Description

den kendte kile ingen foranstaltninger til sikring mod, at to oven på hinanden anbragte kiler kan skride i tværretningen i forhold til hinanden .the known wedge does not provide any means to ensure that two wedges placed one on the other can move in the transverse direction relative to each other.

Kilen ifølge opfindelsen er til afhjælpning af denne ulempe ejendommelig ved, at en bestemt del af hver af tænderne i mindst én af rækkerne af kilefladefelter er forskudt en brøkdel af en tandbredde, fortrinsvis en halv tandbredde, i forhold til tænderne i de øvrige langsgående rækker af kilefladefelter, idet de med forskudte tænder forsynede rækker af felter har samme placering i forhold til de øvrige rækker ved ens betragtning af de to kileflader.The wedge according to the invention is to remedy this disadvantage in that a certain part of each of the teeth is displaced in at least one of the rows of wedge surface fields by a fraction of a tooth width, preferably half a tooth width, relative to the teeth in the other longitudinal rows of wedge surface fields, the rows of fields provided with displaced teeth having the same position with respect to the other rows in equal consideration of the two wedge surfaces.

Derved opnås, at der ved hjalp af rækken med forskudte tander sikres mod skridning i tvårretningen, da tanderne i denne rakke ved en tværforskydning vil støde mod tanderne i en af de øvrige rakker. Desuden opnås ved den navnte placering af rækkerne af tander, at man bliver fri for at skulle kontrollere, om kilerne vender med den rigtige side mod hinanden.In this way it is achieved that by means of the row of staggered teeth, it is secured against sliding in the transverse direction, as the teeth in this rack will bump against the teeth in one of the other racks. In addition, the named placement of the rows of teeth results in being free to check whether the wedges are facing the right side.

Opfindelsen skal nærmere forklares i det følgende under henvisning til tegningen, hvor fig. 1 viser en støtte- og udfyldningskile ifølge opfindelsen, set oppefra, fig. 2 kilen set fra enden, og fig. 3 et langsgående snit gennem kilen.The invention will be explained in more detail below with reference to the drawing, in which 1 is a top plan view of a support and filling wedge according to the invention; FIG. 2 shows the wedge from the end, and fig. 3 is a longitudinal section through the wedge.

Den i fig. 1 viste kile har to konvergerende kileflader 2, 3, som hver har fordybninger 4a, 4b, der i hovedsagen er anbragt i et skakbrætmønster. Fordybningerne 4a i den ene kileflade 2 rager ind i mellemrummene mellem fordybningerne 4b i den anden kileflade 3. Hver af fordybningerne 4a i kilefladen 2, og som fortrinsvis har et rektangulært tværsnit, afgrænses dels af sidevægge S, som står vinkelret på kilens symmetriplan, dels af en bunddel 6, hvis væk fra fordybningerne 4a vendende flade er en del af den modsatte kileflade 3. Tilsvarende for fordybningerne 4b og disses bunddele i forhold til kilefladen 2.The FIG. 1, there are two converging wedge surfaces 2, 3, each having recesses 4a, 4b, which are generally arranged in a checkerboard pattern. The recesses 4a of one wedge surface 2 project into the spaces between the recesses 4b of the other wedge surface 3. Each of the recesses 4a of the wedge surface 2, which preferably has a rectangular cross-section, is delimited partly by side walls S which are perpendicular to the plane of symmetry and partly of a bottom part 6 whose surface facing away from the recesses 4a is part of the opposite wedge surface 3. Corresponding to the recesses 4b and their bottom parts relative to the wedge surface 2.

Claims

The wedge face panels 7, which lie in racks on the wedge surfaces 2 and 3, for example in three racks, are provided with transverse grooves or tendons 8, preferably with a sawtooth profile, the sawdust points towards the thickest end of the wedge. 8 As a result of these teeth, two or more wedges will be able to slide longitudinally on top of one another as the wedges' tips point each way. Due to the fact that part of each of the teeth in at least one of the rows of wedge surface fields 7 is offset by a fraction of a tooth width, the wedges will also not be able to move in the transverse direction relative to each other, since the displaced parts of the teeth in falls would abut the not-shot teeth. The displaced tooth parts are preferably displaced half a tooth width. He can advantageously let the rows of teeth 7 provided with staggered teeth have the same relative position when considering the two wedge surfaces, thereby completely freeing them from having to check if they are facing the right side upwards. It is preferably the middle or longitudinal rows of fields 7 which have offset tooth portions. Preferably, the offset portion of each of the teeth has a length measured 1 crosswise, corresponding to the entire width of the field 7 minus twice the thickness of the cradles 5 defining the recesses 4a, 4b. Advantageously, in order to facilitate the arrangement of the wedge surface panels 7 relative to each other, in the transition region between staggered and non-staggered tooth parts, a substantially V-shaped incision can be made in the wedge surface, where the V is 2-15 °, preferably 10 ° - see FIG.

2. This will allow the wedges to move only slightly in the transverse direction. The wedges are preferably made of plastic, for example by injection molding. The required plastic has been reduced to a minimum without this being at the expense of the strength of the wedges. Claims.
