Definitions

  • the present invention relates to the field of devices for sandpapering surfaces of any type.
  • sheets are used to sandpaper surfaces, one of the surfaces of which comprises abrasive materials that perform the necessary smoothing action.
  • the blocks are made of rigid material so as to offer the operator a solid hold and at the same time provide a valid support for the abrasive sheets that are normally applied to the blocks using means such as Velcro®, which allow easily removable coupling thereof simply by tearing off, or smooth supports of various kinds through adhesive gripping.
  • the working surface of the block i.e. the one to which the abrasive sheet is applied
  • the working surface of the block is flat, although blocks in which said surface is concave or convex are also known, in order to be able to work on surfaces with rounded shapes, such as in the case of car body surfaces.
  • a block comprising a main body provided with a plurality of longitudinal and/or transverse cuts, such as to allow mutual partial detachment of the adjacent segments formed by said cuts, while allowing them to remain connected to the base of said main body.
  • the present invention allows the aforesaid problems to be solved through a block comprising a main body 10, in turn comprising:
  • Said main body 10 further comprises a series of cuts 12, longitudinal and/or transverse, having a depth such as to allow mutual partial detachment of the adjacent segments formed by said cuts, while allowing them to remain connected to the base of said main body 10 or, at least, to said reversible adhesive means present on the lower surface and on the optional side surfaces thereof.
  • Said longitudinal and/or transverse cuts allow the upper part of said main body 10 - the part in contact with the user - to be separated into segments of smaller dimensions adapted to be partially distanced from one another during use so as to deform said main body 10 and the lower surface thereof, in such a manner as to allow improved adhesion to the surfaces to be smoothed in the case in which they are not flat.
  • the body 10 is made of mechanically resistant, flexible and elastic material.
  • the upper surface can be ergonomically shaped and be provided with appropriate shaping 11 such as to facilitate holding and gripping thereof by the user.
  • the block according to the invention can be marketed in the form of a kit comprising shapes of different form and size and optionally one or more sheets or disks of abrasive material (optionally with different grit sizes to one another).
  • the block according to the invention allows immediate adaptation of the smoothing means to surfaces having any contour.
  • the cuts made in the main body allow the segments to spread apart, thereby allowing the continuous surface of the block to take the desired curve (so as to adapt to that of the surface to be smoothed) through simple pressure exerted by the operator.
