Abstract
A paint brush includes a handle having an attachment end and a grip end. The attachment end has an overall width larger than the grip end. A plurality of bristles is coupled to the attachment end of the handle by a resin. An extension extends from the attachment end of the handle into the resin and toward the plurality of bristles. The extension has a substantially planar surface that faces the plurality of bristles. A groove is formed within the extension and has an opening on the planar surface facing the plurality of bristles. The opening is sized and shaped to allow resin to at least partially fill the groove so as to further reduce independent movement of the handle with respect to the plurality of bristles.
Description
- This patent application is a Continuation application and claims benefit of U.S. patent application Ser. No. 11/825,525, filed on Jul. 6, 2007, which is incorporated by reference herein in its entirety for all purposes.
- 1. Field of the Invention
- The present invention relates generally to paint brushes.
- 2. Related Art
- Traditional paint brushes have an elongated handle with bristles, filaments, or other application medium attached to an end of the elongated handle. Often, the bristles are attached to the handle by way of a sleeve or “ferrule” that circumscribes an end of the bristles and a mating end of the handle. A plug is often placed between the bristles to spread the bristles outward toward the sleeve so that the bristles are wedged between the plug and the sleeve. The bristles and plug are often adhered together by commonly known adhesives, such as epoxy resins and the like. Together the bristles, the plug, and the adhesive form a “knot” that retains the bristles in the sleeve. Additionally, the sleeve can be adhered to the handle by way of a common adhesive, and/or other types of fasteners such as screws, nails, brads, and the like.
- In use, the bristles or filaments of the paint brushes are dipped into a liquid coating, such as paint, stain, and the like, so that coating is collected on the bristles. The coating can then be transferred from the bristles to a surface by pressing the coating covered bristles onto the surface and moving the brush across the surface. When nearly all of the coating has been transferred from the bristles to the surface, the brush must be dipped back into the paint to collect more paint that can then be transferred to the surface.
- Many attempts have been made to improve the traditional paint brush. For example, many paint brushes have plastic handles instead of wood handles. Additionally, some paint brushes have hollow handles that can be filled with paint which runs out of the handle and into the bristles while painting so as to reduce the frequency of dipping the brush into the paint.
- Unfortunately, traditional paint brushes, and even many of the improvements made to such brushes, continue to present problems to painters. For example, frequent dipping of the brush into the paint reduces the overall efficiency of a painter. It will be appreciated that the time required to dip a brush reduces time the painter could be brushing paint onto a surface. Thus, reducing the need to dip the brush to collect more paint increases the productivity and overall efficiency of a painter. Unfortunately, attempts to increase the paint reservoir in a brush, such as the hollow handle that can be filled with paint, are difficult to clean up and can easily become clogged with dried paint.
- Another common issue with traditional paint brushes is that many painters prefer to use a brush with very fine bristles or filaments with relatively small diameters, because of the feel and precision of the brush during a brush stroke and the smoothness of the surface finish of the resulting coat of paint. Unfortunately, finer bristles and smaller filaments cause a floppier or weaker brush.
- Yet another problem with traditional brushes is that they have a generally square shape with a brush face oriented perpendicular to the sides of the brush. It will be appreciated that painting many surfaces requires the painter to gradually apply pressure to a brush against the surface so as to blend in or “feather” new paint on top of paint already on the surface. Unfortunately, a brush face perpendicular to the sides of the brush as found on traditional paint brushes makes such feathering difficult to accomplish.
- Additionally, many painters prefer the feel of traditional wood handles over newer plastic handles, however, traditional wood handles, over time, absorb paint and solvents which tend to swell and contract the handle, thereby loosening the handle or brush knot in the ferrule. This loosening can cause the handle to move in relation to the brush head. It will be appreciated that such movement can make it difficult to precision paint.
- The inventors of the present invention have recognized that it would be advantageous to develop a method and device for increasing the strength of the connection between a brush head and a handle so as to reduce movement of the handle in relation to the brush head.
- Accordingly, in one aspect, the present invention provides for a paint brush including a handle having an attachment end and a grip end. The attachment end can have an overall width larger than the grip end. A plurality of bristles can be coupled to the attachment end of the handle by a resin. An extension can extend from the attachment end of the handle into the resin and toward the plurality of bristles. The extension can have a substantially planar surface that faces the plurality of bristles. A groove can be formed within the extension and can have an opening on the planar surface facing the plurality of bristles. The opening can be sized and shaped to allow resin to at least partially fill the groove so as to further reduce independent movement of the handle with respect to the plurality of bristles.
- Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention.

It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated herein, and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.
- The embodiments of the present invention described herein generally provide for a paint brush having a greater paint carrying capacity. The paint brush can include a plurality of filaments that collectively form a brush head. A plug can be inserted into an end of the brush head so as to form a space between the plurality of filaments. The space between the filaments can act as a paint reservoir that can store paint in the brush head. The plug can have a concave end that faces the space formed between the filaments. The concave end can increase the size of the paint reservoir so that more paint can be stored in the brush head.
- It is noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
- Additionally, as used herein, “plurality” refers to more than one. For example, a plurality of filaments refers to at least two filaments.
- As used herein, the term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint. The degree of flexibility of this term can be dictated by the particular variable and would be within the knowledge of those skilled in the art to determine based on experience and the associated description herein.
- As used herein, a plurality of components may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary.
- As used herein, the term “filament” refers to any fiber, strand, or string-like element which, when placed with other fibers or strands, can form a brush head. For example, a filament can be a natural fiber, such as animal hair, or a synthetic fiber, such as nylon string, polybutylene strands, and the like. Additionally, the terms filament, fiber, and bristle may be used interchangeably throughout this description.
- As used herein the term “brush” refers to any collection of filaments or bristles coupled to a handle for purposes of transferring a chemical from the brush to a surface. For example, a brush can be a paint brush that can transfer paint, lacquer, varnish, stain, water sealant, and the like from a container to a surface.
- Thus, as illustrated in
FIGS. 1-2 , a brush, indicated generally at 10, in accordance with an embodiment of the present invention is shown for use transferring coatings such as paint, stain, lacquer, varnish, clear coat, water sealant, and the like to a surface. In one aspect, thebrush 10 can be a paint brush. Thebrush 10 can have a plurality offilaments 20, and aplug 50 disposed in the filaments. - The
filaments 20 can be formed of a natural or synthetic material, and collectively the plurality offilaments 20 can form a brush head, indicated generally at 22. Thebrush head 22 can have anapplication end 24 and anattachment end 26. - It will be appreciated that the
application end 24 can be variety of shapes and angles with respect to thelongitudinal axis 28 of the brush head. For example, in one aspect, theapplication end 24 can have an arcuate cross section, as shown inFIG. 1 . In another aspect, theapplication end 24 can have a substantially flat cross section perpendicular to thelongitudinal axis 28 of the brush head, as shown inFIG. 2 . Additionally, theapplication end 24 can have an angled orientation with respect to alongitudinal axis 28 of the brush. - Referring to
FIGS. 1-3 , theplug 50 can be disposed between thefilaments 20 near theattachment end 26 of thebrush head 22. In one aspect, theplug 50 can separate thefilaments 20 into approximatelyequal halves 30 of thebrush head 22, and can form aspace 40 between the halves. Thespace 40 can form a reservoir that can store coating material when thebrush 10 is dipped into a coating material. - Additionally, the
plug 50 can have aconcave end 52 formed in the plug. Theconcave end 52 can extend along a longitudinal length, L, of theplug 50. Theplug 50 can be positioned in thefilaments 20 such that theconcave end 52 faces, or is open to, thespace 40 formed between the filaments. In this way, theconcave end 52 advantageously increases the size of the reservoir such that thebrush head 22 can store more coating material than a brush head having a plug with a flat end. - The
plug 50 can be formed a substantially non-permeable material such as a polymer, a closed cell foam, a plastic, and the like. In this way, theplug 50 can resist absorption of the coating material. It will be appreciated that aplug 50 made of a permeable material can absorb the coating material which can make thebrush 10 difficult to clean and can cause theplug 50 to swell and deform. When such deformation of the plug occurs, the plug can affect the shape of the brush head. In contrast, the non-permeable material used in theplug 50 of the present invention resists absorption of the coating material and, thus, advantageously retains the size and shape of thebrush head 22 and facilitates cleaning of the brush. - The
brush 10 can also include asleeve 70 circumscribing the ends of the plurality ofbristles 20 forming theattachment end 26 of thebrush head 22. Thesleeve 70 can also circumscribe theplug 50 such that the plug can wedge the ends of the plurality ofbristles 20 forming the separated halves 30 of theattachment end 26 of thebrush head 22 against thesleeve 70. In this way, thesleeve 70 can clamp and hold thebrush head 22 and plug 50 in place. Accordingly, thesleeve 70 can be a ferrule, as known to those of skill in the art. - The
sleeve 70 can be formed of a suitably rigid plastic or metal material so as to provide the clamping force on thebristles 20 disposed between theplug 50 and thesleeve 70. Additionally, thesleeve 70 can be formed of a substantially non-permeable material so as to resist absorption of the coating material. - The
brush 10 can also include aresin 80 disposed within thesleeve 70. Theresin 80 can surround theplug 50 and the ends of thefilaments 20 forming theattachment end 26 of thebrush head 22. In this way, theresin 80 can hold the ends of the plurality ofbristles 20 and theplug 50 together within thesleeve 70. Theresin 80 can be an adhesive type resin, an epoxy type resin, an epoxy resin with adhesive properties, and the like. Together, theresin 80, theplug 50, and theattachment end 26 of thebrush head 22, can form a brush knot, indicated generally at 60. Thebrush knot 60 can hold thebrush head 22 in place in relation to thesleeve 70. - The
brush 10 can also include ahandle 90 circumscribed by thesleeve 70 and coupled to theattachment end 26 of thebrush head 22 by thesleeve 70. Thehandle 90 can have anattachment end 92 and agrip 94. Theattachment end 92 can be circumscribed by thesleeve 70 and can be attached to the ends of thefilaments 20 forming theattachment end 26 of thebrush head 22. Theresin 70 can attach theattachment end 92 of thehandle 90 to theattachment end 26 of thebrush head 22. - The
grip 94 can extend away from theattachment end 92 of thehandle 90 and away from thebrush head 22. Thegrip 94 can be sized and shaped to be held in the hand of a user. - A
reinforcement bracket 96 can be disposed within the resin and can extend around theattachment end 92 of thehandle 90. Thereinforcement bracket 96 can reinforce the attachment of thehandle 90 to thebrush head 22. Thereinforcement bracket 96 can be formed of a metal material or a rigid polymeric material. - A plurality of
fasteners 98 can attach thesleeve 70 to theattachment end 92 of thehandle 90. For example, thefasteners 98 can be nails or brads, as shown inFIG. 1 . Thefasteners 98 can extend through thesleeve 70 and into theattachment end 92 of thehandle 90. Other suitable fasteners, such as staples, screws, and the like can also be used to attach the sleeve to the handle. Additionally, adhesives, such as glue, epoxy, and the like, can also be used to attach the sleeve to the handle. - As illustrated in
FIGS. 4-7 , a brush, indicated generally 100, is shown in accordance with another embodiment of the present invention for use in transferring coatings from a container to a surface. Thebrush 100 can be similar in many respects to thebrush 10 described above and shown inFIGS. 1-3 . Accordingly, thebrush 100 can have a plurality offilaments 20 forming abrush head 22, ahandle 90, and asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 92 of thehandle 90. - Additionally, the
brush 100 can have aplug 150 disposed between thefilaments 20 and forming aspace 140 between the plurality offilaments 20. Theplug 150 can separate thefilaments 20 into separatedportions 130 of thebrush head 22, and can form thespace 140 between the separatedportions 130. Thespace 140 can form a reservoir that can store coating material when thebrush 100 is dipped into a coating material. Theplug 150 can also have aconcave end 152 that faces thespace 140 formed between thefilaments 20. Theconcave end 152 can increases the size of the reservoir such that thebrush head 22 can store more coating material than abrush head 22 having a plug with a flat end. - The
plug 150 can also have aflange 154 that can extend from abody 156 of theplug 150 through thespace 140 between thefilaments 20 and into theapplication end 26 of the filaments. Theflange 150 can extend nearly the entire length of thefilaments 20. For example, in one aspect, thefilaments 20 can have a length of approximately 4 inches and the flange can extend approximately 3.75 inches into the bristles. In another aspect, the filaments can extend approximately 3 inches from thesleeve 70 and theflange 150 can extend approximately 2 inches from the sleeve. Advantageously, the length of theflange 150 in relation to the length of thefilaments 20, and the extension of theflange 150 into thebrush head 22 can be adjusted by pulling the filaments 20 a way from theflange 150 and cutting theflange 150 to the desired length within thefilaments 20. - The
flange 150 can have a thickness, indicated as T. The thickness T of theflange 150 can provide a greater stiffness than thefilaments 20 such that theflange 150 can support thefilaments 20 and stiffen thebrush head 22. The thickness T can be predetermined according to a desired stiffness of thebrush 100. Thus, theflange 150 can have a relatively smaller thickness, as shown inFIG. 6 , if a lessstiff brush 100 is desired. Alternatively, theflange 150 can have a relatively larger thickness, as shown inFIG. 7 , if astiffer brush 100 is desired. - The
flange 154 can be formed as a separate piece from thebody 156 of theplug 150 and then attached to the plug. Alternatively, theflange 154 can be integrally formed with theplug 150 and can be non-permeable to resist absorption of the coating material, and facilitate cleaning of thebrush 100. - It is a particular advantage of the embodiments of the
brush 100 of the present invention described herein that theflange 154 can increase the stiffness of thebrush head 22. It will be appreciated that finer, thinner, orsmaller diameter filaments 20 on a brush provide a better feel and greater precision when transferring a coating material to a surface. Additionally,finer bristles 20 can produce a very smooth coating layer, whereas course or larger bristles can variegate the final coating surface leaving a rougher surface finish. Thus, paint brushes with very fine filaments are highly valued by skilled painters. Unfortunately, the stiffness of the filaments is directly related to the thickness or diameter of the filament so that very fine filaments have a relatively low stiffness. It will be apparent that filaments with low stiffness can collapse and become floppy under the weight of a coating material disposed on the filament. For this reason, filament size has been limited to diameters that can maintain the shape of the brush under the weight of a coating on the filaments. Thus, theflange 154 of thebrush 100 of the present invention can, advantageously, reduce the collapse and floppiness of thebrush head 22 when thefilaments 20 are covered and weighted down with the coating material. - As illustrated in
FIGS. 8-9 , a brush, indicated generally 200, is shown in accordance with another embodiment of the present invention for use in transferring coatings from a container to a surface. Thebrush 200 can be similar in many respects to thebrush FIGS. 1-7 . Accordingly, thebrush 200 can have a plurality offilaments 20 forming abrush head 22, ahandle 90, asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 92 of thehandle 90, and aplug 250 with aflange 254 extending from aplug body 256 into theapplication end 26 of thebrush head 22. Theplug body 256 can have aconcave side 252. - Additionally, the
flange 254 can include a plurality offingers 258 extending from theplug 250 into the plurality offilaments 20. The plurality offingers 258 can support the plurality offilaments 20 in order to stiffen thebrush head 22. The plurality offingers 258 can also allow coating material to flow from the reservoir orspace 240 past thefingers 258 to thefilaments 20 on the other side of theflange 250. As shown inFIGS. 8-9 , thefingers 258 can be relatively short extending along anouter end 260 of theflange 250. - As illustrated in
FIGS. 10-11 , a brush, indicated generally 300, is shown in accordance with another embodiment of the present invention for use in transferring coatings from a container to a surface. Thebrush 300 can be similar in many respects to thebrush 10 described above and shown inFIGS. 1-7 . Accordingly, thebrush 300 can have a plurality of filaments forming abrush head 22, ahandle 90, asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 92 of thehandle 90, and aplug 350 with aflange 354 extending from aplug body 356 into theapplication end 26 of thebrush head 22. - Additionally, the
flange 354 can include a plurality offingers 358 extending from theplug body 356 into the plurality offilaments 20. The plurality offingers 358 can support the plurality offilaments 20 to stiffen thebrush 300. The plurality offingers 358 can also allow coating material to flow from thespace 340 or reservoir past thefingers 358 to thefilaments 20 on the other side of theflange 350. As shown inFIGS. 10-11 , thefingers 358 can be relatively long extending from anouter end 360 or periphery of theflange 350 to a position adjacent thebody 356 of theplug 350. - Advantageously, the
fingers stiffer brush 200 can haveshorter fingers 258, as shown inFIGS. 8-9 , and afloppier brush 300 can havelonger fingers 358, as shown inFIGS. 10-11 . Similarly, theflange fingers - As illustrated in
FIGS. 12-14 , a brush, indicated generally 400, is shown in accordance with another embodiment of the present invention for use in transferring coatings from a container to a surface. Thebrush 400 can be similar in many respects to thebrush FIGS. 1-11 . Accordingly, thebrush 400 can have a plurality offilaments 420 forming abrush head 422, ahandle 90, asleeve 70 circumscribing theattachment end 426 of thebrush head 422 and theattachment end 92 of thehandle 90, and aplug 450 with aflange 454 extending from aplug body 456 into theapplication end 426 of thebrush head 422. - Additionally, the
filaments 420 can be positioned to form abrush head 422 into a predetermined shape. For example, as shown inFIG. 12 , thefilaments 420 forming thebrush head 422 can be positioned to form a brush head having a U-shaped cross section. Specifically, in one aspect, the cross section of thebrush head 422 that is in a plane, indicated by dashes lines at 430, perpendicular to a longitudinal axis, indicated by a dashed line at 432, of thebrush 400 or handle 90 can be shaped in the form of the letter U. In this way, the shape of thebrush head 422 can have a concave side that can be concave about a longitudinal axis 434 that is substantially parallel to a longitudinal axis of the brush 432. - It will be appreciated that a U-shaped cross section facilitates applying an even coating to a wide variety of surfaces since the U-shape of the brush head allows a painter to gradually apply, or feather the coating material to the surface. Thus, it is a particular advantage of the embodiments of the
brush 400 described herein that the predetermined shape of thebrush head 422 can facilitate the application of a coating material to a surface, and although only a U-shaped crosssection brush head 422 is shown, other shapes are considered within the scope of the concepts of the present invention. For example, the predetermined shape of the brush head can be an arc, a semi-circle, a U shape, a V shape, and the like. - Conveniently, the predetermined shape of the
brush head 422 can be formed by aplug 450 formed of a similar shape. Thus, as shown inFIGS. 12-14 , theplug 450 can have a U-shaped cross section, and aU-shaped flange 454 can extend from theplug body 456 into theapplication end 426 of thefilaments 420. Theplug 450 can position thefilaments 20 in order to form the predetermined shape of thebrush head 422. In this way, theU-shaped flange 454 can support and position thefilaments 420 of thebrush head 422 into a U-shape. Thus, theplug 450 and theflange 454 can position thefilaments 420 such that the predetermined shape of thebrush head 422 can have a U-shaped cross section in a plane 430 that is oriented substantially perpendicular to a longitudinal axis 432 of thebrush 400. - As illustrated in
FIGS. 15-16 , a brush, indicated generally 500, is shown in accordance with another embodiment of the present invention for use in transferring coatings from a container to a surface. Thebrush 500 can be similar in many respects to thebrushes FIGS. 1-14 . Accordingly, thebrush 500 can have a plurality offilaments 20 forming abrush head 22, ahandle 90, asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 92 of thehandle 90, and aplug 550 with aflange 554 extending from aplug body 556 into theapplication end 26 of thebrush head 22. - Additionally, the
flange 554 can extend from an approximate center of theplug 550 into the plurality offilaments 20, and theplug body 556 can have aconcave side flange 554. In this way, acoating reservoir flange 554. Thus, as either side of thebrush head 22 is applied to a surface, coating material from the reservoir can be transferred from the reservoir to the brush head and onto the surface. - Although the embodiments of brushes described herein, and shown in the figures, only illustrate brush heads having one plug, it will be appreciated that the inventive concepts may be used with brushes that have a sufficiently thick brush head so as to require more than one plug.
- The present invention also provides for a method for making a brush including placing a plurality of filaments into a sleeve such that ends of the plurality of filaments extend beyond the sleeve. A plug can be inserted into the ends of the plurality of filaments to form a space between the filaments. The plug can have a concave end of that faces the space so that the concave end and the space together define a coating reservoir within the plurality of filaments. The plug and the plurality of filaments can be slid into the sleeve so that the plug wedges the filaments against the sleeve.
- The method can also include pouring a resin into the sleeve to contact the plurality of filaments and the plug. A handle can then be inserted into the sleeve so that the sleeve can hold the plurality of filaments, the plug, and the handle together.
- The present invention also provides a method for applying a coating with a brush including dipping a plurality of filaments into a container of coating material such that coating material covers the filaments and fills a reservoir disposed between the filaments. The reservoir can include a concave end of a plug disposed between the filaments. The coating covered filaments can be slid along a surface to transfer the coating from the filaments to the surface. The coating covered filaments can be pressed against the surface to transfer substantially all of the coating in the reservoir to the filaments, including coating in the concave end of the plug. The filaments can be slid again along the surface to transfer additional coating from the reservoir and filaments to the surface.
- As illustrated in
FIG. 17 , a brush, indicated generally at 600, is shown in accordance with another embodiment of the present invention. Thebrush 600 can be similar in many respects to thebrushes FIGS. 1-16 . Accordingly, thebrush 600 can have a plurality offilaments 20 forming abrush head 22, ahandle 690, asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 692 of thehandle 690, and aplug 50 with aconcave end 52 forming aspace 40 between thefilaments 20. - Additionally, the
attachment end 692 of thehandle 690 can have anextension 694 that can extend away from thehandle 690 and into theresin 680. Theextension 694 can have a smaller cross section than theattachment end 692 of thehandle 690. Theresin 680 can have a slot orrecess 682 that can correspond in size and shape to theextension 694. Therecess 682 can receive theextension 694 such that the extension and the recess mate together. - The
extension 694 can have a substantially zero-clearance fit within therecess 682. In one aspect, theextension 694 can form therecess 682 when theattachment end 692 of thehandle 690 is inserted into thesleeve 70 prior to curing of theresin 680 such that the resin flows around the extension. In this way, the extension can increase the surface area of theattachment end 692 of thehandle 690 with respect to flat or blunt end of the handle, and, thus, increase the adhesive connection between thehandle 690 and theresin 680. Additionally, theextension 694 andrecess 682 can provide a mechanical lock betweenhandle 690 and theresin 680 so as to reduce independent movement of thehandle 690 with respect to thebrush head 22. - It is a particular advantage that the
extension 694 strengthens the connection between thebrush head 22 and thehandle 690. It will be appreciated that adhesive and mechanical attachment between thehandle 690 and thebrush head 22 can be broken by repeated pressing of the brush against a surface. Similarly, corrosive effects by the chemicals of the coatings the brush is applying can weaken and cause failure in the connection between thebrush head 22 and theattachment end 692 of thehandle 690. When the connection between thebrush head 22 and handle 690 is weakened or broken, thesleeve 70 can keep the brush head and handle together, but the brush head can develop a slight rock or wiggle with respect to the handle. This movement between thebrush head 22 and thehandle 690 can result in inaccuracies and loss of precision in the application of the coating to the surface. Thus, advantageously, theextension 694 can increase the adhesive connection between thehandle 690 and theresin 680, and reduce independent movement of thehandle 690 with respect to thebrush head 22. - As illustrated in
FIG. 18 , a brush, indicated generally at 700, is shown in accordance with another embodiment of the present invention. Thebrush 700 can be similar in many respects to thebrush 600 described above and shown inFIG. 17 . Accordingly, thebrush 700 can have a plurality offilaments 20 forming abrush head 22, ahandle 790, asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 792 of thehandle 790, and aplug 50 with aconcave end 52 forming aspace 40 between thefilaments 20. - Additionally, the
attachment end 792 of thehandle 790 can have a slot orrecess 794 that can extend into theattachment end 792 of thehandle 790. Therecess 794 can have a smaller cross section than theattachment end 792 of thehandle 790. Theresin 780 can have anextension 782 that can correspond in size and shape to therecess 794 in the handle. Therecess 794 can receive theextension 782. - The
extension 782 can have a substantially zero-clearance fit within therecess 794. In one aspect, therecess 794 can form theextension 782 when theattachment end 792 of thehandle 790 is inserted into thesleeve 70 prior to curing of theresin 780 such that the resin flows into therecess 794. In this way, therecess 794 can increase the surface area of theattachment end 792 of thehandle 790, and, thus, increase the adhesive connection between thehandle 790 and theresin 780. Additionally, therecess 794 andextension 782 can provide a mechanical lock betweenhandle 790 and theresin 780 so as to reduce independent movement of thehandle 790 with respect to thebrush head 22. - As illustrated in
FIG. 19 , a brush, indicated generally at 800, is shown in accordance with another embodiment of the present invention. Thebrush 800 can be similar in many respects to thebrushes FIGS. 17-18 . Accordingly, thebrush 800 can have a plurality offilaments 20 forming abrush head 22, ahandle 890, asleeve 70 circumscribing theattachment end 26 of thebrush head 22 and theattachment end 892 of thehandle 890, and aplug 50 with aconcave end 52 forming aspace 40 between thefilaments 20. - Additionally, the
attachment end 892 of thehandle 890 can have anextension 894 that can extend away from thehandle 890 and into theresin 880. Theextension 894 can have a smaller cross section than theattachment end 892 of thehandle 890. Additionally, theextension 894 can have agroove 898 that can extend along a longitudinal length of theextension 894. Thegroove 898 can be of sufficient size and shape so as to allowresin 880 to fill the groove to further reduce independent movement of the handle with respect to the plurality of bristles. - Thus, the
resin 880 can have a slot orrecess 882 that can correspond in size and shape to theextension 894 and thegroove 898. Therecess 882 can receive theextension 894, and aportion 884 of theresin 880 can substantially fill thegroove 898. - The
extension 894 can have a substantially zero-clearance fit within therecess 882. In one aspect, theextension 894 can form therecess 882 when theattachment end 892 of thehandle 890 is inserted into thesleeve 70 prior to curing of theresin 880 such that the resin flows around theextension 894 and into thegroove 898. In this way, theextension 894 and groove 898 can increase the surface area of theattachment end 892 of thehandle 890, and, thus, increase the adhesive connection between thehandle 890 and theresin 880. Additionally, theextension 894,groove 898 andrecess 882 can provide a mechanical lock betweenhandle 890 and theresin 880 so as to reduce independent movement of thehandle 890 with respect to thebrush head 22. - The present invention also provides for a method for making a paint brush including placing a plurality of bristles inside a sleeve. A resin can be applied into the sleeve to contact the plurality of bristles. A handle can be inserted into the sleeve to contact the resin. An extension formed in one of the handle or the resin can be fitted into a recess formed in the other of the handle and the resin.
- The method can also include allowing the resin to at least partially cure before inserting the handle. Additional resin can then be applied into the sleeve to contact the at least partially cured resin. The handle can be inserted into the sleeve to contact the uncured and at least partially cured resin.
- It is to be understood that the above-referenced arrangements are only illustrative of the application for the principles of the present invention. Numerous modifications and alternative arrangements can be devised without departing from the spirit and scope of the present invention. While the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications can be made without departing from the principles and concepts of the invention as set forth herein.
