The present disclosure relates generally to the field of drywall hanging and finishing. More particularly, the present disclosure relates to handheld tools for finishing drywall. Specifically, the present disclosure relates to a handheld tool for shaping and finishing drywall mud.
Drywall, which can also be known as plaster wallboard, sheetrock, or gypsum board, is a common wallcovering and construction material in the U. S. and throughout the world. Drywall is commonly installed on interior walls and ceilings in homes and businesses by attaching sheets of the material to framing studs in order to form a wall or ceiling covering. Once installed, drywall is typically put through a finishing process that includes applying a paper tape over spaces between adjacent drywall sheets, applying mud over the paper tape and portions of the sheets, and then shaping the mud to achieve a smooth and uniform finish on the drywall surface.
The finish of drywall is typically measured in levels with level zero being installation of drywall sheets with no additional steps taken and level five being the highest degree of finishing, giving the surface of the drywall a smooth and virtually blemish-free appearance. Levels one through four represent varying degrees of finish therebetween. The finishing process can be time consuming, taking as many as three to four days to reach a level four or five finish. One of the main reasons for this extended timeframe is the need to apply a joint compound, commonly called drywall mud, to the surface of the drywall in multiple coats or layers allowing each layer time to dry. Once a layer is dry it is sanded or smoothed, and is often contoured, prior to applying the next layer.
The standard process of finishing drywall is achieved using multiple drywall taping knives of varying widths, the most common being 5″, 8″, and 10″ wide knives, along with drywall mud and paper drywall tape. Typical steps of finishing drywall include applying a first layer of drywall mud into screw holes and/or joints between the drywall sheets. This is typically done using a flexible drywall taping knife. A strip of paper tape is typically positioned over the joint between two adjacent drywall sheets and then a layer of drywall mud is applied over the tape. In some instances, the paper tape may have an adhesive backing and the tape is adhered to the drywall sheets prior to application of the first layer of drywall mud. In other instances, the paper tape does not include any adhesive and so a quantity of mud is applied to a region of the drywall sheets adjacent a joint, the paper tape is positioned over the joint and is secured in place by the quantity of mud, and then the first layer of drywall mud is applied over the tape. Sufficient time is given to allow the mud applied over the paper tape and in any screw holes to dry before proceeding with the next step.
Once the base layer (i.e., the first layer) is dry, a next layer is applied over the first layer using a slightly wider drywall knife. This next layer is additionally given time to dry and then it is typically sanded smooth before proceeding with the application of another layer. Depending upon the level of finish desired, as many as three or four layers of drywall mud may be applied. At level five, a skim coat of drywall mud can be applied to the entire wall or ceiling surface. Each layer of drywall mud that is applied requires sanding and smoothing before proceeding with the next layer. Additionally, each layer is usually feathered to properly blend the mud into the wall or ceiling to create a uniform appearance. Once the desired finishing level is achieved, the wall can be primed and painted or prepared for wallpapering, tile, or any other wall coating as desired by the installer or homeowner.
The process of finishing drywall is difficult as it requires proper blending of the mud to hide imperfections and seams in the drywall and is often performed by a skilled tradesman having many years of experience. Even then, errors in the finishing process can result in damage to the drywall and/or the need to reapply mud, both of which can increase costs and time needed to finish a wall.
One PRIOR ART device is disclosed in U. S. Patent Publication No. 2017/0058539 which shows an apparatus for smoothing drywall mud that includes a bladed tool designed to smooth and shape unfinished, cured drywall mud. The tool described in the '539 publication includes one or more flexible blades that can be bent or curved utilizing adjustment screws or adjustment means to secure the one or more blades in a curved position. The tool disclosed therein is designed to be installed on a pole to assist the operator in controlling the shaping tool. One embodiment of the prior art device described in the '539 publication is not easily adapted to changing conditions of the drywall and drywall mud as it requires use of adjustment screws to change the shape and curvature of the blade. This requires the operator to stop work to adjust the tool anytime a different profile is desired or anytime a non-uniform condition is present. This can result in multiple adjustments of the tool being necessary during the finishing process which can cause the operator to lose the time that might have been saved using the disclosed tool.
Another embodiment of the prior art device described in the '539 publication requires use of multiple spring loaded pistons to flex blades. This embodiment can adjust according to the contour of the wall, but may cause the blades to adjust over the unfinished drywall mud rather than cutting through the mud. Further, the inclusion of multiple spring loaded pistons requires additional maintenance and cleaning as dust and debris can become lodged within the springs during use and can diminish performance over time.
Provided are methods and tools to insure proper blending and smoothing of drywall mud that are easy to use and provide a consistent finish even in the hands of an unskilled person or a person with less experience. Further provided is a tool that can be adjusted “on the fly” with little or no down time from the finishing process. Also provided is a tool that can collect and contain dust and debris created during the finishing process which can both speed up the finishing process and reduce clean-up time.
A drywall mud-shaping tool and a method of using the same to finish cured drywall mud is disclosed. The tool has a flexible blade that does not contact an exterior surface of a drywall sheet until pressure is applied to the blade. Pressure is applied to the blade by holding the tool's housing in a user's hands and pressing downwardly thereon while drawing the housing across the sheet's exterior surface. The pressure causes the blade to move from a first position where the blade is spaced a distance away from the drywall sheet, to a second position where the blade contacts the drywall sheet. The blade removes some cured drywall mud from the exterior surface and collects the same in a collection chamber provided in the tool housing. The housing may be moved across the drywall sheet's exterior surface a number of times to finish the cured drywall mud.
In one aspect, the present disclosure may provide a drywall mud-shaping tool comprising a main body housing having a bottom adapted to be placed in contact with an exterior surface of a sheet of drywall; a blade provided on the main body housing; wherein said blade is movable between a first position and a second position upon application of pressure to the main body housing; wherein when the blade is in the first position, the blade is adapted to be spaced a distance away from the exterior surface of the sheet of drywall; and wherein when the blade is in the second position, the blade is adapted to contact the exterior surface of the sheet of drywall.
In another aspect, the present disclosure may provide a method of shaping drywall mud comprising the steps of applying wet drywall mud to an exterior surface of a sheet of drywall; allowing sufficient time for the drywall mud to cure; placing a drywall mud-shaping tool against the exterior surface of the sheet of drywall; hand-applying pressure to a main body housing of the drywall mud-shaping tool in a direction oriented at right angles to the exterior surface; moving a blade provided in the main body housing from a first position to a second position relative to a top of the main body housing; contacting cured drywall mud with an edge of the blade when the blade is in the second position; drawing the drywall mud-shaping tool across the cured drywall mud in a direction substantially parallel to the plane of the exterior surface of the drywall sheet; and removing some of the cured drywall mud from the exterior surface of the drywall sheet using the blade.
In another aspect, the present disclosure may provide a method of finishing drywall comprising the steps of applying wet drywall mud to an exterior surface of a drywall sheet; allowing sufficient time for the drywall mud to cure; placing a contoured edge of a flexible blade against the exterior surface of the drywall sheet; applying pressure to the main body housing; contacting an unfinished surface of the cured drywall mud with the blade while applying pressure; drawing the blade across the unfinished surface of the cured drywall mud; removing some of the cured drywall mud from the exterior surface with the contoured edge of the blade; contouring the cured drywall mud with the contoured edge of the blade to form a contoured surface; releasing pressure on the main body housing; placing a straight edge of the flexible blade against the exterior surface of the drywall sheet; applying pressure to the main body housing; contacting the contoured surface with the straight edge of the blade while applying pressure; drawing the blade across the contoured surface; removing some of the cured drywall mud from the contoured surface; and forming a finished surface of the cured drywall mud on the exterior surface of the drywall sheet.
A sample embodiment of the disclosure is set forth in the following description, is shown in the drawings and is particularly and distinctly pointed out and set forth in the appended claims. The accompanying drawings, which are fully incorporated herein and constitute a part of the specification, illustrate various examples, methods, and other example embodiments of various aspects of the disclosure. One of ordinary skill in the art will appreciate that in some examples one element may be designed as multiple elements or that multiple elements may be designed as one element.

As best seen in
Blade 50 is engaged with main body housing 12 and can be flexible under pressure but can maintain a generally rectangular shape in each of a flexed condition or an un-flexed condition. Wheels 34 are engaged with the main body housing 12 and a region of each wheel 34 is adapted to contact an exterior surface of a sheet of drywall when tool 10 is used. Blade 50 is positioned on main body housing 12 such that a bottom edge of the blade is located inwardly of a region of the wheels that contacts the exterior surface of the sheet of drywall when the blade 50 is in a first position. When pressure is applied to the main body housing 12 and thereby to blade 50, blade moves to a second position where the bottom edge of the blade 50 will contact the exterior surface off the sheet of drywall (or will contact drywall mud applied to the exterior surface of the drywall sheet). In other words, when blade 50 is in the second condition, the position of the bottom edge of blade 50 is substantially aligned (or flush) with the regions of the wheels 34 that contact the exterior surface of the drywall sheet. Blade 50 is in the first position when in an un-flexed condition and is in the second position when in the flexed condition.
As shown in
First longitudinal edge 78 and second longitudinal edge 80 of blade 50 can be precision machined to include four cutting edges 78A, 78B, 80A, and 80 B. Blade 50 may be selectively removed from main body housing 12 and may be reversed or flipped to present a selected one of the four cutting edges 78A, 78B, 80A, and 80 B. Cutting edges 78A, 78B, 80A, and/or 80B can be configured to each be used before blade 50 needs to be replaced. Blade 50 may therefore be initially engaged in main body housing 12 in a first orientation where a first cutting edge is presented for contact with the exterior surface of the drywall sheet; and blade 50 may later be flipped to a second orientation where a second cutting edge is presented for contact with the exterior surface of the drywall sheet.
According to another aspect, cutting edges 78A, 78B, 80A, and/or 80B can have differing profiles on a single blade 50. By way of one non-limiting example, one or more cutting edges 78A, 78B, 80A, and/or 80B can be straight edges while one or more of the cutting edges 78A, 78B, 80A, and/or 80B may be contoured edges. Contoured edges can have any edge profile as chosen by a person of ordinary skill in the art.
Corners 80 of blade 50 can be rounded to minimize likelihood of corners 80 inadvertently digging into the drywall or drywall mud and damaging the same. According to another aspect, corners 80 can be of any desired profile shape as chosen by a person of ordinary skill in the art.
According to one aspect, blade 50 can be constructed of a metal strip, such as steel, and can be of any thickness suitable that will permit blade to flex under applied pressure. For example, blade 50 may have a thickness of about 0.8 millimeters. According to another aspect, the thickness of blade 50 can vary according to the desired application and use of shaping tool 10, provided that blade 50 is not of a thickness that prevents blade 50 from flexing under appropriate pressure, as discussed below.
With reference to
Although described herein as set at a fixed angle, it will be understood that blade assembly 14 and/or main body 12 can include an angle adjustment feature which can allow the angle of blade 50 to be adjusted according to the desired application. By way of one non-limiting example, thumbscrews 54, 56 can be configured to adjust the angle of blade assembly 14 thereby adjusting the angle of blade 50 as a result.
Blade assembly 14 can fasten and hold blade 50 to front side 24 of main body 12. First longitudinal edge 80 of blade 50 can sit against the bottom side of first alignment stop 71 and second alignment stop 72 while first and second blade apertures 74 and 76 can align with and accept first and second mounting tabs 70, 72, respectively. This assures proper placement of blade 50 within blade assembly 14. Further, first and second mounting tab 68 and 70 can be selectively shaped to secure blade 50 in place and help prevent horizontal and/or vertical movement of blade 50.
First and second attachment members 62, 64, which carry first and second pass-through openings 66, 68, respectively, can be placed over and against blade 50 with first and second pass-through openings 66 and 68 aligned with corresponding first and second threaded receivers 58 and 60. First attachment member 62 can rest under and against first attachment stop 63 and second attachment member can rest under and against second attachment stop 65. Attachment stops 63 and 65 can ensure proper alignment of first and second pass-through openings 66, 68 with first and second threaded receivers 58, 60. Pass-through openings 66 and 68 can be sized to allow first thumb screw 54 and second thumb screw 56 to pass through first attachment member 62 and second attachment member 64 into first threaded receiver 58 and second receiver 33. The inclusion of first attachment member 62 and second attachment member 64 can serve to place uniform pressure across the face of blade 50, helping to further secure blade 50 to front side 24 of shaping tool 10. The first and second thumb screws 54 and 56 can allow adjustment of the pressure on the blade 50 and can provide for easy access to, and/or replacement of, blade 50.
According to one aspect, thumb screws 54 and 56 can be clips, pins, or any other fastening device as chosen by a person of ordinary skill in the art.
Blade assembly 14 can further include a blade cover 48 having a lip 49 corresponding to protrusion 29 of top 28 of main body 12. Alignment of lip 49 with protrusion 29 can ensure proper positioning of blade cover 48 on blade 50. Blade cover 48 can extend longitudinally across blade 50, terminating interior of first and second attachment members 62, 64. Blade cover 48 can further include one or more magnets 52 to attach blade cover 48 to blade 50.
According to one aspect, magnet 52 can extend approximately the entire longitudinal length of blade cover 48.
According to another aspect, multiple magnets 52 can be attached to blade cover 48.
According to another aspect, blade cover 48 can itself be a magnet thereby making the entire blade cover 48 magnetic and capable of attaching to blade 50.
Blade cover 48 can be constructed of rubber or can be a rubber-coated material such as metal or plastic. The inclusion of rubber and/or a rubber coating on blade cover 48 can assist operator in gripping shaping tool 10 and allowing operator more control over shaping tool 10 and over the curvature of blade 50 (discussed further in operation below). Blade cover 48 can additionally help protect the operator from contacting the outer surface of blade 50 during operation of shaping tool 10 which can help in the prevention of injuries to the operator.
It will be understood that while blade cover 48 is shown and described herein as attaching to blade 50 via magnets 52, other attachment means could be substituted without deviating from the scope herein. By way of one non-limiting example, blade cover 48 can be adhesively attached to blade 50. Alternatively, blade cover 48 can extend behind first and second attachment members 62, 64 and can have one or more openings that allow blade cover 48 to attach to first and/or second mounting tabs 70, 72, first and/or second thumb screws 54, 56, or any combination thereof.
With reference to
Although disclosed herein as rubber, it will be understood that wiper 84 can be a brush or be comprised of a flexible material, such as plastic or silicone.
According to another aspect, wiper 84 may be replaced with a second blade for additional contouring and/or smoothing of an unfinished surface.
With reference to
As best seen when viewing
It will be understood that drywall frequently will be vertically oriented and that, in operation, wiper 84 will tend to be positioned a distance vertically below blade 50 during the contouring process. Accordingly, with the aid of gravity, dust and debris that is removed from the exterior surface by blade 50 is able to fall past collection chamber 18. The placement of wiper 84 can create a seal between shaping tool 10 and the surface being finished and can further help direct this dust and debris into collection chamber 18.
In continued operation, when collection chamber 18 is full or nearly full of dust and/or debris, collection chamber 18 can be emptied by removing shaping tool 10 from the surface being finished and dumping dust and debris from collection chamber 18 into an appropriate receptacle. The shaping tool 10 can then be repositioned against surface and the smoothing and contouring process with tool 10 can be continued.
According to another aspect, in embodiments where collection chamber 18 is covered, an additional step of removing the cover to access collection chamber 18 can be performed prior to dumping dust and debris from collection chamber 18. The cover is then repositioned over collection chamber 18 once dust and debris has been emptied therefrom.
Shaping tool 10 can be used to contour unfinished drywall mud through use of multiple blades (such as blade 50) with differing edge profiles. Shaping tool 10 can have a first blade that is contoured, curved, or otherwise shaped so that the first blade has an edge profile that is not straight. Shaping tool 10 may further be provided with a second, straight-edged blade that can be used in place of the contoured blade. One non-limiting example of a contoured edge profile that is not straight is an edge that is a serrated, or toothed, edge. According to this example, shaping tool 10 can be first drawn along drywall mud on the surface of the drywall using the first contoured-edged blade. Shaping tool 10 can then be switched and a second shaping tool 10 with a straight-edged blade can be drawn along the now at least partially contoured drywall mud. This arrangement can allow the user or operator to control the amount of drywall mud removed from surface in a single pass of tool 10 across the surface. This may help to reduce errors and/or damage to the drywall surface.
According to another aspect, both edge profiles can be carried in a single shaping tool 10 and the blades 50 can be swapped between finishing steps.
According to another aspect, a single blade 50 can have multiple edge profiles and can be removed, rotated, and replaced within a single shaping tool 10 between finishing steps.
In operation, blade 50 can be removed and replaced by following the steps of rotating thumb screws 54 and 56 counter-clockwise to loosen and/or remove them from first and second threaded receivers 58 and 60 respectively. Once thumb screws 54, 56 are loosened and/or removed, first and second attachment members 62 and 64 can be removed from the outer surface of blade 50. Blade cover 48 can be separated from blade 50 by separating magnets 52 or by removing the adhesive connector. Blade 50 can then be removed from first and second mounting tabs 70 and 72. Blade 50 can be flipped or rotated to place a new, unused cutting edge 78A, 78B, 80A, or 80B of either longitudinal edge 78 or 80, into proper cutting position. Once the desired cutting edge 78A, 78B, 80A, or 80B is oriented in the cutting position, blade 50 can be reinstalled onto first and second mounting tabs 70 and 72. First and second attachment members 62 and 64 can be placed over blade 50 and against first and second attachment stops 63 and 64. First and second thumb screws 54 and 56 can be inserted through pass-through openings 66 and 68 and into first and second threaded receivers 58 and 60. First and second thumb screws 54 and 56 can then be rotated clockwise and thereby secure blade 50 in place. Lip 49 of blade cover 48 can be aligned with protrusion 29 of cover 28 and blade cover can be secured to the exterior side of blade 50 via magnets 52.
According to one aspect, thumb screws 54, 56 can remain operatively attached to attachment members 62, 64. According to this aspect, thumb screws 54, 56 then do not need to be fully removed to rotate, flip, or replace blade 50.
According to another aspect, attachment members 62, 64 can be configured to open without being completely removed from body 12 while still allowing full access to blade 50.
In summary, the present disclosure may provide a drywall mud-shaping tool 10 comprising a main body housing 12 adapted to be placed in contact with an exterior surface of a sheet of drywall; and a blade 50 provided on the main body housing 12; wherein said blade 50 is movable between a first position and a second position relative to the top 28 of main body housing 12 upon application of pressure to the main body housing 12 (in the directions of arrow “A” and/or “B”); wherein when the blade 50 is in the first position, a bottom edge (either 78 or 80 depending on which cutting surface is being presented) of the blade 50 is adapted to be located a distance away from the exterior surface of the sheet of drywall; and wherein when the blade 50 is in the second position, the bottom edge (either 78 or 80) of blade 50 is adapted to contact the exterior surface of the sheet of drywall.

In another aspect, the present disclosure may provide a method of finishing drywall comprising the steps of applying wet drywall mud to an exterior surface of a drywall sheet; allowing sufficient time for the drywall mud to cure and become cured drywall mud; placing a contoured edge 78A, 78B, 80A or 80B of a flexible blade 50 against the exterior surface of the drywall sheet; applying pressure “A” (
According to one aspect, shaping tool 10 can be drawn across unfinished drywall in any direction while keeping blade 50 substantially parallel to the plane of the exterior surface of the drywall. According to this aspect, drywall tool 10 can provide a smoother finish than traditional sandpaper methods, which require the sandpaper to be applied in uniform strokes in the same direction throughout the process. Sandpaper that is applied in any direction can scratch or scar the mudded surface, a problem which can be minimized and/or eliminated through proper application of shaping tool 10.
