Abstract

A fastening system for fastening a rail for rolling stocks such as trains, including a base plate, an elastic material and a rigid casing, wherein the base plate is embedded in the elastic material and the elastic material is arranged, at least partially, between the base plate and the rigid casing.

First claim

The invention claimed is:

1. A fastening system for fastening a rail for rolling stocks, comprising
a base plate,
an elastic material comprising at least two zones including a first zone that is at or closer to an inner side of the fastening system, and a second zone that is at or closer to an outer side of the fastening system, the first zone having a lower e-modulus than the second zone, and
a rigid casing,
wherein:
the base plate is embedded in the elastic material, and
the elastic material is arranged, at least partially, between the base plate and the rigid casing.

2. The fastening system of claim 1 , wherein the rigid casing comprises at least one of: a rigid bottom surface, a first rigid frame part encasing a first edge portion of the base plate, and a second frame part encasing a second edge portion of the base plate.

3. The fastening system of claim 1 , wherein the elastic material comprises at least one of: an elastic bottom surface, a first elastic frame part encasing a first edge portion of the base plate, and a second elastic frame part encasing a second edge portion of the base plate.

4. The fastening system of claim 1 , wherein the elastic material covers at least one of: a lower surface of the base plate, one or two longitudinal edges of the base plate, one or more portions of one or two transversal edges of the base plate, and one or two portions of an upper surface of the base plate.

5. The fastening system of claim 1 , wherein the rigid casing covers at least one of: a lower surface of the base plate, one or two longitudinal edges of the base plate, one or more portions of one or two transversal edges of the base plate, and one or two portions of an upper surface of the base plate.

6. The fastening system of claim 1 , wherein the rigid casing covers at least one of: a lower surface of the elastic material, one or two longitudinal edges of the elastic material, one or more portions of one or two transversal edges of the elastic material, and one or two portions of an upper surface of the elastic material.

7. A fastening and support system for fastening and supporting a rail for rolling stocks, comprising the fastening system of claim 1 and a support structure.

8. The fastening and support system of claim 7 , wherein the rigid casing is glued onto a surface of the support structure and/or the rigid casing is embedded in the support structure.

9. The fastening and support system of claim 7 , wherein the fastening system is fixed to the support structure via at least one anchoring device.

10. A method of producing the fastening and support system according to claim 7 , the method comprising:
embedding the base plate in the elastic material and arranging the elastic material, at least partially, between the base plate and the rigid casing, and
connecting the fastening system to the support structure.

11. A method of producing a rail system comprising:
performing the method according to claim 10 , and
arranging at least one rail on the fastening system.

12. A method for fastening and supporting a rail for rolling stocks, the method comprising:
fastening and supporting the rail for rolling stocks with the fastening and support system according to claim 7 .

13. A rail system comprising
the fastening system according to claim 1 , and
at least one rail.

14. The rail system according to claim 13 , wherein the rail system comprises the support structure.

15. A method of producing the fastening system according to claim 1 , the method comprising:
embedding the base plate in the elastic material and arranging the elastic material, at least partially, between the base plate and the rigid casing.

16. A method for fastening a rail for rolling stocks, the method comprising:
fastening the rail for rolling stocks with the fastening system of claim 1 .
