1. A furniture connecting fitting, comprising:
a base;
a mechanical linkage connected directly or indirectly to the base, the mechanical linkage being configured to move a door or a hatch between a closed position and an open position, the mechanical linkage including a plurality of levers and pivotal connections, at least one of the pivotal connections being fixed in position relative to the base as the mechanical linkage is adjusted between the closed position and the open position, wherein one of the levers is an attachment lever configured to be connected directly or indirectly to the door or hatch;
a biasing device including at least one spring element configured to provide a biasing force to the mechanical linkage;
an actuator lever connected to the mechanical linkage;
a swivel lever connecting the biasing device to the actuator lever;
an actuating lever pivotally connected at one pivotal connection to the actuator lever and at another pivotal connection to the mechanical linkage, wherein the actuating lever, the actuator lever and the swivel lever are pivotally connected together about a common pivot axis; and
an adjustment device including an adjustment element configured such that a force transfer point of the biasing device relative to the actuator lever is adjustable by the adjustment element;
wherein the furniture connecting fitting includes a front end and an opposite rear end, the front end configured to face in a forward direction toward the door or hatch;
wherein the biasing device is configured to provide the biasing force to the mechanical linkage from the at least one spring element primarily in the forward direction such that when the at least one spring element is released or partially released the mechanical linkage is displaced in the forward direction;
wherein the biasing device includes a connection element pivotally connected to the swivel lever by a bearing such that a force transfer point from the biasing device to the swivel lever is formed by the bearing; and
wherein a position of the bearing relative to the actuator lever is adjustable by the adjustment element.
