Definitions

  • the invention relates to a drawer pull-out device with a fixed to the furniture outer rail, a laterally attached to the drawer slide rail and a central rail, wherein for synchronism control on the inner surfaces of the outer rail and the slide rail extending over their entire length are provided racks which engages on both sides of a toothed wheel mounted in the central rail, and wherein stops are provided to limit the distance of the pull-out.
  • Such a device is already known from DE-GM 78 16 727.
  • Such pull-out devices are widely used for smooth and low-wear guidance of drawers in furniture. Their telescopic function allows the drawer to be pulled out of the piece of furniture in a fully accessible manner.
  • the middle rail consists of two mirror-symmetrical halves, which are assembled into a box-shaped structure, namely the two halves consist of metal rails, which are profiled in a special way and connected to each other in places with the help of hollow rivets.
  • the hollow rivets must be provided in the central area of these profiled metal rails. For this reason, two laterally offset toothed racks are provided both on the body rail and on the push rail, into which two toothed wheels also engage accordingly.
  • a total of sixteen rollers are rotatably mounted in the hollow chambers of the central rail, which run in guide grooves of the carcass rail and the push rail which are triangular in cross section.
  • the known device still results in a relatively high outlay, which can be seen in the complicated structure of the center rail and the required four racks.
  • the total of sixteen rollers have to be stored in order to ensure that the rails roll together.
  • this roller guide is not only very complex, but above all unsafe, because even with a slight pulling of the drawer, the rollers jump out of the triangular guide grooves and question its further usability. The result is often damage or destruction of the drawer puller.
  • From CH-PS 494 005 is also a complete Traction device known, in which the longitudinal edges of the outer rail and the push rail are U-shaped, such that the free legs of the U-shaped edges engage behind the longitudinal edges of strip-like projections of the solid middle rail.
  • this full extension device no synchronization control is provided.
  • the guide rails arranged on both sides for example of a storage plate, are moved differently when the storage plate is pulled out and pushed back in, so that, as practice has confirmed, canting and one-sided inhibitions can occur.
  • the assembly of the guide rails which at first glance seem simple, is difficult. This is primarily due to the special design of the limit stops to limit travel using special bolts and the pieces used in the longitudinal grooves.
  • the invention has for its object to provide a drawer pull-out device, which is once very simple in construction, takes up a small width between furniture and drawer and which ultimately results in a fail-safe, low-noise and low-wear guidance while maintaining a synchronous control, also when the drawer is pulled out or pushed in at an angle.
  • the outer rail and push rail each have a toothed rack in the central region of their inner surfaces, into which the only gearwheel mounted in the central region of the central rail engages, that the two longitudinal edges of the Outer rail and the longitudinal edges of the slide rail are U-shaped, such that the free legs of the U-shaped edges are directed inwards at a distance and parallel to the inner rail surfaces, that the central rail is designed as a solid, one-piece body, the longitudinal edges of which have strip-like projections which extend into the U-shaped edges of the outer rail and the slide rail protrude so that the stops for limiting the extension of the pull-out are formed by two bolts located in the outer rail and the slide rail, which protrude from the inner surfaces of the outer and slide rails and engage in two longitudinal grooves of the middle rail so that the grooves end at a small distance from the end faces of the middle rail, and that the outer rail is provided with pins which protrude outward beyond the
  • the exemplary embodiment of the drawer pull-out device according to the invention shown in FIGS. 1 to 6 has an outer rail 1 which is fastened to the piece of furniture 44 (FIG. 5) by means of preferably four pins 15, 16, 17 and 18. It is essential that the pins 15 to 18, which are expediently formed from solid material in one piece with the outer rail 1, are arranged on claws 11, 12, 13 and 14 projecting outwards beyond the longitudinal edges of the outer rail.
  • This particular type of fastening of the outer rail 1 to the piece of furniture 44 results in a particularly flexurally secure holder, because the pins lying far outside produce a moment opposing a bend in relation to the middle bending line of the outer rail.
  • Another significant advantage of the arrangement of the pins 15 to 18 on the external claws 11 to 14 is that when using the drawer pull-out device these claws are freely accessible, so that the pin can easily knock into the holes 46 and 47 provided in the piece of furniture 44 without running the risk that the drawer pull-out device itself will be damaged at any point on the rails by the hammering.
  • the drawer pull-out device furthermore has a drawer rail 2 which, with the exception of the claws and pins explained, is formed symmetrically to the outer rail 1.
  • This slide rail 2 is, as illustrated in FIG. 5, inserted and held in a drawer groove 49 or groove with a rectangular cross section.
  • the hollow pin 25 is arranged at approximately the same distance from the one end of the push rail as the pins 17, 18 of the outer rail 1.
  • longitudinal grooves 3, 4 are provided in the outer rail 1, which extend almost over the entire length of the rail. Furthermore, longitudinal grooves 5, 6 and 7, 8 are provided, which, however, are interrupted in the central region of the outer rail by a solid rail part, so that metal bolts 9, 10 are used here, which act as stops in connection with the grooves 29, 30 serve to limit the extension on both sides.
  • the push rail 2 is also provided with longitudinal grooves 19, 20 and interrupted longitudinal grooves 21, 22 and 23, 24. The latter again receive an interruption for a material reinforcement in the region of the hollow pin 25.
  • the push rail also has bolts 26, 27 in the central region as stops for the pull-out limitation on both sides.
  • both the outer rail 1 and the push rail 2 each have a toothed rack 33 or 34 in their central region of their inner surfaces, which extend over the entire length of the outer rail and the push rail.
  • the racks 33, 34 are made in one piece from the same material as the rails, so they are incorporated into the material of the rails.
  • the entire drawer pull-out device with all the parts described and explained below is preferably made of a tough, hard plastic, with the exception of the bolts 9, 10 and 26, 27, which can also be made of metal.
  • the drawer pull-out device has a middle rail 28 between the outer rail and the push rail.
  • the middle rail 28 has two longitudinal ends on both sides lying after the outer rail and after the push rail Grooves 29, 30 on, which end with semi-cylindrical stop surfaces 31, 32 on both sides shortly before the end faces of the middle rail 28, so that the bolts 9, 10 and 26, 27 strike against these stop surfaces 31, 32 when pulling out in one direction or the other prevent another move.
  • the two longitudinal edges 40, 41 of the outer rail 1 are U-shaped in accordance with FIG. 5, such that the free legs of these U-shaped edges are directed inwards at a distance and parallel to the inner surfaces of the rails.
  • the longitudinal edges 42 and 43 of the push rail also have a corresponding design.
  • the middle rail 28 is designed as a solid, one-piece body, the longitudinal edges of which have strip-like projections 50 which protrude into the U-shaped edges 40 to 43 of the outer rail 1 and the push rail 2 in a slidable manner.
  • the middle rail 28 still has a narrow, substantially rectangular recess 36 in the center, in which a gear wheel is rotatably arranged by means of an axis of rotation 35, in such a way that it simultaneously engages in the two racks 33 and 34 of the outer rail 1 and inner rail 2 and thereby ensures a synchronous control in the sense that when the pull-out device is pulled out or pushed back in, the middle rail is moved relative to the outer rail by the same distance as the push rail relative to the middle rail.
  • the manufacture of the drawer pull-out device explained above is relatively simple, namely that the outer rail 1, the push rail 2 and the central rail 8 and finally the gearwheel 37 with axis of rotation 35 are manufactured individually.
  • the pull-out device therefore consists of very few individual parts.
  • the gear 37 with the axis of rotation 35 is inserted into the recess 36 and the outer rail 1 and push rail 2 are pushed onto the middle rail 28 from two opposite ends or end faces thereof, so that the edges 40 to 43 into the slot guides 38, 39 of the middle rail intervention. It is then only necessary, for example, to insert or press in the bolts 9, 10 and 26, 27 in the central positions according to FIGS. 1 and 3 in order to hold all parts of the drawer pulling device together captively.
  • the pull-out device is fastened between the piece of furniture and the drawer in such a way that first the outer rail 1 with the claws 11 to 14 and the associated pins 15 to 18 are hammered into the prepared bores 46, 47 of the piece of furniture, with even greater holding security due to the circumferential small ring beads on the pins can be achieved.
  • the drawer 45 with its drawer groove 49 can then be pushed onto the drawer rail. While temporarily pulling the pull-out device slightly outwards, the drawer 45 can be pushed until the hollow pin 45 faces a prepared bore 48.
