Definitions

• the invention relates to a device for resiliently supporting movable switch parts of a rail switch, with a spring-mounted sliding part or at least one spring-mounted roller, by means of which the movable switch part is lifted off an associated sliding chair, the spring-loaded mounting of at least one leg of a U -shaped bracket is formed.
• a device of the type mentioned has become known, which comprises a resilient sliding device.
• a U-shaped spring element with one leg is rigidly connected to a base, whereas the free leg of the U-shaped spring element carries a sliding part.
• the spring force of the spring element is overcome and the switch tongue rests on the associated sliding chair.
• the spring element lifts the switch tongue from the sliding chair, so that only the frictional forces remaining between the sliding part and the tongue have to be overcome during the changeover process.
• the device according to the invention consists essentially in that the U-shaped bracket is rigidly connected at the free end of a leg facing away from the sliding part to the rail foot of an immovable switch part or the web of a movable switch part and that both legs of the U-shaped Brackets are pivotally arranged relative to the rail foot or the web of a movable switch part.
• both legs of the U-shaped bracket are pivotable relative to the rail foot of an immovable switch part or the web of a movable switch part, both legs of the U-shaped bracket are available to exert the necessary spring force, so that overall a lighter design can be selected to achieve the required travel and spring force.
• the attachment of the U-shaped bracket to the free end of a leg facing away from the sliding part allows a particularly simple fixing using a particularly small number of components and a simple clamp connection can be provided here. Since both free legs can be pivoted with respect to the articulation parts on which the U-shaped bracket is rigidly fixed, such a design allows subsequent adjustment and in particular a pre-adjustment of the pivot position to be achieved with particularly simple means.
• the design according to the invention is such that the U-shaped bracket has at least one carries the extension around the rail foot.
• Such an extension which is formed directly on the U-shaped bracket and overlaps a rail foot, allows the entire spring element to be simply plugged onto the foot of a rail, so that a particularly simple fixing is achieved.
• the required holding force when connecting to a rail foot can be ensured in a particularly simple manner in that the extension encompassing the rail foot is resilient.
• a particularly simple adjustment of the swivel position and thus adjustment of the device according to the invention succeeds if, as is a preferred development, the design is such that the extension encompassing the rail foot or the end of the bracket connected to the web of the movable switch part is cranked over one trained section of the spring clip is connected by means of a clamping device.
• both the extension encompassing the rail foot and the cranked section can be made in one piece from the material of the spring clip, with a particularly simple tensioning device being designed in the form of a hook-shaped mounting bracket, which in the area of the cranked section with the U-shaped stirrup connected behind the stiffening plate.
• the stiffening plate follows the contour of the U-bracket and contains, for example, a rectangular recess in order to enable screwing from above. This significantly increases the spring stiffness of the U-bracket in the clamping area without having to make dimensional changes to the bracket itself.
• a sliding part not only a sliding part but also a roller can be fixed to a free leg of the U-shaped bracket.
• the design is advantageously made such that the free leg of the bracket carrying the sliding element is slotted in the longitudinal direction of the leg and that at least one support roller in the longitudinal direction of the leg in the slot is slidably mounted and fixable in its displacement position.
• the corresponding mounting for a roller can be created without additional components in that only one slot is provided in one of the legs of the U-shaped bracket, which, to make matters worse, can be displaced in a particularly simple manner in the longitudinal direction of the leg and its displacement position fixable can be stored.
• the design is such that the support roller (s) can be (are) displaced in the longitudinal direction of the leg via a spindle which is supported in the region of the curvature of the U-shaped bracket, in particular in a resilient manner, here again in particular a simple one-piece design from the material of the U-bracket is possible by simply bending correspondingly punched or cut sections.
• the design is such that the extension overlapping the rail foot and possibly the support part for the spindle are bent in one piece from the material of the U-shaped bracket.
• a particularly simple design of the displaceable bearings for a support roller which can be displaced in the longitudinal direction of a leg of the U-shaped bracket can be achieved in that the displaceable bearings of the support rollers grip around the edges of the slot in a claw-like manner, and in particular are formed by a bearing axis having diametrical grooves at their ends are.
• a compact unit which consists of a single specially shaped resilient holding element exists, which can be attached to the base of a stock rail in a particularly simple manner and at the same time serves as a carrier element for sliding elements or rolling elements.
• both the lower and the upper leg of the U-shaped spring element are used as a spring element, the shape of the base body making it possible to do without additional holding elements.
• stops can be provided on this component on one side and resilient counter brackets in the form of an overlapping extension on the other side, so that the entire device can be fixed directly on the foot of a stock rail without tools.
• the tensioning device or the spindle for moving support rollers can be used to adjust the sliding or rolling elements in the horizontal and vertical directions, so that a particularly simple and reliable and widely adjustable resilient sliding or roller bearing is available for switch tongues ,

• a U-shaped spring element 5 is fixed, the fixing being carried out by a resilient extension 6 overlapping the rail foot 4 and a stop 7 of the U-shaped bracket 5.
• the U-shaped bracket 5 thus has a lower leg 8 and an upper leg 9 which is substantially parallel to this leg, both of which leg act as a spring element, since there is no further support in the area of the legs 8 and 9.
• a sliding element 10 is fixed, the spring force being such that the tongue 2 is lifted off the sliding chair 3 during the changeover process.
• the correct positioning of the spring clip 5 and in particular the pivot position of the two legs 8 and 9 can be adjusted by a tensioning device 11 which is supported on a cranked section 12 of the U-shaped clip 5 and consists of a nut cooperating with a screw bolt 13 ,
