Abstract: A drywall corner piece with flange surfaces forming a near right angle forming a cup for fitting over drywall corners where the web sections of the flanges have at least one strain relief channel allowing the piece to flex to different angles.

Abstract: A boxable drywall corner trim including an elongated semi-rigid member that forms a pair of flanges joined at a grooved hinge along a centerline. Each of the flanges can have a thinner part and a thicker part joined at a step that is approximately parallel to the centerline a predetermined distance from the centerline. The thicker part of the flanges can form a protruding nose member that makes the piece boxable by preventing the cross-over of wet drywall mastic or mud from one flange to the other. The thinner portion of the flange may optionally be perforated with a pattern of punched holes of any configuration throughout the flange assembly. The piece can have a wall-facing paper or other fibrous layer of material that has a tacky adhesive on its wall-facing side. The adhesive can be in a pattern of dots, ridges, lines or any other pattern, or the adhesive can be continuously coated on the surface.

Abstract: A notched drywall trim piece that can take the form of a bead, hinged trim piece or bullnose piece that generally is constructed from a semi-rigid core that forms two flanges. At least one of the flanges is notched allowing the piece to follow the shape of an arch or arbitrarily curved corner. The product can generally be installed without any mechanical fasteners since the inner or wall-facing surface of the product is prepared or treated to bond directly with drywall mud or other mastic. In this manner, the piece can be installed using only wet mud or other mastic. The installation process can be aided by the used of a corner roller common in the industry to help set and align the material with the corner being trimmed. The outer or room-facing surface can optionally be treated or prepared to bond with the mud or can be prepared to directly receive paint or texture.

Abstract: A drywall or sheet rock edge clip device that can hold joints of drywall together at the apex of vaulted ceilings or at any other drywall seam at any angle. The device can include tabs and a head or cross member coupled by a stem that fits through the seam or joint and pulls and holds it together. A wire-tie version of the invention can have serrations along the stem and pull up and tighten like a wire-tie. The unused tail section can be broken off by bending it from side to side.

Abstract: A drywall tool for dispensing flexible trim material such as FLEXTRIM and ULTRALITE products, or any other flexible trim material, containing a head attached to an elongated handle, a drive wheel attached to the head for pulling the trim material from a roll, at least one roller for pressing the trim material into an interior or exterior corner and a cutter for cutting the trim material. A pair of rollers can be attached to a ferris wheel assembly to be swung into position for interior or exterior corners. The interior roller can resemble a pizza knife, and the exterior roller can be cylindrical of varying diameter shaped like two intersecting cones.

Abstract: A drywall hopper assembly that contains a double blade that can apply drywall mud to both interior and exterior drywall corners with no blade change. A zigzag blade can contain two grooves, one for interior corners and one for exterior corners. With this blade arrangement, an operator can quickly move from one type of corner to another without using multiple tools, multiple blades or hand application methods to apply mud. The present invention can contain a pliable release port to present mud equally to an interior or an exterior corner. There can be such a port on both the top and bottom of the blade so that mud is smoothly applied as trim moves through the hopper or the hopper is moved along the trim.

Abstract: A drywall trim application device that can hold a large role of drywall flex corner trim material and, as the material is being dispensed, pre-crease or form the material for use on an inside or outside corner, or any angle within the range of the trim material, apply a mastic material (drywall mud, adhesive or any other bonding medium) to the flex trim material, and cut the material at any desired length automatically. Measurements may be either input by hand or down loaded from an electronic measurement tool into this device. This invention can generally store multiple measurements such as length and angles, measure the length of flex trim material as it is dispensed from the device, crease the material, apply predetermined amount of mastic, and automatically cut the flex trim material to each length previously input.

Abstract: A power cutter tool for applying drywall tape or trim that contains a powered blade that can cut the tape or trim material by simply pressing a trigger. The cutter can be powered by a spring or springs, a motor, hydraulically or by any other means. The trigger can be a button, lever, valve or any other means for releasing a powered blade.

Abstract: A drywall mastic applicator or nail spotter that includes a mastic box with an open end and a plunger the fits into the open end that effectively seals it. The box can have a hole or other opening in another surface opposite the plunger so that when the plunger is depressed, the mastic exits the hole. A blade containing at least one groove can be mounted near the hole so that the mastic is applied as an exact bead. The blade can contain several grooves to produce a sting of beads. This arrangement speeds up taping and finishing drywall by applying an exact amount of mastic in the right place in the form of a bead.

Abstract: A drywall corner bead made of high-impact plastic or other material that can be in-elastically bent to any angle at the bead itself. The corner bead can have a front layer of paper or other material capable of directly receiving paint or texture and an optional backing layer of paper or other fibrous material. The bead can be bent and re-bent inelastically as many times as needed to fit a corner.

Abstract: A drywall finishing system for finishing normal inside and outside corners of any angle. The finishing system comprises a preformed trim piece comprising a semi-rigid member that is relatively thick in the center and tapers laterally to a thin edge or is stepped forming a thick and thin portion. A layer of fibrous can be bonded to the inside surface of the semi-rigid member for receiving joint compound to continuously bond the trim piece to the dry wall. A layer of finishing material can be bonded to the exterior surface of the semi-rigid member. The finishing system can be attached to a wall with fasteners such as nails.

Abstract: A cable tie with side notches on either one or both sides that allows breaking off the unused end after pulling the tie tight eliminating the need for using a tool to trim the ends off the cable tie. The strap is pulled normally when tightening the cable tie around wires, cables, hoses, tubes or other items in a bundle and then pulled sideways to cause the strap to break off leaving no sharp edges.

Abstract: A boxable corner bead for finishing drywall corners that is made from two flanges with a protruding nose section. This bead can be made in regular, bullnose, or flex trim type arrangements. Once the bead is attached to a drywall corner, it can be mudded on both sides of the corner without waiting for the mud on the first side to dry. This is because of the shape of the nose which allows a mud dispensing box to apply mud on one side without getting mud on the nose. The box can then be immediately moved to the other side, where that side can be mudded. The nose itself is prepared to directly receive paint or texture, and hence does not need any mud. A version of the device has a raised trapezoidal, triangular or bull-nose section with a V-groove cut in the back. The bead hinges around the V-groove to match any corner angle. Both sides can be mudded as with the fixed bead. The beads can be used with both interior and exterior corners.

Abstract: A drywall finishing system for finishing 1) normal inside and outside corners of any angle, 2) stub wall or closet corners, 3) window wrap corners, and 4) L-metal for window sills and areas where drywall ends against some other surface like brick. The finishing system comprises a preformed trim piece comprising a semi-rigid member that is relatively thick in the center and tapers laterally to a thin edge. A layer of paper is bonded to the inside surface of the semi-rigid member for receiving joint compound to continuously bond the trim piece to the dry wall; this paper layer can optionally have a layer of adhesive material on its outer surface. A layer of finishing material is bonded to the exterior surface of the semi-rigid member.
