Abstract

A packed installation kit for use in the installation of a roof window system comprising two window units, said installation kit comprising a number of installation assemblies each including one or more components, where the components of a first set of installation assemblies are accommodated in a first packaging comprising a box shaped as a rectangular prism, preferably of corrugated cardboard, and the components of the first set of installation assemblies of the installation kit are accommodated in the first packaging either as they are, or partially or entirely packed in a sub-packaging of cardboard or paper material.

Description

DK 181229 B1 1

Technical Field

The present invention relates to a packed installation kit for use in the installation of a roof window system as defined in the preamble of claim 1.

Background Art

Roof windows to be installed in inclined roof surfaces come in a variety of types, and are either installed as stand-alone window units, in which all sides of the roof window border on the roofing, or in configurations in which several window units are built together to combine into larger arrays providing a larger light influx into a room of a building, and in which only outer sides of the outermost window units border on the surrounding roofing.

Applicant's pending DK applications with application numbers PÅ 2020 70877, PA 2020 70878, PA 2020 70879 and PA 2020 70880, which were all filed on 30 December 2020, show and describe roof window systems comprising two window units configured to be built in side by side in a roof structure. To facilitate installation, a number of assemblies are supplied, including support, insulating, stabilizing and cover assemblies. Additionally, auxiliary equipment such as underroof collars and vapour barrier collars are typically provided as well. While such assemblies are of great assistance to the installer, the various assemblies and the auxiliary equipment are typically provided separately and independently from the window units themselves,

Since each assembly in turn includes a variety of differently sized components, logistical challenges in delivery of such a roof window system are substantial.

Furthermore, when installing windows in a roof, it is vital to ensure that the window units themselves are securely attached to the roof structure and that the joint between the window units and the roof structure is properly weather proofed. It is therefore important that all components of roof window products, such as the roof window itself or a flashing assembly for a roof

DK 181229 B1 2 window, are used and are used in the right way. To facilitate this, the components are typically arranged in the box in an intended order of use and small components, such as screws, are kept in plastic bags. Furthermore, blocks of expanded polystyrene or similar shock absorbing material are used for protecting the product and/or for keeping the components in the intended position within the box. An example of a packed roof window, where these principles are used, is known from EP2748071B1 and an example of a packed flashing assembly for a roof window is known from EP1710163B1.

However, combined with an ever-increasing awareness of environmental considerations and the wish to reduce or even eliminate the climate footprint of products and their packaging, there is a need for a possibility of delivering products in a more environmentally friendly way.

Summary of Invention

With this background, it is an object of the invention to provide a packed installation kit, which has a smaller climate footprint, without increasing the risk of errors in the installation of the product and maintaining a good protection of the components of the installation kit during transportation.

This and further objects are achieved with a packed installation kit of the kind mentioned in the introduction, which is furthermore characterised in that the length of the first packaging in the length direction is selected in accordance with the length of a longest component of the first set of installation assemblies, that a second installation assembly comprises a stabilizing assembly with components comprising two stabilizing rails, each stabilizing rail having a length which is shorter than the length of the length of the first packaging in the length direction, and that longitudinal ends of the stabilizing rails are accommodated in sub-packagings comprising open cardboard boxes of cardboard or paper material.

By the provision of a suitably shaped first packaging and by accommodating the components either as they are or packed in paper-based materials only, it has been made possible to not only reduce the total amount of packaging material, but also to render the packaging suitable for easy

DK 181229 B1 3 recycling. In practice, this has the effect that the likelihood of the packaging material actually being recycled instead of just being disposed of as combustible waste is increased significantly, thus contributing to the overall sustainability of the roof window system.

Selecting the length of the first packaging in accordance with the length of the longest component, reduces the amount packaging material used for the packed installation kit. When the selecting the length of the first packaging in accordance with the length of the longest component, the length of the first packaging corresponds to or slightly exceeds the length of the longest component. In this way, the size of the first packaging is kept low, reducing material use for the packed installation kit. When the length of the of the longest component(s) of the first set of the installation assemblies corresponds to or slightly exceeds the common height of the roof window system, the first packaging will have a size corresponding to the size of a packed roof window unit of the roof window system, which may be advantageous when storing, shipping and/or handling the packed installation kit along with the packed window units. The longest components among the components of the first set of installation assemblies may in some embodiments be side members of an insulating frame assembly, which side members extend along the sides of the windows units of the roof window system, when the roof window system is mounted in a roof structure.

At the same time, the stabilizing rails of the stabilizing assembly are packed in the cardboard boxes at their longitudinal ends, thus protecting not only the stabilizing rails themselves, but also other components within the first packaging from possible damage due to contact with the stabilizing assembly.

In a presently preferred embodiment, the components of the second installation assembly are fixated to the first packaging by at least one strip of adhesive or glue interacting with the open cardboard boxes. In this way, the components of the second installation assembly, i.e. the stabilizing rails of the stabilizing assembly including associated components, are held safely in position during transportation.

In another presently preferred embodiment, the components of the

DK 181229 B1 4 second installation assembly are located substantially in parallel to the side edges of the first packaging and function as positioning elements relative to components of a first installation assembly in the width direction of the first packaging. In this way, separate fastening of the components of the first installation assembly is made redundant, since these components may be held in place by the components of the second installation assembly in combination with one or both of the open cardboard boxes and the first packaging itself.

In a preferred development of this embodiment, at least one of said open cardboard box(es) is folded to form an upstanding wall portion facing the components of the first installation assembly. This provides for a mechanically simple solution of providing an abutment surface to block movement in the width direction of the first packing.

It is to be understood that while paper and cardboard are usually made from wood-fibres, other plant fibres including fibres originating from straw, bamboo, bagasse, esparto, other grasses, hemp, flax, and cotton may also be used, including combinations of different types of fibres.

By fixating components of an installation assembly or the sub- packaging thereof to the first packaging in the supply condition, the components are kept in their intended place and protected in the first packaging. By using strips of adhesive, it is possible to provide a suitably secure fastening of the components to the first packaging, with a small amount of adhesive or glue. When paper-based material is recycled, certain amounts of non-paper components, such as adhesive or glue, are allowed for certain grades of recycled paper-based material. Hence, by temporarily fixing components to the first packaging using strips of adhesive, and thus low amounts of adhesive, allows the packaging of the installation kit to be recycled as high-grade paper-based material. The amount of adhesive or glue is preferably comparatively low, e.g. the mass of adhesive or glue is low compared to the mass of packaging, such as less than 2 %, less than 1.5 %, less than 1 %, less than 0.5 % or even less than 0.1 % by weight.

When a component or sub-packaging thereof functions as a positioning element for another component, it restricts the movement of the

DK 181229 B1 other component in the first packaging, keeping the component in place which reduces the risk the components being damaged during shipment and handling. For example, one or more components of a first installation assembly may be wedged in between a side of the first packaging and a sub-packaging 5 of a second sub-assembly. In a development of such an embodiment, the component or sub-packaging thereof which functions as a positioning element, may be temporarily fixated to the first packaging by at least one strip of adhesive or glue. By using some of the components as positioning elements for freely accommodated components among the installation assemblies, it is possible to reduce the use of adhesive or other packaging elements used to keep the components in place in the first packaging. This contributes to an improved recyclability of the packaging and a reduction in overall packaging material used, reducing the climate footprint of the packed installation kit.

In presently preferred embodiments, the installation kit furthermore comprises auxiliary equipment. By providing the auxiliary equipment in the first packaging, the risk of logistical issues in the shipping and supply of the installation kit is reduced, as fewer units need to be handled separately.

Furthermore, it reduces the amount of packaging material needed, compared to auxiliary equipment which is packed separately from the installation assemblies.

In presently preferred embodiments, the underroof collar is packed in a plastic bag intended to function as a collection element for waste, in particular waste of plastic material during installation of the roof window system. To indicate this secondary function, the plastic bag is provided with a label comprising a recycling logo.

Other presently preferred embodiments and further advantages will be apparent from the subsequent detailed description and drawings.

Description of Embodiments

Referring initially to Fig. 1a, which shows a perspective view of a packed installation kit 100. The installation kit 100 has a first set of installation assemblies 4, 5, 6 7, 8 which are accommodated and packed in a first packaging 101. The first set of installation assemblies includes a first installation assembly which is here an insulating assembly 5, a second installation assembly which is here a stabilizing assembly 6, a third installation assembly which is here a support assembly 4 including four mounting brackets, a fourth installation assembly which is here a cover assembly comprising receiver brackets 7 and a fifth installation assembly which is here a cover plate 8.

The first packaging 101 further accommodates auxiliary equipment, here comprising an underroof collar 96, a tape roll 96a, a vapour barrier collar 97 and a gutter element 98.

The packed installation kit 100 is in Fig. 1a shown in a condition where the first packaging 101 is open, allowing the components accommodated therein to be seen. When the packed installation kit is shipped and supplied the first packaging will be closed, providing the installation kit in a supply condition.

The first packaging 101 is a box which in its closed condition, shown in Fig. 1b, is shaped as a rectangular prism or cuboid. The first packaging 101 is made of

DK 181229 B1 8 corrugated cardboard, which is sometimes called corrugated fiberboard. As can be seen the insulating assembly 5 is accommodated in the first packaging 101 as is, that is the components of the assembly are not packed in a sub- packaging nor is it fixated to the first packaging 110, whereas the support assembly 4, receiver brackets 7 and cover plate 8 are packed in respective sub-packaging of cardboard or paper material.

Referring now to Fig. 2a to 2d, which shows perspective views of a second set of installation assemblies 3 of the installation kit 100 being packed in a second packaging 103. Fig. 2a thus shows a second set of installation assemblies 3 and a second packaging 103 in a non-packed state, Fig. 2b shows the assemblies 3 and second packaging 103 during packing, and Fig. 3c shows the installation assemblies 3 packed in second packaging 103 in a supply condition. The second set of installation assemblies is here embodied by a support assembly 3 having two components: an upper support beam 31 anda lower support beam 32. When packing the support assembly 3, the upper and lower support beams 31, 32 are positioned side-by-side extending along each other as shown in Fig. 2a., and thereby provide a rectangular unit of length

L3, width B3 and height H3. In this embodiment the height H3 is a common height and the length L3 is a common length of the upper and lower support beams. The second packaging 103 is a rectangular telescopic tube packaging which has a first part 1031 and a second part 1032. The first and second part 1031, 1032 of the second packaging are each a hollow rectangular box with one open end for receiving the support assembly 3. The first part 1031 has first length L1, first width B1 and first height H1 and the second part has second length L2, second width B2 and second height H2. The internal dimensions of the first part 1031 are such that one end the components of the support assembly 3 can be inserted into the first part 1031 as shown in Fig. 2b, where the support assembly 3 is partially accommodated in the first part 1031 of the second packaging. Similarly, the internal dimensions of the second part 1032 are such that the opposite end of the components of the support assembly 3 can be inserted into the second part 1032 as shown in Fig. 2c and Fig. 2d, whereby the remaining part of the support assembly 3 is accommodated in the

DK 181229 B1 9 second part 1032 of the second packaging. Furthermore, the internal height and width of the second part 1032 are greater than the first height L1 and first width W1 of the first part 1031 respectively and the sum of the first length L1 and second length L2 is such that the two parts of the second packaging 103 overlap when the support assembly 3 with length L3 is packed therein, i.e. in the supply condition. Hence, the sum of first length L1 and second length L2 exceeds the length L3 of the support assembly L3. The internal height and internal width of the second part 1032 are may be selected such that the external surfaces of the first part 1031 engages the internal surfaces of the second part 1032, providing a snug fit in the supply condition. The second packaging 103 is in this embodiment made of corrugated cardboard. The packed installation kit 1 according to the invention can include both the first set of installation assemblies packed in the first packaging 101 and the second set of installation assemblies packed in the second packaging unit 103.

Referring now to Figs 3 to 6 which show a roof window system 1 having two window units 11, 12 being installed side-by-side in an inclined roof structure 2 using the components of installation assemblies and auxiliary equipment of a packed installation kit according to the invention. In Fig. 3 to 4 the roof window system 1 is shown from the exterior of the building and in Fig. 3 the first window unit 11 is mounted in the roof structure 2 and the second window unit 12 is being mounted next to the first window unit 11. In the mounted condition the roof window system 1 has combined width W and common height H, both of which are seen to extend in parallel with the plane of the roof structure 2. The roof window system 1 is being installed using support assembly 3, mounting brackets 4, insulating assembly 5 and stabilizing assembly 6. As can be seen the insulating frame assembly 5 is a frame surrounding the roof window system in the mounted position and the length of the side members of the frame slightly exceeds the common height H of the roof window units. In Fig. 4 the both window units 11, 12 of the roof window system 1 are mounted in the roof structure 2 and auxiliary equipment from the packed installation kit 1 according to the invention is being installed. The auxiliary equipment is here an underroof collar 96 which is mounted around the roof window system 1 and a gutter

DK 181229 B1 10 element 98.

Figs 5 and 6 show views of the roof window system 1 of Fig. 4 as seen from the interior of the building. Fig. 5 shows the roof window system when the vapour barrier collar 97 is installed after having been unpacked from sub- packaging 197 which is here a plastic bag. Fig. 6 shows receiver brackets 7 being installed to receive and mount the cover plate 8.

The process of packing the installation kit 100 in the first packaging 101 will be described with references to Figs 7 to 21 which show sequential steps of packing the components of a first set of installation assemblies and auxiliary equipment in the first packaging 101. The figures do not necessarily represent sequential packing progression of the same installation kit but may in some case demonstrate the sequential packing steps with respect to installation kits in corresponding states of the packing process. The order in which the packing of the installation kit is shown here is a suitable example and is not the only procedure for packing an installation kit according to the invention.

Fig. 7 shows a perspective view of the first packaging 101 prior to packing of installation assemblies and auxiliary equipment in an open condition of the first packaging. When the first packaging 101 is closed it will be a box shaped as rectangular prism of corrugated cardboard with a length extending in the longitudinal direction LP, a width in the width direction WP and a height in the height direction HP. The first packaging 101 has two longitudinal side edges 1012, 1013 extending along the length of the first packaging and spaced apart in the width direction. Similarly, the first packaging has two end edges 1011, 1014 extending along the width of the first packaging 101 and spaced apart in the longitudinal direction. The first packaging 101 is folded from a sheet of corrugated cardboard, provided with folding lines for folding the sheet into and flaps locking in the box shape as shown in Fig. 7.

In Figs 8 to 10b the components of the first of the installation assemblies 5 are packed in the first packaging 101. In this embodiment the first installation assembly comprising the insulating assembly 5 which includes an insulating frame with components comprising a set of side members 52, 53 and

DK 181229 B1 11 two sets of top members 511, 512 and two sets of bottom members 541, 542.

The insulating frame is to be installed as shown in Fig. 3. In Fig. 8 the set of side members 52, 53 are positioned along one longitudinal edge 1012 of the first packaging. As can be seen the length of the first packaging 101 has been selected in accordance to the length of the set of side members 52, 53, which is the longest component in this first set of installation assemblies. Hence the length of the first packaging 101 exceeds the length of the set of side members 52, 53 slightly. The insulating assembly 5 is here accommodated freely in the first packaging and is therefore not packed in sub-packaging nor is it temporarily fixated to the first packaging. The remaining components of the insulating assembly 5, namely the two sets of top members and two set of bottom members, are packed in the first packaging 101 next to each other at one end edge 1014 of first packaging 101 and next to the side members 52, 53 as shown in Fig. 9. Fig. 10a and 10b show detailed views as indicated by Xa and Xb in Fig. 9. Fig. 10a shows the set of side members 52, 53 of the insulating assembly 5 packed together. Fig. 10b shows the two sets of top members 511, 512 and bottom members 541, 542 of the insulating assembly 5 packed together.

Fig. 9 further shows strips of adhesive 1061, 1062 for temporarily fixating components of the first set of installation assemblies and/or the sub- packaging thereof to the first packaging 101. These particular strips of adhesive 1061, 1062 are for temporarily fixating the components of the second installation assembly.

Referring now to Fig. 11 — 12b, where a second installation assembly 6, 6 of the first set of installation assemblies is packed in the first packaging 101. The second installation assembly 6 is here a stabilizing assembly 6, 6’ the components of which comprises two stabilizing rails 6a, 6b. The stabilizing assembly 6 is shorter than the side members 52, 53 of the insulating assembly, and the distance between the strips of adhesive 1061, 1062 in the longitudinal direction in Fig. 9 is selected according to the length of the stabilizing assembly 6. In this embodiment the components of the stabilizing assembly 6 are partially packed in two pieces of sub-packaging 1063, 1064 at both longitudinal ends of

DK 181229 B1 12 the components. The sub-packaging is here two open cardboard boxes. The carboard boxes are open in the sense that at least one of the faces of the cardboard box is open, allowing at least part of the components of the second installation assembly to be accommodated within the cardboard box.

Alternatively, one or both of the open cardboard boxes could be replaced by a suitably formed paper ribbon. The two pieces of sub-packaging are temporarily fixated to the first packaging 101 by the strips of adhesive 1061, 1062 respectively, thereby in turn temporarily fixating the components of the second installation assembly 6 to the first packaging 101. As the components of the second installation assembly are thus fixated to the first packaging 101 in a position where they extend along the longitudinal direction substantially in parallel with the side edges 1012, 1013 of the first packaging, the components of the second installation assembly 6 function as positioning elements with respect to the components of the first installation assembly 5, restricting their movement at least in the width direction WP. In this way less adhesive or glue can be used compared to a packaging wherein each respective installation assembly is temporarily fixated using glue. Figs. 12a and 12b show detailed views of Xlla as indicated in Fig. 11 of two different sub-packaging 1063, 1063’.

In Fig. 12a the sub-packaging 1063 has an inclined upper surface, the upper surface being the surface facing substantially upwards in the height direction.

As the surface is inclined, the sub-packaging will have an upstanding wall portion facing the components of the first installation assembly 5, said upstanding wall portion being having a greater height than the opposite wall of the sub-packaging 1063. The upstanding wall can aid in positioning the components of the first installation assembly 5 and in keeping them in place.

Having an inclined surface reduces the amount of the material needed and allows for a snug fit to the components of the second installation assembly, while providing a tall upstanding wall. In Fig. 12b an alternative sub-packaging 1063' without an inclined upper surface is shown, but which also provides an upstanding wall facing the components of the first installation assembly.

Fig. 11 further shows a strip of adhesive 1981 extending in the longitudinal direction at the side edge 1013 opposite the first installation

DK 181229 B1 13 assembly 5. This adhesive strip 1981 is for temporarily fixating a gutter element 98, an auxiliary equipment, to the first packaging 101, which is shown in Fig. 13. The gutter element 8 has a length in the longitudinal direction, which is shorter than the side members 52, 53 of the insulating assembly 5, which side members are the longest component among the components of the first set of installation assemblies. In order to achieve this length of the gutter element, the gutter element can be provided in two parts, or be telescopic.

In Fig. 13 a further strip of adhesive 1041 is provided near the corner defined by the side edge 1013 and the end edge 1011, next to the gutter element 98. The strip of adhesive 1041 is for temporarily fixating a cardboard box 104 to the first packaging 101 as shown in Fig. 14. The cardboard box 104 is a sub-packaging entirely containing the third installation assembly, which in this case is support assembly 4 the components of which includes four mounting brackets. In Fig. 14 the cardboard box 104 is located in abutment with one of the pieces of sub-packaging 1064 in which the components of the second installation assembly 6 is partially packed. Also shown in Fig. 14 is a strip of adhesive 1071 for temporarily fixating a sub-packaging 107, 107° of the fourth installation assembly to the first packaging 101. The strip of adhesive 1071 is located near one end edge 1011 of the first packaging next to the side members of the insulating assembly 5. The fourth installation assembly is in this embodiment a cover assembly 7, the components of which includes receiver brackets and preferably also a demount tool. As shown in Fig. 15 and 16a the cover assembly 7 is entirely packed in a sub-packaging 107, 107', which is a cardboard box. The cardboard box 107, 107' is temporarily fixated (to the first packaging 101 by strip of adhesive glue 1071. The cardboard box 107, 107' is in this embodiment in abutment with side members 52, 53 of the installation assembly 5, whereby it functions as a positioning element for the side members 52, 53 in the width direction. Hence, the side members 52, 53 are kept in place in the packed installation kit 1, even though they are accommodated freely in the first packaging 101.

Fig. 16a and Fig. 16b shows the detailed view indicated by XVla in Fig. 15, each showing alternative embodiments of the cardboard box 107, 107’.

DK 181229 B1 14

In Fig. 17 a vapour barrier collar 97 is packed in the packaging 101, the vapour collar being an auxiliary equipment. The vapour barrier collar 97 is here packed in a plastic bag 197 and located at a corner of the first packaging 101 between one of the pieces of sub-packaging 1063 accommodating the components of the second installation assembly, and the side edge 1011.

In Fig. 18 the fifth installation assembly 8 is packed in the first packaging 101. The fifth installation assembly is here a cover assembly, the components of which includes a cover plate 8. The length of the cover plate is shorter than the length of the side members 52, 53 of the first installation assembly 5 and is substantially the same length as the stabilizing assembly 6.

The cover assembly 8 is packed in a sub-packaging which is here a paper wrapping enveloping the cover plate 8. The cover plate 8 enveloped in paper wrapping is positioned on top of the pieces of sub-packaging 1063 and 1064 which accommodates the components of the stabilizing assembly. In this way it may be at least partly kept in place between the vapour barrier collar 97 and the two sets of top and bottom members of the insulating assembly 5, as well as the cardboard box 104. In practice, the fourth and fifth installation assemblies constitute sub-assemblies of a common installation assembly which serves to cover the gap between the two window units 11, 12 as shown in Figs. 6.

In Figs 19 to 21 further auxiliary equipment is packed in the first packaging 101, namely a tape roll 96a provided on top of the fourth installation assembly 7, an underroof collar 96 which is packed in a plastic bag 196 and an installation manual 99.

Fig. 21 may thus be a final condition of the packing of the installation kit 1. In this condition only the second, third and fourth installation assemblies 4, 6, 7 and the gutter element 98 are temporarily fixated to the first packaging 101 by strips of adhesive, while the remaining components of the first set of installation assemblies are accommodated freely in the first packaging 101.

Some of the remaining components, namely the first installation assembly 5, is held in place by some of the components which are temporarily fixed, reducing the amount of adhesive in the first packaging 101. As can be seen Figs. 7 to

DK 181229 B1 15 21, the amount of adhesive used in the packaging is comparatively low relative to the amount of packaging. Keeping the amount of adhesive low, can increase the recycling value of the packaging, as cardboard recycling restricts the amount of “unwanted material”, such as adhesive, in the cardboard material.

Fig. 22 is a plan view of auxiliary equipment comprising an underroof collar 96, in which the sub-packaging of the underroof collar which is a plastic bag 196, which is intended for collection of waste, in particular plastic waste during unpacking of the installation kit and installation the skylight window system 1. The plastic bag 196 is provided with a label 1960 with a recycling logo 1965. The plastic bag 196 with any accommodated plastic waste may then be put into a recycling container dedicated to plastic.

Fig. 23 shows an alternative recycling logo 1965.
