Abstract
Abstract Apparatus for use in fabricating paint racks or like structures featuring a unique prestressed hanger device having an inherent capability to firmly grip a support on slip fit thereto. The hanger device of the invention is so constructed to obviate the need for special fastening or bonding means on application of the device to its base support. On suspension of articles therefrom it is inherently endowed with a supplemental and strengthened gripping action.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
Suspension apparatus comprising a rack or like support structure including in mounted relation thereto at least one substantially horizontally extending rodlike support element, at least one spring wire hanger element mounted on said rodlike elemenT, said hanger element including an integrally formed coiled portion having a pressured slip fit upon said rodlike support element obviating slipping and deforming of said hanger element in the presence of a suspended weighted article without need for bonding between said rodlike support element and said hanger element, said hanger element further including end portions defining a pair of arms projecting substantially horizontally and in opposite directions from said rodlike support element in positions relative to said coiled portion that each of said arms under gravity loading by a weighted article suspended substantially perpendicular to the support element acts as a lever to tighten the coiled portion of said hanger element into a more secure gripping engagement with said support element, and each of said arms including retention means for a suspended article.
Claim 2
Dependent Claim
168 words
Suspension apparatus comprising a rack or like support structure including in mounted relation thereto at least one substantially horizontally extending rodlike support element, at least one spring wire hanger element mounted on said rodlike elemenT, said hanger element including an integrally formed coiled portion having a pressured slip fit upon said rodlike support element obviating slipping and deforming of said hanger element in the presence of a suspended weighted article without need for bonding between said rodlike support element and said hanger element, said hanger element further including end portions defining a pair of arms projecting substantially horizontally and in opposite directions from said rodlike support element in positions relative to said coiled portion that each of said arms under gravity loading by a weighted article suspended substantially perpendicular to the support element acts as a lever to tighten the coiled portion of said hanger element into a more secure gripping engagement with said support element, and each of said arms including retention means for a suspended article.
Claim 3
Dependent Claim
43 words
Suspension apparatus as in claim 1 characterized in that at least one of said projected end portions of said hanger element has a form and position providing it will project tangentially of and substantially horizontally from the uppermost limit of said coiled portion.
Claim 4
Dependent Claim
36 words
Suspension apparatus as in claim 1 characterized in that said hanger element has ends which project oppositely of one another and commonly disposed in a horizontal plane transverse to an uppermost portion of said coiled portion.
Claim 5
Dependent Claim
41 words
Suspension apparatus as in claim 1 characterized by said end portions projecting oppositely, approximately 180* apart and each forming a lever on either of which a suspended article will induce a self-locking action of the hanger element to said support element.
Claim 6
Dependent Claim
52 words
Suspension apparatus according to claim 1 characterized by end portions of said hanger element projecting in a sense generally radial to said coiled portion and said end portions forming remote levers a directly dependent load on either of which will induce a self-locking action of the hanger element to said support element.
Claim 7
Dependent Claim
50 words
Suspension apparatus as in claim 1 characterized in that said coiled portion forms a loop of at least 360* in extent and said end portions projecting in different directions to form hooklike suspension devices the loading of which will induce a self-lock of said hanger element to said support element.
Claim 8
Dependent Claim
41 words
Suspension apparatus as in claim 1 characterized in that at least one of said projected end portions extends laterally and immediately of said coiled portion to provide a generally horizontal segment and upwardly facing means for retention of a suspended weight.
Claim 9
Dependent Claim
48 words
Suspension apparatus as in claim 1 characterized by said hanger element including extensions of said coiled portion terminating in said end portions which have a hook form, the suspension of the weight on either of which will produce a self-locking action of the hanger element to said support.
