ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a cross type supporter mounting system for a notebook computer keyboard and the method for mounting the same, and especially to semi-auto cross type supporter mounting system for a notebook computer keyboard and the method of the same.
BACKGROUND OF THE INVENTION
Referring to
FIGS. 1 and 2
, the key of a computer keyboard is formed by a cap
11
, a touch moving elastomer
12
, a first supporter
13
, a second supporter
14
and a seat
15
. The center at each of two sides of the first supporter
13
is installed with a respective pivotal shaft
16
and a pivotal hole
17
so that the first supporter
13
and second supporter
14
are pivotally connected as a cross type linking structure. The touch moving elatomer
12
is installed between the cap
11
and the seat
15
and is positioned in the travelling path of the cap
11
. The lower ends of the two sides of the first supporter
13
and second supporter
14
are installed with respective pivotal shafts
18
and
19
pivotally connected to the through holes
20
,
21
preset on the seat
15
. The through holes
20
and
21
are installed with positioning pieces
22
and
23
, respectively for confining the pivotal shafts
18
and
19
to move upwards. Besides, a spacer
24
is further installed at a lateral side of the second supporter
14
. Thereby, as the first supporter
13
and second supporter
14
are placed into the through holes
20
and
21
, the first supporter
13
and second supporter
14
are prevented from sliding out.
In assembling such a key structure, the most complex structure is the assembly of the first supporter
13
and the second supporter
14
. In general, the operator needs to pivotally cross the first supporter
13
and second supporter
14
. Then, the pivotal shaft
18
below the first supporter
13
is installed in a respective through hole
20
. Then, an upper force is applied thereon so that the pivotal shaft
18
at the lower end of the second supporter
14
is pushed into a respective through hole
21
, and then a horizontal outer force is applied the cross structure formed by the first supporter
13
and the second supporter
14
so that the second supporter
14
is stopped by the spacer
24
so as not to slide out of the structure.
In this method, it is often that the pivotal shaft
19
at lower end of the second supporter
14
is deformed by outer forces due to an improper applied force. Furthermore, since the volumes of the first supporter
13
and second supporter
14
are too small, manual assembly is not economical. Therefore, in practical assembly, it will induce a great inconvenience.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a cross type supporter mounting system for a notebook computer keyboard and the method for mounting the same, and especially to semi-auto cross type supporter mounting system for a notebook computer keyboard and the method of the same. Therefore, the labor in the assembling process is reduced. Yield ratio is increased and the cost is decreased.
To achieve the objects, the present invention provides a cross type supporter mounting system for a notebook computer keyboard comprising: a first platform for placing a computer keyboard and movable along an approximate horizontal direction; a second platform movable along a vertical direction and being positioned above the first platform; and a press plate installed between the first platform and the second platform. Thereby, by the pressure of the machining table with the operation of a press plate having a special pattern and cylinders, the last two steps in the assembling process is automatized. Therefore, the labor in the assembling process is reduced. Yield ratio is increased and the cost is decreased.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
