发明名称 Sign
摘要 The improved sign disclosed herein is particularly adapted for use in an institutional building, such as a hospital, for warning persons of temporary, potential hazards relating to maintenance work and the like. The improved sign includes a base member which may be quickly and easily mounted on and dismounted from the metal doorframe normally found in such institutional buildings. The base member includes a magnet for mounting the sign on the metal doorframe and the like, and a rod end holder for receiving and holding one end of a telescoping, elongated rod that projects outwardly from the base member and thus, from the metal doorframe and the like. A piece of material is mounted on the other end of the elongated rod and includes a cautionary warning message.
