Toothbrush

摘要

Toothbrush having a brush part (32) and a hollow handle part (34) with an axial plain bearing (40), a coupling rod (36) which is axially displaceable in the handle part (34) and can be connected to the brush part (32) and projects into the hollow handle part, further having a restoring spring (86), which is prestressed on the coupling rod (36) in the direction of the handle part (24), and a catch device (46, 48) for rotational locking between the coupling end of the brush part (32) and the handle part (34). A securing device (88) serves for preventing unintentional axial movement of the coupling rod (36). A first part of the securing device (locking block 82) is assigned to the coupling rod (36) and a second part of the same (locking lever 90) is assigned to the handle part (34). The second part is movable between a securing position and a releasing position and is prestressed by means of a spring (98; 238) in the direction of the securing position. An actuating device (elastic wall portion 120; elastic terminal piece 248) in the wall of the hollow handle part (34) serves for actuating the second part of the securing device (88). An axial relative movement of the brush part with respect to the handle part to release the rotationally fixed connection of both parts is thereby reliably prevented.
