Claim 15:
16. A fall arrest system comprising:
a spike assembly positioned relative to an elevated surface, said spike assembly being moveable between a stowed configuration and a deployed configuration; and
a trigger assembly operatively coupled to said spike assembly, said trigger assembly being moveable between a set configuration and a released configuration, wherein said spike assembly includes a spike member,
wherein said spike member is displaced from the elevated surface when said spike assembly is in the stowed configuration,
wherein said spike member is configured to pierce the elevated surface as said spike assembly moves towards the deployed configuration,
wherein said trigger assembly retains said spike assembly in the stowed configuration when said trigger assembly is in the set configuration,
wherein said trigger assembly allows said spike assembly to move from the stowed configuration to the deployed configuration when said trigger assembly is in the released configuration,
wherein said spike member is oriented at a first angle relative to said mobile cart when said spike assembly is in the deployed configuration and wherein said spike member is oriented at a second angle relative to said mobile cart when said spike assembly is in the stowed configuration,
wherein the first angle is approximately forty-five (45) degrees, and
wherein the second angle is less than forty-five (45) degrees.
