Detachably coupled swim fins

Abstract

A pair of swim fins may be detachably coupled together to form a monofin. An elongated projection running along and extending from the inner edge of a first fin releasably mates with a C-shaped linear slot formed in a projection at the inner edge of the second fin, the slot slidably receiving the projection of the first fin via an opening at one end of the slot. A stopper means located at the other end of the slot prevents further movement of the projection of the first fin along the slot once the fins are properly aligned, and the c-shaped slot prevents relative movement of the find in a direction perpendicular to the length of the slot.

1 . A monofin comprising:
 a first swim fin;   a second swim fin, each of said fins having an integral pocket for receipt of a portion of a user's foot;   an elongated projection running along and extending from the inner edge of the first fin   an elongated projection running along and extending from the inner edge of the second fin, and having a linear slot to slidably receive the projection of the first fin through an opening at one end of the slot; and   a stopper comprising a wall located across the other end of said slot of said second fin to stop further movement of the projection of the first fin along the slot of the second fin once the fins are properly aligned.   
     
     
         2 . The monofin of  claim 2 , wherein the elongated projection of the first fin and the slot in the elongated projection of the second fin are shaped to prevent movement between the fins in a direction perpendicular to the axis of the slot. 
     
     
         3 . The monofin of  claim 2 , wherein the elongated projection of the first fin generally has the shape of a T in cross-section, and the slot has the general shape of a C in cross-section. 
     
     
         4 . The monofin of  claim 2 , wherein each swim fin has a first end and a second end, the pocket for receipt of a portion of a user's foot being located at the first end, and the opening in the slot of the second fin being located closer to the first end of the fin than the second end.
