Measuring tape with end hook having a high friction surface treatment
A measuring tape device may include a housing having an aperture, a reel assembly, a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly, and an end hook disposed at the first end of the blade. The end hook may have a front face that faces away from the aperture and a rear face that faces toward the aperture. A high friction surface including grains may be disposed over at least a portion of a surface of the rear face.
1. A measuring tape device comprising:
a housing having an aperture;
a reel assembly;
a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly; and
an end hook disposed at the first end of the blade, the end hook having a front face that faces away from the aperture and a rear face that faces toward the aperture,
wherein a width of the end hook is greater than a width of the blade such that portions of the end hook extend outside the width of the blade to provide an expanded surface area for engagement of at least the rear face with a measurement anchor surface, and
wherein a high friction surface comprising grains is disposed on the portions of the end hook that extend outside the width of the blade.
2. The device of claim 1 , wherein the high friction surface is disposed of substantially all of the surface of the rear face.
3. The device of claim 1 , wherein the high friction surface is disposed on the rear face such that edges of the high friction surface are spaced apart from corresponding edges of the rear face.
4. The device of claim 3 , wherein bottom and side edges of the high friction surface and corresponding bottom and side edges of the rear face are substantially equidistantly spaced apart.
5. The device of claim 3 , wherein bottom edges of the high friction surface are spaced apart from corresponding bottom edges of the rear face by a different amount than side edges of the high friction surface are spaced apart from corresponding side edges of the rear face.
6. The device of claim 1 , wherein a surface area of the high friction surface is greater than 1/2 a surface area of the rear face.
7. The device of claim 1 , wherein at least a bottom edge of the high friction surface is coextensive with a bottom edge of the rear face.
8. The device of claim 1 , wherein the grains have substantially uniform or different sizes.
9. The device of claim 1 , wherein the grains are embedded in a base material disposed on the rear face.
10. The device of claim 9 , wherein the base material is an adhesive.
11. The device of claim 1 , wherein the grains are embedded in a base material disposed on the rear face, and
wherein the grains are covered with a resin coating.
12. The device of claim 1 , wherein the high friction surface is disposed on both the front face and the rear face.
13. The device of claim 1 , wherein the end hook comprises a first angled corner that extends outside the width of the blade on a first side of the blade and a second angled corner that extends outside the width of the blade on a second side of the blade, and
wherein the high friction surface is disposed on the first and second angled corners.
14. The device of claim 1 , wherein a bottom edge of the end hook is nonlinear such that a first fraction of the bottom edge lies on a first plane and a second fraction of the bottom edge lies outside the first plane.
15. A measuring tape device comprising:
a housing having an aperture;
a reel assembly;
a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly; and
an end hook disposed at the first end of the blade, the end hook having a front face that faces away from the aperture and a rear face that faces toward the aperture,
wherein a width of the end hook is greater than a width of the blade such that portions of the end hook extend outside the width of the blade to provide an expanded surface area for engagement of at least the rear face with a measurement anchor surface,
wherein a high friction surface comprising grains is disposed on the portions of the end hook that extend outside the width of the blade, and
wherein the grains comprise resin or plastic grains that are compressible.
16. An end hook for a measuring tape device, the end hook comprising:
a front face that faces away from an aperture through which a blade of the measuring tape device is extendible;
a rear face that faces toward the aperture; and
a high friction surface comprising grains,
wherein a width of the end hook is greater than a width of the blade such that portions of the end hook extend outside the width of the blade to provide an expanded surface area for engagement of at least the rear face with a measurement anchor surface, and
wherein the high friction surface is disposed on the portions of the end hook that extend outside the width of the blade.
17. The end hook of claim 16 , wherein the high friction surface is disposed on substantially all of the surface of the rear face, or
wherein the high friction surface is disposed on the rear face such that edges of the high friction surface are spaced apart from corresponding edges of the rear face.
18. The end hook of claim 17 , wherein bottom and side edges of the high friction surface and corresponding bottom and side edges of the rear face are substantially equidistantly spaced apart, or
wherein bottom edges of the high friction surface are spaced apart from corresponding bottom edges of the rear face by a different amount that side edges of the high friction surface are spaced apart from corresponding side edges of the rear face.
19. The end hook of claim 16 , wherein the grains have substantially uniform or different sizes.
20. The end hook of claim 16 , wherein the grains are embedded in a base material disposed on the rear face,
wherein the base material is an adhesive, and
wherein the grains are covered with a resin coating.
