Description

DESCRIPTION

A roof window with an improved hinge and a cover assembly, and a method of providing such a hinge and a cover assembly

Field of the Invention

The present invention relates to a roof window having a frame and a leaf, comprising a set of hinges, each of the hinges including a part of the frame hinge and a part of the leaf hinge configured to assume an angle with respect to the hinge part of the frame, a cover arrangement that includes a side cover element of the frame and a side cover element of the sheet arranged to cover at least said hinge, and a hinge and cover assembly for mounting the cover arrangement on the hinge that includes at least one pressure connection, the pressure connection of the hinge and the cover assembly comprising at least one pressure anchor connected to the cover arrangement and being configured for a releasable connection directly to at least one integral retaining clip with the hinge and arranged to receive said at least one pressure anchor. The invention further relates to a method of providing a hinge and cover assembly.

Previous Technique

Basically, the roof windows can be provided in different varieties and include more or less complicated structures to allow the opening of the sheet and to fulfill other functions, such as ventilation, while allowing cleaning of the exterior of the panel from inside the building . The varieties include roof windows of the pivoting type, the hinge axis being located in the center or offset from the center of the window, and hanging ceiling windows that pivot for cleaning by means of an intermediate frame.

These requirements are made possible by the provision of a hinge with a particular pattern of movements, which in turn makes it possible to establish an overlap between the cover element fixed to the frame and the homologous cover element attached to the leaf in the closed position of The roof window. In such a hinge, the cover elements thus generally comprise at least two parts, one for covering the hinge part of the sheet and another covering the hinge part of the frame. The cover elements are designed to protect the hinge and the interior parts of the window against, among other things, the weather, dirt and grime, as this can cause the hinge to rust and, in the worst case. cases, the window drips water from the rain and, therefore, cause damage. The two cover elements are designed to allow angular movement with each other, when opening and closing the window. During the installation of the window, it is often necessary to disassemble the window cover elements in their supply condition and then reconnect them, which requires several stages. In the roof windows of the prior art, the cover elements are more often fixed by holding the cover element on the corresponding parts of the hinge, or the frame or the sheet itself, by means of fasteners such as screws.

An example of a roof window incorporating an improved fastening means is shown in the applicant document EP 2751 354 B1. In this arrangement, a male part of the fastening means connected to the cover element is coupled to the female part in the form of a plastic adjustment element connected to the hinge. In order to allow the disassembly and assembly of the cover elements, both the male and the female part are made of a plastic material, the male part of which is attached to the cover element by means of a rivet, generally a blind rivet or pop type Other examples are shown in WO 2013/050043 A1, corresponding to the closest state of the art, and EP 2607588 A2.

Common to the fastening solutions mentioned above is that they affect the surface of the cover elements, either in the form of an opening to receive the screw, or by the rivet that holds the male part, which makes it difficult to provide the finish wanted. In addition, the connection between the male and female fastening means, and with the hinge itself, can be uncomfortable, which leaves room for improvement.

Summary of the invention

With this background, an object of the present invention is to improve a roof window with respect to manufacturing and installation conditions.

In a first aspect, this and other objects are satisfied by the provision of a roof window of the type mentioned in the introduction, which is further characterized in that said pressure anchoring comprises a top surface configured to rest on a respective cover element, a guide portion and a coupling portion, said coupling portion comprising a tongue and two legs which extend from the upper surface of the pressure anchor and which meet at a lower point such that a groove is formed between the legs and the tongue.

This is an advantage, since the assembly procedure of the cover arrangement is made considerably faster than if the cover arrangement were fastened with additional fasteners. In addition, manufacturing and factory assembly of the roof window are facilitated, since the pressure anchor replaces both the plastic adjustment element connected to the hinge and the male part of the pressure connection of the technical arrangement previous. The pressure anchor therefore has more built-in functionalities. In this way, an anchor Pressurized can be pre-mounted on a cover element beforehand and snap into place when the hinge is installed. A hinge and cover assembly of this type can be formed in any manner suitable to fit the specific cover arrangement and the hinge to be used. The other components of the hinge with an integral retaining clip can be of a type presented in the request of the applicant in process with the present with the same filing date as the current application, although the hinge and cover assembly can be adapted basically to any type of hinge to improve Installation of the cover elements, provided that the hinge is modified accordingly. Finally, the need for additional tools and elements is reduced when installing the cover arrangement.

In a second aspect, a method is provided to provide a hinge and cover assembly in a roof window that has a frame and a sheet.

Other presently preferred embodiments and other advantages will be apparent from the following detailed description and the dependent claims.

Detailed description of the invention

In a manner known per se, the window comprises a sheet 2 carrying a glazing in the form of a panel 3 and a frame 1. The window is designed to be constructed on a surface, which is inclined with respect to the horizontal, typically a roof, and the window will be referred to below as a roof window. In a position between the top and the center of the window, there is a hinge connection between the frame 1 and the sheet 2. The hinge connection in Fig. 1 comprises a set of two prior art hinges, of the which is visible a hinge 10 '. Frame 1 and sheet 2 are each formed by four members, of which a side frame member 1a and a side sheet member 2a are indicated. The sheet 2 can be opened with respect to the frame 1, since the sheet 2 can be moved from a closed position, in which, for example, the side sheet member 2a is substantially parallel to the side frame member 1a, in a open position, in which the lateral leaf member 2a forms an angle with the lateral frame member 1a. During this movement, the blade 2 rotates around a hinge shaft a located at the hinge connection. As indicated in Fig. 1, the hinge axis a is located between a central axis and the upper part of the roof window, preferably in the range of 1/3 to 2/3 of the distance between the central axis and the upper part, most preferably substantially 1/2 of the distance between the central axis and the upper part. Of course, other hinge shaft positions are conceivable, for example, in the center of the roof window.

The same operation described above and hereafter is also valid for the type of hinge described in the Danish patent application of the applicant in process with this. PA 2015 70717 published on November 6, 2015. Other hinges in which the invention can be applied include pivot hinges that are described, for example, in applicant's patents EP 1038 083 B1 and EP 1781 883 B1, which are very versatile in Regarding operational areas and adaptation of components. Examples of roof windows incorporating such adapted hinges are shown in the published European patent applications of the applicant EP 2770 146 A1 and EP 2 770 149 A1. From a closed position, the user operates the operating device of the window. The operating device typically comprises a handle (not shown) connected to the lower leaf member and / or an operation and locking assembly that includes a ventilation flap in the upper leaf member with a locking mechanism for interacting with a plate hitting the upper frame member. As will be described in more detail below, the hinge 10 exerts a moment on the sheet 2, and in combination with the force, and therefore the moment, exerted by the user operating the operating device, the moment resulting from the weight of the sheet 2 and the panel 3 is overcome, together with any friction force present. Therefore, the opening operation implies that the sheet 2 moves from a closed position to an open position as shown in Fig. 1, in which the plane of the sheet forms an opening angle with the plane of the frame. Closing the window from the open position implies the opposite movement of the leaf 2. It is possible to place the leaf 2 in a series of arbitrary opening positions, in which the leaf 2 remains stable in relation to the frame 1. The leaf 2 also It can be rotated substantially 180 ° to allow cleaning of the exterior of panel 3 from inside the building in which the roof window is installed.

To protect the interior and the components of the window itself and to determine the weatherproof transition to the surrounding ceiling, the roof window comprises a cover, which includes flashing elements (not shown), cladding and covering elements of which a side cover element of frame 1b 'and the side cover element of sheet 2b' are shown. The roof window cover parts of the prior art are connected to the frame and the sheet, and to the hinge in a hinge and cover assembly as described in detail in the aforementioned embodiment of document e P 2751 354 B1.

With reference now to Figures 2 and 3, a first embodiment of a hinge and cover assembly 50 of the roof window according to the invention will be described in detail.

When referring to the Figures, the terms up, down, up, down, top and bottom are taken in relation to how the figures are shown, that is, having the frame arranged in a lying position with the elements on deck looking up. You take a front view of the hinge and looking towards the frame. Therefore, a view is taken from behind as seen from the frame towards the hinge. A longitudinal direction is, if nothing else is mentioned, longitudinal along the length of the frame. It should be understood that the arrangement shown in a horizontal orientation is not the normal orientation when the window is installed.

The hinge 10 comprises a hinge part of the frame 100 and a hinge part of the sheet 200 configured to assume an angle with respect to the hinge part of the frame 100. The hinge 10 is part of a hinge assembly, of which the hinge part of the frame 100 of each hinge 10 is configured to be attached to the side member of the frame 1a of the window frame 1 in a location chosen to provide the desired position of the hinge shaft a, and the hinge part of sheet 200 is correspondingly configured to be attached to the side member of sheet 2a. The hinge part of the frame 100 comprises a base plate 110 and the hinge part of the sheet 200 a base plate 210. Fixing the hinge to the respective side members of the frame and the leaf can take place in any suitable way, for example, as in the patent application in process with the present of the applicant with the same filing date as the present application.

As seen in Figs. 2 and 3, the connection of the side cover element of the frame 1b and the side cover element of the sheet 2b to the corresponding part of the hinge 100, 200 is carried out by a pressure connection 60, 70. Next, it will be described in more detail (cf. in particular, Figs. 4 to 7) how the pressure connection 70 is made by inserting a pressure anchor 80 connected to the cover element 1b in a retaining clip 90 connected to the base plate 110 of the part hinge frame 100 hinge 10.

The pressure anchor 80 is generally pre-mounted on a cover element 2b, 1b and the cover element can subsequently, after successfully installing the hinge 10, snap into place. This operation can save the installer a lot of time, as well as the need for loose fasteners. Referring again to Fig. 2, in which it also emerges how the side cover element of frame 1b and the side cover element of sheet 2b interact with each other; A crank portion 2c of the side cover element of the leaf 2b ensures a tight and level transition between the side cover element of the leaf 2b and the side cover element of the frame 1b in the closed position of the roof window. At the same time, the movement pattern of the hinge allows the side cover element of the leaf 2b to be able to retract from its position under the side cover element of the frame 1b during the opening movement of the leaf 2 relative to the frame 1, and reciprocally, be inserted under the side cover element of the frame 1b in the final stage of the closing movement.

Referring now to Figures 4 to 7, detailed views of a pressure connection 60, 70 are illustrated. Figure 4 shows a pressure connection 70 of the base plate 110 of the hinge portion of the frame 100. In general, the Pressure connection 60 may be identical in the hinge portion of the sheet 200, and therefore a view of any of the pressure connections 60, 70 is representative. In that way, the same pressure anchor 80 can be used in any of the fastening clips 90. However, the pressure connections 60, 70 can be arranged at different angles or orientations, depending on where the connections will be. The fastening clips 90 are preferably also symmetrical. The pressure anchor 80 is thus connected to the cover arrangement 1b, 2b and is configured for the releasable connection directly to a respective retaining clip 90 integral with the hinge 10 and is arranged to receive the respective pressure anchor 80. However, variations can occur without compromising the idea underlying the invention.

In Fig. 4 it is shown how the pressure anchor 80 must be placed in the corresponding clamping clip 90.

In the embodiment shown, the hinge part of the frame 100 and the hinge part of the sheet 200 each comprise a base plate 110, 210, and the retaining clip 90 is formed in the base plate 110, 210 of the hinge part 100, 200 respective.

Each holding clip 90 comprises a receiving portion 91 and a coupling portion of the anchor 92. The receiving portion 91 of the holding clip 90 is substantially U-shaped here and comprises two opposite supporting surfaces 93 extending between a surface of respective upper end 95 and the coupling portion of the anchor 92. The introduction of the pressure anchor 80 into the retaining clip 90 is facilitated if at least one of the opposite surfaces 93 is provided with a rounded edge 94 in the transition between the respective upper end surface 95 and support surface 93. The retaining clip 90 also has a front side 90a and a rear side 90b.

The coupling portion of the anchor 92 of each retaining clip 90 is in the shown embodiment formed as a displaced section comprising at least one side surface 96 and one lower end surface 97. Here, there are two side surfaces 96 arranged symmetrically to end in the lower end surface 97, and the displaced section has a front surface 98a, a rear surface 98b and also an inclined upper surface 99.

It should be noted that the function and configuration of the clamp clip 90 on the base plate of the hinge part of the frame 110 is substantially identical to that of the clamp clip on the base plate of the hinge part of the sheet 210, preferably also symmetric. However, variations are conceived.

Turning now to a description of the preferred embodiments of the pressure anchor with further reference to Figures 8 to 11, the pressure anchor 80 comprises an upper surface 85 configured to rest on a lower side of the respective cover element 1b, 2b, a guide portion 81 and a coupling portion 82.

The guide portion 81 of the pressure anchor 80 comprises two opposite guide surfaces 83 for interacting with the two opposite support surfaces 93 of the receiving portion 91 of the retaining clip 90. To facilitate the assembly process, each guide portion 81 may, as shown, be provided with a rounded bottom edge 81a. In addition, and in particular to improve retention of the pressure anchor 80 in the retaining clip 90, an overhang side wall portion 81b is also provided on both sides of the guide portion 81.

The coupling portion 82 comprises a tongue 88 and two legs 87 extending from the upper surface 85 of the pressure anchor 80 and located at a lower point 87a, so that a groove 89 is formed between the legs 87 and the tongue 88. The tongue 88 is in the embodiment shown, integrally formed with the guide portion 81 of the pressure anchor 80 and has a central opening 88a. The central opening 88a is present to facilitate the manufacturing process. The coupling between the coupling portion 82 of the pressure anchor 80 and the coupling portion of the anchor 92 of the clamping clip 90 will be described with particular reference to Figures 12 and 13, of which Figure 13 is a partial perspective view on a larger scale

As shown, the groove 89 of the coupling portion 82 of the pressure anchor 80 surrounds the coupling portion of the anchor 92 of the clamp clip 90 in the assembled condition shown in Fig. 13.

In the assembled condition, a rear surface 88b of the tongue 88 rests on the front surface 98a of the displaced section of the coupling portion of the anchor 92 of the fastening clip.

In the embodiment shown and described, the legs 87 of the pressure anchor 80 are preformed with a deflection in a direction away from the tongue 88.

In addition, the pressure anchor 80 comprises at least one elastic arm 86, here two elastic arms 86, connected in a transition portion 86a to the upper surface 85 of the pressure anchor 80 and having a free end portion 86b. As shown, the elastic arms 86 are in the shown embodiment located at a lower level than the upper surface 85.

When mounting the cover elements 1b, 2b to which the pressure anchors 80 have been connected, the pressure anchor 80 is inserted into the retaining clip 90 as indicated above and is moved down in the receiving portion 91. To achieve the releasable connection, the coupling portion 82 moves further down until the bottom of the slot 89 is located below the lower end surface 97 of the displacement section of the coupling portion of the anchor 92.

In the pressure connection, a gentle play is necessary to allow the groove 89 of the coupling portion 82 of the pressure anchor 80 to be guided over the coupling portion of the anchor 92. In addition, the inevitable tolerances on the hinge parts which include the clamping clip 90, and in the anchor 80 itself, make it advantageous to incorporate elastic means in the connection. Said elastic means can take any suitable form, but here the required play and any tolerance are accommodated by the presence of the elastic arms 86 on the upper surface 85 of the pressure anchor 80. Once the coupling portion 82 has been placed in contact with the coupling portion 92, the free end portions 86a of the elastic legs 86 come into contact with the respective upper end surface 95 of the retaining clip 90. When the elastic legs 86 are fold, the relative movement in turn will pull the legs 87 upwards and thus securing the support between the lower point 87a with the surface of the lower end 97 of the coupling portion of the anchor 92 of the clamping clip 90.

In the mounted condition, and in the case of a tensile force acting on the associated cover element, either as a mechanical force when the window is driven or due to the force of the wind, the pressure anchor configuration 80 will support the pressure coupling and will prevent an unjustified release of the clamping clip 90 from the hinge 10.

As a first measure to retain the pressure coupling, this is obtained by the fact that a tension load transmitted through the symmetrically arranged legs 87 results in substantially radial reaction forces having as a center a position in the displaced section of the coupling portion of the anchor 92 defined by the radius of curvature of the side surfaces 96 and the surface of the lower end 97 of the coupling portion of the anchor, thereby reducing the tension caused by the moment to an absolute minimum, leaving only the tension traction on legs 87 and lower point 87a.

An additional factor that contributes to enforcing the pressure coupling in the assembled condition is the configuration of the legs 87 with a preformed deviation to force the legs 87 as close as possible to the center of the pressure anchor 80. In this way, the line of respective action of a tensile force that acts substantially centrally on the pressure anchor 80 on one side and the reaction force between the legs 87 and the bottom point 87a with the coupling portion of the anchor 92 on the other part will be located near each other and therefore the resulting moment will be minimized. Optimally, the lines of action coincide.

Finally, the stability of the pressure anchor 80 in the clamping clip 90 and, in turn, the associated cover element 1b is provided by the provision of suitable support surfaces between the rear sides of the legs 87 and the front sides 90a of the clamp clip 90 and between the protruding portions of the side wall 81b of the guide portion 81 and the rear sides 90b of the clamp clip 90. In an optimal configuration, these bearing surfaces are all flat and parallel to each other; however, this can be difficult to obtain in practice due to, for example, practical considerations during the molding of the pressure anchor 80. However, sufficient stability is obtained if only opposite bearing surfaces are present.

If it is desirable for some reason to disassemble the hinge cover element, the release of the pressure coupling is particularly easy, since the pressure anchor 80, as in the embodiment shown, comprises a grip portion 84 formed in the ends of the legs 87 opposite the upper surface 85.

The connection between the pressure anchor 80 and the cover element 1b, 2b can, in principle, be carried out in any suitable manner.

For example, the connection is made by fastening the pressure anchor 80 to the cover element 1b, 2b as shown in Fig. 14, introducing a fastener 55 such as a screw or rivet into the opening 85a on the upper surface 85 of the pressure anchor 80. A rivet of this type would, for example, be a blind or pop rivet on the cover element 1b, 2b, further provided with an external thread for coupling the opening 85a.

In case the pressure anchor 80 is connected to the cover element 1b, 2b by means of an adhesive connection, this makes the presence of fastening means such as a screw or rivet redundant, and the pressure anchor 80 is, by so to speak, integral with the cover element as shown in, for example, Figs. 16 and 17. In addition, Figs. 16 and 17 also illustrate the pressure connection in the assembled state. Figure 17 is an exploded view of the pressure connection 70 seen through the cover element 1b.

It should be noted that the above description of preferred embodiments serves only as an example, and that one skilled in the art will know that numerous variations are possible without departing from the scope of the claims.
