SWIIv7wiING GOGGLES
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
[0001 ] The present invention relates to a pair of swimming goggles, and
particularly to swimming goggles having buckles for adjusting wearing
length of a head strap thereof directly when the swimming goggles are
worn.
2. RELATED ART
[0002] Swimming goggles are worn with a head strap thereof being
fastened. to a user's head. The head strap is usually adjustable to be tight
or loose to the user's head thereby making the user comfortable. Referring
to Fig. l, conventional swimming goggles 7 include a head strap 70 and two
buckles 71 at opposite sides thereof. Each buckle 71 deftnes two slots 710,
711 therein. Each of opposite free ends 70I, 702 of the head strap 70
extends through the two slots 710, 711 of each buckle 71 in turn and then is
wound at the buckle 71 thereby connecting the head strap 70 to the buckles
71. The connection between the head strap 70 and the buckles 71 is
adjustable through one or both of the free ends 701, 702 of the head strap 70
sliding along the slots 710, 711 of the buckles 71. Thus, the head strap 70
is adjustable to fasten the swimming goggles 7 to the user.
[0003] However, the swimming goggles 7 must be taken off before the
adjustment of the head strap 70. Then the swimming goggles 7 are worn
again after the adjustment of the head strap 70. It is hard to fit the
swimming goggles 7 to the user though once of the adjustment. In fact, it
often need several times of adj ustment to fittingly wear the swimming
goggles 7. So, the user has to wear and take off the swimming goggi~s 7
i

several times. Even so, the user may still feel uncomfortable to wear the
swimming goggles 7. It is inconvenient to adjust the swimming goggles 7.
SL11v1~NiARY OF THE INVENTION
[0004] Accordingly, an object of the present invention is to provide a pair
of swimming goggles which is ready to adjust wearing length of a head strap
thereof for being fit to a user, and which does not need to be taken off
during
the adjustment.
[0005] To achieve the above-mentioned object, a pair of swimming
goggles in accordance with the present invention includes left and right
goggle frames, a connection bridge connected between the left and right
goggle frames, a pair of buckles respectively attached to the left and right
goggle frames opposite the connection bridge, and a head strap adjustably
fastened to the buckles. Each goggle frame has outer and inner surfaces.
A receiving hole is defined between the outer and inner surfaces of each
goggle frame and receives a lens therein. Each buckle ihcludes a base and
a cover attached to the base. A chamber is cooperatively deftned in the
base and the cover and receives a shaft and a fastener therein. An entrance
is defined between the base and the shaft. Au exit is defined between the
shaft and the cover. The fastener is adjacent to the shaft and includes a
handle and an engagement protrusion. Each of free ends of the head strap
extends into the entrance of the buckle, extends out of the exit of the buckle
and abuts against the shaft. Each free end of the head str ap selectively
engages with the engagement protrusion of the buckle thereby fixing the
head strap to the buckle. The handle is rotatable to disengage the
engagement protrusion from the head strap whereby wearing length of the
head strap is adjustable through moving the free ends of the head strap
relative to the shaft.
