Description

Technical Field

[0001] The invention relates to a window installation system comprising a kit of parts and a roof window having a window frame and a sash. Furthermore, the invention relates to a method for installing a roof window. Background Art

[0002] When installing windows, especially roof windows on sloping roofs, the typical installation process includes, in a first step, installing a fixed window frame to allow easy access to the outside without having to leave the roof surface. During this procedure, mounting brackets and auxiliary equipment, such as under-roofing equipment, are installed, but sometimes the frame opening is also used to climb through it from the outside to the inside, or during this step, the frame opening is used to climb through it from the inside to the outside. In addition, during the installation process, it is necessary to temporarily fit the sash to ensure that the frame forms a suitable rectangle without deflection, which can be observed when closing and opening the sash. Then, the sash is removed again and possible adjustments to the frame position are performed. The procedural steps are repeated until a satisfactory fit has been achieved. It is known that the most sensitive time for a window is the time when the installer puts the sash in and out, and this is the time when damage is most likely to occur. The step of fitting the sash into the frame usually includes engaging the sash hinge parts with the frame hinge parts. Since the sash carrying the window glass is relatively heavy and can be cumbersome and difficult to handle, especially for wide and / or tall windows, the joining process is challenging and typically involves two people. As the installer works around the window, there are several critical points where he / she can damage the frame or part of the sash even if this procedure is performed very carefully: when removing the sash from the frame, when reassembling the sash and window frame, when passing the sash to the outside, when working from the hanging tool inside, when climbing in and out of the roof while wearing shoes, when reaching parts through the frame to the outside, when the roof is dirty and wet, etc.

[0003] Traditionally, experienced installers use cardboard or towels to protect the frame, but this solution can get wet or fly away and does not provide a high standard of protection for the frame.

[0004] After the damage has occurred, people can use repair kits, but there is no final solution to the problem. Therefore, there is a need for a window installation system that includes a set of components to provide enhanced assistance to the installer during the window installation process. Summary of the invention

[0005] Therefore, against this background, it is an object of the present invention to provide a window mounting system which alleviates or even overcomes the above-mentioned disadvantages.

[0006] In a first aspect, this and other objects are achieved by a window mounting system of the type mentioned in the introduction and which is characterized by the features of claim 1 .

[0007] In this way, a protection unit can be provided which substantially prevents direct contact between objects such as window sashes, tools, body parts, etc. and at least the covered inner part of the window frame, thereby protecting the window frame during the window installation process. In addition, the protection unit serves as a support for the window sash before the hinge is engaged to fit the window sash into the window frame, and as a guide during the engagement of the parts of the hinge, thereby assisting the installer during the installation process.

[0008] In the context of the present application, the term "protection" should be understood as the role of guarding, protecting and / or covering to prevent damage to the window frame or window sash. The at least one side member can have a predetermined length of at least 25 cm to protect the side, so as to limit most of the damage that may occur when operating, installing or removing the window frame. The window frame can be unloaded as a set, installed or unloaded in a free state, or can be installed in a fixed window frame. The advantages of the solution for protecting the window frame include, namely: preventing direct contact between the window sash to be installed in the window frame and the inner part of the window frame, more particularly, when the window sash is removed from the frame, when the window sash and the window frame are reassembled, when the window sash is transferred to the outside, when working inside with a hanging tool, when climbing in and out of the roof with shoes, when the components are extended to the outside through the frame, when the roof is dirty and wet, prevent damage to the window frame.

[0009] Although in certain fields of application only a single side protection member is sufficient, it is preferred to form a protection unit by providing a first and a second side protection member which are connected or connectable to the underbody protection member in the use state.

[0010] Additionally or alternatively, the bottom protection member of the protection unit may be configured to cover substantially the entire inner portion of the bottom frame member facing the central opening, such that the predetermined length of the bottom protection member is substantially equal to the inner width of the window. This solution will allow the entire surface of the bottom part of the window to be protected and this will prevent most of the damage that may occur during the window installation process.

[0011] In a currently preferred embodiment, the protection unit is in a U-shaped configuration in use, the U-shaped configuration comprising a bottom protection member and two side protection members of substantially equal length. The U-shaped protection unit can be in close contact with the adjacent sides of the window frame when it is in place on the window frame, thereby providing better protection unit sturdiness and better protection for the window frame, so that the window frame is protected from damage by liquid or dirt that may accidentally fall on the window frame.

[0012] In principle, the material of the kit can be selected depending on whether it is intended to be reused, etc. Preferably, a "soft material" should be selected, which preferably allows any kind of object including the window sash to fall on the window frame without being damaged. The term "soft material" may include expanded polypropylene (EPP), expanded polystyrene (EPS), rubber or any solid material that can allow objects to fall freely due to its porous structure. A "hard material" can also be selected to have a more rigid structure. The term "hard material" can include solid metals such as aluminum, brass, titanium, bronze, iron, steel, copper, brass, silicon bronze, monel and / or metal alloys, or natural materials such as wood or synthetic materials such as plastic. A combination of soft and hard materials can also be selected for the kit.

[0013] In another embodiment, at least one side protection member may be adapted to be folded at a connection line with the bottom protection member such that the at least one side protection member protrudes relative to the plane of the bottom protection member, thereby facilitating easy and compact storage. The connection line may be made by, for example, deforming, tapping or weakening the material along the folding line, or by applying a strip, adhesive, etc. Alternatively, the connection line may be made using a joint that allows the side protection member to be folded such that the side protection member protrudes relative to the plane of the bottom protection member.

[0014] The kit can also be adapted to be stored and reused one or more times. Preferably, the kit will take up minimal space when folded, which can facilitate storage of the kit. In addition, if the kit can be made of durable materials, the kit can be reused several times for protecting the window frame.

[0015] The protective units of the kit can be provided as separate components, but in a currently preferred embodiment the protective unit is a single one-piece unit. The term "single unit" means that the kit is a single piece and that the single piece corresponds to the protective unit. The advantage of using a single unit is that the kit does not have to be installed or unfolded and the kit is already in protective form and ready to be used.

[0016] The bottom protection member and the at least one side protection member may be connected after having been assembled. In the context of the present application, the term "assembly" should be interpreted as assembly techniques including releasable fastening methods such as screws, interlocking fingers, or bonding techniques including adhesive means, glue, fastening strips, tapes, Velcro. One of the advantages of this solution is that the kit can easily be included in the window packaging and can therefore be delivered with the window packaging, thereby protecting the window frame parts when disassembled. Another advantage is that the solution can be easily assembled when needed.

[0017] In another currently preferred embodiment, the bottom protection member comprises a plurality of pieces, preferably with individually adapted profiles. This is particularly advantageous in modular window installation systems, in which a series of pieces with various individual lengths and profiles form part of the window installation system, so that a variety of window sizes can be accommodated.

[0018] According to a second aspect, a method of installing a roof window is provided.

[0019] Other applicable scopes of the present disclosure will become apparent from the detailed description given below. However, it should be understood that although preferred variations of the inventive concept are indicated, the detailed description and specific examples are given by way of illustration only, because various variations and modifications within the scope of the inventive concept will become apparent to those skilled in the art from the detailed description.

[0020] Therefore, it should be understood that the inventive concept is not limited to the specific steps of the described method or the components of the described system, because such methods and systems can be changed. It should also be understood that the terms used herein are only used for the purpose of describing specific embodiments and are not intended to be limiting.

[0041] The inventive concept will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred variations of the inventive concept are shown. However, the inventive concept may be implemented in many different forms, and the inventive concept should not be construed as limited to the variations set forth herein; rather, these variations are provided for thoroughness and completeness, and these variations fully convey the scope of the inventive concept to the skilled person.

[0042] Figures 1 to 3

[0043] First refer to Figure 1 , a roof window 1 is shown having a window frame 2 having a top frame member 300, a bottom frame member 200, and two side frame members 100 defining a central opening. The window will be referred to as a "roof window" and only as a "window" on an equal basis. The present invention is particularly intended for roof windows to be installed in sloping roof surfaces. Directional terms such as "upper", "lower", etc. refer to the positions shown in the accompanying drawings. "Top", "bottom", "side" indicate the position of the window in the installed state and are used for convenience and should not be considered restrictive. However, the present invention is applicable in principle to all types of windows for installation in all types of roofs, including flat roofs and facades.

[0044] Figure 1 A roof window 1 is shown as seen from the side of the roof window, which side faces the inner side of the building structure in which the roof window 1 is installed. When the roof window 1 is in the installed state, the frame 2 is fixed. A sash 3 carrying a window glass 4 is connected to the frame 2 by a set of hinges 5, so that the sash 3 can be pivoted about a substantially central axis relative to the fixed frame 2 between an open position and a closed position. Corresponding to the components of the window frame 2, the sash 3 has a top sash component 600, a bottom sash component 500, and two side sash components 400.

[0045] There is also provided a covering assembly 6 comprising a cladding piece 61, a cover piece 62 and a top box 63. These elements form part of the covering assembly to protect the outer part of the window from weathering.

[0046] The hinge 5 can also be positioned further upwards towards the upper part of the fixed frame 2 and the sash 3. In order to ventilate the sash 3 and to place it in multiple open positions, an operating member 7 is provided at the top sash member 600, so that the locking mechanism 8 also at the top sash member 600 is disengaged from the anti-strike plate (not shown) on the top member 300 of the frame 2 in a manner known per se. Figure 2a and Figure 3 An example of a so-called pivot hinge is shown in and a detailed description of such a pivot hinge exists in, for example, EP1612352A1, WO 85 / 02646, WO 99 / 28581 and EP3486413A1 of the applicant. The present invention is also applicable to so-called telescopic hinges as described in WO2017076416A1 and EP3252255A1 of the applicant.

[0047] exist Figure 2a In the embodiment, the sash 3 has been removed from the frame 2, and in Figure 3 , the sash 3 is shown separately. The sash 3 is usually connected to the frame 2 in the supply state of the window installation system of the invention, because the sash hinge part 53 of each hinge 5 is engaged with the frame hinge part 52 of the corresponding hinge 5 by corresponding engagement means. In the specific example in which the hinge 5 is a pivot hinge, the disengagement is performed by withdrawing the engagement means of the sash hinge part 53 in the form of a slide bar (not shown in detail) from the engagement means of the frame hinge part 52 in the form of a guide (not shown in detail) of the frame hinge part 52.

[0048] By the terms "external" and "inner", mutually opposite sides of components of the roof window 1 in a direction substantially perpendicular to the plane of the window glass 4 are indicated. The terms "external" and "inner" are used to indicate mutually opposite sides of, for example, frame members 100, 200, 300 in a direction substantially parallel to the plane of the window glass 4.

[0049] Each of the frame members 100, 200, 300 has an inner side facing the central opening. The inner side of each frame member 100, 200, 300 includes an outer portion 102, 202 (the outer portion of the top frame member 300 is not visible) that is covered by the sash 3 when the window is in the closed position and is therefore not visible from the interior of the building structure, and Figure 1300 . The inner part 101 of the side member 100 and the inner part 201 of the bottom frame member 200 shown on the right side are visible. When the window is in the closed position, the inner part 101, 201 is not covered by the sash 3. The reference numeral 101 will be used to indicate the inner part of each of the side members 100, because these members are usually mirror images of each other. Therefore, the inner part 101, 201 of each frame member 100, 200, 300 is visible from the inside of the building structure both in the open position and the closed position of the sash. Finally, each of the fixed frame members 100, 200, 300 also has a bottom surface 103, 203, 303, where the bottom surface includes a groove in a manner known per se, which is suitable for accommodating an inner lining forming a transition between the roof window 1 and the inner wall of the building in which the roof window 1 is installed.

[0050] like Figure 2a As shown, the bottom frame member 200 of the window frame 2 defines an interior width wi. In a particular embodiment of the kit and window mounting system according to the present invention, the frame members 300, 200, 100 are stepped to provide a stepped exterior portion, and the interior width wi is the distance between the mutually facing interior portions 101 of the first side frame member and the second side frame member 100, which is substantially uniform over the height of the frame 2. However, other configurations of frames are contemplated, and as will be readily appreciated by those skilled in the art, the various dimensions of the protective unit 10 in the kit, which will be described in further detail below, are relative.

[0051] In the following, reference will also be made to Figure 2b , which shows the lower left corner when viewed from the inside. In the illustrated embodiment, the outer portion 102, 202 of the inner side of each frame member 100, 200, 300 is offset relative to the inner portion 101, 201 to form a space to accommodate the window sash 3 when the window is in the closed position.

[0052] Figures 4a to 4c

[0053] Now refer to Figures 4a to 4c , a first embodiment of a kit for protecting at least a bottom portion of a fixing frame 2 during window installation will be described in further detail.

[0054] Figure 4a A kit of parts for protecting a window frame during installation of the window is shown, the kit comprising: a bottom protection member 11; and at least one side protection member - here two side protection members 12 and 13. In the following, the side protection members 12, 13 will be referred to jointly or individually; the side protection members 12, 13 may be formed in an identical, mirror-inverted manner, but variations are also conceivable.

[0055] The bottom protection member 11 is formed with a predetermined length 1b, and each side protection member 12, 13 is formed with a predetermined length 1s. The side protection members 12, 13 are connected or connectable to the bottom protection member 11, thereby forming a protection unit 10 of the kit of parts of the present invention. The protection unit 10 is adapted to at least partially cover the inner portion 201 of the bottom frame member 200 and the inner portion 101 of at least one of the first side frame member and the second side frame member 100 in the use position in the installed state of the roof window 1, and the protection unit 10 is in a U-shaped configuration in the use state, comprising the bottom protection member 11 and two side protection members 12, 13 of substantially equal length 1s.

[0056] In the illustrated embodiment, the bottom protection member 11 is configured to cover substantially all of the inner portion 201 of the bottom frame member 200 facing the central opening such that the predetermined length lb of the bottom protection member 11 is substantially equal to the inner width wi of the window.

[0057] In an embodiment of the roof window 1 in which the window frame 2 is formed such that the outer portion 202 of the inner side of the bottom frame member 200 is offset relative to the inner portion 201 to form a stepped portion, the bottom protection member 11 comprises: a first portion 115 having a first thickness; a second portion 116 having a second thickness. The second thickness is different from the first thickness to provide a predetermined profile of the bottom protection member 11. The bottom protection member 11 comprises a base portion 110 having a first longitudinal edge 111 and an opposite second longitudinal edge 112, the first longitudinal edge 111 and the second longitudinal edge 112 respectively extending between one end edge 113 and the other end edge 114 and defining a length 1b of the bottom protection member 11. The first portion 115 has a reduced thickness relative to the second portion 116, thereby defining a shoulder 117 extending substantially parallel to the first longitudinal edge 111 and the second longitudinal edge 112 of the bottom protective member 11 and substantially in the middle of the first longitudinal edge 111 and the second longitudinal edge 112 of the bottom protective member 11, and the first portion 115 is positioned adjacent to the first longitudinal edge 111 and is configured to cover the inner portion 201 of the bottom frame member 200, while the second portion 116 is positioned adjacent to the second longitudinal edge 112 and is configured to cover the outer portion 202 of the bottom frame member 200 of the frame 2 of the roof window 1. In this way, the profile of the outer side of the protective unit 10 is adapted to the profile of the inner side of the window frame at the bottom frame member 200. In addition, a recess 110r is formed in the base portion 110 adjacent to the second longitudinal edge 112. This makes it possible to fit the sash with a bottom handle and thus provide a gripping area for the installer.

[0058] Accordingly, each side protection member 12, 13 comprises a base portion 130 having a first longitudinal edge 131 and an opposite second longitudinal edge 132, the first longitudinal edge 131 and the opposite second longitudinal edge 132 respectively extending between one end edge 133 and another end edge 134. As shown, the other end edge 134 of the side protection members 12, 13 has a profile corresponding to that of the bottom protection member 11.

[0059] In the supplied state, the bottom protection member 11 and the side protection members or the side protection members 12 and 13 are configured to be assembled to form a protection unit. This may take place on the construction site. The protection unit 10 may constitute an element of a kit of parts in a window installation system comprising a large number of parts for assisting the installer throughout the installation process. For example, the parts of the protection unit may be suitable for storage and reuse one or more times, for example in a storage container such as a box, a bag, a net, a belt device and reuse one or more times.

[0060] The material or combination of materials of the components of the protection unit may be selected in any suitable manner. A suitable example may be the side protection members 12, 13 and the bottom protection member 11 formed of expanded polypropylene EPP or expanded polystyrene EPS. The incorporation of hard plastics and / or metals is also conceivable.

[0061] Figure 5a to Figure 5f

[0062] Now refer to Figure 5a to Figure 5f , the installation of the roof window 1 by means of the kit of parts forming the protection unit 10 of the first embodiment will be described in further detail.

[0063] The roof window 1 is provided as described above. The protection unit 10 is formed by a kit of parts as described above comprising a bottom protection member 11 and at least one side protection member 12,13.

[0064] First refer to Figure 5a , the window frame 2 is installed in a sloping roof structure (not shown as such). The protection unit 10 is placed to at least partially cover the inner surface of the bottom frame member 200.

[0065] Now refer to Figure 5b , the window sash 3 is placed on the protection unit 10, wherein at least the top window sash member 600 is in contact with the protection unit 10, so that the protection unit 10 supports the window sash 3. Figure 5c In the detail view of FIG. 1 , it is shown how the upper corners of the sash 3 are supported by the protection unit 10. Note that the sash 3 is placed up-side-down and inside-out, that is, ready for subsequent rotation of the sash 3 relative to the window frame 2.

[0066] The placement of the window sash 3 can be carried out either from the inside, i.e. from the room in which the roof window 1 is to be installed, or from the roof, i.e. from the outside. In the case of installing the window sash 3 from the outside, the window sash 3 can be lifted into place by a crane, such as by Figure 5d The crane suction cup 9 in FIG. Figure 5d It further emerges in FIG. 5 how one of the sash hinges 53 engages with the corresponding frame hinge 52 . The engagement takes place by guiding the protection unit 10 through the sash 3 .

[0067] Then, if Figure 5e As shown, the protection unit 10 is removed, and as Figure 5f As shown, the window sash 3 is rotated relative to the window frame 2 to its closed position.

[0068] In a particular embodiment of the protection unit 10, in which a recess 110r is formed in the base portion 110 adjacent the second longitudinal edge 112, and the locking mechanism 8 is positioned to protrude on the sash 3, the step of placing the sash 3 on the protection unit 10 includes placing the locking mechanism 8 at the top sash member 600 in the recess 110r.

[0069] Figure 6

[0070] Now refer to Figure 6 , the second embodiment will be described in further detail. Elements having the same or similar functions as in the first embodiment carry the same reference numerals, to which 2000 is added. Only the differences with respect to the first embodiment will be described in detail.

[0071] In this embodiment, the protection unit is a single integral protection unit 2010, which may be formed as a molded protection unit, such as EPP.

[0072] Figures 7 to 9

[0073] Now refer to Figures 7 to 9 , the third and fourth embodiments will be described in further detail. Elements having the same or similar functions as in the first embodiment carry the same reference numerals, to which 3000 and 4000 are added, respectively. Only the differences with respect to the first embodiment will be described in detail.

[0074] Here, the bottom protection member 3011; 4011 comprises a plurality of pieces 3111a, 3111b, 3111c, 3111d; 4111a, 4111b, 4111c, 4111d, 4111e acting as building bricks, which can be assembled to adapt the length lb of the bottom protection member to a specific width wi of the window frame 2. The pieces can have individually adapted profiles, for example to provide a recess corresponding to the recess 110r of the first embodiment. In this way, a series of pieces with various individual lengths and profiles can form part of a window mounting system, making it possible to accommodate a variety of window sizes.

[0075] Specially turn Figure 8a , it can be seen how one piece 4111a, 4111d of the bottom protection member 4011 is integrated with the associated side protection member 4013, 4012 to form a corner unit. The term "integral" should be understood as not intended to be disassembled, including a unitary construction and a construction of two or more connected parts.

[0076] In the use state, the corner unit can be easily combined with at least one other piece 4111b, 4111c, 4111e connected or connectable to one piece 4111a, 4111d of the bottom protection member 4011.

[0077] Now refer to Fig. 9 The pieces of the bottom protection member 3011 and the connection between the side protection members 3012, 3013 and the bottom protection member are described, wherein the pieces 3111a, 3111b of the bottom protection member are shown to be connected to each other by at least one rod 3119a, 3119b extending in the longitudinal direction of the bottom protection member and received in the associated track 3110a, 3110b in the bottom protection member 3011. In this manner, the rods 3119a and 3199b of the illustrated embodiment act as pins to secure the pieces together in a friction, force-fit engagement. Fig. 9 As indicated, the connection to the side protection members 3012 and 3013 can be made in a corresponding manner, respectively. The pieces 4111a, 4111d of the corner units of the embodiment of the protection unit (4010) can be connected to each other in a similar manner (in this case, there are pins only in one track to interact with the empty track of the other corner unit), or to adjacent intermediate other pieces 4111b, 4111c and / or 4111e.

[0078] Figures 10 to 14

[0079] Now refer to Figures 10 to 14, the fifth and sixth embodiments will be described in further detail. Elements having the same or similar functions as in the first embodiment carry the same reference numerals, with 5000 and 6000 added to them, respectively. Only the differences with respect to the above-described embodiments will be described in detail.

[0080] Here, the pieces 5111a, 5111b, 5111c; 6111c, 6111b, 6111f, 6111g of the bottom protecting member 5011; 6011 are connected to each other by at least one rod 5119a, 5119b extending in the longitudinal direction of the bottom protecting member and received in the associated rails 5110a, 5110b in the bottom protecting member 3011; 5011; 6011, as shown in the third embodiment above.

[0081] However, in the fifth embodiment, the pieces 5111a, 5111b, 5111c of the bottom protective member 5011 are slidably connected to each other by means of rods 5119a, 5119b in associated tracks 5110a, 5110b slidably received in the bottom protective member 5011, so that the length of the bottom protective member 5011 is adjustable. In turn, this means that one and the same protective unit 5010 can be used in a window frame 2 within a certain range of sizes. Therefore, when the bottom protective member 5011 is in a position where all the pieces 5111a, 5111b, 5111c slide together, the predetermined length 1b corresponds to the combined length of the individual pieces 5111a, 5111b, 5111c, and when two or all three of the pieces 5111a, 5111b, 5111c are partially or completely slid out on the rods 5119a, 5119b, the predetermined length 1b extends to match the internal width wi of the window size in question. As Fig.10 As shown, this also means that gaps are formed between adjacent pieces 5111a and 5111b and / or 511b and 5111c, respectively. Although the inner portion 201 and the outer portion 202 of the bottom frame member 200 are thus partially exposed, the thickness of the bottom protection unit 5010 combined with the appropriate maximum slide-out length provides sufficient overall protection for the window frame.
