Abstract
The present invention discloses a manual force reduction device for reducing a force required to initiate movement of a load by a separate mechanism. The device can have an energy storage mechanism that has a compressed position and a released position, and the energy storage mechanism can be operable to store a predetermined amount of energy when it is in the compressed position. A latch can be included and be used to hold the energy storage mechanism in the compressed position. At a desired time, a latch release can release the energy storage mechanism from the compressed position such that the predetermined amount of energy is released and transferred to the load.
