Swimming Goggles

1. Field of the Invention

A The present invention relates to a pair of swimming goggles which provides increased comfort during wearing.

2. Description of the Related Art

Swimming goggles may protect the swimmers' eyes and provide an increased view. FIG. 5 of the drawings illustrates a pair of conventional swimming goggles which includes two frames 72 of plastic material interconnected by a connecting member 73, two rigid lenses 71 respectively received in the frames 72, and a strap 74 which extends through two slots 721 respectively defined in outer sides of the frames 72, thereby defining an upper strap section 742 and a lower strap section 741 in which one of the strap sections, e.g., the upper strap section 742 has no buckle mounted thereto, while the lower strap section 741 has a buckle 75 mounted to an end thereof for adjustably embracing the head of the user (the two distal ends of the strap 74 may be directly knotted together if no buckle is provided). When in use, it often takes a considerable time for the user to adjust the length of the strap 74 (i.e., the length of the upper strap section 711 without buckle thereon) and to adjust the tightness of the upper and lower strap sections 742 and 741. The wound areas 743 of the strap 74 is not securely retained and thus may slide and thus exaggerate the difficulty of length adjustment of the strap 74. In addition, when in use, the lower strap section 741 may press against the ears of the users and thus result in discomfort, as shown in FIG. 6. Furthermore, the upper and lower strap sections 742 and 741 are relatively long and thus tend to entangle with each other which further exaggerates the difficulty of length adjustment of the strap 74.

Therefore, there has been a long and unfulfilled need for a pair of improved swimming goggles which mitigates and/or obviates the above-mentioned drawbacks.

A pair of swimming goggles in accordance with the present invention generally comprises two frames of plastic material interconnected by a connecting member therebetween, two rigid lenses respectively received in the frames, a strap, two clamping blocks each having a bore, and a buckle. Each frame includes a slot defined in an outer side thereof. The strap includes a first end, a second end, and a mediate section. Each of the first end and the second end of the strap is extended through the associated block, wound through the associated slot, and then again extended through the associated clamping block, thereby forming an upper strap section and a lower strap section which are adapted to be located at a position above the ears of a user. The first end and the second end of the strap are securely attached to the buckle, thereby allowing adjustment of the length of the strap in response to the shape of the head of the user. The bore of each clamping block allows the mediate section of the strap to be extended twice and thus tightly clamped therein.

By such an arrangement, the length of the strap can be easily adjusted in response to the shape of the user's head, thereby providing an increased comfort. In addition, the clamping blocks may retain the wound areas in position, thereby eliminating the difficulty of length adjustment of the strap. Furthermore, the lengths of the upper and lower strap sections are smaller than those in the conventional design, thereby eliminating entangling of the upper and lower strap sections as well as the difficulty of adjustment of the length of the strap. Preferably, the clamping block is made of buoyant material such that the swimming goggles may float on the water surface and thus be easily observed when lost in the water.

Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

FIG. 1 is a perspective view, partly exploded, of a pair of swimming goggles in accordance with the present invention;

FIG. 2 is a cross sectional view of a clamping block of the swimming goggles in accordance with the present invention;

FIG. 3 is a perspective view of the swimming goggles of the present invention;

FIG. 4 is a schematic view illustrating the use of the swimming goggles of the present invention;

FIG. 5 is a perspective view, partly exploded, of a pair of conventional swimming goggles; and

FIG. 6 is a schematic view illustrating the use of the swimming goggles of the conventional swimming goggles.

Referring to FIGS. 1 to 4 of the drawings and initially to FIGS. 1 to 3, a pair of swimming goggles in accordance with the present invention generally includes two frames 2 of plastic material interconnected by a connecting member 3 therebetween, two rigid lenses 1 respectively received in the frames 2, a strap 4, two clamping blocks 6 each having a bore 61, and a buckle 5. Each frame 2 includes a slot 21 defined in an outer side thereof. The strap 4 includes a first end 44, a second end 45, and a mediate section 46. Each end 44, 45 of the strap 4 (of elastic material) is extended through the associated block 6, wound through the associated slot 21, and then again extended through the associated clamping block 6, thereby forming an upper strap section 42 and a lower strap section 41 (see FIG. 3). The first end 44 and the second end 45 of the strap 4 are securely attached to the buckle 5, thereby allowing adjustment of the length of the strap 2 in response to the shape of the head of the user.

As shown in FIG. 2, the bore 61 of each clamping block 6 allows the mediate section 46 of the strap 4 may be extended twice and thus tightly clamped therein. Referring to FIG. 4, when in use, the ears of the user need not be pressed by the lower strap section 41, thereby providing an increased comfort. It is appreciated that the clamping blocks 6 may retain the wound areas 43 (see FIG. 3) in position, thereby eliminating the difficulty of adjustment of the length of the strap 4. In addition, the clamping blocks 6 may be made of buoyant material, such that the swimming goggles may float on the water surface when lost in the water.

Thus, the swimming goggles of the present invention has the following advantages:

(1) the length of the strap 4 can be easily adjusted in response to the shape of the user's head, thereby providing an increased comfort;

(2) the clamping blocks may retain the wound areas 43 in position, thereby eliminating the difficulty of adjustment of the length of the strap 4;

(3) the lengths of the upper and lower strap sections 41 and 42 are smaller than those in the conventional design, thereby eliminating entangling of the upper and lower strap sections as well as the difficulty of length adjustment of the strap 4; and

(4) the clamping blocks are buoyant such that the swimming goggles may float on the water surface and thus be easily observed when lost in the water.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
