Description
TECHNICAL FIELD
[0001] The present invention relates to an improvement on an
attachment mechanism through which glass lenses, sunglass lenses,
or the like are attached to a cap or sun visor. Further, the
present invention more particularly relates to an attachment
mechanism through which polarized glass lenses can be freely
rotated between a flip up position at which the polarized glass
lenses are flipped up and an eyepiece position at which the
polarized glass lenses are allowed to be close to eyes, and to clip
sunglass lenses for a cap or sun visor in which a rotation angle
position can be adjusted gradually between both positions and in
which positioning can be performed simply and reliably at an
optimum position.
BACKGROUND ART
[0002] Clip sunglass lenses in which a clip is clipped on a brim of
a cap or sun visor so that polarized glass lenses are attached
thereto have been known. Such sunglass lenses can be used easily
since the polarized glass lenses can be disposed in front of eyes
without employing temples and/or nose pads, whereby they win
popularity among constant users of sunglasses.
[0003] With respect to such clip sunglass lenses, clip sunglass
lenses in which polarized glass lenses are rotated between an
eyepiece position at which they are close to the eyes of a user and
a flip up position at which they are flipped up to a brim side so
that they can be held at the respective positions have been
proposed. (For example, see Japanese Utility Model Application
Laid-Open No. 04-27419. (see p. 1, FIGS. 1and 2))
[0004] However, in the clip sunglass lenses disclosed in this
reference, the polarized glass lenses can only be rotated simply
between the eyepiece position and the flip up position, and there
is a problem that it is difficult to positionally adjust and hold
at a position at which the glass lenses are close to the eyes of a
user and to position and hold the glass lenses at an arbitrary
rotation angle position between the eyepiece position and the flip
up position.
[0005] Further, in these types of clip sunglass lenses, there is a
drawback that the polarized glass lenses are not interchangeable in
accordance with the purpose of use and weather since the polarized
glass lenses cannot be detached therefrom.
[0006] The present invention has been made in consideration of the
existence of the problem in conventional clip sunglass lenses as
described above, and it is an object of the present invention to
provide clip sunglass lenses for a cap or sun visor in which a
holding angle of the polarized glass lenses can be adjusted step by
step between the eyepiece position and the flip up position and in
which positioning can be performed simply and reliably at an
optimum position.
[0007] It is another object of the present invention to provide
clip sunglass lenses in which the polarized glass lenses are
interchangeable in accordance with the purpose of use and
weather.

BEST MODE FOR CARRYING OUT THE INVENTION
[0020] An embodiment of the present invention will be described
below further in detail with reference to the drawings which
illustrate the embodiment specifically.
[0021] The embodiment according to the present invention will be
described with reference to FIGS. 1 to 8.
[0022] The present invention is sunglass lenses which are coupled
with a brim B of a cap, sun visor, or the like in a clip manner so
that oblong polarized glass lenses 4 can be arranged in front of
the eyes of a user (see FIG. 1).
[0023] In the drawing, reference numeral 1 denotes a clip, and this
clip 1 which has a side surface roughly U-shaped. By allowing this
clip 1 to pinch the brim B of a cap, sun visor, or the like, the
entire sunglass lenses can be coupled with the brim B.
[0024] Provided are a holding mouth 11 into which the brim B is
inserted by pressure so that the holding mouth 11 is coupled with
this brim B and a socket mouth 12 disposed in a lower side of the
holding mouth 11, and notches 12a, 12a, . . . having a required
interval are formed inside this socket mouth 12 along an
extraction/insertion direction.
[0025] Reference numeral 2 denotes an insertion member. This
insertion member 2 has a plug portion 21 on its one end which can
be freely inserted into or pulled out of the socket mouth 12 of the
clip 1. A projection 21a which corresponds to the notches 12a of
the socket mouth 12 of the clip 1 is formed on this plug portion
21. This projection 21a is engageable with the notches 12a of the
socket mouth 12 (see FIG. 2).
[0026] At this time, as the need arises, by allowing a periphery of
the projection 21a to be notched into a lying U-shape, the
projection 21a is allowed to be vertically elastically movable so
that a sliding operation in forward and rearward directions can be
performed smoothly (see FIG. 3).
[0027] A fork-shaped clasping bracket 22 is integrally formed with
an end which is opposite to the plug portion 21 of the insertion
member 2. Connection holes 22a, 22a . . . having internal tooth
notches 22b, 22b, . . . on the inner circumferential surfaces
thereof are formed symmetrically in the respective clasping bracket
22 (see FIG. 4).
[0028] Further, reference numeral 3 denotes a level adjusting
member 3 formed into a plate shape. This level adjusting member is
provided with a coupling shaft 31. This coupling shaft 31 is fitted
into the connection holes 22a, 22a of the clasping bracket 22 of
the insertion member 2 to make angle positions stable step by step
through the pitch of the internal tooth notches 22b. Thus, step
notches 31a, 31a, . . . having a required interval are formed on a
surface of the coupling shaft 31, and notch grooves 32, 32, . . .
are formed on a plate surface of the level adjusting member 3.
[0029] Furthermore, reference numeral 4 denotes oblong polarized
glass lenses. This oblong polarized glass lenses 4 are formed by
pasting a polarized film on an acrylic plate and is formed into a
size by which both right and left eyes can be covered.
[0030] Reference numeral 5 denotes a level adjusting buckle. This
level adjusting buckle 5 is a sleeve member which is fixed on a
central portion of the oblong polarized glass lenses 4. An inner
circumferential surface of the level adjusting buckle 5 has hooking
projections 51 which are fitted into the notch grooves 32, 32, . .
. of the level adjusting member 3 so that position adjustment can
be freely performed.
[0031] In fabrication of the sunglass lenses of the present
embodiment, when the coupling shaft 31 of the level adjusting
member 3 is fitted into the connection holes 22a of the clasping
bracket 22, the step notches 31a formed on the outer
circumferential surface of the coupling shaft 31 engage the
internal tooth notches 22b formed on the inner circumferential
surfaces of the connection holes 22a, so that the level adjusting
portion 3 is coupled with the insertion member 2 such that the
level adjusting portion 3 is vertically swingable step by step (see
FIG. 5).
[0032] In this connection, by making the insertion member 2 and the
level adjusting member 3 from a synthesis resin (e.g., a polyamide
resin) whose surface friction coefficient is low and which has
excellent smoothness properties, a notch style engagement between
the projections 31a and the internal tooth notches 22b formed on
the inner circumferential surfaces of the connection holes 22a can
be smoothly performed (see FIG. 6).
[0033] The distal end of the lower end of the level adjusting
member 3 is branched into two so that both legs thereof can be
compressed elastically. Engaging claws 33 are protruded outwardly
on the distal ends, and when both legs of the lower end are
inserted into the level adjusting buckle 5, the engaging claws 33
securely engage a buckle edge portion 52 so that slipping off can
be prevented. Meanwhile, by pinching and pressing both legs of the
lower ends from both side surfaces, the engaging claws 33 can be
released from the engagement so as to be removed therefrom.
[0034] At this time, similarly to the above-described insertion
member 2, as the need arises, by allowing a periphery of the
hooking projection 51 in the level adjusting buckle 5 to be notched
into a lying U-shape, the hooking projection 51 is allowed to be
vertically elastically movable so that the oblong polarized glass
lenses 4 can be slid vertically smoothly.
[0035] In the present embodiment, the distal end of the lower end
of the level adjusting member 3 is branched into two, and the
engaging claws 33 are protruded outwardly on the distal ends, so
that the engaging claws 33 securely engage the buckle edge portion
52 to allow slipping off to be prevented when these lower ends are
inserted into the level adjusting buckle 5. By pinching and
pressing these lower ends from both side surfaces, engagement of
the engaging claws 33 can be released, whereby the oblong polarized
glass lenses 4 can be taken off (see FIG. 7).
[0036] The present embodiment fabricated in the above-described
manner can be simply attached to the brim B of a cap, sun visor, or
the like (see FIG. 8).
[0037] In the clip sunglass lenses of the present embodiment, the
clip 1, insertion member 2, level adjusting member 3, oblong
polarized glass lenses 4, and level adjusting buckle 5 can be
formed from a polyamide resin, whereby having elasticity and a high
wear resistance, being easily molded, and being excellent regarding
the cost.
[0038] Although the present invention is fabricated roughly as
described above, the present invention is not limited to the
above-described embodiment, and various changes may be made within
the principle and scope of "CLAIMS", and for example, even if
combinations in fitting relationships of respective members
(protrusions and recesses such as of projections and holes) are
replaced oppositely, definitely similar effects can be
obtained.
[0039] In the oblong polarized glass lenses 4, an upper end portion
thereof may be bent to be formed so as to match the shape of the
brim B, and an outer side portion may be bent to be formed in an
eyepiece direction to enhance light shading properties. Further, a
material employed in the present invention is not limited to a
polyamide resin, and the clip sunglass lenses may be made from a
synthesis resin such as polyacetal resin, polycarbonate resin,
polyester resin, or the like, and any of them belongs to the
technical scope of the present invention.
[0040] As described using the embodiment, since the clip sunglass
lenses obtained by adopting the present invention is fabricated in
such a way that the step notches of the coupling shaft of the level
adjusting member engage the internal tooth notches formed on the
inner circumferential surfaces of the connection holes, the
polarized glass lenses can be held precisely not only at an
eyepiece position and a flip up position but also at positions in
front of the eyes of a clip-sunglass-wearing user, and they can
securely placed at a certain angle position.
[0041] Since the clip sunglass lenses according to the present
invention are fabricated in such a way that the projection of the
plug portion engages the notch formed on the socket mouth of the
holding mouth, the insertion member can be secured so as to be
slidable in the forward and rearward directions. Further,
similarly; since they are fabricated in such a way that the hooking
projections of the level adjusting buckle engage the notch grooves
formed on the level adjusting member, the level adjusting buckle
can be slid vertically to be secured.
[0042] Therefore, the oblong polarized glass lenses are attachable
and detachable and can be interchanged in accordance with the
purpose of use and weather. Further, since the polarized glass
lenses can be positioned at an optimum position simply and
reliably, it is very handy, and practical utility value is very
high.
Industrial Applicability
[0043] The present invention can be adopted in all kinds and
features of caps or sun visors as long as glass lenses or sunglass
lenses can be attached to them.
