Abstract
A dental handpiece with a gripping sleeve-like base member which is detachably connected with a headpiece mounting a work tool, a connecting sleeve of the headpiece being insertable into the power-take off end of the base member, wherein a roll body is radially movably supported in each of one or more cutouts in the base member wall, inwardly extending therethrough with a portion of its volume, which is movable through the intermediary of a coupling element movably arranged on the base member, and which includes an inclined plane for the engagement with the roll body under the assumption of a clamping fit in contact against the connecting sleeve.
Claims34
Dental headpiece comprising a gripping sleeve-like circular base member;
- a headpiece having a work tool supported thereon detachably connected to said sleeve-like base member;
- said headpiece having a connecting sleeve insertable into a bore in an end of said base member;
- said base member having at least one cutout therein in its circular sleeve wall;
- a roll body being radially movably supported in each of said cutouts so as to have a portion of the volume of the roll body extending inwardly therethrough;
- a sleeve-like coupling element surrounding said base member and being movably arranged relative to said base member, said coupling element including an inclined cam surface for engaging said roll body and radially moving said roll body, when said coupling element is moved relative to said base member, to cause said roll body to assume a clamping fit in contact against said connecting sleeve;
- and a separate spring means for resiliently bearing between said base member and said connecting sleeve for securing a clamping fit of said roll body to prevent inadvertent loosening of said roll body relative to said connecting sleeve of the headpiece.
