Buckle set of swimming goggles (05-Jan-2010)

BACKGROUND OF THE INVENTION

I. Field of the Invention

The present invention relates to a buckle set, in which a strap is inserted for length adjustment, and specifically to a buckle set that allows the strap to be adjusted to a desired length from its two ends.

II. Description of the Prior Art

The buckle that fits onto a strap is commonly used to adjust the strap to a desired length. Among various buckles, tri-glide or vertical flip are the most popular. With reference to FIG. 1, which shows a tri-glide buckle of the prior art, the tri-glide buckle 102 fits onto a strap 103 attached to a pair of swimming goggles 101. As shown in FIG. 1, the strap is inserted into two slots respectively formed on two sides of the sealing frame of swimming goggles 10, and two ends of the strap 103 are inserted into the holes 1021 formed on the tri-glide buckle 102 so that the strap can be adjusted to a desired length.

Accordingly, the tri-glide buckle 102 can be positioned on a strap so as to set the strap to a desired length, the strap easily comes off the tri-glide buckle 102 though. The strap 103 is made of rubber and has its two ends inserted in the tri-glide buckle 102. When its two ends are pulled for length adjustment, the strap rebounds because of the rebound property resulting from its elasticity and would consequently come off the tri-glide buckle 102

SUMMARY OF THE INVENTION

In view of the foregoing drawbacks, it is desirable to develop a buckle design that substantially meets user demands and improves convenience and effectiveness in use. The main objective of the present invention is to provide a buckle set that is user-friendly and can be firmly positioned on a strap so as to set the strap to a desired length.

The buckle set provided by the present invention generally comprises three parts, namely a buckle seat, a buckle composed of two corresponding clasps, and a buckle hood. Insert two ends of a strap into said clasps so that the strap can be set to a desired length.

Desirable structure, assembly, and features of the present invention will be better understood from the detailed description and drawings that follow, in which various embodiments of the disclosed invention are illustrated by way of example.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIG. 2, which shows a three-dimensional view of the present invention, the buckle set 20 comprises a buckle seat 201, a buckle 202, and a buckle hood 203. The buckle seat 201 is mainly structured by a receptor 2011 that comprises a plurality of springs 2012, barriers 2015, pivot slots 2013, and two strap slots 2014. The barriers 2015 are formed nearby the springs 2012. The pivot slots 2013 are formed on flanks of the buckle seat 201. The strap slots 2014, into which the strap 30 is inserted, are formed on two ends of the buckle seat 201 respectively. The buckle 202 is composed of two corresponding clasps, each of which comprises a press stud 2024, two pivots 2021, two bumps (the first bump 2025 and the second bump 2023) and a pressing portion 2022. The first bump 2025 and the pressing portion 2022 are formed respectively on two ends of the buckle 202. The second bump 2023 is positioned between the pressing portion 2022 and the pivot 2021. The buckle hood 203 is a removable cover over the buckle seat 201 that comprises a pair of holes 2031. Ensconce the buckle 202 into the buckle seat 201 that the first bump 2025 is positioned against the spring 2012 and the second bump 2023 against the barrier 2015. Fit the buckle hood 203 onto the buckle seat 201, in which the buckle has fit in, the press studs 2024 would partially protrude from the holes 2031 so as to be pressed by one's thumbs.

With reference to FIG. 3, which shows an embodiment of the present invention, the buckle set 20 fits onto a strap attached to a pair of swimming goggles 40. By pressing the press studs 2024, the wearer can easily and quickly buckle up, unbuckle the buckle set 20, or adjust length of the strap.

With reference to FIG. 4, which shows unbuckling (I) of the present invention, the buckle set 20 comprises two strap slots 2014, in which two ends of the strap 30 are inserted. When the buckle 202 is unbuckled, the strap can run freely in the strap slots so as to easily and quickly be adjusted to a desired length. Also shown in FIG. 4, when the buckle 202 is unbuckled, the pressing portion 2022 of the buckle 202 is spaced apart from the strap 30 and the second bump 2023 from the barrier 2015 of the buckle seat 201. On the other hand, the first bump 2025 of the buckle 202 jostles against the spring 2012 of the buckle seat 201 so that the buckle 202 can be pushed back to its original position while the spring 2012 is rebounding by its elasticity.

With reference to FIG. 5, which shows buckling (II) of the present invention, the buckle set 20 is buckled up after the strap 30 is adjusted to a desired length. When the buckle 202 is buckled up to set the strap 30 at desired length, the strap 30 hardly comes off the strap slots because the pressing portion 2022 butts in one of the teeth 301 and the second bump 2023 jostles against the barrier 2015 of the buckle seat 201. The teeth 301 are formed on the surface of two ends of the strap 30. Moreover, pulling the strap 30 may cause a force in the direction as indicated by the arrow shown in FIG. 5. The force may push the second bump 2023 to further jostle against the barriers 2015 as well as cause the pressing portion 2022 to tightly press on the strap 30. As shown in FIG. 5, the buckle 202 is composed of two corresponding clasps, in which two ends of the strap 30 are inserted, so that the strap can be adjusted to a desired length from its two ends. The design of the two corresponding clasps favors users with an easy and effective way of adjusting length of a strap attached to swimming goggles from its two ends.

Accordingly, the present invention mainly uses a buckle that is composed of two corresponding clasps to facilitate the length adjustment of a strap that is attached to a pair of swimming goggles. Two ends of a strap are respectively inserted in said clasps so that the strap can be adjusted to a desired length from its two ends. In sum, the present invention achieves in providing a buckle set that is user-friendly and can be firmly positioned on a strap so as to set the strap to a desired length.
