Abstract

A furniture hinge includes a first hinge portion to be fixed to a furniture carcass, a second hinge portion having a hinge cup to be fixed to a movably-mounted furniture part, a hinge axis connecting the first hinge portion and the second hinge portion, a bearing portion inserted into the hinge cup, the bearing portion including a cavity, and a spring device configured to move the furniture hinge from a predetermined angular position into a fully closed position and/or into a fully open position. A first end region of the spring device is supported on the bearing portion when the bearing portion is inserted into the hinge cup, the cavity being configured to accommodate the spring device. A convex control curve configured to interact from the predetermined angular position towards the fully closed position with the spring device. A pressure portion has a counter contour configured to be pressed against the convex control curve by the spring device. The counter contour has a concave section complementary to the convex control curve.

Claims

1. A furniture hinge comprising:

a first hinge portion to be fixed to a furniture carcass;

a second hinge portion having a hinge cup to be fixed to a movably-mounted furniture part;

a hinge axis connecting the first hinge portion and the second hinge portion;

a bearing portion inserted into the hinge cup, the bearing portion including a cavity;

a spring device configured to move the furniture hinge from a predetermined angular position into a fully closed position and/or into a fully open position, wherein a first end region of the spring device is supported on the bearing portion when the bearing portion is inserted into the hinge cup, the cavity being configured to accommodate the spring device;

a convex control curve configured to interact from the predetermined angular position towards the fully closed position and/or fully open position via the spring device; and

a pressure portion having a counter contour configured to be pressed against the convex control curve by the spring device, wherein the counter contour has a concave section complementary to the convex control curve.

2. The furniture hinge according to claim 1, wherein the convex control curve and the counter contour, in an intermediate position of the furniture hinge which corresponds to the half-open position of the movably-mounted furniture part in the mounted condition, bear against each other.

3. The furniture hinge according to claim 1, wherein the convex control curve is motionally coupled to a movement of the furniture hinge and is pivotally mounted about the hinge axis of the furniture hinge.

4. The furniture hinge according to claim 1, wherein a plurality of hinge portions including the first hinge portion and the second hinge portion are connected to one another by at least five hinge axes.

5. The furniture hinge according to claim 1, wherein the spring device includes a helical spring.

6. The furniture hinge according to claim 5, wherein the helical spring is arranged within the hinge cup in a lying position and is arranged parallel to a base of the hinge cup.

7. The furniture hinge according to claim 5, wherein the hinge cup, together with the helical spring arranged therein, is arranged entirely within a cylindrical bore of the furniture part.

8. The furniture hinge according to claim 5, wherein the pressure portion is connected to a shaft, wherein the helical spring, at least partially, surrounds the shaft.

9. The furniture hinge according to claim 5, wherein the helical spring is a compression spring.

10. The furniture hinge according to claim 1, further comprising a damping device configured to dampen a movement of the furniture hinge, the damping device being mounted to or placed within a movably-mounted hinge portion connected via a hinge axis to the second hinge portion having a hinge cup so that the movably-mounted hinge portion is between the first and second hinge portions.

11. The furniture hinge according to claim 10, wherein the damping device, upon a movement of the convex control curve, is configured to move together with the convex control curve.

12. The furniture hinge according to claim 10, wherein the damping device includes a linear damper with a housing in which a piston with a piston rod are accommodated, wherein the piston rod, from the predetermined angular position towards the fully closed position and/or fully open position, is supported on a hinge portion and, one end of the housing is supported on a further hinge portion of the furniture hinge.

13. The furniture hinge according to claim 12, wherein the piston rod or the housing of the damping device, from the predetermined angular position towards the fully closed position and/or fully open position, is configured to interact with a protrusion arranged or formed on a hinge portion.

14. The furniture hinge according to claim 13, wherein the protrusion is an embossment.

15. The furniture hinge according to claim 10, wherein the furniture hinge has a switch movably arranged on a hinge portion and configured to be actuated by a person, the switch has a first switching position and a second switching position, wherein in the first switching position of the switch, a damping power of the damping device is deactivated or limited by causing a stop portion of the switch to interact with a counterstop portion of the damping device in order to restrict the movement of the damping device and wherein in the second switching position of the switch, the damping power of the damping device is activated by causing the stop portion of the switch to not restrict the movement of the damping device.

16. The furniture hinge according to claim 15, wherein the switch is arranged on the hinge portion on which the damping device is arranged, wherein the switch is movably mounted in a transverse direction with respect to a main longitudinal axis of the hinge portion.

17. The furniture hinge according to claim 16, wherein the transverse direction is at a right angle with respect to the main longitudinal axis of the hinge portion.

18. The furniture hinge according to claim 1, wherein the bearing portion, in the mounted condition, is entirely arranged within an internal cavity of the hinge cup.

19. A piece of furniture comprising:

a furniture body; and

a movable furniture part,

wherein said movable furniture part is movably mounted to said furniture body via said furniture hinge according to claim 1.
