Definitions

  • the present invention relates to a device for adjusting height at least two different positions.
  • Some machines or devices may have a element which can occupy at least two different height positions, element that must be able to be moved manually, or so motorized, easily, without having to handle blocking devices and without exerting a force greater than that necessary to lift this item if it was out of the device containing it.
  • This is the case, for example, of the upper basket of a dishwasher, which can be moved between a low position and a high position, so that it can be adapted to loads of dishes of different heights.
  • the subject of the present invention is a device for adjusting height, in at least two different positions, of a movable element of machine, which is simple to make and handle by a user, without require its share of action other than that of raising this element, and to accompany his descent, if necessary, that is to say without having to pull or push an auxiliary part to unlock a position of this element, or move this element laterally.
  • this height adjustment In the case of application to upper basket of a dishwasher, this height adjustment must be even when the basket is full of dishes, and without having to disengage the basket from the machine slides.
  • the device comprises, in at least one side walls of the machine frame, walls along which is moved the movable element, a cut made in correspondence with each of the positions that this movable element must be able to occupy, each cutout, except the lowest, with a bearing surface oblique to the surface of the walls, a shuttle being arranged in each of the cutouts corresponding to the positions other than the position the lower part of the movable element, this shuttle being able to move in the cut parallel to the surfaces of the walls, the surface of this shuttle, shaped toward the movable member, being substantially coplanar with the surface from the wall corresponding to the lower end of the shuttle, and set back of this wall surface over the rest of the length of the shuttle, the cutouts relating to the different height positions of the movable element being aligned on at least one axis parallel to the direction of travel of the movable element, the movable element comprising, on its opposite faces walls in which the cuts are made, in correspondence with each cutting axis, a snap
  • Each shuttle has, on its side facing the element movable, an oblique face approaching, at its lower part, the element mobile and on which comes to slide by leaning said spout of the element latching up and passing at its height, thus forcing the shuttle to get off.
  • the latching element is a tongue elastically connected by one of its ends to the movable element and capable of fade into a cavity in the element, this tab extending parallel to the corresponding wall and to the direction of displacement of the movable element, the outer face of the body of this tongue being coplanar with the face of the movable element, the free end of the tongue forming said beak projecting towards the outside of the body, the front end of this beak being substantially perpendicular to the wall of the frame and connecting obliquely to the body of the tongue.
  • the invention is described below with reference to a dishwasher, but it is understood that it is not limited to this single application, and that it can be implemented for any device in which an element mobile (such as a locker, drawer, storage area, component ...) must be able to occupy several height positions different, the movements of this element being carried out by hand, vertically or roughly vertically.
  • These displacements could be carried out mechanically (by levers, using pulleys) or, at the limit by motors, but in this last case the cost price of devices could be increased significantly, which would not be a good solution, especially since we know motor solutions in which the devices integral with these motors (for example screws endless) are used to maintain at any height position the driven elements.
  • the dish basket should only occupy two different height positions, but it is understood that the invention can be applied to cases where the element mobile must occupy more than two different height positions.
  • the mobile element which must occupy at least two positions in different height, can move obliquely.
  • the device of the invention uses as many walls of the frame as necessary to keep the movable element in the selected position, and this frame can be fixed or mobile (for example in the case of telescopic mounting).
  • the basket is, in this example, guided vertically by slide devices (not shown), the fixed part of which is fixed to the intermediate piece, and the movable part on the side faces of the basket. So the basket always remains horizontal, and it a snap device is sufficient for each of its side faces.
  • a recess 4 having for example a rectangular opening, leaving remain a tongue 5 of elastic material, extending parallel to the direction of movement in height of the basket 1, above the bottom, generally flat of the recess 4, the tongue 5 being attached to the basket 1 body by its lower end, the other end (6) of the tongue 5 being free and able to be moved towards the interior of the indentation 4 when a force is applied to it in the corresponding direction.
  • the outer surface of the tongue 5 is coplanar with the plane of the face corresponding side of the basket, apart from the upper end 6 of the tongue 5 which forms a beak 7 projecting towards the outside of the basket by relative to this surface.
  • the rear face 8 of the end 6 of the tongue 5 is oblique to the direction of movement of the basket 1 and to side faces of basket 1, its free end being lower than its end connected to the body of the tongue 5.
  • This face 8 forms a bearing surface cooperating with the bearing surfaces, described below, the recesses made in part 2.
  • the face oblique exterior of the spout 7 (the one facing the tank wall corresponding) is referenced 7A. Tabs 5 and recesses 4 can be formed in the side walls of basket 5 if the latter is produced by plastic molding.
  • the device of the invention comprises, in the uprights 2A, 2B of the part 2 cutouts.
  • the cutouts 10 are “simple” cutouts not comprising "Shuttles” (unlike other cuts, which include shuttles, as described below).
  • the cutouts 10 include a first surface 11 perpendicular to the corresponding wall, and a second oblique surface 12, joining the bottom of surface 11 to the surface of the corresponding wall.
  • these cutouts 10 have, in section transverse (in the drawing plane), a wedge shape.
  • the depth of cutouts 10, at the surface 11, is sufficient to accommodate the spout 7 of the tongue 5, without exerting lateral force on this tongue when its surface 8 is close to the surface 11.
  • the locations cutouts 10 and tabs 5 are such that when the surfaces 8 are close to the corresponding surfaces 11, the basket 1 is effectively at the lowest desired position. In this position, the basket 1 rests on crosspiece 3 of part 2.
  • the means defining the high position include essentially, in addition to the tabs 5, a cutout 13 and a “Shuttle” 14 for each tab 5.
  • the cut 13 a in section (in the drawing plane) a roughly rectangular shape, the rectangle as well formed having its long sides parallel to the uprights 2A, 2B respectively.
  • the small bottom side of this rectangle forms a surface support 15 substantially parallel to the corresponding surface 8.
  • This surface 15 does not extend over the entire depth of the cutout 13. From the side of basket 1, it is limited by an oblique surface 16 which is set back from the wall (2C or 2D respectively) of a few millimeters.
  • This surface 16 joined the level of the wall (2C or 2D) down to the cutout 10 (in the case shown in the drawing, since the two positions of the basket are relatively close together, the surface 16 almost reaches the wall plane (2C or 2D) at its junction with the surface 12 of the cutout 10 corresponding).
  • the surface 15 stops at a cutout 17 intended to receive the end of a "tooth" or lower leg 18 of the shuttle 14.
  • the bottom surface 19 of the cutout 13 is parallel to the wall (2C or 2D), and it joins by a short surface oblique 20 the edge of a housing 21 in which the "head" can move or upper end of the shuttle 14.
  • This housing 21 has, in section (in the plane of the drawing) a rectangular shape extending parallel to the wall (2C or 2D) closed at its upper end and open at its lower end, thus communicating with the cutout 13.
  • a low wall thickness remains between the housing 21 and the visible inner face of this wall.
  • the shuttle 14 has a general shape of a fork with two teeth. Its head 22, of rectangular shape, can slide in the housing 21. Its two "teeth" 18 and 23 are connected to the head 22 by a narrow body 24. In low position ( Figures 1 and 3), the shuttle 14 rests on the surface 15. The sides, considered in the planes perpendicular to the plane of the drawing, the body 24 are connected by oblique surfaces 25, 26 to the sides of the teeth 18, 23 (also considered in planes perpendicular to the plane of the drawing).
  • the length of the shuttle 14 is such that in its low position, the top of its head 22 is slightly engaged in its housing 21, and that its high position, the top of its head abuts against the upper bottom of the housing 21, its surface 25 being close to the surface 20 or in abutment against she.
  • all the cuts 10 and 13 cooperating with the same tab 5 are aligned on the same vertical axis (parallel to the direction of moving the basket between its upper and lower positions).
