  • FIG. 1 a an exploded view of a foldable computing device is shown configured with a flexible touch screen display 19 having four segments 11, 13, 15, and 17, which are partially enclosed within four respective end housings 21, 23, 25, and 27, that are also each supported at their back sides by four respective structural housings 53, 50, 47, and 52.
  • Each structural housing also supports plate mechanisms 41, 29, 45, and 33 that can slide between each flexible display segment to provide either locking and / or structural support so that the backing can remain in a rigid state when the devices is unfolded allowing the flexible display to have a flat support for when a user is interacting with its touch screen interface.
  • An actuating element 37 may also be utilized as a primary means for forcing each plate mechanism to slide in between the two structural housing and respective flexible display segments it is designated to provide support for.
  • This actuating element 37 may be rotated through a strut 40 that can be manually slid by the user of the device from an external point allowing the plate mechanisms to be slid into place all simultaneously.
  • Magnets 38 and 58 may also be integrated within each structural housing segment such that they can provide a means for locking the device in a folded state or an expanded state.
  • a rigid touch screen display 60 is also included in the assembly and contained within folded screen housing 63 which can hinge along the long edge of structural housing 52 which corresponds with segment 17 of flexible display 19.
  • a speaker 56 held within speaker housing 59 may also be included along the front side of rigid touch screen display.
  • the object of folded screen housing 63 and rigid touch screen display 60 and speaker 56 is to provide an additional module that can flip to the front or back side of the assembly allowing the device to be transformed into a phone state once the flexible touch screen display has been fully folded. This is further shown in FIGS. 24 a and 24 b. [0049] Similar to the embodiment shown in FIG. 1 a, the exemplary embodiment from FIG.
  • 1 b shows an exploded view of a foldable computing device configured with a flexible touch screen display 87 having two segments 80 and 81 situated opposite each other such that they can be folded flat against each other either face to face or back to back.
  • Flexible display segments 80 and 81 are also supported by structural housings 83 and 85, respectively, and sit above additional structural supports 93 and 92, respectively.
  • a single rigid touch screen display 96 is also included in the assembly and contained within folded screen housing 99 with a speaker 84 and speaker housing 70, all of which may be attached at the long edge of segment 80 of flexible display 87 such that it can rotate to the front side or the back side of the assembly depending on how the flexible display is folded, allowing the device to be transformed into a phone state.
  • the flexible touch screen display 87 is further supported by plate mechanism 75 which slides underneath flexible display 87 to provide structural support between segments 80 and 81.
  • This same plate mechanism 75 may also provide an alignment locking feature so that the two segments can be locked in an expanded state.
  • plate mechanism 75 is slid back to segment 80 underneath structural housing 83 and above structural support 93, the device can then be folded back to a phone state.
  • Slots 76 and 77 that sit within plate mechanism 75 engage with and slide along their respective posts which sit below on structural supports 92 and 93 and include posts 74 and 94.
  • Strut 72 acts as a mechanism that is manually operable by the user of the device to slide plate mechanism 75 in between segments 80 and 81 for structural support and locking.
  • Hinge components 89 and 91 which are attached between structural supports 92 and 93 provide a mechanism that allows flexible display segments 80 and 81 to be folded against each other. Magnets 64 and 66 may sit flat within structural supports 92 and 93 to provide a means for allowing the device to be locked in the folded state. Similarly, additional magnets may be included to attract and lock the two flexible display segments 80 and 81 when they are being situated in an expanded tablet state.

Abstract

L'invention concerne des dispositifs informatiques à écran tactile reconfigurables avec des configurations de pliage qui comprennent des dispositifs d'affichage souples et rigides qui sont constitués de segments qui peuvent être reconfigurés d'un état compact à un état déployé. Le facteur de forme de l'état compact est approximativement la taille d'un téléphone portable typique, avec un haut-parleur et un microphone intégrés. Le facteur de forme de l'état étendu est sensiblement la taille d'une tablette électronique qui peut également comprendre la fonctionnalité mécanique d'un ordinateur portable. Les deux états peuvent fournir une configuration qui comprend un dispositif d'affichage à écran tactile sur un côté avant et un boîtier de protection sur un côté arrière. Les dispositifs informatiques peuvent en outre comprendre des capteurs pour indiquer l'état de configuration et des mécanismes d'alignement, de verrouillage et de support structurel. Dans un mode de réalisation, un module fixé à au moins un segment, situé à l'intérieur d'au moins un segment ou autrement associé à au moins un segment peut contenir tout ou sensiblement tout traitement et mémoire, conjointement avec un système de communication, tous ceux-ci pouvant être utilisés dans l'un ou l'autre état.
