Hinge with tight fit between base plate and adapter

In a hinge including a base plate having first and second longitudinally spaced ends, opposite sides, a transverse notch formed in said first end and latching means formed at said second end, a hinge arm, an adapter adjustably supporting said hinge arm for mounting said hinge arm on said base plate and having first and second longitudinally spaced ends, said adapter having U-shaped configuration including opposite, longitudinally extending side arms, a transverse pin extending between said side arms at said first end of said adapter, said pin fitting in said notch in said first end of said base plate and thereby forming a pivot about which said adapter and said hinge arm are pivotable with respect to said base plate, and a rocker lever mounted at said second end of said adapter for engaging said latching means at said second end of said base plate when said adapter and said hinge arm are pivoted about said pivot toward said base plate, thereby fastening said adapter to said base plate, the improvement comprising means for ensuring that said adapter fits tightly on said base plate without transverse or lateral play therebetween, said ensuring means comprising:

• inner surfaces of said side arms of said adapter being spaced from each other in an unstressed state by a first distance less than a second distance between outer surfaces of said opposite sides of said base plate, and at least one of said side arms having a weakened area enabling said at least one side arm, upon said adapter being pivoted toward said base plate, to deform laterally outwardly, such that said inner surfaces of said side arms of said adapter tightly grip said outer surfaces of said sides of said base plate;
• and
• said transverse pin and said notch having respective longitudinal center axes extending in an untensioned state at an angle to each other, such that upon said transverse pin being fit into said notch to conform thereto said adapter is twisted, thereby causing said inner surfaces of said side walls to further grip said outer surfaces of said sides.
