Definitions

  • the invention relates to a height-adjustable foot system remotely controllable for furniture equipment, especially for built-in household appliance.
  • the object of the invention is to remedy this drawback by simplifying the adjustable feet system.
  • a foot system adjustable in remote controllable height for furniture equipment especially for built-in or built-in household appliance, of the type comprising a foot threaded spindle screwed into a thread integral with the chassis the equipment and driven in rotation by a toothed wheel which is linked to it in rotation, said wheel being part of a wheel transmission mechanism and worm, said worm being rotated by a device remote control, the system being characterized in that said wheel has an upper collar with a diameter greater than that of the bottom of toothing of the wheel and in that said worm is arranged and maintained in a chassis housing close to the thread so that it come to cooperate with said wheel and keep it in axial translation by by pressing the collar on the screw.
  • the retention in place of the toothed wheel is ensured by the single worm, the toothed wheel not having to transmit the weight of the device, and the worm is housed directly in a housing of the device chassis.
  • the invention provides a mounting method extremely simple of this system.
  • Figure 1 a general view of an apparatus household, here a dishwasher, equipped according to the invention.
  • Device 1 has a front face 100, a rear face 101, a frame 102 and rear legs adjustable in height 2 controlled from the front using a rod 3, as will be seen in more detail in the following description.
  • FIG. 2 is an exploded isometric perspective view of the rear right of the chassis alone with the remote adjustable foot system thanks to a control rod 3.
  • the foot 2 has a pin threaded 20 resting on the ground by a base 22 which can be provided with a wafer (not shown) ensuring sliding in rotation on the ground.
  • the threaded pin 20 can be screwed into a female thread 103 secured to the chassis 102.
  • the spindle also comprises at least one longitudinal groove 21, the role will be specified later.
  • the spindle is rotated by a toothed wheel 5 making part of a worm and wheel transmission mechanism whose screw 4 is controlled by the rod 3.
  • FIG. 3 shows this mechanism.
  • the wheel 5 has a upper flange 50 whose diameter is greater than that of the bottom of gear teeth.
  • the toothed wheel is pierced with an axial hole for the passage of the threaded spindle 20, this hole being provided with lugs 51 which must engage sliding in the grooves 21 of the spindle so as to ensure the free sliding of the wheel on the spindle while ensuring a connection in rotation to control the rotation of the spindle.
  • the worm screw 4 the thread of which cooperates with the teeth of the wheel 5, is terminated symmetrically by two at its ends identical cylindrical rings 41 and 43 with an axial housing, 42 for the ring 41 or for each of the two rings 41 and 43, comprising a part frustoconical entry followed by a part ensuring the connection of shape, for example by a square or hexagonal shape, with the end of the control rod 3.
  • the frusto-conical part guides the rod, which is removable, when introduced into the screw.
  • FIG 4 is shown more precisely the adjustment system installed, element 4.1 representing the worm before mounting.
  • element 4.1 representing the worm before mounting.
  • the screw 4 is held in place downwards by a tongue 104 secured to the chassis. It is held in axial translation by a stop 105 retaining the ring end of the screw.
  • the tongue 104 has an interior shape matching the cylindrical shape of the screw but in fact only needs a contact according to a longitudinal line positioned to prevent escape of the screw to the bottom. That is, the width of the opening between the toothed wheel and the edge of the tongue 104 must be less than the diameter of the screw, as see it better in Figure 5.
  • FIG. 5 is a sectional view of the adjustable foot system according to the invention.
  • the foot 2 with the threaded pin 20 and the base 22, the internal thread 103 in the frame 102, the toothed wheel 5 and the screw endless 4 in their operating position after assembly.
  • the screw end 4 is disposed in a housing 111 of the chassis 102.
  • This housing is delimited by the tongue 104 and a flexible rib 6 secured to the chassis, whose ground plane substantially by the axis of the screw 4 to prohibit the ascent.
  • the worm 4 in taken with the toothing of the wheel 5 prevents it from falling out thanks to the support of the flange 50 on the screw itself, without any other device for holding or intermediate piece.
  • the assembly of the system is very easy by maintaining the wheel 5 against the internal thread 103 thanks to the base 22 of the screwed foot 2 completely on the thread, presenting the screw in the opening 110 of the chassis housing (positions 4.I then 4.II) then pushing the screw against the resistance of the rib 6 which, being flexible, disappears up to position 60 before returning to its normal position by locking the auger in his accommodation.
  • Figures 6 and 7 show views of the housing in the chassis 102, respectively according to arrows A and B in Figure 4. We can note the position of the rib 6 and the tongue 104.
  • the housing 111 is completed by the stops 105 and 106 for the rings 41 and 43 of the worm, stops which prevent any axial translation of the screw ( Figure 7).
  • adjustable foot system according to the invention can also be applied to any furniture equipment (cupboards, etc.) requiring an upgrade.
