Definitions

  • the present invention has as its object a flipper-sandal, that is to say footwear that combines the functions of a shoe and those of a swimming aid.
  • flippers To improve performance when swimming the use of flippers is well known. These flippers have a larger surface area than the surface area of the foot, and allow the swimmer to move a greater volume of water when swimming. However, they are not suited for use when walking normally.
  • the present invention solves this problem, by providing a flipper-sandal that comprises a sandal base, an inner sole positioned under the sandal base, and an outer sole positioned under the inner sole, said inner and outer soles being connected to each other and to the sandal base and being movable horizontally from a sandal position in which they correspond to the position of the sandal base, and a flipper position in which they are moved forwards and outwards to opposite sides with respect to the position of the sandal base, said outer sole comprising a movement element to move the inner and outer soles from the sandal position to the flipper position.
  • Figure 1 shows a longitudinal section view of the sandal base 1 of the flipper-sandal according to the invention.
  • First and second locking and sliding elements 5, 6 are present, for example pins, the top end areas of which are arranged inside the base 1.
  • a hollow region 32 to house a connection element, which will be described below, to connect the inner and outer soles to the base 1.
  • Figure 1 is shown in cross-section along line A-A of the base 1 illustrated in figure 2.
  • Said figure 2 shows a plan view from above of the base 1, in which the blocking and sliding elements 5, 6 are positioned, indicated by dashed lines in the figure.
  • This base also has recesses 21, 22 arranged at the front, suitable to house respective projections on the outer sole, which will be described in the following.
  • hollow regions 32 to house an element for connection of the inner and outer soles to the base 1. These hollow regions 32 are formed within an area 19 that forms an integral part of the base 1.
  • Figure 3 shows a plan view from above of the inner sole 2 positioned under the base 1. It comprises a first central slot 9, in which the second blocking and sliding element 6 slides, arranged centrally and extending in a longitudinal direction with respect to the position of the foot; there is also a first front slot 10, in which the first blocking and sliding element 5 slides, arranged at the front and extending obliquely with respect to the direction of the foot; there is also a first rear slot 11, in which an additional blocking element on the outer sole slides, which will be described in the following, said slot being positioned at the back and consisting of a first longitudinal section 12 and a substantially transversal section 13.
  • the inner sole 2 also has recesses 23, 24 arranged at the front, capable of housing respective projections on the outer sole, which will be described in the following.
  • Metal sheets are inserted within the inner sole 2, around the first slots 9, 10 and 11, in order to encourage sliding of the blocking elements within said first slots 9, 10 and 11. These metal sheets are shown in a partial and schematic manner in the figure and are indicated by a dotted line and the numbers 27, 28 and 29, respectively.
  • Figure 4 shows a section view of the inner sole 2 along the line B-B of figure 3, in which it is possible to see in greater clarity the arrangement of the metal sheets 27, 28 and 29.
  • Figure 5 shows a plan view from above of the inner sole 3.
  • a second central slot 14 is present in which to slide the second blocking and sliding element 6, arranged centrally and extending in a longitudinal direction with respect to the direction of the foot.
  • the second central slot 14 in the outer sole 3 is longer than the first central slot 9 in the inner sole 2 by a section that approximately corresponds to the length of the first longitudinal section 12 of the first rear slot 11 in the inner sole 2.
  • Said second longitudinal section 17 is as long as the first longitudinal section 12 in the first rear slot 11.
  • a third blocking and sliding element 7 protruding therefrom, the lower end area of which is within the outer sole.
  • projections 25, 26 arranged at the front, capable of inserting into the respective recesses 21, 22 in the base 1 and 23, 24 in the inner sole 2.
  • a movement element 4 is arranged on the rear part of the outer sole 3; this element, which will be described in greater detail in the following figures, serves to move the inner and outer soles 2, 3 with respect to the base 1 when passing from the sandal position to the flipper position.
  • Said element 4 forms an integral part of the outer sole 3 and can either be made in one piece therewith, or be made separately and subsequently joined together. It is illustrated in the figure, for example, as being of a different material from the material of which the outer sole 3 is made.
  • Metal sheets are inserted into the outer sole 3, around the slots 14 and 15, in order to encourage sliding of the blocking elements within the second slots 14, 15. These metal sheets are illustrated schematically in the figure and are indicated by a dotted line and the numbers 30 and 31, respectively.
  • Figure 6 shows a section view of the outer sole 3 along line C-C of figure 5, in which it is possible to see more clearly the arrangement of the metal sheets 30, 31.
  • areas 33, 34 for housing of the bottom end of the respective blocking and sliding elements 5, 6.
  • the projection 25 is visible at the front end, and is capable, along with the projection 26, not visible in this section, of fittedly engaging with the respective recesses 21, 22 and 23, 24 in the base 1 and in the inner sole 2, respectively, to keep the sandal in position.
  • the movement element 4 capable of moving the inner and outer soles 2, 3 with respect to the base 1 when passing from the sandal position to the flipper position.
  • the third blocking and sliding element 7 is inserted into said movement element 4.
  • the movement element 4 further comprises a connection element 8, for connection of the outer sole 3 to the base 1 by means of insertion into the hollow regions 32.
  • Figure 7 shows a longitudinal section view of the base 1 and the inner and outer soles 2 and 3 as a whole, together with the blocking and sliding elements 5, 6, 7.
  • the inner sole 2 slidingly engages with the blocking and sliding elements 5, 6 and 7 by means of the respective first slots 10, 9 and 11, and through the respective metal sheets 28, 27 and 29 aiding sliding of said blocking and sliding elements.
  • the outer sole 3 is arranged below the inner sole 2, and slidingly engages with the blocking and sliding elements 5, 6 by means of the respective slots 15, 14 and through the respective metal sheets 31, 30 aiding sliding.
  • the base 1 and the inner and outer soles 2, 3 are kept in sliding contact with each other by locking of the bottom head of each blocking and sliding element 5, 6 inside the respective areas 33, 34 formed in the outer sole 3.
  • the connection element 8 is visible, belonging to the movement element 4, also illustrated in the figure.
  • Figure 8 shows a rear view of the element 4 for movement of the inner and outer soles 2, 3 with respect to the base 1, in which the connection element 8 is more clearly seen, comprising end areas 35, 36 for connection with the hollow regions 32 of the base 1. There is also a handle area 37.
  • Figure 9A shows the flipper-sandal in the sandal position.
  • the element 4 of the outer sole 3, not shown in the figure is in the position illustrated in the preceding figure 7, with the connection element 8 inserted in the hollow regions 32 of the base 1 between the end areas 35 and 36.
  • the central slots 9, 14 are superimposed in such a way as to coincide throughout the entire length of the first central slot 9 and so that the second central slot 14 continues to extend beyond the rear end portion of the first central slot 9; the front slots 10, 15 on the contrary are superimposed in such a way as to coincide only at their front end portions.
  • the first blocking and sliding element 5 passes through the front end portions of the front slots 10, 15, in particular through the front end portion of the second longitudinal section 17 of the second front slot 15; the second blocking and sliding element 6 passes through the front end portions of the central slots 9, 14 and the third blocking and sliding element 7 passes through the rear end portion of the first longitudinal section 12 of the first rear slot 11.
  • the movement element 4 illustrated in figure 8 is gripped in the handle area 37, in such a way as to extract the connection element 8 with its end areas 35, 36 from the hollow regions 32.
  • the present invention is given above in an example embodiment, and is not intended to be limited thereto.
