Abstract

Abstract A metallic main frame including an eye ring and a seat tube joined in one body to the eye ring is coupled with an elastic protective sleeve to be inserted over fishing rods. The elastic nature of the protective sleeve tends to do less damage to the surface of the fishing rods and the absence of a brazed joint assures enhanced strength of the assembly construction.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 229 words
A line guide assembly for a fishing rod comprising, in combination, a metallic main frame of an integral single body construction, said main frame having a seat tube for receiving the fishing rod, a pair of substantially parallel arms upstanding from one edge of said tube, and an eye ring for passing a fishing line therethrough, supported by said arms with its axis parallel to the axis of said seat tube; and an elastic protective sleeve forcedly inserted into said seat tube, the axial length of said sleeve being larger than that of said seat tube; said seat tube having a plurality of axially aligned grooves in the inner periphery thereof and said sleeve having a corresponding number and shape of axially aligned projections on the outer periphery thereof, said grooves and projections thereby cooperating to prevent relative axial movement between said sleeve and said tube; said sleeve having a flange around the outer periphery and at one end thereof, said flange abutting one end of said tube; said tube having a circular lip at the inner periphery of the other end thereof to engage the outer surface of said elastic sleeve; said flange and said lip thereby preventing separation of said tube and said sleeve; said sleeve having a plurality of axially aligned indentations on the inner periphery thereof to provide a secure grip on the fishing rod.
Claim 2
Dependent Claim 229 words
A line guide assembly for a fishing rod comprising, in combination, a metallic main frame of an integral single body construction, said main frame having a seat tube for receiving the fishing rod, a pair of substantially parallel arms upstanding from one edge of said tube, and an eye ring for passing a fishing line therethrough, supported by said arms with its axis parallel to the axis of said seat tube; and an elastic protective sleeve forcedly inserted into said seat tube, the axial length of said sleeve being larger than that of said seat tube; said seat tube having a plurality of axially aligned grooves in the inner periphery thereof and said sleeve having a corresponding number and shape of axially aligned projections on the outer periphery thereof, said grooves and projections thereby cooperating to prevent relative axial movement between said sleeve and said tube; said sleeve having a flange around the outer periphery and at one end thereof, said flange abutting one end of said tube; said tube having a circular lip at the inner periphery of the other end thereof to engage the outer surface of said elastic sleeve; said flange and said lip thereby preventing separation of said tube and said sleeve; said sleeve having a plurality of axially aligned indentations on the inner periphery thereof to provide a secure grip on the fishing rod.
Claim 3
Dependent Claim 25 words
A line guide assembly as claimed in claim 1 in which the inner periphery of said eye ring of said main frame is convexly rounded.
Claim 4
Dependent Claim 39 words
A line guide assembly as claimed in claim 1 further comprising an elastic intermediate ring forcedly inserted into said eye ring of said main frame and a guide ring of high abrasion resistance forcedly inserted into said intermediate ring.
Claim 5
Dependent Claim 19 words
A line guide assembly as claimed in claim 3 in which said guide ring is made of a ceramic.
Claim 6
Dependent Claim 20 words
A line guide assembly as claimed in claim 1 in which said protective sleeve is made of a synthetic resin.
