Description:
Titel:

A MOUNTING TOOL FOR MOUNTING/DEMOUNTING OF WINDOWS, DOORS AND SIMILAR IN A WALL OPENING.

TECHNICAL FIELD

The present invention relates to a mounting tool for mounting, for example installing or removing, a mounting object mounted in a frame, such as a window, a door or similar, in an opening in a wall with an outer and an inner side. Said mounting tool comprises a first mounting element and a second mounting element provided with a counterstay element adapted to function as a wall counterstay bearing against the inner side of a wall and a frame holding device respectively, wherein the distance between the counterstay element and the frame holding device can be preset.

STATE OF THE ART

Mounting of windows or doors in a wall opening is associated with difficulties for many different reasons. Windows and doors respectively are normally heavy and at mounting/demounting, there is nothing to keep the window or the door in place but there is a risk that it falls out of the opening, either outwards or inwards. Furthermore the requirements on adjustment in horizontal as well as in vertical direction are high in order to ensure that an installation can be carried out in a correct way. It is apparent which are the risks if a window or a door would fall out of the wall opening, outwards, during mounting, but also if it falls out of the opening towards the inner side, there may be considerable damages, both for the person mounting the window or the door, e.g. the window may break. Therefore external safety arrangements or similar provided on the outside are often used in order to prevent falls towards the outside since mounting mostly take place from the inside of a room or a house, but it is apparent that it is very complicated to arrange such safety arrangements, particularly when mounting has to take place on high heights or in multitenant buildings etc.

Furthermore the dimensions of the mounting objects as well as of the frames in which there are mounted differ to a high extent, as well as thickness and material of the wall in which the opening is provided.

Several different devices are known. It is known to use mounting devices which by means of guiding rails translate and hold for example a window in order to prevent it from falling out. Such guiding rails engage the outer and inner sides of the frame and they are anchored on the wall inner side. After mounting, the mounting device has to be removed, which is complicated and may involve damages on the wall and/or on the frame. Often different kinds of wedges and blocks are used in order to adjust the mounting object, which is both time consuming and complicated.

It is also known to prevent a mounting object from falling out by fixing counterstays, for example boards or similar, on the outside. After mounting thereof, it is also difficult to remove them. In addition thereto it also requires arranging wedges or similar vertically as well as horizontially before the actual mounting of the mounting object can take place.

SE 530 818 describes a mounting device for windows comprising an elongate guiding rail. Two such guiding rails are mounted so that they point in a direction towards and across the surface of the window. The guiding rails are provided with front parts which are anchored in the frame, close to the window, in order to hold it tightly and they are provided with a displaceable securing portion which is attached to the wall. A number of frame sleeves are screwed onto the frame of the window in existing pre-bored holes, and in an interspace between the wall and the frame they form protruding portions forming anchoring points for fastening of said front parts. These protruding portions are screwed on in order to support against the edge surfaces of the wall after the frame has been guided into the opening. I.e. mounting armatures with frame sleeves are connected to the outside of the window frame, the window is mounted in an opening and it is secured against the wall by means of the angle of the mounting armatures. In order to fit to different wall thicknesses, the mounting armatures are provided in packages with three different lengths for different window dimensions, and such a package can only be used for a limited number of windows or doors, for example fifteen.

It is thus a disadvantage of this tool that it cannot be used for a larger number of windows or doors, and that different tool sets are needed. Furthermore the known tool is inflexible in that it has to provided in different forms depending on for example the dimension of the window. The known tool can also not be used if the houses are made of brick due to the requirements on strength when screwed into the wall. A further considerable disadvantage is that damages are produced on mounting object and wall .

Another known device as described in DE 202007014070 Ul shows a device comprising a rod with two counterstays and a tensioning device. The rod has to be introduced between frame and wall and one counterstay is intended to grip around the outer side of the window frame when are counterstay is intended to bear against the inside of the wall to prevent the window from falling out towards the outside. The distance between the counterstays can be adjusted and the counterstays thus protrude in different directions from the rod. A drawback of the tool is that it has to be inserted into the gap between the frame and the wall or casement, which has as a consequence that there are requirements on the thickness of the tool, the rod and the outer counterstay which in turn may have as a result that the stability and strength threreof will not be sufficient and it can also result in difficulties to, after completed mounting, remove the tool.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a mounting tool and a method respectively for mounting a mounting object, such as a window or a door, in an opening in a wall, wherein the mounting/demounting, i.e. installation/removal, of a window or a door can take place in a secure manner and without running the risk that the mounting object falls out of the opening, inwards or outwards. It is also an object of the invention that mounting/demounting shall take place without the arrangement of the mounting tool somehow damaging the wall or the mounting object or its frame. It is also an object of the invention to provide a mounting tool which is easy to handle, which can be adjusted in order to be adapted for mounting/demounting of different kinds of windows or doors in walls which also can be of different kinds, of different thicknesses, be of different materials, wood, brick or similar, and that the tool is easy to remove after the mounting object in a secure manner has been mounted in the opening so that for example final installation (removal) can take place. It is also an object of the invention to provide a mounting tool through which substantially no damage whatsoever is produced, neither on wall nor on mounting object, and in that, to a large extent, the use of wedges or similar can be avoided, and if such still are used, then only optionally in some embodiments and to a very limited extent. Particularly it is an object to provide a universal tool for mounting of windows or doors which is very easy to use and which in practice does not require the use of any other tools for application or removal of the mounting tool itself. It is thus also an object of the invention to provide a method through which one or more of the above mentioned objects can be achieved.

A further object of the invention is to provide a method and an arrangement wherein the mounting can take place without holding, i.e. that it is enough to use applied mounting tools in order to be able to safely fasten, loosen or readjust a window, a door etc. Therefore a mounting tool as initially referred to is provided which has the characterizing features of claim 1.

A method is therefore also provided which has the characterizing features of claim 14.

Advantageous embodiments are given by the characterizing features of the dependent claims.

It is an advantage of the invention that a mounting tool is provided which is easy to use and which can be used without requiring screws, nails or similar, neither in the mounting objects, nor in the walls, and that no damages are caused, neither on the mounting object, nor on the wall, and that mounting or demounting of the mounting object can take place in a very safe manner involving no risks, and that mounting/demounting using the proposed tool also is very fast and can be carried out with fewer installers than known mounting procedures .

according to Fig. 4 more in detail, and Fig. 6 schematically illustrates a mounting tool, for example according to Fig. 1, arranged in a frame with the tap introduced into a pre-bored frame hole. DETAILED DESCRIPTION OF THE INVENTION

The mounting tool 100 in Fig. 1 comprises a first hollow mounting element 20 and a second mounting element 10, which, since it has a smaller cross section than the first mounting element 20, is displaceably arranged therein, so that the total length of the mounting tool can be adjusted. Essential is not that the length of the mounting tool can be preset, but that the distance can be set between a first counterstay 21 of the first mounting element 20, which is arranged to, during a mounting/demounting operation, bear against an inner wall, and a frame holding device 11, 12 provided on the second mounting element 20. In this embodiment the counterstay 21 is formed with a step in order to be adaptable to function as a support against the frame and the wall, for example if the frame is protruding or if the wall is particularly thin or similar. The wall counterstay 21 could also be arranged as a straight band shaped element or similar. In this embodiment the first counterstay element 21 is fixedly connected at the outer end of the first mounting element 20 which is closest to the outer end of the second mounting element 10 which is provided with a frame holding device 11, 12.

In this particular embodiment the mounting device 100 is also provided with a second counterstay element 22 which is located at a certain distance from counterstay element 21 and pointing in a direction which is opposite to the direction thereof, i.e. the two counterstay elements are parallel but mounted to form an angle of 180° in relation to each other on the first mounting element 20. The first wall counterstay 21 is intended for smaller wall thicknesses, for example for thicknesses up to 1-12 cm, whereas the second wall counterstay is intended for larger wall thicknesses, for example from 11-12 up to about 20-25 cm. These figures are of course only given for exemplifying purposes and the wall thicknesses can be larger as well as smaller for the given counterstay elements. In a further embodiment the first mounting element may be provided with one or two additional wall counterstays arranged to form angles of approximately 90° in relation to said first and said second wall counterstay respectively. The frame holding device here comprises a pin 11 which can be in the form a round bar protruding in parallel with said first and said second wall counterstay respectively and it is fixedly mounted at the outer end of the second mounting element 10 or at a certain distance from the outer end. In this embodiment the second mounting element 10 is also provided with a frame counterstay 12 arranged in parallel with said pin 11 and intended to, as a part of the frame holding device, cooperate with pin 11. Pin 11 is intended to be introduced into a pre-bored frame hole on the inside of a frame of for example a fixed frame window and frame counterstay 12 is thus arranged to bear against the inner side of the frame, i.e. the room side from which mounting takes place. An edge or similar can be used between frame counterstay and frame but it is not necessary and it depends on how the frame counterstay is formed. Depending on whether the wall is thick or thin, the mounting elements 10 and 20 can be separated by means of adjustment means 30 insofar that they can be rotated so that instead of for example wall counterstay 21, wall counterstay 22 can be used, which then is parallel with pin 11 and frame counterstay 12. The adjustment means comprises a threaded screw or similar which for example by means of a nut and a washer are connected to/at the outer, distant edge of the second mounting element 10 and for example by means of a nut 31 and a washer at the opposite end of the first mounting element 20. By means of actuating, or gripping, means 35 arranged at the outer end, by turning the adjustment means protruding out of the mounting element 20, the distance between the frame holding device 11 and the wall counterstay 21 (or if relevant wall counterstay 22) can be adjusted. In one embodiment the adjustment screw 30 is rotatably connected and engages in, or close to, the outer end of the mounting element 10, for example provided with a nut element 31 or similar at the other hand of first mounting element 20, and by screwing the length can be adjusted, elements 10 and 20 can be disengaged to allow a coarse adjustment so that the appropriate wall counterstay can be used, in case there are several optional wall counterstays .

The tool can thus be preset in a coarse manner in order to enable use of either wall counterstay 21 or wall counterstay 22 depending on the thickness of the wall where the window or the door is to be mounted and the used counterstay is intended to bear against the inner side of the wall surrounding the window or door opening. Adjustment in an extended position takes place by means of rotation, in this case 180°, of the first mounting element 20 in relation to the second mounting element 10, at maximal extension if the cross-section of the telescopic elements for example are quadratic or rectangular, so that they are disengaged and only are limited in their motion by means of screw 30. Also other shapes of mounting elements 10 and 20 respectively are possible, such as triangular, circular with guiding grooves at the inner surface of the mounting element intended to be the outermost and at the outer surface of the mounting element intended to be the innermost element etc. Pin 11, which is arranged perpendicularly to the longitudinal extension of element 10 and 20 respecitvely at the end of element 20 which is located at the largest distance from element 10 in an extended position, is intended to be introduced into a pre-bored hole in for example a window with a fixed frame (a visible hole at the inside of the frame) during a mounting/demounting operation or during adjustment. After a mounting/demounting operation or an adjustment operation has been completed, tool 100 is simply released when, by means of screw 30, the distance between wall counterstay and frame holding device has been somewhat increased, since pin 11 is releasably introduced from the inside. The window embrasure depth can be adjusted by means of screw 30 and counterstay element 21 (or 22) prevents the window from falling out.

Fig. 2 shows an alternative embodiment of a mounting tool 200 which comprises a first mounting element 20A, a second mounting element 10A, a first wall counterstay 21A, a second wall counterstay 22A and an adjustment screw 30A with actuating, or gripping, means 35 similar to the embodiment of Fig. 1. In this case the frame holding device 11A comprises a pin or a round bar with a circular cross section which either protrudes perpendicularly at one side of the second mounting element 10A or at both sides (shown) . However, in this embodiment there is no frame counterstay, but wall counterstay 21A or 22A cooperates directly with the frame and the wall. As in Fig. 1 wall counterstay 21A and/or 22A can be provided with a step, such as for example in the form of a partial S, or with an appropriately angled and formed step, in order to grip the inner side of the frame with its inner end and bear against the inner side of the wall by means of its outer end. The inner side of the frame here means the side which, when a mounting object is mounted, is parallel with the inside surface of the wall, and the inside of the frame here refers to the sides of the frame which are directed towards one another, perpendicular to the inner side of the frame and closest for example to the window pane. Different embodiments are possible and the length may be between 8-10 and 20 cm or more. Also in this case several alternative wall counterstays may be provided, the pin can protrude in one direction or in two directions, with the advantage that if the pin protrudes in two directions, the tool may simply be rotated 180° and no coarse adjustment needs to be done if instead of the wall counterstay 21A, 22A, or vice versa, needs to be used depending on the wall thickness.

A wall counterstay may, for example as shown in Fig. 2, of course be provided with holes for screwing on by means of screws as an additional means for keeping the device in place, but this is in no way necessary for the functioning of the invention and is normally not used; a purpose with the invention is particularly to eliminate the need to use screws in the wall, in the frame etc.

Fig. 3 shows an alternative, simplified mounting tool 300 with a first mounting element 20B, a second mounting element 10B, and an adjustment device 30B with actuating, or gripping means 35B as in Figs 1 and 2. In this case there is only one wall counterstay 21B and also the pin or the round bar with a circular cross section 11B protrudes only in one direction which means that there is no possibility for a coarse adjustment. Frame counterstay 12B thus forms part of the device as in Fig. 1, but it could also be excluded as for example shown in Fig. 2. Wall counterstay 21B is here provided with a step but it could also be straight or have some other shape. In another preferred embodiment (not shown) the pin (and an optional frame counterstay) only protrudes in one direction, but there are two wall counterstays enabling a coarse adjustment.

Fig. 4 shows an alternative embodiment of a mounting tool 400 with a first mounting element 20C, a second mounting element IOC with an adjustment device 31C and actuating or gripping means 35C as in Figs. 1-3. Also in this embodiment are shown a first wall counterstay 21C and a second wall counterstay 22C which is arranged at an angle of 180° in relation to said first wall counterstay 21C. Even if the first wall counterstay is shown as being of a shape with a step intended to take the frame width and/or frame thickness into account, the first wall counterstay could have the same shape as the second wall counterstay, i.e. straight. Conversely, the second wall counterstay could be step- formed as the first wall counterstay or it could have some other appropriate form. The shown embodiment is also not limited to two wall counterstays but there could also be one or three. What differs in this embodiment is that the frame holding device 11C in this case is made of two parts, in certain embodiments adapted to the frame, and arranged to cooperate with the inside, the inner side of the frame and the outer side and a part of the outside.

Fig. 5 shows in a more detailed manner the frame holding device llC as described above according to this preferred embodiment. The frame holding device 11C comprises a first part 111 which comprises a flat, thin element intended to bear against the outer side of the frame and which is fixedly mounted at the outer end of the second mounting element 10 as a flat, extended prolongation thereof, for example at one side. The other part of the frame holding device 112 comprises an angled element intended to be detachably, possibly also adjustably, arranged in relation to the second mounting element 10 or the first part 111 respectively. The angled element 112 comprises a first flat part 112i, which in a mounted state is perpendicular to said first part 111 and intended to bear against the inner side of the frame, a second flat part 112 2 intended to bear against the inside of the frame, and a third flat part 112 3 substantially parallel with said first flat part 112i, but possibly considerably shorter, and intended to bear against a part of the outer side of the frame. Preferably said first flat part 112χ is provided with an securing element 113. This securing element 113 can be threaded at the inside and be adapted to be arranged on a mounting screw 114 or similar provided on the second mounting element 110, at its outer end, and be fastened by means of a nut, for example a wing nut 115 or similar. Particularly the second frame holding part 112 is adapted to the shape and the dimensions of the respective frame and the only requirement is that it should be possible to mount, for example on mounting screw 114, by means of its securing element 13.

Fig. 6 shows an embodiment of a mounting tool, for example according to Fig. 1, which is arranged to hold a mounting object in a frame 40 at a wall during a mounting, demounting or adjustment operation. A wedge 41 can be introduced between frame 40 and frame counterstay 12 in some embodiments but this is not necessary, though. With an introduced wedge 41 the mounting tool 100 will preferably be held substantially perpendicular to the frame 40. The need for introduction of a wedge among other things depends on the distance between the frame counterstay 12 and pin 11. The wedge can have different sizes and be made of different materials.

According to one embodiment a mounting operation can be carried out as follows:

In this particular case the window is a so called fixed frame window with pre-bored frame holes. Alternatively the invention may of course also include the boring of holes in the frame in order to be able to use the mounting tool. Two tools (for example 200, 200) are introduced into opposite (for example pre- bored) frame holes, for example two upper frame holes of a window frame. In order to fit to the wall thickness, a coarse pre-adjustment operation is implemented as discussed above, i.e. it is determined which of the wall counterstays that should be used, if the tool is provided with alternative, optinal wall counterstays. This can also be done before arranging the mounting tools in the frame holes. The arranging in the holes consists in that the pin or the round iron bar of circular cross section is introduced into the hole. The window is thereupon lifted up and located, and through screwing on/screwing off the adjustment screw using the actuating means, the tool can be adjusted depending on the embrasure depth. Since the wall counterstays bear against the inner side of the wall surrounding the window, the window is prevented from falling out towards the outside. At this stage (or earlier) it is possible to open the window slightly in order to further reduce the risk of the window falling out of the opening towards the inside, but this is not always necessary. Thereafter the window is fastened by means of screws in a conventional manner through the lower frame holes. When the window is sufficiently fixed, the tools are removed and the window can be fastened by means of screws also through the upper, for example pre-bored, frame holes. The mounting tool can of course also be used for adjusting purposes in which case screws on opposite sides can be unscrewed, the mounting tool can be introduced and adjustment can take place through the other frame holes, upper or lower. In those cases when frame counterstays are used, small-size wedges can in an easy manner be introduced between the frame and the frame counterstay, in other respects the method corresponds to the method described above. Since, for securely keeping the mounting object in place, no boring is required, neither in the frame nor in the wall, mounting/demounting can take place independently of the wall material, concrete walls as well as wooden walls. For windows without pre-bored holes, a mounting tool as described in Fig. 4 may with advantage be used. Then the frame holding devices may be adjustable to either fit different frame dimensions and/or be adjustable by means of an adjustment device in order to be adapted to different frame dimensions. Then the first frame holding part is brought into the intended position, the window is slightly opened, the second frame holding part is attached by screwing on. After that the procedure is the same as that described above. Alternatively holes may be bored in the frame in order to enable use of a mounting tool with a pin.

Materials used for making the tool can be selected in an appropriate manner. In advantageous embodiments conventional structural steel or iron is used. It may for example be coated with zink or hot galvanized. In an advantageous embodiment it is powder varnished. Of course also other materials normally used for tools, for example clamps or similar, may be used.

The invention is of course not limited to the illustrated embodiments, but it can be varied in a number of ways within the scope of the appended claims.
