ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an assembly system for securing an adjusting strap to a frame of goggles with innovatory convenience and security features, and more particularly to an assembly system that can promptly and firmly assemble an adjusting strap to a frame of goggles.
2. Description of the Related Art
Many people whose eyes may be hurt by strong rays while working must wear industrial safety goggles to protect their eyes. Besides, many people who swim or work in the water must wear swim goggles to protect their eyes. Generally, a pair of conventional goggles is provided with an adjusting strap for a wearer to adjust the length to fit the wearer's head, so as to wear securely and comfortably.
Referring to
FIGS. 1
,
2
and
3
, a pair of conventional goggles
10
, is composed by an inner frame
101
and an outer frame
102
. One jointing block
20
is provided to secure to each end of the goggles
10
and to be passed by an adjusting strap
30
. Each jointing block
20
is provided with two protrusions
201
at both sides of the head portion, and the head portion of each jointing block
20
is inserted into each cavity
1012
in each protective ear
1011
of each inner frame
101
, so as for the two protrusions
201
of each jointing block
20
to be caught in each cavity
1012
of each protective ear
1011
. Each hook member
1021
of the outer frame
102
is inserted into each cavity
1012
to be against the catching piece
1013
of each protective ear
1011
, so as to prevent the head portion of each jointing block
20
from falling off.
Referring to FIGS.
4
,
5
and
6
, the other portion of each jointing block
20
is a buckle ring with an operating strip
202
, on each operating strip
202
is provided with a flange
2021
, and a row of teeth are provided at the front end of each operating strip
202
. When each operating strip
202
is moved outward by operating each flange
2021
, each end of the adjusting strap
30
can pass through each buckle ring of each operating strip
202
and reach a predetermined position. When each flange
2021
of each operating strip
202
is released, the row of teeth of each operating strip
202
will grip the crisscross grains
301
in the adjusting strap
30
, so as to make the adjusting strap
30
be secured to the frame of the goggles
10
.
Although the conventional adjusting strap
30
can be secured to the frame of the goggles
10
by means of two jointing blocks
20
, the parts are numerous, and the assembly process of each jointing block
20
to the goggles
10
is complicated, so as to add material and process cost. Moreover, because the crisscross grains
301
in the adjusting strap
30
are not deep enough and easily scraped away after a period of time, they can not be gripped firmly by the row of teeth of each operating strip
202
, and the adjusting strap
30
will be easily moved when being slightly pulled.
SUMMARY OF THE INVENTION
Therefore, the present invention is to provide an assembly system for securing an adjusting strap to a frame of goggles that can substantially obviate the drawbacks of the conventional arts.
An objective of the present invention is to provide an an assembly system that can promptly and firmly assemble an adjusting strap to a frame of goggles.
Another objective of the present invention is to provide an assembly system which can save cost and time for assembly.
Yet another objective of the present invention is to provide an assembly system whose each jointing block has an operating member being provided with a flange convenient for being operated by a user.
It is a further objective of the present invention is to provide an assembly system whose adjusting strap will not be scraped away after being used for a long time.
Accordingly, an assembly system for securing an adjusting strap to a frame of goggles includes a pair of goggles, two jointing blocks and an adjusting strap. The pair of goggles are provided with a cavity at each side of the frame for a jointing block. One side of each cavity has a groove, and a hollow is provided in each end of the lens. Two jointing blocks are respectively connected with one end of the frame. Each jointing block has a front inserting portion, and a hooking foot is provided on the inward surface of each inserting portion so as to be caught in each hollow of the lens, and the other portion of each jointing block is formed as a buckle ring. An upper operating member extends above each buckle ring, and each operating member has a flanged curve at the front end. Both end sections of the adjusting strap are provided to respectively pass each buckle ring, a row of spaced teeth are provided on each end section, and each tooth has a slant surface on one side. The middle section of the adjusting strap is provided with a plurality of flanged granules.
