ABSTRACT:
Improved support for reclinable boards that consists of two arms articulated to each other, forming a folding square and presenting jamming and releasing systems, that has been structured for reliable practical positions. Simple and functional constitution that permits reclining the board in different positions. For achieving these, the support has two arms (1 and 2) joined to each other in which common point (3) joins a crosspiece (10) which through its other end joins the axis (8) where a leg compass is joined (4 and 5) through which ends (6 and 7) are joined to the indicated arms. The mentioned crosspiece is provided with a longitudinal slot (9) where the axis slides (8) selectively engaging a series of upper inlets (11) of the slot in order to maintain the board in different angular positions.
