New adjustable housing for the perimeter configuration, support and regulation of a sliding door or similar, especially for sliding doors of cabinets placed in furniture or built-in, which run between two upper and lower guides. With filming means arranged in a base plate screwed to the back of the door, or running through the closed perimeter and miter cut of the profiles that make up its perimeter recess where independent parts run, carriages carrying bearings driven by springs, towards the lower exterior of the door, held by independent pieces of interposition attached to the bases through which the bearing parts of the wheel slide. characterized by: the main bodies (1a) and (1b), concur in a vertex of rounded shape (3) integral with each other, by an adjustable pin (2) with ability to move gradually, both constitute a housing (5a) and ( 5b) located on the corners or vertices of the panel or door (25), the main body of the plates (1a) and (1b) protrude wings (4) of greater measure and different thickness, which are interrupted on its inner perimeter enabling its graduation, while forming the perimeter recess of the panel or door (25) with means to make both the vertical profile (6) that attends with straight cutting, with the (7) with the same configuration in the back of them open, to receive the wings (4) both of the casing (5a), supported by the fastening means (9) that are introduced in the threaded holes (8) located in the main bodies (1a) and ( 1b), pressing on the front face of the profiles (6) and (7) or crossing the same, which in turn incorporates in a dependent manner and into the structure (1b) of the casing (5a) a security system constituted by a piece (12) with horizontal partition (20) that limits its lower displacement and connects the panel or door (25) with the lower guide rail (18) by means of the internal legs (16) when they are introduced in the wheel arch (17), also incorporates a door speed regulator, constituted by extensions (33) in which is provided with a threaded hole (8) to be crossed by a screw (36) that when striking the part (35) carrying the cleaning brush presses the slit (37) of the bearing (23) limits the speed of the panel or door (25) in the horizontal path thereof between the upper (45) and lower (18) guides of the same configuration in the open rear part the profile (47) delimits the different parts of the panel or door (25) configuring a form of h once joined the parts of which are c ompone (47) and (52) in which the different pieces in which it is desired to divide or build is introduced, the profile (47) has an internal recess in the form of an inverted u (50) and a grated arrangement (51a) on the which receives the termination (52) in the form of t which has projections (51b) in contrast to those located in the recess (50) in the form of an inverted u (51a) adjustable according to thickness of the panel or door (25). The carcass (5b) that is placed in the vertices of the panel or door (25) and that is introduced in the profiles (6) that attends with straight cut, with the (7) with the same configuration in the back of the same open, to receive the wings (4) the upper (5b), supported by the fastening means (9) that are inserted in the threaded holes (8) located in the main bodies (1a) and (1b), pressing on the front face of the profiles (6) and (7) or passing through them, which in turn incorporates a horizontal partition (38) that extends in a dependent manner and in the structure (1b) of the housing (5b). Inverted l shape, with threaded holes (8) so that by means of fixing screws (9) they support one or more upper guiding systems, such as the one housed in one of the threaded holes (8), which is more close to the vertex of the housing (5b) and which consists of a bearing in horizontal position (39) supported by a screw (40) protrudes lining of the perimetric profile (7) and the extended horizontal partition (38) the bearing (39) has internal slit (42) where a gasket of malleable material (41) is housed next to and opposite to the apex of the casing (5b) ) describes two holes with threaded (8) misaligned with each other, to accommodate a part (53) carrying two or more bearings (43a) and (43b), the (43a) remains supported by the fastening screw (44) in a fixed and protruding position of the horizontal extension in the form of an inverted l, while the (43b) is located closer to the visible side of the panel or door (25) and protruding sufficiently from the perimeter profile (7) driven by elastic means (54), then and in the opposite direction to the apex of the housing (5b) a threaded hole (8) located in the horizontal extension in the form of an inverted l depending on the main body (1b) of the housing ( 5b) arranged to receive a threaded pin (46) (55) ) and that in its lower part has an elongated slit in the perimeter thereof (56) that protrudes through the lower face of the horizontal extension in the form of an inverted l with possibility of adjustment towards the outside of the upper edge of the panel or door (25). ).
