Abstract

A fastener comprises a female part composed of two portions 1 and 2 hinged together and provided with an internal spring 20, which biases the fastener closed. A male part 15 can be inserted between the internal faces of the portions 1 and 2 which faces have formations 13, 14 for the guidance and automatic retention of the male part 15. The leading edge 16 of the-male part is preferably bevelled, as is the retaining protrusion 14 on the inner face of the female part 2. The female part is opened by means of finger and thumb pressure at the position of the arrows in fig. 4, behind the pivot and against the force of the spring.

The present invention concerns a clasp for necklaces, bracelets and other jewelery and bijouterie items, α which is of the type formed by two parts, one female and the other male, conveniently connected to the terminals of the corresponding jewelery or jewelry item, which are essentially characterizes that the female component of the closure is made of material, with variable shape and dimensions, subjected to the tension of an internal spring which, in the resting phase, keeps this device closed, with the appearance of appropriate means for entry, guidance s automatic retention of the male element, which consists of a plate with a suitable profile which, like one of those two pieces of the female element, has a washer for fitting to the ends of the jewelery or jewelery to be closed »

The present invention concerns & a new clasp for necklaces, bracelets and other articles of jewelery and bijouterie, which offers several and important technical peculiarities with respect to the known executions for a clasp with the same purpose. In addition, the structure of this clasp allows the application of ornamental elements that form a set with the corresponding piece of jewelery or bijouterie, and, with regard to è. security of the latter ,. eia is guaranteed by the adoption of an effective fitting system, established in the two parts (male and female) constituting the said device.

In the branch of jewelery and costume jewelery, several types of male-female clasps are known for the aforementioned purpose, all of which are based on the same functional and constructive principle. Its female component is rigid and provided with a simple cavity within it, into which the male component penetrates and is inserted, provided with elastic means which, by reaction, must ensure mutual retention. Unfortunately, this is not always reliable, since the moles effect of the male element is lost with use, α which causes the involuntary disarticulation of the closure, with the resulting inconveniences.

The mentioned problems are totally solved with the closure object of this invention, which is also of an interlocking type, being characterized by the female component of the closure being made up of two pieces whose material, shape and dimensions are variable, preferably with equal contour, which fit together through a hinge-type joint and are subjected to the tension of an internal spring which, en? the resting phase, keep this device closed, appearing on the inner face of such pieces two medium pieces, suitable to allow the entry, guidance and automatic retention of the male element, constituted by a small, plate with an adequate profile, which would be opportune ΐ

washer, to fit at one end of the or. jewelery to close.

In order to better understand the present specification, a set of drawings is attached in which, just as a non-limiting example m-as, a practical case of execution of a closure with the mentioned aerial characteristics is represented.

Of those drawings:

a Fig. 1 gives a cross-sectional view of the components of the female element of this fastener?

Figure 2 corresponds to a plan view, of the previous figure, to which the male element of this same closure has been added?

the hygiene -3 represents a side view of the device of this invention, being it closed?

illustrates hygiene 4 is an enlarged view of a section, which, aramenis the internal composition of said closure.

object of presence female part (figure i>, which adjustable flat parts (1) and contour and equipped with both with which it can be inserted and adornment element ¢ 5) and (ó), thin or similar, as shown ρ1ιada 4 »and invention consists of one in turn consists of two (2) ₃ preferably with equal one outside cavity) and (4), conveniently fix any being a pearl, a stone can see in detail of the figure

On the opposite or internal side, the parts Clí and (2) themselves have ribs (7) and <8), the first having holes (9) and the second having internal pins <íOí, as can be seen in Figure 2, this whole set constituting a hinge-type joint in the referred female part »

One of the aforementioned pieces, for example a (1), has an extreme washer Clí>, and on the hollow internal face (which is opposite the aforementioned adornment) it has a fitting (12) and longitudinal guides (13) =. The other piece. (2), it also has a protrusion or stop (14) on its inner face,

4) a sharp edge »male component (figure 2) consists of a small fork-shaped plate (15), a. which has a beveled edge fitting.do (16), a hole C17) corresponding to the stop (14), and a washer (18) which, like the (11), can be attached to one end of the necklace, bracelet or similar, these being represented by dashed lines C19) „

As an elastic means to close and open this device, you have opted into the socket (12) (figure 4) and in the resting position, keep the visi ve1 in the 3 # (figure 1), which is mounted is oriented so to which, when pressed, what is □ the functioning of the described lock can be summarized in the following points?

by means of the spring (20) does the device remain closed by lever effect (figure 3), since the expanding pressure is exerted on the opposite part of the entrance of the male element (15)?

In order to insert the latter, to make the fitting, it is done simply by pushing the. plate (15) so that it advances on the guide (13), since the chamfered edge C6) jumps above the bevelled edge of the stop C14) at the entrance to the assembly.

u. by mouth, from said stop (14) enters into the orifice

PÇJÇ;

exerting the effect of a retaining tooth »This allows a perfect fit of the male and female parts of this lock, without the possibility of it opening unintentionally»

The desired opening is very simple, as you only need to apply digital pressure to the back of the closure (see the mutually directed droughts in the figure to overcome the spring tension (20) and release the male plate (15), in order to to be able to easily extract the female part »In this area ·, the opening direction is marked with the opposite arrows of the aforementioned figure 4» the dome can be seen, the retention is perfect ε the closing and opening operations do not present any difficulty for the user, which does not have to pay any attention to the deep fit of the hoe piece with the female piece »nats.

The different shapes and dimensions of the elements that make up the discreet closure will be independent of the objective of the invention, applied to the same one that is applied to secondary elements other than the characteristics of the adornment elements, the type of jewelery or jewelry to the device and other details of character influence its essence »
