  • Patent number: 6253699
    Abstract: A watercraft beaching device (10) includes one or more collapsible upright supports (11) and (12) which hold a pair cushioned hull engagement surfaces (13) in spaced apart relationship. Advantageously, hull engagement surfaces (13) are elongated to engage more than a single point or area along on side of the hull of watercraft (1) to prevent watercraft (1) from pivoting about the mooring point on the shoreline. Additionally, supports (11) and (12) are configured to hold hull engagement surfaces (13) a sufficient distance above the shoreline to insure that the hull does not come into contact with the aforementioned abrasive agents or shoreline.

  • Patent number: 6226826
    Abstract: Bumpers and assemblies for swimming pool cleaners are disclosed. Such assemblies may include contoured frames to which flexible fins are attached to facilitate deflection of cleaners when obstacles are encountered. Side wings connecting the frame to the body of a cleaner may additionally be employed as part of the assemblies, as may a weight moveable about two axes. In use, the side wings both promote cleaner deflection and reduce body wear that otherwise would occur. The non-stationary weight permits continuous rebalancing of the cleaner depending on its location and orientation within a pool. An optional lower bumper facilitates operation of the cleaner by reducing the likelihood of its becoming trapped against objects such as steps located within swimming pools.

  • Patent number: 6095074
    Abstract: A bumper for a boat dock is provided which is durable, resilient and visible at night. The bumper is constructed of an expanded polymer such as polyethylene or polypropylene. The bumper is preferably made of translucent polyethylene foam with a density of between 2 and 4 pounds per cubic foot. When polyethylene foam is subjected to impact, it absorbs the force of the impact and returns to its original shape. The present invention includes a light for illumination of the bumper itself or illumination of an area immediately adjacent the bumper. A slot in the bumper is provided for accepting the illumination source. If the bumper is translucent, as with white polyethylene foam, the illumination source may be inserted into the back of the bumper such that light is emitted through the front of the bumper. If the bumper is opaque, the illumination source may be inserted into a slot in the bottom of the bumper so that the light is emitted from the bottom of the bumper.

  • Patent number: 6053664
    Abstract: The impact absorption system uniquely features arrangement of composite structures which include fiber-reinforced high strain-to-failure viscoelastic matrix material. According to many embodiments, a gravitationally or buoyantly suspended hollow fiber-reinforced urethane reaction bumper is closely and anteriorly situated with respect to fiber-reinforced urethane tension tubes which are secured at the ends and disposed in an approximately vertical plane. In operation, an incoming marine vessel impacts the bumper which in turn impacts the tubes. The invention takes advantage of the great deformability, high energy absorbency and other beneficial properties of fiber-reinforced high strain-to-failure viscoelastic matrix material. Moreover, applicability/adaptability of individual bumper systems to varieties of marine vessels is made possible through analysis and arrangement/rearrangement/exchange/interchange of structural components.

  • Patent number: 5762016
    Abstract: The invention relates to a dock pole bumper assembly for securing a boat to mooring piling. The assembly has a stationary portion which is secured to the piling and forms a track along which the movable portion glides. A movable portion has a rigid part and a flexible deformable part. The rigid part is provided with a guide channel for engaging the stationary portion during use of the bumper assembly. The resilient deformable portion has an impact-receiving contact surface and non-contacting opposing side walls. Mooring cleats are mounted on the side walls of the rigid member to allow a mooring line of a boat to be secured thereto. An insert of a friction-resistant material is fitted in the guide channel to facilitate movement of the movable portion along the stationary track.

  • Patent number: 5740752
    Abstract: An apparatus for docking a smaller vessel, such as a dinghy, to a substantially horizonal platform or swimstep of a larger vessel, such as a boat. The docking apparatus comprises a pair of mounting brackets attached at spaced locations to the edge of the swimstep. A substantially vertical bumper attached to each mounting bracket extends vertically above and below the swimstep. An adjustment bracket connected between each bumper and mounting bracket permits vertical, horizontal and rotational adjustment of the bumper with respect to the swimstep. For soft dinghies, a line connected to the dinghy and the bumper docks the two together. For hard dinghies, the bumper includes a cushion interposed between the bumper and the hard dinghy.

  • Patent number: 5738033
    Abstract: A bumper and sling arrangement assists a user to dock his or her boat to a dock or the like by allowing the user to set-up the sling in slack condition between moorings on the boat and dock, and then allowing the user to tighten the slackness out of the sling until the boat is pulled into the dock. The bumper is suspended from the sling in between the boat and dock. As the sling is tightened, the bumper is compressed between the boat and dock in order to constrain relative movement between the boat and dock to practically eliminate such relative movement, as well as, simultaneously, to cushion what relative movement that cannot be eliminated.

  • Patent number: 5732645
    Abstract: A marine fender assembly includes a slip sheet for contacting a dock or other second object when a boat is moored. A cushion sheet is connected to the slip sheet, to make a shock absorbing subassembly for absorbing shock of lateral movement of the boat relative to the second object. The cushion sheet may be disposed between the slip sheet and the boat hull. In some embodiments, the slip sheet comprises two layers and a space between the two layers, and the cushion sheet is contained between the two layers, within the slip sheet. A fastener subassembly is secured to the shock absorbing subassembly, typically at the top of the shock absorbing subassembly so that the shock absorbing subassembly may be suspended downwardly along a portion of the boat hull. In some embodiments, attachment of the cushion sheet to the slip sheet is limited to loci adjacent the top of the cushion sheet, whereby sliding movement between the boat and the e.g.

  • Patent number: 5727493
    Abstract: A boat bumper includes an elongated pipe encased in an injection molded material and having a pair of elongated spaced apart pads affixed to a rearward side of the body. Each pad has a generally V-shaped notch formed therein for receiving the bow edge of a boat. A bracket has a head portion extending around the pipe and is located between the two pads, the bracket having a pair of legs projecting rearwardly outwardly through the casing, to receive the eye on the bow of a boat therebetween. A ring is mounted on the bracket and projects diametric to the legs through the casing and forwardly from the body. The casing is formed of a fluorescent colored injection molded material, and the pads are formed of a resilient compressible material to cushion dynamic impacts thereon.

  • Patent number: 5671692
    Abstract: A boat fender is particularly constructed to provide protection where needed on low freeboard boats with a minimum of rolling. The fender includes a substantially cylindrical body portion having first and second ends and an axis of elongation, and an ear portion integral with the body portion at its first end and making an angle of about 45.degree.-100.degree. (e.g. 90.degree.) with respect to the axis of elongation. Both the body portion and the ear portion are of resilient material, such as resilient plastic, and are typically hollow. An opening is provided in the ear portion large enough to receive a line therein for tying the fender to a cleat or support on a boat or dock. The contour between the ear portion and the body portion roughly conforms to the gunwale of a low freeboard boat. The fender may be attached to a boat, or it may be attached to a dock, so as to protect the boat from impacting the dock.
