Holding device for spare string trimmer line spools with slotted inner cavities

Abstract

The holding device comprises a clamp body attached to a pair of support arms. Each support arm has a round lug near its upper surface that engages a slot in the inner cavity of the trimmer line spool. The holding device is held on the shaft of a string trimmer by a pair of resilient clamp arms.

I claim:  
     
         1 . A device for holding a spare string trimmer spool on a string trimmer, comprising: 
 (a) a clamping means to hold the device on the string trimmer's shaft, and    (b) a pair of support arms that utilize round lugs to engage the grooves in the spare spool of trimmer line's inner cavity as a means of holding the spare spool of trimmer line in place    whereby the spare spool of trimmer line is securely held on the string trimmer during use of the string trimmer and can be conveniently removed from the spare spool holder and put into use on the string trimmer when required.    
     
     
         2 . The holder of  claim 1  wherein the clamping means comprises a pair of clamp arms that grip the string trimmer's shaft after the shaft is pushed between the clamp arms.  
     
     
         3 . The holder of  claim 1  wherein the clamping means comprises a split collar and threaded fastener.  
     
     
         4 . The holder of  claim 1  wherein the support arms each have an outer surface that is substantially curved to fit inside the spare spool of trimmer line's inner cavity.  
     
     
         5 . The holder of  claim 1  wherein a cross bar spans the gap between the support arms to prevent deflection of the support arms  
     
     
         6 . The holder of  claim 1  wherein the loose ends of trimmer line are pushed into gaps between clips and the clamp body as a means of keeping the loose ends of trimmer line from unwinding from the spool while the trimmer is in use.
