Claims
- 1. An articulated hinge for pivotally connecting a door flap to the carcass of a piece of furniture which has spaced carcass walls and a frame, said frame facing the door and extending essentially at right angles to the carcass walls and confining a free door opening, said door flap in closed position partially overlapping said frame, said hinge comprising: a carcass-related hinge part adapted to be connected to an edge surface of the frame offset inwardly relative to the adjacent carcass wall, and a door-related hinge part pivotally connected to the carcass-related part via a link mechanism and adapted to be connected to the door flap, said link mechanism being a cross-link mechanism with two cross-link arms pivotally interconnected in their central areas in the manner of a pair of scissors, one end of each cross-link arm being respectively directly connected to one of said carcass-related hinge part and said door-related hinge part, and another end being respectively pivotally indirectly coupled to the other hinge part via a link, said cross-link arms and said link indirectly coupling one of said cross-link arms with the carcass-related part, each having two sidewalls arranged in parallel spaced relationship to each other, and an over-center mechanism adapted to arrest the hinge in the closed position, said over-center mechanism having a two-arm cam lever journalled in the space between the sidewalls of the cross-link arms and the sidewalls of the link, said link being pivotally connected to said carcass-related part, said two-arm cam lever having a first lever arm facing the door related part, a spring pretensioning said first lever arm in a direction of an abutment at the carcass-related part, said two-arm cam lever also having a second lever arm with a top side facing away from the door-related part, said top side being a cam surface which cooperates with an actuating element provided between the sidewalls of said link in all positions with the exception of the hinge positions in the immediate vicinity of the closed position thereof, the arrangement being such that the first lever arm is held lifted off the carcass-related part against the pretension of said spring.
- 2. An articulated hinge according to claim 1, in which a bearing pin pivotally interconnecting said cross-link arms in the manner of a pair of scissors, will, when approaching the closed position of the hinge engage said first lever arm before said actuating element disengages from the cam surface of said second lever arm of said two-arm cam lever.
- 3. An articulated hinge according to claim 2, in which said bearing pin is in the space between the sidewalls of the cross-link arms, and in which said first lever arm has a cam surface, a roller rotatably supported on said bearing pin, said roller upon approaching the closed position of the hinge running against said cam surface of the first lever arm.
- 4. An articulated hinge according to claim 1, in which said actuating element cooperating with the cam surface of the second lever arm of the cam lever is a transverse pin held with its ends in bores in the sidewalls of a said link.
- 5. An articulated hinge according to claim 1, in which said carcass-related part is provided with a connecting flange protruding on both sides in the direction of the longitudinal extension of the frame edge face to which it is to be mounted, said connecting flange being provided on both sides of the carcass-related part with an oblong hole, each extending in the direction of said longitudinal extension, through said oblong hole the threaded shaft of one connecting screw each being passable.
- 6. An articulated hinge according to claim 5, in which said connecting flange is dimensioned to have approximately the width of the frame edge surface and is provided at its front and rearward marginal areas with relatively low extensions for resting against the front and rear sides of the frame, respectively.
