Abstract
Abstract An article, such as the cabinet of a record changer, is provided with a wall which faces outwardly and projecting outwardly from the wall is a ledge on which the lower rim of a dust cover rests. Cooperating elements of a hinge arrangement are formed on the lower edge of the rim and on the wall of the article so that the dust cover can be tilted upwardly to expose the top of the article. Cooperating elements of an abutment arrangement also stop the dust cover in a tilted position on the article so that it is supported with the top of the article exposed.
