Description

DESCRIPTION

Extendable ring

TECHNICAL SECTOR

The present application refers to a ring, of the type used in jewelery or costume jewelery, which can vary its internal diameter at the discretion of the owner or jeweler.

STATE OF THE ART

The use of rings as a decoration or symbol of marital status, among other functions, is known in the state of the art. It is applicable to all kinds of rings and decorations that can be placed on the ring. These rings are usually placed on the ring finger (left or right, depending on the region) and are often kept in position for years.

This causes the hand to grow, swell due to age, osteoarthritis, etc. and it is not possible to remove the ring when desired. Therefore, it cannot be cleaned, treated to improve its finish, repaired ... If it is essential to remove it, it ends up being cut, which destroys the ring.

It is also applicable in solitaires or other pieces whose internal measurement is defined by the passage of the knuckles, which are sometimes swollen. Therefore, the ring needs a large diameter for knuckle passage, but upon reaching the natural position in the proximal phalanx, this excessive size causes the ring to rotate or slide freely. Therefore, the decoration is not in the correct position.

The applicant does not know of any solution similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of an extensible ring according to the first claim. Its different variants solve the problems outlined.

The extensible ring is formed by an annular body that has a cutout. In this section, at least one first closing arm is articulated by means of an axis perpendicular to the inner surface of the annular body and with a locking system in the closed position.

The locking system can be of many forms, some compatible with each other. For example, it can be a removable pin with tools that goes through the arm and the annular body. It can also be due to temporary deformation of an elastic element. The first system is more definitive, while the second is easier to release.

To increase the dimensions of the cut, it can also comprise a second articulated arm that can be coupled to the first arm. In this way, the two arms lock together to define the smallest position of the ring.

In this case, each arm is preferably divided into two sections, the end sections being inserted one inside the other in the closed position. One of the end arms may have a channel through which a cylinder attached to the tip of the other end section slides, so that the two arms are not disengaged in the open position.

In one embodiment, compatible with that of the channel, the end section of the first arm is formed by two parallel bars finished off in a bulge. In turn, the end section of the second arm is formed by two plates that hug the end section of the first arm and each have notches for the introduction of the bulges. This system defines a fixing by clipping.

Other variants are appreciated in the remainder of the specification and are defined in the dependent claims.

DESCRIPTION OF THE FIGURES

For a better understanding of the invention, the following figures are included.

Figure 1: View of a first embodiment, in open or extended position (A) and closed (B).

Figure 2: View of a second example, with two arms.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

The embodiment shown in the figures starts from a metallic annular body (1), with or without gems, precious stones or other decorations. The annular body (1) has a cut in one area, where at least one first arm (2) is articulated by means of a rod (3) that acts as the axis of the first arm (2) so that it can move outwards. The stem (3) is consequently perpendicular to the inner surface of the annular body (1).

The first arm (2) has a locking system to keep it in the closed position. It can be by "clipping" or temporary deformation of an elastic element, or by the use of a pin (4) that is removable by means of tools. That pin (4) would be flush with the annular body (1) so as not to spoil the aesthetic appearance.

The most preferred solution is shown in the embodiment of figure 2. It comprises two arms (2,5) articulated to the annular body (1) and in turn separated into two sections (21,22,51,52). The inner sections (21,51) are similar to each other, while the end sections (22,52) are coupled to each other, so that in the coupled position they are inserted one inside of the other. Figure 2 shows how the end section of the second arm (51) is formed by two parallel plates finished off in a bulge (23). This end section of the second arm (52) embraces the end section of the first arm (21) which has respective notches (53) for the introduction of the bulges (23). When the bulges (23) are in the notches (53) the ring is closed, in the smallest position. When it is extracted, by temporary deformation of the end section of the second arm (51), the ring takes on a larger size. Some projections, represented as balls, help to carry out this movement.

The bulges (23) and the notches (53) may actually be on the innermost or outermost plates. Likewise, the plates can be inserted, but it is less preferred since the way of arranging these elements is more complex.

In this figure 2 a channel (54) can be seen in the end section of the first arm (22) that limits the relative movement of the second arm (5), which is integral in sliding to a cylinder (24) that slides through the channel ( 54).

The arms (2,5) of the ring, and therefore the cut, must cover an appreciable part (generally at least 80 °, and preferably at least 120 °) of the ring to facilitate the release of the finger, depending on the elasticity of the ring .
