Description

A SEAM BRACKET ARRANGEMENT AND METHOD FOR

MANUFACTURING A BRACKET PART

TECHNICAL FIELD

The present disclosure relates to a seam bracket arrangement and a method for manufacturing a seam bracket arrangement.

BACKGROUND

Seam brackets are commonly used to attach electronic equipment to seams of roofs. For example, seam brackets can be utilized to attach solar panels to roofs, thus the solar panel can be attached to seam brackets which in turn are attached to the rooftop.

A typical solar panel installation is comprised of a grid system employing a plurality of individual panels that jointly form a grid over a surface of the roof of a house.

Conventionally, the seam bracket arrangements used for such system fail to provide convenience in assembly while being compact. Thus, preferably, a seam bracket arrangement should be convenient to assemble to a roof, while also being construed in a manner to be compact, thereby reducing material costs.

Thus, seam bracket arrangements in the present art fail to fulfil requirements of being dimensioned to provide convenience in assembly while being compact.

Specifically, seam bracket arrangements fail to fulfil requirements of convenience and compactness while maintaining load-bearing capabilities.

Thus, there is room for seam bracket arrangements in the present art to explore the domain of providing a seam bracket arrangement that provides improved convenience when being installed and compactness. Specifically there is room to provide a seam bracket arrangement that allow for a convenient assembly while being compact and maintaining load-bearing capabilities. Thus, even though previous solutions may work well in some situations, it would be desirable to provide a seam bracket arrangement that address requirements related to improving convenience in installation while being compact and maintaining and load-bearing capabilities.

SUMMARY

It is therefore an object of the present disclosure to alleviate at least some of the mentioned drawbacks to provide an improved seam bracket arrangement that is more convenient in installation while being compact.

This and other objects, which will become apparent in the following, are achieved by a seam bracket arrangement and a method of manufacturing a seam bracket as defined in the appended claims.

The present disclosure relates to, in one aspect, a seam bracket arrangement for attaching electronic equipment to a seam of a metal roof, comprising a pair of bracket parts (may be referred to as a first and a second bracket part), each of which comprises a bracket body comprising a lower edge and an upper edge being divided into (comprising) a first upper edge portion and a second upper edge portion. Further comprising an equipment attachment flange protruding from said first upper edge portion of said bracket body and a seam engagement portion protruding from a lower edge of said bracket body for engaging one side of a seam of a metal roof. The flange extending along the length of said body. Further, at a connected state (i.e. when the bracket parts are attached to each other), said pair of bracket parts are connected to each other by means of a mechanical fastening means extending through both bracket bodies from which a compressive force is translated into a clamping force at the seam engagement portions of the two bracket parts. Each equipment flange comprises a connecting portion said connecting portion contacting said second upper edge portion of the other bracket part of said pair of bracket parts. Furthermore, the seam engagement portions extend towards each other so to jointly provide said clamping force.

An advantage of the seam bracket arrangement is that the equipment attachment flange protrudes from a first upper edge portion of each bracket body and is, in the connected state, in contact with the second upper edge portion of the other bracket body, thus providing a convenient yet compact assembly of the seam bracket arrangement.

The equipment attachment flange of each bracket body may connect to no more than 50% of a total length of said upper edge thereof, such that said pair of bracket parts can mate with each other.

An advantage of this is that it allows the two bracket parts to be attachable to each other in a secure manner while being substantially identical in their shape. Thus, allowing manufacturing of the bracket parts to be much easier.

Each equipment attachment flange may comprise, at said connecting portion, at least one corrugation, the corrugation being, at said connected state, mated with corresponding mating portions of second upper edge portions of the other bracket part of the other equipment attachment flange of said pair of bracket parts.

This advantageously allows the bracket parts to lock on to each other in a more secure manner, especially in the longitudinal direction.

The pair of bracket parts may be identical. Advantageously allowing for a more efficient and cost-convenient manufacturing of the seam bracket arrangement. In some aspects only the connecting portion and seam engagement portion are identical. In some aspects, also the equipment attachment flanges are identical.

Each equipment attachment flange may comprise a fastening hole extending in the direction of said upper edge, in other words the fastening hole is oblong in the direction of said upper edge (x1 ). A benefit of that the fastening hole extends in the direction of said upper edge is that it allows for increased flexibility in the attachment of electronic equipment to said seam bracket arrangement.

In some aspects herein, an outer edge of the fastening hole extending parallel to said upper edge, is parallel to a flange edge of said attachment flange.

An advantage of this is that it allows for an intermediate attachment means, that is arranged to connect between said electronic equipment and the seam bracket arrangement, to be slidably adjusted along the longitudinal direction, thus providing improved flexibility. Thus, the seam bracket arrangement may further comprise an intermediate attachment means that has a U-shape and is arranged to mate/partially enclose to said attachment flange (in y1 direction) for securing an electronic equipment to the seam bracket with a fastening means being secured to the U-shape from opposing sides of the fastening hole.

Each of said fastening holes may extend in a longitudinal direction, wherein said fastening holes are offset in said longitudinal direction relative each other at said connected state. An advantage of this is that it provides further increased flexibility when attaching an electronic equipment to the arrangement as the play is increased. The offset fastening holes allow for a greater area/variability of attachment in the longitudinal direction. For each bracket part, the seam engagement portion and said attachment flange may protrude towards a common direction. This allows for a more compact arrangement when in said connected state as the attachment flange will overlap the other bracket part when connected.

An upper portion of each bracket body, at which said upper edge is located, may be offset in a horizontal direction relative a lower portion of said bracket body, at which said lower edge is located, allowing for the upper portions to contact when at said connected state. This ensures improved stability in the connected state of the seam bracket arrangement as it allows for the respective upper portions to contact each other, improving load distribution.

Each bracket body may be corrugated. This the corrugations act as stiffeners and enable the bracket body to withstand the pre-tension generated by the mechanical fastening means.

There is further provided a method for manufacturing a seam bracket arrangement comprising:

-providing at least one metal sheet

-forming, by said at least one metal sheet, a pair of bracket parts, each of which comprises a bracket body comprising a lower edge, and an upper edge being divided into a first upper edge portion and a second upper edge portion. Further, comprising an equipment attachment flange protruding from said first upper edge portion of said bracket body and a seam engagement portion protruding from a lower edge of said bracket body for engaging one side of a seam of a metal roof.

The forming may be press formed.

There may also be provided a method for manufacturing a bracket part for a seam bracket arrangement comprising: -providing at least one metal sheet -forming, by said at least one metal sheet, a bracket part that comprises: a bracket body comprising a lower edge, and an upper edge being divided into a first upper edge portion and a second upper edge portion, an equipment attachment flange protruding from said first upper edge portion of said bracket body, a seam engagement portion protruding from a lower edge of said bracket body for engaging one side of a seam of a metal roof.

The present disclosure also provides a seam bracket arrangement according to another aspect. The seam bracket arrangement comprising a pair of bracket parts, each of which comprises a bracket body comprising a lower edge, and an upper edge. Further, comprising an equipment attachment flange protruding from said upper edge of said bracket body. Further, comprising a seam engagement portion protruding from a lower edge of said bracket body for engaging one side of a seam of a metal roof. Further, at a connected state, said pair of bracket parts are connected to each other by means of a mechanical fastening means (e.g screw, bolt, nut, or any other fastening means) extending through both bracket bodies from which a compressive force is translated into a clamping force at the seam engagement portions of the two bracket parts. Moreover, said upper edges of said pair of bracket parts are in contact with each other in said installed state. Further, in the installed state the seam engagement portions extend towards each other so to jointly provide said clamping force.

The seam bracket arrangement of the aformentioned aspect provides at least the same advantages as the previous aspect herein. The equipment attachment flange of each bracket body may connect to at least 50% of a total length of said upper edge thereof. Preferably, at least 75%.

Advantageously, providing a greater area for fastening.

Moreover, the pair of bracket parts may be identical.

Moreover, each equipment attachment flange may comprise a fastening hole, preferably extending in the direction of said upper edge. Preferably, the equipment attachment flange of each bracket part comprises a plurality of fastening holes distributed along the length of the equipment attachment flange.

Accordingly each of said fastening holes may extend in a longitudinal direction, wherein said fastening holes may be offset in said longitudinal direction relative each other at said connected state.

Moreover, a portion of each bracket body, at which said upper edge is located, is offset in a horizontal direction relative a lower portion of said bracket body, at which said lower edge is located.

Further, each bracket body may be corrugated.

Further, the seam engagement portion and the attachment flange of each bracket part may protrude in different directions relative eachother.

Accordingly, in said installed state, each attachment flange is non-overlapping (in horizontal direction) relative the edge of the other bracket part. An advantage of this is that the attachment flange of each bracket part may extend along the full length of the bracket part resulting in more flexibility when attaching equipment to it.

Further, for each bracket part, said upper edge comprises a first and a second opposite side portion, wherein said first side portion comprises a protruding locking tooth, wherein at said installed state, each locking tooth of each bracket part is in contact with/mated with an upper edge of the other bracket part at said second side portion (of the other bracket part). To specify, the bracket part may be referred to as a first and a second bracket part. Hence, the locking tooth of the first bracket part may be in contact with/abutting/mating the upper edge of the second bracket part at said second side portion of said second bracket part. Side portion may extend longitudinally along a maximum of 20% of the total length of each bracket part, preferably a maximum of 15% of a total length thereof. More preferably, a maximum of 10% of a total width thereof. Accordingly, each tooth may extend along a maximum of 20%, or 15% or 10% of a total length of the corresponding bracket part.

Further, each locking tooth of each bracket part may, in said installed state, also be in contact with an underside surface of said equipment attachment flange of the other bracket part.

An advantage of this is that the locking teeth then secures the bracket parts together along a height direction of the arrangement.

Further, for each bracket part said locking tooth may comprise a tooth indentation arranged to mate with/abut a perimeter portion (the perimeter portion defining the thickness of the connecting portion) of a connecting portion of said equipment attachment flange of the other bracket part, said tooth indentation extending in a longitudinal direction, allowing the locking tooth to, in said installed state, secure the bracket parts in a direction perpendicular to said longitudinal direction.

The tooth indentation allow for a better fit between said tooth and the connecting portion resulting in that the bracket parts are better secured.

Further, for each bracket part said perimeter portion of each attachment flange may comprise an indentation arranged to mate with a corresponding tooth indentation in said installed state.

Further, for each bracket part, the locking tooth extend in a direction common to the direction of the attachment flange.
