Abstract:
A hinged electronic device comprising a first part and a second part and a hinge adapting said parts foldingly to each other between a first and a second configuration, and which hinge comprises:an elongated hinge pin having a first end and a second end, and which hinge pin has on its outer surface a tapered section, in which it is tapered toward its second end,a tapered bowl comprising an inward tapering inner surface, and which has been arranged to receive said tapered section of hinge pin to touch its inner surface,a spring element for pressing said tapered section of hinge pin against the tapered inner surface of said tapered bowl in order to create a friction force resisting turning of the first part in relation to the second part andfirst means for arranging said tapered section to be turnable in relation to said inner surface and to be rubbing against said inner surface due to the effect of said spring element when the first and second parts are turned about the hinge between the first and second configuration in order to create a friction force remaining on a particular level and resisting the opening and closing of the device between the first and second configuration, said tapered section of the hinge pin and inner surface of the tapered bowl being the rubbing surfaces, whereinsaid electronic device comprises second means for enabling said rubbing surfaces to approach each other as a response to the wear of at least one of said rubbing surfaces, andsaid spring element has been arranged, as a response to the wear of at least one of said rubbing surfaces, to move said rubbing surfaces in relation to each other and toward each other in the direction of the hinge pin in order to maintain the load between the rubbing surfaces.
