Safety link for pneumatic nailers

Abstract

A pneumatic nailer includes a barrel with a nose portion connected to a front end thereof and a magazine is connected to the barrel so as to feed nails into the nose portion. A handle is connected to the barrel and a valve is received in the handle. The valve has a movable shaft which is in contact with a trigger and biased by a first spring. A safety link is movably connected to the barrel and located parallel to the nose portion. The safety link has a front end located shorter than the nose portion and a rear end of the safety link is pivotably connected to a first end of the trigger. The first end of the trigger is movable toward the nose portion relative to the movable shaft. A second spring biases the safety link in a direction that the safety link linearly moves. The front end of the safety link is shorter than the nose portion so that the user aims the object without interruption by the safety link.

1 . A pneumatic nailer comprising: 
 a safety link connected to a barrel or nose portion and movable along the nose portion, the safety link being biased by a spring and toward the barrel when a trigger is not yet pulled, the safety link being moved toward an object to be nailed when the trigger is pulled so as to eject a nail out from the nose portion.    
   
   
       2 . The nailer as claimed in  claim 1 , wherein the spring is directly connected between a top surface of the safety link and an outer periphery of the barrel, the spring is in an extended status.  
   
   
       3 . The nailer as claimed in  claim 1 , wherein the spring is connected between an inside of the safety link and an outer periphery of the barrel, the spring is in a compressed status.  
   
   
       4 . The nailer as claimed in  claim 1 , wherein the spring is connected between an inside of the trigger and an outer periphery of the barrel or a valve in the handle, an end of the trigger is pivotably connected to the safety link so that the spring is indirectly applied a force to move the safety link toward the barrel, when the trigger is pulled, the safety link is moved toward the object to be nailed.  
   
   
       5 . The nailer as claimed in  claim 1 , wherein the spring is connected between a shaft of the valve and the handle, the spring is in a compressed status, the shaft is connected to an inside of the trigger and an end of the trigger is pivotably connected to the safety link so that the spring is indirectly applied a force to move the safety link toward the barrel, when the trigger is pulled, the safety link is moved toward the object to be nailed.  
   
   
       6 . The nailer as claimed in  claim 1 , wherein the spring is connected between a flange extending from the barrel and the trigger, the spring is in a compressed status, the trigger is connected to the safety link so that the spring is applied a force to move the safety link toward the barrel, when the trigger is pulled, the safety link is moved toward the object to be nailed.  
   
   
       7 . The nailer as claimed in  claim 1 , wherein the spring is connected between a flange extending from the barrel and an inside of the safety link, the spring is in a compressed status, so that the spring is applied a force to move the safety link toward the barrel, when the trigger is pulled, the safety link is moved toward the object to be nailed.  
   
   
       8 . The nailer as claimed in  claim 1 , wherein the safety link is a single piece.  
   
   
       9 . The nailer as claimed in  claim 1 , wherein the safety link is composed of a plurality of pieces.  
   
   
       10 . The nailer as claimed in  claim 1 , wherein the spring can be an extendable spring, a compressible spring, a spring plate, a plastic plate, a fiber member, a rubber member and a foam member.  
   
   
       11 . The nailer as claimed in  claim 3 , wherein the nose portion is a single piece.  
   
   
       12 . The nailer as claimed in  claim 3 , wherein the nose portion is composed of a plurality of pieces.  
   
   
       13 . The nailer as claimed in  claim 2  or  3 , wherein the safety link is not connected to the trigger.  
   
   
       14 . The nailer as claimed in  claim 4  or  5 , wherein the trigger is a single piece.  
   
   
       15 . The nailer as claimed in  claim 4  or  5 , wherein the trigger is composed of a plurality of pieces.
