Abstract:
An inverting spring assembly comprising:a housing having a first support member, a second support member spaced opposite said first support member, a third support member, and a fourth support member spaced opposite said third support member, said first support member and said second support member being spaced at a distance Y from one another; a resilient strip having a first end defining a first fixed pivot, a second end defining a second fixed pivot, and a length X wherein said resilient strip is flexible and unrestrained between said first and second pivots and wherein the distance X is greater than the distance Y, said resilient strip supported between said first support member and said second support member with said first end of said resilient strip supported by said first support member and said second end of said resilient strip supported by said second support member; and an actuator interconnected with said housing for applying force to said resilient strip in both a first direction and a second direction thereby allowing said resilient strip to be repetitively moved between a first position and a second position.
