Definitions

  • the present invention refers to a new construction applied to mobile shelf for refrigerators and freezers of the type that comprises a cabinet defin- ing inwardly at least a refrigeration chamber provided with a access anterior opening closed by respective door, wherein said shelf is displaceable horizontally between a retracted position and a forward position, and back to the retracted position, by user specific actuation without requiring the latter to exert, on the shelf, a continuous tensile force to produce its displacement between the retracted position and the forward position.
  • the invention is particularly useful when applied to mobile shelves, built as usual drawers provided inside the refrigeration chamber of a refrigerator or freezer, to define a subchamber, someway apart from the rest of the refrigeration chamber and which access is only achieved with a linear displacement of said shelf from a retracted position to a forward position.
  • a mobile shelf that can resemble to a drawer, to be mounted inside refrigerators and freezers of the type herein considered, and that can be easy and quickly displaced from a retracted position to a forward position, making it easier products loading and unloading, without requiring a manual tensile force actuation by the user.
  • the mobile shelf of the invention comprises an actuator device having a tubular body fixed to one of the parts of the shelf and cabinet and from which projects, axially, an impeller rod having a free end to be kept seated against other of said parts in a inoperative armed position of the actuator device, achieved when the shelf is displaced backwards, to a retracted position, and yet in a operative distended position of actuator device, in which the shelf is displaced forward, to a forward position.
  • the actuator device of the invention is actuated from inoperative armed position to a operative distended position, when applying a backwards axial instantaneous manual force against the shelf, in its retracted position and the actuator device being conducted, from operative distended position to an armed position, by manual displacement of the shelf, from forward position to a retracted position.
  • the proposed construction of present invention allows that the actuator device displaces the shelf or drawer from retracted position to forward position when user applies, against the still in retracted position shelf, a backwards instantaneous axial force, which force is capable of triggering the actuator device, that, once distended, causes desired displacement of mobile shelf or drawer to the forward position.
  • a backwards instantaneous axial force which force is capable of triggering the actuator device, that, once distended, causes desired displacement of mobile shelf or drawer to the forward position.
