Abstract:
A fishhook comprising:a one-piece monolithic body which includes a) first and second legs, each having a distal end, a distal portion, a proximal portion, and a proximal end; b) a barb on said distal end of each of said first and second legs; c) a torsion spring connecting said proximal end of said first leg to said proximal end of said second leg; d) said torsion spring biasing the proximal end of said first leg toward the proximal end of said second leg in an armed configuration of said one-piece monolithic body such that the axes of the proximal portions of said first and second leas cross each other at a first location, and wherein the axes of the proximal portions of said first and second legs cross each other at a second location which is closer to the torsion spring than the first location in a triggered configuration of said one-piece monolithic body; e) a notch portion in said first leg which is oriented at an oblique angle with respect to the distal and proximal portions of the first leg; f) a notch portion in said second leg which is oriented at an oblique angle with respect to the distal and proximal portions of the second leg; g) said notch portion in said first leg abutting said notch portion in said second leg along a plane which is transverse to a plane in which the torsion spring extends when said one-piece monolithic body is in an armed configuration and being spaced apart from said notch portion in said second leg when said one-piece monolithic body is in a triggered configuration; and h) said distal ends of said first and second legs curving away from each other and moving in a common plane when said one-piece monolithic body moves from the armed configuration to the trigged configuration.
