Abstract
A ceiling fan (10) is disclosed having a motor housing (11) with an electric motor to which is mounted an annular array of blade irons (14) each having a blade (15) mounted thereto. Each blade has two, catch mounting holes (17) and a fastener mounting hole (18) extending therethrough. Each blade iron (14) has a blade mounting portion (23) and a removable blade fastener (24). The blade mounting portion (23) has a top surface (26), two stationary mounting catches (27), and a fastener receiver (28) that is configured to receive fastener (24). Each catch has a generally vertical portion (31) and a top, horizontal portion (32) The horizontal portion (32) is spaced a select distance from the top surface (26) through the height of the vertical portion (31) so as to catch snugly the blade (15) therebetween. The fastener (24) extends through the fastener mounting hole 18 and into the fastener receiver (28). The blade may be mounted to the blade iron by passing the catches through the catch mounting holes, sliding the blade outboard and then passing the fastener through the fastener mounting holes of the blade and into the fastener receiver in the blade iron.
