Abstract

See full text

An electric motor driven fan device has a base member with walls forming an enclosure, an electrically powered motor located within the enclosure and having an output shaft coupled via a bearing mounted in an upper wall of the base member to one end of a flexible drive shaft rotatably enclosed in a bendable sheath secured to the base member. The other end of the flexible drive shaft is coupled via a second bearing to a driven shaft secured to a multi-bladed fan. The other end of the bendable sheath is secured to the outer race of the second bearing. The predominant mass of the device is at the bottom, which reduces the footprint of the lower portion. The bendable sheath enables the attitude of the fan to be manually adjusted.
