Description

RELATED APPLICATION

This application claims priority to U.S. Provisional Applications Ser. Nos. 60/686,940 and 60/686,939, filed Jun. 3, 2006, which are incorporated herein by reference in their entirety.

FIELD OF INVENTION

The present invention relates generally to improved beach umbrellas and similar products that are used at a beach, picnic, or outdoors generally having enhanced utility. More specifically, the present invention relates to a new beach umbrella having an improved anchoring means and an air pressure venting means, resulting in enhanced stability.

BACKGROUND OF INVENTION

There are as many cases of skin cancer as there are of all other cancers combined—about 1 million new U.S. cases per year. Indeed, the incidence of melanoma, the most deadly form of skin cancer, has steadily increased about 3% per year since 1981. The primary cause of skin cancer is chronic unprotected exposure to the sun and intense irregular exposures such as those that occur at the beach. Further, sun exposure has been shown to cause premature aging of the skin. Skin cancer prevention and education efforts promote seeking shade, covering up and using sunscreen with SPF 15 or higher and both UVA and UVB protection.

Beach umbrellas are often used to provide shady areas on sunny beaches. However, standard beach umbrellas are heavy, and cumbersome with low stability. What is needed is an improved means to anchor beach umbrellas against being overturned and a means to reduce the effect of sudden or unexpected gusts of wind.

The following are provided as examples of existing art:

Farley, U.S. Pat. No. 3,456,661, discloses an umbrella having in addition to the normal umbrella covering a plurality of tapered gores forming flying vents to expel air horizontally and relieve air pressure to provide aerodynamic stability.

Ryder, U.S. Pat. No. 4,804,008, discloses an umbrella having vents that are sandwiched to and perforate the fabric cover of the umbrella.

Jacinto et al., U.S. Pat. No. 5,152,495 discloses a mechanism for anchoring a beach umbrella having an outer tubular member stabilizing members, an inner shaft and a helical assembly at the lower end of the outer tubular member. The end is driven into the ground through manual rotation via a gear box and handle or through a battery powered electric motor.

Tizzoni, U.S. Pat. No. 5,156,369 discloses a ground anchoring means for attachment to the pole of a beach umbrella. The ground anchoring mechanism comprises a hollow cylindrical member having a rod rotatably supported therein. A spiral screw is attached to one end and the other end is attached to a handle rotator.

Hall et al., U.S. Pat. No. 5,293,889, discloses a beach umbrella having three sections. The umbrella is attached to the upper section. The lower section includes a plurality of pivotally mounted handles upon its upper collar and a screw thread on the end portion of the lower section. The sections are fixed together with a latch means.

Gibson, U.S. Pat. No. 6,199,569, discloses an umbrella anchoring means. A securing means at one end of the anchor pole secures the covering means to the anchor pole. A bit is fastened to the other end. The bit has a curved thread for digging in response to rotation of the pole. A pivot member is mounted to the pole and is connected to a handle. Rotation of the handle rotates the anchor pole. The distal end of the bit includes an elongated spike member. The bit also has at least one blade helically disposed therein.

You, U.S. Pat. No. 6,520,193 and 6,571,814, discloses vented umbrellas.

Brooks, III, U.S. Pat. No. 6,715,503, discloses a beach umbrella having an internal anchoring structure. As disclosed, the beach umbrella includes a post having a lower end for insertion in to the ground and an upper end for supporting an umbrella top. There is an integral spiral shaped anchoring structure. Retractable levers are attached along the post.

While these devices fulfill their respective, particular objectives and requirements, the need remains for a stable, light weight, beach umbrella that is easy to set up. Accordingly, there exists a need in the art for a beach umbrella with such features. The present invention is designed to fulfill these needs and overcome the problems of the prior art.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring now to the drawings, wherein like reference numerals indicate like elements, in FIG. 1 there is shown an embodiment of the beach umbrella or the like which may be of any desired size. As illustrated, shaft 10 comprises two ends. First end of shaft 10 is removably attached to canopy 12. First end of shaft 10 is tubular. Auger 14 is integrated with second end of shaft 10. There are many types of materials known by those of ordinary skill in the art, which could serve as appropriate composition of shaft 10. Examples of such materials include plastic, metal and the like. In a preferred embodiment shaft 10 is aluminum or titanium. Ring clip 16 is attached to shaft 10. In a preferred embodiment, ring clip 16 is attached on or about the midpoint of shaft 10. Ring clip 16 enables the removable attachment of items such as camera, bags, purse, ice chest and the like by way of an attaching means such as a clip or carabiner or the like. In an alternative embodiment, attaching means is a lockable attaching means. A first end of canopy pole 18 is connected to canopy 12. A second end of canopy pole 18 inserts into the first end of shaft 10 and is secured by lever 40.

FIG. 2 illustrates a carrying means 2. The embodiment shown comprises first pocket 20 for carrying a variety of beach paraphernalia including but not limited to a towel or blanket, second pocket 22 for carrying the beach umbrella of the present invention, reinforcing element 24, shoulder strap 26, and handle 28.

FIGS. 3 and 8-12 illustrate a close up view of auger 14. Auger 14 comprises a spiral flange. As illustrated, shaft 10 and auger 14 are an integrated, cohesive unit. Preferably the spiral flange is widest at the top and then tapers to a point at the end. There are many types of materials known by those of ordinary skill in the art, which could serve as appropriate composition of auger 14. Examples of such materials include plastic, metal and the like. Depending on the composition of the auger, the auger may be solid or have a hollow center. In a preferred embodiment, the spiral flange of auger 14 is a solid plastic or a reinforced fiberglass composite, such as a nylon-reinforced fiberglass composite.

FIGS. 4 and 5 illustrate alternative embodiments of inserting means. The embodiment illustrated in FIG. 4 comprises attached handle 42, while the embodiment illustrated in FIG. 5 comprises removable cross bar 50 and hole 52 for removable cross bar 50 insertion. There are many types of materials known by those of ordinary skill in the art, which could serve as appropriate composition of handle 42 or removable cross bar 50. Examples of such materials include plastic, metal and the like. In a preferred embodiment handle 42 or removable cross bar 50 is aluminum or titanium.

Alternatively, the umbrella may not comprise a handle or crossbar. Instead, the umbrella may be inserted into the sand by gripping the lower part of the shaft 10 and turning it clockwise such as to screw it into the sand. The spiral flange of the auger 14, as seen more specifically in FIGS. 8-12, permits the auger to be easily inserted into sand. Moreover, the auger 14 may be easily removed by turning the shaft 10 counter-clockwise such as to unscrew it from the sand.
