Abstract

A silicone paint brush artist'"'"'s tool includes a handle and a novel painting tip. The painting tip is made of a resilient silicone having a generally three-dimensional paint contacting working surface that has a maximum cross-sectional diameter no larger than a maximum cross-sectional diameter of the handle. The tip is preferably attached to the handle using a ferrule and expansively locking the tip into a cavity of the ferrule by insertion of an insert. The insert may be a common screw or a barbed, fluted extension of the handle. The tips may include an insert cavity and have various shapes and hardnesses and may be optionally color coded. A formation method for the tool is disclosed with simultaneous insert insertion and joining of ferrules to handles. The ferrules also may be reversibly attached to the handle, in which case a kit comprising multiple interchangeable painting tips may be provided.

Claims

1. A method of forming an artist'"'"'s tool for application and manipulation of paint on a substrate, the method comprising the steps of:

providing a handle, the handle having a distal end and a proximal end;

providing a rigid ferrule adapted for attachment to the distal end of the handle so as, when attached, the ferrule extends distally from the handle and defines a tip carrying cavity adjacent the distal end of the handle;

providing a tip, formed of resilient silicone, the tip having a distally located paint contacting portion and a proximally located ferrule connecting portion;

inserting the tip into the ferrule with the ferrule connecting portion of the tip situated in the tip carrying cavity of the ferrule and the paint contacting portion extending distally from the ferrule;

expanding the ferrule connecting portion of the tip into locking contact within the tip carrying cavity of the ferrule by installing an insert into the ferrule connecting portion of the tip;

attaching the ferrule, with the tip inserted in the tip carrying cavity, to the distal end of the handle, thereby forming the device for application and manipulation of paint on a substrate.

2. The method of claim 1 wherein the insert has helical threads and the installation of the insert includes rotation of the insert so as to longitudinally advance the insert into the ferrule connecting portion of the tip.

3. The method of claim 1 wherein the handle is plastic and the insert is a distally directed extension of the handle.

4. The method of claim 1 wherein the installation of the insert into the tip occurs in conjunction with the attachment of the ferrule to the distal end of the handle.

5. The method of claim 1 wherein the ferrule connecting portion of the tip includes an insert cavity to facilitate and direct longitudinal installation of the insert and the insert cavity is generally transversely undersized relative to the insert such that upon installation of the insert, the ferrule connecting portion of the tip expands into locking contact with the tip carrying cavity of the ferrule.

6. The method of claim 5 wherein the insert and the insert cavity have complementary longitudinally extending flutes to resist rotation of the insert relative to the tip.

7. The method of claim 5 wherein the insert has at least one barb to resist extraction of the insert from the ferrule connecting portion of the tip.

8. The method of claim 1 wherein the step of attaching the ferrule to the handle includes crimping of the ferrule to the handle and the insert.

9. The method of claim 1 wherein the step of attaching the ferrule to the handle is reversible.

10. A method of forming an artist'"'"'s tool for application and manipulation of paint on a substrate, the method comprising the steps of:

providing a handle, the handle having a distal end and a proximal end, the distal end having an integral insert extending therefrom;

providing a rigid ferrule adapted for attachment to the distal end of the handle so as, when attached, the ferrule extends distally from the handle and defines a tip carrying cavity adjacent the distal end of the handle;

providing a tip, formed of resilient silicone, the tip having a distally located paint contacting portion and a proximally located ferrule connecting portion;

inserting the integral insert of the handle into the ferrule connecting portion of the tip;

placing the ferrule over the ferrule connecting portion of the tip and the distal end of the handle; and

crimping the ferrule to lock the tip to the handle.

11. The method of claim 10 wherein the ferrule is crimped to the handle and to the tip.

12. The method of claim 10 and wherein the ferrule is tapered.
