Arrangement for holding down a rail

Abstract

The invention relates to an arrangement for holding down a rail ( 14 ) having a rail foot ( 20 ), such as a stock rail, comprising a base ( 18 ), such as a slide chair plate, tongue roller plate or wheel guide plate, a plate element ( 16 ), such as a slide chair or counter bearing, detachably arranged on the base, a spring element ( 10 ) holding the plate element on the base, and a first and a second abutment for tensioning the spring element. To enable the rail to be held down with structurally simple measures and at the same time to achieve ease of maintenance and servicing, it is provided that the first abutment is a section ( 78 ) of the plate element ( 16 ) or extends therefrom, running in the region remote from the rail foot, in that the second abutment is an eccentric element ( 12 ) which preferably extends in the longitudinal direction of the rail ( 14 ) and is arranged rotatably in a receptacle ( 46 ) arranged between the rail foot ( 20 ) and the first abutment and starting from the base ( 18 ), and in that the spring element is designed to be supported on the rail foot ( 20 ).

 wherein the first abutment is a section ( 78 ) of the plate element ( 16 ) or extends therefrom, extending in the region remote from the rail foot, in that the second abutment is an eccentric element ( 12 ), which extends preferably in the longitudinal direction of the rail ( 14 ) and is rotatably arranged in a receptacle ( 56 ) arranged between the rail foot ( 20 ) and the first abutment and extending from the base ( 18 ,  118 ), and in that the spring element is designed to be supported on the rail foot ( 20 ).   
     
     
         2 . The arrangement of  claim 1 , wherein the eccentric element ( 12 ) is a rod-shaped element, such as a shaft, which has an eccentric geometry in cross-section in the contact region ( 70 ) with the spring element ( 10 ) in such a way that the spring element ( 10 ) is untensioned in a first position of the eccentric element and tensioned in a second position in such a way that both the rail foot ( 20 ) and the plate element ( 16 ) are held down. 
     
     
         3 . The arrangement of  claim 1 , wherein the eccentric element ( 12 ) in the contact region ( 70 ) has a geometry of a circular segment or of a circular segmental shape in section. 
     
     
         4 . The arrangement of  claim 1 , wherein the receptacle ( 56 ) has two bearing elements ( 58 ,  60 ) which extend in sections into recesses ( 52 ,  54 ) in the plate element ( 16 ). 
     
     
         5 . The arrangement of  claim 1 , wherein the spring element ( 10 ) extends in the central region of the plate element ( 16 ) and in the longitudinal direction thereof. 
     
     
         6 . The arrangement of  claim 1 , wherein the first abutment ( 78 ) has the geometry of a cylinder section and in that the spring element ( 10 ) rests with a geometrically adapted end region ( 76 ) on the first abutment in such a way that a longitudinal displacement of the spring element in the tensioned state is prevented. 
     
     
         7 . The arrangement of  claim 2 , wherein the cross-sectional region or moment of resistance of the spring element ( 10 ) in the contact region ( 70 ) to the eccentric element ( 12 ) is larger than in the contact region both with the rail foot ( 20 ) and with the first abutment ( 78 ). 
     
     
         8 . The arrangement of  claim 1 , wherein the plate element ( 16 ) for receiving the spring element ( 10 ) has a longitudinal recess ( 44 ) which preferably starts from the first abutment ( 78 ) and extends in the longitudinal direction of the plate element and is bounded by side walls ( 48 ,  50 ), and in that the side walls have the eccentric element ( 12 ) passing through them. 
     
     
         9 . The arrangement of  claim 4 , wherein the bearing elements ( 58 ,  60 ) of the eccentric element ( 12 ) are surrounded in regions by the side walls ( 48 ,  50 ). 
     
     
         10 . The arrangement of  claim 4 , wherein the bearing elements ( 58 ,  60 ) are lateral legs of the receptacle ( 56 ), which has a U-shape in section and the transverse leg ( 72 ) of which extends above the eccentric element ( 12 ). 
     
     
         11 . The arrangement of  claim 1 , wherein the eccentric element ( 12 ) is designed, at least in one of its ends, as an actuating head ( 68 ), such as a polygonal head, in particular a square head, which is located within an outer side of one of the legs ( 48 ,  50 ). 
     
     
         12 . The arrangement of  claim 1 , wherein the plate element ( 16 ) extends, with its end region running on the rail side, above the rail foot ( 20 ) and at a distance therefrom. 
     
     
         13 . The arrangement of  claim 1 , wherein the contact region ( 70 ) between the eccentric element ( 12 ) and the spring element ( 10 ) extends closer to the lower support plane of the base ( 18 ) than the ends (A 1 , A 2 ) of the legs ( 11 ,  13 ) of the spring element facing away from the base with their respective smallest distance from the lower support plane of the base. 
     
     
         14 . An arrangement for holding down a rail ( 14 ) having a rail foot ( 20 ), such as a stock rail, a base ( 18 ,  118 ), such as a slide chair plate, tongue roller plate or wheel guide plate, a plate element ( 16 ), such as a slide chair or counter bearing, extending from the base, a spring element ( 10 ) and a first and a second abutment for tensioning the spring element, the first abutment being a section ( 78 ) of the plate element ( 16 ) or extending therefrom, which extends in the region remote from the rail foot, and the second abutment is an eccentric element ( 12 ) which preferably extends in the longitudinal direction of the rail ( 14 ) and is rotatably arranged in a receptacle ( 46 ) located between the rail foot ( 20 ) and the first abutment, the spring element being designed to be supported on the rail foot ( 20 ). 
     
     
         15 . The arrangement of  claim 14 , wherein the eccentric element ( 12 ) is a rod-shaped element, such as a shaft, which has an eccentric geometry in cross-section in the contact region ( 70 ) with the spring element ( 10 ) in such a way that the spring element ( 10 ) is untensioned in a first position of the eccentric element and tensioned in a second position in such a way that both the rail foot ( 20 ) and the plate element ( 16 ) are held down.
