  • Patent number: 11033167
    Abstract: A toilet cleaner, including a head and a handle for clamping the head. The handle includes a housing, a manipulation component, and a clamping jaw. A clamping end of the housing is provided with a first clamping head and is hinged to a middle portion of the clamping jaw. The manipulation component is fitted in the housing and includes a handling portion at a grip end of the housing. An outer end of the clamping jaw has a second clamping head corresponding to the first clamping head, and the manipulation component is connected to an inner end of the clamping jaw, so that the first clamping head and the second clamping head are matched with each other. The present invention is more firm and reliable with better compatibility, so that the handle can conveniently and reliably clamp the heads in different thicknesses, or of various brands, forms or specifications.

  • Patent number: 8231440
    Abstract: A sanding block for supporting an exteriorly mounted looped sanding belt having an elongated and planar shaped base. A planar shaped cover exhibits first and second oblique extending surfaces and, upon engaging with the base by a plurality of mating tabs and slots, collectively defines a three-dimensional article for supporting thereupon the looped sanding belt. A trigger exhibits a three-dimensional rectangular shape and extends laterally across a widthwise defined opening in the base in communicating fashion with an end surface associated with the cover, such that the trigger is positioned between the base and cover. The trigger is displaced in a first lateral direction to lengthwise displace the cover away from the base, the trigger displacing in a second and opposite lateral direction to reverse displace the cover inwardly towards the base.

  • Publication number: 20100167630
    Abstract: An abrasive disc includes a backing layer on a first major surface, a water-impermeable abrasive layer on a second major surface, and a water-absorbable, compressible, resilient, porous foam layer sandwiched in between the backing layer and the abrasive layer. The disc further includes a plurality of perforations. The disc is used to abrade a surface. Fluid is absorbed into the abrasive disc. The fluid is then released to the surface by compressing the abrasive disc against the surface in an abrading motion. The fluid is allowed to mix with and absorb surface swarf; and compression on the abrasive disc is released, reabsorbing the fluid and trapping swarf inside the disc.

  • Patent number: 7192338
    Abstract: A tool for co-operating with a fixing device wherein the tool comprises a tool body in the form of a circular disk, with a central opening and a radially inwardly facing locking surface. The fixing device comprises at least one radially outwardly facing projection of a locking element, which can be actuated manually and with which the fixing device can be releasably connected to the tool. In the locking position the at least one radially outwardly facing projection of the fixing device engages over the inwardly facing locking surface of the tool. The tool body is axially secured and held non-rotatably relative to the fixing device. The at least one radially outwardly facing projection of the fixing device and a support for the tool are arranged axially displaceably relative to each other, wherein the axial displacement travel is blockable by a centrifugal force device.

  • Patent number: 6663479
    Abstract: A hand held tool using continuous sanding belts for sanding and smoothing flat surfaces with the additional capability to produce more uniformly rounded edges and corners of various work pieces. Its two piece construction comprises a flat base plate rotationally attached to the bottom side of a housing. The housing has along the length of its top side a deep channel into which a portion of a mounted sanding belt may be wedged, creating a concave sanding surface, that can then be used to produce more uniformly rounded edges and corners. The housing is made of a resilient, compressible material, while the base plate is of a rigid structure. The tool incorporates a way for placing and tensioning continuous sanding belts on it by simply swiveling the base plate that is attached to the bottom of the housing, which by such rotational positioning compresses the compressible material of the housing, or releases it, thus applying or releasing tension on a mounted belt.
