(12) FIG. 11 shows a detail of the clamping means and of the vibration absorber thereof according to FIG. 10.

(13) In the figures of the drawings, identical, functionally identical and identically operating elements, features and components are respectively provided with the same reference numerals, unless indicated otherwise.

(14) FIG. 1 is a perspective view of a rail 1 with a vibration absorber arrangement 2 according to a first embodiment of the invention. The vibration absorber arrangement 2 has at least one clamping means 3 with at least one vibration absorber 4, and at least one clamp 5 for fastening the clamping means 3 and the vibration absorber thereof 4 to the rail 1.

(15) The clamp 5 described in the following with reference to FIGS. 1 to 11 is a spring clip which is formed integrally or in one piece. Furthermore, the spring clip is made of spring steel, for example round spring steel or flat spring steel.

(16) In the embodiment shown in FIG. 1, the vibration absorber 4 consists for example of an absorber packet 6 which is fastened to the clamping means 3, for example by vulcanisation and/or by screwing using one or more screws 7. The absorber packet 6 in FIG. 1 consists of a plurality of metal plates, for example steel plates, between which at least one resilient layer, for example a rubber layer, is provided. The metal plates are arranged parallel or substantially parallel to the clamping means 3 and to the rail 1 to be damped.

(17) The vibration absorber 4 can be adapted to the rail 1, for example by the number of steel plates and by the resilient characteristics of the rubber mixture of the respective rubber layer. However, the invention is not restricted to a vibration absorber 4 of this type, but any other suitable vibration absorber can be used to absorb vibrations in rails.

(18) As shown in FIG. 1, the rail 1 has a foot 8 and a head 10 which are interconnected by a web 9. The vibration absorber 4 is respectively arranged on opposite sides of the rail web 9.

(19) For this purpose, the previously mentioned clamping means 3 is respectively provided, for example in the form of an angled plate shown in FIG. 1. The clamping means 3 is made of metal and for example a steel plate or a cast part. The vibration absorber 4 is fastened to the outside of the clamping means 3, for example by screws 7, as shown in FIG. 1. The clamping means 3 is arranged with its inside on the rail 1 and is fastened or clamped to the rail 1 by at least the clamp 5.

(20) In the embodiment shown in FIG. 1, the clamping means 3 has a portion 11 for attaching at least one vibration absorber 4, to which the rail absorber 4 is attached, and a clamp fastening portion 12, on which the clamp 5 can be fitted to attach the clamping means 3. As shown in FIG. 1, the clamping means 3 is arranged with its rail absorber fastening portion 11 on the rail web 9 and with its clamp fastening portion 12 on the rail foot 8. As shown in the embodiment in FIG. 1, the clamp fastening portion 12 can be square or, as in the embodiment shown in the following FIG. 5, it can be configured for example with cut-off corners. However, the invention is not restricted to these configurations of the clamping means 3. The clamp fastening portion 12 can have any other shape which is suitable for fastening the clamping means 3 to a rail 1 by at least one clamp 5.

(21) As shown in FIG. 1, at least one additional damping layer 13 consisting for example of rubber or another suitable material or material combination can optionally be provided on the inside of the clamping means 3. Furthermore, a damping layer 13 of a resilient material, such as rubber, allows tolerance differences in the spacing between the inside of the clamping means 3 and the outside of the rail 1 to be compensated, so that the clamping means 3 can rest on the rail 1 without an air gap inbetween in a support portion provided for this purpose.

(22) Furthermore, as previously described, the clamp 5 is provided for attaching the clamping means 3 and the vibration absorber 4 thereof to the rail 1. The clamp 5 is configured such that it encompasses the foot 8 of the rail 1 and can be brought into contact by one end with the clamping means 3 or with the clamp fastening portion 12 thereof, such that it presses the clamping means 3 against the rail 1, as shown in FIG. 1. For the rail 1 shown in FIG. 1, the clamping means 3 is fastened with its vibration absorber 4 to the rail 1, for example by two clamps 5, in each case one clamp at each end of the clamping means 3. If one clamping means 3 with at least one vibration absorber 4 is fitted on each side or longitudinal side of the rail 1, the clamps 5 for the two clamping means 3 can be mounted inserted one inside the other for example, as shown in FIG. 1 and in the following FIGS. 3 to 7.

(23) Furthermore, FIG. 2 is a perspective view of the clamp 5 for fastening the clamping means 3 and the vibration absorber 4 thereof to the rail 1 according to FIG. 1.

(24) As shown in FIG. 2, the clamp 5 has a first arm 14 and a second arm 15 which are interconnected at one end 16. The two arms 14, 15 together form a U shape with a closed end 16 and an open end 17. The open end 17 of the clamp 5 has the advantage that the clamp 5 can be mounted after being put together with a further clamp 5, as previously described with reference to FIG. 1.

(25) The first and second arms 14, 15 have a respective first portion 19 and a second portion 20 and a centre portion 18 which is arranged inbetween and extends along the underside of the rail foot 8 in the transverse direction of the foot 8. As shown in FIG. 2 and in the following FIG. 3, the centre portion 18 can be configured such that, when assembled, it rests at least partly on the underside of the rail foot 8 and is also prestressed against the rail foot 8. In this respect, the centre portion 18 of the arms 14, 15 can rest on the rail foot 8, offset with respect to the centre of the foot 8, preferably prestressed against the foot 8, as shown in FIG. 3, or it can rest on the rail foot 8 in the centre thereof, preferably prestressed against the foot 8, as shown in the following FIG. 6.

(26) The first portion 19 is configured such that it extends upwards from the centre portion 18 along a side 21 of the rail foot 8, for example it extends substantially vertically upwards, to engage or to hook the clamp 5 around this side 21 of the rail foot 8.

(27) The second portion 20 in turn is configured such that it extends upwards from the centre portion 18 along the opposite side 22 of the rail foot 8, for example it extends substantially vertically upwards, to engage or to hook the clamp 5 around this side 22 of the rail foot 8, the second portion 20 then also extending over the clamping means 3 such that it engages around the clamping means 3 and, when mounted, presses against the rail 1.

(28) Furthermore, the first and second portions 19, 20 can also be configured such that, when assembled, they are also pressed apart (not shown) by the rail foot 8 to fasten the clamp 5 on the rail foot 8.

(29) In the embodiment shown in FIG. 2 and in the following FIG. 3, the second portion 20 is configured such that, when assembled, it is prestressed against the clamping means 3 and it presses the clamping means 3 against a portion of the rail 1, for example against the rail foot 8, the rail web 9 and/or the transition region 23 between the foot 8 and the web 9.

(30) FIG. 3 is a front view of the rail 1 and of the clamping means 3, fastened thereto, with the vibration absorbers 4 thereof according to FIGS. 1 and 2.

(31) As described previously with reference to FIG. 1, at least one damping layer 13 is arranged between the clamping means 3 and the outside of the rail 1. The damping layer 13 is attached, for example vulcanised or affixed to the clamping means 3, to name but a few of many possibilities, to provide the clamping means 3 with the damping layer 13. In principle, the damping layer 13 can also be inserted for example as a separate part between the clamping means 3 and the rail 1 or can be affixed to or vulcanised on the rail 1.

(32) In the embodiment shown in FIG. 3, the contour of the inside of the clamping means 3, by which this is fastened to the rail 1, corresponds for example to the contour of the outside of the rail 1. Accordingly, the clamping means 3 rests with the damping layer 13 fully on the rail 1. Alternatively, the clamping means 3 can also rest with the damping layer 13 only on at least a portion of the rail 1, for example on a portion 23 of the transition between rail foot 8 and rail web 9, on a portion of the rail web 9 and/or on a portion of the rail foot 8, as indicated in FIG. 3 by a dashed line.

(33) Furthermore, the clamping means 3 extends partly or substantially completely over the upper side 24 of the rail foot 8, as shown in FIG. 3.

(34) As shown in the embodiment in FIG. 3, a lip or a holding projection 25 can optionally also be provided on or next to a terminal edge 30 of the clamp fastening portion 12 of the clamping means 3. The holding projection 25 is positioned such that, when the clamp 5 is mounted, it is positioned between the arms 14, 15 of the clamp 5. The holding projection 25 also has a suitable height so that, during dismantling, the clamp 5 can initially remain hanging from the holding projection 25 by its closed end 16 or can be held by the holding projection. This prevents the clamp 5 from inadvertently flying off during the dismantling procedure.

(35) The projection 25 can be attached, for example by bonding, vulcanising etc., to the terminal edge 30 as a separate part consisting of rubber, for example. Likewise, the projection 25 can also be formed in one piece or integrally with the clamping means 3.

(36) A further embodiment of the projection 25 is described in the following FIGS. 10 and 11.

(37) The outside of the clamping means 3 can also be configured with at least one lateral stop 26 for the clamp 5 in the form of a projection. The stop 26 on one side of the clamp 5 serves to prevent or restrict the lateral movement of the clamp 5 or the movement of the clamp 5 in the longitudinal direction of the clamping means 3 and of the rail 1.

(38) FIG. 4 is a side view of the rail 1 and of the vibration absorber arrangement 2 according to FIG. 1.

(39) As shown in FIG. 4, the clamping means 3 or the clamp fastening portion 12 thereof has the stop 26 in the form of a projection on each side of the clamp 5 in the longitudinal direction, to fix the clamp 5 in the longitudinal direction of the clamping means 3 and accordingly, when mounted, in the longitudinal direction of the rail 1. For this purpose, the clamp 5 is introduced by one end between the two stops 26 and is thereby prevented from inadvertently moving beyond the stops 26 in the longitudinal direction.

(40) In addition to or instead of the stops 26, as shown in FIG. 4, the clamping means 3 has on its outside a projection 27, to be encompassed by the clamp 5. The projection 27 can cooperate with the clamp 5 such that, in the mounted state, the clamp 5 is suspended or is loosely suspended by its closed end 16 from the projection 27 or alternatively is locked on the projection 27.

(41) The projection 27 on the outside of the clamping means 3 has the advantage that during removal or dismantling, the clamp 5 cannot inadvertently spring away. Furthermore, the clamp 5 can be positioned on and fastened to the clamping means 3 relatively easily in that it is suspended from or locked by its closed end 16 on the projection 27 of the clamping means 3 on one side 22 of the rail foot 8 and is hooked in by its open end 17 on the opposite side 21 of the rail foot 8.

(42) As the holding projection 25 is also provided on the terminal edge 30 of the clamp fastening portion 12 of the clamping means 3, as shown in FIG. 3 and in the following FIGS. 10 and 11, during the dismantling procedure, the clamp 5 can initially be held on the projection 27 and the clamp 5 can be prevented from inadvertently flying away. As soon as the clamp 5 is released from the projection 27, the clamp 5 can be held by the holding projection 25 and prevented from inadvertently flying away. As previously described, the clamp 5 can initially remain suspended from the holding projection 25 before it is completely removed from the rail and the clamping means 3.

(43) Since the respective first portion 18 of the clamp 5 only extends upwards along the side 21 of the rail foot 8, it can easily be pressed downwards to dismantle the clamp 5 and can thereby be disengaged from the rail foot 8. Consequently, the clamp 5 can be easily released by a user and the vibration absorber arrangement 2 can be quickly and easily dismantled again as required.

(44) FIG. 5 is a perspective view of a rail 1 with a second embodiment of a vibration absorber arrangement 2 according to the invention. FIG. 6 in turn is a side view of the rail and of the vibration absorber arrangement 2 according to FIG. 5. Here, the rail 1 is the same rail 1 as in FIGS. 1 to 4. Reference is made to the description of FIGS. 1 to 4 with respect to the common features of the first and second embodiments, to avoid unnecessary repetition.

(45) The vibration absorber arrangement 2 according to the second embodiment differs from the vibration absorber arrangement according to the first embodiment in that the clamp fastening portion 12 of the clamping means 3 according to the second embodiment has cut-off corners 28. This has the advantage that the clamping means 3 is lighter and nevertheless can be fastened to the rail 1 with a respective clamp 5 at the end.

(46) The vibration absorber 4 according to the second embodiment also differs from the vibration absorber 4 according to the first embodiment in that the absorber packet 6 in the second embodiment, as shown in FIG. 5, is attached to the clamping means 3 by vulcanisation or adhesive bonding instead of by screwing, as in the first embodiment.

(47) Furthermore, the form of the clamp 5 of the second embodiment differs from the form of the clamp 5 of the first embodiment, as will be described in more detail in the following with reference to FIGS. 6, 7 and 8.

(48) In addition, the second embodiment does not have any additional stops for laterally fixing the clamp 5, as in the first embodiment, but only the projection 27 in each case, as indicated by a dotted line in FIG. 5, to be encompassed by the closed end 16 of the clamp 5. As previously described, when mounted, the clamp 5 is for example merely loosely suspended from or locked on the projection 27. As previously described, the advantage of the projection 27 is that it prevents the clamp 5 from undesirably springing off during the dismantling procedure.

(49) FIG. 7 is a side view of the rail 1 and of the clamping means 3, fastened thereto, with the vibration absorbers 4 thereof.

(50) At least one additional damping layer 13 can optionally also be arranged between the clamping means 3 and the outside of the rail 1, as shown in FIG. 7.

(51) In the embodiment shown in FIG. 7, the contour of the inside of the clamping means 3, by which this is fastened to the rail 1, corresponds for example to the contour of the outside of the rail 1. The clamping means 3 can also rest with the damping layer 13 only on at least a portion of the rail 1, for example on a portion or transition region 23 between rail foot 8 and rail web 9, on a portion of the rail web 9 and/or on a portion of the rail foot 8, as indicated in FIG. 7 by a dashed line.

(52) Furthermore, the clamping means 3 extends with its clamp fastening portion 12 at least in part or completely as far as the side 22 of the rail foot 8, as shown in FIG. 7.

(53) To fasten the clamping means 3 with its rail absorber 4 on the rail 1, the clamp 5 in the second embodiment, like the clamp 5 according to the first embodiment, has a first arm 14 and a second arm 15 which are interconnected at one end. The two arms 14, 15 together form a U shape with a closed end 16 and an open end 17.

(54) The first and second arms 14, 15 have a respective first and second portion 19 and 20 and a centre portion 18 inbetween. The centre portion 18 extends along the underside of the rail foot 8 in the transverse direction thereof.

(55) As shown in FIG. 6, the centre portion 18 can be configured such that when assembled, it rests at least in part on the underside of the rail foot 8 and is optionally also prestressed against the rail foot 8. As previously shown in FIG. 3, the centre portion 18 of the arms 14, 15 can rest on the rail foot, laterally offset with respect to the centre of the foot 8, and optionally also prestressed against the foot 8, or it can rest on the rail foot in the centre of the foot 8, and can optionally also be prestressed against the foot, as shown in FIG. 6.

(56) The first portion 19 of the clamp arms 14, 15 is configured such that it extends upwards from the centre portion 18 along a side 21 of the rail foot 8 to engage or to hook the clamp 5 around this side 21 of the rail foot 8. The first portion 19 is also slightly curved outwards preferably with its outer end 29 or, as shown in the following FIGS. 7 and 8, is bent away outwards from the clamping means 3 or the rail 1. This has the advantage that during assembly, the rail 1 is also protected against undesirable nicks caused by sharp-edged ends of the clamp 5.

(57) The second portion 20 in turn is configured such that it initially extends upwards from the centre portion 18 along the opposite side 22 of the rail foot 8 to hook onto the rail foot 8 and then extends along the clamping means 3. As shown in FIG. 6, the second portion 18 bends, for example downwards, to the clamping means 3 to press the clamping means 3 against the rail 1 in the assembled state.

(58) Furthermore, the first and second portions 19, 20 can optionally be configured such that, when assembled, they are pressed apart, as shown in FIG. 7, and are laterally prestressed against the rail foot 8 to fasten the clamp 5 on the rail foot 8.

(59) In the embodiment shown in FIG. 7, the second portion 20 is configured such that it is prestressed against the outside of the clamping means 3 and, when assembled, it pushes or presses the clamping means 3 against the rail 1, for example against the rail foot 8, against the rail web 9 and/or against the transition region 23 between the foot 8 and the web 9.

(60) FIGS. 8 and 9 show a further embodiment of the clamp 5 according to FIGS. 5, 6 and 7. FIG. 8 is a side view of the clamp 5 and FIG. 9 is a perspective view. The clamp 5 according to the embodiment in FIGS. 8 and 9 differs from the clamp 5 in FIGS. 5, 6 and 7 only in that the outer ends 29 of the clamp 5 are bent outwards or are bent away from the clamping means 3 and thereby from the rail 1, thereby making it possible to avoid undesirable nicks in the rail 1 when the clamp 5 is fitted.

(61) Furthermore, FIGS. 10 and 11 show a clamping means 3 and a vibration absorber 4 according to a vibration absorber arrangement of the invention. FIG. 10 is a perspective view and FIG. 11 shows a detail of the clamping means 3 and of the vibration absorber 4 attached thereto.

(62) The clamping means 3 has a fastening portion 11 for the at least one vibration absorber 4 and a clamp fastening portion 12 for fastening at least one clamp 5. Furthermore, as shown in the embodiment in FIGS. 10 and 11, the clamping means 3 optionally has an additional damping layer 13 on its underside. This additional damping layer is attached to the underside of the clamping means 3 for example by affixing, vulcanising etc.

(63) In addition, the clamping means 3 has on the outside of its clamp fastening portion 12 a projection 27 to be encompassed by the closed end 16 of the clamp 5, and also has on both sides of the projection 27 in the longitudinal direction of the clamping means 3 a respective stop 26 for restricting the movement of the clamp 5 in the longitudinal direction. The projection 27 and the stops 26 have been previously described with reference to FIGS. 3, 4 and 6 and have been shown therein.

(64) The holding projection 25, as previously described with reference to FIG. 3, is configured in the embodiment as shown in FIGS. 10 and 11 for example as a clamp element 31 with an elevation 32. Here, the clamp element 31 has a U shape for example, by which it is attached or clamped on the terminal edge 30 of the clamp fastening portion 12 and additionally or alternatively is bonded with the clamping means 3 and/or is vulcanised thereon. The elevation 32 of the clamp element 31 is arranged on the upper side of the clamping means 3 such that it aligns with the projection 27.

(65) In a further embodiment, instead of being provided in the longitudinal direction of the clamping means 3 next to the projection 27, the stop 26 can also be provided next to the holding projection 25 to prevent an undesirable sideways movement of the clamp.

(66) The stop 26 can be arranged next to the holding projection 25 or, in a further embodiment, it can also be directly formed on the holding projection 25, as indicated in FIG. 11 by a dashed line. The holding projection 25 can be formed on both sides with the stop 26 instead of being formed on only one side, as shown in FIG. 11.

(67) Therefore, the stop 26 which is shown in FIG. 11 and is arranged on the side of the projection 27 in the longitudinal direction of the clamping means 3 can be omitted.

(68) The holding projection 25 can be formed in one piece with the stop 26, for example from metal and/or rubber, and can be attached to the clamping means 3. Likewise, the clamping means 3, together with the holding projection 25 and the stop 26 thereof can be formed in one piece from metal.

(69) With a metal holding projection 25 and stop 26, a gap 33 is provided between the elevation 32 of the holding projection 25 and the stop 26 to receive the respective arm of the clamp. However, if the holding projection 25 and the stop thereof are made of a resilient material such as rubber, it is then also possible to dispense with the gap 33, for example.

(70) In the assembled state, a clamp for fastening the clamping means 3 to a rail encompasses the projection 27 with its closed end, the holding projection 25 being arranged on the inside of the arms or between the arms of the clamp. As soon as the closed end of the clamp slips down from the projection 27 during the dismantling procedure and moves in the direction of the terminal edge 30 of the clamping means 3, the closed end of the clamp initially remains suspended from the holding projection 25 and consequently cannot inadvertently spring away.

(71) Instead of a clamp element 31 with an elevation 32 as shown in FIGS. 10 and 11, an elevation of this type can also be attached to the upper side of the clamping means without the clamp element 31 or can be formed in one piece with the clamping means 3 (not shown).

(72) The holding projection 25 can be clamped, affixed and/or vulcanised on the clamping means or alternatively can be formed in one piece with the clamping means. As previously described, the holding projection 25 has the advantage that during the dismantling procedure, the clamp can also remain suspended from the holding projection 25 so that it does not inadvertently fly off. Furthermore, during preassembly, the clamp can initially engage on the holding projection 25 so that it cannot slip down. Thus, the clamp 5 can subsequently be easily assembled with a suitable device.

(73) Although the present invention has been described above with reference to the preferred embodiments, it is not restricted thereto, but can be modified in many different ways. In particular, the previously described embodiments can be combined with one another, particularly individual features thereof.

(74) In particular, in the previously described embodiments according to the invention of the vibration absorber arrangement, the clamps, vibration absorbers and/or clamping means of the individual embodiments can be combined with one another.
