Abstract

A mechanism for anchoring umbrellas that includes a tubular outer member and a helical assembly at the lower end that is driven into the ground through manually imparted rotation through the use of a gear box and handle or battery powered electric motor. Stabilizing members protrude into the ground by the action of a releasable spring. The spring acts on an inner shaft that is co-axially housed within an outer tubular member. The inner shaft is rigidly mounted at its lower end to a platform member from which the stabilizing members are pivotally mounted. The stabilizing members protrude outwardly and snuggly through angular openings preventing the sand or soil from entering.

Claims

1. A mechanism for anchoring umbrellas having a shaft, comprising:

A an elongated outer tubular member having an upper end and a lower end and further including a plurality of angled openings at said lower end;

B means for removably holding said shaft mounted at said upper end;

C an inner shaft coaxially disposed within said elongated outer tubular member and extending substantially along the entire length of said outer tubular member and said inner shaft further including two ends and one of said ends of said inner shaft member including a gear termination;

D gear means for imparting a rotational force to said gear termination;

E a helical assembly rigidly mounted to the other end of said inner shaft member so that said helical assembly is driven into the ground when said gear means impart a rotational force to said inner shaft; and

F spring-loaded stabilizing means for providing structural stability to said mechanism and further including a plurality of stabilizing members that protrude from the interior of said outer tubular means snuggly passing through said angled openings and said stabilizing members being made out of a resilient material.

2. The mechanism set forth in claim 1 wherein said spring-loaded stabilizing means includes a spring member co-axially disposed within said outer tubular member and further including pin means for compressing said spring member and retracting said stabilizing members within said outer tubular member.

3. The mechanism set forth in claim 2 further including:

G retaining means for releasably keeping said spring member in compressed state.

4. The mechanism set forth in claim 3 further including a longitudinal slot through which said pin means protrude outwardly and said retaining means includes a termination of said slot as an invert "J" at the end closest to said upper end of said outer tubular member.

5. The mechanism set forth in claim 4 wherein said gear means includes electric motor means for imparting said rotational force.

6. The mechanism set forth in claim 3 wherein said retaining means includes a hook member pivotally mounted to said outer tubular member so that said hook member cooperatively engages with said pin means to releasably keep said spring member in compressed state.

7. The mechanism set fourth in claim 6 wherein said gear means includes electric motor means for imparting said rotational force.

8. The mechanism set forth in claim 3 further including platform means for pivotally supporting said stabilizing members and said platform means adapted to travel within said outer tubular member.

9. The mechanism set forth in claim 8 further including means for sealing the interior of said outer tubular member between said upper end of said outer tubular member and said angled openings and substantially adjacent to the latter.

10. The mechanism set forth in claim 9 wherein said gear means includes electric motor means for imparting said rotational force.

11. The mechanism set forth in claim 5 wherein said gear means include battery means for powering said electric motor means.

12. The mechanism set forth in claim 11 wherein said battery means are of the rechargeable type.

13. The mechanism set forth in claim 7 wherein said gear means include battery means for powering said electric motor means.

14. The mechanism set forth in claim 13 wherein said battery means are of the rechargeable type.

15. The mechanism set forth in claim 10 wherein said gear means include battery means for powering said electric motor means.

16. The mechanism set forth in claim 15 wherein said battery means are of the rechargeable type.
