The drawing board and the rest of this device do not yet offer the desirable simplicity.

Corresponding to the circle of people who predominantly use drawing boards, old simple rails , ₉ a susät looking for gatekeeping on such a drawing device should be so "cheap" that every student can purchase -d & esssik & e ^ * «ad ~ ä4e- £ & agaB & efe & gag should be as easy as possible and Tom Eeiitaett quickly abeixij, so that it is not difficult to transport the drawing board, for example between home and school. ■

The gate direction according to the present invention fulfills all these requirements to the greatest possible extent, because it _{can be 'put together from' the simplest possible 9} lightweight and very suitable punching and stitching parts for cheap mass production.
