Swimming goggle buckle

(a) Field of the Invention

The present invention relates to an improvement of a swimming goggle buckle, having a goggle main body, two single buckle complexes, and a headband, wherein each single buckle complex connecting with an end of the goggle main body at one end and with the headband at another end. The present invention is easy in assembling, difficult in disassembling, and convenient in adjusting the headband. In addition, special considerations in design were provided for the single buckle complex by utilizing a single model, having an upper and a lower model adhering together, which eliminating mechanic structures therein, thereby reducing modeling cost, enhancing modeling strength, and lowering failure rate during production. As a result, the single model enabling the present invention lowering cost, increasing durability, and enhancing competitiveness.

(b) Description of the Prior Art

The main defect of a conventional swimming goggle is that some elements are formed by two separate elements combining together, which can be inferior in strength and also complicated in manufacturing, comparing with that of a single element.

Referring to FIGS. 1A and 1B . A conventional swimming goggle includes a goggle main body a with an extension strap a 1 connecting to each end, wherein a block b, formed by combining an element b 1 and an element b 2 , connecting to an end a 2 of the extension strap a 1 and a headband c formed inside the block b. The conventional swimming goggle thereof involves two elements combined to form the block b, being an inferior structure in strength, and also has many parts, which complicating assembling, causing much trouble, and increasing cost in production.

Referring to FIG. 1C . Another conventional swimming goggle is formed by joining a buckle d to an extension strap a by blow-modeling of the buckle d embedded in a model of the extension strap a, which improves strength but with an adverse effect of increasing failure rate during production when combining the buckle d with the extension strap a in a model. Besides, the headband c is a two-element structure, too.

It is an objective of the present invention to provide a buckle structure formed at both ends of a goggle main body, being modeled in a single body, enabling easy in assembling, difficult in disassembling, and convenient in adjusting headband, as well as lowering cost, increasing durability, and enhancing competitiveness.

It is another objective of the present invention to provide the buckle structure to prevent looseness and distortion and increasing comfort when wearing.

To achieve objectives hereinabove, the present invention includes a single buckle complex formed at each end of a goggle main body, wherein a cantilever structure formed in the front fastening the goggle main body and also preventing looseness and distortion, a barb structure formed in the middle enhancing fastening capability and making unintentional disassembly more difficult, and a shaped buckle (i.e. a buckle having two spaced crossbars) to form three spaced openings with a gap formed in the rear fixing a headband while also facilitating headband adjustment through the gap.

The single buckle complex, possessing functions of connection, adjustment, and fastening after assembling, works by fastening the III-shaped buckle in the rear to the headband and by inserting an end of the goggle main body from the bottom of the cantilever structure and further hooking at the barb structure thereof, wherein, the III-shaped buckle fastening the headband while also with the gap facilitating headband adjustment, a surface of the goggle main body contacting tightly against a base of the cantilever structure enabling the single buckle complex fixing on the goggle main body when the headband being tightened, which preventing looseness and distortion as well as increasing comfort when wearing, and the barb structure making the disassembling work hard and also enhancing fastening capability.

With the single buckle complex forming separately with the goggle main body, the production failure rate can then be lowered, thereby increasing the production success rate.

To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

Referring to FIGS. 2 and 3 . The represent invention is an improvement of a swimming goggle buckle, including a goggle main body 10 , a headband 20 , and two single buckle complexes 30 , wherein, the goggle main body 10 including a nose pad, a rim, glass lens, and face contacting pads, as well as openings 11 at both ends, each single buckle complex 30 connecting with the goggle main body 10 at one end and with the headband 20 at another end, and the headband 20 being formed by a kind of elastic material. Referring to FIGS. 4A and 4B . The single buckle complex 30 is formed with a barb structure 31 in the middle, a cantilever structure 32 in the front, a shaped buckle 33 in the rear, and a gap 33 a at an end portion of the shaped buckle 33 .

Referring to FIG. 5 . By inserting an end of the goggle main body 10 from the bottom of the cantilever structure 32 to hook the opening 11 at the barb structure 31 thereof, the goggle main body 10 thereby contacting tightly against the base of the cantilever structure 32 when the headband being tightened, enabling the single buckle complex 30 fixing on the goggle main body 10 to prevent looseness and distortion and to increase comfort when wearing. Meanwhile, the III-shaped buckle 33 in the rear fastens the headband 20 while also with the gap 33 a to facilitate adjustment of the headband 20 .

In summary, the present invention of the swimming goggle buckle, having a goggle main body and single buckle complexes connected with a headband, is easy in assembling, difficult in disassembling, and convenient in adjusting headband, besides having functions in preventing looseness and distortion and increasing comfort when wearing. Thereby, the present invention is both practical and advanced.

It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
