Definitions

  • the invention relates to a wedge comprising an annular peripheral wall, wherein partition walls are provided between respective sides of the peripheral wall, said partition walls dividing the space within the annular peripheral wall into mutually separate compartments, wherein a number of the compartments are provided with a delimiting surface at a peripheral edge of the partition walls and optionally at portions of the adjacent peripheral wall, the surface of said delimiting face that faces away from the respective compartment serving as a support for an object positioned on said wedge.
  • Such wedges are well known and widely used within the construction industry, where there is a need for supporting and adjusting the length of building elements, such as floorings and windows in connection with building.
  • DK patent No. 141414 teaches a wedge of the type described above.
  • This prior art wedge is at both wedge surfaces provided with abutment surfaces for a support or a superposed wedge with a corresponding abutment surface.
  • the wedge is manufactured in an injection moulding process.
  • two wedges are employed that are shifted relative to each other, whereby planar support is achieved which is parallel relative to the support.
  • Such stacking of a plurality of wedges or positioning of a support element are considerably more troublesome that the establishment itself of the support by means of two wedges.
  • a support established in this manner is substantially less stable than a support formed of two wedge elements.
  • the delimiting surfaces of the wedge described above according to DK 141414 are found in all the compartments delimited by the peripheral wall and the partition walls at the peripheral peripheries of said walls, and thus they serve as abutment surfaces.
  • This prior art construction will thus be unsuitable for the manufacture of a wedge with a substantially increased height relative to its length and width, since there is a risk that the wedge may be distorted during the cooling that follows the injection moulding process, and may following cooling appear as a lopsided or distorted wedge. This is undesirable.
  • this is accomplished by providing a delimiting element at least in a number of the remaining delimiting compartments between the partition walls, and optionally portions of the adjacent peripheral wall, at a distance from the respective peripheral peripheries of said walls.
  • the risk of the finished wedge distorting during the cooling process is considerably reduced, and thus it is possible to form a high wedge at a substantially reduced production flaw rate compared to a wedge structure like the one described above in connection with the prior art.
  • the cores used in the injection moulding for the formation of the respective cavities are, depending on their longitudinal extent, able to distort sideways and thus, in case two cores are distorted in directions towards each other, the formation of an interjacent wall of a reduced wall thickness will result.
  • the strength of the wedge is hereby diminished, and therefore it is necessary to take this into account when dimensioning the wedge and during the subsequent determination of the wall thickness.
  • the present invention necessitates only that an elongate core be used in those compartments where a support surface is to be generated at a peripheral edge. In neighbouring compartments two short cores are used, one at each side of the desired delimitation, whereby the distortion of each of these is reduced.
  • the present invention provides a wedge that consumes less material relative its the desired minimum strength and which may be manufactured with a substantial height.
  • an elongate core is easier broken than a short core and the wedge construction according to the invention involves a reduced risk of operation shutdowns, since the number of cores of increased length has been reduced.
  • the wedge is so configured that the support surface of the wedge that faces towards another wedge during use is provided with a profile in the shape of teeth that extend transversally to the longitudinal direction of the wedge.
  • the wedge is so configured that the compartments in the wedge that are delimited by the peripheral wall and the delimiting walls have a minimum cross sectional dimension that constitutes at least 15 percent of the length of the same compartment.
  • each delimitation in the area that abuts on a partition wall or a peripheral wall has a reduced material thickness compared to the central portion of the delimitation.
  • each delimitation being chamfered in a direction towards the connecting area by a partition wall or a peripheral wall.
  • the wedge comprises an annular peripheral wall 1. Between opposed portions of the peripheral wall 1, transversal and longitudinal, 2 and 3 respectively, partition walls are provided in such a manner that in combination with the annular peripheral wall, they delimit areas 6,7,8 within the peripheral wall. At a peripheral, upwardly facing edge of partition walls and peripheral walls, a series of the delimited compartments are provided with a delimitation 4 that serve as support surface 4 during use for a further, complementary wedge which may be a usual, known wedge of a smaller height. These support surfaces 4 are provided with a chessboard-like pattern. Between these compartments having support surface delimitations, remaining compartments are provided, each having a delimitation situated at a distance from the respective peripheral edges of the partition walls and peripheral wall.
  • the wedge In the longitudinal direction of the wedge thus exemplified, the wedge has to rows of cavities and support surfaces, respectively, since a longitudinal partition wall 3 is exclusively provided between opposite sides of the peripheral wall.
  • the compartments or cavities in question have a relatively large transversal dimension T compared to their lengths in order to hereby be able to allow use of correspondingly thick cores in the injection moulding tool and hereby minimise the risk of the cores breaking with ensuing operation shut-downs.
  • a serrated profile is provided with teeth in three rows 9,10,11, wherein the middle row of teeth 10 is displaced by the width of half a tooth relative to the remaining two rows of teeth 9,11 in order to hereby prevent that a superposed wedge with a corresponding profile may be shifted sideways.
  • the compartments which do not at their ends comprise delimitations serving as abutment surfaces, have delimitations arranged at a distance from the peripheral edges of these peripheral wall and partition wall portions.
  • delimitations or transversal walls are positioned like this in order to counteract lopsidedness or distortion of the finished product during the cooling process which is otherwise very likely to occur.
  • the delimitations 5 are provided at the same distance from that of the two peripheral edges of the peripheral wall and partition walls which is opposite the peripheral edge, where the remaining compartments are provided with delimitations 4 serving as abutment surfaces.
  • the tool portion used in this area in the production of other wedges, optionally with an increased or reduced height, wherein it is also required that the delimitation is situated at a distance from the peripheral edge.
  • FIGs 4-6 illustrate a modified embodiment of the wedge shown in Figure 1-3 wherein the wedge is so configured that each delimitation 5 in the area 12 that is adjacent to a partition wall or peripheral wall is has a reduced material thickness compared to the central portion of the delimitation, each delimitation being chamfered 12 in a direction towards the connecting area with a partition wall or a peripheral wall.
  • delimitations with a relatively increased material thickness in order to hereby ensure a considerably improved nailability, i.e. the option of nailing the wedge to a support without an ensuing risk of the wedge being damaged, and without suctions occurring in surfaces of the wedge due to the relatively increased material thickness.
