Title: Portable tripod support for portable keyboard device

Abstract: A portable tripod support beneath a portable notebook computer for a seated computer user. The support comprises a platform with spider-like foldable support arms having relatively folded parallel and unfolded flat coplanar positions. Fasteners on the ends of the unfolded arms are releasably secured to the computer near its corners. The platform is releasably connected to a head of an adjustable-height folding tripod with the platform plane tipped toward the user for optimum access to the computer's keyboard. One tripod leg is pointed toward the user to minimize interference between the tripod legs and the users feet when the support is positioned in front of a user seated as an aircraft passenger. Each tripod leg has an upper main leg member and at least another telescoping member for leg length adjustment. The tripod upper main leg members are pivotably connected to the head and their outward unfolding movement is limited by a foldable three-arm support having outer ends of the arms connected to the lower ends of respective main leg members. The inner ends of three arms are interconnected by a flat yoke member. Upper flat surfaces of the three arms and the yoke member are in a common horizontal plane providing a knee-height platform for user accessories. The arm and yoke member configuration prevents downward yoke movement relative to the platform plane, but permits upward yoke member movement enabling the folded spider arms and tripod legs to all be folded to parallel positions.
