Low profile adjustable soft close hinge apparatus
Disclosed is a low profile, adjustable, soft close hinge comprised of a hinge cup pivotally connected to a hinge body via a hinge arm and a hinge link in a four-bar linkage arrangement. A spring biases the hinge to a closed position. The hinge body is adjustably connected to an inner frame with an overlay adjustment screw and depth adjustment cam. The inner frame releasably connects the hinge body to a mounting plate. A stop bracket is adjustably and slidably connected to the hinge body by a cam. The adjustable position of the stop bracket relative to the hinge body determines the point at which the damping functionality of a damper begins during a hinge closing movement. A linkage sub-assembly pivotally connects the damper to the hinge link.

6. The adjustable soft close hinge of claim 5 wherein the hinge link is comprised of a plurality of interlocking plates.
7. The adjustable soft close hinge of claim 1 further comprising:
a linkage sub-assembly comprising a pivot link and a connecting link;
the pivot link connecting the damper and the connecting link; and,
the connecting link connecting the pivot link and the hinge link.
8. The adjustable soft close hinge of claim 1 further comprising:
a first spacer adjacent the hinge link and the hinge body and a second spacer adjacent the hinge link and the hinge body.
9. The adjustable soft close hinge of claim 1 wherein the soft close cam further comprises:
a base section adjacent the hinge body;
a neck section seated within the hinge body and adjacent to and concentrically aligned with the base section along a first axis;
the offset protrusion extending from the neck section along a second axis and engaging a hole in the stop bracket; and,
wherein upon rotation of the soft close cam, the offset protrusion urges the stop bracket to move longitudinally relative to the hinge body.
10. The adjustable soft close hinge of claim 1 wherein a longitudinal position of the closed end is altered by rotation of the soft close cam.
11. The adjustable soft close hinge of claim 1 further comprising:
a set of graduated indicia on the hinge body surrounding the soft close cam; and,
a radial indicator on the soft close cam, adjacent the set of graduated indicia.
12. The adjustable soft close hinge of claim 1 wherein the hinge cup, the hinge body, the hinge arm, and the hinge link form a four-bar linkage arrangement biased by a spring.
13. A low profile, soft close hinge comprising:
a hinge body pivotally connected to a hinge cup by a hinge arm and biased by a spring;
the hinge body pivotally connected to the hinge cup by a hinge link;
an inner frame adjustably connected to the hinge body;
a stop bracket, having a slot with an open end and a closed end, and adjustably connected to the hinge body by a soft close cam, where a pin is slidably engaged with the slot;
an offset protrusion extending from the soft close cam and engaging the stop bracket;
a damper, having a damping function, slidable within the stop bracket;
the damper pivotally connected to the hinge body by the pin;
the damper pivotally connected to the hinge link and slidably connected to the hinge body;
wherein upon rotation of the soft close cam, the offset protrusion rotates within the stop bracket and adjusts a longitudinal position of the stop bracket relative to the hinge body such that onset of the damping function is adjusted; and,
wherein the onset of the damping function begins when the pin abuts the closed end.
14. The low profile, soft close hinge of claim 13
wherein as the hinge moves from an open position to a closed position, the pin abuts the stop bracket.
15. The low profile, soft close hinge of claim 13 wherein the hinge link is comprised of a plurality of interlocking plates.
16. The low profile, soft close hinge of claim 13 further comprising:
a peak on the hinge link;
a spring arm, extending from the spring, adjacent the hinge body;
a spring brace, extending from the spring, contacting the peak; and,
wherein during a closing movement of the hinge, the spring brace maintains contact with the peak.
17. The low profile, soft close hinge of claim 13 further comprising:
an overlay adjustment screw engaged with the hinge body and slidably attached to the inner frame; and,
wherein upon rotation of the overlay adjustment screw, a relative distance between the hinge body and the inner frame is altered.
18. The low profile, soft close hinge of claim 13 further comprising:
a depth adjustment cam seated in the hinge body and rotatably connected to the inner frame; and,
wherein upon rotation of the depth adjustment cam, a longitudinal position of the hinge body relative to the inner frame is altered.
