DESCRIPTION OF THE PREFERRED EMBODIMENTS
The reglet of the present invention is of C-or channel shape and formed to have means by which it is secured to the face of a wall. The various views of the reglet show different types of securing means which may be used to meet different conditions. The reglet 11, illustrated in FIGS. 1 and 2, has a web 12 and outwardly sloping flanges 13 and 14 providing a recess 15 over which the flanges extend. In FIG. 1, the reglet 11 has an elastomeric sealing strip 16 adhered within the recess 17 thereof to extend therebeyond. The sealing strip is compressed against the face of a wall 18 when secured thereagainst by a plurality of securing screws 19. The reglet 11 is mounted above the roof deck 21 in position to support a cant 22 when a reversely extending top flange 23 is engaged over the upwardly extending bottom flange 14. The cant has a bottom flange 24 which is secured to the roof deck by nails 25. A roofing material 26 is placed over the roof deck and extended upwardly with the edges extending into the recess 15 of the reglet to cover the cant. The material is usually layers of felt suitably treated with bitumen and gravel.
A flashing strip 27 may be provided in different forms, the one herein illustrated having an outwardly presenting concaved edge section 28 and an angularly related flange section 29 which is extending outwardly at 31 to provide edge strength. The finishing strip is preferably flexible and is applied to the roofing material by inserting the outer edge 32 of the section 28 into the recess 15 of the reglet in engagement with the inner surface of the flange 13. Apertures 33 are provided through the flange section 29 through which screws 34 extend and through holes punched through the roofing material 26 and the cant 22. A washer 30 having a neoprene washer on the inner face is provided on the screw beneath the head for sealing the apertures 33. Upon tightening the screws the concaved section 28 is drawn against the roofing material which is pressed against the cant with a holding and sealing force while the edge 32 of the section 28 is forced upwardly to provide a seal with the flange 13. After the reglet is secured to the face of the wall 18, a calking material 10 is applied along the top edge to further seal the reglet thereto. The reglet 11 is the sole means for supporting the cant 22 above the roof deck, the marginal upstanding edge of the roofing material and the sealing strip which anchors the roofing material against movements and seals the material to the cant and the reglet. While in FIG. 1, the reglet is illustrated as being secured to the wall by screws 19, in FIG. 2 the reglet 11 is illustrated as being embedded in a concrete wall at the time of pouring the wall.
In FIGS. 3 and 4, a reglet 35 is illustrated as being a strip extruded from an aluminum alloy having a web 36, an upwardly extending bottom flange 37 and a downwardly extending top flange 38 providing a recess 39 which is outwardly presenting. A rearwardly extending flange 41 is of a width to conform to the width of a brick in the inner source of the wall. The flange 41 has an upwardly extending edge flange 42 in engagement with a flange 43 of a sealing plate 44. The plate extends over a joint between the reglet strips which are spaced at least one-eighth inch apart to permit the expansion of the strips when subjected to changing temperatures. The reglet strip may have a length of 10 feet while the sealing plates may be 4 inches in width made from a metal or plastic material and shaped to cover the flanges 41 and 38. The cant 22, the roofing material 26 and the flashing strip 27 are the same as those described with regards to the structure of FIGS. 1 and 2 and are applied in the same manner.
In FIG. 5, a reglet 46 is illustrated which is similar to the reglet 35 of FIG. 3, with the exception that a shorter rearwardly extending flange 47 is employed. The flange 47 has a reversely bent edge flange 48 which at the time of assembly is forced down into clamped relation with an inserted edge of an elastomeric strip 49. This supports and seals the strip 49 onto the edge of the flange 47 and may be used when the reglet strip, such as the strip 35 of FIG. 3, is not available with a flange 41 of such width as to meet that required for the wall thickness. It will be noted that a downward extending lip 51 extends below the flange 37 to provide a greater area of contact with the wall face. The cant 22, the roofing material 26 and the finishing strip 27 are the same as those described hereinabove and are applied in the same manner.
In FIG. 6, a slightly modified reglet 52 is illustrated which is similar to the reglet 46 illustrated in FIG. 5 with the exception that a short length of flange 53 is employed at the top and provided with a T-head 54. This reglet is used when the interior of the wall is dry and requires no seal for the reglet supporting flange. The mortar 55 between the bricks 56 about the flange 53 and head 54 secures the reglet to the face of the wall in the same manner as that illustrated in FIGS. 3 and 5.
In FIG. 7, a further form of support for a reglet 58 is illustrated that wherein the mortar 55 between adjacent bricks 56 secures a reglet 59 therebetween. The reglet 59 may be of any suitable form, the one herein illustrated having a recess 61 and a locking finger 62. The reglet 58 is herein illustrated as being formed from a metal strip to have a web 63, an upwardly extending flange 64 at the bottom and a downwardly extending flange section 65 at the top with an outwardly presenting recess 66 therebetween. The flange section 65 is reversely extended at 67 and further extended to form the flange section 68 disposed normal to the web 63. The free edge of the flange section 68 is reversely formed to provide an angular locking flange 69. The reglet 58 is secured to the face of the wall when the flange section 68 and locking flange 69 are forced into the reglet 59 into locking engagement with the finger 62 as illustrated in the Figure. In this arrangement, the reglet 58 is formed from a sheet of metal although it could also be produced as an extrusion. In the same manner, the reglets of the other Figures could be made of sheet metal instead of extrusions so long as the supporting flanges for the cant 22 and flashing strip 27 are provided. The reglet employed in the manner illustrated and described provides a firm support for the cant, the marginal edge of the roofing material which is retained in firm fixed sealed relation to the cant by the flexible flashing strip which is secured to the material and reglet in pressure relation therewith.
The invention pertains to a reglet for supporting and sealing a cant and a flashing strip to the roofing material which extends over the cant. The reglet is formed in a manner to permit it to be secured to the face of the parapet or wall at a predetermined distance above the roof deck by screws or by embedding it in the concrete or mortar of the wall. The cant is a metal strip which is disposed at an angle when a top vertical flange extends within the reglet and when a bottom horizontal or vertical flange is secured to the roof deck. The reglets come in sections and are spaced at approximately one-eighth inch apart to permit expansion and contraction and a plastic or metal sealing element is placed over the top of the joint and secured in a suitable manner as by the mortar between the bricks. In another form of the invention, a reglet strip is secured within the mortar of the bricks and the reglet strip of the present invention is anchored therein and retained in position solely by the support provided thereby.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The reglet of the present invention is of C-or channel shape and formed to have means by which it is secured to the face of a wall. The various views of the reglet show different types of securing means which may be used to meet different conditions. The reglet 11, illustrated in FIGS. 1 and 2, has a web 12 and outwardly sloping flanges 13 and 14 providing a recess 15 over which the flanges extend. In FIG. 1, the reglet 11 has an elastomeric sealing strip 16 adhered within the recess 17 thereof to extend therebeyond. The sealing strip is compressed against the face of a wall 18 when secured thereagainst by a plurality of securing screws 19. The reglet 11 is mounted above the roof deck 21 in position to support a cant 22 when a reversely extending top flange 23 is engaged over the upwardly extending bottom flange 14. The cant has a bottom flange 24 which is secured to the roof deck by nails 25. A roofing material 26 is placed over the roof deck and extended upwardly with the edges extending into the recess 15 of the reglet to cover the cant. The material is usually layers of felt suitably treated with bitumen and gravel.
A flashing strip 27 may be provided in different forms, the one herein illustrated having an outwardly presenting concaved edge section 28 and an angularly related flange section 29 which is extending outwardly at 31 to provide edge strength. The finishing strip is preferably flexible and is applied to the roofing material by inserting the outer edge 32 of the section 28 into the recess 15 of the reglet in engagement with the inner surface of the flange 13. Apertures 33 are provided through the flange section 29 through which screws 34 extend and through holes punched through the roofing material 26 and the cant 22. A washer 30 having a neoprene washer on the inner face is provided on the screw beneath the head for sealing the apertures 33. Upon tightening the screws the concaved section 28 is drawn against the roofing material which is pressed against the cant with a holding and sealing force while the edge 32 of the section 28 is forced upwardly to provide a seal with the flange 13. After the reglet is secured to the face of the wall 18, a calking material 10 is applied along the top edge to further seal the reglet thereto. The reglet 11 is the sole means for supporting the cant 22 above the roof deck, the marginal upstanding edge of the roofing material and the sealing strip which anchors the roofing material against movements and seals the material to the cant and the reglet. While in FIG. 1, the reglet is illustrated as being secured to the wall by screws 19, in FIG. 2 the reglet 11 is illustrated as being embedded in a concrete wall at the time of pouring the wall.
In FIGS. 3 and 4, a reglet 35 is illustrated as being a strip extruded from an aluminum alloy having a web 36, an upwardly extending bottom flange 37 and a downwardly extending top flange 38 providing a recess 39 which is outwardly presenting. A rearwardly extending flange 41 is of a width to conform to the width of a brick in the inner source of the wall. The flange 41 has an upwardly extending edge flange 42 in engagement with a flange 43 of a sealing plate 44. The plate extends over a joint between the reglet strips which are spaced at least one-eighth inch apart to permit the expansion of the strips when subjected to changing temperatures. The reglet strip may have a length of 10 feet while the sealing plates may be 4 inches in width made from a metal or plastic material and shaped to cover the flanges 41 and 38. The cant 22, the roofing material 26 and the flashing strip 27 are the same as those described with regards to the structure of FIGS. 1 and 2 and are applied in the same manner.
In FIG. 5, a reglet 46 is illustrated which is similar to the reglet 35 of FIG. 3, with the exception that a shorter rearwardly extending flange 47 is employed. The flange 47 has a reversely bent edge flange 48 which at the time of assembly is forced down into clamped relation with an inserted edge of an elastomeric strip 49. This supports and seals the strip 49 onto the edge of the flange 47 and may be used when the reglet strip, such as the strip 35 of FIG. 3, is not available with a flange 41 of such width as to meet that required for the wall thickness. It will be noted that a downward extending lip 51 extends below the flange 37 to provide a greater area of contact with the wall face. The cant 22, the roofing material 26 and the finishing strip 27 are the same as those described hereinabove and are applied in the same manner.
In FIG. 6, a slightly modified reglet 52 is illustrated which is similar to the reglet 46 illustrated in FIG. 5 with the exception that a short length of flange 53 is employed at the top and provided with a T-head 54. This reglet is used when the interior of the wall is dry and requires no seal for the reglet supporting flange. The mortar 55 between the bricks 56 about the flange 53 and head 54 secures the reglet to the face of the wall in the same manner as that illustrated in FIGS. 3 and 5.
In FIG. 7, a further form of support for a reglet 58 is illustrated that wherein the mortar 55 between adjacent bricks 56 secures a reglet 59 therebetween. The reglet 59 may be of any suitable form, the one herein illustrated having a recess 61 and a locking finger 62. The reglet 58 is herein illustrated as being formed from a metal strip to have a web 63, an upwardly extending flange 64 at the bottom and a downwardly extending flange section 65 at the top with an outwardly presenting recess 66 therebetween. The flange section 65 is reversely extended at 67 and further extended to form the flange section 68 disposed normal to the web 63. The free edge of the flange section 68 is reversely formed to provide an angular locking flange 69. The reglet 58 is secured to the face of the wall when the flange section 68 and locking flange 69 are forced into the reglet 59 into locking engagement with the finger 62 as illustrated in the Figure. In this arrangement, the reglet 58 is formed from a sheet of metal although it could also be produced as an extrusion. In the same manner, the reglets of the other Figures could be made of sheet metal instead of extrusions so long as the supporting flanges for the cant 22 and flashing strip 27 are provided. The reglet employed in the manner illustrated and described provides a firm support for the cant, the marginal edge of the roofing material which is retained in firm fixed sealed relation to the cant by the flexible flashing strip which is secured to the material and reglet in pressure relation therewith.
