Abstract:
A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.

Claim (Index 11):
The tape measure of  claim 1 , further comprising:\n a shaft; a spiral spring coupled between the tape reel and the shaft such that, when the elongate tape blade is unwound from the tape reel to extend from the housing, the spiral spring stores energy and the spiral spring releases energy driving rewinding of the elongate tape blade on to the tape reel; and a turn reduction mechanism rotatably coupling the spiral spring to the tape reel such that, during extension of the elongate tape blade from the housing, each full rotation of the tape reel is translated into less than a full rotation of the spring.
