Top-lock connector for a floating dock
A connector for connecting together two floating dock sections includes a first half having a pair of slotted cylinders and a second half with a pair of cones. A pair of rods connects the first half to the second half. When the two halves are loosely connected together, the connector is inserted into opposing receiver sockets of a pair of opposing floating dock members. A flange located at an upper end of the first half arrests the downward travel of the inserted and loosely connected first and second halves. As the rods are tightened, the pair of cones travel toward the pair of slotted cylinders and cause the slotted cylinders to expand radially outward.
1. A connector for connecting a pair of opposing floating dock members, each floating dock member having a vertically oriented receiver slot, the receiver slot located on a periphery of the floating dock member and extending from a topside of the floating dock member past a midline of the floating dock member, the receiver slot having an axially-extending cylindrical wall portion and an axially-extending planar slot portion disposed at the periphery, the connector comprising:
a upper half and a lower half that when loosely connected one to the other are adapted for topside-down insertion into the receiver slot and top-side removal from the receiver slot, the connector sized to extend from the topside of the floating dock member past the midline of the floating dock member and arranged to move between a loosely connected state and a tightly connected state;
the lower half of the connector including a pair of parallel axially-extending cones connected by an axially-extending planar center spacer,
the upper half of the connector including a pair of parallel axially-extending slotted cylinders each comprising a plurality of axially-extending slots and connected by an axially-extending planar center spacer,
each cone sized for insertion into its respective slotted cylinder, each slotted cylinder sized for insertion into the cylindrical wall portion of a respective floating dock member, and the center spacers of the upper and lower halves being sized for insertion into the planar slot portions of the dock members,
a base diameter of each cone being greater than an inner diameter of its respective slotted cylinder;
a pair of threaded rods, each rod in the pair of rods passing through a respective slotted cylinder in the pair of slotted cylinders and being received by a correspondingly threaded upper portion of a respective cone in the pair of cones, each rod when tightened drawing the respective cone upward toward the respective slotted cylinder, such that the center spacer of the lower half is received within a corresponding slot of each of the slotted cylinders and the cones radially expand the slotted cylinders to clamp against the cylindrical wall portion of each receiver slot, and moving the connector between the loosely connected state and the tightly connected state;
a flange located at an upper end of the upper half and receivable within a shelf portion recessed within the topside of each floating dock member to arrest the downward travel of the upper half when in the loosely connected state and while being inserted into the receiver slots.
