Modular shutter system for poultry house ventilation and insulation
View Patent ↗Disclosed is a modular assembly device for providing adequate and efficient ventilation, temperature control, and insulation in poultry houses. The disclosed invention relates to an automated or manually-operated modular shutter system for tunnel ventilation in poultry houses, the system being self-sealed by the poultry house's internal negative static pressure. All the shutters in a modular shutter unit are designed to open and close in unison by means of specially-designed hinges and hinge spacers. In the preferred embodiment, there are four shutters per modular shutter unit, all of the same construction and dimensions. The shutters are designed with beveled horizontal edges and end cap seals, which together provide an efficient and practically airtight fit against each other when closed. The shutters are also of sufficient thickness to accommodate internal insulation if necessary to raise the insulation values needed for the poultry houses in cold winter months.

a plurality of L-shaped hinges having a hinge arm constructed with a protruding wheel at the longer end of said L-shape and having a bracket orthogonally affixed to the shorter end of said L-shape, wherein the diameter of said protruding wheel is of a dimension allowing insertion into the slot of said vertical rail;
a means for attaching the bracket of said hinges proximate each end of each of said shutters;
a tie bar bracket, constructed with two symmetrical flanges affixed to the midpoint of each said shutters, proximate the beveled edge; and
a plurality of hinge spacers, each comprising (a) a lateral dimension providing for a longitudinal fit within the slot of said vertical rail, (b) an upper notch so as to provide rotational guidance to the circumference of the protruding wheel of a first said hinge, (c) a lower indent so as to provide rotational stabilization to the circumference of the protruding wheel of a second said hinge, and (d) a longitudinal dimension so as to provide an exact amount of vertical separation between the horizontal edges of adjacent shutters; and further, four of said hinge spacers are installed within the rail slot of each the left and the right vertical rail;
said shutters, with hinges attached, are assembled in a parallel, edge-abutting horizontal arrangement wherein the protruding wheels of said hinges, are placed into the slot of each of said vertical rails, in an alternating sequence with said hinge spacers, so as to provide for spacing between successive shutters and to further assist in the simultaneous, coordinated movement of all shutters to and from a vertical closed position to a horizontal open position, or any intervening position.
