Tape measure with extended standout
View Patent ↗A tape measure comprises a main case having first and second sidewalls and a peripheral wall extending between the sidewalls; a flexible tape blade selectively deployable from the case; the tape blade having a generally curved cross-sectional profile when deployed from the main case and having a generally flat profile when retracted into the main case; a hook attached to a first end of the tape blade so as to be movable a distance along a longitudinal axis of the tape blade; the hook having a first section disposed generally parallel to the longitudinal axis and a second section connected thereto and disposed generally normal to the longitudinal axis, the hook comprising titanium and having a weight factor of not more than about 0.60. The tape blade may advantageously be not more than about 1.10 inch in width and have a standout of at least 9½ feet.
1. A tape measure, comprising:
a main case having first and second sidewalls and a peripheral wall extending between said sidewalls;
a flexible tape blade selectively deployable from said case; said tape blade having a generally curved cross-sectional profile when deployed from said main case and having a generally flat profile when retracted into said main case; said blade comprising a distal end portion, an inner end portion, and an expected buckling region therebetween; said distal end portion being deployed before said expected buckling region and said inner end portion when said blade is deployed from said case;
a hook attached to said distal end portion of said tape blade so as to be movable a distance along a longitudinal axis of said tape blade; said hook comprising a first section disposed generally parallel to said longitudinal axis and a second section connected thereto and disposed generally normal to said longitudinal axis;
a reinforcement distinct from but permanently attached to said blade in said expected buckling region, said distal end portion and said inner end portion being free of said reinforcement;
said expected buckling region including a location where said blade would normally buckle in a standout test absent said reinforcement.
2. The tape measure of claim 1 wherein said reinforcement comprises a metallic plate.
3. The tape measure of claim 1 wherein said reinforcement comprises a longitudinally disposed fiber reinforcement.
4. The tape measure of claim 3 wherein said fiber reinforcement comprises a material selected from the group consisting of carbon and aramid.
5. The tape measure of claim 1 wherein said reinforcement is attached to said blade in said expected buckling region by adhesive.
6. The tape measure of claim 1 wherein said expected buckling region is located between about nine and ten-and-one-half feet from said hook.
7. The tape measure of claim 1 wherein said hook has a weight factor not more than about 0.60.
8. The tape measure of claim 1 wherein said reinforcement is attached to said blade on an upper side thereof.
9. The tape measure of claim 8 :
wherein said expected buckling region is located between about nine and ten-and-one-half feet from said hook;
wherein said hook has a weight factor not more than about 0.60; and
wherein said reinforcement comprises a metallic plate.
10. The tape measure of claim 1 :
wherein said expected buckling region is located between about nine and ten feet from said hook;
wherein said reinforcement comprises a longitudinally disposed fiber reinforcement, said fiber reinforcement comprising a material selected from the group consisting of carbon and aramid; and
wherein said hook has a weight factor not more than about 0.60.
