    专利说明:

    The present invention relates to a drawer pull-out guide, comprising: a first rail and at least one second rail, which are movably mounted relative to each other, at least one carriage with at least one rolling element, wherein the carriage between the first rail and the second rail via a Track is movably mounted, - at least one limiting element which is arranged on the first rail or on the second rail, wherein the limiting element limits the travel path of the carriage, - arranged on the carriage damping device, which movement of the carriage on impact of the carriage the limiting element attenuates via a Dämpfweg, wherein a maximum Dämpfweg the damping device is predetermined.
    Furthermore, the invention relates to a piece of furniture with a furniture body and with a drawer, which is movably mounted relative to the furniture body via a drawer extension of the type to be described.
    In EP 0 868 866 B1, a drawer pull-out guide with a carcass rail and a movably mounted pull-out rail is shown, wherein a carriage with load-transmitting rolling elements is mounted displaceably between the carcass rail and the pull-out rail. At the rails stops are present, which limit a travel path of the carriage in the longitudinal direction of the rails. The carriages have spring buffers on their front sides, which dampens an impact of the carriage on the stops in the end positions of the carriage.
    The disadvantage of this is that the kinematic energy is absorbed almost exclusively by the carriage when reaching the respective end positions of the pull-out, whereby the carriages are exposed to considerable loads. These loads can lead to deformation or even to a breakage of the carriage, especially if the carriages are designed for reasons of compact design with a small wall thickness made of plastic. An additional burden on the carriage is also given when the drawer extension has a short nominal length, because then the pull-out shortly after opening often comes with a lot of momentum in the fully extended position and thus the spring buffers of the carriage powerful on the attacks of the rails mount up. Even in a case of abuse in which the drawer is catapulted with excessive manual force in the closed position or open position, considerable forces act on the carriage, so there is a risk of damage to the carriage.
    Object of the present invention is to provide a drawer extension of the type mentioned, wherein the risk of damage to the carriage is reduced.
    This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.
    According to the invention, it is thus provided that a stop is arranged on the first rail and that a counterstop is arranged on the second rail, the stop of the first rail and the counterstop of the second rail striking one another at the end of the maximum damping path of the carriage and thus a movement stop the second rail relative to the first rail.
    The present invention is thus based on the basic idea that the carriage is damped when hitting the limiting element initially over the predetermined maximum Dämpfweg the damping device, which abuts when exceeding a predetermined application of force to the carriage of the stop and the counter-stop of the rails together and a further rail movement Stop, so that a further force on the carriage is prevented.
    In this way, the excessive forces are absorbed by the rails of the drawer extension guide, so that the carriage remains untouched by these additional forces. The carriage is thus exposed after completion of the damping stroke of the damping device no additional loads that can lead to deformation or breakage.
    The damping device may be arranged at a front end of the carriage, wherein the damping device according to a first embodiment may have at least one arranged on the carriage spring tongue, which is reversibly bendable or reversibly deformed upon impact of the carriage on the limiting element against a resilient action of the spring tongue. The maximum Dämpfweg is thus determined by a maximum Kompressierweg the spring tongue, without causing the spring tongue, the carriage or another component is damaged.
    According to another embodiment, it can also be provided that the damping device of the carriage has a fluid damper, for example with a piston-cylinder unit, as shown and described in EP 1 475 014 B1. The maximum Dämpfweg is given in this case by the maximum allowable damping stroke of the piston-cylinder unit.
    Since the closing movement of an extendable rail of the drawer pull-out guide is often slowed down by a damped automatic retraction mechanism, a rail stop in the closed position of the drawer pull-out guide is not absolutely necessary. Thus, it may be sufficient if the first rail and the second rail are movably mounted between a closed position and an open position, wherein the stop of the first rail and the counter-stop of the second rail abut each other in the open position and thus a continued extension movement of the second rail in Prevent opening direction.
    A first embodiment of a piece of furniture according to the invention is characterized in that the piece of furniture has a furniture body and a drawer which is movably supported relative to the furniture body via a drawer pull-out guide of the type in question, wherein the first rail has a cabinet rail to be fastened to a furniture carcass and the second Rail one at the
    Drawer-mounted drawer rail, wherein the car is movably mounted between the carcass rail and the drawer rail.
    A second embodiment of a piece of furniture according to the invention is characterized in that the piece of furniture has a furniture body and a drawer which is movably supported relative to the furniture body via a drawer pull-out guide of the type in question, the first rail comprising a cabinet rail fastened to the furniture body and the second rail a Middle rail is which is movably mounted between the carcass rail and a drawer rail fastened to the drawer, wherein the carriage is movably mounted between the carcass rail and the center rail.
    A third embodiment of a piece of furniture according to the invention is characterized in that the piece of furniture has a furniture body and a drawer which is movably supported relative to the furniture body via a drawer pull-out guide of the type in question, the second rail comprising a drawer rail fastened to the drawer and the first rail a Middle rail is which is movably mounted between a carcass rail attached to the cabinet body and the drawer rail, wherein the carriage between the middle rail and the drawer rail is movably mounted.
    Further details and advantages of the present invention will be explained with reference to the following description of the figures. It shows or show:
    1 is a perspective view of a piece of furniture with a furniture body and relatively movably mounted drawers,
    2a, 2b a partially broken drawer pull-out guide in a perspective view and an enlarged detail illustration thereof,
    3a, 3b continued pull-out movements of the second rail with an approaching the boundary element carriage,
    4a-4c, the interaction of the damping device with the
    Limiting element and the interaction of the stop with the counter-stop in time sequences.
    Fig. 1 shows a piece of furniture 1 with a cabinet-shaped furniture body 2, wherein drawers 3 are movably mounted on Schubladenausziehführungen 4 relative to the furniture body 2. The drawers 3 each have a front panel 5, a drawer bottom 6, drawer side walls 7 and a rear wall 8. The drawer extension guides 4 each comprise a rail 9 (carcass rail), which is to be fastened to the furniture carcass 2 via fixing sections 12a, 12b, a second rail 10 (drawer rail) displaceably mounted relative to the rail 9 and connected or to be connected to the drawer side wall 7 , And a first rail 11 (middle rail), which is movably mounted to realize a full extension of the drawer 3 between the rail 9 and the second rail 10. For the sake of simplicity, in the present description the middle rail is referred to as first rail 11 and the drawer rail as second rail 10. Of course, it is also clear that the carcass rail can be regarded as a first rail and the center rail as a second rail.
    Fig. 2a shows a partially broken Schubladenausziehführung 4 in an open position with the furniture body 2 to be fastened rail 9 (carcass rail), between the rail 9 and the second rail 10 an aussverlängernde first rail 11 (middle rail) is slidably mounted. Attached to the rail 9 are attachment portions 12a and 12b through which the drawer extension guide 4 is to be mounted on the furniture body 2.
    FIG. 2b shows the area framed in FIG. 2a in an enlarged view. The attachment portion 12a has a plurality of holes 13 for the passage of screws through which attachment to the furniture body 2 takes place. The second rail 10 is shown partially broken, so that the carriage 16 is mounted therein with rolling elements 17 can be seen. At a front end of the carriage 16, a damping device 18 is arranged, which is formed in the illustrated embodiment as a spring buffer with at least one spring tongue 18a. It is preferably provided that the spring tongue 18a is sprayed together with the carriage 16 from a one-piece plastic part. At a rear end region of the second rail 10, a limiting element 15 is arranged, which limits a travel path of the gondola 16 in the withdrawal direction 19. The limiting element 15 is integrally formed in the figure shown together with the second rail 10 and may be formed as a bent from the second rail 10 tab. The spring tongue 18a is reversibly bendable or reversibly deformable upon impact of the carriage 16 on the limiting element 15 against a resilient action of the spring tongue 18a and dampens in this way, an impact of the carriage 16 on the limiting element 15. Instead of one or more spring tongues 18a can be used as a damping device 18th Also, a linear damper, for example with a piston-cylinder unit, be arranged on or in the carriage 16. At the rear end of the second rail 10, a pin 14 is arranged, which extends at a distance to an upper side of the second rail 10 in a horizontal direction in the longitudinal direction of the second rail 10. This pin 14 engages in mounting position in a in the rear wall 8 (Fig. 1) arranged bore, thus preventing an undesirable change in position of the rear end portion of the drawer 3 relative to the second rail 10th
    FIG. 3 a shows a movement of the second rail 10 in the pull-out direction 19 continued in relation to FIG. 2 b, wherein the spring tongue 18 a of the damping device 18 bears against the limiting element 15. In Fig. 3b, the maximum Dämpfweg 23 (Fig. 4b) of the damping device 18 is reached, wherein the free end of the spring tongue 18a abuts the carriage 16 and thus is maximally deformed or bent. In this position of the carriage 16, a stop 20 of the first rail 11 and a counter-stop 21 of the second rail 10 abut each other and stop movement of the second rail 10 relative to the first rail 11, as shown and described in the following figures.
    4a-4c show the interaction of the damping device 18 of the carriage 16 with the limiting element 15 of the second rail 10 and the interaction of the stop 20 of the second rail 10 with the counter-stop 21 of the first rail 11 in time sequences. The limiting element 15 and the stop 20 are fixedly connected to the second rail 10, while the counter-stop 21 is fixedly connected to the first rail 11 in connection. The second rail 10 is moved in the pull-out direction 19 until the at least one spring tongue 18 of the damping device 18 of the carriage 16 strikes the limiting element 15 of the second rail 10 (FIG. 4 b), the stop 20 projecting transversely from the second rail 10 the counter-stop 21 projecting transversely from the first rail 11 are still spaced apart from each other. By a deflection or deformation of the spring tongue 18a is a movement of the carriage 16 via a predetermined Dämpfweg 23 dampened, namely, until the free end of the spring tongue 18a is deformed by stops on the carriage 16 maximum or bent. Upon reaching the maximum damping stroke of the damping device 18, the abutment 20 of the second rail 10 and the counter-abutment 21 of the first rail 11 abut against each other (FIG. 4c) and thus prevent further movement of the second rail 10 relative to the first rail 11. By the interaction the stop 20 and the counter-stop 21 of the carriage 16 is relieved of additional forces, so that the risk of undesirable deformation or breakage of the carriage 16 is prevented. It can be provided that the interaction of the spring tongue 18a with the limiting element 15 and the interaction of the stop 20 with the counter-stop 21 for a person cause two distinguishable noises. The rail stop formed by the stop 20 and the counter-stop 21 is namely harder than the formed by the damping device 18 and the limiting element 15 carriage stop formed. This can for example be achieved by the stop 20 and the counter-stop 21 are each formed of a metallic material and thus cause an acoustically hard warning sound. Thus, much of the energy is dissipated via these "hard stops" and not over the carriage 16.
    The drawer extension guide 4 also has a positive control 22, by which a movement of the carriage 16 relative to another carriage 16a (which is slidably mounted between the rail 9 to be fastened to the furniture body 2 and the first rail 11) and / or at least one movement of Carriage 16 is controllable relative to the first rail 11 and second rail 10 according to a predetermined movement pattern. In the illustrated embodiment, the positive control 22 comprises a rotatably mounted on the first rail 11 gear, which cooperates on the one hand with a toothing of the upper carriage 16 and on the other hand with a toothing of the lower carriage 16a. Alternatively, the positive control 22 - as known per se - have a friction wheel, which cooperates on the one hand with a first running surface of the rail 9 and on the other hand with a second running surface of the second rail 10.
