Abstract
The invention relates to a device (1) which is used to lift and displace the tongue blade (2) of a rail (6), comprising at least two rollers (12, 14) whereby the axes thereof are arranged in an essentially parallel manner in relation to a running rail (4), in order to displace the tongue blade (2) in a transversal manner in relation to the running rail (4), at least two support carrier pins (22, 24) which respectively support a roller (12, 14), and a base body (8) which supports the carrier pins (22, 24). The rollers (12, 14) have a projection which projects in at least one first direction in relation to the base body (8). The inventive device is characterised in that a covering (10) is arranged between at least two adjacent rollers and is oriented towards the first direction and at least partially covers a passage between the at least two adjacent rollers (12, 14).
