ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a type of swimming goggles enabling natural contact with the user's eye sockets for wearing comfort, without the risk of water seeping in.
2. Description of Related Art
Conventionally swimming goggles have included the function of a protective pad to enable wearing comfort and prevention from water seepage. The protective pads in conventional swimming goggles generally involve a sponge type or a sucking gasket type, in which, the side in contact with the user's face is designed to be flat and of consistent thickness. People's eye sockets, including upper and lower parts of eye socket and the area near the nose bridge, however, do have inconsistent depressions. So they have to be pressed and squeezed against the user's face in order to ensure tight contact with the eye sockets. As can be understood from
FIGS. 1 and 2
, when the swimming goggles
1
are not in use and are laid at an angle parallel to the human eyes, the distance t1 from the protective pad
10
of the swimming goggles
1
to the upper eye socket is smaller than the distance t
2
from the protective pad
10
to the lower eye socket (please refer to FIG.
1
), so they must be squeezed down on the face to prevent water seepage by pressing the protective pad
10
in closer contact with the lower eye socket. However,
FIG. 2
shows the result after the pressing and squeezing process. Though the protective pad
10
and the upper and lower eye sockets are in closer contact, there is the existence of a clearance t
3
. In other words, the area of contact is large enough and sufficient. After being used for a while, the user will feel discomfort on the rims of eye sockets caused by the squeezing effect, especially on the lower parts of eye sockets. Discomfort will make the user twitch his face, which in turn results in a gap t
3
and subsequent water seepage. In addition to that, the area of eye sockets near the nose bridge is particularly depressed. The conventional protective pad could not ensure contact in a larger area, so it will easily result in water seeping through. Furthermore, because the lower eye sockets are more depressed than the upper eye sockets, the squeezing process aimed at the lower eye sockets will result in an oblique angle between the lenses
10
of the swimming goggles
1
and the eyes
2
, which means poor light reflection.
SUMMARY DESCRIPTION OF THE INVENTION
The main objective of this invention of swimming goggles is to provide a comfortable model of swimming goggles, which are shaped to fit the contours of the eye sockets. In other words, the protective pad is shaped to match the configuration of the upper and lower eye sockets and the depression of the nose bridge, to enable natural contact and wearing comfort, so that there will be no water seeping through even when the user is twitching his face muscles.
Another objective of this invention of swimming goggles is to provide a type of swimming goggles that enables parallel status of the lenses and the user's eyes, designed to have inconsistent thickness of the protective pad of the swimming goggles to match the outlines of eye sockets, so that a parallel angle can be maintained between the lenses and the user's eyes, and an excellent light reflection performance can be maintained when the goggles are in use. This invention of swimming goggles is characterized in that: the protective pad of the swimming goggles is designed to have inconsistent thickness, and specifically, the design of protective pad is aimed at the common properties around the rims of people's eye sockets: based on the different depressions of the upper and lower eye sockets and the depression of the nose bridge, the protective pad is shaped in inconsistent thickness to make up for the different depressions and fit the rims of eye sockets.
Another characteristic of this invention of swimming goggles is a non-flat surface on the side in contact with the user's face, that is, the side of the protective pad in contact with the face is inclined to suit the upper and lower eye sockets and the depression of the nose bridge, so that it will be in tight contact with the eye sockets.
