Beach umbrella anchoring apparatus |
摘要 |
The present invention is an apparatus and method for anchoring the central support pole of a beach umbrella in the sand at a beach. The present anchoring apparatus includes a length of tube having a lower edge forming an opening at its lower end and a clamping means at its other end. The other or upper end of the tube is operatively adapted to permit the lower end of a beach umbrella support pole to be inserted there through, and the clamping means is suitable to lock in place the lower end of a support pole so inserted. The edge at the lower end of the tube is preferably serrated and intended to cut into the sand beach. The clamping means may include a threaded hole formed through the wall at the upper end of the tube and a screw that can be hand tightened through the threaded hole to apply a clamping force against the lower end of an umbrella support pole inserted into the upper end of the tube.
