Abstract:
In combination for use in a pogo stick, a housing, a handle disposed at the top of the housing and defining a balanced relationship with the housing, a foot rest disposed at an intermediate position on the housing and defining a balanced relationship with the housing, an actuator extending into the housing in an aligned relationship with the housing for movement in the housing in accordance with the actuation of the pogo stick onto the ground and the subsequent release of the pogo stick from the ground, a casing disposed between the housing and the handle in an aligned relationship with the housing, a spring disposed in the housing and operatively coupled to the actuator to become constrained upon the actuation of the pogo stick onto the ground and to become released of the constraint upon the release of the pogo stick from the ground, a resilient member disposed in the casing in a first position and responsive to each actuation of the actuator onto the ground to become moved to a second position and responsive to each release of the actuator from the ground to become returned to the first position, a stationary contact disposed in the casing, a switch disposed in the casing and including the resilient member and the stationary contact and having first and second states of operation and operable in the first state with the resilient member in the first position and operable in the second state with the resilient member in the second position, a counter disposed in the casing for counting the number of operations of the resilient member in the second state, and a member disposed in the casing for providing a sensory indication when the count in the counter has reached a particular value.
