Definitions

  • the invention relates to a lifting tool for mounting and dismounting the sash of a roof window in an inclined roof, the lifting tool comprising to support stands adapted for being arranged on the roof on opposite sides of an installed window frame of the roof window, each support stand comprising a support base, a support leg, and an angle bar which together forms a triangle with a connection point at each corner; a cross bar which can be releasably attached between the support stands; and a winch which can by mounted on the cross bar.
  • the invention further relates to a method for mounting and dismounting the sash of the roof window in an inclined roof.
  • Mounting and dismounting roof windows are often associated with heavy lifting as the processes include lifting the sash a window pane into position or out of the window frame. Such lifting is usually performed manually by the workers installing or renovating the roof window, which may, in the long run, result in work injuries. Furthermore, this work is performed under difficult conditions where both the inclination of the roof and wind and weather may make the work process difficult.
  • the lifting tool is composed of a frame with two support stands which are placed on opposite sides of the installed window frame, so that a winch arranged on a cross bar of the frame can lift the window pane and the sash by a suction assembly.
  • the components of the frame can be adjusted telescopically in their lengths.
  • the telescopic adjustment enables the lifting tool to be adapted to different kinds of windows and roof constructions, it also makes the lifting impractical in that when it is put in position and dismantled, it is required that the lifting tool is assembled/disassembled at every single telescopic connection, which is time consuming and delays the work for the worker.
  • a further problem with this way of assembling and disassembling the lifting tool is that the lifting tool, when it disassembled, is separated into many separate parts, which makes it difficult for the worker to keep track of every single part.
  • this is achieved by a lifting tool as described in the background section, wherein two of the connection points between the support base, the support leg, and the angle bar of each support stand is pivotable and the third connection point is releasable, when the lifting tool is not in use, so that the lifting tool can be folded together.
  • the advantage of this is that the lifting tool can be disassembled by removing the cross bar from the support stands and the support stands are separated at the releasable connection point, thereby allowing the support stands to be folded together about the two pivotable connection points.
  • the support stands thereby remain in one easily manageable piece in a folded condition.
  • the entire lifting tool can therefore be transported in fewer parts than the lifting tools disclosed in the prior art. This is particularly advantageous when the lifting tool is to be assembled on the roof, as transport from the ground and up to the roof construction often involves manoeuvring narrow passages such as scaffolding, where the lifting tool of the prior art will be problematic getting through with.
  • Each support stand is constructed such that the support base is adapted to abut against the roof construction adjacent and substantially parallel to a respective one of the window frame's two side frame elements, so that the roof construction provides a resting surface for the lifting tool.
  • the support leg extends substantially vertically from the support base, whereby the weight of the sash and window pane is transferred optimally when the lifting tool is used.
  • connection points of each support stand is displaceable so that the support stand can be adjusted to the inclination of the roof.
  • the displaceable connection point can be provided by making one of the pivotable connection points displaceable under assembly of the lifting tool, e.g. by arranging the pivotable connection point on slide shoe which can be locked in position during the assembled condition of the lifting tool.
  • the displaceable connection point by allowing the releasable connection point to be displaceable along the length of one of two of the support base, the support leg, and the angle bar which are connected by the releasable connection point.
  • the displaceable connection point is provided by an elongate slot in either the support base, the support leg, and the angle bar so that the releasable connection point can be positioned along the length of the elongate slot during assembly of the support stands.
  • the displaceable connection point is provided by a row of connection holes arranged in either the support base, the support leg, and the angle bar so that the releasable connection point can be positioned in the connection hole best suited for the inclination of the roof.
  • each support stand may be adjusted more precisely for the inclination of the roof, as the elongate slot allows placement of the releasable connection point along the entire length of the elongate slot.
  • the disadvantage of using an elongate slot is that both support stands must be adjusted precisely in order to avoid the lifting being crooked. To facilitate this, the elongate slot on each support stand can be provided with markings along the length of the elongate slot, so that correct positioning of the releasable connection point is made simpler.
  • each hole may be provided with markings showing the interval of roof inclinations the respective hole is suited for.
  • the lifting tool further comprises a mounting strap which can be spanned between the support bases.
  • a mounting strap which can be spanned between the support bases it is prevented that the two support bases slip away from each other.
  • the mounting strap is adapted to extend along the upper side of the top element of the window frame so that the mounting strop also prevents the lifting tool from slipping downwards on the inclined tool during assembly and/or during use.
  • the length of the mounting strap is adjustable so that it can be adapted to the width of the window frame.
  • the mounting strap may be replaced by a rigid rod or beam, if it is also needed the prevent the support bases from slipping towards each other. In assembled condition, this is however usually prevented the side elements of the window frame, for which reason a lighter and more manageable mounting strap is preferred over a rigid bar/beam.
  • At least one of, preferably both, support bases comprise a batten hook adapted to grip a batten close to the window.
  • a batten hook adapted to grip a batten close to the window.
  • the cross bar is provided with two connection element which are adapted to connect the support stands to the cross bar and are displaceable along the length of the cross bar, so that the distance between the support stands can be adjusted according to the width of the window frame.
  • each connection element comprises a cavity with an internal shape corresponding to the external shape of the support legs so that the connection elements can grip around the support legs.
  • the connection elements are separate elements displaceable along the length of the cross bar so that the distance between the support stands can be adjusted in accordance to the width of the window.
  • the invention in a second aspect, relates to use of the lifting tool of the first aspect of the invention to mount and dismount a window pane and a sash of a roof window in an inclined roof construction.
  • the invention in a third aspect, relates to a method for mounting or dismounting a window pane and a sash into/out of a roof window in an inclined roof with a lifting tool, said method comprising the steps of arranging a support stand parallel to each of the side elements of the window frame, assembling each support stand by connecting the third connection point which is releasable, connecting the cross bar to the support stands, mounting the winch on the cross bar, attaching the window pane and the sash to the winch, and mounting/dismounting the window pane and the sash into/out of the window frame.
  • the method further comprises the step of arranging the displaceable connection point of each support stand so that the support legs are substantially vertical. This ensures that the weight from the window frame and the sash is transferred optimally from the support leg to the support bases, and that the connection point between these two components are not subjected to unnecessary strain during use of the lifting tool.
  • the method further comprises the step of spanning the mounting strap between the support bases along the upper side of a top element of the window frame. In a preferred embodiment, this step further comprises adjusting the length of the mounting strap to the width of the window.
  • the method further comprises the step of attaching the batten hooks to a nearby batten of the roof construction.
  • the lifting tool is secured so that it will remain in place and steady, even when it is carrying the full weight of the window pane and the sash of the window.
  • This step can further comprise exposing a batten in the roof construction by removing a roof covering, such as tile or roof plates.
  • Fig. 1 shows a lifting tool 1 of the invention.
  • the lifting tool 1 comprises two support stands 2 which together carries a cross bar 6 adapted for, in an assembled condition, extending across a mounted window frame of a roof window, to thereby be able to lift the sash and the window pane of the window into position in the window frame if the window is being mounted, or lift the sash and the window pane out of the window frame if the window is being removed/refurbished.
  • Each support stand 2 comprises a support base 3, a support leg 4, and an angle bar 5.
  • the support base 3 is adapted to abut the roof to provide a stable grounding for the lifting tool 1 and distribute the weight of the lifting tool 1 and the window pane and sash of the window evenly across the roof construction.
  • the support leg 4 is adapted to carry the cross bar 6.
  • the support leg 4 is provided by a cylindrical metal tube with the required structural strength to carry the weight of the window pane and the sash of the window.
  • the angle bar 5 is adapted to extend between the support base 3 and the support leg 4 to stabilize the support leg 4.
  • the two support stands 2 hereby forms a triangle adapted to be set up along respective side elements of the window frame to carry the cross bar 6.
  • the support legs 4 must in an assembled condition be substantially vertical, whereby each support leg 4 will not experience torque during use, which would put an unnecessary strain on the support stands 2.
  • this means that the lifting tool 1 will be adapted for roof constructions of a certain inclination, as the triangle formed by the support base 3, the support leg 4, and the angle bar 5 has fixed side lengths and therefore also fixed angles, amongst which is the angle between the support base 3 and the support leg 4 which defines the support leg's 4 angle in relation to the roof and thereby also the ground.
  • the lifting tool can be adjusted for roof constructions with arbitrary inclinations.
  • the support leg 4 will thereby be able to be put in a vertical position regardless of the inclination of the roof.
  • Fig. 2 shows and embodiment of a support stand 2 of the lifting tool 1 of the invention in a folded condition.
  • the support base 3 of the support stand 2 is pivotably connected to the support leg 4 and the angle bar 5 about pivotable connection points adapted to not be easily releasable but instead to remain connected in all conditions of the lifting tool 1.
  • easily releasable it is meant that the connection points can be released by use of tools, but are not adapted to be separated unless smaller parts of the lifting stand 2 are being replaced.
  • connection point between the angle bar 5 and the support leg 4 is adapted to be releasable so that the angle bar 5 and the support leg 4 can be connected to bring the lifting tool 1 into an assembled condition, and so that the angle bar 5 and the support leg 4 can be separated to bring the lifting tool 1 into the folded condition.
  • connection point between the support base 3, the support leg 4, and the angle bar 5 can in principle be configured to be the releasable connection point.
  • the connection point between the support leg 4 and the angle bar 5 is however preferred as it is not subjected to the same load as the connection point between the support base and the support leg 4, and because it, in an assembled condition, is placed highest, thereby allowing the worker the connect or disconnect the connection point from a standing work position.
  • each support stand 2 is provided by a flat bar which is pivotably mounted on the side of the support base 3 at a top end of the support base 3, i.e. the end which, in an assembled condition is near the upper side of the roof window. Because the angle bar 5 is connected to the side of the support base 3, the angle bar 5 will fold down along the side of the support base 3 in the folded condition, whereby it will not occupy the same room as the support leg 4 which in the folded condition folds down along the top side of the support base 3.
  • the angle bar 5 is not carrying a significant weight, but merely supports the support leg 4, the angle bar 5 can be made from a lighter and weaker material and/or formed into a lighter and/or weaker shape than the support leg 4.
  • the angle bar 5 is therefore provided by a flat metal bar which do not have the same structural strength as the support leg 4.
  • connection hole 51 which allows the connection point between the angle bar and the support leg 4 to be displaced along the length of the angle bar 5, whereby the support stand 2 can be adjusted according to the roof inclination, so that the support leg 4 is substantially vertical in an assembled condition.
  • connection hole 51 is provided with a marking 52 indicating which roof inclination interval the respective connection hole 51 is adapted for.
  • connection holes 51 can be replaced by a single elongate slot, whereby continuous and not discrete adjustment of the connection point will be possible.
  • An embodiment with an elongate slot instead of a row of connection holes 51 will be able to be adjusted more precisely in relation to the roof inclination. However, this requires finer adjustment and therefore more time for the worker during assembly to avoid crookedness in the lifting tool 1.
  • each support stand 2 further comprises a batten hook 31 arranged at the top end of the support base 3.
  • the batten hook 31 is adapted to grip a batten in the roof construction over the top element of the window frame, so that the batten hook 31 prevents the lifting tool 1 from slipping down off the inclined roof construction.
  • the batten hook 31 can be withdrawn or inserted telescopically from/into the support base 3, whereby the batten hook 31 can be adjusted in relation to the distance between the window frame and the nearest batten.
  • Fig. 3 shows a lifting tool 1 of the invention in the folded condition. Because of the releasable connection point in each support stand 2, it is possible the fold each support stand 2 together to a very compact assembly. This construction further means, that the lifting tool 1, when it is disassembled only comprises three parts besides a winch 7, a drive extender 76, and a mounting strap 8.
  • Fig. 4 shows a lifting tool 1 of the invention in a packed condition, in which the two folded support stand2 lies side-by-side alongside the cross bar 6.
