Description:
FIELD OF INVENTION 
       [0001]    The present invention generally relates to structures formed by panels made of rigid or semi-rigid materials associated with frames for the construction of doors, sliding screens, windows, enclosures and the like. More particularly, it relates to novel connectors associated with new profiles whereby screens which are structurally strong, mountable, demountable, lightweight and adjustable by the user are used for the construction of doors, sliding screens, windows, enclosures and other similar structures. 
       BACKGROUND OF THE INVENTION 
       [0002]    It is well known that reinforced buildable profiles with different structures made of aluminum and other materials such as window and door profiles were cut square at their ends. They are assembled together by means of screws. They are housed in spaces with previously extruded profiles for the purpose of receiving, wherein the profiles that are assembled orthogonally touch each other. These profiles are frameworks that may also have internal subdivisions within which are placed mirrors, blinds, shades or translucent panels and used, as windows, sliding doors or enclosures. In the industry, there are different distinguished ways to fasten the panels. It is contemplated that the placement of more than one of them in the same frame, such as windows with double or triple glass and distinguished details are sealed to prevent the passage of water with gaskets made of soft materials such as rubber or plastic and to prevent the passage of dust, even at the periphery of the frame, as is the case of felts. Additionally, detailed functionalities are incorporated and adaptability for use in hardware facilitating the movement of these structures and desired functionalities to open, move, close and secure the position thereof. 
         [0003]    The known prior art describes constructions of various underlying screen for constructing sliding windows, screens and/or windows. For example, US Patent Publication 20020053164; US Patent Publication 20030205002; US Patent Publication 20050166494, US Patent Publication 20060059780; US Patent Publication 2007005148; US Patent Publication 20100005726; US Patent Publication 20100307077; U.S. Pat. No. 4,398,373; and US Patent D407,828, describe sliding door arrangements or enclosure functions which operate based on either complicated glides or require complex hardware and/or profiles that make them difficult to assemble or in need of professional tools for assembly. Moreover, such screens, enclosures or partitions of the prior art do not allow quick and convenient handling of various panels in a single unit, either on a door, window or enclosure to combine materials, colors and for textures. Moreover, they do not allow the practical assembly of screens that can be adapted to particular needs regarding dimensions or aesthetic appearance of the consumer liking. 
         [0004]    The partitions, panels or enclosures of the prior art and the structures that are assembled from it also presents problems in its construction, as is the case with heavy weight and is directly proportional to the strength of their structures. That is, if strong structures are desired, it is necessary to use metal profiles that yield strength, and on the other hand, stiffness. Furthermore, the use of structures made of metals is expensive. 
         [0005]    Another problem with the panels or enclosures of the prior art is that usually the profiles with which the frames are assembled together is a drudgery and the assembly of such structures is more problematic when using fasteners screw type, rivets, and the like. 
         [0006]    A further disadvantage of the panels or enclosures that are currently on the market, is that very few are destined to the concept of “do it yourself.” The manufacturers of the products that target this market segment, neglect details such as the completion or finish of the panel and do not allow to conceal or disguise the cuts of the profiles that could be defective when cut by inexperienced hands or by amateurs to the extent required by the user. 
         [0007]    The applicant, in accordance with the present invention has developed a novel set of profiles and connectors which outweigh the problems and disadvantages of the prior art. Moreover, they are combined to build practical screens which can be modular and which in turn result in constructions of the type such as doors, windows, screens, enclosures and other similar or equivalent elements which are lightweight, having structural strength and visually appealing finish. 
       SUMMARY OF THE INVENTION 
       [0008]    The present invention relates to a mountable, demountable, detachable, and sizable screen, in an especially preferred embodiment, is used as a door, comprising a frame constructed from hollow, extruded profiles and preferably made from polyvinyl chloride (PVC). Other materials may also be used, such as metals. For example, profiles that are aligned by means of connectors at each joint with one or more wood fiber boards, or other rigid materials such as glass, mirror, rigid plastic panel, foam or hollow, which are confined in said frame. 
         [0009]    In one embodiment of the screen of the invention, the hollow profiles having at least one longitudinal groove in the form of a simple“U” or modified form of angle and depth, on its outer wall, wherein said groove, once the frame assembly comprising at least four hollow profiles, faces inwards the assembled frame and said groove into which the edges of the rigid panel which is confined in the frame are inserted. 
         [0010]    In a further embodiment of the screen of the invention, the frames can be assembled with two longitudinal hollow profiles and at least two transverse hollow profiles which are different from the longitudinal. Optionally, it is possible to place a third transverse profile, equal to or different from the other transverse hollow profiles attached to both longitudinal profiles at an intermediate position between both hollow transversal profiles and parallel to said profiles both constituting the outer frame transversal sections. They can be attached at any distance that is intended by dividing the outer frame so that two rigid panels instead of one may be placed inside the frame and these divisions can keep repeating and adding more hollow transversal profiles. When there is an intermediate transverse hollow profile, like the case of a third or subsequent profile, said profile has a “U” shaped groove along at least two opposite longitudinal lines on its outer side, so that it can receive the edges of the rigid panels to be introduced on both sides. 
         [0011]    In a further embodiment of the partition, enclosure, divider or panel of the invention, the hollow profiles are both longitudinal and transversal which allow insertion along their longitudinal axes structural filling elements that improve its resistance to bending, such as steel pipes, wood, other similar materials, or combination thereof. 
         [0012]    In a further embodiment of the partition, enclosure, divider or panel of the invention, the hollow profiles are both longitudinal and transversal. Said profiles also allow the introduction of filler strips of wood or other similar material so that the screw fittings on the exterior surface of the hollow profiles and the threads of the bolts are resistant to substrates to be anchored inside. 
         [0013]    In a further embodiment of the partition, enclosure, divider or panel of the invention, all of the referred profiles are perpendicularly cut to its longitudinal axis when assembled. 
         [0014]    In a further embodiment of the partition, enclosure or panel of the invention, the longitudinal profiles allow the passage of screws transverse to its longitudinal axis. 
         [0015]    In a further embodiment of the partition, enclosure, divider or panel of the invention, two or more transverse hollow profiles featured as a design profile, which receive the threads of the bolts in the direction of its longitudinal axis, are provided with at least a means for receiving said threads, is extruded to manufacture the profile, which is visible at both ends of the transverse hollow profiles. 
         [0016]    In a further embodiment of the partition, enclosure, divider or panel of the invention, each screw connection between the two hollow profiles, one longitudinal and one transversal, there is a connector that prevents direct contact between both hollow profiles, as a gasket interposed therebetween. 
         [0017]    In a further embodiment of the partition, enclosure, divider or panel of the invention, wherein the surface, within which each connector acts as a gasket, protrusions are projected longitudinally penetrating the ends of the transverse hollow profiles, in order to align the connector with the internal form of the transverse profile and ensure that no transversal deformation of the hollow profile occurs at the time of being assembled. 
         [0018]    In a further embodiment of the partition, enclosure, divider or panel of the invention, wherein the surface, within which each connector acts as a gasket, a gasket contour wall protrudes covering the first few millimeters of length around the end of a transverse hollow profile, making said end not to be seen. This prevents cutting defects in one or both ends of the transverse hollow profiles to be shown, defects resulting from an inexperienced application or suboptimal tools. Despite described circumstances, said protruding contour wall ensures optimal partition, enclosure, divider or panel appearance. 
         [0019]    In a further embodiment of the partition, enclosure, divider or panel of the invention, the connectors of the invention comprise projections which project perpendicularly from its gasket surface in a direction opposite to what has been described above, diverting away from the cutting surface of the hollow profile, so that, when connectors are positioned at the ends of a transverse hollow profile, said projections are external protuberances that engage and align with the groove in the shape of a continuous longitudinal “U” hollow longitudinal profiles show and are integrated for receiving rigid panels. 
         [0020]    In a further embodiment of the partition, enclosure, divider or panel of the invention, the gasket surfaces of the connectors, which act as joints between the longitudinal and transverse hollow profiles having perforations through which the screw passes or wherein the profiles are assembled and presented. These same surfaces show through grooves to allow the passage of assembled panel edges through the connectors&#39; gasket surface, letting simply square cut panels be framed inside longitudinal and transverse hollow assembly profiles without having to make any further operation on the panels prior to assembly. 
         [0021]    In a further embodiment of the partition, enclosure, divider or panel of the invention, it also comprises an additional rib or profile which, have a smaller section than the longitudinal and transversal hollow profiles and having a groove in a “U” on both sides. The grooves which are inserted on the edges of the rigid panels which, when linked by each such rib, before being confined in the space defined by longitudinal and transversal hollow profiles assembly, it is possible that the two panels joined by said rib only occupy a space defined by the hollow assembly, may be of different materials or finish. 
         [0022]    In a further embodiment of the partition, enclosure, divider or panel of the invention, the partition assembly allows the introduction of a guide element or protrusion profile that follows the longitudinal axis of a hollow transverse profile allowing to align the movement of the assembled partition, enclosure, divider or panel along a rail, a floor rail for example, said protrusion profile is simply attached to said hollow transverse profile by inserting it along the latter inside the form it is provided with to receive it. 
         [0023]    Therefore, an object of the present invention is to provide a novel set of hollow profiles and connecting elements, specially designed particularly to combine and thus assemble frames for manufacturing partitions, enclosures, dividers or panels of the type used for the assembly of doors, windows, screens, enclosures and other similar constructions. 
         [0024]    A further object of the invention is to provide a set of movable, mountable, demountable, separable or buildable elements of hollow and rigid panels that users can cut to the size at their own convenience for assembling panels, screens, dividers or partitions that can be used as enclosures, sliding doors and/or collapsibles for closet, for example, which are lightweight, economical and easily adaptable to the size of the space available at the time of placement, as well as, to ensure longer life of conventional hardware used for placement due to its low weight. 
         [0025]    A further object of the invention to provide a movable, buildable, mountable, demountable or separable partition, enclosure, divider or panel, having only one panel thickness of view, instead of two as is the case of a hollow core sliding door closet. The profiles become more competitive due to its lighter weight, prolonged useful life and lower manufacturing cost. 
         [0026]    Another object of the invention to provide a movable, buildable, mountable, demountable, separable or collapsible system component assembly of screens, which are handled separately as parts and/or modular packages with a variety of finishes and materials to manufacture enclosures, sliding doors and/or folding structures, likely to suit a variety of tastes and preferences to the consumer. 
         [0027]    Yet another object of the invention is to provide movable, buildable, mountable, demountable, separable or collapsible partitions, dividers, panels or screens and comprised of parts, which are packed in convenient sizes for transport and handling in accordance with commercial formats and supply chain for easy transportation of the same by the users with their own vehicles without using cargo transport. 
         [0028]    One more object of the invention is to provide components of a system construction of panels, partitions, dividers or screens, which are individually packaged so as to avoid damage or deterioration during transportation to the place of installation, where they are unpacked, assembled and built. 
         [0029]    Another object of the invention is to provide a construction system of panels, screens, enclosures, sliding doors and/or folding, wherein the components are easy to handle and introduced at any room in which to adapt, assemble and install the system in a manner which is more practical, easier, faster and less expensive as compared with traditional systems comprising conventional hollow core doors. The traditional systems which are employed for regular closet doors or enclosures are wider than the door openings between rooms and the size of the structure results frequently in an impediment in carrying them. For example, for a bedroom, a user may need the enclosures, screens, panels or partition where there are staircases and other spaces which do not fit or difficulty exists associated with the risk of damaging the walls to perform maneuvers, or there is a risk of damage to the finish of the walls. Sometimes, the only way to enter the chamber is to manipulate the assembly through a window with a risk of accident. 
         [0030]    Another object of the invention is to provide a building system that is movable, buildable or adaptable in a variety of sizes using rigid panels cut and obtained from original commercial sizes leaving zero waste using, for example wood 4′×8′ fiber sheets, thus reducing cost. 
         [0031]    Still another object of the invention is to provide bulkhead, partitions, panels or screens in which components comprise attractive finish, flexible and customized by the user. For example, extruded profiles may carry metallic, printed or colored and panels may be opaque in multiplicity of finishing, or may be transparent (glass), reflective (mirror) or translucent and may carry finishes applied by the user as for example, stretching fabrics over the panels before confining them in the frames. 
         [0032]    Still another object of the invention to provide bulkhead, partitions, panels or screens that can be assembled by the user by combining the color and texture characteristics of the panels according to their preference and decoration, combining different panels on a single project or jointing different panel materials within a single assembled frame using the above-described rib as the joint. 
         [0033]    A further object of the present invention is to provide panels, screens, dividers or partitions which are assembled by means of connectors which ensure no deformation of the profiles when constructed. Their construction permits use for thin walled extrusions or relatively soft materials such as PVC. 
         [0034]    These and other objects, advantages and features of the invention will result clearer from the detailed description of some preferred embodiments of the invention presented below, taken in conjunction with the accompanying drawings and claims.

     DETAILED DESCRIPTION OF INVENTION 
       [0052]    In the description that follows, it should be understood that when referring to “one partition” can mean either a segment or a plurality of segments formed by the longitudinal profiles (A) and transversal profiles (B) and Panels (C) illustrated in  FIGS. 1 and 1A , or the complete set formed by said segments. 
         [0053]    The following describes preferred embodiments of the invention and according to the drawings of  FIGS. 1 ,  1 A,  2 ,  2 A,  2 B,  2 C,  3 ,  3 A,  3 B,  3 C,  3 D,  4 ,  4 A,  5 ,  6 , and  7 , with the sole purpose of illustrating it better, but certainly it should be understood that this is not limiting the scope of the same. 
         [0054]    In an especially preferred embodiment, the invention provides a divider, partition, panel or screen comprising a perimetric frame formed by two longitudinal profiles A,  FIGS. 1 and 1A , preferably, both hollow as PVC extrudates, fastened with fasteners of the type of screws, rivets, and/or glued or toothed bolts G,  FIG. 1A  to two transverse profiles B,  FIGS. 1 and 1A , also preferably, hollow such as PVC extrudates. The framework which is confined within a rigid panel C,  FIGS. 1 and 1A , simply cut square, which may be of wood fiber or other rigid material, preferably glass, mirror, rigid plastic panel, hollow or foamed. While said panel remains confined within the frame, under which two of its opposite edges are inserted in the grooves  6 ,  FIGS. 2 ,  2 A,  2 B and  2 C, when joined to longitudinal profiles A,  FIGS. 1 and 1A , panels wherein two remaining opposite edges are inserted in the remaining transverse profile grooves  13 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, as said edges are attached to the transverse profiles B,  FIGS. 1 and 1A . The transverse profiles can be more than two with the frame that forms the perimeter by virtue of which it is possible to connect a larger number of transverse profiles B,  FIGS. 1 and 1A , at both longitudinal profiles A,  FIGS. 1 and 1A , at preferred positions. Then, dividing the interior space of the frame in more than one segment to confine the space or rigid panels C,  FIGS. 1 and 1A . The transverse profiles B,  FIGS. 1 and 1A , which are joined to the longitudinal profiles A,  FIGS. 1 and 1A , without the two elements touching each other because they are sandwiched between connector D,  FIGS. 1 ,  1 A,  5  and  6  which can be left or right as needed and which has the function of ensuring proper alignment between said assembled profiles A and B,  FIGS. 1 and 1A . This is performed to prevent possible deformation of the transverse profiles B,  FIGS. 1 and 1A , when assembling and to cover presumably poor cutting finishing at on one or both ends of the transverse profiles B,  FIGS. 1 and 1A , when they are cut by the user before assembly, covering provided in order to obtain a partition to the desired size and neat appearance.

So that by using one of these rib profiles E,  FIGS. 1 and 1A , it becomes possible that in a single aperture formed by the assembly of profiles A and B,  FIGS. 1 and 1A , it is possible to introduce more than one panel section C,  FIGS. 1 and 1A , in such a way that there are two or more vent panels C,  FIGS. 1 and 1A , joined at their edges. There is then the advantage that the sections of panel C,  FIGS. 1 and 1A , can be designed based on the desired dimensions of the screen object of the invention. While it is possible to use sections of panels C,  FIGS. 1 and 1A , which are of multiple size or to utilize more convenient size without wasting commercial size panels for manufacturing the object screens of this invention, it is also achieved, by incorporating the rib profile E,  FIGS. 1 and 1A . Thus, the possibility of changing the material, for example, of rigid panel of wood fiber side of the rib profile E,  FIGS. 1 and 1A , a glass or plastic translucent material across the rib profile E,  FIGS. 1 and 1A , resulting in increased functionality of the enclosure object of the invention.

Given that it is the rear side  4 ,  FIGS. 2 ,  2 A,  2 B and  2 C, this being the side suitable to incorporate more functionality detail as one or more longitudinal protrusions  7 ,  FIGS. 2 and 2A , which project into longitudinal profile section,  FIGS. 1 ,  1 A,  2  and  2 A allows obtaining an optimum dimension within the longitudinal profile,  FIGS. 1 ,  1 A,  2  and  2 A, to insert structural reinforcement elements  8 ,  FIG. 2A , which are of commercial size. The provision of longitudinal protrusions  7 ,  FIGS. 2 and 2A , on the rear side  4 ,  FIGS. 2 and 2A , the longitudinal profile A,  FIGS. 1 and 1A , due to the existence of the protrusions tends to create finishing defects along the outer surface of the extrusion when it is plastic, on the opposite side of the wall may allow potential defects. 
         [0061]    In a preferred embodiment of the invention, the cross section B,  FIGS. 1 ,  1 A,  3 ,  3 A,  3 B,  3 C and  3 D, is preferably, a hollow profile such as PVC extrudate, which is capable of receiving therein reinforcement inserts  16 ,  FIGS. 3A and 17 ,  FIG. 3B , which improves its mechanical capabilities. Inserts may be of a variety of materials and profile B,  FIGS. 1 ,  1 A,  3 ,  3 A,  3 B,  3 C and  3 D outer surface may be finished in solid color, translucent or transparent, metallic or pearly appearance, according to the formulation of the extruded compound or may allow laminated coverings or transferred finishing on its outer wall that may even be printed, textured, or both. 
         [0062]    In this embodiment, each transverse profile B is characterized by four sides, namely: side  9 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, which is its side view, the side coinciding with the main view of the panels C,  FIGS. 1 and 1A . This is therefore part of the main view screen object of this invention and can have different shapes at will, form and/or taste by the designer, in order to achieve better acceptance of the partition by the user. There is a possibility that the side  9 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, is flat or has grooves, broken or curved shapes that highlight their pleasing appearance to the user. 
         [0063]    Sides  10  and  11 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, which sides correspond to the transverse profiles B,  FIGS. 1 and 1A , presented to the interior of the frames formed with the longitudinal profiles A,  FIGS. 1 and 1A  and transverse B,  FIGS. 1 and 1A . The sides can be of any shape provided they have integrated a groove  13 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, always necessary in any of the sides  10  and  11 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, since in these grooves  13  work as housing for the edges of the panels C,  FIGS. 1 and 1A , which are confined in each frame formed by the profiles A and B,  FIGS. 1 and 1A . These grooves  13 ,  FIGS. 3 ,  3 A, and  3 B, are not closed at the bottom because this is used to continue with further extensions  14 ,  FIGS. 3 ,  3 A, and  3 B, and ending with sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B. This is designed to receive, when moving axially, the spiral threads of the clamping elements or screws G of  FIG. 1A , that ensure the assembly of the various elements of the enclosure object of the invention. The structures formed by the elements  13 ,  14  and  15 ,  FIGS. 3 ,  3 A, and  3 B, to be joined or defining a continuous path, allowing the post-formed tooling extruded profile, reaches the interior of the sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B, guaranteeing its shape and position and then facilitating the assembly of the ends of the transverse profiles B,  FIGS. 1 and 1A , when adjoining connectors D,  FIGS. 1 ,  1 A,  5  and  6  which can be fitted into said ends. According to a preferred embodiment, said connector elements are manufactured with a casting mold, therefore with greater precision than plastics profile extrusion tools, then the structures formed by the elements  13 ,  14  and  15 ,  FIGS. 3 ,  3 A, and  3 B allowing better controlled dimensions and positions for sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B, in comparison to the wider range of variability in dimension and position of the sleeve receptor  15 ,  FIG. 3C , that does not have the above structure and arrangement of the elements  13 ,  14  and  15 ,  FIGS. 3 ,  3 A and  3 B, sleeve receptor  15 ,  FIG. 3C , left at a point in which no tooling can achieve its post-forming, then eliminating the possibility of fine control of its shape, size and position. 
         [0064]    In  FIGS. 3 ,  3 A,  3 B and  3 D, the prolonged groove is formed by the elements  13 ,  14  and  15 ,  FIGS. 3 ,  3 A, and  3 B, and as already mentioned, also enable the axial insertion of the guide profiles F,  FIGS. 1 ,  1 A, and  7 , which are supported directly from sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B. As shown in the drawing of the guide profile section F,  FIG. 1A , which section is detailed in  FIG. 7 , it exists in a thickened wall  35 ,  FIG. 7 , designed to be inserted axially into the sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B, so that the guide profile F,  FIG. 1A  and  FIG. 7 , be engaged to the structure formed by the elements  13 ,  14  and  15 ,  FIGS. 3 ,  3 A, and  3 B, which is either on side  10 ,  FIGS. 3 ,  3 A, and  3 B, or side  11 ,  FIGS. 3 ,  3 A, and  3 B, on one of the transverse profiles B,  FIG. 1 , assembled perpendicularly to the ends of the profiles A,  FIG. 1 , so that the extension  37 ,  FIG. 7 , the guide profile F,  FIGS. 1 ,  1 A and  7 , extends beyond the boundary of the transverse profiles of said full B,  FIG. 1 . Therefore, the aforementioned extensions  37 ,  FIG. 7 , protrude beyond the total length of the longitudinal profiles A,  FIG. 1 , where the guide profiles F,  FIGS. 1 ,  1 A and  7  are placed. These extensions allow the outgoing bulkhead object of the invention to be guided in parallel rails (not shown) to the transverse profiles B,  FIG. 1 , which is movable. The said guide profile F,  FIGS. 1 ,  1 A,  7 , can not move and dislodge through the tip of the profile B,  FIGS. 1 and 1A , by virtue of its limited axial movement by the existence of the clamping elements G,  FIG. 1A , which prevent the passage. 
         [0065]    Finally, side  12 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, which is the rear side of the bulkhead transverse profile B of the invention and which is the side having said transverse profile towards the side opposite the main view. The side which may be of any shape depending on the shape of the transverse profile,  FIGS. 1 and 1A , being said side most suitable for allowing more unattractive elements derived from the manufacturing process. 
         [0066]    According to embodiments of the invention, the rigid panels C,  FIGS. 1 and 1A , are panels that other materials may be made from wood fiber, cardboard, chipboard, plywood, glass, mirror, solid plastic, foam plastic, or mixed wood and plastic compound. Depending on the material they are made of, they are able to receive finishing by painting, printing, or texturing and are characterized because, to be assembled with the other elements of the screen object of the invention, they require no further machining, recesses or anything but cutting their size to square angles, which can be practiced with rudimentary tools or even by non-specialists or unskilled personnel such as a home user, to size the dimensioned panels C,  FIGS. 1 and 1A , according to the individual dimensions of the space required in place. Some cuts may end up hidden in grooves  6 ,  FIGS. 2 ,  2 A,  2 B and  2 C of the longitudinal profiles A,  FIGS. 1 ,  1 A,  2 ,  2 A,  2 B and  2 C. Other cuts may remain hidden in grooves  13 ,  FIGS. 3 ,  3 A,  3 B, and  3 D of the transverse profiles B,  FIGS. 11A ,  3 ,  3 A,  3 B,  3 C and  3 D, or are hidden in grooves  21 ,  FIG. 4 , of the outlines rib E,  FIGS. 1 and 1A  integrated to the bulkhead of the invention. All mentioned grooves have a width suitable for the thickness of the panel C,  FIGS. 1 and 1A , used to build a screen according to the invention and according to the function it may be given, depending on the dimensions required, and finish and use, a user intends to give. 
         [0067]    According to an especially preferred embodiment of the invention, the connectors D,  FIGS. 1 ,  1 A,  5  and  6  are preferably pieces produced by injection in casting molds which may be of plastic or metal or other similar material, or can be obtained by stamping so that one can get different finish, colors and textures. These connections D may be left or right to be placed at the ends of the transverse profiles B,  FIGS. 1 and 1A . It depends on whether the form of such transverse profiles B demands. These connectors D which are interspersed in each assembly is assembled between longitudinal profiles and transverse profiles B, causing both mentioned profiles not touching each other directly. 
         [0068]    In a preferred embodiment, each of the connectors D is characterized by being composed of the following elements or components, with particular reference to  FIG. 5  of the accompanying drawings: A seat gasket  25  which is flat on the inside D. Connector Flat surface which rests against the square cut from each end of a cross profile B, and within which penetrate the structures  28 ,  31  and  32 . 
         [0069]    Each of the two structures  28  is a rigid shell seat which surrounds at least part of the perimeter of the sleeve receptor  15 ,  FIGS. 3 ,  3 A and  3 B, which are exposed at both ends of the profiles B, so as to embrace, the said sleeve receptor  15  and can not move from its place by the stresses to which they are subjected when a clamping element or screw G,  FIG. 1A , makes its way and anchors its spiral thread in said sleeve receptor  15 . The fixed position of the sleeve receptor  15  is guaranteed for receiving the aforementioned process even though the material from which it is made said profile portion B which are relatively soft, such as structures  28  hold down sleeve receptor  15  which are attached, due to the existence of a taper  29  that permits the structures  28  progressively hold down the outer walls of the sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B, the connector D to infiltrate, at each end of the transverse profiles B. The previous description is the reason that the connectors D help maintain the rigidity of the armed assemblies between the longitudinal profiles and the transverse profiles A and B, although the latter may be made of a relatively soft material such as PVC. 
         [0070]    Continuing with reference to  FIG. 5 , on the inner side of the connector D is located the wall  32 , which protrudes perpendicularly to the inner surface of the wall, seat gasket  25  which connects the two enclosures  28  to unite and increase the rigidity of the relative position between the latter, thereby improving the mechanical behavior of resistance to deformation of the connection between each connector D and end of B in the cross section profile that it penetrates. There are also two holes  30  which can be viewed both by the inside of the connector D, as for the outside of the connector. As shown in  FIG. 6 , the holes have the purpose of permitting the passage of clamping elements G which penetrate the gasket so as to join the longitudinal profiles and the transverse profiles A B, passing freely through the holes  30 . 
         [0071]    Adjacent to orifices or holes  30 , and the flat inner side of the gasket  25 , there is at least one projection  31 ,  FIGS. 5 and 6 , which grows in parallel to the structures  28  and projections  31  are such that one of their sides is the axial extension of the internal perimeter of each of the two holes  30 , while the rest of the body of the projections is inserted into the extensions  14 ,  FIGS. 3 ,  3 A and  3 B of the ends of the B profiles when inserting D connectors into said ends. The result is that the space for the passage of the clamping elements G, has a limit or stop that prevents said clamping element G to deviate from its desired path when being assembled to the interior walls of sleeve receptor  15 ,  FIGS. 3 ,  3 A and  3 B since such projections  31 , embedded in the extensions  14 ,  FIGS. 3 ,  3 A and  3 B, prevent any deviation occurrence. 
         [0072]    Continuing with reference to  FIG. 5 , around at least a part of the contour of the flat side of the seal  25  rises perpendicularly to said gasket, a wall  27  which, following the shape of said part of the contour has, by its inner side, a shape that matches a decided shape to match at least with the shape of side  9 ,  FIGS. 3 ,  3 A,  3 B,  3 C,  3 D on B transverse profiles. The wall  27  is intended to cover the outline of said transverse profile B when the connector D is inserted at its end, so that said wall  27  covers or conceals the end of said transverse profile B, preventing the user to see the quality and perfection or imperfection of the cut made to the cited profile B, prior to the assembly. Cutting is performed by the user in order to adapt the size of the enclosure object of the invention in accordance with the user needs. The wall  27  can also wrap the transverse profile contour of said at least part B of the sides  10 ,  11  or both, shown in  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D, in order to cover the cut made by the user when dimensioning the length of said profile B. The provision of the wall  27  corresponds to hide said cutting when the user views the screen of the invention in its normal position of use. In this described embodiment, connector D corresponding to hide the cut sides  9  and  10   FIGS. 3 ,  3 A, and  3 B, which are curved when they meet one another. In such an embodiment, it is necessary to assemble a connector D that is, by its right orientation, placed at one end of the transverse profile and a left orientation connector D is needed to perform the same function on the opposite side of said profile. The situation would be different, i.e, need not have left and right orientation for the connector D, in the case of a wall  27  of a connector whose object D is to cover the outline of sides  9 ,  10  and  11  of a profile B as illustrated in  FIG. 3C . 
         [0073]    As illustrated in  FIGS. 5 and 6 , the connector D also includes two openings or recesses  26  that traverse the entire thickness of the gasket  25 . Openings are axially aligned with the slots  13 ,  FIGS. 3 ,  3 A,  3 B,  3 C and  3 D of profiles B, when the connectors D are assembled at their ends. The said openings or notches  26  allow the length of the edges of the panels C assembled in said slots  13  to cross gasket  25 , as said lengths are greater than the length of the transverse profiles B, then allowing said panels C protrude from both ends of said profile B. The excess length of such panels C, distributed on both sides of the transverse profile B, can penetrate into the longitudinal profiles grooves  6 ,  FIGS. 2 ,  2 A,  2 B and  2 C, finally being confined in frames formed by the profiles A and B,  FIG. 1 , without need to do more than square cut operations of said panels C, before assembly. 
         [0074]    As illustrated in  FIGS. 5 and 6 , the connectors D comprise at least two guide pins  34  projecting from the outside of said connector D. Said guide pins may be two or more and which are intended to penetrate and smoothly set in longitudinal profiles of A slots  6 ,  FIGS. 2 ,  2 A,  2 B and  2 C, so that the connectors D,  FIGS. 1 ,  1 A,  5  and  6  may not rotate in a plane perpendicular to the axes of the guide pins  34 , when inserted into said slots  6 . The movement is also preventable if instead of providing two or more guide pins, a single continuous body is incorporated to unite both guide pins  34  further comprising that the surface of the gasket  25  on the outer side of the connector D as illustrated in  FIG. 6  may not be flat as it will have to match the shape of the longitudinal profiles A, side  3 ,  FIGS. 2 ,  2 A,  2 B and  2 C, when assembled to form the bulkhead of the invention and the shape of said surface depends on the shape of said side. 
         [0075]    As illustrated in  FIGS. 5 and 6 , there is a groove  33  in the connector wall  27 . Said groove is technically not essential but has an aesthetic purpose for the said wall  27  to mold to the external contour of the hollow profile section B, as illustrated in  FIGS. 3 ,  3 A and  3 B. As seen in these figures, there is a groove shape more or less at the middle of side  9 ,  FIGS. 3 ,  3 A and  3 B which is adjusted against the aforesaid wall  27 ,  FIGS. 5 and 6 . 
         [0076]    According to one embodiment of the invention, the rib profile E,  FIGS. 1 ,  1 A,  4  and  4 A, is a hollow profile and preferably PVC extrudate or aluminum, in order to be more rigid. Its outer surface may be finished in solid color, translucent or transparent, metallic or pearly appearance, according to the formulation of the extruded compound or may admit laminated coverings or transferred finishing on its outer wall that may be even printed, texturized or both. The rib profile is characterized by having two sides  19  and  20 ,  FIGS. 4 and 4A , any of which may be left to the user&#39;s view, in accordance with the preference of the same user, because one will be in view for the side view of the principal side of the joined C panels,  FIG. 4A , and the other may be seen by the after-side of said panels together. 
         [0077]    In this embodiment being described with reference to  FIGS. 4 and 4A , the rib profile E is characterized by comprising the following elements: two grooves  21 , at opposite positions, to allow insertion of the edges of panels C, in opposite positions, so that by using one of these profiles, rib E becomes possible that in a single aperture formed by the assembly of profiles A and B, it is possible to introduce more than one panel section C,  FIG. 1A . In this opening, there are two or more panels C,  FIGS. 1 and 1A , attached by its edges. The advantage that the panel sections C can be designed based on the desired dimensions of the screen object of this invention, while it is possible to use panel sections C which are of multiple size or convenient size to utilize waste without commercial size panels for the manufacture of the partitions object of the invention. The possibility of material change is further achieved by the incorporation of the rib profile E. For example, a rigid panel of wood fiber side of the profile rib and a translucent glass or plastic profile across the rib profile E, resulting in the increased functionality of the enclosure object of this invention. 
         [0078]    As shown in  FIGS. 4 and 4A , the rib profile E includes a tubular section  20  of a desired shape. The tubular section with which it is achieved that the rib profile E can provide greater resistance to bending when pushed by forces perpendicular to the side or side-view behind panels C, preferably tubular section is to save material in the manufacture of E rib profile. The said rib profile includes two gripping mechanisms arranged on the side panels of the axis of symmetry of rib profile E. Each of these mechanisms comprises a spring  22  and a safe  23 , components that facilitate and ensure firm assembly and to secure panels C,  FIGS. 1 ,  1 A and  4 A, under which, when measuring parallel to the axis of symmetry of rib profile E, the springs  22  are closer to tubular section  24  than the thickness of panels C. Said fact forces the aforementioned springs, deforming in parallel to said axis of symmetry when said panels C are inserted as shown in  FIG. 4A . When panels C are inserted, there is a force exerted by the material from which is constructed the rib profile E. The strength of pressing the panels C against the tubular section  24 , and said force creates a torque on panel C, when fitted on one side of the profile E according to  FIG. 4A , under which, the reaction force or strength of pressing offered by the tubular section  24  is not aligned with the point of application of the force exerted by the spring  22 . When reaching the bottom of the groove  21 , said torque cannot rotate the panel C in relation to the rib profile E, under which said panel C is subjected, because there is a safe  23 . Safe  23  certainly provides a reaction force that cancels the aforementioned torque.  FIG. 4A  shows that the opening between the spring  22  and the tubular section  24  is larger than the thickness of panel C inserted between the said elements, said opening facilitating insertion of panel C between said two structures. In addition, it is appreciated that in order to facilitate panel C edge to reach groove  21  bottom, and accommodate the insertion between the tubular section  24  and the safe  23 , the said safe is arranged so that the distance between it and the said tubular section, is decreasing and approaches the thickness of panel C as it approaches the bottom of the groove  21 . 
         [0079]    In one embodiment of the invention, the partition object of this invention further comprises one or more guide rails F,  FIGS. 1 ,  1 A, and  7 , which is optional for the user to add or disregard on the top or bottom of the screen object of the invention. These guiding profiles are preferably PVC extrudates and engage the transverse hollow profiles B,  FIGS. 1 ,  1 A,  3 ,  3 A and  3 B, which are placed at the ends of the longitudinal profiles A,  FIGS. 1 and 1A . When such assemblies are built, the top and bottom ends of the screen object of the invention exhibit projections which can slide transversely on rails (not shown) both above and below. In the preferred embodiment of the invention, an option for the screen object of the invention which can be operated as a sliding door, wherein said guide rails F are supported directly by the sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 , due to the thickened wall  35 , intended to be introduced axially into the sleeve receptor  15 ,  FIGS. 3 ,  3 A, and  3 B, so that the guide profile F remains engaged to the structure formed by the elements  13 ,  14  and  15 ,  FIGS. 3 ,  3 A, and  3 B. This is located either on the side  10 ,  FIGS. 3 ,  3 A, and  3 B, or in side  11 ,  FIGS. 3 ,  3 A, and  3 B, on one of the cross section B, which are assembled perpendicularly to the ends of profiles A, so that the prolongation or extension  37  of said guide rail profile F extends beyond the boundary of the perimeter of the said section or full cross section B. Therefore, the said extensions  37  protrude beyond the overall length of the longitudinal profiles A when the guide rails F are positioned. The projecting extensions which allow the partition of the invention can be guided in parallel rails (not shown) to the transverse profiles B in which the said partition is moved. Said guide section F can not be shifted and dislodged through the tip of the profile B because its axial movement is limited by the existence of the clamping element G which prevent the passage. The extension  37 , is connected to the bulge  35  by means of a link  36  which may or may not be required or may have a different shape, depending on the configuration having the structure of the components  13 ,  14  and  15 ,  FIGS. 3 ,  3 A, and  3 B, incorporated into the transverse profile B. The guide profile F also comprises two projections  38 ,  FIG. 7 , away from the axis of symmetry of the extension  37  so that they can not be inserted between the two walls of the groove  13 ,  FIGS. 3 ,  3 A, and  3 B, and remain outside the outer circumference of the hollow profile section B. The thickness of said projections  38  projecting beyond the length of the longitudinal profile A when F profile is coupled to one of the hollow profiles which are positioned transversely to A. Thus, another object of the invention bulkhead is if placed standing on the profile F, previously assembled, and the extension  37  of that profile is housed in a groove that, for example, be in the floor or in a framework within which it is intended to move the partition of the invention like a sliding door or enclosure, and said groove is barely wider than the thickness of extension  37  as well as deeper than said extension protrusion length, then the two projections  38  rest on top of the sidewalls of said ground groove, separating the lower end of both the lower longitudinal hollow profiles from the said groove of the floor. Both projections  38  being constituted in bearings on which the sliding takes the place to form the enclosure object of the invention.
