Below the suitable embodiment of decorative chains structure of adjusting length of the present invention is described.

Fig. 1～decorative chains structure of adjusting length shown in Figure 3 has 1 kayser that is fixed on the ornament.

This kayser 10 is made of shell 1 and the tubular elastic component 4 that is built in this.

Shell 1 is made in illustrated embodiment and is roughly drum, but can be that outer surface is a shape arbitrarily such as polyhedral, egg shape or circle, preferably can insert the object of logical decorative chains 2.

Decorative chains 2 is the chains that constitute necklace or bangle etc., is made of the chain of ball chain or red bean shape and the chain of other known shape.

Lead in the kayser 10 for this decorative chains 2 is inserted, on shell 1, be provided with through hole.

That is, the hole 3a of insertion decorative chains 2 one sides and the hole 3b that decorative chains 2 connects away a side are arranged on shell 1.

This shell 1 is cut into specific length with metal tube shown in Fig. 1 (c), as Fig. 1 (d) with the two ends rounding.

In the cylinder that forms like this, insert elastic component 4 described later, shown in Fig. 1 (e),, form hole 3a, the 3b of minor diameter further towards riveting or push the two ends of above-mentioned chamfering.

The diameter of this

hole

3a, 3b only is designed to than its periphery more greatly, so that decorative chains is slided glibly.

Elastic component 4 is made of columned spring, and this columned spring is that the curving like that shown in Fig. 1 (b) of 1 metal latch plate shown in Fig. 1 (a) is cylindric, and the seam of central authorities has the crack 5 of the slit-shaped that linearity extends.

The internal diameter of this elastic component 4 is designed to littler than the outer circumference diameter of decorative chains 2, with box lunch decorative chains 2 is passed through when being inserted in the inside, and effect has spring force on the direction of the periphery that clamps this decorative chains 2.

The openings at two ends of this elastic component 4 is respectively to insert the hole 4a of decorative chains 2 one sides and the hole 4b that decorative chains 2 connects away a side.

And elastic component 4 is with the metal material full circle, make cylindric, so can be because of the heat function that follows the string.

Therefore, add heat energy for other shell or decoration and other parts and make its joint (welding).

If with decorative chains 2 slotting leading in the elastic component 4, because making elastic component 4 expand towards the direction that enlarges, opens the outer peripheral face of decorative chains 2, so elastic component 4 itself suppresses to the direction of dwindling.

Therefore, insert the decorative chains 2 in the elastic component 4, owing to clamped by the spring force of elastic component 4, so always clipped by elastic component 4.

At this, elastic component 4 is accommodated in the cavity of kayser 1, and the bore dia of the above-mentioned discrepancy usefulness of kayser 1 is less, is designed to elastic component 4 and pulls out to come out.

As shown in Figure 2, if spur decorative chains 2 arbitrarily, then elastic component 4 is hauled action simultaneously, and the inwall of the end of elastic component and kayser 1 collides, and motion is limited.

If pull at decorative chains again, then revolt elastic component 4 spring force, expand and open elastic component 4 and only have decorative chains to be drawn out simultaneously.

Therefore, its length is pulled out, regulated to kayser with decorative chains relatively.

If oppositely draw decorative chains, then elastic component 4 counter motion in kayser collides with the inwall in the hole of an opposite side, with above-mentioned same, elastic component can be expanded open simultaneously decorative chains is oppositely pulled out.

Structure shown in the foregoing description as shown in Figure 3, hangs on the clasp 20 by the end of joint 21 with 1 decorative chains, can regulate the length of multiterminal portion by kayser, but kayser shown in Figure 4 can carry out length adjustment to a plurality of decorative chains.

This kayser 10 is made of following structure: many (illustrated embodiment is 2) decorative chains 2 of setting-in side by side in shell 1, embedding elastic component 4 outside distinguishing shell 1 in, on each decorative chains 2.The occasion of example shown in the figure for ease of explanation, is being provided with a plurality of identical components subscript symbols " ＇ " to show difference herein.

That is, on shell 1, opposed paired

hole

3a, 3a ＇ and 3b, the 3b ＇ of being formed with at two ends.

And, dispose elastic component 4,4 ＇ between each

hole

3a, 3b and between 3a ＇, the 3b ＇, and embedding 2 decorative chains arranged side by side, 2,2 ＇ that connect above-mentioned

hole

3a, 3a ＇ and 3b, 3b ＇.

This decorative chains 2,2 ＇ both can roll use with 1 decorative chains, also can be many uses side by side.

This occasion also can be regulated length separately by drawing each decorative chains 2,2 ＇.

Shown in Figure 5 is to carry out the kayser of length adjustment to many (4) decorative chains.

This occasion is also same with the foregoing description, and 4

hole

3a, 3b respectively are set on 1 shell 1, uses the hole as the gateway, and is corresponding respectively with it, is provided with 4 elastic components 4.Because other member is same as the previously described embodiments, so omit its explanation.

The kayser 10 of Fig. 6 is made of a plurality of shell 1A, the 1B that link together separably, and in each

shell

1A, 1B built-in flexible 4, decorative chains 2,2 ＇ that are inlaid in each

shell

1A, 1B are slided, can carry out length adjustment.

On

shell

1A, 1B, be respectively equipped with coupling apparatus or bridging arrangement, and the parts separately of other separable jockey, it can be linked into an integrated entity separably.

For example can adopt hook and take in the structure of the structure of the receiving portion of hook, concavo-convex combination, structure and other various structures of application magnet absorption.

This kayser 10 can be used for necklace of tie type for example etc.

In this occasion, separately

shell

1A, 1B can be separated, unload necklace, also can make

shell

1A, 1B connect to one or under released state, draw decorative chains 2 separately to carry out length adjustment.

Elastic component 4 shown in Figure 7 is provided with prominent protrusion 7 to the inside on its perisporium.

This protrusion 7, the occasion of example shown in the figure are roughly to make ring-type along periphery, but also can be not swell continuously along periphery, but swell intermittently.

Therefore, even do not contain with the pearl of the big three-dimensional shapes such as spheroid of the contact area of elastic component and occasion that only be made of the chain of ring-type, for example red bean shape etc. in decorative chains, protrusion 7 also can collide with chain, acts on spring force reliably.

Elastic component 4 ＇ shown in Figure 8 are because crack 5 ＇ of its slit-shaped are along the axis direction inclination of relative resilient part 4 ＇ and to the length direction extension, so even be formed with corner angle on the pearl of decorative chains, also be difficult for being embedded among 5 ＇ of crack.

In addition, elastic component 4 ＇ shown in Figure 9, crack 5 ＇ of its slit-shaped bend to wavy and extend to length direction.

If like this, for example, not spherical but square occasion at the pearl of decorative chains 2 ＇, the crest line that the linearity of its side extends can not be embedded among 5 ＇ of crack.

The shape in crack of the present invention can be done suitable change according to the shape of decorative chains, can adopt oblique inclination, suitable shape such as sinuate.

In addition, flange is set in the end of elastic component or increases thickness, though preferably make its shell Kong Bianda elastic component pull out to come out yet.

Generally speaking, yes can carry out various change designs in the scope that does not change main points of the present invention.

As previously discussed, the structure of adjusting length of the decorative chains of this invention owing to be embedded in elastic component on the decorative chains outward and make it restricted, so enlarged cramping area with decorative chains, has improved not easy damaged of clamping force and decorative chains.
