Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring which can cope with a difference in thickness depending on a part of a finger and does not shift at a mounting part.

[0002]

2. Description of the Related Art Conventionally, the size of a ring is determined by the size through which the thickest part of the finger passes, and the base of the finger, where the ring is actually worn, is the thickest part of the entire finger. If there is no problem, for example, if the joint is thicker than the mounting part, the size of the ring is determined by the size that passes through the joint, so the ring that passed through the joint is the mounting part of the base of the finger When the ring moved, the inner diameter of the ring was larger than the thickness of the wearing part, and the ring had rotated around the finger.

[0003] In particular, in the case of a ring in which a decoration such as a jewel is arranged at the center, when the ring rotates around the finger, the position of the decoration is shifted from the center of the finger. It was noticeable that the ring was not attached to the fixed place compared to the ring. In addition, the ornament sometimes touched the next finger, causing pain.

Therefore, a free-size ring having an adjusting function corresponding to the thickness of a finger has been devised. As disclosed in Japanese Utility Model Registration No. 3006203, a decoration base 200 for attaching jewelry or the like is provided. In the existing ring L ′ to be inserted, a protrusion or hole 3 is formed on the inner peripheral surface of the annular portion 100 into which the finger is inserted.
A ring stopper formed in an arc shape conforming to the inner peripheral surface provided with 00
There is one in which 400 is brazed 500 to the projection or hole 300 with one end thereof floating above the inner peripheral surface (FIG. 9).

The ring stopper 400 is made of an elastic material.
When the ring L 'to which the ring stopper 400 is attached is attached, the ring stopper 400 expands and contracts according to the thickness of the finger and tightens the finger, so that the ring L' does not shift.

[0006]

However, in the above ring stopper, a projection or a hole is provided on the inner peripheral surface of an existing ring, and the ring body itself must be processed in order to be brazed to that portion. If the ring body to be processed is a special memorial ring such as an engagement ring or a wedding ring, the memorial ring is subjected to processing such as brazing to change the prototype of the ring. That was a reluctance for the owner of the ring.

In addition, since the above-mentioned ring stopper prevents the slippage of the ring by tightening the finger, if the ring to which the ring stopper is attached is worn for a long time, the finger is pressed by the ring stopper and the wearing part is congested. There was a risk of doing it.

[0008]

Therefore, in order to solve the above-mentioned problems, according to the present invention, a plurality of convex portions protruding inward of the annular portion are provided on the inner peripheral surface of the annular portion for inserting a finger. The present invention provides a ring provided with a ring.

The present invention also has the following features. (1) A plurality of protrusions are provided on both front and rear edges of the inner peripheral surface of the annular portion. (2) The convex portion is provided on one half of one side of the annular portion. (3) The plurality of convex portions are formed in a smooth waveform. (4) The convex portions provided on the front and rear end edges of the annular portion are alternately arranged in the circumferential direction. (5) A decoration stand locking part is provided on one side half part of the annular part, and when combined with an existing ring having a decoration base part for attaching a jewel or the like, the decoration table locking part is the same with the decoration base locking part. Can be locked. (6) At least one side half of the annular portion is provided with a slit along the circumference so that the annular portion of the existing ring can be inserted and fitted from the slit, and the slits on the opposite inner edges of the slit are provided. A part of the width has been widened to serve as a decoration stand locking part. (7) At least one half of the annular portion is provided with a slit along the circumference so that the annular portion of the existing ring can be inserted and fitted from the slit, and a cut formed substantially at the center of the slit. The detached part was used as a decoration stand locking part.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION When deciding the size of a ring, in the case of a person whose joint is thicker than the base of the finger, which is the actual mounting site of the ring, the size of the ring should be large enough to pass through the joint. If you choose, the ring will loosen at the wearing site.

[0011] A ring according to the present invention solves the above problem, and has a plurality of convex portions protruding inward of the annular portion on the inner peripheral surface of the annular portion into which the finger is inserted. Therefore, when the same ring is worn on the finger, when the ring passes through the joint, the tissue with a high degree of freedom of deformation, such as skin and flesh of the finger, is released into the gap between the convex portions, and the finger is attached to the base of the finger. When the finger is located, the finger can be pressed by the convex portion, and even if the joint is thicker than the base of the finger, the ring can be prevented from shifting at the attachment site.

Moreover, the convex portion for pressing the finger is projected in accordance with the thickness of the base of the finger, which is the mounting portion of the ring, so that the finger is not congested by the pressing by the convex portion.

The plurality of projections may be provided only on the front and rear edges of the inner peripheral surface of the annular portion. In this case, the space between the projection along the front edge and the projection along the rear edge is also provided. Occurs,
It is possible to increase the space where the skin and the meat of the finger can escape. In addition, the inner peripheral surface of the annular portion may be depressed to further increase the space for allowing skin, meat, and the like to escape.

Further, in the finger, there are many tissues having a high degree of freedom of deformation, such as skin and flesh, on the abdomen side than the back side of the finger. Therefore, the convex portion is provided only on one half of the inner circumference of the annular portion. By attaching the ring so that the side provided with the convex portion is located on the ventral side of the finger, the skin, meat, and the like can be efficiently released.

The convex portion is preferably formed in a smooth waveform. By adopting such a shape, it is possible to prevent the convex portion from digging into the finger and congesting the finger when the ring is worn. The wearing feeling can be improved.

Further, if the convex portions provided on the front and rear end edges of the annular portion are alternately arranged in the circumferential direction, the convex portions serve as male screws, so that the ring can be inserted smoothly.

The ring according to the present invention can be worn not only alone but also in combination with an existing ring. That is, in preparation for the case where the existing ring includes a decoration base for attaching a jewel or the like, a decoration base locking part capable of locking the decoration is provided on one side half of the annular part. The ring according to the present invention can be combined with the existing ring by locking the ring base of the existing ring with the ring anchor.

When an existing ring is combined with the ring according to the present invention, the ring according to the present invention is configured so as not to shift at the mounting portion, and therefore the existing ring locked to the same ring is also placed at the mounting position. It can be prevented from shifting.

Therefore, it is possible to prevent the existing ring itself from being displaced without applying any processing to prevent the displacement of the existing ring itself. In particular, the existing ring can be used as an engagement ring or a wedding ring. In the case of a special memorial ring, it is very effective to prevent the ring from slipping without changing the memorial ring itself.

At least one half of the annular portion is provided with a slit along the circumference so that the annular portion of the existing ring can be inserted and fitted from the slit, and the slit is formed on the opposite inner side of the slit. A part of the edge can be widened to serve as a decoration stand locking portion. In this case, since the ring portion of the existing ring is completely housed in the ring portion of the ring according to the present invention,
The displacement of the existing ring at the mounting position can be reliably prevented.

As described above, instead of widening a part of the inner side edge of the slit facing the slit to serve as a decoration stand locking portion, a cutout portion is formed substantially at the center of the slit, and the cutout portion is formed. It can also be a decoration stand locking portion, in this case, the annular portion of the existing ring is completely housed in the annular portion of the ring according to the present invention,
Not only is the gap at the mounting position of the existing ring reliably prevented, but also the decoration stand locking part is a cut-out part at the center of the slit,
The decoration base of the existing ring will be housed in such a separation part, and even if the size of the decoration base varies in size,
The decoration stand locking part can lock the decoration base part corresponding to the size.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A ring according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, the shapes of the human fingers 60, 60 ', 60''can be roughly divided into three types. That is, a straight type in which the tip portion of the finger 60 ′ to the root portion 61 has almost the same thickness (FIG. 1A), and a joint thick type in which the second joint portion 62 is thicker than the root portion 61 of the finger 60. (FIG. 1 (b)), a lower swelling type (FIG. 1 (c)) which becomes thicker as it approaches the base 61 of the finger 60 ''.

The attachment site 61 of the ring L 'is usually the fingers 60, 60', 6
It is the base part 61 of 0 '', but the size of the ring L 'is
Is determined so that the maximum diameter portion can pass through. Here, in the straight type and the downward swelling type, the mounting portion 61 of the ring L 'and the maximum diameter portion of the fingers 60', 60 '' coincide with each other,
Since both are the base portions 61 of the fingers 60 ′ and 60 ″, the ring does not shift at the mounting site 61 even with the conventional ring L ′.

However, in the articulated type, the maximum diameter portion of the finger 60 is the second joint portion 62 and the maximum diameter portion is the mounting portion 61.
When the size of the ring L ′ is determined not to match the base portion 61 of the finger 60 and to be large enough to pass through the second joint portion 62, the diameter of the ring L ′ is too large at the mounting portion 61. And rotate around the finger 60.

In view of the above, the ring L1 according to the present invention has a joint-thick type finger in consideration of the difference in thickness depending on the part of the finger 60.
Even if it is 60, it is configured not to shift at the mounting portion 61, and it can be mounted without shifting to any type of fingers 60, 60 ', 60''.

A plurality of convex portions 2 protruding inward of the annular portion 1. In addition, the convex part 2 can also be provided in the whole front-back width direction of the inner peripheral surface of the annular part 1. The finger that is the attachment site 61 of the ring L1
Since the base portion 61 of the finger 60 is thinner than the second joint portion 62, when the ring L1 is located at the base portion 61 of the finger 60, the finger 2 is pressed by the convex portion 2 so that the ring L1 does not shift.

The convex portion 2 for pressing the finger 60 is made to protrude in accordance with the thickness of the base portion 61 of the finger 60, which is the mounting portion 61, so that the pressing by the convex portion 2 prevents the finger 60 from congestion. I have. Therefore, when the ring L1 according to the present invention is located at the base portion 61 of the finger 60, which is the mounting portion 61, a space is formed in the gap between the convex portions 2 and therefore, when the ring L1 is mounted. The portion 61 can be prevented from getting stuffy.

The space between the convex portions 2 is a space into which a tissue 65 having a high degree of freedom in deformation such as skin and flesh of the finger 60 escapes when the ring L1 passes through the second joint portion 62. Becomes That is, as described above, the inner periphery of the annular portion 1 formed to have a size that allows the second joint portion 62 to pass therethrough
Although the size of the annular portion 1 is reduced, the tissue 65 having a high degree of freedom of deformation, such as skin and meat, is released into the gap between the convex portions 2 and the inner peripheral surface of the annular portion 1. Even if the protrusion 2 is provided, the ring can be passed through the second joint portion 62.

Since the finger 60 has more tissues 65 having a higher degree of freedom in deformation on the abdomen 64 side than on the instep 63 side, the convex portion 2 is provided only on one half of the inner circumferential circle of the annular portion 1. When the ring L1 is worn, the finger 65 is worn so that the side on which the convex portion 2 is provided is located on the belly 64 side of the finger 60, and the tissue 65 having a high degree of freedom of deformation of the finger 60 is moved to the convex portion 2 and the convex portion 2. Efficiently escape between.

Here, the diameter of the circle a is determined by the length of the longest part of the bone 66 having a low degree of freedom of deformation, that is, the width of the finger 60.
The cross-sectional area of 62 is smaller, and in the description of FIG.
In order for the joint portion 62 to pass through the annular portion 1, the finger 60
The area (c) in which the finger 60 can be inserted should be larger than the area of the circle a (FIG. 3 (b)). The cross-sectional area should be larger than the cross-sectional area 62 (FIGS. 3 (c) and 3 (d)).

Also, like the circle a, the diameter of the circle b is determined by the width of the longest part of the bone 66 having a low degree of freedom of deformation, that is, the width of the base 61 of the finger 60.
The convex portion 2 is projected so as to circumscribe a circle b formed of a perfect circle, which is assumed to be the base portion 61 of the finger 60, but the actual cross-sectional area of the base portion 61 of the finger 60 is smaller than the circle b.

Therefore, the convex portion 2 is made to protrude according to the cross-sectional shape of the finger 60 so as to be inscribed in the inner circumferential circle of the annular portion 1, and
By making the circle circumscribing the convex portion 2 provided on the inner peripheral surface of the annular portion 1 to be an ellipse, the pressing of the finger 60 by the convex portion 2 becomes more reliable, and the fitting feeling of the ring L1 in the mounting portion 61 is improved. improves.

According to the first aspect of the present invention, a plurality of protrusions projecting inward from the annular portion are provided on the inner peripheral surface of the annular portion into which the finger is inserted. When the same ring is worn on a finger, the skin and flesh of the finger are released into the gap between the convex portions when the ring passes through the joint, and the finger is pressed by the convex portion when the ring is located at the base of the finger, which is the mounting site. Even if the joint is thicker than the base of the finger, the ring can be prevented from shifting at the mounting site.

According to the second aspect of the present invention, since a plurality of protrusions are provided on both front and rear edges of the inner peripheral surface of the annular portion, a space is also created between the front and rear protrusions. It is possible to increase the space for allowing skin and meat to escape.

According to the third aspect of the present invention, the convex portion is provided on one side half of the annular portion, and the ring is mounted such that the side provided with the convex portion is located on the ventral side of the finger. In addition, tissues having a high degree of freedom in deformation, such as skin and meat, which are present more on the ventral side than on the back side of the finger, can be efficiently released into the space between the convex portions.

According to the fourth aspect of the present invention, when the plurality of convex portions are formed into a smooth waveform, it is possible to prevent the convex portions from biting into the finger when the ring is worn,
The wearing feeling can be improved.

According to the fifth aspect of the present invention, the convex portions provided on the front and rear end edges of the annular portion are alternately arranged in the circumferential direction. It can be inserted smoothly.

According to the sixth aspect of the present invention, when the decoration base locking part is provided on one side half of the annular part, when combined with an existing ring having a decoration base part for attaching jewelry or the like, In the same decoration base locking part, by enabling the decoration base part to be locked, when an existing ring is combined with the ring according to the present invention, the ring according to the present invention is configured so as not to shift at the mounting part. Therefore, the existing ring locked to the same ring can be prevented from shifting at the mounting position. As described above, it is possible to prevent the existing ring itself from being displaced without applying a process for preventing the existing ring itself from being displaced, particularly when the existing ring is used as an engagement ring or a wedding ring. It is a special memorial ring, and it is very effective when you do not want to change the prototype of the memorial ring.

According to the seventh aspect of the present invention, at least one half of the annular portion is provided with a slit along the circumference, and the annular portion of the existing ring can be inserted and fitted from the slit. In addition, by expanding a part of the opposed inner edge of the slit to a decoration stand locking portion, when the ring according to the present invention and the existing ring are combined, the annular portion of the existing ring is Since the ring according to the present invention is completely accommodated in the annular portion of the ring, it is possible to reliably prevent the existing ring from shifting at the mounting position.

According to the present invention, a slit is provided along at least one half of the annular portion along the circumference, and the annular portion of the existing ring can be inserted and fitted from the slit. And, by combining the ring according to the present invention with an existing ring by using a cut-off portion formed substantially at the center of the slit as a decoration stand locking portion, the annular portion of the existing ring is used in the present invention. Not only is the ring completely housed in the annular portion of the ring, and the displacement of the existing ring at the mounting position is reliably prevented, but also because the decoration stand locking portion is a portion where the annular portion is cut off, the decoration of the existing ring The pedestal is to be accommodated in the separation portion, and even if the size of the pedestal is large or small, the pedestal lock is engaged with the pedestal corresponding to the size. Can be stopped.
