Abstract
Abstract Tool system (10) advantageously provides tool (12), adapter (14) and extension member (16) successively coupled so that groove (34) mates with rib (44) in the assembled position. Groove (34) and rib (44) are engaged so that tool (12) is axially fixed relative to adapter (14) yet is axially rotatable relative thereto. In preferred embodiments adapter body (36) includes a shoulder (42), and adapter (36) and handle member (20) are correspondingly tapered with increasing radius from top to bottom so that the snapping, engaging action of handle member (20) on adapter head (36) is enhanced when the system (10) is assembled.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A tool system comprising: an elongated adaptor presenting a longitudinal axis and including an adaptor head having a body portion presenting a circumferential rib disposed about the exterior thereof; a tool including a functional member and a hollow handle member presenting an inner surface for rotatably receiving said adaptor head therein integrally depending from said functional member, the inner surface including a portion forming a female groove; and elongated extension member presenting a curved portion and having a connection end non-rotatably secured within said adaptor, said inner surface of said handle being configured to receive a portion of said adaptor head including said circumferential rib therein for pivotal movement of said tool about said longitudinal axis, said female groove of said tool releasably, matingly receiving said rib whereby said tool is axially fixed relative to said adaptor, the fit between said handle and said adapter when said rib is received in said groove being sufficiently low in friction to permit relative pivotal movement therebetween.
Claim 2
Dependent Claim
164 words
A tool system comprising: an elongated adaptor presenting a longitudinal axis and including an adaptor head having a body portion presenting a circumferential rib disposed about the exterior thereof; a tool including a functional member and a hollow handle member presenting an inner surface for rotatably receiving said adaptor head therein integrally depending from said functional member, the inner surface including a portion forming a female groove; and elongated extension member presenting a curved portion and having a connection end non-rotatably secured within said adaptor, said inner surface of said handle being configured to receive a portion of said adaptor head including said circumferential rib therein for pivotal movement of said tool about said longitudinal axis, said female groove of said tool releasably, matingly receiving said rib whereby said tool is axially fixed relative to said adaptor, the fit between said handle and said adapter when said rib is received in said groove being sufficiently low in friction to permit relative pivotal movement therebetween.
Claim 3
Dependent Claim
20 words
A tool system as set forth in claim 1, wherein said functional member is oriented transversely to said longitudinal axis.
Claim 4
Dependent Claim
19 words
A tool system as set forth in claim 2 wherein said functional member is releasably mounted to said tool.
Claim 5
Dependent Claim
17 words
A tool system as set forth in claim 3 wherein said functional member is a squeegee blade.
Claim 6
Dependent Claim
58 words
A tool system as set forth in claim 1 wherein said adapter head includes a threaded portion, said inner surface of said hollow handle member being configured to receive said threaded portion therein when said rib is located in said groove with said tool being rotatable above said longitudinal axis when said rib is located in said groove.
