DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a fastener attached to an object such as a garment, and to an ornamental device such as an accessory using this fastener.
BACKGROUND ART
In recent years, accessories such as broaches have been designed to evoke the aesthetic sense of the accessory body to add to the impression of value brought about by diamonds or pearls. In a fastener for attaching the accessory body to an article of clothing, it is required that the fastener have a construction which excels in at least functionality in order to improve its fastening capability.
Three types of fasteners will now be described as typical examples.
FIG. 1A is a side view showing the construction of a broach according to a first example of the prior art, FIGS. 1B-1D are side views showing the manipulating procedure according to the first example of the prior art, FIG. 2A is a front view showing the construction of a principal portion of a broach according to a second example of the prior art, and FIGS. 2B-2D are front views showing the manipulating procedure according to the second example of the prior art.
As illustrated in FIG. 1A, the first example of the prior art is exemplified by a broach 1 in which a fastener 3, which has the construction and function of a safety pin, is attached to the bottom portion 2a of a main body 2. The safety pin-type fastener 3 is constructed in such a manner that one end 5b of a pin 5 is wound about a shaft 4 to form a spring, while the other, free end 5a of the pin is biased in a direction, which is indicated by arrow D1, against a force from the direction indicated by arrow U1. When the broach is not being used or has been attached, the other end 5a is received in an accommodating portion 3c formed into a frame-shaped configuration. Part of the accommodating portion 3c includes a freeing portion composed of a tongue portion 3a and a tongue portion 3b in order that the pin 5 may be taken in and out.
As for the method of manipulating the first example of the prior art, the user first applies a force to the pin 5 in the direction of arrow U1 starting from the state of the broach shown in FIG. 1A to urge the pin upward to the positions of the tongue portions 3a, 3b (FIG. 1B). Owing to this external force, the pin 5 produces a biasing force in the direction of arrow D1. Next, with the broach in the state shown in FIG. 1B, the user passes the free end 5a through the tongue portions 3a, 3b and removes the force in the direction of arrow U1 when the free end 5a emerges from between the tongue portions. The state of the pin shown in FIG. 1C is thus obtained. The user then passes the pin 5 through a garment 6 at a desired position thereof, after which the free end 5a is placed in the pin accommodating portion 3c in accordance with a procedure which is the reverse of that followed when the free end 5a of the pin 5 was extracted from the pin accommodating portion 3c.
In this first example of the prior art, the free end 5a is extracted from the pin accommodating portion 3c (FIG. 1C) and the pin 5 is passed through the garment 6 (FIG. 1D), after which the free end 5a is again urged upward toward the main body 2 to obtain the accommodated state of the free end 5a illustrated in FIG. 1A. Such manipulation is troublesome for the user to perform. More specifically, operations for extracting and accommodating the free end 5a are performed for a single fastening operation, and thus poor functionality resulting from these two tasks is conspicuous. Of course, the same troublesome-operations are performed also when the broach 1 is detached from the garment 6.
As illustrated in FIG. 2A, the second example of the prior art is exemplified by a broach 11. As in the first example of the prior art, a fastener 13, which has the construction and function of a safety pin, is attached to the bottom portion 12a of a main body 12. As in the first example of the prior art, the safety pin-type fastener 13 is constructed in such a manner that one end 15b of a pin 15 is wound about a shaft 14 to form a spring, while t
