JP6401259B2 - Decorative body pedestal for removable decorative bodies, products and methods comprising such pedestals - Google Patents

Description

  The present invention relates to jewelry and in particular to jewelry with a decorative body that can be removed and reassembled by a user.

  In the art, many different precious stone pedestals with a wide variety of designs are known. These pedestals are used to contain and secure gemstones or similar ornaments in jewelry products such as rings, brooches, bracelets, necklaces or tiaras. The pedestal is typically made up of somewhat intricately shaped retaining parts that require the substantial skill of a jeweler, and this makes installation and replacement of stones or other ornaments complex and time consuming It is a costly work.

  Conventionally, a pedestal includes a base with a number of upwardly extending claws, with the ends of the nails folded over on a stone or decorative body to contain it and hold it securely in place. The number of nails and their distribution depend on the size and shape of the stone.

  Such decorative pedestals and similar commonly used pedestals typically require skill and specialized equipment to properly assemble the decorative body into a jewelry product. Therefore, it is difficult to remove and replace precious stones and decorative bodies from such a pedestal, and the jewelry including such a pedestal is fixed. In addition, for design and aesthetic reasons, it may not be desirable to have a visible portion on the nail or similar structure that folds over the stone and partially covers it.

  It is known in the industry to assemble gemstones or other decorative bodies in a precious stone pedestal that gives the sensation that the precious stone is stationary in the air on a titanium jewelry product. The precious stone pedestal includes two ornamental holders resembling jaws connected through a base structure and facing each other. On each of the facing surfaces inside the two decorative body holders, a notch or groove designed to grip the gem or decorative body is arranged. If a suitably sized ornament must be assembled, the ornamental jaws can be forced apart or separated by lever action to slide the edges of the ornament into the grooves, at which point the jaws are released and elastic Therefore, it is necessary to return so that the decorative body can be pressed. The decorative body is such that the decorative body is held in place by the groove and by a force having an inward direction exerted by the decorative body holder as the decorative body holder attempts to return to its original position. The fixture is made with slightly oversized dimensions. This configuration works in a precious stone pedestal made of titanium because it is a material that can store tension generated when the decorative body holder is forcibly opened and thus elastically deformed. This also works for gold and silver alloys and other metals with sufficient elasticity and strength. This configuration requires special tools for precious stone assembly, and the use of this configuration is limited to materials with high tension storage capabilities.

  Examples of different interchangeable precious stone pedestals that currently exist in the field of jewelry can be found in the following publications:

  Patent document 1 to the same inventor as the present invention, in one embodiment, can be slid on two grooved decorative body holders in one direction and can be combined with the decorative body holder when twisted by 90 °. A removable pedestal pedestal pedestal is described that utilizes an oval clamp ring that can be pressed to hold and hold the precious stone within the pedestal.

  U.S. Patent No. 6,057,032 describes a second removable decorative ring that is intended to be coupled and placed around another finger-worn ring to enhance its appearance. The device consists of an O-shaped jacket that engages around the center stone of the finger mounting ring by being hinged open at one point and closed with a clasp on the other side. The jacket firmly restrains the central stone accessory and stays in place with pressure. The purpose of the second ring is to augment the central stoned accessory, which itself does not allow for the replacement of the central precious stone.

  U.S. Patent No. 6,057,031 describes a compatible jewel pedestal that includes two thread-like circles that are firmly fixed in a jewelery product and that are inclined to face each other at a certain angle and that contact each other at one position. The diameter of the circle and its intermediate distance are smaller than the diameter of the gemstone to be assembled. The removal and retention of the jewel is made possible by the ability of the circle to spread and separate and return by elasticity to surround and press the jewel.

  Patent Document 4 describes a replaceable precious stone pedestal in which a precious stone is held in place by a casing and a hinged bottom cover.

  U.S. Patent No. 6,099,056 describes a ring in which a stone is held between two wings, where the wings include ribs and notches for gripping the stone. In order to support the stone from below and prevent the stone from shaking up and down, a support is also placed at the base of the stone using a lower notch.

  U.S. Patent No. 6,057,056 describes a stone accessory with a pedestal where a stone is held between two wings and a hinged support and the stone is supported from below.

  Other examples of related technology can be found in Patent Document 7, Patent Document 8, Patent Document 9, Patent Document 10 and Patent Document 11.

  Primarily allows easy and reliable removal and replacement of stones or other decorations on jewelry products without the need for any tools or special skills, and a wider range of materials such as softer gold or silver can be used There is a demand for jewelry pedestals to do so.

  For example, in addition to the stone or decoration described above, there is also a need for a jewelry pedestal that can completely change the design of the jewelery by changing the parts of the pedestal that surrounds the central part.

  The expressions “clamp ring” and “clamping ring” are used interchangeably herein. The expressions “decorative body holder” and “jaw” are used interchangeably herein.

  The pedestal according to the present invention may be used to secure a decorative body such as a jewel or other different decorative body. The decorative body may be selected from stones, watch dials, seals, pearls and metal parts or any combination thereof.

  The pedestal may be part of a jewelry or watch, which includes a ring, brooch, bracelet, necklace, earring, tiara, cufflink, bangle, tie pin, (collar badge) pin badge, (tuxedo) stud, forehead jewelry May be selected from charms, hand chains, and the like.

  It should be pointed out that jewels or other decorative bodies may have different shapes and sizes.

  The pedestal according to the invention comprises preferably two decorative body holders similar to claws or jaws connected through the base structure (pedestal) and facing each other. A jewel or a decorative body may be disposed between the decorative body holders. The stone or decorative body is firmly fixed in place using a clamping ring. The clamping ring is provided around the ornament holder, i.e., surrounds or surrounds the outside of the ornament holder. The inner dimension surface of the clamping ring may be in partial contact with the surface of the decorative body holder opposite to the surface of the decorative body holder facing each other. The mentioned surfaces may be referred to as facing surfaces and back surfaces, respectively. The decorative body holder may be gently pulled apart so that it is spaced enough to remove and replace the decorative body placed in between.

  The pinching ring enables the precious stone or the decorative body arranged between the opposing decorative body holders to be released in the releasing direction, and alternatively, the precious stone or the decorative body between the decorative body holders (jaws) is released. It has an inner dimension that allows insertion. The clamping ring is such that the clamping ring exerts a clamping force on the opposing decorative body holders in order to grip and securely fix the precious stone or decorative body placed between the decorative body holders in the clamping direction. Has inner dimensions. The clamping ring is in contact with the decorative body holder at one position, and this position may be any location along the decorative body holder, for example, the neck of the decorative body holder. The neck may include a groove or depression in the decorative body holder.

  In one embodiment, the clamping ring is adapted to be removed from the decoration, for example by sliding the ring over both opposing decorative body holders.

  In one embodiment, the pinching ring has a partial oval shape (oval shape) in its inner dimension.

  In one embodiment, the decorative body retainer may include a notch or groove designed on its inside surfaces facing each other designed to grip the jewel or decorative body when secured.

  In one embodiment, the decorative body holder may include a shelf or tray designed to hold and grip the jewel or decorative body when firmly secured on its inner surfaces facing each other. .

  A pair of decorative body holders is provided. The decorative body holder at least partially wraps the decorative body in the assembled base. The decorative body holder may be regarded as a clamping jaw and may or may not completely surround the precious stone or other decorative body. The ornament holder above the area in contact with the clamp ring in the direction towards the precious stone or ornament may have a different shape. Each decorative body holder may include a spacing or opening. The portion of the ornament holder that is provided with precious stones or other ornaments may be provided in a shape suitable for or adapted to the particular ornament to be secured. The internal space formed between the decorative body holders is intended to follow or reflect the shape of the decoration. The part of the decorative body provided with the decorative body may include an opening. Such an opening may exist up to the position of the clamp ring in the decorative body holder. Therefore, the decorative body holder does not necessarily have to be made of a single solid shape without any opening or interval.

  The decorative body base structure preferably has an at least partially flexible shape. This flexibility makes it easy to remove and reassemble the decorative body. The decorative body base may be at least partially in a circular shape. It may be a ring, an oval or a bent shape (eg an arc). In one embodiment, the decorative body base may include at least two circular ring-shaped bases. In this latter embodiment, the decorative base, for example a circular ring base forming a ring base, is separated from one another by at least one spacing. The circular ring-shaped bases are preferably positioned facing each other so that the decorative ring base can be placed, for example, on the wearer's finger. Preferably, the circular ring-shaped base has an equal shape. Thus, the decorative ring base may include at least one spacing that runs along the periphery and divides the decorative ring base into at least two sections. The spacing may be along at least a portion of the periphery of the decorative ring base.

  In the above-described spacing between the circular ring-shaped bases, additional rings or rings that engage within the spacing may be incorporated in order to modify the design of the decorative ring, for example the entire ring.

  The clamp ring may comprise at least two layers, or may consist of at least two layers. One layer is a top or bottom layer, preferably the top layer, and the second layer is a spring metal layer. Further, the clamp ring may include a third layer, a bottom layer. The layers of the clamp ring are positioned adjacent to each other, preferably on top of each other. If two layers are used, the upper layer is closest to the precious stone or decorative body and the spring metal layer is positioned below the upper layer. If three layers are used, the spring metal layer is sandwiched between the upper and lower layers. At least two layers are fixed to each other at a fixed point. These fixed points may be fixed points between layers, or may be holes in layers that are joined by a heel.

  The top layer and / or the bottom layer may include jewels and / or other decorations as a decorative part of the upper portion of the top layer that does not face the spring metal layer. A clamp ring with three layers is reversible in use. The three-layer clamp ring may be clamped in both directions around the ornament holder so that the upper or lower layer can be placed closest to the decoration. When the upper layer and the lower layer are of different designs, the design of the decorative body pedestal varies depending on which layer is closest to the assembled decorative body in the pedestal.

  The clamp ring may be provided in the opposing holding decorative body holder and may surround the decorative body holder. The clamp ring preferably has an at least partly elliptical interior. The dimensions are different across the oval ring. Cross the place where the ellipse is the widest (main axis), jewelry, precious stones between decorative body holders (jaws) that can be installed with grooves to clasp jewelry or decorative bodies Or a decorative body may be provided. At this time, the holding ring can be rotated around the decorative body holder in either the clockwise direction or the counterclockwise direction, where the oval shape of the holding ring exerts a force on the decorative body holder. In addition, these decorative body holders are brought close to each other, and as a result, a precious stone or a decorative body is firmly fixed between the decorative body holders. Here, one should notice when the oval clamping ring comes to its narrowest internal axis, ie the smallest diameter, which is the preferred fixed spot. However, the precious stone or the decorative body between the decorative body holders may be held at a predetermined position at another position between the widest direction and the narrowest direction of the holding ring. The holding ring is bent and uses a spring metal layer of the holding ring to apply a force necessary to keep the precious stone or the decorative body in a predetermined position between the decorative body holders on the decorative body holder. Kept in place.

  In order for the restraining and locking mechanism to function as desired, the clamping ring preferably has an essentially oval shape. However, a ring is not necessarily a perfect ellipse. The minimum circumferential diameter of the clamp ring is where the clamping ring is in contact with the part of the decorative body holder and forces the decorative body holder to move closer to each other so that the decorative body is securely fastened between them. is there.

  In one embodiment, the minimum inner diameter of the clamp ring is located 90 ° from the maximum inner diameter of the clamp ring. In such an embodiment, the releasing direction of the clamp ring (the releasing position at the maximum inner diameter) is 90 ° from the clamping direction of the clamp ring (the holding position at the minimum inner diameter).

  From this minimum diameter, the inner diameter expands along its circumference until it reaches a maximum value for the clamp ring, as it does for an ellipse, and then decreases towards the corresponding minimum diameter.

  The clamping ring is moved when its shape, preferably at least partially oval, is moved away from each other as much as possible, i.e. when the clamping ring is within its widest internal axis, The holding ring may have a dimension that allows the parts to be separated from each other by removing the clamping ring from its position along the decorative body holder. At this time, the holding ring is removed from the decorative body holder. In such an embodiment, the decoration should not be too large, since the size of the decoration removes the clamp ring from the distance between the decoration holders and thus the position around the decoration holder. This is because it affects the inner diameter of the clamp ring when it must be. In this embodiment, the dimensions of the precious stones or other ornaments intended to be between the ornament holders are preferably smaller than or similar to the inner diameter of the clamping ring. The inner diameter may be selected in any direction.

  Larger precious stones or ornaments may also be firmly fixed using the same techniques as described above, in which case the diameter of the clamping ring in any direction is the size of the ornament holder around the precious stones or ornaments. Smaller than the diameter of this precious stone or ornament combined with its size. In this embodiment, the holding ring surrounds the decorative body holder, and the holding ring may not be removed from the decorative body holder by sliding the holding ring along the decorative body holder. However, in this embodiment as well, the clamping ring firmly secures the precious stone or ornament between the ornament holders at its smallest internal axis and releases the precious stone or ornament at its widest internal axis. Thus, for example, precious stones and / or decorative bodies may be replaced.

  The spring metal layer has an inner circumference similar to at least one other layer. The at least one other layer has at least a partial oval inner circumference.

  The spring metal layer may be made of at least one part, for example one part or two parts, including a fixing point for securing it / at least one other layer of the clamp ring. ing. The fixing point may be a welding point or a hole into which a rivet or pin is inserted.

  The spring metal layer may have one opening in its ring shape, thus giving a more horseshoe-like shape. The spring metal layer includes at least one anchoring point, such as a hole, for securing and anchoring it to at least one other layer of the clamp ring. The spring metal layer may include two holes for securing it to at least one other layer of the clamp ring, for example both the upper and lower layers of the clamp ring. This type of spring metal layer may bend outward and form a gap when the entire composite clamp ring is rotated between the release and clamping positions. The spring metal layer may be composed of flat portions.

  The spring metal layer may be composed of two separate parts, for example two halves. The separate parts are arc-shaped. The arc includes a fixing point, such as a hole, to securely fix and fix each arc to at least one other layer of the clamp ring. The arc may include two fixation points, each for securing each arc to at least one other layer of the clamp ring, eg, both the upper and lower layers of the clamp ring. The spring metal layer may be made of a flat spring metal.

  While at least one end of the spring metal layer is rapidly held through the fixing point, the other end (s) can be pushed outward and bent, this end being a compound clamp A gap may be formed when the entire ring is rotated between the release position and the clamping position. As the clamp ring is rotated toward its constraining clamping position, the inner surface of the clamp ring presses the decorative body retainer on its back rather than the facing surfaces with the decorative body in between. The clamp ring may wrap the decorative body holder at the neck portion of the decorative body holder.

  Protrusions may be provided on the clamping ring, preferably on the spring metal layer, so that a secure fastening means for precious stones or other decorative bodies is obtained between the decorative body holders. The protrusion may be incorporated into the inner dimension of the clamp ring. These protrusions are preferably arranged on the narrowest, ie the smallest internal axis, of the spring metal layer of the clamp ring. These protrusions may further increase the clamping force at the time of rotation from the release position to the restraining clamping position. These protrusions of the spring metal layer of the clamp ring may be adapted to be received by recesses on the outer side of the ornament holder / jaw, i.e. opposite to the sides facing each other, for example by dimple recesses. These depressions may be on the neck portion of the decorative body holder. The neck portion of the decorative body holder may be present at any position along the decorative body holder. Thus, the recess is provided on the decorative body holder at a corresponding position so that the aforementioned projection of the clamp ring can be accommodated. When the precious stone or the decorative body is firmly fixed between the decorative body holders, the clamp ring is rotated from the circumference of the widest internal axis toward the minimum internal axis. Once the clamp ring protrusion is introduced into the jaw recess, a tight and repeatable constraint of jewelry and decoration is obtained. This restraint mechanism provides a clear restraint function for jewelry users.

  Recesses and protrusions are not necessary to keep the precious stones or ornaments in place, but are more reliable for the user to place the precious stones or ornaments in place with the best possible restraint. And reducing the risk of excessive loosening of precious stones or decorative bodies. The depressions and protrusions likewise make it possible to obtain the best possible design of the assembled jewelry, since the symmetry of the intended design of the jewelry is kept constant.

  In another embodiment, additional dimples may be created in the decorative body holder, for example for aesthetic reasons.

  In one embodiment of the present invention, the clamp ring has a partially oval shape. The oval shape is around the smallest diameter of the inner circumference of the clamp ring. The circle has an angle of 360 °. An ellipse (or an ellipse) is a kind of elongated circle and also has an angle of 360 °. This means that the narrowest position in the smallest diameter of the inner circumference of the clamp ring can be at 0 and 180 °. As an example, the elliptical shape of the inner circumference of the clamp ring is approximately 60 ° (eg 50 °, 40 °, 30 ° on both sides of the narrowest position (at the smallest inner diameter) of the clamp ring, ie where the diameter is smallest. ). If approximately 60 ° has an oval shape on either side of the narrowest position of the clamp ring, approximately 240 ° of the entire clamp ring has an oval shape. The remaining portion (remaining 120 °) has an arbitrary shape, for example, outward from the center, curved shape, pointed shape, blunt end shape, partial circular shape, linear shape, etc., and is partially elliptical The clamping ring may be closed.

  The holes used to fasten and secure the spring metal layer to at least one other layer of the clamp ring are provided adjacent to each other in one half of the clamping ring, i.e. within 180 ° from each other. Good. In another option, they are provided on substantially opposite sides, i.e. in the section of the spring metal layer as well as on the opposite side of the final clamping ring.

  The present invention provides a modular clamping ring. It is built in multiple layers, but in an inconspicuous and invisible way, giving the viewer the impression of a solid ring.

  Figures 1, 2 and 3 show one assembled ring according to the invention comprising a ring base 1 with two jaws 2a and 2b holding a precious stone 3 between two jaws 2a and 2b. . The jaws are pressed together by three layers (4a, 4c and 4b) of the clamp ring 4 in the manner described below. Throughout the drawings, the same components or components having the same function are denoted by the same reference numerals.

  FIG. 4 shows a ring without precious stones and a clamp ring. In this view, the ring base 1 extending through the neck 10 to the two clamping jaws 2a and 2b that are spaced apart from each other can be seen more clearly. Inside each jaw is a groove 7a, 7b (as shown in FIGS. 1-3) for holding the edge of the precious stone. On the outside in the neck portion of each jaw, dimple-like depressions 5a, 5b are provided, and the protrusions of the clamp ring are snap-engaged in the dimple-like depressions, as will be described in more detail below. Pressing together will hold the precious stone firmly in place.

  Figures 5 (a) and 5 (b) show two different versions of the clamp ring used in the decorative pedestal according to the present invention, one jeweled and the other without decoration. ing. Each ring in this embodiment has an oval interior. The ring is provided with protrusions 6a and 6b across the place where the ellipse is narrowest, i.e. where it has the smallest diameter (short axis).

  The configuration of the clamp ring can be easily seen in FIGS. 6 (a) and 6 (b). Each clamp ring is composed of three layers (spring metal layer 4c sandwiched between 4a and 4b), and has protrusions 6a and 6b on the intermediate spring metal layer 4c.

FIG. 7 shows in more detail the configuration of the intermediate spring metal layer 4c sandwiched between the top and bottom layers 4a and 4b to make up the clamp ring 4. Two separate halves 4c ₁ and 4c ₂ constitute the intermediate layer 4c. The separate halves 4c ₁ and 4c ₂ are flat spring metal arcs. Each spring metal arc 4c ₁ and 4c ₂ has two fixing points, or holes 8, to securely fix and fix each arc to the upper and lower layers 4a and 4b of the clamp ring. One end of each flat spring metal arc 4c ₁ and 4c ₂ is rapidly held through the hole 8, while the other end has a dimple-like depression aligned with the main axis (the widest distance). When the entire composite clamp ring is rotated from the released position to the clamping position, it can be pushed and bent outwardly between the upper and lower layers 4a and 4b. As the clamp ring is rotated toward its constraining clamping position, which in this case is clockwise, the protrusions 6a and 6b press against the neck portion 10 of the jaw, and the ends of the spring metal arcs 4c ₁ and 4c ₂ Bend the part outward and beyond the normal circumference of the clamp ring. When the protrusions 6a and 6b reach alignment with the dimple-like depression, the protrusion of the spring metal arc snaps into the dimple-like depression in the neck so that the holding ring comes out of its holding position. Prevent spinning.

FIG. 8 shows two spring metal arcs 4c ₁ and 4c ₂ sandwiched between the upper and lower layers 4a and 4b of the clamp ring, where the entire clamp ring package is a plate metal arc 4c _1. And four pins 9 extending through the holes 8 in 4c ₂ .

  A precious stone or other ornament is assembled in place by pulling the jaws 2a and 2b apart and engaging the edges of the precious stone into the grooves 7a and 7b. The inherent pressure of the ring 1 preliminarily holds the precious stone 3 in place. The clamp ring has already been slipped over the jaws at that position where the ellipsoidal main axis is aligned with the jaws.

  The exemplary embodiment described here is provided with grooves 7a and 7b for gripping the decorative body, but is dimensioned to fit snugly the rounded end or side of the decoration, for example. It is also contemplated that restraint engagements other than grooves, such as shelves and saddles for precious stones that have been recessed or crescent cut, and that the decorative body can be retained in the jaws, each of these possibilities. , As defined in the main claim, within the scope of the definition of “gripping the decoration”.

The clamp ring 4 is in a position where its main axis is aligned with the dimple-like depressions 5a and 5b. At this time, the clamp ring is rotated in the clockwise direction, and the ends of the protrusions 6a and 6b and the spring metal arcs 4c ₁ and 4c ₂ as the neck portions of the jaws 2a and 2b come into contact with the narrowing section of the clamp ring 4. Is forced outward and the jaws holding the precious stone are pressed together more tightly. Eventually, the protrusions 6a and 6b snap into the dimple depressions 5a and 5b in the restrained position. The clamp ring 4 is firmly held in this position with the jaws pressed together holding the precious stone, and there is no possibility of accidental escape from that position and rotation. To release the precious stone and replace it with another one, rotate the clamp ring 4 counterclockwise to first force the protrusions out of the dimple-like depressions in which they are contained, and then The clamp ring 4 is rotated by 90 ° until the inner ellipse main axis of the clamp ring 4 is aligned with the jaw. At this time, the jaws 2a and 2b of the ring 1 can be gently pulled apart enough to remove and replace the precious stones. The clamp ring can be removed and replaced only after removing the precious stone, for example.

According to one advantageous embodiment of the invention, the spring metal arcs 4c ₁ and 4c ₂ are pushed slightly outwards during the rotation of the clamp ring, so that a little around the clamp ring defined by the layers 4a and 4b. Are dimensioned and assembled in such a way that they can project outward. When the protrusions 6a and 6b are retracted in the dimple-like depressions 5a and 5b, the spring metal arc has already returned to a position where the outer surface is exactly aligned with the outer periphery of the outer layer of the clamp ring, thus Shows an attractive outer surface.

The arrangement of the present invention provides a more secure fixation of precious stones in jewelry products than previously possible in jewelry with conventional user-compatible stones or other ornaments. Once the protrusions 6a and 6b on the spring metal arcs 4c ₁ and 4c ₂ snap into place, the clamp ring is securely held in the stone restraint position. To release the stone again, an additional force is required to force the protrusion out of the dimple depressions 5a and 5b by rotating the clamp ring counterclockwise. Similarly, in this new configuration, the intermediate layer 4c of the clamp ring 4 can be made of industrial spring steel, while the outer visible layers 4a and 4b can be made of a softer noble metal such as gold or silver. Alternatively, the intermediate layer can be made of a gold alloy, such as white gold or other metal having spring properties. The neck portion 10 of the jaws 2a and 2b, including the dimple depressions 5a and 5b that interact with the protrusions, is not visible when the stone is assembled and can be made of a harder metal or alloy as well. In this way it is possible to change the stone many times without damaging the ring part.

  A further advantageous embodiment is described in connection with FIG. 12, where the spring metal layer is unitary. A single body can be described as having two integrated arcs with an intermediate portion forming a symmetrical horseshoe shape. It will be appreciated that this embodiment can be implemented in other shapes as well, such as a perfect ellipse with a slight gap between the ends of the spring metal arc.

FIG. 12A shows the clamp ring of the present invention having a slightly different shape from the clamp ring 4 of the previous embodiment. In this case, it is three-layered as in the previous embodiment, but the spring metal intermediate layer 4f is not composed of two separate arcs each assembled at its end, rather The two spring arcs 4f ₁ and 4f ₂ form a symmetrical horseshoe-shaped spring plate 4f that is integral with each other via an intermediate fixing part 4f ₃ . As in the case of the clamp ring described above, the intermediate layer 4f is sandwiched between the two outer layers 4d and 4e, but in this embodiment, the lower layer 4e has the ends of the arcs 4f ₁ and 4f ₂ . A raised filler section 4e ₁ straddling the space between is provided, creating a tight clamping ring.

As in the case of the embodiment described above, the decoration is held between the jaws 2a and 2b of the decorative body base 1 (see FIG. 4). In this embodiment, the same decorative body base such as the ring of FIG. 4 is used. Figures 12 (b), (c) and (d) show the advantageous operation of the clamp ring. FIG. 12B shows only the two bottom layers 4e and 4f of the clamp ring 4f of the present embodiment, and more clearly shows the spring action of the clamp ring. As in the case of the above-described embodiment, the oval clamp ring allows the main axis of the oval inner dimension of the clamp ring to align with the jaw and slide over it before the precious stone is assembled. Can be slid over the jaws 2a and 2b (this step is not shown here in FIG. 12). A decoration such as a precious stone is then placed between the jaws with the stone edges in the grooves 7a, 7b and the clamp ring is rotated to the position shown in FIG. 12 (b). Here, only the necks 10 of the two jaws 2a and 2b are shown (see FIG. 4), the stone held between them is not shown. In this restrained position, the protrusions 6c and 6d have already snapped into the dimple depressions 5a and 5b in the neck 10 to firmly restrain the stone in place. In order to release the stone, in this embodiment it is possible to rotate the clamp ring in either direction. The rotation in the counterclockwise direction is shown in FIG. 12 (c), and the rotation in the clockwise direction is shown in FIG. 12 (d). When rotated in either direction, the protrusions 6c and 6d rise out of the dimple-like depressions 5a and 5b and escape, and each of the arcs 4f ₁ and 4f ₂ forming the integral horseshoe-shaped plate 4f portion Forced outwardly against the inherent spring force of, creates a gap 13 between the ends of the arcs 4f ₁ and 4f ₂ and pushes the arc slightly out of the normal circumference of the clamp ring. This embodiment has the advantage that it is symmetrical and receives a load symmetrically when the arc is bent outwards. As in the previously described embodiment, the sandwich is held together by four symmetrically assembled pins 91 and 92. In this case, the symmetrical shape with the arcs 4f ₁ and 4f ₂ in the integrated horseshoe 4f is such that each upper pin 91 simultaneously receives the force acting upward and the force acting downward due to the lever action, and thus the majority This means that the lifetime of the decoration can be extended significantly. Similarly, in this embodiment, precious stones can be released or restrained by rotation in either direction, eliminating the need for detailed and difficult-to-remember instructions for use.
