Mechanisms used to move the body of a piece of jewelry or an item of costume jewelry

By using a manual power source to drive the transmission device and support system, the gemstone is pivoted around two or three rotation axes, solving the problems of poor visibility and scintillation effect of the gemstone during rotation and achieving an all-round display of the gemstone.

AI Technical Summary

Technical Problem

In the prior art, the rotation of the gemstone is single-axis, which limits its visibility and scintillation effect, and makes it difficult for the observer to directly observe the full picture of the gemstone.

Method used

A manual power source is used to drive the transmission device, which pivots the object around two or three rotation axes through a support system. Combined with eccentric drive elements and compound motion, the visibility and flashing effect of the object are increased.

Benefits of technology

By giving the object a compound motion with two or three rotational degrees of freedom, the visibility and scintillation effect of the gemstone are significantly improved, allowing the observer to directly observe the full appearance of the gemstone from multiple angles.

Abstract

A mechanism (1) for moving an object (11), the mechanism being suitable for being integrated into an item of wearable jewellery or costume jewellery (3), the mechanism comprising: a manual drive source (5) which can be driven directly or indirectly by an action of a user and is arranged to drive a transmission (9) following the action of the user; a support system (13) which carries the object (11) intended to be moved in rotation about a first axis of rotation (A1) by means of the transmission (9) under the action of the manual drive source (5), characterised in that the support system The system (13) comprises a first frame (13b) mounted to pivot on a frame element about a first rotation axis (A1) and an inner frame (13f) mounted to pivot in the first frame (13b) about a second pivot axis (A2), the second pivot axis being substantially orthogonal to the first pivot axis (A1); and wherein the object (11) is arranged to be driven by an eccentric drive element (15b) rigidly connected in rotation to a drive wheel (15), the drive wheel being arranged to be driven by a transmission (9).
