Abstract:
1. An air valve connecting device comprising: a housing including a chamber formed therein, and including a first end portion, and including a second end portion, a mouth attached to said first end portion of said housing and including a compartment formed in said mouth for receiving and engaging with a U.S. type valve, and including a bore formed in said mouth and having an inner diameter smaller than that of said compartment of said mouth for receiving and engaging with a French type valve, a barrel engaged into said chamber of said housing and engaged onto said mouth, and including a bore formed therein for receiving the French type valve, said barrel including a frustum-shaped space formed therein, an actuator slidably engaged in said second end portion of said housing, and including a shank extended therefrom for engaging with said barrel, and including a chamber formed in said shank of said actuator for selectively receiving and engaging with the French type valve, and including at least one slit formed in said shank for forming at least one spring blade and for allowing said at least one spring blade of said shank of said actuator to be selectively forced to engage with the French type valve and to retain the French type valve to said actuator, said actuator including a pawl extended from said at least one spring blade for selectively engaging with the French type valve, and said actuator including a frustum-shaped segment formed in said at least one spring blade of said shank, a first spring biasing member for biasing said actuator away from said barrel, a tube slidably engaged in said chamber of said shank of said actuator for selectively engaging with the French type valve, and said tube being extendible into said compartment of said mouth for selectively engaging with the U.S. type valve, said tube including a peripheral recess formed therein, said pawl of said actuator being selectively engageable with said peripheral recess of said tube, said frustum-shaped segment of said actuator being selectively engageable with said frustum-shaped space of said barrel for selectively forcing said pawl of said at least one spring blade to selectively engage with either said peripheral recess of said tube or the French type valve, a second spring biasing member for biasing said tube to selectively engage with either the French type valve or the U.S. type valve, and a handle pivotally attached to the housing and including a cam member provided on one end thereof for engaging with said actuator and for forcing said at least one spring blade of said actuator to selectively engage with either the French type valve or said tube, and for forcing said mouth to selectively engage with either the French type valve or the U.S. type valve.
