Toy gun

Abstract

To avoid the situation, in which a gas pressure to be used for shooting a bullet from a loading chamber is partially lost, a toy gun in which a paint bullet charged in the loading chamber may be reliably shot with gas under a relatively low pressure is provided. A gas flow control mechanism is arranged movably with respect to a movable member and forms a first gas passage for guiding the gas into the loading chamber and a second gas passage for guiding the gas to pressure receiving portions. For a period in which gas supply controllers take a gas supply state as the movable member advances, the gas flow control mechanism transfers from a state, in which the gas passage is opened whereas the gas passage is closed to supply the gas to the loading chamber through the gas passage, to a state, in which the gas passage is closed whereas the gas passage is opened to apply the gas to the pressure receiving portions through the gas passage, so that the movable member is moved back and forth thereby to make preparations for supplying the ballet P from a magazine to the loading chamber.

What is claimed is:  
     
         1 . A toy gun comprising: 
 a frame including a barrel, a loading chamber formed in said barrel, a magazine for holding bullets to be charged in said loading chamber, and a trigger;    a movable member arranged with a pressure receiving portion in said frame and made movable in a first direction toward said loading chamber and in a second direction opposed to the first direction;    a drive mechanism for moving said movable member in said first direction in response to the operation of said trigger;    a gas supply controller connected to a gas outlet passage for taking a gas supply state, in which gas is supplied, as said movable member moves in said first direction; and    a gas flow control mechanism arranged movably with respect to said movable member and forming a first gas passage for guiding the gas into said loading chamber and a second gas passage for guiding the gas to said pressure receiving portion, whereby, for a period in which said gas supply controller takes said gas supply state as said movable member moves in said first direction, said gas flow control mechanism transfers from a first state, in which said first gas passage is opened whereas said second gas passage is closed to supply the gas obtained in said gas outlet passage to said loading chamber through said first gas passage, to a second state, in which said first gas passage is closed whereas said second gas passage is opened to apply the gas obtained in said gas outlet passage to said pressure receiving portion through said second gas passage, so that said movable member is moved in said second direction thereby to make preparations for supplying the ballet from said magazine to said loading chamber.    
     
     
         2 . A toy gun according to  claim 1 , 
 wherein the bullets to be held in the magazine are paint containing bullets for discharging paint when crushed.    
     
     
         3 . A toy gun according to  claim 1 , 
 wherein the movable member moves in the second direction while forming a variable capacity pressure chamber between the pressure receiving portion and the gas flow control mechanism.    
     
     
         4 . A toy gun according to  claim 1 , 
 wherein the gas flow control mechanism is constructed to include: a gas passage forming member for forming the first gas passage and the second gas passage; and a movable valve arranged movably in said gas passage forming member for taking selectively a position to open said first gas passage and to close said second gas passage and a position to close said first gas passage and to open said second gas passage.    
     
     
         5 . A toy gun according to  claim 1 , 
 wherein the gas supply controller includes: a gas chamber, into which the gas from the outside is introduced; and a control valve for taking, selectively according to the position of the movable member, a closed state to block the gas flow from said gas chamber to the gas outlet passage and an open state to establish the gas flow from said gas chamber to said gas outlet passage.    
     
     
         6 . A toy gun according to  claim 1 , 
 wherein said gas supply controller includes: an accumulation chamber for reserving the gas charged; and a control valve for taking, selectively according to the position of the movable member, a closed state to block the gas flow from said accumulation chamber to the gas outlet passage and an open state to establish the gas flow from said accumulation chamber to said gas outlet passage.
