A hinge (10) for furniture doors, the supporting wall stop part of which, which is constructed as a supporting arm (14), is coupled pivotably over two hinge guide rods (16; 18) with the door stop part, which is constructed as a hinge pot (12), with a spring-loaded mechanism, which it is formed by a leg spring, which is disposed in the supporting arm and engages an extension of the out to hinge guide rod (16), and a further leg spring, which is supported in the supporting arm. The leg spring is constructed as a double leg spring (42) with a middle double leg (44) of two parallel leg arms, protruding between two groups of spring coils (47) from, in each case, one of the inner spring coils, and two outer legs (46), protruding from the in each case outermost spring coil of each group. The middle double leg is constructed arc-shaped at its free end and embraces the hinge pin (22), which carries the inner hinge guide rod pivotably, at least partially with this arc-shaped end through a central recess in the bearing lug (38) of the inner hinge guide rod (18) on the side of the supporting arm and is held rotatably on the hinge pin (22). The free ends of the legs (46), protruding from the outer spring coils, are held in a recess (50) of the extension of the outer hinge guide rod so that they can be rotated about an axis extending parallel to the axis of the hinge pin (20) of the outer hinge guide rod (16) on the side of the supporting arm, the double leg spring (42) being held exclusively by the double leg (44) and the outer leg (46) in the supporting arm (14).

1. A spring-loaded hinge for furniture doors comprising inner and outer hinge links each having a first and second end, each pivotably hinged to a first and second hinge pin on a door-related mounting part at the first end and to an extended supporting arm at the second end, wherein the extended supporting arm, when swiveling from a closed position to an open position, is movable over a dead center position, wherein in the dead center position, the extended supporting arm is biased toward both the closed and open position by a torsion coil spring, the torsion coil spring, disposed in a door-side end region of the extended supporting arm, being formed as a double leg spring comprising an inner double leg of two parallel leg arms, which protrude between two groups of outer spring coils from a single inner spring coil, the leg arms being integrally connected with one another by a cross member, the double leg spring further comprising two outer legs, each protruding from a respective outermost spring coil of each group, the two outer legs engaging a supporting arm-side extension of the outer hinge link remote from the door-related mounting part, the supporting arm-side extension forming a lever arm with respect to a supporting arm-side swiveling axis of the outer hinge link, the inner double leg being supported at the first hinge pin supporting the inner hinge link in the supporting arm, wherein the ends of the two outer legs, protruding from the respective outermost spring coil of each group, being rotatable about an axis extending parallel to the axis of the second hinge pin supporting the outer hinge link in the supporting arm, are disposed in a recess of the supporting arm-side extension of the outer hinge link, wherein the inner double leg, at its free end connected by the cross member, is constructed arc-shaped and, through a central recess in a supporting arm-side pivot eye of the inner hinge link, embraces the first hinge pin of the supporting arm, which first hinge pin pivotably supports the inner hinge link, at least partially, and the first hinge pin holds the inner hinge link so that the inner hinge link can rotate on the first hinge pin, and the double leg spring being held exclusively by the inner double leg and the two outer legs in the supporting arm. 2. The spring-loaded hinge of claim 1, wherein the outer hinge link comprises, on the supporting arm side thereof, bent-over side walls at its opposite longitudinal edges, the side walls having boreholes for pivotably supporting the second hinge pin of the supporting arm, wherein the extension is formed ,a as an elongation of each of the side walls, the elongation for each of the side walls comprising an open recess in which a bent-over end section of each respective leg of the two outer legs engages so that it can be rotated relative to the respective elongation, the bent-over sections of the two outer legs extending parallel to the axis of the second hinge pin.
