Description

[Detailed description of the invention] This invention relates to a ring suitable for both decorative and health purposes.

In conventional rings, the inner hole of the ring, that is, the inner circumference of the ring is circular, and it is often difficult to remove the ring from the finger because of the presence of the finger joint. In addition, sometimes the ring cannot be removed from the finger and the ring has to be amputated, which is especially a problem if the ring is expensive.

Also, when purchasing a ring, the purchaser must first measure the thickness of the finger using a gauge and select a ring that matches this. If the ring diameter is different, the ring may be too tight and the ring may feel uncomfortable, or it may be too loose and the ring may wind around the finger, making it impossible to minimize the tolerance in the dimensions of the inner hole of the ring.

The purpose of this invention is to overcome the above-mentioned drawbacks and provide a ring that is easy to put on and take off from the finger, has good wearability, does not easily come off, and has a generous inner hole dimension. It is in.

A ring according to an embodiment of this invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the ring 1 has two mutually separated first and second ring members 2,3. These members 2 and 3 are made of precious metals such as gold, silver, and platinum when used for decoration, and are made of permanent magnets when used for health purposes, and have the same shape. As shown in FIG. 2, each ring member has a bore 4 into which a finger is inserted, which has a regular hexagonal cross section, and a circular external appearance. This regular hexagonal bore 4 has a circular portion 5 located at the center,
6 protruding from both sides at a predetermined distance from each other.
It consists of three triangular parts 6. The diameter of the circular part 5 is the height of the joint of the finger to be inserted (i.e., the small diameter of the joint)
are set almost the same. On the other hand, the diameter of the circular part 5 plus the width of the triangular part 6, that is, the length of the diagonal of the hexagon, is set to be approximately the same height as the width of the joint of the finger to be inserted (that is, the long axis of the joint). The circular portion 5 constitutes a main bore portion, and the triangular portion 6 constitutes an auxiliary bore portion.

Both ring members 2 and 3 are provided with means for connecting them to each other and restricting relative movement in the axial direction, on sides facing each other. This means is constituted by permanent magnets 7, 8 embedded in the opposing end faces 2a, 3a of the ring members 2, 3, respectively.

The case in which the ring having the above structure is put on the finger and the case in which it is removed from the finger will be explained below with reference to FIGS. 3 and 4.

The first ring member 2 is moved in the direction of the arrow as shown in FIG. 3 with the end surface 2a provided with the permanent magnet facing upward, and is inserted into a predetermined location on the finger. At this time, by inserting the ring member 2 into the finger so that the long axis of the finger joint and the diagonal of the bore 4 match, and the short axis of the former matches the diameter of the circular part of the latter, smooth insertion can be achieved. is achieved. Next, the second ring member 3 is similarly inserted into a predetermined location on the finger with the end surface 3a provided with the permanent magnet facing down.
After inserting this second ring member 3,
After rotating this member 3 by a predetermined angle, for example 30 degrees, the permanent magnet 7 is attached to the first ring member 2.
They are integrally connected via 8. As a result, the regular hexagonal bores 4 of each ring member are shifted by a predetermined angle relative to each other, as shown in FIG. Thus, the effective area of the ring bore is equal to the area of the overlapping portion of both regular hexagonal bores 4, and the opening area of the regular hexagonal bore 4 is smaller at the auxiliary bore portion 6. For this reason, the ring is prevented from coming off at the joint.

When removing the ring, the ring members 2 and 3 are disengaged by the magnets 7 and 8, and the second ring member 3 is rotated to the same position as when it was inserted. In such a state, the regular hexagonal bores 4 of the first and second ring members 2 and 3 and the cross sections of the joint portions substantially match, so that they can be easily removed.

Although two ring members are used in the ring of the above embodiment, the number of ring members is not limited to this, as long as there is a plurality of ring members, and for example, three may be used as shown in FIG. 5. In this case, the third ring member 10 interposed between the first ring member 2 and the second ring member 3 has both ends 1
It is necessary to provide engaging portions 11a and 11b at 0a and 10b, respectively. In this example, the engaging parts 11a, 11b
is constituted by one ring-shaped permanent magnet, but may be constituted separately. Even in a ring composed of three ring members, it is possible to prevent the ring members from slipping off the finger by attaching each ring member separately to the finger and rotating one or two of them at a predetermined angle relative to each other. can be prevented.

In the above embodiment, a ring member having a regular hexagonal bore was described, but the shape of the bore may be any shape other than a perfect circle, for example, other polygonal shapes or patterned shapes. The combination of bores may be of the same shape or of different bores. 6th
In the ring shown in the figure, the bore 4 has a cherry blossom petal pattern shape, and the circular main bore part 5 is located in the center.
and five auxiliary bore portions 6 protruding from the main bore portion 5 in the shape of petals.

Also in the ring member shown in Fig. 6 above,
By utilizing the auxiliary bore portion 6, it is easy to insert and remove the finger from the finger, and by rotating the ring members relative to each other and then engaging them, the ring member is prevented from coming off from the finger.

In the above explanation, the case is explained in which permanent magnets are used as means for connecting or engaging the ring members with each other, but the present invention is not limited to this, and there may be other means such as fitting means, hook means, engaging means using unevenness, etc.
Any material may be used as long as it prevents the ring members from moving relative to each other in the finger or axial direction.
