b) the wall element serving to improve crash safety is arranged opposite the cage door.

16. The animal cage according to claim 1 , wherein the extruded profiles are made of aluminum or an aluminum alloy.

17. The animal cage in accordance with claim 1 , wherein the animal cage complies with at least one of technical standards ECE R17, ECE R126 and DIN75410 for crash safety and load securing.

18. The animal cage according to claim 1 , wherein the wall element serving to improve crash safety is curved inwards.
