Description

The present invention relates to a fitting, designed as a furniture fitting or building fitting, for the movable mounting of a pivoting element, in particular a movable furniture part, relative to a stationary structure, in particular a furniture body, comprising: at least one base body to be attached to the stationary structure, at least one adjusting arm to be connected to the swivel element, at least one spring device for applying force to the at least one adjusting arm, wherein the spring device is mounted on the at least one base body via at least one bearing device, at least one transmission mechanism for transmitting a force from the at least one spring device to the at least one adjusting arm, wherein the transmission mechanism has at least one transmission lever pivotable about a pivot axis, at least one force adjustment device for adjusting the force of the spring device on the at least one adjusting arm. Furthermore, the invention relates to a piece of furniture with a stationary structure, in particular a furniture body, and with at least one pivoting element mounted to be movable relative to the stationary structure, in particular a movable furniture part, and with at least one fitting of the type to be described for moving the pivoting element relative to the stationary structure. In the WO 2006/005086 A1 A furniture drive for moving a furniture flap is disclosed, wherein a pivotally mounted actuating arm is pre-tensioned by a spring device to compensate for the weight force of the furniture flap. The spring device is pivotally connected to an intermediate lever via an adjustable point of application, the intermediate lever pivoting the actuating arm via a pressure roller-control cam arrangement. By adjusting the point of application on the intermediate lever, the pre-tension of the spring device can be changed to to compensate for different weights of a swivel element connected to the positioning arm. The spring's block length (i.e., its length in a fully compressed state) limits the spring mechanism's force. For heavier furniture flaps, spring mechanisms with a higher spring force are required. However, this higher spring force also means that, in the closed position, the movable furniture part is pressed against the furniture body with a greater closing force relative to the furniture body. Each time the flap is opened, the user must overcome this closing force by manually pulling on the movable furniture part, requiring increased effort and often perceived as inconvenient. The object of the present invention is to provide a fitting of the type mentioned at the outset, avoiding the disadvantages discussed above. This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are defined in the dependent claims. According to the invention, at least one adjusting device (10), preferably separate from the at least one force adjusting device (8), is provided by which the position of the at least one joint axis (11) of the at least one transmission lever (9a) relative to the base body (5) can be adjusted. In other words, in addition to the force-adjusting device, the fitting also has an adjustment device by which the pivot axis of the at least one transmission lever can be adjusted relative to the base body. In this way, the kinematics of the transmission mechanism can be modified so that a stronger, and in particular a longer, spring device can be used as standard without significantly altering the closing force of the actuating arm in the closed position. Thus, in the design according to the invention, a higher A range of different weights of the swivel element are covered. According to a first embodiment of the invention, it can be provided that the at least one force adjustment device and the at least one adjustment device have a common adjustment element or at least two adjustment elements, preferably coupled to each other via at least one toothing, wherein the force of the spring device on the at least one adjusting arm and the position of the at least one pivot axis of the at least one transmission lever relative to the base body can be adjusted simultaneously by means of the common adjustment element or by means of the adjustment elements coupled to each other. According to a second embodiment of the invention, it can be provided that the at least one force adjustment device and the at least one adjustment device have two independent adjustment elements by which the force of the spring device on the at least one adjusting arm and the position of the at least one pivot axis of the at least one transmission lever relative to the base body can be adjusted independently of each other. The furniture according to the invention has a stationary structure, in particular a furniture body, at least one pivoting element mounted to be movable relative to the stationary structure, in particular a movable furniture part, and at least one fitt
