BREAKAWAY HINGE RECEPTACLE
First Claim
1. A breakaway hinge receptacle comprising:
- a base including first and second hinge arm mounting structures, said second hinge arm mounting structure movable between an operative position and a breakaway position;
a breakaway lever connected to the base and including inner and outer ends, wherein said inner end is operatively engaged with said second hinge arm mounting structure;
a spring operatively engaged between said breakaway lever and said base, said spring biasing said breakaway lever to a first position in which said inner end of said breakaway lever biases said second mounting structure to its operative position;
wherein said second hinge arm mounting structure is selectively movable from its operative position to its breakaway position against said biasing force exerted by said inner end of said breakaway lever and said spring.

Abstract
A breakaway hinge receptacle includes a base including first and second hinge arm mounting structures. The second hinge arm mounting structure is movable between an operative position and a breakaway position. A breakaway lever is connected to the base and includes inner and outer ends, wherein the inner end is operatively engaged with the second hinge arm mounting structure. A spring is operatively engaged between the breakaway lever and the base. The spring biases the breakaway lever to a first position in which the inner end of the breakaway lever biases the second mounting structure to its operative position. The second hinge arm mounting structure is selectively movable from its operative position to its breakaway position against the biasing force exerted by the inner end of said breakaway lever and the spring. Alternatively, the second hinge arm mounting structure is defined by or is connected to or is otherwise included on the inner end of the breakaway lever.
