The device includes a positioning mechanism with a positioning portion formed in an intermediate region between the at least one pivot arm and the base unit. During a pivoting movement of the pivot arm, the positioning portion contacts an abutment surface on the pivot arm and/or on the base unit. Fine positioning of the pivot arm in an axial direction relative to its pivot axis is configurable by contact of the positioning portion with the abutment surface if the pivot arm has an axial offset with respect to a setpoint bearing position of the pivot arm. ## Claims ### Claim 1 A device for moving a furniture part held on a furniture body of an item of furniture, comprising a guide with at least one pivot arm for pivoting the furniture part, the guide allowing the furniture part to be moved from a closed position into an open position of the furniture part relative to the furniture body and back, the device having a base unit with an anchor plate on which the guide engages such that a pivot axis about which the at least one pivot arm is pivotable is transverse with respect to an anchor plate plane spanned by the anchor plate, wherein the device comprises a positioning mechanism with a positioning portion, the positioning portion being formed in an intermediate region between the at least one pivot arm and the base unit, the positioning portion being provided such that, during a pivoting movement of the at least one pivot arm, the positioning portion comes into contact with an abutment surface, the abutment surface being provided on the pivot arm and/or on the base unit, fine positioning of the pivot arm in an axial direction relative to the pivot axis of the pivot arm being configurable by contact of the positioning portion with the abutment surface if the pivot arm has an axial offset with respect to a setpoint bearing position of the pivot arm. ### Claim 2 (depends on 1) The device as claimed in claim 1, wherein the abutment surface is formed by an outer side of the at least one pivot arm. ### Claim 3 (depends on 1) The device as claimed in claim 1, wherein the abutment surface is formed by an inner side of the base unit. ### Claim 4 (depends on 1) The device as claimed in claim 1, wherein the abutment surface is provided on the anchor plate of the base unit. ### Claim 5 (depends on 1) The device as claimed in claim 1, wherein the abutment surface on the base unit is formed exclusively in a region of the base unit which is not swept over by predefined portions of the outer side of the at least one pivot arm during the course of a complete pivoting movement of the pivot arm arrangement. ### Claim 6 (depends on 1) The device as claimed in claim 1, wherein the abutment surface is provided on a counterpart plate, situated opposite the anchor plate, of the base unit. ### Claim 7 (depends on 1) The device as claimed in claim 1, wherein the abutment surface is assigned to a face-side cover element that is attachable to the base unit. ### Claim 8 (depends on 1) The device as claimed in claim 1, wherein the abutment surface is formed as a positioning portion correspondingly to the positioning portion on the pivot arm. ### Claim 9 (depends on 1) The device as claimed in claim 1, wherein the positioning portion comprises an attachment element for attachment to the base unit and/or to the pivot arm. ### Claim 10 (depends on 1) The device as claimed in claim 1, wherein the attachment element is attachable to the base unit and/or to the pivot arm. ### Claim 11 (depends on 1) The device as claimed in claim 1, wherein the positioning portion is formed from a plastics material. ### Claim 12 (depends on 1) The device as claimed in claim 1, wherein the base unit is connected via a pivot arm of the guide to a mounting unit, the mounting unit being designed for recessed attachment in the region of a material recess of the furniture part. ### Claim 13 (depends on 1) An item of furniture having a furniture body and, held thereon, a movable furniture part with a device as claimed in claim 1.
