Definitions

  • the present invention relates to a post system for the attachment of posts to a substrate.
  • posts and rods stands or the like are to be understood.
  • these are bollards, bollards, railings, safety barriers, signposts, supports for signs or trash cans, or bike racks.
  • the underground may be, for example, a carriageway, a sidewalk or a place, outdoors or inside a building.
  • Such a problem solves a post system with the features of claim 1, a closure with the features of claim 4, a ground anchor with the features of claim 7, a fastening with the features of claim 10 and a predetermined breaking screw with the features of claim 13.
  • Post and ground anchors may be metal, such as steel, stainless steel, aluminum or the like, or plastic or composite, or a combination thereof.
  • a lock can be provided at the top and a bolt, which is operatively connected to the latter by a tension element, which engages in the closing position by engaging the closure in a bolt-receiving recess in the floor anchorage.
  • the closure is releasably connected by a plug-and-turn connection, such as a bayonet lock or a Storz coupling, with the mating closure.
  • the post further has a centrically arranged guide pin on the underside with a central shaft and the ground anchor has on the upper side furthermore a central recess with a central bore complementary to the central bore.
  • the guide pin has at least one laterally projecting from the shaft to the outside elevation and the central recess has at least one complementary to the collection radial recess which extends laterally of the central bore to the outside.
  • the guide pin is longer than the closure elements and this projecting in the insertion direction. Also advantageous is the design of smooth transitions between the central shaft of the guide pin and the projections provided thereon, as well as between the central bore of the mating closure and the subsequent radial recesses, since then the alignment with little effort, almost as if done by itself ,
  • the guide pin has a tip, which is realized by a conical converge of the circumference of the shaft. There is no survey in the area of the peak. Following the top, an area with at least one elevation connects. Alternatively, two, three, four or more surveys may be present.
  • the number of elevations of the guide pin corresponds to the number of radial recesses in the counter-closure. However, an uneven number is also conceivable.
  • a shaft area adjoins which has no elevations. This area allows the guide pin, and thus the whole closure, to be rotatable after insertion into the counter-lock.
  • the counter-closure has an upper-side area with the recesses complementary to the guide pin, and an underlying area which is designed such that it does not hinder the guide pin with its elevations from rotating about its longitudinal axis.
  • the at least one radial recess is formed such that it serves as a guide for the at least one elevation during insertion of the guide pin into the central recess and serves as BolzenabilityausEnglishung after making the plug-and-turn connection. That after rotation into the locking position, the bolt engages in one of the at least one radial recesses.
  • the longitudinal center axis of the bolt lies on a circle about the longitudinal central axis of the guide pin, which lies within the region of the radial recesses. This embodiment has the advantage that no additional recesses for receiving the Bozen must be provided in the counter-closure.
  • the bolt may be arranged such that its longitudinal central axis lies on a circle about the longitudinal central axis of the guide pin, which lies within the range of peripheral recesses which are provided for receiving closure elements.
  • the bolt is in the closed state of the post in an insertion of the peripheral recesses, since this is occupied only during the introduction of the closure elements of the post in the mating closure by the closure elements and is unoccupied in the closed state.
  • the arrangement of the bolt in a peripheral region has the advantage that larger torques can be absorbed, which act on the post about its longitudinal central axis, or that of the guide pin.
  • a displaceable locking core is arranged in the ground anchoring, which closes in an unconnected to the post state, the upper anchoring on the bottom anchoring recesses upwards and which can be depressurized by the guide pin and / or other elements of the plug-and-turn connection. Closing the top recesses prevents the floor anchoring from becoming clogged. For example, prevents leaves, snow or ice from clogging the recesses, making it difficult to insert the post.
  • the locking core can be made of metal or plastic.
  • a locking core made of metal is particularly resistant to wear, whereby a long life can be achieved.
  • a metallic locking core is made of stainless steel or aluminum.
  • a locking plastic core has the advantage that the Plastic has a different thermal expansion coefficient than the surrounding housing of the mating closure. This prevents or reduces the risk of icing at temperatures around or below freezing.
  • a closure core is based on a polycarbonate blend.
  • the locking core is pressed by a spring element in the upper side recesses up. For example, by a spiral or leaf spring or other known from the prior art spring elements.

After the separation of the screw head 42 from the threaded shaft 40, the four recesses form a square in cross section, which can be taken with a corresponding complementary tool.
  • cross sections may be realized, such as those with three, five, six or more edges.
  • oval cross-section can be realized.
  • a predetermined breaking screw instead of the recesses 44, which extend substantially on the surface of the screw shaft, also have recesses which extend through the screw shaft.
  • a slot screwdriver can be inserted to unscrew the screw shaft from its recording.
  • two or more such continuous recesses may be arranged regularly or irregularly distributed with respect to the circumference of the screw and thus form different engagement shapes for a corresponding tool after detaching the screw head. For example, two relative to the longitudinal center axis L mutually perpendicular, continuous recesses, after the separation of the screw head forms an engagement form for a cross-head screwdriver.
  • FIG. 9 shows a partial sectional view of the post system by a locking pin 90 with inserted bollard 1.
  • the locking pin 90 has a shaft which has a circumferential flange 91 at a distance from the two free ends. One of the two free ends is tapered and the other free end has a clamping member 92 in the mold a rubber ring, which is arranged in a groove.
  • the bolt 90 is received in the assembly in a designated locking pin receptacle 125 in the closure 12 and secured by two screws.
  • retaining elements of a different number may be used.
  • a further locking pin receptacle 112 is provided, in which the free end of the locking pin 90 can be received with the clamping element.
  • the diameter of the locking pin receptacle 112 in the bottom 11 is dimensioned such that the locking pin 90 is clamped by the clamping element in the locking pin receptacle 112 and can not fall down by gravity. Only when the bottom 11 is separated from the closure 12, the locking pin 90 can fall down into a recess provided in the mating closure 20. In the illustrated embodiment, the bolt 90 falls into one of the radial recesses 2021 of the central recess 202.
  • the bolt can fall into a separate recess or into one of the peripheral recesses 201.
  • larger torques can be absorbed or with a smaller bolt the same torque.
