Definitions

  • the present invention relates generally to a device for opening and/or closing a drawer such as a vegetable box of a refrigerator.
  • a vegetable box 6 is formed in the lower part of the main body la of a conventional refrigerator, as shown in Figs. 1 and 2.
  • a user may open and close the vegetable box 6 using a door 3a of the vegetable compartment in the manner of a drawer.
  • the magnetic force of the door gasket tends to weaken after a long period of use, so that the door 3a of the vegetable compartment is no longer satisfactory sealed to the main body la of the refrigerator. This means that cool air leaks outside the main body la of the refrigerator.
  • the conventional refrigerator has the disadvantages of a loss of power in the refrigerator and a drop in efficiency.
  • the object of the present invention is to overcome the problems and disadvantages of the conventional device, that is, to provide a mechanism for opening and closing a vegetable box of a refrigerator to or from which a user can easily place or get food such as vegetables and fruit without the seal being subject to deterioration over time.
  • a drawer mechanism for enabling a drawer to slide into and out of a cabinet, comprising: guide rails to be fixed to wall surfaces of the cabinet to guide movement of the drawer; sliders adapted to move along the guide rails; and drawer support members on both sides of the drawer and moving forward and rearward along with the sliders as the drawer is opened or closed; wherein the guide rails, sliders and support members include gravitational locking means such that in the closed configuration of the drawer the weight of the drawer acts constantly to exert a force maintaining this closed configuration.
  • the mechanism includes a vegetable box formed in the lower part of the main body of the refrigerator for receiving food like vegetables and fruit, guide rails fixed to wall surfaces in the lower parts of the main body of the refrigerator to guide movement of the vegetable box, sliders inserted into the guide rails and having a plurality of rollers, supporting members mounted in both sides of the vegetable box and moving straight forward and rearward along with the sliders by rotating the rollers when the vegetable box opened or closed, and a gravitational locking means for unit the supporting members with the guide rails by the weight of the vegetable box itself when the supporting members and the vegetable box are completely inserted into the lower part of the main body of the refrigerator.
  • Each slider preferably has a roller at its front end which in the closed position of the drawer, as defined by a sealing gasket being pressed around the drawer opening in the cabinet, is situated between the slopes of the guide surfaces to provide the necessary inward closing force component.
  • guide rails 2 are formed at both wall surfaces of an inner case in the lower part of the main body 1 of the refrigerator, for guiding a drawer for use as a vegetable compartment, for instance.
  • the rails have raised sections or upper projections 2a formed at their forward ends.
  • Sliders 5 moving forward and rearward when the door or panel 3 of the drawer is pulled or pushed are mounted on the guide rails 2.
  • the sliders 5 have a plurality of rollers 4.
  • Support members 7 constituted as arms of a U-shaped frame are united with the door 3 of the vegetable compartment, and a vegetable box 6 is mounted in the supporting members 7.
  • the supporting members 7 are moved along with (or roll on) the sliders 5 by a frictional force of the rollers 4 when the door 3 of the vegetable compartment is pulled or pushed, a downward-facing guide groove 8 being formed in each supporting member 7 for contact to the upper surfaces of the rollers.
  • Stops 9, for pushing the sliders 5 as the door 3 of the vegetable compartment is closed, are formed in the forward upper end portion of each supporting member 7, and slant surfaces 7a corresponding to the upper projections 2a of the guide rails 2 are formed in each forward lower end portion of the supporting members 7, thus giving the grooves 8 a ceiling near their front ends which first slopes and then runs horizontally at a higher level up to the door 3.
  • a gravitational locking means is constituted by the upper projections 2a raised above the rest of the guide rails 2 at the front and the rollers 4 formed at the front of the sliders 5 and operating against the slant surfaces of the upper projections 2a under gravity when the vegetable box 6 is substantially completely inserted into the lower part of the refrigerator.
  • a user wants to open the door 3 of the vegetable compartment in the lower part of the main body in the refrigerator, he pulls the door 3 in the direction of the arrow.
  • the rollers 4 of the sliders 5 are in this closed position pressed between the slanting part of the upper projections 2a of the guide rails 2 and the slant surfaces 7a in the forward lower end portions of the guide grooves 8 of the supporting members 7.
  • This configuration ensures a force component in the closure direction resulting from the weight of the drawer.
  • the rollers move forward by the friction force, sliding over the upper projections 2a formed in each forward end portion of the guide rails 2.
  • the refrigerator according to the above embodiment has the advantage that the user can easily get the food such as vegetables or fruit into or out of the vegetable box 6 since the door 3 of the vegetable compartment sags down slightly when pulled, after the front rollers drop off the end of the guide rails.
