Definitions

  • the invention relates to an anchor rail with the features of the preamble of claim 1.
  • Anchor rails are typically sunk flush in a floor or a wall made of concrete and are used to fasten objects, such as machines, with the help of hammer-head screws, for example.
  • "Sunk flush" means that the anchor channel is embedded in the concrete and one side of the anchor channel is flush with a surface of, for example, the concrete.
  • the anchor rails are cast in concrete on three sides.
  • the anchor rails typically have a C-profile rail, ie a square or rectangular tube profile with a continuous longitudinal slot in a transverse center of one side.
  • anchor rails are manufactured or extruded from sheet steel or sheet metal in general, although materials other than metal are also possible.
  • Patent FR 1.544.762 discloses a T-head bolt for fastening cover elements to pillars of utility vehicle bodies.
  • the T-head bolt has a shank with a thread at one end and a parallelogram-shaped bolt head at the other end.
  • the screw head can be inserted through a slot in one of the posts and rotated to engage behind the post.
  • Adjoining the screw head the shank of the known hammer-head screw has, on a circumference opposite one another, two semi-crescent-shaped projections, viewed axially, with axially parallel ribs on their outer surfaces, which press against the edges of the slot in the post when the screw head is rotated, thereby holding the hammer-head screw in place increase a longitudinal direction of the post.
  • the object of the invention is to propose an anchor rail with an anchor with an improved hold in a longitudinal direction of a C-profile rail of the anchor rail. According to the invention, this object is achieved by the features of claim 1 .
  • the anchor rail according to the invention has a C-profile rail and an anchor with an anchor head which can be brought into a rear grip in the C-profile rail.
  • a "C-profile rail” is a tubular rail with a particularly square or rectangular cross-section and a longitudinal slot in one side.
  • the anchor head is in particular rectangular or in the form of a parallelogram, it also being possible for the anchor head to have other shapes, for example square, hexagonal or round.
  • the anchor head can be inserted into the C profile rail through the longitudinal slot in the C profile rail, aligned in a longitudinal direction of the C profile rail, and rotated to grip behind the C profile rail, so that it does not protrude in the axial direction perpendicular or transverse to the C profile rail can be pulled out of the C profile rail.
  • the anchor head can also be introduced into the C-profile rail from one end, so that an anchor shank reaches through a longitudinal slot in the C-profile rail.
  • the anchor can be designed in the manner of a screw with a shank that passes through the longitudinal slot of the C-profile rail and preferably has a screw thread and a head in the manner of a screw head that forms the anchor head.
  • the anchor head can also have a nut thread into which a shank having a screw thread or screw threads at both ends can be screwed. The list is exemplary and not exhaustive.
  • the anchor head On one peripheral side, the anchor head has first serrations with first cutting edges offset one behind the other in a circumferential direction, the first serrations preferably being arranged in a limited peripheral section of the anchor head.
  • the first cutting edges have a radial distance from a longitudinal axis of the anchor that increases from serration to serration in one circumferential direction of the anchor head.
  • the “longitudinal axis of the anchor” is, for example, a longitudinal axis of an anchor shank or a nut thread of the anchor head.
  • the first cutting edges are located on an imaginary curved lateral surface that is eccentric to the longitudinal axis of the armature, with a concave side of the lateral surface facing the longitudinal axis of the armature.
  • a radial distance between the lateral surface and thus the first cutting edges from the longitudinal axis of the armature increases in one circumferential direction.
  • the first cutting edges of the serrations that follow one another in one circumferential direction of the anchor head press ever more strongly from the inside against the side walls of the C-profile rail and preferably form deeper and deeper into the inside of the side walls of the C-profile rail. This achieves a good hold of the anchor in the C-profile rail in its longitudinal direction.
  • the anchor head of the anchor according to the invention preferably has first serrations and first cutting edges arranged opposite one another axisymmetric to the longitudinal axis of the anchor, which press against opposite side walls of the C profile rail from the inside when the anchor head is rotated in the C profile rail and preferably press into the inner sides of the opposite side walls of the C profile rail.

  • the anchor head has two or more serrations, the cutting edges of which have a smallest and equally large radial distance from the longitudinal axis of the anchor. That is, the anchor head has at one end of the peripheral section or the two opposite peripheral sections, in which the anchor head has the first serrations, two or more serrations, the cutting edges of which have the same radial distance from the longitudinal axis of the anchor. These two or more first serrations are adjoined in one circumferential direction by further serrations, the first cutting edges of which have a greater radial distance from the longitudinal axis of the armature in one circumferential direction from serration to serration.
  • the first serrations improve an engagement, in particular a cutting of the first cutting edges on the insides of the side walls of the C-profile rail when the anchor head is rotated in the C- profile rail.
  • the first serrations, the cutting edges of which have the same and smallest distance from the longitudinal axis of the anchor first come into contact with the respective inner sides of the side walls.
  • the distance between a first cutting edge that is furthest away from the longitudinal axis of the armature is preferably greater than half the inside width of the C profile rail.
  • the distance between several, possibly also all, first cutting edges from the longitudinal axis of the armature is greater than half the inner width of the C-profile rail in order to ensure that at least the first cutting edge, which has the greatest radial distance from the longitudinal axis of the armature, during rotation of the anchor head in the C profile rail comes into contact with the side wall of the C profile rail from the inside.
  • first cutting edges which are less far away from the longitudinal axis of the anchor, also come into contact with the side wall of the C-profile rail from the inside.
  • a preferred embodiment of the invention provides sawtooth-shaped first serrations.
  • a likewise preferred embodiment of the invention provides that the first cutting edges run obliquely at a preferably acute angle to the axial planes of the armature.

  • the rotation of the anchor head in the C-profile rail causes an axial force on the anchor head if the first cutters rest on the inside of the side walls of the C-profile rail or are shaped into the inside of the side walls.
  • the anchor head "inevitably” moves in the direction of the longitudinal slot of the C-profile rail when rotating about the longitudinal axis, in particular until the anchor head comes into contact with rail lips between which the longitudinal slot is formed. In particular, the anchor head is braced against the rail lips.
