Description

[0001] The invention relates to a device for attaching a gutter to a roof covering according to the preamble of claim 1, 2 or 3.

[0002] DE 20 2018 005 953 U1 relates to a mounting bracket for a sandwich panel with alternating high and low ribs arranged side by side and extending in a longitudinal direction. The mounting bracket comprises a central web extending in the longitudinal direction and having approximately the width of the high rib at its upper end, and a pair of lateral tabs connected to each other via the central web and arranged at an angle to the central web such that they approximately correspond to the contour of the high rib flanks of the sandwich panel's high rib, allowing the tabs to be placed onto the high rib with the central web. The mounting bracket also includes a retaining element connected to the central web or one of the tabs, extending at one end of the mounting bracket transversely to the longitudinal direction and at an angle to the central web.The retaining part is designed in such a way that an attachment, in particular a gutter hook for a roof gutter, can be detachably attached to it.

[0003] Manufacturing the mounting bracket with its central web and angled tabs, as well as attaching it to the high rib with four fixing screws, is a complex process. The gutter hook is specially shaped and features a bend to ensure the gutter is mounted offset towards the building. The use of a standard gutter bracket is not intended.

[0004] DE 10 2018 121 628 A1 relates to a device for attaching roof gutters to roofs, in particular building roofs, comprising a first fastening device which can be attached to a region of the roof by means of at least one first fastening element, wherein at least one element of this fastening device extends in a first direction when mounted on the roof. The device includes a support device for carrying the roof gutter, wherein this support device has a mounting section which can be attached to the first fastening device by means of at least one second fastening element, wherein this mounting section extends in a second direction when mounted on the roof, which preferably differs from the first direction. The support device has a retaining section for holding the roof gutter.

[0005] German patent DE 20 2017 006 366 U1 relates to a gutter mounting bracket for sandwich panels. The mounting bracket consists of two parts: an upper edge section and a lower edge section. The upper edge section comprises a first section, which has a trapezoidal cross-section and is placed over the high rib on the eaves side and screwed in place laterally. It also includes a second section in the form of a metal extension, which is bent perpendicular to the first section and rests against a front edge of the sandwich panel. The lower edge section is an angle bracket. One leg of the lower edge bracket is slid onto the metal extension until a second leg rests against the underside of the sandwich panel and is screwed to it. A gutter bracket is then attached to the lower edge section.

[0006] EP 2 463 455 B1 relates to a mounting and fastening device for a building accessory, such as a gutter bracket, on a roof covering. The mounting device comprises a bracket holder and a U-shaped clamp, which are integrally connected. The U-shaped clamp can be slipped over an edge of the roof covering and fastened to this edge. The U-shaped clamp comprises two legs, which are straight, parallel, and of equal length in cross-section, designed to elastically and directly enclose the edge of the roof covering under the influence of a clamping force exerted on the legs after the edge has been pressed between the legs of the clamp, with the inner surfaces of the legs coming into direct contact with the respective upper and lower sides of the edge of the covering.

[0007] No screws are used for fastening. Due to temperature fluctuations, the clamp fastening can loosen, so there is a risk that the fastening device will slip off the roof covering.

[0008] A gutter bracket is attached to the bracket with a screw connection that is slidably mounted in a longitudinal slot running along the bracket. The bracket has a U-shaped cross-section to prevent the gutter bracket from twisting during installation. The screw connection is solely friction-fit, so some rotation during installation cannot be ruled out.

[0009] Based on this, the present invention aims to further develop a device of the type mentioned above in such a way as to simplify its manufacture and assembly. Twisting of the gutter support and rotation of the screw connection of the gutter support are to be avoided. The device should also be easily adaptable to different roof pitches and / or different heights of sandwich panels.

[0010] According to one aspect of the invention, the fastening section is a flat profile section in which the openings for the fastening means are formed, wherein, in the assembled state, the flat profile section rests exclusively on the web of the high rib and the fastening means engage exclusively via the web in the high rib. The flat profile section can be manufactured easily and securely and material-efficiently mounted by preferably two fastening screws.

[0011] Preferably, the flat profile has a sealing element, such as an EPDM gasket or cellular rubber (sponge rubber), along one underside. This sealing element, in the form of a flat profile gasket, can preferably be pre-assembled and fixed in place by the fastening screws or bonded to the underside. The fastening screws are also integrated into the sealing element, eliminating the need for separate assembly.

[0012] The fasteners are preferably designed as screws, such as sheet metal screws or wood screws, with a screw drive such as external hexagon, internal hexagon, slotted drive, cross-head drive, Torx drive or spline drive, and preferably with a sealing washer.

[0013] The gutter support bracket is particularly preferably formed in one piece from a flat profile, such as a flat steel profile, flat copper profile, or flat aluminum profile, which is preferably sheathed or coated, e.g., galvanized. The flat profile section forms a first leg of the gutter support bracket, from which a second leg extends, stretching vertically along a front edge of the roof covering when installed. A third leg extends from the second leg, oriented parallel or substantially parallel to the first leg and running beneath the roof covering when installed. The retaining section for the gutter support extends from the third leg. The gutter support bracket is thus a molded part that can be easily manufactured from a flat profile material by bending.

[0014] According to an independent inventive aspect, the holding section comprises an elongated hole extending longitudinally in the holding section, in which a first machine element, such as a carriage bolt or nut, is received, which is positively engaged, in particular rotationally secured, in the elongated hole, wherein preferably the first machine element rests against a building-side surface of the holding section with a stop, such as a bolt or nut head, and has a square shoulder which is guided rotationally secured in the elongated hole, wherein the first machine element has a threaded stud or an internal thread which interacts with an internal thread or threaded stud of a second machine element, such as a nut or bolt, wherein a threaded stud of the first or second machine element is guided through a bore of a mounting section of the gutter support and engages in the internal thread of the first or second machine element.to fix the gutter support to the holding section.

[0015] A carriage bolt is preferably accommodated in the elongated hole. The bolt's head rests against a building-side surface of the mounting section and it has a square shoulder that is securely guided within the elongated hole. This prevents the bolt from twisting during installation. The carriage bolt has one end that passes through a bore in a mounting section of the gutter support and accepts a hexagonal nut, which secures the gutter support to the mounting section.

[0016] In order to form an anti-rotation device, it is provided, according to a further independently inventive aspect, that the channel support has at least one projection on a mounting surface facing the holding section, which engages in the elongated hole in the assembly state and forms the anti-rotation device.

[0017] Particularly preferred is at least one projection, a form of connection such as a rivet, screw, cold-formed or welded connection, by means of which a retaining flag known per se for the gutter is fixed to the gutter support.

[0018] Alternatively, at least one projection can be a feature or ridge formed by cold forming, such as stamping, on the assembly section. Preferably, the assembly section has at least two projections.

[0019] To further simplify assembly, in particular to allow the use of only one tool, it is provided that the fastening screws and the machine elements of the screw connection for fastening the gutter support have the same screw drive, such as external hexagon, internal hexagon, slotted drive, cross-recessed drive, Torx drive or splined drive, and in particular the same wrench size.

[0020] The device can particularly preferably be designed as a pre-assembled set comprising the gutter support holder, the seal, the fastening means and the pre-assembled gutter support, wherein the second leg of the gutter support holder has different lengths to adapt to different designs of sandwich panels.

[0021] Another independently inventive aspect concerns a mechanism by which an angle spanned between the web of the high rib and the flat profile fastening section or between the flat profile fastening section and the holding section can be adjusted.

[0022] The mechanism can be an adjusting device, such as an adjusting screw, which can be subjected to force from the first leg and / or the second leg against the holding section in order to bend it relative to the first or second leg.

[0023] The gutter support holder is preferably bent in one piece from the flat profile, wherein a bend between the third leg and the holding section is formed as a predetermined bending point, wherein preferably a predetermined bending edge is incorporated into the material, as is formed, or the elongated hole formed in the holding section extends over the bend into the third leg.

[0024] The mechanism can also be at least an intermediate element, such as a wedge, sleeve or sealing element, which can be inserted between the flat profile section and the web of the high rib, and by means of which an inclination of the flat profile section relative to the web of the high rib can be adjusted.

[0025] According to an inventive aspect, the invention relates to a device for fastening a gutter to a roof covering, comprising a gutter support bracket with a fastening section extending longitudinally along the roof covering in the assembly state, wherein the fastening section has openings, such as bores, for the passage of fastening means, such as screws with sealing rings, by means of which the gutter support bracket is fastened to the roof covering, and a retaining section extending vertically in the assembly state, to which a gutter support is detachably attached.

[0026] The provision is that the holding section has an elongated hole extending in the longitudinal direction of the holding section and that a rotationally secure screw connection is arranged in the elongated hole, by means of which the channel support can be fixed to the holding section.
