Description

Technical Field

[0001] The present invention relates to a handling and installation assembly for a roof window, which comprises a frame, a sash and a hinge having a sash hinge portion, the sash hinge portion comprising a base plate, a slide rail and a pivot pin, wherein the pivot pin extends vertically from the base plate and the slide rail is connected to the pivot pin and is configured to pivot around the pivot pin. Background Art

[0002] The installation and handling of roof windows can be difficult tasks, sometimes requiring multiple people to perform certain tasks on a single roof window. During handling and installation, problems can arise due to components moving in unforeseen ways. This unforeseen movement can result in damage to the roof window or incorrect installation. To prevent this unforeseen movement, the installer may need to physically hold the components to prevent unnecessary movement. However, holding these components limits the resources available to the installer for handling and installation, which in turn requires additional installers for at least some parts of the installation and handling process. During the installation of such roof windows, the sashes need to be repeatedly handled to enable the frame to be installed in the roof structure and to ensure that the fit between the sashes and the frame is correct. Typically, the roof window, including the sashes and frame, is removed from its supplied state in suitable packaging, and the sashes are then separated from the frame. The sashes then need to be handled and stored separately when the frame is installed in the roof structure. In many cases, the sashes can be attached to the frame, detached from the frame, and then reattached to the frame. When handling the window sash, there is a risk that the rails may swing outwards in an uncontrolled manner beyond the contour of the window sash, with the attendant risk of jamming and deformation, or risk of causing damage to the building part.

[0003] Efforts have previously been made to facilitate installation. For example, EP 1 762 680 A2 discloses a hinge arrangement for facilitating the assembly and installation of a roof window, the hinge arrangement comprising a two-part hinge having a first hinge part with a member for receiving a positioning member. The second hinge part has a positioning member movably mounted on the second hinge part and means for releasably securing the position of the positioning member relative to the second hinge part. This hinge arrangement provides for releasably securing the position of the positioning finger relative to the second hinge part by means of a braking device, thereby enabling the positioning finger to be aligned at an angle. The detent device of the hinge arrangement comprises a U-shaped bracket having two legs spaced apart by a predetermined distance so as to exert a compressive force on the cylindrical portion of the free end of the hinge's pivot pin and on the flat portion of the pivot pin when the positioning finger is in a single position, the two legs being configured to stably hold the positioning finger in said single position. However, the detent device is limited to a single function and, since it forms part of the hinge arrangement itself, must also be kept in place during daily operation of the roof window. Summary of the Invention

[0004] An object of the present invention is to provide an improved handling and installation assembly.

[0005] The objects of the present invention are achieved by a transport and mounting assembly for a roof window of the type mentioned in the introduction, and the transport and mounting assembly is further characterized in that the transport and mounting assembly can be connected to a hinge in a releasable manner, the transport and mounting assembly comprises a first element which can be connected to a pivot pin and a slide rail and is configured to rotate together with the slide rail, the transport and mounting assembly comprises a second element which can be connected to the first element and a base plate, the first element and the second element can engage with each other in a first orientation to temporarily lock the slide rail in the first orientation, and the first element and the second element can engage with each other in at least one other orientation including the second orientation to temporarily lock the slide rail in the second orientation.

[0006] Thus, an assembly is provided that facilitates the transport and installation of a roof window. Furthermore, because the transport and installation assembly can be releasably connected to the hinge, it can be removed after facilitating transport and installation, thereby avoiding the risk of the transport and installation assembly interfering with the operation of the roof window after installation, for example, during opening and / or closing of the roof window. Furthermore, because the transport and installation assembly is separate from the roof window, it does not impose any requirements on the roof window to function correctly, resulting in a flexible assembly that can be used with a variety of roof windows. As a further advantage of the releasable feature, the transport and installation assembly can be reused when installing another roof window.

[0007] In this context, "handling" is to be interpreted as one or more actions performed during the transport of the roof window from the manufacturing site to and on the installation site, and also includes removing and reattaching the sash and frame during the installation process.

[0008] In this context, "installation" should be interpreted as one or more actions performed during the installation of the roof window at the installation site.

[0009] Hinges as described herein are already well known in the field of roof windows. For a more detailed description of such hinges, reference is made to EP 0 165 954 B1, EP 1 612 352 A1, WO 99 / 28581 A1 and EP 3 486 413 A1 in the name of the applicant.

[0010] The releasable connection between the handling and mounting assembly and the hinge can be achieved in a variety of ways. The handling and mounting assembly can be screwed onto the hinge. Preferably, the handling and mounting assembly can be frictionally connected and / or snap-fit ​​connected to the hinge, allowing the handling and mounting assembly to be connected to the hinge by simply pressing the handling and mounting assembly onto the hinge, and to release the handling and mounting assembly from the hinge, if relevant, after the snap-fit ​​connection is released, the handling and mounting assembly can be simply pulled off without the need for tools. The engagement between the first element and the second element can be a frictional engagement, a snap-fit ​​engagement, a magnetic engagement, etc. The magnetic engagement can be achieved, for example, by providing a first element having a permanent magnet and a second element having two or more permanent magnets, wherein the two magnets of the second element are positioned corresponding to a first orientation and a second orientation, wherein when the permanent magnet of the first element is aligned with the magnet of the second element, the permanent magnet of the first element and the magnet of the second element attract each other, thereby temporarily locking the slide rail in the first orientation or the second orientation. In one embodiment, the engagement between the first and second elements that provides temporary locking in the first and second orientations is a positive locking engagement. In this way, a secure lock occurs substantially independent of friction; yet, at the same time, the secure lock is easily releasable by removing the positive lock or by forming at least one of the first and second elements with a resilient member.

[0011] Although only the first and second orientations have been mentioned, the present invention is not limited to two different orientations.The first element and the second element are engageable with each other to temporarily lock the slide rail in the third and / or fourth orientations.

[0012] In an embodiment, the first element comprises one or more protrusions, wherein the second element comprises one or more recesses, wherein the one or more protrusions and the one or more recesses are engageable with each other in a first orientation to temporarily lock the slide rail in the first orientation, and wherein the one or more protrusions and the one or more recesses are engageable with each other in a second orientation to temporarily lock the slide rail in the second orientation. Thus, a simple mechanism for providing engagement between the first element and the second element is achieved. In one embodiment, the first element comprises a plurality of protrusions and the second element comprises a single recess. In another embodiment, the first element comprises one or more protrusions and the second element comprises a plurality of recesses. The one or more protrusions are preferably configured to be rotated into the one or more recesses to engage the one or more recesses by rotating the slide rail, thereby allowing the one or more protrusions to be received within the one or more recesses. The one or more protrusions may be released from the recesses by applying a force to further rotate the rail, the applied force causing the one or more recesses and / or one or more protrusions to elastically deform, thereby allowing the one or more protrusions to rotate out of the one or more recesses.

[0013] In an embodiment, the first element includes an outer portion and an inner portion, wherein one or more protrusions protrude from the outer portion, and wherein the inner portion defines a receiving space for receiving at least a portion of the pivot pin and at least a portion of the slide rail. The inner portion may be formed with a shape that complements the shape of the slide rail and the shape of the pivot pin.

[0014] In an embodiment, the first element comprises a connecting pin extending from the upper portion, and wherein the second element comprises a connecting hole for receiving the connecting pin to connect the first element to the second element. Thus, a simple mechanism for connecting the first element to the second element is achieved.

[0015] In an embodiment, the second element comprises a connecting flange for connecting the second element to the base plate of the hinge. This facilitates connecting the transport and mounting assembly to the sash hinge.

[0016] In an embodiment, the hinge comprises a base pin extending from the base plate, and wherein the second element comprises a snap connector for engaging and connecting the second element to the base pin. In addition to facilitating the connection operation, this also provides a stable form-fit or non-form-fit connection of the handling and installation assembly to the sash hinge.

[0017] In an embodiment, the first orientation is a transport orientation configured to facilitate the transport of the roof window, and wherein the second orientation is an installation orientation configured to facilitate the installation of the roof window, including removing and reattaching the sash in the frame. For example, the transport orientation can be used when transporting the sash of the roof window, including the roof window in a shipping box, packaging or the like. In some cases, the sash is provided separately, in which case it is advantageous to keep the slide rail temporarily locked within the profile of the sash. This also applies to the case where the sash is provided together with the frame, wherein transport includes storing the sash separately before attaching the sash to the frame and possibly removing and subsequently reattaching it to the frame. The installation orientation can be used, for example, when installing the roof window in the roof. In such a case, the transport and installation assembly can keep the slide rail in the desired orientation, thereby freeing up resources for the installer installing the window.

[0018] In an embodiment, the roof window comprises a plurality of hinges, each hinge comprising a sash hinge having a base plate, a slide rail and a pivot pin, and wherein the transport and installation assembly comprises an associated first element and an associated second element for each sash hinge of the plurality of hinges. By providing an assembly for each hinge, installation is even more convenient, since temporary locking on either side of the sash is achieved.

[0019] Other presently preferred embodiments and further advantages will become apparent from the ensuing detailed description and accompanying drawings.

[0037] In the following detailed description, preferred embodiments of the present invention will be described. However, it should be understood that, unless otherwise explicitly stated, features of different embodiments are interchangeable between the embodiments and can be combined in different ways. It should also be noted that, for the sake of clarity, the dimensions of certain components illustrated in the drawings may differ from the corresponding dimensions in actual implementations.

[0038] It should be noted that terms such as "upper", "lower", "left-hand side", "right-hand side", "outer", "inner", "outer", "inner" and the like are relative and refer to the perspective in question.

[0039] First refer to Figure 1 , shows a handling and installation assembly 10 in relation to a hinge 5 according to an embodiment of the present invention. Such hinges 5 are well known and suitable embodiments and functional descriptions are shown and described in EP 0165954B1, EP 1612352 A1, WO 99 / 28581A1 and EP 3486413 A1 of the applicant.

[0040] The hinge 5 forms a fastening to Figure 2 , which corresponds to an installation state installed in a sloping roof structure. The roof window 1 comprises a plurality of elements, including a sash 2, a frame 3 and a pane 4 enclosed in the sash 2. The sash 2 is connected to the frame 3 by means of a set of hinges 5 as described above, which are fastened to the frame 3 and to the side members of the sash 2, respectively, so that the sash 2 can be opened relative to the frame 3 about a hinge axis α, which is substantially parallel to the top and bottom members of the frame 3 and the sash. Figure 1 In FIG, the hinge 5 is shown in a position corresponding to the closed position of the roof window.

[0041] Now also refer to Figure 3 and Figure 4, each hinge 5 includes a sash hinge 20 and a frame hinge 30. The sash hinge 20 includes a base plate 21, a slide rail 22, a pivot pin 23, a base pin 24, an indicator 25 and a guide pin 26. The base plate 21 is formed as a substantially flat plate 21. The pivot pin 23 is connected to the base plate 21 and extends perpendicular to the base plate 21. The slide rail 22 is connected to the pivot pin and is configured to pivot around the pivot pin 23. The slide rail 22 is configured to rotate in a plane parallel to the plane defined by the base plate 21. The base pin 24 extends from the base plate 21. The base pin 24 serves as a stop for the slide rail 22 to rotate in the clockwise direction. The indicator 25 indicates to which side member of the sash 2 that the sash hinge 20 should be connected. In the embodiment shown, the indicator 25 is provided as an L formed in the base plate 21. L indicates that the hinge 20 should be connected to the left-hand member of the window sash 2. It should be understood that the other right-hand hinge in the set of hinges has a similar, mirror-inverted configuration. The frame hinge 30 comprises a base plate 31 in a manner known per se and provided with an arcuate guide 32, into which the rail 22 of the window sash hinge 20 is slidably received when the hinge 5 is mounted. To maintain the window sash 2 in a stable open position relative to the frame 3, a leaf spring 33 projects into the arcuate guide 32 to interact with the rail 22 and the guide pin 26. The frame hinge 30 includes two entry and exit points for the rail 22 and the guide pin 26: a first inlet 34 configured to receive the rail 22 and a second inlet 35 for the guide pin. The rail 22 includes a release pin 27 located near its free end, which is axially displaceable perpendicular to the base plate 21. During installation, the slide rail 22 of the sash hinge 20 is introduced into the arcuate guide 32, and the release pin 27 interacts with the inclined portion 31a of the base plate 31 of the frame hinge 30, so that the release pin 27 moves axially by contacting the inclined portion 31a, thereby engaging with the frame hinge 30. Figure 4 3. The sliding rail 22 extends to the opposite side of the sliding rail 22 compared to the position shown in FIG. In the installed position, during opening of the sash 2 relative to the frame 3, the sliding rail 22 can slide in the arcuate guide 32 until the release pin 27 of the sash hinge 20 is caught in the recess 36 of the frame hinge 30. In order to disconnect the sash 2 from the frame 3, the release pin 27 is manually pushed to the release position of the release pin 27, and then the sliding rail 22 can slide out of the arcuate guide 32.

[0042] Reference Figure 5 and Figure 6, shows a perspective view of a window sash hinge 20 and a transport and installation assembly 10 according to an embodiment of the present invention, which is releasably connected to the window sash hinge 20 to allow the slide rail 22 to assume two or more orientations. The transport and installation assembly 10 includes a first element 11 and a second element 12. The first element 11 is connected to a pivot pin 23 and the slide rail 22 and is configured to rotate together with the slide rail 22. The second element 12 is connected to the first element 11 and the base plate 21. The first element 11 and the second element 12 can engage with each other in a first orientation to temporarily lock the slide rail 22 in the first orientation. The first element 11 and the second element 12 can also engage with each other in a second orientation to temporarily lock the slide rail 22 in the second orientation. In Figure 5 In the position shown in , the first element 11 has been connected to the pivot pin 23, and the second element 12 is shown at the following angle: the second element 12 is first moved towards the first element 11 from which it is moved, and therefore towards the base plate 21 of the sash hinge 20. After contact with the first element 11, the second element 12 is then rotated into engagement with the base pin 24 and the base plate 21 itself, as will be described in further detail below. The first and second elements 11, 12 are now engaged with each other to temporarily lock the slide rail 22 in the first orientation, as shown in FIG. Figure 6 The first position is a transport position that prevents the slide rail 22 from being moved unnecessarily during transport of the roof window. In this first position, the slide rail 22 is held as shown in FIG. Figure 6 (For ease of reference, the structure of the sash 2 and the pane 4 is schematically indicated) within the outline of the side member of the sash 2 indicated.

[0043] Now also refer to Figures 7 to 11 , showing various views of details of the handling and installation assembly 10 according to an embodiment of the present invention. The first element 11 comprises an inner portion 113, an outer portion 114 and a plurality of protrusions, the protrusions being Figure 5In the overview of the embodiment, it is indicated by 112, and in the details of the illustrated embodiment, it is shown as three protrusions 112a, 112b, and 112c. A plurality of protrusions 112 protrude from an outer portion 114, with angular spacing between the protrusions. In the illustrated embodiment, the angular spacing is approximately 55°, so that the central protrusion 112b is approximately at the 9 o'clock position, the adjacent protrusion 112a is at the 11 o'clock position, and the adjacent protrusion 112c on the other side is at the 7 o'clock position. The inner portion 113 defines a receiving space for receiving at least a portion of the pivot pin 23 and at least a portion of the slide rail 22, and the inner portion 113 is formed with a shape that complements the shape of the slide rail 22 and the shape of the pivot pin 23. The first element 11 also includes a connecting pin 111. The connecting pin 111 extends from the outer portion 114 and is intended to be used to connect the first element 11 to the second element 12. Finally, the outer portion 114 includes a recessed portion 115 to accommodate movement of the first element 11 relative to the rest of the hinge 5. The outer portion 114 is formed into a generally cylindrical shape, with three protrusions 112a, 112b, and 112c extending radially from the outer portion 114, and the connecting pin 111 extending axially outwardly from the outer portion 114. The angular spacing between the protrusions is selected to allow for at least two distinct orientations, with due regard for the requirement that the rail 22 lies within the profile of the side member of the sash 2 in a first orientation and protrudes beyond the profile in a second orientation. Suitable angular ranges are 30° to 75°, typically about 45° to 60°.

[0044] The second element 12 includes a notch 124 formed by a bend in the beam 125. The notch 124 is configured to receive one of the protrusions 112 of the first element 11 at a time to define an associated orientation. In the illustrated embodiment, when the slide rail 22 is in the first orientation, the central protrusion 112b is received within the notch 124, and when the slide rail 22 is in the second orientation, the immediately adjacent protrusion 112a in the clockwise direction is received within the notch 124.

[0045] The engagement between the first element 11 and the second element 12 is configured as a form-locking engagement. When the protrusion 112 is moved into the first or second connected position, the protrusion 112 can be received in the recess 124 almost frictionlessly by creating a small gap between the protrusion 112 and the recess 124. This prevents any stress on the curvature of the recess in the beam 125. The beam 125 is formed so that it is resilient and allows for elastic deformation when the protrusion 112 is moved out of the recess 124. It is also conceivable to provide the protrusion with elastic properties or to otherwise provide one or more elastic components for the first element 11, the second element 12, or both.

[0046] The second element 12 further comprises a connecting flange 126 . Figure 3 Also shown is a connecting flange 126, which is intended for connecting the second element 12 to the base plate 21 of the hinge 20. The connecting flange 126 is configured to hook the second element 12 onto the base plate 21. When the handling and installation assembly 10 is connected to the sash hinge 20 of the hinge 5, the connecting flange 126 extends in a plane parallel to the base plate 21. The connecting flange 126 extends from a spacer element 121 of the second element 12. The spacer element 121 extends perpendicular to the connecting flange 126 and serves to distance a portion of the second element 12 from the base plate 21. The distance created by the spacer element 121 allows the slide rail 22 to move between the second element 12 and the base plate 21. The second element 12 also includes a snap connector 123, which is used to engage and connect the second element 12 to the base pin 24 of the hinge 20. The second element 12 also includes an indicator 122. The indicator 122 may correspond to or match the indicator 25 of the hinge 20 .

[0047] Thus, in the embodiment shown, the second element 12 is the left-hand element, whereas the first element 11 is symmetrical - see Figure 16 , Figure 16 A line of symmetry S is indicated in the figure - so that the same element can be used for both the left-hand hinge 5 and the right-hand hinge. It should be noted that the central protrusion 112b and the immediately adjacent protrusion 112a in the clockwise direction are used here with the left-hand sash hinge 20, and when used with the right-hand sash hinge, the central protrusion 112b and the adjacent protrusion 112c in the counterclockwise direction are used; however, it is also conceivable to form the first element as a custom element suitable for left-hand and right-hand versions respectively. Figure 17 and Figure 18 The second right-hand element 12 is shown.

[0048] Further references Figure 10 , shows a rear view of the second element 12 according to an embodiment of the present invention. The second element 12 includes a connecting hole 127 configured to receive the connecting pin 111 of the first element 11, thereby connecting the first element 11 to the second element 12. Referring again to Figure 5, as indicated, the handling and mounting assembly 10 is connected to the sash hinge 20. In a first step, the sash hinge 20 is provided. In a second step, the first element 11 is connected to the sash hinge 20. The first element 11 is connected by pressing the inner portion 113 of the first element onto the slide rail 22 and the pivot pin 23. In a third step, the second element 12 is connected to the base plate 21 and the first element 11. The second element 12 is connected to the base plate 21 by hooking the connecting flange 126 onto the base plate 21 and connecting the snap connector 123 to the base pin 24. In some embodiments not shown, the second element 12 is connected only via the connecting flange 126 or the snap connector 123 or by any other means. When the second element 12 forms an angle with the first element 11 and the sash hinge 20 , the second element 12 is connected to the first element 11 by allowing the connecting hole 127 to receive the connecting pin 111 and then rotating the second element 12 so that the snap connector 123 can snap onto the base pin 24 .

[0049] During the installation of the roof window 1, the sash 2 needs to be repeatedly handled during installation in order to be able to install the frame 3 in the roof structure and to confirm that the fit between the sash 2 and the frame 3 is correct. Typically, the roof window 1, including the sash 2 and the frame 3, is removed from its supplied state in suitable packaging, and the sash 2 is subsequently separated from the frame 3 and stored separately, while the frame 3 is installed in the roof structure. During this initial handling and storage, the handling and installation assembly 10 is placed in its first orientation.

[0050] exist Figure 12 , the handling and mounting assembly 10 is shown connected to the sash hinge 20 of the left hand hinge 5. The sash hinge 20 is in turn fastened to the side members of the sash 2. Figure 12 1 shows a first orientation in which the central protrusion 112 b of the first element 11 is received in the recess 124 of the second element 12, making it possible to transport the window sash 2 while the rail 22 remains seated within the contour of the window sash 2. Thus, the risk of the rail 22 swinging outwards beyond the contour of the window sash 2 and thus getting stuck and deforming or causing damage to parts of the building is eliminated.

[0051] Once the sash 2 has been reattached to the frame 3, the handling and mounting assembly 10 is placed in its second orientation by rotating the slide rail 22 and therefore the first element 11 until the immediately adjacent protrusion 112a (in the left hand hinge 5 in the embodiment shown) is received in the recess 124 of the second element 12, providing a position distinct from the first orientation. This operation is repeated at both sides of the sash 2. The sash 2 is then held in the appropriate position for attachment or reattachment to the frame 3, i.e. so that the sash hinge 20 is located at the frame hinge 30 at either side of the frame 3. This is done in Figure 13 is shown in Figure 13 It can be seen that the rails 22 protrude beyond the profile of the side members of the sash 2. In this way, the installer can easily introduce the rails 22 at either side of the sash 2 into the first inlet 34 of the arcuate guide 32 in the frame hinge 30.

[0052] Reference Figure 14 , Figure 14 A partial front view of a handling and mounting assembly 10 according to another embodiment of the invention is depicted. Only the differences with respect to the embodiment described above will be described in detail, and elements having the same or similar functions are denoted by the same reference numerals. In the embodiment shown, the outer portion 114 of the first element 11 comprises at least one protrusion, here two protrusions 112a and 112b. The second element 12 comprises a plurality of recesses, here a first recess 124a and a second recess 124b. In Figure 14 In the position shown, the protrusion 112a engages the first recess 124a, thereby obtaining a first orientation corresponding to the transport position. To place the transport and mounting assembly 10 in the second orientation, the slide rail 22 and the first element 11 are rotated so that the protrusion 112a is received in the second recess 124b.

[0053] Although the above embodiment has been described as providing two distinct orientations of the transport and installation assembly 10, namely the first orientation and the second orientation, the present invention is not limited to only two distinct orientations. The first element and the second element can engage with each other to temporarily lock the slide rail in the third orientation and / or the fourth orientation.

[0054] In an embodiment comprising three protrusions 112a, 112b, 112c and a single notch 124, three different orientations can therefore be provided. Figure 14 In an embodiment, it is contemplated that each of the two protrusions 112a and 112b is allowed to engage the first recess 124a and the second recess 124b in at least two different orientations of the slide rail 22 on which the transport and installation assembly is mounted.
