ABSTRACT:
An anchoring device for anchoring a post into a ground surface made of granular material. The anchoring device is particularly well adapted to anchor a beach umbrella into the sand. The anchoring device has a sleeve section and an integrally extending insertion section. The sleeve section defines a post receiving channel adapted to receive the post. The insertion section has a conically tapering configuration. A pair of parallel insertion threads extends integrally from the outer surface of the insertion section and a portion of the sleeve section. The parallel threads facilitate the insertion into the sand and further stabilize the device. A locking sleeve extends integrally from the sleeve section adjacent its top end. The locking sleeve defines a threaded locking channel that emerges into the post receiving channel. A handle sleeve also extends integrally from the sleeve section. The handle sleeve is diametrically opposed to the locking sleeve. The handle sleeve defines a handle channel that also emerges into the post receiving channel. A locking-handle component having an "L"-shaped configuration and a threaded end section are adapted to be slidably inserted into the handle sleeve channel and threadably inserted into the locking channel for respectively acting as a handle and releasably locking the post into the post receiving channel.
