Handles

Claim 2

A paint applicator having a guide formation with clamping edges and an intermediate flexible base and releasably receiving a handle arrangement in loose slidable engagement therewith, the said handle arrangement including spaced lateral guide-engaging edges for co-operation with said clamping edges of the guide formation, a handle extending outwardly from a plane defined by the said lateral edges, and locking means pivotally mounted on the handle for pivotal movement about an axis parallel to said plane and selectively pivotally adjustable between first and second positions thereon respectively representing inoperative and operative conditions of the locking means, the said locking means including a cam member having a part movable outwardly of the handle on pivotal adjustment between said first and second positions for co-operation with the flexible base of the guide formation to flex it downwardly to urge the clamping edges toward each other end into frictional clamping engagement with the guide engaging edges, the said second position of the locking means corresponding to an over-center position of the cam member.

Claim 3

A handle arrangement in combination with a lipped channel comprising a base plate having spaced opposed lateral edges for engagement with respective opposite longitudinal sides of the channel, a handle member extending from said edges and outwardly of the plane defined thereby and a locking means arranged in association with the handle member and selectively adjustable about a pivot axis parallel to the said opposed lateral edges between a first, or datum, position wherein a part thereof is relatively retracted in relation to the general plane of the edges and a second position wherein said part is displaced outwardly from such plane, the said locking means comprising an edge cam having a periphery for engagement with the lipped channel intermediate the lateral limits thereof when the locking means is in the said second position, which second position represents an over-center position of the cam.

Claim 4

A handle arrangement in combination with a lipped channel comprising a base plate having spaced opposed lateral edges for engagement with respective opposite longitudinal sides of the channel, a handle member extending from said edges and outwardly of the plane defined thereby and a locking means arranged in association with the handle member and selectively adjustable about a pivot axis parallel to the said opposed lateral edges between a first, or datum, position wherein a part thereof is relatively retracted in relation to the general plane of the edges and a second position wherein said part is displaced outwardly from such plane, the said locking means comprising an edge cam having a periphery for engagement with the lipped channel intermediate the lateral limits thereof when the locking means is in the said second position, which second position represents an over-center position of the cam.

Claim 5

A handle arrangement as claimed in claim 2, wherein the locking means is mounted within the handle and includes an operating lever extending from said handle, the said operating lever being adapted, upon adjustment, to shift the said cam between said first and second positions.

Claim 6

A handle arrangement as claimed in claim 2, wherein the cam comprises an eccentrically mounted disc-like element and the locking means further includes an operating lever secured to the cam and adapted upon adjustment between the first and second positions to move the cam through an over-center position.

Claim 7

A handle arrangement as claimed in claim 4, wherein the operating lever is formed integrally with the cam.

Claim 8

A handle arrangement as claimed in claim 4, wherein the cam has angularly spaced displacement and clearance portions at respective distances from the pivot axis of the cam, the displacement portion being spaced from the said pivot axis by a greater distance than the clearance portion but by a lesser distance than a node provided between such portions.

Claim 9

A handle as claimed in claim 2 in combination with a paint pad, the said paint pad including a body part and a lipped channel formation on such body part, the handle being engaged with such channel formation and retained therein by cooperation between the lateral guide-engaging edges of the handle and the lips to the channel formation, the edge cam periphery being engageable with the bottom of the channel and adapted, in the second displaced position of the locking means, to urge the lips of the channel into frictional engagement with the said guide-engaging edges of the handle.

Claim 10

A handle structure with an applicator support having a pair of spaced upstanding clamping ribs and an intermediate base adapted to be flexed downwardly for drawing the ribs inwardly for clamping the handle structure to the support, the handle structure having a base with a pair of spaced flanges, a handle extending upwardly from a plane of the handle base and locking means pivotally mounted on the handle about an axis generally parallel to said plane and selectively pivotally adjustable between a release position and a locking position, the handle base being adapted, with the locking means in its release position, for being freely detached from and freely attached to the applicator support with its flanges between and in loose interlocking relationship with the clamping ribs of the applicator support, the pivotal locking means having a pivotal cam with a cam part movable downwardly to a pivotal over-center position on pivotal adjustment of the locking means from its release position to its locking position and thereby operable, with the handle structure attached to the applicator support, for engaging the intermediate base of the applicator support and flexing it downwardly for drawing the opposed clamping ribs toward each other and inwardly into clamping engagement with the flanges of the handle base for clamping the handle structure to the applicator support.

Claim 11

A handle structure with an applicator support having a pair of spaced upstanding clamping ribs and an intermediate base adapted to be flexed downwardly for drawing the ribs inwardly for clamping the handle structure to the support, the handle structure having a base with a pair of spaced flanges, a handle extending upwardly from a plane of the handle base and locking means pivotally mounted on the handle about an axis generally parallel to said plane and selectively pivotally adjustable between a release position and a locking position, the handle base being adapted, with the locking means in its release position, for being freely detached from and freely attached to the applicator support with its flanges between and in loose interlocking relationship with the clamping ribs of the applicator support, the pivotal locking means having a pivotal cam with a cam part movable downwardly to a pivotal over-center position on pivotal adjustment of the locking means from its release position to its locking position and thereby operable, with the handle structure attached to the applicator support, for engaging the intermediate base of the applicator support and flexing it downwardly for drawing the opposed clamping ribs toward each other and inwardly into clamping engagement with the flanges of the handle base for clamping the handle structure to the applicator support.

Claim 12

A handle structure according to claim 8 wherein the handle is hollow, wherein the cam is pivotally mounted within the hollow handle and wherein the locking means comprises an operating lever extending generally radially outwardly from the cam and manually operable for pivotally adjusting the locking means between its said release and locking positions.
