Abstract: An assembly for supporting a device from a structural location exhibiting an upper horizontal edge. A main support body has front and rear faces, a bottom support ledge projecting from the front face and being adapted to receive a bottom extending edge of the device. A top support ledge extends from the rear face and is adapted to engage the upper horizontal edge of the structural location. A variant of the assembly incorporates a height adjustable component secured to the main support body and exhibiting a further ledge support location adapted to engage a top extending edge of the device. An angularly adjustable arm supporting component is secured to a lower rear face location of the main support body and is adjustable to establish a desired angle or tilt of the main support body and supported device.

Abstract: A device secured to an elevated location and in turn supporting an item such as a computer tablet. A hinged and foldable body has first and second pivotal sections each depicting a “U” shaped cross sectional profile and convertible between a collapsed/storage configuration and an extended/use configuration in which the sections establish a continuous and three sided support surface. A pair of suspending hooks extend upwardly from spaced apart locations along the body for engaging a vertical extending (seatback tray) support edge. Depth adjustable abutment portions located beneath the hooks establish proper angular orientation in use. Laterally adjustable and vertically extending brackets support vertical edges of the item placed upon the support surface.
