Abstract
Abstract A pitch pocket is formed on a roof about projecting structure members by interfitting four identical corner wall units together and the area enclosed by the pitch pocket is determined by the extent of overlapping of the interfitting wall sections of the units. Wall sections of straight wall units may be similarly interfitted with the wall sections of corner units to increase the normal length of the sides of the pitch pocket to increase the area enclosable by four corner units.

Total Claims: 9
Claim 1
Independent Claim
219 words
A wall unit for constructing a polyangular pitch pocket structure or the like and comprising first and second upright plane wall sections joined at one end and disposed at less than 180* to one another to form two contigious sides of a corner of the pitch pocket structure, the extended end portions of said wall sections terminating in the plane of their respective wall sections whereby said wall sections are adapted to lie alongside and overlap wall sections of like wall units to form sides of the pitch pocket structure having lengths greater than the lengths of the individual wall sections, a base flange extending laterally from the bottom edge of each wall section, and means forming a downwardly facing slot along the top edge of said first wall section, said slot having a width at least the thickness of said second wall section and adapted to receive the top edge portion of the second wall section of another wall unit like said wall unit, the bottom surface of the base flange extending from said first wall section lying in a plane offset upwardly relative to the plane of the upper surface of the base flange extending from said second wall section, said offset of the first mentioned plane being approximately the thickness of the last mentioned base flange.

A wall unit for constructing a polyangular pitch pocket structure or the like and comprising first and second upright plane wall sections joined at one end and disposed at less than 180* to one another to form two contigious sides of a corner of the pitch pocket structure, the extended end portions of said wall sections terminating in the plane of their respective wall sections whereby said wall sections are adapted to lie alongside and overlap wall sections of like wall units to form sides of the pitch pocket structure having lengths greater than the lengths of the individual wall sections, a base flange extending laterally from the bottom edge of each wall section, and means forming a downwardly facing slot along the top edge of said first wall section, said slot having a width at least the thickness of said second wall section and adapted to receive the top edge portion of the second wall section of another wall unit like said wall unit, the bottom surface of the base flange extending from said first wall section lying in a plane offset upwardly relative to the plane of the upper surface of the base flange extending from said second wall section, said offset of the first mentioned plane being approximately the thickness of the last mentioned base flange.
Claim 3
Dependent Claim
29 words
A wall unit as defined in claim 1 further characterized by said first and second upright wall sections joined at one end being disposed at 90* to one another.
Claim 4
Dependent Claim
38 words
A wall unit as defined in claim 1 further characterized by said downwardly facing slot being disposed at the side of said first wall section opposite the side from which said base flange of said first wall projects.
Claim 5
Dependent Claim
35 words
A wall unit as defined in claim 1 further characterized by said flanges being disposed on said wall sections so as to project from the outer sides of the corner formed by said wall sections.
Claim 6
Dependent Claim
38 words
A wall unit as defined in claim 2 further characterized by said downwardly facing slot being disposed at the side of said first wall section opposite the side from which said base flange of said first wall projects.
Claim 7
Dependent Claim
35 words
A wall unit as defined in claim 2 further characterized by said flanges being disposed on said wall sections so as to project from the outer sides of the corner formed by said wall sections.
Claim 8
Dependent Claim
195 words
A polyangular pitch pocket structure comprised of a plurality of descrete like corner units, each unit comprising first and second upright planar side wall sections joined at one end and extending from one another at less than 180* to form a corner of the pitch pocket, the first wall section of one corner unit lying alongside at least a portion of the second wall section of a second corner unit and cooperating therewith to form a side of the pitch pocket between two adjacent corners thereof, a base flange extending laterally from the bottom edge of each of said wall sections, and means forming a downwardly facing slot along the top edge of said first wall section of each unit, said slot of said one corner unit receiving the top edge portion of said second wall section of said second corner unit, the bottom surface of the base flange extending from said first wall section of said first corner unit lying in a plane offset upwardly from the plane of the top surface of the base flange extending from said second wall of the second corner unit and receiving the last mentioned base flange therebeneath.
