    DESCRIPTION
    Locking device for suspended duct supports OBJECT OF THE INVENTION
    The present invention belongs to the field of devices for joining or blocking construction elements, and more specifically to mechanisms for fixing and blocking brackets for telecommunications conduits, air conditioning pipes, electrical wiring, etc., which require their installation in suspension to certain height
    The object of the present invention is a locking device that in addition to guaranteeing a secure and stable fixing of supports for suspended conduits with respect to threaded rods, without gaps or unwanted movements of the supports, also provides a fast and comfortable installation and uninstallation of the same by the installer.
    BACKGROUND OF THE INVENTION
    At present, various types and configurations of duct supports are known in the state of the art, which require a height layout, that is, located in suspension from ground level, and used in all types of facilities (telecommunications, air conditioning, electricity, plumbing, etc.).
    More particularly, these supports are fixed in suspension to ceilings by means of the use of small accessories, destined to constitute a support, to hold shelter and / or to keep the conduits in a safe and stable position. Thus, in the simplest version these supports consist basically of metal plates, on which the duct is directly supported, provided with at least one through hole, internally threaded nuts and locknuts in which a generally anchored threaded rod is inserted or fixed in turn to the ceiling or a top beam.
    Other more complex solutions, in addition to the above, include at the lower end of said threaded rods a second support, clamp or final accessory that contacts

    directly with the conduit to support. By way of example, patent application EP0905390 A2 can be cited.
    However, in relation to the current "fixing mechanisms" of supports for suspended ducts that have threaded rods, there are still several drawbacks to which an effective and complete solution has not yet been provided, namely:
    - Due to its structural simplicity (nut, locknut and rod), and the high weight and length, both of the supports themselves and of the conduits to be supported, the current fixing mechanisms have problems of efficiency, strength and durability, not only with the time, but also during the installation / uninstallation of them mainly in height, suffering slacks, mismatches and unwanted movements of the supports, which can result in accidents and falls of the supports and conduits.
    - Its threading mechanisms are fully exposed to the outside, and do not have any means of protection against possible shocks or external environmental conditions, which causes variables such as humidity, dust particles in suspension or even the continuous changes of temperature, they can affect its normal operation, causing oxidations and jams in its thread fillets, and consequently hindering any subsequent maintenance, repair or replacement of parts.
    - The installation times are clearly optimizable, because because it is a task to perform at height, as well as the fact of having to manipulate and couple several independent pieces together, the process is somewhat complex and requires some expertise and experience to part of the technical installation staff.
    - In addition, the current assemblies formed by fixing mechanism, threaded rod and support have an important limitation in that they do not allow the realization of a fine adjustment in height, that is, a regulation or fixing more concrete, smooth and / or specific for each case, during the installation and uninstallation tasks.

    DESCRIPTION OF THE INVENTION
    By means of the present invention, the aforementioned drawbacks are solved by providing a blocking device that, in addition to guaranteeing a secure fixation of the supports with respect to a threaded rod, understood as supports for accessories such as brackets, brackets, crossbars, profiles, gwas, plates and similar, intended to fix and support pipes, channels, gutters and trays or even the latter without the intervention of the aforementioned accessory, in any of the cases mentioned intended for the support and maintenance in stable position of conduits, tubes or cables in suspension, hereinafter simply called "ducts", it constitutes an easy-to-use solution for a comfortable, safe, versatile and quick installation / uninstallation by the installation personnel. Likewise, the blocking device described here provides additional protection and safety of its components against conditions external environmental such as humidity, part dust iculas, etc.
    The blocking device for duct supports, object of the invention comprises a housing having side walls, an upper wall, and at least one hole in which a threaded rod is inserted; a pair of pins located inside the housing preferably at an angled angle with respect to the axial vertical axis of the housing; a first spring also housed inside the housing; and a pair of primary bodies, mounted on the first spring, where said primary bodies are pushed by the first spring against the inner upper wall of the housing, and are arranged facing each other in an upper and inner area of the housing.
    These primary bodies, mentioned above, have an internal thread, complementary to the threaded rod, and a through hole, preferably inclined, in which an upper end of the pins is inserted, said primary bodies being movable on the pins, in particular in the sense of the latter.
    Thus, when there is a movement of insertion of a rod in the housing, and since the force exerted for such insertion is greater than the force exerted in the opposite direction by the first spring, the primary bodies tend to move towards the side walls of the housing and inferiorly in the direction of the pins, compressing to its
    5
    10
    fifteen

    25
    30
    First time spring. In this position, the internal threading of the blocking bodies does not act with respect to the threaded threads of the rod, allowing the insertion and advancement thereof, without any blocking element.
    On the other hand, when the rod insertion movement ceases, traction of the first spring is produced in the opposite direction to the one described above, this performing a vertical thrust force on the primary bodies in the opposite direction to that of a rod insertion, and consequently, moving these again towards the upper and central part of the housing through their respective pins, until their internal threads are contacted with the threaded rod for its definitive locking. In this way the threads of both elements (primary bodies and rod) act as stop elements, which by contacting each other prevent the movement of the rod backwards, that is, preventing the rod from leaving with respect to the body of the housing , but allowing the actuation of the rod by threading.
    Therefore, in a first initial or resting position, the primary bodies are located by the action of the first spring, at the top of the pins, next to each other and forming both a single body. Thus, when proceeding with the introduction of a threaded rod, said primary bodies are separated by moving towards the bottom of the pins, sliding through it, for later, once the rod is released, that is, once it is stopped doing Pressing or acting on it, said primary bodies return to their upper initial position, then blocking the rod by means of the internal threading of said primary bodies with respect to the thread thread of the rod.
    Preferably, the locking device of the invention additionally comprises a first auxiliary locking element connected to the housing in correspondence with the inlet hole, also being provided with a through hole for inserting a rod; and a second auxiliary blocking element attachable in the first auxiliary blocking element. These auxiliary blocking elements make it possible to provide two additional blocks of both the support and the rod, three being therefore the simultaneous blocks obtained by means of the device of the invention.

    Thus, the primary bodies provide a first locking of the threaded rod, its components being fully protected and encapsulated within the housing. In this regard, the second auxiliary blocking element also allows the first blocking element and the secondary bodies to be provided with protection and insulation against external environmental conditions, so that the respective thread fillets are intact and protected from the outside.
    On the other hand, it is envisaged that the blocking device described herein may also be included or coupled in an accessory of the aforementioned (brackets, brackets, crossbars, etc.) that support pipes to house ducts, this application being especially useful in those cases where the rods are anchored to the ceiling, so that by simply unscrewing the second locking element the device of the invention can be inserted into the rod at the desired height, thus making a fine adjustment, or not, and again by screwing said second blocking element effect the definitive blocking of the whole assembly.
    Therefore, by means of the blocking device of the invention, the passage of threaded rods in one direction is allowed, blocking them in the opposite direction with respect to the support. In addition, the blocking device described herein has independent mobility with respect to the support, which allows the installer to make a fine and precise adjustment of the support, without any risk, and with the ability to block and stop the rotation of the supports in the place where it requires the installation, as well as the blocking of the whole assembly formed by support, rod and blocking device object of invention. Therefore, a comfortable, fast and efficient solution is provided, which allows the installer to perform coupling / uncoupling and adjustment actions of suspended duct supports with respect to threaded rods, considerably reducing installation times, with greater maneuverability and safety. , and contributing accordingly to avoid accidents at the time of undertaking these tasks.

    PREFERRED EMBODIMENT OF THE INVENTION
    A couple of examples of preferred embodiment are described below, mentioning the figures mentioned above, without limiting or reducing the scope of protection of the present invention.
    In Figure 1, a first embodiment of the blocking device (1) of the invention can be seen, which comprises:
    - a housing (10), which in this first example has an upper wall, side walls and a pair of coaxial, upper and lower holes (11, 12), in which a threaded rod (B) is inserted, the latter shown in figures 2E-2H;

    - a pair of pins (20) located inside the housing (10) at an angled angle (a), in a symmetrical position with respect to the axial vertical axis (E) of the housing (10), and whose upper ends converge with each other towards said vertical axis (E), as shown in Figure 2A;
    - a first spring (30) housed inside the housing (10), in an intermediate position between the two pins (20) and the two upper and lower holes (11, 12) of the housing (10), and inside which threaded rod (B) is also insertable;
    - a pair of primary bodies (40), mounted on the first spring (30) which pushes said primary bodies (40) against the upper inner wall of the housing (10), where said primary bodies (40) are arranged facing each other in an upper and inner area of the housing (10), for blocking the rod (B); and in turn have an internal thread (41), complementary to the thread of the rod (B), and a through hole (42) and inclined in which an upper end of the pins (20) is inserted, the bodies being primary (40) movable on the pins (20), in the sense of the latter;
    - a first auxiliary locking element (50) attached to the housing (10), in which example both elements (10, 50) constitute a single body, corresponding to the upper hole (11), and in which it is equally insertable the rod (B);
    - a second auxiliary blocking element (60) attachable in the first auxiliary blocking element (50) for fixing the rod (B);
    - a second spring (70) housed inside the first auxiliary locking element (50); Y
    - a pair of secondary bodies (80), partially inserted on an upper end of the first auxiliary locking element (50), and provided with an internal thread (81), complementary to the threaded rod (B).
    In addition, according to this first preferred embodiment, the locking device comprises a base cover (13), shown in Figure 1, inferiorly coupled to the housing (10), and having a central hole (13a) for the passage of the rod (B) and a pair of blind side holes (13b) inclined for the insertion of a lower end of the pins (20). This feature allows to strengthen and ensure even more if the correct positioning of the pins (20) fits, providing a double clamping of these,
    5
    10

    superiorly by means of the through holes (42) of the primary bodies (40), and inferiorly by means of said blind lateral holes (13b). More preferably, it is provided that the through holes (42) of the primary bodies (40) are inclined holes, which facilitates the angled arrangement of the pins (20) inside the housing (10), ensuring optimum coupling and positioning of them.
    At this point it should be noted that the particular angle arrangement of the pins (20), as well as the relative position between said pins (20) and first spring (30), allows it to be the rod insertion movement itself, without element additional one, the one that causes the separation or approximation of the primary bodies (40), and consequently the passage or blockage of the rod (B).
    Thus, figures 2A-2H show sectional views where the installation process of the locking device (1) of Figure 1 is shown on a support (A), in this case represented as a simple horizontal metal plate but referred to both to a surface of a conventional support such as mensula, square, traverse, profile, guide or similar suitable for supporting pipes such as channels, gutters or trays that house ducts, as well as to a surface of any of the mentioned pipes without participation of said conventional support, provided with a hole; and the subsequent fixing of said support (A) and a threaded rod (B) inserted into the housing (10).
    More specifically, in Figures 2A and 2B the blocking device (1) is observed approaching the support (A) inferiorly according to the arrow shown, for insertion of the first auxiliary blocking element (50) in the support (A), or vice versa, where in this case said first auxiliary locking element (50) and housing (10) constitute the same body, thus reducing the number of independent parts to be handled, facilitating its installation and reducing manufacturing costs.
    Then, as seen in Figure 2C, the second auxiliary blocking element (60) is coupled to the first auxiliary blocking element (50). Thus, in this example of preferred realization, the first blocking element (50)
    5
    10
    fifteen

    25
    30
    auxiliary has an external thread (52), while the second auxiliary locking element (60) has an internal thread (61), such that the coupling and closing between both blocking elements (50, 60) is obtained by the action and joint connection of their respective threads (52, 61), without more than turning said second auxiliary locking element (60) according to the arrow shown in Figure 2D.
    Thus, as shown in Figures 2E and 2F, when a rod (B) is inserted into the housing (10), the displacement of the primary bodies (40) towards the side walls of the housing (10) occurs. and inferiorly in the same inclined direction of the pins (20), in turn compressing the first spring (30). In this position, represented in Figure 2F, the internal threading (41) of the primary bodies (40) does not act on the threading of the rod (B), allowing the free insertion of the rod (B) as much as wish.
    In relation to the first spring (30), it is in a stable position through its upper and lower partial insertion in projections provided both in the lower part of the primary bodies (40), and in the base cover (13) around of the central hole (13a) mentioned above, as shown in Figures 1, 2A-2H. Therefore said first spring (30) is in a fixed position. At this point, it should be noted that when it is said here that the first spring (30) is compressed or decompressed, it does so minimally, just the equivalent of a thread fillet of the primary bodies (40) and therefore enough to allow passage of the rod (B) without acting the inner threads of the primary bodies (40), therefore these primary bodies (40) are also spaced apart, without reaching the lower end of the pins (20).
    On the other hand, when the rod (B) stops acting and the insertion movement ceases, the first spring (30) begins to act and due to its own traction movement, as shown in Figure 2G, said first spring (30) executes a vertical thrust force on the primary bodies (40), consequently displacing the latter towards their initial position through their respective pins (20) until their internal threads (41) are contacted with the threading of the rod (B). It is after this step, shown in Figure 2H, that there is a first blockage of the rod (B), because when contacting its
    5
    10
    fifteen
    twenty
    25
    30
    respective threading and acting as stop elements, it is possible to prevent a backward movement of said rod (B), but by enabling the rotation of the rod (B) with respect to the internal threads (41) of the primary bodies (40), for make a fine adjustment by the installer in terms of the most suitable height where to leave the support positioned.
    Next, the auxiliary support blocks (A) and the rod (B) are explained according to this first example of the blocking device (1), shown in Figures 2G and 2H, which would constitute a second and third additional block. to the first block already described above.
    With these auxiliary locks, it is not only possible to block the retraction of the rod (B) again but also to prevent the movement of the rod from advancing, also guaranteeing a fixed and stable position of the support (A), for which both the first and second auxiliary blocking elements (50, 60), such as the secondary bodies (80) mentioned above.
    More specifically, in Figure 2G it can be seen that the upper end of the first auxiliary locking element (50) has a chamfer provided with an inclined internal surface (51). On the other hand, the secondary bodies (80) have a conical and semicircular shape, in turn provided with an inclined external surface (82) intended to contact the internally inclined surface (51) of the first auxiliary locking element (50) in solidarity. . In this way, the coupling and closing of the second auxiliary blocking element (60) with respect to the first auxiliary blocking element (50) causes the downward thrust and sliding of the secondary bodies (80), these approaching each other until they contact their internal threads (81) with the threaded rod (B), blocking and preventing the advance of this. It should be noted that this movement of thrust and sliding of the secondary bodies (80) causes at the same time the compression of the second spring (70), as shown in Figure 2H. Thus, unscrewing by the installer of the second auxiliary locking element (60) would cause the traction of said second spring (70), and consequently the pushing and sliding up of said secondary bodies (80).
    5
    10
    fifteen

    25
    30
    In this regard, it is provided that the secondary bodies (80) may have a transverse recess (83) in "U", shown in Figure 1, arranged on their upper face and that start from their internal thread (81) to its external side walls In addition, the possibility is contemplated that the second auxiliary locking element (60) has a pair of upper stops (62), which project horizontally towards the center of said second blocking element (60) without get to contact each other, leaving between said upper stops (62) a sufficient distance to allow the insertion of a threaded rod (B).
    Thus, the coupling of the second auxiliary blocking element (60) in the first auxiliary blocking element (50) causes the contact and thrust of said upper stops (62) over the transverse recesses (83) of the secondary bodies (80), thus helping the pushing and sliding of said blocking bodies (80) on the inclined internal surface (51) of the first auxiliary blocking element (50).
    In addition, with respect to the third lock, in the complete closing view of Figure 2H, the fixing of the support (A) is shown, this being firmly pinched superiorly by the second auxiliary blocking element (60), and inferiorly by the upper wall of the housing (10), without the possibility of unwanted gaps or movements of the support (A), such as the rotation of the support (A) with respect to the rod (B), or upwards, this is towards the second element of auxiliary locking (60), when the assembly formed by locking device (1), support (A) and rod (B) is in its final position or assembly.
    On the other hand, in Figures 3, 4, 5A and 5B a second example of the blocking device (1) of the invention can be seen, where the first blocking of the rod (B) by the primary bodies (40) , with the intervention of the pins (20) and the first spring (30), it is analogous to that described for the first example, and where the main differentiating characteristics with respect to the first example are:
    - the first auxiliary locking element (50) is an elongated and hollow cylindrical tube, shown in Figure 3, into which a threaded rod (B) is inserted, having its
    5
    10
    fifteen
    twenty
    25
    30
    side wall hollow recesses (56) whose upper end projects first and second flexible flanges (53, 54), oriented inferiorly towards the housing (10); Y
    - the second auxiliary locking element (60) is a nut provided with an internal thread (1), as shown in figures 3 and 4, providing simplicity to the locking device (1) of the invention, in par which protection of the flexible eyelashes (53, 54) mentioned above.
    Therefore, in this second example, the second spring (70), the secondary blocking bodies (80), as well as the cover (13) are dispensed with, the housing (10) forming a single closed body, provided in this case with two upper and lower holes, analogous to those shown in Figure 2A, to allow the insertion of a rod (B). In this second example, the first spring (30) rests on projections provided only in the lower base of the housing (10), as shown in Figures 5A and 5B.
    More particularly, in Figure 5A it can be seen that the first flexible flanges (53) have a distal end in "L" (53L) that converges towards the side wall of the cylindrical tube (50). In this way, the coupling and closing of the nut (60) on the cylindrical tube (50) causes the thrust into said first flexible flanges (53), causing its distal end at "L" (53L) to contact the threaded the rod (B) blocking the advance of it, as shown in Figure 5B, this being a second block provided by the device of the invention.
    On the other hand, the second flexible flanges (54), shown in Figures 5A and 5B, have an inclined ramp shape, with its divergent distal end and projected outward from the cylindrical tube (50). Thus, the coupling and closing of the nut (60) on the cylindrical tube (50) causes said second flexible flanges (54) to contact the internal thread (61) of the nut (60), preventing the recoil movement, or unscrewed said nut (60), acting as a thread guide.
    Furthermore, in Figure 3 it can be seen that the cylindrical tube (50) has at least one tongue (55) projecting horizontally from the lower edge of said cylindrical tube (50)
    outward. This tab (55) allows the cylindrical tube (50) to be anchored and secured securely in the housing body (10), preventing unwanted leakage or escape of said cylindrical tube (50).
    5 Thus, the third blockage occurs when finally the support (A) is firmly locked superiorly by the second auxiliary blocking element (60), and inferiorly by the upper wall of the housing (10), without the possibility of gaps or unwanted movements of the support (A), such as the rotation of the support (A) with respect to the rod (B), or towards the second auxiliary blocking element (60), when the assembly 10 formed by a blocking device ( 1), support (A) and rod (B) is in its final position or assembly.
