Description

BUCKLE FOR SWIMMING GOGGLES

1. FIELD OF THE INVENTION

[0001] The present invention relates to a buckle for swimming goggles, and particularly to a buckle for swimming goggles, which allows to adjust a head strap directly without the need of taking the swimming goggles down and do not nip users' hair when the swimming goggles are worn.

2. BACKGROUND OF THE INVENTION

[0002] Buckles are popularly used to adjust head straps of swimming goggles. Ordinarily, the head straps are drawn along guiding holes in the buckles. The swimming goggles have to be taken down before the head straps are adjusted. To solve this problem, TW Utility patent application Nos. 91220914, 92216640, 93208471, 9421182, and U.S. Patent Nos. 09/034,907, 10/420850, 10/873260, and etc. put forward some solutions.

Generally speaking, in these solutions, buckles for swimming goggles are pressed to allow a head strap to be adjusted without taking down swimming goggles. The buckles commonly have pressing plates pivoting to the swimming goggles according to leverage principle. A first end of a pressing plate abuts against stopping grooves of the head strap. In the event that a second end of the pressing plate is pressed, the first end of the pressing plate disengages from the head strap, allowing the head strap to be adjusted.

[0003] However, the buckles in prior art are exposed out of manual portions of the swimming goggles, and tend to nip users' hair when the swimming goggles are worn.

SUMMARY OF THE INVENTION

[0004] Accordingly, an object of the present invention is to provide a buckle for swimming goggles, which allows a head strap to be adjusted easily without taking down the swimming goggles, and at the same time avoiding the users' hair being nipped or trapped in the buckle.

[0005] According to one aspect of the present invention, the buckle for swimming goggles comprises a connecting base, a pressing member, a button, a cover, a wrapping layer and a mounting element. The connecting base defines a slot for allowing a head strap to be movable therethrough.

The pressing member pivots to the connecting base by means of leverage.

The pressing member has a biasing wall integrally formed on an end thereof for abutting against stopping grooves of the head strap, and a free end opposite to the biasing wall. The button controls the pressing member to disengage from the stopping grooves of the head strap. The cover is assembled to the connecting base. The wrapping layer is provided on an outward side of the cover, and envelops the button. The mounting element is formed between the connecting base and the cover for mounting on the left/right frame of the swimming goggles.

[0006] The wrapping layer is integrally formed with the cover, alternatively the wrapping layer is separately formed and locks with the cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Fig. 1 shows a buckle 1 for swimming goggles according to a first embodiment of the present invention. With reference to Fig. 1, a buckle 1 for swimming goggles comprises a connecting base 2, a pressing member 3, a cover 4 and a wrapping layer 5. The connecting base 2 defines a slot 20 for allowing a head strap (not shown) movable therethrough, and shaft holes 22 and locking grooves 23 at both sides thereof. A mounting element 21 is formed between the connecting base 2 and the cover 4 for mounting on a left/right frame 6 (shown in Fig. 4) of the swimming goggles. In the first embodiment, the mounting element 21 includes positioning posts integrated with the connecting base 2 for assembling to prescribed assembling holes of the left/right frame 6, as shown in Fig. 4.

[0014] The pressing member 3 pivots to the connecting base 2 by means of leverage, and forms pivotable connection with the left/right frame 6 complying with leverage principle. The pressing member 3 has a biasing wall 31 integrally formed on an end thereof, and a free end (not labeled) opposite to the biasing waIl 31. The biasing wall 31 abuts against stopping grooves of the head strap. The pressing member 3 includes a connecting shaft 30 for assembling on the shaft holes 22 when assembled. A button 32 and a resilient portion 33 are integrally formed on the free end of the pressing member 3 and opposite to the biasing wall 31. The button 32 controls the pressing member 3 to disengage from the stopping grooves of the head strap. In this embodiment, the button 32 is arranged near a center of the connecting shaft 30 for manual operation. The biasing wall 31 moves reversely along an arcuate course when the button 32 is pressed. The resilient portion 33 provides returning force for the pressing member 3 thereby retaining the button 32 movable even when assembled. In this embodiment, the resilient portion 33 includes a pair of curved pegs 331,332 on opposing ends of the connecting shaft 30. In another embodiment, the button 32 is integrally formed on the cover 4 and corresponds to the free end of the pressing member 3 in assembly. As an example, the cover 4 defines a through hole 41 therein, and the button 32 is formed on an inner wall of the through hole 41. The resilient portion 33 is a compressible spring formed in a movement course of the free end of the pressing member 3.

[0015] The cover 4 is assembled to the connecting base 2, and forms latching poles 40 for corresponding to the locking grooves 23. A through hole 41 is defined in the cover 4, a part of the button 32 extending beyond the cover 4.

[0016] The wrapping layer 5 is integrally formed on an outward side of the cover 4, and envelops the button 32 entirely. A rib 50 is formed on the wrapping layer 5 and corresponds to the through hole 41 of the cover 4 for facilitating touching feeling and pressing operation. In other embodiments, the wrapping layer 5 is separately formed and locks with the cover 4.

[0017] Figs. 2 and 3 show the assembled buckle 1. Especially viewed from Fig. 3, the button 32 is fully shrouded by the wrapping layer 5. The exterior of the buckle I is smooth without aperture exposed out, thereby avoiding nipping users' hair. The rib 50 facilitates users to feel comfortable and operate exactly. Further referring to Fig. 4, the buckle 1 is assembled on a left/right frame 6 of the swimming goggles. An assembling hole 60 is defined in the left/right frame 6 for engaging with the mounting element 21 of the connecting base 2. The cover 4 and the connecting base 2 are assembled firmly on the left/right frame 6.

[0018] Figs. 5 and 6 respectively show a second embodiment and a third embodiment of the present invention. Referring to Fig. 5, the buckle 1' of the second embodiment is similar to the buckle 1 of the first embodiment except that a resilient portion 33' has a curved peg 330' alone. Referring to Fig. 6, the buckle 1" of the third embodiment is similar to the buckle 1 of the first embodiment as well. A pressing member 3" of the buckle 1" is a planar plate, and forms a connecting shaft 30" on a middle portion thereof.

A biasing wall 31" is formed on a side of the connecting shaft 30", and a button 32" is formed on another side of the connecting shaft 30" opposite to the biasing wall 31". A left/right frame 6" forms an arcuate portion 61" on a side thereof and serves as the resilient portion 33 of the buckle 1 in the first embodiment. In other embodiments, the arcuate portion 61" may be tongue-like, or the resilient portion 33 is a compressible spring separately.

Differences of these embodiments mainly lie in ways for providing returning force for the pressing member. A wrapping layer 5' of the second embodiment and a wrapping layer 5" of the third embodiment are identical to the wrapping layer 5 of the first embodiment. In the second embodiment, the wrapping layer 5' envelops a button 32'. In the third embodiment, the wrapping layer 5" envelops a button 32". Similarly, the buckle 1',l" also have smooth surface without apertures, thereby avoiding nipping users' hair.

[0019] It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
