Claim 1
Independent Claim
339 words
A hanger assembly for suspending a curtain with its upper edge spaced a predetermined distance below a support, comprising: a series of trolleys, each trolley comprising a trolley body having roller means for traveling engagement in opposite directions in a support, the trolley body having connecting means facing in the opposite directions of travel of the roller means located at a position close to the roller means and including a downwardly depending hanger member extending at least 18 inches from the roller means, the hanger member having suspending means at its lower end for suspending a curtain; collapsible link means for connecting successive trolley bodies in the assembly and for transmitting pulling force from one trolley body to the next, each collapsible link means comprising first and second elongate arms having adjacent inner ends and outer free ends for releasable connection to successive trolley bodies in the assembly, a hinge connection between the adjacent inner ends of the arms, one connecting means of each trolley body being pivotally connected to the free end of the first arm of one link means and the opposite side connecting means of the trolley body being pivotally connected to the free end of the second arm of the next successive link means in the assembly; each arm having a loop at its free end and said connecting means of said trolley body comprising chambers at opposite side edges of said trolley body, the loops of each link comprising means for pivotal engagement in the chambers at the adjacent side edges of successive trolley bodies; each trolley body having a reduced width passageway at each side edge connecting that side edge of the trolley body to the chamber at that side; and each loop comprising side arms and a thickened end portion connecting the arms, the side arms being thin enough to pass along the passageway and the end portion being thick enough to be locked in the chamber when the loop is rotated so that the end portion extends transversely through the chamber.

Claim 3
Dependent Claim
18 words
The assembly of claim 1, wherein each trolley and depending hanger member are formed integrally of plastic material.
Claim 4
Dependent Claim
29 words
The hanger assembly of claim 1, wherein the suspending means comprise hooks secured to the lower ends of successive hanger members for attachment to spaced points on a curtain.
Claim 5
Dependent Claim
17 words
The hanger assembly of claim 1, wherein each hanger member comprises a rod of relatively stiff material.
Claim 6
Dependent Claim
38 words
The hanger assembly of claim 1, wherein each trolley body is wider than the roller means in the direction of travel of the roller means to prevent contact between the roller means of successive trolleys in the assembly.
Claim 7
Dependent Claim
31 words
