  • Patent number: 7740524
    Abstract: A sanding tool for sanding drywall corner joints is provided. The tool has an elongated mounting plate with a swivel handle attached to one side, and to the other side is attached one or more circular sanding disk holders to which disks of sanding medium are removably attached to a flat face of the sanding disk holder. The sanding disk holders are rotatably mounted on short axles attached to the mounting plate, and are each configured having a relatively wide edge that frictionally engages a wall adjacent the wall being sanded. This causes the sanding disk holder to rotate, sanding the drywall joint with a rotary motion instead of a linear motion.
    Type: Grant

    Abstract: A sanding tool for sanding sheetrock corner joints is provided. The tool has an elongated mounting plate with a swivel handle attached to one side, and to the other side is attached one or more circular sanding disk holders to which disks of sanding medium are removably attached to a flat face of the sanding disk holder. The sanding disk holders are rotatably mounted on short axles attached to the mounting plate, and are each configured having a relatively wide edge that frictionally engages a wall adjacent the wall being sanded. This causes the sanding disk holder to rotate, sanding the sheetrock joint with a rotary motion instead of a linear motion.

  • Patent number: 7101136
    Abstract: Apparatus for lifting and transporting drywall panels has a pair of panel-supporting legs of square tubing attachable to side rails of a lift platform. Each leg is connected to the rails by an upper bracket at the top of the leg and a lower bracket at a middle location. A panel-receiving U-shaped channel is located on the opposite side of the legs, away from the rails. The lower bracket has a standoff member projecting the bottom of the leg outward at an angle. A roller at the base of the channel provides low-friction rolling contact with an inserted panel, and a groove in this roller serves to guide the panel. Rollers at the tops of the legs and elsewhere are placed to keep panels from being damaged by contact with the legs.

  • Patent number: 6511275
    Abstract: Apparatus for lifting and transporting drywall panels on a lift platform has a pair of panel-supporting legs of square metal tubing attachable to side rails of a lift platform. Each of the legs is connected to the rails by an upper clamp at the top of the leg and a lower clamp at a middle location. A panel-receiving U-shaped channel is located on the opposite side of the leg, away from the rails. The lower clamp has a standoff member included in its connection to the leg, which serves to project the bottom of the legs outward at an angle. Rollers at the top and bottom of the legs provide low-friction rolling contact for weight bearing surfaces, and other rollers are placed to keep panels away from contacting the legs or other surfaces.
