    The invention relates to a pull-out for a furniture body extendable from a furniture part comprising a first guide rail and a second guide rail which is slidably mounted relative to the first guide rail in and against a displacement direction via a displacement, wherein the deceleration of the second guide rail at least at one end of the displacement path is damped by a arranged on one of the guide rails stop damper, to which a arranged on the other guide rail counter-stop element starts.
    It is known to provide at Ausziehführungen for extendable furniture parts, especially drawers or cabinet drawer, damping devices, whereby the braking is damped at least at one end of the displacement. For example, linear dampers in the form of piston-cylinder units and rotary dampers are known, which dampen the insertion of the guide rail over a last portion of the displacement, such damping devices are often combined with self-closing devices.
    A disadvantage of such cylinder or rotary damper is their space requirement. An installation in the pull-out is not possible in many configurations of pull-out and an arrangement outside the pull-out is often disturbing. In addition, such cylinder or rotary damper increase the pull-out.
    Also known is a use of elements made of elastomeric materials, in particular rubber elements on parts in contact with each other. Due to the design, however, the abutting abutment surfaces are often relatively small, and it is precisely in the case of extension guides, which are designed for a higher load-bearing capacity, that a relatively rapid wear of such rubber abutment elements occurs during operation.

    Pull-out guides are e.g. in the form of Rollenausziehführungen known, in which the serving for the displacement rollers are rotatably mounted on the rails about these stationary axes. Differential-type roller pull-out guides have a load-transmitting differential roller rotatably mounted on the center rail, thereby achieving synchronized or differential travel of the rails. In this case, the middle rail only covers half the path of the pull-out rail with respect to the carcass rail. Such roller differential extension guides are known for example from AT 391 603 B and EP 1 360 914 A1.
    In the role-extension guides telescopic extensions are known as a further type in which all rails [astübertragende rollers are rotatably mounted and in which the pull-out and the center rail are pulled out one after the other from the carcass rail. In order to achieve a simultaneous extension of the guide rails, it is further known to use on the center rail a rotatably mounted and a window recess of the center rail passing through elastic drive roller, but does not represent a load-transmitting role. Such a telescopic extension with differential action is described for example in AT 392 883 B.
    In addition to roller pull-out guides, pull-out guides are known which have roller bodies fitted with rolling elements, e.g. Ball drawer guides. For example, EP 1 561 398 A1 discloses a spherical telescopic extension guide.
    The object of the invention is to provide a pull-out of the type mentioned, which has a damping device which can be integrated with relatively little space in the pull-out, with a long-lasting damping device can be realized even with provided for higher payload pull-out. According to the invention, this is achieved by a pull-out guide with the features of claim 1.
    REPLACED y
    In a pull-out according to the invention, the stop damper on a transmission part which is movably mounted relative to the guide rail on which the stop damper is arranged When starting the counter-stop element to the stop damper, the transmission part is moved against a restoring force of at least one elastic damping member made of an elastomeric material , A force exerted on the stop damper by the counter-stop element is thus transmitted via the transmission part to the at least one elastic damping part. In this case, the tarnishing of the counter stop element is damped against the stop damper. As the force exerted on the stop damper by the counter-stop element increases, a force-transmitting interaction of the transmission part or the counter-stop element with an end stop occurs as of a limit value of this force. It is thereby derived a part of the force exerted by the counter-stop element force on the end stop, and without this part of the force is transmitted via the at least one elastic damping part. This force transmitted directly to the end stop is higher, the higher the total force exerted by the counter-stop element. The load acting on the at least one elastic damping part is thereby reduced, so that its durability can be substantially increased when acting load peaks occur.
    In one possible embodiment, the stop damper is provided only for the damping of the deceleration of the second guide rail at one end of its displacement, so either at the end of the extraction or at the end of insertion. In another possible embodiment, both the deceleration of the second guide rail displaced into one of the displacement directions and the braking of the second guide rail counter to this displacement direction are damped by the stop damper at the respective end of the displacement path, that is to say the stop damper is at a displacement in the pull-out direction at the end of the displacement path as well as a shift in the insertion direction at the end of the displacement path effective. This runs at one end of the

    Move away a first counter-stop element and at the other end of the displacement path, a second counter-stop element to the stop damper {from the opposite side) to. The transmission part is thereby moved when starting the first counter-stop element and at the start of the second counter-stop element in opposite directions of movement or in the same direction of movement. When the limit value of the force exerted by the respective counter-stop element is exceeded, a respective limit stop becomes effective. For this purpose, the transmission part between the first and second end stops may be arranged and start at the respective end stop. On the other hand, this could also start a respective one of the first and second counter-stop elements to a respective first or second end stop.
    An advantageous embodiment of the invention provides that the transmission part relative to the guide rail on which the stop damper is arranged, starting from a starting position at least in the direction of either the extraction or the insertion, possibly also against this displacement direction (if the stop damper at both ends of Displacement path is effective) is displaceable. This can advantageously be achieved in that the elastic damping element or a respective one of the elastic damping elements in and against the displacement direction as a whole immovably on the guide rail on which the stop damper is arranged, wherein the transmission part over the damping element or the respective damping element with this Guide rail is connected. For example, for this purpose, the elastic damping element or a respective one of the elastic damping elements having an opening, in which engages a holding extension or a respective holding extension of the transmission part.
    In another advantageous embodiment of the invention, the transmission part, starting from a starting position at least in a pivoting direction, optionally in both pivot directions (if the

    Stop damper at both ends of the displacement path is effective) relative to the guide rail on which the stop damper is arranged to pivot about a pivot axis. The elastic damping element or a respective one of the elastic damping elements is conveniently arranged between the transmission part and a part of the guide rail supporting the elastic damping element or a respective one of the elastic damping elements, on which the stop damper is arranged.
    In a possible embodiment of the pull-out guide, this comprises only one attachable to a furniture body corpusfeste guide rail (as the first guide rail) and attachable to an extendable furniture part extendable guide rail (as a second guide rail). Such a pull-out guide may have a single effective at both ends of the displacement stroke damper, which is arranged on the corpus fixed guide rail or on the extendable guide rail or such pull-out guide may have two inventive stop damper, one of which at the end of the displacement in the pull-out and one at the end the displacement path is effective in the insertion direction, wherein each of the stop damper can be arranged on the body-fixed guide rail or on the extendable guide rail (in this case both stop damper can be arranged on the same rail or on different rails).
    In another possible embodiment of the pull-out guide, a middle guide rail is present between the body-fixed guide rail and the extendable guide rail. As a result, full or over excerpt can be realized. In this case, it can be arranged between the body-fixed guide rail and the middle guide rail (wherein the body-fixed guide rail represents the first guide rail and the middle guide rail is the second guide rail) and / or between the middle guide rail and the extendable guide rail (wherein the middle guide rail the first guide rail and the extendable Guide rail, the second guide rail represents) acting stop damper be provided in accordance with the invention. A later one; c: respective stop damper acts at the end of the displacement in the direction of insertion and / oram the end of the displacement in the pull-out direction. The insertion dampers can in turn be arranged on any of the two rails between which they act. An advantageous embodiment provides that there is a stop damper designed in accordance with the invention both between the body-fixed guide rail and the middle guide rail and between the middle guide rail and the extendable guide rail. Preferably, at least one designed according to the invention stop damper, which acts between the body-fixed guide rail and the middle guide rail, as well as an inventively trained stop damper, which acts between the middle guide rail and the extendable guide rail, arranged on the central guide rail. For example, all stop dampers of the pull-out guide can be designed in accordance with the invention and arranged on the middle guide rail.
    Preferably, the transmission part of the stop damper and / or the at least one counter-stop element cooperating with the stop damper and / or the at least one end stop, with which the transmission part or the at least one counter-stop element cooperates, consists of a material whose modulus of elasticity is at least ten times, particularly preferably at least one hundred times , greater than the modulus of elasticity of the at least one elastic damping part.

    An exemplary embodiment of a pull-out guide designed in accordance with the invention is shown in FIGS. 1 to 20. The pull-out guide is used for

    Extracting an extendable furniture part 1 from a furniture body 2, which are indicated only in Fig. 1 by dashed lines. The indicated pull-out furniture part 1 is a drawer. A pull-out guide according to the invention can also be designed, for example, to pull out cabinet extensions.
    On both sides of the pull-out furniture part 1 such pull-out guides are attached of which only one is shown and are formed in mirror image.
    Advantageously, a pull-out guide according to the invention can be designed for relatively high load-bearing forces. In particular, the load capacity of both sides of the pull-out furniture part arranged pull-out together can be more than 100kg.
    In the exemplary embodiment shown, the pull-out guide comprises a body-fixed guide rail 3 to be attached to the furniture body 2, a middle guide rail 4 and an extendable guide rail 5 to be attached to the extendable furniture part 1. The guide rails 3 and 4 and the guide rails 4 and 5 are each mounted to slide against each other.
    For mutually displaceable mounting of the rails 3, 4, 5 are shown in Ausführungsbeispie! all rollers rotatably mounted on the central guide rail 4. In this case, a differential extension is formed in a known manner, in which the middle guide rail 4 moves at half the speed of the extendable guide rail 5 when the extensible guide rail 5 is pulled out.
    The rollers comprise a front roller 8 rotatably mounted relative to the displacement direction 6 of the extension in the region of the front end of the guide rail 4, a rear roller 9 rotatably mounted in the region of the rear end of the guide rail 4, one in a central region of the guide rail 4
    AFTER REPLACEMENT rotatably mounted central roller 10, one next to the central roller 10 arranged with play rotatably mounted differential roller 11 and above the differential roller 11 rotatably mounted support roller 12. Furthermore, a game rotatably mounted with auxiliary roller 13 is conveniently present, which in a region of the longitudinal extent the central guide rail 4 is rotatably mounted, which lies between the rear roller 9 and the middle roller 10.
    The extendable guide rail 5 comprises a support web 14 for supporting the extendable furniture part 1, a catwalk 15 and a connecting web connecting the support web with the catwalk 15. The catwalk 15 has on its underside a track for the front roller 8 and the differential roller 11 and on its upper side a track for the support roller 12. The support web 14 could also be omitted and carried the connection with the extendable furniture part 1 via the connecting web 16.
    The corpusfest guide rail 3 comprises an upper catwalk 17 and a lower catwalk 18, which are interconnected by a connecting web 19. The upper catwalk 17 has on its underside a track for the rear roller 9. The lower catwalk 18 has on its upper side a track for the differential roller 11, the middle roller 10 and the auxiliary roller 13.
    Preferably, the rollers 8-13 are rotatably mounted about horizontal axes and the catwalks 15,17 and 18 aligned horizontally.
    Instead of in the form of a differential extractor having a load-bearing differential roller 11 rotatably mounted on the center rail, the mutually displaceable mounting of the guide rails 3, 4, 5 could also be done in other ways, for example by means of a differently configured roller extension, in which the guide rails pass through at least one of the guide rail rotatably mounted rollers are mutually displaceable, wherein the rollers are rotatably mounted to the respective guide rails stationary axes. Another such roller pullout guide is e.g. a telescopic extension,
    POSSIBLE REPLACEMENT • · ♦ • * in which rollers are rotatably mounted on all guide rails and the guide rails are pulled out one after the other. The invention may also be applied to other types of extension guides than to roller extension guides, in particular to pull-out guides having rolling element loaded carriages, e.g. Kugelausziehführungen.
    The mutual displacement of the central guide rail 4 relative to the body-fixed guide rail 3 and the extendable guide rail 5 relative to the central guide rail 4 is limited in the direction of displacement of the extension 6 and in the opposite direction of displacement 7 of the insertion respectively by stops, wherein the rails between the attacks each about a displacement are mutually displaceable.
    The displacement of the extendable guide rail 5 relative to the central guide rail 4 is limited in the direction of displacement 6 of the extension by starting a first, arranged on the extendable guide rail 5 counter-stop member 20 to a arranged on the central guide rail 4 stop damper 22. In the direction of displacement 6 oppositely directed displacement direction 7 of insertion, the displacement of the extendable guide rail 5 relative to the central guide rail 4 by starting a second, arranged on the extendable guide rail 5 counter stop element 21 is limited to the same stop damper 22. The stop damper 22 damps the braking of the displaced in the direction of displacement 6 and in the direction 7 extendable guide rail 5 at the respective end of the displacement.
    The stop damper 22 comprises a rigid transmission part 23 which is movably mounted relative to the guide rail 4. For this purpose, the transmission part 23 is connected to the guide rail 4 via elastic damping parts 24, 25, which consist of an elastomeric material. These are held immovably on the guide rail 4 as a whole.

    To connect the transmission part 23 with the elastic damping parts 24, 25, the transmission part 23 has hook-shaped retaining extensions 26, 27, which are inserted into an insertion opening 28 of the respective damping part 24, 25. The holding projections 26, 27 extend in a direction which is perpendicular to a direction in which a stop extension 29 extends, which cooperates with the counter-stop elements 20, 21. The holding projections 26, 27 are in this case arranged on a holding web 30 and lie with this in a common plane which is perpendicular to the plane in which the stop extension 29 is located.
    The connection of the stop damper 22 with the guide rail 4 takes place in the embodiment in a lower, U-shaped portion of the central guide rail 4, in which it has a window 31 for the passage of the stop extension 29.
    The U-shaped section is formed by a lower portion of the vertical web 32, the horizontal web 33 connected to the lower end of the vertical web 32 and the upward bead 34 of the horizontal web 33. The window is arranged in the embodiment in the horizontal web 33, but could additionally or instead be formed in the bead 34.
    The elastic damping parts 24, 25 are inserted into the intermediate space of this U-shaped portion and fixed in this by a snap part 35. The snap part 35 has arms 36 with snap-in lugs 37, which can be snapped into snap-in recesses 38 of the guide rail 4. Relative to the longitudinal extent of the guide rail 4 (ie in the direction of the displacement direction 6 or 7) is a respective elastic damping member 24, 25 between arms 36 of the latch member 35 and a tab 39 which is bent upward at the respective edge of the window 31 (cf. 12). Thus, the elastic damping members 24, 25 are held as a whole relative to the direction of the longitudinal extension of the guide rail 4. Relative to the directions perpendicular thereto, the elastic damping parts 24, 25 are penetrated by the vertical web 32 and the rearward directions
    Beading 34 and held by the horizontal web 33 and the cover 40 of the latch member 35 as a whole immovable.
    The stopper extension 29 has in the area in which it passes through the window 31, based on the direction of the longitudinal extension of the guide rail 4, a smaller width b than the width B of the window. The stop extension 29 has starting from the illustrated in Fig. 15 starting days, which he occupies without the action of counter-stop elements 20, 21, a game for a shift in the direction of displacement 6 and in the opposite direction of displacement 7. Advantageously, this game is at least 0, 3mm.
    As shown, a cap-shaped elastomer element 41 made of an elastomeric material may be attached to the stop extension 29 in order to additionally dampen the impact noise. Since the wear of this elastomeric element 41 is relatively high, e.g. It is also possible to provide an elastomeric element which can be pressed into a depression of the stopper extension 29 so that, when the forces are high, the counter-stop elements 20, 21 directly come into contact with the stopper extension 29. An elastomer element 41 could also be dispensed with.
    The counter-stop elements 20, 21 are rigidly attached to the extendable guide rail 5. Preferably, they are formed by punched and bent tabs of the guide rail 5.
    If during the displacement of the guide rail 5 in one of the displacement directions 6, 7 at the end of the displacement of one of the counter-stop elements 20, 21 starts at the stop damper, the force exerted by the counter-stop element 20, 21 force directly or via the possibly arranged on the stop extension 29 elastomer element 41 transferred to the transmission part 23 and via this on the elastic damping parts 24, 25. The transmission part 23 is in this case in the direction of displacement 6, 7th
    FOLLOW-UP • I Μ ·· ** ff «Mt • I ft I I · · t · · ·
    • · · t | * J shifted, wherein portions of the elastic damping members 24 are stretched and portions of the elastic damping members 24, 25 are compressed. As a result, the stop of the counter-stop element 20, 21 is damped on the stop damper 22. There is also a certain pivoting of the stop extension 29 about a (free) vertical axis, wherein lying between the bead 34 and the vertical web 32 portions of the damping members 24, 25 are compressed or stretched. This also causes a damping.
    From a limit of the force exerted by the counter-stop element 20, 21 on the damper 22 force the transmission member 23 comes to rest on the window 31 in the direction of displacement 6 and 7 displacement limiting edge, which forms an end stop 42,43. When the limit value of the force exerted by the counter-stop element is exceeded, a part of the force exerted on the stopper damper 22 is transmitted directly, ie without transmission via the elastic damping parts 24, 25, to the guide rail 4 on which the stop damper 22 is arranged , 43 can also be used in other ways, eg are formed by a mounted on the guide rail 4 part.
    Below the limit, the transmission part 23 does not cooperate with that of the respective end stop 42, 43, so that no force is transmitted to the end stop 42, 43.
    When the force exerted by the counter stop member 20, 21 on the stopper damper 22 is stopped, the elastic restoring force of the elastic damping members 24, 25 returns the transmission member 23 to the output position.
    In modified forms of training it could also be provided to provide a separate stop damper 22 for each of the displacement corrections 6, 7. This could then interact with a common or a respective counter stop element 20, 21. If a stop damper is effective only in one direction 6 or 7, so would only one end stop 42, 43rd
    NACHGEREIC; IT 14 is required, which limits the displacement of the transmission part 23 in this displacement direction 6 or 7.
    The stop damper 22 could be modified in various ways, for example, having only one elastic damping member 24, 25. Such a design could be provided, for example, if separate stop dampers are provided for the two displacement directions 6, 7. For example, could the stop extension 29 then be connected via a single hook-shaped holding extension 26, 27 with the damping member.
    On the cover 40 of the snap part 35 provided extensions 44, 45, between which the holding web 30 is located, serve for additional support and guidance of the retaining web 30, but could also be omitted.
    The transmission part 23 consists in the embodiment of metal, in particular steel. For example, the transmission member 23 could be made of another rigid material, e.g. Hard plastic. The material of which the transmission part 23 is made is substantially harder than the elastomeric material of which the damping parts 24, 25 are made. This is for example formed by a rubber elastomer, but could also be formed by a different elastomer. Thermoplastic elastomers are also understood in the context of this document as elastomeric materials. Due to the elasticity of the elastomeric material, a compression or elongation results in a force opposing the compression or elongation. Due to the internal friction of the elastomeric material, a change in shape leads to a damping effect.
    The end stops 42, 43 are advantageously made of metal, preferably steel. In the embodiment shown, they are made of the same material as the guide rail 4. The end stops 42, 43 could also be formed of a rigid material other than metal, e.g. a hard plastic.

    The counter-stop elements 20, 21 are advantageously made of metal, in particular steel. In the embodiment shown they are made of the same material as the guide rail 5, to which they are arranged. The counter-abutment elements 20,21 could also be made of a rigid material other than metal, such as a hard plastic.
    The displacement of the central guide rail 4 with respect to the body-mounted guide rail 3 in the pull-out direction corresponding displacement direction 6 is limited by the start of a arranged on the corpus fixed guide rail 3 counter-abutment member 46 arranged on the central guide rail 4 stop damper 47, the stop damper 47 damps the deceleration of the shifted in the direction of displacement 6 middle guide rail 4 at the end of the displacement.
    The counter stop element 46 is formed in the embodiment of an impression in the upper catwalk 17 of the corpus fixed guide rail 3 (which limits the used as a raceway section of the upper catwalk 17). As a result, a projection is formed, which represents the counter-stop element 46. The counter-abutment member 46 could e.g. be formed by a stamped out of the material of the guide rail 3 and bent tabs or by a separate, attached to the guide rail 3 part.
    The stop damper 47 comprises a rigid transmission part 48, which is movably mounted relative to the guide rail 4. For this purpose, the transmission part 48 is mounted pivotably about an axis of rotation 49 on the guide rail 4. The axis of rotation 49 is perpendicular to the direction of displacement 6. In order to achieve a space-saving design, it is preferred that the axis of rotation 49, as shown, is aligned horizontally.
    A formed of an elastomeric material, elastic damping member 50 counteracts a pivoting of the transmission part 48 about the rotation axis 49 when at the start of the counter-stop member 46 to the
    FOLLOW-UP: t I 16 * Φ · · t * · * * «ι t« »« · »· *« * · »»
    Stop damper 47, the transmission part 48 is deflected from its example shown in Fig. 11 starting position. The elastic damping member 50 is supported here between the transmission part 48 and an upper horizontal web 51 of the guide rail 4. The holder of the elastic damping member 50 is carried out in the embodiment by means of holding elements 52, 53, 54 on the transmission part 48, but could also be done on the guide rail 4.
    The transmission part 48 is formed in the illustrated embodiment in the form of a two-armed lever. The first lever arm 63 is pivoted by the counter-stop member 46 when starting and the second lever arm 64 cooperates with the elastic damping member 50. Instead, the transmission part 48 could also be designed as a one-armed lever. A training with more than two lever arms could be provided.
    The lever arm, which cooperates with the counter stop element 46, could also be referred to as a stopper extension.
    Elastomer elements 62 are arranged on the lever arm cooperating with the counter-stop element 46 in order to additionally dampen the impact noise (especially in the case of slight stops). At these elastomeric elements run against the stop member 46 and the end stop 55 described below. At high loads, the elastomer elements 62 can be pressed into recesses, so that at high forces, the counter-stop element 46 and the end stop 55 come directly into contact with the transmission part 48. With the counter-stop element 46 and / or cooperating with the end stop 55 elastomer elements could also be omitted.
    If during the displacement of the guide rail 4 in the direction of displacement 6 at the end of the displacement path, the counter-stop member 46 starts against the stop damper 47, the force exerted by the counter-stop member 46 force on the transmission part 48 directly or via the optionally on
    I NACHGC .----- 17
    Transfer member 48 arranged elastomeric element 62 and transmitted via this to the elastic damping member 50. The transmission part 48 is thereby pivoted about the axis of rotation 49. Here, the elastic damping member 50 is compressed. The stop of the counter-stop element 46 on the stop damper 47 is thereby damped.
    From a limit value of the force exerted by the counter-stop element 46 on the stop damper 47, a further pivoting of the transmission part 48 about the axis of rotation 49 is blocked by an end stop 55. The end stop 55 is formed in the embodiment of an abutment edge of the central guide rail 4, but could also in other ways, e.g. be formed by a mounted on the middle guide rail 4 part. In the exemplary embodiment, the lever arm 63, against which the counter-stop element 46 starts, cooperates with the end stop 55. It could also the lever arm 64, which cooperates with the elastic damping member 50, with the end stop 55 cooperate.
    As a result of the interaction of the transmission part 48 with the end stop 55, when the limit value of the force exerted by the counter-stop element 46 is exceeded, part of the force exerted on the stop damper 47 is transferred directly to the guide rail 4, ie without transmission via the elastic damping part 50.
    When the force exerted by the counter-abutment member 46 on the stopper damper 47 is stopped, the elastic restoring force of the damper member 50 returns the transmission member 48 to the home position.
    Below the limit value, the transmission part 48 does not cooperate with the end stop 55, so that no force is transmitted to it.
    The materials that make up the transmission part 48, the damping part 50, the end stop 55 and the counter-abutment element 46 are the same as before 18 in connection with the transmission part 23, the damping parts 24, 25, the end stops 42, 43 and the counter-stop elements 20 , 21 described.
    In order to dampen the stop of the central guide rail 4 on the corpus fixed guide rail 3 at the end of insertion in the direction of displacement 7, a conventionally trained stop damper 56 is provided in the embodiment. The here mutually come into contact surfaces can be made so large that there is no excessive wear of this stop damper 56. The stop damper 56 is formed by a bent stop extension of the corpus fixed guide rail 3, of which a rubber buffer 57 is held. The arranged on the central guide rail 4 counter-abutment member 58 is disposed on a formed in a known manner adjustable stop unit 59 made of plastic.
    When the stopper unit 59 is displaced from the fixed guide position shown in Fig. 11 opposite to the center guide rail 4 toward the front end thereof (= toward the front roller 8), a lock member is disengaged from the guide rail 4 and Anschiageinheit 59 can be pivoted about the pivot axis 60, so that an Anschfagvorsprung 61 moves upward. The middle guide rail 4 can thereby be pivoted slightly upwards relative to the body-fixed guide rail 3 with its front end, so that the counter-abutment element 46 can be guided past the transmission part 48. Thus, the middle guide rail 4 can be removed in the direction of displacement 6 from the corpus fixed guide rail 3 or in the opposite direction of displacement 7 for mounting the pull-out in the corpusfeste guide rail 3 are used.
    The displacement of the central guide rail 4 in the displacement direction 7 relative to the body-fixed guide rail 3 limiting stop damper could also be formed in an analogous manner as the stop damper 47 or as the stop damper 22.

    A stop damper designed analogously to the stop damper 22 could also be provided in order to limit the displacement of the central guide rail 4 in relation to the body-fixed guide rail 3 in the displacement direction 6. To limit the displacement of both the central guide rail 4 relative to the body-fixed guide rail 3 both in the direction of displacement 6 and in the direction 7, a common, designed in a similar manner as the stop damper 22 stop damper could be provided.
    The displacement of the extendable guide rail 5 with respect to the central guide rail 4 in the direction of displacement 6 and / or in the direction of displacement 7 could also be limited by a stop damper designed in an analogous manner to the stop damper 47.
    The arrangement shown in the embodiment of the stop damper 22,47, 56 and cooperating with these counter-stop elements 20, 21,46, 58 on the guide rails 3, 4, 5 could also be reversed.
    A stop damper with a rotatable about a pivot axis 49 transmission part 48 could also for limiting the displacement of a second guide rail (eg, the middle guide rail 4 or the extendable guide rail 5) against a first guide rail (eg, the corpus fixed guide rail 3 or the middle guide rail 4) both be formed in the direction of displacement 6 of the extension and in the direction of displacement 7 of the insertion. In such a stop damper, the pivoting of the transmission part 48 about the rotational axis 49 in both directions against a restoring force of at least one formed of an elastomeric material, elastic damping member would take place. For both Verschieberungen 6, 7 an end stop would be provided in each case. These could be realized in that the transmission part 48 starts in both directions against a respective end stop. FOLLOW-UP: ΓΓ 20 • · * · # »« * «* * * * ·
    In a stop damper designed to limit displacement in both displacement directions 6, 7, rotation of the transmission part in the same direction of rotation about the axis of rotation could also occur for both displacement directions if the transmission part has its own lever arm for both displacement directions, as will be described below a concrete embodiment will be described.
    The rotatably mounted transmission part! 48 is formed in the embodiment shown L-shaped. A T- or I-shaped training is conceivable and possible.
    Instead of the interaction of the transmission part with the end stop could also be provided for all described forms of training that the respective counter-stop element cooperates with the end stop, as described in the following embodiment. In this case, in a force exceeding the limit value, part of the force exerted by the counter-stop element is transmitted directly from the counter-stop element to the guide rail on which the stop damper is arranged, ie without transfer to the transfer part and the at least one elastic damping part.
    Fig. 21 shows in a highly schematic way a modified embodiment of a stop damper 47 which could be used in place of the stop damper 47 described with reference to Figs. Analogous parts are provided with the same reference numerals. Apart from the differences described below, the training is basically the same as previously described.
    The transmission part 48 is here designed as a one-armed, about the axis of rotation 49 rotatable lever. But it could turn be provided a more than one-armed lever. When starting the counter-stop element 46 to the stop damper 47, the transmission part 48 against the restoring force of
    FOLLOWING 21 ♦ an elastomeric material existing elastic damping member 50 is rotated about the axis of rotation 49. Here, the braking of the guide rail 4 is attenuated at the end of the displacement relative to the guide rail 3. The transmission of the force exerted by the counter-stop element 46 on the stop damper 47 force is again on the Übertragungsstei! 48 to the elastic damping member 50. When a limit of the force exerted by the counter-stop member 46 on the damper 47 force is reached, the transmission member 48 pivots so far about the axis of rotation 49, that the counter-stop member 46 for abutment with one of a portion of the guide rail 4 End stop 55 is coming. A force exerted by the counter-stop element 46, the limit value exceeding force is transmitted directly from the counter-stop element 46 on the end stop 55, that is not transmitted via the transmission part 48 to the elastic damping member 50.
    A further modified embodiment of the invention will be described below with reference to FIG. 22. Analog parts are again provided with the same reference numerals. The modified trained section of the central guide rail 4 with the stop damper 47 disposed thereon is shown in Fig. 22. The remaining part of the middle guide rail 4 is formed unchanged. In the case of the corpus-fixed guide rail 3, the rubber buffer 57 can be dispensed with, so that the body-fixed guide rail 3 only has a bent tab which forms a counter-abutment element 66. Such a counter stop element 66 of the corpus fixed guide rail 3 is shown schematically in FIG. Incidentally, the body-fixed guide rail 3 and the extendable guide rail 5 as shown in FIGS. 1 to 20 are formed.
    The transmission part 48 has an additional lever arm 65 here. At this third lever arm 65, the counter-stop element of the corpus fixed guide rail 3 runs at the end of the displacement when inserting the middle guide rail 4 in the direction of displacement 7. The transmission part 48 is thereby rotated about the rotation axis 49 against the restoring force of the elastic damping part 50. The direction of rotation is the same as when starting the

    Counter stop member 46 to the first lever arm 63. The contact surfaces on the first lever arm 63 for the counter-stop member 46 and the third lever arm 65 for the counter-stop member 66 have in opposite directions, When the limit of the force exerted by the counter-stop member 66 force is exceeded 5, it comes to cooperate the first lever arm 63 with the end stop 55, analogously as previously described in connection with the tarnishing of the counter-stop member 46 to the first lever arm 63.
    On the third lever arm 65, in turn, preferably depressible, 10 elastomeric elements 67 may be arranged.
    An effective at both ends of the displacement stop damper with a pivotable about a rotation Übeitragungsteil could for example also be realized with a two-armed lever, wherein at least one of the two 15 lever arms in addition to cooperating with the associated
    Gegenanschlageiement also cooperates with an elastic damping member made of an elastomeric material.
    An end stop 55 could interact with the second lever arm 64 or the third lever arm 65 instead of the first lever arm 63.
