Description
BACKGROUND
[0001] Field of Invention
[0002] The disclosure relates to a lens exchanging structure. More
particularly, the disclosure relates to a lens exchanging structure
that can stably install lenses onto a spectacle frame and
conveniently exchange the assembled lenses.
[0003] Description of Related Art
[0004] At present, when the lenses of the existing spectacle
structures need to be exchanged, a special screwdriver is needed to
loosen the screws to open the side openings of the spectacle
frames. Then, the lenses can be removed. Since the screws are very
small, and thus can be easily dropped and lost if assembling and
removing the lenses is not performed carefully. Moreover, the
threads are very fine, and thus the threads directly applied by a
screwdriver can be easily damaged or broken by the improper
application of force. Therefore, it is quite inconvenient to
assemble or remove lenses, especially for elders. In addition,
glasses are an important accessory of people's dresses. People need
to wear glasses with suitable style and color to match the costumes
thereof according to different attended activities. Since it is not
easy to change the lenses of the existing spectacles, consumers
need to buy several spectacles and thus it costs much to become an
economic burden of the consumers.
SUMMARY
[0005] This invention is related to a lenses exchanging structure.
When the lenses of the provided lenses exchanging structure need to
be exchanged, only the fixing parts of the main spectacle frame is
fiddled to separate the fixing parts and the positioning slots of
the lenses frames. Then, the lenses frames can be removed from the
original spectacle frame and then assembled with another main
spectacle frame having other styles and colors. Therefore, the
effect of conveniently exchanging lenses can be achieved.

intercalating trenches 122 of the lens-frame assembling parts 12
each has an intercalating concave part 123 concavely disposed on
one side near the center of the glasses frame 11. The two inner
sides of the glasses frame 11 respectively have a sliding slot 13,
and one end of each sliding slot 13 extends to the adjacent
lens-frame assembling part 12. Two through holes 14 are
respectively disposed on the two front sides of the glasses frame
11, and the through holes 14 are communicated with the sliding
slots 13. The sliding slots 13 are extended to form connecting
slots 15, and the connecting slots 15 are extended to the lateral
sides of the glasses frame 11. Locking holes 16 are penetratingly
disposed on the two sides of the glasses frame 11 from top to
bottom, and the locking holes 16 penetrate the connecting slots 15.
Fixing parts 17 are respectively disposed in the sliding slots 13
on two lateral sides of the glasses frame 11. A positioning bump
171 is protrudingly disposed on one end of each fixing part 17, and
the positioning bumps 171 are adjacent to the lens-frame assembling
parts 12. A toggle sheet 172 is formed on the front side of each
fixing part 17, and the toggle sheets 172 are located outside the
through holes 14. A long slot hole 173 is disposed to vertically
penetrate the top and bottom ends of each fixing part 17. An
elastic part 174, such as a spring, is disposed in the long slot
hole 173. The two sides of the glasses frame 11 are respectively
installed by a temple 18. Front terminals of the temples 18 have
connecting sections 181 for connecting the connecting slots 15.
Receiving parts 182 are disposed in the center of the connecting
sections 181 of the temples 18 to correspond to the sliding slots
13 of the glasses frame 11, and thus the fixing parts 17 can
movably slide toward the receiving parts 182 of the temples 18.
Locking holes 183 vertically penetrate the connecting sections 181
of the temples 18 to correspond to the locking holes 16 of the
glasses frame 11. Two locking parts 19, such as bolts, are disposed
to respectively penetrate the locking holes 16 on two sides of the
glasses frame 11, the long slot holes 173 of the fixing parts 17,
and the locking holes 183 of the temples 18, so that the temples 18
and the glasses frame 11 are pivotally connected. One ends of the
elastic parts 174 in the long slot holes 173 of the fixing parts 17
are against the adjacent ends of the positioning bumps 171. The
other ends of the elastic parts 174 are positioned to be against
the locking parts 19 penetrating the long slot holes 173 of the
fixing parts 17.
[0014] Two lens frames 2 are installed on the lens-frame assembling
part 12 of the glasses frame 11 of the main spectacle frame 1 from
the bottom openings 121 of the lens-frame assembling part 12. Two
lens assembling holes 21 are respectively disposed on the two lens
frame 2 for installing optical lens. An intercalating bump 22 is
located on one is side of each lens frame 2 to correspondingly
intercalate with the intercalating trench 122 of each lens-frame
assembling parts 12. A positioning slot 23 is located on the other
side of each lens frame 2 to correspond to the position of the
sliding slots 13 on two sides of the glasses frame 11. The fixing
parts 17 assembled with the two sliding slots 13 are protruded to
reach the positioning bumps 171 of the two lens-frame assembling
part 12 to respectively against the positioning slots 23 of the two
lens frames 2 for insertion and positioning.
[0015] Accordingly, the parts above are all assembled. Please refer
to FIG. 4. A user uses his or her hand to fiddle the toggle sheets
172 of the fixing parts 17 to move the fixing parts 17 toward the
direction of the temples 18 and then slide to the temples 18. At
this time, one ends near the positioning bumps 171 of the fixing
parts 17 escape from the lens-frame assembling parts 12 of the
glasses frame 11. The elastic parts 174 between the end near the
long slot holes 173 of the fixing parts 17 and the locking parts 19
are compressed.
[0016] Subsequently, please refer to FIG. 5, the user can assemble
the lens frames 2 having optical lens with the two lens-frame
assembling parts 12 of the glasses frame 11 of the main spectacle
frame 1 sequentially. That is, the intercalating flanges 22
disposed on one sides of the lens frames 2 are intercalated into
the intercalating concave parts 123 of the lens-frame assembling
parts 12 of the glasses frame 11, and then the edges of the lens
frames 2 are intercalated into the intercalating trenches 122 of
the lens-frame assembling parts 12. The positioning slots 23 on the
other side of the lens frames 2 are positioned to correspond to the
positions of the sliding slots 13 of the glasses frame 11.
[0017] Next, please also refer to FIG. 6. The user can release the
fiddling of the fixing part 17. At the same time, the compressed
elastic parts 174 in the long slot holes 173 of the fixing parts 17
can restored to their original shape to return the positions of the
fixing parts 17. Meanwhile, the ends near the positioning bumps 171
of the fixing parts 17 extend to the sites of the lens-frame
assembling parts 12, so that the positioning bumps 17 of the fixing
parts 17 can insert into the positioning slots 23 on lateral sides
of the lens frames 2 to stably install the lens frames 2 onto the
lens-frame assembling parts 12 of the glasses frame 11.
[0018] Therefore, the eyesight of the user can go through the lens
installed on the lens frames 2 assembled onto the main spectacle
frame 1 to prevent the damage from UV or splashing foreign matters
according to the lens category installed in the lens frame 2.
Furthermore, when the user wants to wear different costumes and
choose a main spectacle frame 1 of a suitable style and color
according to the attended activity, the lens frames 2 can be
removed from the main spectacle frame 1. When the lens frames 2
need to be removed, the user can fiddle the toggle sheets 172 of
the fixing parts 172 to make the fixing parts 17 slide is toward
the direction of the temples 18, and one ends near the positioning
bumps 171 of the fixing parts 17 leave the lens-frame assembling
parts 12 of the glasses frame 11 to be separated from the
positioning slots 23 of the lens frames 2. At this time, the user
can remove the lens frames 2 from the lens-frame assembling parts
12 of the glasses frame 11 of the original main spectacle frame 1,
and the lens frames 2 can be reinstalled onto another main
spectacle frame 1 with a needed style and color. Accordingly, no
tools are needed during the lenses exchanging process, and the lens
frames 2 can be conveniently assembled on various main spectacle
frames 1. Therefore, a user only needs to buy main spectacle frames
1 with various styles and colors to change the appearance of the
spectacle for matching the costumes. In addition, a user also can
buy different lens frames 2 with lenses of different functions,
such as optical lenses, UV lenses or eye-protecting lenses. Then,
the user can choose proper lenses according to the purposes of
going outside, such as constructing works or outdoor activities, to
replace the lens frames 2 with different lenses having different
functions to save lots of cost for buying various glasses.
