Definitions
- the present invention generally relates to a computer and other electronic devices. More specifically, the invention relates to portable computers having an adjustable display, multiple input devices, and multiple configurations.
- Portable computers or notebooks typically comprise of a computer base and a display screen.
- the computer base generally holds the central processing unit, memory, electronic circuitry and other components, such as a keyboard, a disk drive.
- the base is hinged to the display in a manner in which the display folds down on the base, as shown by the computer ( 900 ) in FIG. 5 .
- This design is referred to as the clam shell type enclosure.
- the display screen is typically connected to the base in such a way that the screen is hidden when the clam shell is closed. That is, the screen faces the upper side (typically, the keyboard) of the base.
- the screen and the keyboard are next to each other. If the screen is placed at a comfortable viewing position, it will make the arms and shoulders uncomfortable for typing. On the other hand, if the computer is placed at a comfortable typing position, it would make the neck uncomfortable when looking at the screen. This problem can cause serious computer-related work injuries.
- Another disadvantage is that it needs to sufficient room to fully open the clam shell computer and position the display screen at an angle of about ninety ( 900 ) or more with respect to the base for normal viewing; and this can be very difficult when operating in tight space, such as on the pull-out tray on the back of a declined airplane seat. Therefore, the clam shell design is insufficient for comfortable use.
- the purpose of the present invention is to support all configurations (1)-(6) in one single portable computer.
- the invention also has some additional features.
- the present invention supports, in one single portable computer, all configurations (1)-(6) as specified in the Background Section.
- a portable computer generally includes a computer base and a display, which are connected by one or more multi-sectioned arms. Electronic and electrical wiring runs inside the arms. There are pivots on both the computer base and the display for connections with the arms. The arm sections are linked together by flexible joints, which allow the attached sections to rotate or turn around them.
- the arms can be folded and positioned alongside the portable computer in closed positions. At the conventional screen viewing position, the arms can be turned away so that they do not block the computer base's edges for other uses, such as DVD and other outlets.
- the arms can also be flexibly stretched to allow continuous adjustment of the screen's spatial position by height (up or down relative to the base), depth (forward or backward relative to the base's user edge), and width (left or right away from space above the base). (See configurations (1) and (2) in the Background section.)
- a portable computer of the present invention allows such a mid-point to be position at any location in a 3-dimensional range with a diameter about the height of the fully stretched multi-sectioned arm.
- the arms are rotatably connected to the connection pivots on the base and the display, so that the base and display can rotate about the connection pivots. This way, the screen's viewing angle can be adjusted; furthermore, the portable computer can be set to various configurations (1)-(5) by arranging how the display and the base face each other.
- the arms can be detached completely from both the computer base and the display. This not only allows for the computer to be set for the desk note configuration (6), but also makes the arms replaceable (in case of damage, for example). Alternatively, all the configurations can be obtained by detaching the arms, rearranging the display and the base, and then re-attaching the arms (if necessary).
- Friction at the joints and the connection pivots keeps the arm sections, the base, and the display in their selected relative positions.
- the computer base has two sides and four edges: the keyboard side, the bottom side (opposite to the keyboard), the left edge, right edge, the front edge (user edge), and the back edge.
- the display also has two sides and four edges: the screen side, the back side (opposite to the screen), the left and right edges, and the upper and lower edges (from the user's point of view).
- one single multi-sectioned arm is connected to the back edges of the base and the display.
- two double-sectioned arms connect the base and the display by their side edges, with one on the left and the other on the right.
- the third embodiment is an extension of the second embodiment by replacing the two-sectioned side arms with side arms using combo-joints, thus enabling the display to move sideway.
- a bridge arm anchors on the left and right edges of the computer base, and in the middle of the bridge connects to the lower edge of the display.
- the fifth embodiment is an extension of the second embodiment by using triple-sections arms (just to show that it is possible to use side arms of more than two sections).
- a portable computer can switch to all configurations (1)-(6) just by relative rotation and turning of arm sections, the display, and the base.
- the portable computer can switch among some of the configurations by arm detachment and re-attachment.
- FIG. 1 is a list of notations used in the drawings to represent one of the sections in a multi-sectioned arm in various scenarios.
- FIG. 2 is a list of notations used in the drawings to represent a joint connecting two arm sections. They show how the attached arm sections can rotate relatively to the joint. (By relative, we mean that it can also been seen as the joint rotating while the arm section remain still.)

- FIG. 2 is a list of notations used in the drawings to represent a joint connecting two arm sections. They show how the attached arm sections can rotate relatively to the joint. (“relative” means that it can also been seen as the joint rotating while the arm section remain still.)
- FIG. 2A denotes a joint which allows the two attached sections to rotate around the joint; and they rotate on two parallel planes.
- FIG. 2B denotes a joint which allows the two attached sections to rotate around the same axis; and they rotate on the same plane.

- FIG. 2E is perspective view of a combination of two joints and three arm sections. The purpose is to show how simple joints can be combined to allow more flexible rotations of the end sections.
- arm section 831 can rotate in any selected plane; and the selected plane can change when arm section 832 turns (relative to arm section 833 ) around joint 842 . If we look at the combination as a whole, the end sections 831 and 833 can turn independently on separate planes. That is, even when arm section 833 stays still, arm section 831 can turn on its own on a selected plane; and furthermore, this selected plane can change even when section 833 does not move.
- FIG. 2F denotes a joint which allows the two attached sections to rotate independently around two separate axes, and they rotate on two separate planes. There is more than one variation (two being shown here). The point of view dictates which variation to use in a drawing.
- this type of joint is marked by a block circle containing two of the three symbols: a white vertical bar, a white horizontal bar, and a white circle, which are used to indicate the planes for the associated arm sections to rotate on.
- FIG. 4A is a perspective view of the display of a portable computer in an upward position.
- Display 90 generally has two sides and four edges: viewing screen side 98 , back side 97 , upper edge 91 , lower edge 92 , left edge 93 , and right edge 94 (from the user's normal view point).
- FIG. 4B is a perspective view of the base of a portable computer.
- Base 80 preferably includes a central processing unit and other electronic components and a data entry member, such as a keyboard.
- Base 80 generally has two sides and four edges: upper side (keyboard) 87 , bottom side 88 , front or user edge 81 , back edge 82 , left edge 83 , and right edge 84 (from the user's normal view point).
- the bottom side 88 can sometimes be used by an alternative data entry member, such as stylus input.
- FIGS. 6 to 17 show a portable computer ( 100 ) according to a first embodiment of the present invention.
- Computer 100 has one single back arm.
- FIG. 6A is a perspective view of the portable computer ( 100 ) of the first embodiment of the present invention.
- This embodiment includes a display 90 , a base 80 , and a multi-sectioned arm 130 .
- One end section 131 of the arm is connected to the display at pivot 151 ; and the other end section 134 is connected to the based at pivot 152 .
- Pivot 151 allows the display to rotate relatively around arm section 131 ; and pivot 152 allows the base to rotate relatively to arm section 134 . Consequently the portable computer can be arranged into various configurations by controlling how display 90 and base 80 face each other.
- Arm sections 132 and 133 can be adjusted independently around joint 143 , as assisted by joint 142 and joint 144 (a function denoted as a white circle in the black circle), respectively. Together they allow the arm to control the continuous movement of pivot 151 (and thus the screen) within a selected plane. Besides, this selected plane can be changed continuously using a function of joint 141 (denoted as a horizontal white bar inside the black circle), together with its counterpart in joint 144 .
- the viewing screen's position can be adjusted continuously within a three dimensional space of semi-diameter equal to the total length of arm sections 132 and 133 .
- the screen's viewing angle can be adjusted using the other function of joint 141 (denoted as a vertical white bar).
- joint 141 denoted as a vertical white bar.
- FIG. 6B is the top portion the arm connected to the display of computer 100 . This portion can be substituted by an alternative version as shown in FIG. 6C .
- One function of joint 141 (as in FIG. 6B ) is to tilt the screen for different viewing angle; and this can be achieved by turning display 90 at the “T-shaped” arm section 138 (as in FIG. 6C ).
- the ability for the display to turn around the end section 131 (as in FIG. 6B ) can be achieved by turning the “T-shared” arm section at joint 147 (as in FIG. 6C ).
- joint 142 in assisting the arm section 132 to turn (as in FIG.
- joint 148 can be achieved by a function of joint 148 (denoted as a white circle in the black circle, as in FIG. 6C ).
- one function of joint 141 as denoted by the horizontal white bar inside the black circle (as in FIG. 6B ) can be achieved by the counterpart in joint 148 (as in FIG. 6C ).

- FIG. 9 is a perspective view of computer 100 in a conventionally opened, screen-up position, with the folded arm placed next to the display's left back edge 82 (from the user's point of view). This position can be obtained from by swinging the arm sections simultaneously around 141 and 144 (using the functions denoted by the horizontal white bars inside the black circles) in FIG. 8
- FIG. 10 is a perspective view of computer 100 in a conventionally opened, screen-up position, with the folded arm placed away from the display's back edge 82 (to avoid blocking the back edge 82 of the base for other uses, such as various cable outlets.)
- This position can be obtained from by swinging the arm simultaneously using the functions denoted by the horizontal white bars in 141 and 144 in FIG. 8 .
- FIG. 11 is a perspective view of computer 100 in a position where the display is up-lifted, screen facing the user, and the arm being away from the back edge 82 of the base. This position can be obtained by opening up arm 130 in FIG. 10 .
- FIG. 12 is a perspective left side view of computer 100 in an opened, screen-up position, where the screen is away from its conventional vertical position towards the user. This position can be obtained by adjusting the rotation angles of 132 and 133 at joint 143 in FIG. 11 .
- FIG. 13 is a perspective view of computer 100 in an opened, screen-up position, where arm sections 132 and 133 are positioned near the back edge 82 of the base. This position can be obtained by lifting the end section 131 around joint 141 in FIG. 6A .
- FIG. 14 is a perspective view of computer 100 in an opened, screen-up and backward facing position, where arm sections 132 and 133 are positioned near the back edge 82 of the base. This position can be obtained from FIG. 8 by turning the screen to the back.
- FIG. 15 is a perspective view of computer 100 in a closed position with viewing screen 98 facing upward (for the tablet PC configuration). This position can be obtained by closing down the display from FIG. 14 .
- FIG. 16 is a perspective view of computer 100 in an open position in which the viewing screen 98 is facing the front, and the whole display is lifted and positioned towards to the right side of the user (suitable for view sharing.) This position can be obtained by moving display 90 towards the right side of the user in FIG. 13 .
- FIG. 17 is a perspective view of computer 100 in a closed position with the base sitting on top of the display (for the space-saving configuration). This position can be obtained by from FIG. 13 in the following steps: Rotate base 180 around arm section 134 (connected at pivot 152 ) to let the keyboard face down; close the computer; and turn the computer down-side-up.
- FIGS. 18 to 27 show a portable computer ( 200 ) of a second embodiment of the present invention.
- Computer 200 has two double-sectioned side arms.
- FIG. 18A is a perspective view of the portable computer ( 200 ) of the second embodiment of the invention.
- the computer has two double-sectioned side arms. It is in a position where the screen is lifted and facing the user.

Abstract
A portable computer is comprised of a base, a display, and one or more multi-sectioned arms connecting the base and the display. The arms can be folded and parked alongside the computer in a closed position. The arms can also be detached from both the base and the display. The display's viewing position can be continuously adjusted up, down, forward, backward, left, or right relative to the base, in a 3-dimensional range of movement with a semi-diameter of the height of the fully stretched arm. The base and the display are rotatably connected to the arms, so that the base and the display can rotate independently around the connections to control how they face each other, enabling multiple configurations in one computer. Five embodiments of the present invention are presented for illustration, based on arm designs and how they are connected to the base and the display.
Description
- The present invention generally relates to a computer and other electronic devices. More specifically, the invention relates to portable computers having an adjustable display, multiple input devices, and multiple configurations.
- Technological advancements have enabled portable computers to be built in various forms such as notebook, tablet PC, and personal digital assistants (PDA). Some of these forms can be unified into one single portable computer with multiple configurations.
- Portable computers or notebooks typically comprise of a computer base and a display screen. The computer base generally holds the central processing unit, memory, electronic circuitry and other components, such as a keyboard, a disk drive. Typically, the base is hinged to the display in a manner in which the display folds down on the base, as shown by the computer (900) in
FIG. 5 . This design is referred to as the clam shell type enclosure. The display screen is typically connected to the base in such a way that the screen is hidden when the clam shell is closed. That is, the screen faces the upper side (typically, the keyboard) of the base. - There are several disadvantages of the clam shell design. One disadvantage is that the screen and the keyboard are next to each other. If the screen is placed at a comfortable viewing position, it will make the arms and shoulders uncomfortable for typing. On the other hand, if the computer is placed at a comfortable typing position, it would make the neck uncomfortable when looking at the screen. This problem can cause serious computer-related work injuries. Another disadvantage is that it needs to sufficient room to fully open the clam shell computer and position the display screen at an angle of about ninety (900) or more with respect to the base for normal viewing; and this can be very difficult when operating in tight space, such as on the pull-out tray on the back of a declined airplane seat. Therefore, the clam shell design is insufficient for comfortable use.
- In general, it is useful to be able to arrange a single portable computer into various configurations as follows.
-
- (1) Improved Notebook configuration: The display screen can be adjusted to a desirable viewing angle, and to a position by height (up or down relative to the base) and by depth (forward or backward relative to the base's user edge).
- (2) Shared viewing configuration: This is configuration (1) plus display adjustment by width (left or right of the space above the keyboard). (This can be useful when more than one people are looking at the screen at the same time.)
- (3) Tablet PC configuration: The portable computer is closed with the base stacked underneath the upward-facing screen to be used as input pad. (The keyboard in this configuration can either be facing down or up. But it does not matter.)
- (4) Stylus input configuration: The portable computer is open with screen up in normal viewing position; but the bottom side (opposite to the keyboard) of the base is up and used as input pad.
- (5) Space saving configuration: The portable computer is closed with the display stacked underneath the base, so that the base can be used as a desktop machine together with a desktop display unit, typically with a bigger and better screen.
- (6) Desk note configuration: The display is completely detached from the base so that the base can be used as a desktop machine together with a desktop display unit. (Both this configuration and the Space saving configuration can get the built-in display out of the way of the desktop monitor screen.)
- There have been numerous attempts to address various subsets these six configurations. Many of them are focused on the screen viewing position adjustment using various approaches, which are all different from the multi-sectioned arm approach in the present invention. Some others are focused on mode transitioning between conventional notebook and tablet PC. There has been no single invention until now that can solve all six configurations in a single computer.
- The purpose of the present invention is to support all configurations (1)-(6) in one single portable computer. The invention also has some additional features.
- The present invention supports, in one single portable computer, all configurations (1)-(6) as specified in the Background Section.
- A portable computer according to the present invention generally includes a computer base and a display, which are connected by one or more multi-sectioned arms. Electronic and electrical wiring runs inside the arms. There are pivots on both the computer base and the display for connections with the arms. The arm sections are linked together by flexible joints, which allow the attached sections to rotate or turn around them.
- The arms can be folded and positioned alongside the portable computer in closed positions. At the conventional screen viewing position, the arms can be turned away so that they do not block the computer base's edges for other uses, such as DVD and other outlets.
- The arms can also be flexibly stretched to allow continuous adjustment of the screen's spatial position by height (up or down relative to the base), depth (forward or backward relative to the base's user edge), and width (left or right away from space above the base). (See configurations (1) and (2) in the Background section.)
- To see the range of screen position adjustment, consider the middle point at the lower edge of the display. In the conventional clam shell enclosure design (as shown in
FIG. 5 ), this mid-point travels along a pre-determined curve with a semi-diameter about the height of the hinge connection between the base and the display. In contrast, a portable computer of the present invention allows such a mid-point to be position at any location in a 3-dimensional range with a diameter about the height of the fully stretched multi-sectioned arm. - The arms are rotatably connected to the connection pivots on the base and the display, so that the base and display can rotate about the connection pivots. This way, the screen's viewing angle can be adjusted; furthermore, the portable computer can be set to various configurations (1)-(5) by arranging how the display and the base face each other. The arms can be detached completely from both the computer base and the display. This not only allows for the computer to be set for the desk note configuration (6), but also makes the arms replaceable (in case of damage, for example). Alternatively, all the configurations can be obtained by detaching the arms, rearranging the display and the base, and then re-attaching the arms (if necessary).
- Friction at the joints and the connection pivots keeps the arm sections, the base, and the display in their selected relative positions. There are (optional) locks at the joints and connection pivots to keep arm sections, the base, and the display from leaving their chosen relative positions. There are mechanisms at the joints and the connection pivots to limit how much the attached arm sections can rotate or turn. (This can prevent potential wiring and other damages from unlimited rotating and turning.) There are also locks to prevent the connecting arms from unintentional detachment from the connection pivots.
- Five different embodiments of the invention are presented, based on the number of arms and sections in each arm in the designs as well as how the arms are connected to the computer base and the display.
- The computer base has two sides and four edges: the keyboard side, the bottom side (opposite to the keyboard), the left edge, right edge, the front edge (user edge), and the back edge. The display also has two sides and four edges: the screen side, the back side (opposite to the screen), the left and right edges, and the upper and lower edges (from the user's point of view).
- In the first embodiment, one single multi-sectioned arm is connected to the back edges of the base and the display. In the second embodiment, two double-sectioned arms connect the base and the display by their side edges, with one on the left and the other on the right. The third embodiment is an extension of the second embodiment by replacing the two-sectioned side arms with side arms using combo-joints, thus enabling the display to move sideway. In the fourth embodiment, a bridge arm anchors on the left and right edges of the computer base, and in the middle of the bridge connects to the lower edge of the display. The fifth embodiment is an extension of the second embodiment by using triple-sections arms (just to show that it is possible to use side arms of more than two sections).
- In summary, a portable computer according to the present invention can switch to all configurations (1)-(6) just by relative rotation and turning of arm sections, the display, and the base. Alternatively, the portable computer can switch among some of the configurations by arm detachment and re-attachment.

-
FIG. 2 is a list of notations used in the drawings to represent a joint connecting two arm sections. They show how the attached arm sections can rotate relatively to the joint. (“relative” means that it can also been seen as the joint rotating while the arm section remain still.) -
FIG. 2A denotes a joint which allows the two attached sections to rotate around the joint; and they rotate on two parallel planes. -
FIG. 2B denotes a joint which allows the two attached sections to rotate around the same axis; and they rotate on the same plane. -
FIG. 2C denotes a joint which allows the two attached sections to independently rotate around the joint on a common plane; and the sections will not overlap in a folded position. (The point of view dictates which one of the two pictures to use in the drawings.) -
FIG. 2D denotes a joint which allows the two attached sections to turn independently in relatively opposite direction. -
FIG. 2E is perspective view of a combination of two joints and three arm sections. The purpose is to show how simple joints can be combined to allow more flexible rotations of the end sections. Around joint 841,arm section 831 can rotate in any selected plane; and the selected plane can change whenarm section 832 turns (relative to arm section 833) aroundjoint 842. If we look at the combination as a whole, theend sections arm section 833 stays still,arm section 831 can turn on its own on a selected plane; and furthermore, this selected plane can change even whensection 833 does not move. (In engineering implementation, if themiddle section 832 is short, it may help to think of such a joint combination as just one combo-joint mechanism which allows the two attachedend sections FIG. 2F .) -
FIG. 2F denotes a joint which allows the two attached sections to rotate independently around two separate axes, and they rotate on two separate planes. There is more than one variation (two being shown here). The point of view dictates which variation to use in a drawing. In general, this type of joint is marked by a block circle containing two of the three symbols: a white vertical bar, a white horizontal bar, and a white circle, which are used to indicate the planes for the associated arm sections to rotate on. We generally use the white horizontal bar to indicate the associated arm section that can rotate on a plane parallel to the base of the portable computer. We use the white vertical bar to indicate the associated arm section that can rotate on a plane that is perpendicular to the base of the computer, and that the plane is invisible or reduced to a line from the perspective view point of the drawing. And we the white circle to indicate the plane that is also perpendicular to the base of the computer, but the plane is at least partially visible from the perspective view point of the drawing. (This notation is somewhat analogous to the 3D coordinates. But it is not the same because the three planes here do not have to be perpendicular to one another. In engineering implementation, this type of joint can be substituted with a joint-combo such asFIG. 2E .) -
FIG. 4A is a perspective view of the display of a portable computer in an upward position.Display 90 generally has two sides and four edges: viewingscreen side 98, backside 97,upper edge 91,lower edge 92, leftedge 93, and right edge 94 (from the user's normal view point). -
FIG. 4B is a perspective view of the base of a portable computer.Base 80 preferably includes a central processing unit and other electronic components and a data entry member, such as a keyboard.Base 80 generally has two sides and four edges: upper side (keyboard) 87,bottom side 88, front oruser edge 81, backedge 82, leftedge 83, and right edge 84 (from the user's normal view point). Thebottom side 88 can sometimes be used by an alternative data entry member, such as stylus input. - FIGS. 6 to 17 show a portable computer (100) according to a first embodiment of the present invention.
