Backhoe Hook Mounting Assembly

Abstract

A backhoe bucket lifting hook assembly has a hook device loop directly mounted on a link pivot pin of a backhoe assembly, with the hook loop engaging spacers on each side of the hook loop to position the hook device between spaced-apart members on which the pin is rotatably mounted.

The inventor claims:  
     
         1 . In a lifting hook assembly for a backhoe bucket apparatus having a link pin pivotally mounting a bucket, the combination comprising: 
 a hook device adapted to support loads for movement by the lifting hook assembly,    said hook device having an upper portion adapted to be rotatably disposed about said link pin, with said upper portion being in direct engagement with the link pin,    whereby loads applied to the hook device are borne directly by the pivot pin.    
     
     
         2 . A lifting hook assembly according to  claim 1  wherein said upper portion defines a loop to fit about said link pins, 
 said link pin is disposed between spaced-apart bucket assembly members, and  
 two tubular spacers are disposed one on each side of said hook device upper portion to position the hook device and to space apart said bucket assembly members.  
 
     
     
         3 . A lifting hook assembly according to  claim 2 , wherein said bucket assembly members are spaced-apart hydraulic actuator arms.  
     
     
         4 . A lifting hook assembly according to  claim 2 , wherein the spaced-apart bucket assembly members are spaced-apart components of the backhoe bucket.  
     
     
         5 . A lifting hook assembly according to  claim 1 . wherein: 
 said hook device is of enlarged size and adapted to support relatively large-sized flexible elongated support members for engagement with substantial loads to be moved.    
     
     
         6 . An assembly combination according to  claim 1 , wherein: 
 the flexible elongated member comprises (a) a chain, (b) a strap, (c) a nylon sling.    
     
     
         7 . An assembly according to  claim 5 , wherein: 
 said relatively large flexible elongated support member comprises (a) a chain, (b) a strap, (c) a nylon sling.    
     
     
         8 . A lifting hook assembly according to  claim 1 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper hook device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.    
     
     
         9 . A lifting hook assembly according to  claim 2 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper hook device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.    
     
     
         10 . A lifting hook assembly according to  claim 4 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper hook device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.    
     
     
         11 . A lifting hook assembly according to  claim 5 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper hook device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.    
     
     
         12 . A lifting hook assembly for a backhoe bucket apparatus having a link pin pivotally mounting a bucket, with a combination comprising: 
 a hook device adapted to support loads for movement by the lifting hook assembly,    said hook device having an upper portion defining a loop to fit about said link pin with the upper portion in direct engagement with the link pin,    said pivot pin being mounted between spaced-apart bucket actuator arms, and    two tubular spacers disposed on said link pin, with one spacer on each side of said hook device upper portion to position the hook device and to space apart said bucket assembly arms.    
     
     
         13 . A lifting hook assembly according to  claim 12 , wherein: 
 said pivot pin is also mounted between spaced-apart components of the bucket assembly.    
     
     
         14 . A lifting hook assembly combination of  claim 12 , wherein: 
 said hook device is of enlarged size and adapted to support relatively large-sized flexible elongated support members for engagement with substantial loads to be moved.    
     
     
         15 . A lifting hook assembly according to  claim 5 , wherein: 
 the flexibly elongated member comprises (a) a chain, (b) a strap, (c) a nylon sling.    
     
     
         16 . An assembly according to  claim 12 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper hook device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.    
     
     
         17 . A lifting hook assembly according to  claim 10 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper hook device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.    
     
     
         18 . A lifting hook assembly according to  claim 12 , and further including: 
 a closure member pivotally mounted on the upper hook device portion and extending across an opening between the upper device portion and an end portion of the hook device lower portion for entry of said elongated flexible support member and for prevention of disengagement thereof from the hook device.
