ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a vanity, and more particularly to a method for making integrally the vanity.
BACKGROUND OF THE INVENTION
As shown in
FIGS. 1-3
, the Taiwan Patent No. 326391 discloses a method for making integrally a mirror frame. The method includes the use of an exclusive machine, which comprises a lower rotary shaft
50
provided in the top thereof with a U-shaped receiving seat
51
which is in turn provided with an upper rotary shaft
60
concentric with the upper rotary shaft
50
. The upper rotary shaft
60
is provided at the bottom end thereof with a press wheel
61
which is in turn provided inn the underside thereof with a soft plastic pad
610
. The receiving seat
51
is provided in one side thereof with a side press wheel
63
and a locating wheel
62
, as shown in FIG.
1
.
The method involves a step in which a mirror frame
40
is arranged on the receiving seat
51
. The mirror frame
40
has one side which is formed by punching and pressing. The side edges of the mirror frame
40
are not yet punched and pressed. The side edges face upward and are jutted out of the top edge of the receiving seat
51
, as shown in FIG.
1
. In the meantime, the mirror frame
40
is provided sequentially with a mirror
41
, a sponge body
42
, and another mirror
41
. As the lower rotary shaft
50
is rotated, the receiving seat
51
and the mirror frame
40
are actuated to turn. In the meantime, the upper rotary shaft
60
and the press wheel
61
are actuated to turn so as to descend to press against the mirror
41
and the sponge body
42
, as shown in FIG.
2
. The locating wheel
62
is descended to press against the frame side of the mirror frame
40
. The side press wheel
63
is moved toward the mirror frame
40
such that the side edge of the mirror frame
40
is forced by the side press wheel
63
to curve inwards to form a curved edge
400
, as shown in FIG.
2
. Thereafter, the side press wheel
63
and the press wheel
61
are moved back to their original positions. In light of the curved edge
400
being located on the top of the locating wheel
62
, the locating wheel
62
must be moved inwards and away from the curved edge
400
before the locating wheel
62
is raised to return to its original position, thereby concluding the method for making integrally a mirror frame.
Such a prior art method as described above is no doubt capable of making integrally a vanity; nevertheless it has several shortcomings, which are described hereinafter.
The recovery of the position of the locating wheel
62
is time-consuming in view of the fact that the curved edge
400
is located on the top of the locating wheel
62
, as shown in FIG.
2
. As a result, before the position recovery of the locating wheel
62
is brought about, the locating wheel
62
must be moved inwards so as to be raised upwards to return to its original position. The drive structure of the locating wheel
62
is thus rather complicated.
The mirror or mirror frame is vulnerable to damage due to the speed differential of the upper rotary shaft
60
and the lower rotary shaft
50
. The upper rotary shaft
60
and the lower rotary shaft
50
are driven respectively by two independent motors. When these two motors operate at different speeds, the mirror frame
40
and the receiving seat
51
are in motion relative to each other. As a result, the mirror
41
or the mirror frame
40
is prone to damage.
As shown in
FIG. 3
, the curved edge
400
is disposed horizontally such that the surface contact can not be easily fixed. As a result, the mirror
41
is not firmly fixed with the mirror frame
40
.
The horizontal pleats of the curved edge
400
can inflict a wound on a person's fingers. As shown in
FIG. 3
, the pleats of the curved edge
400
are horizontally oriented, the fingers are especially susceptible to cut when the fingers inadvertently come in contact with the horizontally-oriented pleats of the curved edge
400
.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide a cost-effective method for making integrally a vanity.
It is another objective of the present invention to provide a damage-free method for making integrally a vanity.
It is still another objective of the present invention to provide a method for making integrally a vanity such that the mirror frame so made is provided with a curved edge capable of holding effectively the mirror and of minimizing the risk of the finger injuries by the curved edge.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a method comprising an initial step in which a mirror frame having a curved side is arranged in a rotary receiving seat such that the uncurved sides of the mirror frame are jutted out of the top edge of the rotary receiving seat. Thereafter, the mirror is pressed by a press disk in a direction toward the interior of the mirror frame. In the meantime, the mirror frame is provided on a side edge thereof with a rolling wheel perpendicular to the rotary receiving seat. The rolling wheel is provided in the wheel rim thereof with an arcuate groove. The mirror frame and the press disk are actuated by the rotary receiving seat to turn, thereby enabling the protruded edge of the mirror frame to be pressed slowly by the rolling wheel such that the protruded edge is provided with a curved edge which is formed by the arcuate groove of the rolling wheel, and that the mirror is fixed by point fastening. The rolling wheel and the press disk are then returned to their respective original position to conclude the method of the present invention.
The foregoing objectives, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
