Description
- The present invention relates to buoys and, more particularly, to spar buoys.
- A variety of buoys are deployed for various purposes in the waterways. One type of a buoy is a spar buoy or, also referred to as, a pencil buoy. The spar or pencil buoys are typically used for marking purposes in the waterways and usually include signage thereon. The spar buoys are deployed to remain afloat upright and include a solid cylindrical body with a lower portion and an upper portion. The lower portion is typically immersed under water and the upper portion is intended to protrude above the water surface. The upper portion is utilized for various waterways makings, such as speed limits, slow down signs and other directional or warning signage.
- The spar buoys come in various sizes. The size of the buoy deployed depends on various factors, including the surface area required for signage. The larger buoys require more material and, thus, are more costly. Additionally, it is more expensive to ship larger and heavier buoys. Therefore, it is desirable to have a larger buoy that is more cost-effective.
- According to the present invention, a partially flooding buoy includes a buoy body having a substantially cylindrical shape defining a cavity therein and a mooring mechanism attached to the buoy body to allow the buoy to be moored. The partially flooding buoy can be partially flooded with water after the buoy is deployed. In a preferred embodiment, the cavity is a substantially cylindrical opening passing through the buoy body. The cavity is adapted to accommodate ballast therein. The ballast can be added after the buoy is deployed and can be any type of weight, such as rocks or old chain or pieces thereof. The ballast is added as needed for the buoy to be properly deployed.
- In the preferred embodiment, the buoy includes at least one flooding opening to allow water to pass therethrough into the cavity. The flooding opening is formed within a lower portion of the buoy body to be submerged under water. In the preferred embodiment, the mooring mechanism includes a plate attached to the buoy body and a mooring ring for allowing the buoy to be attached to the mooring. The mooring is attached to the buoy body by at least two bolts to ensure sturdy attachment. Additionally, in the preferred embodiment, the buoy includes at least one handle to allow more convenient handling of the buoy, wherein the handle is an opening formed within the buoy body.

Thefirst bolt 40 extends through thecavity 20 andwalls 22. Thebolts buoy wall 22 and to the mooring plate, respectively, withbolt nuts 44. - In the preferred embodiment of the present invention, the
buoy 10 also includesflooding openings 46 formed within thebody wall 22 in thelower portion 16 thereof. Theflooding openings 46 allow water to pass therethrough into thecavity 20 to partially flood thebuoy 10. - In the preferred embodiment, the
buoy 10 also includeshandle openings 50 formed within theupper portion 14 of thebuoy body 12. Thehandle openings 50 are sized to allow a person to place his/her hand therein. - Referring to
FIG. 5 , in another embodiment of the present invention, themooring plate 34 includesholes 51 to allow the water to enter thecavity 20 of thespar buoy 10 therethrough. In the embodiment, theflooding openings 46 shown inFIGS. 1-3 do not need to be formed. - In operation, as the
buoy 10 is deployed, it is placed in the water with thelower portion 16 of thebuoy body 12 being submerged under the water, as shown inFIGS. 4 and 5 . Thebuoy ring 36 is attached to amooring chain 52, as shown inFIG. 1 . The water floods a portion of the buoy through theflooding openings 46, as shown inFIG. 4 , or through theholes 51 formed in themooring plate 34, as shown inFIG. 5 . Once thebuoy 10 is placed in the water and chained/moored, theballast 56 is added, as shown inFIG. 4 . Theballast 56 can be comprised of either stones or old chains or any other weight. The ballast is added until the buoy is properly deployed. Thehandles 50 can be used to place the buoy in the water. - The
buoy body 12 in the preferred embodiment is fabricated from SOFTLITE® material fabricated by Gilman Corporation of Gilman, Conn. However, the buoy can be manufactured from other buoyant materials. - One major advantage of the present invention is that the buoy of the present invention self-rights after deployment. Once the buoy is placed in the water and ballast is added, the buoy self-rights with the proper amount of ballast. Additionally, the buoy does not need to be removed from the water to adjust the amount of ballast, the additional weight, either stones or chain or any other heavy object(s), can be added after deployment into the cavity of the buoy.
- Another major advantage of the present invention is that larger signage area is available without adding cost to the buoy. Thus, larger buoy can be manufactured with less material than a solid buoy, thereby minimizing costs of the larger buoys.
- A further major advantage of the present invention is that the hollow buoy of the present invention is significantly lighter that the solid buoy and can be shipped at much lower costs.
- Yet a further advantage of the present invention is that the partially flooding buoy of the present invention is significantly easier to handle when deployed and/or removed from the water since it weighs less than the solid buoy and includes a handle for easier handling.
- The buoy of the present invention is also sufficiently sturdy to withstand the weather conditions and prolonged deployment.
- While the present invention has been illustrated and described with respect to a particular embodiment thereof, it should be appreciated by those of ordinary skill in the art that various modifications to this invention may be made without departing from the spirit and scope of the present invention. For example, the
cavity 20 of thebuoy 10 does not need to be a substantially cylindrical through opening, but rather can have any shape to accommodate ballast and/or water therein. Also, themooring mechanism 32 can have various designs to allow attachment of themooring 52 to thebuoy body 12. Additionally,mooring 52 can be either a chain, as shown inFIG. 1 , or a rope, as shown inFIG. 6 , or any other type of mooring.
