Definitions

  • the invention relates to a synchronous guide of a thrust element mounted in a furniture body according to the preamble of claim 1.
  • synchronous guides are used, which are generically designed as a rack and pinion gear, wherein on two opposite sides of the cabinet in each case a rack is attached, with an associated , arranged in the rear region of the thrust element gear meshes.
  • a synchronous rolling of the gears is effected by a coupling rod, at the end the gears are secured against rotation, so that the movement of the one gear is synchronously transmitted to the other gear, wherein the actual rotational movement of the gears from the linear relative movement of the thrust element to the racks when moving the thrust element results.
  • a generic synchronous guide is from the EP 0 512 615 A1 known.
  • the racks of this synchronous guide are each rigidly connected to a body-side guide rail, in which a running rail of the thrust element is mounted.
  • a special stress of a synchronous guide is present when they are used in a so-called pharmacist extract, in which the pusher element corresponds to the vertical height ago a tall cabinet and particularly high weight loads occur.
  • the invention has for its object to further develop a synchronous guide of the generic type so that their reliability is improved with structurally simplest means.
  • track lock now ensures that in addition to the functional movement no relative movement between the gear and the rack is possible, both in the radial, i. in the use position vertical direction as well as in the axial direction, based on the central axis of the gear or the coupling rod.
  • the invention can be realized by different nevertheless simple constructive measures.
  • the respective gear wheel, but preferably the rack can be stored so to speak, floating.
  • the rack is formed, for example, as a cantilever and in the remote from the insertion opening rear portion of the body side or the body rear wall.
  • the rack Since the rack is usually made of an elastic material, it has sufficient mobility for a tolerance-induced deflection, in which case the gear is fixedly positioned on the thrust element.
  • the track safety device is designed as a bow-shaped securing element that covers the toothed rack on the side facing away from the toothed wheel, that is, facing away from the toothing, at least in places, as well as on the side facing the carcass side.
  • the rack may be formed as a prefabricated part, which is shortened according to the required length dimension and inserted into a trained as a separate part holder with which the rack is fixed to the furniture body.
  • This assembly of the rack as it were by the meter allows not only an extremely cost-effective production and storage, but also a subsequent equipment of a piece of furniture with a synchronous guide, whereby the gear storage or attachment can be done on the pusher subsequently.
  • a holder is provided which forms a bearing for the rotatable coupling rod and on which the track lock is attached. With the thrust element, the holder can then be screwed.
  • the teeth of the two racks are arranged on the opposite sides, wherein the gears are axially parallel.
  • the gear axes are vertical, as well as the coupling rods, with each of which two opposing gears are connected for synchronous rolling, including the gears are of course secured against rotation on the coupling rod.
  • the two toothed racks assigned to a body side and forming a pair are guided in the securing element.
  • This fuse element can be attached as a separate component directly to the back of the thrust element or on its side. It is also conceivable to form the securing element integrally with bearing blocks, which serve as a pivot bearing for the coupling rods.
  • the securing element can also be locked to the bearing blocks.
  • An advantage of the synchronous guide according to the invention is that the lowering of the sliding element is reduced from the currently accepted and permissible 4% to 0.2 to 1%.
  • the invention is also characterized by the fact that it can be realized with little constructive and production-technical effort.
  • the racks which can be made in pairs in one piece, usually consist of an elastic material, whereby a sufficient mobility for a tolerance-induced deflection is possible, which is also ensured by appropriate clearance within the leadership of the fuse element.
  • Both the pair forming racks as well as the other components may be made of plastic, however, the coupling rods for the transmission of the Torques are suitably made of metal. In principle, however, it is also conceivable to produce the bearing blocks as well as the securing element and the gears of another suitable material, for example of light metal.
  • the respective rack pair may also be formed as a prefabricated part, which is shortened according to a required length measure and plugged into the separate holder with which the rack pair is fixed to the furniture body.
  • a thrust element 4 is shown mounted in a furniture body 1, said thrust element 4, which is shown in the example only as a frame, a drawer, a register extract or the like may be.
  • FIG. 1 the thrust element is shown in a pushed into the furniture body 1 position while the FIG. 2 an extended position reflects.
  • guide rails 5 are fixed to the opposite sides of the cabinet, which correspond to rails of the thrust element 4.
  • a synchronous guide 6 is provided for a uniform extension of the thrust element 4, in particular to prevent tilting when pulling out.
  • This consists of two racks 7, one of which is associated with a body side 2 and which are stationary relative to the furniture body 1.
  • each rack 7 engages a gear 8, which is fixedly attached to the thrust element 4 by means of a fixed to the rear wall of the carcase 3 back of the thrust element 4 bracket 13.
  • each rack 7 is mounted as a cantilever and secured by a holder 10 to the rear wall 3 of the furniture body 1.
  • the rack 7 can be deflected to a certain extent both in the horizontal and in the vertical direction, ie in both transverse axes to the longitudinal extent.
  • a track lock 9 corresponding to the toothed rack is arranged on the pushing element 4 in the connection region of the toothed wheels.
  • the track lock 9 has two side guides 12, 16, between which the Rack 7 is arranged, wherein between the side guides 12, 16 and the rack 7 a certain amount of play is provided so that the side guides 12, 16 which cover the rack 7 side, are predominantly non-contact in a sliding movement of the thrust element 4 relative to the rack 7 ,
  • each hinged extensions 11 At the free end of the racks 7 are each hinged extensions 11, with which in a known manner an overdraw is possible in which the thrust element 4 is brought out in the extended position on the furniture body 1.
  • FIGS. 7 and 8th is another embodiment of the synchronous guide is shown, in which the toothing opposite longitudinal side of the rack 7 has a longitudinal groove 18 into which the support strip 15 engages quasi as a guide element, whereby the lateral fixation of the rack 7 relative to the gear 8 is ensured.
  • FIGS. 9 to 11 show in different views the connection of the rack 7 on the holder 10th
  • the claw 20 on the toothing of the rack 7 side facing a counter-toothing which corresponds to the toothing of the rack 7.
  • a projection 19 is integrally formed on which rests the rack 7 with its associated edge and is secured laterally.
  • FIG. 12 is shown as a further example of a piece of furniture in the form of a tall unit consisting of the furniture body 1 and the sliding element 4 slidably mounted therein, in each case racks 7 as part of the opposing, the top and bottom of the furniture body 1 forming carcass sides the synchronizer guide 6 are arranged, in which the gears 8 ( FIG. 16 ) engage, which are fixed to the rear wall 3 of the thrust element 4.
  • the gears 8 are rotatably mounted in bearing blocks 21 which are fixedly connected to the rear wall 3 and in which two opposing gears 8 interconnecting coupling rods 14 are guided, at each end a gear 8 is held against rotation.
  • FIG. 13 While in the FIG. 13 the furniture body 1 in isolation with connected racks 7 and associated, but separated from the thrust element 4 bearing blocks 21 is shown, the FIG. 14 the rear side of the push element 4, with racks 7 detached from the furniture body 2.
  • the upper and lower sides of the thrust element 1 forming side parts 24 are each provided with a groove 25 extending in the direction of displacement, in which the associated racks 7 dip.
  • the teeth 23 of the two-paired racks 7 are arranged on the opposite sides in such a way that they are held rigidly to each other in the radial direction, ie transversely to the longitudinal extent, which can be realized in different ways, for example by a one-piece Forming the racks 7 or by direct contact of the backs to each other or by an intermediate element.
  • the racks 7 are quasi clamped by the fixedly positioned gears 8 and are thus secured against deflection in this direction.
  • a backup against a deflection of the racks 7 in the direction transverse thereto is carried by the side guide 12, which is connected to the bearing blocks 21.
  • This lateral guide 12 has a portal-like opening with upper and lower boundary surfaces 26 (FIG. FIG. 15 ), which form the said track lock for the racks 7.
  • the side guide 12 has two parallel and spaced apart guide plates 27 which project into the groove 25 and form a Auslenkbegrenzung for the paired racks 7 in the direction of the gears 8.
  • FIG. 18 is hinged to the pair of racks 7, an extension 28, also of course on the opposite pair, not shown Racks 7.
  • an over extension is possible with the extensions 28, in which the thrust element 4 is led out in the extended position on the furniture body 1.
  • This is bolted to a base plate 29 with the rear wall 3 and has for receiving the rack pair two opposing projecting tooth segments 22, in which the rack pair is inserted from above.
