  • Patent number: 10898748
    Abstract: A cord hook for fastening a jump mat to a trampoline frame includes a holding section for holding a first and a second loop end section of the cord loop and a fastening section for fastening the flexible band element, wherein a main tension vector (V) is defined by tension at the band element. The hook has a transition section connecting the holding section and the fastening section and is designed in such a way that a straight line (g) through the main tension vector (V) divides the holding space into a first partial space and a second partial space in such a way that, when the cord hook is used as intended, the first loop end section lies in the first partial space and the second loop end section lies in the second partial space. Also disclosed are a trampoline and a method for fastening the jump mat.
