Description

Technical Field

[0001] The utility model relates to a groove profile for a telescopic drainage groove, which is used to guide water away from an opening in an underroof. The groove profile is an elongated groove profile extending in a longitudinal direction, and comprises a first longitudinal end, a second longitudinal end, a bottom extending in the longitudinal direction for guiding water away, a first leg and a second leg, wherein the first leg and the second leg extend in the longitudinal direction and are spaced apart in a transverse direction, thereby providing an internal space between the first leg and the second leg, and the transverse direction is perpendicular to the longitudinal direction, wherein the second leg of the groove profile comprises an inwardly protruding portion extending into the internal space at the top of the second leg, and the top is opposite to the bottom of the groove profile in a height direction perpendicular to the longitudinal direction and the transverse direction. Background Art

[0002] The installation of a roof window generally requires the placement of a number of additional components, such as flashing components and insulation components, which are usually supplied with the roof window. One such component is a gutter that is used to direct water away from an opening in the lower roofing that is made in the pitched roof to form a space for the roof window. The gutter is placed along the top of the roof window and is used to drain water along the top of the roof window in the direction of the pitch of the telescopic gutter and onto an intact portion of the lower roofing that extends along the side of the roof window.

[0003] Various gutter designs are known, one of which is a telescopic type gutter disclosed in EP1131513B1. The telescopic type gutter comprises at least two gutter profiles, one of which has a smaller cross section so that the gutter profile can slide longitudinally into another gutter profile having a larger cross section. With reference to the respective positions of the gutter profiles when assembled, one of the gutter profiles can be referred to as an outer gutter profile and the other gutter profile can be referred to as an inner gutter profile. Prior to installation, the inner gutter profile can be fully inserted into the outer gutter profile, thereby allowing the telescopic gutter to be packaged with other roof window related components without requiring its own longer packaging. During installation, the relative positions of the two gutter profiles can be adjusted to provide a gutter having a desired length. This further allows the same gutter to be used for windows of different sizes and different installation situations. In use, the telescopic drain gutter is installed with a certain inclination relative to the horizontal plane, and wherein the inner groove profile is positioned upstream of the outer groove profile, thereby creating a downward overlap. This ensures that water flows downward from the longitudinal end of the inner groove profile and flows onto the outer groove profile, and the risk of water entering between the groove profiles is very low, which may occur in the case where the outer groove profile is positioned upstream of the inner groove profile - which will provide an upward overlap in the direction of water flow, where water can flow between the groove profiles.

[0004] Telescopic guttering with adjustable length allows manufacturers to manufacture a guttering product that can be used for a range of roof window sizes, with the length in question being able to be adjusted according to the width of the roof window. Telescopic guttering also provides the flexibility to adjust the gutter length to reach the intact part of the lower roof according to the specific installation scenario. For example, the required length may depend on the rafter spacing. This solution works well, but when multiple roof windows are installed side by side, such as 3, 4 or 5 roof windows are installed side by side, the length of a telescopic gutter may not be enough to provide drainage for all roof windows. In these cases, multiple guttering can be individually placed and tilted so that the multiple guttering drains are drained to the left and right sides of the roof window mounting portion, respectively, resulting in complicated installation and increased risk of installation errors. It is economically undesirable to manufacture special guttering that is only used for specific installation scenarios.

[0005] At present, each roof window is usually equipped with one telescopic gutter, which is usually located in a package of additional components separate from the roof window. Therefore, when multiple roof windows are installed side by side, multiple telescopic guttering is available. However, multiple telescopic guttering cannot be simply assembled in a telescopic manner, because water discharged in the downstream direction will encounter an outer to inner gutter profile connection with an upward overlap, where water may enter between the gutter profiles and into the roof structure.

[0006] EP3231956A1 discloses another roof window drainage gutter system, wherein each gutter profile has the same cross-sectional dimensions, and wherein the gutter profile is thin-walled and flexible, thereby allowing the gutter profiles to be connected by deforming the gutter profiles to fit over and / or into each other. Connecting identical profiles by deformation requires specific geometries, which limits the choice of design for the drainage gutter and may result in expensive gutter profiles. In addition, deforming the gutter profiles when on the roof may cause difficulties for the installer. Making all the gutter profiles identical also increases the risk that the installer will mistakenly fit the gutter profiles together and create an upward overlap between two gutter profiles where water can enter.

[0007] It would therefore be desirable to provide an improved or alternative telescoping gutter assembly that is easy for the installer to use and that can provide cost-effective and space-efficient drainage for a wide range of roof window installations. Utility Model Content

[0008] These and further objects are achieved by a first aspect of the present invention, which provides a groove profile according to the introduction, wherein the second leg of the groove profile comprises a first end section located at a first longitudinal end and a main section adjacent to the first end section, the first end section and the main section being arranged sequentially in the longitudinal direction, and wherein the height of the first end section in the height direction is less than the height of the adjacent main section in the height direction.

[0009] Providing the first end section with a reduced height compared to the main section allows the first longitudinal end of the groove profile to be positioned in the inner space of another groove profile of another telescopic drainage groove, thereby providing a desired downward overlap in the direction of water flow, and at the same time allowing the groove profile to slide longitudinally with the other profile of the other telescopic drainage groove. In this way, the groove profile according to the utility model can be used as one of the two groove profiles of a telescopic drainage groove in a typical telescopic manner (the manner in which the inner groove profile slides in the outer groove profile), but can also be connected to the other telescopic drainage groove by the desired downward overlap. Therefore, the groove profile according to the utility model is universal, and the way in which the groove profile according to the utility model is used depends on the needs of a specific roof window installation. In addition, the groove profile according to the utility model can be produced by modifying an existing telescopic drainage groove profile, whereby the same production line can be used. For example, the first end section may be a portion of the second leg, wherein part of the second leg at the first longitudinal end has been removed or has been folded downwards towards the bottom of the channel profile, thereby reducing the height of the second leg in said portion.

[0010] The groove profile according to the utility model can be considered to include multiple parts: at least a first end portion and a main portion. The first end portion of the groove profile is a longitudinal portion of the groove profile in which the first end section of the second leg extends. The main portion of the groove profile is a longitudinal portion in which the adjacent main section of the second leg of the groove profile extends. The main portion extends in the longitudinal continuation of the first end portion, and the first end portion extends from the first longitudinal end of the groove profile. Therefore, the first end portion includes the first end section of the second leg, and the longitudinal portion of the first leg corresponding to t and the bottom of the groove profile. Similarly, the main portion of the groove profile includes the main section of the second leg, and the longitudinal portion of the first leg corresponding to the main section of the second leg and the bottom of the groove profile.

[0011] The groove profile according to the utility model can be configured as an inner groove profile or an outer groove profile of a telescopic drainage groove, which has the function of being able to be connected to another telescopic drainage groove. This can be illustrated by the following example: in this example, a telescopic drainage groove having an inner groove profile and an outer groove profile, and an additional telescopic drainage groove having an additional inner groove profile and an additional outer groove profile are provided. The outer groove profile and the additional outer groove profile are identical, and the inner groove profile and the additional inner groove profile are identical, but at the first longitudinal end of the additional inner groove profile, the height of the second leg has been reduced, thereby providing a first end section of the second leg of the additional inner groove profile. The additional inner groove profile is therefore a groove profile according to the utility model. Therefore, the cross section of the inner groove profile in the plane (TH plane) defined by the transverse direction and the height direction is the same as the cross section in the main section of the first groove profile. Each of the telescopic gutter and the additional telescopic gutter can be used as an independent gutter, but the additional inner gutter profile can also be connected to the inner gutter profile by positioning the first end portion of the additional inner gutter profile including the first end section in the internal space of the inner gutter profile. This provides a gutter assembly, which includes an additional inner gutter profile, an inner gutter profile and an outer gutter profile in the direction of water flow, wherein each connection portion includes a downward overlap in the direction of water flow. In the case where a gutter assembly with three gutter profiles is sufficient for the roof window installation, the additional outer gutter profile can be discarded, preferably recycled. In the detailed description of the utility model, a gutter assembly that also uses an additional outer gutter profile, and other examples of gutter profiles and their uses according to the utility model are described.

[0012] It should be understood that one intended use of the groove profile according to the present invention is to connect it to another telescopic drainage groove that is already available for roof windows. Therefore, it should be understood that the size and cross-sectional shape of the groove profile according to the present invention are manufactured to correspond to one of the groove profiles of another telescopic drainage groove. In particular, the main part of the groove profile according to the present invention will have the same cross-section as one of the groove profiles of the other telescopic drainage groove in the TH plane. Therefore, the first end section of the second leg of the groove profile is configured to allow the groove profile to be connected to another groove profile, which has the same cross-section as the main part of the groove profile according to the present invention. In view of this, it should be understood that the features of the first end section or the first end part of the second leg are appropriately described relative to the main section or the main part of the second leg of the groove profile, because the main section and the main part correspond to another groove profile that can be connected to it.

[0013] Another intended use of the groove profile according to the present invention is to be connected to a second identical groove profile according to the present invention. As mentioned above, the first end section allows the groove profile to be connected to another groove profile having the same cross section as the main part of the groove profile, and correspondingly, the first end section also allows the groove profile to be connected to the main part of the second identical groove profile according to the present invention.

[0014] In the description of the present invention, unless otherwise specified, the groove profile to which the groove profile according to the present invention is configured to be connected is referred to as "another groove profile". The term "additional groove profile" is sometimes also used for economy of language and refers to the groove profile according to the present invention.

[0015] The groove profile according to the utility model is described with reference to the longitudinal direction, the height direction and the transverse direction perpendicular to each other. The groove profile has a groove-shaped cross-section, which provides a channel for draining water along the bottom of the groove profile. The longitudinal direction is the direction in which water flows along the bottom of the groove profile when the groove profile is in use. With regard to the channel of the groove profile, the transverse direction used herein is the direction in which the width of the channel extends, and the height direction is the direction in which the depth of the channel extends. The first longitudinal end and the second longitudinal end are the ends of the groove profile in the longitudinal direction, and these terms are not used to identify specific ends, such as the left end or the right end, but are used to distinguish one longitudinal end from another longitudinal end. The bottom of the groove profile extends in the longitudinal direction and is a part of the groove profile where water gathers and flows when the groove profile is in use. In some embodiments, the bottom of the groove profile is formed by the bottom leg of the groove profile, which extends in the transverse direction between the first leg and the second leg. In other embodiments, the bottom of the groove profile is formed by a first leg and a second leg directly connected to the groove profile, such as a V-shaped groove profile. The part referred to herein as the "top" part of the element, such as the top of the second leg, is the part opposite to the bottom of the groove profile in the height direction. Therefore, the top part is usually located at the free edge of the element.

[0016] The inwardly protruding portion of the second leg can be configured to slide in a corresponding inwardly protruding portion of another profile of the telescopic drainage groove. For example, when the groove profile is configured as an inner groove profile, the corresponding outer groove profile can have the following inwardly protruding portion: the inwardly protruding portion is configured to receive the inwardly protruding portion of the inner groove profile, thereby guiding and locking the telescopic connection of the two groove profiles in the height direction and / or the lateral direction. The first leg of the groove profile can also include an inwardly protruding portion extending from the top of the first leg into the inner space of the groove profile. The inwardly protruding portion can be provided by folding the top of the second leg or the first leg into the inner space of the groove profile. The inwardly protruding portion can, for example, be an open curling or a closed curling.

[0017] As used herein, height, width, length and distance are understood to be the projected (geometric) dimensions of the part in question in the relevant direction. Thus, the height of the first end segment of the second leg is the projected dimension of the first end segment in the height direction, and the height of the main segment of the second leg is the projected dimension of the main segment in the height direction.

[0018] The first end section of the second leg has a reduced height compared to the main section of the second leg, which allows it to be connected to another groove profile having substantially the same cross-section and dimensions as the main part of the groove profile. It can therefore be understood that the first end section is a portion of the second leg that has a reduced height compared to the main section.

[0019] In the first end section, the reduced height may be constant, i.e. uniform. It is also conceivable that the first end section has a non-uniform height, for example in an embodiment in which at least a portion of the top of the second leg slopes downwards towards the first leg. In an embodiment in which the first end section has a non-uniform height, the height of the first end section is the maximum height of the first end section.

[0020] A smaller recess or the like in the second leg which is not relevant in the context of the present invention is not considered in the context of the present invention as a first end section with reduced height, since such a smaller recess would not enable the intended connection to another channel profile.

[0021] The first end section of the second leg extends from the first longitudinal end of the groove profile to the adjacent main section of the groove profile. Accordingly, the first end portion of the groove profile in which the first end section extends also extends from the first longitudinal end of the groove profile to the main section.

[0022] In some embodiments, the inwardly projecting portion extends from the main section of the second leg of the groove profile. In this way, the main section provides a guiding and locking function as described above, wherein the inwardly projecting portion receives or is received by a corresponding inwardly projecting portion of another groove profile. The inwardly projecting portion may extend along the entire main section of the second leg in the longitudinal direction. The inwardly projecting portion extending from the main section of the second leg may be an open bead or a closed bead. The first end section may not have an inwardly projecting portion.

[0023] In some embodiments, the height of the first end section is substantially equal to the free distance in the height direction between the bottom of the groove profile and the downward facing surface of the inwardly protruding portion of the main section, which faces the bottom of the groove profile and is adjacent to the second leg. This can provide a more secure connection with another groove profile, because the first end section can abut the downwardly facing surface of the inwardly protruding portion of another groove profile, and thus be constrained in another groove profile, which has the same cross-section as the main part of the groove profile according to the utility model in the TH plane. The distance from the inner surface of the bottom is the free distance, which faces the internal space of the groove profile. The free distance is measured in the main section of the groove profile to the downwardly facing surface of the inwardly protruding portion, which is adjacent to the second leg of the groove profile, because the first end section or the second end section will be positioned adjacent to the second leg of the other groove profile when connected to the other groove profile and can therefore engage the downwardly facing surface of the other groove profile. The downwardly facing surface being adjacent to the second leg may be adjacent in the sense that the downwardly facing surface is located within 5, 4, 3 or 2 times the material thickness of the second leg from the second leg. When comparing the free distance to the height of the first end section, the height of the first end section is suitably measured from between the outer surfaces of the first end section, as said outer surfaces will be the surfaces that abut the other channel profile in the connected state.

[0024] In some embodiments, the distance between the outward facing surface of the first leg and the outward facing surface of the second leg, the lateral distance between the first leg and the second leg, and the thickness of the bottom extending in the height direction are constant along the entire length of the groove profile in the longitudinal direction, i.e. the material thickness is substantially the same over the entire length. This may be advantageous because it allows substantially the entire length of the inner groove profile to be accommodated in the outer groove profile. Furthermore, this may facilitate the production of the groove profile, since several groove profiles may be produced from one standard profile by cutting.

[0025] In some embodiments, the second leg of the groove profile includes a second end section located at the second longitudinal end, the second end section abuts the main section and is arranged sequentially with the main section in the longitudinal direction, and wherein the height of the second end section is less than the height of the adjacent main section. In this way, the groove profile can be connected to another groove profile at either longitudinal end, thereby allowing the groove profile to be used regardless of whether the direction of water flow is toward the first longitudinal end of the groove profile or toward the second longitudinal end. In such an embodiment, the groove profile is also referred to as having a second end portion, which is a longitudinal portion of the groove profile in which the second end section extends. The details and embodiments of the first end section described herein are also applicable to the second end section, so the height of the second end section can also be, for example, substantially equal to the free distance between the downward facing surface of the inwardly protruding portion and the bottom of the groove profile. Preferably, the first end section and the second end section are symmetrical. Preferably, the height of the second end section is equal to the height of the first end section.

[0026] At least a portion of the groove profile may be elastic, which allows the groove profile to deform. Since the size of the groove profile is in some respects the same as the size of another groove profile, the elasticity of the groove profile or the elasticity of the other groove profile allows the groove profile to deform when connected to another groove profile.

[0027] In some embodiments, the channel profile is made of sheet metal, preferably steel or aluminum. In the context of the present invention, such a channel profile is elastic.

[0028] In some embodiments, the length of the first end section and / or the second end section (if present) in the longitudinal direction is at least 5 cm, preferably in the range of 5 cm to 15 cm. More preferably, the length is 8 cm to 12 cm, and most preferably about 10 cm. These lengths can provide a sufficient length of overlap with another groove profile to reduce the risk of water entering between the groove profiles, and provide a secure connection between the groove profile and the other groove profile.

[0029] It should be understood that embodiments of the groove profile having both the first end section and the second end section can also be connected to another groove profile and the same second groove profile according to the utility model at the same time. For example, the groove profile can be an inner groove profile, which is connected to another inner groove profile by the first end section, which provides an overlap equal to the length of the first end section, which can be 10cm. Then, the same second inner groove profile according to the utility model can be connected to the inner groove profile by arranging the first end section of the same second inner groove profile in the main part of the inner groove profile at the second longitudinal end of the inner groove profile. Therefore, the same second inner groove profile will extend through the second end section of the inner groove profile and enter the main part of the inner groove profile, thereby providing an overlap equal to the sum of the length of the first end section of the same second inner groove profile and the length of the second section of the inner groove profile, which can be about 20cm. Therefore, it should be understood that a plurality of groove profiles according to the present invention can be connected in sequence, such as 2, 3, 4, 5 or more groove profiles connected in sequence. In order to use in this manner, it is preferred that the first end section and the second end section (if present) do not include a portion protruding therefrom, such as an inwardly protruding portion. Therefore, the first end section and the second end section are preferably planar. Advantageously, such an end section can be formed by removing a portion of the second leg.

[0030] The elasticity of the groove profile will generally allow the height of the first end segment and / or the second end segment to exceed the lateral distance between the first leg and the second leg to a certain extent and still allow rotation as described above because the leg of the other groove profile will temporarily yield during rotation. In some embodiments, the height of the first end segment and the height of the second end segment (if present) constitute 110% or less of the lateral distance between the first leg and the second leg. The height can be 109% or less of the lateral distance, 108% or less of the lateral distance, 107% or less, 106% or less, 105% or less, 104% or less, 103% or less, 102% or less, 101% or less, 100% or less, 95% or less, 90% or less. This facilitates connecting the groove profile to another groove profile because the groove profile allows the first end section or the second end section to be inserted into the interior space of the other groove profile in a manner that is angled with the first leg and the second leg of the other groove profile, and then the groove profile is rotated to connect it to the other groove profile. As mentioned above, this is particularly advantageous when the height of the first end section substantially corresponds to the free distance between the downwardly facing surface and the bottom of the inwardly protruding part of the main section, in which case the first end section can snap into place between the bottom and the inwardly protruding part of the other groove profile when rotated into place. This can be referred to as a "snap-lock" connection. It should be understood that the height of the second leg does not need to be 110% or less of all lateral distances between the first leg and the second leg to provide the above advantages. For example, the height of the first end segment may not be 110% or less of the lateral distance measured at the inward protrusion of the second leg, but still be 110% or less of the lateral distance measured elsewhere, such as below the inward protrusion, and thus still be able to rotate into position as previously described.

[0031] In some embodiments, the height of the main section of the second leg is less than the height of the first leg of the gutter profile. The height of the main section is also the total height of the second leg, and the second leg is preferably the shorter of the two legs. Therefore, the first leg is preferably the leg of the gutter profile that is configured to rest on the roof structure.

[0032] In some embodiments, the first leg is parallel to the second leg. In these embodiments, the bottom of the channel profile is formed by a bottom leg extending in a transverse direction between the first leg and the second leg.

[0033] In some embodiments, the groove profile further comprises a bottom leg extending between the first leg and the second leg and forming the bottom of the groove profile, wherein the bottom leg has a width in the transverse direction and the height of the first end section is less than the width of the bottom leg. In this way, the groove profile is easily connected to another groove profile by positioning the groove profile at an angle as described above and rotating the groove profile relative to the other groove profile.

[0034] In some embodiments, the first leg of the groove profile includes a first end section of the first leg at the first longitudinal end and a main section of the first leg of the groove profile, wherein the height of the first end section is less than the height of the main section of the first leg. The first end section of the first leg extends the same length as the first end section of the second leg. The first end section and the main section of the first leg are arranged sequentially in the longitudinal direction. Similarly, a second end section of the first leg having a reduced height compared to the main section of the first leg can be provided at the second longitudinal end.

[0035] In a preferred embodiment of the groove profile, the first leg of the groove profile is parallel to the second leg, and the bottom leg extends perpendicularly to the first leg and the second leg between the first leg and the second leg, wherein the height of the main section of the second leg is less than the height of the first leg. The length of the first end section is preferably at least 5 cm, and the second leg of the groove profile also includes a second end section located at the second longitudinal end, the length of the second end section also being at least 5 cm. More preferably, the height of the first end section and the second end section is substantially equal to the free distance between the bottom leg and the downwardly facing surface of the inwardly protruding part of the main section of the second leg. More preferably, the height of the first end section and the second end section is also 110% or less of the transverse distance between the first leg and the second leg of the groove profile, such as 105% or less, or 100% or less of the transverse distance.

[0036] In a second aspect of the present invention, a telescopic gutter for directing water away from an opening in a lower roof is provided, the telescopic gutter comprising an inner gutter profile and an outer gutter profile, the inner gutter profile being configured to slide in a longitudinal direction within an inner space of the outer gutter profile, wherein the inner gutter profile and / or the outer gutter profile are gutter profiles according to the first aspect of the present invention. The telescopic gutter according to the first aspect of the present invention can be used alone as a typical telescopic gutter, or connected to another gutter profile of another telescopic gutter. The telescopic gutter according to the present invention can advantageously be arranged as part of a component set for a roof window, the component set comprising a mounting or waterproofing assembly for a roof window installation, the component set being arranged for a roof window installation comprising a plurality of roof windows.

[0037] In a third aspect of the present invention, a system is provided, the system comprising a second telescopic gutter for directing water away from an opening in a lower roof and an additional gutter profile according to the first aspect of the present invention, the second telescopic gutter comprising an inner gutter profile and an outer gutter profile, wherein each of the inner gutter profile and the outer gutter profile is elongated and extends in a longitudinal direction, and comprises a gutter profile bottom extending in the longitudinal direction for directing water away, a gutter profile first leg and a gutter profile second leg, the gutter profile first leg and the gutter profile second leg being spaced apart in a transverse direction so that the gutter profile first leg and the gutter profile second leg are ... An internal space is provided between a leg and a second leg of the groove profile, and the second leg of the groove profile of each of the inner groove profile and the outer groove profile includes an inwardly protruding portion extending into the internal space at the top of the second leg of the groove profile, the top of the second leg of the groove profile being opposite to the bottom of the groove profile in the height direction, the inner groove profile is configured to slide in the longitudinal direction within the internal space of the outer groove profile, and wherein the additional groove profile is configured to slide in the longitudinal direction within the internal space of the outer groove profile, or wherein the additional groove profile is configured to allow the inner groove profile to slide in the internal space of the additional groove profile.

[0038] As described with respect to the groove profile according to the first aspect, the additional groove profile has a first end portion, a main portion and a second end portion that may exist. In the system according to the present invention, the additional groove profile configured to slide in the inner space of the outer groove profile along the longitudinal direction refers to the cross-section of the main portion of the additional groove profile being substantially equal to the cross-section of the inner groove profile of the telescopic drainage groove, which cross-section refers to the TH plane. Similarly, when the additional groove profile is configured to allow the inner groove profile to slide in the inner space of the additional groove profile, the cross-section of the main portion of the additional groove profile is substantially equal to the cross-section of the outer groove profile.

[0039] The additional groove profile of the system according to the invention may be provided as a part of the additional groove profile according to the second aspect of the invention.

[0040] The outer channel profile and the inner channel profile of the telescopic drainage channel of the system may be elastic, as previously described with respect to the first aspect of the present invention.

[0041] In a fourth aspect of the present invention, a method for assembling the system according to the third aspect of the present invention is provided, the method comprising the following steps:

[0042] (a) at least partially retracting the outer groove profile from the inner groove profile, and

[0043] (b) Attach additional gutter profiles to the telescopic gutter by any of the following means:

[0044] (b1) arranging a first longitudinal end of the additional groove profile in the inner space of the inner groove profile, in the case where the additional groove profile is configured to slide in the longitudinal direction within the inner space of the outer groove profile, or

[0045] (b2) In a case where the additional groove profile is configured to allow the inner groove profile to slide within the inner space of the additional groove profile, the first longitudinal end of the additional groove profile is arranged in the inner space of the outer groove profile.

[0046] This provides an assembled drain device having at least three connected gutter profiles. It is envisaged that step (b) may include both (b1) and (b2) in the case of a single additional gutter profile. Step (b) may additionally or alternatively include repeating steps (b1) or (b2) in the case of a single additional gutter profile.

[0047] In some embodiments, the method comprises providing a second additional groove profile according to the first aspect of the present invention, and connecting the second additional groove profile to the additional groove profile as in step (b1) or (b2). In this way, the assembled drainage gutter may include four or more groove profiles, for example, in the order of the water flow direction, the second additional inner groove profile is connected to the additional inner groove profile, the additional inner groove profile is connected to the inner groove profile, and the inner groove profile is connected to the outer groove profile.

[0048] In some embodiments of the method for assembling the system, step (b1) or (b2) comprises positioning the additional groove profile so that at least a portion of the first end section extends in the interior space of the inner groove profile at an angle to the second leg of the inner groove profile or in the interior space of the outer groove profile at an angle to the second leg of the outer groove profile, respectively, and rotating the additional groove profile about the longitudinal direction relative to the inner groove profile or relative to the outer groove profile. This provides a simple way of connecting the groove profiles, in particular when the height of the first end section is substantially equal to the free distance in the height direction between the bottom of the groove profile and the downwardly facing surface of the inwardly protruding part of the main section, because the rotation snaps the first end section between the inwardly protruding part and the bottom of the other groove profile and thereby snaps the additional groove profile into the groove profile.

[0049] In a fifth aspect of the present invention, there is provided a method for producing the groove profile according to the first aspect of the present invention, the method comprising the following steps:

[0050] - Provide blanks,

[0051] - forming the blank into an elongated channel profile extending in a longitudinal direction, the elongated channel profile comprising a first longitudinal end, a second longitudinal end, a bottom extending in the longitudinal direction for directing water away, a first leg and a second leg, the first leg and the second leg extending in the longitudinal direction and being spaced apart in a transverse direction, the transverse direction being perpendicular to the longitudinal direction, thereby providing an inner space between the first leg and the second leg,

[0052] - shaping the top of the second leg to provide an inwardly projecting portion extending from the second leg into the interior space, the top being opposite to the bottom of the channel profile in a height direction perpendicular to the longitudinal and transverse directions,

[0053] - reducing the height of a first end section of the second leg at the first longitudinal end.

[0054] The blank may be a sheet metal piece.Shaping the blank and forming the top portion of the second leg may each comprise folding the blank.

[0055] In some embodiments of the method for producing a channel profile, the step of reducing the height of the second leg comprises removing a portion of the second leg. For example, this may be cutting away a portion of the second leg to provide the first end section.

[0056] In some embodiments of the method for producing a groove profile, the step of reducing the height of the second leg comprises folding a portion of the second leg into the inner space of the groove profile. For example, this can be achieved by making a cut in the top portion of the second leg including the inwardly protruding portion, and folding the portion extending from the cut to the first longitudinal end of the groove profile towards the bottom of the groove profile.

[0057] The method for producing a groove profile may include further steps to provide further features of the groove profile of the above-mentioned embodiment. Thus, the method may, for example, include reducing the height of the second leg to provide a first end segment having a length of at least 5 cm or other lengths disclosed herein. Similarly, the height may be reduced in the method to provide a height of the first end segment that is substantially equal to the free distance in the height direction between the bottom of the groove profile and the downwardly facing surface of the inwardly protruding portion of the second leg, or to provide a height that is 110% or less of the lateral distance between the first leg and the second leg. As described with respect to the first aspect of the utility model, the method may also include a step for providing a second end segment of the second leg.

[0058] Further embodiments and advantages of the present invention will become apparent from the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] First refer to Figure 1 , Figure 1 Three roof windows 1 are shown installed side by side close to each other in a roof structure. A prior art telescopic gutter 2' is shown located above two roof windows, with an inner gutter profile 30' located on the left and an outer gutter profile 20' located on the right. The inner gutter profile 30' and the outer gutter profile 20' are configured to slide lengthwise relative to each other along a longitudinal direction L, thereby providing a telescopic connection. The direction of water flow in the telescopic gutter 2' is indicated by the arrow above the telescopic connection. With the inner gutter profile 30' located upstream, water will flow downward along the shoulder formed at the telescopic connection. It can be seen that the length of the telescopic gutter 2' is sufficient to span two of the roof windows 1, but not the third. Furthermore, the same telescopic gutter cannot simply be connected to the telescopic gutter 2', as this would provide an outer to inner profile connection in the direction of water flow, which would result in an upward overlap in the direction of water flow, where water could enter between the gutter profiles.

[0072] However, the elongated gutter profile 30 according to the present invention can be connected to the telescopic gutter 2', wherein a downward overlap is formed in the direction of water flow. Figure 1 In the embodiment, the groove profile 30 is configured as an inner groove profile 30, i.e., the groove profile 30 has the same dimensions as the inner groove profile 30' and slides lengthwise in the outer groove profile 20' except at the first longitudinal end 33 of the groove profile 30, where the height of the second leg of the groove profile is reduced (see Figure 3 ). The groove profile 30 may be connected to the inner groove profile 30' upstream of the inner groove profile 30', thereby providing a shoulder pointing downward in the direction of water flow. Figure 1 An embodiment of a system according to the present invention is shown in an unassembled state. For illustrative purposes, Figure 1 The groove profile 30 is configured so that the water flow direction is toward Figure 1 However, the height of the second leg of the groove profile 30 can also be reduced at the second longitudinal end 34 of the groove profile, which allows the groove profile 30 to be connected in the right side of the groove profile 30 with water in the telescopic drainage groove. Figure 1 Preferably, the height of the second leg is reduced both at the first longitudinal end 33 and at the second longitudinal end 34, thereby allowing the channel profile to be used in both cases. Figure 1 and below, in Figure 1 In the view of FIG. 3 , the first longitudinal end 33 is the right end, and the second longitudinal end 34 is the left longitudinal end, but it should be understood that the terms “first longitudinal end” and “second longitudinal end” are only used to distinguish one end from the other. Figure 1 The left longitudinal end in the view of FIG. Reference numerals followed by a prime (') are used herein for other groove profiles to which the groove profile according to the present invention can be connected, while reference numerals without a prime (') are used for the groove profile according to the present invention. The same reference numerals are used for the same or equivalent elements in the groove profile and other groove profiles.

[0073] Now go to Figure 2 and Figure 3 , which respectively show Figure 1 Detail of the second longitudinal end 34 and the first longitudinal end 33 of the channel profile 30 . Figure 2 and Figure 3 The groove profile is configured as an inner groove profile. The groove profile 30 extends from a first longitudinal end 33 to a second longitudinal end 34 in a longitudinal direction L. The groove profile 30 has a first leg 31 and a second leg 32 spaced apart in a transverse direction T and extending in a height direction H. The first leg 31 and the second leg 32 extend parallel to each other from the first longitudinal end 33 to the second longitudinal end 34 along the longitudinal direction L. The height of the first leg 31 is greater than the height of the second leg 32, wherein the second leg is about 1 / 3 of the height of the first leg 31. The first leg is configured to rest against a roof structure (not shown) and be fastened to the roof structure. In this embodiment, the bottom of the groove profile is formed by a bottom leg 35 extending vertically between the first leg 31 and the second leg 32, thereby providing a rectangular cross section of the groove profile 30 in a transverse height plane (TH plane). An internal space 300 is provided between the first leg 31 and the second leg 32, thereby forming a channel extending along the longitudinal direction L. Each of the first leg 31 and the second leg 32 is provided with an inwardly projecting portion 310, 320 at its respective top, and in this embodiment, the inwardly projecting portion is configured to be received by and slide lengthwise therein a corresponding inwardly projecting portion of an outer channel profile (not shown). Figure 2 At the second longitudinal end 34 shown, the inwardly projecting portion 320 of the second leg extends to the second longitudinal end 34, and the height of the second leg is not reduced at the second longitudinal end 34. However, at the first longitudinal end 33, a portion of the second leg 32 has been removed, thereby providing a section of the second leg having a reduced height compared to the remainder of the second leg 32. The section having a reduced height constitutes the first end section 323, and the remainder of the second leg constitutes the main section 325. In this embodiment, the first end section 323 has no inwardly projecting portion at the top. The dividing line between the first end section 323 and the main section 325 is represented by plane P1, where Figure 3, the portion of the groove profile 30 located to the right of the plane P1 is identified as the first end portion of the groove profile 30, and the portion located to the left of the plane P1 is identified as the main portion of the groove profile 30. In this embodiment, the main section 325 of the second leg and the main portion of the groove profile extend to the second longitudinal end 325. The first end section 323 has a free edge 3230 at the top of the first end section 323. The first end section 323 allows the groove profile 30 to be inserted into the inner space of another inner groove profile (not shown) whose cross section in the TH plane is the same as the cross section of the main portion of the groove profile 30 (therefore, the other groove profile (not shown) will look like Figure 2 groove profile shown).

[0074] Now go to Figure 4 , Figure 4 Another channel profile 30 according to the invention is shown as viewed from the second longitudinal end towards the first longitudinal end. Figure 4 The embodiment of the second leg 32 has a second end section 324 of a reduced height compared to the main section 325 of the second leg. The portion 321 of the inwardly protruding portion extending into the interior space 300 of the second leg 32 has been folded downwardly towards the bottom 35 to reduce the height of the second leg and thereby provide the second end section 324 of the second leg at the second longitudinal end. In the second end section 324, there is a free edge 3240 at the top of the second leg, and the height He1 of the second end section 324 extends between the free edge 3240 and the bottom 35 (measured to the outer surface of the bottom 35). The height Hm of the main section of the second leg extending between the bottom 35 and the inwardly protruding portion 320 of the main section is also shown, and it can be observed that this height Hm is greater than the height He1. In this embodiment, He1 is about 90% of Hm. Also shown is the lateral distance Dt between the first leg 31 and the second leg 32, and the free distance Dm between the inwardly facing surface of the inwardly protruding portion 320 of the main section of the second leg and the inner surface of the bottom 35. The free distance Dm is measured internally in the groove profile to the downwardly facing surface of the inwardly protruding surface 320, which is adjacent to the second leg 32. Figure 4 In the embodiment of , the downwardly facing surface adjacent to the second leg is the surface constituting the closed bead of the inwardly protruding portion 320. The height He1 is substantially equal to the free distance Dm, thereby allowing the second end segment 324 to be positioned and snapped into place between the bottom of the other groove profile corresponding to the main part of the groove profile and the inwardly protruding portion. Similarly, the height He1 is slightly smaller than the transverse distance Dt, thereby allowing the second end segment 324 to be arranged at an angle, for example perpendicularly, between the first leg and the second leg of the other groove profile. Figure 4The second longitudinal end of the channel profile 30 is shown, but the first longitudinal end may have the same configuration, so the first longitudinal end would be Figure 4 Mirror image of the view in .

[0075] Figure 5 A cross section of a groove profile 30 is shown which is in the process of being connected to another groove profile 30' having a first leg 31' and a second leg 32'. As viewed in the direction towards the first longitudinal end, Figure 5 The cross section is a TH plane having a longitudinal position close to the first longitudinal end of the groove profile 30. The groove profile 30 is configured as follows Figure 4 The groove profile shown, however Figure 5 The first longitudinal end and the first end section 323 of the groove profile 30 are shown. Another groove profile 30' is configured as Figure 4 The main part of the groove profile shown, therefore the height Hm' is equal to the height Hm, the free distance Dm' is equal to the free distance Dm, and the distance Dt' is equal to the distance Dt. As can be observed, the height He1 of the first end section 323 enables the first end section 323 to be positioned in the inner space 300' of the other groove profile 30' in a manner that is angled with the first leg 31' and the second leg 32' of the other groove profile 30'. When the groove profile is as Figure 5 When arranged as shown, the groove profile 30 can be rotated about the longitudinal direction indicated by the curved arrow to connect the two profiles, whereby the first end section 323 will snap between the bottom 35' and the inwardly protruding portion 320' of the other groove profile 30'. In this connected state (not shown), the legs of the groove profile 30 and the other groove profile 30' will not extend in parallel. For example, the bottom 35 and the bottom 35' will be slightly inclined relative to each other, and similarly, the first leg 31 and the first leg 31' will also be slightly inclined relative to each other. The material of the groove profile, such as metal, is elastic and / or deformable, thereby allowing the legs to deform when the groove profiles are connected.

[0076] Now go to Figure 6 and Figure 7 , Figure 6 and Figure 7 Shown with Figure 4 and Figure 5 The same view, but showing an embodiment in which the groove profile 20 and the further groove profile 20' are configured as outer groove profiles. The first end section 223 and the second end section 224 are obtained by removing a portion of the second leg 22 including a portion of the inwardly protruding portion 220. The free edge 2240 of the second leg 32 in the second end section 224 is Figure 6The corresponding free edge 2230 at the first end section 223 is not visible in the cross section of FIG. 224 but is indicated by reference numeral 2240 and the height He1 of the second end section 224. Figure 7 As can be seen in Figure 4 and Figure 5 As shown, Figure 6 and Figure 7 The height He1 of the first end section 223 and the second end section 224 is less than the height Hm of the main section of the second leg 32, is substantially equal to the free distance Dm and the free distance Dm' between the bottom 25 and the inwardly protruding portion 220, is less than the distance Dt between the first leg 21 and the second leg 22 of the groove profile 20, and is less than the distance Dt' between the first leg 21' and the second leg 22' of the other groove profile 20'. Figure 6 and Figure 7 The inwardly protruding portions 220, 220' of the outer groove profile in the embodiment are open curling edges, and Figure 4 and Figure 5 The inwardly projecting portions 320, 320' of the inner groove profile shown in the figure are closed curling edges. Therefore, the downwardly facing surfaces of the inwardly projecting portions 220, 220' are located within the open curling edges constituting the inwardly projecting portions 220, 220', such as Figure 5 and Figure 6 As shown, the downwardly facing surface is adjacent to the second leg 22, 22' and the free distance Dm to the downwardly facing surface is evaluated. Figures 4 to 7 It is shown how the channel profiles 20, 30 according to the invention can be used to establish an inside-to-inside connection or an outside-to-outside connection in a manner suitable for drainage. Figure 4 and Figure 5 The inner groove profiles 30, 30' are configured to move in a typical telescopic manner (not shown). Figure 6 and Figure 7 The outer groove profile 20, 20' slides lengthwise in the inner space of the outer groove profile. The groove profile 20 has a distance De between the outward facing surface of the first leg and the outward facing surface of the second leg. The distances De and Dm are constant along the entire length of the groove profile.

[0077] Now go to Figure 8 , Figure 8A portion of an inner groove profile 30 according to the present invention is shown at its first longitudinal end 33, which is adjacent to the longitudinal end of another inner groove profile 30'. A plane P1 divides the groove profile 30 into a first end portion located on the right side of the plane P1, in which the first end segment 323 of the second leg 32 extends, and a main portion located on the left side of the plane P1, in which the main segment 325 of the second leg 32 extends. In this embodiment, the height He1 of the first end segment 323 has been reduced by cutting a portion of the second leg including an inwardly protruding portion away from the second leg. The remaining inwardly protruding portion 320 extends in the main segment 325 of the second leg. The height He1 of the first end segment 323 is measured at the top of the second leg to the free edge 3230, and is less than the height Hm of the main segment measured at the top of the main segment 325 to the free edge 3250. The first end segment 323 extends to the first longitudinal end 33 and has a length Le in the longitudinal direction, which is about 10 cm here. The first leg 31 of the groove profile is provided with a plurality of openings 37, Figure 8 Only one of the plurality of openings 37 is shown, which is arranged to receive a fastener (not shown) for attaching the gutter profile 30 to the roof structure. A further opening 36 is provided in the first leg 31, the purpose of which will be described below. The further gutter profile 30' has the same dimensions as the main part of the gutter profile 30, so that the first leg 31' is equal to the first leg 31, and the second leg 32' is equal to the main section 325 of the second leg 32, whereby the height Hm' is equal to the height Hm.

[0078] Figures 9 to 11 The sequence shows the process of connecting the inner groove profile 30 according to the present invention to another inner groove profile 30'. Fig. 9 , the second longitudinal end 34 of the groove profile 30 is arranged in the inner space of the other groove profile 30', wherein the second end section 324 of the second leg 32 extends perpendicularly to the first leg 31' and the second leg 32' of the other groove profile 30'. The second end section 324 is located on the left side of the plane P2 (and therefore, the second end portion of the groove profile is also located on the left side of the plane P2), while the main section 325 of the second leg is located on the right side of the plane P2 (and therefore, the main part of the groove profile 30 is also located on the right side of the plane P2). The second end section 324 and Figure 8 The first end section 323 shown corresponds to the first end section 323. Fig. 9The groove profiles shown positioned at an angle to each other facilitate the first step of connecting the groove profiles, in which the grooves are arranged to overlap by sliding them. In the next step, the profiles 30, 30' are rotated relative to each other about the longitudinal direction L, whereby a portion of the main section 325 snaps between the inwardly protruding portion 320' of the other groove profile 30' and the bottom (not visible), as shown in FIG. Fig.10 Then, the groove profile 30 is slid lengthwise into another groove profile 30' to achieve Fig.11 Assembled state as shown. Fig.11 As can be observed in the figure, both groove profiles have a plurality of openings 37, 37' in their first legs 31, 31', but the groove profile 30 according to the invention is also provided with another opening 36, which is positioned to align with the opening 37 of the other groove profile 30', which is close to the longitudinal end when the groove profiles are arranged in a correctly overlapping manner and allows the fastener to extend through the two groove profiles through the opening 36. Fig.11 In the assembled state shown, the entire second end section (not visible) overlaps with the other groove profile 30', so that the length of the overlap is Le. As can be observed, in the assembled state shown, the first leg 31 is not parallel to the first leg 31', and the two bottom legs (not visible) are also not parallel, but inclined relative to each other. Therefore, in the overlapping part of the groove profiles, there is a gap between the groove profiles 30, 30' in the height direction. In this embodiment, the groove profile is made of metal plate, aluminum, and the groove profile is elastic, thereby allowing the groove profile to deform slightly in the assembled state. In the case where fasteners (not shown) are inserted through the openings 36, 37', the first legs 31 and 31' will be forced to be closer together. Fig.11 In the embodiment, water is discharged from the groove profile 30 to another groove profile 30', and water does not flow directly into the gap between the groove profiles. In addition, the length Le is sufficient to minimize the risk of water "flowing back" under the groove profile 30. In this embodiment, the length Le is about 10 cm.

[0079] Now go to Fig.12 , Fig.12A system with a telescopic gutter 2' according to the invention is shown, the telescopic gutter 2' having an inner gutter profile 30' and an outer gutter profile 20' connected in a telescopic manner, and an additional gutter profile 30, which is equal in size to the inner gutter profile 30' except for the reduced height of the second leg 32 at the first longitudinal end 33 and the second longitudinal end 34, thereby providing a first end section 323 located to the right of the plane P1 and a second end section 324 located to the left of the plane P2, wherein a main section 325 adjoins the two end sections and extends between the planes P1 and P2. The first end section 323, the main section 325 and the second end section 324 are arranged sequentially along the longitudinal direction L. The additional gutter profile 30 is shown separated from the telescopic gutter in the unassembled state of the system. When the system is in the assembled state, the groove profile 30 will be connected to the inner groove profile 30', which will provide three groove profiles with appropriate overlaps in the direction of water flow (rightward direction). Another additional groove profile (not shown) can be connected to the additional groove profile 30 to provide more than three profiles in sequence. In this case, a second groove profile (not shown) identical to the additional groove profile 30 will be connected by positioning the first end section of the second additional groove profile (not shown) in the main part of the inner groove profile 30 from the second longitudinal end 34. In this case, the overlap between the second additional groove profile (not shown) and the additional groove profile 30 will be twice the length Le.

[0080] Fig.13 Shows something like Fig.12 Another embodiment of the invention, but in which the additional groove profile 30 is arranged as part of an additional telescopic drainage groove, the additional telescopic drainage groove also includes an additional outer groove profile 20, the additional outer groove profile 20 having a first end section 223 located on the right side of the plane P1, a second end section 224 located on the left side of the plane P2 and a main section 225 extending between the plane P1 and the plane P2. The sequence of the four groove profiles connected is shown, in which the additional inner groove profile 30 is connected to the inner groove profile 30' by means of the first end section 323, the inner groove profile 30' is in turn connected to the additional outer groove profile 20 in a telescopic manner, and the outer groove profile 20 is then connected to the outer groove profile 20' by means of the first end section 223. In Fig.12 and Fig.13 In the drawings, the flow of water is to the right, but it will be appreciated that the flow of water could be to the left, in which case the system would be assembled in a mirror image manner using the second end section 224, 324 of the other groove profile.

[0081] Fig.14 and Fig.15A cross-sectional view of an embodiment of a channel profile according to the invention having an alternative cross-section is shown. Fig.14 shows a V-groove profile, while Fig.15 An embodiment with a rounded bottom is shown. Both figures show a height He1 of the first end section 325 which is smaller than the height Hm of the main section 325 indicated by a dashed line. A distance Dt greater than the height He1 is shown together with a free distance Dm between the bottom 35 and the inwardly protruding portion 320 of the main section 325.
