Swimming goggles

Abstract: A swimming goggle model, comprising: two lens frames, each lens frame accommodating a lens, and a first joining unit and a second joining unit on two opposite ends. At least one round string, pulled in sequence through the first and the second joining units of the two lens frames, maintains an appropriate span between the two lens frames. A headband device is joined in series to the two joining units on the outside edge of the two lens frames. Using this structural characteristic, the user can adjust the span of the round string between two lens frames, to adjust the span of the nose bridge.

Description: This invention is a model of swimming goggles for swimming pool purposes with a step-less nose bridge adjustment. 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 5 10 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. US-A-5857221 diseloses swimming goggles comprising a pair of eyecups held on the eyes by elastic cords that encircle the head. The cords connect the eyecups together to form a nose bridge and pass along tracks around the eyecups. They are secured at the rear of the head by a toggle lock. 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. Thus viewed from one aspect the present invention provides swimming goggles comprising: a first lens frame accommodating a lens positioned on a left side of a nose bridge; a second lens frame accommodating a lens positioned on a right side of the nose bridge; a first joining unit on the inside edge of each of the first lens frame and second lens frame adjacent to the nose; a second joining unit on the outside edge of each of the first lens frame and second lens frame remote from the nose; a first round string wound around the upper rim of each of the first lens frame and second lens frame and a second round string wound around the lower rim of each of the first lens frame and second lens frame so as to form the nose bridge and maintain a span between the first lens frame and second lens frame, each of the first round string and second round string being fixed to the first joining unit and the second joining unit on each of the first lens frame and second lens frame, whereby in use the span between the first lens frame and second lens frame is adjusted by the first round string and second round string, and a headband device joined to the second joining unit on each of the first lens frame and second lens frame, said headband device including at least a headband, wherein the first joining unit comprises a first round hole and a second round hole each with an inwardly tapering opening suitable for snapping the first round string and second round string respectively therein wherein the second joining unit comprises a clasping channel and a headband through-hole, whereby the clasping channel serves to fix in position an end of the first round string and second round string, wherein the swimming goggles further comprise: a fitting plate fitted in the headband through-hole on which there is an embedding seat embedded on said headband through the headband through-hole to fix the headband in position. In accordance with the invention, 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 nose bridge of the swimming goggles is formed by two round strings that are 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 strings, which are connected in a series connection to the two lens frames and produce an appropriate span. Through this structural characteristic; the user may adjust the span on the round strings of the two lens frames, to achieve nose bridge adjustment of the swimming goggles. The two round strings are wound on the upper and lower rims of the lens frames and a length at one end may be appropriately exposed on the outside of the lens frame to facilitate control in adjusting the span. The first joining unit is located on the inside edge of the lens frame and has two cylindrical channels with openings. The second joining unit is located on the outside edge of the lens frame and has two clasping channels and a headband through-hole. These openings and channels serve to properly position the two ends of the round strings that comprise the nose bridge. The headband through-hole serves to accommodate the penetration of the headband. Another characteristic of this invention is 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. Between the fitting plate and the second joining unit may be a first fitting and a second fitting unit that can be interlinked. Fig. 1 is a perspective view of a conventional swimming goggle design.
