The present invention related to weighted devices used for stabilization of beach umbrellas.
Several weighted devices for stabilization of beach umbrellas have bee taught in the prior art, however each of the devices has limitations overcome by the present invention. For example, U.S. Pat. No. 4,924,893 to Furey, includes a stiff pole for connecting to a weighted anchor which requires transport and limits the compatibility of the structure. Furey also includes a complicated connection system which limits the simplicity and ease of use of the device and requires a bag designed for carrying the device.
U.S. Pat. No. 7,946,305 to Mailman teaches a simplified weight, however the weights are suspended directly from the top of the umbrella, thus placing them directly overhead of the umbrella users and creating a potential hazzard. In addition, the placement of the weights, although increasing the weight of the umbrella also make the umbrella top heavy and thus more susceptible to falling.
U.S. Pat. Nos. 7,168,437 and 6,446,649 to Bigford teaches a metal ring for connection to the lower portion of the umbrella pole and the need for multiple weights adding unnecessary complexity. Connection directly to the lower portion fo the umbrella pole provides significantly less stability than the design of the present invention.
U.S. Pat. No. 5,452,877 to Riffle teaches placing the pole of the umbrella into a large bag. By securing the lower end of the pole, less stabilization is achieved. In addition, the size of the bag reduces the usable area under the umbrella.
The portable anchor of the present invention is attached to the upper portion of the umbrella pole with a hook-and-loop type fastener strap to provide ease of connection and increased stability. The flexible cord allows for a completely collapsible, compact and portable design.
Anchor bag 16, is connected to the pole 13 of the umbrella 10 by hook-and-loop type fastener strap 17 attached around the pole 13 above the runner 15. Inelastic cord 18 connects the hook-and-loop type fastener strap 17 to the anchor bag 16.
As better illustrated in
Because the distal end 17 of cord 16 is attached to the upper end of pole 13, tension will be maintained on cord 16 so that the cinching of bag 16 is maintained by the supporting action of the umbrella 10.

As illustrated in
The weight of the material in bag 16 will stabilize umbrella 10 against low to medium winds. Once filled, bag 16 is cinched closed and placed on the ground at a distance from the bottom of pole 13 to provide an angle for supporting the umbrella 10. Tension is maintained on cord 18 by the wind pressure on the umbrella 10. The tension on cord 18 prevents loosening of the cord 18 within the hem 21 to prevent the bag 16 form opening and spilling its contents and thus reducing its weight and stabilizing effect.
Although the invention has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly to include other variants and embodiments of the invention which may be made by those skilled in the art without departing from the scope and range of equivalents of the invention. It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
