Abstract
The invention pertains to electric horns for automobiles wherein a metal horn motor housing is assembled to a sound projector formed of synthetic plastic. A metal insert is molded into the projector having a metal flange extending from the projector adjacent a projector mounting surface whereby the insert flange is deformed upon the motor housing to produce an effective mechanical interconnection and assembly of the motor housing and projector.
Claims6
As an article of manufacture, a molded synthetic plastic electric horn projector having an annular planar surface defined thereon for mounting the projector upon a motor subassembly having a flange portion, a metal insert integrally molded into the material of said projector, and a deformable metal flange of annular configuration defined upon said insert surrounding said mounting surface and projecting from said projector configuration adjacent said mounting surface intersecting the plane of said mounting surface and extending therebeyond for deformation upon the subassembly flange portion.
In an electric horn including a motor housing having a flange defining a periphery and a flat projector mounting surface, a projector mounted upon the flange mounting surface having a sound passage for emitting sound, said projector being of a molded construction formed of a synthetic plastic material having a mounting surface in opposed relationship to the motor housing flange projector mounting surface, the improvement comprising, a metal insert integrally molded into the plastic projector material having a deformable portion projecting from the configuration of the projector adjacent the mounting surface of the projector, said deformable portion being deformed upon the motor housing flange over the periphery thereof to maintain the motor housing and projector in assembled relation.
