According to the invention, a positioning element is displaceably or pivotably supported on the installation support, and the positioning element is disposed in a displacement range of the bearing part along the displacement path. The invention further relates to a lifting device having such a flap bearing and a method for adjusting such a flap bearing. The flap bearing can be simply and quickly adjusted to the correct position thereof so that the flap, folding flap, door, or the like closes completely. ## Claims ### Claim 1 A flap bearing for coupling a control arm of a prestressed lifting device in an articulated manner to a flap of an item of furniture, the flap bearing comprising: an installation support configured to be fastened to the flap; a bearing part including a pivot bearing configured to be coupled to the control arm, the bearing part being displaceably supported on the installation support such that the bearing part is displaceable in a displacement range relative to the installation support along a displacement path: and a positioning element displaceably supported on the installation support such that the positioning element is disposed in the displacement range of the bearing part along the displacement path; wherein the installation support includes a stop configured to limit the displacement path of the bearing part in a direction of a lifting force transmitted from the control arm to the flap bearing; and wherein the bearing part includes an adjustment screw configured to adjust the displacement range of the bearing part in the direction of the lifting force. ### Claim 2 (depends on 1) The flap bearing of claim 1, wherein: displacement directions of the positioning element and the bearing part are identically oriented. ### Claim 3 (depends on 1) The flap bearing of claim 1, wherein: the installation support includes a guide; and the bearing part and the positioning element are supported on the guide. ### Claim 4 (depends on 3) The flap bearing of claim 3, wherein: the guide is configured to guide the bearing part and the positioning element on a linear path. ### Claim 5 (depends on 1) The flap bearing of claim 1, wherein: the positioning element is supported on the installation support such that the positioning element is held in position relative to the installation support without external force above a specified threshold value being applied. ### Claim 6 (depends on 1) The flap bearing of claim 1, wherein: the positioning element is disposed along the displacement path in a direction from bearing part opposite of the lifting force. ### Claim 7 (depends on 1) The flap bearing of claim 1, wherein: a displacement range of the positioning element is limited in a direction from the bearing part opposite of the lifting force by a latching connection between the positioning element and the installation support. ### Claim 8 (depends on 1) A lifting device including the flap bearing of claim 1 in combination with the control arm. ### Claim 9 (depends on 8) The lifting device of claim 8, wherein: the control arm is adjustable in length. ### Claim 10 A method of adjusting a flap bearing relative to a flap of an item of furniture, the flap bearing including: an installation support fastened to the flap, a bearing part including a pivot bearing, the bearing part being supported on the installation support for displacement along a displacement path, and a positioning element displaceably supported on the installation support; the item of furniture including a flap holder fastened to a furniture frame, and a control arm pivotally connected to the pivot bearing and the flap holder; the method comprising: (a) displaceably supporting the positioning element on the installation support, such that the positioning element is disposed in a displacement range of the bearing part along the displacement path of the bearing part; (b) closing the flap such that the bearing part strikes the positioning element and displaces the positioning element into a setting position; (c) opening the flap while the positioning element remains in the setting position; and (d) adjusting and limiting the displacement path of the bearing part relative to the installation support in a direction of a retaining force transmitted from the flap holder to the bearing part such that the bearing part bears against the positioning element.
