Shoes for diving flippers and moulding device suitable for producing them

Abstract

The object of the present invention consists of shoes for diving flippers and the molding device suitable for producing them. More specifically, the object of the present invention consists of shoes of different sizes that can be obtained from a molding device equipped with a minimum number of interchangeable elements.

1 . Shoe for diving flipper that can be made in different sizes, characterized in that the outer surfaces of the shoes of different sizes are all the same and the difference between the different sizes is limited to the length of the shoe and the shape of the inner surface of the shoe.  
   
   
       2 . Shoe for diving flipper, according to  claim 1 , characterized in that, alternatively and/or in combination, the smaller inner size of smaller sized shoes are obtained through an increase in its thicknesses and/or through ribs projecting from the inner surface of the shoe.  
   
   
       3 . Molding device for shoes for diving flippers, of the type that foresees at least two female and at least one male shells, suitable for defining the outer and inner surfaces, respectively, of different sized shoes for diving flippers, characterized in that it foresees a single series of female shells, for making the outer surface of different sized shoes, and different sized male members, preferably of decreasing size, for defining the inner surface of the shoe.  
   
   
       4 . Molding device for shoes for diving flippers, according to  claim 3 , characterized in that the male members intended for forming shoes of progressively smaller sizes are equipped with ribs of a size that increases as the size of the shoe to be molded decreases.  
   
   
       5 . (canceled)
