An orbital platform mechanism for laboratory shakers and incubators consists of a base (1), a platform (20), compliant mounting means (7, 8, 10, 11) supporting the platform from the base and a drive motor coupled to the platform by means of an eccentric (3) for causing orbital motion of the platform relative to the base. The compliant mounting means consists of an intermediate support member (6) mounted from the base (1) by means of a first pair of parallel spring metal strips (7, 8), and a platform support member (12) mounted from the intermediate support member (6) by means of a second pair of parallel spring metal strips (10, 11), and the first and second pairs of strips are orthogonally disposed. The resultant mechanism provides a simple and cost-efficient orbital mechanism which can readily be powered by a small electric motor. |
