Abstract
Abstract A removable handguide for painters or draftsman, adapted to be secured on an easel, and comprising a frame constituted by an upper crosspiece, a lower crosspiece, and two uprights, and at least one horizontal bearing bar slidably mounted on the uprights. At least the upper and lower crosspieces are each comprised by two separate half crosspieces, and a sliding member slidably mounted on the half crosspieces allows the adjustment of at least the width of the frame to the dimensions of a panel to be painted. The horizontal bearing bar has two legs each of which is provided at its free end with locking structure for locking the bearing bar along the uprights and each of which legs is secured by hinges to a sliding member slidably mounted on the uprights. The locking structure is preferably comprised by ferrules made of a material which is highly resistant to sliding, thereby preventing sliding of the bearing bar along the uprights when the bearing bar is in service position.
