ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a notebook computer key, and especially to a key structure, thereby, the height of the key is reduced and the requirement of compact of modern products is met.
2. Description of the Prior Art
As shown in
FIG. 1
, the bridge type key
10
a
of a prior art notebook computer primarily includes a key hat
11
a
, an elastic touch moving piece
12
a
, a first supporting frame
13
a
, a second supporting frame
14
a
and a seat
16
a
. The first supporting frame
13
a
and second supporting frame
14
a
is crossed with one another. The pivotal shafts
18
a
and
19
a
at lower ends of the first supporting frame
13
a
and second supporting frame
14
a
are pivotally connected to the pivotal seats
20
a
and
21
a
protruded from the top of the seat
16
a
. The upper ends of the first supporting frame
13
and the second supporting frame
14
a
are connected to the key hat
11
a
. The two supporting frames are formed as a linkage. An elastic touch moving piece
12
a
is located in the traveling of the key hat
11
a
. The key hat
11
a
is guided by the two supporting frames
13
a
and
14
a
so that as it moves upwards and downwards, it will touch-press or leave from a soft circuit board
15
a
so that the switch will turn on or off. Such kind of design is disclosed in Taiwan Patent Nos. 237991 and 303971.
In the aforementioned prior art notebook computer key
10
a
, the pivotal shafts
18
a
and
19
a
at lower ends of the two supporting frames
13
a
and
14
a
are pivotally connected to the pivotal seats
20
a
and
21
a
protruded from the top end of the seat
16
a
. Therefore, the whole height of the key
10
a
will increase. This kind of design dose not conform the modern requirement of compactness.
SUMMARY OF THE INVENTION
A notebook computer key comprises a key hat, a seat, an elastic touch moving piece, a first supporting frame and a second supporting frame. The key hat is formed with an operating surface and an assembling surface at the top surface and the lower surface further. The seat is installed with a plurality of through holes, each through hole is installed with a positioning piece. The elastic touch moving piece installed between the key hat and the seat. The first supporting frame and second supporting frame installed between the assembling surface of the key hat and the seat. The two supporting frames are pivotally connected. The upper ends of the two supporting frames are connected to the assembling surface of the key hat, and each lower end of two sides of the two supporting frames are installed with a pivotal shaft for being pivotally connected to the through hole of the seat. The pivotal shaft at lower end of each side of the two supporting frames are protruded from the first lateral wall and the second lateral wall of the supporting frame. The pivotal shaft at each lower end of two sides of the two supporting frames is inserted into the through hole pivoted. Therefore, the height of the key is reduced and the requirement of compact of modern products.
The present invention will be better understood and its numerous objects and advantages will become apparent to those skilled in the art by referencing to the following drawings in which:
