ABSTRACT:
A pivot assembly that can be used with various appliances. The pivot assembly provides up to three degrees of freedom when positioning the appliance. The pivot may be used, for example, with a fan that is mounted on a base such that direction of the airflow generated can be adjusted about three coordinate axes by manipulating a single rotatable pivot mount. The fan assembly includes a base unit and an arm to which an appliance may be detachably coupled. The opposite end of the arm is provided with a spherical cap which is received by the base unit. Any adjustments to the positioning of the rotatable pivot mount are maintained by the friction within the rotatable pivot mount. Additionally, the pivot mount may include a pivot guide to restrict the degree of rotation about the pivot, thereby increasing stability.
