Electronic instrument with stand doubling as console cover

Claim 1

An electronic instrument having a cabinet, a front console with a plurality of input/output elements visible thereat, a flat cover/stand having a handle attached at one side and first and second arms integral with the cover/stand and extending from the other side thereof, a shaft axis extending through said cabinet and an elongated slot formed in a respective arm, said shaft axis passing through each said slot to permit pivotal and translational movement between said cabinet and said cover/stand about said shaft axis, wherein a part of the arm defining each said slot has a first region laterally adjacent a central part of the slot and second regions laterally adjacent flanking parts of the slot, the arm having a surface relief such that the first region is higher than the second regions thereby to form abutment surfaces, a shaft at each side of the cabinet aligned on said shaft axis and a knob mounted on each shaft, each knob having a shank portion, and means for movably biasing each knob along said shaft axis to produce a positive abutment between the shank portion of said each knob and the abutment surface of a respective slot such that said respective slot can be moved along said respective shank portion to position opposite sides of said respective central part to lock the cabinet, respectively, in a carriage position or an operating position such that, in the carriage position, the cover/stand is held against the console with a positive abutment existing between the knob shank portions and respective abutment surfaces on one side of said central parts to prevent movement of the cover/stand away from the cabinet when the instrument is lifted by the handle, and, in the operating position, the cover/stand is held away from the console and positioned to rest against an instrument supporting surface and to support the cabinet in an inclined position with a positive abutment existing between the knob shank portions and respective abutment surfaces on the opposite sides of said central parts to prevent movement of the cabinet towards the cover/stand.
