ABSTRACT:
FIELD OF THE INVENTION
The invention relates to input devices for portable electronic devices such as, but not limited to hand held computing devices. In particular, the invention relates to a miniature keyboard for a hand held computer device in which the keyboard is foldable to provide selective access to the keys. Further, the miniature keyboard may be configured as a separate accessory that is attachable to the hand held device or may be configured as an integrated input device.
BACKGROUND OF THE INVENTION
Hand held computing devices, “palmtops”, “palmhelds”, PDAs or hand held computers typically weigh less than a pound and fit in a pocket. These hand helds generally provide some combination of personal-information management, database functions, word processing and spreadsheets. Because of the small size and portability of hand held computers, strict adherence to hardware constraints, such as input device hardware constraints, must be maintained.
It is conventional to employ a touch pad or handwriting recognition area and/or device to provide input to the hand held computer. Because of the small size of hand held computers, data input in an efficient and ergonomic manner is often an issue. Accordingly, handwriting recognition areas and touch pads are used to facilitate such data input. Further, full size keyboards, which couple to the electronic serial connector of hand held computers, have been produced. Such full size keyboards may be configured to be separately foldable for storage and for portability.
Accordingly, there is a need for a miniature sized keyboard configured for use with a hand held computer that is couplable to the electrical connector of the hand held computer and which is configured to support the hand held computer such that relative movement between the hand held computer and the detachable keyboard are minimized. Further, there is a need for a miniature keyboard being configured of a size to be typed on with a single hand and providing good support to minimize movement between the keyboard device and the hand held computer. Further still, there is a need for a miniature keyboard having a keypad area that may be selectively concealed when the keypad is not being utilized without requiring detachment of the miniature keyboard assembly from the hand held computer. Yet, further still, there is a need for a miniature keyboard that may be integrated into the hand held computer.
The techniques herein below extend to those embodiments which fall within the scope of the appended claims, regardless of whether they accomplish one or more of the above mentioned needs.
SUMMARY OF THE INVENTION
An exemplary embodiment of the invention relates to an input device for a hand held computing device. The hand held computing (device includes a body, a display area, and an electrical connector. The input device includes a plurality of keys for providing input to the hand held computing device. The input device also includes a platform supporting the plurality of keys. The platform is configured to be sized for use by a single hand and the platform is selectively foldable to substantially conceal the plurality of keys from view. Further, the input device includes a support structure coupling the platform to the hand held computing device body. The support structure is configured to prevent substantial movement of the platform relative to the hand held computing device body.
Another exemplary embodiment of the invention relates to an input device for a palm held electronic information device. The electronic information device includes a body, a display area, and an electrical connector. The input device includes a plurality of keys for providing input to the electronic information device. The input device also includes a platform supporting the plurality of keys. The platform is configured to be sized for use by a single hand. The platform includes a hinge to selectively move the plurality of keys from a stowed position to a useable position. Further, the input device includes an interface configured to electrically couple the platform to the electronic information device. Further still, the input device includes a support structure coupling the platform to the electronic information device body, the support structure is configured to prevent substantial movement of the platform relative to the electronic information device body.
Yet another exemplary embodiment of the invention relates to a miniature keyboard for a palm held computer. The palm held computer including a body, a display area, and an electrical connector. The miniature keyboard includes a plurality of keys configured to provide input to the palm held computer. The miniature keyboard also includes a platform configured to support the plurality of keys. Further, the miniature keyboard includes a keyboard electrical connector configured to interface with the palm held computer electrical connector. Further still, the miniature keyboard includes a support structure coupling the platform to the palm held computer body.
Yet further still, the miniature keyboard includes a hinge coupled to the platform and configured to selectively move at least a portion of the plurality of keys to a stowed position from an accessible position. Yet further still, an exemplary embodiment of the invention relates to a miniature keyboard for a hand held computer. A miniature keyboard includes a plurality of keys configured to provide input to the hand held computer. The miniature keyboard also includes a platform configured to support at least some of the plurality of keys. Further, the miniature keyboard includes a support structure for the platform integrated into the hand held computer. Further still, the miniature keyboard includes a hinge coupled to the platform and configured to selectively allow movement of the platform from a stowed position to an accessible position.
