Snow blocking device for attachment to corrugated metal roofs
First Claim
1. A roof snow guard for retained assembly with a peaked type of metallic corrugated roof having transversely spaced generally vertically inclined peak shaped corrugations thereon, the snow guard including an angular bar having an approximate length corresponding to the distance between corrugations on the roof, a pair of peak shaped brackets at opposite ends of the angular bar, welds fixedly connecting the peak shaped brackets to opposite ends of the angular bar, the peak shaped brackets each defining peak shaped channels, said peak shaped channels being sized for nested engagement in gap relationship over the vertically inclined peak shaped corrugations to allow for differences in coefficients of expansion and with the peak shaped channels extending generally at right angles to the angular bar, the angular bar including a downwardly extending bar leg positioned between the peak shaped brackets, the bar leg being positioned on the snow guard and located when installed in vertically spaced overlying relationship to the metallic corrugated roof for inhibiting downward sliding movement of snow on the roof while allowing melted snow or rain to slide downwardly on the roof and to pass beneath the downwardly extended bar leg.

Abstract
A roof snow guard for retained assembly with a peaked type of metallic corrugated roof having transversely spaced generally vertically inclined corrugations thereon. The snow guard including an angular bar having an approximate length corresponding to the distance between peaks on the roof. A pair of channel shaped brackets are provided at opposite ends of the angular bar. Welds fixedly connect the channel shaped brackets to opposite ends of the angular bar. The channel shaped brackets each define channels for engagement over the corrugations with the channels extending generally at right angles to the angular bar. The angular bar includes a downwardly extending bar leg positioned between the channel shaped brackets and which is adapted to be positioned in vertically spaced overlying relationship to the metallic corrugated roof for inhibiting downward sliding movement of snow on the roof while allowing melted snow or rain to slide downwardly on the roof and to pass beneath the downwardly extended bar leg.

- 14. A roof snow guard for retained assembly with a peaked type of metallic corrugated roof having transversely spaced generally vertically inclined peak shaped corrugations thereon, the snow guard including an intermediate angular portion having an approximate length corresponding to a distance between corrugations on the roof, a pair of peak shaped bracket portions integral with opposite ends of the angular intermediate portion, the peak shaped brackets each defining peak shaped channels, said peak shaped channels being sized for engagement in gap relationship over the vertically inclined corrugations to allow for differences in co-efficients of expansion and with the channels extending generally at right angles to the angular intermediate portion, the angular intermediate portion including a downwardly extending guard leg positioned between the peak shaped brackets, the guard leg being positioned on the snow guard and located when installed in vertically spaced overlying relationship to the metallic corrugated roof for inhibiting downward sliding movement of snow on the roof while allowing melted snow or rain to slide downwardly on the roof and to pass beneath the downwardly extended bar guard.
- 19. In combination, a corrugated roof, and a roof snow guard in retained assembly with the metallic corrugated roof, the roof having transversely spaced generally vertically inclined peak shaped corrugations thereon, the snow guard including an intermediate angular portion positioned between an adjacent pair of the corrugations on the roof, a pair of peak shaped bracket portions integral with opposite ends of the angular intermediate portion, the peak shaped brackets each defining peak shaped channels, said peak shaped channels being sized in gap relationship over the vertically inclined peak shaped corrugations to allow for differences in co-efficients of expansion and with the peak shaped channels extending generally at right angles to the angular intermediate portion, the angular intermediate portion including a downwardly extending guard leg positioned between the peak shaped brackets, the guard leg being positioned on the snow guard and located in vertically spaced overlying relationship to the metallic corrugated roof for inhibiting downward sliding movement of snow on the roof while allowing melted snow or rain to slide downwardly on the roof and to pass beneath the downwardly extended bar guard.
