Injection molded hinged knob

A tape measuring device comprising:

• a housing having an aperture;
• a reel assembly disposed in the housing;
• a tape having a first end operably coupled to an end hook and configured to extend from the housing through the aperture and having a second end configured to be wound on the reel assembly;
• and
• a retraction assembly configured to interface with the reel assembly to enable the tape, after extension from the housing to be wound onto the reel assembly,
• wherein the retraction assembly comprises a crank operably coupled to the reel assembly to turn the reel assembly responsive to rotation of the crank,
• wherein the retraction assembly comprises a knob operably coupled to the crank via a knob hinge, the knob hinge being rotatable between a closed position for storage or transport and an open position for operation of the retraction assembly, and
• wherein the knob hinge is configured to be retained in each of the open position and the closed position,
• wherein the knob hinge comprises a base having a longitudinal centerline aligned with a hinge axis about which the knob hinge rotates between the open and closed position,
• wherein the knob hinge comprises hinge bearings extending from opposing ends of base along the hinge axis,
• wherein the knob hinge and the crank each comprise structures forming a locking interface configured to retain the knob hinge in each of the open position and the closed position,
• wherein the crank includes bearing retainers disposed to face each other opposite a receiving orifice formed in the crank,
• wherein the bearing retainers are configured to rotatably receive the hinge bearings therein, and
• wherein the locking interface is disposed outwardly from each of the bearing retainers with respect to the base.
