Embodiment Construction

[0025] Figure 1a and Figure 1b Shown is a protector element or cap of conventional design suitable for use in a shaving appliance (not shown) as a protector for a movable hair cutting element of the appliance, the protector element or The cap will be referred to as the known cap 5 hereinafter. Shaving appliances comprising such caps are generally known, and therefore details of such appliances will not be described further. For the sake of completeness, as previously mentioned, it is noted that an example of such an appliance can be found in US 4,168,570. In general, a shaving appliance comprises a main body for a user of the shaving appliance to hold and a head comprising at least one shaving unit, wherein a shaving unit is defined as a unit comprising a combination of a cap and a movable hair cutting element. Caps are usually made of metal.

[0026] The known cap 5 is generally cup-shaped, comprising a disc-shaped base 10 and an annular wall 20 . The disc-shaped base 1...

Abstract

A guard element (4) for use in a hair cutting unit as a guard of a movable hair cutting element of the hair cutting unit has a disc-shaped base (10) and an annular wall (20) comprising a main part (21) extending from the periphery of the base (10), and a flange-shaped part (22) comprising an outwardly bent section (24).The annular wall (20) is reinforced on the basis of at least one of a design where a smallest inner periphery of the flange-shaped part (22) has a diameter which is smaller than a diameter of a largest inner periphery of a straight section (23) of the main part (21) connected to the periphery of the base (10), and a design where a free end section (25) of the flange-shaped part (22) is at least partially bent. In an embodiment, at least a portion of the main wall part (21) of the guard element (4) tapers inwardly in a direction along a central axis (11) of the disc-shaped base (10), from the disc-shaped base (10) to the flange-shaped wall part (22), such that the flange-shaped wall part (22) is enlarged with respect to a flange-shaped wall part (22) of a guard element (5) not having the tapered shape of the main wall part (21), resulting in increased stiffness and an increased resonant frequency of the guard element (4).

Description

technical field [0001] The invention relates to a protector element for use in a hair cutting unit as a protector for a movable hair cutting element of the hair cutting unit, the protector element being generally cup-shaped and comprising a disc-shaped base and an annular wall, wherein The disc-shaped base includes a central axis and a peripheral section that is curved when viewed in a central cross-section including the central axis of the protector element, and wherein the annular wall includes a main body portion and a flange-shaped portion, wherein the annular wall The main body portion has a substantially vertical orientation with respect to the disc-shaped base, and the main body portion includes a straight section that is not curved when viewed in central cross-section, and the straight section connects to the peripheral section of the disc-shaped base, and wherein the flange-shaped portion of the annular wall includes an outwardly bent section that bends outward relati...
