  • Patent number: 9750387
    Abstract: A selectively attachable buffer pad for using as an attachment to a conventional drill to buff or polish surfaces includes an attachment member which defines an elongated, rigid shank which is sized and shaped to be secured in the chuck of a conventional drill, a padded layer defining a planar body with a circular shape which is constructed out of a deformable material, and a buffer layer defining a conventional soft fiber buffing pad. Advantageously, the deformable nature of the padded layer enables selectively attachable buffer pad to transfer rotation from the attachment member to the buffer layer while also providing shock absorption. Thus, a conventional drill which is not otherwise suit for buffing or polishing is configured to accomplish the same through its attachment to the selectively attachable buffer pad.

  • Publication number: 20150067976
    Abstract: A panel cleaning roller assembly capable of comprehensively wiping a panel has an axle serving as a rotating body, and a roller serving as a wiping body. The roller is wound around and rotated synchronously with the axle. The roller has a wiping surface having longitudinally curved grooves, transversally curved grooves and wiping grains formed between the longitudinally and transversally curved grooves. The wiping grains are arranged in a curved matrix. Thus, the axle may be utilized to rotate the roller relatively to the panel to perform the rotating wiping and absorb the foreign object or debris to the longitudinally and transversally curved grooves of the roller, thereby preventing the surface of the panel from being scratched. Thus, the comprehensive wiping can be performed without forming any gap, thereby significantly enhancing the cleaning efficiency and quality and effectively enhancing the utility.

    Abstract: Disclosed is a paint roller device comprising an inner hub and an outer hub spaced by a cage of wires and adapted for supporting a paint roll sleeve. A cylindrical retainer extends axially outwardly from the outer hub and is adapted to retain a ball therein, the cylindrical retainer being spaced radially inwardly from the periphery of the outer hub to define a gap between an inside surface of the paint roll sleeve when on the roller. The end of the paint roll sleeve on the paint roller device and an end of the retainer define a plane perpendicular to an axis of the roller, and at least a portion of the ball extends a predetermined distance axially outwardly from the plane. The gap between the sleeve and the cylindrical extension prevents paint from interfering with the ball.

The drive plate includes a stiff disk element and tongue-like tabs connected flexibly to a radially outer portion or rim of the disk element, and extending radially inwardly toward a radially inner portion or hub of the disk element. The radially inner free ends of the tongue-like tabs are free to flexibly deflect away from the plane of the disk element. The pad is mounted on the tabs and on the radially outer portion of the disk element. During rotational operation of the floor care disk, due to the arising centrifugal force acting on the center of mass of the rotating pad and tongue-like tabs, the pad and the tongue-like tabs are flexibly deflected away from the disk element and toward the floor surface, thereby deflecting the pad into osculating contact with the floor surface.

    Abstract: An apparatus and method for picking up stickers in grassy or other ground areas. A roller is rotatably mounted on a frame and a stretchable fabric is removably mounted and stretched on an outer surface of the roller. The fabric is of a construction and thickness to pick up stickers as the roller is moved by the frame and rotated in engagement with a grassy or other ground surface. When the fabric is full of stickers, it is removed from the roller and replaced with a new unused stretchable fabric that is removably mounted on the roller.

  • Patent number: 8146194
    Abstract: The present invention is a buffer device that is designed and configured to successfully and adequately buff and polish any desired surface without causing fatigue for the user, as well as without creating any swirl marks. In order to provide for such a product, the present invention comprises a frame having a cylindrical body secured thereto. A motor is coupled to the cylindrical body to provide for the body to rotate about a normally horizontal axis that is parallel to the desired surface to be buffed, polished, and cleaned or the like. Secured to the cylindrical body is a buffing/cleaning pad fabricated from a conventional material.

  • Patent number: 8117709
    Abstract: A rotary buffing and finishing system includes a polymeric foam cushioning layer that has a graded compression load deflection which is interposed between a backing plate and a relatively thin performance layer that is removably attached to the foam cushioning layer. The backing plate is flexible but has a compression load deflection greater than the cushioning layer, and the cushioning layer includes two foam layers of graded compression load deflection that decreases from a rear face to a front face. The system provides improved performance over thicker and more expensive performance layers while reducing operator fatigue.

  • Patent number: 8082618
    Abstract: A cloth-type vehicle laundering implement includes a support mechanism consisting of a rotatable drive shaft and a plurality of generally parallel, adjacently arranged spacers mounted on the support mechanism. Each of the plurality of spacers includes a first face and a second face. The implement includes a plurality of individual circular fabric disk elements disposed between the first face of one of the plurality of spacers and the second face of another of the plurality of spacers. Each of the plurality of individual circular fabric disk elements extends outwardly beyond the spacers. Each of the individual circular fabric disk elements consists of a single piece of non-woven material having an inner diameter and an outer diameter. The inner diameter is retained in a single plane by a securing mechanism such that more material is located adjacent the inner diameter than the outer diameter to provide a more rigid element.

  • Publication number: 20110189927
    Abstract: A composite pad includes an outer pad portion having a surface with a firmness, stiffness or abrasiveness, and an inner pad portion disposed on or in the outer pad portion, the inner pad portion having a surface with a firmness, stiffness or abrasiveness which is greater than that of the outer pad surface. The backside of the composite pad preferably includes a hook-and-loop or other mechanism for attachment to a tool such as an orbital polisher. The inner portion may used to remove larger scratches left from sand paper (or other abrasives) then, without removing the pad, the polisher tool may be tilted relative to the surface enabling the outer portion to buff the area and remove any swirl marks. The surface of the inner pad may be raised relative to the surface of the outer pad, flush or recessed. In the preferred embodiments the various pad portions are made of foam material such as polyurethane.

  • Patent number: 7906051
    Abstract: Selected surfaces of a cellular polymeric foam surface finishing pad are heated to cause the surface cells to partially collapse or to fully collapse and glaze over. The selected surfaces may be the planar pad faces or may be formed in one or more depressions formed in the planar faces. The areas of partially collapsed cell structures in the operating face of the pad provide a slow down in the rate of polish or compound absorption, increasing the effectiveness of the finishing process. The fully collapsed cell glazed surface on the rear attachment face of the pad prevents the migration of moisture through the pad to the pad attachment mechanism.

  • Publication number: 20100210435
    Abstract: A composite paint roller is provided for improving ease of cleaning, manufacture and adaptability of the same. The roller comprises an elongate cylindrical core, a sheath, and first and second end caps. The sheath is removably mountable about and frictionally engageable to the core. The core defines a core length and opposing open ends. The sheath defines an axial length and opposing sheath ends. The axial length of the sheath is greater than the core length with the opposing sheath ends being foldable and axially insertable into the opposing open ends to produce a radial compression of the sheath adjacent the opposing open ends. The radial compression creates opposing beveled ends of the roller. The first and second end caps each are attachable to the opposing open ends to secure the opposing sheath ends within the opposing open ends.
