Description

Adjustable Inner Diameter Ring Jewelry

technical field

The present invention relates to a generally ring-shaped jewellery, especially a ring, comprising a first portion and a second portion, each of which is approximately a portion of a ring and has a first end and a second end respectively. The first part and the second part are connected to each other by a pivot type connection means, and by different depths of nesting, the first end of each part is adapted to cooperate with the first end of the other part, thereby defining an adjustable inner diameter closed loop. Additionally, at least one elastic member is adapted to act on the two locations such that the first ends of the two locations tend to nest one within the other to reduce the inner diameter of the jewellery.

The invention also relates to the manufacture of a bracelet of the character described above.

Background technique

Jewelry of this type has been disclosed in the past, for example in patent application CA2393992A1. This application describes a ring having two parts, the parts being assembled to each other at a first end by means of a pivot type connection. Their second ends fit in a nested fashion and have complementary detents to hold them in a given position after ring diameter adjustment.

However, it should be noted that, from an aesthetic point of view, the structure described above has the disadvantage of not being able to conceal the two connections provided between the two ends of the two parts of the ring.

Also, the fixed adjustment approach can prove somewhat impractical and requires trial and error. In addition, the available adjustment positions are limited, and the diameter of the ring wearer's finger cannot completely match the preset position when the ring is made.

Patent KR 100803518 B1 describes a ring with the above-listed features, in which the two side parts are mutually pivoted at a first end and are housed in a third central part at its second end, supporting a decorative element. However, the depth of nesting of these various parts is visible, which has a non-negligible effect on the aesthetics of the ring, as is the pivot-type connection means connecting the two side parts.

Contents of the invention

The main purpose of the present invention is to remedy the drawbacks of the adjustable jewelry known in the prior art, by proposing such a jewelry that simultaneously meets the aesthetic requirements of high-end products and the requirements of comfort in use, especially with regard to the adjustment of its inner diameter.

Therefore, the present invention relates in particular to a piece of jewelry of the above-specified type, characterized in that the pivotal connection means are located at a distance from the second end of the first part, the second end having a covering part positioned at the Between the pivot type connection means and the second end, the covering portion has a larger radius than the inner portion facing said second location where it is located, so that it is at least partially covered.

Based on the above features, the jewelry sample made according to the present invention firstly has a certain number of adjustment positions. Taking a ring as an example, when worn on a finger, the adjustment of its inner diameter is implemented in a dynamic manner. In fact, under the action of the elastic member, the rest positions of the two parts correspond to the minimum diameter that the ring can present. When the finger wearing the ring is larger than this minimum diameter, the force exerted by the finger on the two parts of the ring is opposite to that of the elastic member. Apply force to increase the inner diameter of the ring so that it is just larger than the size of a finger.

In addition, especially due to the fact that said pivot connection means are hidden, the change in appearance of the jewelry according to the invention as a function of the inner diameter is hardly perceptible.

Preferably and advantageously, the elastic member acts on the one hand in the covering area of the first area and on the other hand in the interior of the second area.

According to a preferred embodiment, one of the first and second parts is provided with a groove, in which the elastic member is arranged, and the other of the first and second parts is provided with a finger with a free end, which is connected with the elastic member. components offset.

Based on the above features, the superior functionality of jewelry made according to the present invention can be utilized without any detrimental effect on the aesthetics of the finished product.

In particular, the first region may comprise a decorative element extending at least partially over the covering region.

In addition, it is also possible, at least in the first region, that the width of the region of its second end is greater than the width of the region of its first end in order to define a position for the decorative element.

In addition, the first end of one of the first part and the second part may have a sliding piece, which cooperates with the groove in the first end of the other of the first part and the second part, so as to be able to slide therein.

A preferred embodiment of the invention includes the manufacture of a ring having the features specified above. Alternatively, the invention is also applicable to the manufacture of bracelets having the above-specified characteristics.

Description of drawings

Other characteristics and advantages of the present invention will become more clearly understood by reading the following detailed description of preferred embodiments, by way of non-limiting example, and with reference to the accompanying drawings, in which:

Figure 1 shows a simplified perspective view of a ring according to a preferred embodiment of the present invention from a first viewing angle;

Figure 2 shows a simplified perspective view of the ring of Figure 1 from a second viewing angle;

FIG. 3 shows a simplified cross-sectional view of the ring of FIG. 1 .

Detailed ways

From a first perspective and a second perspective, Figures 1 and 2 show simplified perspective views of a ring 1 with adjustable inner diameter according to a preferred embodiment of the present invention, so that certain structural details can be understood. Figure 3 shows the same ring 1 in transverse section, so that some of its details can be understood.

The ring 1 comprises two main parts, a first part 2 and a second part 4, which are roughly shaped as respective opposing sections of a circular ring.

There is a pivot-type mechanical connection device between the first part and the second part, which is determined by the cooperation between the two pivots 6 included in the second part 4 and the support 8 provided in the first part 2 .

Of course, the use of pivotal connections is illustrative and not limiting of the invention. Those skilled in the art will encounter no particular difficulties in implementing alternative solutions, such as changing the position of the pivot and the abutments, or using a single tie rod, each end housed in one of the abutments.

It should also be noted that the pivots and standoffs are shown for ease of understanding, but preferably the standoffs do not pass through the wall of the first part 2 so that they are not directly visible on the ring, thereby improving the aesthetics of the ring .

Additionally, the first portion 2 has a first end 10 and a second end 14 , and the second portion 4 has a first end 12 and a second end 16 .

Said first ends 10, 12 are substantially complementary in shape to enable them to co-operate with each other by at least partially nesting of different depths when the first portion 2 and the second portion 4 are mutually pivoted about each other to form a Closed ring with adjustable inside diameter.

Further, by way of non-limiting example, each first end 10, 12 has a groove through its thickness for co-operating with a substantially complementary slide of the other end, and a slide tab for cooperating with a complementary groove provided at the other end.

Here, the special shapes of the first part 2 and the second part 4 are not restrictive. In particular, its width increases in a direction from the first end 10 , 12 towards the second end 14 , 16 . The width of the first portion 2 additionally enables the definition of a location 18 , here in the form of a recess, for accommodating a decorative element (reference number 19 in FIG. 3 ), such as a jewel.

The second end 16 of the second part 4 comprises two struts 20 extending in the direction of the first part 2 , each supporting a pivot 6 .

It is clear from the figure that the pivotal connection means are located at a distance from the second end 14 of the first portion. In fact, the pivotal connection extends beyond the second end 16 of the second portion 4 so as to comprise a covering portion, ie so as to cover an inner portion of the second portion 4 .

In addition, the second end 16 of the second part 4 also includes a wall-engaging finger 22 , here in the form of a cylindrical tube 24 , fixed to the first part 2 .

Resilient members (visible in FIG. 3 ), such as helical springs 26 , fit in the bottom of the barrel 24 in order to exert a force on the fingers 22 intended to push them out of the barrel 24 . Thus, the elastic member exerts a relative force on the first part 2 and the second part, urging the first ends 10, 12 of the first part 2 and the second part 4 to approach each other, ie in this way the depth of their engagement is increased. In other words, the elastic member always tends to reduce the inner diameter of the ring 1 such that when the ring is not being worn, the inner diameter is smallest.

Based on the specific structure of the ring in the present invention, a ring can be obtained, the inner diameter of which can automatically and instantaneously match the size of the wearer's finger, and the wearer does not need to perform any special operations. In addition, since the change in diameter is continuous, the inner diameter is precisely adapted to the diameter of the finger on which the ring is worn, as opposed to the inner diameter of the prior art rings discussed above.

It should be noted that the mechanism shown by the fingers 22 and the barrel 24 makes it possible to define a stop when the first portion 2 and the second portion 4 move away from each other, i.e. when the internal diameter of the ring 1 increases, which avoids Accidental disassembly of the ring.

Of course, it is possible to interchange the respective positions of the fingers and cylindrical barrel 24 without departing from the scope of the invention.

In the same way, the first ends 10, 12 define a stop relative to a value below the inner diameter of the ring.

By way of non-limiting illustration, the above description is intended to describe a preferred embodiment, and the invention is not limited to the use of certain specific features just described, such as the specific shape shown and describe. In practice, the resilient member may be located at any suitable location between the pivot-type connection and the second end 14 of the first portion 2 .

It will be noted, however, that the shapes shown for the first and second locations provide the advantage of facilitating the pivoting connection means and the covering of the various components ensuring mounting of the resilient member.

Without departing from the scope of the present invention, those skilled in the art will not encounter any difficulties, according to their own needs, apply the disclosed content of the present invention and make jewelry with adjustable inner diameters having only some of the above-mentioned technical features. Of course, the invention is not limited to rings, but can be used for all other jewelry compatible with the invention, such as bracelets.
