    Title of Invention
    A refurbishment system for a roof window having a stationary frame and a set of adjustment bushings, and a method for refurbishing a window.
    Technical Field
    The present invention relates to a refurbishment system for a roof window having a stationary frame, a sash, and a set of hinges, in which the refurbishment system comprises a set of adjustment bushings. The invention furthermore relates to a method for refurbishing a window.
    Background Art
    Replacement of windows involves a substantial investment for a household due to the cost of the new window and the high cost of contractors for installing the new window and removing the old one.
    The reasons for replacing an old window can be numerous but often the decision to replace a window is made due to material decay or to gain the benefits provided by advances in window technology such as improved inlet of incident light, ventilation, or thermal insulation to provide an improved indoor climate.
    As the movable sash will often be worn at a faster rate than the frame due to the frequent movement when opening and closing the sash, the sash may often need replacement before the stationary frame. Furthermore, as advances within the field of window, e.g. improvements of the thermally insulating window pane, sash and window pane may become obsolete sooner than stationary frames.
    Consumers may be interested in being able to refurbish their window by simply replacing the sash of the old window and keeping the existing stationary frame, thereby prolonging the life of the window while minimizing replacement elements and installation materials, contractor work, and overall refurbishment costs.
    In case a replacement sash, or a refurbished sash, is to be re-installed in a stationary frame, it may however occur that the location of the hinges on
    DK 2017 70658 A1 the stationary frame is not optimal. The non-optimal positions are typically due to minor skewness, either in the position of the stationary frame in the roof structure, or in the sash frame itself.
    Thus, how to complete the refurbishment of a window remains a challenge.
    Summary of Invention
    It is therefore an object of the invention to provide a refurbishment system which allows for improvement of roof window properties, including the final visual appearance and functionality of an openable window that integrates an original stationary frame with a replacement sash. Furthermore, the refurbishment system should be easily installed in the roof structure.
    In a first aspect, this and further objects are met by a refurbishment system, of the kind mentioned in the introduction, which is furthermore characterised in comprising a set of adjustable bushings adapted to be connected to the frame members of the stationary frame in a mounted condition, and a replacement sash.
    The adjustable bushings provide multiple points where to adjust the distance between the stationary frame and the replacement sash in a manner making it possible to achieve maximal contact surface between these two elements in a mounted condition in closed position, this ensuring optimal sealing and aesthetic cohesion. Thus, the appearance and functionality of the openable window may be optimized at the refurbishment window installation stage. Consumers may be interested in being able to refurbish their window by simply replacing the sash of the old window and keeping the existing stationary frame, thereby prolonging the life of the window while minimizing contractor work and refurbishment costs. As the stationary frame of the window is maintained, this frame functions as an installation frame, thus rendering the mounting simple. The advantages are particularly present in roof windows, in which installation takes place in an inclined roof.
    In a presently preferred embodiment, which is particularly advantageous for a roof window in which the sash is movable between an open
    DK 2017 70658 A1 and a closed position, the refurbishment system comprises a stationary frame with a top frame member, a bottom frame member, and two side frame members defining a central opening, and, placed within the stationary frame, a sash with sash members carrying a pane.
    Frame and sash members are typically made of a rigid material, such as wood, polyurethane with a wooden core, polyvinyl chloride (PVC) or other polymers such as acrylonitrile butadiene styrene (ABS) or polyethylene (PE), metals such as aluminium, fiberglass, and combinations thereof, and have an elongated shape with at least one flat surface facilitating contact with other window elements. In this, whenever the term frame is used it is to be understood as including referring to a stationary frame carrying a sash. The terms stationary frame and frame are used interchangeably.
    Said sash is connected to the stationary frame side members by means of a set of two hinges, and is movable between an open and a closed position about a turning axis defined by the pivot hinges. Each hinge includes a frame hinge part with a set of spigots configured to be received in a first set of mounting holes in the side frame member.
    By a first set of mounting holes, it is meant the set of mounting holes that was originally used for mounting the roof window. These would typically be in the face of the stationary frame side members facing the central opening at a position that would best ensure stationary frame and sash contact in the closed position.
    In the context of the application, a closed position of the sash means a position in which the plane defined by the stationary frame and plane defined by the sash coincide, and form an angle of no more than a few degrees with each other. Similarly, an open position of the sash as used herein generally means a position in which the sash is tilted about the pivot hinge axis such that the stationary frame plane and the sash plane no longer coincide.
    In said preferred embodiment, the refurbishment system further comprises a set of adjustment bushings adapted to be received in a second set of mounting holes formed in the side frame members in a mounted condition.
    In the context of this application, adjustment bushings means bushings
    DK 2017 70658 A1 comprising an outer bushing part with an outer circumference fitting the second set of mounting holes in a rotational manner, and a substantially cylindrical internal opening in which an inner bushing part is received also in a rotational manner. Said inner bushing part has a substantially cylindrical outer circumference fitting in the internal opening of the outer bushing part.
    Furthermore, the inner bushing part has a through-going hole which is offset from the centre of the inner bushing part and is configured to receive a spigot of said hinge. Likewise, the internal opening of the outer part has an axis which is offset from the centre of the adjustment bushing, such that both the through-going hole in the inner bushing part, and the through-going hole in the outer bushing part are able to assume a plurality of positions by rotating the inner and/or outer bushing parts relative to the second mounting holes in the side frame members.
    An advantage of providing a system where bushings are adjustable to compensate for the skewness between the sash and the stationary members is it is possible to provide a makeover to an old window and thereby extend its lifetime. Furthermore, as the replacement sash members and features are not limited to the material or functionality of the original sash, they may provide new functionalities to be added to the window by enabling the use of various materials or construction types.
    In an embodiment of the invention, the adjustment bushings further comprise a first and a second end face, wherein at least one of said end faces has at least one groove.
    In another embodiment, two or more grooves span the internal opening on the adjustable bushing end face, and are aligned to each other forming sets of aligned grooves.
    By providing grooves on the end face of the adjustable bushings, these may receive a tool head, such as a screwdriver head, and enable the easy rotation of the inner bushing part or/and the outer bushing part relative to the second mounting holes during installation of the replacement sash.
    In some embodiments multiple groove sets provide arrangements allowing for rotation of the adjustment bushings using tool heads that require
    DK 2017 70658 A1 greater contact surface.
    The increased contact surface provides greater friction between the tool head and the end face of the adjustment bushing, resulting in a more effective transition of rotational force and better control on behalf of the user.
    In an embodiment of the invention the bushing part has a groove extending internally from an end face, creating an additional end face opening. In another embodiment said groove extends between the two of faces of the bushing part, creating two end face openings. In all of the considered embodiments, this groove is large enough to receive at least some of commonly employed tool shafts, but also not so large as to compromise structural integrity of the bushing. By providing such a groove, rotation is enabled to an even easier extent when the end face opening to the groove is accessible to said tool shaft in the mounted condition. In addition, provision of said end face opening and internal groove allows for the insertion of plyer-like tools that may assist in removing the adjustable bushings from the mounting holes in case of need.
    In an embodiment of the invention the substantially cylindrical throughgoing hole of the outer bushing part has at least one internal groove which interfaces with a circumferentially extending retention notch on the outer surface of the inner bushing part. This internal groove and retention notch operate to maintain the inner bushing part in place in the outer bushing part.
    Both during normal usage of the movable sash, which results in frequent movement when opening and closing the sash, and during installation, substantial mechanical stress on the adjustable bushings may ensue, causing the bushing parts to disassemble. By providing such a groove and retention notch, integrity of the adjustable bushings is ensured.
    In an embodiment at least one of the adjustment bushings further comprises flexible flanges adapted for engaging an adjustment bushing or the stationary frame to provide a snap lock. By providing a snap lock the process of mounting the bushings on the frame members may be facilitated such that it may be performed by a person with limited expertise.
    In an embodiment of the invention the outer bushing part further
    DK 2017 70658 A1 comprises an adhesive material arranged on the outer surface. This is preferably a slow drying adhesive material that will allow sufficient time for the installer to complete the installation before cementing the contacting parts. By adding an adhesive material arranged on the outer bushing part outer surface, increased assurance that the elected position of the adjustable bushings will not differ over time is obtained.
    In an embodiment of the invention at least one of the adjustment bushings are made from at least two separate pieces. This is particularly advantageous in the embodiments in which the substantially cylindrical through-going hole of the outer bushing part has at least one internal groove which interfaces with a circumferentially extending retention notch on the outer surface of the inner bushing part. In these embodiments, the bushing parts may not be adjoined by simply inserting the inner bushing part into the outer bushing part as the circumferentially extending retention notch would obstruct the end face opening. Thus, an embodiment contemplating adjustment bushings made from at least two pieces provides for a possible sequential bushing part assembly process and facilitates replacement sash mounting.
    In an embodiment of the invention at least one of the bushings are made from polyvinyl chloride (PVC). PVC allows the bushings to be made inexpensively without compromising durability and structural integrity. Other conceivable materials include stainless steel, aluminium, acrylonitrile butadiene styrene (ABS) and polyethylene (PE).
    In a further embodiment the refurbishment system further comprises at least one further component selected from the group comprising a frame part of a pivot hinge, a frame covering, a frame cladding, a top casing, a striking plate and insulation elements.
    The insulation element may be adapted to fit in any hollow cavity between the replacement sash and a stationary frame member. By providing insulation for any cavity formed between the sash members and the frame members, the thermal and/or sound conductive properties of the frame may be improved.
    In a second aspect of the invention, a method for refurbishing a
    DK 2017 70658 A1 window, in particular of a roof window installed in a roof structure, having a stationary frame and a sash, and a set of hinges is provided, comprising the steps of a) providing a refurbishment system as defined in the first aspect, b) preparing the roof window for refurbishment including removal of the sash, and c) mounting the refurbishment system to the stationary frame.
    By providing a method of this kind, the refurbishment is carried out in a number of simple and logical steps so as to allow a person with limited expertise to upgrade the window. Thus, making the method more cost efficient for the consumer.
    Other presently preferred embodiments and further advantages will be apparent from the following detailed description and the dependent claims.

    Description of Embodiments
    In the following, embodiments of the first and the second aspects will be described in further detail. The window will be referred to as a roof window, installed in an inclined roof surface. Directional terms such as “upper”, “lower”
    DK 2017 70658 A1 etc. relate to the position shown in the drawings. The invention is applicable to all types of windows, however.
    Fig. 1 shows a roof window 1 seen from the side of the roof window which faces the interior side of a building structure in which the roof window 1 is installed. The roof window shown in Fig. 1 comprises a frame 2 which is stationary when the roof window 1 is in a mounted condition. The stationary frame 2 has a top frame member 300, a bottom frame member 200 and two side frame members 100 defining a central opening, and a sash 3' carrying a pane 4. Each of the frame members 100, 200, 300 has an inner side facing the central opening.
    By the terms “exterior” and “interior”, mutually opposite sides of components of the roof window 1 are indicated, in a direction substantially perpendicular to the plane of the pane 4. The terms “outer” and “inner” are used to indicate for instance mutually opposite sides of the frame members 100, 200, 300, substantially in a direction parallel to the plane of the pane 4.
    In the type of roof window 1 shown in Fig. 1, the sash 3' is movably mounted in the stationary frame 2 by means of a set of hinges, here shown as pivot hinges 5 (cf. Figs 2 and 3), such that the sash 3' is movable about a substantially centrally located axis between an open and closed position relative to the stationary frame 2. Other types of hinges providing the desired movement pattern are conceivable as well, for instance so-called pantograph hinges including a linkage mechanism.
    The inner sides of the respective frame members 100, 200, 300 each comprises an exterior portion 102, 202, 302, which, when the window is in the closed position, is covered by the sash 3' and therefore not visible from the interior of the building structure, and an interior portion 101, 201, 301 which is not covered by the sash 3, when the window is in the closed position. Hence, the interior portion 101, 201, 301 is visible from the interior side of the building structure in both in the open and closed positions of the sash. In the shown embodiment, the exterior portions 102, 202, 302 of the inner sides of each of the frame members 100, 200, 300 are offset relative to the interior portions 101, 201, 301 to form a recess in which the sash 3' abuts when the window is in a
    DK 2017 70658 A1 closed position. Eventually, each of the stationary frame members 100, 200, 300 also has a bottom surface 103, 203, 303 which here, in a manner known perse, includes a groove adapted to accommodate a lining forming a transition between the roof window 1 and the roof structure.
    In order to renovate or refurbish the roof window 1 to extend the lifetime and/or improve the properties thereof, including for instance the appearance and insulating properties, a refurbishment system according to the invention is provided. In general, a refurbishment system comprises any parts of roof window, and substitute or additional parts. Here, a replacement sash is for instance indicated throughout by reference numeral 3' in the following in a particular embodiment of the invention. Other, not shown additional parts may include a set of capsules adapted to be connected to the frame members 100,
    200, 300 of the stationary frame 2 in the mounted condition. In further embodiments, which are not shown or described in detail, the refurbishment system comprises at least one further component selected from the group comprising a frame covering to replace existing frame cover 6, a frame cladding to replace existing frame cladding 7, a top casing to replace existing top casing 8, a striking plate to replace existing striking plate of the lock casing at the top of the window and insulation elements.
    Details of embodiments of the present inventive roof window refurbishment system and the method for refurbishing will be described in the following.
    In a first step, Fig. 2 shows the stationary frame 2 of the roof window 1, where the sash 3' has been dismounted to reveal the interior portions 101,
    201, 301 and the exterior portions 102, 202, 302 of the inner sides of the frame members 100, 200, 300. Also the frame part of the hinge 5 is shown in Fig. 2.
    Referring now to Figs 3 to 6, the refurbishment system of one embodiment to be applied to the roof window 1 comprises re-installing a sash in the stationary frame 2 following the mounting of an adjustment bushing 600 to receive fastening means of the frame part of the hinge 5. The sash could be a replacement sash (not shown) corresponding in principle to sash 3', or the sash 3' with or without a new sash part of the hinge. The present invention is
    DK 2017 70658 A1 in principle also applicable to mounting of a sash hinge part.
    As shown in Fig. 3, the hinge 5 is represented by its frame hinge part 51 having fastening means in the form of two spigots 52, 53 on the side facing the frame side member 100 in the mounted condition. The general configuration of such a hinge is well-known in the art and only parts relevant to the present invention will be described in detail. In the conventional roof window, e.g. the window before application of the refurbishment system, the spigots 52, 53 are received in mounting holes 152, 153 in the side frame member 100.
    In a first step in the refurbishment procedure of the present invention, a new set of mounting holes 162, 163 are arranged to receive a set of adjustment bushings 600. In a preferred embodiment, these mounting holes are essentially cylindrical in shape and are larger in diameter than and have centres coinciding with those of the first set of mounting holes 152, 153. In an embodiment of this application said mounting holes are configured so as to receive directly the adjustment bushings. In another embodiment the holes are configured to receive the adjustment bushings with a second set of bushings between the inner face of the second mounting holes and the outer circumference of the outer bushing part, thereby increasing contact and better securing the elements for increased functionality and durability.
    Referring now to Figs 5-6, and 9-11, the adjustable bushings comprise an outer bushing part 610 with an outer circumference fitting the second set of mounting holes 162, 163 in a rotational manner, and a substantially cylindrical internal opening 611 in which an inner bushing part 620 is received also in a rotational manner. Said inner bushing part has a substantially cylindrical outer circumference fitting in the internal opening of the outer bushing part.
    Said substantially cylindrical internal opening in said inner bushing part may be viewed as a through-going hole which is offset from the centre of the inner bushing part and is configured to receive a spigot 52, 53 of a frame hinge part 51. In addition, the internal opening 611 of the outer part has an axis which is offset from the centre of the adjustment bushing, such that both the throughgoing hole in the inner bushing part, and the through-going hole in the outer
    DK 2017 70658 A1 bushing part are able to assume an infinite number of positions by rotating the inner and/or outer bushing parts relative to the second mounting holes 162, 163 in the side frame members 100. The outer bushing part 610 may be rotated 360° independently of the inner bushing part 620 position. Since the internal opening 611 in the outer bushing part is offset, the position of the inner bushing part relative to the centre of the second mounting holes 162, 163 will be changed. Furthermore, the inner bushing part may be rotated 360° independently of the outer bushing part position. Since the internal opening in the inner bushing part 620 is offset, the position of the inner bushing part relative to the centre of the second mounting holes will be changed. This results in it being possible to combine rotation of the outer and inner bushing parts to position the inner bushing part internal opening at an infinity of positions within the range limited by the degree of offset of the internal openings from the centres of each bushing part. Furthermore, in the embodiment of the examples provided herein, two adjustable bushings 600 are used per each hinge 5, additional adjustment bushings being useful for increasing the number of adjustment points available and thus, by combining the adjustment of one and more adjustment bushings, the number of possible adjustment settings is multiplied. Internal opening positioning should be chosen so as to receive spigots 52, 53 of the frame hinge part 51 in a manner that best corrects skewness and best ensures contact between the replacement sash 3' and the stationary frame 100.
    In the context of this application, whenever the term internal opening is used, it is to be understood as including reference to an essentially cylindrical through-going hole, and visa-versa. The terms internal opening and throughgoing hole are used interchangeably.
    In an embodiment of the invention, the adjustment bushings further comprise two end faces and a groove on one of said end faces. Said groove is arranged to receive a tool head, such as a screwdriver head, which is used to transmit rotational force to the adjustment bushing through the placement of such a tool in said groove. In an embodiment of the invention, the adjustment bushing end face comprises several grooves. In a preferred embodiment said
    DK 2017 70658 A1 several grooves are aligned in pairs across the internal opening of the adjustment bushing, forming sets of aligned grooves (Figs. 7, 7a & 7b), thereby increasing the groove surface available, and thus enabling better transition of rotational force.
    In some embodiments multiple groove sets provide arrangements allowing for rotation of the adjustment bushings using tool heads that require greater contact surface.
    The increased contact surface provides greater friction between the tool head and the end face of the adjustment bushing, resulting in a more effective transition of rotational force and better control on behalf of the user.
    In an embodiment of the invention, said groove has two equal surfaces 630a and forms an angular cross-section (Figs. 7, 7a, 9 & 10). In another embodiment of the invention, said groove has three surfaces 630b, one bottom face and two equal opposed side surfaces, thus forming an angular crosssection (Figs. 7, 7b, 9 &10). In a preferred embodiment of the present invention, an end face comprises a variety of two-surface and three-surface grooves, that align to each other with matching number of surfaces (Figs. 7-9). In another embodiment of the present invention, said two surfaces have a curved cross-section forming a continuous arc.
    In the embodiment of Figs. 8,9 & 10, that show a side end view and perspective views of adjustment bushings and bushing parts respectively, bushing parts comprise a groove 640 extending internally from the end face, thus creating an additional end face opening on the opposing end face to that carrying grooves 630. This groove 640 may be of many types, but is preferentially formed by 4 faces; a bottom face, two equal opposing side faces and one internal end face, and thus forming an angular cross-section. The groove 640 shown on outer bushing part 610 and the groove 640 shown in inner bushing part 620 in Fig. 10 are rather similar. Elements having the same or analogous function are denoted by the same reference numerals.
    In another embodiment of the present invention, groove 640 extends the full distance between the two bushing part end faces. This feature results in an additional end face opening and increases accessibility to groove 640
    DK 2017 70658 A1 even in installed condition, thus making rotational adjustment of the adjustable bushings even easier and the use of an increased selection of tools possible. Caution must be taken, however, for the inclusion of said fully extending groove 640 not to compromise structural integrity of the bushing. In this situation, alternative, stronger materials may be desirable for the manufacturing of the adjustable bushings, such as more resistant polymers, metals, or fibres.
    In an embodiment of the present invention, the outer bushing part 610 further comprises an adhesive material arranged on the outer surface. By adding an adhesive material arranged on the outer bushing part outer surface, increased assurance that the elected position of the adjustable bushings will not differ over time is obtained. Adhesive material includes all possible types of adhesive, such as, but not limited to; drying adhesives, hot, pressure-sensitive, contact, reactive, natural or synthetic adhesives. In the context of this application, adhesive material present on the outer surface of the outer bushing part also includes textures and contours arranged so as to increase the retention of said bushing part in mounting holes. It is also conceivable to include means affecting the contact between the outer and inner bushing parts. Such means may comprise a seal located in one of the facing recesses of the bushing parts, a coating, element providing on or both bushing parts with resilient properties etc.
    In an embodiment of the invention at least one of the adjustment bushings are made from at least two separate pieces. This is particularly advantageous in the embodiments in which the substantially cylindrical through-going hole of the outer bushing part has at least one internal groove which interfaces with a circumferentially extending retention notch on the outer surface of the inner bushing part. It is desirable, in the context of the present application, to provide means of adjoining said two pieces of bushing parts so that the fully-formed bushing part may fulfil its function in the adjustable bushing.
    According to the invention the method of refurbishing a window by replacing a sash should be simple, in such a way that it may be possible to perform by a person not having much expertise in window installation. Hence
    DK 2017 70658 A1 the invention both provides a method for refurbishing a roof window installed in a roof structure and having a stationary frame and an existing sash, in which a step of preparing the roof window for refurbishment is included.
    In the above, a few embodiments of a refurbished roof window by means of a refurbishment system to be connected to the stationary frame have been described. It is to be understood that several modifications and combinations may be carried out. For instance, regarding the adjustable bushings shown and described, it is to be understood that adjustable bushings may also be used on other windows than the centre-hung pivotable roof window, and that their shape and design may be varied accordingly. Likewise, different combinations of features mentioned as alternatives above are also covered by the invention as defined by the scope of the claims.
