ABSTRACT:
A simple to use, durable and effective securing means for an interchangeable wearable jewelry item having a base unit and a feature unit is described. The securing means includes a receiving structure being provided with a resilient insert and being contained within the base unit, the resilient insert being provided with a threaded, and essentially tapered hole having a wider opening at one end and a narrower opposite end; and a threaded stem having one end for setting the feature unit, and the opposite end for frictionally engaging the receiving structure by way of the tapered hole. The threaded stem structure could be securely engaged to the receiving structure by urging the threaded stem through the wider opening of the tapered hole, and adjusting the threaded stem further into the narrower end of the tapered hole thereby more frictionally engaging the receiving structure, or the threaded stem could also be disengaged from the receiving structure by adjusting the threaded stem in the reverse direction, whereby the feature unit could be mounted securely on the base unit, or disengaged from the base unit and selectively mounted securely on a different base unit having also such a receiving structure. By having a set of different feature units and another set of base units, each unit of both sets being provided with the securing means, many desirable combinations of the jewelry having entirely different appearances can be obtained for wearing as the user's taste changes, or for wearing on different occasions.
