A pre-formed insert body

摘要

A body 1 defining an aperture to be formed in a panel 12, comprises an inner surface 4,8 an outer surface 5, 14 a front face 17, 20 and a rear face 7, 27. The aperture to be formed is of a varied geometry (such as a reduced size or altered shape) relative to an existing aperture 9 through a panel 12. The inner surface 4, 8 provides for an inner side wall of the aperture to be formed. The panel has a thickness defined between a first face 11 and a second face 12, and an existing aperture side wall as defined by the existing aperture 9 and extending between the first and second faces of the panel . The outer surface 5, 14 comprises an outer side wall of the, or at least a part of the, aperture to be formed and/or of the existing aperture 9 to be varied in geometry. The outer side wall is, at least in part, located substantially adjacent to the existing aperture side wall. The rear face 7, 27 provides for at least one support surface to be located upon a region of the second face 12 of the panel surrounding the existing aperture. The inner side wall terminates with at least one rim on the front face 6. The front face 6 comprises one or more recessed regions 17, 20. Each rim has a rim surface 16, 18, 19. The rim surface 16, 18, 19 is a surface projected from at least one of the one or more recessed regions so as to provide a reference surface, referenced relative to the first face 11 of the panel. The rim surface is substantially planar with the first face of the panel. The front face comprises a plurality of associated recessed regions each having an associated rim. Each rim has an associated rim surface. Each associated rim surfaces projects from a respective associated recessed region. Each rim is associated at least in part with an associated inner side wall or a part of an inner side wall. One or more of the plurality of associated recessed regions and/or the associated rim, or an associated recessed region and an associated rim, is/are separately connectable to or disconnectable from the body. The recessed region is a surface recessed from the first face of the panel and recessed relative to the rim surface, when the rear face is located upon the second face of the panel. Each said recessed region is receivable of a quantity of applied material thereon sufficient to fill the recessed region and provide for a built-up surface that is substantially level or planar with said rim surface.
