FASTENING AND ORNAMENT PROVIDED WITH THE SAME

Abstract: A fastening (33) of the invention is adapted to be fit to an ornament and has a structure wherein it is rotatably joined to an ornament (32), a needle (35) extends in one direction from the junction (39) while a lever (38) extends in the other direction therefrom, and the tip (35a) of the needle is forced towards the ornament (32) with a rotary shaft (34) of the junction (39) functioning as the center. The needle (35) is provided in the vicinity of its tip (35a) with a curved portion (35b) diverging from the ornament (32). According to this structure, the ornament can easily be fitted or removed by operating the lever (38). The curved portion (35b) serves to prevent unexpected fall of the ornament from the place to which it is fitted.

Description: 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 the other, free end 15a of the pin is biased in a direction, which is indicated by arrow D2, against a force from the direction indicated by arrow U2. when the broach is not being used or has been attached, the free end 15a is received in a pin accommodating portion comprising a disk-shaped stationary portion 16 provided on the distal end of a support 18, and a disk-shaped loose-fitting portion 17 which covers the surface of the stationary portion 16 and retains the stationary portion in a loosely fitted state. The loose-fitting portion 17 has a knob 17a projecting from a side face thereof. The user presses a finger against the knob 17a so that the loose-fitting portion 17 can be rotated on the surface of the stationary portion 16 in the direction indicated by arrow R1 (as well as in a direction opposite this arrow). When the loose-fitting portion 17 is rotated, openings 17b, 16b respectively provided on the loose-fitting portion 17 and stationary portion 16 can be made to coincide, as will be described later, so that the free end 15 of the pin 15 can be taken out along the openings 17b, 16b. As for the method of manipulating the second example of the prior art, the user first rotates the loose-fitting portion 17 in the direction of arrow R1 starting from the state shown in Fig. 2A, and brings the opening 17b of loose-fitting portion 17 and the opening 16b of stationary portion 16 into coincidence to obtain a pin extracting space 19 (Fig. 2B) for extracting the free end 15a. In this operation, the user holds the main body 12 with one hand while using the other hand to perform the manipulations that obtain the pin extracting space 19. The user then urges the free end 15a upward in the direction of arrow U2 and removes the force applied in the direction of arrow U2 when the free end is extracted from the openings 16b, 17b. The state of the free end 15a shown in Fig. 2C can thus be obtained. The user then passes the pin 15 through a garment 20 at a desired position thereof, after which the free end 15a is placed in the pin accommodating portion in accordance with a procedure which is the reverse of that folllowed when the free end 15a of the pin 15 was extracted from the pin accommodating portion. Thus, with the second example of the prior art, it is required that both hands be used to attach and detach the broach. If a hand-held bag is being carried when the broach is attached or detached, the bag must be put down temporarily. This is troublesome. In order to eliminate the aforementioned operation-related annoyances of the first and second examples of the prior art, Japanese Utility Model Publication No. 44-3926 (hereinafter referred to as the "third example of the prior art"), which was filed in Japan on November 24, 1964, discloses a clasp having an arrangement in which the rear ends of a base piece having a pin and of a base piece serving as a main body are connected in such a manner that the distal ends of both base pieces are directly mutually inward using the elastic force of a spring. In accordance with this disclosure, the biasing direction of the spring is directed toward the base piece on the main-body side opposite the biasing direction of the pins described in the first and second examples of the prior art. This is advantageous in that after passing the pin through the garment, the user need only remove the force holding the pin open. However, the base piece on the main-body side that receives the distal end of the pin is provided with a projection having a V-shaped notch, and the distal end of the pin is received by the notch. Consequently, it is possible that the garment through which the pin has been passed will readily reach the tip of the pin, and this can cause the tip of the pin to easily become detached from the projection. Accordingly, in the third example of the prior art, the arrangement for reliably holding the ornament in the fastened state is deficient. JP-Z-10164 discloses a fastener, including multiple pins, for attachment to a main body of an ornamental device such as a brooch. A lever-type operating member is provided attached to one end of the multiple pin array of the fastener and is designed to be pinched towards the main body of the ornamental device so as to separate the free ends of the multiple pins from the main body. Each of the multiple pins of this fastener includes a sloping portion at the free end thereof, sloping towards the main body of the ornamental device.

Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. [First Embodiment] Fig. 3 is a side view showing the construction of a broach according to a first embodiment, Fig. 4 is a front sectional view showing a cross section taken along line A-A' of the broach shown in Fig. 3, Fig. 5 is a side sectional view showing a cross section taken along line B-B' of the broach shown in Fig. 3. As illustrated in Fig. 3, a broach 31 according to the first embodiment basically includes a main body 32 and a fastener 33. The main body 32 has ornamental portions 32a, 32b on which ornaments such as a diamond or pearl are mounted. The fastener 3 comprises a lever 38, which has a mechanism for being attached to an article of clothing, and a pin 35. At its rear part the main body 32 has a connection portion 39 for freely rotatably supporting the lever 38 of the fastener 33 by a shaft 34. Furthermore, at least the surface of the main body opposite the pin 35 is provided with a pin accommodating portion 36 for receiving and accommodating a distal end 35a of the pin 35 attached so as to extend forwardly from the lever 38. The pin accommodating portion 36 has a U-shaped configuration and, as shown in Figs. 3 and 5, has acute-angled projections on the upper surfaces of downwardly extending side portions 36a, 36b. The overall length of the pin 35 is set depending upon the length of the main body 32. Further, the pin 35 has a curved portion 35b obtained by bending the pin near its tip end 35a toward the side of main body 32 with respect to the axial direction of the pin 35. Owing to the curve formed by the curved portion 35b, a pocket is formed between the pin 35 and the main body 32 so the broach 31 can be adapted to a garment having some thickness. The curved portion 35b forms a difference-in-level portion with respect to the axial direction of the main body of pin 35. As will be set forth later, this functions so as to apply a brake to shifting of a garment through which the pin 35 has been passed. A torsion coil spring 37 is attached at the connection portion 39 (Figs. 4 and 5), which axially supports the fastener 33, in such a manner that the pin 35 rotates about the shaft 34 in the direction indicated by arrow P2. End portions 37a, 37b of the torsion coil spring 37 are arranged so as to respectively come into pressured contact with a bottom portion 39a of the connection portion 39 and a bottom portion 38e of the lever 38. At this time the end portion 37b of the torsion coil spring 37 acts so as to rotate the lever 38, namely the fastener 33, clockwise in the case of Fig. 5. As a result, the distal end portion 35a of the pin 35 comes into pressured contact with a bottom portion 36a of the pin accommodating portion 36 serving as an obstacle in the direction of arrow P2. As shown in Fig. 4, the lever 38 and the connection portion 39 each have a U-shaped configuration. The U-shaped part of the connection portion 39 engages, in an inverted state, with the inner side of the U-shaped part of lever 38, whereby engaged portions are formed at two locations. These two engaged portions are formed to have a series of insertion holes by holes 38b, 38d provided in the lever 38 and holes 39b, 39c provided in the connection portion 39. When the shaft 34 is passed through the insertion holes, the end portions 37a, 37b of the torsion coil spring 37 are attached so as to point backwardly in Fig. 4. In order to make it easier to apply finger pressure, the lever 38 has a backwardly extending pressure-applying portion 38f, as illustrated in Figs. 3 and 5. There is no particular restriction upon the length of the pressure-applying portion 38f so long as there is sufficient area for applying finger pressure and no harm is done to the overall aesthetic sensation of the broach 31, namely to the balance of the external appearance. In addition, it will suffice if the connecting portions of the lever 38 and pin 35 are joined by a technique such as brazing. Gold, silver, platinum, brass and the like are ideal as the material of the main body 32 and fastener 33. An attaching method according to the first embodiment will now be described. Figs. 6A through 6D are side views for describing a procedure for attaching the broach according to the first embodiment. First, the user pinches the ornamental portion 32b of the main body 32 and the fastener 33 using the thumb and index finger so as to urge the pressure-applying portion 38f of lever 38 upward in the direction indicated by arrow U3, whereby the tip 35a of the pin 35 is caused to separate from the pin accommodating portion 36 in the direction indicated by arrow D3 (Fig. 6A). While holding the broach 31 in the state shown in Fig. 6A, the user passes the distal end of the pin 35 through a garment 63 at a desired position thereof so that the tip 35a of the pin 35 penetrates the garment 63 on its inner side (Fig. 6B). When the tip 35a of the pin 35 has penetrated to the inner side of the garment 63, the user passes the tip 35a through the garment 63 again in reverse fashion so that the tip emerges from the outer side of the garment (Fig. 6C). When the user has thus finished passing the pin 35 through the garment 63, the user removes the U-direction pressing force acting upon the lever 38. When the pressing force is removed, the lever 38, namely the fastener 33, is restored to its initial state shown in Fig. 3 owing to the biasing force of the torsion coil spring 37 (Fig. 6D). In the manipulation of the broach 31 described in connection with Fig. 6D, the user need only remove the force that opens the distal end of the pin 35. In other words, the user need only remove the hand from the broach 35. Further, even if the garment 63 shifts toward the distal end of the pin 35 in the state shown in Fig. 6D, the curved portion 35b functions as a stopper so that movement of the garment 63 up to the tip 35a is prevented. In addition, since the projections provided on the side portions 36a, 36b of the pin accommodating portion 36 slide the garment 63, shifting of the garment can be held in check. As a result, in accordance with the first embodiment, the broach is capable of being held reliably in a state attached to a garment. Further, a single manipulation for opening the distal end of the pin 5 suffices, and no additional labor whatsoever is required with regard to the pin 35 after the pin is passed through the garment 63. As a consequence, the broach obtained is very simple to manipulate. In other words, the broach has improved operability. At the same time, since there are but few parts, construction is very simple and the broach can be manufactured at low cost. Furthermore, the fact that construction is very simple makes it possible to freely design the broach main body without detracting from the aesthetic sense of the external appearance of the broach and without affecting the construction of the fastener. Though a torsion coil spring is used as the spring in the first embodiment described above, the invention is not limited thereto, for a leaf spring also can be used. A modification of the first embodiment will now be described. 〈First Modification〉 Though the first modification is composed of parts similar to those of the first embodiment described above, the method of attaching the fastener and the method of manipulating the fastener differ. Fig. 7 is a side view illustrating the construction of a broach according to a first modification of the first embodiment, and Fig. 8 is an enlarged view of a principal portion showing an example of attaching the broach according to the first modification of the first embodiment. In Fig. 7, a broach 71 according to the first modification includes a main body 72 having ornamental portions 72a, 72b, and a fastener 73 axially supported on a connection portion 79 provided rearwardly of the fastener 72, similar to the broach 31 illustrated in Fig. 3. The first modification is similar to the first embodiment with regard to the construction in which a lever 78 is axially supported on the connection portion 79. The direction in which a tip 75a of a pin 75 joined to the lever 78 is biased is rearward in Fig. 7. With regard to the main body 72, a pin accommodating portion 76 which receives the tip 75a of the pin 75 is attached in such a manner that a bottom portion 76c is directed forwardly in Fig. 7. The manipulating procedure followed by the user is similar to that of the first embodiment described. The only difference is the rotating direction of the fastener 73 relative to the main body 72. In a case where a garment 81 shifts substantially up to the pin accommodating portion 76 via a curved portion 75b, as shown in Fig. 8, after the broach 71 has been attached, a downward pulling force or a moving force in the direction indicated by the arrow S acts upon the pin 75. However, in the state illustrated in Fig. 8, the construction in such that the direction in which the pin 75 is allowed to move, i.e, rotate, is limited solely to forward rotation in the drawing about the shaft (not shown) of the lever 78. Accordingly, the pin 75 does not rotate in the direction indicated by arrow D3', and the broach 71 can be maintained in the attached state as long as the user does not remove the broach 71 in accordance with the procedure. In the first modification, the rotational plane of the fastener 73 in the attached state is formed to be substantially parallel to the garment 81, and therefore the attached state can be maintained more reliably in comparison with the first embodiment. 〈Second Modification) Fig. 9 is an external perspective view illustrating the construction of a principal portion of a second modification of the first embodiment. The broach of the second modification has a fastener different from that of the first embodiment. As shown in Fig. 9, a fastener 93 of the second modification has a lever 98, the cross section of which is U-shaped, similar to that of the first embodiment. The lever 98 has a bottom portion 98e to the distal end 98f of which is joined a U-shaped parallel pin 95 by means of a brazing process. Each pin of the parallel pin 95 has a curved portion 95c, 95d near the tip 95a, 95b, just as in the first embodiment. Fig. 9 illustrates only the fastener 93. However, in a case where the broach of the second modification is actually constructed, a shaft (not shown) is passed through holes 98b, 98d respectively provided in side portions 98a, 98c of the lever 98, and the fastener is provided on the main body (not shown) so as to be axially supported, just as in the first embodiment. Thus, in the second modification, the broach is fastened to the garment at two locations by using the parallel pin 95 having the two parallel pins. As a result, stability when the broach is attached is improved in comparison with the case where fastening is achieved at one location, as in the first embodiment. Though the parallel pin is composed of two pins in the second modification described above, the present invention is not limited thereto, for three or more pins can be used if the arrangement is within the scope of the invention. In addition, it is permissible to construct the fastener not by adopting an integrated structure for the parallel pins but by preparing pins corresponding to the number of pins to be set and joining these pins to the lever one at a time in parallel relation. 〈Third Modification〉 Fig. 10 is an external perspective view illustrating the construction of a principal portion of a third modification of the first embodiment. In the third modification, a parallel pin 105 having a shape similar to that of the second modification is used, as illustrated in Fig. 10. A fastener 103 of the third modification has an arrangement in which a folded portion 105a of the parallel pin 105 is exposed from the rear end of a lever 108 having a construction from which the pressure-applying portion is deleted. This pressure-applying portion is formed by the exposed portion. The third modification also is attached by a manipulation method similar to that of the second modification. 〈Fourth Modification〉 The fourth modification has, as a structural element, a fastener having a parallel pin, as in the second and third modifications. Fig. 11 is a bottom view illustrating the construction of a principal portion of a fourth modification of the first embodiment, and Fig. 12 is a bottom view for describing an example of attaching the fourth modification of the first embodiment. A parallel pin 115, which is a part of the fastener, has curved portions similar to those of the second and third modifications, as well as curved portions 115c, 115d symmetrically forming a widened portion and a narrowed portion in directions opposing the two pins. The widened portion formed by the curved portions 115c, 115d is set to have a distance (ℓ 2 in Fig. 11) at least greater than a distance (ℓ 1 in Fig. 11) between tips 115a, 115b. When the user actually passes the parallel pin 115 having the foregoing characterizing feature through a garment to attach the broach, the portions where the parallel pin 115 intersects the dashed lines I1, I2 in Fig. 12 are the portions where the garment is pierced. In the fourth modification, a projection 120a is provided for limiting the positions between the pins when a pin accommodating portion 120 receives the parallel pin 114. The width of the projection 120a is indicated by ℓ 3 in the direction opposing the two pins. The relationship among ℓ 1 , ℓ 2 , ℓ 3 is as follows: ℓ 2 /2 - ℓ 1 /2 = ℓ 1 /2 - ℓ 3 /2 The distance between the holes when the parallel pin 115 is passed through the garment is substantially decided by the tips 115a, 115b. Accordingly, even if the garment attempts to move toward the tips of the parallel pin 115 from the state shown in Fig. 12, by way of example, the distance between the tips 115a, 115b can only be narrowed to the minimum value ℓ 3 because of the relationship expressed by Eq. (1) above. This prevents movement of the garment because the pin width having the maximum distance ℓ 2 between the pins cannot be made to attain the distance ℓ 1 . Thus, in accordance with the fourth modification, the effect of preventing displacement of the garment, namely the effect of preventing the broach from readily slipping off while being worn, is added to the effects of the second and third modifications. In the fourth modification described above, the curved portions in the directions opposing the two pins form widened portions, at two locations, that are larger than the widened portion at the tips of the pins. However, the present invention is not limited to this arrangement, for widened portions can be provided at one location or at three or more locations in conformity with the axial length of the parallel pin set depending upon the size, etc., of the broach. 〈Fifth through Ninth Modifications〉 Fifth through ninth modifications in which the shape of the pin of the first embodiment is modified will now be described. Fig. 13 is a side view showing a principal portion of a fifth modification in which a pin of the first embodiment is modified; Fig. 14 is a side view showing a principal portion of a sixth modification in which a pin of the first embodiment is modified; Fig. 15 is a side view showing a principal portion of a seventh modification in which a pin of the first embodiment is modified; Fig. 16 is a side view showing a principal portion of a eighth modification in which a pin of the first embodiment is modified; Fig. 17A is a side view showing a principal portion of a ninth modification in which a pin of the first embodiment is modified; and Fig. 17B is a side sectional view showing a cross section taken along line C-C' of the pin illustrated in Fig. 17A. First, according to the fifth modification shown in Fig. 13, a portion of the main body of a pin 135 is provided with a projection 135b protruding toward the side of the main body, not shown. The amount of protrusion of the projection 135b is set to be approximately equal to a difference in level, in the axial direction, of the pin main body, which has a tip 135b. Accordingly, when the broach according to the fifth modification is attached, displacement of the garment, not illustrated, can be limited by clamping the garment between the projection 135b and the broach main body, or by situating the garment on the side of the lever (not shown), with the projection 135b serving as a boundary. Next, according to the sixth modification shown in Fig. 14, the main body of a pin 145 is provided with curved portions 148b, 148c which describe arcs in a direction facing away from the broach main body. In accordance with this structure having the two curved portions 148a, 148b, a function such as that of a shortener can be added to surpass the function of a broach passed through a garment. More specifically, in a case where this arrangement is used as a shortener employed to correct an irregularity in two strings of pearls of a necklace of pearls or the like, it will suffice to insert the threads connecting the pearls in each of the spaces formed between the curved portions 148a, 148b and the broach main body. This manipulation can be carried out in simple fashion using one hand. The sixth modification is capable of providing the effects of a broach similar to those of the fifth modification. In the sixth modification, only one of the curved portions 148a, 148b can be provided so that the fastener can be employed as an open clip, by way of example. In this case, it will suffice to pass a broach whose pin end is opened between pearls of a pearl necklace, and attach the broach in such a manner that the thread connecting the pearls is inserted. In the seventh modification shown in Fig. 15, the outer peripheral surface of a pin 155 is provided with a plurality of projections 155a. In the eighth modification shown in Fig. 16, the outer peripheral surface of a pin 165 is provided with a plurality of recesses 165a. In the ninth modification shown in Figs. 17A and 17B, use is made of a pin 175 having a twisted structure in which the cross section has the shape of an octagon. The shapes of the pins of the seventh, eighth and ninth modifications function to increase the frictional force relative to the sliding garment. Accordingly, in the seventh, eighth and ninth modifications, the broach can be prevented from simply falling off the garment. 〈Tenth through Twelfth Modifications) Tenth through twelfth modifications will now be described, in which the construction of the pressure-applying portion of the lever of the first embodiment is modified. Fig. 18 is a side sectional view showing a principal portion of a tenth modification in which a lever of the first embodiment is modified; Fig. 19 is a side sectional view showing a principal portion of an 11th modification in which a lever of the first embodiment is modified; and Fig. 20 is a side sectional view showing a principal portion of a 12th modification in which a lever of the first embodiment is modified. First, in the tenth modification shown in Fig. 18, the rear end of a lever 188, namely a pressure-applying portion 189, has a shape bent downwardly at an angle . In the 11th modification shown in Fig. 19, the rear end of a lever 198 is provided with a pressure-applying portion 199 on a concave surface. In the 12th modification shown in Fig. 20, the rear end of a lever 208 is provided with a pressure-applying portion 209 in which a plurality of grooves are arrayed in a direction which crosses the longitudinal direction of the lever 208. It is permissible also to array these grooves in a direction longitudinal of the lever 208. Thus, according to the tenth modification, 11th modification and 12th modification, the ease with which the finger contacts the lever and the engagement of the finger with the lever are improved, as a result of which excellent operability can be obtained when the broach is attached and detached. In addition, by improving the engagement of the finger, the pin can be opened and closed without inconvenience even when the broach (fastener) is small in size. 〈13th Modification〉 Fig. 21 is a side view showing the construction of a principal portion of a 13th modification of the first embodiment. The 13th modification is an example in which the construction of the pin accommodating portion of the first embodiment is modified. As shown in Fig. 21, a pin accommodating portion 216 which receives a tip 215a of a pin 215 has a sharp projection 216a protruding rearwardly from at least one side portion 216b, namely in the direction of the lever, not shown. In the 13th embodiment, if the garment shifts and moves up to the pin accommodating portion 216 after the broach is attached to the garment, the projection 216a will pierce the garment without harming the body of the wearer, thereby making it possible to check any further movement of the garment toward the side of the pin accommodating portion 216. The modifications of the first embodiment described above can be used singly or in combination. [Second Embodiment] In the first embodiment and its modifications described above, the pin accommodating portion is strictly an immovable element for receiving the tip of the pin. However, this does not impose a limitation upon the present invention, for an arrangement can be adopted in which the cover follows up the operation wherein the pin is received within the pin accommodating portion, thereby covering the pin tip so that it will not be exposed to the outside. As in the first embodiment, the second embodiment comprises a main body having one or more ornamental portions, and a fastener axially supported on a connection portion of the main body, though these elements are not shown. Fig. 22 is a side sectional view showing the construction of a principal portion of the second embodiment of the present invention. With regard to the principal portion of the broach according to the second embodiment illustrated in Fig. 22, a main body 242 is formed to have a recess 242a slanting forwardly (to the left in the drawing) from the position of the connection portion (not shown) up to a predetermined position, and a pin accommodating portion 246 according to the second embodiment is attached at the forward end (the left end in the drawing) of the recess 242a so as to be concealed from view. The recess 242a has a depth approximately equivalent to an axially directed difference in level between the main body of a pin 245 and a pin tip 245a. The pin accommodating portion 246 has a construction possessing two opposing tongue-shaped side portions, and a follower 247, which has an F-shaped cross section, freely rotatably supported by a shaft 248 spanning the distal ends of the two side portions. With regard to the follower 247 shown in Fig. 24, an upper plate urged upwardly by the pin 245 defines a pin receiving plate 247a which receives the tip 245a of the pin 245 when the broach is in an initial state prior to being attached and when the broach is in the attached state. Further, a plate provided substantially in parallel with the pin receiving plate 247a defines a covering plate 247b which covers the tip 245a of the pin 245 received by the pin receiving plate 247a when the broach is in an initial state prior to being attached and when the broach is in the attached state. A connecting plate 247d which connects the parallel pin receiving plate 247a and covering plate 247b is penetrated by a shaft 248 at a position where the shaft intersects the covering plate 247b. The follower 247 has a stopper 247c projecting from the position penetrated by the shaft 248 and directed along an extension line from the connecting plate 247d. The material constituting the follower 247 can be the same as that of the main body and fastener described above. The operation of the principal portion of the second embodiment will now be described in accordance with the manipulation procedure. Figs. 23A through 23E are side views for describing a procedure for attaching the broach according to the second embodiment. First, starting from the initial state shown in Fig. 22, the user manipulates the lever (not shown) to rotate the pin 245 in the direction indicated by arrow D4, as shown in Fig. 23A. As a result of this operation, the tip 245a of pin 245 separates from the pin receiving plate 247a of the follower 247, abuts against the side face of the covering plate 247b and causes the follower 247 to rotate about shaft 248 in the direction indicated by arrow R2, i.e., to follow up the motion of the pin. When the operation for moving the tip 245a of pin 245 to a position at which it is completely freed from the accommodated state has been performed (Fig. 23B), the user passes the tip 245a through a garment 251 (Fig. 23C) just as in the first embodiment. When the pin 245 has separated from the follower 247, the latter is capable of turning freely. However, if the follower 247 is rotated in the direction of arrow R2, the stopper 247c is received by a stopper receiving portion 242b provided on the wall portion of the main body 242 adjacent the pin accommodating portion 246. As a result, rotation of the follower 247 in the R2 direction is limited. With regard to the positional relationship between this limit position and the position at which the pin is freed, an angle is set that allows some rotation of the follower 247. Next, the user sets the freely rotatable follower 247 at the above-mentioned limit position and removes the force applied to the lever (not shown). As a result of this operation, the pin 245, which has been passed through the garment 251, rotates in the direction indicated by arrow U4 in accordance with the operation that restores the fastener to its original state. Owing to such rotation, the tip 245a first abuts against and forces upward the distal end 247d of the pin receiving plate 247a so that the pin receiving plate 247a, namely the follower 247, is rotated in the direction indicated by arrow R3 (Fig. 23D). Furthermore, the pin 245 rotates to attain its initial state shown in Fig. 22, so that the broach of the second embodiment is attached to the garment 251, as depicted in Fig. 23E. In accordance with the second embodiment described above, substantially the entirety of the pin is accommodated within the main body. As a result, the broach can be affixed to the garment more closely in comparison with the affixed state of the first embodiment, and therefore tilting of the entire broach about the fastener portion as an axis can be eliminated. In addition, accommodating substantially the entire pin within the main body makes it possible to enhance safety. Of course, the effects obtained with the first embodiment can be obtained with the second embodiment as well. The modifications of the first embodiment described above can be applied to the second embodiment singly or in plural. Though the present invention has been described in the foregoing embodiments by taking a broach as a typical example of an ornamental device, the invention can also be adapted to an open clip attached to a pearl necklace, a shortener attached to two strings of pearls of a pearl necklace, a tie pin or a pin used in setting hair. In case of an ornamental device set directly on the human body, such as in the hair, the tip should not be sharpened more than necessary. The present invention is not limited to the above-described embodiments but can be modified in various ways within the scope of the claims.
