Abstract
A universal hinge structure includes a hinge part attachable to a frame and another hinge part attachable to a pivotable closure which is to be mounted in the frame. At least one of the hinge parts includes a cylindrical body having an adjustment screw extending therethrough and protruding into either the frame or the closure member. The adjustment screw is restrained by a locking pin so that it can not move axially relative to the body. The adjustment screws is threaded so that rotation of the screw in the frame or movable member adjusts the pivot axis of the hinge structure relative to the frame. Embodiments for various frame and closure member materials are disclosed.
Claims12
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.
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.
