Abstract

An apparatus to direct cigarette smoke and the like in an ambient environment relative to a filter housing includes a base, with the base mounting a support plate to an upper distal end of an adjustable tube adjustably mounted within the base. A filter housing is mounted to the plate to include a fan organization to direct ambient air through the filter, with a surrounding truncated conical shield oriented about the filter housing to effect directing of smoke and the like to the filter.

Claims

1. A smoke filtering apparatus, comprising,

a pedestal base, the pedestal base including an elongate mounting tube coaxially aligned relative to the pedestal base and telescopingly received within the pedestal base, and

the mounting tube includes a support plate integrally and fixedly mounted to an upper distal end of the mounting tube, and the support plate includes a filter means mounted to a top surface of the support plate for filtration of cigarette smoke therethrough, and

a conical shade fixedly secured relative to the filter housing extending in surrounding relationship relative to the filter housing, wherein the conical shade includes a chimney aligned with the pedestal base, the mounting tube, and the filter housing to direct filtered air therethrough.

2. An apparatus as set forth in claim 1 wherein the mounting tube includes a gear rack mounted to an exterior surface of the mounting tube arranged parallel relative to an axis of the pedestal base, and the gear rack includes a gear wheel in operative engagement with the gear rack, the gear wheel fixedly mounted about a gear wheel axle, the gear wheel axle extending exteriorly of the pedestal base permitting effective rotation of the gear wheel relative to the gear rack, and a locking dog pivotally mounted adjacent the gear wheel for interengagement with the gear wheel for arresting rotation of the gear wheel, wherein the locking dog includes a handle extending exteriorly of the pedestal base with the locking dog positioned interiorly of the pedestal base, and a biasing spring mounted within the pedestal base to bias the locking dog into engagement with the gear wheel.

3. An apparatus as set forth in claim 2 wherein the filter housing includes a housing inlet opening directed into the housing adjacent a lower distal end of the housing, and the housing is arranged in surrounding relationship relative to a plurality of fan blades, the fan blades positioned interiorly of the housing and the fan blades in operative engagement with a fan blade motor, the fan blade motor mounted within an upper portion of the mounting tube, and the fan blades positioned below a charcoal layer within the housing, the charcoal layer contained between a filter housing apertured lower plate and a filter housing apertured upper plate.

4. An apparatus as set forth in claim 3 including a shade support axle rotatably mounted coaxially relative to the filter housing, wherein the shade support axle is coaxially aligned relative to the mounting tube and the pedestal base and orthogonally oriented relative to the support plate, the shade support axle includes a plurality of fan blade shade supports mounted fixedly to an upper distal end of the shade support axle, and the fan blades are positioned within the conical shade chimney coaxially aligned within the conical shade chimney whereupon rotation of the fan blades directs air currents through the fan blade shade supports from the fan blades within the filter housing to effect rotation of the fan blades and the conical shade, and the conical shade including multi-colored panels spaced about the conical shade, wherein the multi-colored panels effect entertainment and amusement of individuals upon rotation of the conical shade.
