Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a tension locking goods for
earring, more particularly, a tension locking goods for earring
useful for removably attaching the earring to an earlobe,
comprising a plate spring having an embossed projection at one
side, wherein the plate spring is constructed and assembled to
allow the embossed projection to be hooked and supported by two
fixing pieces in a movable manner when the fixing pieces formed on
both ends of the tension locking goods are bent and supported in a
fixed position so that it can protect the plate spring from being
detached or released and, at the same time, to inhibit or reduce
local stress load on the plate spring generated by repeatedly using
the tension locking goods to essentially prevent partial cutting of
the plate spring, and obtain tension effect for the tension locking
goods even by slight force, thereby, accomplishing smooth and
enhanced wearing sense.
[0003] 2. Description of the Related Art
[0004] It is well known that there are two kinds of earrings
including one to be put on an earlobe without a hole and the other
for the earlobe with a hole to wear the earring. Particularly, such
earring has a tension locking goods possible to attach and detach
the earring to the earlobe.
[0005] FIGS. 4 and 5 in the accompanying drawings illustrate
conventional tension locking goods for the earring.
[0006] As shown in FIGS. 4 and 5, the tension locking goods 20
comprises a main body 22 of the locking goods which includes a
fixing hole 27 integrated at one end to be hooked by a fixed end 16
of an earring body 10 while, on the other end thereof, a hinge hole
25a being formed through spring guidance walls 25 bent inside of
the main body 22 and opposited each other; and a plate spring 30
endowing tension effect to the tension locking goods 20 between the
spring guidance walls 25, wherein the plate spring 30 has one end
fixed by two fixing pieces 23 formed by bending both sides of the
main body 22 of the locking goods and two supporting pieces 24.
[0007] Such constructed tension locking goods 20 in prior art has
the plate spring 30 mounted inside the main body 22 to press and
fix the plate spring 30 by only fixing piece 23 of a part
constructing a fixed support, and the supporting pieces 24 being
apart from the plate spring 30 and supported at a desirable space.
Accordingly, by repeatedly applying tension force of the plate
spring 30, fatigue stress is locally generated in the vicinity of
the fixing piece 23 as the fixed support.
[0008] Tension effect of such plate spring 30 starts at the fixing
piece 23 as the fixed support during initial working for widening
the tension locking goods 20, then, progresses on the supporting
piece 24 as a starting point to intend distribution of the fatigue
stress, however, it was found that the supporting piece 24
represented no remarkable effect. In addition, since such
conventional tension locking goods 20 was under the fatigue caused
by the tension effect of the plate spring 30 repeatedly applied,
the goods 20 was locally cut nearby the fixing piece 23 as the
fixing support. Also, the goods rather had less force for fixing
the plate spring 30 since only the fixing piece 23 had a role of
press-fixing the goods 20, and exposed a problem not to vary or
increase the tension effect of the tension locking goods 20 by
means of the plate spring 30.
[0009] Such problem may reduce tension effect due to fatigue
limitation of the plate spring 30 as it repeatedly conducts
detaching/attaching movement (that is, rotational motion) of the
tension locking goods 20, whereby it may cause lowering putting-on
sense of the earring 1 to lead to a trouble that the earring 1 put
on the earlobe comes loose and, thereby, being released from the
earlobe.
SUMMARY OF THE INVENTION
[0010] Therefore, the present invention is purposed to solve the
above captioned problems and has an object to provide a tension
locking goods for earring useful for detachably wearing the
earring, comprising a plate spring having an embossed projection at
one side, wherein the plate spring is constructed and assembled to
allow the embossed projection to be hooked and supported by two
fixing pieces in a movable manner when the fixing pieces formed on
both ends of the tension locking goods are bent and supported in a
fixed position so that it can protect the plate spring from being
detached or released and, at the same time, to inhibit or reduce
local stress load on the plate spring generated by repeatedly using
the tension locking goods to essentially prevent partial cutting of
the plate spring, and obtain tension effect for the tension locking
goods even by slight force, thereby, accomplishing smooth and
enhanced wearing sense.
[0011] To achieve the above object of the present invention, the
present invention will be described in detail with reference to the

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] The present invention will be described in more detail by
reference to the above drawings which are presented for purposes of
illustration but should not be construed to limit the scope of the
invention thereto.
[0020] FIG. 1 is a perspective view of an earring coupled with a
tension locking goods according to the present invention. FIG. 2 is
a partially enlarged cross-sectional view of a body part of the
earring and the tension locking goods of the present invention
assembled together. FIG. 3(a) is a development status view of a
body of the tension locking goods according to the present
invention developed before the body is coupled with the plate
spring; and FIG. 3(b) is a cross-sectional view of the plate spring
according to the present invention. Hereinafter, parts of the
tension locking goods substantially identical to those of the
conventional locking goods are illustrated with the same
numerals.
[0021] As illustrated in FIGS. 1 and 2, an earring 1 comprising a
tension locking goods 20 rotatably coupled with a body part 10 of
the earring by a hinge 12 and expressing tension effect by a plate
spring 30, wherein the plate spring is coupled at a desirable
position of inner side of a locking body 22 formed with two fixing
pieces 23 having semicircular space parts 23a at both sides of the
locking body and has an embossed projection 32 at one side, which
is constructed and assembled to allow the embossed projection 32 to
be hooked and supported by the fixing pieces 23 in a movable manner
when the fixing pieces 23 formed on both ends of the tension
locking goods 20 are bent and supported in a fixed position.
[0022] Such fixing pieces 23 are shown in FIG. 3(a) illustrating
the pieces in a development status before bending the pieces into
the locking body 22. The fixing pieces 23 formed with the
semicircular spaces 23a at both sides of the locking body 22 are
faced to each other to form an entirely circular hook space 26 to
be fitted with the embossed projection 32 when a bending process is
conducted to joint the locking body 22 and the plate spring 30,
thereby forming an assembly of the locking body 22 and the plate
spring 30. In this case, the embossed projection 32 is fitted into
and couple to lightly move within the circular space 26 formed by
connecting two fixing pieces 23.
[0023] Such hooked and supported plate spring 30 is not secured by
a press-fixing process commonly applied to conventional plate
springs, but assembled by the embossed projection 32 fitted into
the hook space 26 formed by the fixing pieces to lightly move
within the space 26. The embossed projection 32 freely moves or
flows within the circular space 26 formed by bending the fixing
pieces 23 and is hooked and supported whenever tension is applied
to the plate spring 30 due to movement of the earring body part 10,
whereby it allows the plate spring 30 not to be detached nor
released from the locking body during its use.
[0024] The present invention constructed as illustrated in FIGS. 1
and 2, the earring 1 is attached to an earlobe by pulling the
tension locking goods 20 outside to be widen around the hinge 12 in
the earring body part 10 (see an imaginary line in FIG. 2), then,
pushing the tension locking goods 20 to a fixed end 16 to return
the tension locking goods 20 through tension recovery action of the
plate spring 30 to allow the fixed end 16 to be fitted into a
fixing hole 27 formed at one side of the locking body 22.
[0025] Herein, the tension recovery action of the plate spring 30
is more efficient than of conventional springs.
[0026] Briefly, if the tension locking goods 20 is pulled outside
to be widen around the hinge 12 on the earring body part 10, the
tension recovery action of the plate spring 30 in an initial
widening motion process is generated on the fixing pieces 23 and,
in turn, the tension supporting piece 14 of the earring body part
10 supports the other end of the plate spring 30 to crease a small
bending (that is, the tension recovery action) on the plate spring
30, thereby being dismissed from its orginal position. At this
time, the embossed projection 32 formed at one side of the plate
spring 30 can do a littly free sliding-reciprocation within the
hook space 26 made by the fixing pieces 23, whereby the plate
spring 30 is not under fatigue stress caused by the tension
recovery action in any local parts, rather receives the tension
recovery action over entire portion of the plate spring 30 and
provide a dispersion effect evenly dispersing the fatigue stress
without excessive load to any specified parts, whereby it prevents
partial cutting of the fixing pieces 23 as the fixed support due to
the fatigue stress caused by the tension recovery action of the
plate spring 30 repeatedly applied like as in conventional springs,
to result in accomplishing noticeable improvement of reliability
for earring products.
[0027] In addition, the present invention has advantages of
protecting the plate spring 30 from being cut out in partial and
increasing tension recovery action, thereby making it possible to
be substituted for common low quality of plate springs.
[0028] As clear from the above description, the present invention
provides a tension locking goods for earring useful for removably
attaching the earring to the earlobe, comprising a plate spring
having an embossed projection at one side, wherein the plate spring
is constructed and assembled to allow the embossed projection to be
hooked and supported by the fixing pieces in a movable manner to
protect the plate spring from being detached or released and, at
the same time, to inhibit or reduce local stress load on the plate
spring generated by repeatedly using the tension locking goods to
essentially inhibit partial cutting of the plate spring, and obtain
tension effect for the tension locking goods even by slight force,
thereby, accomplishing smooth and enhanced wearing sense.
[0029] It is further understood by those skilled in the art that
the forgoing description is a preferred embodiment and that various
changes and modifications may be made in the invention without
departing from the spirit and scope thereof.
