## Abstract

A butt mounting hinge capable of movement through at least a 270-degree range of motion. The hinge assembly has two base elements and three connection elements defining a total of five hinge connections. The base elements are butt mounting elements. Each base element provides two pair of hinge connections, while the fifth hinge connection rides in a slidable void provided by an intermediate connection element interconnecting the other two connection elements.

## Claims

### Claim 1

A hinge assembly, comprising:
a first mounting plate;
a second mounting plate; and
a linkage interconnecting the first and second mounting plates so that the first and second mounting plates are pivotable relative to each other by at least 270-degrees.

### Claim 2 (depends on 1)

The hinge assembly of claim 1, further comprising:
the linkage comprises a first, a second, and a third connection element, respectively, wherein each connection element has a first end and a second end, and wherein the first end and the second end each have a pair of connection points;
a slidable void extending between the first and the second ends of the second connection element; and
the second end of the first connection element and the first end of the third connection element form a ridable hinge connection along said slidable void.

### Claim 3 (depends on 2)

The hinge assembly of claim 2, wherein the first and second mounting plates are pivotable relative each other between a first state and a second state, wherein the first state, the first and second mounting plates are coplanar and wherein in the second state, the first and second mounting plates are oriented at least 270-degrees relative to each other.

### Claim 4 (depends on 3)

The hinge assembly of claim 3, wherein the first state the ridable hinge is at a first end of the slidable void, and wherein the second state the ridable hinge is at a second end of the slidable void.

### Claim 5 (depends on 4)

The hinge assembly of claim 4, further comprising:
each mounting plate has a first and a second connecting portion, each connecting portion is pivotably connectable to one of a pair of connection elements; and
the first connecting portion of the first mounting plate and the first end of the first connection element form a first hinge connection.

### Claim 6 (depends on 5)

The hinge assembly of claim 5, further comprising:
the first connecting portion of the second mounting plate and the second end of the second connection element form a second hinge connection.

### Claim 7 (depends on 6)

The hinge assembly of claim 6, further comprising:
the second connecting portion of the first mounting plate and the first end of the second connection element form a third hinge connection.

### Claim 8 (depends on 7)

The hinge assembly of claim 7, further comprising:
the second connecting portion of the second mounting plate and the second end of the third connection element form a fourth hinge connection.

### Claim 9 (depends on 8)

The hinge assembly of claim 8, further comprising:
the second end of the first connection element and the first end of the third connection element ride along the slidable voids of the second connection element to form a fifth hinge connection; wherein, between the first state and the second state, the first and third hinge connections rotate approximately 90-degrees and the second and fourth hinge connections rotate approximately 180-degrees and the fifth hinge connection rides along the said slidable voids.

### Claim 10 (depends on 9)

The hinge assembly of claim 9, wherein, for each mounting plate, the first and the second connecting portions are offset from each other in at least two directions.
