Abstract
Abstract This disclosure relates to a novel hinge, particularly a hinge for concealed arrangement between abutting door sashes, particularly a furniture hinge for furniture doors and the like, the hinge comprising a pair of hinge elements, a pair of connecting rods having first and second opposite ends, first pivot means connecting first ends of the rods to a first of the hinge elements, an arm having first and second ends, second pivot means connecting second ends of the rods to the first arm end, third pivot means connecting the second arm end to the second hinge element, means mounting the second hinge element and arm for relative sliding movement in a direction generally normal to the axis of the third pivot means, and means for selectively adjusting the angular relationship between the arm and the second hinge element. The hinge is locked both as to its angular relationship and its sliding relationship by a single screw which is disposed between the third pivot means and the adjusting means, with the latter also being a screw. In keeping with an embodiment of the invention the arm and the second hinge element are formed as opposed U-shaped members which open in a direction toward each other, and in another embodiment of the invention one of the pair of rods is formed of two portions with one being pivotally mounted immediately its end to the other of the rods.
