Abstract
A pair or more of three-piece brackets (20) are provided for mounting the longitudinal edges of a window blind headrail (11). Each bracket includes a frame (21) with apertures (22) for mounting to a window frame top or ceiling (15). The frame (20) includes spaced depending apertured tabs (24, 25) through which a slidable tongue (30) is positioned. The distal ends (41) of an arrow spring (40) are confined by tangs (31) on tongue (30) and the other spring end (42) abuts and is confined by a notch (39) in tab (25). A top front lip (12) of the headrail (11) is tilted and positioned on the tongue (30) and then pushed inwardly to move the tongue (30) and compress spring (40) which allows the top rear lip (14) of the headrail (11) to rotate and clear a lip portion (25b) of tab (25) to a position within the lip portion (25b). Release of the pushing force releases the spring energy, forcing the tongue (30) back so that the headrail (11) is clamped between tongue (30) and tab (25). Bifurcated ramped legs (32) on one end of the tongue (30) prevent disassembly of the bracket.
