Definitions

  • the invention relates to a locking element formed from a metal band for the production of a releasable connection of adjoining surface elements, for example of metal parts forming a floor covering for carriageways, the locking element having on both sides pointing downward, spaced apart and opposite leg-like approaches , which engage in recesses in the surface elements, and pliers for releasing and removing the locking element.
  • the floor coverings formed from the surface elements also serve, among other things, as runways for aircraft and must therefore be secured against displacement. For this purpose, they are provided with webs on their underside, which are pressed into the soil below by a shaking process.
  • leg-like approaches are directed outwards.
  • the leg-like approaches can be bent so far out that they can no longer be pulled out of the recesses of the surface elements, so that a later replacement of the surface elements in question is no longer possible or at least very difficult.
  • leg-like projections designed as hook-shaped projections are conical in such a way that the hook-shaped projections have only a line contact with the surface elements to be connected, so that the slightest displacement of the locking element relative to the surface elements to be connected leads to the fact that there is no longer sufficient cohesion between the individual surface elements.
  • the invention has for its object to provide a locking element that does not have the disadvantages of the known locking element and ensures both a secure cohesion of the interconnected surface elements and an easy replacement of individual surface elements.
  • the solution to the problem is in a locking element formed from a metal band of the type mentioned above that the leg-like approaches run parallel to each other, so that the locking element has a U-shaped cross-section in its upper region, the distance between the two leg-like approaches from each other somewhat is greater than twice the wall thickness of the outer webs of the surface elements and the length of the leg-like Approaches is slightly larger than the height of the outer webs of the surface elements; and that the ends of the leg-like approaches are crimped inwards.
  • the locking element according to the invention is capable of elastically absorbing any vertical movements of individual surface elements without being released from its locking.
  • the leg-like approaches are chamfered on one side in such a way that the width of their lower edge is less than half their width in the upper region; and the ends of the leg-like lugs are flanged inwards such that the length of each flanged end of the leg-like lugs is greater than half the distance between the two leg-like lugs from one another, so that the locking element has a closed U-shaped cross section at its lower end.
  • the webs of the interconnected surface elements are completely encompassed by the locking element.
  • the two leg-like approaches are provided with a hook-shaped projection formed by a flanging. These hook-shaped projections can be gripped by means of a suitable tool and the locking element can be opened by exerting a tensile force on the hook-shaped projections.
  • a pair of pliers is used to open the locking element, the two front ends of the pliers legs being offset from one another are and extend only about a third of the width of the pliers, the front ends of the pliers legs are each at the edge of the pliers; and when the pliers are closed, the front ends of the pliers legs have a gap which corresponds approximately to the outer shape of the locking element; and also each front end of the pliers legs is provided with a strip-shaped thickening, the width of which is slightly smaller than the distance of the hook-shaped projections from the locking element.
  • the strip-shaped thickenings engage behind the hook-shaped projections of the locking element, so that when the pliers legs are spread out, the locking element is opened and can be removed.
  • the adjacent surface elements 1 and 2 are connected by a locking element 3 in such a way that the locking element 3 encompasses the outer webs 4 and 5 of the surface elements 1 and 2 (see FIG. 2) .
  • the surface elements 1 and 2 are provided with recesses 6.
  • the leg-like lugs 7 of the locking element 3 run parallel to one another, their distance A being greater than twice the wall thickness S of the outer webs 4 and 5 of the surface elements 1 and 2.
  • the length L of the leg-like lugs 7 is somewhat greater than the height H of the Crosspieces 4 and 5.
  • the crosspieces 4 and 5 are somewhat shortened at their upper end, so that the locking element 3 does not protrude from the surface elements 1 and 2.
  • the leg-like lugs 7 of the locking element 3 are chamfered on one side in such a way that the width b of their lower edge is less than half their width B in the upper region.
  • the leg-like projections 7 are each provided with a hook-shaped projection 10 and 11, the hook-shaped projections 10 and 11 being formed by an offset in the central part of the leg-like projections 7.
  • each lower end 12, 13 is provided with a strip-shaped thickening 17, 18 which engages behind the hook-shaped projections 10 and 11 when the pliers are placed on the locking element 3.
