Abstract: An attachment for a personal care device, such as a shaving or trimming device, is configured to be releasably coupled to a coupling structure of the personal care device by a coupler. The coupler includes a shaft having at least one coupling recess on the circumferential surface thereof. The coupling recess has a central portion and first and second side portions arranged on opposite sides of the central portion. The coupling recess also includes a sloped surface arranged in at least the central portion. When the attachment is coupled to the coupling structure, the sloped surface is engaged by a spring of the coupling structure. At least one of the first and second side portions of the coupling recess is recessed relative to the sloped surface, seen in a direction parallel to the central axis of the shaft.

Abstract: The invention relates to an attachment (2) for a personal care device (1), such as a shaving or trimming device. The attachment (2) is adapted to be releasably coupled to a coupling structure (11) of the personal care device by means of a coupling member (10). The coupling member (10) comprises a shaft-like element (6) having at least one coupling recess (7) on the circumferential surface (8) thereof. This coupling recess (7) has a central portion and first and second side portions (18, 20) arranged on opposite sides of the central portion. It comprises a sloped surface (15) arranged in at least the central portion. When the attachment (2) is coupled to the coupling structure (11), the sloped surface is engaged by a spring of the coupling structure (11). At least one of the first and second side portions (18, 20) of the coupling recess (7) is recessed relative to the sloped surface (15), seen in a direction parallel to the central axis (13) of the shaft-like element (6).
