  • the housing parts 100, 200, 300 may be moveably connected to each other so as to allow for different mutual arrangements.
  • the first housing part 100 and the second housing part 200 are mutually connected by two hinges 400, which allows for relative pivotal motion. Accordingly, the first and second housing parts 100, 200 are arrangeable between a folded configuration wherein their front sides 102, 202 abut each other (see Figs. 3 and 4), and a configuration wherein they are positioned relative to each other much like the front and back cover of an open book.
  • the type and number of the connections between the first and second housing parts 100, 200 may vary for different embodiments.
  • a single, continuous hinge that runs an entire side of the first and second housing parts 100, 200 may be used, and instead of simple pivot hinges, more advanced hinges that allow for greater freedom of relative movement, e.g. ball-and-socket joint hinges, may be employed.
  • a connection between the first housing part 100 and the third housing part 300 may be partly provided for by a ball-and-socket joint 402.
  • a shaft that may be connected to the ball of the ball-and-socket joint 402 may be fixedly connected to (the back side 304 of) the third housing part 300, whereas the socket may be connected to the first housing part 100, preferably near a circumferential edge thereof.
  • the socket of the ball-and-socket joint 402 may itself be pivotally connected to first housing part 100 by a hinge 404.
  • a hinged ball-and-socket joint 402, 404 may enable great flexibility in positioning the third housing part 300 relative to the first housing part 100, which may be to the benefit of the portability of the wireless terminal 1, as will be explained below.
  • the connection between the first housing part 100 and the third housing part 300 may be partially provided for by means of a detachable hinge joint 410.
  • the hinge joint 410 may, for example, comprise a hinge pin, connected to one of the two housing parts and running along a side thereof. It may further comprise an elongate, cylindrical cup, connected to the other housing part, and provided with an axial slit through which the hinge pin can be inserted into and removed from the cup.
  • the hinge joint 410 may preferably be a little stiff, so as to provide enough friction for the two housing parts 100, 300 to be positioned securely in any mutual relation, such as the one shown in Fig. 4. Of course, the desired stiffness may also be incorporated in the pivot hinge 404/ball-and- socket joint 402 combination.
  • the back side 304 of the third housing part 300 may be provided with a connection bar 406 that is configured for cooperation with a connection bar clamp 408, which may be provided on the second housing part 200.
  • a connection bar clamp 408 which may be provided on the second housing part 200.
  • a portable wireless terminal 1 may typically comprise a battery for providing electrical power, a transceiver for enabling wireless functionality, and a data processing unit for performing more general tasks. In addition it may accommodate various peripheral units, such as one or more input, output and storage devices. The functionality of the terminal can thus easily be modified and/or extended.
  • the back side 104 of the first housing part 100 is provided with a keyboard part 108 configured to be operated by a left hand of an operator, while the back side 204 of the second housing part 200 is provided with a keyboard part 208 configured to be operated by a right hand of the operator.
  • Each keyboard part 108, 208 may correspond to about half of the layout of an ordinary desktop keyboard.
  • the front side 302 of the third housing part 300 is provided with a display 310, which may incorporate touch screen functionality.

  • the term 'keyboard part' intends to include any input device that is capable of registering keystrokes.
  • the term is therefore not to be construed narrowly as merely meaning a set of physical keys that can be pressed. Instead it also refers to, for example, touch screens that serve as a keyboard-like input device. Nevertheless, a real set of pressable keys is preferable in order to enable smooth touch typing.
  • the housing parts 100, 200, 300 of the portable wireless terminal 1 shown in Figs. 1-5 can be arranged in different configurations.
  • the terminal 1 When the terminal 1 is not in active use, and for example to be carried in a garment pocket or a bag, it may preferably be put in its folded configuration as shown in Fig. 3.

  • Fig. 5 merely represents an intermediate configuration
  • the configuration of Fig. 1 is the fully unfolded configuration that allows the terminal 1 to be used as a mini-laptop, featuring full and ergonomic keyboard functionality.
  • the two keyboard parts 108, 208 provided on the back sides 104, 204 of the first and second housing parts are intended to serve as a single, yet midway split keyboard.
  • the two keyboard parts face away from each other, and each of the keyboard parts includes an angle of about 90 degrees with a horizontal plane.
  • the rotational position of display 310 which is provided at a vertical level above the two housing parts 100, 200 to improve the readability thereof, may be adjusted by the operator to enable a comfortable working posture.
  • the terminal 1 When operating the terminal 1, a user faces the display 310 while his arms extend towards the keyboard parts 108, 208 in much the same way as when holding a book. Since the keyboard parts 108, 208 extend vertically, instead of horizontally as with conventional keyboards, the operator is not required to bend his forearms and wrists to operate them. This results in lower muscular activity in especially finger extensor muscles, which are sensitive to repetitive strain injuries, and in an improved overall comfort. The work configuration thus prevents an operator from having to assume a potentially harmful position that, in the long run, may lead to RSI complaints. Still, the split keyboard allows for ten-finger-typing, and thus prevents the loss of input productivity that is commonly associated with known portable wireless terminals. Furthermore, when a pointing stick 206 is provided, the operator may have mouse functionality at his thumbtip from the same ergonomic posture.
  • the front sides 102, 202 of the first and second housing parts 100, 200 may be provided with feedback representations of the keyboard parts present on their back sides 104, 204.

  • a feedback representation of a keyboard part 108, 208 may, for example, take the form of an LED- illuminated picture board.
  • Extra displays may contribute to the functionality of the terminal 1.
  • An extra display may, for example, facilitate multi-tasking such that, during a video-conference, a conversation partner can be shown on an extra display, while notes may be taken in an editor shown on display 310.
  • one or more of the extra displays provided on the front sides 102, 202 may be implemented as touch screens.
  • the touch screens would open up new input possibilities, and for example allow the terminal 1 to be used in different orientations. Relative to the orientation shown in Fig. 1, for example, the terminal 1 might be rotated over 90 degrees in a clockwise direction. In the thus-obtained position, a touch screen on the front side 202 could display a keyboard capable of accepting input.
  • the display provided on the front side 102 and display 310 could be used for any desired purpose.
  • Figs. 6-9 schematically illustrate a second exemplary embodiment of a portable wireless terminal 1 according to the present invention.
  • This second embodiment is similar to the first embodiment of Figs. 1-5, but designed to be extra sturdy.
  • each of the three housing parts 100, 200, 300 is permanently and directly connected to every other housing part.
  • the third housing part 300 may include a guide provision in the form of an elongate guide rail 416.
