CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of Australian Provisional Application No. 2023904066, filed Dec. 15, 2023, which is hereby incorporated by reference in their entirety.
TECHNICAL FIELD
The disclosure herein generally relates to a case for a tablet shaped device.
BACKGROUND
Examples of tablet shaped devices include but are not limited to a tablet computer, an APPLE IPAD PRO™, SAMSUNG GALAXY TAB™, and AMAZON FIRE™. Tablet shaped devices may have at least one port for connection to external devices and charging.
Some tablet shaped devices have only one port. For example, the current APPLE IPAD™ and SASMUNG GALAXY TAB™ each have a single USB-C port. Consequently, a charger plug connector and a headphone plug connector cannot by simultaneously received by these tablet shaped devices. Similarly, an external microphone plug connector and a keyboard plug connector cannot be simultaneously received. It may be desired, however, to simultaneously use multiple connectorized devices with a tablet shaped device with only one port.
Furthermore, it may be desired to extend the functionality of a tablet shaped device by connecting a peripheral to the port. Port connectors, however, are generally not sufficiently robust for day-to-day use, especially but not exclusively when the tablet shaped device is used in the field, an industrial environment. or a military environment, for example. Knocks and the like can break the connector, or disconnect the peripheral from the tablet shaped device.

DESCRIPTION OF EMBODIMENTS
FIG. 1 is an isometric view showing a tablet shaped device (“tablet”) in the form of an APPLE IPAD being received by an embodiment of a case for a tablet shaped device (“case”), respectively generally indicated by the numerals 1 and 10. FIG. 2 shows an isometric view showing the tablet 1 received by the case 10. The tablet 1 has a connector socket 2 in the form of a USB type-C connector socket. The case 10 comprises a peripheral device 12 in the form of a port expander. FIGS. 3 to 8 shows various views of the port expander 12 with the rest of the case 1 hidden. The port expander 12 comprises an inwardly orientated connector 14 in the form of a USB type-C plug for connecting to the connector socket 2 of the tablet shaped device 1. The port expander 12 comprises a plurality of outwardly orientated connectors 16, 18 in communication with the inwardly orientated connector 14. Connector 16 is in the form of a USB Type-C socket connector in electrical power communication with connector 14 for charging the tablet 1 via connector 14, and the connector 18 is in the form of a 3.5 mm headphone jack for audio electrical signal communication with connector 14, for connecting headphones and/or a microphone to the tablet 1 via connector 14. The connectors 16,18 may generally have any suitable and desired form for any suitable and desired form of electrical and/or signal communication. The peripheral device 12 comprises a housing 21 in the form of a housing assembly that protects the contents thereof. The housing assembly 21 is fixed together with at least one fastener in the form of a screw 35. Removing the at least one fastener 35 enables disassembly of the housing assembly 21, as shown in FIG. 9, which shows electronics in the form of a printed circuit board (PCB) housed in the housing 21 and to which are attached PCB mount connectors 14,16,18. The housing 21 defines a connector aperture for each of the connectors 14,16,18. As seen in FIG. 11, for example, the case 10 comprises a perimeter wall 20. The peripheral device 12 is mounted to the perimeter wall 20 and is housed at least in part therein. As understood with reference to FIGS. 1 and 2, for example, the peripheral device 12 is movably mounted to the perimeter wall 20. In FIG. 1, the peripheral device 12 is extended, and in FIG. 2 the peripheral device 12 is retracted. The peripheral device 12 can be moved with a sliding motion between the extended position shown in FIG. 1 and the retracted position shown in FIG. 2. Peripheral device 12 has a handle 31 defined by an arcuate cut-out or rebate at inwardly orientated surface 33. The handle 31 is at the outside of the back face 37. Peripheral device 12 also comprises an interiorly directed tongue 15 and outer curved surface 19 in keeping with the curved outer surface of the perimeter wall 20. A user can engage handle 31, for example with a finger-tip, to move the peripheral device 12.
The perimeter wall 20 defines a device receiving interior space 23 that generally has a complementary configuration to the tablet 1. The interior space 23 is backed by back wall 37 comprising inwardly orientated face 32 that is generally orientated to the tablet 1 when received and so the user. The perimeter wall 20 is configured to engagingly receive the tablet 1 within the interior space 23. The perimeter wall 20 comprises a resilient material, such as an elastomer, to enable resilient engagement with the tablet 1. The tablet 1 is received by a plurality of risers 30 in the form of riser tabs that separate the tablet 1 from the inside face 32 of the case 1. Tongue 15 extends into the interior space 23 beneath the tablet shaped device 1 when received. The tongue is intermediate two riser tabs 20.
To facilitate extension and retraction, the peripheral device 12 is slidably mounted to the perimeter wall 20. As seen in FIGS. 17 and 18, for example, the edge of the perimeter wall 20 defines a peripheral device receiving cavity 24 in the form of a peripheral device receiving aperture (elongated passageway or tunnel) that has outside opening (at an outer edge of the perimeter wall) and inside opening (at an inside edge of the perimeter wall). The device receiving cavity extends a minor portion of a side 52 of the perimeter wall 20. The perimeter wall defines at least one aperture 22, which in this embodiment are in the form of a plurality of slots 22. The plurality of slots 22 each have a longitudinal axis that is outwardly directed, the sidewalls of which act as linear motion guides. The at least one aperture is hidden behind a closure 13 which has been removed in FIG. 18. The aperture 22 may, however, generally take any suitable and desired form. The closure 13 and apertures 22 are on opposite sides of the case 10 to the back wall 37. The peripheral device 12 comprises at least one sliding slot insert 26 in the form of least one sliding anchor disposed in the at least one outwardly directed slot 22. In this but not necessarily all embodiments, the slot inserts 26 are captured within the slots 22. With reference to FIG. 7, the sliding anchor 26 comprises a body 27 in the form of a tab that is generally rectangular and a distal cap 29 attached to the body 27, the distal cap 29 being countersunk and disposed within another slot 25 defined by the perimeter wall 20 that is at slot 22's exterior side and wider than slot 22. The tab 27 is received within one of the apertures 22 and the cap 29 is configured to assist preventing the sliding anchor from being pulled through aperture 22 and consequently separation of the peripheral device 12 from the perimeter wall 20. Consequently, in this but not all embodiments the peripheral device 12 is inseparably mounted. The sliding anchor can generally take any suitable and desired form, for example the body 27 may take the form of a shaft. The sliding range of the sliding anchor is defined by the perimeter wall which is arranged therefore. The perimeter wall 20 can interfere with the sliding anchor 29 to stop its motion and so defines sliding limit stops 50 at the end of each of the slots 22. Protruding into slot 22 and intermediate the ends thereof are resilient stops 40 that are resiliently deformed by passage of the sliding anchors 26 therepast, and which can inwardly retain the sliding anchor. This may assist in the unwanted separation of the connector 14 from the device 1 and provide haptic feedback to the user.
The peripheral device 12 comprises generally any suitable electronics in communication with the ports. For example, in the present embodiment mounted to the PCB is a USB-C DAC integrated circuit (AL4042, for example) in signal communication with the inwardly directed plug connector 14, and which takes a digital audio signal from connector 14 and converts it into an analogue signal that is received by an amplifier integrated circuit (INA1620, for example) mounted to the PCB. The output of the amplifier is in signal communication with the headphone jack 18. Alternatively, the output of the DAC can be directly communicated to the headphone jack. The one or more integrated circuits may be powered by power drawn from the VBUS and GND pins of one of the USB ports. VBUS and GND pins of the USB Type-C ports 14,16 may be wired together to enable charging.
In alternative embodiments, the peripheral device 12 has alternative or additional functionality. For example:
- In an embodiment, the peripheral device 12 comprises a Radio Frequency Identification (RFID) reader in communication with the inwardly directed connector 14. The RFID reader may comprise, for example, a Texas Instruments TRF7964ARHBR IC RFID Reader operating at 13.56 MHZ mounted to the printed circuit board together with supporting electronics, or generally any suitable RFID integrated circuit. A user's credential information can be read information from a RFID card and software on the tablet shaped device can use the read credential information to control access to the tablet shaped device.
- In an embodiment, the peripheral device 12 comprises a location tracking device and/or a location tracking tag. This may, for example, provide location tracking in hazardous areas, for example heavy industrial sites.
- In an embodiment, the peripheral device comprises an optical scanner (for example a bar code or QR code optical scanner) in communication with the inwardly directed connector. The optical scanner can be used in a warehouse, for example. A user may be able to scan a code on a package and information on the package may be subsequently displayed on the tablet shaped device 1.
- In an embodiment, the peripheral device 12 comprises an alternative audio interface in communication with the inwardly directed connector 14. The audio interface may comprise a microphone port, an electric guitar port or generally any suitable and desired audio signal port. The audio interface may be used by a musician to, for example, record live music on the tablet shaped device.
