ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lace buckle device with innovatory convenience for firmly fastening or releasing two ends of a lace, and more particularly to a lace buckle device which can effectively prevent two ends of a lace from being pulled out by force.
2. Description of the Related Art
A rope or a lace is commonly used in our daily life. A rope can be used to tie up the mouth of a bag. A lace is applied to tie the mouth of a belted topcoat or a lace shoe for a wearer to wear comfortably. Generally, two ends of a rope or a lace would be tied to form a slipknot so as to secure the rope or lace in position. When one end of the rope or lace being pulled, the slipknot will easily be untied. However, there are many drawbacks by means of tying a slipknot for securing a rope or lace in position. For example, it wastes time and is troublesome to tie a slipknot, and a slipknot is easy to be loosened or to become a fast knot and is not beautiful.
A conventional lace buckle device has been invented to overcome the drawbacks of tying a slipknot to fasten two ends of a rope or a lace. Referring to
FIG. 8
, the conventional lace buckle device includes a buckle base
80
and an operative rod
90
. An opening
81
is formed on the top of the buckle base
80
. A central hollow
82
is provided in the interior of the buckle base
80
, but the central hollow
82
does not penetrate through the bottom of the buckle base
80
. Two opposite passing holes
83
are provided in the side wall of the buckle base
80
. A top tray
91
is provided on the top of the operative rod
90
, and a protruding rod
92
is provided on the bottom of the top tray
91
. A passing hole
921
is provided to penetrate through the front and rear side walls of the protruding rod
92
, and below each end of the passing hole
921
is provided with a stopping strip
922
. A protruding block
923
is provided on the bottom of the protruding rod
92
.
Referring to
FIG. 9
, while being assembled, a spring
93
is placed into the central hollow
82
of the buckle base
80
, and then the operative rod
90
is inserted in the central hollow
82
with the direction of the passing hole
921
being in accordance with that of each passing hole
83
. At the same time, each stopping strip
922
is forced to pass the opening
81
and stop against each passing hole
83
so as to make the protruding rod
92
be caught in the central hollow
82
. Because of the elasticity of the spring
93
, the passing holes
83
and the passing hole
921
are slightly staggered, and the passing holes
83
do not respectively wholly lap over each end of the passing hole
921
. After the top tray
91
of the operative rod
90
being pressed down, the operative rod
90
will move downward to make the passing hole
921
accord with the passing holes
83
, and then two ends of a rope or a lace
94
can penetrate through the overlapped passing holes
83
and
921
. When the top tray
91
being released, referring to
FIG. 10
, two ends of a rope or a lace
94
will be fastened to prevent from being pulled out by means of the stagger of the passing holes
83
and
921
.
However, there are still drawbacks in the above-mentioned conventional lace buckle device although it is more convenient to be operated and beautiful to look than a slipknot tied by hands. The conventional lace buckle device can function to fasten or release two ends of a lace by means of the spring
93
and the operative rod
90
which cooperate to change the positions of the passing hole
921
, but, when two ends of the lace being clamped by the spring
93
and the operative rod
90
, they can still be easily pulled out of the buckle device by forceful pulling. It can not have the perfect efficiency to fasten two ends of a lace.
SUMMARY OF THE INVENTION
Therefore, the present invention is to provide a lace buckle device that substantially obviates the drawbacks of the related conventional art.
An object of the present invention is to provide a lace buckle device that is convenient for operating to fasten or release two ends of a lace.
Another object of the present invention is to provide a lace buckle device whose catching rims of both slant holes improve perfect efficiency to prevent two ends of a lace from being pulled out by forceful pulling while in clamped condition.
To achieve these advantages, a lace buckle device in the present invention includes a buckle base, an operative rod and a spring. The buckle base is provided with a central vertical hollow, and a lateral hole is provided to penetrate through the centers of the front and rear walls of the buckle base. Two slant holes are respectively provided at the left and right sides of the lateral hole and respectively slantwise extend to and through the left and right side walls of the buckle base. A catching rim is formed on each shorter section of each slant hole in the left side wall or right side wall. The operative rod is provided with a lateral passing hole penetrating through the front and rear walls. After the spring and the operative rod being successively inserted in the central vertical hollow, each end of a lace can be inserted into each end of the slant hole in the left side wall or right side wall and out of each other end of the slant hole in the front wall, and then both ends of a lace are reversely inserted into the front end of the lateral hole and penetrate through the lateral passing hole of the operative rod and out of the rear end of the lateral hole of the buckle base so as to make two ends of a lace be firmly fastened by the clamp of the spring and the operative rod and the catch of the catching rims.
