Abstract

An edging element for playing fields and sports installations has an elongate elastic profile top and a strip for anchoring the edging element inside of the profile top in a concrete slab in interlacing relationship with a straight reinforcement rod. That anchoring strip extends along and projects from the elongate profile top and has a series of apertures distributed along at least one line parallel to the elongate profile top for receiving the reinforcement rod alternatively from different sides of the anchoring strip which is of sufficiently elastic material to form an interlacement with the straight reinforcement rod. The anchoring strip is made flat prior to its enlacement with the straight reinforcement rod but is interlaced with that straight reinforcement rod to have sections between successive apertures located alternatively at opposite sides of said straight reinforcement rod.

Claims

1. Edging element for playing fields and sports installations, comprising in combination:

an elongate elastic profile top; and

means for anchoring said edging element inside of said profile top in a concrete slab in interlacing relationship with a straight reinforcement rod, comprising an anchoring strip extending along and projecting from said elongate profile top, said anchoring strip having a series of apertures distributed along at least one line parallel to said elongate profile top for receiving said reinforcement rod alternatively from different sides of said anchoring strip being of sufficiently elastic material to form an interlacement with said straight reinforcement rod.

2. Edging element according to claim 1, wherein:

said anchoring strip has a thickening in the form of an elongate bead extending along a free edge thereof.

3. Edging element according to claim 2, wherein:

said apertures are located in said anchoring strip between said elongate profile top and said elongate bead.

4. Edging element according to claim 3, wherein:

said apertures are regularly spaced from each other.

5. Edging element according to claim 4, wherein:

said anchoring strip is flat prior to its enlacement with said straight reinforcement rod but is of sufficiently elastic material to have sections between successive apertures located alternatively at opposite sides of said straight reinforement rod.

6. Edging element according to claim 1, wherein:

said apertures are located in said anchoring strip between said elongate profile top and a free edge of said anchoring strip.

7. Edging element according to claim 6, wherein:

said apertures are regularly spaced from each other.

8. Edging element according to claim 7, wherein:

said anchoring strip is flat prior to its enlacement with said straight reinforcement rod but is of sufficiently elastic material to have sections between successive apertures located alternatively at opposite sides of said straight reinforcement rod.

9. Edging element according to claim 1, wherein:

said apertures are regularly spaced from each other.

10. Edging element according to claim 1, wherein:

said anchoring strip is flat prior to its enlacement with said straight reinforcement rod but is of sufficiently elastic material to have sections between successive apertures located alternatively at opposite sides of said straight reinforcement rod.
