DESCRIPTION OF EMBODIMENTS
[0023] Now, ornaments according to embodiments of the present
invention are described with reference to the drawings.
First Embodiment
[0024] FIG. 1 is a sectional view illustrating a state in which an
ornament 1 according to a first embodiment of the present invention
is put on a wearing subject 5. FIG. 2 is a sectional view
illustrating a vicinity of a distal end of a post 3 illustrated in
FIG. 1. FIG. 3 is a sectional view of a stopper 4 illustrated in
FIG. 1 (without the post 3 to be attached thereto).
[0025] As illustrated in FIG. 1, the ornament 1 includes a
decorative body portion 2, specifically, the post 3 (insertion
portion) and the stopper (stopper body, that is, back piece) 4. The
ornament 1 is put on through a through-hole 5a formed through the
wearing subject 5.
[0026] The decorative body portion 2 serves as a decorative part
located on a front side of the wearing subject 5, that is, located
on a most visible part of the ornament 1. The wearing subject 5 is,
for example, an earlobe of a wearer.
[0027] As illustrated in FIG. 1, the post 3 has one end connected
to the decorative body portion 2 through, for example, integral
formation or welding.
[0028] As illustrated in FIG. 2, on another end side of the post 3,
along outer peripheries at first positions in a longitudinal
direction of the post 3, there are formed ring-shaped recess
portions (grooves) 21 each having a diameter smaller than those at
positions around the first position in the longitudinal direction.
In this embodiment, the ring-shaped recess portions 21 are formed
at two positions.
[0029] A shape of the post 3 illustrated in FIG. 2 is a general
shape widespread worldwide.
[0030] As illustrated in FIG. 3, the stopper 4 has an insertion
hole 4a capable of allowing the post 3 to be inserted thereinto by
a predetermined length of a region including the ring-shaped recess
portions 21. In the stopper 4, the insertion hole 4a is formed
through the stopper body.
[0031] Along inner peripheries at second positions in the insertion
hole 4a in an insertion direction of the post 3, there are formed
ring-shaped projection portions 41. The ring-shaped projection
portions 41 are configured to be fitted into the ring-shaped recess
portions 21 of the post 3 under a state in which the post 3 is
inserted into the insertion hole 4a. In this embodiment, the
ring-shaped projection portions 41 are formed at four positions in
the insertion hole 4a.
[0032] The stopper 4 is made of an elastic material (such as
silicone rubber).
[0033] Depending on a thickness of the wearing subject 5, an
insertion position of the post 3 in the insertion hole 4a is
determined.
[0034] When the wearing subject 5 is thick, a length of a part of
the post 3, which is located in the insertion hole 4a, is small.
Thus, the ring-shaped recess portions 21 of the post 3 are fitted
into ones of the ring-shaped projection portions 41, the ones being
closer to an opening portion 4a1 on an insertion side in the
stopper 4.
[0035] Meanwhile, when the wearing subject 5 is thin, the length of
the part of the post 3, which is located in the insertion hole 4a,
is large. Thus, the ring-shaped recess portions 21 of the post 3
are fitted into ones of the ring-shaped projection portions 41, the
ones being farther from the opening portion 4a1 on the insertion
side in the stopper 4.
[0036] Near the opening portion 4a1 on the insertion side in the
insertion hole 4a of the stopper 4, there is formed a guide surface
(tapered surface) 4b configured to guide the post 3 into the
opening portion 4a1. By virtue of the formation of such a guide
surface 4b, at the time of the insertion, the distal end of the
post 3 abuts against the guide surface 4b and is guided into the
opening portion 4a1. In this way, the post 3 can be easily inserted
into the insertion hole 4a of the stopper 4.
[0037] Further, by virtue of the formation of such a guide surface
4b, the post 3 can be inserted even when an inner diameter of the
insertion hole 4a is reduced. Thus, the post 3 can be more stably
held in the insertion hole 4a, and hence the post 3 can be
effectively restrained from dropping off the insertion hole 4a.
[0038] As illustrated, for example, in FIG. 1, the stopper 4 is
fixed to a decorative member 47 such as a pearl. A type of the
decorative member 47 is not particularly limited.
[0039] As illustrated in FIG. 1, the stopper 4 is fixed to the
decorative member 47 in a manner that the guide surface 4b is
located on an outside of the decorative member 47. With this, the
post 3 is easily inserted into the insertion hole 4a with use of
the guide surface 4b.
[0040] According to the configuration of the ornament 1, the post 3
is easily inserted into the stopper 4, and the post 3 is less
liable to drop off the stopper 4. With this simple configuration,
the ornament 1 can be prevented from dropping off the wearing
subject 5. Specifically, by virtue of the formation of the guide
surface 4b near the opening portion 4a1 of the stopper 4, at the
time of the insertion, the distal end of the post 3 abuts against
the guide surface 4b and is guided into the opening portion 4a1. In
this way, the post 3 can be easily inserted into the insertion hole
4a of the stopper 4. Further, by virtue of the formation of such a
guide surface 4b, the post 3 can be inserted even when the inner
diameter of the insertion hole 4a is reduced. Thus, a stability of
the post 3 held in the insertion hole 4a is increased. With this,
the post 3 can be effectively restrained from dropping off the
insertion hole 4a.
[0041] Further, according to the ornament 1, as illustrated in FIG.
2, the ring-shaped projection portions 41 in the insertion hole 4a
of the stopper 4 were formed in conformity with the general
widespread shape of the post 3.
[0042] With this, also when the stopper 4 is used in a large number
of general ornaments widespread worldwide, the post can be stably
held. As described above, according to the ornament 1, the post 3
can be prevented from dropping off the wearing subject, and can be
used for holding posts of other general widespread accessories.
[0043] Further, according to the ornament 1, the distal end of the
post 3 does not protrude to the rear of the wearing subject 5.
Thus, damage to the neck of a wearer, an object, or the like
located on the rear can be prevented.
[0044] In this way, with the simple configuration of the ornament
according to this embodiment, drop-off can be prevented, and safety
can be enhanced.
Second Embodiment
[0045] FIG. 4 is a sectional view of a stopper (stopper body) 104
of an ornament according to a second embodiment of the present
invention (without the post 3 to be attached thereto).
[0046] The stopper 104 is provided with an insertion hole 104a
capable of allowing a part of the post 3, which corresponds to a
predetermined length of a region including the ring-shaped recess
portions 21, to be inserted thereinto. The insertion hole 104a is
formed within the stopper body.
[0047] Along inner peripheries at second positions in the insertion
hole 104a in the insertion direction of the post 3, there are
formed ring-shaped projection portions 141. The ring-shaped
projection portions 141 are configured to be fitted into the
ring-shaped recess portions 21 of the post 3 under a state in which
the post 3 is inserted into the insertion hole 104a. In this
embodiment, the ring-shaped projection portions 141 are formed at
four positions in the insertion hole 104a.
[0048] The decorative member 47 is not fixed to the stopper 104
unlike, for example, the first embodiment. Thus, the stopper 104 is
used while being exposed to the outside.
[0049] Also according to this embodiment, advantages similar to
those of the first embodiment can be obtained.
[0050] Specifically, also in the stopper 104, a guide surface 104b
is formed near an opening portion 104a1. With this, at the time of
the insertion, the distal end of the post 3 abuts against the guide
surface 104b and is guided into the opening portion 104a1. In this
way, the post 3 can be easily inserted into the insertion hole 104a
of the stopper 104. Further, by virtue of the formation of such a
guide surface 104b, the post 3 can be inserted even when an inner
diameter of the insertion hole 104a is reduced. Thus, the post 3
can be more stably held in the insertion hole 104a, and hence the
post 3 can be effectively restrained from dropping off the
insertion hole 104a.
[0051] Further, according to this embodiment, the distal end of the
post 3 does not protrude to the rear of the wearing subject 5.
Thus, damage to the neck of a wearer, an object, or the like
located on the rear can be prevented.
[0052] In this way, with the simple configuration of the ornament
according to this embodiment, drop-off can be prevented, and safety
can be enhanced.
[0053] The present invention is not limited to the embodiments
described above.
[0054] Specifically, those skilled in the art may make various
modifications, combinations, sub-combinations, and alterations of
the components of the above-described embodiments within the
technical scope of the present invention or the equivalents
thereof.
[0055] More specifically, there may be employed, for example, a
stopper 204 having a shape illustrated in FIG. 5. The stopper 204
is provided with an insertion hole 204a formed through the stopper
204. The post 3 is inserted into the insertion hole 204a.
[0056] Further, as in the first embodiment, the stopper 204 is
provided with a guide surface 204b. In addition, ring-shaped
projection portions 241 are formed along an inner periphery of the
insertion hole 204a.
[0057] Still further, there may be employed, for example, a stopper
304 having a shape illustrated in FIG. 6. The stopper 304 is
provided with an insertion hole 304a formed through the stopper
304. The post 3 is inserted into the insertion hole 304a.
[0058] Further, as in the second embodiment, the stopper 304 is
provided with a guide surface 304b. In addition, ring-shaped
projection portions 341 are formed along an inner periphery of the
insertion hole 304a.
[0059] Yet further, for example, the number and the shape of the
ring-shaped grooves 21 of the post 3, and the numbers and the
shapes of the ring-shaped projection portions 41, 141, 241, and 341
of the stoppers 4, 104, 204, and 304 are not particularly limited
to those in the scope of the present invention, the scope being
specified in "Claims."
[0060] Yet further, in the cases exemplified in the embodiments
described above, heights of the ring-shaped projection portions 41,
141, 241, and 341 to be fitted into the ring-shaped recess portions
21 of the post 3 under the state in which the post 3 is inserted
into the insertion hole 4a, 104a, 204a, or 304a are set equal to
each other. However, for example, heights of ones of the
ring-shaped projection portions 41, 141, 241, and 341, which are
closer to the opening portion on the insertion side, may be set
larger.
INDUSTRIAL APPLICABILITY
[0061] The present invention is an ornament to be put, for example,
