Some (classical) graded contractions of $so(2,2)$ associated to a $Z_2 \\times Z_2$ grading are studied, and the automorphisms defining this grading are generalized to the quantum case, thus providing quantum contractions of this algebra. This produces a new family of \"non-standard\" quantum algebras. Some of these algebras can be realized as (2+1) kinematical algebras; we explicitly introduce a new deformation of Poincar\\'e algebra, which is naturally linked to","authors_text":"A.
