Abstract:
1. An exhaust system, comprising: an exhaust fan including a frame within which fan blades and a motor are secured, the frame includes an upper sidewall, a bottom sidewall, a first lateral sidewall and a second lateral sidewall, defining an inlet opening and an outlet opening on opposite sides of the frame; a flexible exhaust boot secured to the frame of the exhaust fan adjacent the outlet opening, the exhaust boot is a flexible piece of material having a substantially tubular configuration with a first end having an opening and a second end having an opening; and a support assembly securing the exhaust fan and exhaust boot in position adjacent an opening; the support assembly includes a vertical bracket having a first end and a second end, and an outwardly extending support block is mounted at the first end of the vertical bracket; a horizontal bracket extending substantially perpendicular to the vertical bracket, the horizontal bracket is shaped and dimensioned to pass through a connection opening in the second end of the vertical bracket, and the horizontal bracket includes first end and a second end, the first end of the horizontal bracket extends outwardly from the same side of the vertical bracket as the support block; and a strap selectively connected to the exhaust fan; wherein the support assembly is secured to the framework of a window by positioning the support block of the vertical bracket upon an upper surface of a ledge defined by the framework of the window, and the first end of the horizontal bracket is oriented such that it extends toward an inner surface of the window, and the support assembly is supported from vertical movement by interaction between the upper surface of the ledge defined by the framework of the window and supported from rotational movement by the interaction of the first end of the horizontal bracket with the inner surface of the window, wherein the strap includes a first end adjustably secured to the vertical bracket and a free second end including a fan hook shaped and dimensioned for selective attachment to the exhaust fan; wherein the movement of the strap relative to the vertical bracket is controlled by a strap stop, and wherein the strap stop includes a rod held within a tapered slot such that the rod may be moved from a wide end of the tapered slot to a narrow end of the tapered slot creating a friction holding the strap in place.
