Abstract

A corner bracket of a side mirror for an automobile comprises an attaching member for accessory attaching, with a nearly triangular form, having an outer size sufficient to close an angle part formed between a door belt line and a slant pillar disposed on the upper side of the door belt line, and an attaching foot member extending from the attaching member to be fixed to the door body. The attaching member comprises an insert of U-like cross-section coated with high molecular weight elastic material, a glass-enclosing groove, and an attaching hole crossing the glass-enclosing groove. A cylindrical flash formed surrounding the attaching hole is molded having a weakened portion expected to be broken at one end and the weakened portion is cut during the mold releasing operation, whereby the removing work of the cylindrical flash becomes unnecessary after the mold releasing operation has been conducted. The outer circumferential surface of the engaging boss for attaching a blind plate is made to be a tapered surface, whereby the fear of breakage of the engaging boss during the mold releasing is decreased. Molding productivity can be improved in both cases.

Dependent claims

A corner bracket for an automobile side door of a door type which has an inside and an outside and a sector of spaced defined between a generally horizontal door belt line and a pillar which slants upwards from a juncture with the door belt line, whereby the sector of space has an included angle between the door belt line and the slanting pillar,

said corner bracket comprising:
an accessory-attaching member having a main portion of generally triangular form, for fully occupying said sector of space, from said juncture out to a given lateral distance from said juncture;
an attaching foot member extending laterally from said main portion of said accessory-attaching member and being provided with securement means for fixing said accessory-attaching member to an automobile side door;
said accessory-attaching member main portion comprising an insert having a U-shaped cross-sectional shape, said insert having a coating of high molecular weight elastic material, said main portion thereby including an inner side wall and an outer side wall, relative to an automobile, defining between them a groove, open at one end, for receiving a door glass;
means defining at least one pair of aligned openings transversally through said main portion, including one opening through said inner side wall of said insert and one opening through said outer side wall of said insert;
said coating of high molecular weight elastic material including an integral tubular flash based on one of said side walls within said groove and disposed so as to surround an axis passing between said aligned openings, thereby providing an axially extending inner peripheral wall;
said integral tubular flash terminating short of the other of said side walls in a free end, and having a free end portion located axially adjacent said free end, said free end portion being constituted by an axially short annular band in which said high molecular weight elastic material is abruptly thinner than within a main portion constituting a remainder of said integral tubular flash, said tubular flash remaining substantially unobstructed radially internally of said main portion thereof by said annular band.

a blind plate positioned in covering relation to at least a portion of said inner side wall of said main portion of said accessory-attaching member so as to cover the respective said one opening in said inner side wall and sealingly engage said free end of said sealing lip;
and
means attaching said blind plate to said inner side wall of said main portion of said accessory-attaching member.
