Definitions

  • the invention relates to a drawer mounted by means of a roller pull-out guide in the body of a piece of furniture, on the side walls of which in the rear end region inside the body there is at least one castor mounted rotatably about an axis perpendicular to the direction of pulling out and horizontally, which can be attached to the respectively assigned body wall
  • Guide rails are able to roll provided tracks, the guide rails each having at least one track roller rolling on the associated drawer side wall in their outer front end region of the body.
  • Such drawers are known, on the side walls of which tracks for the roller pull-out guide are integrated. Particularly in such drawers, in which the drawers have punched-pressed metal sheet punched and folded sidewalls, it is advisable to run the tracks for the roller provided on the front end of the guide rail on the drawer by a folded from the upper edge of the drawer side wall and to form with a strip of material adjoining it and bent downwards.
  • the disadvantage of such Single roller drawers are that the drawer can only be pulled out of the interior of the cabinet until the rollers provided at the rear end of the drawer side walls abut against the rollers provided at the front end of the body-fixed guide rail. Then the rear part of the drawer is still in the cabinet body and this area is less accessible than drawers with a so-called full extension, ie where the drawer can be pulled out of the body completely.
  • Full extensions generally require the interposition of a further intermediate rail with a Z-shaped cross section and in turn provided with castors.
  • the weight, the technical effort and the costs for such a full extension then increase noticeably.
  • the invention is based on the object of further developing the roller pull-out guide of a drawer by its type in question here with simple and inexpensive means so that the drawer can be pulled completely out of the interior of the body, corresponding to a drawer provided with a full extension.
  • this object is achieved according to the invention in that the rollers which are rotatably mounted on the respectively associated drawer side wall in the end region of the interior of the body are themselves a predetermined distance in the direction of extension between a non-retracted and one over the rear wall of the drawer in Direction to the body rear wall protruding extended position is arranged longitudinally displaceably mounted slide member. Due to the possibility to move the slide into the extended position, which is the rollers on it clearly behind the drawer rear wall, it is possible to pull out the drawer to further extend the length of the slide.
  • the respective slide component expediently has a bearing plate which is arranged in a cutout or a recess in the side wall which is open towards the inside of the body and essentially fills out the cutout or the recess and on which the roller is rotatably mounted and is then on the bearing plate a flat guide slide is attached, which is held in a parallel arrangement in a longitudinally displaceable manner on the side wall, preferably on the outside of the respective side wall facing the associated body wall.
  • At least two guide brackets which are spaced apart from one another in the pull-out direction of the drawer, fit over the guide slide and are fastened to the side wall, can be provided for holding the guide slide.
  • This stop can be formed by the head of a screw with its short shaft screwed into a threaded hole in the guide rail. This has the advantage that after unscrewing this screw forming the stop, the guide slides can be easily removed from the side wall of the drawer by pulling them out of the guide brackets.
  • the guide slide can also have an elongated length that is dimensioned in accordance with its width and depth Bead in the drawer side wall itself, whereby then - for example by short, the side wall remote side of the guide bracket rag - care must be taken to ensure that the guide bracket can not exit at right angles to the direction of pulling out of the bead.
  • Another advantage is an embodiment in which a spring under tension biases directly or indirectly in the slide component, which biases it into the retracted position in which the bearing plate is in the cutout of the side wall.
  • the prestressing force exerted by the spring on the slide component is expediently greater than the frictional forces between the slide component and the components which hold it displaceably in order to keep the extended slide component in the extended position.
  • the drawer is then self-retracting with regard to the extension path additionally provided by the slide component. If, on the other hand, the usual self-retraction is then provided by changing the inclination of the guide rail at its inner end, the drawer is also self-retracting as it approaches the closed position.
  • a latching device can be provided which holds the slide component in the fully extended position, but which is then pushed in by a short pressure when the drawer is pushed in is released on the drawer front panels, whereupon the pretension of the spring acting on the guide slide takes effect and pulls in the slide.
  • the guide rail 14 to be mounted on the associated body wall is of conventional design.
  • the guide rail is designed as a profile rail which is approximately U-shaped in cross-section and can be fastened with its web surface 16 against the associated body wall, the profile legs 18a, 18b of the U-legs which project from the web surface 16 in the direction Step forward to the drawer side wall 12 and form raceways for a roller 20 which is rotatably mounted on the inside end of the drawer side wall.
  • a second roller 24 is then rotatably mounted on the outer front end of the guide rail, enlarged to form a flat fastening flange 22, on which the path of the drawer provided on the drawer side wall 12 rolls.
  • this track is formed by a strip-shaped profile leg 26 angled approximately at right angles from the upper edge of the drawer side wall, from the edge facing away from the side wall, a lower strip-shaped profile leg 28 is folded downward, which on the one hand engages around the roller 24 of the mounting rail on the side facing away from the side and on the other hand stiffens and stabilizes the upper edge of the drawer side wall as a whole.
  • a strip-shaped profile leg 30 in the opposite direction, i.e. folded away from the associated body wall at a right angle, which, in addition to stiffening the side wall 12, also serves to support the drawer bottom (not shown). From this profile leg 30 cut and edged, engaging in a groove or recesses in the drawer bottom tabs 32 are used to fix the drawer bottom on the profile leg 30.
  • In the outer end region of the drawer side wall 12 is about half the height of the side wall part 34 one Connection fitting arranged, to which a second - not shown - fitting part can be fastened, which protrudes from the inner surface of an associated drawer front panel. To the extent described so far, the roller pull-out guide is known.
  • the rotatable mounting of the roller 20 does not take place directly on the drawer side wall 12 ', but on a slide component 38 which is mounted on the drawer side wall 12 so as to be longitudinally displaceable in the pull-out direction of the drawer, namely between one retracted first position, in which the position of the roller 20 corresponds to the position of such rollers on the side wall 12 in the case of conventional roller pull-out guides, and a position shown in FIG. 1 and additionally shown in dash-dotted lines in FIG. 2, in which the roller 20 over the the rear wall of the drawer is pulled out towards the body rear wall.
  • the slide component 38 is composed of a bearing plate 40 and a flat, elongated guide slide 42 which is attached to the bearing plate and which is held on the side wall 12 in a longitudinally displaceable manner in parallel contact.
  • the bearing plate 40 in turn is in the first retracted position in a cutout 44 of the drawer side wall 12 which is open towards the inside of the body and upwards and is dimensioned such that it fills out this cutout in the retracted position of the slide component 38, the cutout can also be replaced by an open to the body back wall open the bearing plate in the retracted position suitably receiving recess. If the bearing plate 40 is arranged offset parallel to the plane of the side wall on the guide slide 42, the cutout 44 or the recess can also be omitted.
  • the flat, elongated guide slide 42 is held against the outside of the side wall 12 facing the body wall, being guided by at least two guide brackets 46a, 46b which are spaced apart from one another in the pull-out direction of the drawer and fit over the guide slide 42 and are fastened to the side wall.
  • a stop in the form of the head of a screw 48 screwed into a threaded bore in the guide slide 42 is provided, which prevents the guide slide 42 and thus the slide component 38 as a whole from being unwantedly pulled out of the guide brackets 46b, 46a .
  • the screw 48 can be unscrewed for assembly and for possible disassembly of the slide component 38.
  • the slide component 38 is biased into the retracted position by an elongated spring 50 connected to the guide slide 42 on the one hand and to the drawer side wall 12 on the other hand, which is under tension.
  • the prestressing of the spring is, however, only so large that it overcomes the friction between the guide slide 42 and the guide brackets 46a, 46b holding it, but does not oppose a pulling force deliberately exerted on the drawer, so that the slide Component provided additional extension path can be realized without the effort of the person pulling out the drawer.
  • a locking device (not shown) that becomes effective in the fully extended position of the slide component between the slide component and the drawer side wall, which prevents a fully extended drawer from underneath after the drawer handle is released the influence of the bias of the spring 50 automatically moves by the amount of displacement of the slide member 38.
  • the latching device can then be unlocked by a short pressure in the direction of insertion when the roller 20 approaches the end stops of the guide rail 14 and the spring 50 then pulls the drawer into the fully closed position.
  • the guide slide 42 can also be realized in another way.
  • the guide for the guide slide 42 can also be integrated into the drawer side wall by molding a suitable bead.
  • Corresponding friction-reducing measures can be taken to reduce the frictional forces occurring between the guide slide 42 and its holder.
  • Appropriate treatment of the surfaces sliding on one another is required here by polishing or coating or by means of anti-friction coatings Plastics or storage of the guide slide in roller bodies.
