ABSTRACT:
A molded rubber recreational block locking system, wherein a molded rubber recreational surface block includes an upper surface and a resilient supporting structure below the upper surface. At least one recessed shoulder is located below the upper surface and intersects a marginal edge of the molded rubber recreational surface block. A fastening device interconnects adjacently positioned recessed shoulders in adjacent molded rubber recreational surface blocks for securing same together. Typically, at least one generally vertically directed through hole extends through each recessed shoulder and a flexible fastening device, such as a fastening strap, interconnects the through holes of adjacently positioned recessed shoulders in adjacent molded rubber recreational surface blocks. A cap covers the fastening device and recessed shoulders of adjacently positioned molded rubber recreational surface blocks.
