Abstract
A line guide device for fishing rods includes an annular holder for holding a line guide ring, which is defined by a metallic annulus and provided with a peripheral groove and an outer ring defined by a metallic annulus. The annular holder receives in the rectangular groove an inner surface portion of the outer ring, and is tightly joined at the plastically deformable region to the inner surface portion of the outer ring. Also, a simplified method for making such a line guide device is provided.
Claims2
A line guide device for fishing rods comprising a unitary annular line guide ring holder, an outer ring, and a line guide ring, said annular holder comprising a metallic annulus having an annular rectangular groove on the outer periphery thereof, said outer ring being defined by a metallic annulus, said annular holder receiving an inner surface portion of said outer ring in said rectangular groove and being tightly joined to said inner surface portion of said outer ring by plastic deformation of said annular holder prior to insertion of said line guide ring into said annular holder.
A method for manufacturing a line guide device for fishing rods comprising the steps of:
- forming a unitary outer ring of a metallic material such that the inner surface is defined by an annulus,
- forming an annular line guide ring holder of a metal with an outer diameter equal at most to the inner diameter of said outer ring and in the form of an annulus having an annular rectangular groove on the outer periphery thereof, said groove being capable of receiving an inner surface portion of said outer ring,
- bringing said annular holder in touch with the rest of said inner surface of said outer ring,
- increasing the diameter of said annular holder by radial and outward plastic deformation thereby joining said peripheral groove to said inner surface portion of said outer ring, and
- thereafter mounting a line guide ring within said annular holder.
