Abstract

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

First claim

What is claimed is:

1. A tool including:
a handle assembly including a top portion and a bottom portion;
a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, and a detent near the free end; and
a blade disposed between the top portion and the lock plate, the blade having top and bottom surfaces, an indent in the bottom surface for engaging the detent in a closed position, and a ramp on the bottom surface defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

2. The tool according to claim 1 , wherein the deflectable arm additionally includes an inner edge, an outer edge, an elongate opening near the fixed end and spaced from the inner and outer edges to form a pair of continuous regions of the deflectable arm around the elongate opening extending in a direction from the fixed end towards the free end.

3. The tool according to claim 2 , wherein the elongate opening has an inner edge proximate and parallel to the inner edge of the deflectable arm and an outer edge proximate and parallel to the outer edge of the deflectable arm such that the continuous regions each maintain a substantially constant width in a direction from the inner edge of the deflectable arm to the outer edge of the deflectable arm.

4. The tool according to claim 1 , wherein the lock plate includes a longitudinal axis and a substantially L-shaped cutout having a first portion extending axially and a second portion extending perpendicular to the axis, and wherein the cutout separates the lock plate into a body portion and the deflectable arm.

5. The tool according to claim 4 , wherein the fixed end is integrally formed with the body portion, the free end is spaced from the body portion by the second portion of the cutout, and an inner edge of the deflectable member is spaced from the body portion by the first portion of the cutout.

6. The tool according to claim 4 , wherein the deflectable arm is biased towards the top portion such that the free end is above a plane of the body portion forming an incline.

7. The tool according to claim 1 , wherein the blade includes a loop for a user to grab to move the blade from a closed position to the open position, and the top portion includes a notch extending inwardly from a side of the top portion to expose the deflectable arm and the loop.

8. The tool according to claim 7 , wherein the blade includes a roller cleaner.

9. The tool according to claim 7 , wherein the blade further includes an opening for receiving a pivot, wherein the indent is closer to the loop than the opening.

10. The tool according to claim 1 , wherein the lock plate includes a tool portion at an end.

11. The tool according to claim 1 , wherein the bottom portion has an outer surface and a clip integrally formed with the outer surface.

12. A tool including:
a handle assembly including a top portion and a bottom portion;
a blade disposed between the top and bottom portion; and
a lock plate disposed between the top and bottom portions and having first and second ends and a deflectable arm extending in a longitudinal direction from the first end to the second end, the deflectable arm having:
a free end biased towards the top portion,
a fixed end opposite the free end,
an inner edge,
an outer edge, and
an elongate opening near the fixed end and spaced from the inner and outer edges to form a pair of continuous regions around the elongate opening extending in the longitudinal direction.

13. The tool according to claim 12 , wherein the elongate opening has an inner edge proximate and parallel to the inner edge of the deflectable arm and an outer edge proximate and parallel to the outer edge of the deflectable arm such that the continuous regions each maintain a substantially constant width in a direction from the inner edge of the deflectable arm to the outer edge of the deflectable arm.

14. The tool according to claim 12 , wherein the lock plate includes a substantially L-shaped cutout having a first portion extending in the longitudinal direction and a second portion extending in a direction perpendicular the longitudinal direction, and wherein the cutout separates the lock plate into a body portion and the deflectable arm.

15. The tool according to claim 14 , wherein the fixed end is integrally formed with the body portion, the free end is spaced from the body portion by the second portion of the cutout, and the inner edge is spaced from the body portion by the first portion of the cutout.

16. The tool according to claim 12 , wherein the deflectable arm includes a detent near the free end and the inner edge that extends towards the top portion.

17. The tool according to claim 16 , wherein the blade has a top surface that abuts a bottom surface of the top portion, a bottom surface that abuts a top surface of the lock plate, an indent in the bottom surface for engaging the detent in the closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

18. The tool according to claim 12 , wherein the blade includes a loop for a user to grab to move the blade from the closed position to the open position, and the top portion includes a notch extending inwardly from a side of the top portion to expose the deflectable arm and the loop.

19. A tool including:
a handle assembly including a top portion having first and second ends and a bottom portion having first and second ends;
a blade disposed between the top and bottom portion and having first and second ends and a loop engageable by a user to move the blade from a closed position to an open position; and
a lock plate disposed between the blade and the bottom portion and having first and second ends and a deflectable arm having:
a free end biased towards the top portion,
a fixed end opposite the free end,
an inner edge, an outer edge, and
an elongate opening near the fixed end and spaced from the inner and outer edges to form a pair of continuous regions around the elongate opening extending in the longitudinal direction,

wherein the lock plate includes a tool portion at the first end, and
wherein the blade is rotatable about the first end between the closed positioned where the second end of the blade is held within the handle assembly by the deflectable arm, and the open position where the second end of the blade is outside the top and bottom portions and the first end of the blade is engaged by the free end of the deflectable arm to hold the blade in the open position.

20. The tool according to claim 19 , wherein the top portion includes a notch extending inwardly from a side of the top portion to expose the deflectable arm and the loop of the blade.
