952,473 Int. Cl. A46b 17/08, 17/00 US. Cl. -248 10 Claims ABSTRACT OF DISCLOSURE This invention relates to splash shields for rollers, and is particularly directed to an adjustabl splash shield adapted to provide quick and easy detachment from a standard paint roller for easy cleaning and adjustment.

The provision of splash guards for use with paint rollers is well known. While adjustable guards have previously been provided, these have been characterized by positive locking means providing specific guard positions in relation to the handle vwhichare selectediprior to use of the roller, and which have not been infinitely variable over the range of adjustment. These prior paint shields are also characterized by complexity of structure preventing ready disassembly for purpose of'cleaningand storage.

It is therefore an object of the present invention to provide a readily assembled and disassembled 'splash v guard for use with a roller such as a paint roller having varying arm shapes.

Another object-of the present invention is-to provide a splash guard infinitely variable over a range of adjustment.

A further object of the present invention is to provide a splash guard adjustable by light contact of the guard against the working surface such as the surface being painted, during operation of the roller to which the guard is attached.

A still further object is the provision of an improved splash shield to retain paint splashings and reduce spillage from the shield.

What is provided is an adjustable splash shield, for use with a roller applicator having a handle attachment portion extending therefrom, which comprises a resilient shield attachment means; an adaptor for locking engagement with said resilient shield means and for detachably clipping to said handle attachment portion in predetermined adjustable relation with said roller supporting spindle; mounting plate means secured to said attachment means; arcuate shield support means slidably mounted on said mounting plate means for arcuately positioning about said roller spindle; shield restraint means mounted on said mounting plate to provide restraining forces between said shield support means and said mounting plate means; a subtantially arcuate shield member for providing a shielding surface extending substantially parallel with an arcuate portion of the applicator roller, and movable about the main axis thereof whereby said shield member may be readily positioned about said main roller axis relative to said handle attachment; and locking means to lockingly secure said shield member to said arcuate shield support means.

Other objects and advantages will appear as the description proceeds with reference to the following drawings, in which:

FIGURE 1 is a diagrammatic view of a paint roller having shield attachment means according to the present invention mounted thereon;

FIGURE 2 is a perspective view of the shield assembly;

FIGURE 3 is a diagrammatic view of the paint roller and shield illustrating a further embodiment of the shield attachment means;

FIGURE 4 is a perspective view partly cut away, of the roller shield illustrating the locking mechanism; and

FIGURE 5 is a sectional view along line 55 of FIG- URE 4 illustrating the detail of the shield lip and locking means.

Referring to FIGURE 1 there is shown a roller assembly 10 having a spindle 12 with an arm 14 extending therefrom, a bight portion 16 connecting the arm with a handle shank 18, the roller applicator 17 being mounted upon the spindle 12. This figure illustrates the mounting of the splash shield attachment means 22 to the

handle portions

14, 16 and 18 of the roller assembly 10.

Referring to FIGURE 2, the splash shield 21 includes shield attachment means 22 on which a shield support means 34 is slidably mounted. A shield 50 is detachably mounted on the support means 34, and shield restraint means 42 are interposed between the shield support means 34 and the shield attachment means 22, to provide restraining force to limit the movement of the shield relative to the attachment means 22.

The shield attachment means 22 includes a pair of

channel members

24, 26 inclined at right angles to each other, being formed of resilient material adapted to engage as a clip-on with the

arm portions

14, 16 and 18 of the roller assembly 10. The attachment means 22 also .includes mounting plate means 28 having a pair of flanges 30 inclined inwardly towards each other to define a groove therebetween. Positioning lugs 32 to position and engage the shield restraining means 42 are located at opposite edges of the mounting plate means 28 intermediate the flanges 30.

The shield support means 34 comprises a curved web portion 36 having a pair of circumferential dished flange portions 37 extending therefrom and adapted to slidably mate with the inwardly inclined flanges 30 of the mounting plate 28. The shield support means 34 includes a pair of apertures 40 extending through the web portion 36 for co-operation with the shield restraint means 42; a pair of radially extending lug members 38, adjacent each of the apertures 40 co-operate with the shield 50 in securing relation.

The shield restraint means 42 comprises a resilient arcuately curved member having a pair of

flange portions

44, 45, each having a raised

nib

46, 47 intermmediate the ends thereof for frictional engagement with the adjacent surface portion 36 of the shield support means. Recessed end lip members 43 of the shield restraint means 42 engage with a positioning lug 32 of the mounting plate means 28, to position the shield restraint means relative to the mounting plate means.

A shield member 50 is of arcuate form, having a pair of stiffening lips 52 defining the longitudinal edges thereof. Apertures 51 on opposite sides of the shield are adapted to receive radially extending lug members 38 of the shield support means 34.

Referring to FIGURE 3 and the embodiment illustrated therein, shield 54 is of arcuate shape having longitudinal flanges 56. Secured to the surface of each flange 56 is a soft paint absorbing material 58 so that contact of the work surface by one of the longitudinal edges of the paint shield will minimize blotching of the painted surface. As will be seen most clearly in FIGURE 3, the arcuate portion of splash shield 54 is formed in a series of regular arcuate transverse grooves 60 to retain paint splashings from longitudinal movement along shield 54 to spill over an edge 62. Elevations 66 formed adjacent recesses 64, are adapted for engagement with apertures 40 of shield support means 34, point 68 being adapted to overlie the edge of said aperture 40 to prevent accidental removal of shield 54 from shield support means 34. Lugs 38 are removed from support means 34 for use with shield 54.

Adaptor 70 comprises a tubular portion 72 to loosely encircle channel member 26 of shield attachment means 22. Locking means 74, such as a thumbscrew threaded into tubular portion 72, penetrates tubular portion 72 at 76 to securely clamp channel member 26 and permit axial adjustment of said member 26 therein. Channel member 78, formed in an obtuse angle as illustrated most clearly in FIGURE 3, engages arm 80 of roller assembly 81. Channel member 78 is broadened at 82 to accommodate roller assemblies having arms 80 of various angles at point 84 in the arm as illustrated. As will be clearly seen in FIGURE 3, tubular member 72 is formed integral with channel member 78 at juncture point 86.

In operation it will be seen that the shield restraining means 42 acts as a friction brake against the outside surface of the web portion 36 of the shield support means 34, while in the extreme positions the

nib members

46, 47 engaged with the apertures 40 of the shield support means to provide positive stop means thereto. The lip portion 52 of the shield 50 also overlies the channel form of the shield support means 34, and acts in cooperation with the mounting plate means 28 to further prevent accidental disassembly of the splash shield when in operation. Adaptor 70 as described hereinabove will make the invention of the instant application more versatile, by making shield attachment means 22 readily usable with paint roller units having arms of varying shapes and dimensions. At the same time, grooves 60 will collect and retain splashed paint and restrict its movement, minimizing the possibility of the paint running to one edge of the shield and spilling over.

It will be seen that in use the present invention provides a readily movable shield which is infinitely variable between two extremes of position, and may be readily positioned within the range of movement by a light contact of the edge of the shield member 50 against the surface being painted.

In addition to the foregoing advantages, the present invention provides a readily assembled and disassembled splash shield formed of four major components, each of which may be readily die-cast from plastics, thus providing an inexpensive and readily cleaned series of components.
