A spring ring clasp, with a closed state in which the spring ring clasp (1) forms a closed ring (2), and with an opened state in which the ring (2) is opened, having an external tube (3), an internal tube (4) which in an overlap region (5) protrudes into the external tube (3), and a spring (6) which is disposed in a cavity (7) configured by the external tube (3) and the internal tube (4). For opening the spring ring clasp (1), the external tube being displaceable relative to the internal tube (4) counter to a spring force caused by the spring (6), and the spring (6) at least in the closed state protruding from the internal tube (4) and protruding into the external tube (3). The use of such a spring ring clasp (1) is in the jewelry industry but is not limited to this sector.

A key-ring included a first and a second ring slidably mounted relative to each other in a circumferential direction. The key-ring includes mutual engagement members configured to define a reference for an open ring configuration and/or a closed ring configuration.

A device comprising: a substrate; a first coating deposited on the substrate; an intermediate coating deposited on the first coating, wherein the first coating is interposed between the substrate and the intermediate coating; and a second coating deposited on the intermediate coating, wherein the intermediate coating is interposed between the first coating and the second coating, and the second coating is outermost and black. The substrate, the first coating, the intermediate coating and the second coating define at least one of a jewelry item and a component of a jewelry item.

The present invention relates to an integrally formed resilient holder which is configured in the form of a two-turn spiral ring body with an elongated configuration. The invented holder includes an upper loop and a lower loop having a size substantially different from that of the upper loop, such that pivot points are created at which the upper loop and the lower loop intersect each other. In the light of its deformability, the holder herein can be easily triggered to open up an entry port through which keys or rings may be introduced or removed by a simple press from the user. The invention is of high durability and versatility and is cost-effectiveness accordingly.

A key ring comprising a ring portion having a first end and second end, a rigid loop affixed to the first end, and a catch affixed to the second end for securely engaging and disengaging the rigid loop affixed to the first end is disclosed. The rigid loop and the catch can be typically disposed apart from each other with the ring portion in a relaxed state such that engaging the catch and the rigid loop holds tension between the first end and the second end to secure engagement of the catch and the rigid loop. The catch can be a hook having a tip extending into an enclosed area of the hook. The catch and the rigid loop can be oriented either in or transverse to the plane of the ring portion.

A securement device is provided. The securement device comprising: a ring comprising coplanar facing ends separated by a space; and a housing, a lock member positioned at least partially within the housing, wherein the lock member comprises a neck having a width less than the space, and a body having at least a portion with a width greater than the space; wherein the article is configured to adjust from a locked configuration to an unlocked configuration; the locked configuration preventing rotational translation of the ring through the housing; and the unlocked configuration allowing rotational translation of the ring through the housing.
