Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circumference measuring tool used for size adjustment of bracelets, necklaces and the like.

[0002]

2. Description of the Related Art Conventionally, when a bracelet is sold, the length of the chain is adjusted according to the thickness (perimeter) of the wrist. The thickness of the wrist is usually measured using a measuring tool such as a tape measure or a band with a scale (see, for example, Japanese Utility Model Laid-Open No. 55-150302).

However, when measuring the circumference of the wrist, a gap is likely to be formed between the wrist and the measuring tool, which makes the measurement inaccurate, and it is difficult to adjust the bracelet to the optimum size. It was In particular, the degree of slackness of the bracelet cannot be understood until it is actually attached to the wrist, so it is necessary to repeat the length adjustment of the bracelet many times, which is troublesome.

On the other hand, when selling a necklace, the length of the chain is adjusted according to the neck circumference, height, etc. However, as long as the necklace is actually worn around the neck,
Since I did not know the proper size of the necklace, it was necessary to repeat the chain length adjustment many times, which was troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a perimeter measuring instrument which can easily and quickly adjust the size of a bracelet, a necklace or the like.

SUMMARY OF THE INVENTION In order to achieve the above object, the circumference measuring tool of the present invention comprises a ring made of a flexible wire, and both ends of a plurality of chain-shaped bodies having different lengths. Is slidably inserted along the circumferential direction of the ring.

According to this circumference measuring tool, each chain and the ring can form a loop having a circumference corresponding to the length of each chain for each chain. Further, the size of each loop can be arbitrarily adjusted by bringing the ends of the corresponding chain-like bodies into contact with each other along the ring. Therefore, by expanding the desired loop, it is possible to insert a measured part such as a wrist or a neck into the inside, and in this inserted state, by pulling the ends of the chain-like bodies forming the loop, In other words, by narrowing the loop,
It is possible to create a state where bracelets, necklaces, etc. are actually attached. As a result, the proper size of the bracelet, necklace, etc. can be easily grasped.

In the circumference measuring tool having the above structure, it is preferable that the surface of the ring is covered with resin.
In this case, the relative sliding between the ring and the end of the chain can be performed very smoothly.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a front view showing one embodiment of the circumference measuring tool of the present invention. This perimeter measuring tool is used for size matching of a bracelet, and a ring 1 made of a flexible stranded wire 11 is provided with both end portions 21 of a plurality of chain-like bodies 2 having different lengths. , Is slidably inserted along the circumferential direction of the ring 1.

The ring 1 has a resin coating 10
Both ends of the wire 11 (see FIG. 2) having been applied are introduced into an aluminum tube 12, and the tube 12
By crimping, the both ends are connected to form a ring. The flexibility of the ring 1 is set such that the ring shape can be maintained in a free state and can be easily deformed when pressed by hand.

The chain-like body 2 is such that a metal tag 23 indicating the entire length of the chain-like body 2 is suspended at the folded end of a thin chain 22 which can easily follow the wrist. Locking wheels 24 for passing the ring 1 are connected to both ends 21. Although not shown, each chain 2 is provided with twelve, and the total length is, for example, 1 cm.
The distance is set in the range of 14 to 25 cm.

With the above structure, the chain L and the ring 1 can form a loop L having a circumferential length corresponding to the length of each chain 2. Further, the size of the loop L can be arbitrarily adjusted by bringing both end portions 21 of the corresponding chain-like body 2 into contact with each other along the ring 1 and separating them. Therefore, while pushing out the desired loop L,
The hand A can be inserted therein (see FIG. 3).
At this time, since the ring 1 can be bent in an arc shape, the hand A can be inserted very easily.

Then, after inserting the hand A into the loop L, the bracelets are actually put on the wrist B by pulling the ends 21 of the chain-like bodies 2 constituting the loop L together, that is, by squeezing the loop L. It is possible to create a state attached to (see FIG. 4). Therefore, it is possible to easily know how loose the bracelet is. Therefore, if necessary, the above operation can be repeated to easily grasp the optimum length of the bracelet. That is, the size of the bracelet can be easily and quickly adjusted.

In order to squeeze the loop L, the chain-like body 2
The ring 1 may be twisted by rotating the ring 1 a half turn so that the ends 21 of the two intersect. When the loop L is squeezed, the resin coating 10 of the ring 1 can smoothly draw the two end portions 21 of the chain-like body 2 that have been separated from each other. Also, when the loop L is widened, the chain-shaped body 2 is made by the resin coating 10 of the ring 1.
It is possible to smoothly separate the two end portions 21 of each other.

The perimeter measuring tool of the present invention can be used for necklace size adjustment by setting the total length of each chain 2 to 40 to 80 cm at intervals of, for example, 3 to 5 cm. Also in this case, since it is possible to create a state in which the necklace is actually worn around the neck, the size can be adjusted easily and quickly.

The circumference measuring tool of the present invention is not limited to the above embodiment, and for example, the surface of the ring 1 is covered with a resin tube instead of the above resin coating, and the tag 23 is chain 22. Various design changes can be made, such as interposing in the middle of the.

[0017]

As described above, according to the circumference measuring tool of the present invention, the chain can create a state in which a bracelet, a necklace or the like is actually worn.
There is a unique effect that the size can be adjusted easily and quickly. In particular, when the surface of the ring is covered with a resin, the relative sliding between the ring and the end of the chain can be performed very smoothly, so that the handling operation is very easy. It has a unique effect of being easy.
