Tool including adjustable handle
First Claim
1. An adjustable tool comprising:
- a tool head configured for doing at least one particular task;
a handle; and
an internally-positioned adjustment mechanism adjustably connecting the tool head to the handle, the adjustment mechanism being configured to support selective angular adjustment of the tool head relative to the handle between at least two different use positions and to hold the tool head in a selected one of said two different use positions, the adjustment mechanism including overlapping flanges and inter-engaging teeth adapted to releasably hold a selected one of the use positions, and including a cover shielding the teeth from dirt but that leaves exposed a portion of the overlapping flanges so that the tool head can be adjusted without distorting the cover.

Abstract
A tool includes different tool heads, and an angularly adjustable handle. The angular adjustability allows better ergonomic body posture during use, thus reducing stress and injury, and also allows multiple functions for each tool. The handle comfortably receives a user'"'"'s hand, with the user'"'"'s thumb or forefinger located at a release button. The release button is spring-biased and includes teeth that inter-engage with teeth on the tool head to latchingly hold a selected angular position. A resilient cover encases the handle and the release button, preventing dirt from entering the button area to prevent jamming. The covering slips onto the handle and includes an annular lip that stretches over an end surface to retain the covering on the handle. The cultivator includes tines that, by adjusting an angle of the handle, extend in a direction parallel the handle but offset therefrom, or that extend at an angle to the handle.

16. An adjustable tool comprising:
-
a tool head configured for doing at least one particular task; a handle; an internally-positioned adjustment mechanism adjustably connecting the tool head to the handle, the adjustment mechanism being configured to support selective angular adjustment of the tool head relative to the handle between at least two different use positions and to hold the tool head in a selected one of said two different use positions; wherein the handle includes an outer surface defining a geometric shape; wherein the internal adjustment mechanism includes a latch member located within the geometric shape; and a cover that covers the latch member to prevent dirt and debris from entering an area around the latch member, wherein the cover encloses and covers a majority of the handle.

20. An adjustable tool comprising:
-
a tool head; a handle adjustably connected to the tool head, the handle including a recess adapted to ergonomically receive and support a user'"'"'s thumb and fingers so that pressure can be readily communicated through the handle to the tool head while using the tool; and a release button movable between a released position and a latched position for fixing the tool head to the handle in a selected adjusted position, the release button being located near the recess where the release button is easily operated by the user to adjust the tool head, the release button including first teeth with angled outer edges that engage mating teeth with angled surfaces on the tool head, the angled outer edges and angled surfaces reducing a distance of movement of the button in order to engage or disengage the first teeth. - View Dependent Claims (21, 22, 23, 24, 25)

27. An adjustable tool comprising:
-
a tool head configured for doing at least one particular task; a handle; and an adjustment mechanism adjustably connecting the tool head to the handle, the adjustment mechanism including overlapping flanges on the tool head and the handle, and a pivot pin connecting the overlapping flanges for selective angular adjustment of the tool head relative to the handle between at least two different use positions; and a cover that closely engages an outer surface of the overlapping flanges to prevent dirt and debris from entering an area around the adjustment mechanism, but that leaves at least a part of one of the overlapping flanges exposed so that the tool head can be angularly adjusted without the tool head distorting the cover and without allowing dirt to enter the adjustment mechanism. - View Dependent Claims (28)

29. An adjustable too comprising:
-
a head; a handle connected and adjustable to the head for adjustment around a pivot axis; and a button mounted on the handle adjacent the pivot axis but spaced therefrom and configured to directly release and engage the head allowing adjustment and securing of the head to the handle in at least two different positions; and a cover covering and protecting the button and covering ends of the head and handle at the pivot axis.

30. An adjustable tool comprising:
-
a head; a handle connected and adjustable to the head for adjustment around a pivot axis; and a button mounted on the handle adjacent the pivot axis but spaced therefrom and configured to directly release and engage the head allowing adjustment and securing of the head to the handle in at least two different positions; and
wherein the button and head include mating teeth that releasably engage, the teeth having angled leading edges that engage at an angle thus reducing required movement of the button for disengagement and that provide a wide area of contact even when only partially engaged. - View Dependent Claims (31)
