Description

The invention relates to a rail fastening Device according to the preamble of claim 1.

Such a device is from GB 2 085 057 A knows. It consists essentially of two parts, näm Lich a holding or anchoring device and one essentially helical in plan view nem spring clip, one end of which is in a straight line Anchoring section opens into an opening in the Anchoring device is inserted. The other free end of the spring clip opens into a support cut, the underside of which is flattened and at mon spring clip on the top of a rail foot (or the top of one that covers the rail foot Insulation angle) and this never by spring force holds. The holding device points to that of the rail an abutment on the opposite side of the opening, on the one opposite the support section Abutment section of the spring clip rests. The feather clip has three support sections, namely

• 1. the support section, which on the rail foot or an insulation bracket rests;
• 2. the opposite abutment section, the rests on the abutment; and
• 3. the rectilinear anchoring section, which on the Top of the anchoring opening is present.

This rail fastener, which has been tried and tested in practice However, the delivery device leaves several wishes unfulfilled:

For one thing, it is desirable to have an "overload protection" provide to prevent the rail from being on it transverse or vertical forces acting on a front given dimension tilted or ver by wheel loads is bent or even tips over.

Furthermore, to neutralize the track of the spring clip can be relaxed, which can be done by the fact that the Spring clip is pushed away from the rail so that it is released from the abutment and the support section of the rail foot or one that covers the rail foot Insulation bracket releases. Then must with a lever tool or a hammer the clip back into the clamping position to be brought.

Finally, it is desirable to make the spring clip better against slow slipping out of the anchor device to secure what in the known spring clip of this type due to the longitudinal walkway that arises during operation can move the rail.

The object of the invention is therefore the known shooting to improve nenbefestigungsvorrichtung in that Overload protection rea with little technical effort is identified.

This task is carried out in the characterizing part of the Features specified 1 solved. Advantage strong designs and further training are the sub claims.

Furthermore, it should be possible with little additional  Effort also the functions "neutralization position" and / or Realize "protection against slipping out".

The overload protection is described by in claim 1 Level design of the spring clip realized by the stopper section which is in the normal operating position lung (clamping position) unhindered by the support section protrudes and presses against a stop in the event of an overload. This makes an additional, very hard one in the event of an overload Spring effective, a further lifting of the support ab cut prevents. In a variant of the invention this stop section also serves the Function of the neutralization position, namely by a Raising the stop section also raising the Support section and thus a relief of the shooting effect. Finally, this stop serves also cut the fuse against this variant Slip out by this stop section at Ver push the spring clip in the longitudinal direction of the rail hits a stop and thus another ver slide in the longitudinal direction of the rail. By the features of claim 1 thus becomes an overload Protection implemented with a progressive characteristic.

With the features of claim 2, this is progressive Spring characteristic curve from the onset of the overload protection designed particularly steep.

With claims 3 and 4 are two different Realized variants in which the function of the over load protection solely through the design of the spring clip is reached and ver conventional anchoring parts can be applied. In the variant of claim 5 the effective spring length for overload protection is wider shortened so that there is a steeper progressive spring characteristic results. That is, however, the anchor to modify the facility. With claims 6, 7 and  8 is the for the three different variants The stop surface for the overload protection is enlarged to the Material stress due to excessive surface pressure reduce.

With claim 9 is achieved in all three variants, that in the normal operating position always the full one Spring force of the spring clip presses on the rail foot and not through the stop section in any way is reduced.

With claim 10 in the first two variants Function of the "neutralization position" reached. Will the Spring clip in the longitudinal direction of the rail only by one be If the correct route is moved, it will be opened of the anchoring part inserted anchoring section can spring up a little, which makes the spring clip is relieved and the support section with less Force or no more on the rail foot presses. So that must neutralize the rail Spring clip not completely out of the anchoring part removed as was previously required. To after to neutralize the spring clip again tension, it is sufficient to completely insert it back into the Insert anchoring part, for example by a Lever tool or hammer blows.

With claim 11 is the interaction of the slope with the stop section the function "neutralize position ".

With claim 12 one achieves with all three variants a safeguard against slipping out. This backup can can also be provided for two positions of the spring clip, namely the normal operating position and the neutral position.  

Another protection against slipping out is obtained also by the features of claims 13 and 14.

Claim 15 shows a similar protection against out slide that is specifically for the second variant of the infin is tailored.

Claim 16 realized in cooperation with the attack section with a special design of Ver anchoring part securing against slipping out.

With claim 17 is a particularly favorable form of Anchoring part suggested that in a simple manner the three functions overload protection, neutral position and protection against slipping out in cooperation with the stop section realized.

Claim 18 provides a clearly defined force or Stress distribution along the spring clip reached, since in the normal operating position all three editions points lie along a line of action.

All three embodiments of the invention are ge together that the overload protection is achieved by that the helical curved spring clip one to the Short contact area on the rail foot Has leg that points away from the rail foot and - depending on the embodiment - in different places  len the spring clip or the anchor to the stop comes when a given travel has been completed. As soon as this stop, which at all previous Aus tours are not available, so that so far spring free end without a stop occurs without Overuse of the clip as well as the anchoring much higher tension force in function.

The spring clip thus has a kinked spring characteristic, in the normal work area until the onset of Overload protection runs with a predetermined slope and with the onset of the overload protection with a second, very steep slope. At the first and second embodiment can be a conventional holding or Anchoring device used without modification become; it only needs a new spring clip after the Invention are used. The first and second out You will be given a leadership example with use unchangeable anchorages while the third embodiment for the new installation of the Anchoring is used. The third execution For example, the holding or anchoring must be direction to be modified somewhat.

As far as individual parts of the different execution games functionally match each other, they are with provided with the same reference numerals.

The first exemplary embodiment will first be described with reference to FIGS. 1 to 4.

The rail fastening device has a helically curved spring clip 1 , which is held at one end in a holding or anchoring device 2 and with another section rests on an insulating bracket 3 or directly on the top of a rail foot 4 . When using an insulation bracket 3 , this lies on the top of the rail foot 4 . The reference number 5 in FIG. 1 denotes a (cut) web of the rail.

The spring clip consists of several sections 6 to 14 . A first rectilinear anchoring portion 6 with a free end opens into a bent by approximately 180 ° from section 7, in turn, an anchoring portion parallel to 6 Ver extending, adjoining the straight straightforward in substantial abutment portion. 8 With a slight curvature vertically upwards, there is another straight-line section 9 , which in turn is followed by a section 10 bent by approximately 180 °, the bending radius of which is greater than the bending radius of section 7 . Section 10 is followed by a rectilinear, downwardly sloping section 11 , which slopes somewhat more steeply than section 9 rises. At the section 11 is followed by a support section 12 , which is flattened on its underside and in the assembled state against the top of the slide nenfußes 4 or the Iso lierwinkel 3 covering the rail foot presses. This flattened support section 12 can be produced by pressing or hot forging and is intended to produce a lower surface pressure than without flattening onto the plastic intermediate layer.

Due to the larger radius of section 11 (based on the radius of section 7 ) in the plan view of FIG. 2, sections 6 , 8 and 11 are such that the anchoring section 6 is approximately in the middle between sections 8 and 12 .

The support section 12 is followed by a further section 13 which is curved away from the web 5 of the rail and which opens into a stop section 14 which is responsible for the function of the overload protection. This stop section 14 engages under the transition area between sections 6 and 7 in the immediate vicinity of the exit of the anchoring section 6 from the anchoring device. The stop portion 14 is provided on its upper side with a flattening 19 , which stood in the normal operating position in a small amount 20 from the opposite surface of the anchoring portion 6 . This distance 20 be about 1-1.5 mm and represents the travel of the spring clip, which is traversed by the normal tension to the kink of the spring characteristic.

As can best be seen from FIGS. 1 and 3, the linear anchoring section 6 is inserted into an opening or bore 15 in the anchoring device 2 . On the side facing away from the rail foot 4 of the anchoring device, a step serving as an abutment 16 is present, on which the abutment section 8 of the spring clips rests. In the normal operating position, the spring clip 1 is thus mounted on three support areas, namely the support section 12 on the rail foot, the abutment section 8 on the abutment 16 and the anchoring section 6 in the bore 15 of the anchoring device 2 . The suspension thus contribute to sections 12 , 11 , 10 , 9 , 8 , 7 and 6 .

If the rail foot and thus the support section 12 are raised in the event of an overload, the sections 13 and 14 are also raised until the stop section 14 has passed through the distance 20 and comes to a stop against the anchoring section 6 . From this moment, in addition to the previously effective sections 6 to 12 , the other sections 13 and 14 are effective for the spring action, which have a shorter spring length or a lower effective lever arm for the suspension.

In FIGS. 3 and 4, to better appreciate the abutment 16, the tes for a support of the Widerlagerabschnit provides. 8 It can also be seen more clearly from FIG. 4 that the support section 12 is flattened as a whole, which can be done for example by thermoforming. The flattening 19 , which causes a lower surface pressure - in comparison to a line contact - can also be seen better from FIG. 4.

For the ne function of the neutralization position provided for by a further development of the invention, the first exemplary embodiment provides that a part pointing towards the free end of the anchoring section 6 opens out via a slope 17 into a flattened part 18 , which is opposite the upper wall of the bore 15 has a distance 21 .

If the spring clip is moved so far against the direction of impact that the anchoring section 6 is partially pulled out of the bore 15 , the flattened part 18 comes after passing through the distance 21 to the stop against the opposite wall of the bore 15th The spring clip is relieved and no longer exerts any significant pressure on the rail foot. In this "neutralization position" the track can be straightened and neutralized. Subsequently, the spring clip is pushed back completely into the bore 15 by hammer blows on the section 7 , the anchoring section 6 being pressed down again by the distance 21 by the bevel 17 and the required clamping force in the support section 12 being restored.

Finally, it is pointed out that the section 10 is so high relative to the anchoring device 2 that it is arranged with its inner radius area about 5-9 mm above the top of the anchoring device, so that the spring clip is slidable approximately anchoring device.

Although not shown in the drawing, it should be noted that also in this embodiment, a security against slipping out can be provided, which is described in more detail below in connection with the other embodiment ( Fig. 7f). This hedging tion can consist, on the one hand, in that the anchoring section 6 is extended to such an extent that in the working position it also protrudes from the other side of the bore 15 and has a thickening at its free end with run-up bevels, which as one only additional force to be overcome lock acts against a complete pulling out or slipping out of the spring clip from the anchoring device. Another variant provides that the flattened area 18 has a corrugation which increases the frictional force for further pulling out as soon as the flattened area comes into contact with the inner wall of the bore. In both cases, protection against slipping out can thus be achieved by modification of the spring clip alone, without any design changes to the anchoring device having to be made.

Figs. 5 to 7 show a second embodiment of the invention, which also operates approximately facilities with conventional anchoring and, for example of the execution of the Fig. 1 to 4 essentially in discriminates that the decisive for the overload protection stopper portion (14) of the spring clip is inserted into the bore 15 of the anchoring device and thus runs parallel to the anchoring section 6 . In the normal operating state, these two sections 6 and 14 inserted into the vertically oval bore 15 have a distance 20 ( FIGS. 6 and 7a) from one another which corresponds to the distance 20 of the first exemplary embodiment.

As best seen from Fig. 5, the spring clip 1 according to the second embodiment, bent so that the in the vertical oval-shaped opening 15 of the anchoring approximately device 2 inserted anchoring portion 6 and the person responsible for the overload protection stopper portion 14 parallel to one another are . The two curved sections 7 and 13 thus have the same bending radius in the plan view ( FIG. 5), which is then just half the size or smaller than the bending radius of section 10 . The spring clip 1 is thus symmetrical in the top view of FIG. 5.

The sectional view of FIG. 6 shows that the two sections 6 and 14 inserted into the vertically oval opening 15 lie one above the other and in the normal operating position, which is shown in FIG. 6, are at a distance 20 from one another which is approximately 1- Is 1.5 mm and represents the spring travel of the spring clip 1 , which must be run through before the overload protection takes effect. The two sections 6 and 14 are provided on their opposite sides with a flat 22 and 23 , respectively. Depending on the shape of the opening 15 , the underside of the stop section 14 can also be flattened abge. The top of the upper Verankerungsab section 6 is also substantially adapted to the contour of the opening in order to obtain a larger bearing surface.

As can best be seen from FIG. 7a, the anchoring section 6 is also provided in the region of its free end via a bevel 17 with a flattening 18 which ensures the “neutralization position”. The flattened portion 18 can be provided with corrugation in order to secure against slipping out in the neutralizing position.

Another type of securing against slipping out is shown in FIG. 7b. A short projection 31 protrudes from the abutment 16 and is provided in a correspondingly shaped recess 32 or 33 on the side of the abutment section 8 lying on the abutment 16 . In the operating position shown in Fig. 7b, the projection 31 is engaged in the recess 33 , which is attached in the transition region between the sections 7 and 8 . In order to pull the spring clip out of the anchoring 2 , additional forces are required which raise the abutment section 8 to such an extent that it slides over the projection 31 . Such forces do not occur in normal operation. If the spring clip 1 is brought into the neutralizing position ( FIG. 7g), the projection 31 engages in the recess 32 , so that even in this tensioned neutralizing position the spring clip only by additional force, for. B. by a displacement tool, can be completely pulled out of the anchoring device. The depressions 32 and 33 can be embossed during the hot deformation of the spring clip or can also be added subsequently by grinding, filing or other machining methods. The projection 31 , which is not present in the conventional anchoring devices used today, can be attached in a simple manner by cladding (for weldable steel) or by fine grinding.

In Fig. 7c, the spring clip is shown in the overload position. It can be clearly seen that the lower stop section 14 has come to rest against the anchoring section 6 .

In Figs. 7d and 7e of the bearing portion is easier to recognize 12 of the spring clip on the rail foot. 4 It can also be seen that the flattening in the support section 12 is adapted to the inclination of the rail foot relative to the horizontal.

Fig. 7f shows a further variant of a prevent slipping out. For this purpose, the upper anchoring section 6 inserted into the opening 15 is provided with an extension 24 which protrudes from the opening 15 in the operating position of the spring clip. The free end of this extension has a thickening 26 which has bevels 25 and 27 on both sides which allow it to be pulled out of the opening 15 or inserted into this opening. The region of the anchoring section 6 and 6 lying between the two bevels 17 and 25 the exten tion 24 has a length 29 which corresponds at least to the length of the bore 15 . This ensures that in the neutralizing position ( Fig. 7h), the two bevels 17 and 25 are outside the bore 15 and the Ver anchoring section 6 with the extension 24 can spring up to relieve the spring clip. The height of the thickening 26 is selected so that it protrudes by a height 28 over the flat 18 , so that the bevel 25 comes to a stop on the outside of the bore 15 . A complete pulling out of the spring clip from the opening 15 is still possible due to the bevel 25 , since with an appropriate force the anchoring section 6 and the extension 24 are pressed down so far that the thickening 26 can enter the bore 15 . In this variant, the protection against slipping out is achieved solely by changing the spring clips, without the anchoring device 2 having to be modified in any way.

Figs. 8, 9 and 10 show a third Ausführungsbei game, which differs from the two preceding in Wesent union that for the overload-protective stopper portion 14 is shorter and sammenwirkt with a recess in the anchoring device 2. The functions of overload protection and protection against slipping out are realized by this impact section 14 in cooperation with a special design of the anchoring device.

To the extent that some of the parts shown in FIGS. 8 to 10 match those of the exemplary embodiments discussed above, reference is made to the above description in order to avoid repetitions. Therefore, essentially only the deviations of the third exemplary embodiment are therefore dealt with here.

As can be seen from FIGS. 8 and 10, the support section 12 is followed by a section 13 bent by 90 degrees, which opens into a short stop section 14 standing perpendicular to the center line of section 6 . These length ratios with shortened sections 13 and 14 compared to the other exemplary embodiments result in favorable force or voltage distributions.

The stop section 14 is responsible for the functions overload protection, neutralization position and protection against slipping out, in connection with the details of a foot-side anchoring area 34 of the anchoring device 2 described below.

The anchoring device 2 has a base plate 34 , from which a tunnel-shaped elevation 35 projects, into the opening 15 of which the anchoring section 6 of the spring clips is inserted. In Fig. 8 it can be seen that the tunnel-shaped elevation 35 is rhomboidal in plan and on its outside facing the rail in the area of one of the corners of the rhombus, specifically where the rhombus forms an acute angle, has a recess 36 into which the stop section 14 of the spring clip 1 engages. The height of the recess 36 is greater than the height of the stop section 14 , so that there is a free space or play 37 (which corresponds to the distance 20 of the other two embodiments), which allows the section 13 together with the stop section 14 to the Amount of the game 37 , e.g. B. 1-2 mm can be raised. As soon as this game 37 has passed, the top of the section 14 stops against the opposite wall of the recess 36 , whereby the spring travel of the spring clip is limited and further tilting or lifting of the rail is prevented. In this way, a safe overload protection is realized, which results in a progressive spring characteristic.

The recess 36 is open to the insertion side, so that by longitudinal displacement of the spring clip 1 (parallel to the longitudinal axis of the rail) with respect to the device Halteinrich 2, the projection 14 leads out of the recess 36 . Subsequent to the underside 38 of the recess 36 , the base plate 34 of the holding device 2 has a run-up slope 39 which, when the spring clip 1 is displaced, causes the stop section 14 and thus also the support section 12 to be raised . Between the underside of the stop section 14 and the lower side 38 of the recess 36 , a free space is provided to ensure that the underside of the section 14 is in the operating position of the spring clip unhindered and does not abut the base plate, so that the support section 12 with the full Spring force of the clip presses against the rail foot. This free space corresponds functionally to the distance that the stop section 14 in the second exemplary embodiment (see FIGS. 6 and 7a) has in normal operating position relative to the underside of the drilling 15 . Due to the ramp 39 , the support section 12 is lifted off the rail and brought into the "neutralizing position", which relieves the rail foot 4 to such an extent that the rail can be neutralized.

In this neutralization position, the underside of the stop section 14 rests on a depression 40 (cf. position 14 '), which is higher in the side view or in the section of FIG. 9 than the bottom 38 of the recess 36 .

Subsequent to the recess 40 , the base plate has a further nose-shaped elevation 41 , which serves as a stop against further displacement of the spring clip and thus as a safeguard against slipping out. The deepening 40 already fulfills this function.

In order to apply the required clamping force, a support point B is provided in the transition area between the sections 7 and 8 of the spring clip 1 and an elevation on the base plate, which serves as an abutment 16 . The spring clip also has three contact areas here:

• 1. Straight anchoring section 6 against the downward facing wall of the opening 15 of the tunnel-shaped elevation 35 (see also points C and E in Fig. 10);
• 2. abutment 16 in cooperation with the abutment section 8 of the spring clip (see point B in Fig. 8); and
• 3. Support of the support section 12 against the slide nenfuß 4 or an isolation bracket (see. Point A in Fig. 8).

In addition, in the event of an overload, the stop between the stop section 14 and the wall of the recess 36 opposite this is used (see point D in FIG. 8).

The "action line" or "support action line" is shown here the points A-C-B formed. This line of action is here essentially perpendicular to the longitudinal direction of the rail.  

It should also be pointed out that the distance AD should be made as small as possible, so that only slight additional voltages occur in the spring clip in the event of an overload. In contrast to Examples 1 and 2, where an overload increases in accordance with the rigidity ratios between the areas in the event of an overload 12 over 10 , 8 after 6 and 12 over 13 , 14 after 6 (which should be taken into account when choosing the clip thickness, the bearing force and the spring travel), the increase in tension in the spring clip must be controlled in Example 3. If points A and D coincided, there would be no increase in tension in the spring clip in the event of an overload.

In all three examples, the distance A-C should be as possible be small, which depends on whether on the An insulating bracket lies on the rail base or not.

The "support line of action" ACB should be such that the bending and torsional stresses in the clip areas 10 and 7 become approximately the same. Are z. For example, if the distances AC and CB are the same, the bearing force in C is just twice as large as in A, since the "lever arm" AB is twice as long as the "lever arm" BC. Accordingly, the torsional and bending stresses which are distributed along the regions 10 and 7 are the same.

To further improve protection against slipping out, it is provided here that the free end of the straight-line anchoring section 6 is lowered somewhat in the area of point E, for example by 2 mm, as a result of which the support is clearly defined along the line of action ACB and the point E by torsion of the Spring clips only come into contact when the overload protection is effective.

The anchoring device 2 can also be welded to existing, rolled plates. It can also be welded to stamped, appropriately curved anchorages made of mild steel.

The illustrated examples of the invention relate to most of the cast anchors used for tracks on concrete sleepers. However, there are also rolled plates made of easily weldable steel, onto which a drop-forged part, which includes areas 38 , 39 and 40 , can be welded, even if they are in the track. Furthermore, the areas 38 , 39 and 40 can also be punched out at the same time, even with punched out anchoring plates.
