SWIMMING GOGGLES
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
[0001] The present invention relates to swimming goggles, and
particularly to swimming goggles which have a left frame, a right frame, a
nose bridge and pad that integrally formed by different material or of the
same material with different rigidity.
2. RELATED ART
[0002] Swimming goggles are generally divided into two types: separate
type and integral type. The separate type has a separate connecting member
connecting a left frame and a right frame together; the integral type has a
left
frame and a right frame integrally formed with a connecting member. Lenses
of the integral type have to be fixed on the left and the right frames. If the
material is too soft, the left and right frames may be deformed by pulling
force when being worn, and the lenses can not be fixed with retention. So
the material is restrained in rigidity. Pads of the integral type are formed
on
the left and right frames and are not flexible relatively, therefore touching
users' faces uncomfortably.
[0003] Moreover, the connecting member, which is used to connect the
left and the right frames, is made of excessive hard material. The connecting
member can not meet consumers with different face profiles, and even can
not touch their faces fitly, resulting in water leakage.
SUMMARY OF THE INVENTION
[0004] Accordingly, an object of the present invention is to provide
swimming goggles which make users feel comfortable and prevent from
i

leakage.
[0005] The swimming goggles comprise an integral left and right frames
and nose bridge, lenses received in the left and right frames, pads and a head
strap. The integral left and right frames and nose bridge include an outer
frame and an inner frame. The outer frame comprises front sections of the
left and right frames and the nose bridge. The inner frame comprises rear
sections of the left and right frames and the nose bridge. The pads are made
of soft material and are assembled on the rear sections of the left and right
frames. The head strap is assembled on the outer frame.
[0006] The outer frame and the inner frame are made of different
material or of the same material with different rigidity.
[0007] The hard outer frame bears pulling force from the head strap when
being worn, minimizing influence on the lenses. The soft nose bridge has
appropriate flexibility. The pads are soft enough to provide comfortable
feeling for users, and to match users with different face profiles, preventing
from leakage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Referring to Fig. 1, swimming goggles 1 in accordance with the
present invention comprise an integral left and right frames and nose bridge
2, lenses 3, pads 6 and a head strap (not shown). The integral left and right
frames and nose bridge 2 comprise an outer frame 20 and an inner frame 21
which may be made of different material or of the same material with
different rigidity. In this embodiment, the outer frame 20 and the inner frame
21 are made from Thermoplastic Rubber (TPR) with different plastic
characteristics of molding, shaping and gluing. The outer frame 20 and the
inner frame 21 match with different colors for achieving colorful look. The
outer frame 20 comprises front sections of the left and right frames 201, 202
and a front section of the nose bridge 203. Assembling portions 204 are
formed on outward sides of the front sections of the left and right frames
201, 202 and along outer rims of the front sections of the left and right
frames 201, 202. Through holes 205 are defined in the assembling portions
204 for threading the head strap therethrough. The inner frame 21 comprises
rear sections of the left and right frames 211, 212 and a rear section of the
nose bridge 213. The pads 6 are made of the same material as the inner
frame 20, and the material of the pads 6 has lower rigidity compared to the
inner frame 20. Notably, in practice, the front sections of the left and right
frames 201, 202 and the nose bridge 203, and the rear sections of the left and
right frames 211, 212 are made of material with a certain rigidity against
pulling force when being worn. The pads 6 are made of soft material. The
rear section of the nose bridge 213 is made of material softer than the front
3
CA 02635156 2008-06-17
section of the nose bridge 203 and harder than the pads 6. Alternatively, the
front sections of the left and right frames 201, 202 and the front section of
the nose bridge 203 are made of material with a certain rigidity against
pulling force when being worn. The rear sections of the left and right frames
211, 212 and the rear section of the nose bridge 213 are made of material
softer than the front section of the nose bridge 203 and harder than the pads
6.
[0017] The lenses 3 are made from Polycarbonate (PC), and have flanges
30 along rims thereof. The flanges 30 are unitarily enveloped by the outer
frame 20 and the inner frame 21 when injection shaping.
[0018] With reference to Figs. 2 through 4, when the outer frame 20 and
the inner frame 21 are shaped by injection, the flanges 30 of the lenses 3 are
enveloped by and are glued with the outer frame 20 and the inner frame 21.
The head strap extends through the through holes 205. The front sections of
the left and right frames 201, 202 and the front section of the nose bridge
203 are rigid enough to resist from pulling force when being worn, and the
assembling portions 204 are made of relatively hard material. Thus the front
sections of the left and right frames 201, 202 are not affected when being
worn. The rear section of the nose bridge 213 is made of relative soft
material such that possesses appropriate flexibility to fit for users with
different face profiles and prevents from leakage. The pads 6 are made of
soft material thereby providing comfortable feeling for users.
[0019] Fig. 5 illustrates a second embodiment of the present invention.
Similar to the first embodiment, the swimming goggles 1' of the second
embodiment comprise an integral left and right frames and nose bridge 2',
lenses 3' and pads 6'. The integral left and right frames and nose bridge 2'
comprise an outer frame 20' and an inner frame 21'. The outer frame 20'
comprises front sections of the left and right frames 201', 202' and a front
4
CA 02635156 2008-06-17
section of the nose bridge 203'. Assembling portions 204' are formed on
outward sides of the front sections of the left and right frames 201', 202'
and
along outer rims of the front sections of the left and right frames 201',
202'.
The inner frame 21' comprises rear sections of the left and right frames 211',
212' and a rear section of the nose bridge 213'. The pads 6' are integrally
formed with the rear sections of the left and right frames 211', 212'. The
difference between the second embodiment and the first embodiment
focuses on the material. The outer frame 20' and the inner frame 21' are
made of the same material Silicon Rubber and are of different colors. The
material Silicon Rubber is soft and is difficult to glue to dissimilar
material.
In the second embodiment, hard clamp frames 4' are provided for clamping
the front sections of the left and right frames 201', 202'. The outer frame
20',
the inner frame 21' and the pads 6' are injection shaped like the first
embodiment. In assembly, as shown in Fig. 6, the outer frame 20' and the
inner frame 21' are injection shaped, and then in cooperation with the clamp
frames 4', as shown in Fig. 7, retain the lenses 3' . The lenses 3' are made
of
Cellulose Acetate (AC).
[0020] Further referring to Figs. 8 and 9, anchors 40' are respectively
disposed on joint points of the clamp frames 4' with the front section of the
nose bridge 203', the rear section of the nose bridge 213', the front sections
of the left and right frames 201', 202', and the rear sections of the left and
right frames 211', 212'. The anchors 40' form steps in respect to the clamp
frames 4', and lock with inner edges of the front sections and the rear
sections of the left frames and the right frames 201', 202', 211', 212'.
Embedding grooves 431', 432' are respectively defined in joint portions of
the front sections and rear sections of the left frames and the right frames
201', 202', 211', 212' with the front section and rear section of the nose
bridge 203', 213' for receiving the anchors 40'. The front sections of the
left
frames and the right frames 201', 202' form assembling ridges 41' along
CA 02635156 2008-06-17
peripherals thereof adjacent the lenses 3'. The clamp frames 4', together
with the anchors 40', lock with the inner edges of the front sections and rear
sections of the left frames and the right frames 201', 202', 211', 212'. Thus
the lenses 3' are continuously enclosed by the assembling ridges 41' and the
clamp frames 4'. Each clamp frame 4' forms at least a pair of locking arms
42'. Locking grooves 433', 434' are respectively defined in the front
sections and rear sections of the left frames and the right frames 201', 202',
211', 212' and lock with the locking arms 42' for fixing the lenses 3'. A head
strap 5' connects with outward sides of the clamp frames 4'.
[0021] The front sections of left and right frames 201', 202' and the front
section of the nose bridge 203' are rigid enough to resist from pulling force
when being worn, and the assembling portions 204' are made of relatively
hard material. Thus the front sections of the left and right frames 201', 202'
are not affected when being worn. The rear section of the nose bridge 213' is
made of relative soft material such that possesses appropriate flexibility to
fit for users with different face profiles and prevents from leakage. The pads
6' are made of soft material for providing comfortable feeling for users.
[0022] It is understood that the invention may be embodied in other
forms without departing from the spirit thereof. Thus, the present examples
and embodiments are to be considered in all respects as illustrative and not
restrictive, and the invention is not to be limited to the details given
herein.
