Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an accessory put on a human
earlobe, etc.
[0003] 2. Description of the Related Art
[0004] Conventionally, accessories such as pierced earrings are
configured by joining an accessory core part (such as a needle) to
a basic accessory part, and a portion of the accessory core part,
which penetrates into a wearing target (such as an earlobe), is
held by a catch in normal cases. Here, holding by a normal catch is
made to prevent the accessory core part from falling out of the
wearing target.
[0005] For the above described accessory, the following accessory
is disclosed, for example, by Patent Document 1 (Japanese Examined
Utility Model Application Publication No. HEI7-6809). This
accessory is configured by providing a basic accessory part having
a diameter larger than that of the accessory core part at one end
of the accessory core part, and a stop part also having a diameter
larger than that of the accessory core part at the other end, and
by omitting a catch.
[Patent Document 1] Examined Utility Model Application Publication
(???) No. HEI7-6809
[0006] Incidentally, the accessory according to the above described
Patent Document 1 is fixed to a wearing target with the stop part
having a diameter larger than the accessory core part. However,
since also the stop part once penetrates into the wearing target,
it sometimes falls out of an earlobe. If the diameter of the stop
part is made larger than the accessory core part in order to
prevent this fall, there arises a problem such that the wearing
target is injured, or the pierced earring does not become stable in
the wearing target.
[0007] Additionally, since the stop part has a protruding
configuration, for example, the neck of a person positioned in the
rear of the wearing target is injured in some cases. Even if
attempts are made to provide a member which covers the stop part in
order to overcome this problem, the stop part must be configured to
have a diameter further larger than the insertion core part, and
this is difficult.
SUMMARY OF THE INVENTION
[0008] It is an object of the present invention is to provide an
accessory which prevents a fall, and enhances safety with a simple
configuration in consideration of the above described conventional
problems.
[0009] To overcome the above described problems, the accessory
according to the present invention comprises a basic accessory
part, an insertion part that is joined to the basic accessory part
and inserted into a penetration hole provided in a wearing target,
and a catch for holding a portion of the insertion part, which
penetrates into the penetration hole. The insertion part comprises
an insertion core part one end of which is joined to the basic
accessory part, and a stop part which is formed at the other end of
the insertion core part and has a diameter larger than the
insertion core part on a plane orthogonal to the longitudinal
direction of the insertion core part. The catch is made of an
elastic material, and is configured to have an insertion hole part
corresponding to the shapes of the stop part and the insertion core
part extending from the stop part by a predetermined length.
[0010] With the above described configuration, the insertion hole
part corresponding to the shapes of the stop part and the insertion
core part extending from the stop part by the predetermined length
are comprised, and the stop part is fixed to the catch made of an
elastic material, whereby the stop part is easy to be inserted into
the catch and difficult to fall. Accordingly, with the simple
configuration, the accessory is prevented from falling out of a
wearing target, and the stop part is prevented from injuring the
neck of a person, an object, etc. positioned in the rear of the
wearing target.
[0011] Preferably, the stop part is configured to be almost
spherical or almost semispherical.
[0012] Preferably, the stop part is configured to be almost
ellipsoidal or almost semi-ellipsoidal.
[0013] Preferably, the elastic material is silicone rubber.
[0014] With the accessory according to the present invention, the
insertion hole part corresponding to the shapes of the stop part
and the insertion core part extending from the stop part by the
predetermined length are comprised, and the stop part is fixed to
the catch made of an elastic material, whereby the stop part is
easy to be inserted into the catch and difficult to fall.
Accordingly, the accessory is prevented from falling out of a
wearing target, and the stop part is prevented from injuring the
neck of a person, an object, etc. positioned in the rear of the
wearing target with the simple configuration. Therefore, with the
accessory according to the present invention, a fall can be

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] An accessory according to a preferred embodiment of the
present invention is hereinafter described with reference to the
drawings.
[0022] FIG. 1 is a cross-sectional view showing the accessory
according to one preferred embodiment of the present invention.
[0023] In this figure, the accessory 1 comprises a basic accessory
part 2, an insertion part 3, and a catch 4. This accessory 1 is
inserted into a penetration hole 5a provided in a wearing target 5.
The basic accessory part 2 is an accessory portion, which is
positioned on the front side of the wearing target 5, namely,
positioned in a portion that is most visible in the accessory
1.
[0024] The insertion part 3 comprises an insertion core part 3a and
a stop part 3b. One end of the insertion core part 3a is joined to
the basic accessory part 2, for example, by being formed as a
single-piece or by being welded. In contrast, the stop part 3b,
which has a diameter L2 larger than the diameter L1 of the
insertion core part 3a on a plane orthogonal to the longitudinal
direction A of the insertion core part 3a, is provided at the other
end of the insertion core part 3a. The stop part 3b here is
spherical in shape.
[0025] The catch 4 is made of an elastic material (such as silicone
rubber), and an insertion hole part 4a, which corresponds to the
shapes of the stop part 3b and the insertion core part 3a extending
from the stop part 3b by a predetermined length, namely, which has
the same shapes, is open. This insertion hole part 4a is open to an
extent not to penetrate into the catch 4 in order to prevent the
stop part 3b from touching the neck of a person, etc. positioned in
the rear of the wearing target. In the state shown in FIG. 1, the
insertion part 3 (the stop part 3b and a portion of the insertion
core part 3a) is already inserted into the insertion hole part 4a,
and fits neatly. Here, the catch 4 is made of an elastic material.
Therefore, even if the stop part 3b having the larger diameter
(diameter L2) is inserted into the portion (diameter L1) of the
insertion hole part 4a, which corresponds to the insertion core
part 3a, the insertion hole part 4a once expands and restores to
the original shape.
[0026] If the wearing target 5 is a human earlobe, the insertion
part 3 having a diameter larger than the diameter L3 of the
penetration hole 5a shown in FIG. 1 can be penetrated without being
damaged. Therefore, it is desirable to make the diameter L2 of the
stop part 3b slightly larger than the diameter L3 of the
penetration hole 5a.
[0027] Additionally, if the diameter L1 of the insertion core part
3a is equal to or smaller than 2 mm, it is desirable to multiply
the diameter L2 of the stop part 3b by 1.05 to 2.00 times of the
diameter L1 of the insertion core part 3a, preferably, 1.2 to 1.8
times, and, more preferably, 1.5 to 1.7 times. Here, if the above
proportions are applied when the diameter L1 is more than 2 mm,
this causes a problem such that a difference between the diameter
L2 of the stop part 3b and the diameter L1 of the insertion core
part 3a increases, and the insertion core part 3a does not become
stable in the penetration hole 5a of the wearing target 5.
Accordingly, it is desirable to make the above described
proportions lower when the diameter L1 is more than 2 mm.
[0028] As described above, the accessory 1 according to this
preferred embodiment has a configuration where the insertion core
part 4a, which corresponds to the shapes of the stop part 3b and
the insertion core part 3a extending from the stop part 3b by a
predetermined length, is comprised, and the stop part 3b is fixed
to the catch 4 made of an elastic material, whereby the stop part 3
is easy to be inserted into the catch 4 and difficult to fall.
Accordingly, the accessory 1 is prevented from falling out of the
wearing target 5, and the stop part 3b is prevented from injuring
the neck of a person, an object, etc. positioned in the rear of the
wearing target 5 with the simple configuration. Therefore, with the
accessory 1 according to this preferred embodiment, its fall can be
prevented and safety can be enhanced with the simple
configuration.
[0029] Additionally, the stop part 3b is configured to be spherical
in shape, whereby the stop part 3b is easy to be inserted into the
insertion hole part 4a of the catch 4, and the insertion hole part
4a is difficult to be destroyed. Accordingly, the catch 4 can be
used without daily trouble.
[0030] FIG. 2A is a cross-sectional view showing the insertion part
and the catch according to the above described preferred
embodiment. FIGS. 2B to 2D are cross-sectional views showing
insertion parts and catches according to modification examples of
the above described preferred embodiment.
[0031] The insertion part 3 and the catch 4, which are shown in
FIG. 2A, are the same as those shown in FIG. 1. Namely, the stop
part 3b of the insertion part 3 is spherical in shape. In contrast,
a stop part 13b of an insertion part 13, which is shown in FIG. 2B,
is semispherical in shape. In this case, the stop part 13b can be
further prevented from falling out of a catch 14.
[0032] Additionally, a stop part 23b of an insertion part 23, which
is shown in FIG. 2C, is ellipsoidal in shape. This stop part 23b is
ellipsoidal in shape extending on a plane orthogonal to the
longitudinal direction A of an insertion core part 23a.
Furthermore, a stop part 33b shown in FIG. 2D is semi-ellipsoidal
in shape. Also in this case, the stop part 33b is semi-ellipsoidal
in shape extending on a plane orthogonal to the longitudinal
direction A of an insertion core part 33a. Also with these stop
parts 23b and 33b, which are ellipsoidal and semi-ellipsoidal, the
accessory 1 is further prevented from falling out of catches 24 and
34.
