ABSTRACT:
A portable drawing apparatus configured to act as an easel and/or desk includes a pair of upper support members each pivotally connected to a respective lower support member, and also each pivotally connected to a respective rear support member. In an operational configuration, the rear support members can project rearwardly in a plane substantially normal to a plane defined by two mutually parallel upper support members. A lower cross frame and upper cross frame are each connected to respective lower support members, and upper support members, and each further connected to the non-removable portion. A hinged lateral member, when configured in a locked position, defines the apparatus width. In a collapsed configuration, the distal portions of the upper and lower support members are configured to point in the same direction and form a bundle whose length is substantially less than that of the apparatus length in operational configuration.
