    Description

    Technical Field



    [0001] The present invention relates to a packed installation kit for use in the installation of a roof window system comprising two window units and configured to be built in side by side in an inclined roof structure such that the roof window system defines a common height and a combined width in the mounted condition, said installation kit comprising a number of installation assemblies, each including one or more components, and optionally auxiliary equipment.

    Background Art



    [0002] 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.

    [0003] Applicant's pending European patent applications with application numbers 21216869, 21216874, 21216881 and 21216882 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.

    [0004] Furthermore, when installing windows in a roof, it is vital to ensure that the window units themselves are securely attached to the roof structure. In the above-mentioned roof window system, one of the installation assemblies includes a support assembly comprising as components two support beams to which the window units are fastened. Since the support beams thus carry a substantial load in the mounted condition of the roof window system, they need to be sturdy and robust. The material of the support beams may in principle be chosen arbitrarily, as long as the material has sufficient strength and wear properties. Typically, a wooden material is chosen, and may include laminated wooden beams such as Glulam beams, Kerto® beams etc. which are dimensionally stable, strong and light-weight. Even though the material chosen is relatively light-weight, the overall dimensions of the support beams render the supply line challenging. As the length of the support beams furthermore depends on the width of the window units and the combined width in the mounted condition, the packed installation kit may weigh up to about 20-30 kg and have a length of about 2-3 m. Typically, items of such magnitude are supplied either as they are, i.e. unprotected, or wrapped in plastic. The former entails a risk of damage and/or smudging of the components, while the latter might sometimes be considered less desirable from an environmental point of view and furthermore offers only a reduced protection during handling. Document EP1710163 A1 discloses a packed installation kit for use in the installation of a roof window system.

    [0005] 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 safely in a more environmentally friendly way.

    Summary of Invention



    [0006] With this background, it is an object of the invention to provide a packed installation kit, which has a small and/or well-designed 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.

    [0007] In a first aspect, these and further objects are achieved with a packed installation kit of the kind mentioned in the introduction, which is furthermore characterised in that the components of a first set of installation assemblies of the installation kit are accommodated in a first packaging, that the components of a second set of installation assemblies of the installation kit comprise two support beams accommodated side-by-side in a second packaging comprising a rectangular telescopic tube packaging having two parts of corrugated cardboard, a first part of the second packaging having a first length extending between an end portion and an opening, and a second part having a second length extending between an end portion and an opening, and the support beams having a length within a pre-defined range, that the total length of the second packaging as defined by the sum of the length of the first part and the length of the second part exceeds the length of the support beams such that an overlap between the second part and the first part is provided in a supply condition of the installation kit within said pre-defined range of lengths of the support beams of the second set of installation assemblies, and that means are provided to reinforce at least one of the end portions, said means being selected from the group comprising provision of a plurality of cardboard layers at the end portion, provision of a shock-absorbing element at the end portion, and provision of an extended flap portion configured to overlap an exterior side of the second packaging.

    [0008] By the provision of a telescopic packaging and two parts with individual lengths chosen to provide a suitable overlap within a range of the length of the two support beams, the number of differently sized blanks to be kept in store is reduced drastically. An increased protection is achieved as compared to no packaging, or to a packaging of plastic material. Furthermore, a cardboard packaging has better performance from a sustainability point of view than plastic, since the cardboard packaging is suitable for easy 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.

    [0009] 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.

    [0010] Based on the recognition that one of the challenges in providing suitable packaging for the support beams resides in preventing the support beams from moving in the longitudinal direction and thereby damaging the end portion(s) in case the packaging tilts or is dropped, reinforcement of the end portion(s) has proven a satisfactory solution. The protection of the end portions of the packaging by means of the reinforcement means entail increased safety against unintentional opening of the end portions.

    [0011] In a presently preferred embodiment, the length of the first part is identical for various lengths of the components within said pre-defined range, the length of the first part being preferably 1400 to 1600 mm, more preferably about 1500 mmm. In this way, the two support beams are enclosed either in full or to a large extent in the first part, for instance of above 50%. The second part closes off the packaging and provides suitable overlap. In a preferred further development of this embodiment, the length of the second part is selected in accordance with the length of the support beams, preferably such that a length is selected for a respective sub-range within said pre-defined range, the length of the second part in a shorter sub-range being preferably 1000 to 1400 mm, more preferably about 1200 mm, and wherein the length of the second part in a longer sub-range is preferably 1400 to 1600, more preferably about 1500 mm. In this way, a single size of the first part combined with a second part of two sizes is able to cover a full range of product sizes in a way which is advantageous from manufacturing, handling, cost and environmental points of view.

    [0012] In a second aspect, a method of forming a packed installation kit of the first aspect is provided.

    [0013] The method comprises the steps of:

    providing at least one blank having such dimensions that it is able to form the second packaging in a folded state,

    providing reinforcement means,

    placing the components in the second packaging, and

    applying the reinforcement means to provide a supply condition of the packed installation kit.



    [0014] In one embodiment, the method comprises the steps of providing two blanks which in a folded state form a first part and a second part, respectively, of the packaging

    placing the components in the first part,

    overlapping the second part with the first part to provide a supply condition of the packed installation kit.



    [0015] The packaging may either be formed before inserting the two support beams constituting the components, or the components are first placed on the blank.

    [0016] In one embodiment, the blank is a first blank which in the folded state forms the first part. Subsequently, the components which are at least partially enclosed by the first part are either positioned on a second blank, which in the folded state forms the second part before folding is carried out, or the second blank is formed to the second part before connecting the second part with the first part and the components.

    [0017] These measures provide for full flexibility in the packaging process.

    [0018] Other presently preferred embodiments and further advantages will be apparent from the subsequent detailed description and drawings.

    Description of Embodiments



    [0020] Referring initially to Fig. 1, an installation kit 100 according to the invention is shown in a partly packed condition. The installation kit 100 is intended for use in the installation of a roof window system 1 as shown in Fig. 5, with two window units 11, 12 to be installed side-by-side in an inclined roof structure 2 using the components of installation assemblies and auxiliary equipment of the packed installation kit 100 according to the innovation. In the configuration shown in Fig. 5, the roof structure comprises 2 a number of rafters and battens of which two rafters 21 on either side of the window units 11, 12 and one batten 22 are indicated. The roof structure 2 may include further and/or alternative parts.

    [0021] The installation kit 1 here comprises a second set of installation assemblies 3, which is a support assembly 3 which has an upper support beam 31 and a lower support beam 32. The two support beams 31, 32 have identical lengths L3, identical heights H3 and identical widths, the sum of their widths being the common width B3. The support beams 31, 32 are shown side-by-side extending along the lengths of one another. A second packaging 103 is shown to accommodate the support beams 31, 32. In the embodiment shown, the second packaging 103 comprises a rectangular telescopic tube packaging which has two parts, a first part 1031 and a second part 1032, both of which are made of corrugated cardboard. The first part 1031 has first length L1, width B1 and height H1. Similarly, the second part 1032 has a second length L2, a width B2 and a height H2. As can be seen the sum of the first length L1 and the second length L2 exceeds the length L3 of the support beams 31, 32. The sum of the lengths L1 and L2, is denoted the total length of the second packaging. The first length L1 in Fig. 1 may for example be about 1500 mm while the second length L2 may be about 1200 mm and the length L3 may be about 1700 mm. The material thickness of the cardboard is about 3 mm, but could vary slightly. The first part 1031 has an opening 10310 at one longitudinal end of the first part 1031, and the opening 10310 has suitable dimensions for accommodating the two support beams 31, 32 lengthwise. An end portion 10316 of the first part 1031 is located opposite to the opening 10310. The end portion 10316 closes off the first part 1031. Similarly, the second part 1032 has an opening 10320 and an end portion 10326, which is seen to close off one longitudinal end of the of the second part 1032. When the support beams 31, 32 are packed and accommodated in the second packaging, the end portions 10316, 10326 may in some orientations of the packed installation kit, carry the load of the support beams 31, 32. As will be described in further detail below, the end portions 10316, 10326 may suitably be reinforced, with several layers of cardboard material, preferably corrugated cardboard, by an additional element such as a honeycomb element and/or by providing an additional folding flap.

    [0022] The support beams 31, 32 are provided with such dimensions and selected from such a material that they are able to provide sufficient strength and withstand wear typical of the conditions within a roof structure. Typically, a wooden material is chosen and may include laminated wooden beams such as Glulam beams, Kerto® beams etc., which are dimensionally stable, strong and light-weight. While the support beams 31, 32 are light-weight in comparison to materials such as steel, the dimensions alone render them cumbersome to handle and pack. Referring again briefly to Fig. 5, it is noted that the support beams 31, 32 extend between rafters 21 on either side of the first and second window units 11, 12.

    [0023] Referring now to Fig. 2 which shows the installation kit of Fig. 1 during packing of the support beams 31, 32 of the support assembly 3 in the second packaging 103. The support beams 31, 32 are accommodated side-by-side in the first part 1031 of the second packaging 103. As can be seen the support beams 31, 32 are enclosed to a large extent in the first part 1031, but a portion thereof protrudes from the opening 10310. In this embodiment about 85 % of the support beams 31, 32 are accommodated in the first part 1031. The protruding portion of the support assembly 3, is seen to be shorter than the second length L2 of the second part 1032. The height H1 and width B1 of the first part 1031 is selected such that, when accounting for the thickness of the corrugated cardboard, a snug fit between the support assembly 3 and the interior surfaces of first part 1031 is provided. The snug fit between the first part 1031 and the support assembly, is preferably snug such that the support assembly 3 does not inadvertently slide in the first part 1031, during handling, but not so snug that it impedes unpacking of the of packed installation kit 1.

    [0024] Referring now to Fig. 3a in which the second part 1032 of the second packaging 103 has been slid on to the support assembly 3 and the first part 1031 of the second packaging in a telescoping manner, to provide a supply condition of the installation kit. In this way the second part 1032 constitutes an outer part of the second packaging 103, and an overlap LO is provided between the first 1031 and second part 1032. As can be seen the length LO of the overlap in this embodiment substantially amounts to the difference between the length L3 and the sum of first L1 and second length L2. The first 1031 and second part 1032 having lengths L1 and L2 as shown in Figs 1 to 3, would provide an overlap LO in the supply condition for a predefined range of lengths L3 of the support beams 31, 32. The predefined range for the length L3 has an upper limit of less than the sum of the first L1 and second length L2, although a suitable overlap may in practice require the length L3 to be less than e.g. 95% of the length of sum of the first L1 and second length L2. In the embodiment of Figs 1 to 3, the length L3 is about 65 % of the sum of the first L1 and second length L2.

    [0025] For a given range of products applicable within the roof window system, the length L3 will typically vary between about 1000 mm and up to 3000 mm. By selecting the lengths L1 and L2 suitably, the first part 1031 may have the same length L1, here 1500 mm, throughout the full range, while the length L2 of the second part 1032 may be provided in two different sizes, one of 1200 mm to cover the lower sub-range and one of 1500 mm to cover the upper sub-range.

    [0026] The height H2 and width B2 of the second part 1032 are selected to be greater than the corresponding height H1 and width B1 of the first part 1031, such that, accounting for the corrugated cardboard thickness of the second part, the second part 1032 can be slid on to the first part 1031 in the telescopic manner. The height H2 and width B2 is preferably further selected such that a snug fit between the interior surfaces of the second part 1032 and the exterior surfaces of the first part 1031 is provided. In this way the first and second parts of the second packaging is kept together in the supply condition.

    [0027] It is presently preferred that the length L1 of the of the first part 1031 is identical for lengths L3 within a pre-defined range, while the length L2 of the second part is selected according in accordance with the length L3, optionally from a few pre-defined lengths L2, such as two pre-defined lengths L2. In the embodiment of Figs 1 to 3 the first length L1 is longer than the second length L2, which slightly improves the carbon footprint of the second packaging, as the first part 1031, has a smaller height H1 and width B1, than the second part 1032, thus reducing the amount of material used in the packaging.

    [0028] The first part 1031 and the second part 1032 may further have fixating means for positioning the first part 1031 relative to the support beams 31, 32 and for positioning the second part 1032 relative to the support beams 31, 32 and/or the first part 1031. In Fig. 2, fixating means in the forms of clamps or staples 10330 are shown.

    [0029] For closing off the end portion 10326, and also the opposite end portion 10316, a tape strip 10331 may be provided.

    [0030] Fig. 3b shows a view of an embodiment of the second packaging 103, in which means are provided to reinforce the end portion 10326. In general, such means may be used individually or in combination. The reinforcement means comprise, non-exhaustively, provision of a plurality of cardboard layers at the end portion, provision of a shock-absorbing element at the end portion, and provision of an extended flap portion configured to overlap an exterior side of the second packaging.

    [0031] In the embodiment shown, the reinforcement means comprise positioning a shock-absorbing element in the form of a honeycomb element 10332 between ends of the support beams 31, 32 (not visible) and the end portion 10326 of the second packaging 103. A counterpart honeycomb element 10332 may be provided at the other end portion 10316.

    [0032] Further reinforcement means comprise the provision of several cardboard layers, in the embodiment shown in Fig. 3b in the form of three end flaps 10326a, 10326b, 10326c that in themselves provide reinforcement. Here, they are supplemented by an extended flap portion 10326d configured to overlap an exterior side of the second packaging 103 once the end portion 10326 has been closed. The other end portion 10316 may be configured in a similar way. There may also be differences between the end portions 10316, 10326, for instance in case one end is designated to be a bottom end during storage.

    [0033] Referring now to Fig. 4, which shows part of another embodiment of a packed installation kit 100 according to the invention. In addition to the second set of installation assemblies 3 packed in the second packaging 103, the packed installation kit 100 can in some embodiments further comprise a first set of installation assemblies 4, 5, 6, 7, 8 packed in a first packaging 101. Fig. 4 shows a set of first installation assemblies packed and accommodated in the first packaging 101, which first packaging further accommodates auxiliary equipment 96, 96a, 97, 98. The first set of installation assemblies 4, 5, 6 7, 8, which are accommodated and packed in the first packaging 101, 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. Elements not visible in Fig. 1 are denoted by a broken lead line to the respective reference numeral, typically because such elements are hidden in sub-packagings.

    [0034] The packed installation kit 100 is in Fig. 4 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 101 will be closed, providing the installation kit in a supply condition. 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 is made of corrugated cardboard, which is sometimes called corrugated fibreboard. 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 mounting brackets 4, receiver brackets 7 and cover plate 8 are packed in sub-packaging of cardboard or paper material, namely cardboard box 104, cardboard box 107 and paper wrapping 108 respectively. The first packaging 101 further accommodates auxiliary equipment, namely underroof collar 96 packed in a plastic bag 196, tape roll 96a, a vapour barrier collar 97 packed in a plastic bag 197, a gutter element 98 and an installation manual (not shown). The plastic bags 196, 197 are intended for collection of waste, in particular plastic waste, during unpacking of the installation kit and installation the skylight window system 1. Further details of the first packaging and the first set of installation assemblies may be found in Applicant's co-pending European patent application filed on the same day as the present application.

    [0035] Referring now to Figs 5 to 8, the interaction between the installation assemblies of the installation kit 100 with the roof window system 1 will be described in more detail. In Figs 5 and 6, the roof window system 1 is shown from the exterior of the building and in Fig. 5 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 a combined width W and a 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 a support assembly 3, mounting brackets 4, an insulating assembly 5 and a stabilizing assembly 6. The upper support beam 31 and lower support beam 32 of the support assembly 3 are installed in the roof structure 2 and the roof window system 1 is fastened to them. The length L3 of the two support beams 31, 32 corresponds substantially to the combined width W of the roof window system 1. The insulating frame assembly 5 is a frame surrounding the roof window system 1 in the mounted position and the length of the side members of the frame slightly exceeds the common height H of the roof window system 1. In Fig. 6, both window units 11, 12 of the roof window system 1 are mounted in the roof structure 2 and auxiliary equipment is being installed. The auxiliary equipment is here an underroof collar 96 which is mounted around the roof window system 1 and a gutter element 98. Figs 7 and 8 show views of the roof window system 1 of Fig. 6 as seen from the interior of the building. Fig. 7 shows the roof window system when the vapour barrier collar 97 is installed after having been unpacked from its sub-packaging 197 which is here a plastic bag. Fig. 8 shows receiver brackets 7 being installed to receive and mount the cover plate 8.

    [0036] The first packaging 101 may be closed and sealed by suitable means including adhesive, tape strips, clamps and/or staples. Closure and sealing of the second packaging 103 is carried out as described in the above. Opening of the packagings 101, 103 is typically carried out by tearing or cutting at suitable positions to expose the contents. It is also conceivable to include opening means in the form of tear strips to provide facilitated opening. If so, it is preferred that the tear strips are of the perforated type, i.e. not involving a thread or wire of plastic or metal material.

    [0037] While the first part 1031 and the second part 1032 of the packaging 103 may be provided in the form presented in Figs 1 to 3b, i.e. folded to form a respective tubular shape, it is also conceivable to use a cardboard blank as a substrate during handling of the support assembly comprising the two support beams 31, 32, following which the cardboard material is folded and closed, thus wrapping the support beams 31, 32.

    [0038] Referring now to Figs 9 and 10 which both show an embodiment of a first part 1031 of the second packaging 103 as a blank, which in a folded state forms the first part 1031 of the second packaging. Fig. 9 is a plan view of the blank. The blank is a sheet of corrugated cardboard which is provided with folding lines and cuts which define portions of the blank. At one longitudinal end of the blank there is four end flaps 10316a, 10316b, 10316c, 10316d, which in the folded condition form sections of the end portion 10316 of the first part. When the blank is folded the end flaps 10316a, 10316b, 10316c, 10316d overlap to close off the end portion 10316 of the first part 1031. The end portion 10316 will be reinforced as it will be formed of four layers of corrugated cardboard. The end flaps 10316a, 10316b, 10316c, 10316d may be fixated to each other by adhesive or glue between some or all the end flaps. In the embodiment shown, there are no flaps at the opposite end of the blank, and hence the first part 1031 folded from the blank will be open at that end, providing the opening 10310. Four folding lines extend longitudinally across the blank, segmenting the blank into a top portion 10311, side portion 10313, base portion 10314, further side portion 10312 and flap portion 10315. The side portions 10312, 10313 have identical widths and the top 10311 and base portions 10314 have identical widths, whereby the first part 1031 in the folded state will have rectangular cross-section. In the folded state of the blank of the first part 1031, the flap portion 10315 will overlap partly with the exterior surface of the top portion 10311, providing overlapping surfaces which may be fixated to each other e.g. by means of an adhesive or glue, or by means of clamps or staples.

    [0039] In general, the amount of adhesive or glue used in the first packaging 101 and the second packaging 103 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 of the packaging.

    [0040] To assist in the folding of the blank the folding lines can comprise a weakening of the corrugated cardboard materials, such as perforations, cuts or the cardboard material having been compressed at the folding line. The blank of the first part 1031 can be folded to form the first part 1031 prior to inserting the components 1031, 1032 of the support assembly 3 therein. Alternatively, the components 1031, 1032 can be placed on the blank of the first part 1031 whereupon the blank is folded around the components to form the first part 1031 as shown in Fig. 10. Here the components of the support assembly 3 are placed side-by-side on the base portion 10314 of the blank of the first part 1031, and subsequently the blank can be folded around the components to form the first part 1031 of the second packaging 103.

    [0041] While Figs 9 and 10 only show a blank to constitute a first blank to form the first part 1031 of the second packaging 103, it is understood that a similar, second blank can be provided for the second part 1032. Such a second blank to form the second part 1032 may be folded around the components of the support assembly 3 which are accommodated in the first part, similarly to the process of Fig. 10, to provide the supply condition of the packed installation kit 100.

    [0042] Alternatively, it is possible to apply some of the principles underlying the present invention independently to a blank having such a length that the packaging to be formed is able accommodate the full length of the components of the support assembly 3. In particular, the means for reinforcing the end portions are applicable. A plurality of end flaps including two, three or four end flaps may be provided at either end of the blank. The use of an overlapping flap portion, corresponding to the flap portion 10315, to cover the full length of such a packaging is conceivable. Fixating means in the forms of clamps or staples may be applied throughout the length of the packaging, partly to strengthen the coherence of the packaging itself, partly to provide additional retention of the components of the second set of installation assemblies in the length direction of the packaging, thus mitigating the effect of possible pressure or impact acting on the end portions in case the support beams move in the longitudinal direction of the second packaging.
