Abstract
A hinged snap together fan guard has front and rear fan guard members hingedly attached in a unique arrangement. Each of the front and rear fan guard members are generally formed in the shape of a concave dish having a plurality of ribs extending outwardly from a central region to a periphery of the member. Selected ribs on the front guard member terminate, at an outer end, in a hook for engaging with a peripheral rim of the rear fan guard member. At least one selected rib on each fan guard member terminates at an outer end in a loop. The two loops mate with each other, thereby forming a hinge. The front guard member can be moved from a closed position in engagement with the rear fan guard member to an open position, by pivoting the front fan guard member about the hinge. The hinge is preferably located in a lower quadrant of the fan guard, such that when opened, the front fan guard member is pivoted outwardly and downwardly relative to the rear fan guard member. In its open position, the front fan guard member cannot be inadvertently knocked into a closed position.
