Broadly described, the present invention, as exemplified in the accompanying drawings, relates to a roller frame for supporting a roller and also, for example, if need may be, for allowing a corresponding rotation of said roller with respect to the roller frame, as is often necessary for painting applications, and the like. The roller frame may comprise a base component, as well as first and second supporting components operatively projecting from the base component, each supporting component having a mounting cap for receiving a corresponding distal end of the roller, with at least one, but preferably, both, of the first and second supporting components, being angularly adjustable with respect to the base component via a tightening assembly for allowing the roller to be selectively positioned at different angles with respect to the base component of the roller frame, as can be easily understood when referring to the accompanying drawings.

As can also be easily understood from the drawings, each supporting component may have a substantially rigid component and a substantially flexible component, the roller frame comprising first and second mounting caps being provided on the flexible components of the first and second supporting components respectively, said supporting components being operable between a “drawn-out” configuration where the roller is insertable between the first and second mounting caps, and a “drawn-in” configuration where the first and second mounting caps are inserted into first and second distal ends of the roller respectively.

As can also be easily understood, the first and second mounting caps can be positioned, shaped and sized for press-fittingly receiving the first and second distal ends of the roller, and according to a possible embodiment, each mounting cap is pivotably mounted about a corresponding flexible component of the roller frame via a corresponding pivot assembly, so that the roller inserted into the first and second mounting caps rotates with said mounting caps, via the pivot assembly.

The pivot assembly may include a pin bearing, and as better shown in FIG. 16, for example, and the pin bearing may be molded within a corresponding hub section of the flexible component.

Optionally also, the pin bearing may be provided with at least one securing flange for securing the pin bearing within the hub section molded about the pin bearing and corresponding at least one securing flange. According to one possible embodiment, the at least one securing flange is mounted about a portion of a shaft of the pin bearing, said at least one securing flange and portion of the shaft of the pin bearing having a substantially T-shaped cross-sectional profile. Alternatively, and according to another possible embodiment, the at least one securing flange includes a pair of securing flanges being mounted about a portion of a shaft of the pin bearing, said pair of securing flanges and portion of the shaft of the pin bearing having a substantially H-shaped cross-sectional profile, as better shown in FIG. 18, for example.

As shown in FIGS. 16 and 18, for instance, the pin bearing may be provided with at least one retaining component being positioned, shaped and sized about an inner part of each mounting cap for retaining said mounting cap against a corresponding flexible component of the roller frame.

Optionally also, each mounting cap may comprise a receiving body and an abutment flange, the abutment flange being positioned, shaped and sized for abutting against a corresponding rim of the roller. The receiving body of each mounting cap may be provided with at least one circumferential protuberance for increasing a press-fitting interaction with the roller, and the at least one circumferential protuberance can be provided circumferentially (ex. continuously and/or discontinuously) about the receiving body of the mounting cap.

As better shown in FIGS. 14-16, for example, each flexible component of each supporting component may be substantially L-shaped, including a substantially fixed mounting portion and a substantially resilient moveable portion.

According to a possible embodiment, each flexible component of each supporting component is provided with an arched section for facilitating corresponding lateral deviation (and/or “bending”, “spreading apart”, etc.) of the flexible component of the supporting component.

According to another possible embodiment, the mounting portion of each flexible component of each supporting component is mechanically connectable to a corresponding support rod being pivotably rotatable with respect to the base component of the roller frame.

Optionally, the mounting portion of each flexible component of each supporting component may include a bore for receiving a corresponding extremity of the support rod, and the bore may be provided with a male component being removably insertable into a corresponding distal end of the support rod, as better shown in FIGS. 16 and 18, for example.

Optionally also, the mounting portion of each flexible component of each supporting component is securely connectable to the corresponding support rod via at least one fastener insertable into the mounting portion and into the support rod.

The support rod may be a hollow support rod, for example. This has the advantage of reducing the amount of material being used for manufacturing and assembling the roller frame, and also enables for a “lighter-weight” roller frame. The roller frame may also include a common support rod for receiving the mounting portions of both the first and second supporting components of the roller frame, so that rotation of one in turn a rotation of the other, and vice-versa.

As better shown in FIGS. 19, 20 and 21, for example, this illustrates how the same components of a given roller frame can be used with support rods of varying lengths to accommodate different lengths of paint rollers, and further shows how the present system enables a manufacturer, a distributor, a wholesaler and/or a retailer, to have a reduced number of parts, inventory, etc., which is also advantageous, for obvious reasons.

The support rod may comprise at least one hole for receiving a corresponding fastener, and according to a possible embodiment, the support rod comprises a pair of lateral or side holes for receiving first and second fasteners intended to securely connect the mounting portions of the first and second supporting components respectively onto the support rod.

As better shown in FIGS. 16, 25, 26 and 27, for example, the base component comprises a corresponding sleeve being positioned, shaped and sized for receiving the support rod, the sleeve being provided with at least one slit for defining first and second clamping portions of the sleeve configured to move with respect to one another, in order to be selectively operated in a “clamping” configuration where the first and second clamping portions of the sleeve are securely clamped against the support rod so as to securely immobilize the same, and an “adjustment” (or “rotating”, “pivotating”, etc.) configuration where the support rod is allowed to adjustably rotate with respect to the sleeve and corresponding base component of the roller frame.

The roller frame may also comprise a rubberized tube being provided about a portion of the support rod contained within the sleeve of the base component for assisting in a frictional engagement between the sleeve and corresponding support rod when the latter is selectively secured by the tightening assembly.

According to a possible embodiment, the rubberized tube may comprise a main hole being complementary to the main hole of the support rod, and through which the adjustment component of the tightening assembly is intended to pass, etc.

As shown, in the accompanying drawings, the base component may be configured to have a substantially T-shaped profile, and so that the sleeve extends along a top portion (i.e. “cross portion”, for example) of the base component.

A bottom portion of the of the base component may be provided with an inner cavity being positioned, shaped and sized to cooperate with a complementary tool to be used with the roller frame, and more particularly, the bottom portion of the base component may be threaded for threadedly receiving a corresponding extension pole, for example.

Referring back to the support rod, it may comprise a main hole for receiving a corresponding adjustment component of the tightening assembly.

According to a possible embodiment, the adjustment component is positioned, shaped and sized for extending through the base component of the roller frame (and/or corresponding sleeve thereof, for example), and optionally also, the adjustment component is threaded and is configured for cooperating with a corresponding threaded tightening knob, in order to selectively urge first and second clamping portions of the base component (ex. first and second clamping portions of the sleeve) towards one another, in order to in turn selectively maintain the support rod and corresponding supporting components of the roller frame at a fixed operating angle.

According to a possible embodiment, the tightening knob may be provided with at least one tightening lever, and more particularly, may be provided with three tightening levers, for example, these tightening levers being spaced angularly equidistantly from one another about the tightening knob, for example, as better shown in FIGS. 25-27, for instance.

Of course, various other types, shapes, forms and/or configurations of tightening knobs, with various other types and/or numbers of gripping portions, may be used for the present roller frame, as can be easily understood by a person skilled in the art.

Irrespectively of the nature of the tightening knob and/or tightening mechanism used for the tightening assembly, an object of the present system is to provide a roller frame capable of being adjustable with respect to a base component thereof, in order to selectively choose an optimal and/or preferred operating angle of work (ex. for painting, etc.) with the roller frame. Indeed, the way in which one and/or both of the first and second supporting components of the roller frame are angularly adjustable with respect to the base component via the tightening assembly for allowing the roller to be selectively positioned at different angles with respect to the base component of the roller frame, can take on various different shapes, forms and/or configurations, as can also be easily understood by a person skilled in the art.

For example, according to a one possible embodiment, the adjustment component of the tightening assembly may be positioned, shaped and sized for extending along at least one slot (ex. a “guiding” slot, an “adjustment” slot, a “selection” slot, etc.) defined about the base component, and more particularly, about a corresponding side and/or portion of said base component.

For example, the roller frame may comprise front and rear slots being provided respectively about front and rear sides of the base component.

As can be easily understood when referring to the accompanying drawings, each slot may be provided with different surface segments corresponding to different positions of the adjustment component, thereby in turn causing the first and second supporting components of the roller frame to rotate with respect to the base component via the tightening assembly, for allowing the roller frame to be selectively positioned at different incremental angles with respect to the base component.

Optionally also, the different surface segments of each slot are positioned, shaped and sized so as to allow the first and second supporting components to rotate with respect to the base component along angle increments, the angle increments being selected from the group consisting of about 5, 10, 15, 20, 25, 30, 35, 40, 45 and 90 degrees, for example. Other types of angle increments may also be used for the present roller frame, depending on the particular applications for which the roller frame is intended for, and the desired end results, etc.

According to a particular possible embodiment, the different surface segments of each slot are positioned, shaped and sized so as to allow the first and second supporting components of the roller frame to rotate with respect to the base component between two different major angle configurations. In most of the embodiments shown in the accompanying drawings, for example, the roller frame is configured so that a first major angle configuration is about 0 degree(s) with respect to a longitudinal axis of the base component, and so that a second major angle configuration is about 30 degrees with respect to the longitudinal axis of the base component. Of course, and once again, various other types and/or numbers of angle configurations, may be used for the present roller frame, as can be easily understood by a person skilled in the art.

According to yet another possible embodiment, each slot is provided within a corresponding recessed portion defined about the base component, the recessed portion comprising a corresponding peripheral wall for guiding movement of a corresponding component of the tightening assembly. Optionally, the front slot may comprise and/or be contained within a corresponding front recessed portion defined about the base component, the front recessed portion comprising a corresponding peripheral wall for guiding movement of a corresponding component (ex. washer, tightening knob, etc.) of the tightening assembly. Optionally also, the rear slot may comprise and/or be contained within a corresponding rear recessed portion defined about the base component, the rear recessed portion comprising a corresponding peripheral wall for guiding movement of a corresponding portion (ex. head, etc.) of the adjustment component of the tightening assembly, and thus, the adjustment component of the tightening assembly may be a bolt, for example.

Similarly to what was previously explained, irrespectively of the nature of the adjustment mechanism/manner and/or tightening assembly used for the present roller, the present roller frame is meant to be capable of being adjusted in angle with respect to a base component, in order to selectively choose an optimal and/or preferred operating angle of work (ex. painting, etc.) for the roller frame. Indeed, the way in which one and/or both of the first and second supporting components of the roller frame are angularly adjustable with respect to the base component can come in various different shapes, forms and/or configurations, as can also be easily understood by a person skilled in the art.

According to one possible intended use, the roller frame is a paint roller frame configured for receiving a corresponding paint roller being removably mountable onto the first and second mounting caps, although it is worth mentioning, once again, that the present roller frame could be used to spread various other types of liquid-type substances (ex. varnish, epoxy, tar, etc.), that is, substances capable of shear, and meant to be distributed and/or spread over a given work surface, etc., as can also be easily understood by a person skilled in the art.

As may now better be appreciated, the present invention is a substantial improvement over the prior art in that, by virtue of its design and components, as explained hereinabove, the present roller frame enables a user, to carry out panting applications and/or work with corresponding paint rollers, for example, in a more efficient, more precise, more accurate, more reliable, more adjustable, more versatile, more adaptable, more ergonomic and/or more desirable manner, compared to what is possible with respect to other known conventional paint roller frames and/or painting methods.

When compared to other conventional paint roller frames, the present roller frame is also quite advantageous in that: a) the handle can be conveniently rotated from one operating angle (ex. 0°, when working on “walls”, for instance) to another operating angle (ex. 30°—when working on “floors”, for instance); b) it enables an “even pressure” on both sides of the roller cover; c) it does not have “loose” parts, and stays in one piece while painting; d) it helps a user to minimize getting dirty with paint because the user can simply use and operate (i.e. “spread-apart”) the flexible arms of the roller frame, without touching the actual roller; e) etc.

Indeed, and as also previously explained, the present system is particularly advantageous in that, due to its components and features, it enables namely to offer a paint roller frame capable of being selectively adjustable with respect to a base component thereof, in order to, for example, selectively and incrementally choose an optimal and/or preferred operating angle of painting, depending on the particular circumstances, intended results, and/or various other considerations, factors, etc.

Of course, and as can be easily understood by a person skilled in the art, the scope of the claims should not be limited by the possible embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.

Furthermore, although preferred embodiments of the present invention have been briefly described herein and illustrated in the accompanying drawings, it is to be understood that the invention is not limited to these embodiments and that various changes and modifications could be made without departing from the scope and spirit of the present invention, as defined in the appended claims and as apparent to a person skilled in the art.
