Z-shaped closure member for raised seam roofs

摘要

A Z-closure member for raised seam roofs is formed through bending techniques into a shape having a ventilated central vertical member, an upper mounting flange having a return upper retainer member terminating rearwardly of the central member, and a lower flange extending from said central member and terminating rearwardly thereof to define a cavity for the insertion of a filter against the central member. A plurality of filter retention devices are disclosed for restraining movement of the filter, including adhesive placed on said central opening, an upper tab integrally formed with said upper retainer member and extending downwardly therefrom, a flexible locking tab formed as a return from said lower flange and terminating at said cavity, and a raised retention dimple formed in the lower flange adjacent the cavity. An optional rearwardly and upwardly extending deflector member extends from said lower flange to deflect rain passing through the filter.

主权项

1. A Z-shaped closure member for mounting a vent cap on a raised seam roof structure, comprising:
a central member having a front face and a rear face, said central member having ventilation openings formed therein for the passage of air through said central member; an upper flange integral with said central member and extending forwardly from an upper end of said front face approximately orthogonally thereto; an upper retainer member integrally formed with said upper flange and extending from a front terminus of said upper flange in an overlying manner relative thereto to a position spaced a predetermined distance rearwardly of the rear face of said central member; a lower flange integral with said central member and extending rearwardly in an opposing direction relative to said upper flange from a lower end of said front face approximately orthogonally thereto, said upper retainer member, said central member and said lower flange defining a cavity for the insertion of a filter; and filter retention devices incorporated into said upper and lower flanges to restrain movement of said filter away from said central member when said filter is installed in said cavity.
