Abstract
This invention is a quick connecting and disconnecting assembly for standard dental handpieces that are normally connected to a supply line by base nut sleeves that are screwed onto the threaded end of such handpieces. This is accomplished by simply replacing the interiorly threaded base nut on the supply line with a base locking sleeve having j-shaped slots in the outer end thereof and telescoping this over an interiorly threaded connector sleeve with exterior lugs thereon mounted on the threaded end of the handpiece so that the lugs can engage the j-shaped slots.

A method of converting a pre-existing dental handpiece to a quick connect and disconnect dental handpiece by the installation of quick connect and disconnect means, said pre-existing dental handpiece having a threaded end portion adapted to receive a threaded nut sleeve, said sleeve engaging a connector attached to the end of a supply line, said method comprising:
- removing said base nut sleeve from said threaded portion of said handpiece and separating said connector therefrom;
- screwing a connector sleeve having at least one outwardly projecting locking pin on the exterior thereof onto said threaded end portion of said handpiece;
- removing said base nut sleeve from said supply line and said connector and replacing the same with a base locking sleeve having at least one j-shaped slot in the end thereof;
- sliding said base locking sleeve over said connector sleeve;
- and twisting said base locking sleeve to engage said at least one locking pin in said at least one j-shaped slot whereby said pre-existing dental handpiece that is threadably connected to said supply line is converted to a quick connect and disconnect handpiece.
