Enclosure tilt, type comprising a fixed to a vertical profile rotatable relative to the facing sheet on which installed the screen and understands supports for rotation of said profile, a horizontal profile lower blade and for seals of set; characterized by the following items: --a fixed vertical profile general section uy provided at the free edge of each wing, an oblique aleta facing the inside, and reached curvoconcava a parallel nerve to wing and toward the audience interior, each ala a flap perpendicular, internal and intermediate and arranged between said two pairs of fins a seal magnética, rectangular section and provided with two nerves rounded, projections and placed in sendas corners of greater face of the board, which extends laterally along sendas stepped projections that fit between two pairs of fins cited; --a profile vertical rotating section piriform open with two interior walls cross, intermediate and aligned, the free ends are topped with paths fins perpendiculars and facing each other, so that both partition walls with their fins are arranged symmetrically to the plane longitudinal central profile, whose mouth presents inward two appendixes faced, parallel with respect to these walls and determining two small channels upright in staying sendas seals, projecting inwardly from starting said appendixes sendos tabiques longitudinal parallel to said longitudinal and aligned with flap for partition transverse plane, and this profile has, in addition, two more longitudinal partitions willing inwardly from the rounded part of the profile, aligned with flap septum cross for and with partitions projected from the appendix, c uyos two paths intermediate walls perpendiculars longitudinal fins presented, facing and aligned with each other and defining a space in which lies a magnetic strip. --two upright fixing the blade, one upper and lower, u-section, each having an expansion also in u at its outer end, which is located prismatic tuerca; --a regulating bottom cover, piriform outer contour corresponding profile with vertical revolving, at the lower end is engaged by two pairs of legs vertical, projected upwards from a circular base in whose side opposite - inferior-- tubular wall has a circular and between legs whose staying tightly expansion profile for securing the blade, legs that are inserted snugly into the respective cavity profile vertical revolving determined intermediate between each transverse partition, the outskirts of profile and related tabiques longitudinal, and this cover has two vertical fins prolongación part narrow your contour and symmetrically to the plane central longitudinal top as well as a channel deep transverse situated oppositely such skirts and between two minor openings swivels, and an appendix tubu lar projected central circular haci a down and concentric with wall tubularcircular; --a top cover regulation, piriform outer contour corresponding to the vertical profile rotating, but finished off by a front wall extends upwards and in a section c wings divergentes, and this cover is attached to the upper end of profile vertical revolving by two pairs of legs vertical, projected down from a circular base in whose face --superior-- opposite wall tubular has a circular and between legs whose staying tightly expansion vertical profile for securing leaf, legs that are inserted snugly into the respective cavity of the vertical profile giratorio, determined between each transverse partition intermediate, the outskirts of profile and related tabiques longitudinal and this top presents in addition a channel deep cross placed oppositely to said front wall and minors between two openings swivels, and an appendix central circular tubular p royectado up and concentric circular with wall tubular; --two supports for vertical profile of rotating tilting, through his two composite regulating tapas each one part tubular tubular equipped with an appendix each composed part tubular tubular equipped with an appendix concentric, in this entered the tubular appendix of the proper and respective cover for regulating and starts from a base of contour somewhat higher, which extends into a prismatic rectangular on thinness and equipped with two legs verticales projecting in the same direction chelates tubular part and that are adjusted within the fixed vertical profile being also provided with said prismatic part two holes traversed by two screws screwed into respective channels c-shaped, located inside the vertical base of quoted vertical profile fixed; and --a lower horizontal section profile h. Attached to the lower side of the blade cap and adjusting lower through its two fins, among which is set and whose profile has attached a seal inferiorly and butt free is closed by a lid vertical, horizontal equipped with an appendix for unión to aforementioned profile.
