Definitions

  • the invention relates to an underfloor pull-out guide for drawers mounted in a cabinet body that can be pulled out and the like, in which the guide rail to be fastened to the body wall and designed as a profiled rail is guided from below into the associated hollow profile rail formed by an open on the underside in the region of Drawer bottom or the underside of the drawer side wall arranged guide rail engages and forms roller tracks for rolling elements held in an elongated cage inside the track rail, which can roll on the roll tracks of the guide rail on the one hand and on the other hand formed in assigned areas of the inner surface of the track rail and so one Allow longitudinal movement of the track relative to the guide rail.
  • Drawer pull-out guides of the type in question here have, due to the large number of rolling elements which are not only spatially offset in the pull-out direction but also at right angles thereto, the shape of balls and / or rollers in addition to their smooth running and the high load-bearing capacity, the additional advantage that they are also in fully extended state have a high degree of transverse stability, so that a drawer stored with them in a cabinet body also in whole extended state in the horizontal transverse direction has no noticeable play.
  • Pull-out guides of this type are therefore increasingly being used for storing drawers in high-quality pieces of furniture.
  • Another advantage is the possibility of producing the hollow profile used for the running rail with a low overall height, so that the running rail - in the so-called "underfloor arrangement" - on the underside of the bottom of a drawer immediately next to the one slightly above the floor Side wall or - if the side walls of the drawer are formed by open hollow profiles made of metal or plastic on the underside - can be arranged within the side wall.
  • This makes it possible to increase the width of the drawer in comparison to roller guides, which have to be arranged between the outside of the side wall of the drawer and the facing inside of the body support wall.
  • the cage holding the rolling elements between the guide and the running rail and fixing them at a mutual distance from one another means that the stroke of the pull-out guide in question is limited to a path that is shorter than the drawer depth of the associated drawer, so that the rear wall of the whole extended drawer is still around the dimension of the cage within the associated cabinet body, ie the pull-out guides of the type in question here are so-called "partial pull-outs". Particularly in the case of low drawers of very great depth, the rear drawer area which is still inside the cabinet body when pulled out is then difficult to see and access.
  • roller pull-out guides it has been proposed to achieve a full extension in that, instead of inserting a further intermediate rail at the rear end of the running rail, an additional running rail part which can be tilted about a vertical or horizontal axis is attached, which when the drawer is pushed in when approaching the whole closed position is pivoted by a positive control so that the horizontal axis upwards or the vertical axis inwards in front of the rear wall of the drawer that the drawer can be inserted further.
  • an additional pull-out path is available which enables the drawer to be fully extended (DE-OS 29 46 113).
  • the invention has for its object to simplify this construction by the hollow profile section is only inevitably guided into the drawer rear wall parallel position when approaching the drawer closed position, while its alignment with the actual running rail in a further extended state by the rolling elements stored cage.
  • a pivoting lever is pivotably articulated about an axis running parallel to the pivot axis of the hollow profile section, in the free end remote from the pivot axis an open mouth slot-like receptacle is provided that at the inside of the body of the cabbage section there is a protruding driver that moves into the receptacle of the pivoting lever when the running rail is moved in the drawer-closing direction as the closing position is approached, and that the pivoting lever in the extending rail position in which the carrier stands outside the receptacle of the pivoting lever, is held in a pivoting end position in which the open mouth of the receptacle is aligned with the insertion path of the driver emerging from the hollow profile section aligned with the running rail, the receptacle of the pivoting lever with respect to its pivot axis to form a Lever arm is offset such that the driver moving into the receptacle pivots the pivot lever in the sense
  • the pivot lever only interacts with the driver provided on the hollow profile section in the last phase of the drawer insertion process when the driver enters the open mouth of the receptacle.
  • the hollow profile section and the pivot lever then interact in the manner desired in the manner of a toggle lever or articulated joint.
  • the pivot axis of the hollow profile sections on the running rail can run either vertically or horizontally at right angles to the direction of displacement of the running rail on the guide rail, so that the respective hollow profile section when closing the drawer either in a horizontal plane in the direction of the opposite drawer side wall or in a vertical plane is pivoted upwards in front of the drawer rear wall.
  • the invention provides that the pivot lever is biased by a spring in the first pivot end position in which the open mouth of its receptacle is aligned with the insertion path of the driver.
  • one end of a spring under tension can act on the hollow profile section on the one hand and the running rail on the other hand such that the hollow profile section in the first pivot position in the sense of pivoting into the first pivot position and in a somewhat opposite direction in the direction of the second drawer rear wall parallel pivot position deflected state in the sense of pivoting into the second pivot position.
  • the arrangement of the spring is thus such that the hollow profile section is additionally acted upon in the direction of the second pivoting position in the state deflected only slightly with respect to the aligned position with the running rail.
  • the arrangement of the spring on the hollow profile section can, moreover, take place in such a way that the bias of the spring acting on the hollow profile section standing in the first swivel end position is relatively low or approaches the value 0, since the hollow profile section is extended by the guide rail when the running rail is in the extended state is locked in the aligned position to the running rail.
  • the magnitude of the bias of the spring acting on the hollow profile section on the one hand and on the running rail on the other hand is dimensioned such that the spring generated in the direction of a pivoting of the Hollow profile section in the direction of the second pivot position is greater than the torque generated by the spring biasing the pivot lever into the first pivot end position.
  • the underfloor pull-out guide shown in the drawings designated in its entirety by 10, has a guide rail 12 which is folded from sheet metal to form a channel-shaped profile and whose one vertical profile leg 14 can be fastened to the inner surface of the side wall 16 of a cabinet body, preferably by screws 18. their Threaded shafts are screwed into the side wall 16 through fastening bores 20 in the profile leg 14. From the lower edge of the profile leg 14 an elongated strip-shaped web section 22 is bent approximately at right angles, from the edge facing away from the profile leg 14 a further profile leg 24 is bent upwards at right angles. The height of this profile leg 24, measured in the vertical direction, is significantly less than the height of the profile leg 14.
  • the running rail 26 which is designed as a hollow profile rail with an approximately inverted U-shaped cross section, is mounted in a longitudinally displaceable manner on the rolling elements and, in the present case, for mounting on the underside of the bottom of a drawer (not shown) directly next to the associated drawer which projects downward from the drawer bottom. Sidewall is determined.
  • the running rail can also be inserted into the open underside of this frame.
  • the pull-out guide matches known pull-out guides of the same type.
  • a hollow profile section 30 is articulated about an axis A which is perpendicular to the drawer insertion direction and perpendicular.
  • This hollow profile section 30 has a cross section which corresponds to the hollow profile forming the running rail 26.
  • the articulation of the hollow profile section 30 at the end of the running rail inside the body takes place in such a way that the latter Hollow profile section between the two end positions shown in FIG. 2, namely a first end position aligned with the end of the running rail 26 - shown in solid lines - and a second end position which can be pivoted about 90 ° in a horizontal plane, which is shown in dash-dot lines in FIG. 2 is.
  • the hollow profile section 14 Since the hollow profile section 14 is attached to the end of the running rail 26 which grips under the drawer over its entire length, in the first end position it still projects in full length over the rear wall 28 of the drawer (not shown).
  • the pivot position of the hollow profile section 30 in the second position shown in dash-dotted lines is controlled in the manner described below so that it is held in the first end position over the largest part of the insertion or extension path of an associated drawer, in which therefore also the Rolling cage at least partially can pass from the running rail 26 into the hollow profile section 30 - and vice versa. Only when the drawer approaches the rear wall 28 of the associated cabinet body to such an extent that the free end of the hollow profile section 30 threatens to hit the rear wall 28, is the hollow profile section 30 pivoted away from the adjacent side wall 16 into the second end position.
  • a pivot lever 32 is pivoted on the web section 22 about a vertical axis a, which in its first - shown in full line in FIG.
  • the open mouth is oriented in the first swivel end position of the swivel lever 32 to the driver 34 so that this moves into the mouth and then in when the insert movement of a drawer and thus the running rail 26 and the hollow profile section 30 in the direction of the body rear wall 28 System comes to the associated limit of the receptacle 36.
  • the driver 34 attempts to move the pivoting lever 32 in the direction of the drawer rear wall 28.
  • the pivot lever 32 is pivotally mounted about the axis a at the rear-side end of the web section 22, the pivot lever can only deflect in the sense of a pivoting movement — directed counterclockwise in FIG. 2.
  • the driver 34 is carried along by the opposite boundary edge of the receptacle 36 in the sense of a pivoting of the hollow profile section 30 in a clockwise direction and the desired reversal of the hollow profile section 30 originally aligned with the running rail 26 takes place into the essentially rear wall parallel - shown in dash-dot lines in FIG. 2 - second end position.
  • leg spring 38 By a spring shown in Fig. 2 as leg spring 38, one leg 38a is held on the pivot lever 32 and the other pivot lever 38b on the web surface 22 of the guide rail 12, the pivot lever 32 is biased into the first pivot end position so that it Automatically takes position even when the drawer is pulled out of the cabinet body so far, that the driver 34 has come out of the receptacle 36.
  • leg spring 38 When inserting the pivot lever is then pivoted after the entry of the driver 34 into the receptacle 36 against the action of the leg spring 38.
  • the pretension of the leg spring 38 increases and tries to return the pivot lever 32 to the first pivot end position. It could then occur with a sufficiently high preload that the pivot lever tries via the driver 34 and thus the hollow profile section 30 to push the drawer out of the interior of the body, which is of course undesirable.
  • the drawer be held in the fully retracted end position by a suitably designed device, which in the simplest case could be brought about by a corresponding latching device or a magnetic catch.
  • This automatic closing device is brought about by a spring, in the case shown, which is designed as a helical spring 40 under tension, one end of which is hooked onto a side bracket 42 on the inside of the body of the running rail 26 and the other end of which is hooked onto a similar bracket 44 on the hollow profile section.
  • the arrangement of the spring via the brackets on the running rail 26 or the hollow profile section 30 is such that the longitudinal central axis of the helical spring 40 in the first pivoting position of the hollow profile section 30 is offset somewhat to the side wall 16 in relation to the pivot axis A.
  • the helical spring 40 in the first swivel position of the hollow profile section generates this moment holding in the first end position aligned with the running rail 26.
  • the hollow profile section 30 is pivoted clockwise by the pivot lever 32 when entering the mouth of the receptacle 36, the longitudinal central axis of the coil spring 40 shifts into a position in which it passes over the pivot axis A and then on the opposite side of the side facing away from the side wall Swivel axis takes effect. This then results in a reversal of the direction of the moment acting on the hollow profile section 30, i.e. the hollow profile section 30 is pivoted in the sense of its pivoting into the second end position parallel to the rear wall.
  • the rolling elements transferring the weight of the drawer in the retracted state via the running rail 26 to the guide rail 12, which are arranged between the inside of the web surface of the running rail and the upwardly facing running track of the guide rail, are designed as rollers which are at right angles to the direction of displacement
  • Running rail horizontally extending axes are stored in the associated cage, it is expedient to align the running rail 26 and the hollow profile section 30 between the then adjacent one another when the running rail 26 is aligned rear end edges of the running rail and the front end edges of the hollow profile section formed parting plane T not to run perpendicular to the running rail displacement direction, but - in plan view - offset at an angle to this, so that the rollers 20 roll through the parting plane at an angle, which leads to a smooth, smooth transition Rolls 20 from the rail 26 in the hollow section section 30 - and vice versa - leads, which is not noticeable in the form of stalls or rattling noises.
  • the hollow profile section 30 providing the additional pull-out path can also be articulated on the running rail 26 so as to be pivotable about a horizontal axis A running at right angles to the drawer pull-out direction, in which case the parallel pivot axis a of the pivot lever must also run horizontally and offset in height from the axis A. .
