Abstract
Abstract A ceiling assembly including a plurality of suspended stringers parallel to each other and an array of horizontally elongated panels extending beneath and transversely of the stringers in spaced parallel relation to each other with major surfaces of the panels oriented vertically, wherein the panels are suspended from the stringers by means of clip elements each having an upper portion received in slots in a stringer and a lower, spring clip portion gripping an upper marginal portion of a panel. Each stringer is a downwardly-opening channel member having paired opposed slots formed therein. The upper portion of each clip element has a pair of opposed tabs respectively received in an opposed pair of such slots, and shaped so as to be readily insertable but to be effectively locked in place after insertion in the stringer slots. The clip elements can be bent intermediate their upper and lower portions for orienting the major surface planes of the panels at a desired angle to the stringers, so that the panel major surface planes are vertical when the stringers are pitched at an angle to the horizontal, as over a stairway.

Claim 4
Dependent Claim
45 words
An assembly as defined in claim 2, wherein one of the tab members of each said clip element has a greater horizontal extent than the other tab member of the same clip element, to facilitate insertion of the tabs into opposed slots of a stringer.
Claim 5
Dependent Claim
42 words
An assembly as defined in claim 2, wherein each tab of each said clip element has an upwardly and outwardly sloping lower edge with a shoulder provided therein to engage the lower edge of a slot in which the tab is inserted.
Claim 6
Dependent Claim
42 words
An assembly as defined in claim 1, wherein the spring clip portion of each said clip element comprises a plurality of depending spring fingers alternately resiliently biased in opposite directions for gripping the upper marginal portion of a panel inserted between them.
Claim 7
Dependent Claim
57 words
An assembly as defined in claim 5, wherein a. the upper marginal portion of each of said panels has at least one longitudinal rib formed therein, and b. the spring fingers of each said clip elements have at least one groove formed therein for register with said one rib of a panel gripped by the spring fingers.
Claim 8
Dependent Claim
62 words
An assembly as defined in claim 6, wherein a. the upper marginal portion of each of said panels has a second longitudinal rib formed therein below and parallel to said one rib, and b. the lower extremity of each spring finger of each said clip element is bent to conform to said second rib of a panel gripped by the spring fingers.
Claim 9
Dependent Claim
50 words
An assembly as defined in claim 1, wherein said stringers extend horizontally at a common level, and wherein the upper and lower portions of each said clip element are formed integrally and lie substantially in a common vertical plane, for suspending panels with major surfaces of the panels oriented vertically.
Claim 10
Dependent Claim
72 words
