  • Patent number: 6783304
    Abstract: A weather resistant dock walkway comprises a dock walkway substructure in combination with a plurality of elongated planks each with a first and second opposite ends. The planks are rotatable between a horizontal position and a vertical position, and are arranged side-by-side. The first and second opposite ends of each plank are attached to the opposite ends of the substructure. The planks are responsive to contact with a body of water such that the planks rotate from a horizontal position to a vertical position to enable surging water to circulate freely between the vertical planks to prevent surge damage to the weather resistant dock walkway. A ratchet system can be used to reversibly lock the planks in a vertical position.

  • Patent number: 6585454
    Abstract: An anchoring arrangement is provided for anchoring a dock leg to a bottom of a body of water. A base plate has a lumber or timber receiver on its top surface and has three or more anchor legs that are attached to the base plate and that extend downwardly. At least one of the anchor legs preferably has a fluke pivotally attached to it so that when the anchor leg is pushed downwardly into a bottom of a body of water the fluke pivots into contact with the anchor leg. A subsequent attempt to pull the anchor leg upward causes the fluke to pivot into an extended position in which it provides additional resistance to the upward motion of the anchoring leg. Most small docks have legs made of conventional lumber or timbers large enough to provide a buoyant force adequate to support thsi metal anchoring apparatus.

The dock compensator is comprised of constant force power springs, a reel around which sufficient lengths of cable are wound, and a case containing the springs, cables and reel. The dock compensator is attached underneath a floating dock. The cables are withdrawn from the dock compensator and attached to weights placed on the floor of the body of water. The springs maintain a constant pull-force on the cables to hold the dock in place, and the cables automatically dispense or retract to compensate for changes in water level. Thereby, the dock has some leeway in terms of movement in response thereto, but is eventually stabilized by the dock compensator.

  • Patent number: 5281055
    Abstract: The present invention concerns a floating dock which is economical, durable and easy to install and maintain. The dock is comprised of uniform floating docking sections coupled together with rubber male-type anchors which fit into female-type receiving sockets on the docking sections. The two anchors of the couplers are secured together by a tie rod. The docking sections eliminate the need for boat bumpers, wood planking or other additional parts and expenses but allow for the attachment of desired accessories such as spud pipes, gang planks and tie-up cleats. The versatile docking sections can be arranged in an unlimited number of dock designs.

  • Patent number: 5267811
    Abstract: A portable dock consisting of a raised V-Shaped structure, with an essentially rectangularly shaped horizontal base with attached spaced apart angled platforms situated above the base, said dock adapted to reside substantially underwater. The raised V-shaped structure has an open medial channel which enables the platforms to act as cradle members to engage opposite sides of a watercraft, as the watercraft to be docked is maneuvered into the open medial channel bow first. As the watercraft advances from the rear to the front of the dock, along the long axis of the base, the bow rests upon and is elevated by the incline of the platforms. The weight of the watercraft, as it rests upon the platforms, serves to anchor the dock to the bottom of the lake bed, thereby rendering both the watercraft and the dock stationary.The invention may be easily placed into the body of water and removed therefrom by hand, as it is of such a size and weight so as to allow easy manual transport.

  • Patent number: 5156493
    Abstract: A dock kit to permit an owner to assemble or disassemble a dock comprising a dock post bracket for laterally inserting a dock post therein, a reversible cross-latch member for locking a dock post in the dock-post bracket with the reversible cross-latch member operable for engaging a dock-abutment bracket to support an adjacent dock section when the cross-latch member is located in one direction in the dock-post bracket and when reversed is usable as an end support for the dock-post bracket. The brackets provide both corner reinforcement for a dock-deck section as well as permitting a single dock post to support corners of adjacent dock-deck sections. A split foot pad permits adjustment of the depth the dock post extends into the soil. A hanger bracket permits one to support the corner of an adjacent dock-deck section without using an extra dock post.

  • Patent number: 5112159
    Abstract: A Marine Structure for use in a body of water, having a deck positioned above the water's surface, and a vessel landing stage position at the water surface. A stairway having its upper and hinged to the deck, is normally supported with its lower end in contact with the landing stage. An elevating mechanism depending from the deck is operable to lift the stairway's lower end to a position above the water's surface, adjacent to the deck. The stairway is retained in its raised position by a docking facility, and is secured thereby from damage which could otherwise occur due to strong wind and wave action. An alignment coupling carried on the respective stairway and docking facility allows the two members to be firmly, yet resiliently joined to better resist wind or wave forces.
