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:

Claims (7)

1. Palme de natation dans laquelle la partie voilure (1) et la partie chausson (2) sont réalisées séparément, et sont reliées ensemble de façon amovible par des moyens d'accouplement qui comprennent:
a)   une languette aplatie (3) qui s'étend vers l'arrière à partir de l'extrémité de la partie voilure (1) contiguë à la partie chausson (2), et qui, lorsque les deux parties de palme (1, 2) sont reliées ensemble, s'adapte dans un évidement (4) de forme correspondante prévu dans la partie chausson (2);
b)   un élément transversal de pontage (6) faisant partie intégrante de la partie voilure (1) et recouvrant la partie avant de la partie chausson (2), lorsque les deux parties (1, 2) sont reliées ensemble;
c)   un dispositif de verrouillage pour bloquer ensemble les deux parties de palme accouplées,
caractérisée par la combinaison des caractéristiques suivantes:
d)   l'évidement (4) qui doit recevoir la languette (3) est formé dans l'épaisseur de la semelle (5) de la partie chausson (2);
e)   le dispositif de verrouillage pour verrouiller ensemble les deux parties de palme (1, 2) comprend un petit cliquet flexible (11) formé dans la languette (3) de la partie voilure (1), et agencé pour venir en prise élastiquement, au moment où lesdites parties voilure et chausson (1, 2) sont reliées ensemble, avec un loquet formé sur la partie chausson (2);
f)   un dispositif de sécurité (15, 215) empêchant le cliquet (11) du dispositif de verrouillage d'être manoeuvré accidentellement.

2. Palme de natation selon la revendication 1, caractérisée en ce que le dispositif de verrouillage comprend des moyens pour dégager le cliquet (11) du loquet formé sur la partie chausson (2) après que le dispositif de sécurité (15, 215) a été rendu inopérant.
3. Palme de natation selon les revendications 1 et 2, caractérisée en ce que le moyen pour dégager le cliquet (11) comprend une languette (13) qui est formée par une découpe dans la partie voilure (1) dans la zone où le cliquet (11) rejoint la languette (3), en sorte qu'en appuyant manuellement sur la languette (3) vers le bas, le cliquet (11) se déplace vers le haut, l'étroite bande de matériau (14) entre la languette et le cliquet servant d'articulation.
4. Palme de natation selon les revendications 1 à 3, caractérisée en ce que le dispositif de sécurité comporte un petit bouton (15), monté rotatif sur la languette (13), et qui est muni d'un ergot radial (215) permettant d'actionner la languette (13) uniquement lorsque cet ergot (215) est aligné avec une encoche (101) formée dans le bord de la fente délimitant ladite languette, et empêche l'actionnement de la languette (13) lorsque cet ergot se trouve dans une autre position quelconque, du fait qu'il heurte le bord de ladite fente.
5. Palme de natation selon l'une quelconque des revendications précédentes, caractérisée en ce que sur les deux parties de palme reliées ensemble, l'élément transversal de pontage (6) de la partie voilure (1) est sollicité pour venir en contact avec un élément d'engagement (9) formé dans la partie chausson (2) et constitué par une rainure transversale.
6. Palme de natation selon l'une quelconque des revendications précédentes, caractérisée en ce que l'élément transversal de pontage (6) est supporté des deux côtés par deux nervures (7) constituant des prolongements de deux nervures intermédiaires (8) de la partie voilure (1) et qui, lorsque les deux parties de palme (1, 2) sont reliées ensemble, sont amenées en engagement avec deux éléments d'engagement (10) constitués par des bossages latéraux plats.
