MASKING MEMBER
BACKGROUND OF T~E INVENTION
The present invention relates to a masking member which protects a part of an article from a surface treatment such as coating, plating, vacuum evaporation, phosphatizing, and the like. More particularly, the present invention relates to a masking member consisting of an upper wall and a pair of side walls which extend from both sides of said upper wall wherein said masking member is made of an elastic material, and narrow width part(s) is~are) formed between said pair of side walls. When a surface treatment is effected on the surface of an article, and if said surface of said article has part(s) on which said surface treatment should not be effected for the reason that another surface trea-tment is effected on saicl part(s) after said surface treatment or said surface treatment spoils the appearance of said article and so on, said part(s) of said surface of said article may be covered and protected with said masking member.
ESCRIP~ION OF THE PRIOR .ART
Hitherto, adhesive tape has been used as a masking member to protect a pillar, frame, and the like. Namely, the adhesive tape is wound round said pillar, frame, and the like to protect them from said surface treatment and after said surface treatment, said adhesive tape is removed from said pillar, frame, and the like. Said pillar, frame, and the like may be not effected by said surface treatment since said pillar,`frame, and the like were covered with said adhesive tape during said surface treatment.
Nevertheless, adhesive tape as a masking member has faults in that attaching and removing of the adhesive tape to/from a pillar, frame, and the like take time and have a high labor cost, and further, the adhesive tape wound round a pillar, frame, and the like is buried in the layer of said surface treatment and it is very difficult to find the outer end of said buried adhesive tape to remove said adhesive tape. Said faults of adhesive tape may seriously obstruct a mass-production line such as a coating line for automobiles.

DETAILED DESCRIPTION
FIG~ 1 to FIG. 6 relate to a first embodiment of the present invention. Referring now to FIG. 1 to FIG. 6, a masking membert103) consists of an upper wall(103A), a pai~
of side walls~1o3B)r(lo3B) which extend from both sides of said upper wall(103A~, and a pair of flanges(103C~,tlO3C~
which respectively extend from the edges of said side wall~
~ .
2~`3~3~al (103B),(103B) and an open part~103D) is formed between the edges of said side walls(103B),(103B). The width between said pair of walls(103B),(103B) of said masking member(103) gradually decreases as the width approaches said open part(103D) of said masking member(103) so that a narrow width part(103E) is formed at said open part(103D) of said mask-ing member(103). Further, cutting lines(103F),(103G) are formed on bending parts of said masking member(103).
As shown in FIGs. 2, 3 and 4, said masking member(103) is attached on the frame(101A) of a door(101) of an automobile by placing said frame(101A) between said pair of side walls(103B),(103B) before coating and said masking member (103) is fixed by the elasticity thereof at the narrow width part(103E) of said masking member(103), and then said door (101) is coated by spraying a colored paint(102A) thereon.
Said frame(101A) of said door(101) is not coated with said colored paint since said frame(101A) is protected by said masking member(103).
After coating, said masking member(103) is removed from said frame(101A) and said frame(101) is coated by spraying another colored paint(102B) thereon. When said frame(101A) is coated the lower half(101B) of said door(101) is covered with a sheet such as paper and ~he like. As the result, said door(101) is coated with two kinds of paint(102A),~102~) having a different color respectively as shown in FIG. 6.
~IG. 7 to FIG. 11 relate to a second embodiment of the present invention. Referring now to FIG. 7 to FIG. 11, a masking member(203) consists of three divided masking members(204), (205), and (206). As shown in FIGs~ 7, 8 and 9, each divided masking member~204), (205) and (206) consist of an upper wall(204A), (205A) and (206A), a pair of side walls(204B~,(204B), (205B),(205B) and (206B),(206B) which extend from both sides of said upper wall(204A), (205A) and (206A), and a pair o~ flanges(204C),(204C), (205C),(205C), and (206C),~206C) which respectively extend .. . :
. , ~'.
from the edges of said side wall~204B),(204B), (205B),(205B), and (206Bl,(206B). The width between said pair of side walls(204B),(204B), (205B),(205B), and (206B),(206B) of each divided masking member(204), (205) and (206) gradually increases as the width approaches said open part(204D), (205D) and (206D) of each said divided masking member(204), (205) and (206) and an open part(204D), (205D) and (206D) is formed between the edges of said walls(204B),(204B), (205B),(205B) and t206B),(206B). Further, ribs(204F),(204F), (205F),(205F), and (206F),(206F) are formed on the insides of said pair of side walls(204B),(204B), (205B),(205B), and (206B),(206B) so that a narrow width part(204E), (205E) and (206E) is formed between said ribs(204F),(204F), (205F), (205F) and (206F),(206F) of said side walls(204B),(204B), (205B),(205B) and (206B),(206B).
Each said divided masking member(204), (205) and ~206) is respectively attached on the frame(201A) of a door(201) of an automobile as shown in FIG. 10 and as the result, said frame(201A) is protected by a ~asking member~203) consist-ing of three divided masking members~204), (205) and (206) and the end of each said divid~3d masking member(204), (205) and (206) is overlapped respectively at the joint between each said divided masking member(204) and (205), and each said divided masking member(205) and (206).
Each divided masking membe?(204), (205) and (206) is fixed by elasticity thereof at the narrow width part(204E), (205E), and (206E~, wherein said ribs(204F),(204F), (205F),(205F), and (206F),(206F), respectively engage the back side of said frame(201A).
In the second embodiment, a two-color coating is effected on said door(201) the same as the first embodiment.
The masking member of the present invention is made of an elastic material such as from plastics such as polystyrene, polyethylene, polypropylene, polyvinylchloride) polyurethane, .

melamine resin, urea resin and the like; plastic foams of said plastics; laminated material of said plastic foams and said plastics; fiber materials such as fabric, knitting, non-woven fabric, paper, corrugated card-board and the like;
thermoplastic resin - impregnated fiber material; thermo-setting resin - impregnated fiber material; wooden board such as wood board, hardboard, plywood and the like; metal and the like; and the masking member of the present invention may be produced by vacuum forming, press, extrusion, injection molding, and the like.
In case that said masking member is made of plastics, it is desirable to mix inorganic filler such as calcium carbonate, talc, bentonite, stone powder, blast furnace slag, flyash, and the like in said plastics since heat resistance, mechanical properties and the like of said masking member are improved by said inorganic filler and further, when used masking member is burnt in the combustion furnace, smaller combustion energy is procluced so that said combustion furnace stands long use. ~suall~, 10 to 500 weight parts, desirably 20 to 400 weight parts of said inorganic fillar is mixed in said plastics.
Polyolefin such as polyethylene, polypropylene and the like is desirable plastics for the material of maskin~ member o~ the present invention since said polyolefin has high solvent resistance and is inexpensive, and of course, poly-olefin in which said inorganic filler is mixed is desirable material of said masking member.
Polystyrene foam is also desirable material of said masking member since said polystyrene foam is light and inexpensive nevertheless since said polystyrene foam has low solvent resistance and low heat resistance, it is desirable to laminate a suitable plastic on said polystyrene foam.
