Problems solved by technology

Since the head structure is not supported in the area of ​​its outer edge in the coupled state, the area of ​​the outer edge cannot contribute to the transfer of external loads to the base structure
As a result, the coupling element must transfer a significant portion of the external load
In addition, due to the arrangement of the coupling element in the central region of the head structure, mechanical torques associated with external loads will result in relatively large forces on the coupling element

Embodiment Construction

[0030] figure 1 A shaving appliance 1 is shown, which is a practical example of a personal care appliance according to the invention. The shaving appliance 1 comprises a main body 2 intended to be held by a user of the shaving appliance 1 and a head 3 intended to be pressed against the skin area to be subjected to shaving. exist figure 1 , the shaving appliance 1 is shown in normal orientation, and in the following, indications such as top and bottom should be understood in the normal orientation.

[0031] On the top side, the body 2 comprises a body part 4 . On the bottom side the head 3 comprises a head part 5 and on the top side the head 3 comprises a plurality of rotary shaving units 6, three in the example shown. The shaving appliance 1 further comprises a coupling assembly 10 located at the joint between the main body 2 and the head 3 for releasably coupling the main body 2 and the head 3 . The central axis of the coupling assembly 10 is used for figure 1 The dotted...

Abstract

The application relates to a coupling assembly for use in a personal care appliance. Provided is a coupling assembly, which includes a coupling element and a retaining member, for releasably couplinga body (2) and a head of a personal care appliance. One of the coupling element and the retaining member comprises at least one cam element (55) and another of the coupling element and the retaining member comprises at least one notch (46). Both the cam element (55) and the notch (46) have two oppositely sloped surfaces (48; 57). In a coupled position of the coupling assembly, the cam element (55)and the notch (46) only contact each other at two sides through their sloped surfaces (48; 57) at the position of a contact portion (55a) at a base of the cam element (55) and an associated contact portion (46a) of the notch (46) at an open side of the notch (46).

Description

technical field [0001] The present invention relates to a coupling assembly configured for use in a personal care appliance at a junction between a body and a head of a personal care appliance to releasably couple the body and the head, wherein the coupling The assembly includes a coupling element and a retaining member, the retaining member has a receiving space configured to receive and accommodate the coupling element, wherein one of the coupling element and the retaining member includes at least one cam element, the at least one cam element The coupling assembly protrudes in the direction of the central axis, and the other of the coupling element and the retaining member includes at least one notch configured to receive and accommodate the at least one cam element to form at least one coupling combination, and wherein, in the peripheral direction around the central axis, the at least one cam element has two oppositely inclined surfaces in the direction from the base of the...
