Referring to
The paint brush 10 generally includes an elongated handle 14 having a flat front face 21, a flat rear face 23, and left and right sides 31, 33 respectively connecting the flat front and rear faces 21, 23. The respective flat front and rear faces 21, 23 each have a lower portion 21a proximate the bristles 16, an intermediate portion 21b, and an upper portion 21c distal the bristles 16. As shown, the respective lower portions 21a of the flat front and rear faces 21 and 23 proximate the bristles 16 may be wider than the respective intermediate portions 21b, and the flat front and rear faces 21 and 23 may each have a width that tapers from the lower portion 21a toward the intermediate portion 21b. The tapered surfaces may taper either in a continuous linear fashion, or in a curved fashion, as shown in
The handle 14 includes a major portion 20 which may provide the main structural support of the handle 14 and the main gripping surface of the handle 14. Located on the opposite front and rear flat faces 21, 23 of the major portion 20 of the handle 14 are grip pads 22 integrated with the major portion 20, which in the illustrated embodiment are mirror images of each other. As shown, the grip pads 22 may constitute a large region of the major portion 20. For example, the perimeter of each of the front and rear grip pads 22 defines a respective grip pad area 43, and each of the regions of the respective lower portions 21a surrounding the front and rear grip pads 22 defines a bezel 30, 32 having a bezel area 24, in which the respective grip pad areas 43 are greater than the respective bezel areas 24. The grip pads 22 also may have a shape that corresponds to the shape of the lower portion 21a of the handle. For example, in the illustrated embodiment, the perimeter of each grip pad 22 tapers from the wider lower portion of the grip pad 22 toward the narrower upper portion of the grip pad 22.
The grip pad(s) 22 form discrete segments of the overall handle 14, which is/are operatively integrated to the major portion 20 in any suitable manner, including by way of mechanical features (mechanical fasteners, projections, etc.), adhesives, sonic welding, or the like. For example, the grip pads 22 may be bonded or fastened to the major portion 20 of the handle 14. Alternatively, the grip pad 22 could be formed as a continuous band around the major portion 20, such as within in a recess circumscribing the major portion 20. The grip pad(s) 22 may have any suitable configuration to provide improved comfort or ergonomics of the design. The grip pads 22 may have an exposed surface that is flush or essentially flush with the adjacent outer surface of the major portion 20. In the illustrated embodiment, the grip pads 22 on each flat face 21, 23 are the same configuration and same material, although it is understood the grip pads 22 could be provided with different configurations (shapes, locations, etc.) and/or different materials. As shown, the grip pads 22 are provided at the lower (enlarged) portion 21a of the handle 14 where the user's fingertips generally rest during a coating process.
In the illustrated embodiment, the grip pads 22 include a textured area including texturing 42. As shown, the grip pads 22 may include a rim 51 that surrounds the texturing 42. The textured area (texturing 42) may be recessed relative to an upper surface 53 of the rim 51 to provide a recessed area 40 relative to the rim 51 and/or flat faces 30, 32 of the handle 14. The grip pad 22 also may include a tapered surface 55 that extends inwardly from the rim 51 toward the base 45 of the at least one grip pad 22 and surrounds the textured area (texturing 42).
The texturing 42 may be in any suitable form to provide a tactile feel and/or improve grip for the user. In the illustrated embodiment, the texturing 42 is in the form of discrete protrusions 44 extending upright from a base 45 of the recessed area 40 of the grip pad 22. The protrusions 44 may be at least partially or wholly surrounded by the bezel 30 of the major portion 20 of the handle 14. As shown, the upright protrusions 44 may have a flat upper surface and/or may be spaced apart from each other in a uniformly spaced array. To improve the tactile feel and/or grip, each of the plurality of protrusions 44 may be independently compressible and resiliently movable relative to each other. The protrusions 44 can be solid structures (as shown in
To integrate the grip pads 22 with the major portion 20, the grip pads 22 may be disposed in respective pockets 50, 52 in the lower portion 21a on opposite sides of the brush 10. The grip pads 22 may be attached in their respective pockets 50, 52 by adhesive. The pockets 50, 52 may include one or more holes 54 extending into the brush, improving the coupling of the pads 22 to the major portion 20. In exemplary embodiments, the grip pads 22 are made by a molding process, such as injection molding, or other suitable process, such as additive manufacturing, and are then operatively coupled within the pockets 50, 52 via a suitable technique, such as with mechanical features (mechanical fasteners, projections within the holes 54, etc.), adhesives, sonic welding, or the like. The holes 54 could also include an undercut or taper for mechanical securement; or could include an adhesive therein for bonding securement.
To couple the grip pads 22 together, holes 54 may be through-holes extending between the pair of pockets 50, 52, allowing opposite grip pads 22 to be operatively coupled together via the through hole(s) 54. In exemplary embodiments, the grip pad 22 material may be deposited (e.g. molded) into the respective pocket 50, 52 in such a way that the material flows into at least one through-hole 54 and grip pads 22 are formed in the two pockets 50, 52. In exemplary embodiments, the grip pads 22 are integrated with the major portion 20 of the handle 14 via an over-molding process. For example, the grip pads 22 may be directly formed via injection molding into the pockets 50, 52. During the injection molding process, the fluid material of the grip pads 22 may flow through the through-holes 54 to combine the grip pad material from opposite pockets 50, 52 and form a unitary structure upon cooling. This forms a strong coupling of the grip pads 22 with the major portion 20 and also minimizes the number of assembly steps.
The major portion 20 of the handle 14 may be made with any suitable material or combination of materials in any suitable manner to provide the desired structural support, stiffness, strength and/or overall shape of the handle 14 as may be desired for the particular application. In exemplary embodiments, the major portion 20 is made with suitable rigid polymer(s), wood, composite material, or combinations thereof. In the illustrated embodiment, for example, the major portion 20 is made of wood which is shaped by machining techniques into the desired overall shape. In alternative embodiments, the major portion 20 may be molded from thermoset or thermoplastic polymer, such as polypropylene (PP), polyamide (PA), polyoxymethylene (POM), or polycarbonate (PC), or any other suitable rigid plastic material, preferably which is impervious to many paint solvents. These rigid materials may generally have a rigidity (stiffness) that is greater than about 1 GPa, such as in a range from 1.0 GPa to about 20 GPa, as measured by elastic modulus or flexural modulus testing. For example, the elastic modulus of wood may be about 10 GPa, such as in a range from 10 GPa to 20 GPa. The flexural modulus of PP may be about 1.00 GPa (such as in a range from 1-2 GPa), or about 3 GPa to 10 GPa with glass fiber-reinforcement. The elastic modulus of PC may be about 2.00 GPa (such as in a range from 2-3 GPa); or about 3-7 GPa if blended with another polymer; or in a range of about 5-10 GPa with glass fiber-reinforcement. As shown in
The grip pad(s) 22 may be formed to have a greater flexibility and/or resiliency than the major portion 20 to enhance the comfort and/or ergonomics of the paint brush 10 design. For example, the major portion 20 may be made of a first material and the one or more grip pads 22 may be made of a second material different from the first material, wherein the first material has a greater elastic modulus or flexural modulus than the second material. This provides the major portion 20 of the handle 14 with greater rigidity than the one or more grip pads 22. The increased flexibility of the grip pad(s) 22 may at least partially be attributed to the type of material of the grip pad 22 which may have an elastic modulus or flexural modulus that is greater than that of the more rigid major portion 20.
In exemplary embodiments, the grip pad(s) 22 may be made of a flexible material, such as an elastomer (e.g., one or more resilient elastomeric materials). The grip pads 22 may be made of the same material, and each of the front and rear grip pads 22 may be made with a resilient elastomeric material having a greater flexibility than respective bezel regions 30, 32 of the lower portions 21a that surround the front and rear grip pads 22. For example, the grip pad(s) 22 may be made of a thermoplastic elastomer (TPE) material, including thermoplastic rubber (TPR), thermoplastic olefin (TPO), thermoplastic polyurethane (TPU) or thermoplastic vulcanizate (TPV), or any other suitable material or combinations of such materials. These flexible materials may generally have a flexibility that is at least an order of magnitude less than that of the rigid major portion 20, as measured by elastic modulus or flexural modulus testing. For example, the elastic modulus of a TPE may be in a range from about 4.0 MPa to about 200 MPa.
