Abstract
A roof curb installation tool has a pair of sliding hinged hooks for lifting the edge of a metal roof panel, and a pair of clamping tangs which can be secured to a vertical roof seam while a curb is being installed at a hole in the roof.
Description
SUMMARY OF THE INVENTION
The invention is directed towards facilitating the placement of internally flanged curbs on metal roofs.
The present invention is directed towards the provisions to workers of a tool with which they can lift up and hold the edge of a metal panel while installing a curb on a seamed roof.
In accordance with one aspect of the present invention, there is provided a roof curb installation tool for lifting and holding an edge of a metal panel running transverse to a standing seam previously formed between that panel and an adjacent panel, said tool comprising an elongate bar, at least two carriers, each having a body adapted for sliding along said bar, each body having a hinge and a hook connected to the body by said hinge, and a pair of clamping tangs welded to said bar adjacent one another, with a space between them just sufficient to receive the standing seam.
In accordance with another aspect of the present invention, there is provided a method of lifting and holding an edge of a metal roof panel running transverse to a standing seam previously formed between that panel and an adjacent panel, said method comprising steps of providing a tool having an elongate bar, a pair of carriers each having a body adapted for sliding along said bar and a hook hinged to the body, and a pair of clamping tangs welded to said bar adjacent one another, with a space between them just sufficient to receive the standing seam, placing the tool transversely across the seam, and parallel to and above said edge, with said clamping tangs disposed vertically above and astride the seam, engaging said hooks beneath said edge, rotating the bar so as to draw the hooks upward and force the clamping tangs downward against the roof panels, and applying a clamp to the seam above the clamping tangs to secure the bar in its rotated position.
BRIEF DESCRIPTION OF THE DRAWINGS
In the accompanying drawings, Figure 1 is an isometric view of a roof curb installation tool embodying the invention;
Figure 2 is a detail of a hook carrier shown in Figure 1;
Figure 3 is a perspective view of the tool as it is first applied a curb installation j ob; and Figure 4 - 6 show, in a simplified form, a sequence of steps in which the curb installation is effected.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A roof curb installation tool embodying the invention includes a bar 10 of metal tube stock having two or more adjustable sliding carrier assemblies 12 thereon. The bar has a rectangular (preferably square) cross section, and thus has four longitudinal edges. A four-foot length of two-inch square stock is presently contemplated, but the best dimensions may vary with the application. Longer lengths could be built up from two or more bars having a telescoping fit or complementary ends shaped as pins and sockets.
Two roof seam clamping 14 tangs are welded to one face of the bar, midway between its ends, and extend perpendicularly away from the face at one of the edges.
Each adjustable carrier assembly includes a body 16 having a sliding fit on the bar 10, and a hook 18 attached thereto by means of a hinge 20. The carrier is oriented with respect to the bar so that the hinges and the clamping tangs are diagonally opposite one another, when viewed along the length of the bar.
The ends 22 of the hooks are flat, so that they can be inserted into a narrow gap beneath a roof panel, and are bent at about a ninety degree angle approximately 2 3/4" from the hinge points, allowing the hook ends to extend just below the flats of fully seamed MR-24 panels when the tool body is laid across the seams and rotated so that the hinge points are at the lowest point on the tube.
The fact that the bodies can slide on the bar allows the hooks to be placed at various intervals along the length of the bar. A series of holes 26 are drilled through at least one wall of the bar, and the carrier assembly 12 has a latch mechanism which releasably engages any of the holes. The latch mechanism includes a U-shaped bracket 28 whose arms are welded to the body, an a T-shaped pin 30 which extends through a hole 32 in the bracket and an aligned hole 34 in the body. A compression spring 36 is disposed on the pin, between the bottom surface of the bracket, and a shoulder 38 on the pin. The spring urges the pin toward the bar, so it snaps into a hole 26 in the bar when that hole is aligned with holes 32 and 34. One releases the pin from the bar by pulling up on the handle 40.
The seam clamping tangs referred to above are short U-channel-shaped metal pieces attached near the center of the tube and spaced just far enough apart to straddle the machine-formed portion of the MR-24 and VRS panel seams.
The tool is particularly useful for lifting the flat portion of the up-slope roof panels above the plane of the roof, so that a worker to can slide an internally flanged curb diverter plate "D" beneath a roof panel, as suggested in Figure 3: The process, illustrated in Figs.
4 - 7, is described below.
After a hole has been cut in the roof, the curb installation tool is placed across the roof panel seams just over the upslope edge of the hole. The tool is oriented with the hooks 18 facing the down slope direction and the clamping tangs 14 facing perpendicularly up from the roof plane. The bar is placed with the clamping tangs above a roof panel seam, one on either side of the seam.
The hooks 18 are allowed to hang downward from the tool body, with their ends extending underneath the edges of the roof panels. The, carrier assemblies 12 are then moved along the tool body, if necessary, to desired lifting spots on the panel edges.
With the hooks now engaged under the roof panels (Fig. 4), the bar is rolled (Fig. 5) in an upslope direction one-quarter turn. This rotation draws the hooks upward, and the hooks lift the flat portions of the panels as a consequence. The clamping tangs pass downward, as the bar is turned, on either side of the roof seam "S" over which they have been centered, and come to rest (Fig. 6) against the tops of the metal panels. Now a locking pliers "P" (Figs. 3 and 6) is attached tightly to the roof panel seam, holding the clamping tangs down against the panels, thus keeping the tool body from rotating back to its initial position.
The tool is left in the rotated position until the diverter plate has been properly positioned under the roof panels.
After the diverter plate has been inserted under the roof panel edge, the locking pliers may be removed from the panel seam and the curb installation tool is allowed to rotate back to its original position. The hooks are then slid out from between the roof panels and the diverter plate, and the curb installation tool is removed.
Since the invention is subject to modifications and variations, it is intended that the foregoing description and the accompanying drawings shall be interpreted as only illustrative of the invention defined by the following claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A roof curb installation tool embodying the invention includes a bar 10 of metal tube stock having two or more adjustable sliding carrier assemblies 12 thereon. The bar has a rectangular (preferably square) cross section, and thus has four longitudinal edges. A four-foot length of two-inch square stock is presently contemplated, but the best dimensions may vary with the application. Longer lengths could be built up from two or more bars having a telescoping fit or complementary ends shaped as pins and sockets.
Two roof seam clamping 14 tangs are welded to one face of the bar, midway between its ends, and extend perpendicularly away from the face at one of the edges.
Each adjustable carrier assembly includes a body 16 having a sliding fit on the bar 10, and a hook 18 attached thereto by means of a hinge 20. The carrier is oriented with respect to the bar so that the hinges and the clamping tangs are diagonally opposite one another, when viewed along the length of the bar.
The ends 22 of the hooks are flat, so that they can be inserted into a narrow gap beneath a roof panel, and are bent at about a ninety degree angle approximately 2 3/4" from the hinge points, allowing the hook ends to extend just below the flats of fully seamed MR-24 panels when the tool body is laid across the seams and rotated so that the hinge points are at the lowest point on the tube.
The fact that the bodies can slide on the bar allows the hooks to be placed at various intervals along the length of the bar. A series of holes 26 are drilled through at least one wall of the bar, and the carrier assembly 12 has a latch mechanism which releasably engages any of the holes. The latch mechanism includes a U-shaped bracket 28 whose arms are welded to the body, an a T-shaped pin 30 which extends through a hole 32 in the bracket and an aligned hole 34 in the body. A compression spring 36 is disposed on the pin, between the bottom surface of the bracket, and a shoulder 38 on the pin. The spring urges the pin toward the bar, so it snaps into a hole 26 in the bar when that hole is aligned with holes 32 and 34. One releases the pin from the bar by pulling up on the handle 40.
The seam clamping tangs referred to above are short U-channel-shaped metal pieces attached near the center of the tube and spaced just far enough apart to straddle the machine-formed portion of the MR-24 and VRS panel seams.
The tool is particularly useful for lifting the flat portion of the up-slope roof panels above the plane of the roof, so that a worker to can slide an internally flanged curb diverter plate "D" beneath a roof panel, as suggested in Figure 3: The process, illustrated in Figs.
4 - 7, is described below.
After a hole has been cut in the roof, the curb installation tool is placed across the roof panel seams just over the upslope edge of the hole. The tool is oriented with the hooks 18 facing the down slope direction and the clamping tangs 14 facing perpendicularly up from the roof plane. The bar is placed with the clamping tangs above a roof panel seam, one on either side of the seam.
The hooks 18 are allowed to hang downward from the tool body, with their ends extending underneath the edges of the roof panels. The, carrier assemblies 12 are then moved along the tool body, if necessary, to desired lifting spots on the panel edges.
With the hooks now engaged under the roof panels (Fig. 4), the bar is rolled (Fig. 5) in an upslope direction one-quarter turn. This rotation draws the hooks upward, and the hooks lift the flat portions of the panels as a consequence. The clamping tangs pass downward, as the bar is turned, on either side of the roof seam "S" over which they have been centered, and come to rest (Fig. 6) against the tops of the metal panels. Now a locking pliers "P" (Figs. 3 and 6) is attached tightly to the roof panel seam, holding the clamping tangs down against the panels, thus keeping the tool body from rotating back to its initial position.
The tool is left in the rotated position until the diverter plate has been properly positioned under the roof panels.
After the diverter plate has been inserted under the roof panel edge, the locking pliers may be removed from the panel seam and the curb installation tool is allowed to rotate back to its original position. The hooks are then slid out from between the roof panels and the diverter plate, and the curb installation tool is removed.
Since the invention is subject to modifications and variations, it is intended that the foregoing description and the accompanying drawings shall be interpreted as only illustrative of the invention defined by the following claims.
