Inflatable sup board

Abstract

The present invention relates to an inflatable stand up paddle (SUP) board that has a separate air chamber formed therein in addition to a tube that forms a main body, thereby achieving more enhanced safety, and conforms to national safety regulations. The SUP board comprises: a main body that is formed in the shape of a long plate and has a plurality of shape maintaining lines, each having opposite ends coupled to upper and lower internal surfaces, and a first air injection port installed on the front side of the upper surface thereof; a side sheet air-tightly bonded to the main body along the outer periphery thereof to form an air tube along with the main body; and an inner tube that is provided on the outer periphery of the main body and has a second air injection port installed on the outer surface of the side sheet to allow air to be injected thereunto, wherein the outer surface of the inner tube is attached to the internal surface of the side sheet.

1 ] An inflatable SUP board comprising:
 a main body  10  comprising a plurality of shape maintaining lines  11  coupled to both ends between upper and lower inner surfaces of the main body  10 , the main body  10  formed to have a long plate shape, the main body  10  having a first air inlet  12  at a front upper surface;   a side sheet  20  attached along an outer circumference of the main body  10  to encapsulate the main body  10  to form an air tube with the main body  10  and the side sheet  20 ; and   an inner tube  30  disposed at the outer circumference of the main body  10 , the inner tube  30  having an outer surface attached at an inner surface of the side sheet  20 , the inner tube having a second air inlet  31  disposed at the outer surface of the side sheet  20  to inject air thereinto.   
     
     
         2 ] The inflatable SUP board according to  claim 1 , wherein the inner tube  30  has a ring shape along the outer circumference of the main body  10 . 
     
     
         3 ] The inflatable SUP board according to  claim 1 , wherein the inner tube  30  is formed of polyvinyl chloride (PVC) or polyurethane. 
     
     
         4 ] An inflatable SUP board comprising:
 a main body  10  comprising a plurality of shape maintaining lines  11  coupled to both ends between upper and lower inner surfaces of the main body  10 , the main body  10  formed to have a long plate shape, the main body  10  having a first air inlet  12  at a front upper surface;   a side sheet  20  attached along an outer circumference of the main body  10  to encapsulate the main body  10  to form an air tube with the main body  10  and the side sheet  20 ; and   an outer sheet  40  surrounding the side sheet  20 , the outer sheet  40  attached to the outer circumference of the main body  10  to form a hollow space at an outside of the side sheet  20 , the outer sheet  40  having a third air inlet  41 , which is exposed.   
     
     
         5 ] The inflatable SUP board according to  claim 4 , wherein the outer sheet  40  has a ring shape along the outer circumference of the side sheet  20 . 
     
     
         6 ] The inflatable SUP board according to  claim 4 , wherein the outer sheet  40  is formed of the same material as the side sheet  20 .
