Definitions

  • the present invention relates to a kit comprising a tool and a vapour barrier collar including mounting means according to the preamble of claim 1.
  • vapour barrier collar is arranged along the circumference of the window frame and connected to the vapour barrier membrane of the roof structure such that insulation is protected from moisture from the interior.
  • a vapour barrier collar is disclosed in Applicant's European patents Nos 2 243 893 B1 and 2 711 480 B1 , which disclose a kit according to the preamble of claim 1, according to which the collar is arranged to comprise circumferentially joined sheet elements.
  • the vapour barrier collar is arranged around the aperture of the roof window by mounting means present along the edges of the vapour barrier collar.
  • the mounting takes place by inserting the mounting means of the vapour barrier collar in a circumferential groove of the window frame.
  • the mounting means are typically in the form of a number of individual "press-in pieces", or a coherent strip, of a relatively stiffer material compared to the vapour barrier collar material, the press-in pieces being distributed with intervals along the edge of the collar that is to be inserted into the groove of the building structure.
  • the vapour barrier collar material is made from a substantially incompressible material, typically formed as a film or foil of a plastic material such as polyethylene, with a thickness of about 0.2 mm and having a low permeability.
  • a tool is typically provided for assisting in the arrangement of the vapour barrier collar within the groove in the window frame.
  • the known tool is formed as a cap having a tooltip which has rounded edges. This is arranged to be pushed and slid to arrange the mounting means of the vapour barrier in the groove of the window frame. Even though such a tool has proven to function well and is generally used by installers, it requires some caution in use. This is due to the fact that there may be friction between the material of the vapour barrier collar and the tooltip during installation, which leads to the material being pushed as the sliding action occurs.
  • this may form an accumulation of material of the vapour barrier collar at the corners of the building structure, following which the installation of the collar needs to be restarted. It may also cause weakening or even rupture of the vapour barrier collar material. This in turn may lead to decreased quality, longer installation times, or in worst case, costly damages due to leakage. Thus, there is a need for an improved solution of an installation tool.
  • kits of the kind mentioned in the introduction which is furthermore characterised by the features of the characterising portion of claim 1.
  • the installation of the vapour barrier collar is made efficient and reliable. Since the material of the vapour barrier collar will be subjected to a rolling action and the mounting means so to say rolled into position in the groove, any unnecessary friction in the longitudinal direction is avoided and as a consequence, material stack-up for instance in the corners of the window frame is prevented.
  • the provision of two roller wheels connected to each other by a snap hook leg and a receiving aperture provides for a mechanically simple, yet reliable structure, which is furthermore easy to assemble and disassemble.
  • each roller wheel of the roller wheel set is provided with a cog-like outer face, wherein cogs are arranged across a substantial part of the width of the roller wheel.
  • cog-like is to be understood as encompassing any teethed surfaces, including configurations of arbitrary tyre tread patterns.
  • cogs should be interpreted in this broad sense. By providing cogs, it allows the roller wheel to sufficiently hold down the substantially incompressible material of the vapour barrier collar and move over the vapour barrier material without sliding.
  • the cogs may be arranged at an angle at least partially across the width of the roller wheel, or perpendicular to a linear rolling direction of the roller wheel in the longitudinal direction of the tool, and the cogs may have a pre-defined maximum depth. These measures are preferable to prevent any damage to the material of the vapour barrier collar. Therefore, the cogs may not be too sharp at the edges. The sharpness may be varying, since the material of the vapour barrier collar may vary depending on the current type of installation. By providing a specific depth to the cogs, it is ensured that the vapour barrier collar will not be damaged when the installation personnel applies pressure to the roller wheel. If the cogs are too deep, an excessively applied pressure may perforate the material of the vapour barrier collar. Thus, a correctly determined cog depth may prevent damage and increase quality of the installation.
  • the other roller wheel comprises a socket portion with guiding means for said at least one snap hook leg and cooperating with the opening in the protruding front portion.
  • roller wheels are connected to the head element at a wheel centre such that the roller wheels are confined substantially at extensions of the contours of the head element of the tool. This provides for improved usage and storage properties.
  • each roller wheel of the roller wheel set may have a width-to-diameter ratio being about 1:1. Preferably 1:2 but not more than 1:3. In this way, it may be ensured that the width is not too narrow. If the width of the roller wheel is narrow, the wheel may inadvertently act as a cutting tool and perforate the material of the vapour barrier collar. Therefore, it may be ensured that the roller wheel has a width so that the roller is not too sharp at its edge.
  • the operating means of the head element comprise an oblong cavity and an opening towards the ambient at the rear end of the head element in connection with said cavity, which is able to receive at least partially and retain an oblong body element. While the dimension of the operating means in the longitudinal direction may be of a size permitting the operating means to be used as handle in itself, the configuration with an oblong body element renders the installation process more comfortable.
  • an accessory equipment is arranged in connection with the head element of the tool and optionally the body element.
  • the body element, or the accessory equipment may be a pencil, a measurement stick, a multi-tool, a knife, a tucker, an adapter element, or the like.
  • the tool may constitute a multi-purpose tool and fulfil several functions during installation of the vapour barrier collar and/or other building components, and further time may be saved by reducing the installation personnel's effort.
  • "oblong" means that the dimension of the operating means in a longitudinal direction is at least slightly larger than the dimension of the operating means in a transversal direction.
  • oblong means that the dimension of the cavity in a longitudinal direction is at least slightly larger than the dimension of the cavity in a transversal direction.
  • the accessory equipment may be arranged at the body element, be part of the body element, or be the body element.
  • the body element alternatively the accessory equipment, may serve as a handle as it prolongs or extends the operating means of the tool when partly contained in the cavity. This provides for a tool that is easy to operate and fits well into the installer's hand. As the tool can be removed from the body element and/or accessory equipment when not in use, the tool is very little space consuming due to its compact structure.
  • kit forms part of a kit including also at least a vapour barrier collar to be used in the installation of a roof window.
  • a perspective, partial sectional view of a vapour barrier collar generally designated 10 is shown in connection with a roof window 1 having a window frame 2 mounted in an aperture in a roof structure.
  • the vapour barrier collar 10 comprises a number of sheet elements of which the bottom sheet element 11 is shown. For example, two side sheet elements, a top sheet element and the bottom sheet element 11 may be provided.
  • the roof window 1 also comprises a sash 3 in which a pane 4 is encased.
  • the window frame 2 is built into a roof structure of any suitable configuration, here represented by battens 7, but may also comprise rafters, underroof, insulation and further details not described.
  • a lining panel 5 is configured to form a transition between the window frame 2 and an inner wall of a room of the building in which the roof window 1 is installed, on the interior side of the vapour barrier collar 10.
  • the roof window 1 is substantially rectangular, and the window frame 2 comprises four mutually orthogonal frame members; each of these members will be referred to only as "window frame 2".
  • the vapour barrier collar 10 is intended to be connected to a vapour barrier membrane 8 of an underroof forming part of the overall roof structure, here by a tape 9 at an interior edge 11a of the bottom sheet element 11 of the vapour barrier collar 10.
  • the vapour barrier collar 10 is, in the example shown, substantially symmetrical about both a longitudinal central axis and a lateral central axis. Due to this symmetry, it is understood that the description applies for all sections of the vapour barrier collar 10 though only one section of the vapour barrier collar 10 is described.
  • the vapour barrier collar is composed of four trapezoidal sheet elements 11 welded together to form a vapour barrier collar having the shape of a frustum of a pyramid. It is to be understood that the invention described is equally applicable to a vapour barrier collar having the shape shown in the above-mentioned EP 0 994 991 .
  • the sheet elements 11 are mutually joined together in joints extending along end edges to form a collar including a coherent rim along first edges of the respective sheet elements.
  • the material of the vapour barrier collar 10 is a substantially incompressible plastic material, formed as a film or foil of a suitable plastic material, for instance of polyethylene.
  • the vapour barrier collar 10 has a thickness of about 0.2 mm and has a low permeability such that the insulation is protected from moisture formed on the warmer inside of the building.
  • mounting means 12 of the vapour barrier collar 10 are successively introduced into a circumferential groove 21 of the window frame 2 by applying a pressure on the mounting means 12 by the aid of an inventive tool to be described below.
  • the configuration of the respective sections of the vapour barrier collar 10 is represented by the bottom sheet element 11, in which a sheet of a suitable foil material is provided with the mounting means 12 at an exterior edge 11b, opposite the interior edge 11a.
  • the mounting means 12 comprise an anchor element 12a of a suitable material, such as a relatively rigid plastic material, which is fastened to the foil of the bottom sheet element 11 by for instance welding.
  • sealing elements 12b and 12c are provided, typically of a resilient foam material.
  • a height HM of the mounting means 12 is defined as the distance substantially between opposing outer edges of the sealing elements 12b and 12c.
  • the height HM is chosen such that a reliable fit is obtained when the vapour barrier collar 10 is brought into connection with the groove 21 of the window frame 2.
  • Typical measurements of the groove 21 and hence of the height HM are about 12.5 mm. This will also accommodate lining panels 5 made of gypsum or other board materials of standard thickness.
  • a first embodiment of a tool 50 of a kit according to the present invention for use in the installation, or mounting, of a vapour barrier will be described in further detail.
  • the tool 50 is thus applicable for use in mounting a vapour barrier of any suitable configuration, for instance in the form of a vapour barrier collar as described above whether formed by 1) four trapezoidal sheet elements, 2) two trapezoidal sheet elements and two rectangular sheet elements as the prior art vapour barrier collar described in EP 0 994 991 , or 3) any other shape.
  • the tool 50 comprises a head element 51 including a front end 55 at which insertion means 52 for introducing the mounting means 12 of the vapour barrier collar 10 into the groove 21 are formed.
  • the head element 51 of the tool 50 is furthermore provided with operating means 54 for operating the tool 50 when arranging the mounting means 12 into the groove 21 of the window frame 2.
  • the head element 51 of the tool 50 has a rear end 59, which in principle could form the rear end of the entire tool 50.
  • a longitudinal direction LX is defined as extending through the front end 55 and the rear end 59.
  • the tool 50 also comprises a body element 60, cf. Fig. 6 , which has a second rear end 65 opposite the front end 55 of the head element 51 of the tool 50.
  • the overall length of the tool 50 in the embodiment shown, between the second rear end 65 and front end 55 may range between 100 and 300 mm to ensure ease of operability of the tool 50 while still being able to be stored conveniently between uses.
  • the length of the head element 51 between the front end 55 and the rear end 59 is chosen such that the operating means 54 of the tool 50 are oblong so as to serve as a handle in itself by providing a sufficiently comfortable grip on the operating means 54.
  • the total length of the head element 51 typically amounts to 50 to 100 mm, here about 75 mm.
  • the head element 51 of the tool 50 includes a clip 58.
  • the clip may provide a storage option when not in use, for instance to secure the tool onto a piece of clothing.
  • the clip 58 may also serve as a rest for the installer's index finger.
  • the head element 51 of the shown embodiment of the tool 50 furthermore comprises an oblong cavity 56 and an opening 57 towards the ambient in connection with the cavity 56, at the rear end 59.
  • the cavity 56 is able to receive at least partially and retain a correspondingly oblong object, here the body element 60, and/or an accessory equipment.
  • the dimension of the cavity 56 in a longitudinal direction is at least slightly larger than the dimension of the cavity 56 in a transversal direction.
  • the dimension of the cavity 56 in a longitudinal direction is approximately 1.5 times larger than the dimension of the cavity 56 in a transversal direction.
  • the body element 60 is arranged to be inserted in the cavity 56.
  • the cavity 56 is provided with longitudinal ridges 56a to provide at the same time easy insertion into and a suitable resistance against inadvertent withdrawal from the cavity 56 of the body element, or of accessory equipment to be described below.
  • the body element 60 may thus be serving as a handle as it prolongs, or extends, the operating means 54 of the tool 50.
  • Different cross-sectional shapes may be envisaged besides rectangular, for instance square, oval, elliptic or round.
  • the body element 60 here comprises a carpenter's pencil with a front portion 60a configured to form a tip of the carpenter's pencil to be sharpened as desired.
  • the insertion means 52 comprise a roller wheel set 53 including at least one roller wheel for applying a pressure and rolling on the mounting means 12 of the sheet elements, including bottom sheet element 11 as shown in Fig. 14 , of the vapour barrier collar 10 to arrange the mounting means 12 into the groove 21 of the window frame 2 of the roof window.
  • the roller wheel set 53 is connected to the operating means 54 of the head element 51 at a wheel centre 53.1 at the front end 55 of the tool 50. Two wheels 53a and 53b are provided.
  • the insertion means 52 in the form of the roller wheel set 53 53 here the two wheels 53a, 53b, provided at the proximity of the front end 55 has a width and a diameter and are arranged so that a rotation of the roller wheels 53a, 53b in the longitudinal direction LX of the tool 50 is admitted so that the mounting means 12 are arranged in the groove 21 by rolling the rolling wheels in the longitudinal direction LX of the tool 50 and along the respective length direction of the individual members of the window frame 2.
  • Each roller wheel 53a, 53b has a pre-defined diameter DW and a width WW. The diameter may relate to the width as a ratio in order to ensure that the rollers do not damage the vapour barrier material. If the roller wheel is too narrow, the roller wheel may cut through the material of the vapour barrier collar.
  • the width of the roller wheel set at the insertion means is slightly smaller than the distance between the two sidewalls of the groove. Typical values of the width of the tool may be 75-95% of the size of the mounting means of the vapour barrier collar, and 80-90% of the groove in the building component.
  • a total width WT of the roller wheels 53a, 53b is chosen in accordance with the expected width of the corresponding groove 21 in which the mounting means 12 of the vapour barrier collar 10 are to be arranged.
  • the width WW of each roller wheel 53a, 53b is sufficiently wide to not cause damage onto the vapour barrier collar 10.
  • the roller wheel 53; 53a, 53b may have a width-to-diameter ratio of between 1:1 to 1:3, meaning that the width WW and the diameter DW may be equally big, but also that the width cannot be too narrow. If the width is too narrow, the applied pressure during installation may cause perforation in the barrier material.
  • the two roller wheels 53a, 53b are arranged so that they share a centre of rotation.
  • the width of the insertion means 52 at the front end 55 of the tool 50 substantially corresponding to the total width WT of the roller wheels 53a, 53b at either side of the protruding front portion 51.1, it is expedient that it is slightly smaller than the distance between the two side walls of the groove 21 into which the mounting means of the vapour barrier collar is to be inserted.
  • the width of the insertion means 52 at the front end 55 of the tool 50 generally preferably lies between 10 and 12 mm, depending on the width of the groove 21.
  • the width of the insertion means 52 should be chosen such that the tool 50 may be moved along the groove 21 in the window frame 2, however without catching against the side walls of the groove 21.
  • the operating means 54 of the head element 51 of the tool comprises a narrow front portion 54a having a width substantially corresponding to or slightly smaller than the total width WT, and a wider rear portion 54b.
  • the width of the wider rear portion 54b may exceed the width of the groove 21 such that only the narrow front portion 54a and the insertion means 52 of the tool 50 move within the groove 21.
  • roller wheels 53a, 53b are shown in more detail. It emerges that a circumferential face of the roller wheels 53a, 53b has a cog-like structure to provide a teethed surface, or tyre tread pattern. Any suitable configuration providing a rolling action of the tool 50 against the surface of the vapour barrier collar 10 aimed at may in principle be chosen. In the following the cog-like structure is referred to as cogs 53.2.
  • the cogs 53.2 are arranged to improve the grip towards the vapour barrier material and subsequently during installation; the roller wheels 53a, 53b ensure an improved installation since the tool 50 does not push the vapour barrier material in front of the tool (or below the tool 50, in case the tool 50 is rolled backwards). In this way, stack-up of the material is prevented.
  • the movement of the tool 50 in the groove 21 may in principle be carried out either forwards or backwards in the longitudinal direction LX.
  • the cogs 53.2 may be arranged across at least part of the width of the roller wheel, preferably across at least 80% of the width.
  • the cogs may as shown have a blunt tip. This may ensure that the cog edges do not perforate the vapour barrier material. However, the cogs may be substantially sharp.
  • the cogs 53.2 are shallow. This means that they have a major diameter-to-minor diameter ratio close to 1:1.
  • the shallowness of the cog may ensure that the applied pressure onto the roller wheel 53 during installation does not cause perforations in the vapour barrier material.
  • the cogs may be arranged at an angle relative to the rolling direction across the width of the roller wheel 53a, 53b, or be provided with angled sections, either outwards or inwards relative to the axial direction of the roller wheel/s. The angle, if any, may be determined based on the best grip provided to the mounting means.
  • the circumferential surface of the roller wheel may be provided with additional gripping means.
  • the cogs of the roller wheel may have a pre-defined maximum depth of 0.1 to 5 mm, preferably 1 to 2 mm.
  • the short depth ensures that the cogs does not receive too much pressure and transfers it onto the vapour barrier material. A too high pressure may cause a cog to perforate the vapour barrier material.
  • the two roller wheels 53a, 53b are arranged at a respective side of the protruding front portion 51.1 of the head element 51 and are connected to each other by means of two snap hook legs 53.3 on one roller wheel 53a interacting with a counterpart receiving aperture 53.4 in the other roller wheel 53b via an opening 51.2 in the protruding front portion 51.1.
  • the other roller wheel 53b is here provided with a socket portion 53.5 with guiding means for the snap hook legs 53.3 and cooperates with the opening 51.2 in the protruding front portion 51.1 such that a smooth rolling movement is facilitated.
  • the wheels 53a, 53b are easily assembled during manufacture. They may also be easily disassembled by releasing the snap engagement, for instance in order to re-use the tool as a holder/extender for a carpenter's pencil.
  • each roller wheel 53a, 53b is connected to the head element 51 at the wheel centre 53.1 such that the roller wheels are confined substantially at extensions of the contours of the head element 51 of the tool 50, i.e. within a straight line continuing from the contour of an under side 51.3 of the head element 51 and a curved line continuing from the contour of a curved upper side 51.4. Only a portion of the roller wheels 53a, 53b protrudes beyond to ensure correct contact between the insertion means 52 and the substantially incompressible material of the vapour barrier collar 10 in use of the tool 50.
  • a second embodiment shown in Fig. 7 comprises an accessory equipment 161.
  • Elements of the second embodiment having the same or analogous function as elements of the first embodiment carry the same reference numerals to which 100 has been added. Only differences will be described in detail.
  • the accessory equipment 161 of the second embodiment is accommodated in the cavity (not visible in Fig. 7 ) of the head element 151 of tool 150. In the position shown in Fig. 7 , the accessory equipment 161 is partially withdrawn from the head element 151. In its fully inserted position, a rear end 169 of the accessory equipment 161 is substantially flush with the rear end 159 of the head element 151.
  • Securing means 170 are provided to safely engage the accessory equipment 161 with the head element 151 of the tool 150.

  • the accessory equipment 361 may be used as a tucker, i.e. an assisting tool in the tucking-in of insulation material at the outer circumference of the window frame 2 of the roof window 1. This is particularly useful in the case of strips of insulating material to be tucked into narrow spaces surrounding a building component.
  • the accessory equipment 361 of the tool 350 of this embodiment may also be used in other fields of application.
  • the tool 350 thus constitutes a multi-purpose tool, having insertion means 352 on the head element 351 for use in arranging the vapour barrier collar in the groove in the window frame member, but also a tucker tool provided by the auxiliary equipment 361 and configured to be used independently from the insertion means 352. Since the tucker tool is located at the opposite end of the tool 350, it may in fact not be used at the same time as the insertion means.
  • Fig. 13 shows a variant of the tool of the fourth embodiment. Elements having the same or analogous function as in the fourth embodiment are denoted by the same reference numerals to which ⁇ has been added.
  • the tool 350' is provided with insertion means 352' of a rounded, fixed shape. Also tool 350' functions as a multi-purpose tool.
  • the tool of any of the above embodiments may be re-used a number of times.
  • Re-use may include installation of further vapour barrier collars, functioning as a holder/extender of a carpenter's pencil, and/or as a receiver or holder/extender of auxiliary equipment.
  • the parts of the tool may be disposed of in dependence on the material chosen, typically comprising hard plastic.
