Description

Technical Field

[0001] This utility model relates to a corner assembly auxiliary device for a roof window sash, and to a roof window having a sash comprising sash components interconnected by corner fittings. Background Technology

[0002] Assembling window sashes, for example, for roof windows, requires connecting individual sash components at angles to create each corner of the sash. This can be troublesome, and improper connections at the ends of the sash components can not only affect the appearance of the sash but also make it more susceptible to deterioration and water leakage.

[0003] Corner fittings are used to reinforce corner joints of window sashes and are already well-known.

[0004] An example is known from FR472784A, which describes the manufacture of a wooden window sash with metal corner fittings. The corner fitting is inserted into a groove in the wooden window sash component, and a nail is driven through a notch in the corner fitting, thereby forming a tongue that anchors itself to the wood.

[0005] This type of corner fitting is not well-suited for use with window sash components made of profiles, for example, metal.

[0006] Another, and slightly more complex, example is known from EP0644312A2, which describes a corner fitting for connecting window sash members made of hollow profiles with ends cut at 45°. Two flat, stacked corner bars are inserted into the ends of two adjacent window sash members, and the window sash members are fastened to each other by tension screws and engaging devices that hook into openings in the window sash members.

[0007] The disadvantage of the latter type of corner fitting is the risk that the window sash components, made of profiles such as those produced by extrusion, may not be properly aligned and / or adequately connected, making the window sash components prone to deterioration and water leakage. Furthermore, this corner joint has the disadvantage that the connection between the two window sash components and the corner fitting requires a hollow, closed profile, wherein the corner fitting can engage with the opposite inner part of the hollow, closed profile. Therefore, a robust connection of the window sash components is achieved at the expense of efficient space utilization. Utility Model Content

[0008] Therefore, in this context, one object of the present invention is to provide a corner assembly aid that is suitable for use with profile window sash components and helps to precisely connect the window sash components to each other.

[0009] In a first aspect of this invention, this and other objectives are achieved by a corner assembly aid for a roof window sash, the corner assembly aid comprising a support column defining a longitudinal axis of the corner assembly aid and a corner fitting support having a first support section and a second support section, wherein each of the first and second support sections protrudes from the support column, the first support section extending along a first width axis and the second support section extending along a second width axis, each of the width axes being perpendicular to each other and perpendicular to the longitudinal axis, and wherein the first and second support sections together form a corner fitting support surface.

[0010] The first support section and the second support section together form a corner fitting support surface, which extends between the first width direction and the second width direction and is perpendicular to the longitudinal axis.

[0011] In other words, the corner fitting support surface forms a corner fitting support, wherein the corner fitting support is defined by a plane extending across the area between the first support section and the second support section, the first support section and the second support section protruding from the support column perpendicular to the longitudinal axis and defining the surface area of ​​the corner fitting support.

[0012] A corner assembly aid with a support column and corner fitting support section allows for precise, angled connection of window sash components in a compact manner, effectively assisting and guiding the correct assembly of the window sash components. The first and second support sections are positioned at approximately the same longitudinal location on the support column and thus together form a corner fitting support surface for placing the corner fitting on it. As the support column extends vertically, the corner fitting support surface extends horizontally, and the corner fitting rests on the corner fitting support surface under the influence of gravity.

[0013] During the fastening of the corner fittings to the window sash components, the corner fittings can be placed on the corner fitting support surface, thereby facilitating the assembly of the window sash.

[0014] In an embodiment of the first aspect, the corner assembly aid includes at least a pair of connector arms projecting from a post, wherein each connector arm defines a connector axis extending perpendicular to the longitudinal axis and parallel to the width axis, and wherein the connector axes intersect at the post.

[0015] Each connector arm can be placed in a complementary recess in the sash component, thus connecting the corner assembly aid to the sash component and further facilitating the assembly of the sash component of the roof window. The connector arms project from the post, guiding the ends of the sash components toward each other and arranging the sash components at the same angle relative to each other as the connector arms to a position where the sash components may abut against the post. When the sash components are connected to the corner assembly aid, the connector arms intersect at the post, preferably at a 90° angle, to form a rectangular sash.

[0016] It should be understood that the corner fitting will be the primary load-bearing element of the corner joint, while the connector arm may only serve as a guide during window sash assembly. In some embodiments, the connector arm will also help secure the corner joint in the assembled state and / or may be used to transfer loads from one window sash component to another.

[0017] In another embodiment of the first aspect, the corner assembly aid includes two pairs of connector arms, wherein the connecting axes of the first pair of connector arms intersect at a first longitudinal position on the support, and the connector axes of the second pair of connector arms intersect at a second longitudinal position.

[0018] Two pairs of connector arms will provide a stronger and more reliable connection between the window sash component and the corner assembly aid. The second pair of connector arms will also further facilitate easier insertion of the connector arms into the grooves of the window sash component. Arranging two pairs of connector arms at a certain distance from each other along the longitudinal axis can also aid in the alignment of the window sash component.

[0019] In another embodiment of the first aspect, the corner assembly aid includes a first longitudinal position and a second longitudinal position, the first longitudinal position and the second longitudinal position being positioned on opposite sides of the corner fitting support.

[0020] Providing connector arms on the opposite side of the corner fitting support further facilitates the precise connection between the corner assembly aid and the window sash components, and thus, through extension, aids in the connection between the window sash components. In this embodiment, viewed along the longitudinal axis, the load transfer provided by the corner fitting will be centered toward the corner assembly aid, and the guiding and / or fixing function of the connector arms will be established on the opposite side of the corner fitting, thereby aiding in the proper alignment of the window sash components. Incorrect connection of window sash components in troublesome areas such as near the edge of the corner joint can, for example, result in small openings for water to enter the window structure, and therefore it is preferable to position the connector arms near the ends of the supports. Thus, the arrangement of connector arms on the opposite side of the corner fitting support facilitates a tight connection of the window sash components evenly distributed along the entire length of the corner joint, thereby making the proper assembly of the window sash components easier.

[0021] In another embodiment of the first aspect, the corner fitting support further includes at least one insertion stop, wherein the corner fitting support surface and the insertion stop define a corner fitting space for receiving the corner fitting, the corner fitting space preferably being distanced from the post. The additional insertion stop, combined with the corner fitting support surface, defines a designated corner fitting space for properly placing the corner fitting, allowing the corner fitting to be easily positioned in the intended location for fastening to the window sash component by inserting the corner fitting until it contacts the insertion stop. This provides a fixed space for receiving the corner fitting and facilitates easier assembly of the window sash component. This aids in the precise positioning of the corner fitting on the corner fitting support surface.

[0022] The insertion stop can be positioned on the support section.

[0023] In another embodiment of the first aspect, a water flow space exists between the corner fitting space and the support column, the water flow space communicating with at least one drainage opening in or adjacent to the corner fitting support. The water flow space can be configured to receive any water flowing along the support column along a water flow path and further guide the water to the drainage opening. The drainage opening is preferably positioned such that any water entering the drainage opening will be discharged onto the roof. It is anticipated that only a small amount of water will be present, for example, through condensation, or water being forced through small openings between window sash components or between window sash components and corner assembly accessories. This design reduces the likelihood of water stagnation at window corners by facilitating water drainage, which over time can weaken the structural integrity. This design helps extend the lifespan of the roof window. Reduced contact with water reduces the need for frequent maintenance, decreases the likelihood of water-related problems, and minimizes maintenance costs.

[0024] In another embodiment of the first aspect, the corner fitting support further includes a support overhang, wherein the support overhang is connected to a post along a longitudinal axis at a distance from a first support segment and a second support segment, the first and second support segments, and the support overhang defining a corner fitting space for receiving the corner fitting. The support overhang helps to hold the corner fitting on the corner fitting support surface, and as described above, the corner fitting space helps to position the corner fitting in its intended position on the corner fitting support surface. By combining the insertion stop and the support overhang, the support segments, the insertion stop, and the support overhang define a three-dimensional space. This provides easier and more secure placement of the corner fitting for connection to the window sash component, thereby further aiding in the correct assembly of the window sash.

[0025] It should be understood that terms such as “up,” “down,” “above,” “below,” “left,” “right,” “exterior,” “interior,” “outer,” and “inner” are relative and relate to the perspective in the discussion. For example, in the assembled state of a window, the support cantilever is positioned “above” the corner fitting support relative to its position. Flipping or otherwise repositioning the corner assembly aid or roof window should not deviate from this meaning.

[0026] In a second aspect of this invention, the objective of this invention is achieved by a roof window comprising a frame, window sashes, and window panes.

[0027] The frame includes a set of frame members, which includes a first pair of generally parallel frame members and a second pair of generally parallel frame members.

[0028] The window sash includes a set of window sash components, which includes a first pair of generally parallel window sash components, a second pair of generally parallel window sash components, at least one corner fitting, and at least one corner assembly auxiliary device according to the first aspect of the present invention.

[0029] The corner assembly auxiliary device has a support column positioned between the first window sash member in the first pair of window sash members and the second window sash member in the second pair of window sash members. The first support section and the second support section each extend along one of the two window sash members.

[0030] The corner fitting is placed on the corner fitting support surface and connected to the first window sash component and the second window sash component.

[0031] By providing corner assembly aids in the roof window, simplified assembly of the window sash as described above with reference to the first aspect is achieved, and even the window sash components are connected in a precise manner, which improves the structural integrity of the window sash. By providing precise and rigid connections for the window sash components, the window sash becomes more robust, thereby reducing the risk of deformation, warping, or misalignment over time, as well as frame deterioration, such as that caused by water penetration.

[0032] Those skilled in the art will understand that the first pair of generally parallel window sash components and the second pair of generally parallel window sash components, when combined, will form an assembled window sash in a generally rectangular shape.

[0033] Furthermore, it should be understood that corner fittings placed on the support surface of corner fittings in roof windows can refer to corner fittings fastened to window sash components, even if the corner fittings can be lifted wholly or partially from the support surface of corner fittings during window sash assembly.

[0034] In a second aspect embodiment, each connector arm is arranged in a groove of a window sash member, and each connector arm is engaged by a convex portion of the window sash member, the convex portion interlocking with a concave portion of the connector arm, preferably wherein the convex portion is a deformable portion on the window sash member.

[0035] The window sash component, interlocked with the corner assembly aid, provides elements for further securing the connection to the window sash component. This allows the connector arm to transfer loads from one window sash component to another and / or prevents the window sash component from unintentionally separating from the corner assembly aid, for example, during assembly.

[0036] The connector arm may include a concave portion that engages with a convex portion in the groove. It should be understood that the connector arm may include either a convex or concave portion, and similarly, the groove may include either a convex or concave portion, provided that the groove and the connector arm have complementary engagement portions to form an engagement.

[0037] The engagement between each connector arm and the groove of the window sash component can be achieved simply by positioning the connector arm into the groove, thus achieving an initial connection before the corner fitting is fastened to the window sash component. This engagement facilitates easy connection, holds the window sash component in place, and connects to the corner assembly aid while the corner fitting is fastened to the window sash component.

[0038] The convex portion may include a protrusion configured to engage the concave portion by pushing the protrusion into a spring bias when the connector arm is positioned in the recess.

[0039] The concave portion can be a groove or pit constructed to receive the convex portion.

[0040] The convex portion may include a deformable part on the window sash component that locks the connector arm in place.

[0041] Furthermore, when the connector arm is placed in the groove, the engagement of the connector arm in the groove can be facilitated by adhering the adhesive placed in the groove to the connector arm or hardening it around the connector arm.

[0042] In some implementations, where the corner assembly aid includes two pairs of connector arms, the sash member can be connected to the strut by deforming the flange of the sash member into only the first or second pair of connector arms. This may be the case, for example, in smaller roof windows, where the forces affecting the corner joint bear relatively low loads.

[0043] In some embodiments, the first and second longitudinal positions on the strut may be equidistant or symmetrically spaced from corresponding opposite ends of the strut. In this embodiment, when the window is oriented to one side, the connection between the window sash member and the strut may be provided by a first pair of connector arms initially connected to the window sash member. Subsequently, the window is flipped or reversed to allow a second pair of connector arms to connect to the window sash member.

[0044] Alternatively, the flanges of the sash component at all connector arms can be deformed simultaneously, for example, by arranging the sash component, which is loosely connected to the corner assembly auxiliary device, within the limiting frame and using a deformation tool having a punch for each connector arm, and simultaneously pressing outward toward the limiting frame at the locations of all connector arms.

[0045] The process of connecting window sash components to corner assembly aids can be accomplished using mechanical or automated equipment that deforms one or more flanges of the window sash components.

[0046] In some implementations, the window sash components can be directly glued or adhered to the support.

[0047] In another embodiment of the second aspect, the roof window includes a plurality of fasteners, each of which protrudes through the window sash member and enters into a corner fitting. The fasteners may be, for example, screws, bolts, rivets, or combinations thereof.

[0048] In a preferred embodiment, the window sash component is provided with a fastener opening for allowing the fastener to protrude and insert into the corner fitting.

[0049] One or more window sash components may be made of hollow profiles with closed internal units, except that they may have openings at the ends. Alternatively or additionally, one or more window sash components may be made of open profiles without internal units.

[0050] In another embodiment of the second aspect, each window sash member includes an inner portion facing the window pane and an outer portion opposite to the inner portion, wherein a protrusion extends from the inner portion, and wherein the fastener protrudes through the protrusion. Thus, the protrusion of each window sash member is used to transfer loads from one window sash member to another. The protrusion can also be used to support the window pane of a roof window.

[0051] Fasteners can protrude directly through protrusions and / or corner fittings, but it is currently considered advantageous to provide fastener openings to the fasteners.

[0052] Fasteners protruding through the fastener openings in the corner fittings and entering the window sash component are positioned via a corner fitting space configured to position the corner fitting so that the fastener openings in the window sash component are substantially aligned with the fastener openings in the corner fitting. These combined features allow the corner fitting space to facilitate easy fastening to the window sash component while also allowing the corner fitting to be held in place to ensure proper alignment of the fastener openings in the corner fitting and the fastener openings in the window sash component.

[0053] In a second embodiment, the strut protrudes between the window sash members at the corner joint, forming part of the outer surface of the window sash. Therefore, the corner joint, by being isolated by the strut, provides improved protection from environmental influences and long-term reliability. In this way, a window sash assembly is provided in which the strut forms a defined connection structure between the ends of the window sash members. Thus, the corner joint will have improved protection from environmental influences, reducing degradation and exposure of the ends of the window sash members. Furthermore, any irregularities on the end faces of the window sash members may be concealed by the strut and remain unobserved. If the window sash members are made of profiles with a surface coating such as paint and have been cut to a length that interrupts the surface coating, then the strut can cover the end faces exposed due to the cut.

[0054] As explained above with reference to the first and second aspects of this utility model, the assembly of window sashes for roof windows is simplified and made easier by using corner assembly aids and corner fittings.

[0055] The window sash for roof windows can be assembled using an assembly method according to the corner assembly auxiliary device of this utility model, wherein the window sash includes:

[0056] A set of window sash components, comprising a first pair of generally parallel window sash components and a second pair of generally parallel window sash components, the method comprising the following steps:

[0057] a) Provides multiple window sash components, corner fittings, and corner assembly aids, wherein each corner assembly aid includes a support column defining the longitudinal axis of the corner assembly aid and a corner fitting support having a first support section and a second support section, wherein each of the first support section and the second support section protrudes from the support column perpendicular to the longitudinal axis, and wherein the first support section and the second support section together form a corner fitting support surface;

[0058] b) Arrange the first corner assembly auxiliary device between the first window sash component in the first pair of window sash components and the second window sash component in the second pair of window sash components, such that the first support section and the second support section each extend along one of the two window sash components, thereby connecting the first window sash component and the second window sash component at a certain angle to form a corner of the window sash.

[0059] c) Arrange the corner fitting on the corner fitting support surface and use fasteners for connecting the corner fitting to the first window sash component and the second window sash component to secure the corner of the window sash.

[0060] d) Repeat steps b) and c) to form and secure one or more other corners of the window sash.

[0061] In this way, by providing corner fittings and fastening them to the window sash components, the window sash for a roof window can be assembled by means of a forced connection with the window sash components, thus strengthening the corner assembly. The corner assembly includes a corner assembly aid that positions and supports the corner fittings during assembly and connects to the first and second window sash components in the assembled state. Therefore, through the connection with the corner assembly aid, the first and second window sash components connected to the corner assembly aid are connected at an angle.

[0062] The corner assembly auxiliary device is provided with at least a pair of connector arms protruding from the support post, wherein each connector arm defines a connector axis extending perpendicular to the longitudinal axis, and wherein the connector axes intersect at the support post. The method further includes the following steps:

[0063] e) The first corner assembly auxiliary device is connected to the first window sash component by arranging one of the connector arms in the groove of the first window sash component and engaging it with the convex portion of the first window sash component such that the convex portion interlocks with the concave portion of the connector arm.

[0064] f) By arranging one of the connector arms in the groove of the second window sash component and engaging it with the convex portion of the second window sash component such that the convex portion interlocks with the concave portion of the other connector arm, the first corner assembly auxiliary device connected to the first window sash component is connected to the second window sash component.

[0065] This allows the window sash components to be connected to the corner assembly aid by joining the convex and concave portions, thereby connecting the window sash components to each other at an angle to form a corner.

[0066] The method may also include forming at least one convex portion of a window sash component by deforming the window sash component during assembly.

[0067] By deforming the window sash component into or around the connector arm in a locking position, the connection between the corner assembly aid and the window sash component is strengthened. This deformation acts as a convex portion engaging a concave portion in the connector arm, thereby interlocking the window sash component and the connector arm together.

[0068] Unless otherwise stated, the embodiments and advantages described with reference to one aspect of the present invention also apply to other aspects of the present invention. Attached Figure Description

Detailed Implementation

[0084] Preferred embodiments of the present invention will be described in the following detailed description. However, it should be understood that, unless otherwise specifically indicated, features of different embodiments are interchangeable between them and can be combined in different ways. It should also be noted that, for clarity, the dimensions of certain components illustrated in the drawings may differ from their corresponding dimensions in the actual implementation.

[0085] Reference Figures 1A to 3B The illustration shows an embodiment of a corner assembly aid 100 and a corner fitting 170 for a roof window sash.

[0086] The corner assembly auxiliary device 100 includes a support column 110 that defines the longitudinal axis L of the corner assembly auxiliary device and a corner accessory support 130.

[0087] The corner fitting support 130 has a first support section 131A and a second support section 131B. Each of the support sections 131A and 131B protrudes from the support column 110, wherein the first support section extends along a first width axis WA1, and the second support section extends along a second width axis WA2, and wherein each of the width axes is perpendicular to each other and perpendicular to the longitudinal axis L. Together, the corner fitting supports form a corner fitting support surface 133.

[0088] In this embodiment, the corner fitting support 130 has an insertion stop 135 on each support segment 131A, 131B, which protrudes along the longitudinal axis L to provide a stop for the insertion of the corner fitting 170. The stop prevents the corner fitting 170 from being placed on the corner fitting support surface 130 closer to the support post 110 than intended. In some embodiments, a distance is provided between the corner fitting 170 and the support post 110 when the corner fitting 170 abuts against the insertion stop 135. The insertion stop can be implemented in a manner different from that shown, as long as the insertion stop is used to stop the insertion of the corner fitting, and there can be only a single insertion stop that can span from one support segment 131A to another support segment 131B.

[0089] The corner fitting support surface 133 and the insertion stop 135 define the corner fitting space 139 in a plane perpendicular to the longitudinal axis L, and the corner fitting space 139 accommodates... Figure 1A The corner fitting 170 is shown in an assembled state. In a preferred embodiment, the corner fitting space 139 is located away from the support column 110.

[0090] The exact dimensions and shape of the corner fitting support surface 133 may differ from those shown and may depend on the dimensions and shape of the corner fitting 170.

[0091] In the illustrated embodiment, the corner fitting space is further defined by a support overhang 137, which is connected to the support column 110 along the longitudinal axis L at a certain distance from the first support section 131A and the second support section 131B.

[0092] like Figure 1A As can be seen, the corner fitting space 139 allows for precise positioning of the corner fitting relative to the support column 110.

[0093] The corner fitting 170 includes a fastener opening 171, wherein the fastener 200 is configured to connect the corner fitting 170 to a window sash member of a roof window, thereby connecting the window sash members to each other in a corner configuration, as described later.

[0094] Two pairs of connector arms 150 and 160 are provided, including connector arms 150A, 150B; 160A, 160B, with connector arms 150A, 150B; 160A, 160B protruding from the support 100. Each connector arm defines the connector axis CA (only when...). Figure 1BAs shown in the diagram, the connector axis CA extends perpendicular to the longitudinal axis L and parallel to the corresponding width axis. The connector axes CA of each pair of connector arms intersect at the support 110. The connector axes CA of the first pair of connector arms 150 intersect at a first longitudinal position L1 on the support 110, and the connector axes CA of the second pair of connector arms 160 intersect at a second longitudinal position L2. The first longitudinal position L1 and the second longitudinal position L2 are located on opposite sides of the corner fitting support 130.

[0095] In some embodiments, the corner assembly aid 100 may have a pair of connector arms, while in other embodiments, the corner assembly aid 100 may not have any connector arms.

[0096] Connector arms 150A, 150B; 160A, 160B each have a concave portion 151 configured to interact with a convex portion located in a groove in the window sash member to facilitate the connection of the connector arm to the window sash member, as described later.

[0097] The corner assembly aid shown also includes an abutment member 180 that abuts against the window sash members in the assembled state, thereby holding the corner assembly aid and thus the corner fitting at a predetermined distance from the inner side of each window sash member. The abutment member 180 provides a smaller contact area between the corner assembly aid 100 and the inner side of each window sash member to reduce friction and provides smoother movement between the inner side of the window sash member and the corner assembly aid 100 when they are joined. In some embodiments, the abutment member 180 may be spherical or circular in shape to provide the smallest possible contact area.

[0098] The corner assembly aid 100 shown also includes a recessed profile 182 provided on the first support section 131A and the second support section 131B. In this embodiment, the recessed profile 182 is shaped as an inclined channel that gradually rises along its length. When the window is in its assembled state, the open window may exhibit swaying motion caused by external forces such as wind conditions, resulting in slight misalignment between the open window sash and the frame, making it difficult to close the window smoothly. The recessed profile 182 can serve as a guide, helping to return the window sash to alignment with the frame when the window is closed. (See reference...) Figure 4a and Figure 4b as well as Figure 5 An embodiment of a roof window 1 including a frame 7, a window sash 5, and a window pane 3 is shown. Figure 4a In the middle, roof window 1 is installed on roof 300 in a single installation manner, while Figure 4b In the middle, three roof windows are installed side by side on the roof structure 300. Figure 5 Details in Figure 4a The symbol is marked as V, and it should be understood that, Figure 4b The three roof windows and Figure 4a It is the same as one of the roof windows.

[0099] Frame 7 includes a set of frame members 70, which comprises a first pair of generally parallel frame members and a second pair of generally parallel frame members arranged in a square. Window sash 5 includes a set of window sash members 50, which comprises a first pair of generally parallel window sash members and a second pair of generally parallel window sash members. The window sash members 50 are arranged in a square structure complementary to frame 7. Each window sash member 50 is connected to another window sash member 50 by means of corner fittings, as will be referred to... Figure 7 As described, the support column 110 of the corner assembly auxiliary device 100 is located between the ends of the window sash components, thereby forming part of the outer surface 57 of the window sash. The window sash 5 is positioned on top of the frame 7 to project onto the outer surface 77 of the frame and to provide an edge for the window pane 3 supported by the window sash 5.

[0100] Reference Figure 6 The illustration shows an embodiment of a window sash member 50 made of an open profile without internal units. This type of profile would typically be made of metal, such as aluminum, or of a fiber-reinforced polymer, and would typically be manufactured by extrusion.

[0101] The window sash component 50 includes an inner portion 59 facing the window pane 3 and an outer portion 57 opposite to the inner portion 59.

[0102] like Figure 8 As seen in the image, the protrusion 53 protruding from the inner side 59 is provided with a fastener opening 55, which is used to fasten the corner fitting to the window sash component 50.

[0103] like Figure 8 As shown, a groove 51 is provided on the opposite side of the protrusion 53 and is configured to receive the connector arm 150 on the corner assembly aid 100. Each groove 51 is defined by a flange 52 that protrudes in opposite directions along the longitudinal axis L and extends along the length of the sash member 50 perpendicular to the longitudinal direction, thereby forming a groove together with the inner side 59 of the sash member 50.

[0104] Figures 7 to 8 The implementation of the corners of the roof window 1 and window sash 5 is shown. Only one corner fitting 170, one corner assembly aid 100 and a set of fasteners 200 are shown, but it should be understood that all corners of the window sash 5 can be implemented in the same manner.

[0105] Similarly, Figure 5As shown, the support column 110 of the corner assembly auxiliary device 100 is arranged between the two window sash components 50. Figure 7 Only one of the two window sash components 50 is shown in the image; the other has been removed to show the corner assembly aid 100 and corner fitting 170.

[0106] The first support section and the second support section each extend along one of the two window sash members 50, and the corner fitting 170 rests on the corner fitting support surface 133. Figure 7 In the middle, only the first support section 131A is visible; the second support section is hidden behind the window sash component, while... Figure 8 In the middle, both support sections are hidden under the corner fitting 170.

[0107] The corner fitting 170 is connected to the first window sash component and the second window sash component 50 by a plurality of fasteners 200. The fasteners 200 protrude through the fastener opening 55 in the protrusion 53 of the window sash component 50 and into the fastener opening 171 in the corner fitting 170, thereby connecting the window sash component 50 and the corner fitting 170 to each other.

[0108] Each of the connector arms 150 is arranged in a recess 51 of the window sash member 50, wherein the connector arm 150 can be engaged by a convex portion of the window sash, the convex portion being referenced. Figures 1A to 3B The concave portion 151 on the connector arm is interlocked. For example, the convex portion can be formed by deformation of the flange 52 of the window sash member, such that a portion of the flange protrudes into the concave portion 151 in the connector arm 150.

[0109] To assemble two window sash components 50 at a corner 54 using a corner assembly aid 100, the corner assembly aid 100 can be arranged between the first window sash component 50 and the second window sash component 50, such that the first support section 131A and the second support section 131B each extend along one of the two window sash components 50, and the connector arms 150 and 160 of the corner assembly aid 100 are brought into the groove 51 of the window sash component 50. Since the support section and connector arm of each component extend at an angle to each other, the window sash components will also extend at an angle to each other, thereby forming the first corner 54.

[0110] Now, the corner fitting 170 is disposed on the corner fitting support surface 133, and thereafter the fastener 200 is used to connect the corner fitting 170 to the first window sash member 50 and the second window sash member 50 to establish a fixed window sash corner. Alternatively, the corner fitting can be disposed on the corner assembly aid 100 before the window sash member comes into contact with the corner assembly aid, or one window sash member can come into contact with the corner assembly aid, then the corner fitting is added, and then the other window sash member comes into contact with the corner assembly aid.

[0111] Once the first corner component 100 has been formed, the second, third, and fourth corner components can be formed by repeating the preceding steps.

[0112] If the corner assembly aid 100 includes a connector arm with a concave portion, each window sash member 50 can be connected to the corner assembly aid by engaging the concave portion 151 in the connector arm 150 with the convex portion in the groove 51 of the first window sash member 50 and thereby interlocking the connector arm 150 with the first window sash member 50.

[0113] A convex portion can be formed by deforming a part of the window sash component 50 around or in a locking position within the concave portion 151 of the connector arm 150. This locks a part of the window sash component 50 around or within the connector arm 150 and interconnects the corner assembly aid 100 with the window sash component 50.

[0114] Reference Figure 9A , Figure 9B and Figure 10 An alternative embodiment of the corner assembly aid 100 and corner fitting 170 is shown. In this embodiment, the corner fitting support surface 133 and the insertion stop 135 define a corner fitting space 139 in a plane perpendicular to the longitudinal axis L, the corner fitting space 139 accommodating Figure 9B The corner fitting 170 is shown in an assembled state. In this embodiment, the corner fitting space 139 is located away from the support column 110. Figure 10 As seen in the image, the corner fitting 170 in this embodiment includes a rounded corner 173, which is consistent with... Figure 3A and Figure 3B Compared to the corner fitting 170 with a sharp corner shown, the rounded corner 173 provides a greater distance between the support column 110 and the corner fitting 170.

[0115] Figure 11A , Figure 11B as well as Figure 12A , Figure 12B As shown Figure 9AThe illustrated corner assembly aid 100 is connected to two window sash members 50 by a plurality of fasteners 200. The fasteners 200 protrude through fastener openings in protrusions 53 of the window sash members 50 and into fastener openings 171 in the corner fitting 170, thereby connecting the window sash members 50 and the corner fitting 170 to each other. The distance between the corner fitting space 139 and the support post 110 provides a water flow space 186 configured to receive water flowing along the water flow path WF along the support post 110. Due to the distance between the corner fitting space 139 and the support post 110, water flows to the portion of the corner fitting support surface 133 not covered by the corner fitting 170. The water flow space 186 directs the water to a drain opening 184 for drainage. From the drain opening 184, the water flows along the inner side 59 of the support post 110 or the window sash member and is ultimately guided onto the roof 300. Although only a small amount of water is expected, it is considered advantageous to be able to drain condensate and / or water that has seeped between the two window sash components that are joined at the joint.

[0116] Reference Figure 13A , Figure 13B and Figure 13C An embodiment of a corner assembly aid 100 including a column mortise 111 on each side of the column 110 is shown. The column mortise 111 has a shape complementary to the end profile of the window sash member 50, such that when also as Figure 11A and Figure 12A As shown, when the window sash component 50 is connected to the corner assembly auxiliary device 100, the geometry of the end profile of the window sash component is fitted into the post tenon 111.
