Modular dock system

Abstract

A floating dock module has a hollow body, preferably hexagonal prismatic, with hexagonal top and bottom walls with side walls and bolt access wells in the top wall with bolt holes extending laterally between each bolt access well and an adjacent side wall for interconnecting dock modules together into various shapes. The resulting dock assembly is flexible and able to conform with wave action. Mating protrusions and recesses in side walls together with bolts secure the high-density roto-moulded polyethylene plastic modules together. Preferably the side walls have a chamfered top and bottom edge to enhance the flexibility of the connection. The top wall includes drainage grooves, the side walls of which form vertical reinforcing ribs. An upwardly extending peripheral wall enables placement of mats, foam, carpet, wood, gravel or sand in the top surface. The bottom wall includes downwardly open float cavities and the top wall includes accessory support holes for railing posts or parasols.

I claim:  
     
         1 . A buoyant module for use in a dock or deck structure, comprising: 
 a hollow body with top, bottom and a plurality of side walls, the top and bottom walls having a non-rectangular polygonal shape.    
     
     
         2 . A buoyant module according to  claim 1  wherein the non-rectangular shape is a hexagon.  
     
     
         3 . A buoyant module according to  claim 1  including a plurality of bolt access wells in the top wall with bolt holes extending laterally between each bolt access well and an adjacent side wall.  
     
     
         4 . A buoyant module according to  claim 1  including one of mating protrusions and recesses in side walls with bolt holes.  
     
     
         5 . A buoyant module according to  claim 1  wherein the side walls have a chamfered top and bottom edge.  
     
     
         6 . A buoyant module according to  claim 1  wherein the top wall includes drainage grooves.  
     
     
         7 . A buoyant module according to  claim 1  wherein the top wall includes vertical reinforcing ribs.  
     
     
         8 . A buoyant module according to  claim 1  wherein the top wall has an upwardly extending peripheral wall.  
     
     
         9 . A buoyant module according to  claim 1  wherein the bottom wall includes downwardly open float cavities.  
     
     
         10 . A buoyant module according to  claim 1  wherein the top wall includes accessory support holes.  
     
     
         11 . A buoyant module according to  claim 10  including accessories mounted to the accessory support holes selected from the group consisting of: posts; roofing structures; walls; slides; kiosks; parasols; chairs; hammocks; and playground equipment.
