Strap and retainer for a divers mask

A mask for a diver having a viewing port and a seal with a strap to hold the mask on a user's head comprising:

• a frame portion that is formed with a viewing port therethrough;
• means on said frame for receiving a transparent lens within said viewing port for providing viewing by a diver;
• a skirt surrounding said frame with a seal thereon for being received against a diver's face and sealing the interior of the mask;
• clip support means extending from the two respective sides of said mask having a space therebetween;
• a clip member pivotally mounted between said support means;
• tooth means on said clip member having a substantially upright surface on the face of the tooth and a sloping surface on the opposite face of the tooth;
• spring means for providing spring bias to said clip means for causing said tooth to move in the direction of its end;
• a strap having ribs thereon with a substantially upright face and a sloping face opposite therefrom;
• means for supporting a loop of said strap between said clip member support means so that as said tooth engages a substantially upright surface of said rib with a matching upright surface it can block movement thereof by the spring bias of the clip against said tooth while permitting movement of said strap by said sloping face of said strap sliding against said sloping surface of said tooth against said spring bias.

A swimming fin with a strap for use therewith comprising:

• a swimming fin having a pocket for receipt of a user's foot;
• spaced support wall means extending from each side of said wall on each side of said user's foot pocket;
• a spring clip supported between each of said spaced wall means wherein said spring clip has a pivotal support between said support wall means and comprises a lever with a spring member at one end and a tooth at the other end wherein said spring member engages said wall of said fin;
• a transverse member extending between said spaced support wall means around which a loop of a strap can be looped;
• transverse rib means on said strap having a substantially upright surface and a sloping surface on the other side of said rib;
• and wherein,
• said tooth has an upright surface and a sloping surface thereof wherein said upright surface causes said upright surface of said ribs to be checked thereby and said sloping surface allows the sloping surface of said ribs to pass thereunder when said clip member is depressed so as to disengage itself or when said strap is pulled with said sloping surfaces of said ribs and tooth moving in mutually passing relationship to each other against the force of said spring clip.

A mask for a diver in combination with a strap wherein said mask is formed with a frame member having an opening passing therethrough to provide a diver's viewing port with a transparent lens implaced within said frame member overlying said port and a skirt and seal portion extending from said frame portion for engagement with a user's face wherein said strap and retainer means comprise:

• a strap having a plurality of transverse ribs thereon wherein said ribs have a substantially upright surface and a sloping surface in opposite relationship to said upright surface so as to provide a substantially upright surface and a sloping surface for said ribs terminating in a crown;
• at least two support members extending from said frame comprising bracket walls from the side of the frame;
• a clip member for providing retention of said strap formed as a pivoting lever member pivotally journaled between said bracket wall members extending from said frame wherein at one end of said lever a tooth is provided having a substantially upright surface terminating in a crown and a slanting surface from said crown opposite from said upright surface;
• spring means extending from said lever member in distal relationship from said tooth member on said lever member for biasing said lever member;
• transverse strap support means extending between said bracket walls for providing a holding member around which a loop of said strap can be oriented for holding it therein so that as said loop is passed therearound, the upright surfaces of said strap ribs can engage the upright surface of said tooth and be held therein by spring bias of said spring means of said lever;
• and,
• wherein said lever means and said tooth means and said spring means are formed as a single plastic molded item.
