Highly Secure Case for Disabled Patient

Hi all,

Posting this for a friend. Their family just purchased an iPad2 and the app Proloquo2go (communication software for those with difficulties). Does anyone have any suggestions for a very secure case? Function highly over fashion in this case is fine. They have an idea to use a rolling table for him and mount the iPad on a GPS-like mount so that it will be held up at eye level. A case would help if he were to accidentally knock it off the mount, or at night when it needs to be charged. Tried a few searches and wasn't able to find much information about this purpose.

Thanks!

Edit: Something like the Element Vapor or E13ctron type cases for iPhone would be great here, but I can't seem to find an iPad version.

 

Hmm, that looks promising Anyone else have any ideas?
