A hand rail assembly for the roof of a grain bin includes plural units each having a plate having openings spaced from each other and adjacent each longitudinal edge of the plate. Some of the openings align with openings in the roof whereby the plate may be attached to the roof. A pair of ring segments extend substantially perpendicular to the plate and rest upon the plate. Openings in the ring segments align with openings in the plate whereby the ring segments may be attached to an upper face of the plate. A gusset extends upwardly from the ring segments, and the gusset and ring segments are attached together. A hand rail comprising a vertical post is attached at one end to the gusset, and a horizontal rail is attached to the post.

1. A hand rail assembly for an inclined roof of a generally cylindrical storage structure, the assembly comprising: an elongate plate extending substantially parallel to the incline of the roof and having an upper face and a lower face facing the roof, said plate having a first pair of openings longitudinally spaced from each other and adjacent one longitudinal edge of said plate, and a second pair of openings longitudinally spaced from each other and adjacent the other longitudinal edge of said plate, the spacing of said first pair of openings being substantially the same as the spacing of openings in the roof whereby the plate may be attached to the roof with the lower face facing the roof by fastening means extending through said first openings and the openings in the roof;a pair of ring segments spaced from each other in the direction of the incline of the roof and extending substantially perpendicular to said elongate plate and constructed and arranged to rest upon said upper face of said plate, a plurality of openings in each of said ring segments at least one of which is aligned with said second pair of openings in said plate whereby said ring segments may be attached to said upper face of said elongate plate by fastening means extending through at least one of said openings in each of said ring segments and said second openings in said plate;a gusset extending substantially parallel to the incline of the roof and upwardly from the side of said ring segments opposite said plate, said gusset and said ring segments having fastening means for attaching them together; anda hand rail comprising a substantially vertical post attached at one end to said gusset, and at least one horizontal rail attached to said post toward its other end. 2. The hand rail assembly of claim 1, wherein said ring segments have a plurality of said openings spaced from each other along the length of said ring segments. 3. The hand rail assembly of claim 2, wherein said openings in said ring segments are slots. 4. The hand rail assembly of claim 3, wherein said gusset is substantially triangular in outline. 5. The hand rail assembly of claim 1, wherein said gusset is substantially triangular in outline. 6. The hand rail assembly of claim 1, including a plurality of said elongate plates, a plurality of said ring segments arranged in end to end relationship to each other and attached to each other, a plurality of said gussets, and a plurality of said hand rails also arranged in end to end relationship to each other and attached to each other and to said gussets. 7. The hand rail assembly of claim 1, wherein the end of said gusset nearest the bottom of said roof is fastened to the ring segment nearest the bottom of the roof, and the end of said gusset nearest the top of said roof is fastened to the ring segment nearest the top of said roof and to said vertical post. 8. The hand rail assembly of claim 7, wherein the end of said gusset nearest the top of said roof is fastened to said vertical post, and the bottom of said vertical post is attached to the ring segment nearest the top of said roof. 9. The hand rail assembly of claim 1, wherein said ring segments flex to permit said ring segments to conform to the curvature of the roof. 10. The hand rail assembly of claim 9, wherein at least one of said ring segments is substantially Z-shaped in cross section comprising an upper and lower flange extending in opposite directions from a web connecting the flanges, said lower flange including said openings in said ring segments, and said flanges including spaced slots which permit said ring segments to flex. 11. The hand rail assembly of claim 1, wherein the generally cylindrical storage structure is a grain bin. 12. The hand rail assembly of claim 6, wherein the generally cylindrical storage structure is a grain bin. 13. A hand rail assembly for an inclined roof of a generally cylindrical storage structure, the assembly comprising: plate extending having an upper face and a lower face and openings spaced from each other and adjacent each longitudinal edge of said plate, the spacing of said openings being substantially the same as the spacing of openings in the roof whereby the plate may be attached to the roof;a pair of ring segments extending substantially perpendicular to said elongate plate which rest upon said plate, openings in each of said ring segments at least one of which is aligned with openings in said plate whereby said ring segments may be attached to said upper face of said plate;a gusset extending upwardly from said ring segments opposite said plate, said gusset and said ring segments are attached together; anda hand rail comprising a substantially vertical post attached at one end to said gusset, and at least one horizontal rail attached to said post toward its other end. 14. The hand rail assembly of claim 13, wherein said ring segments have a plurality of said openings spaced from each other along the length of said ring segments. 15. The hand rail assembly of claim 14, wherein said openings in said ring segments are slots. 16. The hand rail assembly of claim 15, wherein said gusset is substantially triangular in outline. 17. The hand rail assembly of claim 13, wherein said gusset is substantially triangular in outline. 18. The hand rail assembly of claim 13, including a plurality of said elongate plates, a plurality of said ring segments arranged in end to end relationship to each other and attached to each other, a plurality of said gussets, and a plurality of said hand rails also arranged in end to end relationship to each other and attached to each other and to said gussets. 19. The hand rail assembly of claim 13, wherein the end of said gusset nearest the bottom of said roof is fastened to the ring segment nearest the bottom of the roof, and the end of said gusset nearest the top of said roof is fastened to the ring segment nearest the top of said roof and to said vertical post. 20. The hand rail assembly of claim 19, wherein the end of said gusset nearest the top of said roof is fastened to said vertical post, and the bottom of said vertical post is attached to the ring segment nearest the top of said roof. 21.
