ABSTRACT:
A suspension hanger suspending a light weight point of purchase display in a manner that will permit swinging and turning of the display by slight air currents that are normally present in the surrounding atmosphere, and which will permit simple lowering of the display in the initial installation, or thereafter, to bring it to its desired height. The suspension consists of a vertical helical spring by which the display is suspended to permit oscillation of the display about a vertical axis, the spring being of a small diameter to permit swinging of the display, and being of a material of a low modulus of elasticity so that upon the exertion of a comparatively small pulling force in excess of the weight of the display the spring is stretched beyond its elastic.
