DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept while referring to the figures.
As illustrated in FIGS. 1 to 4, a tablet apparatus according to an embodiment of the present general inventive concept includes a first member 10 and a second member 20 which is formed in a shape corresponding to the first member 10 to cover an upper surface of the first member 10. In the present embodiment, the first and second members 10 and 20 have a rectangular plate shape.
The first member 10 includes a keyboard 11 which is provided on a portion of the upper surface thereof and allows a user to input a variety of commands and data as a user input to perform at least one of functions of the tablet apparatus, and a touch pad 12 to indicate and/or select at least one of the functions of the tablet apparatus, for example. A mouse (not illustrated) may be connected to the first member 10 to control the function of the tablet apparatus. The second member 20 includes a display portion 21, which is provided on an upper surface thereof to display one or more images and/or icons corresponding to the function of the tablet apparatus. The display portion 21 may include a touchscreen, and a user inputs commands or data as a user input through the display portion 21. A controller of the tablet apparatus disposed in at least one of the first member 10 and the second member 20 controls the display portion 21 to display at least one of an image, an icon, and a user interface corresponding to a function of the tablet apparatus. Accordingly, the second member 20 may cover the keyboard 11 provided on the upper surface of the first member 10.
When the first member 10 is disposed on the second member in a state illustrated in FIG. 1, the touch screen of the display portion 21 is exposed to an outside thereof. It is possible that one or more buttons including a power on/off switch of the tablet apparatus may be exposed to control the table apparatus or that one or more terminals connectable to a USB memory unit may also be exposed. The first member 10 and the second member 20 may be electrically connected to control the tablet apparatus. The first member 10 and the second member 20 may communicate with each other using a wireless communication method and/or a wired communication method. It is possible that the second member 20 may be operable independently from the first member 10. The tablet apparatus may have one or more power units or battery units to provide a power supply to the first member 10 and/or the second member 20. The power units or battery units may be disposed in the first member 10 and/or the second member 20 to perform the function of the tablet apparatus.
The first and second members 10 and 20 are connected to each other through one or more link members 30. Each of the link members 30 includes a first end positioned formed at one side thereof to be connected to a rear side of the upper surface of the first member 10 to be rotatable in a forward and rearward direction while being mounted, and a second end positioned at the other side opposite to the first end to be connected to a lower surface of the second member 20 to be rotatable in the forward and rearward direction. In the present embodiment, the link members 30 include a pair of link members 30, and both sides of the upper surface of the first member 10 and both sides of the lower surface of the second member 20 are respectively connected to each other through the two link members 30. The link member 30 may have a bar shape. The first member 10 may have a portion 10a having a width W1 and a height H to receive the link member 30 having a width W2 and a thickness D. The link member 30 may be disposed in a space corresponding to the portion 10a when the second member 20 is folded with the first member 10 as illustrated in FIG. 1.
As described above, when the first and second members 10 and 20 are connected through the two link members 30, the second member 20 moves from a first position in which the second member 20 covers the upper surface of the first member 10 as illustrated in FIG. 1, to any one of a second position in which the second member 20 is obliquely erected rearward and upward on the first member 10 as illustrated in FIG. 2, and a third position in which the second member 20 is obliquely erected rearward and upward from the rear side of the first member 10 as illustrated in FIG. 3, while being guided through the two link members 30 such that the second member 20 can rotate and/or move with respect to the first member 10.
In the first position, the second member 20 is arranged in parallel with the first member 10 to cover the upper surface of the first member 10. In this state, since the keyboard 11 and the touch pad 12 provided on the first member 10 are covered by the second member 20, a user inputs commands to the tablet apparatus through the display portion 21. Therefore, the tablet apparatus may be used in the same manner as a conventional tablet apparatus.
In the second position, the second member 20 rotates to be obliquely erected rearward and upward with respect to the first member 10, and thus a front end of the second member 20 is supported by the first member 10. In order for the second member 20 to be stably maintained in the second position, a support portion 13 is provided between the keyboard 11 and the touch pad 12 of the first member 10 such that a lower end (or the front end) of the erected second member 20 is caught by the support portion 13. In the state in which the second member 20 is in the second position, the tablet apparatus may be used for a video playback operation, as an electronic picture frame or the like. The support portion 13 is disposed between a surface of the keyboard 11 and a surface of the touch pad 12. That is, the support portion 13 has a portion raised from the surface of the keyboard 11 to the surface of the touch pad 12 by a height such that the second member 20 can be supported by the support portion 13 to be maintained the second position. The height of the support portion 13 may be higher than the thickness D of the link member 30 and/or the height H of the portion 10a of the first member 10.
In the third position, the lower surface of the second member 20 is supported by the link members 30 which are obliquely disposed rearward and upward thereof. Thus, similarly to the link members 30, the second member 20 is erected to be obliquely arranged rearward and upward. In the state in which the second member 20 is in the third position, since the keyboard 11 and the touch pad 12 provided on the first member 10 are exposed, a user inputs commands and data to the tablet apparatus through the keyboard 11 and the touch pad 12 in addition to the display portion 21. Therefore, the tablet apparatus may be used in the same manner as a notebook computer. The second member 20 may form a first angle with the first member 10 in the first position, a second angle in the second position, and a third angle in the third position.
As described above, the tablet apparatus according to an embodiment of the present general inventive concept may be utilized in various manners by moving the second member 20 provided with the display portion 21 through the link members 30 to various positions.
As illustrated in FIG. 4, one or more hinge units 40 are respectively disposed between the first and second members 10 and 20 and the two link members 30. Each of the hinge units 40 includes therein a cam (not illustrated), an elastic member (not illustrated) to elastically support the cam, and the like. The hinge unit 40 allows the associated link member 30 to maintain a state of rotating at a certain angle, so that the second member 20 may be maintained as it is in the first position, the second position, or the third position until an external force over a certain level is applied to the second member 20 with respect to the first member 10.
The first member 10 may have one or more receiving members 40a to receive the corresponding hinge units 40, and the second member 20 may have one or more receiving members 40b to receive the corresponding hinge units 40. The receiving members 40a of the first member 10 may have a recess portion to be coupled to at least a portion of the corresponding hinge unit 40. The receiving members 40b of the second member 20 may have a protrusion to be coupled to at least a portion of the corresponding hinge unit 40. A combination of the hinge units 40 and the receiving member 40a of the first member 10 may form a first rotating axis which is stationary, and a combination of the hinge units 40 and the receiving member 40b of the second member 20 may form a second rotating axis which is movable with respect to the first member 10.
The portion 10a of the first member 10 may have a length L1, and the link member 30 may have a length L2. The length L2 of the link member 30 may be shorter than the length L1 of the portion 10a of the first member 10 such that the portion 10a of the first member 10 accommodates the link member 30 when the first member 10 and the second member 20 are folded. The receiving members 40b of the second member 20 may be disposed at a portion spaced apart from a lower end of the second member 20 by a length L3. The length L3 may be shorter than the length L2 of the link member 30.
The receiving portion 40a may be disposed on a side portion of a first end of the link member 30, and the receiving portion 40b may be disposed in a center portion of a second end of the link member 30. However, the present general inventive concept is not limited thereto. It is possible that the hinge unit 40 is connected to the receiving member 40a and then connected to a center portion of the link member 30, and the hinge unit 40 is connected to the receiving member 40b and then connected to a side portion of the link member 30.
An end portion of the first member 10 connected to a first end of the link member 30 may be disposed away from a peripheral portion of the first member 10, and a middle portion of the second member 20 connected to a second end of the link member 30 disposed opposite to the first end may be disposed closer to a peripheral portion of the second member 20.
In the present embodiment, as illustrated in FIG. 5, the link member 30 is longer by a certain length t than one half of a width (length) W of each of the first and second members 10 and 20 in the forward and rearward direction thereof, and the second end of the link member 30 is rotatably mounted to a front side of the lower surface of the second member 20.
When the first and second members 10 and 20 are connected through the link member 30 having the above configuration, in the state in which the second member 20 is arranged in the third position as illustrated in FIG. 3, the second member 20 is erected to be spaced apart from a rear end of the first member 10 by a distance 2t of two times the certain length t, as illustrated in FIG. 6. Accordingly, the second member 20 is raised from the first member 10 in height so as to correspond to the spaced length 2t, and thus a user may more conveniently view the display portion 21 provided in the second member 20.
FIG. 5 illustrates the link member 30 to have a length which is longer than one half of the width (length) W of each of the first and second members 10 and 20 in the forward and rearward direction thereof and FIG. 6 illustrates the second member 20 to be raised in height in the state of being in the third position in the present embodiment. However, the present genera inventive concept is not limited thereto. For example, the link member has a length corresponding to one half of the width (length) of each of the first and second members in the forward and rearward direction thereof, and the second end of the link member is mounted to a central side of the second member in the forward and rearward direction thereof, so that the second member may come into contact with or be adjacent to the rear end of the first member. However, in this case, the tablet apparatus may be used by moving the second member to various positions. A user may be allowed to conveniently view the display portion provided in the second member by raising the height of the second member with respect to the first member 10 in the state in which the second member is in the third position as illustrated in FIGS. 3 and 6.
In addition, various modified embodiments may be realized. For example, the link member may have a length corresponding to one half of the width (length) of each of the first and second members in the forward and rearward direction thereof, the link member may be configured to be increased in length, or the second end of the link member may be movably mounted to the lower surface of the second member, so that the height of the second member provided with the display portion may be vertically adjusted.
Moreover, although the first and second members 10 and 20 are connected through the two link members 30 in the present embodiment, the present general inventive concept is not limited thereto. For example, the first and second members may be connected to each other through one link member having an H-shape. In addition, the first and second members may also be connected using a link member having various shapes.
As is apparent from the above description, a tablet apparatus according to an embodiment of the present general inventive concept may be utilized in various manners since a second member provided with a display portion moves to a first position in which the second member covers an upper surface of a first member, a second position in which the second member is erected on the first member, and a third position in which the second member is erected from a rear side of the first member.
In addition, in the tablet apparatus according to the embodiment of the present general inventive concept, since the second member is erected from the rear side of the first member in a state of being spaced apart from a rear end of the first member, the second member is raised in height such that a user may conveniently view the display portion provided in the second member.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
