Abstract

The measuring tool (1) is intended for preparation of a window lining (7) to fit between a window frame (4) and an inner wall (5), and comprises an angle element (2) and a ruler element (3). The angle element (2) has a first edge (21) adapted for abutment with the window frame (4) and a second edge (22) substantially perpendicular to the first edge (21), and including an arcuate track (23). The ruler element (3) has two side edges (31, 32) and two opposite end edges (34), and a pin (33) near one end edge, the pin (33) being slidingly accommodated in the arcuate track (23). The angle element (2) and the ruler element (3) are adapted to be rotated through a predefined angle interval defined by the ends (23a, 23b) of the track (23) in the angle element (2) to position at least one side edge (31) of the ruler element (3) and the second edge (22) of the angle element (2) at an angle with respect to each other.

Description

The present invention relates to a method for preparation of a window lining.

When installing windows in a fagade or a roof, it is desirable to make the transition between the window frame and the inner wall of the room of the building smooth and of a pleasant appearance. The transition is most often made up of a so-called window lining having dimensions to span the distance between the inner side of the window frame to the inner wall. In windows installed in a facade, i.e. substantially vertically, the lining is constituted basically of a box-shaped element having two side members, a top member and a bottom member, all being of a substantially rectangular shape and positioned at right angles to the window frame. The members are traditionally formed of panels or plates of such materials as plywood, gypsum or chipboard.

In windows mounted in an inclined roof, the geometry of the lining is more complicated. Basically, the side members are positioned at right angles to the window frame, as in facade windows, but the top member is most often substantially horizontal and the bottom member substantially vertical, or the top and bottom assume other angles with the window frame. A number of grounds for this particular design exist, one being that the horizontal top member allows for an increased influx of light, another that the vertical bottom member makes it possible to access the bottom window and optimise the space of the room. Thus, the top member and the bottom member form an angle other than 90° with the window frame, and the side members have a trapezoidal shape.

The adaptation of the shape of the members of the lining is relatively challenging, as the dimensions of each member rely on factors such as the inclination of the roof and the thickness of the wall. This is even more pronounced in new buildings or in buildings undergoing a complete renovation, in which the inner wall is not yet present, or to be replaced wholly or partly. In those cases, there might thus be no inner wall to start with, and the craftsman is faced with the further challenge of visualising the aperture in the inner wall before or during the installation of such inner wall.

In the prior art, a number of solutions have been proposed to facili- tate the installation and reduce the amount of manual adaptation and risk of incorrect installation. Examples are shown for instance in EP 17 399, EP 1 414 567 and EP 287 362. A measuring tool is devised in international publication No. WO 02/064335. This tool functions well but is limited to correct measurement and cutting-off of the finishing profile lists constituting the lining mouldings. A further and more recent example is described in EP 2 615 219 A1, in which an installation kit for linings for varying inclinations and wall thicknesses is provided.

Even though the arrangements disclosed in these documents facilitate the mounting and to some extent reduce the risk of incorrect installation, there is still a need for facilitated and fail-safe measurement and subsequent installation of window linings.

One further example of a prior art document is US 5915806 A which describes a measuring tool comprising a blade or ruler element rotatably attached to a head or angle element for measuring and marking wood or the like. However, the measuring tool of this document has a limited field of application.

With this background it is an object of the invention to provide a method for the mounting of a window lining, which renders the installation easy and uncomplicated.

This and further objects are met by a method for preparation of a window lining as indicated in claim 1.

Further embodiments and advantages are set forth in the dependent claim.

Referring to the Figures of the drawing, it is shown how a measuring tool 1 is formed in order to assist in the preparation of a window lining 7 to fit between a window frame 4 and an inner wall 5. The measuring tool 1 comprises two parts, viz. an angle element 2 having a first edge 21 adapted for abutment with the window frame 4 and a second edge 22 substantially perpendicular to the first edge 21, and including an arcuate track 23, and a ruler element 3 having two side edges 31,32 and two opposite end edges of which only outer free end edge 34 is indicated, and a pin 33 near one, inner end edge, the pin 33 being slidingly accommodated in the arcuate track 23.

As shown most clearly in Figs 11 and 12, the angle element 2 and the ruler element 3 are adapted to be rotated through a predefined angle interval defined by the ends 23a, 23b of the track 23 in the angle element to position at least one side edge 31 of the ruler element 3 and the second edge 22 of the angle element 2 at an angle with respect to each other. This makes it possible to use the measuring tool 1 in windows installed in roofs having various inclinations, for instance ranging from approximately 30 degrees (Fig. 12) to 60 degrees (Fig. 11). In the installation situation of Figs 1 to 10, the inclination is approximately 50 degrees. In one particular measuring tool, the measuring tool may also be utilized for preparation of window linings for installation with windows mounted in a fagade, i.e. substantially vertically. This is shown in Figs 13 and 14 and will be described in more detail below.

In Figs 1 to 5 it is shown how the measuring tool 1 is first utilized to mark the opening required for the window lining. Whereas is it relatively easy to define the size perpendicular to the window frame 4 as indicated by borderline 51 of the inner wall 5 in Fig. 1, it is a challenging task to define the upper limit of the opening to accommodate the window lining.

The measuring tool 1 is positioned with the first edge 21 of the angle element 2 in abutment with the window frame 4. The ruler element 3 is rotated to such an extent that the one side edge of the ruler element 3 is positioned in abutment with point P1 indicating the top of the borderline 51 of Fig. 1 and with ruler element 3 in a horizontal position, which is proved by suitable means such as a spirit level. The distance h from the top of the window frame 4 to the second edge 22 of the angle element 2 is measured, here by rule 6, and transferred to the inner wall 5 from point P1 to mark point P2 as shown in Figs 4 and 5. If desired, the measured distance h may be increased by an additional distance such as 10-20 mm in order to allow positioning of a finishing profile frame. The opening is cut by for instance sawing to provide borderlines 51 and 52.

The measuring tool 1 is also used in preparation of the window lining, in particular of the side lining panels 7 as shown in Figs 6 to 10.

In the measuring tool shown, the angle element 2 is provided with a first set of indicating means adapted for marking apertures on the lining panel 7 which are formed as protruding pins 24, 25 to mark corresponding holes 74, 75 in the lining panel 7.

Here, also the ruler element 3 is provided with a second set of indicating means adapted for marking apertures on the lining panel 7, namely as apertures 34a, 34b, 34c in the ruler element 3 for marking corresponding holes 73a, 73b, 73c in the lining panel 7.

Holes are drilled in the lining panels 7, the side lining panels 7 to the respective side being positioned on top of each other as shown in Figs 8 and 10. Subsequently, the lining panels 7 are cut along the lines 71 and 72 corresponding to the second edge 22 of the angle element 2 and the one side edge 31 of the ruler element 3.

The measuring tool 1 may in principle be formed in any suitable manner and in any material suitable for fulfilling the purpose. However, the measuring tool 1 is normally provided with the window panels and is possibly disposed of after use. Thus, an environmentally sustainable solution is preferred, allowing the measuring tool to be recycled. The angle element 2 may for instance comprise a front sheet 2a and a back sheet 2b of a wooden or plastic material and the ruler element 3, likewise of a wooden or plastic material, is inserted between the front sheet 2a and the back sheet 2b.

In order to ensure proper handling of the measuring tool, the front sheet 2a, the second sheet 2b and/or the ruler element 3 may comprise means for increasing the friction between them.

Referring eventually to the measuring tool of Figs 13 and 14, a straight track 29 is provided in connection with one end 23a of the arcuate track 23 in the angle element 2. The pin 33 of the ruler element 3 is accommodated in the straight track 29 to allow the ruler element 3 to assume a position in which one side edge 32 is flush with the second edge 22 of the angle element 2. In this manner, the one side edge 32 forms an extension of the second edge 22 of the angle element 2 and extends, in turn, at right angles to the first edge 21 of the angle element 2.

Also in this measuring tool and field of application, the ruler element 3 is provided with a second set of indicating means adapted for marking apertures on the lining panel 7, here in the form of apertures 34a, 34b, 34c in the ruler element 3. The translation of the pin 33 in the straight track 29 brings about a translation of the apertures 34a, 34b, 34c to ensure proper marking of the holes for fastening the lining panels.

In the alternative measuring tool shown in Figs 15 and 16, the angle element 2 is provided with at least one removable restraining element 40, which, when inserted in the angle element 2, defines a first angle interval of the track 23, and when removed from the angle element 2, defines a second angle interval of the track 23, the first angle interval being preferably a subinterval of the second angle interval. In the specific measuring tool, the restraining element comprises a pin 40, configured to limit the movement of the ruler element 3 in the track 23, when the pin 40 is inserted in an aperture 41 of the angle element 2, cf. the 30° range in Fig. 15 and the 20° range in Fig. 16, respectively.

The rationale underlying the alternative measuring tool resides in the fact that in certain installation situations, it may be advantageous to provide at least two different working positions of the measuring tool. The reason may be to ensure that there is sufficient material in the installation situation in question. As a general rule, lining panels are delivered with pre-defined dimensions. The choice of dimensions typically covers roof and inner wall inclinations in the range 30° to 60°. If the full depth of the product is not required (typically 300-400 mm), combined with a larger or smaller inclination, the restraining element may be removed thereby widening the working area of the inclination in question. With the restraining element in place, the range is limited to the most common inclinations falling within the typical range.

The manner of using the measuring tool according to the invention will be described in the following, in that a method for preparation of a window lining 7 to fit between a window frame 4 and an inner wall 5 is described with reference to the figures of the drawing, the method comprising the following sequence steps of: a) providing a window lining measuring tool 1 comprising an angle element 2 and a ruler element 3, b) providing a pin 33 near one end edge of the ruler element 3, said pin 33 being slidingly accommodated in a arcuate track 23 of the angle element 2, c) positioning a first edge 21 of the angle element in abutment with an inner side of the window frame, d) rotating the angle element 2 and the ruler element 3 through a predefined angle interval defined by ends 23a, 23b of the track 23 to position at least one side edge 31 of the ruler element 3 and a second edge 22, substantially perpendicular to the first edge 21, of the angle element 2 at an angle with respect to each other, and e) cutting a lining panel 7 along lines corresponding to the second edge 22 of the angle element 2 and the one side edge 31 of the ruler element 3, so that the lining panel 7 fits between the window frame 4 and the inner wall 5.

In the alternative measuring tool of Figs 15 and 16, the additional steps of providing a removable restraining element 40, and inserting the restraining element 40 in an aperture of the angle element 2, and defining with the position the restraining element 40 a first angle interval of the track 23 of the angle element 2 that the ruler element 3 can be rotated through. Optionally, the the restraining element 40 is removed, thereby defining a second angle interval of the track 23 that the ruler element 3 can be rotated through.

The invention should not be regarded as being limited to the embodiments described in the above. Various modifications and combinations may be carried out within the scope of the appended claims.
