Abstract:
A tool, such as a tape measure, including a spring-based retraction system is shown. The spring-based retraction system includes a motor spring system that drives a tape reel during tape retraction. The output drum of the motor spring system is coupled to the tape reel such that rotation of the reel causes rotation of the output drum. The output drum is located adjacent to the tape reel, and the output drum and tape reel may have a common axis of rotation.

Claim (Index 1):
A tape measure comprising:\n a housing comprising a tape blade opening; a tape reel rotatably mounted within the housing defining an axis of rotation, the tape reel comprising a radially outward facing surface; an elongate tape blade wound around the radially outward facing surface of the tape reel; and a spring-based retraction system comprising:\n a storage drum; \n an output drum coupled to the tape reel and located outside of and adjacent to the tape reel in a direction along the axis of rotation of the tape reel; and \n a spring coupled at a first end to the storage drum and at a second end to the output drum; \n wherein, when the tape blade is extended from the tape blade opening, the spring is unwound from the storage drum and wound around the output drum storing energy within the spring; \n wherein, during tape blade retraction, the spring is unwound from the output drum and wound around the storage drum releasing energy driving winding of the tape blade on to the reel.
