Patent number: 7395608Abstract: A tape measure includes a reel, a tape that is wound on the reel and that can be reeled out, and a hook attached to a free end of the tape. The tape includes a concave-convex shape when it is reeled out. The concave-convex shape includes a height and a width and provides rigidity for the standout length. The tape includes a flat shape when it is wound on the reel. The flat shape includes a flattened width. The maximum standout length is not larger than 100 times of the flattened width or the flatness is not larger than one fourth of the flattened width. Thus, the tape can easily be wound and flattened on the reel and will not be deformed because of change in stress when it is retroflexed or wound.Type: GrantFiled: July 13, 2006Date of Patent: July 8, 2008Inventor: Huei-Yen Liao

Patent number: 7107698Abstract: A strengthened blade tape measure includes a tape casing, a retraction unit, and a ruler blade, having an inner end attached to the retraction unit and an outer end stopped at a guiding opening of the tape casing, adapted to slidably fold between a storage position and a measuring position. In which, at the storage position, the ruler blade is retracted to receive in the tape casing in a coil flattened configuration manner via the retraction unit, and at the measuring portion, the outer end of the ruler blade is slidably pulled to extend the ruler blade in a concave-convex configuration out of the tape casing through the guider opening, wherein the ruler blade is capable of standing out from the tape casing with a measuring length at least 10 feet in a self-sustaining manner so as to prevent the ruler blade from buckling by its own weight.Type: GrantFiled: December 16, 2005Date of Patent: September 19, 2006Inventor: Huei-Yen Liao
