Description
Background of the Invention
This invention relates in general to paint applicators and particularly to a roller applicator that is suitable for painting wrought iron railing.
The right tool for the job achieves efficiency and superior results, and nowhere is this principle more applicable than in painting. One painting job that can be particularly tedious, time consuming, and likely to frustrate a painter, is the job of painting railing such as the wrought iron railing that adorns many of our homes. This job involves painting the many relatively narrow surfaces of closely spaced rails in a repetitive sequence of carefully applied strokes, and so a specially designed paint applicator is called for. The right paint applicator would reduce the time and concentration otherwise required, and although many types and kinds of paint applicators exist, none are quite the right tool for painting wrought iron railing.
A typical section of wrought iron railing consists of a series of spaced apart rails extending perpendicularly between generally parallel top and bottom rails. Each of these rails may employ a variety of shapes, generally rectangular shapes and serpentine shapes being common. Each of these different shapes produces it own unique and attractive railing design, but at the same time it results in a great number of relatively narrow and closely spaced surfaces to which paint must be applied. Painting the railing involves applying paint to each one of these surfaces, and this requires a series of carefully applied, repetitive strokes that expend time and concentration.
Spray painting has been used in the past in an attempt to overcome this problem, but this has often had undesired results. The typical wrought iron railing installation is in close proximity to other objects such as buildings and shrubbery, and spray painting risks undesired painting of these nearby objects. Either that or the objects must be adequately masked with drop cloths or old newspapers. Consequently, it is desirable to have a paint applicator that reduces this risk and eliminates the related requirement of masking nearby objects.
In addition to spray painting, small conventional paint brushes have been used in the past in an attempt to simplify this type of painting job, but this does not significantly reduce the number of strokes, skill, or concentration required. The opposite approach, using an excessively large conventional paint brush and more paint in a slap-it-on approach, is in some respects less tedious, but the results are correspondingly less professional. Consequently, it is desirable to have a paint applicator that reduces the number of strokes, skill, and concentration required in painting wrought iron railing while still enabling a painter to achieve quality results.
Although roller paint applicators exist for some painting jobs, none of these are suited to the relatively detailed work of painting wrought iron railing. Existing roller applicators are designed for painting long flat surfaces in correspondingly long flat strokes. Some require two-handed operation, and others are totally unsuited for railing having a serpentine shape. Thus, it is desirable to have a paint applicator that can be used conveniently with one hand, and that is suitable for painting the twisted shape of serpentine railing.
Summary of the Invention
Therefore, it is an object of this invention to provide a new and improved paint applicator with the desired attributes for painting railing such as wrought iron railing, and it is an object to provide a roller paint applicator that is conveniently operable with one hand.
The above and other objects of the invention are realized by a device comprising a pair of elongated prongs to which a pair of rollers are attached. Each prong has a handle end and a roller end, with the handle ends being interconnected and each one of the rollers being rotatably mounted on the roller end of a corresponding one of the prongs. Spring-biasing components are provided both for spring biasing the prongs in side-by-side relation with the rollers slightly spaced apart, and for enabling the rollers to be flexed together against a section of railing by manually squeezing the prongs together.
One embodiment employs a V-shaped spring handle member of unitary wire construction that can be grasped and squeezed with one hand to flex the rollers together. The rollers are composed of a soft spongy material that deforms when flexed against a section of railing, thereby encircling the railing so that paint is applied simultaneously all the way around.

Detailed Description
Referring now to the drawings, and particularly to FIGS. 1 and 2, there is shown a paint applicator constructed in accordance with the invention. It is referred to generally by reference numeral 10 and shown in FIG. 1 in a painting position against railing 20.
Applicator 10 includes a first handle member, prong 30, extending between handle end 31 and roller end 31A. The prong 30 includes a handle portion 30A extending from handle end 31 to bend 33, and a bent or offset portion 32 extending from bend 33 to roller end 31A that offsets roller alignment. Applicator 10 includes a second handle member, prong 40, extending between handle end 41 and roller end 41A. As illustrated, the prong 40 extends outwardly from the handle ends with prong 30 generally in a common plane and in a common direction (the gripping axis), and it includes a handle portion 40A extending from handle end 41 to bend 43, and a corresponding bent or offset portion 42 extending from bend 43 to roller end 41A.
In the illustrated embodiment, these prongs are composed of three-sixteenths inch spring wire, and they are each about one foot long. Other generally rigid handle members may be employed. The bent portions offset the rollers so that they are not in line with the longitudinal axis of the corresponding prong and, hence, out of line with a user's grip. This results is a more convenient positioning of the rollers relative to the user's hand when the paint applicator is stroked back and forth on a section of railing.
Rotatably mounted rear the roller end of each offset portion of the prongs is a roller 50. Each of the rollers is held in place with bearing collars 51 and push-on caps 52, both of which employ a force fit to hold them in place. The illustrated rollers are one and one-half inch diameter foam rubber members that are cyclindrically shaped. Other material can be used so long as the rollers can retain enough paint to enable transfer of paint from a container to the railing being painted, and so long as they can deform sufficiently to partially encircle the railing.
The handle ends of the prongs, handle ends 31 and 41, are movably connected together by suitable means. The illustrated embodiment employs a midpotion bend in the spring wire that extends from one handle end to the other to define the illustrated helically-shaped loop 60. This loop serves also as spring biasing means for maintaining the prongs in diverging positions (as shown in FIG. 2) such that the rollers are slightly spaced apart in side-by-side relation. This position allows the rollers to be placed on opposing sides of railing 20 in position for applying paint to the railing.
The spring biasing is such as to enable the rollers to be flexed together against the railing by manually squeezing the prongs together. Thus, by grasping the prongs and squeezing them together, the rollers flex together as indicated by arrow 70 (FIG. 2).
Other means of connecting the handle ends together, such as a hinge, may be employed within the inventive concepts herein disclosed, along with other means of spring biasing the prongs, such as a spring. The unitary wire construction of the illustrated embodiment is especially useful in combining these functions in loop 60.
FIG. 3 illustrates the manner in which the rollers encircle the railing being painted. The illustrated railing is generally square in cross-section, thereby defining four surfaces 21-24. When flexed together, the rollers come in contact with the railing and deform so that one of the rollers contacts both surfaces 21 and 22 while the other one of the rollers contacts both surfaces 23 and 24. Thus, paint can be applied all the way around the periphery of the railing by rolling the paint applicator of this invention back and forth in a few easy strokes.
This feature also facilitates painting of more complex shapes, such as serpentine railing. The rollers deform to encircle the railing as the applicator is moved back and forth while being squeezed against the railing. Thus, the skill and concentration normally required for carefully-applied repetitive strokes are avoided.
Further details of the rollers are shown in FIG. 4. Bushing 53 is a plastic tube that extends axially down the center of roller 50. Other suitable bushings may be employed to enable roller 50 to rotate on the roller end of the prong. Bearing collar 51 and push-on cap 52 bear against the bushing to retain the roller in position on the end of the prong.
In operation, the paint applicator is grasped with one hand and either dipped or rolled in paint that is to be applied to the railing. The rollers are then placed on opposite sides of a section of railing, with the prongs being manually squeezed so that the rollers flex together against the section of railing. Then, with a series of back-and-forth strokes, the paint is rolled onto the railing. Just enough pressure is applied to the prongs to deform the rollers around the railing so that paint is simultaneously applied all the way around. The grip on the prongs is then relaxed, the applicator is withdrawn from the railing, and the process is repeated.
Thus, the paint applicator of this invention enables one-handed operation that avoids the careful repetitive strokes and related skill and concentration otherwise required in painting wrought iron railing.
The paint applicator comprises a pair of elongated prongs and a pair of rollers. Each prong has a roller end on which one of the rollers is rotatably mounted, and a handle end that is movably connected to the handle end of the other prong. Spring-biasing means position the prongs in side-by-side relation with the rollers slightly spaced apart, while enabling the rollers to be flexed together against a selected section of railing by manually squeezing the prongs together.
Prongs 30 and 40 are connected by loop 60 in the illustrated V-shaped spring handle member. This unitary construction may be replaced with separate prongs that are suitably connected together and spring-biased. Other modifications may be made within the inventive concepts herein disclosed while retaining the essential features that make this roller paint applicator the right tool for the job.
As various changes may be made in the form, construction, and arrangement of the procedures and parts described herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, all matter herein is to be interpreted as illustrative and not in any limiting sense.
