Definitions

  • the present invention refers to a movable compartment engagement system for household appliance, said system being designed, more specifically, for making the engagement of sliding drawers safer and versatile in household refrigerators, besides of allowing the variation of the amount and configuration of compartments of a certain storage space in a completely new fashion when compared with the current state of the art.
  • drawers are removable and sliding, constructed in order to cooperate with tracks existing on the walls of the cooled compartment, wherein, in general, said tracks comprise cavities on which the drawers edge structures are simply supported or alternatively casters are attached thereto to facilitate the sliding of the drawers when closing or opening.
  • drawers jamming often occurs during closing or opening, since if it is improperly handled - by only one of the user's hands or pushed / pulled by near regions of its sides - there is a horizontal displacement diagonally thereof, resulting in inconvenience that compromise their proper handling.
  • FIG. 1 schematically illustrates how the misalignment of the refrigerator drawers occurs during the sliding.
  • This Figure illustrates, in schematic cross-sectional view, a refrigerator cabinet 10 with an inner compartment 11 comprising side tracks 12 cooperating with its side walls 13, wherein the side tracks 12 slide on the side edges 21 of a movable compartment or drawer 20.
  • the horizontal misalignment of the drawer occurs generally due to the clearance afforded by the width "d" of the tracks 12 - which exists to enable the engagement and the movement of the drawer 20 - associated with large longitudinal dimension "D" of the drawer which, as it is inserted into the inner compartment 11, creates an imaginary diagonal displacement trend line that makes up the front surface projection of the cabinet 10 at an angle "a” that increases as the drawer 20 is inserted into the inner compartment 11 and because of this, will increase the possibility of displacing and jamming.
  • Document US6945617 describes a track for sliding drawers whose construction results in a horizontal thin span for the passage of the support edge thereof, and although this will be able to reduce the undue horizontal and vertical movement of the drawer, during its opening or closing, it can hinder the sliding thereof, besides requiring the use of metal screws for fixing the refrigerator cabinet inner compartment, making the installation more complex.
  • document KR2008029046 discloses a drawer assembling structure which comprises using, between the track and the cabinet surface in which it is installed, a spring which, through the pressure exerted on the track, tends to compensate the horizontal displacement of the drawer and thereby reducing said clearance, and hence the misalignment.
  • a spring which, through the pressure exerted on the track, tends to compensate the horizontal displacement of the drawer and thereby reducing said clearance, and hence the misalignment.
  • Document JP4254670 discloses a removable structure which allows using, instead of a single large tray, several drawers of different storage capacities. However, it is a horizontal structure which interferes with the entire base of the cooled compartment and on which other drawers are supported, also presenting significant limitation with respect to variability of internal volumes of storage products.
  • Document BR PI0504387-5 describes a vertical structure to be engaged within the inner compartment of a refrigerator appliance having a support function for the engagement of other internal components, for example, drawers. Such a solution, however, does not address the possibility of variation of the refrigerator compartment intended specifically for the installation of the vegetable drawer nor the particulars of its installation and use.
  • the present invention aims primarily to solve the technical problem of undue movements and consequent horizontal and vertical misalignment that occurs with drawers of household appliances - especially refrigerators - when opening or closing for use, and optionally promote such benefits together with the possibility of modularization of a cooled compartment for storing a sliding drawer.
  • the main objective of the present invention is to reveal a movable compartment engagement system for household appliances that, without comprising a plurality of constituent elements, minimizes to the maximum the possibility of displacement in horizontal and vertical directions during handling the compartments, in order to avoid undue disengaging and falls.
  • Another objective, among others of the present invention, is to reveal a track-engagement system that does not require the installation of additional components in the drawers that will cooperate therewith, in order to make a cheaper and practical production of both tracks and drawers when assembling the system.
  • one of the objectives of the present invention is to disclose a movable compartments engagement system for household appliances that is built into a structure capable of allowing environmental modularization intended to house the drawers in the appliance, in order to allow performing layout changes and subdividing the area in several compartments of different storage capacities in a practical and simple way.
  • a movable structure comprising movable compartments engagement system for household appliances cooperating with existing engagement systems in the inner compartment of the appliance to allow changing the arrangement and number of drawers for storage of various products.
  • a cabinet comprising side walls delimiting at least one inner compartment capable of housing at least one movable compartment with side upper edges comprising skirts projecting downwards
  • the system comprising at least one sliding means cooperating with the left side wall of the cabinet and with the skirt extending from the upper edge of the right side wall of the movable compartment and the least one sliding means cooperating with the right side wall of the cabinet and with the skirt extending from the upper edge of the left side wall of the movable compartment.
  • said engagement system comprises the following essential characteristics:
  • said sliding means comprise, on the inner side of the side surfaces thereof, at least one resilient element cooperating with the skirt of the movable compartment, wherein said resilient elements comprise side surfaces cutouts which acquire a convex surface form protruding for the inner region of the sliding means (100, 200) after fastening the sliding means (100, 200) to the sidewalls (131, 132) of the cabinet (10).
  • the sliding means preferably comprise, on the outer side of its side surfaces, at least one engagement element cooperating with the side walls.
  • the invention is also characterized by the fact that said system comprises means for eliminating side movement clearances of the movable compartment, means for eliminating possible diagonal displacement of the movable compartment during its movement, and means for absorbing variation in the movable compartment assembling, wherein the means for eliminating side movement clearances of the movable compartment comprises semicircular protrusions and longitudinal slots; wherein the means for eliminating possible diagonal displacement of the movable compartment comprises a lower inner channel, and wherein the means for absorbing variation in the movable compartment assembling comprises at least one semicircular protrusion.
  • the sliding means comprise members made of non-metallic material, and the at least one engagement element cooperates with the side walls of the cabinet by one of the following means: snap, interference or snap-fit.
  • This invention also comprises a movable structure comprising movable compartment engagement systems for household appliances, specifically for refrigerators apparatus, defined by a cabinet comprising side walls and back and lower surfaces delimiting at least an inner compartment capable of housing at least one movable compartment having side upper edges comprising skirts protruding downwards, said movable compartment cooperating with at least one slide means cooperating with the left side wall of the cabinet and the skirt extending from the upper edge of the right side of the movable compartment, and at least one slide means cooperating with the right side wall of the cabinet and the skirt extending from the upper edge of the left side wall of the movable compartment, characterized by the fact that said movable structure comprises a member removably cooperating with the back and lower surfaces of the cabinet, said member comprising left side surface comprising at least one slide means cooperating with a movable compartment and the left side surface comprising at least one slide cooperating with a movable compartment.
