Definitions

  • This invention relates to a swim fin according to the pre-characterizing part of Claim 1.
  • the blade portion is provided at the rear end thereof, i.e., the end facing the shoe portion, with two lateral tang portions, designed for being fitted into matchingly shaped recesses formed in enlargements at the sides of the shoe portion.
  • the said enlargements give the shoe portion a certain stiffness, which makes it difficult to put on and uncomfortable to walk.
  • the locking device for locking the two coupled fin portions together consists of projecting, parts provided on the top side and the bottom side of the shoe portion, behind which respective transverse members made integral with the blade portion, are engaged. With this locking device, the operations for connecting together and disconnecting the two fin portions become rather difficult.
  • the invention aims to overcome the said diadvantages by the provision of a swim fin of the type as disclosed in the pre-characterizing part of Claim 1, wherein the means for coupling and locking the two fin portions together ensure a perfect solidarization thereof by a quick and easily performable operation, without the softness characterizing the shoe portion being affected.
  • the numeral 1 indicates the blade portion and 2 indicates the shoe portion of a swim fin according to the invention, said blade and shoe portions being constructed as separate members and being disconnectably interconnected by suitable coupling means.
  • the blade 1 which may be made of any suitable flexible material, either metallic, such as aluminum, or plastics, comprises at the rear end thereof, facing the shoe portion 2, a flattened tang portion 3 of substantially triangular configuration and at a small angle to the body of said blade. Said tang portion 3, of unitary construction with the blade 1 proper, is fitted, upon coupling the two fin portions together, into a correspondingly shaped recess 4 formed in the sole 5 of the shoe portion 2 which usually is made of rubber-like soft plastics material.
  • said blade 1 comprises, just above said tang portion 3, a transverse bridge member 6 which is supported at both sides by two ridge-members 7 which extend on the top surface of the blade so as to constitute a pair of stiffening ribs therefor.
  • a transverse groove 9 and two lateral flat seatings 10 are formed in the toe of the shoe portion 2, which, upon connecting the two portions of the swim fin, will be engaged by said bridge member 6 and ridge-members 7 of the blade portion, respectively.
  • said ridge-members 7 comprise a small triangular lug 107, co-planar with said ridge-member and extending towards said shoe portion.
  • Each lug 107 is designed, upon assembling the swim fin, to fit into a mating recess 110 in the respective seating 10 of the shoe portion.
  • the swim fin according to the invention comprises a snap-detent locking device.
  • Said snap-detent device comprises a flexible detent 11 formed in the tang portion 3, particularly in the area thereof joining the body of the blade 1. Upon connecting said blade and shoe portions together, said detent 11 will engage by a snap action with a catch 12 formed on the toe of said shoe, so as to firmly connect the two fin portions together.
  • Said locking device additionally, comprises means to easily lift said detent 11 to separate the two fin portions.
  • Said means comprises a tongue 13 which is formed by cutting through the blade at the area where said detent 11 joins the tang portion 3, so that by manually depressing said tongue downwards said detent will be moved upwards, the narrow strip of material 14 between the former and the latter acting as a hinge (see Fig. 7).
  • Said locking device is provided also with safety means against any inadvertent actuation of the tongue 13.
  • Said means comprises a small knob 15 rotatably mounted on the tongue 13 through a spindle 115, and provided with a radial pin 215 which normally, by striking against the edge of the slot defining said tongue 13, prevents any actuation of the latter.
  • said actuation can be effected by purposely rotating said knob 15 so as to bring said pin 215 in register with a notch 101 formed in the edge of said slot.
  • a swim fin according to the invention has, when compared to the conventional swim fin of the same type, several advantages including:
