Rail Securing System

Abstract

The invention relates to a system (1) for securing a rail (2) by pinching the rail, comprising: a spring (3) bearing on the rail base (2a), a means (5) for securing the spring to a structure (4) carrying the rail, characterized in that the spring means bears against a device (6) for adjusting the spring comprising: a means (7) for supporting the spring, intended to be in contact with an edge of the rail, the spring being unable to move in translation with the support means, a means (8) for anchoring to the structure supporting the rail, a means (9) for adjusting the position of the support means with respect to the anchoring means.

1 . A system for securing a rail by pinching the upper face of the base of the rail and by laterally blocking the rail, comprising:
 a spring means capable of coming into abutment on the upper face of the base of the rail;   a means for securing the spring means to a support structure of the rail,   
       wherein the spring means come into abutment on a device for adjusting the spring means comprising:
 a means for supporting the spring means intended to be in contact with a lateral edge of the base of the rail, the spring means being mounted on the support means ( 7 ) and being translationally secured with the means for supporting the spring means; 
 a means for anchoring to the support structure of the rail; 
 a means for adjusting the position of the support means relative to the anchoring means. 
 
     
     
         2 . The rail securing system as claimed in  claim 1 , wherein the securing means is mounted passing through at least the means for supporting the spring means and/or the anchoring means. 
     
     
         3 . The rail securing system as claimed in  claim 1 , wherein the spring means comprises at least:
 a first part providing an interface for interacting with the securing means, so that the spring means is kept in abutment on the support means by the securing means;   a second part comprising a portion intended to interact with an upper face of the base of the rail, so that the interaction of the securing means on the spring means in no way or only marginally affects the deformation of the second part.   
     
     
         4 . The rail securing system as claimed in  claim 1 , wherein the anchoring means comprises at least one element projecting on the lower face thereof, intended to be in contact with the surface of the support structure of the rail. 
     
     
         5 . The rail securing system as claimed in  claim 1 , wherein the support means comprises at least one interface forming a stop for interacting with at least one portion of the spring means and moving said means in a substantially horizontal plane. 
     
     
         6 . The rail securing system as claimed in  claim 1 , wherein the support means is mounted, directly or indirectly, in abutment on an upper face of the anchoring means. 
     
     
         7 . The rail securing system as claimed in  claim 6 , wherein the means for supporting the spring means is slidably mounted on the anchoring means in a substantially horizontal plane and along an axis perpendicular to the edge of the system intended to be in contact with the rail, i.e. the edge of the support means intended to be in abutment against the base of the rail. 
     
     
         8 . The rail securing system as claimed in  claim 1 , wherein the adjustment means comprises at least one interface forming a stop blocking the movement, in a substantially horizontal plane, of a first element of a list comprising the support means and the anchoring means. 
     
     
         9 . The rail securing system as claimed in  claim 8 , wherein the adjustment means comprises an interface for engaging with the second element of the list comprising the support means and the anchoring means. 
     
     
         10 . The rail securing system as claimed in  claim 9 , wherein the engagement interface is produced by at least one ramp intended to engage with a matching surface supported by the second element of the list comprising the support means and the anchoring means. 
     
     
         11 . The rail securing system as claimed in  claim 10 , wherein the ramp of the engagement interface uses a flat surface supporting at least one guide rail oriented in a direction forming a non-zero and non-perpendicular angle with an axis perpendicular to the edge of the support means intended to be in contact with a lateral edge of the base of the rail. 
     
     
         12 . The rail securing system as claimed in  claim 9 , wherein the engagement interface is produced by at least one thread oriented in a direction forming a non-zero and non-perpendicular angle with an axis perpendicular to the edge of the system intended to be in contact with the rail. 
     
     
         13 . A method for implementing the rail securing system as claimed in  claim 1 , wherein the method comprises at least:
 a step of pressurizing the anchoring means with the means for supporting the spring means by the means for securing the spring means;   a step of moving the adjustment means, which, by means of an engagement interface, causes the means for supporting the spring means to slide relative to the anchoring means.
