Universal modular docking platform for portable device
An improved mounting platform (300) holds a variety of electronic devices (500, 510, 515) of differing sizes and shapes. A customized saddle assembly (310), designed for a particular electronic device, is affixed to the base (305) of the platform. The device is then inserted into the saddle and held securely in place by the top surface (905) of a cam assembly (315). Buttons (325, 326) and shuttle (925) control the raising and lowering of the cam. When the platform is in use, a spring (910) urges the cam against the back of the device being held. The device is released from the platform by squeezing the buttons together, causing the cam to move away from the device, and sliding the device out of the saddle. In an alternative embodiment, a pressure pad (1600) is used in place of the cam. A variety of electronic connections (335-375) and other accessories such as a loudspeaker (376) and a magnetic-stripe card reader (330) can be included in the platform in order to provide useful interfaces to the device.
This patent is based on an application that claims priority of provisional patent application Ser. No. 60/631,006, filed Nov. 24, 2004.
BACKGROUND—FIELD OF INVENTIONThis invention relates to mounting or docking platforms, in particular those used to contain and interact with portable devices such as personal digital assistants (PDAs), cell phones, global positioning system (GPS) receivers, and other hand-held devices.
BACKGROUND—NEED FOR PORTABLE-DOCKING PLATFORMSHand-held portable devices are used in a variety of circumstances—at a desk, in one's hand, and in moving vehicles, for example. When used by the driver of a moving vehicle, it is both convenient and much safer for the device to be rigidly mounted on the vehicle's dashboard or console, rather than held in the user's hand. Portable-device docking platforms also provide connections to external power sources and various accessories such as printers and wireless modems. These platforms may also include on-board audio amplifiers, speakers, magnetic card readers, bar-code scanners, and the like, that are not normally part of the device.
BACKGROUND—PRIOR ART—CELLULAR TELEPHONE CONNECTION DEVICEIn U.S. Pat. No. 5,535,274 (1996), Braitberg et al. teach a holder and connecting host device for use with cellular telephones. Base assemblies of various designs hold removable pocket adapters of various designs. Each pocket adapter is designed to hold a particular cellular telephone. The pocket adapter is held in place on the base assembly by a clip which mates with a latching assembly. The cellular telephone is held in the pocket adapter by a phone retainer latch 286 which secures the telephone in place in the adapter. Various electrical connections are facilitated between the cellular telephone, the base assembly, and the pocket adapter. Braitberg's holder and pocket adapters are designed for cellular telephone use only, and each separate pocket adapter must contain a custom phone retainer latch for each phone accommodated.
BACKGROUND—PRIOR ART—FIGS. 1 AND 2PDAs and other hand-held electronic devices are sold in a variety of shapes and sizes. Because of this, prior-art mounting platforms designed to hold one device were unsuitable for use with another device of a different size or shape. However some prior-art mounting platforms were able to hold devices comprising a range of sizes. However, these platforms suffered from various deficiencies, such as not securely gripping the device in the platform, not being custom-fit to the device, and being awkward to use. These deficiencies are especially important when the platform is mounted in a moving vehicle. Previous attempts at overcoming these deficiencies resulted in a large number of platform designs, each of which would rapidly become obsolete.
For example, in my U.S. Pat. No. 5,996,956 (1999), I teach a mounting platform for holding (docking) and interacting with various electronic devices, such as PDAs of the kind sold by Palm Computing of Mountain View, Calif., USA, and others. The platform secures the device to a convenient location in a vehicle, for example. The location can be the vehicle's windshield, dashboard, cigarette lighter socket, and the like.
The user interacts with the PDA by pressing the tip of a hand-held stylus against a touch screen at various predetermined locations. In the past, such devices normally required two hands to operate. Prior to my invention, one hand was required to hold the device, while the other hand manipulated the stylus. When my mounting platform is used to hold the device, the PDA can be operated by a single hand. This is especially useful when the device is to be used in a moving vehicle, for example.
A front view of the platform of my '956 patent in use is shown in
To remove PDA 2 from platform 6, the user pushes button 13, which lifts movable tabs 12 upward. This frees PDA 2 to rotate about an axis between fixed tabs 10 in a direction away from platform 6. PDA 2 is then lifted in a direction away from platform 6.
While this platform provides convenient and secure mounting for PDA 2, it can accommodate only PDA models with near-identical dimensions. PDAs which are thicker or thinner, or wider or narrower, require individually tailored platforms. This limits application of this platform to specific PDA models for which it is intended. Many PDAs of different sizes and shapes are produced by a number of manufacturers and their sizes and shapes are continually changing. Thus the present platform may not accommodate all models, including future models.
BACKGROUND—PRIOR-ARTA variety of mounting platforms, also called docks or cradles, are available from distributors such as Seidio, Inc. of Houston, Tex. USA, Arkon Resources, Inc. of Arcadia, CA, USA, National Products Inc., of Seattle, Wash., USA, Brodit AG, of Karlsborg, Sweden, Gomadic Corporation, of Herndon, Va., USA, and others.
These platforms suffer from one or more deficiencies, such as being designed to securely hold only a limited number of otherwise hand-held devices, being awkward to use, or failing to securely hold the device.
SUMMARYAn improved platform according to one aspect of my invention includes a base, a detachable saddle, a lever, buttons, and a movable restraining member so that when an electronic device is inserted into the saddle, the restraining member is activated by the lever, thereby securing the device to the base. Squeezing the buttons releases the device, allowing it to be removed from the base.
ADVANTAGESThe present invention may have one or more of the following advantages. In one aspect, one advantage is to provide a mounting platform that improves the ease of access to and use of an electronic device, especially one that facilitates single-handed use of the device. Another advantage of one or more aspects is to reduce the problem of obsolescence by providing a standardized base platform with a replaceable custom saddle that accommodates a variety of individual hand held devices comprising various sizes and shapes. These can include, but are not limited to, PDAs, cell phones, Global Positioning System (GPS) receivers, and the like. A further advantage of one or more aspects is to provide a clamping feature that is easily operated by one hand, thus reducing the amount of effort required to insert and remove a device from the mounting platform.
These mounting platforms may be held in a user's hand, attached in vehicles, or otherwise used for holding a PDA for viewing or for interacting with the PDA without the need to hold the PDA in the users hand. Common use of the platform is in the practice of law enforcement, transportation, field service and sales, as well as consumer use for GPS voice navigation, hands-free speakerphone interaction, amplified electronic audio file output, and other uses.
Other advantages and features of various aspects of the present invention will become apparent by a review of the specification, claims, and appended figures.

SUMMARY, RAMIFICATIONS, AND SCOPEThus it is seen that I have provided an improved universal docking platform for a portable device. A plurality of saddles, each uniquely adapted to the requirements of a particular device, are arranged to mount onto the same platform base with a common clamping means. Instead of a unique platform for each device, only the saddle is changed. In view of the constantly changing sizes and shapes of electronic devices, this results in considerable savings in design, tooling, and manufacturing costs, as well as reducing time to market.
While the above description contains many specificities, it will be apparent that the inventive system is not limited to these and can be practiced with the use of additional hardware and combinations of the various components described. For example, the platform is not limited to electronic devices but can be used to securely hold any portable device or article that can be accommodated by a custom saddle. The platform can be mounted on a surface or hand-held. Instead of or in addition to a magnetic card reader, an optical card reader, a bar-code reader, and the like can be included. Other features, such as an RFID (radio-frequency identification) circuit, a video camera, a disk drive, an extended power source battery, and an audio recorder can be included. Instead of providing two buttons for releasing the movable restraining element, a single button can be used. Instead of a coil spring, a leaf spring, torsion spring, extension spring, or another energy-storing member can be used. The materials, sizes, and shapes of the components can be varied from those shown and described.
Accordingly the full scope of the invention should be determined by the appended claims and their legal equivalents, rather than the examples given. Also, while the present system employs elements that are well known to those skilled in the art of mechanical engineering and hardware design, it combines these elements in a novel way, which produces a new result not heretofore discovered.
