  • Patent number: 4460823
    Abstract: A pedometer for indicating distance traveled by a user in walking or running. A mechanical digital counter is provided and driven by a gear train from a ratchet wheel. A pivoted pendulum is maintained in an at-rest position by a first biasing spring which is suitable for use during walking. During running when more kinetic energy is developed in the pendulum, a second biasing spring may be selectively engaged with the first biasing spring to increase the tension thereof for absorbing the additional energy without damage to the apparatus. A movable stop for the pendulum is provided having an external adjustment knob to set the pendulum travel in accordance with the length of stride of the user. The user may change the length of stride and the walk/run mode without resetting of the digital distance indicator.
