Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a stone holder for accessories, and particularly to a stone holder used for rings, pendant heads, etc.

<Prior Art> When using a stone as the head of a ring or pendant, it is necessary to fix the stone with metal such as gold, silver, or platinum and attach it to the ring or chain.

As a conventional example of this method of fixing, for example, a claw is formed on the bottom of the stone or a metal part serving as a frame, and after the stone is stored, the stone is fixed by caulking the claw.

There is also a type that consists of a bottom frame and a lid frame that can be opened and closed, and stones are stored between them and fixed by sandwiching them.

<Problems to be solved by the invention> However, such conventional stone holders have the following problems.

First of all, for those that are fixed with nails, each time you change the stone, you have to loosen the nail, replace the stone, and re-caulk, so it is not easy to change the stone.
There was also a limit to the number of times.

Next, in a case that consists of a bottom frame and a lid frame that can be opened and closed freely, it is easy to replace the stone, but if the size of the stone is different, for example, if you replace it with a stone smaller than the optimal size, the frame and the There will be a gap between the

In view of these conventional problems, it is an object of the present invention to provide a stone holder that allows easy stone replacement and does not create gaps even if the stones are of slightly different sizes.

<Means for Solving the Problems> For this reason, the present invention provides an accessory stone holder consisting of a bottom member and a substantially annular lid member that can be opened and closed, and stones are stored between the bottom member and the bottom member. In the tool, a C-shaped plate spring having a substantially cylindrical shape with an axis in the direction of pressing the stone and having slots substantially parallel to the axis is supported by the bottom member at a part of the circumference so that it can be elastically deformed in the diametrical direction. , the structure is such that the stone is received via this leaf spring.

<Function> In the above structure, even if the stones differ slightly in size, the stones are pushed into the C-shaped leaf spring that can be elastically deformed in the direction of diameter expansion, absorbing the difference in stone size, and using the elastic force of the stones. Therefore, the stone can be tightened and fixed.

<Example> An example of the present invention will be described below based on FIGS. 1 to 4.

In this embodiment, a case where the device is used as a pendant head will be explained.

First, a first embodiment will be described based on FIGS. 1 to 3.

FIG. 3 shows a lower conical stone 2 set in the stone holder 1 in an open state.

The stone holder 1 mainly consists of a bottom member 3 and a lid member 4, the bottom member 3 and the lid member 4 are connected by a connecting part 5, and are closed and fixed by a hook part 6. There is.

The connecting part 5 consists of an upper ring part 5a and a lower branch part 5b, and the bottom member 3 and the lid member 4 can be opened and closed by passing the pin 5c from the lower branch part 5b through a pin hole provided inside the upper ring part 5a. It is connected.

Further, a chain can be passed through the ring of the upper ring portion 5a.

Moreover, the hook part 6 consists of an upper claw 6a and a lower catch part 6b, and can be closed and fixed by pressing the lid member 4 downward.

Note that the lid member 4 has a frame shape, and is adapted to press and fix the outer periphery of the stone 2 when closed.

Referring to FIGS. 1 and 2, the bottom member 3 has a frame shape, and a C-shaped leaf spring 8 is disposed above the inner circumferential wall 7. This leaf spring 8 has a cylindrical shape with an axis in the direction of pressing the stone, has a slot 8a parallel to the axis, is elastically deformable in the diametrical direction, and has a side portion 8b in the circumferential direction to support the bottom member 3. It is fixed to the stop portion 3a.

Further, a tapered portion 7a that narrows downward is formed approximately in the upper half of the inner circumferential wall 7.

In use, when the stone 2 is placed on top of the leaf spring 8 and the lid member 4 is closed and fixed, the stone is pushed down slightly by the lid member 4 while expanding the diameter of the leaf spring 8. As a result, the stone receives a downward force from the lid member 4 on the upper side, and receives an upward force on the conical lower side while being sandwiched by the elastic force of the leaf spring 8.

Therefore, even if the stones are slightly different in size, the difference in size is absorbed by the leaf spring 8 and the stones can be completely fixed.

Furthermore, the formation of the tapered portion 7a prevents the leaf spring 8 from being seen from below, and further assists the smooth movement of the leaf spring 8.

Next, a second embodiment will be described based on FIG. 4, but substantially the same parts as those in the first embodiment will be denoted by the same reference numerals, and a description thereof will be omitted.

Projections 8c protruding toward the outer circumference are formed at both ends of the leaf spring 8 across the slot 8a, and the tips thereof are inserted into grooves 3c extending in the projecting wall 3b of the bottom member 3 in a direction perpendicular to the axis. When the plate spring 8 is moved in the diametrically expanding direction, the tip of each protruding piece 8c can slide within the groove 3c.

With this, a similar effect can be obtained, and furthermore, distortion in the axial direction can be avoided without impairing the original function of the leaf spring 8, making it advantageous in terms of strength.

<Effects of the invention> As explained above, according to the invention, a cylindrical C-shaped plate spring that is partially fixed to the bottom member in the circumferential direction and can be elastically deformed in the radial direction can be used to compensate for differences in the size of stones. Since it absorbs and tightens and fixes stones, it is possible to prevent the stones from wobbling even if the stones are of slightly different sizes.
