Definitions

• the invention relates to a rail arrangement
• a rail arrangement comprising a first rail arranged on a support plate, such as a stock rail with a rail foot, and a second rail arranged on a (second) plate, such as a sliding chair, such as a switch tongue with a rail foot, which is fixed between projections such as ribs and via fastenings such as tension clamps is held down on the plate, the second plate being clamped to the base plate via at least one spring element and holding down the rail foot of the first rail or at least forming a tilt protection for the latter.
• a device which consists of a sliding chair arranged separately from the base plate, which forms a positive connection with the foot of the stock rail and is braced on the base plate by a spring element lying on the side of the sliding chair.
• the spring element has a U-shape and is supported with its free leg ends on a support lying above the base of the stock rail. If the U-shaped spring element breaks, the sliding chair can no longer hold down the stock rail.
• EP 0 336 311 B1 describes a device for fastening a rail, the foot of which is held down by a spring element which starts from a sliding chair which is detachably arranged on the base plate and is tensioned via an abutment which is an integral part of the base plate.
• a two-part sliding chair is known from EP 0 113 515 AI.
• a first part of a sliding chair which is supported with a section on the foot of the rail, releasably starts from a second part which is firmly connected to a base plate.
• a stock rail fastening can be found in EP 0 343 149 A2, in which a spring with a progressive characteristic curve is supported on the broach rail foot.
• an elastic intermediate layer is arranged between a sliding chair, which is supported on a cheek rail foot, and a base.
• the present invention has for its object, among other things, to further develop a device of the type described above so that, on the one hand, a tilting of the rail is precluded with a simple structural design and, on the other hand, it is ensured that the second plate even if the spring or springs holding it down breaks cannot be moved to the base plate in an uncontrolled manner, so that a safe holding down of the rail, such as stock rail, is always guaranteed. It is also an object of the invention to be able to fix the second rail like switch tongue in desired positions on the second plate or to be able to easily adapt to different rail foot widths.
• the object is essentially achieved in that the plate is connected to the base plate via a connecting element such as a screw element, which preferably interacts with one of the fastenings for the rail foot of the second rail.
• the fastening element on the rail base of the second rail can also be used to screw the second plate - in addition to the basically existing securing element via at least one spring element - onto the base plate in order to provide additional securing means.
• the screw element penetrates at least one of the projections like a rib.
• a further development of the invention provides that the screw element passes through a slot which runs in the longitudinal direction of both the plate and the base plate.
• the projections such as ribs to rails with different rail foot widths without the second plate having to be replaced
• a further proposal of the invention provides that at least one of the projections with the respective screw element is arranged displaceably in the slot.
• both projections can be moved like ribs with the screw elements and screwed into the desired positions.
• the slot has an insertion opening suitable for the displaceably arranged screw element, in particular from the end facing away from the rail the slot runs out.
• the slot is limited by projections extending at least in certain areas into the second plate and extending from the base plate, such as L-shaped cheeks or legs in section. These projections extend in the longitudinal direction of the base plate or plate, so that it is additionally secured against rotation.
• the projections such as ribs can optionally be arranged displaceably to the second plate, it is preferably provided, however, that at least one of the fastenings for the rail foot of the second rail is an integral part of the plate.
• An independent proposed solution of the invention is characterized in that the projections, like ribs, originate from a third plate which is detachably connected to the second plate via at least one of the screw elements cooperating with one of the fasteners.
• the third plate can be slidably arranged in relation to the second plate in order to be able to adjust the projections to the desired distance of the rail from one another.
• the screw element penetrates both the base plate and the second plate, so that the plate that additionally serves as a hold-down or tilt protection for the rail foot of the second rail is secured.
• the projections such as ribs themselves are preferably integral components of the third plate.
• the projections can itself be displaced in the longitudinal direction of the third plate.
• FIG. 2 shows a section of the rail arrangement according to FIG. 1, partially cut
• Fig. 3 is a plan view of the detail of the rail assembly of FIG. 1, but in plan view and partially cut.
• a device for fastening a rail in the form of a stock rail (10) is shown, which is arranged over a rail base (40) on a base plate (12) and on the one hand by a tension clamp ( 14) and on the other hand from a second plate (16) is held down.
• this has a structure of a sliding chair for switch tongues with the restriction that the rail (18) assigned to the stock rail (10) is not displaceable, but is arranged in a fixed position between the ribs (20) and (22) to the stock rail (10).
• the base plate (16) is first detachably connected via rod spring elements (24) and (26) to the base plate (12), which is also referred to as a ribbed plate.
• the rod spring elements (24) and (26) are clamped between abutments (28) extending from the ribbed plate and from the plate (16).
• Support facing away from the rail bear the reference numerals (30) and (32).
• a rail-side support is marked with (34).
• the abutment (28) forms the upper boundary of a channel (36) which is closed on the circumference and open on the end face.
• Each channel (36) has an insertion opening (38) tapering in the direction of the rail (10), the openings (38) running such that each spring element (26) is inserted into the channel (36) from the side and then tensioned between the supports (32) and (34) and the abutments (28).
• the plate (16) with its front section (48) running above the rail foot (40) is pulled onto the rail foot to hold it down.
• the second plate (16) has cavities, so that the former are at least partially surrounded by the second plate (16).
• the rail-side supports (34) extend along the edge along the rail foot (40) of the stock rail (10) which, as it were, bears against a rib (42) on the opposite side and is held down by the tension clamp (14).
• the rod spring elements (24) and (26) further extend in open channels extending from the longitudinal edge, which are delimited on the underside by the ribbed plate (12) and on the upper side by the second plate (16). Each spring element (24) or (26) also projects from the rear of the respective channel in order to be able to easily grasp the rod spring element (24, 26) both for mounting and for removing from the channel.
• An L-shaped projection (44) extends from the center of the ribbed plate (12) and engages in a recess (46) running in the plate (16) and in its longitudinal direction in such a way that if the spring elements (24) and (26 ) lifting the plate (16) is excluded. This results in a further tilt protection for the rail (10).
• the projection (44) can also rest on the edge of the rail foot (40), so that the function of a rib is additionally performed.
• the plate (16) is further secured by a screw (50), by means of which a clamp (52) extending from the rib (22) is tensioned, via which the foot (50 ') of the second rail (18) is held down .
• a corresponding tension clamp is provided on the opposite side, which is provided with the reference symbol (54). The screw that clamps the clamp is screwed to the plate (16).
• the screw (50) passes through a slot (56) which starts from the base plate (12) and ends at the top of the second plate (16).
• the slot (56) is accessible via an insertion opening (58) through which the screw (50) can be inserted.
• the slot (56) is delimited by legs or cheeks of the base plate (12) with an L-shaped section, which are provided with the reference numerals (60) and (62) and - as is illustrated in FIGS. 2 and 3 - in a recess (64) of the plate (16) extend.
• the clear distance between the cross legs (66) and (68) of the legs (60) and (62) is adapted to the diameter of the screw shaft, that is less than the head or nut (70).
• the second plate (16) is additionally secured, so that a further anti-tilt protection for the rail (10) is provided.
• the slotted screw arrangement makes it possible to assign a second base plate (16) to the same base plate such that the ribs (20) and (22) run at different points; because the screw (50) can take any position within the slot (56).
• the slot (56) can optionally have a length which enables both ribs delimiting a rail base to be arranged displaceably.
• an elastic intermediate layer (72) is located between the rail foot (40) of the stock rail (10) and / or the rail foot (50 ') of the switch tongue (10) and the associated base (12) or (16). or (74) runs, on the one hand damping and on the other hand increasing the push-through resistance.
• the teaching of the invention also has the advantage that only two different types of plates are required to hold a switch tongue.
• the plates according to the invention can be longer than usual plates held only by a spring, since additional fastening takes place via the screw. The sudden changes in inertia occurring in known switch areas are avoided.
