Abstract

A ring diameter variator for a ring-shaped accessory is provided with: a case (3) having first and second outlets (9a, 9b) at both end portions; a reel (4) rotatably housed within the case (3); first and second adjusting straps (5a, 5b) which are each wound in the same direction onto the reel (4) and pulled out to the outside from the first and second outlets (9a, 9b) and connected to one end and the other end of the ring-shaped accessory (1); and a spiral spring (6) which rotationally biases the reel (4) in the winding direction (A) of the first and second adjusting straps (5a, 5b). As a result, it is possible to provide a ring diameter variator for a ring-shaped accessory which can extend ring diameter sufficiently while having superior appearance.

Description

technical field [0001] The present invention relates to an improvement of a ring-diameter variable device for a ring-shaped ornament, which is connected between one end and the other end of a ring-shaped ornament such as a necklace or a bracelet, and used to make the ring diameter of the ring-shaped ornament variable. Background technique [0002] Most ring-shaped ornaments have joints for putting on and taking off the body, but the separation and connection operations of such joints are extremely cumbersome. Thus, for example, as disclosed in Patent Document 1, a ring-diameter variable device for a ring-shaped ornament has been proposed, which makes the ring diameter of the ring-shaped ornament variable, and when it is worn on the body, its ring diameter is enlarged. diameter for ease of wearing, and restores its ring diameter to its normal condition after wearing it.
