A mobile rack having at least four caster wheels and at least one device according to claim 1 for simultaneously acting on at least two of the caster wheels so as to brake the at least two of the caster wheels, wherein the two levers are disposed for rotation in a plane parallel to the plane of a running support of the caster wheel. 8. The rack according to claim 7, wherein the at least two of the caster wheels are not arranged diagonal to each other at the mobile appliance. 9. The rack according to claim 7, wherein the at least two of the caster wheels are arranged adjacent to each other at the mobile appliance. 10. The device according to claim 1, including at least one means for exerting thrust on at least one of the levers so as to cause the at least one of the levers to rotate about its fulcrum. 11. The device according to claim 10, wherein the at least one means for exerting thrust has the form of a push rod or a push member. 12. The device according to claim 1, wherein at least one lever is rotatable about exactly one fulcrum, respectively. 13. The device according to claim 12, wherein all of the levers are rotatable about exactly one fulcrum, respectively. 14. The device according to claim 1, wherein the at least four transmission means for transmitting the generated tensile force and/or pressing force to the four brake means includes at least one compression spring. 15. The device according to claim 1, wherein the fulcrum is a fixed fulcrum.
