Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
198 words
A tool handle adapted to telescope over the end of a pool pole, said handle having adjacent its distal end a pair of diametrally opposed first apertures, and having adjacent thereto and aligned therewith a pair of diametrally opposed second apertures, and a wishbone-like spring member positioned within said handle by a pair of outer opposed thumb buttons carried thereby and extending into said first apertures and by a pair of inner opposed locking buttons carried thereby and extending into said second apertures, said thumb buttons being greater in axial length than said locking buttons whereby a conjoint but partial depressing of said thumb buttons frees said locking buttons from said second apertures while said thumb buttons still extend into said first apertures, said spring member being freeable for removal from said handle by a conjoint and substantially full depressing of said thumb buttons to free the same from said first apertures, said handle being attachable to said pool pole by means comprising a pair of diametrally opposed third apertures formed in said pole adjacent the distal end thereof and by said locking buttons which are adapted to extend through said third apertures and into said second apertures.
Claim 2
Dependent Claim
