Description

Animal Shelter

BACKGROUND

a. Field of the Invention

This invention relates to a shelter structure or ark for a pig and more particularly to a farrowing ark or structure.

b. Related Art Most animals, including pigs or hogs, which may spend the majority of their time outside require shelter from the elements. They require a shelter from the wind and rain, and somewhere dry to rest, but they also require a shelter than can provide shade when it is sunny, a warm enclosure when it is cold and a cool place when it is hot.

Considering pigs or hogs in particular a number of shelters or housing structures are known that can accommodate one or more animals. A common type of shelter, especially in the United Kingdom, is a pig ark. Traditionally a pig ark has a semi-cylindrical shape and includes a continuously curved sheet forming the side walls and roof of the structure, and two generally semi-circular panels forming front and rear walls of the ark. At least one of the front and rear walls will include an opening providing an entrance/exit of the ark. A typical semi-cylindrical ark is illustrated in Figure 1. Another traditional shape of ark is illustrated in Figure 2.

An ark generally provides shelter for up to three or four pigs, depending on their size. One particular type of ark is a farrowing ark which is designed to house a sow and her litter.

Of particular consideration in the design of a farrowing ark is the problem of overlaying of a newborn piglet by a mother sow. This may take the form of the -2 -mother sow laying directly on the piglet or trapping the piglet against a structure causing crushing or suffocation of the piglet.

In traditional arks this problem is mitigated to some degree by providing side walls that contact the ground at an angle of less than 90°. This provides an edge region of the ark which is large enough for a piglet but in which the mother sow cannot fit, thereby providing a safe area for the piglets. The problem with traditional arks, however, is that there is typically at least one wall, for example a rear wall, that contacts the ground at 90°.

It is an object of the present invention to provide an improved animal shelter and, in particular, an improved pig ark that overcomes problems with prior art shelters.

SUMMARY OF THE INVENTION

According to the present invention there is provided a shelter for a pig, the shelter comprising a main body defining an interior space of the shelter, the main body having a substantially circular footprint when the main body is placed on the ground, and the main body including a side wall portion and a roof portion, and a first opening providing access to an interior space of the main body.

An external surface of the shelter is preferably substantially hemispherical.

In some embodiments the main body comprises an internal skin and an external skin, the external skin being spaced apart from the internal skin. Preferably, in these embodiments the space between the internal and external skin is at least partially filled with a heat insulating material. This helps to keep the interior space of the shelter warmer in cold weather and cooler in hot weather.

The main body preferably comprises a plastics material. In some embodiments the main body of the shelter is formed by rotational moulding. -3 -

To provide ventilation to the shelter the main body preferably includes a second opening, a lower edge of said second opening being at a distance from a bottom edge of the side wall portion of the main body. A size of the second opening is preferably automatically varied based on the temperature of the interior space of the main body. In particular the size of the opening preferably increases as the temperature of the interior space of the shelter increases. The size of the second opening is preferably also such that a person can enter and exit the interior space of the shelter through said opening.

In preferred embodiments the shelter comprises a door that is moveable between a first position in which the door covers said first opening and a second position in which the door extends substantially horizontally above said first opening. The door may, therefore, provide a canopy extending outwards over the first opening.

The shelter may be used as a farrowing ark and as such the shelter preferably includes a fender extending around an area proximate the first opening on an exterior of the main body.

Preferably the fender is hingedly connected to the main body such that the fender can be lifted into a storage position when it is not required or when a user wishes to move the shelter.

Preferably the fender comprises a curved side wall which maximises the usable area within the fender.

The fender may include a creep feeder. Alternatively or additionally the fender may comprise a water tank.

In preferred embodiments a diameter of a bottom edge of the main body is between 1.5 m and 2.6 m. More preferably a diameter of a bottom edge of the main body is between 2.0 m and 2.5 m. -4 -

DETAILED DESCRIPTION

A first embodiment of a shelter 1 for a pig according to the present invention is illustrated in Figures 3 to 8. Although the shelter 1 has been designed, in this embodiment, to house one or more pigs, it will be appreciated that the shelter may also or alternatively be used to house other animals by forming a shelter having

suitable dimensions.

The shelter 1 comprises a main body 2 defining an interior space of the shelter. The main body 2 is substantially hemi-spherical and has a substantially circular footprint when placed on the ground in use. Internal and external surfaces of the main body 2 are preferably substantially continuously curved and the internal surfaces define a substantially hemi-spherical interior space. In this embodiment the main body 2 comprises integral and continuous side wall and roof portions 4, 6. The side wall portion 4 terminates at a lower edge 8 of the main body 2 that, in use, is placed in contact with the ground. Importantly, the internal shape of the main body 2 is such that there are no flat surfaces against which young animals, such as piglets, can get trapped when an adult animal, such as a sow, lies down.

In this embodiment a lower edge region 9 of the side wall portion 4 adjacent the lower edge 8 has a greater thickness than the rest of the side wall portion 4. The lower edge region 9 defines a foot portion 9 of the main body 2 that projects radially outwardly. In this way, a shoulder or ledge 11 is defined in an outer surface of the main body at the transition between the foot portion 9 and the rest of the side wall portion 4 above.

The main body 2 preferably comprises an internal wall or skin and an external wall or skin. The external skin is spaced apart from the internal skin so as to define a cavity therebetween. This double-skin construction provides heat insulation such -6 -that the interior space of the shelter 1 remains relatively cooler in summer and relatively warmer in winter compared to a shelter having a single wall construction. In preferred embodiments the cavity between the internal and external skins is at least partially filled with a suitable heat insulating material, for example a heat insulating foam material. The overall thickness of the double-skin wall is preferably about 5 cm.

A shelf, recess or other receptacle may be secured to or formed in the internal wall of the main body 2. This shelf or recess may be sized to hold medicines, a clipboard, a record book or other items required by a farmer in the care of the animals. It is important that this shelf or recess is formed proximate the roof portion 6 of the main body 2, and most preferably above the height of an animal using the shelter 1. This allows the internal surface of the lower half of the main body 2 to be formed without any ledges, recesses or protrusions which means that at least this part of the shelter 1 is easy to keep clean as there are no features on or in which dirt could get trapped.

A first opening 10 is formed in the main body and provides an entrance and exit of the interior space. The opening 10 extends from the lower edge 8 of the main body 2 towards the roof portion 6 or apex 12 of the main body 2. The opening 10 will typically not extend for the full height of the main body 2 and in preferred embodiments the height of the opening 10 will be between 70% and 90% of the height of the main body 2 between the lower edge 8 and the apex 12. In this example the opening 10 is substantially trapezoidal and the base of the opening 10 is wider than a top edge of the opening 10.

Because the external surface of the main body 2 is curved, in order to provide a planar edge to the opening 10 that may be easily closed by a door 14, panels 16, 18 are provided that project outwards from the external surface of the main body 2 to form a porch region or passageway 20 of the shelter 1. In this embodiment two side panels 16 extend substantially vertically from the main body 2 and each side panel has a curved rear edge 22 in contact with the external surface of the main -7 -body 2 and a planar front edge 24 that forms a side edge of a doorway 26. It will be appreciated that the use of the term substantially vertical does not mean that the side panel 16 must be perpendicular to the lower edge 8 of the main body 2, but rather means that the side panels 16 extend generally upwards from the lower edge 8 of the main body 2 towards the apex 12 of the main body 2. The angle between a side panel 16 and the lower edge 8 of the main body 2 may be any angle between 45° and 90°. Similarly, a roof panel 18 extends substantially horizontally from the main body 2 between the two side panels 16. The roof panel 18 has a curved rear edge 28 in contact with the external surface of the main body 2 and a planar front edge 30 that forms a top edge 30 of the doorway 26. In this way, the side panels 16 and roof panel 18 form a passageway between the doorway 26 and the opening 10 in the main body 2.

The door 14 is hingedly or rotatably connected to the side panels 16 such that the door 14 can be moved between a first position in which the door 14 covers the doorway 26 and a second position in which the door 14 does not cover the doorway. In this example the connection is provided proximate a top edge 32 of the door 14 and is configured such that the door 14 is rotatable between the first position in which the door 14 is substantially vertical and the second position in which the door 14 is substantially horizontal and is located above the doorway 26. In this second position the door 14 extends in a direction away from the main body 2 such that a lower edge 34 of the door 14 is further from the main body 2 than the top edge 32 of the door 14. In this position the door 14, therefore, provides an additional canopy under which, in use, an animal may stand or lie with the door 14 providing shelter from the sun or rain. In preferred embodiments, when the door 14 is in its second position, the lower edge 34 of the door 14 is higher than the top edge 32 of the door 14. In this way, rainwater landing on the door 14 will tend to run in a direction away from the lower edge 34 of the door 14 and towards the main body 2 of the shelter 1.

Means may be provided to lock or secure the door 14 in the second, open position. These means may comprise a latch mechanism such as an auto gate -8 -latch. The door 14 preferably includes a window or aperture 31 proximate the top edge 32 of the door 14.

Means are preferably also provided to latch or secure the door 14 in the first, 5 closed position. These means may comprise an anti loose fastener.

Although in this embodiment the door 14 is hingedly connected to the side panels 16, in other embodiments the door 14 may be hingedly connected to the roof panel 18 or to the main body 2 of the shelter 1. In further embodiments the door 14 may be connected to the side panels 16, roof panel 18 or main body 2 in any suitable way to enable the door 14 to move between the first and second positions.

The door 14 may also be fully removable from the shelter 1, and the connection between the door 14 and the main body 2 or passageway 20 may be such that the 15 door 14 can be repeatedly removed from and attached to the shelter 1.

The main body 2 of the shelter 1 further comprises a second opening or vent 36. In this embodiment this second opening 36 is on an opposite side of the main body 2 to the first opening or doorway 26.

The second opening 36 is located in an upper region of the main body 2 so that there is a pad of the side wall portion 4 between the lower edge 8 of the main body 2 and a lower edge 38 of the opening 36.

A cover panel 40 is hingedly connected to the main body 2 proximate a top edge 42 of the second opening 36. The cover panel 40 is movable between a first, fully closed position in which the cover panel 40 fully covers and closes the second opening 36 and a second, fully open position in which at least a lower edge region of the cover panel 40 is at a distance from the main body 2 such that the second opening 36 provides ventilation to the interior space of the shelter 1.

Preferably, the cover panel 40 extends substantially horizontally from the main -9 -body 2 when the cover panel 40 is in its fully open position. Furthermore, it is beneficial if the dimensions of the cover panel 40 and the location of its connection to the main body 2 are such that, when the cover panel 40 is in the fully open position, the lower edge 44 of the cover panel 40 is positioned radially outwardly of the lower edge 38 of the second opening 36 when viewed from above. In this way, the cover panel 40 provides a canopy over the second opening 36 that minimises the amount of rain or sunlight that enters the interior space of the shelter 1 while still allowing ventilation of that space.

A frame 46 may be provided around the edges of the second opening 36 to provide a flat or planar surface on which the cover panel 40 is seated when in the closed position. In some embodiments, means may be provided to latch the cover panel 40 in one or both of the fully open or fully closed positions.

In preferred embodiments means are provided to automatically vary the extent of opening of the cover panel 40, and therefore the effective size of the second opening 36, depending on the temperature of the interior space of the shelter 1. In particular, the means are configured to increase the extent of opening as the interior temperature increases and decrease the extent of opening as the interior temperature decreases. Preferably a lower threshold temperature is set, below which the cover 40 remains in the fully closed position.

The means to automatically vary the extent of opening of the cover panel 40 may comprise a piston or ram connected between a part of the main body 2 or frame 46 and the cover panel 40. A temperature sensor within the interior space of the shelter 1 and appropriate circuitry may be provided to control the operation of the piston or ram to open and close the cover panel 40. In preferred embodiments the means to automatically vary the extent of opening of the cover panel 40 comprises a thermal actuator. The thermal actuator may be a wax actuator. The wax actuator, or other thermal actuator, may be located within the cover panel 40, or within a part of the main body 2 or frame 46, so as to minimise the likelihood of damage occurring to the actuator.

-10 -In other embodiments of the shelter the effective size of the second opening 36 may be varied by other means. For example rotatable vanes may extend across the opening 36 or a screen may be provided that slides between a fully open and a fully closed position.

The dimensions of the second opening 36 are preferably such that a person can exit the interior space of the shelter 1 through the second opening 36 should exit through the first opening be prevented. To this end, recesses for a person's hands or feet may be provided to enable them to safely climb up to and descend from the second opening 36.

In the embodiment illustrated in Figures 3 to 8 the shelter 1 is in the form of a farrowing ark. The shelter 1, therefore, further comprises a fender 50 that surrounds an area immediately adjacent and external to the doorway 26. The fender 50 includes a side wall 52 that in this example is curved so as to form a boundary around a substantially D-shaped area.

The side wall 52 of the fender 50 is continuous and terminates at first and second ends 54 that are connected to the main body 2 of the shelter 1 on respective sides of the doorway 26. The side wall 52 preferably has a substantially S-shaped cross-sectional shape or stepped profile, which is shown most clearly in Figure 7. Accordingly, the side wall 52 has a lower portion 51 and an upper portion 53, and the upper portion 53 is located radially inwardly of the lower portion 51. In this way, a step or ledge 55 is defined in the outer surface 57 of the side wall 52 at the transition between the lower and upper portions 51, 53.

In some embodiments the fender 50 may comprise a creep feeder (not shown). The creep feeder may be of any suitable design. The fender 50 may also include 30 a water tank (not shown) to provide a water supply to animals housed in the shelter 1.

Typically a fender is only required for about the first two weeks after farrowing and, accordingly, it is then necessary to remove the fender. To avoid having to fully remove the fender 50 and store this elsewhere, the fender 50 of the present invention is preferably hingedly connected to the main body 2 of the shelter 1 at its ends 54. Connecting the fender 50 to the main body 2 in this way also means that it is easier to move the main body 2 and the fender 50 together as a single unit.

The connection is configured such that the fender 50 can be lifted so that fender 50 is substantially vertical and surrounds the doorway 26 of the shelter 1.

Accordingly, the dimensions of the fender 50 are such that a front region 56 of the fender 50, furthest from its ends 54, locates above the top edge 30 of the doorway 26 when the fender 50 is lifted into its storage position. Means may be provided to lock or latch the fender 50 in this storage position when it is not required. Additionally, means may be provided to latch the fender 50 in its lowered position in use.

In preferred embodiments the fender 50 is connected to the side panels 16 extending from the main body 2. A rod or bar 58 protrudes outwardly from each of the side panels 16. A cross-sectional shape of the rod 58 is elongate, for example rectangular as shown in Figure 9, and has a longer dimension and a shorter dimension. Each end 54 of the fender 50 includes a slot 60 for receiving the rod 58 formed in an inner surface 62 of the fender 50. The slot 60 includes a first portion 64 and a second portion 66. The first portion 64 extends between an end surface 68 of the fender 50 and the second portion 66. The first portion 64 has a generally rectangular cross-sectional shape and a width of the first portion 64 in a direction parallel to the height dimension of the fender 50 is greater that the length of the shorter dimension of the rod 58 and smaller than the length of the longer dimension of the rod 58. In this way the rod 58 may only be inserted through the first portion 64 of the slot 58 with the fender 50 held in a narrow angular range with respect to the main body 2. The second portion 66 of the slot 60 has a generally circular cross-sectional shape in a plane parallel to the height dimension of the fender 50. The diameter of the second portion is greater than the length of the -12 -longer dimension of the rod 58.

In this way, the fender 50 is connected to the main body 2 by holding the fender 50 at the required angle such that the rod 58 can be inserted through the first portion 64 of the slot 58 and into the second portion 66. The fender 50 can then be rotated such that the fender 50 is located on the ground or in its storage position described above. In each of these positions the orientation of the rod 58 is such that it cannot pass through the first portion 64 of the slot 58 and the fender 50 is, therefore, connected to the main body 2. To detach the fender 50 from the main body 2 the fender 50 is lifted and rotated relative to the main body 2 about the rod, until the slot 58 and the rod 58 are in alignment such that the rod can pass through the first portion 64 of the slot 58 and the fender 50 can be pulled away from the main body 2 of the shelter 1.

The main body 2 of the shelter 1 is preferably made from a suitable rigid plastics material, and is preferably formed by rotational moulding. In some embodiments the side wall and roof portions 4, 6 of the main body 2 are made of a translucent plastics material. This allows some light to pass through the main body 2 and provide some illumination of the interior space of the shelter 1. The other components of the shelter 1, such as the cover panel 40, side wall panels 16, roof panel 18, door 14 and fender 50 are preferably also made of a suitable plastics material.

The external diameter of the main body 2 at the lower edge 8 is preferably between 1.5 m and 2.6 m, and more preferably between 2.0 m and 2.5 m. A height of the main body 2, between the lower edge 8 and the apex 12, is preferably between 1.0 m and 1.5 m, and more preferably between 1.1 m and 1.3 m.

The shelter 1 of the present invention has a number of advantages over prior art ark designs. In particular, the shape of both the main body 2 and the fender 50 allows these to be stacked for ease of transport and storage. In the embodiment -13 -illustrated in Figures 3 to 8 the main body 2 of the shelter 1 can be stacked such that the lower edge 8 of one shelter 1 is seated on the shoulder 11 of another shelter 1. Furthermore, the stepped profile of the fender 50 is such that the lower portion 51 of one fender 50 can be seated on the ledge 55 of another fender 50.

Each shelter 1 is preferably provided with the lifting loop 70 attached to the roof portion 6 of the main body 2, as shown in Figure 8. The lifting loop 70 is preferably made from a flexible band or strip of material. The material may be rubber or a suitable woven material for example. The flexibility of the lifting loop 70 is such that the loop 70 can be squashed flat when two shelters 1 are stacked one on top of the other, but can expand to a substantially circular shape to accept a part of a lifting means therethrough when a user wishes to move the shelter 1. The lifting means may include, for example, a tine of a fork lift or a hook. The position of the lifting loop 70 relative to the apex 12 of the main body 2 is such that the lower edge 8 of the main body 2 remains substantially horizontal when the shelter 1 is lifted above the ground, even if a fender 50 is attached to the main body 2 in its storage position as shown in Figure 8.

Figure 10 shows a further embodiment of a shelter 101, and in particular shows the configuration of a second opening 136 and cover panel 140 in an upper region of a main body 102 of the shelter 101. In this embodiment, the cover panel 140 is connected by means of a hinge 141 to a top panel of a frame 146 surrounding the second opening 136.

Figure 11 shows another embodiment of a shelter 201 according to the present invention. In this embodiment the door 214 comprises a plurality of panels configured such that, when the door 214 is in its second position, the angular configuration of the panels is such that rainwater landing on the door 214 is directed towards a central region of the door 214 and more particularly towards an aperture 231 in an upper region of the door 214 proximate a top edge 232.

The rainwater will then tend to drain through this aperture 232 and into a gully or -14 -channel 272 provided in an upwardly facing surface of a roof panel 218 above the doorway 226. Suitable guide features 274, 276 are provided in side panels 216 and in foot portion 209 of the main body 202 so that the rainwater flows from the channel 272 down the either side of the doorway 226 and to the ground. The guide features 274, 276 may be in the form of channels, grooves or ridges.

Importantly this arrangement of the door 214, channel 272 and guide features 274, 276 means that rainwater is directed away from the area of ground immediately outside the doorway 226, thereby keeping the area of ground within the fender 50 relatively dry.

In this embodiment the shelter 201 also includes a beam 278 positioned proximate the lower edge 208 of the main body 2 and extending across the doorway 226. In use, a bed or layer of straw is typically laid over the ground in the interior space of the shelter 1. The beam 278 prevents or reduces the amount of straw being dragged out of the interior space by the pigs or other animals resident in the shelter 1. The beam 278 may be of any suitable type and of any suitable dimensions to fulfil this function.

In some embodiments of the shelter 1 of the invention in which the main body 2, 102, 202 is of double-skin construction, the interior space between the external and internal skins in a lower edge region of the main body 2, 102, 202 may be filled with water or sand. This has the advantage of adding extra weight to the main body 2 to avoid it being blown around in strong winds. The hemi-spherical shape of the external surface of the main body 2 also means that the shelter 1 is more aerodynamic than traditional arks irrespective of the direction of the wind.

Additionally, if the lower edge region of the main body 2, 102, 202 is filled with water, this water may act as a heat sink helping to keep the interior of the shelter 1 cooler in hot weather or during the day and warmer in cooler weather or during the night. The water stored in the walls of the main body 2 may also be used to provide drinking water for the sow or other adult animal housed in the shelter. At least a lower portion of the fender 50 may also be designed to be able to be filled -15 -with water. This water in the fender 50 may be used to provide drinking water for piglets or other young animals, and the water may be provided via, for example, a nipple drinker.

Although in the above description features have been described in relation to different embodiments of the invention, it will be appreciated that these features may be combined in a single embodiment.

The present invention, therefore, provides an improved animal shelter or pig ark

that overcomes problems with prior art shelters.
