ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a type of swimming goggles, or specifically an innovated structure of swimming goggles with a protective pad that encompasses two lens frames in one single space to provide wearing comfort and a wide view.
2. Description of Prior Art
The two lens frames of conventional swimming goggles, regardless of a wide variety of structural modifications, are designed to cover two eye sockets separately. In other words, the conventional design of swimming goggles has been aimed at preventing leak by covering the eye sockets. Therefore, whether sponge type or sucker type, the protective pads are designed as separate units on the lens frames. When the conventional swimming goggles are worn by the user's face, there will be a suction force applied by the protective pads around the eye sockets, which would result in a certain degree of discomfort after an initial period of use under water. Furthermore, because of the limited area of lens of conventional swimming goggles, the field of vision is quite limited. The most direct way to improve the drawback of narrow field of vision in conventional swimming goggles, of course, is to enlarge the lens frames. But the integral structural of the entire swimming goggles will be changed after the lens frames are enlarged. Then, wearing comfort will be a new problem to be solved.
BRIEF DESCRIPTION OF THE INVENTION
1. Objective of the Invention
The main objective of this invention of swimming goggles is to provide a type of swimming goggles with wearing comfort and extensive field of vision. With a protective pad that serves concurrently the function of a facemask, the swimming goggles will not cause pressure on the user's eyes, and will provide excellent prevention against leak by encompassing two lens frames in one space.
2. Characteristics of the Invention
This invention of swimming goggles is characterized in that: the lenses and protective pad of the swimming goggles are compressed to one unit with the lens frame main unit, wherein, the lens frame main unit comprises a frame that has a central connector, with at least two openings on the frame, and an accommodating groove on the inside rim of the frame.
Based on the above characteristic, the lens frame main unit is compressed and fixed to become a pressing member, the pressing member comprising: a bottom cover and a top cover that can be combined as one unit, wherein on opposite faces of the bottom cover and top cover are matching snappers and fasteners, and a positioning post that serves to accommodate the insertion and position a headband of the swimming goggles.
Based on the above characteristic, the central connector uses a rivet device to join the upper and lower rims of the lens frame main unit, the rivet device comprising a positioning unit on the frame and a rivet that is engaged with the positioning unit.
Based on the above characteristic, the lens frame main unit comprises a first frame, a second frame and a third frame that can be assembled as one unit, wherein the first frame has a central connector, while the two ends of the second and third frames can be respectively assembled to the pressing member. The positioning unit of the rivet device can be extended along with the central connector of the first frame, on which is a hollow shaft that serves to join the ends of the first and third frames, the hollow part of the hollow shaft serving to be fastened by the rivet, to fix the ends of the second and third frames to the central connector.
At the far ends of the first, second and third frames away from the central connector are openings that can be tightened to the bottom cover and top cover of the pressing member, the snappers and positioning post of the bottom cover and top cover serving to join the first, second and third frames by fixing the openings at their ends.
Yet another characteristic of this invention is that, the protective pad has a face contact part and a lens accommodating part, wherein the face contact part can cover the upper parts of eyebrows and lower parts of eye sockets, the lens accommodating part can accommodate the lenses before they are integrally accommodated in the first, second and third frames.
