Definitions

  • the present invention relates to a device for guiding and translating along a longitudinal axis A of a mobile element, such as a drawer or a basket of household appliances, between two fixed vertical walls comprising at least two movable supports integral with the movable element disposed on either side thereof and two elongated sliders in the direction of movement articulated with the movable supports, each slider having an upper edge adapted to move on at least one fixed support secured to the corresponding fixed wall in a translation movement along the axis A.
  • Such a device is described for example in the application for Patent EP 0 994 309.
  • the device described proposes to make a system for guiding and translating an oven plate.
  • rails are integral with the movable element and come fit respectively on a fixed support secured to the wall fixed. Movement is facilitated by the presence of a material sliding.
  • Such a system has the following constraints. It is necessary to have a running game to ensure the proper sliding of the mobile support relative to the fixed support at the level of contact surfaces.
  • the operating set must be sufficient to limit the risk of jamming at the level of the guiding system and allow fluid movement but it does not take not that the operating game is too important otherwise it causes deformation causing an unpleasant visual impression for the user: the moving element leans down in position exit. Besides the unpleasant impression of rough guidance and imprecise, there may be security problems if, mobile leaning too much, its contents just fall or fall on the user.
  • the object of the invention is to obtain the minimum necessary clearance for functioning while at the same time offsetting the games inherent in construction.
  • the invention thus facilitates the realization of guidance in translation while ensuring better ergonomics and better security for the user.
  • each of the sliders also comprises means for pivoting about the axis A and the lower edge of the slider comprises an articulation with the movable support allowing at least one pivot about a parallel axis B to the axis A. Thanks to the joint presence of the two joints at the axes A and B , and on both sides of the movable element, the building sets are absorbed. Thus the games needed for proper operation are located at the contact between the fixed and movable supports and the slide and are no longer disturbed by construction games. It will be noted that the result on the moving element is a slight variation of its height which is in no way prejudicial.
  • each slider has a hook-shaped section adapted to be positioned on a bearing surface of the fixed support whose section is of complementary shape to that of said hook and constitute the pivoting means. around the axis A.
  • a profile is obtained facilitating the rotation of the slider on the fixed support and thus a facilitated movement.
  • the system can slide both on the upper and lower edges of the slider and allow, by extension, the extreme output of the movable support from its housing.
  • This embodiment is obtained by allowing in addition to the rotation already mentioned a translation along the axis B. This feature is particularly interesting in the case of the application of the invention to a dishwasher.
  • a movable member 4 which may be, for example, a drawer, a dishwasher basket and which is movable between the vertical walls 9 of an enclosure by means of a guiding device comprising two symmetrical parts.
  • the movable supports 3 and their connection constitute the two symmetrical parts of the guiding and translation device and are simply shown schematically and explained in the following figures.
  • This device for guiding and translating along a longitudinal axis A of a movable element 4 between two fixed vertical walls 9 comprises at least two movable supports 3 integral with the movable element 4 arranged on either side thereof and two sliders 2, of elongate shape in the direction of movement, articulated respectively with the movable supports 3, these sliders 2 each having an upper edge 5 adapted to move on at least one fixed support 1 secured to the corresponding fixed wall 9 in a translation movement along the axis A.
  • FIGS. 2 and 2 ' show a single part of the device in which the fixed support 1 whose face 1' is intended to be fixed on the wall 9 of the enclosure receives the upper edge 5 of the slider 2.
  • the lower edge 5 'of said slider is engaged in the movable support 3 integral with the movable element 4.
  • the slider 2 can perform a translation along a substantially horizontal axis A relative to the fixed support 1.
  • the movable support 3, integral with the movable element can also follow a translation along an axis B , parallel to the axis A , with respect to the slider 2.
  • the first function of this invention namely the translational movement of the mobile element 4 relative to the fixed walls 9 is thus provided by this means.
  • the upper edge 5 of each of the sliders 2 also comprises means for pivoting about the axis A and the lower edge 5 'of the slider comprises an articulation with the movable support 3 allowing at least one pivoting around the axis. an axis B parallel to the axis A.
  • the upper edge 5 of the slider is in hook-shaped section adapted to be positioned on a bearing surface 8 of said fixed support 1 whose section is of complementary shape to that of said hook and constitute the means of pivoting about the axis A.
  • the fixed support 1 has a open housing 6 of arcuate shape complementary to the hook shape of the upper edge 5 of the slider 2, the lower wall of the housing 6 forming the bearing surface 8 and the upper wall forming the abutment 7, said housing 6 having an extent greater than the length of the hook.
  • the building set J c is the lowest possible (min).
  • the hook-shaped edges 5 and 5 'of the slider 2 are released at the maximum of their permitted rotation in the recesses 6 and 6' respectively of the fixed supports 1 and mobile 3.
  • the fixed supports 1 and mobile 3 are at closer and only a sliding game is maintained between these two parts so that the slider 2 can continue to slide.
  • This position is defined by the geometric shape of the supports 1 and 3 and by the minimum clearance that the designer of such a device is ready to accept.
  • the building set J c is the highest possible (max).
  • the hook-shaped edges 5 and 5 'of the slider 2 are entered at the maximum of their allowed rotation in the recesses 6 and 6' respectively of the fixed supports 1 and mobile 3. This movement is allowed since said recesses 6 and 6 'have a greater than the length of the hooks 5 and 5 '.
  • This movement is achieved through the ability of the slider to rotate around the axes A and B.
  • the substantially arcuate shape of the housing 6 and 6 'allows this rotation.
  • the hook shape given to the upper edge 5 of the slider 2 corresponds to a bearing 8 whose section is of complementary shape and which is integral with the fixed support 1 which constitutes one of the faces of the housing 6 and the bearing surface 2.
  • the housing 6 consists only of this bearing 8, the abutment 7 does not exist.
  • the mobile support 3 rests on the slider 2 via a bearing surface 8 'which constitutes one of the faces of the housing 6' and the bearing surface of the mobile support 3 on the slider 2.
  • the upper portion 7 of the housing 6 as shown in Figures 3 and 4 provides a stop preventing tilting of the movable member 4 along an axis orthogonal to the axis A.
  • the lower portion 7 'of the housing 6' as shown in Figures 3 and 4 allows for a stop preventing the tilting of the movable member 4 along an axis orthogonal to the axis B. It is also conceivable that this stop 7 or 7 'is not formed by the support 1 or 3 itself but by an additional piece.
  • An advantageous embodiment of the invention uses identical parts for the mobile supports 3 and fixed 1. This mode of realization is very economical and can be adopted in achievements where we look for a low cost price.
  • FIG. 2 shows with the same references a another advantageous and economical embodiment of the invention which uses, on each of the vertical walls 9, at least two supports fixed 1 and two movable supports 3 of shorter length and spaced apart to the maximum possible of each other in order to limit the amount of necessary material.
  • Figures 2 to 4 show a preferred embodiment of the invention, where the two supports, the fixed 1 and the mobile 3 are adapted to receive an edge of the slider 2 in the form of a hook 5 and 5 '.
  • the means the pivoting around the axis A and the articulation around the axis B be a simple hinge or ball joint allowing a rotation according to axis A or B.
  • the advantage of designing the two joints according to the invention is to obtain a telescopic movement that is all about is significant in appliances.
  • Figures 2 to 4 present the invention in the case where the slider 2 consists of a section whose section of the slider 2 is in the shape of "S".
  • the advantage of this form is can use identical and inexpensive parts for mobile 3 and fixed 1 supports, but that would not change anything at the invention if the hook shapes 5 and 5 'were disposed of so that they would form a "C".
  • the "C" shape it is less obvious to have identical and therefore economical parts for the fixed supports 1 and mobile 3.
  • Another form that can be envisaged for the section of the slider would be a straight segment connecting two shapes substantially circular placed at the ends of this segment.
  • the mobile and fixed supports would have complementary shapes adapted to allow the necessary rotation and translation operation according to the invention.
  • the slides 2 made by sections of the profile are economical, robust, reliable in their shape and easily mountable in large series.
  • the mobile support 3 is one with the element 4. It is equally conceivable that it is planned between the movable element 4 and the mobile support 3 of the adjustment means of the relative height of these two elements.
  • the fixed support 1 is only one with the fixed wall 9. It is just as possible that it is planned between the fixed wall 9 and the fixed support 1 of the adjustment means of the relative height of these two elements.
  • a preferred embodiment of the invention uses a stainless steel slide or any other material resistant to oxidation and fixed supports 1 and mobile 3 made of plastic anti-friction or covered with such material.
  • This embodiment presents an increased comfort for the user because the efforts of handling are all the weaker as friction is reduced.
  • Such material for use in a dishwasher could be a polymer (such as POM or polyoxymethylene), preferably loaded with anti-friction material, such as graphite, or PTFE fluorinated material (Polytetrafluoroethylene).
  • At least one of the axes A or B could be positioned on the very soul of slider 2 and the rotation around this axis would be made possible by the deformation of the slider 2 or by the presence of a hinge materializing this axis.
  • First characteristic the operating clearance depends on the thickness of the slider 2, for example stamped piece for which the manufacturing accuracies are excellent and this game is, in addition, independent of an assembly or shaping.
  • Second characteristic the operating clearance is not disturbed by the retrofit of the building set J c because it is the rotational movement of the sliders 2 relative to the fixed supports 1 and mobile 3 which fulfills this role.
  • the operating clearance, clearance between the surface of the housing 6 and 6 'and the slider 2 is guaranteed by these two characteristics.
  • the invention responds to the need to dissociate the games necessary for functioning of those inherent in the construction. It can be from by its simple and robust design integrated into a device appliances that may be a dishwasher, oven or refrigerator, taking into account the constraints, in particular temperature, specific to each type of device or suitable for any type drawer.
