Definitions
- the present invention relates to a new masking member used to protect the inside and circumference of a hole of an article from a surface treatment such as coating.
- a masking member produced by the moulding of a plastic sheet or plastic foam sheet such as polyethylene sheet, polypropylene sheet, polystyrene sheet and the like in a vessel shape has been provided such as in Japanese application Jikkai Sho No. 62-202384, as shown in Fig. 3.
- Said masking member (11) comprises an inserting part (12) and a flange (13) and said masking member (11) is inserted into a hole (15) of an article (14) to protect said hole (15) from a surface treatment.
- Said masking member (11) is removed by sticking a hook (17) into the side of the flange (13) after said surface treatment, but if said masking member (11) is inaccurately stuck into by said hook (17), it is possible that said masking member (11) will not be removed correctly.
- said masking member (11) is made of a thin plastic film, said masking member (11) is apt to deform when said masking member (11) is stuck into by the hook (17) and it is difficult to accurately stick said hook (17) into said masking member (11).
- a robot equipped with said hook (17) is used to remove said masking member (11) the above described disadvantage may be a very significant problem.
- the present invention provides a masking member for masking a hole comprising an inserting part to be inserted in said hole and a flange extending from an end of said inserting part characterised by a rim extending at least partly around said flange.
- the masking member may have a vessel shape and may be formed from a sheet.
- the rim may be used when the masking member is removed by a tool.
- At least part of the edge of said flange is folded thereby forming said rim.
- An extending part of said flange may be shaped such that it extends away from the surface in which said hole is located when said masking member is inserted in said hole and the outer surface of said extending part may be corrugated.
- Fig. 1 is a perspective view of the masking member.
- Fig. 2 is a side sectional view illustrating the removing of the masking member with the hook.
- Fig. 3 is a side sectional view illustrating the removal of the masking member with the hook in the prior art.
- a masking member (1) comprises an inserting part (2) having a vessel shape and a flange (3) extending from the end of said inserting part (2) wherein a cross-rib (21) is formed in the bottom surface of said inserting part (2) for reinforcement and a corrugated surface (31) is formed on the outer surface of said flange part (3) and further, a rim (32) is formed by the upper edge (32) of said flange being folded.
- a masking member (1) is attached in a hole (5) of an article (4) by inserting said inserting part (2) into said hole (5) and after a surface treatment (6), said masking member (1) is removed by hooking said folded edge of said flange of said masking member (1) with a hook (7) and the like. Said hook may or may not also stick into the side of the flange.
- said masking member (1) is removed by using said hook (7) as above described, the deformation of said masking member (1) is suppressed by the rib-effect of said corrugated surface (31) of said flange and said masking member (1) is removed effectively by using said hook (7).
- the surface treatment may for instance be painting or priming or the application of a protective coating for instance, on the underside of a car body where the holes are to be kept clear of the protective coating to make the subsequent use of the holes, e.g. for fixing fully accurate.
- Said masking member (1) may be produced from a sheet, preferably by vacuum forming, and the sheet is preferably of a thermoplastic resin or is a sheet of a foamed thermoplastic resin such as polystyrene, polyethylene, polypropylene and the like.
- the member could be formed by the moulding of a fibre material such as pulp, polyamide fibre, polyester fibre, acrylic fibre, acetate fibre and the like wherein said fibre is bound by a binder such as melamine resin, urea resin, phenol resin and the like.
- an inorganic filler such as calcium carbonate, calcium sulfate, calcium phosphate, bentonite, talc, blast furnace slag may be mixed into the material of said masking member of the present invention.
- the masking member of the present invention is removed effectively with a hook and the like. Accordingly, the automatic removal by a robot can be easily applied to the masking member of the present invention.
