Abstract
Abstract An auxiliary handle for attachment to the primary handle of a conventional shovel includes upper and lower handle portions which are connected together for length adjustable sliding movement relative to one another. Coacting stops on the upper and lower handle portions limit the extent of relative sliding movement therebetween. A biasing mechanism urges the upper handle portion downwardly toward the retracted position thereof. Furthermore, the range of extendible lengths for the auxiliary handle may be adjusted to accommodate different users.

Total Claims: 12
Claim 1
Independent Claim
145 words
An auxiliary handle for a shovel having an elongated primary handle with upper and lower ends and a shovel blade at the lower end thereof, said auxiliary handle comprising elongated upper and lower handle portions, each having respective upper and lower ends, a pivotal mounting bracket on the lower end of said lower handle portion and adapted for securement to a primary handle at a selected position along the length of the primary handle for pivotally connecting the lower handle portion to the primary handle, means for connecting said handle portions together for length adjustable sliding movement relative to one another, coacting stop means on said upper and lower handle portions for limiting sliding movement of the upper handle portion relative to the lower handle portion to extended and retracted positions thereof, and means for biasing said upper handle portion to the retracted position thereof.
Claim 2
Dependent Claim
145 words
An auxiliary handle for a shovel having an elongated primary handle with upper and lower ends and a shovel blade at the lower end thereof, said auxiliary handle comprising elongated upper and lower handle portions, each having respective upper and lower ends, a pivotal mounting bracket on the lower end of said lower handle portion and adapted for securement to a primary handle at a selected position along the length of the primary handle for pivotally connecting the lower handle portion to the primary handle, means for connecting said handle portions together for length adjustable sliding movement relative to one another, coacting stop means on said upper and lower handle portions for limiting sliding movement of the upper handle portion relative to the lower handle portion to extended and retracted positions thereof, and means for biasing said upper handle portion to the retracted position thereof.
Claim 3
Dependent Claim
