Patent ID: 7024790

Claim:
A tape measure having a double-axis reel assembly comprising: a primary axis; a primary spool and a first gear turnable together about the primary axis; a flexible measuring tape blade wound upon the primary spool and normally in a fully retracted position on the primary spool; the secondary axis; a secondary spool and a second gear turnable together about the secondary axis; the secondary spool having a self-restoring spring wound around it and contained within the spool so as to wind and unwind about the secondary axis as the second gear turns; and an endless flexible member connecting the first gear and the second gear, whereby extension of the tape blade from its retracted position causes turning of the primary spool which in turn causes turning of the secondary spool to place the spring of the secondary spool in a spring-wound condition which spring will cause retraction of the tape blade upon release of the tape blade from an extended position.
