ABSTRACT:
FIELD OF THE INVENTION
This invention is a model of swimming goggles for swimming pool purposes with a step-less nose bridge adjustment.
BACKGROUND OF THE INVENTION
Conventionally, a pair of swimming goggles has a span between two lens frames adjusted to suit the user's nose shape. There are only three steps in the nose bridge adjustment (as shown in FIG.
1
). A conventional nose bridge has a structural checking mechanism design for adjustment . Adjustment in the natural direction will be much easier than in the reverse direction. Referring to
FIG. 1
, which illustrates conventional swimming goggles
5
, wherein the nose bridge is a plate body
51
with several ribs
510
resting on a seat
520
of the lens frame
52
. Two opposite sides of said ribs
510
are designed on a guided surface. For the checking effect, the angle of the guided surface on one side is larger. The larger angle requires much effort in adjusting the span. It would even become impossible to make the adjustment if it is operated improperly. One point that deserves attention is that, when the ribs
510
on the plate body
51
are pulled for adjustment, the ribs become compressed and deformed by the seat
520
. After extended use, the ribs
510
are flattened and no longer engage the seat
520
, resulting in loosening of the swimming goggles, or even the risk of water seepage. In other cases, the user may not know how to make the 3-step adjustment, so they will not feel comfortable. In view of this, it has become important for designers to present a type of swimming goggles to suit various nose ridge configurations.
BRIEF DESCRIPTION OF THE INVENTION
The primary objective of this invention is to provide a type of swimming goggles with a step-less nose bridge adjustment. Using an innovative design, the nose bridge span of the swimming goggles can be freely adjusted by the user to suit the user's nose ridge and to ensure wearing comfort.
Another objective of this invention is to provide a type of nose bridge span adjustment that uses a twitching and snapping positioning to provide operational convenience.
This swimming goggle invention is characterized by the two ends of the longer axis of the lens frames of the swimming goggles respectively have a first joining unit and a second joining unit. The formation of the nose bridge of the swimming goggles has a round string, that is positioned along the rims of the lens frames onto the first and second joining units of the two lens frames, which maintains an appropriate span between the two lens frames. In other words, the nose bridge is formed by the round string, which is connected in a series connection to the two lens frames and producing an appropriate span. Through this structural characteristic, the user may adjust the span on the round string ofthe two lens frames, to achieve nose bridge adjustment of the swimming goggles.
Through the above characteristics, the two round strings are wound on the upper and lower rims of the lens frames, with a length appropriately exposed from one end on the outside of the lens frames, to facilitate control in adjusting the span.
Through the above main characteristic, the first joining unit is located on the inside edge of the lens frame, having two round holes with openings. The second joining unit is located on the outside edge of the lens frame, having two clasping channels and a headband through the holes. These openings and channels serving to properly position the two ends of the round holes that comprise the nose bridge. Said headband through holes serves to accommodate the penetration of the headband.
Another characteristic of this invention lies in that, on the headband through hole is a fitting plate. On the said fitting plate is an embedding seat to accommodate the insertion of the headband and embed it on said headband through a hole to effectively clasp and position the headband.
Another characteristic of this invention is that between the fitting plate and the second joining unit are a first fitting unit and a second fitting unit that can be interlinked.
