发明名称 BUILDING ROOF EAVE MOUNTING GUARD STRUCTURES
摘要 A guard structure for installation at the edge of a building roof eave to assist in shingling and reshingling employs a plurality of spaced roof cleats that are nailed to the roof, each having a hinge at its lower end with a hinge axis parallel to the eave. Each hinge connects the cleat to a respective vertical support member at a junction portion immediately adjacent to the eave. The portion of the support member below the eave or roof line engages with the building structure, e.g. the rafter tail or fascia board, usually through a pressure plate, and may carry a screw-threaded adjustment member for adjustment of the vertical attitude of the support member. The other portion of the support member has a lower outward upward inclined part carrying a toe board retainer member for an inclined toe board, and an upper vertical part carrying at least two vertically spaced back rail support members, as is usually required by building safety regulations. The toe board and the back rail support members form a safety structure for the roofer. Metal safety straps may be provided extending longitudinally beneath the toe boards to prevent catastrophic breakage if they should sag excessively. The upper vertical part may also be provided with a retainer for a vertical horizontally extending catch board; when such acatch board is provided it cooperates with the toe board to form a catch space to prevent debris falling from the structure to the ground and also provides an improved safety structure.
