Quick connect and adjustment hand implement system
First Claim
1. A quick adjustment mechanism for use between a handle which has a first longitudinal axis and an implement which defines a planar surface having a second longitudinal axis and a first lateral axis, said second longitudinal axis extending in a same general direction as said first longitudinal axis, said adjustment mechanism used for altering a handle-to-implement angle easily and quickly, the handle-to-implement angle being altered being the angle defined between said first longitudinal axis of said handle and said second longitudinal axis of said planar surface, said mechanism comprising:
- a) a first element secured to a handle;
b) a second element secured to an implement, one of said first and second elements comprising a toothed member, said toothed member comprising at least one spline wherein said spline includes a first base diameter from which said teeth extend, a non-toothed cylindrical portion adjacent to a row of teeth on said spline, said non-toothed cylindrical portion having a second base diameter, said second base diameter equaling said first base diameter;
c) fixation means associated with the other of said first element and said second element engaging said toothed member to prevent relative angular movement between said first element and said second element;
d) a mechanism to permit said fixation means to be disengaged from said toothed elementwhereby said first element and said second element may be angularly moved to adjust the handle-to-implement angle.

Abstract
A hand tool is provided with a mechanism which permits the handle of a hand tool to be adjusted through a wide array of angles relative to the implement to which it is attached to accommodate different sized users and uses of the tool. Further, a quick connect apparatus permits any of a plurality of hand tools to be connected to a single handle.

5. A quick-connect apparatus for securing any of a plurality of at least three implements to a handle, said quick-connect apparatus comprising:
-
a) first connection means affixed to the handle; b) second connection means affixed to each of the at least three implements, each second connection means being identical in configuration; c) a securement bolt for sandwiching one of said first and second connection means to retain the implement on the handle. - View Dependent Claims (6, 7)

8. A hand tool featuring both a quick-connect apparatus and a quick-adjust mechanism, said hand tool comprising:
-
a) a handle; b) a first element secured to said handle; c) a plurality of at least three implements capable of being attached to said handle; d) a series of second elements, one each of said series being secured to each of said implements including means to releasably attach each of said second elements to said first element; e) said first element having a first member which is engages and is adjustably positionable relative to a second member of each of said second elements permitting a user to vary an handle-to-implement angle as desired.
