DETACHABLE AND FIXED SUNGLASSES
TECHNICAL FIELD
The present invention relates to detachable and fixed sunglasses,
and more particularly to an eyeglass set comprising primary
eyeglasses and sunglass clip which can be detachably attached to the
primary eyeglasses which have rim-to-temple joint portions with
projecting sides having grooves or holes which receive clip arms on
both ends of the sunglass clip and have resilient fixing members ' for
securing the clip arms.
BACKGROUND ART
The typical prior art is eyeglass frames to which sunglasses are
attached by magnets(Korean Patent Application No. 10-1995-11855).
The eyeglass frames have magnets on its ends corresponding to both
clips of sunglasses, and the sunglasses are attached to the eyeglass
frames by magnetic force. In this design, sunglasses easily come off
from the eyeglass frames when a wearer moves violently or
excessively. At the present times when sunglasses are mostly used
during leisure activities, therefore, detachable sunglasses that can be
more firmly secured to eyeglass frames are required.
A further prior art is direct attachment of sunglass lenses to the
lenses of the primary eyeglasses (Korean Patent Application No.
20-1996-2026). Each sunglass lens has a hole in its each side, and a
bonding plate is inserted in each hole. The sunglass lenses are
attached to the lenses of the primary eyeglasses by such bonding
plates. This structure does not permit a wearer to see things clearly
since bonding plates exists between the primary eyeglass lenses and
sunglass lenses. It requires a wearer to touch sunglass lenses with
the hand to attach them to the primary eyeglass lenses, thus making
them being easily dirty.
DISCLOSURE OF IN INVENTION
The present invention makes up for the problems that the
conventional detachable sunglasses have.
The conventional detachable sunglasses easily come off from the
primary eyeglasses when an external impact is applied or when a
wearer moves violently or excessively. To solve such problems, the
prevent invention comprises the primary eyeglasses with
rim-to-temple joint portions 2 having receiving grooves a' or
receiving holes la containing fixing members b', and a sunglass clip
B having clip arms 11 which is inserted into the receiving grooves a'
or receiving holes la for securing the sunglass clip B to the primary
sunglasses A.
Therefore, the prevent invention can provide a wearer with
convenience since sunglasses do not easily come off from the primary
eyeglasses during leisure activities or violent exercises.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 illustrates an embodiment of the prevent invention
comprising primary eyeglasses A and a detachable and fixed sunglass clip B.
Referring to FIGS 2 and 3, a rim-to-temple joint portion 2
supporting a lens of the primary eyeglasses A has a forward
projecting side containing a receiving groove a' into which a clip arm
11 of a sunglass clip B is inserted. The receiving groove a' into
which the clip arm 11 of the sunglass clip B is inserted perpendicular
to the projecting side contains a clip arm fixing member b' . For the
conventional invention, rim-to-temple joint portions have magnets on
its outside, and a sunglass clip also has magnets on its clip arms.
Therefore, the sunglass clip is secured to the primary eyeglasses by
the force of magnets. This structure has a problem that the sunglass
clip easily comes off from the primary eyeglasses when an excessive
impact is applied or when a wearer moves violently. To secure the
sunglass clip arm 11 more firmly, the present invention has the
rim-to-temple joint portion which has a forward projecting side with
a receiving groove a' formed perpendicular to the projecting side. A
clip arm fixing member b', made of silicone or rubber that has
resilient force, is formed in the inside of the receiving groove a'. The
clip arm fixing member b' serves to secure the clip arm 11 by means
of its resilient force when the clip arm 11 is completely inserted into the receiving groove a'.
There are two methods of forming the clip arm fixing member b'
in the receiving groove a'. One is to bond the clip arm fixing member
b' to the inside of the groove a', using an strong adhesive, so that
the clip arm fixing member b' is not detached easily. The other is to
make a hole of a specific depth in the receiving groove a', and insert
and bond the clip arm fixing member b' into and to the hole. The
part of the clip arm fixing member b' which comes into direct contact
with the clip arm 11 may be formed in various shapes and sizes
according to resilient and securing forces of the clip arm fixing
member b' . For example, if the fixing member b' is formed small or
ovally, the securing force for the clip arm 11 is weak. Conversely, if
the fixing member b' is formed large or angularly, the securing force
for the clip arm 11 is strong.
The rim-to-temple joint portion 2 structured as described above
does not allow the connection of the primary eyeglasses A and the
sunglass clip B to be exposed to the outside, and prevents the
sunglass clip B from coming off from the primary eyeglasses when
an external impact is applied. The sunglass clip B is attached
downward to the primary eyeglasses B, thus completely preventing
the sunglass clip B from coming off from the primary eyeglasses
because of centrifugal force.
Referring to FIGS. 1 and 3, the sunglass clip B comprises sunglass
lenses, a support member and clip arm 11. As shown in FIG. 3, the
clip arm 11 is inserted downward and perpendicularly into the
receiving groove a' of the rim-to-temple joint portion 2, and secured
by the clip arm fixing member b' formed in the groove a'. The size
of the clip arm 11 is determined by considering the size and depth of
the receiving groove a' and the size and shape of the fixing member
b'. The clip arm 11 may be usually made of general materials for
eyeglass frames but in the prevent invention is made of rubber or
synthetic resin to maximize the frictional force between the clip arm
11 and the fixing member b' and to raise the securing force.
Referring to FIGS. 4 and 5 illustrate a receiving side hole la
formed in the rim-to-temple joint portion 2 and the state of the clip
arm 11 inserted into the receiving side hole la. The receiving side
hole la has a fixing member b' formed perpendicular to the direction
in which the clip arm is inserted into the receiving side hole la. The
clip arms 11 are inserted into the receiving side holes la in both
forward projecting sides of the rim-to-temple joint portions 2, using
the flexibility of the sunglass clip B. This method of inserting the
sunglass clip B gives an excellent securing force for the sunglass clip
B.
As described above, the present invention comprising the primary
eyeglasses A and the sunglass clip B is characterized by easy
attachment and detachment and strong securing force.
