Paint Brush Edging Tool
Paint brush edge guide tool for a brush handle, has a proximal attachment, a stabilization plate disposed adjacent the handle, and a first elevated plate rising above the stabilization plate. The elevated plate rises at an acute angle away from the 3-D brush plane, being twisted about an axial centerline of the plane. An elevated terminal plate extends beyond the first elevated plate and is twisted about the centerline. The terminal plate distal edge extends beyond the terminal edge of the 3-D brush plane and the terminal plate is disposed at an obtuse angle from the elevated plate such that the terminal plate edge extends longitudinally beyond the 3-D brush plane and lies substantially adjacent the facing region of the 3-D brush plane. The terminal plate is twisted about the centerline. The interface between the elevate plate and the terminal plate may be a flex joint.
The present invention relates to a patent brush tool which is used in connection with a paint brush and enables the user to easily cut in a painted edge between intersecting walls or intersecting walls and moldings.
BACKGROUND OF THE INVENTIONIt is well-known that cutting in an edge between two interfacing wall surfaces or between the interface between a wall and molding is difficult. A user typically dips his or her paint brush into the paint and attempts to paint a straight line along a considerable length, typically more than 2-3 feet (more than 1 m). During this activity, the edge of the brush may wobble thereby painting an edge that is not straight. The present invention solves this problem.
U.S. Pat. No. 3,210,791, an Edger Attachment for Paint Brushes, discloses an edger attachment that includes a shielding plate pivotally mounted on a paint brush for movements between an operative position for guiding the bristle end portions of the brush and an inoperative position away from the bristles of the brush.
U.S. Pat. No. 3,930,278, a Paintbrush and Guard Attachment for Edging, discloses a device for removable attachment to a paintbrush to assist in cutting-in one flat surface to another. It is formed of a flat metal sheet having a “foot” and a pair of bendable arms that can be bent to engage the opposite sides of the handle of a paintbrush, while the “foot” portion acts as a guide and shield against unintentional smearing.
U.S. Patent Published Application No. 2015/5223593, a Novel Paint Brush with Built In Edger, discloses a paint brush with a built in edger system that aims to control the application of paint and purportedly eliminates the need to use masking tape. The edger system is attached to the brush as a mechanical attachment. The edging device aims to prevent paint from going beyond the borders of the edging device.
U.S. Pat. No. 782,53, a Paint Brush, discloses a paint brush with an attachment in the form of a guard or shield. The shield is able to retract to expose the bristles of a brush and then readily extended to cover the brush, as needed.
U.S. Pat. No. 3,049,741, a Paint Brush Guide, discloses a paint brush guide to attach to a paint brush in order to guide the brush along a window casing or frame.
U.S. Pat. No. 3,341,879, a Paint Brush Edging Attachment, discloses another form of an edging attachment.

OBJECTS OF THE INVENTIONIt is an object of the invention to provide an edging tool that can be removably attached to a paint brush handle.
It is a further object of the present invention to provide an edging tool which permits the user to gather paint at the terminal end of the paint brush bristles without placing paint on the distal terminal edge of the edging tool.
It is another object of the invention to provide an edging tool that primarily has elevated shields or plates which extend outboard and away from the three dimensional bristle plane.
SUMMARY OF THE INVENTIONA paint brush tool adapted to be removably attached to a handle on a paint brush wherein the paint brush has a handle, a bristle box longitudinally and laterally extending from the handle and paint brush bristles extending both longitudinally outboard beyond the bristle box. The bristles, both longitudinally and laterally form a three dimensional (3-D) solid bristle brush plane. The tool includes a guide having a proximal attachment member attached to the handle. The guide has a stabilization plate adapted to be disposed substantially on and adjacent the handle proximal to the interface between the handle and the bristle box. The stabilization plate may extend to be adjacent the bristle box of the brush. In one embodiment, the guide has a first elevated plate above the stabilization plate at a rise rate of about 1 inch per foot. In another embodiment, the guide has a lateral, substantially perpendicular riser wall elevating a first elevated plate above the stabilization plate. The first elevated plate extends longitudinally beyond the stabilization plate, rises above the stabilization plate at an acute angle, about 15 degrees and is rotated in a roll manner about 30 degrees form the longitudinal centerline of the 3-D bristle brush plane. The first elevated plate is disposed at an acute angle away from the 3-D brush plane and extends at an angle away from and outboard of the 3-D brush plane. The tool includes a forward elevated terminal plate longitudinally extending beyond a distal edge of the first elevated plate. A distal edge of the terminal plate is adapted to extend longitudinally beyond a distal terminal edge of the 3-D brush plane. The forward terminal plate is disposed at an obtuse angle away from the first elevated plate such that the distal terminal plate edge both extends longitudinally beyond the 3-D brush plane and lies substantially adjacent a facing region of the 3-D brush plane. The first elevated plate and the forward terminal plate are adapted to be elevated over, spaced apart from and to cover the facing region of the 3-D brush plane. The first and second elevated plates are rotated at an acute angle about a longitudinal centerline of the 3-D brush plane away from the 3-D brush plane about 15-30 degrees from the 3-D plane.
As a result, the user is enabled to gather paint on the 3-D brush plane without placing paint on the forward terminal plate. Also, the distal edge of the forward terminal plate rides along the wall-to-wall corner (or wall-to-molding corner) thereby guiding the brush in a straight line.
Further features of the tool include a hinge at the interface of the first elevated plate and the forward terminal plate thereby permitting the terminal plate to flex towards and away from the first elevated plate as needed by the user. The tool has a stabilization plate, a riser, a first elevated plate and a terminal plate as a one-piece, integral structure. The hinge may be formed by a thin walled interface between the first elevated plate and the terminal plate. The thinner interface wall establishes a flexible joint between the first elevated plate and the terminal plate.
The paint tool may have a bristle box and the 3-D brush plane which respectively have a predetermined box length and width and a predetermined 3-D brush plane length and width. The first elevated plate and the terminal plate have lengths and widths which complement and cover the predetermined box length and width and predetermined 3-D brush plane length and width.
The 3-D brush plane has a terminal brush edge which may be angular with respect to a longitudinal aspect of the 3-D brush plate. In this case, the terminal plate has a distal terminal edge which is angular with respect to a longitudinal aspect of the terminal plate and which is complementary to the terminal brush edge.
Further objects and advantages of the present invention are found in the detailed description of the preferred embodiments when taken in conjunction with the drawings which are briefly described below.
The present invention relates to a paint brush tool and, more specifically, an edging tool which is removably mounted onto a paintbrush. Similar numerals designate similar items throughout the Figures.
Paint brush 10 includes a handle 12 and a handle transitional segment 12a leading longitudinally to bristle box 14. A plurality of paint brush bristles 17 (diagrammatically partly illustrated in the Figures) extend both longitudinally and laterally outboard beyond bristle box 14 as well as handle 12, 12a. Additionally, bristles 17 extend laterally from bristle box 30 to form a three-dimensional (3-D) solid bristle brush plane.
In
Paint tool 30 includes, at its proximal end, an attachment member which permits the tool to be removably attached to handle 12 of paint brush 10. Attachment systems are discussed later in
In one embodiment, the tool guide 30 includes a lateral, substantially perpendicular riser wall (not shown) which elevates a first elevated plate 40 above the stabilization plate 34 and the riser wall is perpendicular to the plane of plate 34. In another embodiment shown in the Figures, the first elevated plate 40 rises above the 3-D bristle plane 16 at an acute angle, about 15 degrees and rises above the stabilization plate 34 (plate 34 being adjacent to the brush handle and bristle box) and the first elevational plate is rotated about 30 degrees about the 3-D axial centerline 11a, 11b. In this manner, one lateral edge of plate 34 is nearer to the 3-D plane and the other lateral edge of plate 34 is farther away from the 3-D plane.
The first elevated plate 40 extends longitudinally beyond the distal end region of stabilization plate 34 and the proximal longitudinal region 38 of plate 40 is very near and sometimes adjacent the bristle brush box 14. The plate 40, with respect to
The elevated plate 40 is disposed at an acute angle away from 3-D brush plane 16 and extends at an angle away from and outboard of 3-D brush plane 16. This acute angle is shown as angle 41 in
The edge guide 30 includes a forward elevated terminal plate 44 which extends beyond the distal interface edge 42 of elevated plate 40. The elevated terminal plate 44 has a distal terminal edge or end 46 which extends longitudinally beyond distal terminal edge 18 of 3-D brush plane 16.
The forward terminal plate 44 is disposed at an obtuse angle away from the elevated plate 40 such that the distal terminal plate 44 and the edge 46 extends longitudinally beyond the 3-D brush plane 16 and the edge 46 lies substantially adjacent a facing region 19 of 3-D brush plane 16. As shown in
The forward plate has a terminal edge 46 (see
The elevated plate 40 and the terminal plate 44 are adapted to be elevated over and spaced apart from and cover the facing region 19 of the 3-D brush plane 16 and further are rotated about 15-30 degrees with respect to the axial centerline 11a, 11b. In this manner, a user can gather paint on the 3-D brush plane 16 and more specifically on bristles 17 without placing paint on the forward terminal plate 16 and on edge 46.
The lateral span 51 of tool guide 30 is greater than the lateral span 23 of the 3-D brush plane 16. In this manner elevated plate 40 and terminal plate 44 have complementary lateral and longitudinal dimensions which cover all the bristles. By covering 3D plane face 19, paint on bristles 17 do not strike any wall segment that terminal edge 46 of terminal plate 44 strikes. The terminal edge 46 forces bristle end 18 away from the wall striking terminal edge 46.
The bristles are covered a longitudinal distance 21a with the use of plates 40, 44 having a having a brush coverage distance 57. Further, plates 40, 44 are elevated above and both laterally and longitudinally cover the bristle box 14 and 3D brush plane 16 as shown by the combination of longitudinal distances 55, 57 and lateral distance 51. Although
The edging guide tool 30 may have a thin walled interface 42 between elevated plate 40 and terminal plate 44 which interface has thinner wall thickness than the thickness of plate 40 and plate 44. By thinning wall interface 42, this provides an additional flex joint, permitting flexing of the guide end 44, 46, with respect to plate 40. This flex joint 42 is noted by the double headed flex arrow 31 in
In one embodiment, the stabilization plate 34, riser 36, elevated plate 40 and terminal plate 44 are all one piece, as an integral structure. Preferably, guide structure 30 is made of plastic.
The guide edging tool 30 can be attached with many different types of attachment mechanisms, systems or members to handle 12.
The claims appended hereto are meant to cover modifications and changes within the scope and spirit of the present invention.
