2 --IMPRo~'EMENTS RELATING TO FL~SHING FOR BUILDINGS
This invention relates to flashing used in buildings to provide a seal between a surface and a member projecting therefrom. The invention is particularly applicable to providing a seal between a 5 roof structure or wall of a buildin~ and a member or structure passing therethrough, projecting therefrom, or adjacent thereto.
Historically, lead or soft malleable metals in 10 sheet form have been used as a flashing material in buildings because of the ease of deforming the material to follow the irregular contour usually presented by the surface of the roofing material, and in the case of lead, because of its ability to be conveniently stretched on 15 site if required. The fashioning of the flashing on site to suit individual situations requires considerable skill by the wurkman in order to ensure an effective seal is achievedl and was a relatively time consuming and therefore costly operation.
2~ Nore recently, there has been a trend towards using rubber or like resilient deformable mat~rials as a substitute for lead, and to prefabricate flashing devices from such materials in a manner to reduce the skill and labour involved in installing same. However, such 25 materials have the disadvantage that due to their resilience they do not readily conform to, and maintain contact with, the surface of the roof or like to which it is to be fitted, without the use of associated components of non-resilient material.
It i6 therefore the object of the present invention to provide an improved flashing product, particularly for use in buildings, which is e~fective in operation, convenient to install, and reduces the skill and labour involved in installation thereof.
With this object in view, there is provided a flashing product incorporating a section made o~ a deformable resilient material and having attached to a ~'~81880 portion of that section a member or members adapted to be manually stretched in at least one direction and when so stretched to be capable of maintaining said portion of resilient material correspondingly stretched.
Conveniently, the adaption of the member to be stretched in one direction is such tha-t compressing of the member may also be effected. In particular the adaption of the member may be such that it may be stretched along one edge and compressed along the opposite edge. This enables a portion of the member to be manually deEormed in the plane thereof into an arcuate or curved form. The member or members are also manually deformable in the direction normal to the plane thereof so that it may be contoured along its length. This contouring of the member may be effected independently or in combination with stretching or compressing of the member.
Conveniently, the member is provided with a plurality of interruption along at least one edge extending substantially in said direction of desired stretch, whereby the member is stretched by increasing the width of the interruption at least along part of the length of the member. Preferably, interruptions are provided along each of two opposite edges of the member with alternate interruption extending from opposite edges of the member.
The interruptions preferably e~tend from the opposite edges more than half the width of the member, or at least overlap one another in the direction of the width of the member.
Preferably, the interruptions extend across the major part oE the width of the member, up to about 75% to 90~ of the width of the member.
Conveniently, the interruption may be of a shape being wider at the edge of the member from which they extend, such as of a V shape.
~LZ~L880 The non-xesilient member may be of a soft metal that is manually deformable such as aluminium, zinc plate, or steel, the steel being preferably galvanised or coated to resi~t corrosion. The member is preferably of 5 a strip form with a thickness of the order of 1/2 to 2 mm, conveniently about 1 mm, to provide the degree of rigidity necessary to hold the resilient material in the stretched or compressed condition.
The non-resilient member may be attached to 10 the de~ormable resilient material by bonding to one face of the resilient material, either in a superimposed or inlaid relation having one face of the member exposed.
Alternatively, the member may be embedded in the resilient material. When the member is embedded in the resilient material it is preferably that at least one face of the member be bonded to the resilient material.
The member or non members may be strips of metal with slots, notches, or slits extending in from one or both longitudinal edges of the ~trip. The degree of ~tretch that the member may achieve without failure i~
increased with the length and member of the slots, notches, or ~lits in the member.
When it i8 required to increase the length of the ~trip or ~heet in the area that the member or members are attached the application of a tension ~orce in the direction of the length of the member will cause the slots or slits to open to increase the width of the slots or slit6, with a resultant stretch of the resilient material spanning the slot or slit. Because of the 30 generally non-resilient nature o~ the material o~ the member or member~ they will retain the stretched state when the tension ~orce i~ released.
It many flashing products, the non-resilient member or members are attached to a marginal edge portion of the product so that the edge portion may be shaped and/or contoured to closely follow the surface to which the flashing product is being ~itted. In such products VZ~8~
the marginal edge portion is req~ired to establish a sealed relation with the surface to which it is being fitted, and so after suitable ~hapin~ of the marginal edge portion, suitable fastenings, such as bolts, screws or ri~ets, are used to secure same together with the resilient material compressed between the non-resilient member and the surface to which the flashing product is fitted.
With slots or slits extending in from opposite edyes of the member or members if the slits or slots are ge~erally equally stretched the edge of the strip will remain generally skraight in the plane of the ~trip.
However, the edge of the strip may be curved by str~tching one edge of the member more than the other, or by stretching one edge and compressing the other.
In one preferred embodiment the non-resilient members are in the form o~ a zig-zag or wave shaped strip. Conveniently, the strips are arranged ~n a nested relation without actual contact between adjacent strips when attached to the resilient material. The greater the spacing o~ the members the greater the maximum dagree of stretch, but the degree of retention of defsrmation may be somewhat reduced.
The use of the zig-zag or wave form in a plurality of member~ attached to a single sheet or strip of resilient material permits stretching in multi directions and deformation in multi orientations.
In one form the flashing product ie a ~lashing ~trip comprising an elongated strip of rubber or like resilient material having along the opposite longitudinal edge portions a metallic 6trip. Each metallic skrip has slits or slot~ extending transversely thereo~ with alternate slit~ or ~lots extending from opposite edges o~
the metalli¢ ~trip. The metallic strips are preferably between about 25 to 35 mm wide and 0.75 to 1.5 mm thick and are embedded in the rubber.
This flashing strip may be used to flash the ~ ~8~
junction between a generally flat s~rface and a non-planar surface, such as the junction of a roof with an upright surface of a wall or structure. The slotted or slit metal strip ena~les the edge portion in which it is embedded to be 5 longitudinally stretched and/or deformed to closely follow the contour of the roof without undue tucks or folds in the flashing strip.
The invention will be more readily understood from the following description of several practical arrangemen~ of 10 products incorporating the presènt invention as illu trated in the accompanying drawings.

The invention will be more readily understood from the following description of several practical arrangemen~ of 10 products incorporating the presènt invention as illu trated in the accompanying drawings.

Referring now to Figure 1 there is illustrated a flashing strip for use in providing a seal between two
3~ inter~ecting surfaces such as a roof and wall or structure projecting therefrom. The flashing strip 10 is comprised of an elongated sheet or strip 20 o~ rubber or like resilient material having suitable physical properties for outdoor use, particularly extended 35 exposure to sunlight. Each longitudinal marginal edge portion 22 of the 6heet 20 has a metal strip 21 bonded to the 6urface thereof on the same side of the ~heet. Each metal strip 21 has a ~eries of slits or 610ts 23, 2~
therein extending inwardly from the respective edge6 25, ~~ ~ 88~
26 of the strip. The con~truction of the strip 21 is more clearly shown in Figure 2 wherein the same reference numeral as used in Figure 1 apply.
The strip 21 is manufactured as a continuous 5 band with the slots 23 and 24, extending from the opposite edges 25 and 26, alternating. At the junction of the 610ts with the edges of the strip the corners are radiused at 30 to reduce the risk that the corners may pierce the rubber sheet, and ~o create a leak or even ~' 10 promote tearing of the rubber sheet. Also the base of the ~lots 23 and 24 are radiused at 31 to produce the risk o~ the metal of the strip tearing when the strip is stretched.
In a typical arrangement of th~ flashing strip 15 10 the strips 21 are made o~ an aluminium alloy o~ a thickness of 1 mm and a width of 25 mm. The slots 23, 25 are of a width of 1.5 mm and a length of 18 mm. The rubber of which the sheet 20 i8 preferably an EPDM rubber with a hardness preferable less than 40 Durometer.
The flashing 6trip 10 as shown in Figure 1 has the strips 21 bonded to the surface of the rubber sheet 20, and this is achieved by applying a coating of bond primer to at ~east the surface of the strip that will contact the sheet 20, and then bring the primed surface 25 of the strips into contact with the 6heet 20 in the uncured 6tate. Preferably the sheet and ~trips are pressed together such as by passing through rollers to inlay the strips into the sheet with the rubber filling the 810t8 23, 24 in the strips. The resulting assembly 30 is then cured.
It is to be understood that a flashing strip as shown in Figure 1 may al~o be made with the metal strips 23 and 24 completely embedded in the marginal edge portions of the rubber ~heet 20. This construction i5 35 particularly desirable for aesthetic reasons. In many applications of the flashing strip 10 the degree of stretching of the metal strip may vary from one location L8~0 to another, and the resultant irregular appearance of the metal strips as would be exhibited by the construction shown in Figure 1 may be considered objectionable. ~his irregularity is concealed if the strips 23 and 24 are completely embedded in the rubber sheet.
The construction o~ the flashing strip 10 with embedded metal strips 21 may be effected by laying up the primer coated metal strips 21 between layers of uncured rubber and holding them in assembly under pressure and 10 heating to effect curing. An alternative method is to extrude the rubber ~heet 20 with the metal fitrips 23 and 24 embeddeA in the marginal edge portions of the extruded sheet and then cure the resulting assembly. The extruded assembly can be rolled and cured in an autoclave, and so renders this method of construction advantageous for high volume production.
As previously described the flashing strip 10 has a slotted metal strip 21 in each ~arginal edge portion, however in some applications a slotted metal strip may be located in only one marginal edge portion, the opposite edge portion may be wholly of rubber or may hav2 a solid un-slotted metal trip therein. The un-slotted strip may be bonded to the surface of or embedded in the rubber sheet in the manner as previously described in relation to the slotted strips.
When the flashing strip 10 as described above with reference to Figures 1 and 2 is in use it i~
frequently necessary for part of one of the marginal edge portions to increased in length such as when the flashing strip is reguired to extend around a corner of a struature projecting from a roof, such as a skylight structure. This use o~ the flashing strip is illustrated in Figure 6 o~ the accompanying drawing. The sXylight structure 35 ~part only shown) projects from the sheet metal roof 36 having a series of sti~fening ridges 37 extending up the slope of the roof. It is to be understood that only part of the skylight ~tructure is ~ L281~80 ~ 9 _ shown in ~igure 6 representing one corner o~ that structure.
~ he marginal edge portion 38 of the flashing strip 40 has a continuous unslotted metal strip 41 bonded 5 thereto, as edge portion 38 is not required to be stretched or compressed in order to be fitted around the perimeter of the skylight structure. The marginal edge portion 38 is secured to the skylight structure 35 at regular intervals by screw~ 42 so that the rubber is compressed between the strip 41 and to skylight structure 35 to provide a weather tight seal.
The rubber sheet portion 43 of the flashing strip curve outwardly and downwardly from the marginal edge p~rtion 38 to the opposite marginal edge portion 45 15 which lies on the surface of the roof sheet 36. The metal strip 44 of the edge portion 45 is provided with a series of slots 46 along its inner edge 47 and series of 610ts 48 along its outer edge 49. The slots 46 and 48 - are of the form and are arranged as previously descr~bed 20 in respect to the 610ts 23 and 24 as shown in Figures 1 and 2. In those areas of the edge portion 45 that are straight and li~ flat on the roof sheet, as indicated at 50, the slots 46 and 48 are not ~tretched or compressed and so the slots are of uniform width throughout their 25 length, that is as formed.
In the corner area 51 the marginal portion 45 must be increased in length to accommodate the arcuate path it must follow around the corner of the skylight ~tructure while remaining flat on the sur~ace o~ the roof 30 sheet. This increase in length i5 obtained by stretching the metal strip 44 by opening the slots 46 and 48 with the outer 610ts 48 being opened wider than the inner slots 46 to establish the curved shape. Because of the relative ~trength o~ the metal strip 44 and the rubber 35 sheet 43, o~ce the metal ~trip q4 and the portion of the rubber sheet, attached thereto have been stretched the strip 44 will retain its etretched state and also will 38~
hold the attached portion of the ru~ber sheet in the stretched state.
In order for the marginal portion 45 to pass over the ridge 37 in the area 52 there must also be an increase in the length of the marginal portion 45 by a stretching of the metal strip 44. As the strip is not required to follow a curved path in this area, the inner and outer slots 46 and 4~ are each opened by generally the same amount.
The above stretching and bending of the slotted metal strip 46 enables the marginal portion 45 to be shaped to be passed around corners and over ridges or through valleys, and maintain close ~ace to face contact with the roof sheet 36. Accordingly, when appropriately spaced ~crews 54 are applied to fasten the marginal edge portion 45 to the roof sheet the rubber is compressed between the strip 44 and the roof sheet 36 to provide a weather tight seal therebetween.
The ability to increase the length of the marginal edge portion of the flashing strip in ~elected location, and to selected degrees, enablies the flashing strip to be fitted to non planar and irregular surface and in doing so establish an e~fective ~ealing relation therewith. In addition the ~tretching and bending of the flashing strip is achieved without development of major folds, pleats or tuck~ in the rubber ~heet that may provide an area for collection of water, and present an untidy appearance.
Figure 4 in the drawing illustrates a sealing device specifically designed to prov$de a seal between a pipe or duct projecting through a roo~ made of ridged sheet material. The seal device comprises a ~lange 9 of resilient readily de~ormable material, such as natural or synthetic rubber, having an integral sleeve 11 extending from the upper face of the flange. The sleeve 11 has a tapered portion 18 tapering toward the upper free end 12, and at the lower end has a generally cylindrical portion 12~3~8~30 13 that connects the tapered portion 18 to the flange 9.
The flange 9 has a aperture therein, (not shown) that is co-axial with and communicates with the bore of the sleeve 11. In use the pipe or duct will pass through the aperture and sleeve.
The wall of the cylindrical portion 13 is preferably somewhat thicker than the adjacent portion of the flange 9 and taperad portion 18 to provide greater resistance to distortion in use.
The junction areas b0tween the cylindrical portion 13 and the flange 9 and tapered portion 19 are sufficiently flexible to accommodate misalignment of the cylindrical portion relative to the other parts of the seal device, as may be necessary in normal use. Spaced along the tapered portion 19 are a plurality of external ridges 14 denoting where the sleeve may be cut off to suit elongate members of different diameters. The ridges also provide a reinforce-ment about the edge of the open end of the sleeve so formed.
The general construction of the sleeve 11 with another orm of flange has been proposed in U.S. Patent No.
therein extending inwardly from the respective edge6 25, ~~ ~ 88~
26 of the strip. The con~truction of the strip 21 is more clearly shown in Figure 2 wherein the same reference numeral as used in Figure 1 apply.
The strip 21 is manufactured as a continuous 5 band with the slots 23 and 24, extending from the opposite edges 25 and 26, alternating. At the junction of the 610ts with the edges of the strip the corners are radiused at 30 to reduce the risk that the corners may pierce the rubber sheet, and ~o create a leak or even ~' 10 promote tearing of the rubber sheet. Also the base of the ~lots 23 and 24 are radiused at 31 to produce the risk o~ the metal of the strip tearing when the strip is stretched.
In a typical arrangement of th~ flashing strip 15 10 the strips 21 are made o~ an aluminium alloy o~ a thickness of 1 mm and a width of 25 mm. The slots 23, 25 are of a width of 1.5 mm and a length of 18 mm. The rubber of which the sheet 20 i8 preferably an EPDM rubber with a hardness preferable less than 40 Durometer.
The flashing 6trip 10 as shown in Figure 1 has the strips 21 bonded to the surface of the rubber sheet 20, and this is achieved by applying a coating of bond primer to at ~east the surface of the strip that will contact the sheet 20, and then bring the primed surface 25 of the strips into contact with the 6heet 20 in the uncured 6tate. Preferably the sheet and ~trips are pressed together such as by passing through rollers to inlay the strips into the sheet with the rubber filling the 810t8 23, 24 in the strips. The resulting assembly 30 is then cured.
It is to be understood that a flashing strip as shown in Figure 1 may al~o be made with the metal strips 23 and 24 completely embedded in the marginal edge portions of the rubber ~heet 20. This construction i5 35 particularly desirable for aesthetic reasons. In many applications of the flashing strip 10 the degree of stretching of the metal strip may vary from one location L8~0 to another, and the resultant irregular appearance of the metal strips as would be exhibited by the construction shown in Figure 1 may be considered objectionable. ~his irregularity is concealed if the strips 23 and 24 are completely embedded in the rubber sheet.
The construction o~ the flashing strip 10 with embedded metal strips 21 may be effected by laying up the primer coated metal strips 21 between layers of uncured rubber and holding them in assembly under pressure and 10 heating to effect curing. An alternative method is to extrude the rubber ~heet 20 with the metal fitrips 23 and 24 embeddeA in the marginal edge portions of the extruded sheet and then cure the resulting assembly. The extruded assembly can be rolled and cured in an autoclave, and so renders this method of construction advantageous for high volume production.
As previously described the flashing strip 10 has a slotted metal strip 21 in each ~arginal edge portion, however in some applications a slotted metal strip may be located in only one marginal edge portion, the opposite edge portion may be wholly of rubber or may hav2 a solid un-slotted metal trip therein. The un-slotted strip may be bonded to the surface of or embedded in the rubber sheet in the manner as previously described in relation to the slotted strips.
When the flashing strip 10 as described above with reference to Figures 1 and 2 is in use it i~
frequently necessary for part of one of the marginal edge portions to increased in length such as when the flashing strip is reguired to extend around a corner of a struature projecting from a roof, such as a skylight structure. This use o~ the flashing strip is illustrated in Figure 6 o~ the accompanying drawing. The sXylight structure 35 ~part only shown) projects from the sheet metal roof 36 having a series of sti~fening ridges 37 extending up the slope of the roof. It is to be understood that only part of the skylight ~tructure is ~ L281~80 ~ 9 _ shown in ~igure 6 representing one corner o~ that structure.
~ he marginal edge portion 38 of the flashing strip 40 has a continuous unslotted metal strip 41 bonded 5 thereto, as edge portion 38 is not required to be stretched or compressed in order to be fitted around the perimeter of the skylight structure. The marginal edge portion 38 is secured to the skylight structure 35 at regular intervals by screw~ 42 so that the rubber is compressed between the strip 41 and to skylight structure 35 to provide a weather tight seal.
The rubber sheet portion 43 of the flashing strip curve outwardly and downwardly from the marginal edge p~rtion 38 to the opposite marginal edge portion 45 15 which lies on the surface of the roof sheet 36. The metal strip 44 of the edge portion 45 is provided with a series of slots 46 along its inner edge 47 and series of 610ts 48 along its outer edge 49. The slots 46 and 48 - are of the form and are arranged as previously descr~bed 20 in respect to the 610ts 23 and 24 as shown in Figures 1 and 2. In those areas of the edge portion 45 that are straight and li~ flat on the roof sheet, as indicated at 50, the slots 46 and 48 are not ~tretched or compressed and so the slots are of uniform width throughout their 25 length, that is as formed.
In the corner area 51 the marginal portion 45 must be increased in length to accommodate the arcuate path it must follow around the corner of the skylight ~tructure while remaining flat on the sur~ace o~ the roof 30 sheet. This increase in length i5 obtained by stretching the metal strip 44 by opening the slots 46 and 48 with the outer 610ts 48 being opened wider than the inner slots 46 to establish the curved shape. Because of the relative ~trength o~ the metal strip 44 and the rubber 35 sheet 43, o~ce the metal ~trip q4 and the portion of the rubber sheet, attached thereto have been stretched the strip 44 will retain its etretched state and also will 38~
hold the attached portion of the ru~ber sheet in the stretched state.
In order for the marginal portion 45 to pass over the ridge 37 in the area 52 there must also be an increase in the length of the marginal portion 45 by a stretching of the metal strip 44. As the strip is not required to follow a curved path in this area, the inner and outer slots 46 and 4~ are each opened by generally the same amount.
The above stretching and bending of the slotted metal strip 46 enables the marginal portion 45 to be shaped to be passed around corners and over ridges or through valleys, and maintain close ~ace to face contact with the roof sheet 36. Accordingly, when appropriately spaced ~crews 54 are applied to fasten the marginal edge portion 45 to the roof sheet the rubber is compressed between the strip 44 and the roof sheet 36 to provide a weather tight seal therebetween.
The ability to increase the length of the marginal edge portion of the flashing strip in ~elected location, and to selected degrees, enablies the flashing strip to be fitted to non planar and irregular surface and in doing so establish an e~fective ~ealing relation therewith. In addition the ~tretching and bending of the flashing strip is achieved without development of major folds, pleats or tuck~ in the rubber ~heet that may provide an area for collection of water, and present an untidy appearance.
Figure 4 in the drawing illustrates a sealing device specifically designed to prov$de a seal between a pipe or duct projecting through a roo~ made of ridged sheet material. The seal device comprises a ~lange 9 of resilient readily de~ormable material, such as natural or synthetic rubber, having an integral sleeve 11 extending from the upper face of the flange. The sleeve 11 has a tapered portion 18 tapering toward the upper free end 12, and at the lower end has a generally cylindrical portion 12~3~8~30 13 that connects the tapered portion 18 to the flange 9.
The flange 9 has a aperture therein, (not shown) that is co-axial with and communicates with the bore of the sleeve 11. In use the pipe or duct will pass through the aperture and sleeve.
The wall of the cylindrical portion 13 is preferably somewhat thicker than the adjacent portion of the flange 9 and taperad portion 18 to provide greater resistance to distortion in use.
The junction areas b0tween the cylindrical portion 13 and the flange 9 and tapered portion 19 are sufficiently flexible to accommodate misalignment of the cylindrical portion relative to the other parts of the seal device, as may be necessary in normal use. Spaced along the tapered portion 19 are a plurality of external ridges 14 denoting where the sleeve may be cut off to suit elongate members of different diameters. The ridges also provide a reinforce-ment about the edge of the open end of the sleeve so formed.
The general construction of the sleeve 11 with another orm of flange has been proposed in U.S. Patent No.
4,664,390,issued to D.G.Houseman on May 12,1987 and which was developed within the same corporation as the present invention.
The opposite marginal edge portions 15 and 16 of the flange 9 have bonded thereto the metal strips 17 that extend the length of the flange. The metal strips 17 are each of the construction of the strips 21 as previously described with reference to Figures 1 and 2 of the drawing and may be stretched, compressed, or contoured in the same manner.
The metal strips 17 are bonded to the upper surface of the flange 9 in the embodiment as shown, however if desired may be embedded within the flange as previously referred to in respect of other embodiments.
In use the seal device as shown in Figure 4 is fitted to a pipe or duct extending through a roof sheet by cutting the sleeve 11 off at the ridge 14 appropriate ~'~81~80 to the size of the pipe or duct, and inserting the pipe or duct through the flange 9 and sleeve 11 so the flange will lie on the upper surface of the roof sheet. As is known, roof sheets have spaced longitudinal ribs or ridges to impart the required strength thereto, and the flange 9 of the sealing device must be attached in a sealed relation thereto. The metal strips 17, which extend across these ribs when the seal device is assemb]ed to the pipe or duct, may be stretched and contoured so that the edge portions 15 and 16 of the flange 9 may closely follow the contour of the roof without resulting in substantial folds and disturbances in the area of the flange between the edge portions 15 and 16 and the sleeve 11. Screws, rivets or like fastenings are applied to attach the edge portions to the roof sheet so the rubber of the flange 9 is compressed between the respective strips 17 and the roof sheet to establish the weather tight seal therebetween.
No metal strip is attached to the edge portions 7 and 8 of the flange 9 so as to contribute to the freedom of movement of the flange material to avoid the formation of folds during installation. However, separate metal strips not shown are preferably fitted using suitable fastenings to compress the edge portions 7 and 8 adjacent the roof sheet after fixing of the metal strips 17 to the roof sheet has been completed.
An alternative form of seal device is shown in Figure 5, which is similar to that described above with reference to Figure 4, but has a relatively narrow annular flange 55 and is an adaption of the present invention to the seal device the subject of U.S. Patent No. 4,333,660. The sleeve 56 is of the same general form as described with reference to Figure 4 and will not be further described.
Between the lower end of the sleeve 56 and the flange 55 is a re-entrant skirt 57 which provides a substantial degree of flexibility between the sleeve and the flange to accommodate misalignment encountered when fitting the seal device to a ~xa~s~
pipe projecting through a roof. This flexibility reduces the degree of distortion of the sleeve and flange that may otherwise be necessary to accommodate such misalignment.
The annular flange 55 has a lower portion S9 of S rubber formed integral with the skirt 57 and an upper metal strip 58 bonded to the upper face of the lower portion 59.
In an alternative construction the metal strip 58 may be embedded in the rubber of the lower portion. The metal strip 58 is of an annular shape complementary to the lower portion 59 and has slots 60 extending in from each of the inner and outer edges of the strip. The form and arrangement of the slots 60 are the same as previously described in respect of the metal strips illustrated in Figures 1 and 2, and provide the same capacity to be stretched or compressed to impart a desired shape or contour to the flange 55 when being installed to a non-planar roof or other surface. The flange is secured in position by suitably located fastenings such as screws, bolts or rivets that pass through the flange 55.
The metal strip 58 as incorporated in the seal device shown in Figure 5 may be stamped from a flat sheet of metal with the slots 60 being formed in the same operation as the profile of the straight form and then further worked into the annular shape. The rubber flange 55 may have the metal strip 58 bonded thereto as a separate operation after final forming of the flange, or the metal strip 58, in an annular form may be located in a die and the flange 55 and sleeve 56 then moulded in that die to thereby bond the metal strip to the flange.
The metal strip 21 as previously described may be produced in a stamping operation, or by suitable rolls that will form the series of slots of the shape and formation previously described. Alternatively, a wire or rod of the suitable metal may be formed into a sinuate shape and then the wire or rod is pressed flat as by passing through rollers to ~orm a strip as described with reference to ~i~8~8~
Figure 2. The pitch and amplitude of the sinuate shape is selected, having regard to the wire or rod diameter, to give the required slot form and spacing after being flattened.
In some constructions the sinuate wire or rod may be used in an un-flattened state.
It will be appreciated that the m0tal strip may be formed by other known metal working techniques and the invention is not limited to the specific techniques discussed herein. Also the form of the strip and the interruption therein may take forms, other than those specifically referred to herein, that will impart the non-resilient deformability to the strip to permit the manual stretching and compressing thereof.
Figure 7 of the drawings show a rubber strip 65 having two strips 66 of non-resilient material bonded to one face thereof. The strips 66 are each of a sinuate form and are arranged in a nesting relationship, but spaced so that the strips are not in contact with each other, thus forming a sinuate band 67 of rubber between the two metal strips 66.
In this construction, in addition to each strip 66 being stretchable in the direction of the length of the strip, by appropriate variation in the deformation of each strip 66 a degree of shaping of the rubber strip 65 in the transverse direction can be obtained. It is also to be understood that the number of metal strips arranged in the nested relation may be increased so as to form a sheet rather than a strip of rubber, that may be manually deformed and will retain that deformed condition.
The opposite marginal edge portions 15 and 16 of the flange 9 have bonded thereto the metal strips 17 that extend the length of the flange. The metal strips 17 are each of the construction of the strips 21 as previously described with reference to Figures 1 and 2 of the drawing and may be stretched, compressed, or contoured in the same manner.
The metal strips 17 are bonded to the upper surface of the flange 9 in the embodiment as shown, however if desired may be embedded within the flange as previously referred to in respect of other embodiments.
In use the seal device as shown in Figure 4 is fitted to a pipe or duct extending through a roof sheet by cutting the sleeve 11 off at the ridge 14 appropriate ~'~81~80 to the size of the pipe or duct, and inserting the pipe or duct through the flange 9 and sleeve 11 so the flange will lie on the upper surface of the roof sheet. As is known, roof sheets have spaced longitudinal ribs or ridges to impart the required strength thereto, and the flange 9 of the sealing device must be attached in a sealed relation thereto. The metal strips 17, which extend across these ribs when the seal device is assemb]ed to the pipe or duct, may be stretched and contoured so that the edge portions 15 and 16 of the flange 9 may closely follow the contour of the roof without resulting in substantial folds and disturbances in the area of the flange between the edge portions 15 and 16 and the sleeve 11. Screws, rivets or like fastenings are applied to attach the edge portions to the roof sheet so the rubber of the flange 9 is compressed between the respective strips 17 and the roof sheet to establish the weather tight seal therebetween.
No metal strip is attached to the edge portions 7 and 8 of the flange 9 so as to contribute to the freedom of movement of the flange material to avoid the formation of folds during installation. However, separate metal strips not shown are preferably fitted using suitable fastenings to compress the edge portions 7 and 8 adjacent the roof sheet after fixing of the metal strips 17 to the roof sheet has been completed.
An alternative form of seal device is shown in Figure 5, which is similar to that described above with reference to Figure 4, but has a relatively narrow annular flange 55 and is an adaption of the present invention to the seal device the subject of U.S. Patent No. 4,333,660. The sleeve 56 is of the same general form as described with reference to Figure 4 and will not be further described.
Between the lower end of the sleeve 56 and the flange 55 is a re-entrant skirt 57 which provides a substantial degree of flexibility between the sleeve and the flange to accommodate misalignment encountered when fitting the seal device to a ~xa~s~

The annular flange 55 has a lower portion S9 of S rubber formed integral with the skirt 57 and an upper metal strip 58 bonded to the upper face of the lower portion 59.
In an alternative construction the metal strip 58 may be embedded in the rubber of the lower portion. The metal strip 58 is of an annular shape complementary to the lower portion 59 and has slots 60 extending in from each of the inner and outer edges of the strip. The form and arrangement of the slots 60 are the same as previously described in respect of the metal strips illustrated in Figures 1 and 2, and provide the same capacity to be stretched or compressed to impart a desired shape or contour to the flange 55 when being installed to a non-planar roof or other surface. The flange is secured in position by suitably located fastenings such as screws, bolts or rivets that pass through the flange 55.
The metal strip 58 as incorporated in the seal device shown in Figure 5 may be stamped from a flat sheet of metal with the slots 60 being formed in the same operation as the profile of the straight form and then further worked into the annular shape. The rubber flange 55 may have the metal strip 58 bonded thereto as a separate operation after final forming of the flange, or the metal strip 58, in an annular form may be located in a die and the flange 55 and sleeve 56 then moulded in that die to thereby bond the metal strip to the flange.
The metal strip 21 as previously described may be produced in a stamping operation, or by suitable rolls that will form the series of slots of the shape and formation previously described.
