Description

Object of the Invention

The invention relates to two tubular metallic profiles, one round profile and another oval profile, and to an assembly of pre-assembled elements for constructing articulated fences and railings which can be directly assembled to one another on-site without needing welds, or special machining as a result of the fact that the particular geometry of the elements and the different mechanisms form an articulated modular system of firm and long-lasting mechanical attachments. The articulated elements allow the assembled assembly to adapt to all types of planes and outlines without needing workshop operations. The versatility of the system allows numerous different compositions and the incorporation of different materials such as boards, glass, cables, tubes and solid wood bars. The invention consists of two metallic tubular profiles and their specific machining in the factory, assembly and fixing parts, anchorings to walls and to floors, and the assembly of all the elements to one another.

Background of the Invention

There is currently no system designed with these specifications which is modular, articulated, able to incorporate different materials such as boards, glass, cables, tubes and solid wood bars, and with so many different configurations and on-site installation ease. For said purposes, reference is made to the following patents belonging to the same inventor, M. A. Bermejo, E 1 614 826 B1 of Trenzametal, S.A. for: REMOVABLE MODULAR URBAN RAILINGS; E 0004 380114/1 of Natural Faber, S.A. for: DEMOUNTABLE ARTICULATED TUBULAR STRUCTURE FOR RAILINGS AND THE JOINTING AND FIXING COMPONENTS THEREOF and E 0006 380207/ 8 of Natural Faber, S.A. for: ENSEMBLE ARTICULÉ DE BARRIÉRES DE PROTECTION. Inventive Step
As can be summarized from the disclosure referred to the object of the invention in the preliminary paragraphs of this specification, the advantageous purpose of such invention is to provide preassembled and prefabricated modular elements for the installation of (indoor and outdoor) fences, latticework, partitions and railings, with a great variety of configurations and incorporation of materials (boards, glass, cables, tubes and solid wood bars) according to the functional needs, the final on-site assembly of which is carried out without welds or workshop machining, which only require being screwed in order to fix them to the ground or to the walls with a high capacity of adaptation to the latter due to their articulated anchoring and assembly elements, facilitating the installation and reducing the assembly time.

Description of the Invention

Consequently the invention is essentially based on two grooved tubular metallic profiles (one round profile and another oval profile) and pre-assembled articulated mechanical elements for making modular articulated gratings or railings.
Both the round and the oval tubular metallic profile are used for vertical elements (struts) and horizontal elements (handrail, body, stringers and the like), and have three types of rigid fixings for fixing to the ground for installations received, screwed in a bed plate and screwed to a flooring edge in addition to an articulated foot for adapting to slopes.
The attachment between horizontal and vertical elements is emphasized by the type of developments to be carried out and can be made either by means of an abutment which is inserted in the groove of the tubular metallic profile in which an articulated cramp is fixed allowing the incorporation of all types of panels for making the body, such as boards made of wood, phenolics, composites, glass, solar panels, etc..., or a support for a cable or with a crosshead formed by two abutments which are inserted in the groove of the metallic tubular profile or embedded in the solid profiles which, according to their configuration, allows the assembly between two tubular metallic profiles or between a metallic profile and another solid profile.
A butt hinge-ball joint assembly is used for assembling the upper horizontal element, which can be a solid or tubular profile, which assembly allows it to rotate on the axis of the strut in addition to adapting to the installation plane.
From the assembly idea it is deduced that all the members integrating it are planned and developed to adapt, with their particular designs, to the main members of the structure which is designed and calculated so that, without needing the intervention of means specially required for specific works, they can exceptionally be installed on-site on any type of surface, in which the means designed for this purpose and integrating the assembly comply with the linearity of the installation, maintaining the horizontalness of its stringers, crosspieces or others and the adaptation of its struts to the profiles of the terrain or surface on which they are assembled.
Emphasis is made on the fact that the absence of means that do not correspond to the assembly described in the patent makes the assembly of the installation especially agile and safe, whatever the demands thereof may be upon having solved all the mechanical application, adaptation and assembly situations with complementary members perfectly and efficiently adjusting to the basic main elements which are the vertical and horizontal tubular supporting profiles.

Description of a Preferred Embodiment of the Invention

This description is centered on the corresponding illustrations of the depictions of the invention, based on the following aspects:
The arrangement of the tubular metallic profiles, a round profile (1) (Figure 1) and an oval profile formed by the profiles (71) and (72) (Figure 2), are elements which by their structure and geometry are used both for vertical elements (hereinafter struts) and for horizontal elements (hereinafter crosspieces or handrails) for constructing gratings, fences or railings, and have one or four grooves (5) respectively and a batten (2) consisting of two longitudinal teeth (6) for their clipping in the grooves (5). The oval profile is assembled by fitting the projections (76) of the profile (72) in the grooves (77) of the profile (71) which in turn fits its face (74) in the groove (75) of the profile (72), and finally being attached by the screws (73). Each profile, (71) and (72), has one groove (5) and the tongue and groove joint of both creates two more grooves (5).
There is a butt hinge-ball joint assembly (Figure 3) for assembling the upper elements of the gratings, fences or railings, which assembly is formed by a base (9) of the butt hinge with a central borehole (18) in which the butt hinge (8) is introduced and is kept fixed by assembling in its lower threading (17) the nut (11) with the washer (10) which is supported on the plane (20) of the cover (9), allowing the butt hinge (8) to freely rotate on its axis. The threading (16), finished with the tip (98), in which the ball joint (7) is screwed in, is at the upper part of the butt hinge (8). The butt hinge-ball joint assembly (Figure 3) is assembled on the strut, fitting the milled cylinder (21) of the base (9) of the butt hinge in the channel (3) of the strut (1), placing this milling (21) against the face (23) of the channel (3) and screwing in the screws (22) in the open tubular channels (4) of the strut (1) (Figure 1), which screws are introduced in the boreholes (19) of the base (9) of the butt hinge.
The round strut (1) has four types of fixings for fixing to the ground, three rigid fixings (Figures 4a, 4b and 4c) and one articulated fixing (Figure 5). Figure 4a is a received installation of the strut (1) in which the tube (24) is introduced in its channel (3) at one end and is inserted in the bed plate at the other end, intercalating the trim (25), its base (27) being coplanar with the ground and provided with a borehole (28) for the passage of the tube (4) and a recess (26) for fitting the strut (1). The strut is fixed by means of the plate (29) which is introduced in the groove (5) of the strut (1) and by means of the stud bolts (31) screwed in the boreholes (30) of the plate (29) exerting a deformation of the bottom of the groove (5) and creating a firm attachment of the strut (1) to the tube (24). Figure 4b is an installation screwed to a bed plate in which the tube (24) is welded inside the borehole (34) of the base plate (32) having three boreholes (33) for its fixing to a bed plate by means of the plugs (35). The strut (1) is fixed to the tube (24) by means of the plate (29) as in the assembly of Figure 4a. In the assembly of Figure 4c to a flooring edge, it is the plate (29) which is welded to the anchoring plate (36) provided with the three boreholes (33) for the fixing by means of the plugs (35), and the strut (1) is fixed by introducing the plate (29) in its groove (5) and pressing with the butt hinges (31).
The articulated foot of Figure 5 is formed by a base (41) with a lower support surface (46), a central hollow (48) and an upper spherical surface (47) on which the body (39) is supported, which body is provided with a spherical indentation (49), a borehole (51), a central hollow (53), a recess (55) at its lower part for fitting the base of the screw (40) and an upper hollow (54) for fitting the centering element (38). The tube (24), on which the strut (1) is fixed by means of the plate (29) and the stud bolts (31), traverses the centering element (38) through its borehole (57), the body through the hollow (53) and has an inner threading (58) at its lower end which is screwed on the screw (40), maintaining the assembly of these four parts firmly attached. The assembled assembly is coupled on the base (41), the assembly being pressed by the nut (44) and the washer (43), which is seated on the plane (52) of the body (39), screwed in the stud (42) received in the ground and traversing the base (41) through its hollow (48) and the body (39) through its borehole (51). The protector (37) is finally installed by fitting in the tongue and groove joint of the back (56) of the body (39) and screwing in the borehole (50) of the body (39) the screw (45) introduced in the borehole (78) of the protector.
Figure 6a is an assembly of the articulated foot for the oval strut (71) and (72) formed by a base (80) with a central hollow (82), a planar seat (83) which is supported on the ground and a spherical surface (81) on which the spherical indentation (84) of the lower face of the body (79) is seated, which body is equally provided with a central hollow (89) and with four ribs (85) fitting in the channels (86), (87) and (88) of the strut (71) and (72). The firm fixing is carried out by means of the stud (42), received in the ground, passing through the central hollows (82) of the base (80) and (89) of the body (79), with the washer (43) seated on the plane (90) of the body (79) and with the pressure exerted by the nut (44) maintaining the assembly firm. Once the strut (71) and (72) has been fitted, it is fixed to the articulated foot by means of the screws (73) traversing the grooves (5) and they are fitted in the ribs (85) of the body (79).
Figure 6b shows the rigid assembly of the oval strut (71) and (72) to the ground by means of the body (91) of the planar base (92), with a central borehole (89) and four ribs (85) fitting in the channels (86), (87) and (88) of the strut (71) and (72). The firm fixing is carried out by means of the stud (42), received in the ground, passing through the central hollow (89) of the body (91), with the washer (43) seated on the plane (90) of the body (91) and with the pressure exerted by the nut (44) maintaining the body (91) firm. Once the strut (71) and (72) has been fitted, it is fixed to the articulated foot by means of the screw (73) traversing the grooves (5) and they are fitted in the ribs (85) of the body (91).
The abutment (59) of Figure 7a has a cylindrical face (60) with a central seat (66), a planar face (63) with two boreholes (61) and a central rib (64) having an upper cylindrical face with a borehole (62) and a seat (65). Figures 7b and 7c show the crosshead assemblies of two abutments (59) by means of the rivet (67) attaching the two parts through the central borehole (62), placing the seats (65) against one another or the seat (65) of one against the seat (66) of the other, allowing the abutments (59) to rotate freely with respect to one another, and with the screws (68) and/or (69) screwed in the boreholes (61).
Figure 8 illustrates the assembly of a solid profile (93) on the assembly of Figure 3 for making the upper parts of fences, gratings and railings. The solid profile (93) has a slot (94) in which the ball joint case (95) is housed and screwed with the screws (97), which case is provided with a hollow (96) in which the lugs (13) of the ball joint (7) fit. This system allows rotating the solid profile (93) with respect to the vertical axis of the strut (1) and inclining it on the axis of the lugs (13) to a maximum angle defined by the inclined planes (14) of the ball joint (7). Once the solid profile (93) is aligned with the plane of the ground, the position is fixed by driving the tip (98) of the butt hinge (8) in the bottom of the case (95) rotating the butt hinge (8) with a tool introduced in its borehole (15).
