A mounting element for the wheels of rolling containers comprises: a load-bearing member rigidly attachable to a bottom edge of a container designed to be rolled along a surface; an arm supporting at least one wheel designed to enable the container to be rolled on the surface; a pivot connecting the load-bearing member to the arm; and a helical spring located between load-bearing member and the arm. The latter, together with the load-bearing member defines a substantially sealed chamber within which the spring is enclosed and protected, and presents three end portions located at respective vertices of a triangle, a first portion being rotatably attached to the pivot, a second portion rotatably supporting the wheel and a third portion being attached to the spring.

1. A mounting element for the wheels of rolling containers comprising: a load-bearing member rigidly attachable to a bottom edge of a container designed to be rolled along a surface; an arm supporting at least one wheel designed to enable the container to be rolled on the surface; a pivot connecting the load-bearing member to the arm; and means for absorbing mechanical energy located between the load-bearing member and the arm; the arm presenting a first portion that is rotatably attached to the pivot, a second portion that rotatably supports the wheel, and a third portion coupled with the mechanical energy absorbing means; wherein the load-bearing member and the arm define a substantially sealed chamber within which the mechanical energy absorbing means are enclosed and protected at each of the positions of the load-bearing member and of the arm. 2. The mounting element according to claim 1, wherein the first, second and third portions are three end portions of the arm located at respective vertices of a triangle. 3. The mounting element according to claim 2, wherein the distance between the first and second portions is smaller than the distance between the first and third portions. 4. The mounting element according to claim 1, wherein the mechanical energy absorbing means are elastic means; the arm being designed to rotate about the pivot from a first to a second position against the opposing action of the elastic means. 5. The mounting element according to claim 4, wherein the elastic means comprise a helical spring. 6. The mounting element according to claim 1, wherein the arm has a prismatic shape with a substantially triangular longitudinal section. 7. The mounting element according to claim 1, wherein the load-bearing member defines a housing having a cavity within it; the arm being housed at least partly inside the housing. 8. The mounting element according to claim 7, wherein the cavity has a prismatic shape with a substantially trapezoidal longitudinal section. 9. The mounting element according to claim 7, wherein the housing has a slot through which the arm can slide while providing a substantial seal. 10. The mounting element according to claim 7, wherein the cavity, together with the arm, defines the chamber, and has an opening consisting of a slot through which the arm can slide relative to the load-bearing member; the arm substantially sealing the opening at all its positions relative to the load-bearing member. 11. The mounting element according to claim 1, wherein, when the container is being pulled in the direction, the first portion is positioned behind the second and third portions. 12. A rolling container comprising at least one mounting element according to claim 1. 13. The mounting element according to claim 2, wherein the mechanical energy absorbing means are elastic means; the arm being designed to rotate about the pivot from a first to a second position against the opposing action of the elastic means. 14. The mounting element according to claim 3, wherein the mechanical energy absorbing means are elastic means; the arm being designed to rotate about the pivot from a first to a second position against the opposing action of the elastic means. 15. The mounting element according to claim 2, wherein the arm has a prismatic shape with a substantially triangular longitudinal section. 16. The mounting element according to claim 2, wherein the load-bearing member defines a housing having a cavity within it; the arm being housed at least partly inside the housing. 17. The mounting element according to claim 8, wherein the housing has a slot through which the arm can slide while providing a substantial seal. 18. The mounting element according to claim 9, wherein the cavity, together with the arm, defines the chamber, and has an opening consisting of a slot through which the arm can slide relative to the load-bearing member; the arm substantially sealing the opening at all its positions relative to the load-be aring member. 19. The mounting element according to claim 2, wherein, when the container is being pulled in the direction, the first portion is positioned behind the second and third portions. 20. A rolling container comprising at least one mounting element according to claim 2. 21. A mounting element for the wheels of rolling containers comprising: a load-bearing member rigidly attachable to a bottom edge of a container designed to be rolled along a surface; an arm supporting at least one wheel designed to enable the container to be rolled on the surface; a pivot connecting the load-bearing member to the arm; and means for absorbing mechanical energy located between the load-bearing member and the arm; the arm presenting a first portion that is rotatably attached to the pivot, a second portion that rotatably supports the wheel, and a third portion coupled with the mechanical energy absorbing means; wherein the load-bearing member defines a housing having a cavity within it; the arm being housed at least partly inside the housing; the cavity, together with the arm, defining a substantially sealed chamber and having an opening consisting of a slot through which the arm can slide relative to the load-bearing member; the arm substantially sealing the opening at all its positions relative to the load-bearing member; the mechanical energy absorbing means being enclosed and protected inside the substantially sealed chamber at each of the positions of the load-bearing member and of the arm.
