Description

In the registration procedure, the Industrial Property Office does not determine whether the subject of the utility model meets the conditions of eligibility for protection according to § 1 of Act. No. 478/1992 Coll.

A carton assembly containing a carton containing a sunroof and packaging components to protect and hold the sunroof components

Field of technology

This technical solution relates to a packaged sunroof, where the sunroof is placed in a cardboard box and when packaging components are arranged inside the cardboard box to protect and hold the sunroof components.

Current state of the art

When installing skylights in the roof, it is necessary to ensure that both the skylight itself and the connection between the skylight and the roof structure are properly protected against the weather. This is ensured by the use of roofing and sheeting that cover the skylight, or joint. Covering elements and sheeting are usually made of sheet metal, which combines the advantages of light weight and high weather resistance, but which is susceptible to damage caused by deformation and scratching. The flashing elements are usually supplied in a separate package, but at least some of the covering elements are usually pre-attached to the sunroof. To protect these and other sensitive elements such as the sunroof glazing, blocks of Styrofoam or similar shock-absorbing material are placed inside the cardboard box. These blocks can prevent the cardboard box from warping, thereby preventing excessive loading of the sunroof and/or keeping the sunroof components in their intended position inside the box. Other components can be stored in boxes or plastic bags or attached to the cardboard box with glue or adhesive. One example of a wrapped sunroof where these principles are used is known from EP 2748071 B1.

Although this method of packaging has proven itself very well, there is an increasing demand to supply products that are more environmentally friendly.

The essence of the technical solution

In view of these facts, it is an object of a utility model to provide a packaged sunroof that has a smaller climate footprint while maintaining good protection of the sunroof during shipping.

This and other objectives are achieved by using a packaged sunroof of the type mentioned in the introduction, which is additionally characterized by the fact that all components of the package are made of 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 cheap, light, and can be soft enough to prevent chafing of other sunroof components during handling and shipping when packaged. However, the use of EPS and other polymers requires that the packaging material must be separated into different fractions for recycling. In contrast, paper-based packaging components belong to the same fraction as the cardboard box, which greatly increases the likelihood that the packaging material will be recycled instead of just being disposed of as combustible waste, and reduces the risk of contamination of the recycled material by other materials.

Some paper-based materials may have worse properties than EPS and other polymers as far as it goes

- 1 CZ 37830 U1 for abrasion, but this can be compensated for by placing a paper-based slip film between the packaging component and potentially sensitive components of the sunroof, such as the glazing or painted surface of the sash frame. Likewise, smearing must be prevented, either by testing the material chosen for the packaging components or by using a slip film.

Another potential advantage of using paper-based packaging components is that they can be biodegradable. Lightweight packaging elements such as plastic packaging, foil and EPS are easily caught by the wind when installing a skylight on the roof of a building and can easily end up in nature or other places where the installation company cannot collect them. While it is obviously not intended to leave packaging material behind, the paper-based packaging component does not cause much harm as it is essentially biodegradable.

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

In one embodiment, using blocks of paper-based cushioning material, the cardboard box is rectangular in shape with two main sides and four minor sides extending between the two main sides, and the cushioning material blocks are arranged on the four minor sides. This can be advantageous, for example, for packages containing skylights with glass panes, where there is a high risk of falling or rough handling due to the weight and size of the packaged product. Blocks of damping material are placed between the cardboard box and the product, reducing the potential impact to the sunroof. Blocks of cushioning material must have both strength and flexibility or deformability to provide optimal protection. For a wrapped sunroof, flexibility or deformability is especially important in impacts on the sides of the sunroof, while strength is especially important in the corners, where the impact energy is concentrated on a smaller area of the sunroof. In addition, the fact that the roof window frame usually has joints in the corners and that the corners of the roofing are very sensitive places high demands on the shock-absorbing material used in the corners of such a wrapped product.

In one embodiment, at least one block of damping material is placed between the sunroof components. Such a block may serve to hold the components in their intended position within the carton and/or to prevent or limit contact between the components, thereby, for example, preventing one component from being damaged by another, such as being scratched. Such a block can also prevent the deformation of the cardboard box as described above.

In one embodiment, at least one block of damping material is placed on top of the sunroof component. As one example, a block can be placed on top of the sunroof glazing to maintain a distance between the carton and the glazing, potentially preventing both scratching of the glazing and loads acting directly on the glazing. Another example would be a block of cushioning material placed on the handle of the sunroof to prevent or at least limit its movement during handling and transport. As another example, a block is placed on a component whose height is less than the distance between the main sides of the carton, thereby preventing or limiting movement of the component and possibly even causing the component to be pressed against the main side of the package.

In one embodiment, one or more blocks of paper-based damping material contain, or are entirely made of, honeycomb material. Honeycomb materials provide

- 2 CZ 37830 U1 combination of strength and deformability, which makes them particularly suitable for use between heavy products and the cardboard box and/or to prevent deformation of the cardboard box.

Honeycomb materials consist of a series of hollow cells that have a hexagonal shape and are columnar, bounded by thin walls extending in the direction of the height of the material. The size of the cells can vary, usually between 8 mm and 30 mm, and there can be a cover layer on one or both sides. The 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 arranged one above the other and can be connected by an intermediate layer, which is usually a sheet of paper or cardboard. Cell size may vary between layers. In one embodiment, the cells of one layer have a diameter of 10 mm and the cells of the second layer have a diameter of 26 mm.

Each covering layer and/or intermediate layer is usually formed by a sheet of paper or cardboard weighing 100 g/m ² to 250 g/m ² .

A layer of honeycomb material usually has a height that varies between 10 mm and 100 mm, while in multi-layer structures the layers may have different heights.

In one embodiment, a single layer of 14 mm cell size and 20 mm high honeycomb material is on both sides of the cover layer, and both the honeycomb structure and the cover layers are made of 140 g/m ² paper. In the second embodiment, one honeycomb layer with a cell size of 22 mm and a height of 40 mm has a cover layer on both sides, and both the honeycomb structure and the cover layers are made of 140 g/m ² paper. The honeycomb materials of these two embodiments have damping properties that are comparable to those of EPS, as will be further explained with reference to the drawing. In the third embodiment, one honeycomb layer with a cell size of 14 mm and a height of 40 mm has a cover layer on both sides, and both the honeycomb material and the cover layers are made of 120 g/m ² paper. This material is expected to have properties comparable to the second design, as the smaller cells will make the structure stronger, while using thinner paper will make the structure weaker. For purposes where a softer material is required, such as for packaging smaller and/or light windows, a cell size of 26 mm has been found to give good results, the other dimensions being as described above.

In one embodiment, at least one block of damping material is made of pressed paper, preferably high-volume pressed paper. Pressed paper stock can be formed into virtually any desired shape, but has limited strength. It is therefore particularly suitable for applications where a block of damping material must have a complex shape but will not be subjected to high loads, such as a block of damping material intended to be attached to a window handle and held in place.

In one embodiment, at least one block of damping material is made of multilayer corrugated cardboard, i.e. several layers of corrugated cardboard arranged one above the other and connected to each other with glue or adhesive. This material has many of the same advantages as honeycomb material, although the cushioning properties are usually inferior, 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 of folded corrugated cardboard. This gives a cheap block of material and although the strength is low compared to honeycomb material, the weight to strength ratio can also be comparatively low.

In one embodiment, at least one block of cushioning material is made from a cardboard profile. An example can be a cardboard profile in the form of a cardboard tube, which has been deformed so that its surface is wavy, which ensures flexibility. Wavy shapes arranged so that the force acts parallel to the plane of the cardboard prior to profiling are generally considered advantageous.

- 3 CZ 37830 U1

Paperboard profiles, as well as folded corrugated board and pressed paperboard blocks, may be hollow and it is generally believed that voids, depressions and discontinuities in the material may contribute to the desired properties of the cushioning material blocks.

Common to all of the above designs is that the elasticity will be lower than the corresponding EPS block because the paper has relatively low elasticity. Instead, blocks of paper-based damping material rely on inelastic deformation. This is considered acceptable as the package containing the sunroof is rarely subjected to excessive force more than once.

Turning now to the packaging elements in the form of paper bags, these have the potential advantage that the bag can simultaneously contain objects and prevent scratching of sunroof components. A single bag can thus potentially replace both an EPS block and a protective film, potentially reducing either overall material consumption or the number of separate pieces of packaging material that need to be produced and recycled. Reducing the number of separate pieces of packaging material can in turn reduce the risk of them being lost or forgotten.

In one embodiment, a set of components contained in a paper bag includes a mounting bracket. Mounting brackets are usually made of metal and can damage other components if they are loose in the box. This is prevented by providing them in a paper bag.

In one embodiment, the set of components contained in the paper bag includes sealing and/or insulating components. One or more of these components may be provided in a compressed state, thereby reducing its size, in a packaged state and possibly 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 connected to form a paper bag, or the compressed folder(s) including the paper sheet can be placed in a paper bag, possibly together with other uncompressed folders.

In one embodiment, the set of components contained in the paper bag includes electronic components such as wires, photovoltaic elements, sensors, batteries, or a remote control. Electronic components usually contain parts that are easily damaged. By being placed in a paper bag, they are protected from scratches and can stay in place, reducing the risk of them shifting around in the packaging. A shock-absorbing material may be placed inside the bag or on the electronic components before they are placed in the bag. Such shock-absorbing material is preferably also paper-based. For added protection, the electronic component can be placed in its own paper bag before being placed in a paper bag with the other components of the set.

In one embodiment, a set of components housed in a paper bag includes fasteners such as screws, nails, or clips. Fasteners usually have sharp ends that can scratch other components and are easy to lose if loosely laid. This can be avoided by providing them in a paper bag. Fasteners 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 carton during handling and shipping. Interconnection of bags can be created as part of the creation of the bag or by subsequent connection of separate bags. By arranging individual bags in an open cardboard box and connecting them together before closing the box, the bags can be filled independently or in different places. When linked together, they act as a single bag to help keep the components in their intended position inside the cardboard box. It is also possible to attach one or more bags to the cardboard box, thereby achieving similar advantages.

In one embodiment, a first paper bag containing a set of components is placed inside a second paper bag containing a set of components. This can provide additional protection

- 4 CZ 37830 U1 components and/or reduce the risk of sunroof assembly error by preventing access to the set of components inside the first bag until the second bag is opened and emptied.

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

If we now focus on packaging components in the form of boxes, in one embodiment the box may be located along the sunroof frame between the frame and the cardboard box. In this position, the box can help to keep the sunroof in its intended position inside the cardboard box and/or to protect the sunroof in the event of the package being dropped or handled roughly. It can thus replace at least part of the damping material that is traditionally used for this purpose.

In one embodiment, the box is placed on the sunroof glazing between the glazing and the cardboard box, possibly with a slip film between the box and the glazing to prevent the glazing from being scratched. On the side of the glazing that faces the exterior when the sunroof is installed, there is traditionally an impact-absorbing material that protects both the glazing and the cover elements on the sash frame and/or sunroof frame that usually protrude above the glazing surface. Cardboard can reduce or eliminate the need for such shock-absorbing material while preserving other sunroof components.

In one embodiment, the box is attached to a sunroof handle that is adapted to open and close the sunroof. For packaged sunroofs, such grab handles are often arranged in the unfolded state so that the sunroof takes up as little space as possible, and a fixing element in the form of a specially shaped EPS block is used to hold the grab handle in place during handling and transport of the packed sunroof. A box attached to the handle can replace the EPS block and at the same time serves to hold the other components of the sunroof.

In one embodiment, the box is attached to the cardboard box. This gives the box the ability to keep the components in their intended position inside the cardboard box. Alternatively or in addition, the box may be sized and/or shaped to match the internal dimension of the cardboard box so that movement of the box in at least one direction is prevented.

The cardboard can be attached to a cardboard box, to another cardboard or to a sunroof component using glue or adhesive. Alternatively or in addition, mechanical fasteners such as staples or hook and loop fasteners such as Velcro® can be used. Alternatively or additionally, fixing can be achieved by providing the cardboard with a physical structure that allows it to be connected to a product component. One example is the hook-shaped protrusion on the cardboard that connects to the handle of the sunroof.

The above-mentioned boxes can in principle contain any component, but they are advantageously intended especially for sensitive components that can be damaged by contact with other components.

One example of sensitive components are electronic components such as wires, photovoltaics, sensors, batteries or remote controls, which will often have limited strength.

It may also be advantageous to box components that could possibly damage other components. An example of such components are the mounting brackets for connecting the skylight to the roof structure, as they are quite heavy and often have sharp edges or corners. Another example is fasteners such as screws, nails, or staples that have sharp ends and can move around in the carton if not restrained due to their small dimensions.

- 5 CZ 37830 U1

The box may also be used to store one or more components in a folded and/or compressed state. Examples of components that can advantageously be delivered assembled are wires and cables. Examples of components that can advantageously be supplied in a compressed state are sealing tapes and insulating components, thereby reducing their size and packaging state, possibly allowing the use of a smaller cardboard box.

Shock-absorbing material can be placed inside the box.

Nowadays it is considered particularly advantageous to supply the components to be used on the inside of the sunroof in a box or bag placed on the inside of the glazing, for example attached to a ventilation flap or handle. Examples of such components are a remote control to control the skylight after it is installed and a vapor barrier that is used to seal the joint between the skylight and the roof structure, wall or seal on the inside.

Turning now to the packaging components in the form of paper strips, these can be used in one embodiment to hold the components in relation to the cardboard box. Fixing the parts to the cardboard box with paper tape prevents the parts from moving too much in the box, reducing the risk of them getting stuck between other parts and also reducing the possibility of contact with other parts that could lead to scratches. Another potential advantage of holding parts with paper tape is that the need for blocks of shock-absorbing material can be reduced, resulting in a reduction in the amount of material used.

In one embodiment, paper tape is used to secure components in relation to one or more other components, for example by attaching a smaller component, such as a connector or sealing element, to a larger component.

In one embodiment, a set of fasteners such as screws, nails, or staples are held together by paper tape. This not only reduces the risk of losing one or more fasteners. Paper tape can also be used as a retaining element to facilitate the application of fasteners, as will be described with reference to the drawing.

In one embodiment, paper tape is used to secure the components in the folded state. Examples of components that can advantageously be stored in a folded state are wires, cables, sealing tapes, insulating elements, under-roof collars and vapor barriers. These components may be supplied separately or may form part of a larger component, for example a wire connected to a motor unit. In such a case, the wire may be folded and kept in that state only by tape surrounding the folded wire, or the folded wire may be attached to the motor unit with paper tape, thereby keeping it in the folded state.

In one embodiment, paper tape is used to hold the component in a compressed state. This is especially true for sealing and insulating components, which are usually made of compressible and flexible materials. Squeezing them down will reduce their size, possibly allowing a smaller cardboard box to be used. Compression can be achieved by wrapping and tightening paper tape around the components, or an already compressed component can be held in a compressed state by applying paper tape.

In one embodiment, paper tape is used to secure a packaging material, preferably a shock-absorbing material, to the component. As an example, a block of damping material is placed on top of the skylight glazing and is held there by paper tape attached to two opposite sides of the skylight frame and the spanning glazing. As another example, the blocks of damping material arranged around the skylight frame as described above may be attached to each other by means of one or more paper strips. As another example, a component can be attached to a block of damping material with paper tape, preventing inadvertent movement of the component within the carton simply by effectively enlarging it, but it is also possible to attach a block of damping material to the carton, thereby is achieved

- 6 CZ 37830 U1 of indirect attachment of the component to the cardboard box. As another example, a block of damping material can be used to hold a composite component such as a wire or cable in a desired configuration, for example by being placed between sections of the composite component so that sharp bends do not occur.

In one embodiment, paper tape is used to secure the bag or box containing the first component to the second component. An example is a paper bag containing fasteners designed to connect a mounting bracket to a skylight and/or roof structure. As another example, a box containing a remote control to activate the sunroof motor can be attached to the sunroof using paper tape.

In one embodiment, paper tape is used to attach the bag or box containing the first component to the bag or box containing the second component. This may provide the advantage of keeping the smaller bags and boxes together so that they can be more easily placed in a larger carton, and/or allow the sub-components to be packed individually and put together on demand. As an example, the need for insulating components may vary depending on the climate zone in which the sunroof is to be used, and the relevant product for a particular delivery may then be combined with, for example, a carton containing an electronic component before being put into a carton.

Paper tape can be a simple strip of material that is attached to itself, to a box, and/or to another object by means of an adhesive or adhesive, one or more mechanical fasteners, and/or a physical connection, such as by tying a knot. Paper tape can also be paper tape, i.e. a strip of paper provided on one or both sides with glue or an adhesive substance, either in a continuous layer or in the form of local deposits. The adhesive may be a pressure sensitive adhesive. The glue can be a dry glue activated by the action of water.

The paper tape may be provided with local or continuous reinforcements, for example in the form of fibers integrated into the paper or other material applied to the surface of the tape.

Although in the above embodiments, component sets have been described as sets containing components of a certain type made of the same or similar materials, it should be understood that a component set may contain components of different types. Examples include mounting brackets and fasteners intended to be attached to a skylight and/or roof structure that may be provided as a set of components. As another example, the set of components includes insulating components and sealing components to be arranged in parallel along the side of the skylight.

Turning now to packaging components in the form of retaining elements made of folded cardboard, such retaining element may be a vent flap retaining element in one embodiment.

The ventilation flap usually forms part of a roof window, which further comprises a window sash frame carrying the glazing, a window frame, a set of hinges allowing the window sash frame to swing or rotate relative to the frame, and a locking assembly for locking the window sash frame relative to the frame, the locking assembly being operable by movement of the ventilation flap , while in the first and second positions the frame of the window sash is locked relative to the frame and in the third position of the ventilation flap the frame of the window sash is movable relative to the frame. Such a window is usually hung in the middle, and the ventilation flap is located on the upper member of the frame of the window sash, which, when installed, is intended for the upper part of the skylight. The vent flap may be connected to the casement frame or skylight frame by one or more hinges and may be an elongated member that runs along the casement frame member or frame parallel thereto and typically runs substantially the entire width or height of the skylight. A handle can be placed on the ventilation flap for easy operation. If the vent flap is an elongated element, then the handrail may take the form of a rail or rod that runs parallel to the flap and is substantially the same length as the vent flap.

- 7 CZ 37830 U1

In one embodiment, a retaining element of the ventilation flap is located between the ventilation flap and the frame of the window sash or the frame of the sunroof. Skylights are often supplied with the vent flap in a disconnected state, where it is folded away from the frame and/or the sash window frame of the skylight towards the glass to take up less space and thus allow the use of smaller cardboard. A vent retainer located between the vent and the sash frame or sunroof frame holds the vent flap in position and prevents it from moving toward the sash frame or frame during handling and shipping of the packaged sunroof.

In one embodiment, the retaining element of the ventilation flap is located between the ventilation flap and the glass of the sunroof. Such a vent flap retainer prevents the vent flap from moving further toward the glass than intended in the disengaged state, thereby, for example, preventing it from hitting the glazing and potentially damaging it during handling and shipping of the wrapped sunroof.

One retaining element of the ventilation flap can extend from the glazing to the box.

In one embodiment, the vent flap retaining member is located between the vent flap and the cardboard box. This also contributes to keeping the ventilation flap in the intended position during handling and transport of the packed sunroof.

In one embodiment, the sunroof has a handle on the vent flap, and the vent flap retainer is attached to the handle. This arrangement of the holding element of the ventilation flap is especially advantageous in embodiments where the holding element of the ventilation flap is intended to be placed between the ventilation flap and the glazing and/or between the ventilation flap and the cardboard box.

It is also or alternatively possible to attach objects to the retaining element of the ventilation flap, for example by means of glue, adhesive tape, paper tape or paper ribbon. Small items, such as fasteners, can be placed in a paper bag that is attached to the retaining element of the ventilation flap. The screws can also be attached to the retaining element of the ventilation flap by simply screwing into it.

The attachment of the retaining element of the ventilation flap can be achieved by providing a physical structure enabling it to be connected to the handle, for example one or more hook-shaped protrusions. These can be created by bending the material of the retaining element of the ventilation flap.

The retaining element of the ventilation flap can be provided with shock-absorbing material. Such shock-absorbing material is preferably also made of a paper-based material.

Common to all embodiments is that the individual components of the package can for example be made of a material selected from the group consisting of: pressed pulp, folded cardboard, folded corrugated cardboard, multi-layer corrugated cardboard, cardboard profile and honeycomb material, which preferably has a cell size of 22 mm and is made of 140 g/m ² paper and has a height of 20 mm to 40 mm.

Pressed pulp, folded paperboard, or folded corrugated paperboard are considered advantageous for applications where the strength requirement is limited. Molded pulp can be shaped into virtually any desired shape, making it advantageous for applications where the packaging component must have a complex three-dimensional shape, but molded pulp articles generally have large dimensional tolerances. In contrast, folded paperboard and folded corrugated paperboard may have less complex shapes, but may have higher strength and smaller tolerances. In addition, folded paperboard and folded corrugated paperboard can be easily reshaped by folding, unfolding, and possibly refolding into a different configuration.

Multi-layer corrugated cardboard, cardboard profile and honeycomb material are less flexible as far as it goes

- 8 CZ 37830 U1 in shape, but they are stronger and possibly have higher flexibility.

One packaging component can serve several purposes. In one embodiment, a carton made of folded cardboard or folded corrugated cardboard and containing components for use in mounting or operating the sunroof can also be used as a retaining member for the vent.

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

An example is a vent flap retainer that can be configured to serve a secondary purpose after being removed from the vent flap or handle. One example of such a secondary purpose is that the vent retainer is configured to be attached to a corner of the sunroof sash window frame when removed from the vent. The sash window frame of the skylight is often dismantled before the window frame is installed in the opening in the roof structure, and the sash frame must then be placed on the floor, for example. In doing so, there is a risk of scratching or smearing, especially in the corners of the window sash frame. Given that essentially the entire frame of the window sash is visible when the roof window is in use, the possibility of protecting it without increasing material consumption is clearly advantageous. The retaining element of the ventilation flap is preferably attached to the corner of the window sash frame before separating the window sash frame from the window frame. The attachment to the corner of the window sash frame can be achieved, for example, by inserting the corner of the window sash frame or its projection into the recess in the retaining element of the ventilation flap or vice versa. If the ventilation flap retaining member is made of folded cardboard or folded corrugated cardboard, it can be folded into two different configurations, one suitable for the ventilation flap retaining member and the other for protecting the corner of the sash frame. For this purpose, the retaining element of the ventilation flaps may have corresponding flaps and recesses which allow it to be retained in one or more folded states.

As another example, a packaging member made from a molded pulp can be reshaped by being compressible or provided with one or more weakened zones to allow a portion of the packaging member to break off.

Other examples are using a paper bag to collect unused packaging components and using cardboard as a temporary tool box.

Information about the intended secondary use of the packaging component, the installation of a sunroof, or items contained in or attached to the packaging component may be printed on the packaging component. Alternatively, a sticker with this information can be affixed to the packaging.

It should be noted that while paper and paperboard are usually made from wood fibers, other plant fibers can be used, including those derived from straw, bamboo, bagasse, esparto, other grasses, hemp, flax, and cotton, including combinations of different fiber types. In Europe, up to 5% of alternative materials such as glue or adhesive are allowed, but a maximum of 3% is recommended.

An example of the implementation of a technical solution

Fig. 1 first shows a cardboard box 3 for storing the product, which is a sunroof, and this box 3 contains a number of different sized components of the sunroof product. In this embodiment, the cardboard box has a rectangular shape with two main sides 31 and four minor sides 33, 34 extending between the two main sides (only one of the main sides and two of the minor sides are visible in this figure). The shorter side 33 is shown here in a partially assembled state. In the assembled state, the side portions 33' extend perpendicular to the main side 31. In this embodiment, the carton is configured to be opened as shown by arrows P. This type of carton is typically used for heavy products such as skylights with glass filling.

It should be noted that the cardboard box 3 shown in Fig. 1 is only an example and that the cardboard box may have a different shape to better suit the shape and dimensions of the skylight.

Likewise, it is to be understood that the same reference numerals will be used throughout the text for elements that have substantially the same function, even if they are not identical.

Giant. 2 and 3 show how the cushioning material blocks 42 to 47 are arranged around and on top of the sunroof 5 before being stored in a cardboard box as in Fig. 1.

The rectangular blocks 42, 43 of cushioning material run along the side frame elements 51 and the upper frame element of the roof window frame 5, and the cardboard insert 61 compensates for irregularities in the shape of the side sides of the roof window. Block 43 of damping material may also represent a component of the sunroof product, for example an upper covering element, or a set of components, for example a set of smaller components arranged within the cavity of the upper covering element.

A block 44 of cushioning material of more complex shape runs along the lower frame member 52 and creates space for a box 62 containing smaller components such as mounting brackets and/or fasteners. These four blocks 42 to 44 of damping material will be arranged on the four smaller sides of the cardboard box 3 in the packed state of the sunroof 5.

The glazing 53 is protected by two oblong blocks 45 of cushioning material, which are placed on the glazing in such a way that, in the wrapped state, they are located between the roof window 5 and the main side 31 of the cardboard box 3. In the event that the roof window is in the wrapped state, these blocks are situated

- 12 CZ 37830 U1 between the main side 31 and the skylight 5. A paper insert (not shown) can be placed between the oblong blocks 45 of damping material and the glazing 53, which protects the glazing from scratches.

In Fig. 3, the glazing is shown as transparent to show the additional blocks 46, 47 of cushioning material located on the handle 54 of the sunroof. These blocks 46, 47 of damping material serve to hold the handle, which they keep in the intended position relative to the glazing 53 and to the cardboard box in the packed state, and can further be used to store smaller components such as cables and/or remote control.

In Fig. 5, another block 48 of damping material can be seen between the handle 54 and the upper frame element 55 of the roof window 5. In Fig. 5, another block 48 of damping material can be seen. This block supports the upper frame part 56 of the skylight window sash frame.

Fig. 5 also shows the cross-sections of blocks 43, 44, 45, 46 and 48 (block 47 was omitted). They all have a uniform structure and are made of either honeycomb material, multi-layer corrugated cardboard or pressed pulp. Item 62, which was described above as a box, was also shown here as a block of cushioning material, which could be the case if the space provided by the box was not needed.

Turning now to Fig. 6, the damping material block 43 which runs along the upper frame portion 55 is made of folded corrugated cardboard and the damping material block 47 is made of pressed paper, both of which have a hollow center.

All of the blocks 41 to 48 of cushioning material are made of paper or paper and form a cellular structure, either in the form of small randomly spaced cells within the pressed paper or as larger evenly spaced cells in a multi-layer corrugated or honeycomb structure.

An example of the use of a honeycomb structure is shown in Fig. 4, where all the blocks 42 to 45 of the cushioning material are made of honeycomb material arranged in such a way that its height direction protrudes away from the skylight 5 so that in the collapsed state it protrudes from the skylight towards the cardboard the box. The blocks 45 of damping material arranged on the glazing 53 are attached to the side panels 61 with paper tapes, it being understood that the paper tape or paper tapes may also be used to attach or connect other blocks of damping material, for example at the corners where the blocks meet 42, 43, 44 of damping material run along the sides and the top and bottom of the sunroof.

Figures 8 to 9 show the effect of using three different types of damping material. One of them is the honeycomb material shown in Fig. 7, which has a height of 40 mm and a cell size of 22 mm and is made of 140 g/m ² paper. The other two correspond to a honeycomb material with a cell diameter of only 14 mm, and expanded polystyrene (EPS), which is the material used today. The data in Fig. 8 shows the force versus time when the sunroof flips out from a position resting on the lower frame member to fall onto the side frame member, and the data in Fig. 9 shows the force versus time when the sunroof drops on the corner of the window frame. In both cases, the force was measured by a force sensor in the support surface on which the sunroof rests after falling.

In Figure 8, graph 91 illustrates the use of EPS as a shock absorbing material, graph 92 illustrates the use of 14 mm cell size honeycomb material, graph 93 illustrates the use of 22 mm cell size honeycomb material, and graph 97 illustrates the use of 26 mm cell size honeycomb material. As can be seen, the graphs showing the use of honeycomb materials are steeper at the beginning than the graph showing the use of EPS. This is due to the fact that the honeycomb materials are permanently deformed, but this is of no particular importance for the protection of the skylight. On the other hand, the maximum force acting on the window frame is of great importance. Using honeycomb material with a cell size of 14 mm, which is the honeycomb material most commonly used for packaging purposes, the maximum strength is approx.

- 13 CZ 37830 U1 50% higher than when using EPS. On the other hand, the 22 mm cell size honeycomb material provides comparable protection in terms of maximum impact force, and for this application, the 26 mm cell size honeycomb material has better damping properties than EPS.

In Figure 9, graph 94a illustrates the use of EPS as an impact absorbing material, graph 95a illustrates the use of 14 mm cell size honeycomb material, graph 96a illustrates the use of 22 mm cell size honeycomb material, and graph 98 illustrates the use of 26 mm cell size honeycomb material. As can be seen, the 14 mm and 22 mm cell size honeycomb materials provide results that are comparable to using EPS, but the 26 mm cell size honeycomb material stands out significantly worse with peak loads approximately 50% higher than EPS. This is due to the fact that when falling on the corner of the window frame, the load is concentrated on a smaller area of the cushioning material, which leads to the complete collapse of some cells of the honeycomb material.

In Fig. 10, graphs 94a, 94b show the force acting on the window frame when the damping material is EPS, graphs 95a, 95b show the use of honeycomb material with a cell size of 14 mm, and graphs 96a, 96b show the use of honeycomb material with a cell size of 22 mm. Graphs a show the data for the first drop, while graphs b show the data for the second drop on the same corner of the window frame. As you can see, graphs and are comparable, the main difference is in the time course. Both honeycomb materials therefore provide protection to the window frame that is comparable to that provided by EPS. However, if the sunroof falls again on the same corner, the deformation of the damping material caused by the first fall means that the damping capacity is significantly reduced. This is true for all three materials, but it is most pronounced for the honeycomb materials, which have lower elasticity than EPS. For both honeycomb materials, the force acting on the window frame in the second fall is approximately 50% higher than for EPS. However, the risk of a wrapped skylight falling twice on the same corner is low and therefore the residual protection provided by the honeycomb material is currently considered acceptable for the benefits obtained.

The experiments, resulting in the data shown in Fig. 8 to 10, led in their summary to the knowledge that the honeycomb material with a cell size of 22 mm provides good and sufficient protection for the roof window of the most commonly used dimensions. It should be noted that the data presented in Figures 8 to 10 are based on data obtained in standardized laboratory tests and that different force profiles may occur when a window falls in a real environment.

We now turn to Figs. 11 to 15 where alternative blocks of cushioning materials based on honeycomb materials are presented.

In Fig. 11, the cushioning material block is in the form of two separate blocks 44', one at each corner, providing protection where it is most needed. Each block consists of two layers of honeycomb material arranged on top of each other. The intermediate layer between the two honeycomb layers will limit the deformation, since the walls of the two honeycomb structures of the two layers are not directly connected. Thus, a double-layer honeycomb may provide advantages with respect to second falls, but since they are rare, the additional costs associated with using such a material may not be acceptable. This applies to all designs with double-layer honeycomb, not just the design shown in Fig. 11. However, because the lower part of the sunroof is often sensitive to impact loads, and because the wrapped sunroof will often be arranged in such a way that it rests against this side, the use of two-layer honeycomb materials in this particular location is currently considered expedient.

In Fig. 12 two blocks 49 of cushioning material are shown, each consisting of small individual blocks 491 attached to a longer support block 492. The small blocks are intended to contact the window frame in the same manner as in Fig. 11 and the support block contributes both to positioning of small blocks, as well as damping properties.

In Fig. 13, the block 49 of damping material is provided with a pre-molded zone 493 allowing the block to be placed on a projection on the window frame or on another component of the roof window product, which

- 14 CZ 37830 U1 contributes to placing the product or product component inside the cardboard box.

Fig. 14 shows a block 44 of cushioning material corresponding to the block in Fig. 7. The overall structure and function is described with reference to Fig. 12, wherein the block 44 has two separate blocks 441 attached to a longer support block 442, both of which are made of honeycomb material. When in use, the separate blocks extend under the lower cover element of the sunroof and are therefore hidden in Fig. 7. Here the individual blocks 441 are 40 mm high and the support block 442 is 19 mm high, but otherwise the materials are the same. Both have a cell size of 10 mm to allow the packed skylights to be stacked.

In the center of the block 44 is a recess 443 in the support block 442 which creates a space for another packaging component such as the box 62 in Fig. 7 and in this embodiment there is a smaller recess 444 which facilitates the removal of the box by creating a space for a human finger .

In Fig. 15, the honeycomb material is cut almost entirely along two lines, leaving only the cover layer on one side to allow the material to be folded to form a three-layer honeycomb block 44. In Fig. 15, the honeycomb material is cut almost entirely along two lines , leaving only the cover layer on one side.

Alternatives to honeycomb materials are shown in Figures 16 to 18.

In Fig. 16, blocks 42 of damping material in the form of corrugated cardboard tubes are arranged along the sides of the window frame, and a block 45 of damping material in the shape of the letter L is arranged on the glazing. In Fig. 16, you can see how cardboard profiles 45 lie on the glazing. , which are deformed into the shape of the letter L. These shapes give the cardboard profiles, in addition to deformability, flexibility and thus good damping properties.

Figures 17 and 18 show different designs of folded corrugated cardboard serving as blocks of damping material. Compared to honeycomb material, their production is simple and cheap, and they are advantageously used in roof window products or their components, which are not highly sensitive to impact force.

It should be noted that skylights that have an all-wood frame, such as the one in Fig. 17, are less sensitive than skylights whose frame has an outer layer of polyurethane or a similar polymer, since polyurethane is usually less flexible than wood. For the same reason, a block of damping material, such as a block of honeycomb material, used in a wooden window frame may be thinner than a corresponding block of damping material used in a polyurethane frame.

Turning now to Fig. 18, which corresponds to Fig. 3, a block 44 which runs along the lower frame member 52 provides space for a paper bag 70a containing a set of components. Because the paper bag 70a is securely stored in the block 44, it may conveniently contain a collection of relatively fragile components such as electronic components, eg wires, photovoltaic cells, sensors, batteries, or remote controls. A collection of metal components such as mounting brackets may also be housed in the paper bag 70a, as these components may cause damage to other components if not held in place in the cardboard box.

Turning now to Fig. 19, the cushioning material blocks 43, 45, 46 on the upper frame member 55 shown in Fig. 5 are replaced by paper bags 70b, 70c, 70d. Each of the paper bags 70b through d contains a set of components. The paper bag 70b is arranged to at least partially extend along the outer surface of the upper frame member 55, and may suitably include insulating components and edging components. The paper bag 70b may further include an impact-absorbing paper material, whereby the paper bag 70b may provide some protection to the sunroof. Paper bags similar to paper bag 70b can replace the cushioning material blocks 42 of Fig. 3. They can also replace only a portion of the cushioning material blocks 42. Similarly, the paper bag 70c placed on the window pane may also include a paper shock-absorbing material that

- 15 CZ 37830 U1 provides some protection to the sunroof, similar to block 45. It can be seen that the paper bag 70d is attached to the handle 54 to prevent the paper bag with the sunroof from shifting during transport and handling of the wrapped sunroof. This bag could contain, for example, a vapor barrier to seal the joint between the skylight and the roof structure in which it is installed from the inside.

As mentioned above with reference to Fig. 3, the box 62 is located in the cavity 44a and will be located between the sunroof frame and the carton in the packaged state, preventing it from moving in the carton during handling and shipping. The box 62 is protected by a block 44 of damping material and may suitably contain a set of relatively fragile components, for example electronic components such as wires, cables, photovoltaic elements, sensors, batteries or remote controls. A collection of metal components, such as mounting brackets, could also be housed in the box 62, as these components are preferably safely stored in a carton to prevent damage during handling and shipping of the packaged product with other sunroof product components.

Fig. 20 shows the upper end of the roof window 5, which essentially corresponds to the roof window in Fig. 4. As can be seen, the paper tape 7 is used here to secure the block 45 of damping material relative to the skylight 5 and further to secure the box 63 The box 63 is placed on the glazing 53 and contains a set of components for use in the installation of the roof window, such as the roof collar or covering or sheeting components. If the wrapped skylight according to Fig. 20 is stored in a cardboard box, then the box 63 is located between the glazing 53 and the cardboard box. The box 63 is made of cardboard and has a lid 63a which is longer than the remaining sides of the box 63, which allows the lid 63a to extend over the block 45 and between the sunroof 5 and the block 43 of damping material which runs along the upper element of the sunroof frame. A paper tape 7 secures the lid 63a to the block 45, thereby keeping the box 63 in a relatively fixed relationship to the skylight 5. If necessary, a sliding sheet (not shown) of paper material can be placed between the box 63 and the glazing 53 to prevent the box from scratching the glazing. .

We now refer to Fig. 21, which shows the upper end of the sunroof substantially corresponding to the sunroof in Fig. 4, but viewed from the side which is intended to be the inner side in the assembled state of the sunroof. Instead of blocks 46, 47 of damping material from the embodiment in Fig. 4, a box 64 containing a set of components is placed. The box 64 is attached to the handle 54 and has a dual purpose: firstly to hold the handle 54, to keep it in the intended position relative to the glazing 53 and the cardboard box in a packaged state, secondly to contain the set of components. The box 64 is attached to the handle 54 by the physical structure of the box, namely a recess 641 located across the box, which is adapted to receive the handle 54 and has projections 642 for better attachment. Box 64 in this version is made of corrugated cardboard.

Details of another embodiment of the box 64 are shown in Figs. 22, 23, with Fig. 22 showing the carton in a direction substantially parallel to the handle 54 when mounted as in Fig. 21. In this embodiment, the projections 642 are located on opposite side of recess 641, but their function is the same.

The shape of the recess corresponds to the cross-sectional shape of the roof window handle, as best seen in Fig. 22. In this case, the shape is adapted for use with a VELUX roof window, but other windows may require a different shape of the recess.

The side wall 643 of the carton defining the end of the recess 641 consists of three layers of cardboard, as best seen in Fig. 23, while the portions of the box extending along the recess 641, including the projections 642, consist of only one layer. This provides a combination of relative strength and rigidity that facilitates attachment, detachment, and possibly reattachment of the box 64. As is well known to those skilled in the art, the boxes 64 as shown in Figs. 21-23 are often used to store remote controls, manuals, and the like. items that are not intended for the roof window installation company, but for the end user. Such boxes are usually installed by the fitter during the installation of the roof

- 16 CZ 37830 U1 windows removed and then reattached. At that time, the handle 54 is moved from the delivery position shown in Fig. 21 to a position further away from the window and closer to the sash frame and the window frame, and the box is attached with the opposite side to the glass for easy access to the end user. The design of recesses 641 and projections 642 shown in Figs. 21 to 23 facilitates this reattachment of the box.

Now refer to Figs. 24 to 26 showing details of the blocks 44 of cushioning material which run along the side member of the sunroof lower frame in the folded state and serve to accommodate the box 62 as described above with reference to Fig. 3.

In the embodiment in Fig. 24, the block 44 of damping material is provided with a recess 44b on the opposite sides of the cavity 44a. These recesses 44b allow the assembly company to easily remove the box 62 from the block 44 by inserting a finger into the recess and lifting the side carton.

In Fig. 25, an alternative block 44' of damping material is shown in which two corners of the cavity 44a are chamfered to facilitate insertion and withdrawal of the box 62.

Another alternative block 44'' of damping material is shown in Fig. 26 which has both recesses 44b and chamfered corners.

Returning now to Fig. 4, an example of the paper strips 7 are seen which are used to hold the packaging material components in relation to the sunroof product. The product related to the sunroof is embodied here by the sunroof 5, and the packaging material fixed thereto is the impact-absorbing blocks 45. The blocks 45 of damping material placed on the glazing 53 are attached to the side inserts 61 by means of paper strips 7, whereby the blocks 45 are attached to the skylight 5. The paper strips 7 in this embodiment are the paper strips that adjoin the blocks 45 and the inserts 61. It is necessary note that similar paper tapes may also be used to attach or hold other blocks of damping material, for example at the corners where the blocks 42, 43, 44 running along the side, top and bottom of the sunroof meet. One of the paper strips in Fig. 4 further holds the installation manual between the block 45 and the window pane 53. In this embodiment, the damping blocks 42 to 45 are made of paper and consist of honeycomb structures that provide shock absorption.

In Fig. 27, the lower end of the roof window 5 is shown with the elements of the packaging material 44, 45, 61, which essentially correspond to the roof window in Fig. 3. As in Fig. 4, the block 45 holds with respect to the roof window 5 and to the inserts 61 a paper tape 7. In addition, further paper tapes 7 connect the inserts 61 and the block 44 to each other, keeping them in the positions shown relative to the skylight 5.

Returning now to Fig. 20, the upper end of the sunroof 5 can be seen, which substantially corresponds to the sunroof shown in Fig. 3. As can be seen, paper tape 7 is used here to secure the block 45 of damping material to the sunroof 5 and at the same time to hold the box 63. The paper tape 7 holds the block 45 in the same way as in Fig. 27. The box 63 is placed on the glazing 53 and contains a set of components for use in the installation of the skylight, such as a vapor barrier collar or sheeting components. The box 63 is made of cardboard and has a lid 63a which is longer than the remaining sides of the box 63, which allows the lid 63a to extend over the block 45 and between the skylight 5 and the block 43. Paper tape 7 secures the lid 63a to the block 45, thereby maintains the box 63 in relation to the sunroof 5.

Fig. 28 shows an example of a folded component that is held by paper tape 7, which prevents the cable from unfolding. The composite part is embodied here by the rain sensor cable 68. The paper tape 7 here is a strip of paper or cardboard arranged around the folded cable in the form of a loop.

Fig. 29 shows a paper tape 7 that serves to keep the under-roof collar 66 in

- 17 CZ 37830 U1 of the folded state. Here, the paper bag is equipped with printed information 71 informing, for example, about the purpose of using the under-roof collar. In addition, the tape is provided with a weakening 72 in the form of a perforation to allow the tape to break more easily at this location, which facilitates the deployment of the roof collar in the intended manner.

Figure 30 shows a paper tape 7 which is used to secure a tool 67 for use in mounting the skylight product in relation to the carton 2. In this case, the tool 67 is a torque bit, but other tools can be fixed in the same way.

Giant. 31 and 32 show examples of sets of fasteners 65 each held by a paper ribbon 7. In Fig. 31, the fasteners 65 are three screws and the paper ribbon 7 is a strip of cardboard, and in Fig. 32 the paper ribbon is paper tape. In both cases, the screws are connected with paper tape 7.

The embodiment in Fig. 31 has the advantage that the installer can also use the paper tape 7 as a holding element, as shown in Fig. 33, where one of the screws serves to fix the mounting bracket.

In the embodiment of Fig. 32, fasteners 65 are sandwiched between two pieces of paper tape. Alternatively, a single piece of paper tape connecting the set of fasteners may be attached to a box or other object.

We now turn to Fig. 34. This figure is largely identical to Fig. 3, except that different reference numerals are used. In the following text, we will refer to the numbering shown in Fig. 34.

Fig. 34 first shows a roof window 1 with a central suspension, which consists of a frame 11 and a frame 12 of a window sash carrying glazing 13. A roof window 1 with a central suspension is shown in Fig. 2. The sunroof can be opened and closed and vented to an intermediate position by operating a handle 14 connected to the vent flap 15, which in turn is connected to a locking device (not visible in Fig. 34) configured to lock the sash frame to the frame. However, in the condition shown in Fig. 1, the handle and vent flap are shown disconnected from the locking assembly so that the sunroof takes up less space during storage and transportation. To prevent the disconnected handle bar and the ventilation flap from moving too much during handling and transport, the retaining elements 21, 22 of the ventilation flap are attached to the handle 14.

A set of blocks 41 to 45 of damping material is placed around the frame 11 of the skylight and on the glazing 13. These blocks of damping material are intended to protect the skylight when it is stored in a carton before delivery to the customer and will not be described in detail here.

Now let's go to Fig. 35, which corresponds to the section along the line A-A in Fig. 34, only without the retaining element 21 of the ventilation flap, when the roof window 1 is stored in the cardboard box 3. As can be seen, the retaining element 22 of the ventilation flap hooks on the handle 14 and runs from the inner side 131 of the glazing 13 to the part 31 of the cardboard box, which runs parallel to it. In this way, the vent flap retainer not only holds the handle and the vent flap to which the handle is attached, but also contributes to preventing deformation of the cardboard box, thereby protecting the window itself. In a similar manner, a block 45 of damping material placed on the outer side 132 of the glazing 13 maintains the distance between the glazing and the longitudinally extending portion 32 of the cardboard box.

In Fig. 35, another holding element 23 of the ventilation flap can be seen between the ventilation flap 15 and the upper frame element 111 of the roof window 1, which extends into the ventilation passage 151.

This holding element of the ventilation flap can both hold the ventilation flap and support the upper frame member 121 of the roof window sash frame.

Now let's go to Fig. 36, which corresponds to the detail marked B in Fig. 34, but viewed from the inside of the sunroof 1 and shows the box 24 instead of the retaining element 21 of the ventilation flap

- 18 CZ 37830 U1 from pressed paper. It can be seen here that both the handrail 14 and the ventilation flap 15 are elongated and run parallel to the upper frame member 121 of the sash frame and span substantially the entire width of the skylight. This may not be the case, but the ventilation flap should be able to cover the entire opening of the ventilation passage 151, which in this case is divided into a number of openings by the grid structure 152. In this case, the ventilation flap is located on the sunroof.

As can be seen, the holding elements 22, 23 of the ventilation flaps, which were shown in Fig. 35, are both made of folded cardboard, and the box 24 attached to the handle 14 also serves as the holding element of the ventilation flap. The retaining elements 22, 23 of the ventilation flaps can be made from recycled unbleached cardboard, and so can the box 24, but since the box contains items to be used in the installation or operation of the sunroof, it may be advantageous to make it from white cardboard so that it was possible to warn and ensure that the objects inside were not accidentally thrown away.

The retaining element 22 of the ventilation flap is shown in more detail in Figs. 37-39, with the retaining element in the unfolded state in Fig. 37 and in the collapsed state in Fig. 38, which is also seen in Fig. 36. Cut-out 221 in the shape the bone is configured to secure the window handle 14, with the bend lines 222 running perpendicular to the longest dimension of the cutout. As shown in Figs. 39a to 39c, the vent retainer 22 is attached to the handle 14 by first placing the unfolded or slightly folded vent retainer on top of the handle so that the straight portion 2211 of the cutout runs parallel to the handle. During the subsequent folding of the retaining element 22 of the ventilation flap along the bending line 222, the straight sections 2211 pass over the handle, which is located in the wider end sections 2212 of the cut-out 221. The slight elasticity of the cardboard at the location of the bending line 222, which pushes the retaining element 22 of the ventilation flap back to the unfolded state , now presses the ends of the cutout 221 against the handle 14, as also seen in Fig. 36, and holds it in place.

After unpacking the sunroof, the retaining element 22 of the ventilation flap is no longer needed and can be removed. At the same time, it is often necessary to remove the skylight sash to facilitate the installation of the frame into the roof structure, and the retaining element of the ventilation flap can then be folded down further and used to protect the sash frame. Another folded vent retainer is shown in Fig. 40 and another folded vent retainer attached to the corner of the sash frame is seen in Fig. 41. As best seen in Fig. 41, the vent retainer 22 remains folded in its original bending line 222 and is further folded along the secondary bending line 223, which is located at the place of the notch 2231 visible in Figs. 37 to 38 and runs parallel to the original bending line 222. The holding element of the ventilation flap is fixed in the folded state by folding the cutouts 224 in the shape V and cut-out 221 now abuts the flared edge 122 of the sunroof sash window frame as shown in Fig. 41. The cut-out 221 is preferably slightly smaller than the flared edge 122 of the window sash frame so that the folded retaining element 22 of the ventilation flap is held on the window frame wings due to friction.

In this embodiment, the V-shaped cutouts 224 are defined by pre-cuts in the material, but it is also possible to use weakened zones that can be broken when using the V-shaped cutouts, or printed lines indicating where the cardboard is cut.

In addition, information 225 about the intended use of the ventilation flap retaining members 22 may be printed on its surface, as shown in Fig. 37 .

In Fig. 42 and 43, two alternatives of the holding elements 22 of the ventilation flaps are shown. In Fig. 42, the ventilation flap retaining member 22 is pre-folded, with the composition shown in Figs. 39a to 39c resulting in a tube-shaped cross-section instead of a U-shape, and in Fig. 43, the ventilation flap retaining member 22 is made of honeycomb material. Both of these retaining elements of the ventilation flaps are stronger and more stable than the retaining element in Figs. 36 to 39, but are not immediately applicable to protect the corners of the sash frame.

In Fig. 44 to 47, another retaining element 23 of the ventilation flap is now shown in more detail, which is

- 19 CZ 37830 U1 located between the ventilation flap 15 and the upper frame member of the sunroof 1 and extends into the ventilation passage 151. Two bending lines 232 separate the two wing parts 233 from the central part 234. The wing parts are configured to be inserted into the ventilation passage 151 as shown in Figs. 46a to 46b, and the middle portion is configured to press against the ventilation flap 15 as shown in Fig. 47.

The shape and size of the additional retaining element 23 of the ventilation flap depends on the construction of the roof window. In particular, the shape of the ventilation passage 151, and therefore the shape and position of the wing parts 233, may therefore have to differ from those shown in Figs. 44 to 47.

An alternative to the vent flap retaining member 23 of Figs. 44 to 47 is shown in Figs. 48 to 50. This vent flap retaining member 23' is folded along the fold lines 232 so that the cut-out 231 in the center takes on a T-shape which abuts the retaining assembly. element 153 connecting the ventilation flap 15 to the locking assembly 154 (visible only in Fig. 50) of the roof window. At the same time, additional holes 236 and cutouts 237, which overlap in the folded state, abut the lattice structure 152 at the entrance to the ventilation passage 151, and the flexibility that the element acquires by folding holds the retaining element 23' of the ventilation flap in place. The additional cut-out 235 allows the vent flap retainer to also be used with an electrically operated window that includes an additional retainer 155 attached to the vent flap as shown in Fig. 50 .

The shape and size of this retaining element 23' of the ventilation flap also depends on the construction of the skylight. In particular, the shape of the openings 236 and cutouts 235, 237 may differ from the illustration, and the additional cutout 235 may not be present in all embodiments.

Instead of removing the material in the openings 236, the flaps of material can be bent back so that they extend along the surface of the lattice structure 152 in the assembled state. This can help to keep the vent retainer 23 in place.

Compared to the embodiment shown in Figs. 44 to 47, the embodiment in Figs. 48 to 50 has been shown to be stronger and more stable in use.

A common feature of the embodiments in Figs. 36 to 42 and 44 to 50 is the use of cardboard or corrugated cardboard. These materials are considered advantageous due to the combination of low cost and high dimensional accuracy, but other paper-based materials can be used. The fold lines 222, 232 may be pre-defined by printed lines, pressed lines or weak zones in the material, for example by the cardboard being partially cut along the intended fold lines.

Turning now to Figures 51a to 51d, these show how the cardboard blank is folded into the box 24 and attached to the skylight handle 14. This box can serve both to store items for use during the installation or operation of the window, and as a retaining element for the ventilation flap.

It corresponds to the cardboard in Fig. 36, only it has a slightly different shape. Giant. 36 is shown from the inside of the sunroof, while Figs. 51c to 51d are shown from the outside of the sunroof.

As best seen in Fig. 36, the box 24 touches the inside of the window 13, but does not extend above the handle in the opposite direction. However, it is possible to enlarge the box so that it can eventually extend up to the cardboard box 3 in the same way as the retaining element 22 of the ventilation flap in Fig. 35. An example of such a larger box 24' is shown in Fig. 52.
