Abstract
Door hinges are disclosed that are configured to allow operators to hold a door in an open position at specific and desired angles (and for such specific and desired angles to be easily and quickly modulated by an operator). In addition, the door hinges are configured to allow an operator to easily and quickly establish a maximum angle by which the hinge—and its attached door—are allowed to be opened, i.e., how wide the hinge and door are allowed to open (which also may be easily and quickly modulated by an operator).
Claims12
A door hinge assembly that comprises:
- (a) a first leaf having a first knuckle and a second knuckle;
- (b) a second leaf having a third knuckle and a fourth knuckle;
- and
- (c) a pin, wherein:
- (i) the first leaf and second leaf are configured to be combined by aligning the first knuckle on top of the third knuckle, aligning the third knuckle on top of the second knuckle, and aligning the second knuckle on top of the fourth knuckle;
- and
- (ii) the pin is configured to be inserted into a contiguous channel that is formed when the first knuckle, second knuckle, third knuckle, and fourth knuckle are combined and aligned with each other, wherein the door hinge assembly is configured (A) to be held in an open position at any of a plurality of specific and adjustable angles and, separately and simultaneously, (B) to have a maximum angle by which the door hinge can be opened, wherein said maximum angle may be adjusted by an operator and said maximum angle may optionally represent an angle that differs from the specific and adjustable angles of (c)(ii)(A) above, wherein (y) the first knuckle of the first leaf comprises a first set of teeth located on a bottom surface of the first knuckle that are oriented and configured to face a second set of teeth located on a top surface of the third knuckle of the second leaf;
- and (z) upon adjoining the first set of teeth to the second set of teeth a plurality of slots are formed between adjoined teeth of the first set of teeth and second set of teeth, wherein the plurality of slots are configured to reversibly receive a peg, whereupon insertion of said peg into one of the slots prohibits rotation of the first knuckle and third knuckle about an axis formed by the pin.
