Inflating device

Abstract

The present invention relates to an inflating device that can be used for inflating an inflatable boat having two sides and a bottom, each having an independent air chamber, the device including a sealed body with an enclosure having at least three communication openings, each of the openings being connected to another opening by a passage for the circulation of a flow of air, and in particular a first opening intended to be connected to a first air supply means intended to supply air to the air chamber of the first side fender of the inflatable boat, a second opening intended to be connected to a second air supply means intended to supply air to the air chamber of the second side fender of the inflatable boat, a third opening intended to be connected to an air pump, and means for shutting off the passage between the first opening and the second opening, the means being disposed in the enclosure and being able to move between a first position, called the open position, in which the passage between the first opening and the second opening is open, and a second position, called the closed position, in which the passage between the first opening and the second opening is closed.

1 . An inflating device capable of being used for inflating an inflatable boat including two side tubes and a bottom respectively including an independent air chamber, said device comprising:
 a sealing body comprising an enclosure having at least three communication openings, each of the openings being connected to another opening with a passage allowing for airflow circulation, said openings comprising:
 a first opening to be connected to a first air routing means for supplying air to the air chamber of the first side tube of the inflatable boat, 
 a second opening to be connected to a second air routing means for supplying air to the air chamber of the second side tube of the inflatable boat, 
 a third opening to be connected to an inflating pump, and 
   means for blocking the passage between the first opening and the second opening, arranged inside the enclosure and movable between a first opening position, wherein the passage between the first opening and the second opening is open, to a second closing position, wherein the passage between the first opening and the second opening is closed,   means for positioning the blocking means in an intermediate position located between the opening position and the closing position,   the third opening being made on the positioning means.   
     
     
         2 . The inflating device according to  claim 1 , wherein the positioning means include the blocking means. 
     
     
         3 . The inflating device according to  claim 1 , wherein the positioning means comprise a tappet member and a handling member embodying a motion conversion device of the screw-and-nut type converting a relative rotary motion of the handling member into a relative translatory motion of the tappet member so as to bring the blocking means into the closing position thereof. 
     
     
         4 . The inflating device according to  claim 1 , wherein the positioning means include a non-return device. 
     
     
         5 . The inflating device according to  claim 1 , wherein the enclosure includes two removable parts. 
     
     
         6 . The inflating device according to  claim 1 , including locating means for the closing position and/or for the opening position, in particular for a position for inflating the inflatable boat. 
     
     
         7 . The inflating device according to  claim 1 , wherein the enclosure has a fourth opening to be connected to a third air routing means for supplying air to the air chamber of the bottom of the inflatable boat, each of the openings being connected to another opening by a passage allowing for airflow circulation in the opening position. 
     
     
         8 . The inflating device according to  claim 7 , wherein the passages between the first opening or the second opening and the fourth opening are open in the opening position of the blocking means, and the passages between the first opening or the second opening and the fourth opening are closed in the closing position of the blocking means. 
     
     
         9 . The inflating device according to  claim 7 , wherein the section of the fourth opening is undersized with respect to the sections of the first opening and the second opening. 
     
     
         10 . The inflating device according to  claim 1 , wherein the blocking means can be removed from the enclosure. 
     
     
         11 . An inflatable boat comprising an inflating device as described in  claim 1 .
