The invention relates to jewelry, in particular to ring designs with improved characteristics of their placement and movement on the finger, and can be used in the manufacture of rings and engagement rings. The ring contains a hoop base with outer, inner and side surfaces. The inner surface is a junction of two arc-shaped cross-section surfaces that are roundly mated to the lateral surfaces of the hoop base. The hoop base can also be equipped with a frame with a jewel placed in it. To create a ring (preferably a ring), convenient for long wearing, the configuration of which would ensure its easy removal, donning, and centering of the rim with the precious stone on the finger, the arcuate surfaces are made with different degrees of curvature and smoothly articulated among themselves. An arcuate surface that has a smaller degree of curvature in cross section can be formed with a portion of concave curvature. At least one elliptical or spherical abutment is located on the opposite side of the hoop base.

DESCRIPTION OF THE INVENTION

(EN) The invention relates to jewelry, in particular to rings for wearing on a finger with improved characteristics of their placement and movement on the finger, and can be used in the manufacture of rings and engagement rings.

A ring design is known which comprises a hoop base with outer, inner and side surfaces, and its inner surface is a junction of two convex arcuate cross-sectional surfaces that are symmetrically disposed on both sides of the symmetry plane of the hoop base, are roundly mated to its lateral surfaces and joined together Between each other, forming a rounded face (chamfer) at the junction, ( see US Patent No. 5606873, cl. A 44 C 9/00, pub., 04.03.1997 ).

The aforementioned design of the ring selected as a prototype has certain advantages with respect to typical designs with a flattened inner surface of the hoop base, which, as a rule, are quite heavily removed from a finger without lubrication (which is especially true for wide rings). Rounded mating of arcuate surfaces of the hoop base with its lateral surfaces increases comfort when wearing 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 point of its transition to the palm. When wearing such a ring, there are inconveniences caused by both the presence on the inner surface of the hoop base of the rounded face formed by the non-smooth conjugation of arc-shaped cross-sections in the cross section, and also because its configuration does not correspond to the asymmetric profile of the inner surface of the finger base.

The task underlying the proposed invention is the creation of a convenient, long-wearing design of the rings (preferably rings), which would ensure their easy removal, donning, and centering on the finger of the rim with the precious stone.

The solution of the stated task (technical result) for a ring worn on a finger comprising a hoop-shaped base with outer, inner and side surfaces in which the inner surface is a connection of two arcuate cross-sectional surfaces roundly mated to the lateral surfaces of the hoop base, In that the arc-shaped surfaces are made with different degrees of curvature and smoothly articulated among themselves. The solution of the problem is also achieved by the fact that the arcuate surface with a lesser degree of curvature in cross section is made with a section of concave curvature, and also in that in the hoop-like base, which is equipped with a frame with a jewel placed in it, with the opposite rim of the side of the hoop base, At least one ellipsoid or spheroid-like stop.

An essential distinctive feature of the proposed invention is the execution of the inner surface of the hoop base of the ring in the form of smoothly connected arcuate surfaces with different degrees of curvature. Given the asymmetry of the finger profile at the location of the ring (the area where the finger of the finger is joined to the palm), that part of the inner surface of the ring that is farther from the palm, covers the thickened part of the base of the finger (which is especially characteristic of wide wedding rings) , Which borders on the palm (hollow). Since the more difficult procedure is the removal of the ring from the finger, the decrease in the curvature of the inner surface at the point of engagement of the thickened part of the finger by the hoop base reduces its pressure on the phalanx. In practice, a more comfortable feeling when using wide rings is achieved by performing a part of the inner surface of the hoop base, which has a lower degree of curvature in the cross section, with a segment of alternating curvature (with negative, i.e., concave) curvature of the surface.

Performing on the opposite side of the hoop base of the ellipsoid or spheroidal abutment makes it easier to remove and put on the ring, and also makes it possible to center the rim with the precious stone on the outside of the palm with the thumb of the same hand. Therefore, this feature is optional. In some cases of the constructive solution, it is advisable to perform two ellipso- or spheroid-like stops, which are located next to each other.

The proposed technical solution is explained on the drawings:

FIG. 1 shows an embodiment of the inner surface of the ring base ring in the form of smoothly interconnected arcuate surfaces with different degrees of positive (convex) curvature.	FIG. 2 is a cross-sectional view of a hoop base for an embodiment of an arcuate surface with a section of alternating (concave) curvature. FIG.
FIG. 3 shows the arrangement of a ring with an alternating curvature of the inner surface of the hoop base in the region of the finger cavity.	FIG. 4 shows an embodiment of a ring base ring with a section of alternating (concave) curvature on its inner surface and an ellipse-like stop. FIG.
FIG. 5 shows a ring with an ellipse-like stop, a rear view	FIG. 6 shows an embodiment of the ring by two spheroidal abutments

The ring consists of a hoop base 1 with an outer 2, an inner 3 and side 4 surfaces. The inner 3 surface of the hoop base 1 consists, in turn, of arched two arcuate cross-sectional surfaces with a greater degree of curvature 5 and with less curvature 6. The ring-shaped base 1 of the ring is equipped with a rim 7 with precious stone 8. On the opposite side of the rim 7 side The ellipsoid 9 or the spherical 10 stop is located on the hoop base. In some cases of implementation, two abutments arranged side by side can be made ( FIG . 6 ).

In order to put the ring on, it is placed with a side with an inner surface that has a large degree of curvature toward the base of the finger, and holding the thumb and index finger of the other hand beyond the outer surface of the hoop base is pushed onto the finger, carrying out minor oscillatory movements around the axis of the hoop base. In this case, part of the inner surface, which has a lesser degree of curvature, more comfortably covers the thickened part of the base of the finger. Centering the rim with the precious stone is carried out by means of the thumb, pressing with lateral force onto an ellipsoidal or spheroid-like stop. Removal of the ring from the finger is carried out in a similar way, while the relief of removal is provided by the gradual influx of its inner surface onto the thickened portion of the phalanx of the finger and its subsequent crimping of the inner surface of the ring with a lesser degree of curvature.

The claimed technical solution is realized on standard equipment of jewelry production using known technological processes.
