<p>Abstract A hinge that incorporates two pivotally interconnected hinge flanges with symmetrically located screw holes that allow for the hinge to be reversible. The opposing hinge flanges are off-set from the central pivoting knuckle such that the closed hinge dimension maintains an accurate door gap and allows for simple surface mounting of the hinge, and eliminates the need to of a skilled person to recess the hinges. The rear face of the hinge flanges contain symmetrically protruding deformation screw holes that provide positive locating, with the protruding deformations distributing the load through the hinge and removing the shear load off the individual screws. In addition, this hinge can be converted into a lift-off hinge simply by using a second door flange for use as a frame flange to secure to the frame. A removable pin within the central pivoting knuckle is used enabling separation of the flanges to easily remove a door without having to remove the hinge. 240 X ' 270 -270 0 Q '260 -- 220 270 0260 26 Fig. 6 230 Fig. 7 +0220 Fig. 5</p> |
