Abstract
A telescoping hex head nut driver comprising a first hexagonal socket on a shank, a handle attached to said shank, with smaller (inner) hexagonal sockets and shanks telescoping within the first hexagonal socket and shank. The inner sockets can be extended to engage smaller hex head nuts and means are provided in the handle to extend and retract the inner sockets.
Claims7
A telescoping hexagonal nut driver having a plurality of hexagonally shaped heads, each forming a socket of a different size and adapted to engage correspondingly sized hexagonal nuts for driving said nuts by rotational movement, comprising:
- a first hexagonal socket means having a hollow shank;
- a handle surrounding a portion of said shank on said first socket means, said handle having an axial slot open at the forward end;
- a second hexagonal socket means smaller than said first hexagonal socket means for positioning within said first socket means in sliding engagement with the inner side walls of said first hexagonal socket means, said second socket means having a hollow shank and telescoping outwardly beyond said first hexagonal socket means;
- first positioning means in sliding engagement on said handle and surrounding more than half of said handle;
- first connection means extending through said slot in said handle behind said first socket means shank and connecting said first positioning means and the shank of said second socket means so that said first positioning means and second socket means shank are slidable together for moving said second socket means outwardly beyond said first socket means;
- a third hexagonal socket means smaller than said second hexagonal socket means for positioning within said second socket means in sliding engagement with the inner side walls of said second hexagonal socket means, said third hexagonal socket means having a shank and telescoping outwardly beyond said second socket means;
- second positioning means in sliding engagement on the outer periphery of said handle and surrounding more than half of said handle;
- and
- second connection means extending through said handle slot behind said second socket means shank and connecting said second positioning means and the shank of said third hexagonal socket means so that said second positioning means and third socket means shank are slidable together for moving said third socket means outwardly beyond said second socket means.
