Description:
FIELD OF THE INVENTION 
     The present invention relates to a tablet PC and its sustaining method used thereby. In particular, it refers to a tablet PC that exploits its battery device to sustain the computer core body. 
     BACKGROUND OF THE INVENTION 
     All average tablet PCs have handwriting tablets, allowing users to enter information. However, average tablet PCs are designed to lie prone on the desk surface. This design does not take into account that wrists would become sore easily after using the tablet PC for a long period of time. This problem evidently shows that this design of tablet PC lacks ergonomic consideration. Although conventional tablet PCs also have convertible keyboard, its full extension still requires an expansion of work space. These types of tablet PCs are far from being ideal. 
     Therefore, it is a high priority to improve the previously not considered ergonomic problem of the conventional tablet PC arising during information entry. After much experimentation, testing and research, the inventor has developed a new design for a tablet PC and its sustaining method used thereby. In addition to solving the drawbacks of the prior arts, this tablet PC also has the advantage of a more compact keyboard. This invention proposes to solve the problems arising from the prone placement of tablet PC unsuitable for entering information for a long period of time, and the cumbersome design of the convertible keyboard. Furthermore, it proposes to provide a solution for returning the computer to its original shape after being used at a slanted angle.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed. 
     Please refer to  FIG. 1  to  FIG. 3  showing a preferred embodiment of a tablet PC  10 . The tablet PC  10  includes a computer core body  11 , a battery device  12 , two front installation points  13  as shown in  FIG. 1 , and two rotating mechanisms  20  as shown in  FIG. 2 . In usual, each rotating mechanism  20  is made of an axle and a bearing. The two rotating mechanisms  20  are installed at the respective front installation points  13 , one on each side of the computer core body  11 , and they serve as links via which the battery device  12  is mounted onto the computer core body  11 . As shown in  FIG. 3 , the arrow (AR) indicates that rotating around the rotating mechanism  20  brings the battery device  12  from a combination position  30  to a sustaining position  31 . Thus, the battery device  12  serves as a stand to elevate and tilt the computer core body  11 . With this stand, users would be able to use a handwriting pen (not shown) to enter information for a long period of time on tablet PC  10 . In addition, the locations of front installation points might be varied according to the various demands. 
     Please refer to  FIG. 4 , which shows a preferred embodiment of a tablet PC  10 . As shown in  FIG. 4 , the computer core body  11  has a concave end  40  for accommodating the protruding ends  41  of battery device  12 . Inside each protruding end  41  is where each rotating mechanism  20  is located. At the support position  31  the battery device  12  also serves as a stand as shown in  FIG. 4  which elevates and tilts the tablet PC  10  to have θ degrees, making the use of the tablet PC more ergonomic. 
     Please refer to  FIG. 5 . The tablet PC  10  further includes two sliding concavities  50  located on computer core body  11 . The sliding concavities  50  provide tracks for sliding the display device  51  from a handwriting position  60  to an opened position  52 . In addition, this movement of display device  51  reveals a keyboard  53  (non-convertible). Referring back to  FIG. 2 , a concave surface  21  on battery device  12  allows such sliding movement of display device  51  beyond the edge of computer core boy  11 . Also shown in  FIG. 5  is the touchpad keyboard  53  that contains multiple raised keys  54  to assist the users&#39; orientations. The tablet PC  10  shown in  FIG. 6  is intended for mobile use without a supporting table surface. 
     From a technical point of view, the present invention is a tablet PC  10  that includes a computer core body  11 , a battery device  12 , which is placed in computer core body  11 , and rotating mechanisms  20 , which are installed at front installations points  13  in between the computer core body  11  and the battery device  12 . By rotating around the rotating mechanisms  20 , the battery device  12  moves from a combination position  30  to a sustaining position  31 , serving as a stand for elevating and tilting the computer core body  11 . Certainly, at present, the battery device  12  is mounted on the front installation point  13  of the computer core body  11 . In addition, it should be noted that the mounting locations of the installation points could be varied based on the different demands. 
     From another practical point of view, the present invention relates to a sustaining method for a tablet PC  10  that is applied to the computer core body  11 . At the front installation point  13  of computer core body  11 , a battery device  12  is installed. The sustaining method includes placing rotating mechanism at the front installation points in between the computer core body  11  and the battery device  12 . Rotation around rotating mechanisms  20  brings the battery device  12  from a combination position  30  to a sustaining position  31 . Thus, the battery device  12  is utilized within the sustaining method for a tablet PC  10 , acting as a stand to elevate and tilt the computer core body  11 . Certainly, this sustaining method further relates to the two sliding concavities  50  located on computer core body  11 . Sliding display device  51  along the sliding concavities  50  moves the display device  51  from the handwriting position  60  to an opened position  52 . As a result of such sliding movement, a keyboard  53  becomes available. 
     Viewing from another operational angle, the present invention relates to a tablet PC  10 , which includes a computer core body  11 , a battery device  12  installed at the front installation points  13  of computer core body  11 , and two sliding concavities  50  located on computer core body  11 . During the operation, the display device  51  could be moved from a handwriting position  60  to an opened position  52  via the sliding concavities  50 , and then the keyboard  53  would be as a result. Certainly, the computer also includes rotating mechanisms  20  installed at front installation points  13  in between computer core body  11  and battery device  12 . During operation, the battery device  12  could also be used as a stand to elevate and tilt the computer core body  11  when it is rotated around the rotating mechanisms  20  from the combination position  30  to the sustaining position  31 . 
     In view of the aforesaid discussions, the present invention is a novel design that utilizes a rotating mechanism installed at an installation point where the computer core body and battery device are linked to provide a method for using the battery device to elevate and tilt the computer core body. In addition, sliding concavities are installed on this computer core body. Sliding the display device along these sliding concavities from a handwriting position to an opened position would reveal the keyboard lying under the display device. 
     While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
