Mask for a water activity

Abstract

A mask for a water activity is provided. The mask includes two lenses, a waterproof skirt and a fastening device. The waterproof skirt is integrally formed with two lens frames, a nose covering portion and a rear edge. The two lens frames are independent of each other and each of them has an inner portion, in which the two lenses are embedded in the two lens frames in a watertight manner, respectively. The nose covering portion protrudes forward between the two lens frames. The rear edge is configured to closely fit a face of a user. When the user wears the mask through the fastening device, the two inner portions of the two lens frames are configured to be adjacent to two orbital bones of the user, respectively.

What is claimed is: 
     
         1 . A mask for a water activity, comprising:

 a nose covering portion connecting the two lens frames and protruding forward between the two lens frames; 
 a rear edge being configured to fit a face of a user; and 
   a fastening device, disposed between two outer ends of the waterproof skirt;   wherein when the user wears the mask through the fastening device, the two inner portions of the two lens frames are configured to be adjacent to two orbital bones of the user, respectively.   
     
     
         2 . The mask of  claim 1 , further comprising two connecting portions, one of which is formed between the nose covering portion and one of the two lens frames, and the other of which is formed between the nose covering portion and the other of the two lens frames, whereby when the user wears the mask, the nose covering portion is configured to cover the entire nose of the user and the two connecting portions are configured to substantially cover cheekbones of the face of the user. 
     
     
         3 . The mask of  claim 2 , wherein the rear edge has a notch portion formed on an upper portion of the nose covering portion, wherein the notch portion slightly bulges forward to form a bump, whereby when the user wears the mask, the bump is configured to fit along a contour defined by a glabella and a nasal bone of the face of the user. 
     
     
         4 . The mask of  claim 1 , wherein at least one of an upper portion, a lower portion and the inner portion of each of the two lens frames is provided with a reinforced structure, whereby when the user wears the mask, the reinforced structure is configured to abut against at least one portion of the two orbital bones of the user. 
     
     
         5 . The mask of  claim 4 , wherein the reinforced structure is provided on at least one of the upper portion, and the lower portion of each of the two lens frames, and the reinforced structure is a recess integrally formed with the waterproof skirt. 
     
     
         6 . The mask of  claim 1 , further comprising a breathing tube being in fluid communication with an inner cavity defined by the nose covering portion. 
     
     
         7 . The mask of  claim 6 , further comprising a three-way connector having a mouthpiece portion, a drain valve portion and a nose connecting portion, which are in fluid communication with one another, wherein the nose connecting portion is in fluid communication with the inner cavity of the nose covering portion. 
     
     
         8 . The mask of  claim 4 , wherein the reinforced structure is a reinforced rib, which is attached to an inner side of the waterproof skirt or is integrally formed with the waterproof skirt. 
     
     
         9 . The mask of  claim 8 , wherein the reinforced rib and the waterproof skirt are made of different materials and have a Shore A hardness ranging between 20 and 60. 
     
     
         10 . The mask of  claim 6 , wherein the reinforced rib is formed by thickening the waterproof skirt, and has a Shore A hardness ranging between 40 and 80. 
     
     
         11 . The mask of  claim 8 , further comprising a breathing tube being in fluid communication with an inner cavity defined by the nose covering portion. 
     
     
         12 . The mask of  claim 11 , further comprising a three-way connector having a mouthpiece portion, a drain valve portion and a nose connecting portion, which are in fluid communication with one another, wherein the nose connecting portion is in fluid communication with the inner cavity of the nose covering portion. 
     
     
         13 . The mask of  claim 4 , wherein the reinforced structure is a gasket provided on the inner portion of each of the two lens frames. 
     
     
         14 . The mask of  claim 13 , further comprising a breathing tube being in fluid communication with an inner cavity defined by the nose covering portion. 
     
     
         15 . The mask of  claim 14 , further comprising a three-way connector having a mouthpiece portion, a drain valve portion and a nose connecting portion, which are in fluid communication with one another, wherein the nose connecting portion is in fluid communication with the inner cavity of the nose covering portion. 
     
     
         16 . The mask of  claim 1 , wherein each of the two lens frames has an annular groove formed on an inner edge thereof for each of the two lenses to be respectively embedded therewithin in a watertight manner. 
     
     
         17 . The mask of  claim 1 , wherein the two lens frames are integrally injection-molded with the two lenses. 
     
     
         18 . The mask of  claim 1 , wherein the fastening device is an elastic head strap.
