Abstract
A tape measure including an elongate tape blade is shown. The tape measure includes a relatively short protective polymer film coupled to an end of the tape blade adjacent to the hook end of the tape blade.
Claims20
A tape measure, comprising:
- a housing defining a cavity;
- a reel rotatably mounted in the cavity, the reel configured to rotate around a rotational axis;
- an opening formed in the housing;
- a tape blade wound around the reel, the tape blade having an inner end coupled to the reel and an outer end extending through the opening, the tape blade comprising:
- an inner layer comprising a first surface and a second surface opposite the first surface, wherein the first surface includes a concave curved section, and the second surface includes a convex curved section;
- a first polymer coating layer covering at least a portion of the first surface of the inner layer;
- a second polymer coating layer covering at least a portion of the second surface of the inner layer;
- and
- a protective film coupled via an adhesive to an outer surface of the second polymer coating layer at the outer end of the tape blade, the protective film having a length less than a total length of the tape blade;
- a hook assembly coupled to the outer end of the tape blade;
- and
- a retraction system coupled to the reel and configured to drive reel about the rotational axis such that the tape blade is retracted through the opening and into the cavity;
- wherein a thickness of the first polymer coating layer is between 0.01 mm and 0.03 mm;
- wherein a thickness of the second polymer coating layer is between 0.01 mm and 0.03 mm;
- and
- wherein the adhesive has a thickness between 0.01 mm and 0.05 mm.

A tape measure, comprising:
- a housing:
- a reel rotatably mounted within the housing;
- a tape blade wound around the reel, the tape blade having an inner end coupled to the reel and an outer end extending from the housing, the tape blade comprising:
- a metal inner layer comprising a first surface and a second surface opposite the first surface;
- a first polymer coating layer covering at least a portion of the first surface of the metal inner layer;
- a second polymer coating layer covering at least a portion of the second surface of the metal inner layer;
- an adhesive layer coupled to the metal inner layer;
- and
- a protective film coupled to the adhesive layer, the protective film comprising a PET polymer material, and wherein the protective film has a length that is less than 20% of a total length of the tape blade;
- and
- a hook assembly coupled to the outer end of the tape blade, wherein a portion of the hook assembly overlaps the protective film;
- and
- a retraction system coupled to the reel, wherein the retraction system drives rewinding of the tape blade on to the reel.
