Hand pump having needle storing structure

Abstract

A hand pump includes a receptacle having a chamber and a mouth, a piston slidably engaged in the receptacle for generating a pressurized air, a piston rod attached to the piston, and a hand grip attached to the piston rod for moving the piston relative to the receptacle, the hand grip includes a compartment formed in the hand grip for receiving a needle device. The hand grip includes an extension attached to the piston rod, and a space formed in the extension and communicating with the compartment of the hand grip for engaging with the needle device. A cover is attached to the hand grip for enclosing the hand grip and for shielding and protecting the needle device.

I claim: 
     
         1 . A hand pump comprising:
 a receptacle including a chamber formed therein, and including a mouth,   a piston slidably engaged in said chamber of said receptacle and movable relative to said receptacle for generating a pressurized air,   a piston rod attached to said piston,   a hand grip attached to said piston rod for moving said piston relative to said receptacle, said hand grip including a compartment formed in said hand grip, and   a needle device received and engaged in said compartment of said hand grip.   
     
     
         2 . The hand pump as claimed in  claim 1 , wherein said hand grip includes an extension extended therefrom and attached to said piston rod. 
     
     
         3 . The hand pump as claimed in  claim 2 , wherein said hand grip includes a space formed in said extension of said hand grip and communicating with said compartment of said hand grip for receiving and engaging with said needle device. 
     
     
         4 . The hand pump as claimed in  claim 1 , wherein said hand grip includes a cover attached to said hand grip for enclosing said compartment of said hand grip and for shielding and protecting said needle device. 
     
     
         5 . The hand pump as claimed in  claim 1 , wherein said hand grip includes at least one reinforcing fin extended into said compartment of said hand grip for reinforcing said hand grip.
