Definitions

  • the present invention relates to a connector element for use in a flashing assembly for roof windows mounted side-by-side comprising at least two flashing members each having a leg intended for being arranged so that it projects away from the window frame, where the connector element has an exterior side intended for facing the exterior in the mounted state, an interior side intended for facing the roof in the mounted state, a first end intended for facing the window, a second end intended for facing away from the window, two side walls extending between the first and second ends and forming a gutter extending in a longitudinal direction and being open towards the exterior side, and at least two flanges projecting from the interior side adapted for engagement with a mounting bracket arrangement including at least two mounting brackets associated with two different roof windows mounted side-by-side, and where the connector element comprises at least one point of attachment adapted for engagement with an engagement section of a flashing member.
  • the invention further relates to a connector set including such a connector element.
  • Such a connector element is known from WO 2015/028030 A1 and has proven to work very well when mounting flashing assemblies on groups of windows with frames made from glass fibre reinforced polymers or materials, which are not well suited for receiving screws.
  • This connector element is, however, only suitable for very specific installation situations and requires precise mounting.
  • WO 2015/028030 A1 does suggest that the connector element is slightly elongate by means of a simple adaptor element, which is wrapped around the interior side and the side walls of the connector element at its second end and is attached by means of two bendable tongues which are folded over small recesses in the edges of the side walls and into the gutter. The adaptor thereby extends as a straight elongation of the gutter.
  • each side wall is provided with a, preferably elongated, attachment element on an outer side facing away from the gutter, said attachment elements being adapted for engagement with a corresponding attachment element on an extension element or with corresponding attachment members of an adaptor element.
  • the attachment element preferably comprises a first series of attachment members, said first series being preferably a part of a second larger series of attachment members.
  • an extension element allows the use of a standard connector element e.g. in installation situations, where the windows are mounted on an upstand, which is wider than usual, and where the flashing members therefore have to project relatively far from the outer side of the window in order to cover the upstand.
  • Providing the attachment elements on the outer sides of the side walls provides for making the extension element of a mouldable material such as a plastics material since bendable tongues, which would require the material to be metal such as steel or aluminium, are avoided.
  • the extension element may be attached at several points with a mutual distance in the longitudinal direction whereby a more secure fastening is obtained in relation to bending forces acting on the assembled connector element and extension element e.g. due to wind load or the weight of snow lying on flashing members supported by the connector element and the extension element.
  • the extension element may be attached to several attachment members at each side thus providing a particularly reliable interconnection of the connector element and the extension element.
  • attachment members on an outer side of the connector element facing away from the gutter entails that they do not hinder the passage of water through the gutter when the connector element also serves drainage purposes as will described in detail below.
  • flashing members may be arranged with flanges projecting over the edges of the side walls and into the gutter in order to provide an interconnection between the flashing members and the connector element without colliding with the attachment members.
  • the attachment members may be embodied in several ways including the use of a hook and loop type fasteners, but will often include male and female parts on the connector element and on an extension element or adaptor element, respectively, or vice versa.
  • the attachment elements are adapted for snap-locking engagement. This may be achieved either by virtue of a snap-locking engagement between the actual attachment elements or by force-fitting the engagement between the extension element or adaptor element and the connector element, so that one set of attachment elements snaps onto the other and passively secures the engagement between the two elements.
  • the extension element is made with two side walls extending substantially in parallel with the side walls of the connector element in a mounted state and forming a gutter extending in continuation of the gutter of the connector element in a mounted state, a first end of the extension element being adapted for engaging the second end of the connector element and a second end of the extension element being adapted for facing away from the connector element, and where the width of the gutter of the extension element at its first end is larger than the width of the connector element at its second end, so that the first end of the extension element may embrace the second end of the connector element in the mounted state.
  • This embodiment of the extension element may, however, also be used with other types of attachment elements.
  • one of the attachment elements or attachment members and the corresponding attachment elements or attachment members comprise protrusions protruding from the respective side wall and the other of the attachment elements or attachment members and the corresponding attachment elements or attachment members comprise recesses in the respective side wall.
  • the attachment members on the connector element have the shape of truncated cones, which are fitting into corresponding hollow cones on side walls of the extension element or adaptor element. If making one or both sets of cones elastic by forming them from an elastic material or by providing slots or the like allowing sections or the cones to yield, a snap-locking engagement between the cones may be provided.
  • cone-shaped attachment members may advantageously be obliquely truncated so that the side of the cone facing the exterior side of the connector element extend further from the outer side of the side wall than the side of the cone facing the interior side of the connector element.
  • the oblique end surface of the truncated cone may then serve as a guide for the attachment of the extension element or adaptor element by gradually forcing the side walls of the extension element or adaptor element aside during mounting thereof until the attachment members on the connector element snaps into the attachment members on the extension element or adaptor element.
  • a section of one or both side walls of the extension element at the first end may be offset so that the section of the gutter in the extension element extending along the offset section(s) has a larger width than the rest of the gutter in the extension element. Offsetting sections, particularly adjacent to the free edges of the side walls, will help guide the connector element into the extension element and/or prevent that the side walls of the extension element are exposed to too high bending forces when being forced over the attachment members on the connector element as will also be described with reference to the drawing below.
  • the embracement may per se provide for overall rigidity of the connected elements provided an attachment element is positioned centrally relative to the overlap.
  • Such attachment element may be substantially punctual, i.e. not elongated.
  • the provision of an elongated attachment element will per se provided for, and will thus add to, the overall rigidity of the connected elements.
  • the attachment members should be of a design which provides them with sufficient strength to maintain the interconnection of the connector element and the extension element even when the flashing assembly is subjected to heavy loads, such as high wind loads or the weight of snow. It is, however, possible to add a reinforcement element adapted for reinforcing the connection.
  • a reinforcement element is arranged to extend along the connector element and the extension element in the mounted state, and the connector element and/or the extension element is/are provided with further attachment members adapted for providing a connection to the reinforcement element.
  • the further attachment members may simply be holes extending through the connector element and the extension element and being aligned in the mounted state so that a bolt or like fastener may be passed through them, but other types of attachment members such as snap-locking members or hook-and-loop type fasteners may also be employed, or the reinforcing element may be attached using glue, adhesive or even welding.
  • the reinforcement element may be a simple strip of material or have a more complex shape, including a gutter-shape element adapted to embrace the outer and interior sides of the connector element and the extension element at least over a section of their length. It may be of metal, plastic or any other material having a sufficient bending strength to stabilize the joint between the connector element and the extension element.
  • the connector element according to invention may be provided one or more, preferably two or more, raised sections in the gutter, said raised section(s) being adapted for serving as point(s) of attachment for an engagement section of a flashing member as is also known from the connector element described in WO 2015/028030 A1 .
  • Providing the points of attachment on raised sections means that they are kept a distance from any water in the gutter, thus both protecting the fasteners used for securing flashing members to the connector element and reducing the risk of water entering the construction at the points of attachment.
  • the raised sections may be simple cylindrical bosses, but more complex designs are also possible, for example to provide a larger area of support for the flashing member or a larger contact area with the bottom of the gutter.
  • the connector element may nonetheless be provided with three or more raised sections. This will allow the same connector element to be used for several different installation situations by using one pair of raised section in one installation situation and another pair in another installation situation.
  • one or more of the raised sections may be mutually interconnected or connected to a bottom of the gutter by a wall extending substantially in parallel to one or both side walls.
  • the connector element with one or two raised section, but in order to increase the versatility of the connector element three or more raised sections may be provided corresponding to different installation situations. During mounting only the raised section, which are positioned suitably for the specific installation situation, are used.
  • extension element which may also be provided with raised section of the same or similar type as the connector element.
  • Another way of increasing the versatility of the connector element is to provide it with weakenings and/or cutting guides in the side walls and/or bottom of the gutter adapted for aiding in the removal of a part of the connector element.
  • the connector element may easily be shortened and adapted for installation purposes, where the standard length it too long. Removing part of the connector element may involve the removal of one or more raised sections, which are not needed for the installation situation in question.
  • the extension element may also be provided with such weakenings and/or cutting guides in order to be able to shorten it, even if the connector element is not provided with weakenings or cutting guides.
  • the engagement between the attachment members of the adaptor element and the connector element is adapted for allowing the adaptor element to be adjusted to different angular positions relative to the longitudinal direction about an axis, which is substantially perpendicular to the side walls of the connector element.
  • the engagement between the attachment members of the adaptor element and the connector element is adapted for allowing the adaptor element to rotate about an axis, which is substantially perpendicular to the side walls of the connector element.
  • the adaptor element is, like the connector element may be, provided with one or more raised section(s), said raised section(s) being adapted for serving as point(s) of attachment for an engagement section of a flashing member.
  • one or more such raised section(s) are of an elongate configuration allowing several possible points of attachment for an engagement section of a flashing member. This enhanced the versatility of the connector set.
  • Fig. 1 shows two roof windows 1 mounted side-by-side on a so-called upstand 2, which is a load-bearing frame construction typically formed on a roof 211 with limited inclination as described for example in EP 2472027 A2 . It is, however, to be understood that the present invention works equally well in other installation situations, where the flashing assembly and mounting brackets are of a different configuration.
  • each window 1 has an upper part 11 and a lower part 12 at either end of the window relative at what is herein arbitrarily defined as a longitudinal direction. It is noted that in Fig. 1 , line X is extending along said longitudinal direction.

  • the lower flashing members 41 each comprises a first leg 411 and a second leg 412.
  • the mounting brackets 3 are in the present embodiment of a design, known per se from WO 2015/028030 A1 , with two plate members 31, 32 extending in parallel away from the window frame 14 and these plate members are separated by intermediate members in the form of tubular spacer members 331 ( Figs. 3 and 4 ) extending between holes 332 in the respective plate members.
  • the spacer members may be used as guides for bolts (not shown) used for interconnection the mounting brackets of the two windows mounted side-by-side to contribute to the stability of the group of windows or as points of attachment for other parts of the window such as operators (not shown) arranged on the outer side of the window frame.
  • the side plates 31, 32 of the mounting brackets 3 each comprise a proximal side plate 31, which is proximal relative to a longitudinal vertical centre plane of the window (not shown), and a distal side plate 32, which is distal relative to said longitudinal vertical centre plane.

  • FIG. 23 shows a section of an extreme end of the extension element 7 and the adaptor element 6, the picture would be identical if the section had been through the extreme end of the second end of the connector element 5, 5' carrying the adaptor element 6 since the extreme ends of the connector element 5, 5' and the extension element 7, respectively, are identical as it will be explained below.
  • the attachment members 572, 772a are round in a cross-section parallel to the respective side wall 52, 52', and the openings 623 are also round, the engagement between the attachment members 572a, 772a and the corresponding attachment members, i.e. the openings 623, allows the adaptor element 6 to rotate around an axis 624 extending through the openings 623 in the respective flanges 622, i.e. an axis 624 perpendicular to the longitudinal direction of the adaptor element 6 as well as of the connector element 5, 5' or the extension element 7, and thus the axis 624 is substantially perpendicular to the side walls 52, 52' of the connector element 5, 5'.
  • the adaptor element 6 may be adjusted to different angular positions relative to said longitudinal directions, as it is e.g. seen from a comparison of Figs. 12 and 13 and of Figs. 14 and 15 , respectively.
  • the side walls 52, 52' are not exactly parallel but diverges slightly from the bottom of the gutter 53. Accordingly, the language "substantially perpendicular to the side walls” should be interpreted as referring to an average.
  • attachment members 572 are shaped as obliquely truncated cones a wedging effect is obtained when the adaptor element 6 is assembled with the connector element 5, 5' (or the extension element 7, as will be explained) by lowering the connector element 5, 5', interior side 512, 512' first, in between the flanges 622 of the adaptor element 6, whereby the flanges 622 and the side walls 52, 52' are elastically deformed until the attachment members 572 on the opposite side walls 52, 52' snap into the openings 623 in the likewise opposite flanges 622, the flanges 622 and side walls 52, 52' returning to their original positions.
  • a wedging effect might be obtained by obliquely recessing the inner sides of the flanges 622 adjacent the openings 623, which the attachment members 572 will slide over and pass when the connector element and the adaptor element are assembled.
  • attachment elements might be provided on the side walls 52, 52' and the flanges 622, which would actively secure their mutual engagement.
  • two raised sections 631, 633 are provided to provide for points of attachment for the flashing members supported by the adaptor element 6.
  • a single point of attachment is provided by a first raised section 631 having a round through hole 632 for receiving a screw or like fastener.
  • a second raised section 633 has an elongated through hole 634 and thus provides a multiplicity of points of attachment within the extension of the elongated hole 634.
  • the short adaptor element 6' is seen to be mainly identical to the long adaptor element 6 except for the fact that its part forming the gutter 61' is shorter than the corresponding part of the long adaptor element 6 and accordingly the first raised section 631 has been left out.
  • the flanges 622 of the short adaptor element 6' are identical to the flanges of the long adaptor element 6.
  • the short adaptor element 6' may be used in installation situation where the long adaptor element 6 would be too long.
  • the present invention provides an extension element 7 an embodiment of which is shown in Figs. 6 , 12-18 and 22-23 .
  • the extension element 7 comprises two side walls 72 extending substantially in parallel with the side walls 52, 52' of the connector element 5, 5' when the extension element 7 is mounted on the connector element 5, 5', and the side walls 72 form a gutter 73 extending in continuation of the gutter 53, 53' of the connector element 5, 5' when so mounted.
  • the extension element 7 has a first end 713 adapted for engaging the second end 514, 514' of the connector element 5, 5' and a second end 714 adapted for facing away from the connector element 5, 5'.
  • the extension element 7 is practically identical to the connector element 5, 5' in the second end 514, 514' thereof in the sense that, in the respective second ends, the dimensions of the cross-section of the gutter 73 of the extension element 7 are identical to the dimensions of the cross-section of the connector element 5, 5', the extension element 7 is provided with first and second raised sections 731 and 734 similar to the raised sections 531 and 534 of the connector element 5, 5', said first and second raised sections 731 and 734 being mutually connected by a central wall 736 providing strength to the extension element 7 while allowing any water in the gutter 73 to drain off to the extreme end of the second end 714 of the extension element 7.
  • the first raised sections comprise openings 732 and small projections 733 corresponding respectively to the openings 532 and the small projections 533 and the second raised sections 734 comprise through holes 735 corresponding to the through holes 535.
  • attachment members 772 which preferably, but not necessarily, are positioned equidistantly on outer sides 721 of the side walls 72 of the extension element 7.
  • the attachment members 772 are identical to the attachment members 572.
  • weakenings and/or cutting guides 774 are provided between adjacent attachment members 772.
  • an adaptor element 6, 6' may be connected to the extension element 7 like to the connector element 5, 5', and the extension element 7 may be shortened in the same way as described with reference to the connector element 5, 5'.
  • the first end 713 of the extension member 7 is provided for connection with the connector element 5, 5' as follows.
  • the width of the gutter 73 of the extension element 7 is larger than the width of the connector element 5, 5' at its second end 514, 514', so that the first end 713 of the extension element 7 may embrace the second end 514, 514' of the connector element 5, 5' in the mounted state.
  • the side walls 72 and the bottom of the gutter 73 are offset at the first end 713 of the extension element 7 to provide for said first end 713 embracing the second end 514, 514' of the connector element 5, 5'.
  • the inner sides of the side walls 52, 52' and the inner sides of the side walls 72 are flush when the extension element 7 is mounted on the connector element 5, 5' and likewise are the bottoms of the respective gutters 53/53' and 73.
  • Each side wall 72 of the extension element 7 has at its first end 713 on an inner side facing the gutter 73 a corresponding attachment element 77, which in the mounted state, as shown in Figs. 6 , 12-15 and 22 is in engagement with the attachment element 57 on the adjacent side wall 52, 52' of the connector element 5, 5'.
  • the corresponding attachment element 77 of the extension element 7 is provided by a section of the side walls 72 at the first end 713 which has a recess 775 to provide a clear space for four attachment members 572, when the extension element 7 is in the mounted position shown in e.g. Figs. 14 and 15 , and around the recess 775 two openings 776 are provided which are adapted to receive respective attachment members 572, 572a.
  • the opening 776a closest to said offset will engage the attachment member 572a at the extreme end of the second end 514, 514' of the connector element 5, 5' and the other of the two openings 572 will engage with the 6th attachment member 572 counted from said extreme end. It should be understood that this count is due to the actual dimensions selected for the present embodiment which dimensions might well be changed for another embodiment.
  • the attachment member 572a at the extreme end of the second end 514, 514' of the connector element 5, 5' and the 6th attachment member 572 counted from said extreme end together provide an elongated attachment element.
  • said two attachment members might be substituted by a single elongate element with the same overall elongate extent as the said two attachment members provided the recess 775 was expanded correspondingly to merge with the two openings surrounding it in the embodiment shown.
  • the embracement may per se provide for overall rigidity of the connected elements provided an attachment element is positioned centrally relative to the overlap.
  • Such attachment element may be substantially punctual, i.e. not elongated.
  • the provision of an elongated attachment element will per se provided for, and will thus add to, the overall rigidity of the connected elements.
  • the sections or parts 777 of the side walls 72 of the extension element 7 adjacent the openings 776, opposite the bottom of the gutter 73 are slightly offset outwardly. This facilitates assembly of the extension element 7 and the connector element 5, 5', which are assembled similarly to the way the adaptor element 6, 6' is assembled with the connector element 5, 5', or with the extension element 7, whose parts relevant for assembly with the adaptor element are identical to the parts of the connector element relevant for assembly with the adaptor element, as explained above. Thus for assembly of the extension element 7 and the connector element 5, 5' the latter is lowered, interior side 512, 512' first, in between the side walls 72 of the extension element 7.
  • attachment members 572 Due to the attachment members 572 being shaped as obliquely truncated cones a wedging effect is obtained when the attachment members 572 abuts on the upper edge of the side walls 72 above the respective openings 776 and the connector element 5, 5' is pressed further towards the bottom of the extension element 7.
  • the side walls 72 of the extension element 7 and the side walls 52, 52' of the connector element 5, 5' are elastically deformed until the attachment members 572 snap into the respective openings 776, the flanges 622 and side walls 52, 52' returning to their original positions.
  • the attachment members 572 are dimensioned to suit assembly with the adaptor element 6 but for assembly with the extension element 7 the attachment might preferably be shallower to limit the forces involved in the assembly process.
  • An effect similar to the effect of providing shallower attachment members is obtained by the offset of said parts 777 of the side walls 72 of the extension element 7 adjacent the openings 776, opposite the bottom of the gutter 73 i.e. at the free edges of the side walls 72
  • Offsetting sections or parts 777 as mentioned, particularly adjacent to the free edges of the side walls 72, will help guide the connector element 5, 5' into the extension element 7 and/or prevent that the side walls 72 of the extension element are exposed to too high bending forces when being forced over the attachment members 572 on the connector element 5, 5'.
  • a wedging effect might be obtained by obliquely recessing or chamfering the inner sides of the above mentioned parts 777 of the side walls 72 of the extension element 7 adjacent the openings 776, opposite the bottom of the gutter 73, which the attachment members 572 will slide over and pass, when the connector element and the extension element are assembled.
  • the flashing members to be supported by one connector element 5, 5' e.g. the lower flashing members 41 may be provided with bent edges extending into the gutter 53 of said connector element 5, and an intermediate flashing member will be provided to cover the bent edges and the connector element.
  • one edge of a lower flashing element 41 e.g. the right edge as seen in Figs. 1 and 2
  • the straight edge may in such case receive fasteners 48, such as screws, see Fig. 1 , penetrating the straight edge, preferably through prefabricated openings surrounded by a raised bead, as it is known in the art, and into the raised projections 531 provided in the connector element 5 to receive such fasteners 48. It is noted that any such bent edges of the lower flashing elements, and correspondingly for the upper flashing elements, will lead any water that might penetrate between said flashing elements in to the gutter 53, 73, 61 provided the connector element 5, 5' and any present of the extension element 7 and the adaptor element 6.
  • a notch 49 in order to lock the position of the right bent edge 47 in the longitudinal direction a notch 49, see Fig. 5 , may be provided in said right bent edge 47 and a protrusion 58, see Fig. 22 , may be provided in the gutter 53 at the bottom and at the inner side of the left side wall, along which the right bent edge of the lower flashing member will extend, whereby the notch 49 may straddle the protrusion 58 to have its position locked in the longitudinal direction.
  • the protrusion 58 should not be so extensive that it would block the passage of water along the bottom of the gutter 53.
  • the second raised sections 534 and 734 found in the connector element 5, 5' and in the extension element 7, respectively, may be used to attach a reinforcement element (not shown) adapted for extending along the connector element and the extension element in the mounted state. It is noted that the second raised sections 534, 734 extends to a lower level from the bottom of the respective gutter 53, 73 than the first raised sections 531 and 731. Thus space will be left, below the flashing members, for a heads of screws to be inserted in the through holes 535, 735 to extend from the inner sides of the connector element and the extension element, pass through openings in the reinforcement element and receive nuts or the like (openings in the reinforcement element might be threaded holes) to fix the reinforcement element to the connector element and the extension element. Thus such screws would constitute further attachment members adapted for providing a connection to the reinforcement element.
  • the connector element 5, 5', possibly the extension element 7 and/or the adaptor element 6, 6' provides together an unbroken gutter extending from the connector element 5, 5' to the extreme end of the second end 714 of the extension element 7 and/or the end of the adaptor element 6 opposite the flanges 622 thereby leading any water that e.g. might penetrate between adjacent lower flashing elements 41 into the connector element 5 or between adjacent upper flashing elements 42 into the connector element 5' onto the roof 211 surrounding the upstand 2, 2'.
  • the different elements of the connector set i.e. the connector element 5, 5', the adaptor element 6, 6' and the extension element 7 are preferably made from plastic, such as acrylonitrile butadiene styrene (ABS), polyethylene (PE), polypropylene (PP) or polyvinylchloride (PVC), but other materials including metals and composites and combinations thereof may be employed as long as they are able to withstand the conditions on a roof. Different materials may be used for the three different elements.
  • plastic such as acrylonitrile butadiene styrene (ABS), polyethylene (PE), polypropylene (PP) or polyvinylchloride (PVC), but other materials including metals and composites and combinations thereof may be employed as long as they are able to withstand the conditions on a roof. Different materials may be used for the three different elements.
  • the configuration of the interior side of the different elements, especially of the connector element with its flanges, may be varied according to the actual installation situation the connector element should be provided for without influencing the configuration of the attachment elements for connecting the different elements.
  • the interior of the gutters may be varied and especially the position of any points of attachment for flashing members may be varied to correspond to actual flashing members to be supported by means of the connector element, etc.
  • the arrangement of the points of attachment, including the central wall, in the interior of the gutters may be used in connector elements and connector sets having different attachment elements or attachment means for mutual connection of the elements of the connector set.
  • a distinctive feature is the provision of the attachment elements on the outer side of the side walls of the connector element, whereby additional elements, such as the adaptor element and the extension element may be mounted or installed without any elements thereof extending into the interior of the gutter of the connector element to risk colliding with bent edges of flashing members extending in to said gutter.
  • the connector element 5, 5' is shown herein as used with roof windows mounted on a so-called upstand and adapted for riding on the window mounting brackets as described also e.g. in WO2015/02830 .
  • the connector element serves as a point of attachment for one or more flashing members and for draining off water, which has accumulated at the joint between two neighbouring windows. It is, however, to be understood that the connector element according to the present invention may also be used in other installation situations, where the flashing assembly and mounting brackets are of a different configuration.
  • attachment elements 57 and/or attachment members 572 are presented as protrusions protruding from the outer sides of the respective side walls 52, 52', 72 and the corresponding attachment elements 77 are described as depressions or openings 776, 776a; 623 in inner sides of respective side walls 72 or flanges 622, the opposite arrangement would also be possible according to the invention, i.e. the outer sides of the respective side walls 52, 52', 72 would comprise depressions or openings and the inner sides of respective side walls 72 or flanges 622 would comprise protruding protrusions.
