Abstract
A tape measure including a reinforced or coated tape measure blade is provided. The coating is thicker than the metal inner layer of the tape blade. The coating provides a reinforced tape blade such that elongate tape blade may have a pinch load threshold of greater than 50 lbs. and/or a pinch height at break of less than 1.5 mm. A hook assembly may also provide for reduced stress at the end of the tape blade.
Claims20
A tape measure comprising:
- a housing:
- a reel rotatably mounted within the housing;
- an elongate blade wound around the reel, the elongate blade comprising:
- an elongate metal core having an upper surface, a lower surface and a first thickness, T1, measured between the upper surface and the lower surface;
- an upper polymer coating coupled to and covering the upper surface of the elongate metal core, the upper polymer coating having a second thickness, T2, and an upper surface defining the uppermost surface of the elongate blade;
- a lower polymer coating coupled to and covering the lower surface of the elongate metal core, the lower polymer coating having a third thickness, T3, and a lower surface defining the lowermost surface of the elongate blade;
- and
- a series of measurement markings;
- wherein T2+T3≥T1;
- and
- a retraction mechanism coupled to the reel and configured to drive rewinding of the elongate blade on to the reel.
