Abstract:
A rechargeable electric fan with a fan portion, a base portion, and a telescoping mast hingedly attached to and connecting the fan portion and the base portion. The fan portion has removable front grille, engageable in a first position in which the grille is retained in the front opening of the housing of the fan portion. The grille is rotatable from the first position to a second position in which the grille is released from the front opening. Slots are disposed on a periphery of the grille, and are configured to engage with corresponding tabs disposed on a periphery of the front opening, to retain the grille in the first position, and to release the grille when it is rotated into the second position. To prevent inadvertent release of the grille, a latch mechanism is configured and disposed to lock the grille in the first position, the latch mechanism comprising a button and a latch configured and disposed to release the lock when the button is depressed. The base portion comprises an oscillating mechanism including of a motor-driven pinion which engages an annular gear in the floor of the base portion. The floor is rotatably retained to the remainder of the base portion, so that when the pinion is turned by the motor, the entire fan turns about the stationary floor.
