Flag stop door hinge

Abstract

A hinge (FIG. 1) with an adjustable built-in door stop mechanism. The hinge contains two leaves and a hinge pin. The first leaf with three knuckles has various receptacles (4) on both the upper and lower knuckles (3) to ensure the door stop works with both right and left-handed doors. The hinge also contains a standard hinge pin (5) that includes a flag (6) immediately at the base of the pin head. The hinge is designed to stop when the pin flag (6) is inserted into one of the pin flag receptacles (4) limiting the swing range of motion of the hinge. The second leaf (2) will rotate until making contact with the pin flag (6) and the top knuckle (3), stopping the hinge from rotating any further. The appropriate pin flag receptacle (4) selected is based on the required swing of the hinge.

Claims

1. Leaf one (1) contains three knuckles (3), with the upper and lower knuckles to include pre-set pin flag receptacles (4) that are set to limit leaf range of motion to predetermined angles of hinge rotation, most commonly 90 and 180 degrees of rotation. Knuckles may include multiple receptacles and the location of receptacles may vary depending on the proximity of the door to the required range of motion of the hinge.

2. Upper and lower knuckles (3) of the first leaf both include flag receptacles (4) to allow for the same hinge to be utilized on right and left-handed doors.

3. Hinge pin (5) contains a pin flag (6) immediately below the pin head that will be inserted into the flag receptacle (4). The pin flag may be of varying shapes and sizes to adjust the swing of the door or to add style or safety features to the flag.

4. First leaf (1) should be attached to door frame, second leaf (2) should be attached to the door to allow the second leaf to swing freely, coming into contact with the pin flag (6), stopping the door.

5. Pin flag (6) inserts into appropriate upper knuckle flag receptacle (4) with the pin flag (6) limiting the range of motion for the second leaf (2) to swing.

6. The upper section of the second leaf (2) will make contact with the pin flag (6), stopping the motion of the hinge and door.

7. The Flag Stop Door Hinge is utilized on all three door hinges to evenly distribute the load throughout the door jam. This distribution prohibits damage to the door, jam, wall or hinge.

Description

DESCRIPTIONS OF DRAWING

[0010] The Flag Stop Door Hinge is shown in three pieces (FIG. 1), fully assembled (FIG. 2) and as viewed from above (FIG. 3) with various stops utilized to limit range of motion to 90 degrees and 180 degrees of door range of motion. [0011] 1. Leaf onecontains three knuckles (3) and four holes for screw placement to allow the leaf to be attached to the door jam. This leaf must be attached to the door jam and not to the door to ensure sufficient range of motion and a stationary pin flag (6). [0012] 2. Leaf twocontains two knuckles and four holes for screw placement in the door. This leaf must be attached to the door itself and not to the door jam. This allows leaf two to rotate freely on the hinge pin (5). [0013] 3. Upper and lower knucklescontains two pin flag receptacles (4) to allow the user to select the appropriate range of motion depending on the location of the door and the proximity to the wall. The upper and lower knuckles must be attached to the door jam as stated above. [0014] 4. Pin flag receptaclesare slots placed in the upper and lower knuckles (3) of each hinge. The receptacles are specifically located to allow for easy pin flag (6) placement that limits the range of motion of the hinge to the desired amount. The most common application is at 90 degree and 180 degree range of motion for the door. Custom hinges receptacles can be developed to allow for varying ranges of motion. [0015] 5. Hinge pinutilized to join together leaf one (1) and leaf two (2) allowing a 360 degree range of motion when left free. The hinge pin contains a pin flag (6) that limits the range of motion of the hinge to a desired amount when placed in a flag receptacle (4). [0016] 6. Pin flagattached to the hinge pin (5) at the base of the pin head. Utilized to stop the range of motion of the free swinging door when placed in a flag receptacle (4). The hinge pin (5) and pin flag are manufactured by the same materials and are one piece. The hinge pin (5) and pin flag do not come apart.
