Extension system for mechanical stilts

Abstract

An extension is provided for a standard mechanical stilt that is interfitted or telescoped between upper frame members and lower frame members of the standard mechanical stilt to thereby greatly increase the desired working length of the mechanical stilt. The extension consists of the same cross-sectional profiles as the standard stilt. The extension member may be interlocked with the standard stilt at any desired length. The extension frame has shock absorbing springs incorporated therein.

1 . A standard mechanical stilt and extension frame combination, wherein said standard mechanical stilt includes upper and lower frame members which normally interfit with each other and having means thereon for adjusting a length between said upper and lower frame members, said extension frame having upper and lower frame members, said upper frame members having means thereon for interfitting with said upper frame members of said standard mechanical stilt and said extension frame further means thereon for interfitting said lower frame members on said extension frame with said lower frame members on said standard stilt. 
   
   
       2 . The standard mechanical stilt and extension frame member combination of  claim 1  including spring shock absorbers on said extension frame. 
   
   
       3 . The standard mechanical stilt and extension frame member combination of  claim 1  including locking means on said interfitting upper and said interfitting lower frame members. 
   
   
       4 . The standard mechanical stilt and extension frame member combination, wherein cross-sectional profiles of said standard stilt frame members and said extension frame members match each other.
