Definitions

  • the present invention relates to a cooling device comprising a height adjustable shelf.
  • the aim of the present invention is the realization of a cooling device which comprises a shelf disposed on the door and the position of which can be changed by being moved in the vertical direction.
  • the cooling device of the present invention comprises a control lever located between the door and the shelf, that extends in the movement direction of the door-mounted shelf in the vertical plane, and moving the shelf upwards and downwards by being rotated around the vertical axis, at least one channel situated on the door and a height adjustment mechanism having a pin borne in the channel such that it can be moved by the control lever.
  • the position of the shelf in the door can be changed by rotating the control lever moving together with the shelf.
  • control lever comprises a worm gear located thereon and a handle that is utilized for rotating the worm gear by being turned.
  • the shelf remains in its position at the moment the user stops rotating the handle without requiring to use a separate stopping mechanism.
  • the height adjustment mechanism comprises at least one shaft on the rear wall of the shelf facing the door and at least one gearwheel fastened on the shelf by being inserted to the shaft to be co-operating together with the worm gear, whereto the pin is secured on its frontal surface.
  • the motion transferred to the pin by worm gear gains flexibility by means of the gearwheel.
  • the height adjustment mechanism comprises two gearwheels disposed on both sides of the worm gear to operate reciprocally with the worm gear and which rotate in opposite directions to each other as the worm gear is rotated.
  • gearwheels As the worm gear is rotated, gearwheels, the cogs of which contact the cogs of the worm gear, also rotate. While the horizontal component of the angular motion created on the gearwheels provides the pins to make linear motion in the bearing, the vertical component provides the gearwheels and the shelf whereto the gearwheels are connected to move linearly in the vertical direction.
  • the position of the shelf in the door can be adjusted by moving thereof upwards or downwards depending on the need of the user.
  • the height adjustment mechanism comprises two L shaped channels facing each other, whereof the horizontal portions extend in the same direction.

  • the channel (8) extends almost in the horizontal plane and the pins (7) borne therein move linearly in the channel (8).
  • the height adjustment mechanism (17) comprises two "L" shaped channels (8).
  • the channels (8) are positioned on the inner surface of the door (3) such that their portions extending parallel to the horizontal plane face each other.
  • the pins (7) located on the frontal surface of the gearwheels (5) fastened so as to operate reciprocally with the worm gear (6) attached on the shelf (4), are inserted through the upper end of the vertical portion of each channel (8) ( Figure 5).
  • the shelf (4) is slid in the vertical plane such that the pins (7) are seated in the horizontal portion of the channels (8).
