Abstract

Device for correcting the trajectory of projectiles in a weapon replica The invention relates to a trajectory correction device for a projectile exiting a cannon of a weapon replica, comprising a first pin ( 3 d ) forming a first boss ( 6 d ) for holding the projectile in the cannon, a second pin ( 3 g ) forming a second boss ( 6 g ) for holding the projectile in the cannon, the first and second pins being situated symmetrically on both sides of a vertical axis (XX) passing by the center (C) of the cannon.

Claims

exact text as granted — not AI-modified
1 . A trajectory correction device for a projectile exiting a cannon of a weapon replica, comprising a first pin forming a first boss for holding the projectile in the cannon, 
 wherein the device comprises a second pin forming a second boss for holding the projectile in the cannon, the first and second pins being symmetrically situated on both sides of a vertical axis passing by the center of the cannon, below a horizontal axis passing by the center of said cannon.    
   
   
       2 . The device according to  claim 1 , characterized in that the height of the first and second bosses in the cannon is adjustable.  
   
   
       3 . The device according to  claim 1 , characterized in that the first and second pins each comprise a screw with an adjustment knob.  
   
   
       4 . The device according to  claim 3 , characterized in that each screw of a pin pushes on a joint of the cannon in an elastic material, forming a boss.  
   
   
       5 . The device according to  claim 1 , characterized in that the first and second pins each comprise a lug fixed on an elastic strip.  
   
   
       6 . The device according to  claim 5 , characterized in that the cannon comprises, for each lug, an orifice for passage of the lug.  
   
   
       7 . The device according to  claim 5 , characterized in that the elastic strip is deformed by a control rod.  
   
   
       8 . The device according to  claim 5 , characterized in that the lug is made of an elastic material.  
   
   
       9 . The device according to  claim 5 , characterized in that the elastic strip is metal.  
   
   
       10 . The device according to  claim 1 , characterized in that the location of the bosses in the cannon is adjustable.  
   
   
       11 . The device according to  claim 10 , characterized in that the device comprises an adjustment knob fixed on the cannon, at equal distance from the two bosses.  
   
   
       12 . A projectile trajectory correction device for a weapon replica comprising: 
 a tubular cannon having a bore in which a projectile is received;    an elastic joint disposed in the bore in the cannon between the projectile and the cannon;    a plurality of bosses extending inwardly from the joint into the bore that bear against the projectile; and    wherein each one of the bosses is adjustable to affect trajectory of the projectile when the projectile is launched from the cannon.    
   
   
       13 . The device according to  claim 12 , further comprising a plurality of pins that each extends through a sidewall of the cannon and bears against one of the bosses, wherein the extent to which each pin can be extended is adjustable thereby enabling each boss to be adjusted by controlling how far the boss extends into the bore.  
   
   
       14 . The device according to  claim 13 , wherein the elastic joint is circular and bears against an inner surface of the cannon.  
   
   
       15 . The device according to  claim 12 , further comprising a plurality of screws that each threads into the cannon and bears against one of the bosses enabling each boss to be adjusted.  
   
   
       16 . The device according to  claim 12 , wherein each boss is integral with the elastic joint.  
   
   
       17 . A projectile trajectory correction device for a weapon replica comprising: 
 a tubular cannon having a bore in which a projectile is received;    a plurality of bosses extending inwardly into the bore that bear against the projectile;    a cannon support in which the cannon is received, the cannon being rotatable relative to the cannon support; and    a knob extending through the aperture and fixed to the cannon that is manipulable by a user to rotate the cannon relative to the cannon support to move the bosses in unison therewith.    
   
   
       18 . The device according to  claim 17 , wherein each boss extends inwardly from the cannon, the knob extends outwardly from the cannon beyond the cannon support, and movement of the knob rotates the cannon relative to the cannon support to position the bosses relative to a vertical axis thereof.  
   
   
       19 . A projectile trajectory correction device for a weapon replica comprising: 
 a tubular cannon having a bore in which a projectile is received and an orifice in a sidewall thereof;    an axially extending elastic strip disposed alongside an exterior surface of the cannon that has a lug with a boss received in the orifice that projects into the bore; and    an axially adjustable control rod that cooperates with the elastic strip to selectively control how far the boss projects into the bore.    
   
   
       20 . The device according to  claim 19 , further comprising a cannon support in which the cannon is received, and wherein the control rod and elastic strip slidably overlap one another and have at least a portion of where the control rod and elastic strip overlap being disposed between the cannon and the cannon support.  
   
   
       21 . The device according to  claim 20 , wherein the control rod is axially extended or retracted to change how far the boss projects into the bore in the cannon.
