## Abstract

A receptacle for an associated appliance hinge includes a receptacle base and a breakaway lever movably connected to the receptacle base. The breakaway lever includes a cam edge. A first mounting structure is connected to the receptacle base and adapted to be engaged by an associated hinge arm. A second mounting structure connected to the breakaway lever such that the second mounting structure is movable relative to the receptacle base. The second mounting structure is adapted to be engaged by the associated hinge arm. A breakaway latch is connected to the base and includes a cam follower engaged with the cam edge. The breakaway latch further includes a spring that biases the cam follower into abutment with the cam edge. The breakaway lever is selectively movable from a first position where the cam follower is engaged with a first location on the cam edge to a second position where the cam follower is engaged with a second location on the cam edge.

## Claims

### Claim 1

A receptacle for an associated appliance hinge, said receptacle comprising:
a receptacle base adapted to be connected to an associated appliance body adjacent an opening of a chamber;
a breakaway lever pivotally connected to the receptacle base, said breakaway lever comprising an inner end, an opposite outer end spaced from said inner end, and a cam edge located at said outer end, wherein said breakaway lever is pivotally connected to the receptacle base between its inner and outer ends by a pivot fastener engaged with said breakaway lever and said base;
a first hinge mounting structure directly connected to the receptacle base and adapted to be engaged by an associated hinge arm, said first hinge mounting structure fixed in position relative to said receptacle base;
a second hinge mounting structure located at and defined by said inner end of said breakaway lever such that said second hinge mounting structure moves relative to the receptacle base and moves relative to said first hinge mounting structure when said breakaway lever pivots relative to said receptacle base, said second hinge mounting structure comprising a slot formed in said inner end of said breakaway lever that is adapted to receive a tip of the associated hinge arm;
a breakaway latch connected to the receptacle base and comprising a cam follower engaged with said cam edge, said breakaway latch further comprising a spring that biases said cam follower into engagement with said cam edge;
said breakaway lever selectively movable from a first position where said cam follower is engaged with a first location on said cam edge to a second position where said cam follower is engaged with a second location on said cam edge, wherein said first location on said cam edge comprises a home location and said second location on said cam edge comprises a breakaway location spaced apart from said home location, said cam edge further comprises a transition surface that extends between and interconnects the home location and the breakaway location;
wherein: (i) said cam follower is located at said home location when said breakaway lever is located in said first position; (ii) said cam follower is located at said breakaway location when said breakaway lever is located in said second position; and (iii) said cam follower is in contact with said transition surface when said breakaway lever is located between said first position and said second position;
said breakaway latch comprising:
a latch base connected to the receptacle base;
a spring rod slidably connected to the latch base by a follower fastener, wherein said spring comprises a coil spring coaxially positioned about said spring rod that biases said spring rod to an extended position;
wherein said cam follower that is engaged with said cam edge comprises one of: (i) said follower fastener; (ii) a roller, bushing, or slide member secured to said spring rod by said follower fastener.

### Claim 2 (depends on 1)

The receptacle as set forth in claim 1, wherein said latch base and said receptacle base are provided as a single one-piece construction.

### Claim 3 (depends on 1)

The receptacle as set forth in claim 1, wherein said latch base comprise a tab, and wherein said spring rod comprises a first end connected to said cam follower and a second end that extends through an aperture defined in said tab, said spring positioned coaxially about said spring rod between said tab and said cam follower.
