ABSTRACT:
A rope anchor device for a swimming pool having a vinyl liner wherein a flat base plate has at least two integral stems projecting rearwardly from the plate and extending through the swimming pool wall. A nut is threaded on each stem at the back or outside of the swimming pool wall to mount the plate securely against the inside of the swimming pool wall. A rope anchor eyelet plate is in turn mounted on the base plate, with the linear clamped therebetween, by at least two threaded fasteners which engage the anchor plate and are threadably engaged in bores extending coaxially through the stems. The base plate can be made of cast and machined metal or injection molded plastic. Where the base plate is made of metal, the bores are internally threaded. Where the base plate is made of injection molded plastic, self-tapping screws can be used and hence the bores need not be internally threaded.
