Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a fastener for an accessory.

<Problems to be solved by this device> As an improvement of fasteners for jewelry such as necklaces,
No. 60-121813 and 62-145515 have been proposed, but neither is easy to attach and detach, and the tension force applied to the detaching side when connected is small and small. Since it is received by the shaft, there is a problem that it may come off or break unexpectedly. The present invention is intended to solve such problems.

<Construction of the Invention> The present invention provides a doorway and a pulling ring having a spring push rod for opening and closing the doorway, a decorative body to be mounted on the pulling ring, and one side of the pulling ring inside fitting portion of the decorative body. The fastener for an accessory is characterized in that it has a protrusion formed by forming an insertion / removal hole for insertion / removal in the spring push rod.

<Example> An example will be described below with reference to the drawings.

A ring-shaped pulling ring 3 which has a doorway 1 and a spring push rod 2 for opening and closing the doorway 1 and which is hollow in plan view is formed. 4 is a spring for pushing the spring push rod 2, 5 is an operation botch, 6
Is a cutout portion, and 7 is a mounting portion with a mounting hole 7a at one end of the necklace N or the like. A disk-shaped ornamental body 8 having a size to be mounted corresponding to the wheel 3 is formed. The decorative body 8 has a shaft portion 8a as a portion that is tightly fitted in the pulling ring 3 at a lower portion, and a protruding portion 9 having a width that goes in and out of the doorway 1 is provided on one side surface of the shaft portion 8a, An insertion / removal hole 10 for the spring push rod 2 and a mounting hole 11 at the other end of the necklace N are formed in the projecting portion so as to cross the shaft portion 8a.
On the lower part of the other side, there is provided a hooking claw 12 which sneaks under the pulling wheel 3 and locks.

With the above configuration, when the ornamental body 8 is mounted on the pulling wheel 3 while pulling the operation botch 5 to open the entrance / exit 1 and allowing the latching claw 12 to sneak under the pulling wheel 3, the shaft portion 8a is pulled. 3 is tightly fitted in the inside, and in the process, the hook 12 is hooked under the pulling wheel 3,
The pull tab is released by guiding and fitting the protrusion 9 to the entrance / exit 1. The spring pushing rod 2 traverses the inside of the insertion / removal hole 10 and connects the decorative body 8 in a state where it is mounted on the pulling wheel 3. When the connection is released, the reverse operation is performed, that is, the botchi 5 is pulled and the ornament 8 is lifted. The connection will be released immediately.

FIG. 4 is the embodiment of FIG.
It is the same as the previous example except that it is formed as a dual-purpose body of 8b and the latching claw 12 is not provided.

<Effects of the Invention> Since the present invention is configured as described above, it is possible to connect the decorative body to the wheel by a simple operation, and when the connection is made, the decorative body or the shaft portion is closely fitted to the wheel. In addition, since the tensile pressure is applied to a wide range of the peripheral surface, there is an effect that it is not pulled out and broken without being caught.

Further, when the hooking claw is attached to the lower end of one side of the shaft portion, there is an effect that the hook is hooked below the pulling ring when the ornamental body is inserted and the vertical rotation of the ornamental body is prevented.

[Brief description of drawings]

FIG. 1 is a plan view showing a first embodiment of the present invention in a state in which fasteners are connected, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. FIG. 4 is a perspective view showing the body before connection, FIG. 4 is a perspective view showing the stopper of the second embodiment before connection, 1 is a doorway, 2 is a spring push rod, 3 is a pulling ring, 4 is a spring, 5 is an operating botch, 6 is a notch, 7
Is a mounting portion, 7a is a mounting hole, 8 is a decorative body, 8a is a shaft portion, 9 is a protruding portion, 10 is an insertion / removal hole, 11 is a mounting hole, and 12 is a hooking claw.

Claims (2)
