The present invention relates to paint brushes.
Paintbrushes have been used for many years to paint surfaces including the interior or exterior surfaces of a home, business, or other structure. Paintbrushes are typically comprised of a handle which the user holds with their hand and a brush head that contains the bristles that are used to retain and spread the paint.
Traditionally, paintbrushes are manufactured with a fixed bristle width, length, angle, and shape. Often, a painter needs to paint a surface that has an unusual shape, or a surface that has a smaller width than that of a standard paintbrush. The surface may also require bristles with an angled shape to allow for a better application of paint to the desired surface.
For example, paintbrushes with bristles that are cut at an angle are often used to make it easier to paint clean lines. They are also used to paint anything with grooves, such as cabinets, furniture, or paneled doors, or when a user is painting close to another surface, such as between window trim and walls.
Traditional paintbrushes do not have options for adjusting the width, length, angle, or shape of the paintbrush bristles' application surface to allow for a neat and controlled application of paint to the surface being painted. This requires the painter to maintain and utilize multiple paintbrushes of different sizes, widths, and bristle configurations. The painter then has to switch paintbrushes as needed which takes additional time and multiple paintbrushes.
Anthony (U.S. Pub. No. US 2017/0332775 A1) discloses a paintbrush having a plurality of individual bristle pack segments maintained within a brush slide body housing. The individual bristle pack segments are then able to slide, independently of one another, in and out of the brush slide body housing to create different lengths and shapes of the brush bristles.
Doorey (U.S. Pub. No. US 2017/0188692 A1) discloses an adjustable paintbrush wherein the bristles are contained within a rotatable ferrule within the paintbrush. This allows the painter to adjust the painting angle by adjusting the rotatable ferrule and utilizing a locking mechanism to lock the bristles and ferrule in place. However, this does not allow for the adjustability of the length or shape of the bristles.
While the aforementioned inventions may be suitable for the particular purpose they address, the inventor has determined that there remains a need for a paintbrush which allows the painter to adjust the application surface's shape and/or length with a single sliding mechanism.
One object of the present invention is to allow a painter to adjust the width, length, and/or shape of the bristles or brush head (collectively, “bristles”) of a paintbrush with a single sliding mechanism. The bristles and handle can be adjusted to create the proper bristle shape and brush handle length for painting in tight spaces, on specific textures, or in broad strokes, for example. Attachment members can also be used to attach a handle to the paintbrush. This further allows the attachment of paint roller heads and paint brushes with a variety of widths to the detachable handle.
To attain these objects, an adjustable bristle pack having a top end and a bottom end is situated within a brush body having an open end and a closed end. The brush body is configured to accommodate the bristle pack and a sliding mechanism between the bristle pack and the closed end of the brush body. The adjustable bristle pack is attachable to the sliding mechanism for example, with a latch or magnet. The sliding mechanism has a length, a knob portion, and a first end opposite the knob portion. The length of the sliding mechanism is such that the first end is contained within the brush body while the knob portion is outside the brush body.
The sliding mechanism is then moveable between a first and second position. This allows the bristles to be adjusted as they are attached to the sliding mechanism. The first position is wherein the adjustable bristle pack is contained substantially within the brush body. The second position is wherein the top end of the bristle pack is within the brush body and the bottom end of the adjustable bristle pack is within the brush body.
Finally, the brush body has a handle attachable at the closed end. The handle may also be a removable or detachable handle by way of a first attachment member on the closed end of the brush body and a second attachment member on the handle. The first and second attachment members are attachable to each other, making the handle removeable from the brush body. The attachment members can be a depressible button coupling, for example. The bristles (or brush) head may be biased toward
The present invention provides an adjustable paintbrush with a single sliding mechanism to move a brush head between extended and retracted positions.
Those of skill in the art will understand that various details of the invention may be changed without departing from the spirit and scope of the invention. Furthermore, the foregoing description is for illustration only, and not for the purpose of limitation, the invention being defined by the claims. For example, while the attachment members in the drawings are depressible buttons, the attachment members can be comprised of various shapes and materials including, but not limited to, buttons, magnets, and Velcro. Further, the material to be used for the handle may be any suitable material including, but not limited to, wood, plastic, metal, and silicone.
