Definitions
- This invention relates to a fastening device for jewellery.
- the invention relates to a fastening device that can be used to wear bracelets, chains and the like in a more secure and easier way.
- structurally unsophisticated fastening devices can be mentioned, such as simple hooks to be inserted in the end ring of a chain, or knots on opposite ends of a thread.
- More elaborate fastening devices are also known, equipped with locking elements operated by buttons.
- buttons or other similar elements are not always easily accessible, and in addition, their very small dimensions do not allow easy operation. It is also not uncommon for the buttons to be operated accidentally; the lack of solidity of the coupling, since the fastening elements are composed of small and very thin parts and consequently are not very resistant in case of impulsive forces; in some cases, they make the appearance of the bracelet not very homogeneous, as they interrupt the regularity of the succession of decorative elements fixed to the chain or to the support wire.
- a fastening device with sliding operation comprising two elements equipped with complementary profiles configured to engage and disengage each other, kept locked by a third element which allows them to be detached when operated.
- the object of the invention is therefore a fastening device for jewellery comprising a first element and a second element which can be fixed to respective ends of jewellery, wherein the first element has a top surface and a bottom surface, in which a socket is formed; the second element has a top surface, a bottom surface and a head, configured to interlock in a complementary way with the socket, so as to reversibly couple the first element with the second element; the second element comprises a groove, formed on its top surface, in which a sliding slider is housed, the first element comprises a recess, in a position adjacent to the socket, delimited by its top surface, so that, when the head is inserted in the socket, the slider remains in contact with the top surface of the first element at the recess, preventing the head from disengaging the socket and the second element from separating from the first element.
- the device comprises an elastic means
- the groove comprises a closed end opposite the first element
- the elastic means is positioned in the groove between the slider and the closed end, in such a way as to keep the slider in contact with the top surface of the first element when the device is closed.
- the socket and the head have a taper in a direction that goes from the top surface to the bottom surface of the first and/or second element.
- a cover or an external containment casing having a U-shape, covering the first element, the second element and the slider, can be included.
- the casing or the cover can be integral with the slider, in such a way that their displacement caused by an external force causes the slider to slide inside the groove.
- a guide can be provided inside the slider, in which a pin is housed which is integral with the second element, in such a way that a horizontal movement of the casing causes the slider to slide inside the groove.
- the joint between the socket and the head is of the dovetail type.
- the recess can also be obtained, according to alternative embodiments, between the two bottom and top surfaces of the first element.
- Figure 1 is a perspective exploded view of an embodiment of the fastening device for jewellery according to the invention.
- Figures 2A and 2B are perspective views of the device of Figure 1 in a closed configuration
- Figures 3A and 3B are perspective views of the device of Figure 1 in an open configuration
- Figure 4 is a perspective cross section view along the plane A-A visible in Figure 2A;
- Figures 5A and 5B are detailed views of a second embodiment of the device according to the invention.
- Figures 6A and 6B are perspective partial cross section views of the first embodiment of the device according to the invention.
- the accompanying drawing show an embodiment of the fastening device 1 according to the invention, comprising a first element 10 and a second element 20, each having a body having a substantially prismatic shape.
- the first and second elements 10, 20 are fixed to the respective ends of a bracelet or chain (not shown), and can be joined by means of a dovetail joint.
- the actual coupling consists of a head 201 formed on the second element 20 and a socket 101 formed on the first element 10, complementary to each other in such a way that the head 201 engages the socket 101 .
- Each element 10, 20 has a respective top surface 1 10, 210 and bottom surface 120, 220.
- the profiles of the socket 101 and of the head 201 are laterally tapered, in order to facilitate their insertion and removal, as will be described in detail below.
- this recess 102 is delimited by the top surface 1 10 of the first element 10 itself, in such a way that it is visible only by observing it from the bottom surface 120.
- the recess 102 is included between the top surface 1 10 and the bottom surface 120 of the first element 10.
- a substantially rectilinear groove 240 is formed in a longitudinal direction, provided with an open end facing towards the first element 10, while in the other end there is a blind wall 203.
- a slider 40 is slidably housed together with a spring 60.
- the slider 40 has a tooth 402 ( Figures 3A and 3B) and a relief 403, each at its respective ends.
- the tooth 402 faces the first element 10 protruding from the groove 240.
- the relief 403 acts as an anchor point for the first end of the spring 60 on the slider 40, and the wall 203 acts as an anchor point for the second end of the spring 60 on the second element 20.
- a guide 401 is formed in the central body of the slider 40, to allow the sliding of a pin 50 relative to the slider 40 itself.
- a casing 30 can be included.
- the pin 50 is integral with the second element 20, and is inserted in the guide 401 and inside the casing 30 through a hole 350, formed on a side wall of the casing 30 itself.
- the second element 20 has a cylindrical housing 250 inside its body in which the pin 50 is positioned after insertion.
- the housing 250 is positioned transversely with respect to the groove 240 and passes through, in such a way that the pin 50 can intersect the guide 401 of the slider 40.
- the pin 50 and the guide 401 thus form a prismatic joint, which limits the displacements of the slider 40, allowing only the translation along the groove 240.
- the casing 30 internally comprises a seat 340 in which the slider 40 is housed and which, preferably, acts as a further blockage for the slider 40 itself.
- this slider 40 is made integral with the casing 30, being able to be moved indirectly through an external action exerted on the casing 30 itself.
- the head 201 When the device 1 is in the closed configuration, the head 201 is housed in the socket 101 ; the spring 60 keeps the slider 40 in contact with the top surface 1 10 of the first element 10.
- the casing 30 is connected to the slider 40 and can be moved only together with it.
- the horizontal displacement of the two elements 10 and 20 therefore occurs simultaneously with a reciprocal vertical displacement, due to the inclination of the side surfaces in contact with the socket 101 and the head 201.
- the slider 40 prevents the vertical displacement of the two elements 10 and 20, thus preventing accidental or unwanted detachment.
- the tooth 402 housed inside the recess 120, is pushed in contact with the top surface 1 10 of the first element 10 by the spring 60, and physically prevents detachment from the second element 20.
- the slider 40 To allow the separation of the elements 10 and 20, and, therefore, the opening of the device 1 , the slider 40 must be moved towards the wall 203 of the groove 240 and the spring 60 must be compressed.
- the casing 30 is set in motion by a force exerted by the user, and the same force is transmitted, through the slider 40, to the second element 20, inducing its separation from the first element 10.
- the head 201 is inserted in the socket 101 and a slight pressure is applied.
- the tooth 402 of the slider 40 encounters the opposition of the top surface 1 10 of the first element 10, which pushes it against the spring 60 and towards the wall 203 of the second element 20.
- the device 1 adopts the closed configuration.
- the fastening of the device 1 can take place only if the insertion of the head 201 into the socket 101 takes place from the side of the top surface 1 10 of the socket 101 itself.
- Both the closing operation and the opening operation can be performed with a single hand, therefore in an easy and simple way with respect to the prior art.
- buttons or other systems which can sometimes be operated involuntarily makes the device according to the invention safer than the prior art.
- the casing 30 which covers the other components of the device 1 can have an aesthetic as well as functional value, unlike prior art systems.
