  • Patent number: 6821091
    Abstract: A securing device for securing a connecting arm to a ceiling fan blade. The blade includes a hole through which a male member of the arm is inserted. The securing device includes a plate having an aperture through which the engagement end subsequently extends with the neck staying within the aperture. The aperture includes a smaller part having a rim portion such that the plate is slidable in a first direction along the blade surface until the rim portion engages behind the engagement end. The rim portion is enlarged for receiving and engaging with the engagement end in a second direction opposite to the first direction. The plate includes a resilient finger deformable upon engaging the blade surface, resiliently maintaining the engagement of the enlarged rim portion with the engagement end in the second direction. The finger engages the blade surface by friction, thereby holding the plate against sliding relative to the blade in the second direction.

  • Patent number: 6520468
    Abstract: A suspension bracket for mounting a suspension fan having a fan motor including a motor shaft having an upper end with an enlarged support. The bracket includes a body for fixing on a ceiling, and a mount connected below the body and including a substantially horizontal aperture for engaging the support. The aperture has a side opening for accommodating the motor shaft and allowing the support to be moved laterally to the aperture. The bracket includes a fixing plate for closing the side opening of the aperture to retain the support in with the mount in the aperture.

  • Patent number: 6241476
    Abstract: A securing device for securing an arm member with a fan blade is disclosed, in which the arm member includes screws receivable within apertures of the fan blade, in which the screws include a narrower portion which, when the screws are received within the apertures of the fan blade, extend beyond the apertures of the fan blade, in which when the screws of the arm member are received within the apertures of the fan blade, the securing device is movable relative to the arm member in a first direction to engage with the narrower portion of the respective screws, and in which the arm member includes a barrier for preventing the securing device from moving in a direction opposite to the first direction upon engagement of the securing device with the screws, and thereby to secure the arm member with the fan blade by the securing device.
