Z-Closure Member with Filter Retention Features

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 terminating in an upper tab member, and a lower flange member extending in an opposing direction from the upper mounting flange member and terminating in a flexible locking tab. The lower flange is secured to a raised seam roofing panel with fasteners, while the vent cap formed with a return lip is engaged with the upper flange by capturing the upper flange within the return lip. A fastener can be inserted through the vent cap return lip and the upper flange to secure the vent cap to the Z-closure member. A mesh filter is trapped against the vertical member by the upper tab member and the lower flexible locking tab. A seal can be added to the lower flange to seal against the roofing panel.

主权项

1. A Z-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; 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; an upper tab member integral with said upper retainer member and extending downwardly therefrom and terminating below said upper retainer member and rearwardly of the rear face of said central member; a lower flange integral with said central member and extending rearwardly from a lower end of said front face approximately orthogonally thereto; and a flexible locking tab integrally formed with said lower flange and extending forwardly from a rear terminus of said lower flange and terminating rearwardly of the rear face of said central member and above said lower flange.
