ABSTRACT:
A tape measure (11) is provided having a first plate (13), a second plate (15), and a spool assembly positioned between the first and second plates. In one embodiment, the first plate includes a central hub (17) and a plurality of upright posts (25), the combination being integrally formed from a single piece of plastic material. In one embodiment, the spool assembly includes a spiral spring (53), a tape (51), a spring-retaining disc (31) having a central hole (35) and an upright intermediate wall (41) with a slot opening (47), an upper disc (33), and a connector (55). In an assembled state, one end of the spiral spring engages the hub, while the other end of the spiral spring engages one end of the connector. The other end of the connector extends through the upright intermediate wall slot opening and engages one end of the tape. The connector second end is held outward of the wall slot in a manner prohibiting its passage back therethrough during use. Further, a braking assembly is provide to allow the tape to be maintained in an extended position. In one embodiment, the braking assembly includes a sliding brake element (87) and a stationary brake base (79) integrally formed with the first plate at a location between two posts. A notch (93) in the brake base engages one end of the sliding brake element to maintain the element in an unlocked state.
