Embodiment Construction

[0048] In the following description, the same or similar elements are given the same reference numerals.

[0049] Figures 1 to 4 show an electrical appliance 10, such as a GSM-type mobile phone, according to the prior art.

[0050] The telephone 10 has a protective housing 12 within which are located the elements that enable the operation of the telephone. Of these elements only the display screen 14 is shown.

[0051] For ease of understanding, inner and outer orientations are taken with respect to the inside and outside of the protective housing 12, respectively.

[0052] To facilitate assembly of the components, the protective housing 12 has a distinct bottom shell member 16 and a top shell member 18 . Thus, the components can be mounted in housings, the two housings being joined together so that the housing 12 is closed.

[0053] The top shell member 18 has an opening or window 20 closed by a generally planar shaped body 22 of transparent material. Opening 20 is create...

Abstract

The invention proposes a protective casing (12) for an electronic appliance (10) of the type which has a shell (18) in which there is produced an opening (20) closed off by a body (22) made from transparent material with a general flat shape, of the type in which at least one internal peripheral annular fixing area (30) of the transparent body (22) is fixed to a facing area (32) of the periphery of the opening (20) by fixing and / or positioning means (34) with the interposing of a first decorative cladding (38) between the peripheral fixing area (30) of the transparent body (22) and the fixing and / or position means (34), characterized in that the peripheral fixing area (30) is inclined with respect to the overall plane of the transparent body (22). The invention also proposes a method and tool for manufacturing such a casing.

Description

technical field [0001] The invention relates to a protective casing of an electrical appliance. [0002] The invention relates more particularly to a protective housing for an electrical appliance having a housing with an opening closed by a body made of transparent material, generally planar in shape. [0003] The invention also relates to an electrical appliance having such a housing. Background technique [0004] Such protective casings are used, for example, in GSM-type mobile phones. [0005] The protective enclosure in fact protects the parts of the electrical appliance, such as key extenders and switches, whose actuation changes the state of the electricity of the control circuit. In the case of mobile phones, the protective housing must also protect the display screen, which provides the interface between the appliance and the user. [0006] For this purpose, the housing usually has an opening or window closed by a generally planar shaped body made of transparent ...
