Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ring suitable for both decorative and health purposes.

Conventional rings often have a difficult time removing them from the finger because of the circular shape of the ring, i.e., the inner circumference of the ring, and 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 his or her finger using a gauge and select a ring that matches this. If the
This had the disadvantage that it was too loose and the ring could get wrapped around the finger, making it impossible to minimize tolerances in the dimensions of the ring.

SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-mentioned drawbacks and provide a ring that is easy to put on and take off from a finger, has good wearability, and does not easily come off.

In order to achieve the above object, the ring of the present invention includes a ring member, a header defined by the inner peripheral surface of the ring member into which a finger can be inserted, and a ring member that protrudes from the inner peripheral surface of the ring member and is inserted into the header. At least two protrusions that can come into contact with the fingers, and the relative positional relationship of each protrusion along the circumferential direction is changed so that the effective area of the fire direction is changed,
Means is provided for making at least one of the protrusions movable along the inner circumferential surface of the ring member between the generatrix where the other protrusion is located and the other generatrix.

When the respective protrusions are located on the same generatrix, the effective area of the direct fire is the largest, and as the respective protrusions are spaced apart from each other, the effective area of the direct fire becomes smaller.

The user of the ring can set the effective area that best suits the thickness of the user's finger by inserting the finger into the ring and moving the protrusion in the circumferential direction to change the effective area. It is possible to prevent it from coming off.

Furthermore, the ring can be easily attached and detached by moving the protrusions to increase the effective area of the fire direction.

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1-4, the ring 10 includes a ring member 12 and a header 16 defined by an inner circumferential surface 14 of the ring member.

When the ring 10 is for decoration, the ring member is made of a precious metal such as gold, silver, or platinum, and when it is for health, the ring member is made of a permanent magnet.

The headlight 16 has a circular shape into which a finger can be inserted, and its inner diameter is set to be slightly larger than the diameter of the thickest part of the finger, for example, the joint part.

The ring member 12 includes a pair of protrusions 18 and 20 protruding from its inner peripheral surface 14, and each protrusion is formed so as to be able to come into contact with a finger inserted into the circular hole 16.

The ring member 12 also includes means for moving at least one of the protrusions 18 and 20 along the inner circumferential surface 14 of the ring member to change the relative positional relationship of each protrusion along the circumferential direction. ing.

This means has an auxiliary plate 22 forming a part of the ring member 12, and the auxiliary plate is arranged approximately parallel to the inner circumferential surface 14 and spaced apart from the inner circumferential surface 14 by a predetermined distance.

Further, the auxiliary plate 22 has a width substantially equal to the width of the inner circumferential surface 14, and is formed with an elongated hole 24 extending along the circumferential direction.

Then, on this auxiliary plate 22, a pair of protrusions 18,
20 is supported.

One protrusion 18 is fixed on the top of the auxiliary plate 22, and the other protrusion 20 is supported so as to be movable on the auxiliary plate.

That is, the protrusion 20 includes a pin 26 that is loosely inserted into the elongated hole 24 and a stopper 28 that prevents the pin from coming off, and can slide in the circumferential direction along the elongated hole.

The protrusion 20 is located at the right end of the elongated hole 24 on the generatrix 30 on which the protrusion 18 is located, and is located on the other generatrix 32 at the left end of the elongate hole.

Note that the generatrix mentioned here refers to a line on the ring member 12 that is parallel to the central axis of the ring member.

By moving the protrusion 20 between the generatrix lines 30.32, the relative positional relationship of the protrusion 18.20 along the circumferential direction can be changed.

When the relative positional relationship between the protrusions 1B and 20 changes, the effective area of the circular hole 16 changes.

As shown in FIG. 5, the effective area of the circular hole 16 is
．． It is defined by the surface area of a circle 34 shown by a dashed-dotted line that is in contact with each of the extending ends of 20 and the inner circumferential surface 12.

The surface area of this circle 34 is defined as being largest when the protrusion 20 and protrusion 18 are located on the same generatrix line, that is, when the protrusion 20 is positioned on the generatrix line 30, and smallest when the protrusion 20 is positioned on the generatrix line 32. be done.

As the protrusion 20 moves between the generatrix lines 30 and 32, the surface area of the circle 34, that is, the effective area of the circular hole 16 changes.

When wearing the ring 10 configured as described above on a finger, first move the protrusion 20 onto the generatrix 30 as shown in FIG.
The ring member 12 is inserted into the finger with the effective area of the circular hole 16 set to the maximum.

At this time, since the effective area of the circular hole 16 is set to the maximum, the ring 10 can be inserted smoothly without getting caught in the joint of the finger.

Next, the ring member 12 is rotated to the right, for example in FIG. 2, with the projections 18.degree. 20 in contact with the fingers.

Alternatively, for example, by inserting a thin pin from the outside, the protrusion 20
Press to the left.

As a result, the protrusion 20 moves along the elongated hole 24 in the direction of the generatrix 32 and separates from the protrusion 18.

Therefore, the effective area of the circular hole 16 is reduced, the ring 10 fits the finger, and the joints prevent it from coming off.

When removing the ring 10 from the finger as described above, return the protrusion 20 to the generatrix 30 by performing the operation opposite to that when inserting it.
Set effective area to maximum.

By removing the ring 10 in this state, it can be easily removed without getting caught in the joint.

In the ring of the above embodiment, the protrusion 18 was fixed on the auxiliary plate 22, but as shown in FIG.
Another elongated hole 36 may be formed parallel to the elongated hole 4, and the protrusion 18 may slide along this elongated hole.

In this case, there is an advantage that the point where the protrusions 1B and 20 are located on the same generatrix can be freely set between the right end and the left end of the elongated hole.

Further, a pin 19 may be provided on one or both of the protrusions 18 and 20 so that the protrusions can be moved more easily.

Further, as shown in FIG. 7, an eject passage 38 may be formed in the elongated hole 24 so that the protrusion 20 can be removed from the elongated hole.

In this case, by replacing the protrusion 20 with another protrusion of a different size, the effective area of the circular hole can be varied over a wider range.

Further, in the embodiment described above, the protrusions 18 and 20 are located on the circumferential surface 1 of each other.
Although the protrusions are spaced apart from each other in the width direction of the protrusions 4, the protrusions may be disposed on the same circumference as shown in FIGS. 8 and 9.

In this case, in the illustrated state in which the respective protrusions are located on the same generatrix, the protrusions 4 fixed to the auxiliary plate 22
0 is housed below the protrusion 42 that is slidable along the elongated hole 24.

The above-mentioned embodiments are for illustrating the present invention and are not intended to limit the invention in any way, and all modifications and modifications within the technical scope of the present invention are also included in the present invention. Needless to say.

For example, in each of the above embodiments, the protrusion is provided on the auxiliary plate, but it may be provided directly on the ring member.

In this case, it is desirable that the stopper exposed on the outer peripheral surface of the ring member has a design that does not impair the decorativeness of the ring.

Further, in this case, since the external stopper of the ring can be moved, the protrusion can be easily moved.

Further, in the above embodiment, the number of protrusions is two, but the number of protrusions is not limited to two and may be increased as necessary.

Further, in the embodiment shown in FIG. 6, each elongated hole is formed at the same position in the circumferential direction, but one of the elongated holes may be formed offset in the circumferential direction.

In this case, the relative positions of the respective protrusions in the circumferential direction can be changed over a wider range.

However, it is necessary that each protrusion has a point located on the same generatrix.

Furthermore, the shape of the protrusion is not limited to the embodiments, as long as it can come into contact with an inserted finger.
