## Abstract

An elastic clip for fixing a railway rail, comprising a head arch having a front end thereof inserted into a clip shoulder of a base plate or a tie; a first front arch extending in one piece from the head arch and upwardly curved in an oblique direction; a first toe extending in one piece from the first front arch and having a bottom thereof contacting a top of a flange of a rail; a second front arch extending in one piece from the first toe and upwardly curved in an oblique direction; and a second toe extending in one piece from the second front arch and having a top of a front end of thereof contacting a bottom of the head arch.

## Claims

### Claim 1

An elastic clip for fixing a railway rail, comprising:
ahead arch having a front end to be inserted into a clip shoulder of a base plate or a tie;
a first arch extending in one piece from the head arch and upwardly curved in an oblique direction;
a first toe extending in one piece from the first front arch and disposed in a downward direction of the first arch and having a bottom surface to be contacted on a top surface of a flange of a rail;
a second arch extending in one piece from the first toe and upwardly curved in an oblique direction; and
a second toe extending in one piece from the second arch and disposed in a downward direction of the second arch and having a front end,
wherein the front end of the second toe is disposed under the head arch, and a top surface of the front end of the second toe contacts a bottom surface of the head arch.

### Claim 2 (depends on 1)

The elastic clip of claim 1, wherein the elastic clip is configured such that the top surface of the front end of the second toe is spaced from the bottom surface of the head arch by about 0.2 mm to about 2.0 mm when the elastic clip is installed in the clip shoulder, and the top surface of the front end of the second toe contacts the bottom surface of the head arch when the rail is lifted in a state where the elastic clip is installed in the clip shoulder.

### Claim 3

An elastic clip for fixing a railway rail, comprising:
a head arch having a front end to be inserted into a clip shoulder of a base plate or a tie;
a first arch extending in one piece from one end of the head arch and upwardly curved in an oblique direction;
a first toe extending in one piece from the first arch and disposed in a downward direction of the first arch and having a bottom surface to be contacted on a top surface of a flange of a rail;
a second arch extending in one piece from the first toe and upwardly curved in an oblique direction;
a second toe extending in one piece from the second arch and disposed in a downward direction of the second arch and having a front end;
a head arch front end extension extending in one piece from the other end of the head arch by a certain length in a straight line; and
a third toe extending in one piece from the head arch front end extension and having a front end upwardly curved in an oblique direction,
wherein the front end of the second toe is disposed under the head arch, and a top surface of the front end of the second toe contacts a bottom surface of the head arch.

### Claim 4 (depends on 3)

The elastic clip of claim 3, wherein the third toe extends from the head arch by a length of about 2 mm to about 15 mm.

### Claim 5 (depends on 3)

The elastic clip of claim 3, wherein a top surface of a front end of the third toe higher than a top surface of the head arch front end extension by a length of about 0.5 to about 3.0 mm.

### Claim 6 (depends on 4)

The elastic clip of claim 4, wherein a top surface of a front end of the third toe higher than a top surface of the head arch front end extension by a length of about 0.5 to about 3.0 mm.
