Two-stage adjustable door hinge
View Patent ↗A door hinge adapted to provide vertical and depth adjustments of an engaged door with a door frame. The hinge features a first hinge member adapted for fixed recessed engagement to a side edge of a door jam which is rotationally engaged with a support member extending from a second hinge member adapted for engagement to the door. Adjustment of height and depth of the door inside the door jam is easily achieved by rotation of adjustment screws accessible from a single surface that is visible when the second hinge member is engaged to the door.

said second hinge member adapted for, recessed engagement to the sidewall of a door;
a support member, said support member having a first end and having a second end;
means for rotatable engagement of said first hinge member to said first end of said support member;
means for translatable engagement in two substantially perpendicular directions, of said second end of said support member, within said cavity;
said second end of said support member translatable along a first axis running substantially parallel to said rear wall;
said second end of said support member translatable along a second axis, toward and away from said rearwall, along an axis 1 substantially normal to said first axis;
first means of adjustment of said second end to translate said second end of said support member to adjustably fixed positions along said first axis, between a starting position and an end position;
said first means of adjustment comprising:
a first adjustment pin having a first end in fixed engagement with said support member;
a second adjustment pin having a first end in fixed engagement with said second hinge member;
wherein the said first and second adjustment pins are axially aligned along the same axis;
a sleeve, said sleeve having a geared exterior wall and having a threaded axial passage running therethrough;
an adjustment screw rotationally mounted in said internal cavity having a center axis perpendicular to said axial passage and having a head portion adapted for tooled engagement through an aperture in said cover plate;
said adjustment screw having a geared exterior in an engagement with said geared exterior wall of said sleeve; and
said respective second ends of said first adjustment pin and said second adjustment pin, in a threaded engagement with said axial passage such that a rotation of said adjustment screw causes said first and second adjustment pins to move toward or away from each other to translate said support member along said first axis;
second means of adjustment of said second end to translate said second end of said support member to adjustably fixed points along said second axis, between a starting point and an end point; and
both said first means of adjustment and said second means of adjustment adapted for tooled engagement on respective engagement ends, said respective engagement ends both accessible through respective first and second apertures in said cover plate, whereby said door may be adjusted for fit within said jam along two axises with both said first and second means of adjustment, visible to said user when viewing said coverplate.
2. The adjustable door hinge of claim 1 wherein said means for translatable engagement in two substantially perpendicular directions, of said second end of said support member comprises:
four posts engaged at a first end to said rear wall and extending parallel to said second axis to distal ends terminating in said internal cavity;
four slots communicating through said support member in positions to engage said four posts, said slots being elongated and running along said first axis.
3. The adjustable door hinge of claim 1 additionally comprising:
said first aperture communicating through said cover plate being elongated and having sidewalls running a length between a first end to a second end;
said engagement end of said first means of adjustment adapted for slidable engagement within said first aperture between said sidewalls; and
said first end determining said starting position along said first axis and said second end of said first aperture determining said end position along said first axis.
4. The adjustable door hinge of claim 2 additionally comprising:
said first aperture communicating through said cover plate being elongated and having sidewalls running a length between a first end to a second end;
said engagement end of said first means of adjustment adapted for slidable engagement within said first aperture between said sidewalls; and
said first end determining said starting position along said first axis and said second end of said first aperture determining said end position along said first axis.
5. The adjustable door hinge of claim 1 wherein said second means of adjustment of said second end comprises:
an adjustment screw rotationally engaged within said internal cavity with engagement end within said internal cavity;
said adjustment screw having a threaded exterior surface; and
an aperture communicating through said support member having a sidewall adapted for threaded engagement with said exterior surface whereby rotation of said adjustment screw causes said support member to translate along said second axis.
6. The adjustable door hinge of claim 2 wherein said second means of adjustment of said second end comprises:
an adjustment screw rotationally engaged within said internal cavity with engagement end within said internal cavity;
said adjustment screw having a threaded exterior surface; and
an aperture communicating through said support member having a sidewall adapted for threaded engagement with said exterior surface whereby rotation of said adjustment screw causes said support member to translate along said second axis.
7. The adjustable door hinge of claim 3 wherein said second means of adjustment of said second end comprises:
an adjustment screw rotationally engaged within said internal cavity with engagement end within said internal cavity;
said adjustment screw having a threaded exterior surface; and
an aperture communicating through said support member having a sidewall adapted for threaded engagement with said exterior surface whereby rotation of said adjustment screw causes said support member to translate along said second axis.
8. The adjustable door hinge of claim 4 wherein said second means of adjustment of said second end comprises:
an adjustment screw rotationally engaged within said internal cavity with engagement end within said internal cavity;
said adjustment screw having a threaded exterior surface; and
an aperture communicating through said support member having a sidewall adapted for threaded engagement with said exterior surface whereby rotation of said adjustment screw causes said support member to translate along said second axis.
9. The adjustable door hinge of claim 1 additionally comprising:
said geared exterior of said adjustment screw in said engagement with said seared exterior wall of said sleeve providing means to prevent rotation of said sleeve, and resulting unintended changes in said fixed positions of said support member along said first axis.
10. An adjustable door hinge, comprising:
a first hinge member;
a second hinge member, comprising:
a support member pivotally engaged along a first direction to the first hinge member, the support member defining a slot;
a housing defining a recess;
a sleeve having a threaded internal passage along the first direction and a geared exterior;
an adjustment screw aligned along a second direction perpendicular to the sleeve, the adjustment screw having a geared exterior engaged with the geared exterior of the sleeve;
an upper adjustment pin having an upper end received in the recess of the housing and a threaded lower end received in the passage of the sleeve; and
a lower adjustment pin having a lower end received in the slot of the support member and a threaded upper end received in the passage of the sleeve; and
wherein a rotation of the adjustment screw rotates the sleeve to move the upper and the lower adjustment pins toward or away from each other along the first direction, thereby moving the support member along the first direction.
11. The adjustable door hinge of claim 10 , further comprising:
an other adjustment screw aligned along the second direction; and
wherein the support member defines a threaded aperture for receiving the other adjustment screw, and a rotation of the other adjustment screw moves the support member along the second direction.
