     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings the numeral 10 generally designates a cabinet base which is adapted to be connected to a cabinet top 12 by means of a hinge 14. Cabinet base 10 includes side walls 16, 18 each of which includes a top edge 20 having a base flange 22 extending horizontally inwardly therefrom. Extending upwardly from the inner end of the base flange 22 is upstanding flange 24. 
     A lower opening 26 is provided in side wall 18 and includes an upper edge 28, a lower edge 30, and opposite side edges 32. A corner opening 34 is provided at the corner or juncture of the base flange 22 and the upstanding side wall 18. Corner opening 34 includes an upper edge 36, a lower edge 38, and two opposite side edges 40. 
     Cabinet top 12 includes a control panel 42, a top panel 44, and a side panel 46 extending around the margins of top panel 44. Extending inwardly from the lower edge of side panel 46 is a top flange 48. Side panel 46 includes an upper opening 50 therein which includes a top edge 52, a lower edge 54, and opposite side edges 56. 
     Hinge 14 includes an upper hinge member 58 having at its upper edge an upper clip 60 which in turn includes a doubled back spring finger 62 at its outer end. At the lower edge of upper hinge member 58 is a J-shaped clip 64 having a long leg 66, a short leg 68 and a slot 70 therebetween. Upper hinge member 58 includes a reduced thickness portion 72 which permits the upper hinge member 58 to flex about a horizontal axis. 
     Extending between the upper hinge member 58 and lower hinge member 75 is a living hinge 74. The entire hinge 14 is preferably formed from a plastic material and is of unitary construction. However, the hinge member 14 can be formed of separate parts, and the living hinge 74 may be varied in its construction from the living hinge structure shown in the drawings. 
     Hinge 14 also includes the lower hinge member 75 having at its lower edge a lower clip 76 which on its end includes a doubled back spring finger 78. At the upper edge of lower hinge member 75 is a V-shaped clip 80 which is comprised of a first leg 82 and a spring leg 84. The juncture between the first leg 82 and the remainder of lower hinge member 75 forms a slot 86. Lower hinge member 75 also includes a reduced cross section portion 88 which enables the lower hinge member 75 to flex about a horizontal axis. 
     The hinge 14 is used to assemble the cabinet top 12 to the cabinet base 10 in the following manner. First the upper hinge member 58 is attached to the cabinet top 12 by inserting top flange 48 of cabinet top 12 into the slot 70 of the J-shaped clip 64. The reduced thickness portion 72 permits flexing of the upper hinge member 58 during this process. Next the upper clip 60 is pivoted into the upper opening 50 of side panel 46. During insertion, the spring finger 62 is cammed inwardly to a folded position, but after the upper clip 60 has been fully inserted into the opening 50, the spring finger 62 springs back to its original normal locked position wherein it engages the interior surface of the side panel 46 as shown in FIG. 4. 
     Next, the V-shaped clip 80 is inserted downwardly into the corner opening 34 of cabinet base 10 with the lower edge 38 of the corner opening 34 being fitted within the slot 86 of the lower hinge member 75 as shown in FIG. 4. As the V-shaped clip 80 is inserted into corner opening 34, the spring leg 84 is cammed inwardly to a folded position. When clip 80 is fully inserted into corner opening 34, spring leg 84 will return to its original position, thereby locking clip 80 into corner opening 34. Upon completion of this process, the lower clip 76 is moved into the lower opening 26 and the spring finger 78 deflects to its folded position. Once the lower clip 76 has been completely inserted into the lower opening 26, the spring finger 78 springs outwardly to its locked position and engages the interior surface of the side wall 18 of base 10 thereby locking the lower clip member 75 to the cabinet base 10. 
     The side margins 32, 40, and 56 of the openings 26, 34, and 50 respectively are sized so as to prevent the hinge 14 from moving laterally therein, and this prevents side to side movement of the cabinet top 12 relative to the cabinet base 10. 
     The shape of the hinge is such that it can be formed either by extrusion or it can be injection molded using a &#34;straight-pull&#34; mold design. The hinge provides sufficient range of movement of the cabinet top to the cabinet base so that the cabinet top can be pivoted to a full open position for servicing. 
     One important feature of the present invention is the fact that the long leg 66 of the J-shaped clip 64 is inserted between the top flange 48 of the cabinet top 42 and the base flange 22 of the cabinet base 10 so that the cabinet top 12 and the cabinet base 10 are isolated from one another and are prevented from metal to metal contact with respect to one another. The plastic of the long leg 66 further provides a cushion between the cabinet top 12 and the cabinet base 10. 
     In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, these are used in a generic and descriptive sense only and not for purposes of limitation. Changes in the form and the proportion of parts as well as in the substitution of equivalents are contemplated as circumstances may suggest or render expedient without departing from the spirit or scope of the invention as further defined in the following claims.
An appliance hinge connects a cabinet top to a cabinet base for pivotal movement therebetween. The hinge includes a first hinge member attached to the cabinet top and a second hinge member attached to the cabinet base. The first and second hinge members are pivotally connected to one another. One of the first and second hinge members includes a leg extending between the cabinet top and the cabinet base to prevent contact therebetween.
