The first cylindrical passage guides a fastening means (50) in the angle of inclination from a side edge of the object through the longitudinal object and into the base construction in order to attach the longitudinal object to the base construction.

Description

A MOUNTING TOOL

FIELD The present invention relates to a mounting tool. Mounting tools may be used e.g. by carpenters when mounting longitudinal objects with a predetermined spacing onto a base construction.

BACKGROUND The longitudinal objects have in prior art solutions been attached to the base construction with fastening means passing in a perpendicular direction through the front surface of the longitudinal object. The heads of the fastening means are then visible from the front surface of the longitudinal object. Another possibility in prior art solutions have been to attach the longitudinal objects so that the fastening becomes concealed from the front surface of the longitudinal object. This have been done by directing the fastening means in an inclined manner through the side edges of the longitudinal objects to the base construction. Still another possibility in prior art solutions has been to use special concealed fastening arrangements in connection with the side edges of the longitudinal objects. The costs for such special concealed fastening arrangements could be considerable. A mounting tool may help in positioning the longitudinal objects at a predetermined spacing from each other. A mounting tool may also comprise guide means for guiding the fastening means into a correct position in the longitudinal objects. The guide means may comprise guide elements guiding the fastening means in a perpendicular direction towards the front surface of the longitudinal object. The longitudinal object may in such an arrangement be S 25 attached with fastening means passing perpendicularly through the front N surface of the longitudinal object to the base construction. The fastening 3 arrangement of the longitudinal objects is thus not concealed i.e. the heads of x the fastening means will be visible on the front surface of the longitudinal I object. The guide elements may also guide the fastening means in an inclined * 30 manner e.g. when attaching two longitudinal objects placed in end-to-end & fashion on the base construction. The fastening means may pass in an inclined S manner through the end portion of the longitudinal objects positioned in an Q end-to-end fashion. The heads of the fastening means will still be visible in the end portions of the longitudinal objects in the front surface of the longitudinal object.

Most of the prior art mounting tools are intended for mounting of longitudinal objects formed of e.g. boards on a base construction formed of e.g. support beams in order to construct outdoor board decks. Such outdoor board decks may form terraces in connection with residential structures. The predetermined spacing between adjacent boards in board decks may usually be rather small e.g. in the order of 2 to 5 mm.

There is, however, also a need for other kind of building structures formed of space apart longitudinal objects in connection with residential structures. One example of such building structures are sun-shading structures used in connection with residential structures. Sun-shading structures may be constructed of spaced apart vertically or horizontally directed longitudinal objects attached to support beams. The sun-shading structure may be formed of a fence following a straight line or of a fence following a broken line. The broken line may have a zig-zag form seem from above. The spacing between adjacent longitudinal objects in such sun-shading structures may be bigger than in outdoor board decks e.g. in the order of 20 to 100 mm.

Another example of such building structures is ceilings in residential structures. A ceiling may also comprise spaced apart longitudinal objects.

There is thus a need for a simple and efficient mounting tool to be used when constructing a building structure in which spaced apart longitudinal objects are attached to a base construction.

SUMMARY An object of the present invention is to achieve an improved mounting tool.

The mounting tool according to the invention is defined in claim 1.

N The mounting tool comprises a a body having a general shape of a letter L with a first leg having a S top surface and an opposite bottom surface and a second leg having a front 8 surface and an opposite back surface, a length of the first leg determining a E 30 desired spacing between two adjacent longitudinal objects to be attached to a 0 base construction, the second leg comprising at least one first cylindrical i passage having an inlet opening at the front surface side of the second leg and S an outlet opening at the beck surface side of the second leg, the at least one N cylindrical passage passing with an angle of inclination through the second leg so that a centre of the inlet opening of the at least one cylindrical passage is at a greater distance from the bottom surface of the first leg compared to a centre of the outlet opening of the at least one first cylindrical passage, the at least one first cylindrical passage guiding fastening means in the angle of inclination from a side edge of the longitudinal object through the longitudinal object and into the base construction in order to attach the longitudinal object to the base construction.

The mounting tool may be used in building a structure in which spaced apart longitudinal objects are attached to a base construction. A transverse cross-section of the longitudinal objects may comprise two opposite — surfaces connected with side edges. Each one of the two opposite surfaces may be either planar or curved. Another possibility is that one surface is planar, and the other surface is curved. The two opposite surfaces may be parallel or non-parallel in case the two opposite surfaces are planar. The side edges may be straight or curved. The straight side edges may be parallel or non-parallel in case the side edges are straight. The side edges may be vertical or inclined. The corners between the opposite surfaces and the side edges may be sharp or rounded. A transverse cross-section of the longitudinal object may be rectangular or polygonal with straight or curved sides. The base construction may be formed of any structure into which the objects may be attached. The base construction may be formed of e.g. support beams. The longitudinal objects may be attached to the support beams so that a predetermined spacing remains between the longitudinal objects. The building of the structure with spaced apart longitudinal objects attached to a base construction may be done in the following way. The mounting tool may first be positioned on the base construction so that the first o leg of the mounting tool seats on the upper surface of the base construction AN and the outer end of the first leg of the mounting tool seats against the side N surface of the previously attached longitudinal object. The new longitudinal 2 object may then be positioned on the base construction so that the side edge © 30 of the new longitudinal objects is seating against the back surface of the E second leg of the mounting tool. A fastening means may then be positioned in © one of the first cylindrical passages in the second leg of the mounting tool. The > first cylindrical passage is chosen based on the thickness and/or width of the N longitudinal object to be attached to the base construction. The fastening N 35 means is also chosen based on the thickness and/or width of the longitudinal object to be attached to the base construction. The fastening means may then be directed from the side edge of the longitudinal object through the longitudinal object into the base construction so that the end of the fastening means sinks into the longitudinal object.

The mounting tool provides for an efficient, a safe and an optimal fastening of longitudinal objects at predetermined distances from each other on a base construction.

The mounting tool makes it possible to maintain a uniform and high quality throughout the installation of the longitudinal objects.

The mounting tool minimizes the risk of damages on the longitudinal objects as the position and the angle of the fastening means is fully controlled by the mounting tool. The fastening means will not split or otherwise damage the longitudinal object to be fastened.

The mounting tool may be manufactured in one working phase e.g. by casting or moulding. The mounting tool may be manufactured from a — uniform material or from a uniform combination of materials.

The mounting tool may be lifted without problems from the spacing between the longitudinal objects after the new longitudinal object has been fastened to the support beam. The mounting tool will not be pressed between the longitudinal objects after the new longitudinal object has been fastened to the support beam. The fastening means will be directed outwards from the second leg of the mounting tool. This means that the fastening means will not push the new longitudinal object to be fastened against the second leg of the mounting tool.

A diameter of the head of the fastening means to be used with the mounting tool may be substantially equal to or smaller than the diameter of the o thread of the fastening means at the head of the fastening means. The O fastening means may be formed of a longitudinal piece passing through the LÖ longitudinal object and into the base construction in order to attach the 2 longitudinal object to the base construction. The fastening means may be © 30 formed of e.g. a fastening screw or a fastening nail. In the case the fastening E means is formed of a fastening screw, then the thread of the fastening screw © may extend along the hole length of the shank of the fastening screw. The > fastening screw may have a long, tapered tip portion so that the fastening N screw may penetrate easily into the longitudinal object. The head of the N 35 fastening screw will penetrate a bit into the side edge surface of the longitudinal object so that the head of the screw is not visible from the front of the longitudinal object. The fastening of the longitudinal objects will thus form a concealed fastening. A drilling tool for fastening the fastening screws may be provided with a stop element so that the immersion length of the fastening screws remains constant throughout the installation of the longitudinal objects. 5 DRAWINGS In the following the invention will be described in greater detail by means of preferred embodiments with reference to the attached drawings, in which Figure 1 shows a front view of a sun-shading construction, Figure 2 shows a side view of the mounting tool, Figure 3 shows a front view of the mounting tool, Figure 4 shows a side view of the mounting tool in the mounting position, Figures 5-8 show side views of the mounting tool in connection with longitudinal objects of different form.

DETAILED DESCRIPTION Figure 1 shows a front view of a sun-shading construction. The figure shows an example of a sun-shading construction. The building of a sun-shading construction is one example of an application in — which the inventive mounting tool may be used. The sun-shading construction may be formed of longitudinal objects B1, B2, B3 attached to a base construction C1, C2. The longitudinal objects B1, B2, B3 may extend in a vertical direction. A transverse cross-section of the longitudinal objects B1, B2, B3 may comprise two opposite surfaces connected with side edges. The base N 25 construction C1, C2 may be formed of support beams C1, C2. The support N beams C1, C2 may extend in a horizontal direction. The longitudinal objects 3 B1, B2, B2 may be positioned at a first distance A1 from each other to the left 2 in the figure and at a second distance A11 to the right in the figure. The = distance A1, A11 between the longitudinal objects B1, B2, B3 may normally be N 30 the same throughout a sun-shading construction. The figure exemplifies that o there might be a need for different distances A1, A11 between the longitudinal S objects B1, B2, B3 in different structures. The figure shows a sun-shading structure with vertically directed longitudinal objects B1, B2, B3 attached to horizontally directed support beams C1, C2. A sun-shading structure may, however, comprise horizontally directed longitudinal objects B1, B2, B3 attached to vertically directed support beams C1, C2. The support beams C1, C2 may naturally also be inclined in the relation to the vertical and/or the horizontal direction. The sun-shading structure may be formed of a fence following a straight line or of a fence following a broken line. The broken line may have a zig-zag form seem from above. The spacing is normally much bigger in sun-shading structures than in outdoor board decks. Figure 2 shows a side view of the mounting tool and figure 3 shows a front view of the mounting tool.

The mounting tool comprises a body 10 having a general shape of a letter L. The body 10 may comprise a first leg 20 and a second leg 30. A length L1 of the first leg 20 may be dimensioned according to a desired spacing A1 between two adjacent longitudinal objects B1, B2, B3 to be attached to a base construction C1, C2.

The first leg 20 may have a fist length L1 and the second leg 30 may have a second length L2. The second length L2 may be bigger than the first length L1. The length L2 of the second leg 30 may be dimensioned to provide a firm handgrip of the second leg 30 above the longitudinal objects B1, B2. The body 10 may have a width W1. The width W1 of the body 10 may be the same in both legs 20, 30. Each leg 20, 30 could, however, have a different width. The first leg 20 may have a first thickness T1 and the second leg 30 may have a second thickness T2. The first thickness T1 and the second thickness T2 may be the same or they may be different.

The first leg 20 may comprise a top surface 21 and a bottom surface

22. The bottom surface 22 is opposite to the top surface 21. The bottom o surface 22 of the first leg 20 forms a bottom of the mounting tool. The second AN leg 30 may comprise a front surface 31 and a back surface 32. The back N surface 32 is opposite to the front surface 31. The second leg 32 comprises 2 further a top surface 33. The top surface 33 of the second leg 30 forms a top of © 30 the mounting tool. E The second leg 30 may comprise first cylindrical passages 41, 42, © 43, 44 comprising an inlet opening at the front surface 31 side of the second > leg 30 and an outlet opening at the back surface 32 side of the second leg 30. N The first cylindrical passages 41, 42, 43, 44 may pass with an angle of N 35 inclination through the second leg 30. A centre of the inlet opening of the at least one cylindrical passage 41, 42, 43, 44 may be a greater distance from the bottom surface 22 of the first leg 20 compared to a centre of an outlet opening of the at least one first cylindrical passage 41, 42, 43, 44. The first cylindrical passages 41, 42, 43, 44 may be inclined in relation to a first plane P1 being perpendicular to the second leg 30 of the mounting tool. A longitudinal centre axis of the first cylindrical passages 41, 42, 43, 44 may pass through the first plane P1 and form an acute angle with the first plane P1 above the first plane P1.

The longitudinal centre axis of each of the first cylindrical passages 41, 42, 43, 44 may be positioned at a different distance or height from the bottom surface 22 of the first leg 20 i.e. from the bottom surface of the mounting tool.

The first cylindrical passages 41, 42, 43, 44 may be positioned in two rows on the second leg 30. The two rows may be parallel. The use of two rows provides for more freedom in the position of the first cylindrical passages 41,42,43, 44.

Figure 3 shows the distances L41A, L42A, L43A, L44A of the centre of the inlet openings of the first cylindrical passages 41, 42, 43, 44 measured from the bottom surface 22 of the first leg 20. Figure 2 shows the distance L44A, L44B of the centre of the inlet opening and the outlet opening of the fourth cylindrical passage 44 measured from the bottom surface 22 of the first leg 20. The distance L44B of the outlet opening of the fourth cylindrical passage 44 measured from the bottom 22 of the first leg 20 is smaller compared to the distance L44A of the inlet opening of the fourth cylindrical passage 44 measured from the bottom surface 22 of the first leg 20. The difference in said distances L44A, L44B measured from the bottom 22 of the o first leg 20 is determined by the angle a44 of inclination of the fourth cylindrical AN passage 44. The angle 044 of inclination of the fourth cylindrical passage 44 N determines the inclination of the fourth cylindrical passage 44 in relation to the 2 first plane P1 being perpendicular to the second leg 30 of the mounting tool. © 30 Each of the first cylindrical passages 41, 42, 43, 44 may have an E angle of inclination of its own. The angle of inclination of each of the first © cylindrical passages 41, 42, 43, 44 and the height of the outlet opening of each > of the first cylindrical passage 41, 42, 43, 44 measured from the bottom 22 of N the first leg 20 may be adapted according to the thickness and/or width of the N 35 longitudinal object B1, B2, B3 to be mounted. The first cylindrical passages 41, 42, 43, 44 may on the other hand also have a common angle of inclination.

The figures show four first cylindrical passages 41, 42, 43, 44, but there could be any number of first cylindrical passages 41, 42, 43, 44 in the mounting tool.

The second leg 30 may comprise at least one first cylindrical passage, at least two first cylindrical passages, at least three first cylindrical passages etc.

The angle of inclination of the first cylindrical passages 41, 42, 43, 44 may have to be adapted in a different way in case the base constructions C1, C2 are made of harder materials, e.g. steel or aluminium profiles, compared to base constructions C1, C2 made of softer materials, e.g. wood or wood plastic composites.

The angle of inclination may have to be greater in connection with base constructions C1, C2 of harder materials compared to base constructions C1, C2 of softer materials.

The greater angle of inclination will reduce the risk of slipping of the fastening means 50 when penetrating the surface of the harder base construction C1, C2 material.

Each of the first cylindrical passages 41, 42, 43, 44 may be provided — with a marking on the front surface 31 of the second leg 30 of the mounting tool.

The marking may indicate the thickness and/or the width of the longitudinal object B1, B2, B3. The thickness and/or width of the longitudinal object B1, B2, B3 may be given as a single number or as an interval.

The person using the mounting tool will thus immediately know from the number or the interval, which of the first cylindrical passages 41, 42, 43, 44 should be used for the fastening of a longitudinal object B1, B2, B3 of a certain thickness and/or width.

All first cylindrical passages 41, 42, 43, 44 may have the same diameter.

Another possibility is that all first cylindrical passages 41, 42, 43, 44 have individual diameters i.e. all diameters are different.

Still another possibility o is that at least some of the first cylindrical passages 41, 42, 43, 44 have a N different diameter.

The diameter of the first cylindrical passages 41, 42, 43, 44 N depends on the diameter of the fastening means 50 to be used in connection 2 with the respective first cylindrical passage 41, 42, 43, 44. © 30 The diameter of each of the first cylindrical passages 41, 42, 43, 44 E may be uniform throughout the hole length of the first cylindrical passage 41, © 42, 43, 44. The first cylindrical passages 41, 42, 43, 44 could on the other > hand be provided with a sinking at the inlet opening of the first cylindrical N passage at the front surface 31 of the second leg 30. The sinking could be N 35 formed as a funnel guiding the fastening means 50 into the first cylindrical passage 41, 42, 43, 44.

The first cylindrical passages 41, 42, 43, 44 may guide fastening means 50 in the inclination angle through a side edge of the longitudinal object B1, B2, B3 to be attached to the base construction C1, C2. The first cylindrical passages 41, 42, 43, 44 may be positioned in a lower portion of the second leg

30. The lower portion of the second leg 30 being the portion of the second leg 30 that joins into the first leg 20.

The angle of inclination of the fastening means 50 is directed downwards towards the base construction C1, C2 in the second leg 30 of the mounting tool. The fastening means 50 pass from the inlet opening of the first cylindrical passages 41, 42, 43, 44 and further from the outlet opening of the first cylindrical passages 41, 42, 43, 44 into the longitudinal objects B1, B2, B3 and further into the base construction C1, C2. The fastening means 50 will thus not push the longitudinal object B1, B2, B3 to be fastened to the base construction C1, C2 against the second leg 30 of the mounting tool. The mounting tool will not be pressed between the longitudinal objects B1, B2, B3 after the new longitudinal object B1, B2, B3 has been fastened to the base construction C1, C2. The mounting tool may be lifted without problems from the spacing between the longitudinal objects B1, B2, B3 after the new longitudinal object B1, B2, B3 has been fastened to the base construction C1, C2.

An upper portion of the second leg 30 of the mounting tool may be provided with a second cylindrical passage 45. The second cylindrical passage 45 may extend perpendicularly through the second leg 30 of the mounting tool. The second cylindrical passage 45 may be used for suspending the mounting tool. A strip forming a closed loop may pass through the second cylindrical o passage 45 in the second leg 30. The strip may pass only through one AN mounting tool so that at mechanic may carry the mounting tool by suspending N the mounting tool from the strip on a hook. The strip could on the other hand 2 pass through several mounting tools, whereby several mounting tools may be © 30 suspended from a common hook. The second cylindrical passage 45 may be E formed of a hole passing through the second leg 30 of the mounting tool. © The first leg 20 of the mounting tool may comprises at least one > indication M1 passing in a transverse direction across at least a portion of the N first leg 20. The transverse direction is perpendicular to the longitudinal N 35 direction of the first leg 20. The indication M1 may be formed of simple line forming a marking for the cutting of the first leg 20. The line may extend along the whole width of the first leg 20 or only along a portion of the width of the first leg 20. The indication M1 may on the other hand be formed of a slot protruding into the first leg 20 from the upper surface 21 of the first leg 20. A cross section of the slot may have the form of a letter V. The slot may extend along the whole width of the first leg 20 or only along a portion of the width of the first leg

20. The first leg 20 may be cut along the indication M1 in order to adapt the length L1, L11 of the first leg 20 to the spacing A1, A11 between the longitudinal objects B1, B2, B3. The first leg 20 may thus be adapted to achieve different spacings A1, A11 between the longitudinal objects B1, B2, B3. There may be a further marking on the upper surface 21 of the first leg 20 in connection with each indication M1. The further marking may be a number indicating the length L1 of the first leg 20 at said indication M1.

Figure 4 shows a side view of the mounting tool in the mounting position.

The figure shows two longitudinal objects B1, B2 positioned at a distance A1 from each other. The longitudinal objects B1, B2 run in a direction perpendicular to the plane of the drawing. The base construction may be formed of support beams C1 running in the plane of the drawing. The first longitudinal object B1 has already been attached to the support beam C1. The mounting tool is positioned between the already installed longitudinal object B1 and the longitudinal object B2 to be installed. The bottom surface 22 of the first leg 20 i.e. the bottom surface of the mounting tool is seating against the upper surface of the support beam C1. The outer edge tip T20 of the first leg 20 of the mounting tool is seating against the first side edge B1a of the already Installed longitudinal object B1. The longitudinal object B2 to be installed is o positioned against the back surface 32 of the second leg 30 of the mounting AN tool. The fastening means 50 is thereafter positioned in a first cylindrical N passage 43 in the second leg 30 of the mounting tool. The first cylindrical 2 passage 43 to be used is the first cylindrical passage 43 that corresponds to © 30 the thickness and/or width of the longitudinal object B2 to be installed. The E fastening means 50 may then be made to penetrate the second side edge B2b © of the longitudinal object B2 to be installed and to pass further through the > longitudinal object B2 to be installed into the support beam C1. The tool for N managing the movement of the fastening means 50 may be provided with a N 35 stopper so that the tool stops the movement of the fastening means 50 when the head of the fastening means 50 has penetrated the second side edge B2b of the longitudinal object B2 to be installed. The head of the fastening means 50 is thus concealed within the second side edge B2b of the longitudinal object B2 to be installed to a person looking at the construction from the front of the longitudinal objects B1, B2.

The first opposite side edge B2a of the longitudinal object B2 to be installed may be attached by moving the mounting tool to the second side of the longitudinal object B1 to be attached. The thickness and the width of the longitudinal object B2 to be installed determines whether an attachment from only one side edge is enough or whether attachment from both side edges of the longitudinal object B2 is needed.

The longitudinal objects B1, B2 have a rectangular cross-section comprising a bottom surface, an opposite top surface and two opposite side surfaces. The bottom surface and the top surface may be parallel as shown in the figure, but this is not necessary. The two opposite side surfaces may also be parallel as shown in the figure, but this is also not necessary. The top surface and/or the bottom surface could e.g. be inclined or curved. The side surfaces could e.g. be inclined or curved.

Figures 5-8 show side views of the mounting tool in connection with longitudinal objects of different form.

Figure 5 shows a longitudinal object B1 having a cross-section forming a pentagon, figure 6 shows a longitudinal object B1 having a cross- section forming a letter H, figure shows a longitudinal object B1 having a cross- section forming of a droplet, and figure 8 shows a longitudinal object B1 having a cross-section forming of a letter X. The mounting tool may be used in connection with longitudinal objects B1 having a cross-section of practically o any form. O The body 10 of the mounting tool may have a general shape of a LÖ letter L. The first leg 20 and the second leg 30 may have a substantially 2 laminar structure. The legs 20, 30 could, however, be provided with protrusions © 30 etc. in order to facilitate gripping of the mounting tool. E The first leg 20 could be provided with an adjustable arrangement © for adjusting the length L1 of the first leg 20. The first leg 20 could comprise a > first part and a second part, the first part being stationary and the second part N being movably arranged in relation to the first part. The length L1 of the first leg N 35 20 could then be adjusted by moving the second part.

The mounting tool may be made from any solid material or a mixture of solid materials. The mounting tool could be made e.g. from wood or from plastic or from wood-plastic composite or from metal or from a mixture of metals or from any other composite. The wood may be heat threated wood. A heat threated wood-plastic composite may be used as the material for the mounting tool. It is an advantage if the mounting tool is not too heavy. A person using the mounting tool may thus easily carry the mounting tool e.g. on a tool belt. The strength and the durability of the mounting tool may also have an impact on the material to be used in the mounting tool. The mounting tool may be made as a single piece. Another possibility would be to make the first leg 20 and the second leg 30 as separate pieces being attached to each other. There could be a snap locking between the first leg 20 and the second leg 30. The first leg 20 could thus e.g. be pushed into the second leg 30. A set of first legs 20 of different lengths for different spacings between the longitudinal objects B1, B2, B3 to be installed could thus be provided. The mounting tool may be used in connection with the building of any building structure comprising longitudinal objects to be positioned at a predetermined spacing from each other. The building structure may e.g. be a sun-shading structure, a ceiling, a deck, etc. The mounting tool is especially suitable to be used in building structures in which the spacing between the spaced apart objects is not very small. A small spacing between the longitudinal objects may, however, also be achieved with the mounting tool. The dimensions of the mounting tool could be adapted according to the needs in each application where the mounting tool is used. The length L1 of the first leg 20 may be dimensioned according to the desired spacing o between adjacent longitudinal objects B1, B2, B3. The length L2 of the second AN leg 30 could be dimensioned so that the user may grip the mounting tool N above the longitudinal objects B1, B2, B3. The width W1 of the tool could be 2 dimensioned so that the mounting tool seats firmly on the base construction © 30 during the use of the mounting tool. The thickness T1, T2 of the mounting tool E could be dimensioned so that the guiding surface in the first cylindrical © passages 41, 42, 43, 44 for the fastening means 50 becomes long enough. > The thickness T1, T2 of the mounting tool could depend on the thickness N and/or length of the fastening means 50 to be used. The thickness T1, T2 of N 35 the mounting tool could be 2 to 5 times the diameter of the fastening means

50. The first leg 20 and the second leg 30 could have a different thickness.

The first cylindrical passages 41, 42, 43, 44 in the second leg 30 of the mounting tool could be made by drilling holes directly into the second leg 30 of the mounting tool. This would mean that the second leg 30 in the mounting tool should have a certain thickness T2 so that the first holes 41, 42, 43, 44 provide a long enough guide cylinder for the fastening means 50. The inlet opening of the first holes 41, 42, 43, 44 would be on the front surface 31 of the second leg 30 and the outlet opening of the first holes 41, 42, 43, 44 would be on the back surface 32 of the second leg 30.

The first cylindrical passages 41, 42, 43, 44 could on the other hand be made by drilling holes into the second leg 30 of the mounting tool and positioning cylindrical guide elements e.g. bushings into the holes. The cylindrical guide elements would then provide the first cylindrical passages 41, 42, 43, 44 guiding the fastening elements 50. The cylindrical guide elements could extend beyond the front surface 31 of the second leg 30. The back surface 32 of the second leg 30 should preferably form a plane surface onto which a side surface of the longitudinal object B1, B2, B3 to be installed can be positioned. The cylindrical guide elements could naturally also be attached to the front surface 31 of the second leg 30. The cylindrical guide elements would then not have to extend into the holes 41, 42, 43, 44 in the second leg 30 at all. The thickness T2 of the second leg 30 could thus be rather small.

The fastening means 50 may be formed of a longitudinal piece passing through the longitudinal object B1, B2, B3 and into the base construction C1, C2 in order to attach the longitudinal object B1, B2, B3 to the base construction C1, C2. The fastening means 50 may be formed of e.g.

fastening screws or fastening nails. The diameter of the fastening means may o e.g. be in the range of 4 to6mm. The length of the fastening means 50 may AN be adapted according to the thickness and/or width of the longitudinal object N B1, B2, B3 and/or the angle of inclination of the fastening means 50. The use 2 of fastening screws as fastening means 50 makes it able to use a drilling © 30 machine with a screwing tool to screw the fastening screws into the E longitudinal object B1, B2, B3 and the base construction C1, C2. Fastening © nails could in principle also be used, but a hammering tool fitting into the first > circular passages 41, 42, 43, 44 would then be needed. A hammer could be N used to hammer the hammering tool and thereby the fastening nail through the N 35 first circular passages 41, 42, 43, 44 into the longitudinal objects B1, B2, B3 and the base construction C1, C2.

The mounting tool may advantageously be used so that the longitudinal objects B1, B2, B3 are fastened directly with the fastening means 50 to the base construction C1, C2. It would, however, also be possible to use the mounting tool so that preliminary holes are first bored through the longitudinal objects B1, B2, B3 into the base construction C1, C2 by using the first circular passages 41, 42, 43, 44 as guide cylinders for the drill bit. The fastening means 50 would thereafter be directed through the first circular passages 41, 42, 43, 44 into the previously bored preliminary holes.

The longitudinal objects B1, B2, B3 may be of e.g. wood or wood- plastic composite. The wood may be e.g. heat threated wood or impregnated wood. The longitudinal objects B1, B2, B3 may be made by machining from a preform or by extrusion from a material in particle format.

The base construction C1, C2 may be of e.g. wood or wood-plastic composite. The wood may be e.g. heat threated wood or impregnated wood.

The base construction C1, C2 may be made by machining from a preform or by extrusion from a material in particle format. The base construction C1, C2 may on the other hand also be of metal. A suitable metal could be aluminium.

Examples of the dimensions of the longitudinal objects B1, B2, B3 are e.g. 25100 mm or 25*50 mm or 50*100 mm. The first number indicates the thickness and the second number indicates the width of the longitudinal object B1, B2, B3.

A transverse cross-section of the longitudinal objects B1, B2, B3 may comprise two opposite surfaces connected with side edges. Each one of the two opposite surfaces may be either planar or curved. Another possibility is that one surface is planar, and the other surface is curved. The two opposite o surfaces may be parallel or non-parallel in case the two opposite surfaces are AN planar. The side edges may be straight or curved. The straight side edges may N be parallel or non-parallel in case the side edges are straight. The side edges 2 may be vertical or inclined. The corners between the opposite surfaces and the © 30 side edges may be sharp or rounded. A transverse cross-section of the E longitudinal object B1, B2, B3 may be rectangular or polygonal or comprising © straight and curved portions with straight or curved sides. The longitudinal > objects B1, B2, B3 may be formed of e.g. boards, planks, laths etc. N The base construction C1, C2 may be formed of any building N 35 construction into which the longitudinal objects may be attached. The base construction C1, C2 may be formed of support beams. A transverse cross-

section of the support beams C1, C2 may comprise two opposite surfaces connected with side edges. Each one of the two opposite surfaces may be planar. The two opposite surfaces may be parallel. The side edges may be straight or curved. A transverse cross-section of the support beams C1, C2 may be rectangular with straight or curved side edges. The side edges may be vertical or inclined. The support beams C1, C2 may be formed of e.g. boards, planks, laths etc. The longitudinal objects B1, B2, B3 may be attached to the support beams C1, C2 so that a predetermined spacing remains between the longitudinal objects B1, B2, B3.

The mounting tool may be manufactured by casting or moulding e.g. injection moulding. Another possibility is to manufacture the mounting tool by machining.

The invention is not limited to the examples described above but may vary within the scope of the claims.
