Abstract: An adjustable portable stand, for supporting an elongate instrument (such as a guitar) by its base in a generally upright orientation, includes a multileg assembly including at least first and second vertically extending rigid legs disposed at a relative angle. First and second supports project outwardly from the first and second legs, respectively, for cooperatively supporting the base of an elongated instrument thereon, each of the supports being independently adjustable along the longitudinal axis of its respective leg and fixable at a selected point therealong. The supports are independently adjustable in height relative to the assembly to compensate for any bilateral asymmetry in the instrument base and thereby cooperatively maintain the instrument in a generally upright orientation.

Abstract: This invention concerns a trestle support for musical keyboards of the type equippd with legs crossed in the form of an `X`, equipped with a new device that permits rapid and easy adjustment of the angle of spread of the aforesaid legs and the height of the keyboard above the ground by means of a special new and original joint that allows for easy and quick mounting and detachment of transversal tubular bars positioned at either end of the legs of the trestle, those positioned at the base resting on the ground and acting as stabilizing feet for the trestle, while the ones positioned at the upper ends act as supporting arms for the keyboard.
