Suit having water-inflow double-blocking function

Abstract

Disclosed is a suit having a water-inflow double-blocking function. The suit includes a lower body portion, an upper body portion coupled to a top of the lower body portion and integral with the lower body portion, wherein the upper body portion has an opening defined in a top center of the upper body portion, and a neck cover coupled removably to the upper body portion, the neck cover including: a neck portion surrounding a neck, and an extension extending outwardly from a bottom of the neck portion to surround the neck, wherein the extension is inserted into the opening of the upper body portion and is coupled to an inner surface of the upper body portion, wherein the neck cover prevents water from flowing into the opening of the upper body portion.

What is claimed is: 
     
         1 . A suit having a water-inflow double-blocking function, the suit comprising:
 a lower body portion;   an upper body portion coupled to a top of the lower body portion and integral with the lower body portion, wherein the upper body portion has an opening defined in a top center of the upper body portion; and   a neck cover coupled removably to the upper body portion, the neck cover including:
 a neck portion surrounding a neck; and 
 an extension extending outwardly from a bottom of the neck portion to surround the neck, wherein the extension is inserted into the opening of the upper body portion and is coupled to an inner surface of the upper body portion, wherein the neck cover prevents water from flowing into the opening of the upper body portion, 
   wherein the upper body portion includes an over-head cover having one side part fixed to a rear portion of the upper body portion, and having the other side part coupled to a front portion of the upper body portion and extending across a central top of the upper body portion, wherein the over-head cover has a head receiving hole defined therein through which a head passes, wherein the over-head cover covers the opening of the upper body portion receiving the extension of the neck cover and thus seal the neck, thereby blocking water inflow to the opening of the upper body portion in a double manner,   wherein the over-head cover further includes water-proof rubbers and water inflow prevention films for blocking water inflow while the over-head cover covers the opening of the upper body portion and thus seals the neck,   wherein each of the water-proof rubbers is embedded into each of both lateral ends of the over-head cover to first block inflow of water while the over-head cover covers the opening of the upper body portion and thus seals the neck, and   wherein the water inflow prevention films are disposed inwardly of the water-proof rubbers, and second blocks inflow of water not blocked by the water-proof rubbers.   
     
     
         2 . The suit of  claim 1 , wherein the water inflow prevention films are arranged on each of an inner surface of the over-head cover and an outer surface of the upper body portion and are spaced apart from each other at a predetermined spacing. 
     
     
         3 . The suit of  claim 2 , wherein the water inflow prevention films formed on the inner surface of the over-head cover and the water inflow prevention films formed on the outer surface of the upper body portion are arranged in a zigzag form, such that the water inflow prevention film formed on the outer surface of the upper body portion blocks a gap between the adjacent water inflow prevention films formed on the inner surface of the over-head cover. 
     
     
         4 . The suit of  claim 1 , wherein each of the water-proof rubbers is made of an elastic rubber and pressurizes each of the both lateral ends of the over-head cover to allow the both lateral ends of the over-head cover to be in close contact with the upper body portion. 
     
     
         5 . The suit of  claim 1 , wherein the upper body portion further includes a fixing cover fixed to the front portion of the upper body portion,
 wherein the fixing cover includes a zipper to couple and fix the other side part of the over-head cover to the front portion of the upper body portion.   
     
     
         6 . The suit of  claim 1 , wherein one of female and male snap buttons is formed on each of front and rear portions of the extension of the neck cover and the other of female and male snap buttons is formed on each of the front and rear portions of the upper body portion so that the neck cover is detachably coupled to the upper body portion using the female and male snap buttons. 
     
     
         7 . The suit of  claim 1 , wherein a water-proof rubber is disposed on an inner surface of the neck cover to allow the neck cover to closely adhere to a skin of the neck, thereby preventing water from flowing through a gap between the neck cover and the neck into the opening of the upper body portion.
