Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a precious metal chain for personal accessories used for necklaces and the like.

[Conventional technology]

Necklaces and other accessories made of precious metals such as platinum and gold are extremely important in terms of overall design.

As an example of such a necklace, as shown in FIG. 8, when vertically-arranging longitudinal members 1 are connected in a lateral direction to form a comb-shaped noble metal chain, the longitudinal member 1 is made of platinum or gold. If it is a bar member made of noble metal, there is a method of making a hole penetrating the side of the bar member and inserting a thin cord or chain 2 into the hole.

In this method, the structure for fixing the longitudinal member 1 to the string or the chain 2 so as not to move is troublesome, and the string or the chain 2 is limited to a comparatively thin one.
There remains anxiety that it is easy to cut.

As another method, as shown in FIG. 9, a ring body 3 for a chain is provided on the upper portion of the vertically elongated member 1 by brazing and the ring bodies 3 are connected to each other, or as shown in FIG. An enlarged end 4 of a connecting member 4 formed by a fireball inside the vertically long member 1.
There is a method of inserting a.

[Problems to be solved by the device]

However, the structure shown in FIG. 9 has a drawback that the ring body 3 for the chain and the upper portion of the longitudinal member 1 are easily cut off,
In addition, the wax eye of the brazing part may be discolored and the appearance may be damaged.

Further, in the structure shown in FIG. 10, the connecting member 4 and the vertically long member 1 are provided.
Connection work with is extremely troublesome and workability is poor.

The present invention eliminates the inconveniences of the conventional example, and is a novel design chain, has excellent strength with no easy-to-cut parts, and also has a good appearance because the brazing point etc. are not exposed to the outside. An object of the present invention is to provide a precious metal chain for personal accessories that is easy to assemble and has good workability.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a case in which side-by-side longitudinal members are connected to each other to form a comb-shaped noble metal chain. The protruding portion of an H-shaped connecting piece having a protruding portion protruding in the vertical direction is inserted into the cylindrical body through the slit, and the cylindrical body is vertically inserted into the gap between the protruding portion and the peripheral surface of the cylindrical body. The end of the washer cylinder made of a short cylinder inserted from the opening of the washer is inserted, and the other end of the washer cylinder is abutted and fixed by the tips of the cylindrical caps inserted from the upper and lower openings of the cylinder. It is what

[Action]

According to the present invention, the H-shaped connecting piece inserted into the cylindrical body as the vertically long member through the slit is prevented from coming off by interposing the washer cylinder inside the cylindrical body.

In this way, the interlocking cylinders can be connected to each other in the lateral direction to form the interdigital noble metal chain.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of a one-piece portion showing an embodiment of a precious metal chain for personal accessories of the present invention, and FIG.
FIG. 3 is an exploded perspective view.

First, the components will be described. The present invention uses a noble metal cylindrical body 5 having openings at the upper and lower ends as a vertically elongated member. The cylindrical body 5 is made of platinum as an example, and the upper and lower portions are slightly bulged in order to exert a design effect, and the central portion is formed in a polygonal cross section so that the corners are formed like vertical stripes.

Slits 5a are vertically formed on both left and right sides of the cylindrical body 5.

Reference numeral 6 in the figure denotes a connecting piece of these cylindrical bodies 5, which is made of a flat plate made of gold (14K, 18k), and has protruding portions 6 on both left and right sides in the vertical direction.
The entire a formed is H-shaped. This protrusion 6
The length between the upper and lower ends of a is a little shorter than the length of the slit 5a.

Reference numeral 7 is a washer cylinder made of a short cylinder, which is also made of a noble metal such as platinum, and its outer diameter is substantially equal to the inner diameter of the cylinder 5.

8 is a cylindrical cap, which is made of gold (14K, 1
8k), and the cylinder diameter is the same as the washer cylinder 7.

In this way, the protruding portion 6a of the connecting piece 6 is inserted into the cylindrical body 5 through the slit 5a, and then the washer cylindrical body 7 is inserted.
Is inserted from the upper and lower openings of the cylindrical body 5 and the end thereof is put in the gap between the projecting portion 6a and the inner peripheral surface of the cylindrical body 5.

As a result, the protruding portion 6a fits within the washer cylinder 7, and the washer cylinder 7 has its outer periphery fitted to the inner periphery of the cylinder 5 to close the upper and lower sides of the slit 5a.

Therefore, due to the presence of the washer cylinder 7, the connecting piece 6 has the protruding portion 6a.
Serves as a locking piece and does not come out of the cylindrical body 5.

It should be noted that the connecting piece 6 has a certain degree of slidability such that the connecting piece 6 is deeply inserted into the cylindrical body 5.

After the washer cylinder 7 is inserted, the cylindrical cap 8 is inserted from the upper and lower openings of the cylinder 5 as well.
The end of the washer abuts against the end of the washer cylinder 7.

In this case, the length of the cylindrical cap 8 is
It is desirable that the closed end side of the upper portion has such a length that it projects from the upper and lower sides of the cylindrical body 5.

By doing so, the gold color of the cap 8 is exposed vertically with respect to the silver color of the cylindrical body 5, and a novel two-tone color tone is obtained, and also the gold color of the connecting piece 6 is achieved.

When the cylindrical cap 8 is fixed to the cylindrical body 5 by brazing or the like, the washer cylinder 7 is formed by the cylindrical cap 8 and the cylindrical body 5.
It will be trapped inside and there will be no need to braze itself.

As described above, the connecting piece 6 sequentially connects the cylindrical bodies 5 in the lateral direction to form a comb-shaped chain which is a vertically long member in which the cylindrical bodies 5 are arranged in parallel. As shown, the clasp male part 9a made of gold (14K, 18k) is attached to each end.
And the clasp female part 9b is provided to complete the necklace.

It should be noted that various kinds of noble metals to be used and what kind of tint can be selected, and the above embodiment is merely an example.

In addition, various fine shapes of the cylindrical body 5 and the connecting piece 6 can be similarly selected.

Furthermore, the washer cylinder 7 does not come out at all,
It is also possible that only this is not a precious metal.

[Effect of device]

As described above, the precious metal chain for accessory of the present invention is
When connecting vertical members that are parallel to each other in the lateral direction to form a comb-shaped noble metal chain, this chain has a novel design, has no strong parts, and has excellent strength. Since it is not exposed to the outside, it has a good appearance and is easy to assemble and has good workability.
