Friction-mountable hanger

DETAILED DESCRIPTION OF THE INVENTION The single mounting arm hanger of the invention will be described first with reference to FIGS.
1, 3, and 4.
It is important to recognize that the hangers of the invention are formed by extrusion of plastics.
As such, they have what is called an extrusion profile, that is, a profile defined by the die of extrusion.
The profile defines various parts of the hanger.
Because some parts of the hanger are formed to be relatively stiff and others are formed to be relatively resilient and deformable but recoverable from deformation, formation of the hanger is by way of co-extrusion of plastic materials of different properties through an extrusion die.
In this manner, the different parts of the hanger are fused together (as they are formed) into an integrated unitary whole.
The extrusion profile of the single arm hanger 10 of FIGS.
1 and 4 has a stiff hook 12 at the lower end of a stiff depending leg 14.
A stiff cantilevered mounting arm 20 extends from an upper base part 22 on the hook leg 14 to the outer end or tip 24 of the cantilevered arm.
The extrusion profile thickness of the cantilevered arm and hook are illustrated to be about substantially equal, although some variation of thickness may be employed, as will be discussed.
A substantially uniformly thick extrusion profile for the arm and the hook structure is preferred; it provides a product of substantially equal strength throughout and thus is less susceptible to distortion.
Optionally, the hook (i.
e.
, the leg 14 and hook 12) may be thicker but not over about two times the thickness of the mounting arm (at its portion of greatest thickness).
The mounting arm 20 is best formed to be straight and of substantially uniform thickness throughout its length.
It may be thinner at its cantilevered end 24 than at its base end 22 and might be somewhat wedged in profile, but best results are achieved in extrusion by using a substantially uniformly thick mounting arm profile.
The profile thickness should lie between about 0
