Abstract
A hinge assembly with reinforced abutment surfaces via the use of multiple strike plates. The strike plates are made from stronger and more robust materials than the underlying hinge, such that the strike plates bear the loads (vs. the underlying hinge material) to prevent deformation of the hinge components during use over time.
Claims20
A hinge assembly with reinforced abutments, comprising:
- an upper hinge member, a lower hinge member, and a middle hinge member hingedly coupled between said upper hinge member and said lower hinge member via a first connecting pin linking the upper hinge member to the middle hinge member and a second connecting pin linking the lower hinge member to the middle hinge member such that said hinge assembly is configured to be positioned into a straightened state and a folded state;
- the upper hinge member having an upper surface, a first recess formed along a first end of said upper surface, and at least one connecting pin bore dimensioned to receive said first connecting pin;
- the lower hinge member having an upper surface, a second recess formed along a first end of said upper surface, and at least one connecting pin bore dimensioned to receive said second connecting pin;
- the middle hinge member having an upper surface, a third recess formed along a first end of said upper surface, a fourth recess formed along a second end of said upper surface, at least one connecting bore dimensioned to receive said first connecting pin, and at least one connecting bore dimensioned to receive said second connecting pin;
- a first abutment joint formed between an abutment surface of a first strike plate mounted within said first recess of said upper hinge member and an abutment surface of a third strike plate mounted within said third recess of said middle hinge member when said upper hinge member and said middle hinge member are in said straightened state with said upper surface of said upper hinge member generally co-planar with said upper surface of said middle hinge member;
- and
- a second abutment joint formed between an abutment surface of a second strike plate mounted within said second recess of said lower hinge member and an abutment surface of a fourth strike plate mounted within said fourth recess of said middle hinge member when said lower hinge member and said middle hinge member are in said straightened state with said upper surface of said lower hinge member generally co-planar with said upper surface of said middle hinge member;
- wherein said first abutment joint is configured to be selectively opened by rotating said upper hinge member relative to said middle hinge member and said second abutment joint is configured to be selectively opened by rotating said lower hinge member relative to said middle hinge member when said upper hinge member, said lower hinge member, and said middle hinge member are positioned into said folded state.

A hinge assembly with reinforced abutments, comprising:
- an upper hinge member, a middle hinge member, a lower hinge member, a first connecting pin for coupling said upper hinge member to said middle hinge member, and a second connecting pin for coupling said middle hinge member to said lower hinge member such that said hinge assembly is configured to be positioned into a straightened state and a folded state;
- said upper hinge member having a generally flat upper surface and a first strike plate mounted within a recess formed along a first end of said upper surface, wherein said first strike plate has an abutment surface that is generally perpendicular to said upper surface and extends a majority of a width of said upper hinge member;
- said lower hinge member having a generally flat upper surface and a second strike plate mounted within a recess formed along a first end of said upper surface, wherein said second strike plate has an abutment surface that is generally perpendicular to said upper surface and extends a majority of a width of said lower hinge member;
- said middle hinge member having a generally flat upper surface, a third strike plate mounted within a recess formed along a first end of said upper surface, a fourth strike plate mounted within a recess formed along a second end of said upper surface, wherein each of said third strike plate and said fourth strike plate has an abutment surface that is generally perpendicular to said upper surface and extends a majority of a width of said middle hinge member;
- wherein a first abutment joint is formed between said abutment surface of said first strike plate and said abutment surface of said third strike plate when said upper hinge member and said middle hinge member are in said straightened state with said upper surface of said upper hinge member generally co-planar with said upper surface of said middle hinge member;
- wherein a second abutment joint is formed between said abutment surface of said second strike plate and said abutment surface of said fourth strike plate when said lower hinge member and said middle hinge member are in said straightened state with said upper surface of said lower hinge member generally co-planar with said upper surface of said middle hinge member;
- and
- wherein said first abutment joint is configured to be selectively opened by rotating said upper hinge member relative to said middle hinge member and said second abutment joint is configured to be selectively opened by rotating said lower hinge member relative to said middle hinge member when said upper hinge member, said middle hinge member, and said lower hinge member are positioned into said folded state.
