ELECTROMAGNETIC DOOR HOLDER Abstract An adjustable door mounted armature for cooperating with a wall-mounted electromagnet and which provides for move- ment of the armature in substantially any direction. The arm- ature element includes an apertured flange; and a door mounted support plate includes a bifurcated portion with apertures. A pair of apertured bushings is employed, one on either side of the aperture in the flange, and each of the bushings has a gen- erally spherical outer configuration. The flange, and associ- ated bushings, are received between the bifurcated portions of the support plate with all apertures in alignment. A fastening bolt passes through the aligned apertures. By this means, the flange is supported between the bifurcated elements of the mount- ing plate to permit substantially unrestricted rotation of the flange in any direction relative to the support plate over at least a predetermined range of motion. The frictional resistance to movement of the armature element may be adjusted by the ten- sion in the fastening bolt which is tensioned so that the arma- ture will tend to retain the position to which it was last moved, thereby permitting adjustment of the armature element so that it will lie perfectly flush against the wall-mounted electromagnet.
