Sign

Claim 1

An improved warning sign which may be quickly and easily mounted on and dismounted from a metal doorframe or the like in an institutional building, such as a hospital, for the purpose of alerting persons to temporary, potential hazards relating to maintenance work and the like begin done in the vicinity, the improved warning sign comprising: a base member having first and second, parallel, generally rectangular surfaces which are substantially flat and which are disposed back to back to each other and having integral, longitudinal, lateral edges which are disposed substantially perpendicular to the planes of the first and second surfaces and which project from the plane of the second surface, the first surface being adapted to face the metal doorframe and the second surface being adapted to face away from the metal doorframe when the sign is mounted on the metal doorframe; means for mounting the base member on the metal doorframe, the mounting means including a magnet which is secured to the first surface of the base member and which has a size and shape so that the magnet overlies substantially all of the first surface and so that when the first surface faces the metal doorframe, the magnet is adjacent to and in contact with the metal doorframe; an elongated, telescopable rod which has a first end and a second end and which is constructed so that its second end may be selectively moved longitudinally with respect to its first end so as to permit the length of the elongated, telescopable rod to be varied; a rod end holder integrally formed as a part of the base member, adjacent to one end of the base member, for selectivity receiving and holding the first end of the elongated, telescopable rod so that when the first end of the elongated, telescopable rod is being held by the rod end holder, the elongated, telescopable rod extends and projects from the second surface of the base member at a preselected, acute angle with respect to the second surface of the base member; a piece of material having a cautionary warning message thereon; and means for selectivity mounting the piece of material on the elongated, telescopable rod at a point between the first and second ends of the elongated, telescopable rod.
