Abstract

PROBLEM TO BE SOLVED: To provide a ring which can secure a sufficient clearance between the inner circumference part thereof and a finger without degrading wearing touch. SOLUTION: In the ring 1, bulged parts 2 bulging in a circular arc inward radially are formed circumferentially at a plurality of points, for example, eight points of the inner circumferential part of a ring body 10 at equal intervals of angle. As a result, the border parts between adjacent bulged parts 2 all form grooves 3 recessed outward radially and the grooves 3 are made narrower deeper therein. When the ring 1 is put onto the finger 20, the finger 20 closely contacts the bulged part 2 alone thereby securing the clearance 30 for breathing deeper in the grooves 3.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a ring.

[0002]

2. Description of the Related Art Conventionally, various designs of rings have been available as ornaments, and those who prefer rings with a sense of volume have a width of 4 mm for the ring body 10 as shown in FIG. 3 (A). The above-described ring 1 or a plurality of rings, for example, a ring 1'consisting of three ring bodies 10 as shown in FIG.

[0003]

However, as shown in FIG.
In the rings 1 and 1'shown in (A) and (B), when the inner peripheral portion of the ring body 10 is a perfect circle, the inner peripheral portion of the ring body 10 and the finger 20 are in close contact with each other without a gap. Long term,
As it is used, problems such as skin stuffiness and rash occur. Further, when the wide ring body 10 or a plurality of ring bodies 10 are fitted to the finger 20, a cramped feeling cannot be avoided as compared with the case where a thin ring is fitted. Further, if the inner peripheral portions of the rings 1 and 1'and the finger 20 are in close contact with each other without a gap, the problem that the wide ring 1 or 1'is difficult to come off easily occurs.

Therefore, like the ring disclosed in Japanese Utility Model Laid-Open No. 58-129809, the ring body has a polygonal opening, and the ring disclosed in Japanese Utility Model Laid-Open No. 5-11808 is a ring. A body in which a groove is formed on the inner peripheral surface of the body, which is recessed in an arc shape radially outward, and a small protrusion is formed on the inner peripheral surface of the ring body, such as a ring disclosed in Japanese Patent Publication No. 6-67767. In such a ring, when the ring is fitted on the finger, a certain amount of gap is formed between the inner peripheral surface of the ring body and the finger, so that the skin does not get stuffy and rash. Can be suppressed. In addition, since the area where the inner peripheral surface of the ring body and the finger are in close contact can be narrowed, the same wearing feeling as when a thin ring is fitted can be obtained,
Moreover, there is an advantage that it can be easily attached and detached.

However, in the ring disclosed in Japanese Utility Model Laid-Open No. 129809/58, only the grooves corresponding to the corners of the polygon are formed, so that the inner peripheral surface of the ring and the finger are not separated from each other. There is a problem that it is not possible to reliably prevent the skin from getting stuffy and rash because the groove is filled in between or only a small gap can be formed. Further, in the ring disclosed in Japanese Utility Model Laid-Open No. 5-11808, a corner is formed at the entrance of the arc-shaped groove, and this corner bites into the finger, so that there is a problem that the wearing feeling is poor. Further, in the ring disclosed in Japanese Patent Publication No. 6-36767, there is a problem in that the fitting feeling is poor because the small protruding portion of the inner peripheral portion of the ring body bites around the finger.

In view of the above problems, the object of the present invention is to
(EN) It is intended to provide a ring capable of ensuring a sufficient gap between the inner peripheral portion of the ring and the finger without reducing the wearing feeling.

[0007]

In order to solve the above problems, in the ring according to the present invention, when the opening direction of the ring body is set to the width direction, the inner peripheral portion of the ring body is radially inward. A plurality of projecting portions projecting in an arc shape in the circumferential direction are formed in the circumferential direction, and boundary portions between the projecting portions adjacent to each other are grooves that are recessed outward in the radial direction.

In the ring to which the present invention is applied, the ring body is formed with an overhanging portion that projects inward in the radial direction in a circular arc shape at the inner peripheral portion. The boundary between the two is a groove recessed outward in the radial direction. For this reason, it is the central portion of the arc-shaped overhanging portion of the inner peripheral portion of the ring that fits around the finger when fitted on the finger, and the ring between the finger and the ring is formed by the groove. There is a gap that communicates with the outside in the width direction of the body. Moreover, since the projecting portion projects in a circular arc shape, the width of the groove is narrow at the back of the groove. For this reason, the skin of the finger does not go deep into the groove,
A ventilation gap can always be secured between the inner peripheral surface of the ring body and the finger. Therefore, even if it is used for a long period of time, the problem that the skin becomes damp and has a rash does not occur. Further, since the contact area between the inner peripheral portion of the ring and the surroundings of the finger is small, even if a wide ring is fitted, the same wearing feeling as when one thin ring is fitted can be obtained. In addition, since the contact area between the inner peripheral portion of the ring and the area around the finger is small, the ring can be easily attached and detached.

In the present invention, a portion corresponding to the corner between the inner peripheral surface of the projecting portion and the upper end surface of the ring body, and a corner between the inner peripheral surface of the projecting portion and the lower end surface of the ring body. It is preferable that each part has a curved surface. With this configuration, there is no angular portion,
Excellent fit.

In the present invention, the width of the ring body is 4 mm or more. The width dimension of the ring is not limited, but particularly in the case of a ring having a width dimension of 4 mm or more,
Since the problem due to the large contact area between the finger and the ring is likely to occur, the present invention is particularly effective when applied to such a ring.

Further, the ring according to the present invention may be composed of a plurality of the ring bodies that can be separated from each other, and in this case, the total width dimension of the plurality of the ring bodies is, for example, 5 mm. It is designed above. The width dimension of this type of ring is not limited, but especially in the case of a ring having a width dimension of 5 mm or more,
Since the problem due to the large contact area between the finger and the ring is likely to occur, the present invention is particularly effective when applied to such a ring.
