Abstract
A power tool comprising a drive shaft for driving a tool, a recess at a free end of the drive shaft, and a detachable securement flange having a securement section on a side facing the drive shaft is disclosed. The securement section is form-fitted for insertion into the recess of the drive shaft and comprises a flange section on the opposite side, wherein the tool comprises a respective securement opening which is adapted to the shape of the securement section of the securement flange for form-fit securement of the securement opening of the tool to the securement section.
Claims22
A power tool comprising:
- a drive shaft for driving a tool;
- a recess provided at a free end of said drive shaft and having a wall;
- a detachable securement flange having a securement section on a first side facing the drive shaft, the securement section having a wall and being form-fitted for insertion into the recess of the drive shaft;
- said wall of said recess is adapted to receive a compressive force from said wall of said securement section;
- said wall of said securement section is adapted to receive a compressive force from said wall of said recess;
- and
- a securement opening provided on said tool and being mated to the shape of said securement section of said securement flange for form-fit securement of said tool to said drive shaft, when said securement section of said flange engages said securement opening of said tool and said recess of said drive shaft.
A power tool comprising:
- a drive shaft for driving a tool;
- a recess provided at a free end of said drive shaft;
- a detachable securement flange having a securement section on a first side facing the drive shaft, the securement section being form-fitted for insertion into the recess of the drive shaft;
- a securement opening provided on said tool and being mated to the shape of said securement section of said securement flange for form-fit securement of said tool to said drive shaft, when said securement section of said flange engages said securement opening of said tool and said recess of said drive shaft;
- and
- said securement section of said securement flange comprises a first region being mated to the recess of said drive shaft for positive engagement therewith, and wherein said securement section further comprises a second region being mated to said securement opening for positive engagement therewith, wherein said first and second regions are of different configuration.
A drive shaft in a power tool, comprising a recess at a free end of said drive shaft, the recess being mated to a securement section of a detachable securement flange to provide a form-fit securement of a tool to said drive shaft when said securement flange positively engages said recess of said drive shaft and a securement opening of said tool, wherein said form-fit securement inhibits angular rotation between said recess and said securement section.
A securement flange for form-fit securement of a tool to a free end of a drive shaft of a power tool, said flange comprising:
- a securement section, the outer contour of which is mated to an inner contour of a securement opening of said tool and to a recess provided at said free end of said drive shaft, thereby allowing a form-fit between said securement opening of said tool, said securement flange and said recess of said drive shaft;
- the recess having a wall;
- the securement section having a wall;
- said wall of said recess is adapted to receive a compressive force from said wall of said securement section;
- and
- said wall of said securement section is adapted to receive a compressive force from said wall of said recess.
A securement flange for form-fit securement of a tool to a free end of a drive shaft of a power tool, said flange comprising:
- a securement section, the outer contour of which is mated to an inner contour of a securement opening of said tool and to a recess provided at said free end of said drive shaft, thereby allowing a form-fit between said securement opening of said tool, said securement flange and said recess of said drive shaft;
- and
- wherein said securement section comprises a first region being form-fitted to said recess of said drive shaft, and wherein said securement section further comprises a second region being form-fitted to said securement opening of said tool.
