Abstract

SCREEN DOOR FOR A RADIATOR PACKAGE. A screen door for a vehicle radiator package that includes proximal and distal frame pins, screen surface, torsion bar, stationary support, torsion support, and fastener. The proximal frame pin is articulated to the radiator package, and the distal frame pin can be articulated to a secondary door. The proximal end of the torsion bar is firmly attached to the proximal frame pin, and the distal end is movable relative to the distal frame pin. The stationary support is firmly attached to the distal frame pin. The torsion support is firmly attached to the distal end of the torsion bar and is movable relative to the stationary support. The fastener holds the torsion support in the desired position relative to the stationary support. Movement of the torsion support relative to the stationary support applies adjustable torsion to the torsion bar, and the fastener maintains the adjustable torsion. An adjustment member can be attached to the fastener between the torsion support and the stationary support.

Description

Description Field [001] The present description relates to cooling systems and, more particularly, to torsion rods for counteracting distortion of a screen door in a cooling system. Fundamentals [002] Many motor vehicles include an engine radiator assembly to cool the vehicle's engine. The engine radiator assembly may include a door assembly with a screen door to filter the cooling air and a secondary door. One end of the screen door may be hinged to allow it to be opened for cleaning, and the opposite end of the screen door may be hinged onto the secondary door, wherein the secondary door folds together with the screen door. The hinged and generally perpendicular nature of the secondary door relative to the screen door places the center of gravity of the door assembly in a balanced position where a torque is applied to the screen door, which may deform the screen door and allow the assembly to hang unevenly. In this case, closing the door assembly would require the assembly to be lifted to manually level the assembly and allow the secondary door to be placed in its initial position where it is supported when closed. [003] It would be desirable to neutralize the torque applied to the screen door when the door assembly is opened so as not to deform the screen door and not require the assembly to be manually lifted to level the assembly when closing the assembly. Summary [004] A screen door is described for a vehicle radiator assembly. The screen door includes a proximal frame pin, a distal frame pin, a screen surface, a torsion rod, a stationary support, a torsion support, and a fastener. The proximal frame pin is at a proximal end of the screen door and is articulated to the radiator assembly. The distal frame pin is at a distal end of the screen door. The screen surface extends between the proximal and distal frame pins. The torsion rod has a proximal end firmly attached to the proximal frame pin and a distal end that is movable relative to the distal frame pin. The stationary support is firmly attached to the distal frame pin. The torsion support is firmly attached to the distal end of the torsion rod, and the torsion support is movable relative to the stationary support. The fastener holds the torsion support in a desired position relative to the stationary support. The movement of the torsion support relative to the stationary support applies an adjustable torque to the torsion rod, and the fastener maintains the adjustable torque on the torsion rod. The torsion support may include a fastener connection where the fastener is attached to the torsion support, and the fastener may maintain an adjustable distance between the stationary support and the fastener connection of the torsion support to maintain the adjustable torque on the torsion rod. The stationary support may include a rod opening, and the distal end of the torsion rod may pass through the rod opening and rotate freely within the rod opening. The stationary support may include a groove, and the fastener may extend into the groove and be movable within the groove. The screen door may also include an adjustment member that is affixed to the fastener between the torsion support and the stationary support. The fastener may be a threaded screw, and the adjustment mechanism may be a nut threaded onto the threaded screw. The fastener connection of the torsion bracket can be a threaded hole in the torsion bracket, and the threaded screw can be threaded through the threaded hole in the torsion bracket and extend into the inside of the stationary bracket groove; and the nut can be threaded onto the threaded screw between the threaded hole in the torsion bracket and the stationary bracket groove. [005] The screen door may also include an upper frame member extending between the proximal frame pin and the distal frame pin on the top of the screen surface. The upper frame member may include a top cover and one or more guides fixed to the top cover, and the torsion rod may pass through one or more guides and rotate freely in one or more guides. The screen surface may have a pleated shape, and the upper frame member may also include front and rear covers fixed to the top cover, wherein the front cover has a sawtooth shape that fits into the pleated shape of the screen surface on one front side of the screen surface, and the rear cover has a complementary sawtooth shape that fits into the pleated shape of the screen surface on the rear side of the screen surface. [006] The vehicle radiator package may include a secondary door; and the screen door may also include an accessory mechanism connected to the distal frame pin, wherein the accessory mechanism is configured to attach the secondary door to the distal frame pin. The accessory mechanism may include a hinge and the secondary door may be hingedly attached to the distal frame pin.
