Description

Packed roof window

The present invention relates to a packaged roof window, where the roof window is contained in a cardboard box, and in which the packaging components which are arranged inside the cardboard box, are used to protect and retain roof window components.

Related art

When fitting roof windows to a roof, it is vital to ensure that both the roof window itself and the joint between the roof window and the roof structure are properly weatherproofed. severe weather. This is ensured by using overlaps and flashing, which cover the roof window and the seal respectively. Capping members and flashing members are usually made from sheet metal, which combines the advantages of low weight and high weather resistance, but is susceptible to damage from warping and scratching. Flashing elements are typically supplied in a separate package, but at least some of the capping elements are typically pre-attached to the skylight. In order to protect these and other sensitive components, such as the glass of the roof window, blocks made of expanded polystyrene or made with a similar damping material are arranged inside the cardboard box. These blocks can prevent warping of the cardboard box, thus preventing excessive loads from affecting the roof window, and/or holding the roof window components in their intended positions inside the box. Other components can be held in plastic boxes or bags or attached to the cardboard box with tape or glue. An example of a packaged roof window, in which these principles are used, is known from EP2748071B1.

While this packaging has worked very well, there is an ever-increasing demand for retail products that are more environmentally friendly.

With this background, an object of the invention is to provide a packaged roof window, which has a lower carbon footprint, while maintaining good protection of the roof window during transport.

This object and the others are obtained with a wrapped roof window of the type mentioned in the introduction, which is further characterized in that all the wrapping components are made from paper-based materials.

Blocks of cushioning material were previously made from expanded polystyrene (EPS), while bags and boxes were made from polyethylene (PE) or polypropylene (PP). These materials are inexpensive, lightweight and can be flexible enough not to cause abrasive damage to other roof window components during handling and packaged shipping. The use of EPS and other polymers, however, requires that the packaging material must be separated into different parts for recycling. Paper-based packaging components on the other hand, belong to the same fraction as the cardboard box, which greatly increases the likelihood that the packaging material will be recycled instead of just thrown away as combustible waste. and reduces the risk that the recycled material will be polluted by other materials.

Some paper-based materials may have poorer properties than EPS and other polymers when it comes to abrasion, but this can be compensated by arranging a paper-based slip sheet between the packaging component and potentially sensitive skylight components, such as the glass or painted surface of the sash. Likewise, smudging should be avoided, by testing the material chosen for the packaging components or by using a slip sheet.

Another potential advantage of using packaging components made from a paper-based material is that they can be biologically degradable. Lightweight packing materials, such as plastic wraps, films, and EPS, are easily blown away when installing a roof window on a building roof and can easily end up in the wild or in other places where they cannot be picked up by the installer. While the intention is not to abandon the packaging material, a paper-based packaging component does very little harm given that it is essentially biodegradable.

The packaging components may include one or more components selected from the group consisting of: pads of paper-based cushioning material, paper bags, paper tapes, collapsible boxes and retainers made from of folded cardboard.

In one embodiment using blocks of paper-based cushioning material, the cardboard box has a rectangular configuration having two major sides and four minor sides extending between the two major sides and the blocks of cushioning material are arranged at the four minor sides. This can be, for example, advantageous for packaging containing skylights with glass panes, which present a high risk of falling or being handled in a rough manner due to the weight and size of the packaged product. The cushioning material blocks are arranged between the cardboard box and the product and thus reduce the potential impact on the roof window. In order to provide optimum protection, blocks of cushioning material must exhibit both strength and elasticity or deformability. For a wrapped roof window, elasticity or deformability is of particular importance for impacts along the sides of the roof window, while strength is of particular importance at the corners, where the energy of the impact is concentrated on a smaller area of the roof window. However, the fact that the roof window sash typically has joints at the corners and that the corners of the pane are very sensitive, places high demands on the damping material used at the corners of such packaged product.

In one embodiment, at least one block of damping material is arranged between components of the skylight. Such a block can be used to hold the components in an intended position inside the cardboard box and/or to prevent or reduce contact between the components, for example thus preventing one component from damaging the other, for example example by crossing it out. Such a block can prevent, at the same time, the deformation of the cardboard box, as described above.

In one embodiment, at least one block of damping material is arranged on a component of the skylight. By way of example, a block can be arranged on a pane of a roof window to maintain a distance between the cardboard box and the pane, thus potentially preventing scratching of the pane and application of loads directly to the pane. . As another example, a block of damping material may be fitted to a handle bar of a roof window to prevent it from shifting or at least reduce movement during handling and transportation. Still by way of example, a block can be arranged on a component, which is smaller in height than the distance between the major sides of the cardboard box, thus preventing or reducing the movement of the component and possibly even resulting in the compression of the component against a major side of the packaging.

In one embodiment, one or more blocks of paper-based cushioning material include honeycomb material, optionally made entirely from honeycomb material. Honeycomb materials provide a combination of strength and deformability, which makes them particularly well suited for use between heavy products and the cardboard box, and/or to prevent deformation of the cardboard box. cardboard.

Honeycomb materials comprise a network of hollow cells, which have a hexagon and columnar shape, bounded by thin walls extending in a height direction of the material. The cell size can vary, typically between 8mm and 30mm and a cover layer can be provided on one or both sides. Cell size is measured perpendicular to the height direction from the center of one of the six sides of the hexagon to the center of the opposite side.

Two or more layers of honeycomb material can be laid on top of each other and can be joined by an intermediate layer which is typically a sheet of paper or cardboard. Cell size may vary between layers. In one embodiment, the cells in one layer are 10mm in diameter and the cells in the other layer are 26mm in diameter.

Each covering layer and/or intermediate layer is typically a sheet of paper or cardboard, typically having a weight of 100-250 g/m ² .

A layer of a honeycomb material typically has a height between 10 mm and 100 mm and in multi-layered structures the layers can have different heights.

In one embodiment, a single honeycomb layer having a cell size of 14 mm and a height of 20 mm has overlapping layers on both sides, and both the honeycomb structure and the layers covers are made from paper with a weight of 140 g/m ² . In a second embodiment, a single honeycomb layer having a cell size of 22mm and a height of 40mm has overlapping layers on both sides, and both the honeycomb structure and the covering layers are made from paper having a weight of 140 g/m ² . The honeycomb materials of these two embodiments have damping properties, which are comparable to those of EPS, as will be explained in more detail below with reference to the drawing. In a third embodiment, a single layer of honeycomb having a cell size of 14 mm and a height of 40 mm has covering layers on both sides and both the honeycomb material and the layers covering are made from paper having a weight of 120 g/m ² . This material is expected to have properties comparable to the second embodiment since smaller cells make the structure more robust, while the use of thinner paper makes the structure more fragile. For needs of a softer material, such as for wrapping smaller and/or lightweight windows, a cell size of 26mm has been found to provide good results, other dimensions being as described above.

In one embodiment, at least one block of cushioning material is made from molded paper pulp, preferably loose molded paper pulp. Molded dough can be given almost any desired shape, but it has limited strength. It thus lends itself in particular to applications in which the block of damping material must have a complex shape, but is not subjected to high loads, such as for example a block of damping material configured to be fixed on a window handle bar and hold it in place.

In one embodiment, at least one block of damping material is made from multi-layered corrugated cardboard, i.e. several layers of corrugated cardboard arranged on top of each other and interconnected by a glue or an adhesive. This material has many similar advantages to honeycomb material, although the damping properties are often worse, depending on factors such as the number of layers and the properties of the paper used.

In one embodiment, at least one block of cushioning material is made from folded corrugated cardboard. This provides an inexpensive block of material, and even though the strength is low compared to honeycomb material, the weight to strength ratio can also be relatively low.

In one embodiment, at least one block of damping material is made from a cardboard profile. As an example, the cardboard profile can be a cardboard tube, which has been deformed so that the surface is corrugated, thus providing the elasticity. Corrugated shapes arranged so that the force is applied parallel to the plane of the paperboard prior to profiling are generally considered to be advantageous.

Cardboard profiles as well as folded corrugated board and blocks made from molded pulp can be hollow, and it should generally be understood that hollows, cavities and discontinuities in the material can contribute to providing desired properties to the blocks of damping material.

The fact common to all the embodiments mentioned above is that the elasticity is lower than that of a corresponding block of EPS, since the paper has a relatively low elasticity. Instead, blocks of paper-based damping material rely on inelastic deformation. This is considered acceptable as a package containing a skylight is very rarely exposed to excessive force more than once.

Referring now to packaging components in the form of paper bags, they have the potential advantage that the bag can at the same time retain items and prevent scratching of roof window components. Thus, a bag can potentially replace both an EPS block and a protective film, thus potentially reducing the total material consumption or the number of separate pieces of packaging material to be manufactured and recycled. Reducing the number of separate pieces of packaging material can in turn reduce the risk of losing or forgetting them.

In one embodiment, a set of components contained in a paper bag includes mounting brackets. Mounting brackets are typically made from metal and may damage other components if provided loose in the box. This is avoided by providing them in a paper bag.

In one embodiment, a set of components contained in a paper bag includes sealing and/or insulation components. One or more of these components may be supplied in a compressed state, reducing their size in the packaged state and potentially allowing the use of a smaller cardboard box. Compression can be achieved by wrapping and tightening a sheet of paper around the components. The sides of this sheet of paper can then be interconnected so that a paper bag is formed, or the compressed component(s) comprising the sheet of paper can be arranged in a paper bag, possibly together with other uncompressed components.

In one embodiment, a set of components contained in a paper bag includes electronic components, such as wires, photovoltaic elements, sensors, batteries or remote controls. Electronic components typically include parts that are easily damaged. By supplying them in a paper bag, they are protected against scratches and can be held in place so that the risk of being moved around in the packaging is reduced. A damping material may be provided inside the bag or arranged on the electronic components before they are arranged in the bag. Such damping material is preferably also paper-based. For further protection, an electronic component can be arranged in its own paper bag before being placed in the paper bag with the other components of the assembly.

In one embodiment, a set of components contained in a paper bag includes fasteners, such as screws, nails, or clamps. Fasteners typically have sharp ends, which can scratch other components, and are easily lost if supplied loose. This is avoided by providing them in a paper bag. Fasteners intended for different purposes can be supplied in separate bags.

In one embodiment, two or more paper bags each containing a set of components are interconnected. This can help maintain the intended position of each paper bag inside the cardboard box during handling and shipping. The interconnection of bags can be established as part of the creation of the bag or by successive interconnection of separate bags. By arranging separate bags in an open cardboard box and interconnecting them before closing the box, the bags can be filled independently, possibly at different locations. when interconnected, they will act as a bag, helping to retain the components in an intended position inside the cardboard box. It is also possible to connect one or more bags to the cardboard box, thus obtaining similar advantages.

In one embodiment, a first paper bag containing a set of components is provided inside a second paper bag containing a set of components. This may provide additional component protection and/or may reduce the risk of error in roof window installation by preventing access to the component assembly inside the first bag until the second bag has been opened and emptied.

The paper bag or bags may be closed by folding, by means of mechanical fasteners, such as staples, or by means of glue or adhesive. Also or alternatively, a paper bag can be made completely or partially from a heat-sealable paper, so that the bag can be closed by heating the paper, for example by welding.

Referring now to packaging components in the form of folding boxes, a folding box may, in one embodiment, be arranged along a frame of the skylight between the frame and the cardboard box. In this position, the collapsible box can help to hold the skylight in its intended position inside the cardboard box and/or to protect the skylight in the event that the packaging falls or is roughly handled . It can thus replace at least some of the damping materials, which are traditionally used in this respect.

In one embodiment, a folding box is arranged on the roof window pane between the pane and the cardboard box, possibly with a slip sheet between the folding box and the pane to avoid scratching the pane. Traditionally, damping material is arranged on the side of the pane, which is intended to face the outside, in the mounted state of the roof window, to protect both the pane and the covering elements on the roof window frame and/or sash, which typically protrude above the surface of the glass. The folding box can reduce or eliminate the need for such damping material while retaining, at the same time, the other components of the skylight.

In one embodiment, a collapsible box is attached to a handle bar of the roof window adapted to be used to open and close the roof window. In packaged roof windows such handle bars are often arranged in a disengaged state so that the roof window takes up as little space as possible and a fixing element in the form of a block of EPS formed specially is used to hold the handle bar in place during handling and transportation of the packed roof window. A collapsible box attached to the handle bar can replace the EPS block, while at the same time serving to hold other roof window components.

In one embodiment, a folding box is attached to the cardboard box. This can allow the folding box to retain the components in an intended position inside the cardboard box. Alternatively or additionally, the folding box may have a size and/or shape corresponding to an internal dimension of the cardboard box such that the folding box cannot move in at least one direction.

A folding box can be attached to the cardboard box, another folding box or a component of the skylight by means of glue or adhesive. Alternatively or additionally, mechanical fasteners, such as staples or a hook and loop type fastener, such as Velcro®, may be used. Alternatively or additionally, the attachment may be achieved by providing the folding box with a physical structure enabling it to engage with a component of the product. An example is a hook-shaped protrusion on the folding box that engages a roof window handle bar.

The folding boxes mentioned above can in principle contain any component, but are considered to be particularly advantageous for sensitive components, which can be damaged by contact with other components.

An example of sensitive components is represented by electronic components, such as wires, photovoltaic elements, sensors, batteries or remote controls, which often have limited resistance.

It can also be advantageous to arrange components, which are likely to damage other components, in a folding box. An example of such components are mounting brackets to connect a roof window to a roof structure as they are relatively heavy and often have sharp edges or corners. Another example is represented by fasteners, such as screws, nails or clamps, which have sharp ends and can move around in the cardboard box if they are not restrained due to the small size.

A folding box can also be used to hold one or more components in a folded and/or compressed state. Examples of components, which may be advantageous to distribute in a folded state, are wires and cables. Examples of components, which are advantageous to distribute in a compressed state, are sealing strips and insulating components, thereby reducing their size and packaged state and potentially allowing the use of a smaller cardboard box.

Cushioning material can be provided inside the folding box.

It is considered particularly advantageous to provide the components, which are to be used on the inner side of the roof window, in a collapsible box or bag provided on the inner side of the pane, e.g. a ventilation flap or a handle bar. Examples of these components are a remote control to operate the roof window, once installed, and a vapor barrier, which is used to seal the joint between the roof window and the roof structure, wall or waterproofing on the inner side.

Referring now to packaging components in the form of paper tapes, they may, in one embodiment, be used to retain a component relative to the cardboard box. Securing them to the cardboard box with paper tape prevents the components from moving around too much in the box, reducing their risk of being caught between other components, and the possibility of contact with other components, which can result in scratches, is also reduced. Another potential benefit of retaining components with paper tape is that the need for cushioning material blocks can be reduced, leading to a reduction in the amount of material used.

In one embodiment, a paper tape is used to retain one component from one or more other components, for example, by attaching a smaller component, such as a fastener or sealing member, to a larger large component.

In one embodiment, a set of fasteners, such as screws, nails or clamps, are interconnected by a paper tape. This not only reduces the risk of one or more fasteners getting lost. Paper tape can also be used as a backing to facilitate the use of fasteners, as will be described with reference to the drawing.

In one embodiment, a paper tape is used to retain a component in a folded state. Examples of components, which are advantageously supplied in a folded state, are wires, cables, sealing strips, insulating elements, underlay collars and vapor barriers. Such components may be supplied on their own or form part of a larger component, an example being a wire connected to a motor unit. In this case, the wire can be bent and retained in this state by a tape surrounding the bent wire only, or the bent wire can be fixed to the motor unit by means of a paper tape, thus retaining it to the folded state.

In one embodiment, a paper tape is used to retain a component in a compressed state. This particularly applies to sealing and insulating components, which are typically made from compressible and elastic materials. By compressing them, their size is reduced, potentially allowing the use of a smaller cardboard box. Compression can be achieved by wrapping and tightening paper tape around components, or an already compressed component can be retained in a compressed state by applying paper tape.

In one embodiment, a paper tape is used to secure packaging material, preferably cushioning material, to a component. For example, a block of damping material can be fitted to the roof window glass and held there by paper tape attached to two opposite sides of the roof window frame, covering the glass. As another example, blocks of damping material arranged around the sash of a roof window, as described above, may be secured together by means of one or more paper tapes. As another example, a component can be secured to a pad of cushioning material using paper tape, thus preventing the component from unintentionally moving around in the cardboard box simply by effectively becoming larger. , but it is also possible to fix the block of damping material to the cardboard box, thus obtaining an indirect fixing of the component to the cardboard box. As another example, a block of cushioning material can be used to hold a bent component, such as a wire or cable in a desired configuration, for example by being arranged between sections of the bent component so that sharp creases are avoided.

In one embodiment, a paper tape is used to secure a bag or collapsible box containing a first component to a second component. For example, a paper bag containing fasteners intended to connect a mounting bracket to a roof window and/or roof structure, may be attached to the mounting bracket. As another example, a collapsible box containing a remote control to activate a motor of a roof window, can be fixed on the roof window, by means of a paper tape.

In one embodiment, a paper tape is used to secure a bag or collapsible box containing a first component to a bag or collapsible box containing a second component. This can provide the advantage of holding smaller bags and collapsible boxes together, so that they are more easily positioned within a larger cardboard box, and/or allow sub-components to be individually wrapped and joined to Requirement. By way of example, the need that the insulating components may be different depending on the climatic zone in which a roof window is used, and the product in question for a particular distribution, can then be combined for example with a folding box containing an electronic component before being placed in the cardboard box.

The paper tape can be a simple strip of material, which is attached to itself, to the cardboard box and/or another article by an adhesive or glue, by one or more mechanical fasteners and/or by physical hold, like tying a knot. The paper tape can also be a paper tape, i.e. a paper tape provided with an adhesive or glue on one or both sides, either as a continuous layer or as local deposits. The adhesive may be a pressure sensitive adhesive. The glue may be dry glue activated by exposure to water.

The paper tape can be provided with local or continuous reinforcements, for example in the form of fibers embedded in the paper or an additional material applied to a surface of the tape.

While in the above embodiments the component assemblies have been described as comprising components of a particular type made from the same or similar materials, it should be understood that a component assembly may include components of different types. By way of example, mounting brackets and the fasteners provided to secure them to a roof window and/or roof structure may be provided as a set of components. As another example, insulation components and sealing components to be arranged in parallel with each other along one side of a roof window may be provided as a set of components.

Referring now to packaging components in the form of retainers made from folded cardboard, such a retainer may, in one embodiment, be a vent retainer.

A ventilation flap is typically part of a roof window further comprising a frame carrying a pane, a sash, a set of hinges allowing the frame to swing or rotate relative to the sash, and a latch assembly for locking the frame relative to the chassis, wherein the locking assembly is operable by moving the ventilation flap, wherein when in the first and second positions the frame is locked relative to the chassis, and in a third position the ventilation flap, the frame is movable relative to the frame. Such a window is typically centrally hung and the ventilation flap is positioned at an upper frame member intended to be at the top of the skylight when fitted. The ventilation flap may be connected to a frame or sash of the roof window by means of one or more hinges, and may be an elongated member extending along a member of the frame or sash, parallel with this latter, typically extending substantially the entire width or height of the skylight. A handle can be provided on the ventilation flap to facilitate the operation. If the ventilation flap is an elongated element, the handle may be in the form of a rail or a bar extending parallel to the latter and having substantially the same length as the ventilation flap.

In one embodiment, a ventilation flap retainer is arranged between the ventilation flap and a frame or sash of the skylight. Roof windows are often delivered with the vent louver in a stripped-down state where it has been swung away from the roof window sash and/or frame towards the glass so that it takes up less space, allowing thus the use of a smaller cardboard box. A ventilation flap retainer arranged between the ventilation flap and a frame or sash of the roof window holds the ventilation flap in this position, preventing it from moving towards the frame or sash during handling and transport of the packed roof window.

In one embodiment, a ventilation flap retainer is arranged between the ventilation flap and a pane of the roof window. Such a vent louver retainer prevents a vent louver provided in an unobstructed state, from continuing to move towards the glass than intended, thereby preventing it, for example, from banging on the glass and potentially causing damage during handling and transport of the packed roof window.

A vent damper retainer can extend from the glass to the cardboard box.

In one embodiment, the ventilation flap retainer is arranged between the ventilation flap and the cardboard box. This also helps to keep the ventilation flap in the intended position during handling and transport of the packed roof window.

In an embodiment in which the roof window includes a handle on the vent louver, the vent louver retainer is attached to the handle. This arrangement of the ventilation flap retaining device is particularly advantageous in embodiments where the ventilation flap retaining device is intended to be arranged between the ventilation flap and the window and/or between the ventilation flap and the cardboard box.

It is also, or alternatively, possible to secure articles to a vent flap retainer, for example using glue, adhesive, paper tape or paper tape. Small items such as fasteners can be stored in a paper bag, which is attached to the vent damper retainer. Screws can even be attached to the ventilation flap retainer by simply screwing them into it.

The attachment of the ventilation flap retainer can be achieved by providing it with a physical structure allowing it to engage with the handle, such as one or more hook-shaped projections. These can be formed by bending the material of the vent flap retainer.

Damping material may be provided on the vent damper retainer. Such damping material is preferably also made from a paper-based material.

Common to all embodiments is that each packaging component can be made, for example, from a material selected from the group consisting of: molded paper pulp, folded cardboard, folded corrugated cardboard , multilayer corrugated cardboard, cardboard profile and a honeycomb material, preferably having a cell size of 22 mm and being made from a paper with a weight of 140 g/m ² and having a height of 20 -40mm.

Molded pulp, folded cardboard or folded corrugated cardboard is considered advantageous for applications where the strength requirement is limited. Molded paper pulp can take almost any shape, and is thus advantageous for applications where the packaging component must have a complex three-dimensional shape, but articles made from molded paper pulp are generally characterized with large dimensional tolerances. Folded cardboard and folded corrugated cardboard on the other hand can take less complex shapes, but can have higher strength and lower tolerances. Further, corrugated cardboard and folded corrugated cardboard can easily be reformed by folding, unfolding and possibly folding into another configuration.

Multi-layer corrugated cardboard, cardboard profile and a honeycomb material are less flexible in terms of shape but are more robust and also potentially have greater elasticity.

A packaging component can serve many purposes. In one embodiment, a collapsible box made from folded cardboard or folded corrugated cardboard and containing components for use in installing or operating the skylight may also be used as the device ventilation flap retainer.

In one embodiment, one or more packaging components are configured to serve a secondary purpose after being removed from the skylight.

For example, a vent damper retainer may be configured to serve a secondary purpose after being removed from the vent damper or handle. An example of such a secondary purpose is that the vent louver retainer is configured to attach to a corner of a roof window frame, after being removed from the vent louver. The frame of a roof window is often removed before the window sash is mounted in an opening in a roof structure, and the frame must then be placed, for example on a floor. By doing this, especially the corners of the frame may be scratched or soiled. Since substantially the entire frame can be visible in the state of use of the roof window, the possibility of protecting it without increasing material consumption is clearly advantageous. The ventilation flap retainer is preferably attached to a corner of the frame before detaching the frame from the window sash. Fixing to the corner of the frame can for example be achieved by inserting the corner of the frame or a projection thereon, into a recess in the ventilation flap retainer or vice versa. When the vent damper retainer is made from folded cardboard or folded corrugated cardboard, it can be foldable into two different configurations, one suitable for retaining the vent damper and one suitable for frame corner protection. For this purpose, the ventilation flap retainer may have corresponding flaps and recesses, allowing it to be retained in one or more folded states.

As another example, a packaging component made from molded paper pulp can be reformed by being compressible or having one or more areas of weakness allowing a section of the packaging component to be broken.

Still other examples are using a paper bag to collect packaging components that are no longer in use and using a folding box as a temporary toolbox.

Information regarding an intended secondary use of the packaging component, regarding the installation of the roof window, or regarding items contained in or attached to a packaging component may be printed on the packaging component. Alternatively, a label with such information can be attached to the packaging component.

It should be understood that while paper and board are usually made from wood fibers, other plant fibers including fibers from straw, bamboo, bagasse, esparto, other grasses, hemp, linen and cotton can also be used, including combinations of different fiber types. In Europe, we can accept up to 5% of alternative materials, such as glue or adhesive, but we recommend a maximum of 3%.
