Description
- This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 60/395,061, filed May 10, 2010 and entitled PAINT APPLICATION SYSTEM, the entirety of which is herein incorporated by reference.
- The invention relates to painting tools, including paintbrushes, paint rollers and other painting-related implements having detachable handles.
- Painting, in particular, residential painting, typically involves the use of a variety of tools, such as paintbrushes and rollers, paint scrapers, putty knives and razor blades. The conventional tool has both a handle and a tool head. Usually, the head is permanently attached to the body such that the head cannot be separated from the body. A typical head features a paint applicator, such as a brush formed of bristles, a sponge, or a roller. Often, bristles are permanently attached to the handle using a ferrule, which is a metallic clamp that surrounds a lower portion of the bristles and an upper portion of the handle to bind the bristles to the handle.

The conventional tool has both a handle and a tool head. Usually, the head is permanently attached to the body such that the head cannot be separated from the body. A typical head features a paint applicator, such as a brush formed of bristles, a sponge, or a roller. Often, bristles are permanently attached to the handle using a ferrule, which is a metallic clamp that surrounds a lower portion of the bristles and an upper portion of the handle to bind the bristles to the handle.
- Tools featuring different heads may be useful for different purposes. Therefore, a user normally purchases and maintains separate paintbrushes having heads of various sizes, shapes and materials. The same can be said for paint rollers, paint scrapers and putty knives. The result can require a significant investment in tools. These tools are typically used for a limited number of applications, in most cases just once, and then discarded, requiring the additional costs of replacing them for subsequent projects.
- Not only is there a significant impact on the consumer in the cost of acquiring and replacing such tools, but there is also a significant impact on the environment by the consumption of materials for producing the tools and by the subsequent and continual increase in waste from discarding the tools. Currently, the primary material for the handles of these types of tools, especially paintbrushes, is wood. It has long been known that the destruction of the world's forests to feed the ever-increasing demands of consumerism is environmentally unsound. Although there have been some movement toward the use of sustainable and/or environmentally friendly materials in many products, the market still primarily offers basic painting implements and related tools with handles made from wood.
- There are many patents and published patent applications out there showing variations on paintbrushes having detachable handles, each one more complicated than the last. There are also a number of publications showing other hand tools having detachable handles. Most of these are offered to provide a versatile tool system wherein a single handle can be utilized with multiple different tool heads, giving the user a large variety of options without having to buy a significant number of bulky and costly individual tools.
- In addition, many of the paintbrush-related patents are directed to variations that provide handles that are: adjustable in angle with respect to the head; capable of catching excess paint from the head to keep the painter's hand clean or prevent drips; quickly interchangeable with other heads to allow for easy changes in color, particular location or surface; and/or capable of attaching to the head without the use of a ferrule, so that the paint or other medium can be cleaned more thoroughly from the head. Although many of these offer advantages in one or more particular aspects of painting implements, all of them still have disadvantages in other important features of the devices.
- The present invention is directed to a painting tool system having a reusable handle, the handle having first and second ends and a body interposed between the two ends. The first end of the handle including an opening adapted to receive a shaft, with the handle body configured to be gripped in a user's hand. The painting tool system also including a painting tool attachment adapted to detachably couple to the handle. The tool attachment having a first end configured to perform a function of the painting tool and a second end including a protruding shaft adapted to be received within the opening in the handle.

ring 220 is positioned in aninset 203 in thehandle body 201 in a tight-fit relationship, such that the retainingring 220 is retained in theinset 203 during normal use of thepushpin 210. As such, the retainingring 220 does not emerge from theinset 203 until a user inserts an item of suitable length and diameter into the throughhole 202 to push against thesecond end 212 of thepushpin 210 with sufficient force to dislodge the retainingring 220 from theinset 203. At that time, both the retainingring 220 and thepushpin 210 are dislodged from thehandle 200. - The retaining
ring 220 has anouter diameter 221 that is larger than the diameter of the throughhole 202 and aninner diameter 222 that is only slightly larger than theshaft portion 213. As a result, thepushpin 210 is free to slide within the throughhole 202 between theuser interface member 216 and thestep 217 between theshaft portion 213 and thebody 214. With the inclusion of thespring 218, however, thepushpin 210 may be slid into the throughhole 202 by pushing on theuser interface member 216, but thepushpin 210 is automatically returned to its initial position, as shown in the detail view ofFIG. 26 , by the force of thespring 218 once the pushing force is removed from theuser interface member 216. - The
body 214 of thepushpin 210 includes aneck area 215 formed as a radial groove about the axis of thehandle lock 210. Theneck area 215 is positioned on thepushpin 210 to be offset from theopening 204 when thepushpin 210 is in its initial position. Pushing thepushpin 210 into thehandle body 201 against the force of thespring 218 causes theneck area 215 to align with theopening 204, thereby allowing insertion or removal of theshaft 90 of apainting tool attachment 80. Once theshaft 90 is received within theopening 204, thepushpin 210 is released and returned to its initial position. As a result, thesecond end 212 of thebody 214 becomes positioned within theneck area 94 of theshaft 90. Thepainting tool attachment 80 is then locked in place until thepushpin 210 is once again operated by pushing it into thehandle body 201. - While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein.
