Definitions

  • the present invention relates to a connector for a telescopic drainage gutter of the type comprising an elongate external gutter profile and an elongate internal gutter profile, wherein the internal gutter profile and the external gutter profile are configured for sliding in relation to each other along a longitudinal direction and has a U-shaped cross-section in a transverse plane perpendicular to the longitudinal direction, each of the external and internal gutter profiles extends in the longitudinal direction in an assembled state, and each profile comprises a bottom for guiding away water along the longitudinal direction, a first U-leg, and a second U-leg, the first U-leg and the second U-leg extending from the bottom toward a top of each respective gutter profile and being spaced apart in a transverse direction, the transverse direction being perpendicular to the longitudinal direction, so that an interior space is present between the first U-leg and the second U-leg, and where the internal gutter profile is configured for sliding in the interior space of the external gutter profile along the longitudinal direction.
  • the present invention also relates to a kit comprising such connector and
  • a roof window often entails the mounting of a number of additional components, such as flashing and insulation components, which are typically supplied alongside the roof window.
  • One such component is a drainage gutter for guiding water away from an aperture in an underroof made to make room for the roof window in an inclined roof.
  • the drainage gutter is mounted along the top of the roof window and used to drain off water along the top of the roof window away from the aperture onto an intact part of the underroof extending along the side(s) of the roof window.
  • Telescopic type drainage gutters comprise at least two gutter profiles, one of which has a smaller cross-section so that it can slide lengthwise into the other having a larger cross-section.
  • One of the gutter profiles may be denoted as the external gutter profile and the other the internal gutter profile, referring to their respective positions when assembled. Prior to installation, the internal gutter profile can be fully inserted in the external gutter profile, allowing the telescopic drainage gutter to be packed with other roof window related components, rather than needing its own longer packaging.
  • the relative position of the two gutter profiles can be adjusted to provide a drainage gutter with a desired length, which allows the same drainage gutter to be used for different size windows and installation scenarios.
  • the telescopic drainage gutter is installed with an inclination relative to horizontal and with the internal gutter profile being positioned upstream of the external gutter profile creating a downwards overlap. This ensures that water flows down off a shoulder formed at the overlap between internal gutter profile and external gutter profile, and not in between the gutter profiles as might happen if the external gutter profile was positioned upstream so that the overlap was an upwards overlap.
  • the adjustable length of the telescopic drainage gutter allows a manufacturer to make one drainage gutter product, which can be used for a range of roof window sizes, the length being adjustable according to the width of the roof window in question.
  • the telescopic drainage gutter also provides the flexibility to adjust the drainage gutter length to the specific installation scenario to reach the intact part of the underroof. The length required may for example depend on rafter spacing. This solution has worked well, but when installing multiple roof windows side-by-side, such as 3, 4 or 5 roof windows side-by-side, the length of one telescopic drainage gutter may not be sufficient to provide drainage for all the roof windows.
  • each roof window is typically supplied with one telescopic drain gutter, hence when installing multiple windows side-by-side multiple pairs telescopic drainage gutter drains are available.
  • Multiple pairs of telescopic drainage gutter drains cannot simply be assembled, as water draining in a downstream direction would then encounter an external-to-internal gutter profile upwards overlap, where water could enter in between the gutter profiles and into the roof structure.
  • EP3231956A1 discloses another roof window drainage gutter, where each gutter profile has identical cross-sectional dimensions and where the gutter profiles are thin-walled and pliable, allowing them to be connected by deforming the gutter profiles to fit over/into each other. Having identical profiles to be connected by deformation requires a particular geometry, which limits the options in the design of the drainage gutter. In addition, deforming gutter profiles while on a roof may be troublesome for the installer. Having all gutter profiles be identical also increases the risk of the installer fitting them together incorrectly and creating an upwards overlap where water can enter between two gutter profiles.
  • US 1 682 840 A discloses a connector for telescopic gutter profiles.
  • the invention is defined by a connector according to claim 15.
  • the connector By providing the connector with the first connector section at one end and the second connector section at the other end, the connector will in the assembled state provide a bridge from an external gutter profile arranged upstream to an internal gutter profile arranged downstream.
  • the gutter profiles thus do not have to overlap and the risk of water entering in between the gutter profiles is eliminated.
  • two identical telescopic drainage gutters each having an internal gutter profile and an external gutter profile, can be connected each with their internal gutter profile arranged upstream, with the external gutter profile of the upstream telescopic drainage gutter having a downwards overlap with the connector and with the connector having a downwards overlap with the internal gutter profile of the downstream telescopic drainage gutter.
  • telescopic drainage gutter Water draining along such a sequence will only drop off the shoulders formed at the two internal-to-external connections, at the external-to-connector connection and at the connector-to-internal connection.
  • providing the connector alongside the telescopic drainage gutter as a kit allows the telescopic drainage gutter to be used with another further telescopic drainage gutter for large roof window installations, comprising for example 3 or more roof windows arranged side by side.
  • the further telescopic drainage gutter is in the context of the invention identical to the telescopic drainage gutter which is part of the kit according to the invention.
  • the connector of the kit is configured for connecting the internal gutter profile and the external gutter profile of telescopic drainage gutters
  • the connector can be used to connect the telescopic drainage gutter provided as part of the kit to the further identical telescopic drainage gutter, which is the main use contemplated.
  • the first U-shaped cross-section of the first connector section is larger than the second U-shaped cross-section of the second connector section.
  • an open area of first connector section is larger than an open area of the second connector section, the open areas being the cross-sections of the interior space of the connector in the transverse planes through the first and second connector section.
  • Providing the connector with connector sections which are sized to only fit one of the two gutter profiles also guides the installer to correct assembly, as the connector cannot be connected to gutter profiles in a manner providing an incorrect overlap, as could happen if both connector sections fit either gutter profile.
  • comparing the relative sizes of the first and second connector sections, or the U-shaped cross-sections thereof is done by evaluating corresponding dimensions.
  • transverse distances between the first and second side leg which may also be called a width, should be measured at the same distance from the bottom of the connector, i.e. at the same height position.
  • connection established when the internal gutter profile is positioned in the interior space of the external gutter profile is referred to herein as a telescopic connection or being telescopically connected.
  • a telescopic connection entails an overlap between the gutter profiles so connected.
  • the internal and external gutter profiles are configured to allow telescopic engagement along substantially their entire lengths, i.e. the internal gutter profile can be slid substantially fully into the external gutter profile.
  • the external and internal gutter profiles have substantially constant cross-sections along the longitudinal direction.
  • the first U-leg, second U-leg and bottom of the respective gutter profiles will generally have the same length and longitudinal ends of the gutter profiles will generally be perpendicular to the longitudinal plane.
  • the end sections of the gutter profiles overlap with the connector sections of the connector in the assembled state.
  • the surfaces of the connector sections, which are in contact with the gutter profiles in the assembled state, are referred to as engagement surfaces.
  • the internal gutter profile and external gutter profile which are connected to the connector, do not need to have been supplied together.
  • the internal gutter profile or external gutter profile of a telescopic drainage gutter supplied as part of the drainage gutter kit can be connected to one end of the connector, while a further internal gutter profile or further external gutter profile of a further identical telescopic drainage gutter can be connected to the other end of the connector.
  • the term "assembled state" in the context of the invention refers to the state in which an external gutter profile is connected to the first connector section of the connector and an internal gutter profile is connected to the second connector section, but does not require that the two gutter profiles so connected belong to the same kit.
  • a telescopic drainage gutter and a connector can be delivered with a roof window or with a flashing assembly for a roof window so that the connector is available in case the installation scenario requires it.
  • the connector can be made in mirror inverted versions designed for draining water the left or right of a roof window installation.
  • the kit may thus comprise two connectors, one for draining left and one for draining right.
  • the connector is made from a material, which can easily be recycled, such as plastic, and that the connector is relatively small compared to the drainage gutter to reduce material use.
  • the drainage gutter kit is described herein with reference to the longitudinal direction, the transverse direction and the terms top and bottom.
  • the longitudinal direction is the direction along which the drainage gutter kit extends in the assembled state and is also the direction along which water drains. When the assembled drainage gutter is installed on a roof, the longitudinal direction will be inclined in relation to horizontal.
  • the term bottom is used to refer to the closed portion of U-shaped cross-section and the term top refers to the open portion opposite to the bottom.
  • a height direction extends from the bottom to the top, and the height direction is perpendicular to both the longitudinal direction and the transverse direction. Distances in the longitudinal direction are referred to as lengths, distances in the transverse directions are referred to as widths, and distances in the height direction are referred to as heights.
  • U-shaped refers to a shape with is closed at one end, i.e. at the bottom, and open at the top, with sides extending between top and bottom.
  • the shape can also be referred to as "gutter-shaped".
  • U-leg is used to refer to a side of a gutter profile, whereas the term side leg is used for a side of the connector.
  • the legs of the U-shape may have similar heights, or one leg may be taller than the other.
  • the sides may be parallel as seen in the transverse plane in which case the transverse distance between the sides will be the width of the bottom.
  • the sides may alternatively extend at an angle to each other, whereby the bottom may be the intersection of the sides or alternatively be a leg extending between the sides when the sides do not intersect.
  • the first U-legs of the gutter profiles are the U-legs, which abut the roof structure in the mounted state. In the assembled state, the first U-leg of an internal gutter profile and the first U-leg of an external gutter profile extend in continuation of the first side leg of the connector.
  • the second U-leg of an internal gutter profile and the second U-leg of an external gutter profile extends in continuation of the second side leg of the connector.
  • the first U-legs of the gutter profiles and the first side leg of the connector may be taller than the second U-legs and the second side leg, respectively.
  • the interior dimensions of the first connector section correspond to exterior dimensions of the end section of the external gutter profile, which end section is received in the first connector section in the assembled state
  • exterior dimensions of the second connector section correspond to interior dimensions of the end section of the internal gutter profile, which end section is received in the second connector section in the assembled state.
  • exterior dimensions refer to distances extending along exterior surfaces of the gutter profile or connector and to distances between such exterior surfaces.
  • an interior width between the first side leg and second side leg at the first connector section corresponding to the exterior width between exterior surfaces of the first U-leg and second U-leg of the external gutter profile allows the external gutter profile to be retained in the first connector section.
  • the exterior width between exterior surfaces of the first side leg and second side leg at the second connector section corresponding to the interior width between the first U-leg and second U-leg of the internal gutter profile will retain the internal gutter profile to the exterior of the second connector section.
  • a transverse distance D1 between the first side leg and second side leg of the connector at the first connector section is greater than a corresponding transverse distance D2 between the first side leg and second side leg of the connector at the second connector section, both in the assembled state in a non-assembled state of the drainage kit.
  • the transverse distance D1 may also be referred to as the interior width of the first connector section, and the transverse distance D2 may be referred to as the interior width of the second connector section.
  • the non-assembled state refers to a state where the connector is not connected to any gutter profile.
  • the shape and size of the connector guides the installer to correctly assembling the connector and with the gutter profiles, by the ends of the connector matching the gutter profile with which should be connected.
  • the distances D1 and D2 are evaluated at the same height position.
  • the connector comprises a bridge section between the first connector section and the second connector section.
  • the bridge section extends in the longitudinal direction between the first connector section and the second connector section, and a portion of the first side leg and/or a portion of the second side leg extending in the bridge section extends at a bridge angle with respect to the longitudinal direction.
  • the bridge section provides a narrowing of the interior space of the connector in the direction from the first end to the second end of the connector, i.e. from interior width D1 to interior width D2.
  • This bridge section may also provide a block for the gutter profiles when the installer slides the gutter profiles onto/into the connector.
  • the portions of the first side leg and second side leg extending in the bridge section may be referred to as the first bridge side and the second bridge side.
  • One or both bridge sides can extend at a bridge angle with respect to the longitudinal direction.
  • the two bridge sides may extend at different bridge angles.
  • Preferably only one bridge side extends at a bridge angle with respect to the longitudinal direction, while the other is parallel with the longitudinal direction.
  • the one angled bridge side may preferably be the second bridge side. In this way the exterior surface of the first side leg, which is the side leg facing the roof structure when in use, can be plane, which may be advantageous when mounting the assembled drainage gutter to the roof structure.
  • the length of the bridge section is preferably short in relation to the lengths of first and second connector sections.
  • the length of the bridge section may be less than 75 % of the length of each of the connector sections, or less than 50 %, less than 25 % and even less than 10 %.
  • the bridge angle can refer to an angle formed by an interior surface and/or exterior surface of the portions in the bridge section, which means that the thickness of the bridge side may not be constant.
  • the first bridge side and/or second bridge side is/are substantially perpendicular to the longitudinal direction of the connector, meaning that the bridge angle is approximately 90°.
  • the bridge section can be made short in the longitudinal direction, reducing the size of the connector.
  • a bridge angle of 80° to 90° is, however, also contemplated.
  • a bridge angle of approximately 90° also potentially provides for a better stop for the gutter profiles during assembly, whereby the installer is less likely to force the gutter profiles too far into/onto the connector.
  • the length of the bridge section may be substantially the width of the material forming the connector side legs, which can be less than 5 mm.
  • only one of the portions of the first or second side leg, preferably the portion of the first side leg, extending in the bridge section has the substantially perpendicular bridge angle, while the portion of the second side leg extending in the bridge section is parallel to the longitudinal direction.
  • a top portion of the first U-leg and a top portion of the second U-leg of the external gutter profile forms a first profile track and a second profile track, respectively
  • a top portion of the first U-leg and a top portion of the second U-leg of the internal gutter profile forms a first guide member and a second guide member, respectively
  • the first and second profile tracks of the external gutter profile being configured for receiving the first guide member and second guide member of the internal gutter, respectively.
  • the gutter profile tracks may for example have a surface facing toward the bottom of the external gutter profile, against which surface the top portions of the internal gutter profile can abut, thereby prevent the internal gutter profile from rotating about the transverse direction.
  • the gutter profile tracks are channels shaped and sized to receive the top portion or guide member of the internal gutter profile.
  • the gutter profile tracks have an open configuration where they are open at one side, through which open side the U-legs of the internal gutter profile can extend into the gutter profile track.
  • the gutter profiles will typically be made from a sheet material, e.g. sheet metal, which has been bent to have the U-shaped cross-section.
  • the gutter profile tracks can be made by bending the top portion of the U-legs to form a longitudinally extending groove. This configuration is sometimes referred to as an open hem.
  • the term guide member refers to the part of the U-legs of the internal gutter profile which is received in the corresponding profile tracks of the external gutter profile.
  • the gutter guide members can be provided in a particular shape fitting into the gutter profile track.
  • the gutter guide member may for example be a flange extending at an angle to the remaining part of the U-legs, or part of the U-leg can be bend on to itself, providing a closed hem, or combinations thereof.
  • the gutter guide member may have a shape similar to the gutter profile track, but of smaller size. Guide members having such flanges or closed hems can provide surfaces which can rest and/or abut against corresponding surfaces of the gutter profile tracks, when the gutter profiles are telescopically connected. While the gutter profile tracks and guide members are mainly provided to improve the telescopic connection between the gutter profiles, the connector can also be configured to make use of the gutter profile tracks and guide members when the gutter profiles are connected to the connector.
  • the first and second profile tracks are open toward the bottom of the external gutter profile. Such profile tracks can be provided by the top portions of the U-legs being bent or folded toward the interior space of the external gutter profile.

  • a top portion of the first side leg and/or second side leg of the connector forms one or more tracks for receiving corresponding top portions of the first U-leg or second U-legs of the internal gutter profile and/or the external gutter profile.
  • Such tracks can, as the gutter profile tracks of the gutter profile, both guide the assembly of the connector and gutter profile and engage the gutter profile to retain it in the pertinent connector section.
  • the tracks can be provided at the first side leg, at the second side leg or at both. Tracks can be provided in both the first connector section and the second connector section.
  • the tracks in a connector section will typically extend from one end of the connector to the bridge section.
  • the tracks are shaped and sized to receive the top portions of the U-legs of the gutter profiles.
  • the tracks can be shaped and sized to receive gutter profile top portions in the from profile tracks and guide members.
  • the tracks of the connector Similar to the gutter profile tracks of the external gutter profile, the tracks of the connector have an open configuration where they are open at one side, whereby the U-legs of the internal gutter profile or external gutter profile can extend into the tracks of the connector.
  • the top portion of the first side leg and/or the top portion of the second side leg is/are folded toward the interior space of the connector providing a first side track and/or a second side track, which first and second side tracks are configured for receiving a top portion of the first U-leg of the external gutter profile and a top portion of the second U-leg of the external gutter profile, respectively.
  • the first connector section is configured to receive the external gutter profile in the interior space of the connector, the first and second side tracks will wrap around the top portions of the external gutter profile.

  • the top portion of the first side leg and/or the top portion of the second side leg is/are folded away from the interior of the connector providing one or two exterior tracks, the exterior track(s) being configured for receiving the top portion of the first U-leg or second U-leg of the internal gutter profile.
  • the exterior tracks will wrap around the top portions of the external gutter profile. If the top portions of the internal gutter profile are formed as guide members, the exterior tracks are shaped and sized to receive the gutter guide members of the internal gutter profile.
  • a top portion of the connector or of a gutter profile being folded is not to be construed as being limited to the portion having shaped by bending and folding the material of the top portion; the portion could also be formed in a folded shape, e.g. by moulding.
  • the top portion of the first and/or second side leg at the second connector section is configured to engage the gutter guide member from below, supporting the gutter guide member.
  • one side leg at the second connector section forms an exterior track and the other side leg engages the gutter guide member of the internal gutter profile, which guide member extends into the interior space of the internal gutter profile.
  • one or more of the tracks of the connector such as the first side track, second side track and/or exterior track(s), comprises a protrusion protruding into an interior space of the at least one track.
  • the at least one track may comprise more than one such protrusion.

  • a part of the bottom will extend further in the longitudinal direction than other parts of the bottom. In this way, when connecting the gutter profile to the connector, contact is increased gradually as the gutter profile and connector come into engagement. This may facilitate assembly for the user.
  • the entire end edge of the bottom can be angled with respect to the transverse direction, or the end edge can be composed of one or more angled portions and one or more portions, which are parallel with the transverse direction.
  • the bottom angle may be 2 to 45°, such as 2 to 30° or 2 to 20°. Having a bottom angle also offsets an end edge of the first side leg from and end edge of the second side leg in the longitudinal direction. This may allow one side leg to engage the gutter profile before the other side leg when the user connects a gutter profile to the connector, thereby guiding the gutter profile to the correct position during assembly.
  • the first side leg extends further than the second side leg in the longitudinal direction.
  • an end edge of the first side leg or second side leg, or a portion said end edge is inclined in relation to the longitudinal direction. This will also provide staggered engagement.
  • an end edge of the first side leg and/or of the second side leg comprises a non-linear section, such as curved or angular section.
  • Providing the non-linear section is another way of providing staggered engagement between the gutter profile and the connector.
  • the non-linear section can include a bulge or recess in the longitudinal direction.
  • a top portion of the first side leg and/or of the second side leg comprises a bevelling at the first end or second end of the connector.
  • the bevelling extends from an end edge of the first side leg or of the second side leg to a longitudinal edge of the first side leg or second side leg, respectively.
  • the bevelling may be provided on a leg or a portion forming a track of the connector, e.g. the first side track, second side track or an exterior track.
  • One or more of the top portions may have such a bevelling.
  • the bevelling may be linear bevelling or a curved bevelling. Providing a bevelling may provide staggered engagement of a gutter profile to the top portion, as contact may increase gradually along the bevelling. Bevellings can for example allow the gutter profile to engage one side of a track of the connector first, which will guide the gutter profile into the track and then gradually engage another opposite side of the track.
  • staggered engagement is achieved by the connector having combinations of bevellings, non-linear sections, bottom angles, inclined end edges of the side legs, and/or longitudinally offset side legs.
  • first connector section and/or second connector section each comprise three staggered contact points, each of the contact points having different positions in the longitudinal direction.
  • a first of the contact points is at the bottom of the connector
  • a second of the contact points is at the top portion the first side leg
  • a third of the contact points is at the top portion of second side leg, whereby the gutter profile will engage the three staggered contact points sequentially when being brought into engagement with the connector.
  • Arranging three staggered contact points, one at the bottom and one at the top portion of each of the two side legs may facilitate the assembly process as the contact established at the first contact point may guide the gutter profile in relation to the connector section, while the contact established at the subsequently engaged contact points constrains the gutter profile in relation to the connector section.
  • the concept of contact points is to be understood as follows.
  • the connector sections of the connector have a number of engagement surfaces which engage the gutter profiles in the assembled state.
  • the bottom of the connector has an engagement surface at the first connector, which is surface facing the interior space of the connector.
  • the engagement surface of the bottom is the one facing away from the interior space of the connector, as that surface will engage the interior of the internal gutter profile.
  • the first side leg, second side leg, and any tracks thereof may have engagement surfaces.
  • Such an engagement surface has a leading edge, which leading edge is the edge of the engagement surface which faces away from the centre of the connector as seen in the longitudinal direction. Hence, when a profile is connected to the connector it comes into contact with the engagement surface at the leading edge.
  • the contact points are positioned at these leading edges.
  • the leading edge is has one contact point. If the leading edge is engaged gradually, e.g. if the leading edge is angled, the leading edge is said to have two contact points, one of the two contact points being the point at which the leading edge initially engages the profile and the other contact point being the point at which the gutter profile fully engages the leading edge.
  • the contact point which provides initial contact will position the gutter profile, and the contact point which provides full engagement to the leading edge will further secure the position of the gutter profile. Intermediate points along the leading edge are thus not considered as contact points in this context.
  • the leading edges will be the end edges of the bottom, first and second side legs including bevellings provided thereon, as these edges face in the longitudinal direction.
  • an interior surface of the bottom of the connector at the first connector section is an engagement surface and the end edge of the bottom at the first end of the connector is the leading edge of that engagement surface.

  • This leading also has two contact points, an initial contact point and furthest from the bridge section of the connector, and a contact point of full engagement at the opposite end of the leading edge.
  • the staggered contact points can be provided by having the bottom, first side leg or second side leg, or edges thereof, extend to different longitudinal positions. Having the end edge of the bottom extend at the bottom angle with respect to the transverse direction, offsetting the side legs longitudinally, providing non-linear sections or inclined portions of the end edges of the side legs, and/or providing bevellings, can also be used to provide staggered contact points.
  • the first contact point is at a junction of the bottom and first side leg
  • the second contact point is at a bevelling of the top portion of the first side leg
  • the third contact point is at a bevelling of the top portion of the second side leg
  • a first, second and third longitudinal distance extend from the second end of the connector to the first, second and third contact points, respectively, and the first distance is greater than the second distance and the second distance is greater than the third distance.

  • the first contact point is at the junction of the bottom and the first side leg
  • the second contact point is at the top portion of the first side leg
  • the third contact point is at a bevelling of the top portion of the second side leg, where a first, second and third longitudinal distance extend from first end of the connector to the first, second and third contact points, respectively, and the first distance is greater than the second distance and the second distance is greater than the third distance.

  • the first side leg and/or the second side leg comprises a snap-lock for engaging with an aperture or projection in/on one of the U-legs of the internal gutter profile and/or external gutter profile.
  • Providing snap-lock helps retain the gutter profiles and the connector in the assembled state, but may also provide an auditory or tactile signal for the user indicating correct positioning of the gutter profile in/on the connector.
  • An aperture in the gutter profile may be one of a plurality of apertures intended to be used as a pre-formed hole through which fasteners can be inserted when installing the drainage gutter to the roof structure in a traditional way, i.e. without connecting it to a connector.
  • a length of the first connector section and a length of the second connector section of the connector are each at least 40 mm.

In this way the overlap between the connector and gutter profiles at both ends is at least 40 mm, which provides secure fixation of the connector to the gutter profiles.
  • the lengths of the connector sections may be measured at the bottom of connector. The lengths can be measured from the bridge section to the first end or second end of the connector, respectively.
