Title
Swimming goggles
Field of the Invention
The subject invention relates to a type of swimming goggles, particularly to
one
with a nose bridge involving flexible frames and clasp pieces to combine left
and
right lens frames.
Bacl~ground of the Invention
There are different ways to join the lens frames of swimming goggles, which
can be grouped into two categories: one is a monobloc lens frame form,
protective
pads and the nose bridge, the other involves fastening the left and right lens
frames
using a nose bridge. The monobloc type of nose bridge is a simple type that
does
not allow adjustment. This nose bridge specification will suit the general
consumer
public. The fastening type allows multiple-step adjustment. The consumer can
make
proper adjustment to suit the span between the user's eyes. Both types have
their
market share, and their respective advantages and disadvantages in production.
Basically, therefore, the development and improvement of the monobloc type and
the
fastening type are designed separately. -
However, the monobloc type of swimming goggles that are easy to use without
the need for adjustment has become the mainstream in appeal and design. The
conventional monobloc type of swimming goggles is generally made from hard
resin
(polycarbonate resin), in which entire frame body is rigid without
flexibility, so it
only suits users with a specific face shape. As a result, another conventional
design
has been developed which uses soft resin to shape the lens frames, nose
bridge~and
protective pads as one monobloc. The nose bridge serves the concurrent
purposes of
joining the two frames and providing proper flexibility and avoiding
deformation of

CA 02314593 2000-07-26
the frame body due to the lens accommodation. This lens type cannot withstand
the
pulling force of the headband, and special consideration must be paid to the
construction of the swimming goggles, such as: reinforced strength design for
the
nose bridge, or reinforced strength against frame body deformation ; so tf~at
the
frame body will not be deformed.
Brief Description of the Invention
The objective of the subject invention is to provide a new swimming goggle
construction with an innovative design that can be conveniently assembled and
comfortably worn by the user. Said swimming goggles provide twin frames made
from a flexible material to join the frames. Thus, the twin frames can be
separately
considered in terms ofdesign and suitable material selection. Considerations
can he
taken to require the nose bridge to be equipped with adequate tensile
strength, to
provide a monobloc type exterior configuration and fastening assembly style .
The subject invention is characterized in that: the swimming goggles have a
binding frame that is used for the assembly of the main lens frame. The
binding
frame includes the left and right frame units and a nose bridge linking the
left and
right frame units. On the left and right frame units near the nose bridge is a
clasp unit.
On the main frame unit corresponding to the clasp unit is a clasp piece,
thereby
secures the main frame unit to the binding frame.
As mentioned in the above characteristics, the clasp i.lnit has clasp grooves
on
the left and right frame units corresponding to the nose bridge. The clasp
piece is
formed as a post on the main frame unit.
Another characteristic of the subject invention is that, on one side of the
left and
right frame units, away from the nose bridge, and between the main frame units
is an
assembling device. The assembling device includes assembling grooves on the
left
and right frame units. A check unit on the main frame unit corresponds to the
_2_

CA 02314593 2000-07-26
assembling groove with a joining unit in contact with the check unit. On the
joining
unit are headband positioning grooves to enable assembling the main frame unit
with the left and right frame units.
The assembling groove is an opening facing from outside to the inside of the
S left and right frames. The check unit is a clasp piece formed on the main
frame unit.
The joining unit refers to a first clasp arm and a second clasp arm forced on
one side
of a plate body and in contact with the clasp piece. On the plate surface are
several
grooves for the positioning of the headband.

Detailed Description of Preferred Embodiment
Please refer to Figs. I and 2, the subject swimming goggles invention 1 is
comprised of a binding frame 1 U, two lens frames 11 and 11', an assembling
device 2,
and a headband device 3. The binding frame 10 is made of a flexible material
involving a left and a right frame unit 101 and 102, serving to accommodate
the lens
frames 11 and 11' in a way that the lens 110 and 110' accommodate the lens
frames
l l and 11' match the left/right frame units 101 and 102. The left and right
frame
units 101 and 102 are joined by a nose bridge 103. On the nose bridge 103 is a
foam
sponge 4 to provide comfortable contact with the user's nose ridge. Near the
nose
bridge on the left and right frame units 101 and 102 are three clasping units,
-
respectively, elongated square grooves 104, 104' located on the nose bridge
103 and
elongated round grooves 105, 105' located on the top and bottom positions
ofthe left
and right frame units 101 and 102. Said lens frames 11 and 11' are made of
hard
polycarbonate resin material, assembled on the left and right frame units 101
and 102,
which accommodate the lens 110 and 110', and, corresponding to the three clasp
mortises 104 (elongated square groove) 105, 105' (elongated round grooves) are
clasp tenors, such as an elongated square tenor 112 to match the elongated
square
~ruuve 1 U4, and elongated round IL:IIUnS 1 13 to match the elongated round
grooves

CA 02314593 2000-07-26
105, 105'.
Furthermore, on the left/right frame units 101 and 102 and away from the nose
bridge 103 is the installation of an assembling device 2. Said assembling
device 2
includes an assembling hole 20 located on the left/right frame units 101 and
102. A
check unit 21 located on the lens frames I I and I 1 ' matching said
assembling hole 2,
and a joining unit 22 pulling through the assembling hole 20 to be engaged to
the
check unit 21. On the joining unit 22 is a positioning groove 23 to fix the
headband of
the swimming goggles. This construction is characterized by more solid
assembly of
the main frame unit with the left and right frame unit. The assembling hole 20
on the
left/right frame unit 101 and 102 is an opening facing obliquely from outside
toward
the inside. The check unit 21 forms a clasp jut with the lens frames I 1 and
11'. The
joining unit 22 involves a first clasp arm 221 and a second clasp arm 222
formed on
one side of a plate body to catch the clasp jut (check unit 21 ), and on the
plate surface
are several positioning grooves 23 to fasten the headband device 3.
Please refer to Figs. 3, 4 and 5, which explain how one side of the lens frame
is
assembled. As shown in the drawing, firstly, the lens frame I 1 is slightly
inclined, so
that its elongated square tenon can be clasped inside the elongated square
groove 104
of the frame unit 101. The lens frame 1 I is depressed so the elongated round
tenon
113 is fastened with the elongated round groove 105, now the lens frame 11 is -
primarily set in place. Secondly, the assembling device 2 is inclined and
inserted into
the assembling hole 20, so the first clasp arm 221 is in contact with one end
of the
clasp jut (check unit 21), which is further depressed so that the second clasp
arm 222
is linked to the other end of the clasp jut (check unit 21 ), thus the
assembling device
2 is depressed and secured with the lens frame 11. One point worth mentioning
is
that, the installation of the plate-shaped assembling device 2 serves to
complement
the assembling hole 20 with an opening, so the appearance of the swimming
goggles
can be enhanced. The assembling device 2 provides additional positioning
effect to

The above description has proved that the subject invention is able to achicvc
its objective to satisfy the requirements for a patent right. However, the
above
description covers merely a preferred embodiment of the subject invention. All
equivalent modifications and variations deriving from the above description
shall be
