    System and procedure of union removable and adjustable in angle by means of which join profiles of round tube (1,2) of different diameters. The system consists of two groups of two flanges, a base flange (3) and an adjustment flange (4) movable with respect to the base flange, which are coupled together by means of screws (9) and inside which are wedged in the shape of dovetail cone (5). This ensures the independent tightening of each profile (1, 2) and thus adjusting to the desired diameter. Both groups are joined by a screw (10) and its respective nut (11), allowing the rotation between them and thus be able to join them at the desired angle. By means of this system, it is possible to join different round tube profiles without the need to carry out previous operations. (Machine-translation by Google Translate, not legally binding)

    DESCRIPTION

    System and procedure of union adjustable in angle for profiles of round tube of different section.
     5
    Technical sector

    The present invention has application in the field of removable joints for metal structures, specifically in the assembly of circular section tube profiles.
     10
    Background of the invention

    There are currently removable and adjustable angle joints on the market for joining circular section profiles, but these systems only allow the connection between profiles of the same diameter. To our knowledge, there is currently no joining system 15 that simultaneously meets the following characteristics: a) no prior preparation of the profiles to be joined is needed, b) it is a fully removable system, c) it allows the total variation of the angle of union between the profiles, without changing the union system used, d) is valid for the simultaneous union of profiles of circular section of different diameter. twenty

    Explanation of the invention.

    The present invention describes a removable and adjustable joining system and method for round tube profiles (1, 2). This system consists of two groups of two flanges and five 25 wedges (5). Each group consists of a base flange (3), an adjustment flange (4) with respect to the base flange and wedges (5) mounted on each of the profiles to be joined (1, 2).

    The base flanges (3) have an annular shape (figure 2), with a flat part (14) in the contact area with the adjacent flange and consist of dovetail-shaped chamfers (6) through which circulate the wedges (5). They are also provided with five threaded holes (7) located parallel and distributed circumferentially on a regular basis, through which the screws (9) pass, which are the means of fastening the base flange with the adjustment flange (4). The connection between the base flanges is produced by means of a screw (10) and its corresponding nut (11), so that the desired angle between the profiles (1,2) can be set (Figure 5). The screw passes 35 through a hole (8) which in turn consists of a cover (12) which allows the wedge (5) to slide easily (Figure 5).

    The adjustment flanges (4) in turn have an annular shape (Figure 3) with a flat area (14). In addition they consist of five drills (13) located parallel and distributed circumferentially 40 on a regular basis, in which the screws (9) and five projections of conical dovetail (15) like the wedges are housed. These flanges can be adjusted so that the wedges fit the diameter of the tubular profiles (1, 2)

    On the other hand, the wedges (5) are shaped like a conical dovetail to prevent said wedges from falling from the base flange when the profiles (1,2) are removed, and the conical shape allows them to adjust by pressure . In this way it is possible, that when the adjustment flange is pressed against the base flange by means of its corresponding screws (9), the adjustment flange pushes the wedges into the dovetail-shaped inserts until the tubes to be joined are firmly tightened . fifty

    As a consequence, with the described system, it is possible to make removable joints at different angles between two round tube profiles (1, 2) of different diameters. In addition, its easy assembly and disassembly, guarantees the possibility of reuse of the parts
    involved in the union, such as the profiles (1, 2) and the components of the union, without having to carry out previous operations on the profiles.

    Preferred Embodiment of the Invention

    Taking into account the numbering adopted in the figures, the embodiment of the invention is described below.

    The joint system described comprises a total of two groups of four flanges, where two of 35 are base flanges (3, Figure 2) and the other two are adjustment flanges (4, Figure 3) coupled together by screws (9 ), and 5 wedges (5, Figure 4) mounted on each of the profiles to be joined (1,2).

    In relation to the procedure, it comprises the following stages: 40

    First, the screw (10) is inserted into the bore (8) of both base flanges (3) and tightened with its corresponding nut (11) leaving the desired angle between the profiles (1,2). Then, to close the hole in the hole, put the plug (12) on both base flanges (3) (see Figure 5). Four. Five

    Next, each wedge (5) is placed in its respective chamfer (6) present in the base flanges (3) (see Figure 6). Once placed, the adjustment flange (4) is placed on top, so that it coincides with the conical dovetail-shaped projections (15) such as the wedges, and the screws (9) are introduced without firmly tightening in their respective holes (7 and 13) 50 thus joining the base flange assembly (3) and adjustment (4) (See Figure 8).

    Finally we take the tubular profiles (1,2) that we want to join, we introduce them by means of the joined flanges and tighten the screws (9) firmly until the profiles (1,2) are well secured (See figure 1).
