Definitions

  • the invention relates to a dowel for anchoring synthetic fibers of an artificial turf in the floor and a device for inserting the anchor into the floor.
  • the invention provides a dowel in which the synthetic fibers are similar to a Thread into a needle or wool into a crochet hook.
  • the dowel with the synthetic fibers are pressed into the ground, the synthetic fibers being U-shaped fold.
  • the assembly point is located on the dowel.
  • the dowel anchors the synthetic fibers even at a limited depth of only approx. 10, for example cm with sufficient hold against pulling out in the floor.
  • the holding values of the synthetic fibers in the ground are several times lower in spite of the reduced insertion depth Comparison with synthetic fiber bundles, which are inserted into the floor without dowels.
  • the dowel also supports natural grass, the roots of which are those with the dowel in the ground loop around anchored synthetic fibers.
  • Another advantage of the dowel according to the invention is that this anchors the synthetic fibers to the ground with a high holding force, if roots of natural grass sown around the synthetic fibers, the synthetic fibers in the Have not yet wrapped around the floor.
  • the sports field is therefore immediately after Setting the artificial turf usable, at least as far as it is the artificial turf and not the Natural grass affects. In any case, the sports field is therefore earlier after seating of artificial turf and sowing of natural turf can be used if the artificial turf with the dowels according to the invention is anchored in the ground.
  • An embodiment of the invention has a slot for threading the synthetic fibers Through hole, an eyelet, a hook or the like.
  • This device for attaching the synthetic fibers is preferred so arranged on the dowel that a tensile stress on the synthetic fibers the synthetic fibers do not exert a tilting moment on the dowel about a transverse axis of the dowel, to avoid turning the dowel inserted into the floor.
  • a force application point the synthetic fibers are therefore preferably located behind a longitudinal center of the dowel.
  • a further development of the dowel according to the invention has one or more pull-out blocking elements for example in the form of diagonally protruding backwards and outwards, spring pawls. These are when the expansion anchor is pressed into the Pressed inwards and spread out after pushing in the anchor Floor, whereby they penetrate the floor and thereby prevent the plug from being pulled out anchor in the ground. It is also possible to screw the dowel preferably large thread depth or with circumferential ribs that form the dowel anchor it to the floor by positive locking.
  • the dowel is preferably provided with a device with which it can be detachably attached to one Device for inserting the dowel can be attached to the floor.
  • the device can be, for example, an axial hole in the dowel with which it can be attached to the Device can be plugged on.
  • the device according to the invention for introducing the dowel into the floor has a mandrel on which the dowel can be attached, for example.
  • the dowel is after Attach the synthetic fibers to the dowel and place the dowel on the mandrel with the Thorn pressed into the ground. Attaching the synthetic fibers to the dowel, putting them on the dowel on the mandrel and inserting the dowel into the ground can be done by hand or done mechanically.
  • the mandrel of the device projects into the ground above the dowel attached to it.
  • This has the advantage that the mandrel preforms a hole in the bottom, which makes the dowel when Inserting it into the ground is only slightly stressed. Damage to the particular Plastic dowels that affect its anchoring ability could be caused by the when the dowel is inserted into the floor avoided the dowel projecting.
  • the device according to the invention for introducing the dowel into the ground Device for specifying or limiting the insertion depth of the dowel.
  • This can be, for example, a scale on the mandrel on which the insertion depth of the dowel can be read is.
  • the mandrel can have a ring-shaped diameter widening or have a laterally protruding stop.
  • the dowel 10 according to the invention shown in FIGS. 1a-c is for anchoring Synthetic fibers of an artificial turf are provided in the ground.
  • the dowel 10 has a short, cylindrical plug body 12, which is located at a front or insertion end 14 tapered to a smaller diameter. On a side facing away from the insertion end 14 The dowel body 12 extends its diameter on a collar 16 with a rounded transition.
  • Four of this bundle 16 are distributed over the circumference arranged pawls 18 integral with the dowel body 12 obliquely to the rear and outside of the dowel body 12.
  • the pawls 18 are resilient, they are pressed radially inwards when the dowel 10 is pressed into the ground and spread radially into their original position after being pressed in.
  • the dowel body 12 is provided with a V-shaped transverse slot 20, which is open at the insertion end 14 and tapers towards the rear of the dowel 10.
  • a threading hole 22 which extends transversely through the dowel body 12 and which is open at one point on its circumference, so that the transverse slot 20 merges into the threading hole 22 without interruption.
  • the transverse slot 20 and threading hole 22 have a shape similar to a keyhole in the side view of the dowel 12 with a V-shaped widening Key bit ", which is formed by the V-shaped transverse groove 20.
  • the dowel body has a device for inserting the dowel 10 into the floor 12 a through axial hole 24 ( Figure 1b), which is at right angles in the threading hole 22 opens.
  • the embodiment of the invention shown in the drawing Dowel 10 is a plastic injection molded part.
  • FIGS. 2a-c show an embodiment modified from FIGS. 1a-c of an anchor 10 according to the invention. To avoid repetitions the differences are described below, otherwise the References to Figures 1a-c referenced. For the same parts become the same Reference numbers used.
  • the dowel 10 shown in FIGS. 2a-c has a threading bracket 26 instead of the Cross slot 20 and the threading hole 22.
  • the threading bracket 26 is integral with the dowel body 12, it is located on the side facing away from the insertion end 14 of the plug body 12.
  • the continuous axial hole 24 passes through the plug body 12 over its entire length and does not run openly in the widening transverse slot 20 from, as is the case with the dowel 10 shown in FIGS. 1a-c.
  • Dowel body 12 protruding threading bracket 26 has the advantage that when train on not shown in Figures 2a - c, threaded through the threading bracket Synthetic fibers do not have a moment on the dowel which rotates the dowel 10 about a transverse axis 10 is exercised, but on the contrary, such a move on by Threading bracket 26 synthetic fibers threaded the dowel 10 in its longitudinal orientation stabilized.
