Abrégé

The invention relates to a device for moving a tongue rail (2) of a gate, having a retaining element (7) attached to a stock rail (3) and at least one roller (1) fastened thereto, the rotation axis of which is substantially parallel to the course of the rail, and which is arranged such that the tongue rail (2) can roll on the roller (1) from a lower resting position on the stock rail (3) to a distant position, and having a spring element (13). A simplified configuration of the device can be achieved in that the spring element (13) is arranged in the interior of the roller (1) and that the roller (1) is fastened by at least one screw connection and is adjustably fixed in a slide rail (7a) on the retaining element (7).

The invention relates to a switch for railway systems, with a frog (1), the point (1a) of which is movable between a first position bearing against a first wing rail (2) and a second position bearing against a second wing rail (3), with a supporting surface (4) for supporting the frog point (1a), wherein the frog point (1a) rests on a strap (5) which is mounted outside the first and the second wing rail (2, 3) on a respective roller (9a, 9b) in order to lift the frog point (1a) during the movement between the first position and the second position, wherein the rollers (9a, 9b) each roll along a running track (11a, 11b), and at least one running track (11a, 11b) has lowered end sections (12a, 13a; 12b, 13b). A solution which can advantageously be retrofitted is provided by the frog point (1a) engaging under the first and the second wing rail (2, 3) and by the strap (5) having a base (6) which, in the central region thereof, has a receptacle (8) for the frog (1) and which is lowered in relation to laterally adjoining supporting sections (7a, 7b).
