A Philadelphia judge has entered a nonsuit in a case involving an elevator mechanic who claimed he was injured when the protective flooring on a construction site slipped while he was moving an elevator door, causing the door to fall on him.

According to the plaintiff’s pretrial memorandum, plaintiff Darrin Ulmer was working as an elevator mechanic for ThyssenKrupp Elevator Corp. during the construction of the Comcast building in Philadelphia in 2007.
