Abstract

A standing seam formed by overlapping male and female sidelaps, the male sidelap forming a male locking tab and the a female sidelap forming a female first cavity, a female second cavity and a female third cavity, the sidelaps hook and rolled and interconnected so that a female first portion and a male first portion are substantially parallel, a female second portion and male second portion are substantially parallel, and a female third portion and male locking tab are substantially parallel, the junction of the male first and second portions is disposed in the female first cavity, the junction of the male second and third portions is disposed in the female second cavity, and the male locking tab is disposed in the female third cavity, the female third portion and male locking tab extending toward the female and male first portions.

Claims

1. A standing seam roof assembly comprising:

a first panel with a male sidelap having a male first leg and a male second leg extending from the first male leg, and a male locking tab extending from the male second leg; and

a second panel with a female sidelap having a female first leg and a female second leg extending substantially normal from the female first leg and forming therewith a female first cavity, the female sidelap having a female third leg extending from the female second leg forming therewith a female second cavity and a female hook leg extending from the female third leg forming therewith a female third cavity, the female sidelap and the male sidelap overlapped so that the female first leg and male first leg are substantially parallel, the female second leg and the male second leg are substantially parallel, and the female third leg and the male locking tab are substantially parallel, the male first leg and male second leg disposed in the female first cavity, the male second leg disposed in the female second cavity, and the male locking tab disposed in the female third cavity.

2. The roof assembly of claim 1 further comprising clip means for connecting male sidelap to the support structure.

3. The roof assembly of claim 2 wherein the clip means comprises:

a clip first leg disposed between the female first leg and the male first leg;

a clip second leg disposed between the female second leg and the male second leg; and

a clip locking tab disposed between the female third leg and the male locking tab, the end of the clip locking tab disposed in the female third cavity.

4. A standing seam roof assembly comprising:

a first panel with a male sidelap having male first and second legs and a male locking tab;

a second panel with a female sidelap having a female first and second legs substantially normal to each other and forming a female first cavity, having a female third leg forming a female second cavity with the female second leg, and having a female hook leg forming a female third cavity with the female third leg; and

wherein the female sidelap and the male sidelap are hook and rolled to interconnect so as to be overlapped so that the female first leg and the male first leg are substantially parallel, the female second leg and the male second leg are substantially parallel, the female third leg and the male locking tab are substantially parallel;

whereas the junction of the male first and second legs is disposed in the female first cavity, the junction of the male second and third legs is disposed in the female second cavity, and the end of the male locking tab is disposed in the female third cavity; and

whereas the female third leg and male locking tab are formed to extend together toward the female and male first legs.

5. The roof assembly of claim 4 further comprising clip means for connecting the male sidelap to the support structure.

6. The roof assembly of claim 5 wherein the clip means comprises

a clip first leg disposed between the female first leg and the male first leg;

a clip second leg disposed between the female second leg and the male second leg; and

a clip locking tab disposed between the female third leg and the male locking tab, the end of the clip locking tab disposed in the female third cavity.

7. A standing seam comprising:

a male sidelap having male first and second legs and a male locking tab;

a female sidelap having female first and second legs substantially normal to each other and forming a female first cavity, having a female third leg forming a female second cavity with the female second leg, and having a female hook leg forming a female third cavity with the female third leg; and

wherein the female sidelap and the male sidelap are hook and rolled to interconnect so as to be overlapped so that the female first leg and the male first leg are substantially parallel, the female second leg and the male second leg are substantially parallel, the female third leg and the male locking tab are substantially parallel;

whereas the junction of the male first and second legs is disposed in the female first cavity, the junction of the male second and third legs is disposed in the female second cavity, and the end of the male locking tab is disposed in the female third cavity; and

whereas the female third leg and male locking tab are formed to extend together toward the female and male first legs.

8. The standing seam of claim 7 further comprising clip means for connecting the male sidelap to the support structure.

9. The standing seam of claim 8 wherein the clip means comprises:

a clip first leg disposed between the female first leg and the male first leg;

a clip second leg disposed between the female second leg and the male second leg; and

a clip locking tab disposed in the female third cavity.

10. A method of installing a roof assembly in which adjacent panel sidelaps in overlapping edge relationship to form a standing seam, comprising the steps of:

positioning a female sidelap that has a female first leg, a female second leg extending substantially normal to the female first leg, a female third leg extending from the second leg and forming a female retention cavity at the end thereof;

positioning a male sidelap that has a male first leg, a male second leg extending substantially normal to the male first leg, and a male locking tab extending from the second leg;

hooking the male locking tab in the retention cavity as the female sidelap overlaps the male sidelap so that the male sidelap has an upwardly directed force as the male sidelap is rotated, the female and male sidelaps elastically overlapped with the female and male first legs being substantially parallel, the female and male second legs being substantially parallel, and the female third leg and the male locking tab being substantially parallel.

11. The method of claim 10 further comprising the step of:

seam forming the female and male sidelaps so that the female third leg and male locking tab extend together toward the female and male first legs.

12. The method of claim 11 further comprising the step of:

seam forming the female and male sidelaps so that the female third leg and the male locking tab extend in an upwardly inclined direction toward the female and male first legs.

13. The method of claim 12 further comprising the step of:

positioning a clip member so that a first clip leg is disposed between the female first leg and the male first leg, a clip second leg is disposed between the female second leg and the male second leg, and a clip locking tab is disposed in the female third cavity.
