ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an improved pad structure of swimming glasses and, more particularly, to a waterproof device worn when swimming to avoid discomfort of eyes.
BACKGROUND OF THE INVENTION
As shown in
FIGS. 1
to
3
, a pair of swimming glasses in the prior art comprise two lenses
50
made by extrusion of hard and transparent material. The adjacent sides of the two lenses
50
extend to form two lock rings
51
, and the left and right sides thereof also extend to form two lock rings
51
a,
respectively. A joining ring
52
is disposed between the two lenses
50
. The joining ring
52
can connect the two lock rings
51
so that the two lenses
50
can be joined together. A plurality of flanges
52
a
are disposed at inner sides of two ends of the joining ring
52
. The flanges
52
a
can be locked with the lock rings
51
to adjust the distance between the two lenses
50
. The two lock rings
51
a
at the left and right sides of the two lenses
50
are connected by a head band
53
. The inner side of the lens
50
forms a ring face
50
a.
The ring face
50
a
at the inner side of the lens
50
joins a pad
54
. A groove
54
a
is formed in the midst of the pad
54
. The outer edge of the groove
54
a
also has a ring face
55
.
Please also refer to
FIGS. 1
to
3
, when the swimming glasses are worn, the head band
53
of the swimming glasses is sleeved on the head and fixed, the two lenses
50
made by extrusion of hard and transparent material are then adjusted and fixed on the skins of eye sockets, and the ring faces
55
of the pads
54
contact tightly with the skins of eye sockets, thereby letting the swimming glasses achieve airtight effect.
However, when the swimming glasses are worn, it is necessary to pull the head band
53
to the head and fix it and let the ring faces
55
of the pads
54
contact tightly with the skins of eye sockets. For comfort of wearing, the pad
54
is made of soft material. Because the material of the groove
54
a
is also soft material, and the soft material near the eye socket is very thin, the groove
54
a
easily shrinks and the material easily deforms when overly used, hence losing the airtight effect.
Moreover, because of shrinkage and deformation of the groove
54
a,
the position of the swimming glasses will be too near the face so that the nose bridge of the user will contact with the hard joining ring
52
of the swimming glasses, resulting in discomfort or even abrasion of the skin of the nose bridge.
When the user swims, the water pressure will press the swimming glasses to shrink the grooves
54
a,
resulting in bad circulation of blood. Therefore, the swimming glasses cannot be worn for a long time. Moreover, when the swimming glasses are taken off, pressed marks will be generated on the face because of bad circulation of blood.
Therefore, the above pad structure of swimming glasses has inconvenience and drawbacks in practical wearing or use. The present invention aims to resolve the above problems in the prior art.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an improved pad structure of swimming glasses capable of effectively increasing the resiliency of swimming glasses and enhancing the comfort of wearing.
The secondary object of the present invention is to provide an improved pad structure of swimming glasses so that pressed marks generated on the skins of eye sockets because of bad circulation of blood can be avoided.
Another object of the present invention is to provide an improved pad structure of swimming glasses, wherein a plurality of enhancement structures are added and alternately disposed between the inner and outer side faces of die pad to alleviate the position of the swimming glasses and to prevent the abrasion of the skin of the nose bridge because of the contact of the nose bridge with the hard joining ring of the swimming glasses.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
