Thus, rotation of the drum serves to raise and lower the sign carrier and a sign carried by it. The sheaves on the carrier not only allow it to be raised and lowered, but also serve to make the unit self-balancing The user attaches a sign to the carrier when it is in its lowered position and then raises the sign and carrier to the ceiling. The motor, which is reversible, is remotely controlled either by wires leading between the motor and a switch or by radio control (with a control similar to that used on a garage door).Type: GrantFiled: June 23, 1998Date of Patent: March 16, 2004Assignees: Mechtronics CorporationInventors: Christopher S.
