Definitions

  • This invention relates to finishing interior walls.
  • this invention relates to finishing the edges at intersections where two walls meet.
  • Drywall panels are widely used in the construction industry for forming the interior walls and ceilings of rooms. Drywall panels are made of a gypsum or reinforced gypsum core covered with paper. Drywall panels have the advantages of being easy to cut to desired sizes and to attach to assorted types of framing. However, it is very difficult to cut drywall panels so that the edges are perfectly straight and smooth and can meet to form a perfectly straight corner, which is aesthetically to be desired. In addition, when the drywall panels are cut to the desired sizes, the edges of the panels are left exposed. This exposed gypsum core is soft and tends to crumble unless the severed edges are somehow protected. This is especially important at outside wall corners.
  • drywall tape and metal corner beads Conventional drywall tape is provided in narrow, elongated ribbons or strips of porous paper wound into rolls. The paper is sometimes perforated to increase moisture penetration and to prevent air bubbles from being entrapped behind the tape.
  • the drywall tape is first applied to joints and edges of abutting drywall panels and is then covered with wet plaster, sometimes called "mud.”
  • the plaster is feathered and smoothed along the edges of the tape to conceal the demarcations between the tape edges and the drywall panels to which the tape is applied.
  • wet plaster has dried, the tape and drywall can be painted or otherwise covered with a suitable wall covering.
  • Coffered and vaulted ceilings have recently become very popular among home builders and buyers. Often the peak of such ceilings will form an acute angle. It is difficult to fit a conventional plaster trowel into such angles.
  • drywall tape is formed of paper, it is quite flexible and will conform to various surface configurations of the edges of intersecting panels of drywall.
  • conventional drywall tape is used at the outside corners of walls, the flexibility of the tape often results in a corner demarcation that is irregular, since the tape conforms to irregularities in the exposed, severed edges of the drywall panels.
  • the tape is also fragile and does not stand up well to the constant physical abuse suffered by outside corners. As a consequence, conventional drywall tape cannot be used at exposed outside corners.
  • metal corner beads are often used.
  • Conventional metal beads are configured in an L-shaped or angle-shaped cross section and are typically fabricated from elongated perforated strips of metal, such as galvanized steel, permanently deformed with a lengthwise 90-degree bend to form elongated angles.
  • the metal beading is typically positioned at the intersections of adjacent drywall panels that meet at right angles to form an outside corner within a room.
  • the sections of metal beading are nailed in place through the drywall panels to wooden supporting structural members located behind the drywall panels.
  • Wet plaster is then smoothed into place to cover the metal flanges or leg members of the metal beading, and the edges of the plaster are smoothed and feathered to attempt to conceal the metal edges.
  • the rigidity of the metal beading does allow an outside corner of an inside building wall to be finished with a sharp, straight edge, which is aesthetically pleasing
  • the use of metal beading involves some significant problems. Over time, the metal corner bead will rust, thereby producing rust stains that are clearly visible on the surfaces of the walls at the corner. It is not always possible to completely cover the edges of the metal flanges or the nail heads used to attach the metal corner bead to the drywall panel, detracting from the desired smooth appearance of the wall. Cracks often develop in the overlying plaster at the outer edges of the flanges.
  • the strips Because of the rough handling to which most of the material at a work site is subjected, it is not uncommon for the strips to be wrinkled, dented, and perhaps twisted, thus rendering them either unusable, or usable only to produce an inferior end result. In addition, the metal strips are used in large quantities in construction and can add up to considerable cost.
  • Stibolt et al. US-A-5,531,050, describes a drywall corner finishing device to form a corner between two panels of drywall.
  • the finishing device has a flexible joint with two wings attached forming a corner with an adjustable angle.
  • Swanson and Lamb describe plastic joint strips that can be reversibly bent to be adhesively secured to both inside and outside corners.
  • Baker shows an outside corner connector for waterbed pedestals in which the panels forming the pedestal are inserted into the connector.
  • Ellingson provides a double-layer wall member guard structure for outside corners made of a resilient material.
  • Weinar provides a plastic or metal T-shaped corner construction in which the post of the T sits between two abutting pieces of drywall and the cross bar lies atop the drywall panels. Part of the paper covering from one panel is wrapped around the cross bar to provide a finished appearance, leaving a ridge down one side of the corner. This corner construction can only be used on outside corners.
  • Schneller describes yet another type of metal outside corner bead in which an additional flange extends over the edge of the drywall board forming the outside corner. Ridges are left on both sides of the corner, and this corner bead can only be used on outside corners.
  • Bernard presents a plastic L-shaped outside corner cover that uses heat-shrinkable plastic tape along the arms both as a method of attachment and as a method of providing a smooth junction between the cover and the drywall.
  • This cover can be used for outside corners having a variety of angles.
  • Tucker provides a paper drywall ribbon having a centrally located plastic bead extending longitudinally along the ribbon. Plaster is used to attach the ribbon to the drywall. This plastic bead is designed to be used with outside corners only.
  • Conboy describes a plastic drywall tape that can be used on both inside and outside corners. Again, this plastic tape is held on the corner with plaster, and plaster is used to provide a finished appearance.
  • Tucker describes a stiff plastic strip with a curved center section and two flanges that is attached to outside or inside corners with adhesive. The flanges are then covered with paper tape strips and plaster.
  • Weldy provides a wall edging system for both inside and outside corners that comprises a plastic strip having an arcuate center portion to which are attached two flanges at right angles.
  • the strip is attached to the drywall with nails. Plaster is then smoothed over the strip to finish the edges. The side of the strip facing out toward the room can be finished with primer.
  • Ritchie et al. describe a corner bead for outside corners that has a metal core and that is completely covered by paper. This bead has a rounded nose and side flanges. The paper covering is further coated with a reinforcing emulsion. The corner bead is nailed to the drywall, and plaster is used to hide the edges.
  • Rutkowski et al. describe an elongate strip to be placed between the junctions of adjacent drywall boards forming a planar wall in order to absorb movement within the wall.
  • the strip has two flanges attached on either side of a central flexible portion.
  • Cannon describes a building in which the walls are inserted into corner posts.
  • the posts have two channels into which are place the edges of walls.
  • the walls are held within the channels by a bolt and corner plate that connects with cladding on the walls.
  • a finishing device is also needed that will simplify installation of drywall in acutely angled inside corners and minimize the need to use plaster.
  • drywall panels are made in a variety of thicknesses.
  • drywall panels may be 3 ⁇ 8 inch wide, 1 ⁇ 2 inch wide, 5 ⁇ 8 inch wide, or other widths.
  • a drywall corner finishing device that can be used for all thicknesses of drywall panel.
  • the drywall corner finishing device described herein can be used for both inside and outside corners having various angles. Builders will not have to order two or more versions to cover different types of corners.
  • the drywall corner finishing device described herein can also be used to cover two adjacent outside corners without requiring the use of a narrow strip of drywall panel between the corners and two finishing devices, one for each outside corner.
  • a layer of primer or laminate covers the side of the drywall corner finishing device of the present invention that faces into the room. Because of this primer or laminate layer, plaster need only be used on the outside edges of the corner finishing device where it abuts the drywall.
  • the drywall corner finishing device described herein has a width generally equal to that of the drywall panels, so that little plaster is needed to fill in the area where the drywall panels meet the finishing device.
  • the drywall corner finishing device of the present invention is capable of hiding crooked, uneven corners no matter how irregular the deviations may be.
  • the present drywall corner finishing device is nailed directly to the framing members of the wall, thereby providing stability.
  • the drywall corner finishing device is adjustable to fit various thicknesses of drywall panels.
  • a finishing device used to form a corner between two panels of drywall has a flexible joint and an expansion joint extending along a predetermined axis.
  • Two wings are connected to and extend outwardly in a diverging relation from the flexible joint to form a corner having an adjustable angle.
  • Each wing has a front surface with an edge, a rear surface with an edge.
  • the expansion joint and the flexible joint together allow the front surface edge and the rear surface edge to move apart in order to accommodate panels of drywall with different thicknesses.
  • a layer of primer or adhesive laminate is applied to the front surface of the wings so that paint or wallpaper or other wall coverings can bond to the front surface.
  • the finishing device is capable of forming both inside and outside corners. To form inside corners, the finishing device bends along the flexible joint. To form outside corners, strips parallel to the flexible joint are removed from the rear surface of the wings and the finishing device is folded along the openings thus created.
  • the left 102 and right 104 wings of the drywall corner finishing strip are attached to a flexible center joint 100 and extend outwardly therefrom to a distal edge 110.
  • the wings 102,104 have a front surface 106 and a rear surface 108.
  • the front surface 106 and rear surface 108 extend outwardly beyond the distal edge 110 of the wings 102,104 to cover the distal edge110.
  • the rear surface 108 of the device is juxtaposed to the framing of an interior wall while the front surface 106 faces out into the room, contiguous with the surface of the drywall panels forming the wall.
  • the front surface 1'06 may be covered with a layer of primer 300 as shown in FIG. 3 so that any paint or wallcovering that is eventually used to decorate the wall will adhere easily.
  • the front surface 106 may have an adhesive laminate 400 attached to it as shown in FIG. 4.
  • the structure of the drywall corner finishing device is more clearly seen in FIG. 2.
  • the flexible center joint 100 is preferably arcuate, but it is to be expressly understood that any joint shape, such as V-shaped, U-shaped, C-shaped, etc., can be used that allows the device to bend through a variety of angles at the center joint 100.
  • the center joint 100 extends along an axis that extends linearly to form a corner or edge.
  • a number of struts 206 separate the rear surface 108 of each wing 102, 104 from the front surface 106 of each wing 102, 104.
  • the pattern of struts206 provides stability to the structure of the corner device and also allows the device to be folded around outside corners as discussed in more detail below. It will be obvious to one skilled in the art that the pattern of struts 206 shown in Figs. 1 and 2 is not the only pattern that will provide these features of stability and folding and that other patterns would be suitable and are to be included in the present invention.
  • the edge 202 of the rear surface 108 extends beyond the edge 200 of the front surface 106.
  • the distal portion 204 of the front surface 106 tapers slightly toward the rear surface 108 so that, as discussed in more detail below, the edge of a drywall panel can be placed in the space 114 between the front surface 106 and the rear surface 108 such that the edge 202 of the rear surface 108 and the edge 200 of the front surface 200 are in close apposition to the drywall panel.
  • the rear surface 108 contains a number of removable strips 208, 210 that are removed when it is desired to fold the drywall corner finishing device around outside corners, as discussed in more detail below.
  • FIG. 8 illustrates the inside corner formed when a vertical wall meets a coffered or cathedral ceiling.
  • FIG. 9 shows the inside corner formed at the vault of such a ceiling. Depending on the design of the building, these corners may have angles ranging from less than 90 degrees to 180 degrees.
  • the drywall corner finishing device is used to finish an inside corner, the rear surface 108 is first placed directly against the framing.
  • the center joint 100 flexes from 180 degrees, shown in FIG. 6, to the appropriate angle needed to fit the angle made by the corner, as shown by arrow 500 in FIG. 5 and arrow 700 in FIG. 7.
  • the finishing device is attached to the wall framing 800 and ceiling rafter 802 by use of nails 806.
  • the finishing device is made of plastic soft enough to permit the nails 806 to be driven through the flange 112 of the rear surface 108 without the need for pre-formed holes. It is to be expressly understood that other methods such as the use of screws, bolts, adhesive, etc.. will be equally efficacious in attaching the finishing device to the supporting members of the wall or ceiling.
  • the attachment location of the device and the positions of the nails 806 can be varied to enable the device to correct inequalities that may exist within the framing and from one framing member 800 to the next. If necessary, shims may be placed behind the device before it is attached by nails 806.
  • the edges of the drywall panels 804 are inserted into the spaces 114 between the front surface 106 and rear surface 108, such that the edges of the drywall panels 804 abut the distal edges 110 of the wings 102, 104. It can be seen in FIG. 8 that the spaces 114 between the front surface 106 and rear surface 108 are just large enough to accommodate the drywall panels 804 and that the front surface 106 and rear surface 108 are closely juxtaposed to the drywall panels 804. The drywall panels 804 thus hide the nails 806.
  • the drywall panels 804 are attached to the framing 800 and rafter 802 in the usual fashion.
  • plaster 1300 is then applied to the tapered distal portion 204 of the front surface 106 and the tapered edge of the drywall panel 804 to hide the edge 200 and provide a smooth, level surface. Because plaster 1300 is applied only to the tapered portion 204 of the finishing device, difficulties inherent in plastering within corners are avoided. Such difficulties include, among others, the difficulty in maneuvering a plaster trowel within a corner, the skill needed to produce a perfectly straight edge where the two sides of the corner meet, and the need for several layers of plaster 1300 to completely hide the joint between the finishing device and the drywall or to correct the inequalities resulting from mis-sized, mis-placed, or warped framing members, with each layer requiring considerable time to dry.
  • the surface of the wall can be finished by painting, wallpapering, or any other method desired.
  • the primer 300 bonded to the front surface 106 enables paint or other wallcoverings to adhere to the front surface 106 of the finishing device.
  • a laminate 400 can be adhesively affixed to the front surface 106 to provide a surface for subsequent painting.
  • FIG. 9 A second example of the use of the finishing device for inside corners is shown in FIG. 9.
  • the finishing device provides an inside corner essentially as described above, except here the corner is that formed by the vault of a coffered ceiling.
  • the device is attached to the rafters 900 by driving nails 904 through the flanges 112.
  • the attachment location of the device and the positions of the nails 904 can be varied to enable the device to correct inequalities that may exist within the rafters 900 and from one rafter 900 to the next.
  • shims may be placed behind the device before it is attached by nails 904.
  • the edges of the drywall panels 902 are then inserted into the spaces 114 between the front surface 106 and rear surface 108.
  • these spaces 114 are just large enough to accommodate the edges of the drywall panels 902, so that the front surface 106 and rear surface 108 are in close apposition to the drywall panels 902.
  • the drywall panels 902 thus hide the nails 904.
  • the drywall panels 902 are attached to the rafters 900 in the usual fashion. Plaster 1300 is then applied to the tapered distal portion 204 of the front surface 106 and the edge of drywall panels 902 to provide an even surface. Because of the primer 300 or laminate 400 covering the front surface 106, it is not necessary to use plaster on the remainder of the front surface 106, and the difficulties of plastering within the tight angles formed by inner corners are avoided.
  • the surface of the wall is then painted or otherwise finished as desired.
  • FIGs. 10 and 11 illustrates outside corners formed by 2-by-4 framing boards 1000. 1002. and FIG. 11 shows outside corners formed by 2-by-6 framing boards 1100, 1102.
  • the rear surface 108 contains at least two sets of removable strips 208, 210. It is to be expressly understood that the removable strips 208, 210 can be located in any convenient place on the rear surface 108 and is not limited to the locations of the strips 208, 210 shown. Strips 208 are removed when 2-by-4 boards 1000, 1002 are used, and strips 210 are removed when 2-by-6 boards 1100, 1102 are used. Once the strips 208 or 210 are removed, the front surface 106 can be bent around both outside corners. This process is described below and shown in Figs. 12(a) - 12(c).
  • a removable strip 208 is held by a number of thin tags 1200 between the struts 206 parallel to the rear surface 108. To remove a strip 208, one need only break the thin tags 1200. The strip 208 is then removed in the direction of the arrow 1202 and discarded. The front surface 106 is then bent in the direction of the arrow 1204 to form a corner that will fit around one of the adjacent outside corners. It is to be understood that a similar but mirror-image process occurs with the second strip 208, so that the front surface 106 can be bent to form a second corner that will fit around the second of the juxtaposed outside corners. The strips 210 are removed in the same manner to permit the finishing device to be bent around two outside corners that are further apart.
  • the finishing device is attached to the framing board 1000 or 1102 by use of nails 1004 or 1104.
  • the attachment location of the device and the positions of the nails 1004, 1104 can be varied to enable the device to correct inaccuracies that may result from warped or mis-sized framing boards 1000, 1002, 1100, 1102 or inconsistencies in building practices. If necessary, shims may be placed behind the device before it is attached by nails 1004. 1104.

  • FIG. 14 shows a cross-sectional view of an alternative embodiment.
  • This embodiment provides only one set of removable strips 210 located equidistant from the center joint 100:
  • the number and complexity of the struts 206 has also been reduced to simplify manufacture of the device by plastic extrusion.
  • the arrangement of the distal struts 207 has also been changed for greater support to the tapered end 204 of the front surface of the device. If a portion of the rear flange 112 is drawn rearward to accommodate an uneven section in a rafter, the distal strut 207 will tend to allow the tapered front surface 204 of the device to maintain a straight edge in spite of irregularities in the underlying rafters. Assuming the device is molded from some type of flexible plastic, the end strut 205 will deform as necessary to accommodate such irregularities.

  • Drywall panels are conventionally supplied in predetermined widths, for example, and not meant to be inclusive, 3 ⁇ 8 inch, 1 ⁇ 2 inch, and 5 ⁇ 8 inch widths, etc. Rather than use a separate drywall corner finishing device for every predetermined thickness of drywall panel, one can use the embodiment of the drywall corner finishing device illustrated in Figures 23 through 25 to conform to any width of drywall panel, as shown in Figure 25.
  • Figure 25(a) illustrates the drywall corner finishing device in the resting position. When a' drywall panel 2500 is inserted into the space 114 between the edges 200, 202, as shown in Figure 25(b), the edges 200, 202 move apart, as illustrated by arrows 2306, to accommodate the width of the drywall panel 2500.
  • the expansion joint 2302 opens and the flexible joint 2300 adjusts to enable the distal portions 204 and 2304 to move apart as far as necessary to enable insertion of the edge of the drywall panel 2500.
  • This embodiment of the drywall corner finishing device can be used for drywall panels that are thicker than the thickness of the device.
  • the expansion joint 2302 maintains tension on the distal portions 204 and 2304, which aids in maintaining close contact between the drywall panel 2500 and the distal portions 204, 2304 of the drywall corner finishing device. It is to be understood that types of expansion joints 2302 other than that illustrated in Figs. 23 - 25 can be used in the present invention and that the present invention includes all types and designs of joints that provide the above-described expansion and tension.
