Abstract

A protective enclosure is disclosed for an interactive flat-panel control device. The protective enclosure is watertight, crush-resistant, and impact-resistant. An electrical adapter may disposed within the protective enclosure and covered with an elastomeric covering that permits a connector of the adapter to flex with respect to the lower shell of the enclosure so that the connector may easily be inserted into an interface jack of the electronic device. The elastomeric covering also provides a watertight seal that enables the protective enclosure to be submersibly watertight. While providing protection, the protective enclosure simultaneously allows smooth and accurate interaction with the interactive flat-panel controlled device. The protective enclosure has a protective membrane that permits RF and touch screen stylus inputs, as well as capacitance, such as from a finger, to be transmitted accurately to the flat-panel control. The hardness and texture of the protective membrane allows a stylus or finger to glide smoothly along the surface of the membrane without catching or sticking. The protective enclosure is further adapted to allow infrared and other communication signals while the device is secured inside the case. Further, electrical connections can be made through the case without affecting the protection afforded the electronic device inside. The protective enclosure may have a removable cable management belt clip that has a flange that retains and prevents entangling of an accessory cable for the interactive flat-panel control device.

Claims

1. A protective enclosure for a handheld electronic device having an interactive control panel comprising:

an upper shell and a lower shell that are hingedly connected, said upper shell and said lower shell enclosing said handheld electronic device, said handheld electronic device being a separate unit from said protective enclosure, said handheld electronic device being insertable in and removable from said enclosure by hand, said shell being substantially submersibly watertight when closed, said enclosure having at least one hinge pivot stop that constrains opening of said upper shell to a maximum predetermined angle;

a protective membrane connected to said upper shell, said membrane being sufficiently thin to permit smooth interactive tactile control of said control panel of said handheld electronic device;

an adapter disposed within said protective enclosure, said adapter having an internal connector that is capable of electrically connecting to said handheld electronic device, said adapter having an external connector that is capable of being electrically connected to an accessory for said handheld electronic device, said internal connector being electrically connected to said external connector so that when said accessory is electrically connected to said external connector said accessory is also electrically connected to said internal connector and to said handheld electronic device; and

an elastomeric covering that covers and substantially surrounds said internal connector and said external connector of said adapter, said elastomeric covering holding said internal connector and said external connector in place within said protective enclosure, said elastomeric covering permitting said internal connector to tilt within a predetermined range of angles so that said internal connector easily connects to said handheld electronic device when said handheld electronic device is inserted into said protective enclosure within said predetermined range of angles, said elastomeric covering maintaining said protective enclosure substantially submersibly watertight when said handheld electronic device is enclosed within said protective enclosure.

2. The protective enclosure of claim 1 further comprising:

a belt clip that attaches to a back side of said protective enclosure, said back side of said protective enclosure being opposite said protective membrane, said belt clip having a deflectable clip release that engages with a retainer that is connected to said back side of said protective enclosure so that when said clip release is not deflected said belt clip securely attaches to said protective enclosure, said belt clip being releasable from said enclosure by deflecting said clip release so that it disengages from said retainer, said belt clip having a flange around which a user may wind a cable of an accessory of said handheld electronic device around said belt clip, said flange retaining said cable close to said enclosure and preventing said cable from becoming entangled.

3. The enclosure of claim 2 wherein said enclosure has an elevated protective rim substantially surrounding a perimeter edge of said interactive flat-panel control.

4. The enclosure of claim 3 wherein said enclosure is made of a rigid material and wherein said enclosure substantially surrounds said handheld electronic device and wherein said enclosure is larger that said handheld electronic device so that said enclosure is crush-resistant and said enclosure substantially protects said handheld electronic device from breakage caused by crushing forces.

5. A protective enclosure for a handheld electronic device having an interactive control panel comprising:

at least two shell members that are hingedly connected, that enclose said handheld electronic device, said handheld electronic device being a separate unit from said protective enclosure, said handheld electronic device being insertable in and removable from said enclosure by hand, said shell members forming said protective enclosure and being substantially submersibly watertight when closed;

a protective membrane connected to at least one of said shell members, said membrane allowing tactile control of said control panel of said handheld electronic device;

an internal connector that connects to said handheld electronic device when said handheld device is inserted in said protective enclosure;

an external connector that connects to an accessory for said handheld electronic device and said internal connector so that said accessory can be connected to said handheld electronic device through said protective case; and

an elastomeric covering that covers and substantially surrounds said internal connector and said external connector, said elastomeric covering holding said internal connector and said external connector in place in said protective enclosure, said elastomeric covering permitting said internal connector to tilt within a predetermined range of angles so that said internal connector easily connects to said handheld electronic device when said handheld electronic device is inserted into said protective enclosure within said predetermined range of angles, said elastomeric covering maintaining said protective enclosure substantially submersibly watertight when said handheld electronic device is enclosed within said protective enclosure.
