Claims
- 1. An adjustable hinge for pivotably supporting a movable closure on a frame such that the pivot axis of the closure member is adjustable relative to the frame during and after installation, comprising the combination of
- a first hinge element including a first hinge body having a central axis with an axially extending pin coaxial with said central axis and first means for attaching said first hinge body to the frame; and
- a second hinge element including a second hinge body having an axial passage extending therethrough for receiving said pin in one end thereof so that said second hinge body is rotatably and coaxially supported on said axially extending pin and so that said hinge bodies have a common central axis and second means for attaching said second hinge body to the movable closure member,
- said axial passage having means defining internal threads extending substantially symmetrically on opposite sides of a central transverse plane perpendicular to said central axis;
- an externally threaded support bolt extending into the opposite end of said axial passage from said pin;
- a ball between the inner ends of said pin and said threaded support bolt so that said hinge elements are relatively pivotable about said central axis and are relatively axially adjustable by rotation of said support bolt, said support bolt being selectively threadable into either end of said axial passage so that said first hinge element can be mounted on either side of a frame with said support bolt above said pin;
- one of said first and second means for attaching including
- an adjustment bolt extending rotatably completely through one of said first and second hinge bodies, said adjustment bolt having a threaded end portion extending into the associated one of said frame and said movable closure member,
- means defining threads in said one of said frame and movable closure member for threadedly engaging said adjustment bolt,
- means for restraining said adjustment bolt against axial movement in either direction relative to said one of said first and second hinge bodies so that rotation of said adjustment bolt about its longitudinal axis moves said central axis of said hinge elements toward or away from said one of said frame and said movable closure member, and
- guide bolt means carried by said one of said first and second hinge bodies and extending parallel with said adjustment bolt and being slidable into said one of said frame and said movable closure member for preventing rotation of said one of said first and second hinge bodies about said longitudinal axis of said adjustment bolt when said adjustment bolt is rotated,
- the other of said first and second means for attaching including means for adjusting the location of said central axis of said hinge elements relative to the other of said frame and said movable closure member.
- 2. An adjustable hinge according to claim 1 wherein said means for axially restraining said adjustment bolt includes
- an annular recess in said adjustment bolt within the hinge body through which said adjustment bolt extends, and
- a locking pin extending into said hinge body generally perpendicular to said adjustment bolt and lying in said annular recess.
- 3. An adjustable hinge according to claim 2 wherein said first hinge body is generally cylindrical and said adjustment bolt and said guide bolt means pass through said central axis of said body.
- 4. An adjustable hinge according to claim 1 wherein the other of said first and second means for attaching includes
- a bracket attached to the other hinge body, said bracket having a plurality of openings therethrough
- first threaded means extending into and threadedly engaging the associated one of said frame and said movable closure member, said first threaded means passing through at least one of said openings in said bracket and having an enlargement for urging said bracket toward said associated one of said frame and said movable closure member; and
- second threaded means extending into and threadedly engaging the associated one of said frame and said movable closure member, said second threaded means abutting said bracket to limit the motion of said bracket toward the associated one of said frame and said movable closure member.
- 5. An adjustable hinge according to claim 4 and further including an internally threaded sleeve extending into said one of said frame and said movable closure member for receiving said theaded end portion of said adjustment bolt.
- 6. An adjustable hinge according to claim 5 wherein said adjustment bolt includes an outer exposed end having a non-circular recess for receiving an adjustment tool.
- 7. An adjustable hinge for pivotably supporting a movable closure on a frame such that the pivot axis of the hinge is adjustable relative to at least one of the closure and frame during and after installation comprising the combination of
- a first hinge element including a first hinge body having
- a central axis,
- an axially extending pin coaxial with said central axis and
- first means for attaching said first hinge body to the frame;
- a second hinge element including a second hinge body having
- an axial passage extending through said second hinge body for receiving said axially extending pin in one end thereof so that said hinge bodies have a common central axis,
- second means for attaching said second hinge body to the movable closure member, and
- means in said axial passage defining internal threads extending substantially equal distances in both directions axially away from a central transverse plane perpendicular to said central axis;
- an externally threaded support bolt extending into the opposite end of said axial passage from said pin and threadedly engaging said internal threads, said support bolt being selectively threadable into either end of said axial passage so that said first hinge element can be mounted on either side of a frame with said support bolt above said pin;
- a friction-reducing ball between the inner, distal ends of said pin and said threaded support bolt so that said second hinge body is rotatably supported through said support bolt on said pin, the axial position of said second hinge body relative to said first hinge body being adjustable by rotation of said support bolt to adjust the axial position thereof in said axial passage; and
- at least one of said first and second means for attaching including adjustable means for changing the distance between said central axis of the respective one of said first and second hinge elements and one of said frame and said closure member.
- 8. An adjustable hinge according to claim 7 wherein said adjustable means for changing the distance comprises
- an adjustment block;
- block screws for attaching said adjustment block to one of said frame and said closure member;
- a hinge plate fixedly attached to one of said first and second hinge bodies and having first and second surfaces generally parallel with said adjustment block
- adjustment screws threadedly engaging said adjustment block and abutting said first surface of said hinge plate facing said block for establishing a distance between said first surface and said block;
- locking screws extending through said plate and threadedly engaging said block, said locking screws having enlarged heads for engaging the second surface of said plate and holding said plate against said adjustment screws; and means defining openings through said plate to permit access to said adjustment screws for adjustment thereof.
- 9. An adjustable hinge according to claim 8 wherein said adjustable means including said hinge plate and block is formed symmetrically with respect to said central transverse plane.
- 10. An adjustable hinge according to claim 9 and further including internally threaded sleeves mounted in said one of said frame and said closure member for receiving said block screws, said sleeves being formed as blind rivets.
- 11. An adjustable hinge according to claim 10 wherein all of said screws are formed with heads to receive the same adjusting tool.
- 12. An adjustable hinge according to claim 11 wherein said heads of said screws for formed with hexagonal sockets.
