Self-closing refrigerator door

In a self-closing refrigerator door assembly of the sliding type having a frame mounted in a refrigerator wall opening, said frame having a pair of parallel adjacent tracks depending from the upper portion thereof and a pair of parallel adjacent tracks protruding from the lower portion thereof, inner and outer doors each having a channel in the upper portion thereof mateable with said depending tracks and each being supported on rollers, each of said doors being mounted on one of said pair of upper and lower tracks for translatory movement in said frame, a closing system for each door including an elastic means secured at a first end to said door in the direction of opening, means for guiding said elastic means to the underside of said door for engagement with the lower portion of said frame, the improvement comprising a means for adjusting said elastic means, said adjusting means including a rotatable drum attached to the side of said door in the direction of opening to which is windably attached said first end of said elastic means and means releasably engageable with said rotatable drum for preventing rotation thereof, whereby upon release of said engaging means said first end of said elastic means may be wound or unwound on said rotatable drum by the rotation thereof to vary the stored energy in said elastic means.
