SWIMMING GOGGLES
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
[0001] The present invention relates to swimming goggles, and more
particularly to swimming goggles which have easily-adjustable head fasteners.
2. RELATED ART
[0002] It is inconvenient to adjust head fasteners of conventional swimming
goggles during use. Conventional swimming goggles provide adjusting buttons
for
positioning and adjusting the head fasteners. Each adjusting button defines a
pair
of holes through which the head fasteners are pulled for positioning. During
use the
head fasteners cannot be adjusted, so the swimming goggles have to be taken
off
to adjust the head fasteners. Moreover, the head fasteners are difficult to
adjust to
a desired position.
[0003] Water leakage is another problem for the conventional swimming
goggles. Inner sides of the frames of the conventional swimming goggles are
subject to a connecting portion located between the frames leading to unclosed
joint
of pads of the swimming goggles and a concave between eyes and a nose, which
results in water leakage. It is hard especially for customers with high nose
bridges
to overcome this problem.

SUMMARY OF THE INVENTION
[0004] An object of the present invention is to provide swimming goggles
which are easily adjusted and perform optimally when worn and are
incrementally
adjustable.
[0005] Another object of the present invention is to provide swimming
goggles which closely contact a concave located between a nose and eyes
thereby
avoiding water leakage.
[0006] The swimming goggles comprise adjusting apparatuses between a left
and a right frames and head fasteners. Each adjusting apparatus comprises a
button
with a biasing arm for unilaterally engaging/disengaging a stopping slot of a
head
fastener, whereas a user can directly pull the head fasteners to make the head
fasteners tighter or press the button to make the head fasteners looser.
[0007] A connecting frame connects the left and the right frames of the
swimming goggles together. The connecting frame forms a pair of hoops
surrounding outer edges of the swimming goggles, and a nose support extending
inwardly from the hoops. The nose support is spaced a distance away from the
inner sides of the hoops, whereby the inner sides of the hoops are rotatable
in a
range of a certain degree.
[0008] The nose support of the connecting frame is enveloped by soft
material for comfortable touch feeling.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] With reference to FIGS. 1 and 2, the swimming goggles 1 include a
left frame 2, a right frame 3, adjusting apparatuses 4, a connecting frame 5
and
head fasteners 6 (shown in FIGS. 3 and 4). The left and the right frames 2, 3
respectively have outer surfaces 20, 30 and inner surfaces 21, 31. Receiving
passages 22, 32 are respectively located between the outer surfaces 20, 30 and
the
inner surfaces 21, 31 for accommodating lenses 9. The inner surfaces 21, 31 of
the
left and the right frames 2, 3, respectively have soft pads 8 to provide
comfortable
touch for the user. In combination to FIG. 6A, embedding holes 23, 33 are
3

CA 02433729 2007-05-28
-
respectively located between the left and right frames 2, 3 and proximate the
soft
pads 8 for receiving the connecting frame 5. Assembled holes 24, 34 are
respectively located in outer sides of the left and right frames 2, 3 for
receiving the
adjusting apparatuses 4. Camber springs 25, 35 respectively project from outer
sides of the left and the right frames 2, 3 and on lower edges of the
assembling
holes 24, 34 for providing return force while being pressed radially, as shown
in
FIGS. 6B and 6C.
[0016] The adjusting apparatuses 4 are respectively assembled to the
assembled holes 24, 34 of the left and the right frames 2, 3. FIG. 1 shows an
exploded view of an adjusting apparatus 4. Each adjusting apparatus 4 is made
of
hard material and includes a base 40 and a cover 41 integrated together, and a
button 42. The button 42 forms a biasing arm 43 and a shaft 44. The base 40
has
a shaft block 401, a shaft hole 402 being defined in the shaft block 401 for
mounting the shaft 44 thereon. A guiding bar 403 is provided adjacent to the
shaft
44 and includes a guide-in hole 404 and a guide-out hole 405 in opposite sides
thereof through which a head fastener 6 is pulled. Posts 406, 407 respectively
locate near the shaft blocks 401. In assembly the head fastener 6 is pulled
from the
guide-in hole 404, surrounding the guiding bar 403, and then out of the guide-
out
hole 405. The cover 41 forms a latch 410 to engage the base 40, and defines a
through hole 411 for receiving the button 42. In assembly the button 42
projects
slightly beyond the cover 41 for operation. The button 42 and the biasing arm
43
connect with the base 40 and cover 41 according to leverage principle. The
distance
between the button 42 and the center of shaft 44 is larger compared to the
distance
between the biasing arm 43 and the center of shaft 44. Thus, the shaft being
regarded as a center of the lever, the button 42 can be easily pressed to
actuate
relative movement of the stop arm 43. Referring to FIGS. 5, 6B and 6C, the
button
42 has a portion opposite to a pressed portion thereof and biasing against the
4

CA 02433729 2007-05-28
camber spring 25 of the left frame 2. The camber spring 25 is pressed and then
provides return force to push the button back. Further referring to FIG. 3,
the
button 42 presses a portion of the camber spring 25, which slantwise projects
beyond the cover 41 when assembly, whereby pressing force to the button is
controllable.
[0017] The connecting frame 5 is made of hard material and includes two
hoops 50, 51 and a nose support 52. The hoops 50, 51 are received in the
embedding holes 23, 33 of the left and the right frames 2, 3. The hoops 50, 51
respectively have joint blocks 53, 54 on outer sides thereof. Gaps 531, 541
are
respectively defined through the joint blocks 53, 54 and are substantially in
a
middle portion thereof. The joint portions 53, 54 are received in the
assembled
holes 24, 34 and engage with the adjusting apparatuses 4. The joint blocks 53,
54
respectively define positioning slots 532, 542 opposite to each other, and
posts 406,
307 are provided on the bases 40 for corresponding to the positioning slots
532,
542. Thus, the force on the head fasteners 6 is further exerted to the guiding
bar
403 and the jointing portion between the posts 406, 407 and the positioning
slots
532, 542 but not to the left and the right frames 2, 3, thereby preventing the
left
and the right frames 2, 3 made of soft material from distortion.
[0018] The nose support 52 extends inwardly from upper and lower edges
of the hoops 50, 51 and is located between the hoops 50, 51. The nose support
52
is further spaced a distance 55 away from inner sides of the hoops 50, 51,
allowing
free rotation of the inner sides of the hoops 50, 51 in a range of a certain
degree.
Additionally, the nose support 52 is enveloped by soft material 56 for
comfortable
touch feeling.

CA 02433729 2007-05-28
[0019] Also referring to FIG. 2, in assembly, the buttons 42 of the adjusting
apparatuses 4 project slightly slantwise beyond the covers 41. Further
referring to
FIG. 3, the biasing arms 43 abut against stopping slots 60 of the fasteners 6
at
accurate positions. Therefore in use, when the swimming goggles are worn, the
fasteners 6 are easily pulled from opposite sides of the left and the right
frames 2,
3 for precise positioning. As shown FIG. 4, when the buttons 42 are pressed
downward along a right arrow to make the head fasteners 6 looser, according to
leverage principle, the biasing arms 43 move upwardly to disengage from the
stopping slots 60. At that time the fasteners 6 can be adjusted appropriately.
When
the buttons 42 are released, the camber springs 25, 35 provide the buttons 42
with
return force such that the biasing arms 43 abut against the stopping slots 60.
[0020] The nose support 52 is spaced an appropriate distance away from the
left and right frames 2, 3, whereas inner sides of the left and the right
frames 2, 3
are rotatable freely to cooperate with concave between eyes and a nose of a
user
thereby overcoming the problem of water leakage and making more comfortable.
[0021] It is understood that the invention may be embodied in other forms
without departing from the spirt thereof. Thus, the present examples and
embodiments are to be considered as illustrative and not restrictive, and the
invention is not to be limited to the details given herein.
