  • Patent number: 5362270
    Abstract: A surfboard leash retainer for removably securing the free or surfer attachment end of a surfboard leash to the surfboard when the surfboard is being transported, not in use or stored. The retainer takes the form of either a fixed-in-place or removable retainer positioned near the forward most end of a surfboard while the attached end of the surfboard leash is fixedly attached near the rearmost end of the surfboard. The fixed-in-place retainer is either adhered to the board as an add-on or attached to the board as a step of the construction of the board. The removably attached retainer can be in the form of a resilient suction cup. The upper or leash retainer surface includes a channel with a restricted opening through which the leash can be forced and held in the channel by the restriction. The retainer or leash or both are constructed of a resilient material to allow the leash to be easily forced past the restriction into the channel and held thereby until forcibly removed.
