Description

[Detailed Description of the Invention] This invention relates to the disclosure of a decorative chain structure that has good appearance characteristics and is inexpensive to assemble.

Therefore, in the past, when assembling this type of chain, the individual chain components were often connected sequentially via a connecting ring, etc., and each component of the chain was connected on the same plane. This is intended to enhance the decorative effect by connecting the parts.

However, in such a method, a lot of time and effort is required for inserting the ring, caulking or brazing, etc., and the assembly production cost is relatively high.
The interposed connecting ring dilutes or flattens out the decorative characteristics of the chain, making it impossible to obtain a satisfactory decorative effect compared to the amount of precious metal used.

Recently, as a connection technique commonly used for the purpose of avoiding the inconveniences in such basic connection methods, the structural units of the chain are successively connected directly to each other, and this is used as a decorative chain and enhances the hobby. However, in such a method, it is difficult to assemble the connected constituent units in a two-dimensional manner, and the simplicity and elegance of the connected chains themselves are compromised. It is often damaged.

In addition, such a connection method requires special techniques and a lot of labor for assembly, and is prone to accidents such as assembly errors, especially incorrect assembly direction. This caused accidents such as a rough feeling when using the chain and the chain coming off when caught.

The decorative chain according to the present invention has been specially devised in view of the inconveniences in the prior art. When directly assembling the chains, the feeling of roughness between the constituent units is eliminated, and the chain units constituting all the chains can be assembled within the same plane level.

The decorative chain according to the present invention has a structure in which, in order to achieve the desired effects of these various characteristics, the decorative chain is arranged so as to face each other at a predetermined interval in the structural unit a of the decorative chain. The other end face opposite to the protruding end face 1a at one end thereof is shaped like a cutout 2b, and the protruding end face 1a is connected to the cutout 2b.
The end surfaces 1a and 2 are cut out from the side in the shape of a split 1b.
The rod 3 connecting the ends 1a and 2a is provided at a point that projects slightly laterally from the overlapping base line of the end surfaces 1a and 2a. Considerable design changes are planned.

A typical embodiment of the decorative chain according to the present invention will be described below with reference to the attached drawings.
...a is a single piece as a chain bead that constitutes a chain, and the shape, dimensions, etc. of the single piece a that constitutes one chain are generally the same.

In particular, the single piece a shown in the illustrated example is considered unsuitable for molding with a casting mold due to its shape characteristics, and was planned to be molded using the lost wax method, which would reduce the molding cost and It is planned to be mass-produced as a single unit with a particularly good hand-made aesthetic appearance.

Such a unit a has protruding end surfaces 1a, 2a for connection and cutouts 1b, 2b facing each other through a gap for predetermined engagement at the ends in the connecting direction, and the respective protruding end surfaces 1a , 2a are connected by a rod 3.

That is, one end x of the unit a is configured with an upper plate 1 and a lower plate 2 which is disposed opposite to each other with a predetermined distance therebetween, and a part of the upper plate 1 is connected to the protruding end surface 1a. At the same time, the corresponding lower plate 2 surface is cut out 2b, a part of the lower plate 2 is made into a protruding end surface 2a, and the corresponding upper surface plate 1 surface is cut out 1b, and the respective protruding end surfaces are made. It is configured such that 1a, 2a and cutouts 1b, 2b are arranged in series.

In addition, the unit a in the illustrated example is the top plate 1.
and the lower plate 2 are connected by a rod 3 or the like to form a two-lobed structure, but the end x portion provided for connection in the single unit a has an end face shape that is divided into upper and lower halves. Of course, this is also an effective method, and the configuration example is determined at any time depending on the decorative function of the target chain.

The overlapping protruding end portions of the protruding end surfaces 1a and 2a of the respective plates 1 and 2 having such a configuration are connected by the rod 3, and the rod 3 is placed slightly to the side of the overlapping surface of the end surfaces 1a and 2a. It is constructed so as to protrude in the direction, and is easily joined to the next component unit a to be connected, especially the protruding end surface 1.
a, 2a and the protruding end surface 1 of the next component a
a and 2a can be joined without overlapping each other.

In addition, the other end y of the unit a has a configuration opposite to that of the end x, with the end face 1a fitting into the cutout 1b and the end face 2a fitting into the cutout 2b, respectively.
It goes without saying that the end surfaces 1a and 1a are constructed so that the end surfaces 2a and 2a do not overlap with each other.

The decorative chain according to the present invention has a unique configuration as described above, in which the rod 3 of the next unit a is inserted deep inside from the separated position, with the rod 3 partially separated. The separated parts can be easily assembled and connected by fixing them with wax or the like.

The decorative chain of the present invention having such a configuration can be assembled by an extremely simple method of engaging the laterally protruding rods 3, 3 with each other, thereby reducing the assembly cost and ensuring a reliable chain. It is a promise to be attached.

Further, the protruding end surfaces 1a, 2a and the cutouts 1b, 2b are provided in positions that allow them to intervene with each other, and the protruding end surfaces 1
a and the protruding end surface 2a of the next unit a do not overlap each other, and basically the end surface 1a
and 1a, and 2a and 2a are the respective cutouts 1b and 2
The decorative elements a, a, .

Furthermore, the surfaces of the other plates 1 and 2 corresponding to the cutouts 1b and 2b are not necessarily the protruding end surfaces 1a and 2.
Since it is set as a, a metal surface is always present as a chain even on the cutouts 1b and 2b, making it possible to provide a decorative chain with a sufficient sense of mass compared to the amount of metal used. It is.

Reducing the amount of materials used without sacrificing the luxury of the external appearance is particularly important in precious metal ornaments, and the upper plate 1 and lower plate 2 in the illustrated example are of particular importance. The intention was to create a complete space between them.

The chain constructed as described above is able to meet the demands for decoration of such precious metal chains, and the chain bodies with a predetermined wall thickness can be seen from the surface of the connected chains. It could only be recognized as a continuum.

As mentioned above, the present invention provides a decorative chain that has good assembly properties, eliminates the roughness of the assembly chain, ensures a smooth flowing feeling, and exhibits a luxurious chain surface. The purpose is to
