Description

Catch device for ball chains {Cement Binder Based Plate}

The present invention relates to a clasping device for hanging a ball chain formed by balls connected in series with one another.

Hereinafter, in addition to the metal ball chain used as a key holder or the like, a tie belt made of synthetic resin or the like is also commonly referred to as a ball chain.

Ball chains are often used in key holders. The ball chains allow the keys to pass through and both ends of the ball chains are connected to each other by removable joint members to form an annular shape to hold the keys.

In addition, the ball chain is attached with ornaments such as character dolls or small items. Thus, although the original use of the key holder is to hold the key, sometimes the ball chain of the key holder hangs on belongings such as a bag as a mascot.

The use of ball chains is limited to such a range and lacks interest and attraction to stimulate purchase. In addition, the display of the ball chain is unexpectedly annoying because the ball chain is manufactured in a ring shape and must be suspended from a pin or the like.

The present invention has been accomplished in view of the foregoing, and one object of the present invention is to provide a locking device for a ball chain that can be played with the ball chain like a toy and easily displayed.

In order to achieve the above object, according to the present invention, in the latching device for a ball chain formed by the balls connected to each other continuously, having a central hole narrower than the diameter of the ball of the ball chain and the incision from the outer edge to the center hole A locking device including a locking piece of elastic plate is provided.

The ball chain is fitted into the center hole of the locking piece through the incision and caught by the locking piece at a position between two adjacent balls. In this state, when the outer edge of the locking piece is held by hand and the ball chain is pulled in one direction, the balls of the ball chain sequentially pass through the center hole while expanding the hole by elastic deformation, and the locking piece is after the ball passes. A click is generated when the engaging piece is elastically restored to its original shape. Since a plurality of balls pass one by one, intermittent light clicking sounds bring a pleasant mood to the player.

A catch piece attached to the ball chain can be used to suspend the ball chain so that the ball chain can be conveniently displayed.

If the locking piece is conical and has its center hole as a circular hole at the vertex, the locking piece is stably attached to the ball chain at the center hole, and the ball chain is pulled so as to pass the locking piece toward the vertex on the larger diameter opening side of the cone. In the event of a loss, the ball chain naturally enters the hole without deviating to the side to facilitate handling. This also applies to the case where the locking pieces are bowl-shaped or pyramid-shaped.

By making the locking piece made of synthetic resin, a locking piece having appropriate elasticity can be obtained and a more pleasant click can be produced. Moreover, as a product, a colorful, attractive and improved locking piece can be obtained.

A ball chain that is hooked by a locking piece and attached at one end with an article, such as a doll, can be used as a mascot or toy that generates a click.

A ball chain that has a joint member at one end and can be manufactured in an annular shape by detachably connecting the other end to the joint member can be used as the key holder.

If the ball chain passes through a small hole formed in the article and the joint member at one end of the ball chain is caught by the small hole to suspend the article, the ball chain caught by the catching piece can be used as a key holder with jewelry In this case, the engaging piece attached to the ball chain at the portion opposite the joint member with respect to the article can be used to prevent the article from falling out of the ball chain or to easily hang the article at the lower end of the ball chain.

According to another aspect of the present invention, there is provided a locking device for a ball chain formed by balls continuously connected to each other, comprising a locking piece for hanging a ball chain to which an article is attached, and a holding structure for holding the locking piece, The retaining structure includes a fitting depression for fitting and retaining the catch piece, a hole formed in the depression, and a cutout from the outer edge of the retaining structure to the hole so that the ball chain hangs the article at the lower end of the ball chain. A locking device is provided which extends downwardly through the hole for the purpose.

In such an apparatus, an article positioned below is suspended on a ball chain caught by the engaging piece, and the ball chain portion between the engaging piece and the article passes through the cutout portion, so that the engaging piece is fitted into the fitting depression. Therefore, the locking piece can be easily held for hanging the article, and the removal of the locking piece is also easy to facilitate the display of the plurality of articles.

With the article suspended from the holding structure by the ball chain, when the article is pulled down, the balls of the ball chain sequentially pass through the holes of the catch and generate a light click.

If the fitting depression is conical, and a hole is formed at the apex of the conical depression, and the conical locking piece having a center hole at the apex is fitted and retained in the fitting depression, the locking piece can be held stably, The work for fitting can be done easily and surely.

Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. In the present embodiment, the present invention is applied to the key holder 1 using the ball chain 2, which is shown in its entirety in FIG.
