    DESCRIPTION

    Registration Closure

    Object of the invention 5
    The present invention relates to an improved registration closure, which has a lid with a configuration that facilitates the opening maneuver of the lid and offers a safety lock of the lid in the open position, preventing the involuntary closure of said lid. top. In addition, the registration cover object of the invention has a safety lock to keep the cover fixed to the frame avoiding unwanted manipulations of the cover. 10

    Technical problem to solve and background of the invention
    In the state of the art, articulated registration covers that are opened by means of the use of levers are known, so that the cover articulates around an axis to separate from the frame and seeks a locked position when it has been opened. The opening of the lid with respect to the frame, according to current regulations must be at least 100º (EN 124: 2015).

    In the closures known in the state of the art, the connection of the cover to the frame is secured by screws that fix the cover to the frame and which must be removed in order to open the cover. This type of closure, since the closures are usually intended for use on roads with 20 traffic, are subject to numerous repeated efforts, so that they suffer from mismatches in the closure that usually lead to noise every time that over the closure passes a vehicle.

    These covers present a problem when opening them, since they are cast iron elements, they have a high weight and therefore the effort to be made when opening them is high, due to the above, it is desirable to obtain a lid that requires a smaller opening effort, since the opening and closing operation is carried out repeatedly by the workers during the course of their working day.

    Description of the invention
    The invention described discloses a registration closure with features that facilitate the opening maneuver of the lid with respect to the frame, and that locks the lid in the open position without such blocking requiring any effort on the part of the worker who is opening the lid. . 35


    The registration closure object of the invention comprises a frame and a cover, where the frame comprises a structure configured to accommodate the cover and an anchor surface.

    The frame additionally comprises a first housing comprising an inner curved surface, a final recess and side walls and the cover comprises a first projection comprising a flat end and an oblong hole, such that the cover is fixed to the frame by a pin that crosses the oblong hole and the side walls.

    The inner curved surface of the frame is configured to receive the flat end of the lid facilitating a maneuver of opening the lid with a turning movement of the lid, and 10 where the lid, in addition to the turning movement, has a linear displacement due to the oblong hole to lock the lid in an opening position with an angle between 100 and 140 °, with the flat end of the lid inside the final recess of the first frame housing.
     fifteen
    The frame of the registration closure object of the invention comprises a second housing and the cover comprises a second projection which in a closed position, where the cover is located inside the frame, coincides with the second housing of the frame.

    The registration closure object of the invention comprises a locking mechanism of the lid 20 on the frame, such that the locking mechanism comprises a protuberance perpendicular to the second projection, and where one end of the protuberance is fixed on a flange of the second housing .

    In one embodiment of the registration closure object of the invention, the protuberance is in the form of "L", such that one end of the L is fixed on the flange of the second housing.

    In the registration closure object of the invention the fixation between the protuberance and the flange is produced by elastic jump, so that in order to separate these elements from each other, it is necessary to force the protuberance to separate it from the flange. 30

    The registration closure object of the invention also comprises a security mechanism to prevent access to the locking mechanism. The safety mechanism comprises a screw in the second projection of the cover to be screwed into a specific hole located in the second housing. 35

    Finally, in the registration closure object of the invention, the anchoring surface of the frame comprises a plurality of holes for fixing the closure to a registration mouth.

    Preferred Embodiment of the Invention 10
    As already indicated, and as can be seen in the figures, the object of the invention is a registration closure comprising a frame (1) and a cover (2), and having characteristics that facilitate the opening maneuver of the cover (2) with respect to the frame (1), and that locks the cover (2) in the open position without such blocking requiring any effort on the part of the worker who is opening the cover (2). fifteen

    The framework (1) comprises:
    -a structure (3), inside which the cover (2) of the closure object of the invention is housed, and
    An anchoring surface (4) of polygonal shape at one end of the structure (3),
    -a first housing (5) configured to allow the cover (2) to rotate in that first housing (5), and
    - a second housing (6), which in the preferred embodiment of the invention, is located diametrically opposite the first housing (5).

    The anchoring surface (4) of the frame (1) comprises a plurality of holes (8) for anchoring the closure to the mouth of the register to be closed by, for example, screws that are threaded to the mouth of the register.

    The cover (2) of the closure object of the invention articulates in the first housing (5) of the frame (1) by means of a first projection (9) of the cover (2), and a pin (10) joining the cover (2) ) and the frame (1), so that it is the pin (10) that acts as the axis of rotation around which the cover (2) rotates.

    The first projection (9) of the cover (2) comprises a flat end (11) and an oblong hole (12) where the pin (10) is housed. 35

    The first housing (5) of the frame (1) comprises an inner curved surface (13) with a final recess (14) and side walls (15) comprising holes.

    To facilitate the opening maneuver of the lid (2) and prevent its closing in the open position, the flat end (11) of the first projection (9) of the lid (2), during the opening maneuver, is supported on the inner curved surface (13) of the frame (1), this inner curved surface (13) is configured so that when the lid (2) reaches 45 ° opening it contributes to the lid (2) turning supported on the surface inner curve (13) reducing the effort to be made when lifting the lid (2), and when the lid (2) reaches 120 °, the flat end (11) of the lid (2) reaches the final gap (14 ) of the first housing (5), the lid (2) being locked in that position since due to the interaction of the oblong hole (12) of the first projection (9) and the final recess (14) of the first housing (5) the lid (2) open in the 120º position is locked.

    The cover (2) comprises a second projection (16), which in the preferred embodiment of the invention is diametrically opposed to the first projection (9) to coincide with the second housing (6) of the frame (1).

    In the second housing (6) a locking mechanism (7) of the cover (2) is placed on the frame (1), thus the cover (2) is fixed on the frame (1) with a locking mechanism ( 7) "click" type, such that the locking mechanism (7) comprises an "L" shaped protuberance (17) extending perpendicular to the second projection (16), such that by elastic jump, a branch of the L is fixed on a flange (18) located inside the second housing (6). Thus, in order to open the lid (2) it is necessary to apply a force on the protuberance (17) to overcome the elastic jump fixing. 25

    Likewise, the closure object of the invention comprises a safety mechanism to prevent access to the locking mechanism (7), which has a screw (19) in the second projection (16) that is screwed into a specific hole (20) located in the second accommodation (6). 30

    The cover (2) comprises lower reinforcements () configured by radial ribs, which start from a central polygon to the end of the cover, having a greater thickness in the central polygon and reducing its thickness as they approach the perimeter of the cover (2).
     35
    The closure object of the invention comprises a joint (21) of 360 ° which is arranged between the
    cover (2) and the frame (1), specifically inside the structure (3) of the frame (1), so that the cover (2), in a closed position, rests on the gasket (21) and generates sealing in closing.

    The invention should not be limited to the embodiments described in this document. Experts in the field can develop other embodiments in view of the description made here. Accordingly, the scope of the invention is defined by the following claims.
