Abstract

FIELD: jewelry articles, in particular, construction of rings, more particular, production of wedding rings.

SUBSTANCE: ring has band base with outer, inner and side surfaces. Inner surface is made in the form of two connected surfaces having arcuate cross-section and joined in rounded manner with side surfaces of band base. Band base may be also furnished with rim having precious stone mounted therein. For creating ring construction convenient for prolonged wearing and configured to provide easy removal and putting thereof, as well as centering of rim with precious stone on finger, arcuate surfaces have various curvature extent and are smoothly joined with one another. Arcuate surface with smaller curvature extent of its cross-section may be equipped with portion having concave curvature. At least one elliptic or spherical stop is positioned at side of band base opposite to rim.

EFFECT: improved characteristics of arrangement and displacement on finger.

Description

The invention relates to jewelry, in particular to designs of rings to be worn on the finger with improved characteristics of their placement and movement on the finger, and can be used in the manufacture of rings and wedding rings.

A known design of the ring, which contains a hoop base with external, internal and side surfaces, and its inner surface is a connection of two convex arcuate in cross section of surfaces that are symmetrically located on both sides of the plane of symmetry of the hoop, are rounded in conjunction with its side surfaces and are connected between each other, forming a rounded edge (chamfer) at the junction, (see US patent No. 5606873, class A 44 C 9/00, publ. 03/04/1997).

The aforementioned ring design, selected as a prototype, has certain advantages in relation to typical designs with a flattened inner surface of the hoop base, which are usually quite difficult to remove from the finger without lubrication (which is especially typical for wide rings). The rounded conjugation of the arched surfaces of the wedding base with its side surfaces increases the comfort when wearing the rings and facilitates their removal from the finger. But this technical solution does not take into account the characteristic asymmetry of the configuration of the inner surface of the base of the finger at the place of its transition to the palm. When wearing such a ring, inconvenience arises due to both the presence on the inner surface of the hoop base of a rounded face formed by smooth conjugation of arched surfaces in the cross section, and the fact that its configuration does not correspond to the asymmetric profile of the inner surface of the finger base.

The task underlying the present invention is to create a ring structure (mainly rings) that is convenient for long-term wearing, which would also ensure their easy removal, donning, as well as centering on a finger of a frame with a precious stone.

The solution of the problem (technical result) for a ring worn on a finger containing a wrap base with external, internal and side surfaces, in which the inner surface is a connection of two arched in cross section surfaces that are rounded in conjunction with the side surfaces of the wrist base, according to the invention is provided the fact that the arcuate surfaces are made with varying degrees of curvature and smoothly interconnected. The solution to the problem is also achieved by the fact that the arcuate surface with a lower degree of curvature in cross section is made with a concave curvature section, and also in the case of a hoop base, which is equipped with a frame with a precious stone placed in it, located on the opposite side of the frame of the hoop base, at least one ellipse or sphere-like emphasis.

An essential distinguishing feature of the invention is the implementation of the inner surface of the hoop base of the ring in the form of smoothly interconnected arched surfaces with varying degrees of curvature. Given the asymmetry of the finger profile at the location of the ring (the area where the finger base joins the palm of the hand), the part of the inner surface of the ring that is further from the palm more densely covers the thickened part of the finger base (which is especially characteristic of wide wedding rings) than the part of the inner surface that borders the palm (hollow). Since the process of removing the ring from the finger is a more difficult procedure, the decrease in the curvature of the inner surface precisely at the place where the thickened part of the finger is covered by the hoop base reduces its pressure on the phalanx. In practice, a more comfortable feeling when using wide rings is achieved by performing part of the inner surface of the hoop base, which has a lower degree of curvature in the transverse section, with a portion of an alternating (with negative, i.e. concave) curvature of the surface.

Performing on the opposite side of the rim of the engagement base of the ellipse or sphere-like emphasis facilitates the process of removing and putting on the ring, and also makes it possible to center the rim with a precious stone on the outside of the palm of the hand using the thumb of the same hand. Therefore, this feature is optional. In some cases, a constructive solution, it is advisable to perform two ellipse or sphere-like stops, which are located next to each other.

The proposed technical solution is illustrated in the drawings:

Figure 1 - embodiment of the inner surface of the hoop base of the ring in the form of smoothly interconnected arched surfaces with varying degrees of positive (convex) curvature.

Figure 2 is a cross section of a hoop base for an embodiment of an arched surface with a portion of alternating (concave) curvature.

Figure 3 - placement of the ring with alternating curvature of the inner surface of the hoop base in the region of the depression of the finger.

Figure 4 is an embodiment of a hoop ring base with a section of alternating (concave) curvature on its inner surface and an ellipse-like stop.

5 is a ring with an ellipse-like emphasis, rear view.

6 is an embodiment of the ring with two sphere-like stops.

The ring consists of a wedding base 1 with outer 2, inner 3 and side 4 surfaces. The inner 3 surface of the engagement base 1 consists, in turn, of two arched surfaces with a greater degree of curvature 5 and less curvature 6. The engagement base 1 of the ring is equipped with a frame 7 with a precious stone 8. On the opposite side of the frame 7 the hoop base is an ellipse-like 9 or sphere-like 10 emphasis. In individual cases, the implementation can be performed two stops located next to (Figure 6).

To put on the ring, it is placed with a side with an inner surface that has a greater degree of curvature towards the base of the finger, and, holding the thumb and forefinger of the other hand on the outer surface of the hoop base, is pulled over the finger, making slight oscillatory movements around the axis of the hoop base. Moreover, a part of the inner surface, which has a lesser degree of curvature, more comfortably covers the thickened part of the base of the finger. The centering of the gemstone frame is carried out by means of the thumb, pressing with an lateral force on an ellipse or sphere-like emphasis. The removal of the ring from the finger is carried out in a similar manner, while the removal is facilitated by the gradual influx of its inner surface onto the thickened portion of the phalanx of the finger and its subsequent compression by the inner surface of the ring with a lesser degree of curvature.

The claimed technical solution is implemented on standard jewelry manufacturing equipment using well-known technological processes.
