    l DK 2020 00478 A1 A wedge system for use in laying out flooring Field of the invention The present invention generally relates to the technology of laying out floors.
    — More specifically, the present invention in a first aspect relates to a wedge system for adjusting and fixing the distance between a lower support and an upper joist and comprising two wedges.
    In a second aspect the present invention relates to the first wedge of the wedge system of the first aspect of the present invention.
    In a third aspect the present invention relates to the second wedge of the wedge system of the first aspect of the present invention. In a fourth aspect the present invention relates to a process for the manufacture of a wedge as defined according to the first, the second or the third aspect of the present invention. In a fifth aspect the present invention relates to the use of a wedge system according to the first aspect of the present invention, or of a wedge according to the second or third aspect of the present invention for adjusting and fixing the distance between a lower support and an upper joist in the process of construction a floor. In a sixth aspect the present invention relates to a method of constructing a floor.
    Background of the invention Within the field of laying out wooden floors in a building one usually uses an array of existing support beams extending at regularly distances throughout the area of the room in which it is desired to layout a wooden floor. Alternatively, a concrete floor is used as lower support for the flooring. On top of the support, joists are arranged at regular mutual distances.
    — In case support beams are used as supports, the joists are typically laid out in a direction perpendicular to the underlying support beams.
    , DK 2020 00478 A1 Now, when laying out a floor it is of paramount importance that the resulting floor will be horizontal and that no bulges will be present. In order to secure this, it has been customary for many years to a wedge system comprising two identical, but oppositely arranged wedges, in a fashion where the apex of one wedge will — be directed in an opposite direction as the apex of the other wedge, between the joist and the underlying support. By displacing one wedge of such a wedge system relative to the other wedge in a direction defined by the two opposing apices, it will be possible to adjust the effective height distance between the joist and the underlying support. Accordingly, once all the joist have been laid out on top of the underlying support and once a plurality of prior art wedge systems have been arranged between a joist and the underlying support, the flooring worker may carefully ensure, by adjusting the position of two wedges of each wedge system, relative to each other that the upper surfaces of each joist are level. Subsequently, the vertical distance defined by each wedge system is fixed by ramming a nail through the joist and through each of the two wedges of the wedge system.
    — Although this solution to the problem of securing a floor surface which will be in level throughout indeed provides for fixation of the joist in the right vertical height and although this solution has been applied for decades, the prior art wedge system nevertheless represents a number of disadvantages.
    One disadvantage is the wedges of the prior art wedge system does not allow locking, at a given height of the system, of one wedge relative to the other wedge.
    Another disadvantage is that in order to fix the two wedges making up a wedge system, once a mutual vertical height therebetween has been found, a nail need be rammed through the system. Such nailing represents a working step taking up a certain amount of time. Moreover, in case it is found that an error has been made during the layout or fixation of the wedge system so that part of or the whole layout of the wedge systems and/or the associated joists have to be redone, the worker will have to spend a considerably amount of time in removing the nails used for fixing the wedge systems.
    Additionally, during such removal of the nails it is almost inevitably that at least part of the wedges of the wedge systems will be damaged beyond repair, so that some of these wedges
    DK 2020 00478 A1 3 have to be replaced. Such replacement imposes additional material cost to the construction work.

It is seen that the two tracks 10 of the first engagement surface 8 is being inclined at an angle al, relative to a plane P1 defined by the first support surface 6 of the first wedge 200. The first engagement surface 8 furthermore comprises a first locking element 14 in the form of a recess 28 extending from an opening 30 and into the body 2 of the first wedge 200 in a transversal direction Y. The recess 28 is having an extension in the longitudinal direction X essentially corresponding to the longitudinal extension of the first engagement surface 8. It is also seen that the recess 28, at least partially, is being arranged at a raised position relative to the two tracks 10 of the first engagement surface 8. — Fig. 3b shows a second wedge 300 of the wedge system 100 comprising a second body 4. The second wedge 300 comprises a second support surface 16 and an opposite, first engagement surface 18.
    1 DK 2020 00478 A1 The second engagement surface 18 is having an extension in a longitudinal direction X and in a transversal direction Y. The second engagement surface 28 comprises two tracks 20 comprising second engagement means 22 and the tracks extend in a longitudinal direction X.
    It is seen that the second engagement means 22 extends in the longitudinal direction X along a plane, and that the second engagement means 22 of the second wedge 300 defines a three- dimensional waveform comprising a number of repeating wave crests and wave troughs, and that the wave crests and the wave troughs are having an extension in a transversal direction Y.
    It is seen that the two tracks 20 of the second engagement surface 18 are being inclined at an angle a2, relative to a plane P2 defined by the second support surface 16 of the second wedge
    300.
    The second engagement surface 18 furthermore comprises a second locking element 24 in the form of a protrusion 32 having a free end 34 extending in a transversal direction Y.
    The protrusion 32 is having an extension in the longitudinal direction X corresponding to only a fraction of the longitudinal extension X of said second engagement surface 18.
    — Itis also seen in Fig. 3b that the protrusion 32, at least partially, is being arranged at a lowered position relative to the two tracks 20 of the second engagement surface 18.
    The recess 28 of the body 2 of the first locking element 14 of the first wedge 200 is being configured for accommodating the free end 34 of the protrusion 32 of the second locking element 24 of the second wedge 300.
    Now looking at Fig 3a and fig 3b collectively, the system 100 comprising the first wedge 200 and the second wedge 300 is configured in such a way that the geometry and dimensions of the first engagement means 12 of the first wedge 200 on the one hand, and the geometry and dimensions of the second engagement means 22 of the second wedge 300 on the other hand are able to enter into engagement with each other.
    Moreover, the geometry and dimensions of the first locking element 14 of the first wedge 200 on the one hand, and the geometry and dimensions of the second locking element 24 of the second wedge 300 on the one hand are adapted to each other in such a way, that when the first engagement means 12 of the first wedge 200 has entered into engagement with the second engagement means 22 of the second wedge 300, the first wedge 200 and the second wedge
    8 DK 2020 00478 A1 300 will be able to shift between a locking configuration and an unlocking configuration by displacing the first wedge 200 relative to the second wedge 300 in a transversal direction Y. Once being in a locking configuration with each other, the locking means 14,24 of the first wedge and said second wedge, respectively, prevents disassembly of the two wedges merely by a displacement of the first wedge 200 relative to the second wedge 300 in a direction Z perpendicular to both the longitudinal direction X and the transversal direction Y. Hereby the two wedges 200 and 300 of the wedge system 100 can be secured and/or locked to each other. The individual steps in the process of assembling the first wedge 200 and the second wedge 300 of the wedge system 100 according to the first aspect of the present invention is illustrated in Fig. 4a — 4f and in Fig. 5a — 5f, respectively.
    Fig. 4a, 4c and 4e are front views illustrating the process of assembling the first and second wedge of the inventive wedge system at a relatively low height. Fig. 4b, 4d and 4f are side views illustrating the process of fig. 4a, 4c and 4e.
    Fig. 4a illustrates the wedge system 100 comprising a first wedge 200 and a second wedge
    300. The two wedges are arranged relative to each other in such a way that their respective engagement surfaces 8,18 are facing each other and in such a way that the opposing two support surfaces 6,16 are essentially parallel.
    It is seen in fig. 4b as illustrated by the arrow that the two wedges are about to be brought into — contact with each other and in such a way that a relative small distance will be created between the first support surface 6 of the first wedge 200 and the second support surface 16 of the second wedge 300.
    Fig. 4c and 4d are side views illustrating that the two wedges 200 and 300 have been brought into contact from the situation depicted in Fig. 4c and 4d. In the configuration illustrated in Fig. 4c and 4d the first engagement means 12 of the first engagement surface 8 of the first wedge 200 have been brought into engagement with the second engagement means 22 of the second engagement surface 18 of the second wedge 300. However, the first locking element 14 of the first wedge 200 and the second locking element 24 of the second wedge 300 have not yet been brought into a locking configuration. This is evidenced by the fact that first
    19 DK 2020 00478 A1 wedge 200 and the second wedge 300 are arranged slightly offset in a sideway direction (Y direction) in relation to each other, as seen in fig. 4c. In Fig. 4e and 4f the last process step has been performed, viz. the first locking element 14 of the first wedge 200 and the second locking element 24 of the second wedge 300 have been brought into a locking configuration with each other. This step was performed by bringing the two wedges 200,300 into an aligned orientation with each other by effecting a transversal movement (in the Y direction) of the first wedge 200 relative to the second wedge 300. It is seen in Fig. 4f that the distance between the first support surface 6 of the first wedge 200 and the second support surface 16 of the second wedge 300 defines a relatively small height HI. Fig. 5a — Sf illustrates a similar procedure as the one illustrated in Fig. 4a — 4f. However, this time resulting in a relatively large distance H2 between the first support surface 6 of the first wedge 200 and the second support surface 16 of the second wedge 300, as illustrated in Fig. sf.
    Fig. 6 is a partial cross-sectional view illustrating one embodiment of a first engagement means of a first wedge, or a second engagement means of a second wedge. Fig. 6 show the body 2,4 having an engagement surface 8,18 which comprises engagement means 12,22. The engagement means comprises a number of recurring wave segments S1,82,S; comprising wave crests C and wave troughs T. Each wave segment S1,S,,S3 extend from one wave crest C to the adjacent wave crest C. The wave length A is hence defined as the distance, in a longitudinal direction X, from one wave crest C to the adjacent wave crest C. The wave height WH is defined as the distance, in a direction Z being perpendicular to the longitudinal direction X and the transversal direction Y, between a wave crest C and the adjacent wave trough T.
