DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Referring to the drawing, wherein like numerals represent like parts throughout the several views, there is generally disclosed at 10 an adjustable hinge. The adjustable hinge 10 includes a frame leaf 11 having three mounting holes 11a formed therein. The mounting holes have a countersunk construction on surface 11c. The mounting holes 11a are used to secure the frame leaf 11 to a frame 80. The frame leaf 11 is generally planar and suitable mounting screws 20 or other mounting mechanisms are utilized, as is well known in the art. The frame leaf 11 has two spaced knuckles 12 that are operatively connected to the leaf frame 11. The spaced knuckles 12 mate with a knuckle 13 on a door leaf 14. End cap 12a may be provided to provide a finished look to the knuckle 12. The end cap 12a is optionally threaded so that it may be screwed into the knuckle. A bore extends through the knuckles 12 and 13 and the leaves 11 and 14 are engaged together with a pivot pin 25 which enables the leaves 11, 14 to pivot with respect to each other.

The frame leaf 11 has two generally planar surfaces 11b and 11c. The thickness of the frame leaf 11 is such that it matches with the thickness of a notch, or continuous groove, formed in the frame 80 when mounted, which is well known in the art.

The door leaf 14 has two mounting holes 14a. The mounting holes 14a are generally oblong and have a countersunk construction on the generally planar surface 14b. As can be seen best in FIG. 3, the mounting holes 14a are generally oblong to allow for movement of mounting screws 15, as will be described more fully hereafter.

The mounting screws 15 have a generally circular shaft 15a. The surface 14c, which is on the opposite side of the door leaf 14 from surface 14b is not planar. There are several features that are defined in the door leaf 14 as will be described more fully hereafter. The door leaf 14 and frame leaf 11 are preferably formed by extrusion and are constructed from aluminum, although other suitable materials and construction techniques may also be utilized. However, the extrusion process is advantageous for defining the features of the door leaf 14. The door leaf 14 includes a capturing member 16. The capturing member 16 includes a first angled side wall 17 and a second angled side wall 18. The side walls 17 and 18 extend away from the surface 14c such that proximate the surface 14c they are spaced further apart than they are away from the surface 14c. The distance X is greater than the distance Y. Further, the distance X is larger than they width of the head 19a of an adjustment screw 19. However, the distance Y is less than the width of the head 19a and greater than the diameter of the shaft 19b. Accordingly, the head 19a may be captured in the capturing member 16. The capturing member 16 has a first opening 16a and a second opening 16b. The head 19a of the adjustment screw 19 may be slid into either opening 16a or 16b, thereby placing the adjustment screw head 19a into the slot defined between the side wall 17 and 18 and the surface 14c. The surface 14c, as seen in FIG. 4, is irregular, and not planar like the surface 14d. The portion of the surface 14c that is between the side walls 17 and 18 has a raised portion 14d. The side walls 17 and 18 and the raised portion 14d are extruded and run the length of the door leaf 14.

An adjustment hole 14e is formed in the door leaf 14. The adjustment hole 14e is positioned in the slot defined by the sidewalls 17 and 18. Further, the adjustment hole 14e is centrally located through the raised portion 14d. The raised portion 14d extends up to the adjustment hole 14e on both sides of the hole 14e, so that the head 19a of the adjustment screw 19 will be positioned on top of the raised portion 14d. A covering flange 14f extends generally perpendicular to the bottom surface 14c and runs along an inner edge of the door leaf 14. The inner edge is proximate the rotatable connection formed by the knuckles 12 and 13. This covering flange provides for a visual barrier to make it more difficult for a person to see between the knuckles 12 and 13 and the door leaf 14. This provides for a more aesthetic appearance.

An edge flange 14g extends generally parallel to the top surface 14b and away from the sides 17 and 18. As will be described more fully hereafter, the width of the edge flange 14g is designed so that the edge flange 14g will bottom out, or contact the door, when at a maximum gap.

In the embodiment shown, the frame leaf 11 is mounted to a frame 80 by mounting screws 20. The door leaf 14 is mounted to a door 35. The planar surface 14c is mounted adjacent the door 35. While the features shown on the surface 14c are shown on the door leaf 14, it is understood that the features could instead be applied to the frame leaf 11. However, the installation will be described in FIGS. 6-8 where the features are applied to the door leaf 14.

In FIG. 6, the installation of the adjustable hinge 10 is shown with a nominal gap between the door 35 and frame 80. The frame leaf 11 is secured to the frame 80, as previously described. Then, the head 19a of an adjustment screw 19 is slid into the slot defined by the side walls 17 and 18. The head 19a can enter the slot either through opening 16a or 16b. The adjusting screw 19 is then captured by the capturing member 16. The door leaf 14 is secured to the door 35 by screws 15. Adjustment screw 19 is also screwed into the door 35. A screwdriver, or suitable driving tool, is inserted through the opening 14e and the screw is rotated to drive into the door 35. Indicia 40 is positioned on the surface 14b. The indicia 40 is a + and a − with a two-headed arrow. This indicated turning to the right increases the gap and turning to the left decreases the gap. As viewed in FIG. 3, continual rotation will lead to a larger gap and less rotation will yield a smaller gap. FIG. 7 shows a minimum gap. There, the adjustment screw 19 has been rotated counterclockwise from the position shown in FIG. 6. Since the mounting screws 15 are not being moved in or out, the counterclockwise rotation of the adjustment screw 19 will cause the door leaf 14 to pivot closer to the frame leaf 11. This will close the gap between the door 35 and frame 80. In doing so, the head 19a of the adjustment screw 19 pivots on the raised portion 14d, which acts to stabilize the screw 19. Since the screws 15 do not move in the door 35, the oblong holes provide for a clearance as the door leaf 14 is pivoted. The surface 14c contacts the door 35 at point A, at the same time that the edge flange 14g is contacting the frame leaf 11. That is, they bottom out at the same time.

FIG. 8 shows the adjustable hinge 10 adjust for a maximum gap. There, as viewed in FIG. 3, the adjustment screw 19 would be rotated to the right. This causes the door leaf 14 to pivot away from the frame leaf 11, thereby increasing the gap between the door 35 and frame 80. The edge flange 14g is sized to contact the door 35 at the point where the screw head 19a is contacting the side wall 18 and the surface 14c, thus these three are bottoming out at the same time.

Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
