Abstract

An adjustable hinge of the present invention includes a hinge pin and a hinge plate coupled to the hinge pin and a plurality of adjusters configured to threadedly engage a plurality of threaded apertures formed in the hinge plate. The adjusters define respective central pass-through bores for receiving a fastener configured to fasten the hinge plate to a door or door frame. The adjusters are operatively associated with a door or door frame, so that, after slightly loosening the existing fastener, rotating the adjuster changes the gap between the hinge plate and the surface of the door or door frame. Once the desired gap has been obtained, the fastener is tightened against the adjuster, and into the door or door frame, thereby maintaining the gap.

First claim

What is claimed is:

1. A hinge, comprising:
a hinge pin;
a hinge plate coupled to the hinge pin;
the hinge plate defining a plurality of threaded apertures;
a plurality of adjusters configured to threadedly engage a respective one of the plurality of threaded apertures; and
each of the plurality of adjusters defining a central pass-through bore for receiving a respective fastener configured to fasten the hinge plate to a door or a door frame, each adjuster includes an annular body defining a longitudinal axis, the pass-through bore having a first diameter and a second diameter, the second diameter being smaller than the first diameter and positioned between the first diameter and a rear face of the annular body, such that the pass-through bore forms a truncated cone.

2. The hinge claimed in claim 1 , wherein:
the annular body further defining an annular rear face engageable with said door or door frame, and an annular front face;
the front face and the rear face lie in respective planes substantially perpendicular to the longitudinal axis; and wherein
the pass-through bore being unthreaded.

3. The hinge claimed in claim 2 , wherein each adjuster defines a tool-engaging feature configured for engagement by a tool for rotating the adjuster in its respective threaded aperture.

4. The hinge claimed in claim 3 , wherein the tool-engaging feature is defined by two radially-opposed axial slots formed in each front face.

5. The hinge claimed in claim 2 , wherein:
the annular body defining a first outer diameter;
the front face is defined by an annular shoulder having a second outer diameter greater than the first outer diameter;
the annular shoulder defining an internal chamfer;
the internal chamfer tapering radially inwardly to a cylindrical bore; and wherein the hinge plate defining a chamfer engageable by the annular shoulder.

6. The hinge claimed in claim 1 , wherein:
the adjuster defining a longitudinal axis;
the hinge plate defining an annular shoulder proximate the threaded aperture;
the adjuster including first and second members defining respective bores coaxial with the longitudinal axis;
one of the first and second members including an outer surface configured to threadedly engage the hinge plate threaded aperture;
the first and second members being configured to be threadedly engageable with one another, so as to be advanced or retracted in the hinge plate threaded aperture as a single unit; and wherein
at least one of the first and second members being configured to engage the hinge plate shoulder to limit the amount of axial travel of the first and second members in the hinge plate threaded aperture.

7. The hinge claimed in claim 6 , further comprising an anti-rotation member coaxial with the longitudinal axis, and disposed within respective portions of the first and second members, for preventing relative rotation between the first and second members.

8. The hinge claimed in claim 1 , wherein:
the adjuster including two annular members defining respective annular shoulders;
the annular members further defining respective pass-through bores coaxially aligned along a longitudinal axis;
one of the annular members including a threaded cylindrical wall threadedly engageable with the threaded aperture of the hinge plate;
the other of the annular members being connected to the one annular member so that the annular members may be advanced or retracted as a unit in the hinge plate threaded aperture, whereby the respective shoulders of the two annular members are configured to engage the hinge plate to limit the amount of travel that the adjuster can make within the hinge plate; and wherein
one of the annular members defining an anti-rotation member and the other of the annular members defining a recess configured to accept the anti-rotation member.

9. The hinge claimed in claim 8 , wherein the anti-rotation member has a cross-section which is any one of a rectangular, a triangular, and a circular cross-section.

10. The hinge claimed in claim 8 , wherein the adjuster further defining a tool-engaging feature configured for engagement by a tool for rotating the adjuster in its respective threaded aperture.

11. The hinge claimed in claim 1 , wherein:
the hinge plate defining a first hinge plate; and further comprising:
a second hinge plate coupled to the hinge pin; wherein
the second hinge plate defining a plurality of apertures, each configured for receiving a fastener configured to fasten the second hinge plate to a door frame or door.

12. The hinge claimed in claim 11 , wherein the plurality of apertures defined by the second hinge plate are threaded for receiving said adjusters.

13. The hinge claimed in claim 1 , wherein the adjusters are operatively associated with the surface of the frame or door to change the distance between the hinge plate and the surface of the frame or door.

14. A door system, comprising:
a door pivotably connected to a door frame via a plurality of hinges;
the hinges including first and second hinge plates coupled to a hinge pin; wherein at least one of said first and second hinge plates defining a plurality of threaded apertures; and further comprising:
a plurality of annular threaded adjusters engaged with respective threaded apertures and configured to selectively axially bear against a surface of said door or door frame to change the distance between the at least one of said first and second hinge plates and a surface of the door or door frame; wherein,
the adjusters further defining respective central pass-through bores for receiving a fastener; and further comprising:
a fastener disposed in each pass-through bore and configured to fasten said hinge plate to said door or door frame.

15. The door system claimed in claim 14 , wherein:
each adjuster including an annular body defining a longitudinal axis;
the annular body further defining an annular rear face engageable with said door or door frame and an annular front face, the front and rear faces lying in planes substantially normal to the longitudinal axis; and wherein
the pass-through bores being unthreaded, and having a first diameter proximate the front face and a second diameter proximate the rear face, the second diameter being smaller than the first diameter, such that the pass-through bore tapers radially inwardly towards the rear face.

16. The door system claimed in claim 15 , wherein:
the adjuster further defining a longitudinal axis;
said at least one hinge plate defining an annular shoulder proximate the threaded aperture;
the adjuster including first and second members defining respective pass-through bores coaxial with the longitudinal axis;
one of the first and second members including an outer surface configured to threadedly engage the hinge plate threaded aperture;
the first and second members being configured to be threadedly engageable with one another, so as to be advanced or retracted in the hinge plate threaded aperture as a single unit; wherein
at least one of the first and second members being configured to engage the hinge plate shoulder to limit the amount of axial travel of the first and second members in the hinge plate threaded aperture; and further comprising:
an anti-rotation member coaxial with the longitudinal axis, and operatively associated with the first and second members, for preventing relative rotation between the first and second members.

17. The door system claimed in claim 16 , wherein:
the front face of the adjuster defining two radially-opposed tool-receiving slots axially formed in the fron
