Abstract
The present invention is related in general to air circulators, and in particular, to an air circulator with a vein control system to direct and adjust airflow patterns. According to an exemplary embodiment, the present invention provides adjustable, vertical veins that are attached to the outlet of a tower fan. According to a preferred embodiment, the veins are pivotally mounted in such a way that by turning a knob, the veins can either he directed into a focused air-flow pattern or adjusted to a divergent air-flow pattern, or at any setting in between.
Claims1
An air circulation system, wherein the air circulation system comprises:
- a blower;
- wherein the blower is vertically aligned;
- wherein the blower directs a laminar flow of air in a direction which is perpendicular to the vertical alignment of the blower;
- a mounting platform, wherein the mounting platform is secured above the blower;
- wherein the major axis of the mounting platform is aligned substantially parallel to the laminar flow of the air from the blower;
- a front post and a rear post secured to the mounting platform;
- wherein the front post and the and rear post are arranged along a line which is parallel to the laminar flow of the air from the blower;
- a cam system;
- wherein the cam system comprises a cam knob, a cam stem and a cam lobe;
- wherein the cam lobe is rotatably secured to the mounting platform;
- further wherein the cam knob is secured to the cam lobe by a vertically aligned cam stem;
- an air outlet portion, wherein the air outlet portion is comprised of a plurality of veins;
- wherein the veins are vertically aligned;
- wherein each of the veins is comprised of a plurality of upstream ribs and at least one downstream rib;
- wherein the upstream ribs and the at least one downstream rib are joined at a center axis;
- wherein the upstream ribs are aligned in a first direction;
- wherein the at least one downstream rib is aligned in a second direction which is offset from the first direction;
- wherein each of the plurality of veins further comprises at least one pivot pin;
- wherein the at least one pivot pin of each vein is attached to at least one upstream rib;
- a slide mechanism, wherein the slide mechanism comprises:
- an upper slot, wherein the upper slot encloses and is mechanically engaged with the cam lobe;
- a front slide slot, wherein the front slide slot encloses and slidably engages with the front post;
- a rear slide slot, wherein the rear slide slot encloses and slidably engages with the rear post;
- and
- a plurality of angled slots;
- wherein each of the angled slots is formed within the body of the slide mechanism;
- wherein each of the angled slots is aligned in a different direction so that the lines along the major axes of any two of the angled slots intersect at exactly one point;
- wherein, each of the pivot pins of the plurality of veins is slidably engaged within an angled slot;
- wherein each of the pivot pins is configured to slide within an angled slot when the slide mechanism is horizontally translated along the upper platform in response to the horizontal translation of the cam lobe within the upper slot of the slide mechanism.
