Snow guard for a metal roof

Abstract

The present invention is directed to a device capable of being attached to a metal roof comprises a substantially perpendicular seam. The device comprises a block. A groove is located in the base of the block, and the block is locatable on the roof by placement of the groove on the seam. There are two embodiments for securing the block to the seam. In the first embodiment, a threaded hole is located in the block between the first side wall and the groove, and a cavity is located in the groove diametrical to the threaded hole. A set screw is locatable in the threaded hole. The set screw has an opening at its terminal end for receiving an element having a curved surface, the element protruding therefrom and pivotable therewithin. Driving the set screw into the hole causes the curved surface of the element to engage the seam, driving the seam towards the cavity of the groove diametric thereto, thereby forming a pocket in the seam, and securing the block to the seam. In the second embodiment, a chamber is located in the base of the block. A cam is pivotally mounted within the chamber and translocatable within the groove. A cavity is located in the groove opposite the cam. Sliding the block along the seam causes the cam to engage the seam, driving the seam towards the cavity, thereby forming a pocket in the seam. Both embodiments secure the block to the roof without piercing or tearing the seam.
