The invention relates to a stay 9 for holding a flap or a lid in a closed position or open position in relation to a container to be closed thereby. It has a first arm 9 and a second arm 10. These are intended to be fixed to the container and lid respectively by means of a pivot bearing. The two arms are connected to one another via a further pivot bearing. Active between the two is a compression spring 16 which supports the arms 9, 10 relative to one another in a position near to or remote from one another. For this purpose, the compression spring 16 is supported at one end 17 on the first arm 9 and at its other end 18 on the second arm 10, in such a way that, on the second arm, it is arranged eccentrically to the pivot bearing 13. In the extended position of the arms 9, 10, the engagement point of the compression spring 16 on the second arm 10 is offset to one side of a connecting line 27 between the centre point of the first pivot bearing 6 on the first arm 9 through the third pivot bearing 13 between the two arms 9, 10 and, in the position which corresponds to the closed position of the two arms and in which these are near to one another, the said engagement point is offset to the other side of the connecting line 27. This ensures a stay which is of simple design and which assumes a reliable holding-shut position, so that the holding-shut and holding-open forces can be predetermined exactly. The necessary forces for the closed position or open position can be achieved and predetermined in a simple way by exchanging the spring or by varying the support of the second arm relative to the first arm via the spring. <IMAGE> |
