ABSTRACT:
A scissor-action carrier for suspending a sign or other display from an overhead inverted “U” shaped channel support track. The scissor-action carrier comprises an elongated first arm and an elongated second arm pivotally connected to one another at a pivot axis. A rotatable wheel is attached to an upper end of each elongated arm. Wherein the wheels are individually insertable into and removable from the “U” shaped channel. A connector means is arranged at a lower end of each arm to permit support of a sign or other display therefrom when the carrier is inserted within the support track and the connector means of each arm are in respective alignment with one another, wherein the arms are prevented from rotating freely and the wheels are kept inside of the support track when the carrier is supporting a sign or other display.
