Pneumatic dent puller

Abstract

A pneumatic dent puller for pulling and repairing dented metal panels, parts and structures of automotive vehicles includes a housing for enclosing therein an air hammer, a handle, a manually operable trigger and a threaded member attached to the housing. The threaded member is threaded into a hole formed on the surface to be pulled and as the technician simultaneously depresses the trigger and slightly pulls on the handle, the dented surface is pulled out to its original position by the combined actions of the air hammer and the threaded member.

1 . A pneumatic dent puller for pulling out a dented part of an automotive vehicle body panel, body part or structure, comprising: 
 an elongated housing enclosing therein a pneumatic hammer, a handle attached to the housing, and a manually operable trigger on the handle;    means for interconnecting the housing to a pressurized flow of air;    a threaded member securable to the nose of the housing and capable of insertion into a hole formed on the surface of the dented part; and    the technician manually squeezing the trigger and applying a pulling force on the handle thereby actuating the pneumatic hammer to act in the direction opposite of the threaded member so that the dented part can be pulled out by threaded member.    
   
   
       2 . The pneumatic dent puller of  claim 1  wherein the threaded member is replaceable on the nose of the housing.  
   
   
       3 . The pneumatic dent puller of  claim 2  further comprising a u-shaped tool for attachment to the threaded member so that the u-shaped tool can be hooked onto the dented part for pulling by the pneumatic hammer.  
   
   
       4 . The pneumatic dent puller of  claim 3  further comprising a right-angled tool for attachment to the threaded member so that the right-angled tool can be hooked about the dented part for pulling by the pneumatic hammer.  
   
   
       5 . The pneumatic dent puller of  claim 4  wherein the u-shaped tool includes a first threaded stud attachable to the nose of the housing of the pneumatic hammer.  
   
   
       6 . The pneumatic dent puller of  claim 5  wherein the u-shaped tool includes a second threaded stud attachable to the nose of the housing of the pneumatic hammer.  
   
   
       7 . The pneumatic dent puller of  claim 6  further comprising an incremental pull distance adjustment means mounted on the pneumatic hammer and manually manipulable to set the distance of each individual pull during a specific pulling operation.  
   
   
       8 . The pneumatic dent puller of  claim 7  wherein the incremental pull distance adjustment means includes a selectively movable depth slider switch mounted on the housing and capable of selective manual manipulation to set the pull distance for each pulling operation.  
   
   
       9 . A pneumatic dent puller for pulling out a dented portion of an automotive vehicle body panel, part or structure, comprising: 
 an elongated housing enclosing therein a pneumatic hammer, a handle attached to the housing and a manually operable trigger mounted on the handle;    means for interconnecting the housing to a pressurized flow of air;    a threaded member securable to the nose of the housing and capable of insertion into a hole formed on the surface of the dented portion;    an incremental pull distance adjustment means mounted on the pneumatic hammer and manually manipulable to set the distance of each individual pull during a specific pulling operation; and    the technician applying a pulling force on the handle while manually squeezing the trigger thereby actuating the pneumatic hammer to act in the direction opposite of the threaded member so that the dented portion can be pulled out to the original position by the threaded member.    
   
   
       10 . The pneumatic dent puller of  claim 9  further comprising a u-shaped tool for attachment to the threaded member so that the u-shaped tool can be hooked onto the dented portion for pulling by the pneumatic hammer.  
   
   
       11 . The pneumatic dent puller of  claim 10  further comprising a right-angled tool for attachment to the threaded member so that the right-angled tool can be hooked about the dented portion for pulling by the pneumatic hammer.  
   
   
       12 . The pneumatic dent puller of  claim 11  wherein the u-shaped tool includes a first threaded stud attachable to the nose of the housing of the pneumatic hammer.  
   
   
       13 . The pneumatic dent puller of  claim 12  wherein the right-angled tool includes a second threaded stud attachable to the nose of the housing of the pneumatic hammer.  
   
   
       14 . The pneumatic dent puller of  claim 13  wherein the incremental pull distance adjustment means includes a selectively slidable depth slider switch mounted on the housing and capable of selective manual manipulation to set the pull distance for each pulling operation.
