Abstract

A translating hinge includes a translation element which provides translational movement between two objects coupled by the translating hinge and a rotating assembly coupled to the translation element.

Claims

1. A translating hinge assembly coupling a first object and a second object, the translating hinge comprises:

a translation assembly movable between a closed position and a translated position;

a rotating assembly coupled to the translation assembly enabling the first object to be rotated relative to the second object about an axis perpendicular to the direction of translation, wherein the translation assembly comprises;

a hinge pin having first and second opposing surfaces with a first or top surface of the hinge pin having a bore provided therethrough;

a screw having a first end coupled to the hinge pin and having a second end, the second end of the screw affixed to the second object, the screw being disposed within and projecting through the bore of the hinge pin;

a pair of yoke blocks movably coupled to and projecting from opposing ends of the hinge pin;

a first washer disposed over a shank of the screw and disposed against a second or bottom surface of the hinge pin;

a compression coil spring disposed over the shank of the screw with a first end of the spring disposed against a surface of the first washer,

a second washer disposed over the second end of the compression coil spring wherein the first and second washers keep the compression coil spring centered on the screw,

wherein the rotating assembly rotatably couples the hinge pin to the first object,

wherein the translation assembly moves between the closed position and the translated position solely by substantially true vertical translation of the first object relative to the second object;

wherein the rotating assembly allows the first object to be rotated relative to the second object in response to the translation assembly being in the translated position;

wherein the compression coil spring biases the hinge pin and the second object apart in the direction of the true vertical translation.

2. The hinge assembly of claim 1 wherein the bore accepts a head of the screw while the shank of the screw passes through the hinge pin such that the bore in the hinge pin keeps the hinge assembly low profile by allowing the head of the screw to reside in the hinge pin bore after translation is complete.

3. The hinge assembly of claim 1 wherein the compression coil spring is selected having a spring stiffness which ensures translation only occurs when desired.

4. The hinge assembly of claim 1 wherein the screw is provided as a shoulder screw having a predetermined diameter.

5. The hinge assembly of claim 1 wherein the yolks are provided having alignment slots provided therein.
