Title: Bracket and method of mounting the bracket

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a roof mounting bracket which has a flat surface and is made of a sheet material and comprises a body comprising a fastener at one end of the body for attaching the bracket to a roof part and at the opposite end of the body a supporting portion, which fastener comprises at least one plate member contiguous to the body along a first side of the plate member.

10 When mounting aids on roofs, different mounting techniques are used depending on the task to be solved. A roof ladder is typically mounted by mounting a roof brace over the roof ridge to which a ladder is attached. Alternatively, steps are attached directly to the roof covering, which entails a risk of the tiles breaking when the step is bolted to the roof plate.

15

When mounting solar cells on a roof, individual solutions are often constructed, typically in the form of a steel frame, which is adhered to the roof structure to which the solar cell is mounted. It is an inflexible solution that does not allow the solar cell to move later without this being associated with great hassle.

20

There are also various systems for mounting snow catchers, where the attachment is also preferably carried out by drilling in the roof structure itself to provide the mounting.

However, another method is disclosed in EP1201844. From this is known a snow catcher, made of a sheet material and comprising an elongated body with a hook at one end of the body gripping a roof plate, and at the opposite end of the elongated body a supporting part for receiving the snow. The construction of the patent in question has the disadvantage that the hook fills a lot during transport of the snow catchers, and during mounting of the snow catcher it is necessary that a roof plate is lifted in order for the hook to enter the overlying roof plate and grab the upper edge of the roof plate that lies below the raised roof plate. This is a difficult task, but also only the roof plate on which the DK 177563 B1 2 snow catcher is mounted when the snow is caught by the support party. Further, the support member is bent in extension of the elongated body, and must necessarily be bent into a side view, triangular in shape, to have sufficient strength under the load of snow.

5

JP 2560115 also discloses a snow catcher which comprises a long narrow surface portion with a portion projecting from the elongated body. This plate part is used for positioning the snow catcher in relation to the individual roof plate, as it grips the edge of the roof plate. In addition, the snow catcher comprises fasteners in the form of 10 holes in the body, such that the snow catcher is screwed to the roof panels through said holes. The snow catcher thus requires holes to be drilled in the roof panels, which is unfortunate as it can in itself cause leaks in the snow when the snow dries, which is why water seeps down under the roof. In addition, the support part which is to catch the snow is wrapped in a side-shaped, L-shaped profile, which is why great strength of the material chosen or, alternatively, other strength-increasing measures is required in order for this upward curved edge to withstand the pressure of the snow. Also, only the roofing plate to which the snow catcher is attached is loaded.

It is the object of the present invention to provide a bracket which does not have the disadvantages of the known products and which constitutes an alternative thereto and which can be used for the establishment of solar cells, roof runners and the like. on roofs. Depending on the field of application, an appropriate unit will be attached to the bracket.

This object is achieved with a bracket of the type specified in the preamble, wherein the fastening means comprises two plate elements, each plate element comprising one with the body longitudinal second and third sides, starting from each their first side, each plate element comprising a fourth side opposite the first side and connecting the second and third sides, and that the two plate elements lie on each side of the body and separated from it by a separator element in the form of a slot / slot in the bracket when the surfaces of the body and plate elements are at the same level and surface parallel, and the plate elements being adapted to form an angle V with the plane surface of the body.

DK 177563 B1 3

In such a construction, the bracket can be placed on already laid roofs without the roof panels having to be lifted off and / or the bracket screwed to the roof panels, which will cause leaks. Since the plate elements of the bracket are bent at an appropriate angle V about 20-30 degrees, preferably about 25 5 degrees relative to the extent of the body, and since the plate elements are resiliently connected to the rest of the snow catcher, the part of the bracket comprising the plate elements can be pressed in below a roof plate, at which the plate elements are pressed up against the body so that they are substantially in level with this.

As soon as the elements are pressed in so far that the elements are free of the underlying roof plate, they sweep out into the pre-bent position. The bracket is now pulled in the opposite direction of the insertion direction, whereby the fourth side of the bracket's protruding plate elements grip a lath and drill into it. In this way, the bracket is firmly fixed and the force is distributed on the ply and not on the more fragile roofing sheets. To the bracket now attached, various assemblies may be connected, such as rods which are attached to the bracket and which may constitute stair steps. In this case, two fittings that are at the same horizontal level will be placed and at least one rod is now attached to the two fittings. A fitting pair is now subsequently mounted at a suitable step distance to the first, and a new step is now established and then still until the required ladder is provided.

If the brackets are to be used for snow catches, brackets will be mounted along the entire edge of the roof at the same horizontal level with a suitable distance between and at least one rod that can be attached to all the brackets, typically by passing through holes in the bracket, which rod will constitute the snowmobile part. Often, 25 more rods will be used to achieve sufficient snow catching.

Since the plate elements are located symmetrically around the longitudinal axis of the body, it is achieved that the bracket is very stable against the leg, the two legs ensuring that the bracket cannot tip. It makes the bracket highly applicable to the above application areas. The bracket can also be used for mounting other elements on a roof, such as signs, solar panels, etc.

DK 177563 B1 4

By spring, it is understood that the plate elements, when bent at the appropriate angle, can be pressed in substantially without being deformed plastically so that they are substantially flush with the body from which they originate and that the spring force is of such a character. that the plate elements project out 5 to the pre-bent angle when the plate elements are again free. The spring force is arranged with a suitable force K, so that the plastic deformation is avoided. The roof part is preferably a lay. The angle V is open towards the support part.

A convenient form comprises that the width of the gap / slot measured between the longitudinal end sides of the body and the longitudinal sides of the respective plate blanks nearest 1 to 8 mm. In this way, an appropriate shape is obtained where, due to the width of the gap, the closing of the gap in the first side area will not have a notch effect, which reduces the risk of the plate elements being torn up.

An appropriate embodiment of the invention comprises the slot / slot ending in the region of the first side, in a rounding having a rounding radius of 1-4mm. In the case where the gap / slit is merely a cut line between the body and the respective plate elements, it is important that the transition between the plate elements and the rest of the bracket does not exhibit notching effect. By ensuring that the transition ends in a rounding and preferably with a rounding radius of 2mm, it is ensured that the plate elements in this area are not torn up.

An appropriate embodiment of the snow catcher comprises that the fourth side comprises retention elements. This results in the element bonding well to the underlying lamina. The retention elements can be designed as saws drilling in with the pointed teeth of the soft wood. They can be shaped like a sharp egg, they can also be made up of a spear-like shape or one to several rams, which drill down into an underlying lair.

DK 177563 B1 5

A convenient embodiment of the invention comprises that the first sides lie at a distance from the end of the gap / slit towards the fourth side, the first side comprising a bending point. In this way, a unique bending of the element is achieved, without the risk of the angle being insufficiently and / or skewed bending far to the front side. In addition, it counteracts the notch effect.

An appropriate embodiment of the invention comprises that the support member is integral with the body and in sheet material, which support at least one protruding member relative to the longitudinal sides of the body, and that the bracket 10 comprises a bending line between the body and the protruding member, and at least one bore therein. protruding party for picking up an aggregate. Hereby it is obtained that the surface of the supporting part, which, when bent, faces the body, forms a substantially perpendicular angle with the surface of the body. The surface itself runs parallel to the longitudinal axis of the body, thereby obtaining great strength in the construction, even when using a relatively weak sheet material such as aluminum. This is because a force on the bent part will have a line of attack parallel to the bend line, and not, as in the known constructions mentioned in the introduction, perpendicular to the bend line. As mentioned, it enables selection of a light material such as aluminum, which is why the snow catchers are easy to transport at the same time as aluminum is a rust resistant material. However, the protruding party may also be two opposite wings. An assembly is installed through the holes in the blades. in the form of one or more tubes. The pipes pass uninterrupted through all the roof mounted fittings mounted in the same horizontal level. The support member and the body are preferably formed into one, for example by punching the entire bracket into a suitable sheet material.

A convenient embodiment of the invention comprises the assembly comprising at least one transverse bar to provide a roof ladder step or a snow catcher. The assembly may comprise a bolt and nut for retaining a suitable structure, such as a solar cell.

A convenient embodiment of the invention comprises that the angle V is preferably 20-30 degrees.

DK 177563 B1 6

A convenient embodiment of the invention comprises that the supporting part and the surfaces of the plate body facing each other form an angle Q which angle Q is preferably 90-100 degrees. In this way it is possible to stack the 5 brackets during transport.

A convenient embodiment of the invention comprises that the angle V is located between the first surface of the body and the plate element, and the angle Q is located between the second surface of the body - opposite the first surface - and the supporting part, which two angles face each other.

A convenient embodiment comprises that the sheet material comprises an aluminum alloy.

A convenient embodiment comprises that the fastener is tongue-shaped or corrugated.

A convenient embodiment comprises that the connection between the plate elements and the body is resiliently arranged with a spring force K.

20

A convenient embodiment comprises that the system against the roof part comprises contact between the roof part and the fourth side.

The invention also encompasses a method of mounting a bracket on a roof, wherein the plate elements of the bracket are extended along their front side to provide an angle V and that its spring sides are brought against the roof part.

A convenient embodiment of the method according to the invention comprises that the support part (s) is bent at an angle Q in the opposite direction 30 of the angle V, that the body is pushed between an upper and a lower roof plate with the plate elements facing the lower roof plate, the plate elements are free of the roof plate, are pulled in the opposite direction of the insertion direction, by which the fourth side of the plate elements grips an underlying lath.

The invention will now be explained in more detail with reference to the drawings, where:

DK 177563 B1 8

FIG. 1A, 1B and FIG. 2 shows an exemplary embodiment of a bracket 1 according to the invention, made in a sheet material of typically 4-5 mm thickness and e.g. in an aluminum alloy. The bracket 1 comprises an elongated body 2, formed in sheet material 5, which body is formed slightly curved at one end 4, and in which a fastening means 3 in the form of plate elements 7 are formed at a distance from the end surface of one end 4. as a substantially tongue-like portion, contiguous to the body 2, cutting / punching two slots 12 such that the slot 12 delineates the body 2 on two sides. The plate elements are in resilient connection with the elongated body 2 at each a first side 8, where typically a bending point 17 is provided in the form of a groove and the plate elements 7 lie symmetrically about the longitudinal axis of the body. From each first side 8 there are two parallel or converging sides, the second side 9 and the third side 10, which terminate and connect at the fourth side 11, which fourth side 11 will typically comprise 15 retention elements 15, for example in that the edge of the fourth side is formed with saws.

The plate elements 7 are thus partially punched out by the body 2 itself and are bent at an angle before use, so that the surfaces 13 20 of the plate elements 7 form an angle of 20-30 degrees, preferably 25 degrees, with the one surface 14 of the body 2 itself; first surface 28. The slots 12 have an extension corresponding to the length of the third side and are defined therein. Thus, the slots terminate in a first region 30 and a second region 31 on each side of the body 2, and at a distance of 2-4 mm from the bending indicator 17. The bending indicator 17 ensures that during bending of the plate elements 7, no distortion occurs. bending / warping of the plate element 7, but this occurs precisely where the bending indicator / groove is applied and without the body 2 itself absorbing cracks. This is due to the extent of the gap and that this gap ends with a rounding radius 16, which rounding radius 16 is typically 1-4 mm, preferably 2 mm. The gap width itself is 1-8 mm, preferably 2 mm.

Opposite to the plate elements 7 at the other end 24 of the body 2, a support part 6 is formed for receiving an assembly. The support part 6 is formed DK 177563 B1 9 as a protruding part 18 and as mentioned is punched out of the sheet material. Subsequently, the protruding portion is bent up so that between its planar surface and the second planar surface 14 of the body 2, ie. its second surface 29, an angle of 90-100 degrees occurs. Since the plate, the protruding part, is bent 5 so that its surface runs parallel to the longitudinal axis of the body 2, great strength is obtained in the construction, since a force on the protruding part 18 will extend parallel to its bending line 19. The force arises in connection with the fitting of the bracket. against a roof and when used for holding the unit 22.

The protruding portion 18 itself comprises 1-2 bores 23, possibly. several which take up the holding assembly 22 typically in the form of tubes. The longitudinal axis of these tubes thus forms an angle of approx. 90 degrees with the 2 longitudinal axis of the body.

FIG. 3A-3C show the brackets during assembly, the resilient plate elements 7 15 being bent at the aforementioned angle of about 25 degrees, and the protruding part 18 also being bent in the opposite direction by the bending of the resilient parts and at an angle of 90 degrees. -100 degrees. The bracket 1 is now slid into one roof plate with one end, and the underlying roof plate will cause the resilient member to be pushed upwards towards the overlying roof plate and in principle contribute to lifting it, so that insertion is facilitated. The angle between the body and plate element is open in the direction opposite to the insertion direction.

FIG. 3B shows the bracket when it is brought into final position, the plate elements 7 flushing out as soon as they are released from the underlying roof plate 26.

25 The bracket is now pulled in the opposite direction of the insertion direction, whereby the fourth sides 11 of the plate elements 7, which preferably also include the aforementioned retention elements 15, bore into the underlying laid 5. In this way, a good construction of the bracket and a good distribution of power are ensured. .

In FIG. 3C, the bracket is used as a snow catcher, where the snow catcher retains the snow, in which a bore assembly 22 in the form of pipes is provided in the bores 23 of the projecting part 18.

DK 177563 B1 10

FIG. 4A and 4B show a perspective view of a set of pre-assembled snow catchers on a roof, in which, in FIG. 4A roof plates 26 are different from those of FIG. 4B roofing 26. This is to demonstrate that the snow catcher can be used regardless of the roof plate types concerned, it being essential that there are transverse layers underneath the roof plates 5 which the plate elements 7 can drill into and secure the fastening. of the snow catcher. The snow catcher is of course positioned so that it is arranged in the same row of roofing plates, so that the holding unit 22 in the form of pipes can be pushed continuously through all the snow catcher bores 23 in the protruding part. The snow catcher is shown with just one protruding party 18, but could include 2 opposite protruding parties, which would typically take place for the snow catcher to be placed in the final area of the roof, ie. along the right and left edges of this.

FIG. 5A shows the bracket according to the invention for providing steps on a roof and FIG. 5B shows that in FIG. 5A, mounted on a roof. Two brackets 1 are located at the same horizontal level on a roof 25 and spaced apart, which is suitable for a footstep ie. about 30 - 40 cm between them. Through the two bores 23 of the two bending projections 18, a holding assembly 22 in the form of 2 parallel pipes is pierced. In addition, a ladder step is provided which is mounted on the roof 25 as shown in FIG. 5B. The plate elements 7 of the fittings 1 drill down with their fourth side into the same lath with the retention elements belonging to the fourth side. The body 2 is thus located on the upper side of the roof plate 25 and helps to distribute the pressure, while the retention elements 15 ensure that the step does not progress with the inclined tagpart.

25

FIG. 6 shows steps prepared as shown in FIG. 5A and B and wherein the steps 22 in the form of pipes are located at the same vertical level, thereby providing a roof ladder 20. The distance between the steps is in the order of 20-40 cm depending on the slope of the roof and the distance between the underlying laths. The more weight the 30 fittings are loaded with, the more they drill down into the underlying bed.

DK 177563 B1 11

The mounting typically takes place by bending the plate elements 7, thus constituting the retaining member, to the angle of about 25 degrees in the pre-pressed grooves / bending guides 17, which are approx. is 15-30 mm long, depending on roof type. The bracket is led up through the roof panels and snaps down as a result of its resilient construction and locks around the lath. One or two of the longitudinal pipes, which constitute holding assemblies 22, are mounted and which are held by the protruding part (s). If the bracket is used as a snow catcher, double pipe holders are mounted on each side of the snow catcher bracket in end joints, while in the middle brackets the pipe holders are mounted right / left to protect against side skidding.

10

The pipes themselves are fastened to the snow catcher bracket using machine screws. Due to the selected dimension, 5 mm machine screws are preferably used.

The bracket is preferably made by punching the mold into a 2 mm thick stainless steel sheet material.
