ABSTRACT:
An adjustable height desk including an open-front base and an outer skirting disposed over and around the base. Corner support brackets secured to the skirting below the work surface support threaded shafts. The lower end of each shaft is received and supported in a threaded nut positioned over hollow center channels formed in the support legs of the open-front base. The upper end of each shaft carries a sprocket that engages a continuous drive chain driven by a reversible motor. Selective activation of the motor moves the skirting, including the work surface, in a 21 inch range between the lowered seated position and the raised standing position.
