Description:
FIELD OF INVENTION 
     This invention relates to the field of devices for paint application and more particularly to the field of paint brushes handles with interchangeable brush heads and rollers. 
     BACKGROUND OF THE INVENTION 
     In order to use a paint brush one has to move his wrist as he moves up and down or from side to side with the brush. If a person is employed as a painter he has to make this motion day in and day out. This will ultimately lead to the painter getting a repetitive stress injury or carpal tunnel syndrome and painting will cause him a great deal of pain. 
     Also, for older painters who have arthritis within their wrists, painting is painful. The inventor has designed a brush will greatly reduce these problems. Thus, the first objective of this invention is to create a brush which an individual can use without the normal up and down movement or side to side movement of the wrist. The feature that enables the inventor&#39;s brush to be used without movement of the wrist is that the inventor has moved the handle so that the handle would be ninety degrees or perpendicular to the brush head. This also enables the painter to grab the brush in a normal grip. He can now use the brush without movement of his wrist. The applicant has further made the brush handle slightly curved and shaped so that an individual can hold the brush in a normal grip. Another problem of the brushes presently out on the market is that the brush head wears out far earlier than the handle of the brush. The brush head can wear out for several reasons. The first being that the brush was not properly cared for thus the paint, varnish or shellac has dried within the brush making it unusable. Brush heads also wear out from normal use. In both of these cases the brush head will wear out long before the handle wears out. 
     Thus, one of the objectives of this invention is to create a method of removing a brush head from the handle and replacing it with another. Applicant has developed a method for interchangeable brush heads so if the first one wears the brush head can be replaced with another. This also enables the individual to place brush heads of different sizes on the brush. Thus, one handle can be used for a one inch brush as well as a three inch brush head. Further, being able to take the brush head off the handle enables the individual to more easily clean the brush head. Due to the smaller size brush head it allows for a smaller storage area for the brush. It also makes the storage must easier. The brush heads are small enough that they can easily be placed in a small plastic bag. 
     The handle can also be used for a roller. Thus, painter can place either the brush head or a roller on the handle. The perpendicular handle enables the painter to use the roller with a different motion then the roller presently out on the market. It has been applicant&#39;s experience that painters who use the roller with the perpendicular handle preferred it to a regular roller with a handle. 
     SUMMARY OF THE INVENTION 
     Applicant has developed a whole new painting system. The painting system centers around two different handles. The first handle is a straight handle and is similar to the handles of paint brushes on the market. This handle differs from paint brushes on the market by the fact that it will hold interchangeable brushes. This product is a paint brush with interchangeable paintbrush heads. The product has two components, the straight handle and the different size paintbrush heads. The straight handle has a dove tail groove on its top and the paint brush head has a dove tail on its bottom. The dovetail of the paint brush head fits within the dovetail groove of the straight handle. The friction between the dovetail groove and the dovetail holds the paint brush head upon the straight handle solidly. Not only are the heads interchangeable but you can place more than one paintbrush head on the straight handle. Thus if the individual did not have a 3 inch paintbrush but had 1 inch brush heads and 2 inch brush heads he could place the 1 inch brush head and a 2 inch brush head on his straight handle and form a 3 inch brush head. The applicant has also fattened the handle for better grip. The second handle, the perpendicular handle, is entirely different from regular paintbrush handles. The object of this second handle is to enable an individual to paint without bending one&#39;s wrist. In this handle the paint brush bristles are perpendicular to one&#39;s grip. The painting system for perpendicular handle has two components as the straight handle system, the perpendicular handle and the brush head. The brush head for the perpendicular handles are exactly the same as the brush heads for the straight handle and these brush heads can be interchangeable upon either handle. As in the previous embodiment the brush head has a dove tail on its bottom and the handle has a dove tail groove on its side. The dovetail on the bottom of the brush head fits within the dovetail groove on the perpendicular handle and the brush head is held in place by friction within the dovetail groove. From the dovetail groove the perpendicular handle begins to extend downward. This handle, however extends downward from the side of the dovetail for only a short distance. It then extends parallel to the dovetail groove section. This creates an open area under the dove tail groove section for the individual to grip the handle. This handle is also fatter than the normal handle for easier grip. 
     The roller is similar to the rollers presently on the market. However, the handle has been removed and replaced with a dovetail. This dove tail fits within the dovetail groove on the perpendicular handle. At the very bottom of the dovetail is a threaded extension. The threaded extension is designed to allow a pole with threads on its top to be threaded within the threaded extension to extend the handle of the roller for painting in high areas and ceilings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       FIG. 1  is a front view of the perpendicular handle  10 .  FIG. 2  is a front view of the perpendicular handle  10  with the brush head  18  attached.  FIG. 3  shows the side view of the perpendicular handle  10 .  FIGS. 4 and 4A  is the top view of perpendicular handle  10 . At the top of the perpendicular handle  10  is a dovetail groove  28 . The dovetail groove  28  runs along the length of the top of the perpendicular handle  10  as shown in  FIGS. 4 and 4A . The perpendicular handle  10  extends downward from the dovetail groove  28 . The perpendicular handle  10  extends downward from the side of a dovetail groove section  16  for a short distance. Than the bottom section  12  of the perpendicular handle  10  extends nearly parallel to the dovetail groove  28 . The bottom section  12  leaves an open area between it and the dove tail grove section  16 . The bottom section  12  extends past the end of the dovetail grove  28  and nearly parallel to the dovetail grove  28 . 
     To grip the perpendicular handle  10  one places his fingers between the bottom section  12  of the perpendicular handle  10  and the dovetail groove section  16  and then wraps one&#39;s fingers around the bottom section  12  of the perpendicular handle  10 . The bottom section  12  of the perpendicular handle  10  is larger than a normal paintbrush handle. This enables the individual using the perpendicular handle  10  to grip the perpendicular handle  10  more easily. As one can see from  FIG. 2  the bottom section  12  of the perpendicular handle  10  is not quite perpendicular to the bristles  14  of brush section  18 . In the preferred embodiment the angle is slightly less than 90°. The bottom section  12  of the perpendicular handle  10  can vary from being perpendicular with the bristles  14  of brush section  18  by as much as 45°. However applicant has found that painters prefer the angle of bottom section  12  of perpendicular handle  10  being slightly less than 90° from the alignment of the bristles  14 . 
       FIG. 3  is the side view of the perpendicular handle  10 .  FIG. 3  shows the shape of the dove tail groove  28 . The dovetail groove  28  is a dovetail with its sides slanting outward. 
       FIG. 5  is a side view of the brush head  18 .  FIG. 5A  is an end view of the brush head  18 . The end view  FIG. 5A  shows that the bottom of the brush head  18  has a dove tail extension  30 . This dove tail extension  30  fits within the dove tail groove  28  at the top of the perpendicular handle  10 . Dovetail extension  30  and dovetail groove  28  are designed to fit together with a friction fit. Dovetail extension  30  and dovetail groove  28  are designed with a friction fit so that the brush head  18  will not move on perpendicular handle  10  without substantial force. In the preferred embodiment the perpendicular handle  10  and the dovetail extension  30  of brush head  18  are made of plastic. The plastic is picked from a group of plastics that create a secure friction fit. 
     Another embodiment of the perpendicular handle  10  and the brush head  18  are shown in  FIGS. 5B and 5C . In this embodiment perpendicular handle  10  and brush head  18  are made exactly as the previous embodiment except that on the dovetail extension  30  on brush head  18  a set of bumps  32  are placed. These bumps  32  correspond to a set of grooves  34  placed on the bottom of the dove tail groove  28  of perpendicular handle  10  shown in  FIG. 4A . When the dovetail extension  30  is placed within dovetail groove  28  the bumps  32  on the dovetail extension  30  fit within the grooves  34  on the dovetail groove  28 . 
       FIGS. 6A, 6B, 6C, 6D, and 6E  show other embodiments of the invention. In these embodiments the perpendicular handle  10  holds many different sizes of brush heads  18  and  20 . Also as pointed out by  FIGS. 6C, 6D, and 6E  the perpendicular handle  10  can hold more than one brush head  18  and  20 . The brush heads  18  and  20  are interchangeable. Brush head  18  or  20  in  FIGS. 6A, 6B, 6C, 6D, and 6E  can be removed from the perpendicular handle  10  and be replaced with another brush head  18  or  20 . In this embodiment there are two brush heads  18  and  20  in  FIGS. 6C, 6D, and 6E  placed upon the perpendicular handle  10 . In the preferred embodiment perpendicular handle  10  is approximately 3 to 4 inches wide. It can hold two or more brush heads  18  and  20 . The brush heads  18  or  20  can vary in width. 
       FIG. 7  shows an attachment roller  100  for perpendicular handle  10 . The attachment roller  100  looks similar to a roller that is presently on the market. As the roller presently on the market the attachment roller  100  has at its top a cage  1102  on which the roller&#39;s  100  painting surface is placed. The cage  102  is designed to rotate around a cylindrical bar  104 . The cylindrical bar  104  passes through the center of the cage  102  and upon exiting the cage bends downward. The cylindrical bar  104  then bends back towards the handle attachment  106 . In rollers presently on the market the cylindrical bar would then bend back towards a straight handle. In the present invention the cylindrical bar  102  bends back towards the handle attachment  106 . In other words applicants invention differs from the roller presently on the market in that the handle of the roller presently a on the market has been replaced by the handle attachment  106  of applicant&#39;s patent. 
     The handle attachment  106  is shown in  FIG. 8 . The handle attachment  106  is comprised of the attachment block  108  that attaches the handle attachment  106  to the cylindrical bar  102  and a dove tail extension  110 . Extending from the side of the handle attachment block  108  is the dovetail extension  110 . To use the attachment roller  100  the dovetail extension  110  of the handle attachment  106  is placed within the dove tail groove  28  of the perpendicular handle  10 . 
     At the bottom of the handle attachment  106  a threaded extension  112  is attached. This threaded extension  112  is threaded and is designed to allow a pole to be threaded within. When the pole is threaded within the threaded extension  112  the roller  1100  can be used to paint ceilings and high areas. 
       FIG. 9  shows another embodiment of the invention.  FIG. 9  looks exactly as  FIG. 7  with the perpendicular handle  10  attached except the handle in  FIG. 9  is not detachable. In  FIG. 9  the roller  150  is exactly the same as the roller in  FIG. 7 . As in the previous embodiment the roller  150  has at its top a cage  152  on which the roller&#39;s  150  paint surface is placed. The cage  152  is designed to rotate around a cylindrical bar  154 . The cylindrical bar  154  passes through the center of the cage  152  and upon exiting the cage turns downward. The cylindrical bar  154  then bends back towards the perpendicular roller handle  156 . Unlike the previous embodiment the cylindrical bar  154  does not attach to the handle attachment  106 , it attaches directly to the perpendicular roller handle  156 . Perpendicular roller handle  156  is almost exactly like perpendicular handle  10 . The only difference is that the cylindrical bar  154  attaches permanently to perpendicular roller handle  156  on the side of perpendicular handle  156 . In perpendicular roller handle  156  the dovetail groove section  16  of perpendicular handle  10  has been replaced by the attaching cylindrical bar section  158 . On the side of perpendicular roller handle  156  in place of the dovetail groove  28  of perpendicular handle  10  is the attaching bar section  158 . The perpendicular roller handle  156  extends away from the attaching bar section  158 . The perpendicular roller handle  156  extends away from the attaching bar section  158  for a short distance. Then the perpendicular roller handle&#39;s  156  bottom section  160  extends parallel to the attaching bar section  158 . To use the roller one grips the bottom section  160  of the perpendicular roller handle  156  by placing one&#39;s fingers between the bottom section  160  of the perpendicular handle  156  and the attaching bar section  158 . This enables the individual using the perpendicular roller handle  156  to grip the perpendicular roller handle  156  more easily. 
     Attaching to the bottom of the attaching cylindrical bar section  158  is a threaded extension  162 . This threaded extension  162  is threaded and is designed to allow a pole to be threaded within. When the pole is threaded within the threaded extension  162  the roller  150  can be used to paint ceilings and high areas. 
     Applicant has found that painters prefer his perpendicular roller handle to the rollers that are now out on the market. Many have told him that it places the roller in an easier position to paint a wall. 
       FIGS. 10, 10A, 10B, 10C, 10D, and 10E , show another embodiment of the invention. In  FIGS. 10, 10A, 10B, 10C, 10D, and 10E , the straight handle  40  looks very similar to the paint brushes now on the market.  FIG. 10E  shows the front view of the straight handle  40 .  FIG. 10E  show the straight handle  40  griping portion  42  is larger than a normal paint brush handle.  FIG. 10  shows the griping portion  42  of the straight handle is in line with the strands  44  of the brush head  48 . Straight handle  40  and a brush head  48  make up the paint brush. Within straight handle  40  one or more brush heads  48  that can be placed. In  FIGS. 10, 10A, 10B, 10C, and 10D  the brush head  48  is interchangeable with other brush heads  48 . In this embodiment the straight handle  40  and the brush head  48  attach together just as in the previous embodiment. The brush heads  48  for this embodiment are designed similarly to the brush heads  18  for the previous embodiment. Brush heads  18  and  48  could be interchangeable. The width of the straight handle  42  can be made large enough so that more than one brush head could actually be placed on the straight handle  42 . Thus, an individual could use, say two, two inch brush heads  48  if the straight handle  42  width was four inches, or he could use one four inch brush head  48 . 
     The top portion  46  of straight handle  40  contains a dove tail grove  58 . The shape of the dove tail groove  58  can be easily seen in  FIG. 12 , a side view of the straight handle  40 . The sides of the dove tail groove  58  are slanted outward. This dove tail groove  58  is designed to allow the paint brush head  48  shown in  FIGS. 13 and 13A  to fit within. 
       FIGS. 11 and 11A  shows a top view of two different embodiments of the straight handle  40 . In  FIGS. 11 and 11A  one sees that the straight handle  42  has a dove tail groove  58  at op. 
       FIG. 13  is a side view of the brush head  48 .  FIG. 13A  is an end view of the brush head  48 . The end view  FIG. 13A  shows that the bottom of the brush head  48  has a dove tail extension  60 . This dove tail extension  60  fits within the dove tail groove  58  at the top of the straight handle  42  show in  FIG. 11 . Dovetail extension  60  and dovetail groove  58  are designed to fit together with a friction fit. Dovetail extension  60  and dovetail groove  58  are designed with a friction fit so that the brush head  48  will not move on straight handle  42  without substantial force. In the preferred embodiment the straight handle  42  and the dovetail extension  60  of brush head  48  are made of plastic. The plastic is picked from a group of plastics that create a secure friction fit. 
     Another embodiment of the invention is the straight handle  42  shown in  FIG. 11A  and the brush head  48  are shown in  FIGS. 13B and 13C . In this embodiment straight handle  42  and brush head  48  are made exactly as the previous embodiment except that on the dovetail extension  60  on brush head  48  a set of bumps  32  are placed. These bumps  32  correspond to a set of grooves  34  placed on the bottom of the dove tail groove  58  of straight handle  42  shown in  FIG. 11A . When the dovetail extension  60  is placed within dovetail groove  58  the bumps  32  on the dovetail extension  60  fit within the grooves  34  on the dovetail groove  58 . 
       FIGS. 14 and 14A  show a device  200  that can be attached to perpendicular handle  10  or straight handle  42 . The device  200  is an attachment to perpendicular handle  10  and straight handle  42  that enables the brush heads  18  and  48  or the attachment rollers  100  to be attached to the perpendicular handle  10  and the straight handle  42  at a 90° angle. Device  200  comprises a dovetail groove  202  attached to a dove tail extension  204 . The dovetail groove  202  is perpendicular to the dovetail extension  204 . The dovetail extension  204  is designed to fit within the dovetail groove  28  of the perpendicular handle  10  and the dovetail groove  58  of the straight handle  42 . When device  200  is placed on either the perpendicular handle  10  or the straight handle a brush head  18  or  48  or an attachment roller  100  can be placed within the dovetail groove  202  and will be oriented perpendicular to the straight handle  42  and the perpendicular handle  10 .
