Abstract

Connection closure for jewelery, in particular chains and bracelets, made of metal in the form of an S-hook with securing mechanism, characterized in that the receiving slot (3) of a hook loop (1) is severely narrowed and the receiving slot (4) of the other hook loop (2) Help a movable hollow cylinder (7) on the center piece (8) of the S-hook, which is held by the ball (6) at the end of the hook loop (1), closed and can be opened.

Description

For jewelry, such as necklaces and bracelets, there are a variety of closures. Various closures include springs and / or screws. These components of the closure can not be heated or cleaned in acid. Thus, they must be separated in advance from the rest of the piece of jewelry. This step is cumbersome and can be avoided by choosing a closure that does not include any of these components.

One possible lock that bypasses these components is an S-hook. The disadvantage of a simple S-hook is that when worn, the ends of the piece of jewelry can come loose from the hook loops. The invention presented here is intended to circumvent this problem. The shutter consists of a wire which is shaped like a S. At the ends of the wire are balls which are larger than the diameter of the wire used. On the almost straight center piece, which connects the two hook loops of the S-hook, there is a movable hollow cylinder. The hook loops are shaped so that there is a receiving slot between the ball at the end of the hook loop and the center piece of the S-hook. To counteract the problem that the end of the piece of jewelry slides out of the hook loops, a hook loop is hooked into the end of a piece of jewelry, such as an eyelet, and the receiving slot of this hook loop is narrowed so much that the eyelet can not slip out of the hook loop. In order to narrow the receiving slot of the second hook loop, an additional securing mechanism is necessary. In the case of this invention, the constriction of this receiving slot is made possible by the movable hollow cylinder on the center piece of the S-hook. This hollow cylinder can be held by means of the balls at the ends of the hook loops. Depending on the position of the hollow cylinder on the center piece of the S-hook, the receiving slot of the second hook loop is opened or closed. To allow the movement of the hollow cylinder past the balls, the ends of the hollow cylinder are chamfered. Nevertheless, it requires a certain amount of force, which prevents accidental opening of the receiving slot. The round balls are another distinguishing feature of many other S-hooks in this invention. It has the advantage that there are no sharp ends that can damage clothing or skin.

The present invention consists of only two parts that interact so easily that handling is very easy. The closure can be operated with one hand and without eye contact.

The closure can be made of precious metal, but also of brass, copper and similar materials. In addition, he can be gold plated in the gold bath.

The material can be chosen so that the S-hook is made of wire of the same material as the rest of the piece of jewelry. The balls are made of the molten metal and soldered to the ends of the wire. Before, a hollow cylinder made of the selected material is pulled onto the wire. The inner diameter of the hollow cylinder is chosen to be slightly larger than the diameter of the wire.

Depending on the aesthetic sensibility and the customer's request, not only the material but also the size, symmetry, ovality of the hook loops and much more can be varied. Due to the appealing design, the closure can also be worn as a decorative part of the piece of jewelry.
