IMPROVED DOOR SYSTEM FOR A CONTAINER CORRIDOR AND

CONTAINER HALL COMPRISING THE SAME

The present invention relates to the field of livestock equipment.

The present invention relates in particular to an improved door system for an animal restraint corridor, in particular for an adjustable width type restraint corridor, and to such an animal restraint corridor equipped with this.

Contention corridors are used in the field of breeding, in particular cattle breeding, for the handling of animals, in particular with a view to applying a treatment to each animal on a breeding farm.

The containment corridors are formed, in a known manner, by a set of beams and crosspieces between which sheets can be placed and forming a rectangular base cage whose width, namely the width of the passage of animals, must correspond to that animals to be treated.

The application of a treatment to each animal requires that the width of the passage of animals is sufficiently narrow so that two animals cannot simultaneously engage in this passage and to prevent the animal from turning over.

Since the animals to be treated may be small animals, such as calves, or larger animals, such as cows, it is necessary that the width of the passage of animals is adjustable.

Thus, it is known to use a compression corridor of adjustable width type, the spacing between the side walls of which is adjustable according to the size of the animals to be treated, such as for example the compression corridor disclosed in patent FR2577381.

Such containment corridors include a central sorting door or gate system. This system includes a side door capable of opening by pivoting about a vertical axis, towards the inside of the corridor, to allow a breeder to access the interior of the corridor, and to place himself behind an immobilized animal. in the corridor, the following animals are blocked by the door closing the passage of animals.

In the case where the width of the corridor is adjustable, this door or gate system must be mounted movable relative to the walls of the corridor so as to adapt to different widths of passage of animals. Indeed, a conventional side door pivotally mounted relative to the walls of the compression corridor could not be placed transversely to the passage of animals in the case where the width of the passage is less than the maximum width thereof and therefore at the door width.

Thus, it is known to equip the contention lanes with adjustable width with a central gate system in translation. In this translation system, the gate, whose width corresponds to the maximum width of the passage of animals, is mounted movable in translation along a direction transverse to said passage of animals.

Such a translational door system has drawbacks. Indeed, when the passage of animals is open, the door projects outside the cage forming the corridor. The door then constitutes an obstacle for the movement of the breeder along the corridor. In addition, this translational door system only allows the corridor to be separated into two, and must be associated with a side door pivotally mounted around a vertical axis and allowing access to the breeder inside the corridor.

The present invention aims to propose a solution to remedy the above drawbacks by proposing a central gate system which can be adapted in a simple and practical manner to a passage of animals of variable width while allowing a breeder to access inside the corridor and stand behind an animal immobilized in the corridor.

The present invention therefore relates to a door system intended to be mounted on an animal restraint corridor, which restraint corridor comprises a frame forming a cage having two side walls delimiting an animal passage, the door system being intended to be mounted in a lateral opening that comprises at least one of said side walls, the door system comprising a first so-called rotating part comprising connecting means for connecting the door system to said side wall in a rotary manner around a vertical axis fixed with respect to the frame, characterized in that the door system further comprises a so-called sliding part, mounted movable in horizontal translation relative to the rotating part and supported by it, so that the width of the door system is adjustable by translational movement of the sliding part relative to the rotating part.

Preferably, the rotating part and the sliding part are offset with respect to each other in the direction perpendicular to the vertical plane containing the direction of translation of the sliding part and the sliding part is capable of sliding in front of the rotating part and beyond the latter.

Preferably, the sliding part is in the form of a panel assembly of generally rectangular shape and is movable in translation between two end-of-travel positions, namely a first position in which said connecting means that the rotary part comprises located behind the region of a vertical edge of said panel assembly, the opposite vertical edge of said panel assembly being thus at a distance from said connecting means, and a second position in which said panel assembly has slid in the direction from said first to said second vertical edge . The expression “panel assembly” is understood here to mean a generally planar structure, whether it is constituted by a panel as such or a plate as such, or for example by a mechanically welded frame closed or not by one or more sheets, with or without the presence of intermediate sleepers.

In the above configuration, the sliding part effectively forms the opening of the door system, and thus the width of the door system is equal to that of the sliding part. The rotating part is concealed behind the sliding part and therefore does not fulfill the function of closing the lateral opening of the compression corridor or the passage of animals, which function is only ensured by the sliding part. This configuration is also advantageous in that it makes it possible to provide movable shutters in the sliding part for easier access to the animal by the breeder over the entire width of the corridor, without hindrance by the rotating part.

Preferably, one of the rotating part and of the sliding part comprises at least one slide while the other of the rotating part and of the sliding part comprises rolling or sliding means mounted so as to be able to roll. or slide on the at least one slide. Preferably, the rolling means are carried by the rotating part and comprise a first pair of upper grooved wheels and a second pair of lower grooved wheels, vertically from one another, the grooved wheels being mounted freely rotatable around a horizontal axis perpendicular to the direction of translation of the sliding part, each pair of grooved wheels being mounted on a respective slide carried by the sliding part and comprising a straight edge received in the grooves of grooved wheels.

Preferably, the door system according to the present invention further comprises elastic biasing means of the sliding part in the direction tending to increase the width of the door system, the elastic biasing means being interposed between the rotating part and the part sliding. These elastic biasing means will, for example, be a simple spring, in particular a tension spring, but a cylinder could be provided instead.

According to a particular embodiment, the rotating part comprises a vertical bar provided, at at least one end, with said connecting means for connecting the door system to said side wall in a rotatable manner around a vertical axis fixed relative to the chassis , as well as two crosspieces spaced vertically one above the other and a so-called inner cover extending between the two crosspieces so as to delimit part of an interior space with the sliding part which it comprises a rectangular frame formed of two uprights connected by two crosspieces, a so-called external cover extending between said uprights and said crosspieces of the sliding part and closing said internal space, if necessary at least one slide and the rolling or sliding means, as well as the elastic biasing means, being housed in said interior space.

Preferably, the sliding part carries at least one handle, preferably two handles, including a horizontal handle and a vertical handle.

Preferably, the sliding part carries locking means in position at its free end, called the locking end, which locking means being able to be received in a first housing of the compression corridor when the door system closes said lateral opening and in a second housing of the compression corridor, provided in the side wall opposite to that comprising said lateral opening, when the door system closes said animal passage, the locking means preferably comprising at least one caster mounted freely rotating around a vertical axis. One could just as easily provide a pair of such rollers arranged one above the other.

The present invention also relates to an animal restraint corridor comprising a frame forming a cage having two side walls delimiting a passage for animals, at least one of the side walls being movable so as to allow the width of the passage to be adjusted. animals, the containment corridor comprising at least one door system mounted in a lateral opening that comprises at least one of said side walls, characterized in that the door system is as defined above, the part revolving being rotatably mounted about a vertical axis and being able to move between an animal passage opening position, in which the door system closes said lateral opening, and an animal passage closing position , in which the door system extends transversely to the passage of animals and leaves free access through the lateral opening, the movement of the door system between said two positions being obtained enu by a combined movement of rotation of the door system around said vertical axis and translation of the sliding part relative to the rotating part.

When the animal restraint corridor comprises at least one door system provided with locking means, the amount of the lateral opening opposite the amount to which the rotating part is rotatably connected and the side wall of the corridor opposite to the side wall comprising the side opening each advantageously comprise a vertical groove forming a housing capable of receiving the locking means of the door system.

To better illustrate the object of the present invention, a preferred embodiment will be described below, by way of illustration and without limitation, with reference to the attached drawing.

On this drawing :

- Figure 4 is a vertical cross-sectional view, along the plane A-A, of the door system of Figures 2 and;

- Figure 5 is a perspective view of the animal restraint corridor of Figure 1, showing the door system in the unlocked position of the side opening;

- Figure 6 is a perspective view from above of the animal restraint corridor of Figure 1, the width of which is maximum, with the door system in the closed position for the passage of animals;

- Figure 7 is a top view of the animal restraint corridor, the width of which is adjusted to a value less than the maximum width, the door system being halfway towards the closed position for the passage of animals ; and - Figure 8 is a perspective view from above of the animal restraint corridor of Figure 7, the door system being in the closed position of the animal passage.

If one refers to Figure 1, one can see that the door system 1 according to the present invention is intended to equip an animal restraint corridor 2, in particular an adjustable width corridor.

It should be noted that the door system 1 according to the present invention can be fitted to both a fixed and mobile compression corridor, and also a corridor with fixed walls, with a mobile wall or with two mobile walls.

Such a door system 1, because of its simultaneous pivoting and sliding capacity, is particularly suitable for being used as a central sorting door, the role of which is to allow a breeder to access the interior of the lane 2 and stand behind an animal immobilized in lane 2 while blocking the passage of the following animals.

If one refers to Figures 1 and 5 to 9, it can be seen that the door system 1 is mounted in an animal restraint corridor of adjustable width type 2. Such a restraint corridor 2 has a frame in shape of parallelepiped cage, delimited by two side walls generally designated by the reference number

3, a front part 4 and a rear part 5. The compression corridor 2 shown in FIG. 1 is a movable corridor carried by a pair of wheels R.

At least one of the two side walls 3 has a lateral opening 6 (visible in FIGS. 7 and 8) delimited by a left lateral upright 7 and a right lateral upright 8 extending vertically.

This lateral opening 6 is equipped with the door system 1, which is shown alone in Figures 2 to

4.

As can be seen in these Figures, the door system 1 comprises two movable parts, namely a rotating part 9 and a sliding part 10.

The rotating part 9 comprises a vertical bar 11 provided at its lower end with a pivot 12 destinéο intended to be received in a pivot housing provided for this purpose on the chassis of the compression corridor 2, the upper end of the vertical bar 11 being configured to cooperate with a pivot with a vertical axis also provided for this purpose on said chassis. Thus, the rotating part 9 is rotatably connected to said chassis so as to be able to pivot around a vertical axis. In particular, the vertical bar 11 is located in the plane of the lateral opening 6 and next to the left lateral upright 7.

An upper cross member 13 and a lower cross member 14 both extend horizontally from the same side of the vertical bar 11, in the vertical plane of the door system 1. The cross members 13 and 14 have a first length.

At each of the end regions of the crosspieces 13, 14 is mounted a grooved wheel 15 which can rotate freely around a horizontal axis perpendicular to the longitudinal axis of the crosspieces 13, 14. This mounting can for example be carried out by joining one end of a pivot 16 to the cross member 13, 14 and mounting a grooved wheel 15 with free rotation around the pivot 16.

A sheet metal cover 17 extends between the external vertical faces of the crosspieces 13, 14, over the entire length of the crosspieces 13, 14, and comprises a free vertical edge back towards the inside over a distance corresponding overall to the width of the sleepers 13, 14

As can be seen in Figures 3 and 4, a first tab 18 extends downward from the upper cross member 13, away from the vertical bar

11, and a second tab 19 extends laterally from the vertical bar 11, in the direction of said first π

tab 18. A tension spring 20 (shown very diagrammatically by a rectangle) is mounted between the first and second tabs 18, 19, and is thus located in front of the cover 17.

The sliding part 10 comprises a frame mounted in front of the rotating part 9 and delimited by first and second uprights 21 and 22 connected by upper and lower crosspieces 23, 24. The first upright 21 is slightly shorter than the vertical bar 11, and the second upright 22 is here shorter, but of sufficient size for said frame to completely cover the rotating part 9. A sheet metal cover 25 is fixed to said frame and extends between said uprights 21, 22 and said crosspieces 23, 24, thus defining with the cover 17 an interior space in which the grooved wheels 15 and the spring 20 extend.

In the upper part of the cover 25 is fixed a vertical plate forming a rail 26, the rail 26 extending downward from a recess of the cover 25 towards the outside and the free lower edge of the rail 26 being received in the grooves grooved wheels 15 carried by the upper cross member 13 of the rotating part 9. Similarly, a vertical plate forming a rail 27 is fixed in the lower part of the cover 25 and extends upwards from a recess of the cover 25 outwards, so that the free upper edge of the rail 27 is received in the grooves of the grooved wheels 15 carried by the lower cross member 14.

It is thus easily understood that the rails 26, 27 act as a slide whose displacement in horizontal translation will be guided by the grooved wheels 15.

It is emphasized here that the sliding part 10 is dimensioned to be the same width as the lateral opening 6, and that the cross members 23, 24 of the sliding part 10 are longer than the cross members 13 and 14 of the rotating part 9. By this configuration, together with the fact that the sliding part 10 is located in front of the rotating part 9, the sliding part 10 can be moved in translation, in the direction going from the free end of the crosspieces 13, 14 towards the vertical bar 11, at beyond the longitudinal axis of the vertical bar 11. In other words, if one refers to Figure 3, showing the door system 1 in the closed position of the side opening 6, the part sliding 10 can be moved in translation to the right. A translation in this direction will lead to a traction of the spring 20, which will thus bring the sliding part 10 back to the position shown in FIG. 3 when the sliding part 10 is released. The translational stops of the sliding part 10 are formed by the first and second uprights 21, 22, against which the grooved wheels 15 will abut.

Furthermore, the sliding part 10 further comprises two handles on its outer side, including a vertical handle 28 and a horizontal handle 29. The vertical handle 28 extends along the first upright 21, in the upper part thereof. The horizontal handle 29 extends along the upper cross member 23, in the vicinity of the second upright 22. These two handles 28, 29 allow a breeder to easily manipulate the sliding part 10 by a combined sliding movement, using of the vertical handle 28, and of rotation, using the horizontal handle 29.

The sliding part 10 also carries locking means 30 of the door system 1, intended to cooperate with complementary means provided in the walls of the compression corridor. These locking means 30 comprise two rollers 31 mounted for free rotation around vertical pivots (not visible) carried by the second upright 22 of the sliding part 10. The two vertical pivots, spaced apart from each other vertically, are thus extend parallel to the second upright 22 and are offset towards the outside of the latter. In other words, the two rollers 31 project from the outside of the sliding part 10.

The combination of the movements of the two movable parts 9, 10 of the door system 1, namely the pivoting movement of the rotating part 9 around a vertical axis and the movement of horizontal translation of the sliding part 10 relative to the part revolving 9, allows the door system 1 to be able to be moved both in rotation and in translation, simultaneously.

As can be seen more particularly in FIGS. 5 to 7, such movements make it possible to pass the door system 1 from a position for closing the lateral opening 6 to a position for accessing the lateral opening and closing the animal passage, what is the width adjustment of the animal passage.

If we refer first to Figure 5, we can see that the passage of the door system 1 from a locked position closing the side opening to an unlocked position is achieved by simply sliding the sliding part 10 opposite the right lateral upright 8.

In particular, in the initial locked position, the door system 1 extends across and closes the lateral opening 6, the sliding part 10 being pushed towards the right lateral upright 8 by the action of the spring 20 and the two casters 31 being engaged in a vertical groove forming a housing 32 formed along the right lateral upright 8. In order to unlock the door system 1 for pivoting towards the inside of the compression corridor 2, the breeder grasps the vertical handle 28 and pulls the sliding part 10 opposite the right lateral upright 8, against the action of the spring 20, until disengaging the rollers 31 with respect to the vertical groove 32, as shown in Figure 5.

The breeder can then rotate the entire door system 1, in order to pass the door system 1 from the unlocked position of Figure 5 to the closed position for the passage of animals. To pivot the entire door system 1 towards the inside of the corridor, by 90 degrees, the breeder grasps the horizontal handle 29 and causes the rotating part 9 to pivot from its vertical pivot axis, until the rollers 31 come into contact with the side wall 3 of the compression corridor 2 opposite to that comprising the lateral opening 6. This pivoting movement is thus accompanied by a simultaneous relaxation of the traction exerted on the vertical handle 28, so that the spring 20 slides the sliding part 10 in the opposite direction.

When the door system 1 has been turned by almost 90 °, the rollers 31 arrive near a vertical groove forming a housing 33 provided in the side wall 3 opposite the vertical bar 11. When the breeder continues the pivoting of the door system 1, the rollers 31 will engage in said housing 33 under the action of the spring 20, thus locking the door system 1 in the closed position for the passage of animals, as shown in FIG. 6.

In Figures 5 and 6, the width of the compression corridor 2 is set to the maximum width. The sliding part 10 is dimensioned so as to be able to close the passage of animals of maximum width and therefore has a width substantially equal to this maximum width.

As can be seen in Figures 7 and 8, in the case where the width of the compression corridor 2 is adjusted to a width less than the maximum width, therefore less than the width of the sliding part 10, when the door system 1 is brought into the closed position for the passage of animals, the rollers 21 will come into contact with the side wall 3 earlier, as shown in FIG. 7, and the sliding part 10 will thus be made to slide outwards and will protrude partially outside the compression corridor 2, as can be seen in Figure 8. Thus, in this position, the sliding part 10 is slid so as to cover the pivot axis of the rotating part 9 and to protrude beyond it by a distance corresponding to the difference between the maximum width and the adjusted width of the compression corridor 2. The action of the spring 20 nevertheless maintains the sliding part 10 in the locked position in the wall lateral 3 opposite the compression corridor 2.

Consequently, the sliding mounting of the sliding part 10 with respect to the rotating part 9 allows the door system 1 to be adapted in a compression corridor 2 having a variable width, in a simple, rapid manner, forming no obstacle for the breeder and guaranteeing the safety of the breeder during the treatment of an animal immobilized in the restraint corridor 2.

It is understood that the particular embodiment which has just been described has been given by way of non-limiting indication and that modifications can be made without departing from the scope of the present invention.
