Description
BACKGROUND OF THE INVENTION
The present invention relates generally to an improved recessed
door hinge for mounting a door member on a supporting frame member
which enables horizontal and vertical adjustment of the mounted
door relative to the supporting frame member.
Adjustable recessed hinges are known in the art and generally
comprise a hinge cup which can be fixed in a bore of either a door
member or a supporting frame member, a separate mounting plate
fixed to the other of the door or supporting frame members, a
separate intermediate adjusting part or parts connectable to either
or both of the hinge cup and the mounting plate, and a hinge arm
interconnectable between intermediate adjusting parts or between an
intermediate adjusting part and either of the hinge cup or the
mounting plate.
In such devices, the hinge cup is dimensioned to snugly fit into
the bore, for example, of a door and is adapted to be secured
against displacement within the bore relative to the door and the
mounting plate is likewise adapted to be fixed, for example to a
supporting frame and secured against displacement relative to the
supporting frame. Adjustment or repositioning of the mounted door
relative to the supporting frame is provided by one or more
separate intermediate adjusting parts which include arrangements of
plates, blocks and the like that are slidable in grooves, channels
or the like and clamped, for example, with one or more set
screws.
Such prior art devices are expensive and difficult to make in that
such devices require the fabrication and handling of many parts,
including a hinge cup, a hinge arm, a separate mounting plate, and
one or more separate intermediate adjusting parts. Further, many of
such devices are complicated and inconvenient to install and use,
and in some of such devices, removal of the door may be required in
order to make an adjustment.
SUMMARY OF THE INVENTION
The present invention overcomes the problems associated with the
prior art devices and provides an adjustable recessed hinge for
mounting a door member on a supporting frame member which is simple
and inexpensive to make and easy to install and use.
To achieve these objects in accordance with the invention, an
adjustable recessed hinge for mounting a door member on a
supporting frame member is provided that includes a hinge cup which
is displaceably insertable in a bore of either a frame member or a
door member, a hinge pin mounted in the hinge cup, and a hinge arm
having one end pivoted on the hinge pin and having an opposing end
on which is formed a hinge plate that is displaceably securable to
the other of the frame or door members.
Preferably, the hinge plate of the hinge arm is displaceable
relative to the member to which it is secured in a direction which
is parallel to the pivot axis of the hinge pin, and the hinge cup
is configured and dimensioned to be displaceable within the bore
relative to the member to which it is secured in a direction which
is perpendicular to the pivot axis of the hinge arm.
Additionally, a slotted hole having a longitudinal axis extending
parallel to the pivot axis of the hinge pin is provided in the
hinge plate to receive a fastening screw for securing the hinge
plate to the particular member and, in cooperation with the
fastening screw, to guide the displacement of the hinge plate in
such direction. Thus, in an arrangement of an upright door mounted
on an upright, stationary supporting frame member, the door member
can be adjusted or repositioned vertically relative to the
supporting frame member on loosening of the fastening screw in the
slotted hole of the hinge plate of the hinge arm.
Further, the hinge cup has a securing flange extending outwardly
from each of opposing side portions of the top edge of the hinge
cup, each of which securing flanges is provided with a slotted hole
having a longitudinal axis which is perpendicular to the pivot axis
of the hinge pin to receive a fastening screw for securing the
hinge cup to the particular member and, in cooperation with the
fastening screws, to guide the displacement of the hinge cup. In a
similar arrangement of an upright door mounted on an upright,
stationary supporting frame member, the door member can be adjusted
or repositioned horizontally relative to the supporting frame
member on loosening of the fastening screws in the slotted holes of
the securing flanges.
These and other objects and advantages of the present invention
will become more apparent after consideration of the following
detailed specification taken in conjunction with the accompanying
drawings wherein like characters of reference designate like parts
through the several views.

DETAILED DESCRIPTION OF THE DRAWINGS
Reference will now be made in detail to one or more preferred
embodiments of the invention which are illustrated in the
accompanying drawings.
Referring to FIGS. 1 to 3, the adjustable recessed hinge comprises
a hinge cup 2 to which hinge arm 4 is connected. Hinge arm 4 is
pivoted on hinge pin 6 which is engaged at both ends in seatings 8
within sidewalls 10. Sidewalls 10 define between them a recess 12
within which hinge arm 4 engages and is pivotable on hinge pin
6.
Hinge cup 2 is inserted into a bore defined by a substantially
circular interior wall 14 and bottom 16 on the inside of a door
member 18. Hinge cup 2 has front and rear exterior walls 20, 22
spaced diametrically from each other a distance which is less than
the diameter of the interior of the bore, leaving spaces 24, 26
between interior wall 14 of the bore and exterior walls 20, 22,
respectively, of hinge cup 2 to allow displacement or shifting of
the position of hinge cup 2 within the bore relative to door member
18.
Referring to FIG. 3, a circumferential flange 64 is provided at the
top edge of hinge cup 2 which engages the top edge of the bore and
provides a limit for the depth of insertion of hinge cup 2 into the
bore. Hinge cup 2 also has a pair of securing flanges 28, 30 which
extend outwardly from opposing sides of the top edge of hinge cup
2, each of which is provided with a slotted hole 32, 34., and each
of which has a longitudinal axis that extends perpendicular to the
pivot axis of hinge pin 6. Hinge cup 2 is secured within the bore
by the insertion through slotted holes 32, 34, respectively, of
fastening screws 36, 38 which can be driven into door 18.
Referring to FIGS. 1, 2, and 4, hinge arm 4 is pivoted at end 40 on
hinge pin 6, and hinge plate 42 is formed integrally on the
opposing end of hinge arm 4. Hinge plate 42 is provided with at
least one slotted hole 44 having a longitudinal axis which extends
parallel to the pivot axis of hinge pin 6. Hinge plate 42 is
secured to supporting frame member 46 by the insertion of a
fastening screw 48 through slotted hole 44 which can be driven into
supporting frame member 46. Preferably, hinge plate 42 is provided
with ledge 50 which engages a corner of supporting frame member 46
to further secure hinge plate 42. However, ledge 50 can be omitted
entirely from hinge plate 42.
Displacement or repositioning of the door member 18 relative to
supporting frame member 46 in a direction perpendicular to the
pivot axis of hinge pin 6 can be accomplished by loosening of
fastening screws 36, 38 and shifting hinge cup 2 within the bore in
the direction of the longitudinal axes of slotted holes 32, 34
within the limits afforded by spaces 24, 26 between interior wall
14 of the bore and exterior walls 20, 22, respectively, of hinge
cup 2.
Displacement or repositioning of the door member 18 relative to
supporting frame member 46 in a direction parallel to the pivot
axis of hinge pin 6 can be accomplished by loosening of fastening
screw 48 and shifting hinge plate 42 of hinge arm 4 in the
direction of the longitudinal axis of slotted hole 44.
In an alternate embodiment, FIGS. 5, 6, slotted holes 52, 54 are
provided in securing flanges 28, 30 of hinge cup 2, each of which
has a longitudinal axis extending parallel to the pivot axis of
hinge pin 6, and hinge plate 42 of hinge arm 4 is provided with
slotted hole 56 having a longitudinal axis which extends
perpendicular to the pivot axis of hinge pin 6. In such alternate
embodiment, displacement or repositioning of door member 18
relative to supporting frame member 46 in a direction parallel to
the pivot axis of hinge pin 6 is accomplished by a loosening of
fastening screws 58, 60, and displacement or repositioning of door
member 18 relative to supporting frame member 46 in a direction
perpendicular to the pivot axis of hinge pin 6 is accomplished by a
loosening of fastening screw 62, in which case ledge 50 (FIGS. 1,
2, and 4) is omitted from hinge plate 42 to accommodate
repositioning of hinge plate 42 on supporting frame member 46.
Further, the respective mountings of hinge cup 2 on a door member
and hinge plate 42 of hinge arm 4 on a supporting frame member may,
if desired, be reversed from the standpoint of the door member and
supporting frame member, that is, between two parts that can be
opened and closed with respect to each other.
