    [0002] Closing device for doors and gates of livestock enclosures
    [0003] Technical sector
    [0005] The present invention refers to a closing device for doors of agricultural or livestock facilities, which provides greater security to said facilities, making it impossible for livestock to open the door of the enclosure in which they are located.
    [0007] State of the art
    [0009] Livestock is an economic activity of very ancient origin that consists of the management and exploitation of domesticable animals for production purposes. For this, it is usual to share the cattle in different enclosures, either for the separation by species, age, sex, etc ...
    [0011] These enclosures for livestock require access doors that allow the entry and exit of both the livestock, as well as the people and equipment necessary for the care of the livestock. Doors for enclosures of this type are known that comprise closing devices that comprise a projection with a through hole and a vertically projected bolt, so that, when the bolt is inserted into the hole, the opening of the door is prevented due to its own Weight of this, this has the additional benefit that the bolt / hole assembly can perform the function of a hinge, allowing the angular movement of the door in case it is decided to open from the opposite edge of the door.
    [0013] These closing devices are not entirely safe since they are opened using force on a single mechanism, it has been proven that cattle, especially pigs, are capable of opening these closing devices by using force with one of their extremities (generally the nose) on said mechanism, producing the opening of the door, so that the cattle can escape from the enclosure, causing serious losses of money.
    [0015] Closing devices are known to solve this problem, such as the one contained in the utility model ES10700370U, which have a movable element that abuts vertically, so as to prevent accidental opening of the door.
    [0016] The main disadvantage of this type of closing device is that there is the possibility that the movable element will move, for example in the case of many vibrations due to the continuous ramming of the cattle, allowing the door to be opened.
    [0018] Another well-known solution is the one contained in the utility model ES1142810U, which has, like the previous one, a movable element that abuts vertically, but has a diagonal slot on one of its faces through which it has to move. the gripping means, which makes it difficult to accidentally open the closure device, but does not completely eliminate this possibility.
    [0020] Another disadvantage of both solutions lies in the need to make cavities, either in the door itself and / or in the enclosures (whether they are walls, partitions, panels, etc ...) in which the door is placed, for installation of these closing devices.
    [0022] Therefore, it is necessary to have a closing device for doors of livestock facilities that incorporates an additional element that makes it impossible for livestock to open the door, assuming a more secure alternative to known solutions, and that requires less destruction of the door and / or enclosure.
    [0024] Object of the invention
    [0026] For all the foregoing, the object of the present invention is a closing device for a door of livestock facilities, which comprises:
    [0027] • a casing fixable to a door edge and connectable as a hinge to an enclosure, the hinge-like connection being separable by vertical displacement of the door;
    [0028] • a handle with a locking stop, the handle pivotally connected to the housing between a locked position and an unlocked position, in which the vertical displacement to separate the door is respectively held or released, by means of the blocking stop against the enclosure; and
    [0029] • a retainer configured to retain the pivot of the handle in the locked position.
    [0031] All this allows the closing device to avoid accidental opening of the door because the retainer prevents the pivoting of the handle from the position in which the stopper stops. The lock retains the door gap, to which the locking device is attached with the lock. An additional security element is added that prevents the animals from separating the door with the constant lunges, being easily releasable by the user, in addition to providing an easy device to manufacture and install.
    [0033] The hinge-like connection is a conventional connection as is already known in the state of the art, being for example a bolt included in a projection of the casing that connects in a tongue-and-groove with a hole made in the enclosure, or according to another embodiment It can be a projection of the casing with a hole that connects in a tongue-and-groove with a bolt included in the enclosure, the bolt being capable of acting as a pivot axis for the door in both cases. This allows angular movement of the door, should it be decided, for various reasons, to open the door from the end opposite the device.
    [0035] It should be mentioned that, depending on the needs of the livestock facility, for which the closure device is designed, the enclosure to which the closure device is connected could be a wall, fence, panel, etc ...
    [0037] The locking stop is integral at the end of the handle that acts as a pivot axis, in such a way that when the handle moves, the locking stop also moves in the same direction and around the same pivot axis.
    [0039] When the closure device is in the locked position, the retainer retains the handle, leaving the handle in a horizontal position. In said locking position, the handle locking stop is in a position superior to the connection of the casing with the enclosure, in such a way that, when the casing is connected to the enclosure, for example in a drawer made in the enclosure itself, the locking stop prevents the vertical movement of the door when it collides with the upper surface of the drawer unit or top of the enclosure to which the casing is connected.
    [0041] When the device is in the unlocking position, both the handle and the stop are in a vertical position, the blocking stop being parallel to the edge of the enclosure, eliminating the contact of the locking stop with the enclosure door.
    [0042] Additionally, the retainer is pivotally connected to the housing, said retainer being configured to engage the handle in a retention position, which prevents pivotal movement of the handle from the retention position in which the retainer engages the handle. .
    [0044] Furthermore, the retainer comprises return means to automatically return to the retention position, in particular by gravity or spring.
    [0046] Both the handle and the retainer are designed in such a way that, either by gravity or spring, they pivot automatically, to their locking and retention position, allowing automatic engagement between the retainer and the handle, which increases the safety of the device and facilitates simple and fast actuation of the closing device.
    [0048] Preferably the retainer is designed so that its center of mass is located in a section of the retainer different from the pivot axis of the retainer itself, so that, by its own weight, it automatically pivots to its retaining position. The same happens with the handle that by its own weight pivots to the locked position.
    [0050] Additionally, the retainer is substantially flat, which facilitates the manufacture of the retainer, lowering the cost of manufacturing the closure device.
    [0052] In addition, the retainer comprises a projection pusher substantially perpendicular to the plane of the retainer, such that by grasping the handle, when it is engaged to the retainer, it is possible to easily move the pusher so that the retainer moves out of its position. retention allowing pivoting movement of the handle.
    [0054] The housing comprises a retainer stop configured to stop pivoting of the retainer in the retaining position, allowing the retainer not to automatically move beyond its retaining position, allowing automatic engagement with the handle.
    [0056] Likewise, the casing comprises a handle stop configured to stop the pivoting of the handle in the locked position, allowing the handle not to move automatically beyond its locked position, allowing automatic engagement with the retainer.
    [0058] The handle is angled at an end opposite the locking stop, allowing a better grip of the handle when opening the door, preventing the handle from sliding during its grip when the door is moved vertically.
    [0060] In addition, it is envisaged that in a preferred embodiment the closure device comprises a frame that can be fixed to the closure, the casing being connectable as a hinge with the frame, since the frame is fixed to the closure, further damage to the closure is avoided for the installation of the device. , because it is not necessary to make a drawer in the enclosure itself.
    [0062] Another object of the present invention is a door for livestock facilities characterized in that it comprises at least one closing device.
    [0064] Preferably the door will comprise at least two closing devices, each closing device being fixed on opposite edges of the door, so that in case of opening the door one of these devices acts as a hinge or to enable the complete removal of the door from the door. the enclosures.

    [0074] Figure 4 shows a perspective view of a door for livestock enclosures comprising a closing device according to an embodiment of the invention.
    [0075] Detailed description of the invention
    [0077] The present invention comprises a closing device (3) for doors (1) of livestock enclosures, said device (3) comprising means that prevent livestock present inside the livestock enclosure, especially pigs, from being able to open the door ( 1) and can escape from the enclosure.
    [0079] As can be seen in figure 1, the closing device (3) comprises a casing (10) for fixing it to an edge, or external frame, of a door (1). Said fixing of the casing (10) to the door (1) is easily appreciated in figure 4.
    [0081] Said casing (10) is connectable to an enclosure (2) as a hinge, for the connection between the door (1) and the enclosure (2), said connection is separable by vertical displacement of the door (1), thus allowing the disconnection of the door (1) and the enclosure (2).
    [0083] Being arranged, as can be seen in figure 1, in the device (3) a handle (30) with a blocking stop (31), the blocking stop (31) being configured to retain a vertical movement of the door (1) when abutting against the enclosure (2) in a locking position of the handlebar, which prevents the door (1) from opening by vertical displacement.
    [0085] Preferably the locking stop (31) is integrally attached to the end of the handle (30) which acts as a pivot axis, in such a way that the locking stop (31) moves around the pivot axis of the handle (30) .
    [0087] Preferably the handle (30) is pivotally connected to the housing (10), the handle (30) and the locking stop (31) being movable between a locking position, as seen in Figure 2, and a unlocking position, as can be seen in figure 3, of the door (1).
    [0089] The closure device (3) also comprises, as can be seen in figure 1, a retainer (40) pivotally connected to the casing (10), the retainer (40) being configured to retain the pivoting of the handle (30) in the locking position of the closing device (3), this prevents the handle (30) from changing its locking position of the handle (30) while it is hooked to the retainer (40), preventing accidental opening of the the door (1).
    [0091] Preferably the retainer (40) is pivotally connected to the casing (10), such that, due to its own weight or a spring, it automatically moves to a retention position, said retainer retention position ( 40) can be seen in figure 2.
    [0093] Additionally, in the preferred embodiment, the locking stop (31) prevents the handle (30) from pivoting in a direction opposite to its locking position by abutting against the side face of the casing (10). Thus, when force is released on the handle (30), it automatically pivots, either by its own weight or by a spring, in the direction of its locking position, automatically engaging with the retainer (40).
    [0095] As can be seen in figure 1, preferably the retainer (40) is substantially flat, reducing the cost of manufacturing the retainer (40) and therefore the closure device (3).
    [0097] Preferably the retainer (40) comprises a pusher (41) for unlocking the retainer with the handle (30), so that by grasping the handle (30) in the locked position it is possible to move the retainer (40) easily, for example with the use of the thumb so that it stops blocking the pivot of the handle (30) using a single hand to open the door (1).
    [0099] Preferably, as can be seen in figure 1, the casing (10) has a projection (20) that projects externally with respect to a lateral face of the casing (10), for the connection of the casing (10) to the closure (2) by tongue and groove.
    [0101] In the preferred embodiment of the invention, the projection (20) comprises, on one of its faces, a bolt (21) that projects vertically from said face.
    [0103] Additionally, the bolt (21) preferably has a cylindrical shape, which allows it to act as a hinge axis, in the event that, for various reasons, it is decided to open the door (1) from the end opposite the device.
    [0105] Preferably the handle (30) is angled at an end opposite the locking stop (31), in such a way as to facilitate the grip of the handle (30).
    [0107] Preferably, the casing (10) comprises a handle groove (11), as can be seen in Figure 1, for guiding the angled end of the handle (30). Said handle slot (11) also has a handle stop (12) at the end of the handle slot (11), allowing the handle (11) not to move automatically beyond its locking position.
    [0109] Furthermore, preferably the housing (10) comprises a retainer groove (13) that serves as a guide for the pivotal movement of the retainer (40) by means of a guide, incorporated in the retainer (40), configured to be insertable in the groove. retainer (13).
    [0111] The retainer groove (13) is comprised at its lower end by a retainer stop (14) that prevents the retainer (40) from automatically moving beyond its engagement position with the handle (30).
    [0113] Preferably the closing device (3) comprises a frame (5), as can be seen in figure 4, fixable to the enclosure (3), said frame (5) comprises a drawer unit (6) with means for connection between the door (1) and frame (5).
    [0115] In the preferred example of the invention, the connection of the casing (10) to the drawer unit (6) is made by means of the bolt (21), said bolt (21) is inserted vertically into the lower part of the drawer unit (6 ), preventing the horizontal movement of the door (1).
    [0117] Preferably, when the device (3) is in the locking position, as seen in figure 3, the locking stop (31) is parallel to the projection (20), so that the locking stop (31) It prevents the vertical movement of the door (1) when it collides with the upper section of the drawer unit (6).
    [0119] In said locking position, the retaining element (40) is hooked to the handle (30), preventing the pivoting of the handle (30), in this way the locking stop (31) remains immobile in a horizontal position.
    [0121] When the device (3) is in the unlock position, as can be Observe in figure 3, the locking stop (31) is parallel to the side face of the casing (10), in this way the surface of the locking stop (31) that can interfere with the vertical movement of the device (3 ) is minimal, allowing an easier disconnection between the drawer unit (6) and the closing device (3).
    [0123] Preferably, to make the disconnection between the closing device (3) and the drawer unit (6) the handle (30) is grasped, unhooking the retainer (40) pushing the pusher (41), thus unhooking the retainer (40) from the handle (30).
    [0125] The handle (30) is then pivoted until it is in a vertical position, as can be seen in figure 3, thereby achieving that the locking stop (31) is in a position parallel to the side face of the casing (10 ), allowing the release between the bolt (21) and the drawer (6).
    [0127] Once the closure device (3) is disconnected from the drawer unit (6), the handle (30) is released, in this way the handle (30) moves automatically, either by its own weight or by a spring, to the locked position, engaging with the retainer (40).
    [0129] To replace the closing device (3) in the drawer unit (6), the opposite process is carried out, first the retainer (40) is disengaged from the handle (30), then the handle (30) is pivoted until it reaches a vertical position, moment in which the bolt (21) is inserted inside the drawer (6), being able then to release the handle (30), which would automatically move to its locking position, hooking itself again with the retainer ( 40).
    [0131] In both cases, unhooking and hooking of the closing device (3) to the door (1), once it stops exerting a force on the pusher (41) the retainer (40) automatically moves to its retention position .
    [0133] Figure 4 shows a door (1) for livestock facilities which comprises two closing devices (3), according to the preferred embodiment, fixed to opposite edges of the door (1), said closing devices (3) being connected to the drawers (6) of the frames (5), securing the door (1) to the enclosures (2).
    [0134] Preferably the door (1) is additionally comprised of two hinges (4) fixed on opposite edges of the door, specifically on the same edges as the closing devices (3), these hinges (4) being connectable in drawers (6), said drawers (6) being different from the drawers (6) connected to the closing devices (3). This allows a more robust fastening of the door (1) to the enclosures (2).
