Claim 1
Independent Claim
202 words
A writing support intended to be removably fixed on a wall, comprising: a profiled fixing strip, having a flat base for applying and fixing same by securing means to said wall, and comprising a longitudinal rib with dovetail cross-section for receiving and retaining an intermediate shaped adjusting piece; a writing receptacle element having a base wall with a longitudinal rib with dovetail cross-section for fixing to an intermediate shaped adjusting piece; and an intermediate shaped adjusting piece having, on a first face, at least a first longitudinal first face groove with a dovetail cross-section complementary to the longitudinal rib of the profiled fixing strip for fixing same to the profiled fixing strip and comprising, on a second face, at least two longitudinal grooves, each having a dovetail cross-section complementary to the rib of the writing receptacle element for receiving and retaining the writing receptacle element, which two longitudinal second face grooves are offset angularly so as to permit the intermediate shaped adjusting piece to be fixed with respect to the profiled fixing strip and to the writing receptacle element in at least two separate orientations defining two relative slants of the writing receptacle element with respect to the flat fixing strip base.
