Patent ID: 8052067

Claim:
A self-cleaning assembly for one of a ground-level guide-rail ( 2 ) or rolling rail ( 1 ) carrying one of rollers or wheels with flanges ( 15 ) of a terrestrial vehicle, the rail being fitted into a recess ( 4 ) formed in a solid base ( 5 ), and being mounted and held in the recess ( 4 ) one of flush with the ground or only slightly protruding above ground level and having gaps ( 12 ) on at least one side of the rail that corresponds to the passage of the flanges, wherein a lining material ( 14 ) is arranged in the gaps ( 12 ) outside a dynamic engagement area of the flanges and at least partially lines the gaps, at least partially filling the gaps, the lining material ( 14 ) having compressibility properties and being arranged so that under all normal conditions of use or environmental conditions, the lining material ( 14 ) maintains the filling of the gaps outside the dynamic engagement area of the flanges ( 15 ) of the rollers or wheels moving along the rail; and a lining ( 13 ) formed of the lining material ( 14 ) opens in a V-shape toward a top and grips the rail ( 2 ) at least in a middle area, delimiting on either side of the rail ( 2 ), in each case, an area ( 29 , 30 ) that slopes down toward the rail followed by a longitudinal groove ( 31 , 32 ).
