Patent ID: 7862248

Claim:
A pen retention bracket for releasably securing a pen tether retracting reel therein, the bracket comprising: a first surface and a second surface, the second surface disposed parallel to and opposite the first surface; a third surface and a fourth surface, the fourth surface disposed parallel to and opposite the third surface, thereby defining a rectangular cavity having four sides comprising the first surface, the second surface, the third surface, and the fourth surface, the rectangular cavity having a top opening and a bottom opening, the top opening disposed opposite the bottom opening; and a first protrusion and a second protrusion disposed upon the first surface, the first protrusion and the second protrusion extending from the first surface toward the second surface, a distance between the first protrusion and the second protrusion greater than a height of the pen tether retracting reel; wherein a depth between the first surface and the second surface is approximately equal to a depth of the pen tether retracting reel; wherein a depth between the second surface and both of the first protrusion and the second protrusion is less than the depth of the pen tether retracting reel; wherein the first surface is responsive to an application of force to the pen tether retracting reel to elastically deform and increase the depth between the second surface and at least one of the first protrusion and the second protrusion, thereby releasing the pen tether retracting reel via either of the top opening and the bottom opening.
