ABSTRACT:
An adjusting device includes a channel fixed to a rear surface of a frame. A slot is longitudinally formed in a rear surface of the channel. A guide is slidably received in the channel. A lug is formed on the guide and extends outward from the slot. A lug is formed on a hanger. The ends of a link are coupled to the lugs by screws and nuts so that the relative angles between the channel and the link and between the link and the hanger can be adjusted by the screws and nuts, and so that the frame can be easily adjusted to a suitable angle relative to a support surface.
