Zusammenfassung: | A self-orienting revolving fixture for furniture which is of the type having parallel plates relatively rotatable about a central axis with antifriction means between the plates, a coil spring that has at least one convolution surrounding said axis with means on the plates to stress the spring by pulling circumferentially in opposite directions on the ends of the spring, there being a guide finger positioned radially inwardly from the spring and substantially in contact with the spring convolution in oriented position, the guide finger restricting bodily shifting movement and preventing differential stressing of the spring during relative rotation of the plates. |
