  • Patent number: 6729057
    Abstract: A handy encasement for sign or advertisement board is essentially sustained with a couple of transverse skeletons and a couple of longitudinal skeletons. The transverse or longitudinal skeletons are equipped with a base and an upper lid combined together so as to encircle an accommodation space. A spring bow is intercalated between the base and the upper lid of the transverse skeletons such that the upper lid can keep a proper open angle with the base by its one side remains articulated with the base thereby facilitating replacement of inner components of the encasement. Jointing four mating portions between the bases and the upper lids with four corner junctions and patch members configurates a handy encasement without the need of any tools. A rectangular slot formed along inner edges of the encasement makes it possible to glaze a surface board on each surface for signs or advertisements.
