Abstract:
An air circulator unit with adjustable size comprising, in combination:a housing including a pair of halves each including a top face, a bottom face and a pair of end faces for defining an interior space, an open front face and an open rear face, the housing further including a length adjuster having a pair of ends coupled to the end faces of the halves of the housing with a plurality of bellows formed therebetween for allowing the movement of the halves along a single axis;an elastomeric sealing strip mounted along a central extent of the top face, the bottom face and outer end face of each of the halves of the housing for affording a seal between a window and a sill of a window frame;a plurality of fan units each mounted within the interior space of each of the halves in side-by-side relationship along parallel axes, each fan unit including a first slide switch mounted on a front edge of the top face of the associated halve of the housing above the corresponding fan unit for directing air from the open front face to the open rear face in a first orientation, directing air from the open rear face to the open front face in a second orientation and precluding the flow of air in a third orientation, wherein each fan unit further includes a second slide switch mounted on the front edge of the top face of the associated halve of the housing above the corresponding fan unit for controlling a speed at which the fan unit directs air; andtwo sets of horizontally oriented vanes each pivotally mounted between front edges of the end faces of one of the halves of the housing, each set of vanes including a lever mounted on the front edge of the outer end face of the corresponding halve of the housing for controlling the flow of air upwardly and downwardly.
