    摘要： A space saving, door-mountable artist's easel with a framework adapted to receive and hold an artist's canvas, art panel, clipboard, or some other item that would normally be affixed to an easel with a mounting bracket attached to the frame so the entire device may be hung on a door. The easel can be used while mounted to the door it is stored on. In one example, a front pivoting frame enables the mounted piece to be extended outward from a back stationary frame. A height adjustment mechanism allows the mounted piece to be raised or lowered to a desired position, enabling the artist to stand or sit. The compactness of the easel enables an art piece being worked on to be left mounted to the easel for drying or viewing, and the door can still be opened and closed normally with the easel mounted to it.

    摘要： A supporting arm for a projection apparatus has first and second arm sections and an articulation apparatus therebetween for interconnecting the arm sections. The projection apparatus can be fastened on a free end of the second arm section. The articulation apparatus permits the second arm section to rotate relative to the first arm section between a first position, in which the longitudinal axes of the arm sections run substantially mutually parallel, and a second position, in which the longitudinal axes of the arm sections run substantially mutually at right angles. A spring apparatus is coupled to the arm sections and has a spring force selected to compensate for a weight force of the second arm section and of the projection apparatus fastened thereon over substantially an entire rotational excursion of the second arm section relative to the first arm section. A presentation apparatus having the supporting arm is also provided.
