ABSTRACT:
Device for swivel holding of leaf flap which can swivel especially around a horizontal axis comprises a straight four-bar mechanism (8.1, 8.2, 10.1, 11.1) and elastic means (18) to damp the swivel motion. The elastic means have spring element (18) which is guided with its extensible part to move around anchoring element (7). Anchoring element (7) is for example a plastic ring which is inserted in hinged frame (1) of device. Its diameter corresponds to a multiple of a diameter of spring element (18). The entire device is preferably structured symmetrically with respect to the plane defined by the movement of four-bar mechanism (8.1, 9.1, 10.1, 11.1).
