    Abstract: A sanding block for sanding high and extended surfaces configured for use in combination with an attached pole. The sanding block is round in shape and is rotationally mounted on a pole mount that interfaces between the sanding block and the pole, which attaches to a rotatable hub of the pole mount. This allows the sanding block to rotate during use and the pole to be rotated to different angles in relation to the flat working surface of the sanding block. Adjacent surface marring is prevented by the rotation of the sanding block upon contact of a side edge with such an adjacent surface. Optionally the pole mount can be locked to prevent rotation if desired and a barrel can provide an interface between the pole and the pole mount. This barrel can be straight, angled, or adjustable for angle, in the different preferred embodiments.

  • Patent number: 7775855
    Abstract: A hand-held, manually-operated sanding tool includes a base body, a handle, and a coupling device. The base body defines an aperture extending from a first surface of the base body to a second surface of the base body. The handle includes a grip and a post. The coupling device is coupled with the post of the handle through the aperture. The handle and the coupling device are positioned near opposite surfaces of the base body to rotatably couple the handle to the base body such that the handle is rotatable about an axis defined by the post.

  • Publication number: 20100178849
    Abstract: A system, apparatus and method capable of grinding and polishing fabricated vertical surfaces of varying shapes and sizes without the use of hand tools. The system comprises a frame which can be affixed to the surface and which supports a grinding and polishing apparatus. The grinding and polishing apparatus uses air pressure to force a rotating grinding or polishing disc against the surface being worked on. The frame is designed so that the grinding and polishing apparatus can be moved (via, e.g., tracking) both vertically and horizontally to any desired point within the frame. The grinding and polishing apparatus optionally includes a water nozzle and vacuum system to spray and recapture water used to cool the surface being operated on.

  • 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.

  • Patent number: 7722435
    Abstract: A sander can include a housing, an indicator disposed on the housing, and a motor assembly in the housing. The motor assembly can include an output member. A platen can be driven by the output member. A sensor assembly can be configured to sense a condition in which a pressing force in excess of a predetermined force is applied to the sander in a direction normal to the platen and generate a sensor signal in response thereto. A controller can receive the sensor signal from the sensor assembly and control operation of the indicator in response thereto. The sensor assembly can include a force sensing resistor. The force sensing resistor can be disposed adjacent to a gripping portion of the power sanding tool. The indicator can include at least one light source. The controller can illuminate the light source according to a schedule.

  • Patent number: 7632174
    Abstract: A sander comprises a body member molded of polypropylene to which a soft pad member is integrally molded or directly bonded thereto. Preferably, the material comprising the pad member is of a thermoplastic elastomer material, such as Santoprene®. Significantly, when the pad member is molded directly to the body member, the pad has internal dimensions only slightly larger than the external dimensions of the body member so that, when the body member is located within the confines of the pad member, a secure fit is formed between these two members, without any space between them. Further, the respective dimensions of the body member and pad member give the sander a thick, one-piece appearance in side and end views. The pad member may also include a plurality of openings which help provide a “spongy” effect to the user, smoothing the peaks and reaching the valleys of an uneven surface upon which the sander is utilized.
