Definitions

  • the present invention refers to a guide structure for a part which can be extracted from the body of a furniture piece or the like, of the type comprising an extractable guide element adapted to be fixed to the extractable part and a load-bearing guide element adapted to be fixed to the body of the furniture piece .
  • a median element is provided sliding in a differential manner on these elements on both sides of the drawer, where between the guide elements slidable elements or trolleys are arranged which are equipped with spheres and/or rollers supporting the weight of the drawer or extractable furniture piece part.
  • a differential guide fitting of this type is known for example from the European patent EP 0 720 824 Bl, where in order to use section bars of simple form, the median element is composed of two section bars separated with U-shaped section, arranged back-to-back and connected together at their ends through bent flanges .
  • the stability of the drawer or extractable furniture piece part in its completely extracted position depends on the precision of the coupling between the rails and the trolleys slidable thereon, but also on the length of the sections for which the median element remains superimposed (anchored) respectively on the load-bearing element on one side and on the extractable element on the other.
  • Such overlapping length cannot be freely chosen, but depends on the depth of the drawer and on the length of the guides .
  • the overlapping length obtainable with the known guides does not allow ensuring a good stability of the drawer or furniture part in its completely extracted position.
  • the technical task of the present invention is therefore that of making a guide structure for a part which can be extracted from the body of a furniture piece and a related extraction process which allows eliminating the lamented technical drawbacks of the prior art .
  • one object of the invention is that of making a guide structure for a part which can be extracted from the body of a furniture piece and a related extraction process which allows increasing the stability of the guide structure in a simple manner as the extraction of the extractable part proceeds.
  • the stabilisation means comprise at least two parallel median elements, both slidable on the load-bearing element and extractable element in a differential manner from each other.
  • a median element In the completely open position of the drawer, therefore, due to their differential movement, a median element is situated still overlapping for most of its length on the load-bearing element fixed to the furniture piece, while the other median element is situated inserted for most of its length on the extractable element and vice versa for the remaining smaller parts of the respective lengths.
  • the length of the parts of the extractable and fixed elements anchored on the offset median elements is greater than that which would be had with only one median element, consequently increasing the stability of the open drawer and the strength of the guides.
  • the differential movement between the median elements themselves and respectively between these and the fixed and movable elements can occur in any one of the already known modes.
  • the arrangement can be provided for of appropriate stopping stops and driving stops for delimiting the respective movements of the various drawer positions, or tie rods can be adopted between rails and trolleys, or friction elements or mesh elements can be adopted, like gearwheels and racks interacting with the various elements composing the guide.
  • the length of the trolleys situated between the fixed element and each of the median elements is different, as the length of the trolleys situated between each of the median elements and the extractable element is also respectively different, depending on the respective overlapping lengths due to the staggering of the median elements.
  • trolleys of equal length can be provided, prearranging, however, the stops on the guide elements appropriately staggered between them.
  • the stabilisation means comprise a first and at least a second longitudinal element which are telescopically connected together and in turn connected with the load-bearing guide element and with the extractable guide element, so to assume a configuration which confers overall stability to the structure, also in the maximum extraction configuration of the extractable part.
  • Figure 1 shows a perspective view of a guide structure which can be applied on the left part of a furniture piece and a drawer in accordance with a first preferred embodiment of the invention

  • Figures 4a, 4b and 4c schematically illustrate the position of the various elements composing the guide structure of figure 1 in the reverse closing movement of the drawer, starting from the completely open position (figure 4a, corresponding to figure 3c) , up to the closed position (figure 4c, corresponding to figure 3a) , passing for the intermediate position (figure 4b) ;
  • Figure 5 shows a front view of the guide structure of figure
  • Figure 6 shows a front view of a guide structure in accordance with a second preferred embodiment of the invention.
  • Figure 7 shows a perspective view of a guide structure in accordance with a third preferred embodiment of the invention.
  • Figure 8 shows a front view of the guide structure of figure 7.
  • a guide structure having a part (not shown) which can be extracted parallel to an extraction direction (indicated with the reference 100 in figure 1) from the body of a furniture piece (not shown) , of the type comprising an extractable guide element longitudinally parallel to the extraction direction and adapted to be fixed to the extractable part and a load-bearing guide part longitudinally parallel to the extraction direction and adapted to be fixed to the body of the furniture piece.
  • the guide structure advantageously has means for its stabilisation adapted to progressively oppose the progressive increase of the bending moment to which it is subjected due to the weight at least of the extractable part, as the extraction of the extractable part from the body of the furniture piece.
  • the stabilisation means preferably comprise a first and at least a second element sliding parallel to the extraction direction.
  • the guide structure also has means for the differential movement of the first and at least the second slidable element.
  • the first and second slidable element are composed of a first and at least second longitudinal median element slidable along opposite sides of the extractable guide element and load-bearing guide element.
  • the part 1 of a guide structure is clear, consisting of a differential guide fitting attachable on the left part of the furniture piece and drawer (which are not shown) .
  • a corresponding symmetrical part is attached on the right part of the furniture piece.
  • load-bearing guide element 2 fixable to the side of the furniture piece
  • extractable guide element 3 on which the drawer can be coupled, in addition to the first and respectively second offset
  • longitudinal median elements 4 and 5 are evident.
  • FIG 2 illustrated in side view are the components of the fitting of figure 1, separated from each other.
  • a first pair of a first and second trolley 6 and 7 (not visible in figure 1) connect the extractable guide element 3 respectively with the median elements 4 and 5, while a second pair of a third and fourth trolley 8 and 9 respectively connect the same median elements 4 and 5 with the fixed guide element 2.
  • the trolleys are equipped with slidable spheres 10, preferably placed at their ends.
  • the median elements 4 and 5 are of equal length, while the trolleys 6, 7 and 8, 9 of the two pairs are of different length from each other.

  • such movement means comprise, for the extraction step of the extractable part, a first pair of a first and respectively second stop 20 aligned orthogonally to the extraction direction 100, provided on the extractable guide element 3 and adapted to drive the first and respectively second trolley 6 and 7, a second pair of a third and respectively fourth stop 21 and 22 and a third pair of a fifth and respectively sixth stop 23 and 24 respectively provided on the median elements 4 and 5 and adapted to drive the third and respectively fourth trolley 8 and 9, and a fourth pair of a seventh and respectively eighth stop 25 aligned orthogonally to the extraction direction, provided on the load-bearing guide element 2 and adapted to stop the third and respectively fourth trolley 8 and 9 at the complete extraction position of the extractable part .
  • the stops 20 are provided on the end of the extractable element turned towards the interior of the furniture piece. These, during the extraction of the drawer, hit against the internal front parts of the trolleys 6, 7, driving them into their extraction movement. The opposite, external front parts of the trolleys 6, 7, joined at the external ends of the median elements 4, 5, hit against the respective stops 21, 22 placed thereon, driving them into the position seen in figure 3b. Since the trolleys have different lengths, the movement of the median elements 4, 5 occurs in the illustrated differential manner.
  • the movement means comprise other stops for the retraction step of the extractable part.
  • the movement means comprise, for the retraction step of the extractable part, a fifth pair of a ninth and respectively tenth stop 26, 27 provided on the extractable guide 3 and placed at a mutual distance, parallel to the extraction direction 100, equal to the difference of length between the first and second trolley 6 and 7, and a sixth pair of an eleventh and twelfth stop 28, 29 placed on the fixed guide 2 and spaced from each other in a manner corresponding to the stops 26, 27 of the extractable guide element 3.
