Detailed description of the embodiments
Hereinafter, the keyboard device for notebook computer according to the present invention will be explained in detail with reference to the drawings attached.
Fig. 1 is a perspective view showing a keyboard device for the notebook computer in accordance with the present invention, with the keyboard mounted in the mounting position of the main body, and Fig. 2 shows the keyboard moved to the operational position spaced away from the monitor portion.
As shown in the drawings, a notebook computer consists of a monitor portion 10 and a main body 20. The main body 20 has a keyboard device 30 mounted thereon. The keyboard device 30 is formed separately from the main body 20, and can move from the monitor portion 10, to the first operational position and to the second operational position. Fig. 3 is a broken perspective view of a keyboard device for notebook computer in accordance with the present invention. The keyboard device 30 is formed separately from the main body 20, and is connected to the main body 20 using a plurality of link arms 21. One end of the link arms 21 is rotatably mounted at the side surface of the keyboard 30 with a support pin 22, and the other end of the link arms 21 is rotatably mounted to the slide bar 24 of the main body 20 by the side surface of the main body 20(described later) with another support pin 23.
As described above, it is preferable that the two link arms 21 connecting the main body 20 and the keyboard 30 are mounted on both of right and left side surfaces, and the length of the link arms 21 of the monitor side is longer than that of link arm 21 of user's side so that the keyboard is slightly tilt down to the user when it is moved to the operational position. And it is preferable that a handle 25 is protruded laterally on the both upper peripheral parts of the keyboard 30 so that it is easy to grasp the keyboard 30 for moving the same.
Further, long slide grooves 26 are formed in the direction of the keyboard movement on the both sides of the main body 20, and the slide bar 24 is inserted into each slide groove 26 so as to be able to move along the slide groove. And a long guide slit 27 is formed in the slide bar 24 along the direction of the keyboard movement, and a guide pin 28 is fixed to the main body 20 through the guide slit 27. The first end part 27a of user's side of the guide slit 27 is slightly bent and tilted upwards, and the second end part 27b of the monitor side of the guide hole is slightly bent and tilted downwards.
According to the keyboard device with the such construction, as shown in Fig. 4(a), if the user lifts the keyboard 30 using the handle 25 in the state that the keyboard 30 is mounted on the mounting position of the main body 20, the keyboard 30 can be lifted from the main body 20 since the link arm 21 is rotated around the support pin 23 of the main body side as shown in Fig. 5(a). And then, if the user pulls the keyboard 30 in the direction far away from the monitor 10, the link arm 21 rotates further as shown in Fig. 5(b), and the end of user's side of the keyboard reaches to a surface of desk on which the notebook is as shown in Fig. 5(c) so that the keyboard 30 moves to the first operational position from the monitor portion 10. If the keyboard 30 moves to the first operational position, the distance between the monitor portion 10 and the user becomes larger so that the eye strain of the user can be reduced and the monitoring also becomes better. Also, since the length of the link arm 21 near the monitor portion 10 is larger than that of the link arm near the user, the keyboard 30 is slightly tilted so that the user can operate the keyboard 30 with ease. And in the state that the keyboard 30 is mounted on the mounting position, since the guide pin 28 fixed to the main body 20 is positioned and hinged in the first end 27a of the guide hole 27 formed in the slide bar 24, the slide bar 24 will not move when the keyboard 30 is pulled laterally.
As described above, if the keyboard 30 and the slide bar 24 are slightly lifted together in the state that the keyboard 30 is positioned in the first operational position in the Fig. 5(c), the guide pin 28 moves to the broken line part a, and the hinge-release starts from the first end part 27a so that the slide bar 24 can be moved.
Therefore, as shown in Fig. 6(a), the slide bar 24 attached to the keyboard 30 with the link arm 21 can be moved along the slide groove 26, and the keyboard 30 can be more retreated from the monitor portion 10. At the same time, since the slide bar 24 is slightly lifted from the main body 20 when the guide pin 28 is guided through the guide slit 27 as shown Fig. 6(a), the slide bar 24 and the main body 20 make less noise and wearing-out during the movement due to the contact each other will be reduced.
Then, if the keyboard 30 is more pulled as shown in the fig. 6(b), since the keyboard is moved into the second operational position further spaced away from the monitor portion 10, and in the second operational position, the distance between the monitor portion 10 and the user is further spaced away, an eye strain of the user can be reduced, and in particular, the monitoring can be performed well regardless of the large size monitor.
Also, the guide pin 28 that is fixed into the main body 20 is engaged and held into the second end 27b of the guide hole 27 in the second operational position to prevent the keyboard 30 and the slide bar 24 from being detached from the main body 20.
In the case of using the keyboard 30 in the second operational position and then returning it into the mounting position, a reverse order of operation moving from the mounting position to the second operational position as above mentioned is taken. That is, first, if the user slightly lifts up the keyboard 30 and the slide bar 24 of the user side, since the guide pin 28 is released from the second end 27b of the guide hole 27, the keyboard 30 and the slide bar 24 can be moved toward the monitor portion 10 and, as shown in the Fig. 5(c), if the slide bar 24 is completely moved within the main body 20, the guide pin 28 is engaged and held into the first end 27a of the guide hole 27.
4
Then, if the keyboard 30 is continuously pushed toward the monitor portion 10, since the link arm 21 is rotated around the supporting pin 23 of the main body 20, the keyboard is returned into an original mounting position as shown in Fig. 5(a).
Figs. 7(a) and 7(b) show a connection structure of the connection means for transmitting an electrical signal between the main body 20 and the keyboard 30, in moving the keyboard 30 from the mounting position to the second operational position by the keyboard device according to the present invention. As shown in Figs. 2, 3 and 7(a) and (b), a flexible substrate is used as the connection means, and the main body 20 is provided with a long insertion groove 31 into which the flexible substrate is inserted in a moving direction of the keyboard 30, wherein the insertion groove 31 is provided with two supporting bars 32, 33. The one end of the flexible printed wiring board 29 is connected with the associated connection parts (not shown) within the main body 20, and the other end is connected with the associated connection parts (not shown) within the keyboard 30. Further, the length of the flexible printed wiring board 29 is selected according to the moving distance of the keyboard 30, and the middle portion of the flexible printed wiring board 29 passes the two supporting bars 32, 33 which are mounted into the insertion hole 31, and the bottom surface of the keyboard 30 is formed with the supporter 34 through which the flexible substrate 29 passes, whereby, in moving the keyboard 30, it is preferable that it prevent the flexible substrate 29 from being damaged because of the contact or bumping into the peripheral parts.
According to such a constitution, even when the keyboard 30 is moved between the mounting position and the second operational position as shown in the Fig 7(a) and 7(b), since the flexible substrate 29 is always in an arranged state by the supporting bars 32, 33 and the supporter 34 without detachment, the flexible substrate does not contact with the peripheral parts so as to prevent damage and make it possible to perform the transmission function of the electrical signal between the main body 20 and the keyboard 30 without difficulty.
According to the keyboard device for notebook computer of the present invention as above mentioned, since the keyboard can be moved from the mounting position where the keyboard is mounted in the main body into the first and the second operational position spaced away in the direction far away from the monitor, it can particularly space a large sized monitor from the user in an optimal state, and reduce an eye strain of the user, and obtain a good monitoring.
