Abstract

A split hinge made of a first hinge portion having a first cover that is operatively coupled to two first leaves, and a second hinge portion having a second cover that is operatively coupled to two second leaves. The first leaves, the second leaves, the first cover, and/or the second cover may have the same or different lengths. The first leaves may have first leaf lengths that are greater than or less than the first cover, while the second leaves may have second leaf lengths that are greater than or less than the second cover. The first cover may extend over the first leaves, the second cover may extend over the second leaves, and a portion of the first cover may extend over a portion of the second leaves or a portion of the second cover may extend over a portion of the first leaves to form the split hinge.

Claims (40)

1 . A method of installing a modular door hinge to a door system, the method comprising:

assembling a first hinge portion to a second hinge portion using a first cover, wherein the first hinge portion comprises:

two first leaves, each of the two first leaves comprising:

a first web; and

a first head with first teeth extending from the first web; and

the first cover operatively coupled to the two first leaves;

wherein the first cover has a first cover length that is greater than a first hinge length of the first hinge portion; and

wherein the second hinge portion comprises:

two second leaves, each of the two second leaves comprising:

a second web; and

a second head with second teeth extending from the second web; and

a second cover operatively coupled to the two second leaves;

wherein the second cover has a second cover length that is less than a second hinge length of the second hinge portion; and

wherein the first hinge portion is operatively coupled to the second hinge portion by operatively coupling a portion of the first cover to the two second leaves such that the portion of the first cover extends over the second head of each of the two second leaves;

assembling one of the two first leaves and one of the two second leaves to a door frame; and

assembling another of the two first leaves and another of the two second leaves to a door, wherein after assembling the two first leaves and the two second leaves to the door frame and the door the modular door hinge is installed such that the first cover and the second cover are exposed.

2 . The method of claim 1 , wherein the two first leaves have first leaf lengths and the two second leaves have second leaf lengths.

3 . The method of claim 2 , wherein the first leaf lengths are greater than the second leaf lengths.

4 . The method of claim 2 , wherein the first leaf lengths are less than the second leaf lengths.

5 . The method of claim 2 , wherein the first leaf lengths are equal to the second leaf lengths.

6 . The method of claim 1 , wherein a first web length of the first web is less than a first head length of the first head, and a second web length of the second web is greater than a second head length of the second head.

7 . The method of claim 1 , wherein a first web length of the first web is greater than a first head length of the first head, and a second web length of the second web is less than a second head length of the second head.

8 . The method of claim 1 , wherein the first cover length is greater than the second cover length.

9 . The method of claim 1 , wherein the second cover length is greater than the first cover length.

10 . The method of claim 1 , wherein the first cover length is equal to the second cover length.

11 . The method of claim 1 , wherein the first hinge length and the second hinge length are less than or equal to 48 inches to allow for packaging within a package having a length less than or equal to 48 inches.

12 . The method of claim 1 , wherein the first hinge portion and the second hinge portion form the modular door hinge having a door hinge length of 83 inches.

13 . The method of claim 1 , further comprising:

assembling an extension hinge portion to the first hinge portion or the second hinge portion using an extension cover, wherein the extension hinge portion, comprising:

two extension leaves, each of the two extension leaves comprising:

an extension web; and

an extension head extending from the extension web and having a longitudinal axis; and

the extension cover operatively coupled to the two first leaves.

14 . The method of claim 13 , wherein the extension hinge portion has an extension hinge length of 12 inches.

15 . The method of claim 13 , wherein the first hinge length, the second hinge length, and an extension hinge length form the modular door hinge having a door hinge length of 95 inches.

16 . The method of claim 13 , wherein the extension cover has an extension cover length that is equal to an extension hinge length of the extension hinge portion.

17 . The method of claim 13 , wherein the extension cover has an extension cover length that is greater than an extension hinge length of the extension hinge portion.

18 . The method of claim 13 , wherein the extension cover has an extension cover length that is less than an extension hinge length of the extension hinge portion.

19 . The method of claim 13 , wherein the first hinge portion and the second hinge portion are coupled to each other only through the first cover.

20 . The method of claim 13 , wherein the extension portion is assembled between the first hinge portion and the second hinge portion.
