  • Patent number: 4543903
    Abstract: Disclosed is a dock connector for connecting two adjacent floating docks. The dock connectors are designed to accommodate substantial lateral, vertical and end-to-end relative motion between the docks. The dock connector includes mounting plates which are securely fastened to each dock segment and a spring which spans between and connects the two mounting plates. Spring connection means are provided to securely attach the ends of the spring to the mounting plates. Deflection limiters attached to the mounting plates help to support the spring and to prevent it from becoming sprung by over-deflection.
