JPH10222249A - Rocking and height adjusting mechanism for notebook computer - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve the security of the thin type computer and the operability of its key input by including a shaft part which has a rotary rocking mechanism and an L-shaped bracket which is coupled with the shaft part and tall enough to press the top surface of a display panel and can rotate from the top surface of the display panel to below the bottom surface of a main body. SOLUTION: This mechanism is constituted of the shaft part 2 having rotary rocking mechanisms fitted to the right and left of the rear part of the main body 10 and the L-shaped bracket 1 which is coupled with the shaft part 2 and tall enough to press the top surface of the display panel 20 and can rotate from the top surface of the display panel 20 to below the bottom surface of the main body 10. When the rotary lock mechanisms are unlock, the shaft 2 can rotate by 180 deg., so the L-shaped bracket 1 can be rotated from the position A shown by the solid line to the position C through the position B. When the L-shaped bracket 1 is at the position A, the display panel 20 is at a position where it can not be opened and when the L-shaped braket 1 is at the position C, the rear part of the main body 10 is lifted to slant the keyboard surface to a desk top 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lock / height adjusting mechanism for a notebook computer.

[0002]

2. Description of the Related Art When a notebook computer is inadvertently dropped while being carried, a display panel is easily opened in the middle of dropping, so that damage caused by a collision with a floor increases.

[0003] If a notebook computer is left on a desk carelessly, it may be used by others. In many cases, the power switch and floppy disk slot of a notebook computer are provided on the side, so if you do not want to operate them, special treatment is required, but the display panel integrated with the cover is closed. If it can be locked, the contents of the display cannot be seen and the keyboard cannot be touched, so that the use of others (by malicious or mischief) can be checked.

[0004] In a notebook computer, it is not preferable to provide a keyboard with an inclined portion, because the mounting efficiency and the storability of components (for example, putting in a bag or standing in a bookcase) are deteriorated. However, it is generally said that the keyboard surface has a slight inclination for better input efficiency and it is said that it is hard to get tired even if you work for a long time, so by lifting the entire bottom surface of the rear of the main unit, the keyboard surface A tilting mechanism has been proposed.

[0005] The prior art will be described in detail with reference to the drawings.

FIG. 5 is a side view showing the first prior art. The laptop computer illustrated in FIG. 5 includes an electronic device main body 110, a cover 116 having a display unit 114 on the back surface, and being attached to the electronic device main body 110 so as to be openable and closable.
And a dial key 113 for locking a hook claw 115 on the cover 116. (For example, see Japanese Utility Model Laid-Open No. 2-58821) FIG. 6 is a side view showing a second conventional technique. The laptop computer shown in FIG. 6 is provided with strip-shaped legs 251 that can be individually slidably pulled out on the left and right sides on the rear side of the main body 202. (See, for example, JP-A-8-22
FIG. 7 is a rear view showing a third conventional technique. The notebook computer shown in FIG.
1 is attached, and the leg 3 is rotatably supported on the support shaft 341.
By opening the opening 42 approximately 90 degrees, the leg 342 is connected to the main body 341.
And the main body 341 is inclined. (See, for example, JP-A-8-286796)

In the first technique described above, it is not necessary to have a key, but since the lock is large and the lock is housed inside the main body, it cannot be introduced into a notebook computer. Have difficulty.

In the above-mentioned second technique, the legs of the height adjustment device and the storage space thereof are required to be as small as possible in order to reduce the size of the device. However, the legs are thin and the strength is weak. It is easy to be apt to be formed, and play is easily generated in the folded part and the drawer.

The third technique described above is not preferable because if the thickness of the legs is too small, there is no force to support the weight of the main body, and the legs do not act as a leg. The structure in which the foot is opened right and left has a drawback that one leg is easily folded in response to an impact from the left or right.

The first technique is applied to the front part of the main body, and the second and third techniques are applied to the rear part of the main body. The cost / space problem remains if both are used simply. SUMMARY OF THE INVENTION It is an object of the present invention to provide a mechanism that can integrate the two and install them at the rear of the main body, and can solve the above-mentioned problems.

[0010]

According to a first aspect of the present invention, there is provided a lock and height adjustment mechanism for a notebook computer, comprising: a shaft having a rotation lock mechanism attached to the right and left rear portions of a main body; and a display panel connected to the shaft. And an L-shaped bracket having a height required to press the upper surface of the display panel and rotatable from the upper surface of the display panel to a position below the bottom surface of the main body.

According to a second aspect of the present invention, in the lock / height adjusting mechanism for a notebook computer according to the first aspect, the material of the L-shaped bracket is metal.

[0012]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 and FIG. 2 are a perspective view and a side view showing an embodiment of the present invention. The lock / height adjusting mechanism of the notebook computer shown in FIG. 1 has a shaft 2 having a rotation lock mechanism attached to the right and left rear portions of the main body 10, and is necessary for connecting to the shaft 2 and pressing the upper surface of the display panel 20. And an L-shaped bracket 1 having a height and rotatable from the upper surface of the display panel 20 to the lower portion of the bottom surface of the main body 10.

When the rotation lock mechanism is released, the shaft 2 can be rotated by 180 degrees. Therefore, the L-shaped bracket 1 is moved from the position A shown by the solid line in FIG. 2 to the position C shown by the dotted line in FIG. Can be rotated. When the L-shaped bracket 1 is at the position A, the display panel 20 cannot be opened, and when the L-shaped bracket 1 is at the position C, the rear part of the main body 10 is lifted and the keyboard surface is moved to the desk surface 3.
Tilt to zero.

FIG. 3 is a partially enlarged side view showing details of FIG. 2;
4A and 4B are partially enlarged sectional views showing details of FIG. The main body 10 and the display panel 20 have the depressions 4, and the L-shaped bracket 1 has projections 5 corresponding to the depressions 4. The shaft 2 is suspended from the main body 10 by a spring 3 so that the L-shaped bracket 1 can freely rotate (see FIG. 4A). When locking the rotation of the L-shaped bracket 1, the L-shaped bracket 1 is pushed in the direction of the arrow, and the shaft 2 is locked using a key with the upper body in which the projection 5 has entered the recess 4 (see FIG. 4B). ).

If the L-shaped bracket 1 is made of a metal such as iron or brass, the required strength can be obtained without increasing the thickness.

[0017]

The lock / height adjusting mechanism of the notebook computer according to the present invention is made compact by integrating the lock mechanism and the height adjusting mechanism, so that the security and key input workability of a thin computer can be improved. This has the effect.
