Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates generally to coating application devices. More particularly, the invention pertains to a floor coating application device for applying protective, functional or decorative coatings to planar surfaces, such as hardwood floors, concrete floors, and the like.




2. State of the Art




Various materials are used as protective, functional or decorative coatings for planar surfaces. Many coating materials are applied to surfaces in a liquid state, later drying to form the desired coating. It is not uncommon to apply more than one layer of a coating to a particular surface in order to increase the thickness of the overall coating and thereby improve the resiliency, durability, and longevity of the surface. The coating material is typically applied to the surface and then uniformly distributed over the surface and smoothed by an application device.




The thickness of each layer of coating material distributed over the surface varies with the type of coating material used and the amount of pressure used to apply the coating material. Because of the dependency of the coating thickness on the characteristics of the coating material, the manufactures of coating materials provide guidelines which detail the amount of coating material necessary to cover a given surface area. If the guidelines are followed, a near perfect coating thickness should be achieved. However, there are a few factors that make it difficult to achieve such a perfect coating.




The liquid state of coating materials makes it difficult to evenly spread the coating over a given surface area. The thickness of the wet coating layer often depends upon the amount of force used to spread the coating over a surface. The force originates from the application device which is typically controlled by a human operator. Many of the individuals practicing the art of coating floors have developed the skill required to judge how much force must be applied to an application device to achieve a desired coating thickness. Additionally, the speed at which the coating is spread over the surface by an operator can also make a difference in the coating thickness. Although a person spreading the coating layer may become fairly proficient in laying consistent coatings, those who are inexperienced or who are laying a new type of coating are often unable to maintain the uniformity desired in the coating thickness. Because of these human variables, the wet thickness of the coating will often vary. As the coating then dries, the thickness of the coating layer decreases and all of the imperfections in the wet thickness are magnified.




The ideal finished surface is one having multiple coating layers, dried to a uniform thickness, with as few flaws or irregularities as possible. Just as flaws and irregularities are caused by the inconsistent force and speed used to spread the coating layers, such things as the shedding of particles from the application device onto the coating layer, or particulate matter settling on the coating layers during the drying process or air bubbles forming in the liquid coating, may also cause flaws and imperfections in the coating surface. Because the coating layers are typically thin, such flaws and variances are compounded with each additional layer of coating material. To avoid such problems, application devices have been developed which decrease the amount of imperfections that occur in coating layers and aid in the application of uniform, thin layers of coating material to planar surfaces.




Typically, when an application device is used to apply a coating material to a planar surface a portion of the coating material is first applied to the surface and the application device is used to evenly spread the coating over the surface. This is accomplished by pushing or pulling the application device over the surface area upon which a coating material has been deposited. As the leading edge of the application device contacts the liquid coating material, the coating material is displaced across the edge of the application device. As the application device is pushed or pulled over the surface, a layer of coating material is deposited between the application device and the surface being coated. Occasionally, a mechanical device is used to push or pull the application device over the surface and thereby spread the coating material.




As coating material builds up on the application device the excess coating material is squeezed out of the applicator. This is accomplished by tapping, knocking, slapping, or pressing the application device against a hard surface to force the excess coating out of the applicator material. After the completion of a coating layer the applicator must be cleaned if it is to be used again. The applicator is cleaned by immersing the entire piece of material in a solvent. The applicator may then be reattached to the application device and the process of coating a surface may begin again.




There are a number of different types of floor coating application devices currently being used to apply coatings to planar surfaces such as hardwood and cement floors. One such application device consists of a body piece, an applicator and a handle used to guide the device. The body of the device is essentially a rectangular block made of a rigid material. The body typically has a length of approximately eighteen inches, a width of four to six inches and a thickness sufficient to maintain the rigidity of the body. These dimensions create two opposing sides with large surface areas. The body acts as a rigid support to which an applicator may be fastened. An applicator is a piece of material, such as lamb's wool or synthetic lamb's wool, which wraps around the body in such a manner that one of the two sides of the body is completely covered by the applicator. The edges of the applicator are secured to the second side of the body so that the applicator is fixed on the body and will not move when subjected to external forces. A handle is typically attached to the exposed second side of the body, extending in an upwardly direction.




A second type of application device is similar to the first device in all respects except for the applicator. Instead of having an applicator which is fastened about the body of the application device, the applicator material is directly attached to the body. Typically, the applicator material is a flocking or set of bristles which are glued or permanently attached to the application device.




A third type of application device consists of a tubular body to which an applicator is permanently attached. The applicator is securely fastened around the circumference of the tubular body. The tubular body typically contains a flat plate attached thereto for a detachable handle to be secured. This type of application device provides a smaller contact surface area then the device mentioned above.




Although the application devices currently used to apply coating materials to planar surfaces are sufficient to achieve adequate floor coatings, there are a number of problems associated with their use. One of those problems is wicking. As an application device spreads coating material over a surface, the coating material wicks throughout the applicator, saturating it with the coating material. Coating buildup on the applicator caused by such wicking can result in the uneven distribution of coating material over the surface. Excess coating material drips off of the back or the sides of the application device during normal use or splatters when trying to remove the excess coating from the applicator. The droplets disrupt the uniform nature of the coated surface, decreasing the quality of the finished coating.




Additionally, wicking presents undesired results when attempting to apply coating to a planar surface which contacts a perpendicular surface, such as where a floor and a wall join. Application of the coating material to the entire floor necessitates that the outer edges of the application device contact the wall at some point. If this contact occurs after coating material has wicked through the applicator, the coating is applied to the wall. This is undesirable.




Current solutions to rid the application device of unwanted coating buildup caused by wicking include forcing the excess coating material out of the applicator by squeezing the applicator against a hard surface or replacing the applicator. Often times, the squeezing or slapping of the applicator against a surface to rid the application device of the unwanted coating material results in a spattering of coating droplets which can disrupt a uniform surface which has already been coated. Replacing the applicator is also disadvantageous. Removing the applicator from the current application devices is time consuming and often very messy. The tubular application devices pose significant cleaning problems because the entire tube must be immersed in a solvent. This requires that large cleaning vessels filled with large amounts of solvent are kept on hand to clean the applicators.




Another problem associated with the application of coating materials to planar surfaces is the unevenness of the coating layers. The four to six inch wide application device tends to produce more variance in the thickness of coating layers than application devices with smaller application surface areas. In addition, the larger surface area requires a larger applicator, which provides more wool which can shed off of the applicator and deposit flaws in the coating layers. Likewise, the application device having the permanent applicator material attached thereto has been found to be prone to excess shedding of material into the coating layers. Such shedding creates flaws and imperfections in the coating layers which is undesirable.




The thickness of each coating layer is dependent upon the pressure applied to the application device by the individual spreading the coating. Various coatings have different viscosities, thus the pressure applied by the operator varies the thickness of the coating being applied. Typically, an operator becomes proficient with the various coatings and is able to apply the desired pressure necessary to achieve the desired coating thickness. However, this does not provide a standard, consistent force which produces uniform coating layers because it is very difficult to maintain a constant, and consistent downward force on the application device.




BRIEF SUMMARY OF THE INVENTION




The current invention comprises a floor coating application device for the application of coatings to planar surfaces such as hardwood floors, concrete floors, and the like, including a rigid body, an applicator, a force control system, and a handle.




The body of the application device is made of a rigid material unreactive to the coating materials and solvents used in the art. The body has at least one planar surface which is used in substantial parallel proximity to a surface being coated. The ends of the body are beveled or curved to prevent the transfer of coating material to surfaces perpendicular to the surface being coated, such as walls. The edges of the body are radially curved to improve the displacement of a coating material along the body edges during use.




Fasteners, such as VELCRO™, screws, other threaded fasteners, or hooks may be secured to the sides of the body to facilitate the connection of the applicator to the body. Likewise, the top surface of the body is fitted configured for a force control system removably connected to the body.




The applicator is removably connected to the body of the application device in such a manner that a portion of the applicator covers the planar surface of the body. At least the portion of the applicator covering the planar surface of the body is typically a piece of lamb's wool or synthetic lamb's wool. Naturally tanned lamb's wool is the preferred material because it does not shed. The edges of the applicator may be reenforced with leather strips in order to decrease the amount of wicking through the applicator and improve the strength of the connection between the applicator and the body of the application device.




The force control system connected to the body of the application device provides a consistent force to the body which improves the uniformity of the coating thickness layers applied with the application device and which provides the proper amount of force on the application device necessary to apply a variety of coatings. The typical force control system includes one or more weights, such as a polished brass weight connected to a top surface of the body. The system of weights is removable.




A handle is typically attached to the body or to a handle attachment which is attached to the body. The attachment between the handle and the body may allow the position of the handle, with respect to the body, to be altered. In addition, the handle may be secured in a specific position.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS




Referencing

FIGS. 1 and 2

, a preferred embodiment of the floor coating application device


10


is shown. The application device


10


comprises a body


12


, an applicator


40


, a force control system


50


, a handle


60


and a handle attachment


70


.




Different embodiments of the body


12


are depicted in

FIGS. 6-8

. Each embodiment, however, has certain standard features. The body


12


of the application device


10


is made of a substantially rigid material, such as hard maple wood, steel, aluminum, a high density polyethelene or other plastic, wood or a metal materials, or a combination thereof. It is important that the material of the body


12


does not react with the various coating materials and solvents that are used in the floor coating art. The ends


11


of the body


12


are beveled or curved inward at a desired angle or radius of curvature wherein the bottom surface


20


having a greater or longer length than that of the top surface


28


. An application device


10


having a body


12


with beveled ends


11


is desirous because the beveled ends


11


prevent coating material from transferring to a wall or other planar surface perpendicular to the surface that is being coated. The length and width of the body


12


may vary depending upon the job at hand. However, a body


12


having a length of about or approximately eighteen inches and a width of about or approximately one inch has been found to provide the application of substantially uniform coatings. Having a body


12


width, typically in the range of about or approximately one to two inches, smaller than the typical four to six inch width of prior art devices greatly improves the uniformity of the coating layer and decreases the number of imperfections that may appear in the coating layer as a result of the applicator shedding.




A preferred embodiment of the body


12


is illustrated in

FIGS. 6 and 7

. Although the body


12


of the application device


10


may be any shape, the footprint of the bottom surface


20


of the body


12


is essentially a rectangle having a length “L” of about or approximately eighteen inches and a width “W” of about or approximately one inch, although a width of approximately two inches or slightly greater may be used. A first bottom edge


23


extending along the length of the body


12


radially connects the bottom surface


20


with a first side surface


21


. Likewise, a second bottom edge


24


extending along the length of the body


12


radially connects the bottom surface


20


with a second side surface


22


. Both side surfaces


21


,


22


slope inward from the edges


23


,


24


to a top surface


28


.




The radially curved nature of the bottom edges


23


,


24


controls the size of the coating material fillet, such as decreasing the size of the coating fillet that accumulates between the applicator


40


and the surface being coated. The radially curved nature of the edges


23


,


24


also controls the wicking of coating material, such as decreasing the amount of wicking which occurs between the coating material and the applicator


40


. Such control features of the bottom edges


23


,


24


help to provide a more uniform layer of coating material and reliable application of a layer of coating material to the application surface.




The body


12


may also be constructed in a manner to decrease the amount of wicking that occurs up the side surfaces


21


,


22


of the body


12


. As illustrated in

FIG. 8

, fitting the side surfaces


21


,


22


of the body


12


with dams


27


, of any suitable geometric size and shape which will prevent coating material from depositing on the body


12


above the dams


27


. This decreases the potential for coating buildup on the body


12


of the application device


10


. Wicking may also be decreased by covering the side surfaces


21


,


22


of the body


12


with a slick low surface tension material such as TEFLON™, (polytetrafluoroethylene) or the like. Use of either a TEFLON™ or similar covering over the body


12


or dams


27


on the side surfaces


21


,


22


of the body


12


reduces coating buildup, resulting in fewer flaws due to coating droplets falling onto the finished coating surface during application or when squegeeing the applicator


40


.





FIGS. 1 and 2

illustrate a substantially or approximately cubic, or square cross-sectional body


12


, an alternative embodiment of the body


12


. Such a cubic body


12


provides a greater surface area on the top surface


28


. The larger top surface


28


facilitates the attachment of a larger force control system


50


.




Fasteners


25


,


26


may be fixed to the first and second side surfaces


21


,


22


of the body


12


to anchor the applicator


40


to the body


12


. The fasteners


25


,


26


in the preferred embodiment are strips of VELCRO™ (hook and loop fasteners) hooks which are permanently affixed to the body


12


. The fasteners


45


,


47


of the applicator


40


mesh with the fasteners


25


,


26


of the body


12


, securely anchoring the applicator


40


around the bottom surface


20


and side surfaces


21


,


22


of the body


12


. Although the fasteners


25


,


26


illustrated in

FIG. 6

terminate on the side surfaces


21


,


22


of the body


12


, it is sometimes desirous for the fasteners


25


,


26


to extend over different portions of the bottom surface


20


and side surfaces


21


,


22


of the body


12


, including the edges


23


,


24


. Typically, the applicator


40


is temporarily anchored to the body


12


in order to facilitate easy attachment and removal of the applicator


40


. However, the applicator


40


may be permanently anchored to the body


12


with such things as glue, staples, screws, other threaded fasteners, nails and the like. However, it is preferred that the applicator


40


be easily detachable from the body


12


with minimal effort, regardless of the fastening system used.




The top surface


28


of the body


12


may be fitted to hold a force control system


50


which aids in the distribution of an even pressure or force between the application device


10


and the coating being applied to a surface. The force control system


50


may be attached to the top surface


28


of the body


12


in any manner. The top surface


28


may be formed with a curvature such that a cylindrical force control system


50


would rest snugly on the complementary top surface


28


of body


12


(see broken lines in FIG.


2


). The force control system


50


may also be attached to the top surface


28


using fastener straps (see broken lines in

FIG. 2

) attached to the top surface


28


of the body


12


. In addition, it has been found that the body


12


may be fitted with pegs or suitable threaded fasteners


58


which extend upwards from the top surface


28


in such a manner that a force control system


50


having receptacles for the pegs or fasteners


58


may fit snugly over the pegs or fasteners


58


, resting on the top surface


28


. The pegs or fasteners


58


may also be threaded in manner to accept a wing nut


59


or other fastening device to secure the force control system


50


to the body


12


of the application device


10


. The method of attaching the force control system


50


to the body


12


may vary, as long as the force control system


50


is easily removable and fits snugly and securely to the body


12


of the application device


10


during use and operation of the application device


10


.




Additionally, the top surface


28


or one of the side surfaces


21


,


22


of the body


12


may be fitted to accept a handle attachment


70


or the direct attachment of a handle


60


.

FIG. 1

illustrates a handle attachment


70


fitted into a recess


29


on the top surface


28


of the body


12


. The recess


29


is illustrated in FIG.


7


. One version of the handle attachment


70


is illustrated in FIG.


9


. Typically, the handle attachment


70


is a metal plate, or similar sturdy material, which facilitates the attachment of a handle


60


to the body


12


. A front edge


72


of the handle attachment


70


may be fitted into the recess


29


of the body


12


and secured thereto. The handle attachment


70


may be secured to the body


12


with glue, screws, bolts, nails, or any suitable similar type attachment devices of sufficient strength. The handle attachment


70


illustrated in

FIG. 9

may have at least one eyelet


71


, which will allow a suitable fastener, such as a threaded fastener, screw, or nail to be used to secure the handle attachment


70


within the recess


29


of the body


12


. The handle attachment may also be secured to one of the side surfaces


21


,


22


of the body


12


. It is important that the handle attachment


70


or the handle


60


do not interfere with the force control system


50


.




The applicator


40


must be constructed of a material which does not shed particles during use because such particles are deposited in the coating surface causing imperfections which are undesirable. Typically, a piece of lamb's wool or synthetic lamb's wool is used as the applicator


40


because the lamb's wool has minimal shedding. For oil based materials or the like, the ideal material is natural lamb's wool that has been tanned naturally with chromium, for minimizing the amount of shedding of wool. The lanolin in the naturally tanned lamb's wool helps to improve the life of the applicator


40


and to decrease the amount of shedding or breakage of wool fibers that occurs. Typically, the lamb's wool is used to apply oil based coating materials and the like, while the synthetic lamb's wool is used to apply water based coating materials and the like.





FIG. 3

illustrates the preferred embodiment of the applicator


40


for the application device


10


. Although the shape of the applicator


40


illustrated is matched to fit the body


12


of the application device


10


, rectangular or differently shaped applicators


40


may also be used. The application material


42


has two sides, an application side and a back side. The back side is the side that contacts the body


12


of the application device


10


. Two leather strips


41


,


43


are attached to opposite edges of the backside of the application material


42


. The leather strips


41


,


43


may overlap the application material


42


or extend beyond the edge of the application material


42


. The leather strips


41


,


43


provide additional support to the applicator


40


while providing a surface upon which a fastener device


45


,


47


such as Velcro™ hooks may be attached. The applicator


40


is attached to the body


12


of the application device


10


by connecting one fastener device


45


with one of the fasteners


26


of the body


12


and the other fastener device


47


with the second fastener


25


of the body


12


.




In addition to providing additional support to the applicator


40


, it has been found that the leather strips


41


,


43


help prevent wicking through the applicator


40


up the sides of the body


12


of the application device


10


. The leather strips


41


,


43


act as a dam, preventing the coating material from wicking away from the surface of the applicator


40


in contact with the bottom surface


20


of the body


12


. This helps reduce excess buildup of coating on the applicator


40


and the body


12


, thus preventing imperfections in the coating surface caused by droplets of coating disengaging from the applicator


40


.




The smaller size of the applicator


40


used with the application device


10


has numerous advantages. First, a smaller amount of solvent and smaller containers are required to clean the applicator


40


. Applicators


40


are typically cleaned and reused after each job. Cleaning the applicator


40


involves immersing the applicator


40


in a solution which will dissolve the coating material that has soaked into the applicator


40


during the application process. Water is used to clean applicators


40


which have been used to apply water based coatings, while a solvent of some sort is typically used to clean the applicators


40


which have been used with oil based solvents. The applicators used in the current art must be cleaned in large containers because of their size. The smaller size of the applicators of the current invention allow easier cleaning at the job site while decreasing the amount of solvent that must be used.




The second advantage to using a smaller piece of application material


42


to construct the applicator


40


is a cost savings. Naturally tanned lamb's wool is relatively expensive. The decreased size of the application material


42


required in the current invention decreases the cost of the applicator


40


while providing a superior finish in the coating applications.




A third advantage to using a smaller flexible piece of application material


42


is that it may be easily packaged and readily transported as well as displayed for sale.




It may be necessary at times to attach a removable force control system


50


to the body


12


. The force control system


50


may be a single weight capable of spanning either less than or the entire length of the body


12


of the application device


10


, or it may be a series of separate weights attached to the body


12


at different locations, as well as stacked, one upon another, on the application device


10


as required. Changing the weight of the force control system


50


increases or decreases the pressure or force exerted by the body


12


on the coating material and surface which is being coated. Varying the total weight of the force control system


50


allows the operator to precisely control the pressure applied to the body


12


thus improving the uniformity of the coating layers and quality of the coating. Therefore, it is important to have a force control system


50


which may be easily removed and changed with a lighter or heavier force control system


50


depending upon the characteristics of the coating material that will be spread with the application device.




The preferred embodiment of the force control system


50


is illustrated in FIG.


4


. The preferred force control system


50


is a solid piece of polished brass having at least two recesses


52


to accept the pegs


58


(see

FIG. 2

) of the body


12


when attached to the application device


10


. The presence of at least two recesses


52


prevents the force control system


50


from moving when attached to the body


12


of the application device


10


. The force control system


50


may consist of any metal or material capable of providing the amount of weight necessary to produce the desired coating thickness. The force control system


50


may have a rectangular, cylindrical or other shape, as long as the desired total weight is able to be achieved. Additionally, the force control system


50


may consist of more than one weight, any desired number (see broken lines in FIG.


4


), and may be fastened or attached to the body


12


in a different manner, such as being attached by fastener strips anchored to the body


12


of the application device


10


.




The force control system


50


in the current invention greatly improves the uniformity of the coating surfaces applied using the application device


10


. The force control system


50


places a uniform force upon the body


12


of the application device


10


which may be easily changed to adapt to the characteristics and requirements for the different types of coatings. More weight can be added to the force control system


50


to produce a thinner layer of coating or to apply a coating having a thicker viscosity. Likewise, weight can be removed from the force control system


50


when a thicker coating of material is desired or where the viscosity of the coating material is such that very little force is needed to ideally spread the coating material. Prior to the current invention, the thickness of the coating layers depended upon the pressure that an operator manually applied to an application device. Coating layers applied in such a manner are often irregular because the pressure applied by the operator constantly varies. Use of the force control system


50


ensures the uniformity of the coating layer by removing much of the human factor in the application process. In addition, the force control system


50


takes some of the guesswork and the skill out of applying a coating material to surfaces. The force control system


50


enables those who are not skilled, or who have limited skill, in the art of applying coating surfaces, to produce a uniform coating layer without any, or little, experience.




A handle


60


is connected to either the body


12


of the application device


10


or to a handle attachment


70


secured to the body


12


. The handle


60


is made of a material sturdy enough to withstand forces placed upon it by the operator of the application device


10


during normal use. The handle


60


must be able to withstand the forces placed upon it when a person taps, knocks, slaps or attempts to squeeze any excess coating material off of the applicator


40


while it is still attached to the body


12


. Such forces include the weight of the operator pressing on the handle


60


with sufficient force to squeeze excess coating material out of the applicator


40


. In order to withstand such forces, the handle


60


is typically constructed of a hard wood, a metal or high density polyethelene, carbon fiber resin material, or polycarbonate material. The handle


60


may be any shape, size or length as long as it facilitates the use of the application device


10


.




In the preferred embodiment, the handle


60


is attached to a handle attachment


70


which is secured to the body


12


. The handle


60


may be attached to the handle attachment


70


using various configurations. There are situations where it is desirous to have a handle


60


permanently fixed to the handle attachment


70


and other situations where the handle


60


must be able to rotate on the handle attachment


70


. A fixed connection between the handle


60


and handle attachment


70


may be accomplished using a bolt and nut combination


74


to join the two parts as illustrated in FIG.


1


. The bolt may also be fitted with a wing nut. Such a configuration allows the wing nut to be loosened, the handle


60


to be rotated, and the wing nut tightened in order to fix the handle


60


in a new position on the handle attachment


70


.




A configuration allowing the handle


60


to rotate about the handle attachment


70


during operation of the application device


10


is a fork connection as illustrated in FIG.


2


. The base of the handle


60


separates into an upper fork portion


61


and a lower fork portion


62


between which there is enough space for the handle attachment


70


to fit. The upper and lower fork portions


61


,


62


may be secured to the handle attachment


70


with a nut and bolt combination or with a sealed bearing system. Use of a sealed bearing system allows the handle


60


to rotate about the handle attachment


70


while using the application device


10


. A sealed bearing system


84


(

FIG. 1

) may be used to prevent the freezing of the rotational quality of the handle


60


due to excessive coating buildup that may occur.




The handle


60


may also be attached directly to the body


12


of the application device


10


without using a handle attachment


70


. Additionally, the handle attachment


70


may be configured to secure the body


12


to a mechanical floor coating device instead of to a handle.





FIG. 5

illustrates another embodiment


10


′ of an application device


10


of the present invention. This embodiment comprises a container


80


, having a recessed bottom surface


82


and side walls


81


, for holding and distributing a coating material. The container


80


has a plurality of openings


83


for the gravitational distribution of liquid coating materials. Two bodies


12


are attached by their top surfaces


28


to the bottom surface


82


of the container


80


. The attachment between the bodies


12


and the bottom surface


82


of the container


80


must be such that the bodies


12


will not separate from the container


80


as the application device


10


is pushed or pulled across a planar surface. The container


80


of the application device


10


is attached to a handle attachment


70


and a handle so that the application device


10


may be pushed or pulled across a surface to be coated. As the application device


10


is pushed or pulled across the surface being covered, coating material is dispensed through the openings


83


in the container


80


and evenly spread by the bodies


12


attached to the bottom surface


82


of the container


80


. Application of the coating material is thus achieved in substantially the same manner as with the application device embodiments previously explained.




In the embodiment


10


′ of the application device


10


, the force control system


50


includes the container


80


and the amount of coating material


86


included therein. The weight of the container


80


may vary, depending upon the type of coating material to be used, as well as the amount or volume of the coating material contained within container


80


. The thickness of the container


80


may vary (shown by broken lines in

FIG. 5

) to control the force exerted on the bodies


12


.




It is understood that additions, deletions, modifications, and other changes to the invention may be made which are within the scope of the invention as described and claimed herein.
