This axial mounting of the bottoms (5) of fan blades provides two levels of flexibility, and features rather low stiffness after using up a predetermined clearance (35) between two stop parts (32, 34), which then imposes a significant increase in stiffness; however significant energy was able to be absorbed through the elastic deformation of certain parts (7, 30) located between the blade and the disc (2), which enables the blade to withstand rather significant momentary forces, for example if a neighboring blade breaks and strikes it.

A blade bracket to releasably connect a blade of a ceiling fan to the rotor, the blade bracket comprising a mount adapted for attachment to the rotor and a blade support securable to the blade and releasably attachable to the mount, the mount comprising means to permit securable attachment to the rotor at one end, and at another end, a sleeve having an entrance and a base, the blade support comprising, at one end, means for securing a fan blade thereto and at another end thereof a neck which is releasably seatable into the mount sleeve through its entrance, and a lock mechanically associated with the mount and adjustable when the neck is seated in the sleeve to lock securely said neck in the sleeve, with the fan blade in proper orientation, for operation of the fan.
