Title
An innovated type o:f swimming goggles
[Field of the Invention]
This invention relates to a type of swimming goggles, particularly the one
that is
innovated and formed in a monobloc including a main unit of lens frame, a nose
bridge and a protective pad, wherein the protective pad serves to combine the
two
lenses in a same space of frame to provide wearing comfort, while the lenses
are
assembled firmly with thE; main unit of lens frame to prevent water seepage.
[Background of the invention]
As it is generally known, svvimming goggles can be used in swimming pools, for
snorkeling or scuba diving. For pool swimmers who need to regulate their
breathing
above water, swimming goggles must have a nose bridge to facilitate the
breathing.
For snorkelers or scuba divers who spend much more time in deep water,
swimming
goggles are made to cover their eyes and nose, to avoid water pressure causing
discomfort to the nose. t~onventional swimming goggles for pool swimmers have
two lens frames pressing; on the muscles around the eyes, but the installation
of a
protective pad may press the muscles around the eyes, the user may feel
discomfort,
or even water seeping inside due to muscle twitches caused by the discomfort.
[Objectives of the invention]
The major objective of this invention is to provide a type of swimming goggles
exclusively for swimming pool swimmers, involving a protective pad that serves
simultaneously as a facemask to provide a comfortable face contact, meanwhile,
the
two lens frames are combined in one space to enable a unique way of assembling
the
lenses with the lens frames, and provide convenient and firm assembling
effects.

[Characteristics of the invention]
The subject inv~tion of innovated swimming goggles is characterized by the
fact that: the lens frame main unit, the nose bridge and the protective pad
are formed
in a monobloc and made of a flexible material, and the said protective pad
involves a
single covering space; the two lenses made of a rigid material are joined by a
joint
part, wherein in the frame openings of the lens frame main units are inserted
grooves,
the edges are on the rim of the two lenses, so that the two lenses can be
assembled
and fitted into the lens frame main unit.
Another characteristic of the invention of innovated swimnning goggles is
that,
l0 between the frame openings of the lens frame main units is at least one
positioning
groove, on the joint part between the two lenses and opposite to the
positioning
groove is a stop unit, so designed that the two lenses and the lens frame main
units
can be assembled more firmly.
A fiuther characteristic of the invention is that, on the outside of the
longer axis
of the two lenses is a fixing device used to connect the headband, so that the
force
when the swinoming goggles are worn is resting on the two rigid lenses, to
ensure no
risk of water seeping through.
Yet another characteriistic of the invention lies in that, on the inserted
grooves on
two sides of the two lens ,frame main units and near the nose bridge is a
reinforcing
unit to reinforce the strength of its neighborhood area.

104 can
be assembled with the joint part 14 in connection with two lenses 13, 13' to
solidify
the assembly of the whole: unit (to be described later). On the frame openings
101,
101' and near the nose bridge 11 is installed a reinforcing unit 15 to
intensify the
-3-
CA 02314601 2000-07-26
strength of the frame openings 101, 101'. The protective pad 12 extends
outwardly
from the edge of the fi-ame openings 101, i01' of the main lens frame units
10, 10',
creating a height difference from the lens frame main unit and an excellent
flexibility,
and covering the upper and lower edges of the user's eyes (as shown in FIG.
