Definitions

  • the present invention relates to a swim and dive fin.
  • Conventional swim fins are packaged at the time of purchase, in enclosures of various shapes and sizes.
  • Those packages can be constituted by a containment body that encloses the two fins, as occurs for example in the case of bags, or more simply by a wrapping or band made of heat-shrink plastics, which keeps them together.
  • the packaging is meant exclusively to put the fins on display for purchase.
  • the packages used to market swim fins in fact generally have a short life and cannot be reused except in the case of plastic bags or similar containers, which in any case are not very strong and wear rapidly in addition to being awkward to use.
  • the aim of the present invention is to provide a swim and dive fin that overcomes the cited drawbacks of the prior art.
  • An object of the invention is to provide a fin that allows to store and carry a pair of fins easily and comfortably.
  • Another object of the invention is to provide a fin that is constructively simple and reliable in use and can be manufactured at competitive costs.
  • Another object is to provide a fin that is substantially similar to a conventional fin in terms of space occupation and in use. Another object is to provide a fin that can be manufactured with materials and machines also suitable for producing conventional fins.

  • Figure 18 is a view, similar to Figure 17, of the coupling position.
  • a swim and dive fin according to the invention is constituted, in a per se known manner, by an elongated shoe that has a foot pocket 2, 102, 202, 302 that is suitable to contain the foot of the user and a blade portion 3, 103, 203, 303 that constitutes the propelling portion of the fin.
  • the fin 1 , 101 , 201, 301 includes one or more tabs 4,
  • 204, 304 are suitable to engage matching receptacles 5, 105, 205, 305 of a matching fin that is coupled to the fin 1, 101 , 201 , 301 , while the receptacles 5, 105, 205, 305 are suitable to accommodate the tabs 4, 104, 204, 304 of the matching fin.
  • the fin 1 includes a single tab 4, which is formed on the front edge 6 of the blade portion 3 and constitutes a sort of extension thereof.
  • the fin 1 has a single slot 5 that is obtained by means of a case member 7 provided in the structure below the foot pocket 2.
  • the receptacle 5 is protected against the penetration of sand or other foreign matter when the fins are used by a protective membrane 8, which can be obtained monolithicaliy with the case member and can be deformed elastically in order to allow the insertion of the tab 4, as clearly shown in Figures 4 and 5.
  • FIGS 6 to 18 illustrate further embodiments of the fin according to the invention among the many that are possible.
  • the fin 101 includes a single tab 104, which is formed on the lower surface 106 of the fin 101 at the end of the blade portion 103.
  • the fin 101 further has a single slot 105, which is formed on a protruding flap 106 that is obtained from the foot pocket and substantially constitutes an extension of the lower surface 106 beyond the foot pocket 102.
  • the tab 104 is substantially fin-shaped and is elongated toward the outside of the blade 103 so that it can be inserted in the corresponding seat 105 of the matching fin, engaging therewith.
  • the respective lower surfaces 106 are arranged mutually adjacent so that the foot pocket 102 of one fin is located at the blade portion 103 of the other, so that the tab 104 of one fin lies at the slot 105 of the other fin 101.
  • the elastic deformability of the fins allows to slide the tab 104 inside the slot 105, so as to reach a stable locking position in which the two fins 101 are mutually engaged, forming an assembly whose length is equal to the length of the individual fin 101 , as shown in Figures 8 and 9.
  • the elastic deformability of the fins 101 allows the sliding of the tab 104 for the mutual disengagement of the fins.
  • the fin 201 includes two tabs
  • the fin has two corresponding receptacles or slots 205, which are also symmetrical with respect to the longitudinal axis of the fin and are arranged at the blade portion 203 but are adjacent to the foot pocket 202.
  • Each tab 204 is substantially fin-shaped and is elongated toward the end of the blade 203 so that it can be inserted in the corresponding receptacle 205 of the matching fin, engaging with it.
  • the fins 201 When the fins 201 are not used, they can be coupled by arranging the respective lower surfaces 206 mutually adjacent, so that the blade portion 203 of one fin lies at the foot pocket 202 of the other fin and so that each tab 204 is arranged proximate to the corresponding slot 205.
  • the tabs 204 are made to slide within the respective slots 205, for both fins 201, until a stable locking position is reached in which the fins 201 mutually engage.
  • the two fins 201 are coupled with their respective lower surfaces in contact, so that as a whole they do not exceed the length of the individual fin 201. It is possible to disengage the tabs 204 from the respective slots 205 by forcing the mutual spacing of the fins 201 until they uncouple completely.
  • the fin 301 includes a single tab 304 that is formed on the front edge 306 of the blade portion 203, constituting a sort of extension thereof.
  • the fin 301 has an open slot 305, which is obtained by means of a bridge 307 that is provided in the fin below the foot pocket 302.
  • the tab 304 includes a raised portion 308 which blocks the tab inside the slot 305 by interference with the bridge 307, as shown in Figure 18.
  • the elastic deformability of the fins allows to make the tab 304 slide within the slot
  • the elastic deformability of the fins 301 and particularly of the bridge 307 and of the tab 304 allows the sliding of the tab 304 for the mutual disengagement of the fins.
  • the invention achieves the intended aim and objects, since it has provided a swim and dive fin that allows to couple the fins rapidly and easily and without using external components.
  • the fin according to the invention allows particularly handy carrying and allows to stow the fins after use with minimal space occupation.
  • the fin has the great advantage of eliminating the need for packaging for transport and for display and sale, thus avoiding the use of material that will ultimately be discarded into the environment.
  • the fin according to the invention has the additional advantage that the tabs and slots, sized and shaped appropriately, not only do not hinder the normal operation of the fin but also can increase the propulsion efficiency of the fins.
  • the materials used, as well as the dimensions, may of course be any according to requirements and to the state of the art.
