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.

A support for musical keyboards comprising in combination: a trestle having a first end resting on the floor and a second end supporting a first musical keyboard, the second end of the trestle having at least one pair of spaced-apart transverse bars attached thereto, each transverse bar having a respective back end and a center line, the trestle being adjustble in height such that the musical keyboard may be adjusted to a desired height from the floor; a pair of upright shafts each having a first end and a second end, means for connecting the first end of each shaft to each respective back end of each transverse bar such that the upright shaft may pivot about the center line of the respective transverse bar and further such that rotation thereabout may be prevented; the second end of each shaft extending upwardly from each respective transverse bar; a pair of brackets, one bracket mounted perpendicularly to the second end of each respective shaft for support of a second musical keyboard and further such that when the shafts are pivoted about the center lines of the respective transverse bars, the brackets are moved together and apart with respect to one another such that keyboards of varying widths may be supported thereon; and a pair of additional brackets each having an upper arm and a lower arm, means for connecting the lower arm of each additional bracket near the second end of each respective upright shaft such that each additional bracket may pivot forwardly and backwardly about an axis which is perpendicular to the center line ofthe respective transverse bar and further such that rotation thereabout may be prevented, such that the upper arm of the additional brackets may support a third musical keyboard and when the additional brackets are pivoted about the connecting means, the third musical keyboard may be inclined.
