Resilient loader attachment system

Abstract

A resilient loader attachment system for allowing a loader attachment device to be utilized without the direct weight of the tractor placed upon a work area. The resilient loader attachment system includes an attachment structure for securing to a loader of a tractor, a frame extending from the attachment structure, a pair of upper guide plates and a pair of lower guide plates movably positioned within the frame in a vertical manner, a plurality of compression springs or dampener cylinders positioned between the frame and the guide plates, and an attachment device attached to the distal ends of the guide plates. The guide plates are able to move upwardly and downwardly, and rotate within the frame for reducing the effectively force of the loader and tractor during the usage of an attachment device such as but not limited to a concrete screed.

         7 . The resilient loader attachment system of  claim 4 , wherein said means for applying a vertical force is comprised of a plurality of compression springs.  
     
     
         8 . The resilient loader attachment system of  claim 7 , including a plurality of threaded shafts extending through said compression springs with interiorly threaded nuts attached to the distal ends thereof for allowing adjustment of a vertical force applied by said compression springs.  
     
     
         9 . The resilient loader attachment system of  claim 1 , wherein said at least one upper guide plate and said at least one lower guide plate each include at least one bushing for slidably surrounding said plurality of guide shafts.  
     
     
         10 . The resilient loader attachment system of  claim 9 , wherein said plurality of guide shafts are comprised of a pair of guide shafts.  
     
     
         11 . A resilient loader attachment system, comprising: 
 an attachment structure for attaching to a loader of a tractor;    a frame extending from said attachment structure, wherein said frame includes at least one upper plate, at least one middle plate, and at least one lower plate;    a plurality of guide shafts extending vertically within said frame and pivotally attached to said at least one middle plate by a pivot bearing;    at least one upper guide plate slidably positioned upon said plurality of guide shafts between said at least one upper plate and said at least one middle plate;    at least one lower guide plate slidably positioned upon said plurality of guide shafts between said at least one lower plate and said at least one middle plate; and    at least one upper arm and at least one lower arm extending from said at least one upper guide plate and said at least one lower guide plate respectively for receiving an attachment device.    
     
     
         12 . The resilient loader attachment system of  claim 11 , including a means for applying a vertical force upon said at least one upper guide plate and said at least one lower guide plate.  
     
     
         13 . The resilient loader attachment system of  claim 12 , wherein said means for applying a vertical force applies both an upward and a downward vertical force upon said at least one upper guide plate and said at least one lower guide plate.  
     
     
         14 . The resilient loader attachment system of  claim 13 , wherein said at least one upper guide plate is comprised of a pair of upper guide plates and said at least one lower guide plate is comprised of a pair of lower guide plates.  
     
     
         15 . The resilient loader attachment system of  claim 14 , wherein said means for applying a vertical force is comprised of a plurality of dampener cylinders.  
     
     
         16 . The resilient loader attachment system of  claim 14 , wherein said means for applying a vertical force is comprised of a plurality of hydraulic cylinders.  
     
     
         17 . The resilient loader attachment system of  claim 14 , wherein said means for applying a vertical force is comprised of a plurality of compression springs.  
     
     
         18 . The resilient loader attachment system of  claim 17 , including a plurality of threaded shafts extending through said compression springs with interiorly threaded nuts attached to the distal ends thereof for allowing adjustment of a vertical force applied by said compression springs.  
     
     
         19 . The resilient loader attachment system of  claim 11 , wherein said at least one upper guide plate and said at least one lower guide plate each include at least one bushing for slidably surrounding said plurality of guide shafts.
