Description

[0001] PET CARE BOOT

[0002] The present invention relates to a cryotherapy treatment boot for animals, preferably for equines.

[0003] The present invention further relates to a method of manufacturing a cryotherapy care boot for animals.

[0004] The present invention finally refers to a use of a cryotherapy treatment boot for animals.

[0005] Indeed, the present invention relates to a cryotherapy treatment boot for animals and more particularly for equines which include in particular horses, donkeys, mules, zebras.

[0006] It is well known that animals, and especially equines, especially horses, have a natural need to walk, which is essential to their general well-being and health. Indeed, for horses, the action of moving, walking or even running is more than just exercise but is also therapeutic. Indeed, when a horse moves, walks or runs, the hoof acts as a second blood pump to circulate blood to the extremities and return to the animal's heart. This allows the animal to have better general blood circulation, good blood circulation and oxygenation of all organs, contributing to its good health and general well-being.

[0007] Furthermore, equines are animals whose weight is generally several hundred kilograms and this weight is fully supported by the lower limbs, legs, feet / pasterns, hooves, which therefore need to be continuously exercised and trained to contribute to the good general health of the animal. In addition, to contribute to the good general health, equines and more particularly horses, donkeys or other zebras also need to be well treated, particularly in the prevention and anticipation of injuries and their healing and treatment if necessary. It is thus considered that the lower limbs of equines, such as legs, feet / pasterns, hooves, are extremely delicate parts of the animal and require great attention from their owner, caregivers, veterinarians.

[0008] Indeed, it is well known that injuries to the lower limbs of equines, horses, etc., can at best cause serious and certain discomfort and in the worst case be fatal for the animal. This is explained on the one hand because the lower limbs of equines are sensitive parts and difficult to treat in the event of injuries, cuts, infections, and on the other hand because when the animal is injured and feels discomfort in one or more of its lower limbs, it has more difficulty supporting its own weight and can generally no longer move properly, which can deteriorate its state of health very quickly.

[0009] Another risk factor is also the lack of exercise, for example horses or equines whose physical activity is insufficient, who do not walk, run, or leave their stalls enough, this generally leads to muscle loss in the lower limbs which have more difficulty supporting the animal's own weight, unfortunately leading to falls / collapses of the animal and subsequent injuries, which is neither recommended nor desirable.

[0010] It is therefore easy to understand that for animal owners, professional or occasional riders, veterinarians, animal care staff or even athletes, very particular care and attention must be observed regarding the well-being and general health of animals and more particularly regarding the proper functioning, condition and health of the lower limbs, in particular the legs, feet / pasterns, hooves of equines. This is made possible by the training and regular and continuous exercise of the animals, but also in the prevention of injuries and their care when unfortunately such injuries occur.

[0011] Cryotherapy or cold treatment is recognized as a beneficial and effective method for treating the lower limbs of equines, particularly horses, alone or in combination with other exercises or care provided to the animal. Cryotherapy is used in particular for the treatment of injuries, the treatment of muscular injuries, or for the rapid and effective recovery of the animal's muscles after training, a competition or simply for comfort to refresh the muscles after exercise. For this purpose, various methods and devices for cryotherapy treatment are known according to the state of the art.

[0012] First of all, there are "pools" for animals, equines, horses, which include a large quantity of iced water or cold water in which the animals move.

[0013] Unfortunately, although this solution exists, it turns out that it requires a lot of available space, a bulky and particularly heavy installation to be placed on the ground, as well as increased surveillance to prevent the animal from escaping.

[0014] An initial improvement consisted of more compact water and ice baths rather than large animal "pools," these baths resembling more barrels or containers. With such devices, the animal no longer moves freely, but one of its lower limbs is placed in the bath for more targeted treatment.

[0015] Unfortunately, and quite similarly to the previous solutions, water and ice baths such as barrels or containers are still bulky and are difficult to adapt to animals. It is indeed difficult to force such animals to remain motionless, in an often uncomfortable position, for a long period of time. This generally results in sudden and powerful movements on the part of the animal, which at best overturns the barrel of iced water, making this solution ineffective, and at worst can lead to risks of injury / further injury to the animal, or even to the person watching the animal.

[0016] A further improvement was the application of local cryotherapy solutions, for example by means of the targeted and local application of ice packs.

[0017] Unfortunately, such ice packs are difficult to stay in place, the sudden and powerful movements of animals and in particular equines, horses etc. can move, throw and damage the bag, resulting in the spillage of the liquid intended for cooling / refreshing, ice. In addition, it can happen that the ice packs are firmly attached using adhesives but the ice being wrapped in the bag, the friction and contact between the animal's limb and the cold is greatly limited, which makes this solution ineffective. This also requires intensive monitoring of the animal to replace or replace the ice pack each time it moves from its desired position, or is damaged.

[0018] Cryotherapy treatment boots for animals, and in particular for equines, have therefore been developed, which attempt to resolve these problems, for example comprising a sole, a waterproof or even leak-proof sleeve and a system for attaching to the animal's foot. The waterproof or even leak-proof sleeve has a first end connected to the sole, and a second open end to accommodate at least part of the animal's leg.

[0019] For this purpose, the state of the art includes document DE2604884, which discloses a treatment boot that includes a sole on which are fixed an inner covering and an outer covering that define a housing to accommodate the paw of an animal, and when the paw of the animal is inserted into the boot according to document DE2604884, a space between the inner covering and the outer covering will be filled with water and ice, the boot will then be closed by several strap systems, to tighten around the leg of the animal, the inner covering at the hoof, the inner covering at the leg, the outer covering at the hoof, the outer covering at the leg.

[0020] Furthermore, document US2021 / 0275350 is known, which discloses a reinforced flexible sock for cryotherapy treatment, comprising a sole with means for attachment to the animal's foot, connected to a vertical wall made of flexible material provided with a zipper and which defines a housing for receiving the animal's leg as well as a cooling liquid, fluid or solid.

[0021] Finally, document WO2018 / 200480 is known which relates to a wrap-around boot for cryotherapy treatment of the leg / paw of an animal, with a sole which comprises a first safety mechanism with a first plurality of straps and buckles allowing the sole to be correctly held against the hoof of the animal. The wrap-around boot further comprises an insulating sleeve with a zipper which allows a means of care of the animal to be held such as a hot or cold liquid, ice, medical baths etc., this sleeve being secured to the leg of the animal by a second plurality of straps and buckles. Unfortunately, although the solutions disclosed in the prior art above may have certain advantages from a theoretical point of view, it turns out that in reality they remain insufficient and would deserve to be improved in order to be able to ensure effective and reliable cryotherapy care over time.

[0022] Indeed, it turns out that such systems unfortunately require several installation manipulations, attaching several straps and buckles to the horse's leg and securing the entire device before they can be properly filled with a cooling liquid or solid, this causing a source of stress and discomfort for the horse which is not desirable, these animals being already very sensitive to external disturbances. In addition, such systems with attachments at the top of the equine's leg, the horse, fall off when the animal moves, it is therefore necessary to replace them frequently.

[0023] In addition, when the habits of animals, equines, horses are modified creating a source of stress and discomfort or when they are frightened, they can kick violently and / or hit the ground, which causes damage to the care boots or even their tearing.

[0024] Furthermore, the welfare and care of animals (equines) in the case of cryotherapy treatment, and more specifically for horses, is of growing interest. Horse owners, owners of equestrian centers, veterinarians and animal clinics, as well as athletes and riders, are looking for solutions and care boots that are easily adaptable to horses / equines, even intolerant ones.

[0025] There is therefore a real need to provide a cryotherapy treatment boot for animals that is easy and quick to install and remove, thus avoiding stressing the animals during installation, removal or use, that is easy to position and maintain, that is reliable in its effectiveness over time, in particular that is resistant and that remains in place even when an animal is frightened, stressed or makes violent movements.

[0026] The present invention aims to overcome the drawbacks of the state of the art by providing a cryotherapy treatment boot for animals, preferably for equines, as mentioned above, comprising a waterproof sleeve and a sole device which comprises a system for attachment to the animal's foot, the waterproof sleeve has a first end connected to the sole device, and a second open end to accommodate at least part of the animal's leg, characterized in that the waterproof sleeve is a self-supporting sleeve.

[0027] It has been found, in a particularly surprising manner, that it is possible to provide a boot according to the present invention which makes it possible to overcome the disadvantages of the state of the art, and this in a particularly synergistic manner by providing a sleeve which is on the one hand waterproof and on the other hand self-supporting.

[0028] Indeed, the cryotherapy treatment boot according to the present invention provides a solution in particular to animal owners and more particularly horse owners, owners of equestrian centers, veterinarians and animal clinics as well as athletes and riders, by providing a self-supporting sleeve which is quick and easy to install by a user thanks to the passage of at least part of the animal's leg in the open end of the sleeve and the attachment of the animal's foot by means of the attachment system of the sole device. When the foot / hoof of the animal and in particular of a horse is positioned in the boot and attached with the attachment system of the sole device, the sleeve being self-supporting is held in place, thus avoiding the need to resort to additional attachment systems which are restrictive both for the animal and for the installer and the speed of installation.

[0029] Indeed, although the solutions proposed in previous documents seek to increase the number or strengthen the attachment systems to the animal's leg, the present invention goes against these prejudices by providing a waterproof and self-supporting sleeve.

[0030] By self-supporting sleeve, it is understood according to the present invention that it is a sleeve whose stability is ensured by the rigidity of its shape.

[0031] It is thus easily understood that the waterproof and self-supporting sleeve of the care boot according to the invention is a waterproof and directly self-supporting sleeve.

[0032] Particularly advantageously, the waterproof and directly self-supporting sleeve has stability ensured by the rigidity of its shape, this making it possible to avoid having to resort to additional, supplementary, external attachment systems, thus allowing correct positioning by avoiding the steps of adjustment, additional fixing as present in the prior art. Thus, the cryotherapy care boot for animals according to the present invention, having on the one hand a sole device in order to provide an interface between the foot / hoof of the animal and the ground and also allowing easy attachment of the attachment system to the foot of the animal, and on the other hand a self-supporting waterproof sleeve, and more particularly directly self-supporting, makes it possible to provide a boot that is easy and quick to install and remove from at least part of the animal's leg.In addition, positioning and support are also facilitated by the boot according to the present invention, since the hoof and foot of the animal is housed against the inner face of the sole device inside the boot, the sleeve being self-supporting and correctly positioned, avoiding the additional adjustment, fixing and positioning steps of the prior art which are restrictive.

[0033] This advantageously allows manipulations to be carried out more quickly, thus reducing the stress, discomfort or even disturbances that the animal might feel, but also facilitating the work of the installers.

[0034] Finally, the sleeve of the care boot according to the present invention being self-supporting, directly self-supporting, in addition to providing greater comfort to the animal and ease of use, allows in particular to remain correctly in place and positioned in the position of use against and along at least one part of the leg of the animal / horse, which makes it possible on the one hand to avoid the need for additional fastening systems, and even essential in the prior art, and on the other hand which allows for increased effectiveness over time, preventing the boot from sagging or undergoing significant deformations which could cause leaks or losses of cooling liquids or solids necessary for care.

[0035] Advantageously, the self-supporting waterproof sleeve of the care boot according to the present invention is made of synthetic rubber, preferably polychloroprene-based rubber, preferably neoprene.

[0036] This has the advantage of providing a sleeve according to the present invention which is waterproof, preferably made of neoprene, which makes it possible to retain the cooling liquid and / or solid for cryotherapy treatment.

[0037] Preferably, the self-supporting waterproof sleeve of the care boot according to the present invention comprises at least one first outer membrane and at least one first waterproof inner membrane. In such an embodiment, the at least one first waterproof inner membrane is the self-supporting waterproof sleeve according to the present invention, and the first outer membrane is an additional outer membrane.

[0038] Thus, the at least one first internal waterproof membrane of the sleeve of the care boot according to the present invention is made of synthetic rubber, preferably polychloroprene-based rubber, preferably neoprene.

[0039] In addition, the additional outer membrane is a protective membrane, more specifically a protective fabric, even more specifically a water-repellent protective fabric.

[0040] This has the advantage of providing a sleeve according to the present invention comprising a first internal waterproof membrane, preferably made of neoprene, which makes it possible to retain the cooling liquid and / or solid for cryotherapy treatment and an additional external protective and / or water-repellent membrane.

[0041] Preferably, the at least one first waterproof internal membrane and / or the self-supporting waterproof sleeve of the care boot according to the present invention comprises at least one waterproof opening and closing means arranged longitudinally, possibly provided with a protective means, preferably at least one waterproof zipper possibly provided with a protective means.

[0042] This advantageously provides a quick opening and closing system for the boot according to the present invention, allowing for easier installation while reducing discomfort and stress that the animal might experience.

[0043] Furthermore, providing a means of protecting at least one zipper, such as a fabric cap or a housing into which the zipper slider / shuttle will slide, helps prevent this part from coming into direct contact with the animal's skin, thus considerably reducing the risk of injury or scratches.

[0044] Finally, providing a care boot according to the present invention which comprises at least one self-supporting waterproof sleeve and / or a first waterproof internal membrane which comprises a waterproof opening and closing system such as a waterproof zipper, makes it possible to provide a waterproof envelope within which the foot and at least part of the leg of the animal are positioned, and to be able to apply a cold treatment (water, iced water, cooling liquid and / or solid) effectively, by limiting and avoiding losses and leaks through the sleeve.

[0045] Preferably, the self-supporting waterproof sleeve of the care boot according to the present invention comprises a series of cushioning elements between the first external membrane and the first internal waterproof membrane.

[0046] Furthermore, and particularly surprisingly, the self-supporting aspect of the sleeve is reinforced by the quilting and more particularly by the quilted structure and texture of the sleeve according to the present invention.

[0047] It also appeared particularly surprisingly that, when a mixture of water or cooling liquid and ice cubes, ice or solid cooler, was used, the padding of the sleeve according to the present invention in fact made it possible to better distribute and keep in position the ice cubes or cooling solids, along the inside of the sleeve of the boot of the invention, consequently increasing the efficiency, comfort and care provided to the animals and more particularly to the horses.

[0048] Furthermore, the series of cushioning elements being positioned between the at least one first waterproof internal membrane and the at least one first external membrane, is advantageously isolated both from the internal surrounding environment of the boot which is filled with cooling liquid and / or solid in use, and also from the external surrounding environment of the boot which may be subject to bad weather, wind, rain, snow, but also to projections of pebbles, gravel, sand and other dust, in particular when an animal moves.

[0049] Thus, this makes it possible in a particularly advantageous manner to reinforce the self-supporting aspect of the sleeve of the present invention and to increase both its resistance, efficiency and duration of use over time.

[0050] It is of course understood that any other alternative system of self-supporting of the sleeve is envisaged by the present invention, for example the sleeve according to the invention may comprise a series of reinforcing rods (for example at least one, at least two, at least three, at least four, at least five, at least six, reinforcing rods).

[0051] Indeed, the sleeve of the care boot according to the present invention being waterproof and self-supporting by its shape and structure, it is obviously understood that the reinforcing elements such as a series of rods provide additional / supplementary reinforcement.

[0052] Advantageously, the series of cushioning elements of the care boot according to the present invention is oriented vertically, horizontally, helical, ordered, disordered, and their combination, preferably the series of cushioning elements is oriented vertically.

[0053] It has indeed appeared in a particularly surprising manner that providing a series of cushioning elements oriented vertically makes it possible to provide better results in terms of cryotherapy care provided to the animal, in particular due to the homogeneity of the positioning of the ice cubes and cooling solids inside the sleeve of the boot of the invention.

[0054] Additionally, providing a vertically oriented series of cushioning elements provided additional rigidity and stability to the self-supporting waterproof sleeve of the present invention.

[0055] Preferably, the series of cushioning elements of the care boot according to the present invention is chosen from foams, sausages, down, feathers, synthetic fibers, polyester wadding, polystyrene beads and combinations thereof.

[0056] More generally, the series of cushioning elements of the care boot according to the present invention is formed from any element, material or filling making it possible to form padding, preferably dense padding, preferably high density padding.

[0057] Advantageously, the self-supporting waterproof sleeve of the care boot according to the present invention comprises at the second open end at least one circumferential tightening element, for example a circumferential tightening elastic, a tightening tie, a tightening strap. It has indeed appeared advantageous to provide a circumferential tightening element at the second open end of the sleeve of the boot according to the present invention, in order to be able to tighten the second end of the sleeve, or to reduce the circumference, to stick more closely to the at least one part of the animal's paw and to further reduce the losses and leaks of cooling liquid and / or solid through the open opening of the sleeve of the boot of the invention.

[0058] Furthermore and particularly surprisingly, as mentioned above, it appeared that the boot according to the present invention could provide better results in terms of cryotherapy care, resistance and support over time, by providing a waterproof and self-supporting sleeve on the one hand and possibly supplemented by at least one circumferential tightening element, and thus limiting the additional and reinforced leg attachment systems of the prior art.

[0059] Preferably, the sole device of the care boot according to the present invention comprises a central sole portion, preferably substantially circular, and a circumferential portion, the circumferential portion comprising a series of attachment means arranged to cooperate with the attachment system on the animal's foot.

[0060] Preferably, the circumferential portion of the sole device of the care boot according to the present invention comprises a first outer wall and a second inner wall, each extending in a substantially upward direction, and a housing space between the first outer wall and the second inner wall arranged to receive the at least one first waterproof inner membrane of the sleeve.

[0061] Furthermore, the housing space between the first outer wall and the second inner wall is arranged to receive the sealed sleeve according to the invention.

[0062] Advantageously, the circumferential portion of the sole device of the care boot according to the present invention comprises a front portion and a rear portion, and wherein the front portion of the circumferential portion has an extension portion arranged to envelop a hoof of an animal in a progressively increasing manner respectively from a quarter or heel portion to a hoof toe portion, preferably the extension portion is an extension portion of the first outer wall and the second inner wall and has the housing space.

[0063] Indeed, in a particularly advantageous and surprising manner, the sole device according to the present invention, by comprising an extension part which extends progressively and increasingly to envelop the front of the hoof of an animal, and more particularly which extends increasingly from the left and right quarter or heel parts, up to the central hoof toe part, makes it possible to increase the friction force of the sole device against the hoof of the animal. This makes it possible in particular to increase the rigidity and the hold of the sole device against the animal's foot and consequently the rigidity and the hold of the care boot according to the invention, thus avoiding losses, damage or rotations of the care boot according to the invention.

[0064] Furthermore, and surprisingly and synergistically, the care boot according to the present invention, when the sole device comprises the extension part as described above, the waterproof sleeve itself comprises a bent part. It appeared that rather than weakening and weakening the rigidity, stability and self-supporting of the sleeve according to the present invention, the characteristics of the extension part in combination with a sleeve having a bent part made it possible, on the contrary, to further reinforce the rigidity, the hold and the self-supporting of the boot according to the present invention. In addition, the bent part of the sleeve according to the invention also makes it possible to provide greater comfort to the animal, as well as to facilitate installation of the care boot.

[0065] The rigidity, the hold and the self-supporting having been reinforced by the synergy of the enveloping extension part of the sole device and the waterproof sleeve according to the invention, preferably the sleeve having a bent part, it appeared that it was possible to reduce the weight and the size of the care boot according to the invention while retaining its characteristics.

[0066] Preferably, the extension part of the sole device of the care boot according to the present invention comprises on the second internal wall a series of lugs extending in a substantially upward direction and arranged to come into contact with the hoof of the animal, preferably at least two lugs, advantageously at least three lugs, preferentially at least four lugs, more advantageously at least five lugs, more preferentially at least six lugs, arranged on the periphery of said second internal wall of the extension part.

[0067] Indeed, it appeared to be particularly advantageous that having a series of lugs present on the inner face of the second internal wall of the extension part made it possible to create spaces for the circulation of a treatment liquid to the bottom of the animal's foot.

[0068] Preferably, the second internal wall of the sole of the care boot according to the present invention comprises the series of attachment means arranged to cooperate with the attachment system on the animal's foot, preferably the series of attachment means comprises at least two attachment means, preferably at least three attachment means, advantageously at least four attachment means.

[0069] It is indeed advantageous to be able to correctly and easily position the hoof / foot of the animal in the boot according to the present invention, and this quickly and easily by means of the reception area of ​​the sole against the inner face of the central part of the sole, and inside the housing defined by the circumferential part of the sole.

[0070] Additionally, it also allows, in position, to wrap the animal's hoof / foot, which provides additional protection and comfort for the animal, the horse.

[0071] Advantageously, the sole device of the care boot according to the present invention comprises a central sole part comprising an upper face arranged to be in contact with a foot of the animal, preferably with a hoof of the equine, and a lower face arranged to be in contact with the ground, the upper face of the central part of the sole being textured.

[0072] Advantageously, the textured upper face of the central sole portion of the care boot according to the present invention is provided with a series of undulations, preferably provided with a series of bands having a series of undulations, preferably provided with a series of bands having a series of undulations with a longitudinal axis in a different direction.

[0073] It has appeared to be particularly advantageous that providing a sole with a central part of the sole whose upper face is textured, makes it possible to increase the contact surface between the lower part of the hoof and the sole, even if the animal's hoof has defects, the presence of stones, gravel or stuck earth, this allows in particular for the animal, when it is equipped with the boot according to the present invention, to be able to naturally place its paw on the ground or walk, without feeling any discomfort.

[0074] This also provides additional cushioning to the animal's hoof / foot.

[0075] More advantageously, the underside of the sole device of the boot according to the present invention, preferably of the central sole part, is textured, preferably is provided with a series of undulations, preferably provided with a series of strips having a series of undulations, preferably provided with a series of strips having a series of undulations with a longitudinal axis in a different direction.

[0076] Similar to the upper face of the central part of the sole, the presence of texturing and more particularly of the series of bands presenting a series of undulations makes it possible to provide additional cushioning in relation to the ground on which the animal can move.

[0077] Furthermore, the presence of textures as well as the series of undulations and more particularly the series of bands presenting a series of undulations, on the lower face of the sole, that is to say the face in contact with the ground, advantageously allows better evacuation of water when the animal moves, thus reducing the risk of the animal slipping and falling.

[0078] Advantageously, the sole device of the care boot according to the present invention comprises at least one internal reinforcing element, preferably at least one reinforcing element positioned between the upper face and the lower face of the central sole part.

[0079] Even more advantageously, the at least one internal reinforcing element of the sole device of the care boot according to the present invention is at least one metal plate, preferably at least one pure metal plate or at least one metal alloy plate.

[0080] Alternatively, the at least one internal reinforcement element can also be an ultra-high-density foam. This provides an additional reinforcement element that can better withstand the stresses exerted on the sole, while providing greater energy return when the animal, the horse, walks.

[0081] Preferably, the system for attaching the care boot to the animal's foot according to the present invention comprises a series of retaining means arranged to cooperate directly and / or indirectly with the series of attachment means of the sole device, a series of adjustable circumferential retaining means, preferably the series of retaining means is a series of straps, for example a series of elastic straps.

[0082] More preferably, the system for attaching the boot to the animal's foot according to the present invention comprises an adjustable circumferential attachment strap, for example a strap provided with an adjustable buckle, a self-gripping strap, a self-gripping strap provided with a buckle.

[0083] Other embodiments of the care boot according to the invention are indicated in the appended claims.

[0084] The invention also relates to an animal care sole device.

[0085] Indeed, the present invention relates to a sole device for animal care, preferably for equines, comprising a system for attachment to the animal's foot, comprises a central sole part, preferably substantially circular, and a circumferential part, the circumferential part comprising a series of attachment means arranged to cooperate with the system for attachment to the animal's foot, and in that the circumferential part of the sole device comprises a front part and a rear part, and in which the front part of the circumferential part has an extension part arranged to envelop a hoof of an animal in a progressively increasing manner respectively from a quarter or heel part to a hoof toe part.

[0086] Preferably, the extension part of the sole device according to the present invention comprises on the second internal wall a series of lugs extending in a substantially upward direction and arranged to come into contact with the hoof of the animal, preferably at least two lugs, advantageously at least three lugs, preferentially at least four lugs, more advantageously at least five lugs, more preferentially at least six lugs, arranged on the periphery of said second internal wall of the extension part.

[0087] Indeed, it appeared to be particularly advantageous that having a series of lugs present on the inner face of the second internal wall of the extension part made it possible to create spaces for the circulation of a treatment liquid to the bottom of the animal's foot.

[0088] Preferably, the circumferential portion and the extension portion of the sole device according to the present invention comprise a first outer wall and a second inner wall, each extending in a substantially upward direction, and a housing space between the first outer wall and the second inner wall arranged to receive a sleeve, preferably a sealed sleeve.

[0089] More preferably, the second internal wall of the sole device according to the present invention comprises the series of attachment means arranged to cooperate with the attachment system on the animal's foot, preferably the series of attachment means comprises at least two attachment means, preferably at least three attachment means, advantageously at least four attachment means.

[0090] Furthermore, the sole device according to the present invention comprises a central sole portion comprising an upper face arranged to be in contact with a foot of the animal, preferably with a hoof of the equine, and a lower face arranged to be in contact with the ground, the upper face of the central sole portion being textured, preferably the textured upper face of the central sole portion is provided with a series of undulations, preferably provided with a series of strips having a series of undulations, preferably provided with a series of strips having a series of undulations with a longitudinal axis in a different direction and / or wherein the lower face of the sole device, preferably of the central sole portion, is textured, preferably is provided with a series of undulations, preferably provided with a series of strips having a series of undulations,preferably provided with a series of strips having a series of undulations with a longitudinal axis in a different direction. Particularly advantageously, the animal care sole device according to the present invention comprises at least one internal reinforcing element, preferably at least one reinforcing element positioned between the upper face and the lower face of the central sole part, preferably the at least one internal reinforcing element is at least one metal plate, preferably at least one pure metal plate or at least one metal alloy plate.,

[0091] Indeed, in a particularly advantageous and surprising manner, the care sole device according to the present invention, by comprising an extension part which extends progressively and increasingly to envelop the front of the hoof of an animal, and more particularly which extends increasingly from the left and right quarter or heel parts, up to the central hoof clamp part, makes it possible to increase the friction force of the sole device against the hoof of the animal. This makes it possible in particular to increase the rigidity and the hold of the sole device against the animal's foot, thus avoiding losses, damage or rotations of the care sole device according to the invention.

[0092] Furthermore, and surprisingly and synergistically, the care sole device according to the present invention, which comprises the extension part as described above, may also comprise a sleeve.

[0093] For example, a self-supporting sleeve and / or a waterproof sleeve, preferably a waterproof and self-supporting sleeve, for example a waterproof and directly self-supporting sleeve.

[0094] Such a waterproof and self-supporting sleeve, preferably waterproof and directly self-supporting, can be arranged for carrying out cryotherapy treatment as described above, having a height covering up to the animal's leg.

[0095] According to another embodiment, the waterproof and self-supporting sleeve, preferably waterproof and directly self-supporting, can be of a smaller size in order to have a height enveloping up to the knee of the animal, or even smaller in order to have a height enveloping up to the cannon or fetlock of the animal, which makes it possible in a particularly advantageous manner to provide local and specific care for the treatment of the cannon, fetlock, foot or hoof of the animal, as well as their combinations. In addition, the waterproof sleeve according to the different embodiments presented just before, for its part, can comprise an angled part.It appeared that rather than weakening and weakening the rigidity, stability and self-supporting nature of the sleeve, the characteristics of the extension portion of the care sole device according to the present invention in combination with a sleeve having an angled portion allowed on the contrary to further reinforce the rigidity, the hold and the self-supporting nature of the boot, long, short, or reduced according to the present invention. In addition, the angled portion of the sleeve also allows to provide more comfort to the animal, as well as an easier installation of the care boot.

[0096] The rigidity, the hold and the self-supporting having been reinforced by the synergy of the enveloping extension part of the care sole device according to the invention and the waterproof sleeve, preferably the sleeve having a bent part, it appeared that it was possible to reduce the weight and the size of the care boot according to the invention while retaining its characteristics.

[0097] Other embodiments of the care sole device according to the present invention are indicated in the appended claims.

[0098] The invention also relates to a method of manufacturing a care boot according to the present invention.

[0099] Other embodiments of the method of manufacturing a care boot according to the present invention are indicated in the appended claims.

[0100] The invention finally relates to the use of the care boot according to the present invention for the treatment and care of animals by cryotherapy, more particularly the treatment and care of equines such as horses, donkeys, mules, zebras, by cryotherapy.

[0101] Other embodiments of the use of the care boot according to the present invention are indicated in the appended claims.

[0102] Other characteristics, details and advantages of the invention will emerge from the description given below, without limitation and with reference to the drawings and examples.

[0110] Figure 9 shows the animal care boot according to the invention according to another embodiment, seen from the front.

[0111] Figures 10, 11, 12 and 13 show the sole device of the present invention according to another embodiment.

[0112] In the figures, identical or similar elements bear the same references.

[0113] Figures 1, 2 and 5 show the care boot 1 according to the present invention.

[0114] In these representations, the care boot 1 according to the present invention comprises a sole device 2 which comprises a system 4 for attaching to the animal's foot and a self-supporting waterproof sleeve 3 which has a first end 5 connected to the sole 2 and a second end 6 open to accommodate at least part of the leg of the animal, and more particularly of the horse. The self-supporting waterproof sleeve 3 of the care boot 1 comprises a first external membrane 7 and at least one first internal waterproof membrane 8, between which is housed a series of cushioning elements 9.

[0115] In one embodiment of the care boot 1 of the invention, the self-supporting waterproof sleeve 3 is made of neoprene.

[0116] The series of cushioning elements 9 can be chosen from foams, sausages, down, feathers, synthetic fibers, polyester wadding, polystyrene balls and their combinations and are oriented vertically in Figures 1 and 5, and horizontally in Figure 2.

[0117] On the one hand, the first waterproof internal membrane 8 is made of synthetic rubber, for example polychloroprene-based rubber and even more particularly neoprene. On the other hand, the first waterproof internal membrane 8 comprises a waterproof zipper provided with a protective means as a means of opening and closing 10 of the first waterproof internal membrane 8 and the waterproof sleeve 3 according to the invention. This allows the handler to easily slide the care boot 1 along the leg of the animal and to attach the attachment system 4 directly and easily to the foot / pastern of the animal and more particularly of the horse.

[0118] Furthermore, the sleeve 3 of the care boot 1 according to the present invention comprises a link, elastic, strap and more generally a circumferential tightening element 11 at the second open end 6.

[0119] Thus, in a particularly advantageous, surprising manner and going against the prejudices of the prior art, the care boot 1 according to the present invention, being both waterproof and self-supporting, allows rapid and easy installation thanks to the positioning of the foot / pastern and more particularly of the hoof of the animal / horse directly on the sole device 2, via the tightening of the attachment system 4 and the adjustable circumferential retaining means 23 such as a tightening strap, and thanks to the self-supporting aspect of the sleeve 3 to retain its boot shape while avoiding on the one hand the sagging or deformation of the structures of the prior art, and on the other hand to avoid resorting to additional fixing and tightening devices.In operation, the care boot 1 according to the invention is installed around the horse's foot / pastern, and will be filled with at least one cooling liquid and / or cooling solid such as, for example, water and ice cubes in order to provide care to the lower limb, treatment of injuries, for the rapid and effective recovery of the animal's muscles or for comfort to refresh the muscles after exercise.

[0120] Surprisingly, the waterproof and self-supporting sleeve 3 allows these treatments, care or comfort actions to be carried out easily and conveniently.

[0121] Figures 3, 4A, 4B and 4C show the sole device 2 of the care boot 1 according to the present invention in more precise and detailed manner, according to a first embodiment.

[0122] Furthermore, the sole device 2 as illustrated in figures 3, 4A, 4B and 4C, comprises a central sole part 12 with an upper face 18 arranged to be in contact with the hoof of the animal and more particularly of the horse, and a lower face 19 arranged to be in contact with the ground.

[0123] In addition, as shown, the upper face 18 and the lower face 1 are textured and more particularly have a series of undulations 20, 21, and even more particularly are provided with a series of strips having a series of undulations with a longitudinal axis in a different direction. This makes it possible to increase the contact surface between the lower part of the horse's hoof and the sole, even if the animal's hoof has defects, stones, gravel or other earth which could be stuck, thus the animal or horse can naturally place its paw / foot on the ground or chew, without feeling any discomfort when equipped with the care boot 1 according to the invention. In addition, the undulations 21 on the lower face 19 of the sole 2 make it possible to provide additional cushioning to the horse, thus improving its comfort, in addition this also makes it possible to evacuate water more optimally when moving and to prevent the animal from slipping.

[0124] In addition, as appears from Figures 4C and 5, the sole device 2 of the care boot 1 according to the invention comprises in particular an internal reinforcing element 22, positioned between the upper face 18 and the lower face 19 of the first central part 12, such as for example a metal plate, or an ultra-high density foam, which makes it possible to even better support the tensions exerted on the sole, while providing greater energy return when the animal moves, thus improving its comfort.

[0125] More particularly, the sole device 2 of the care boot 1 according to the invention comprises a circumferential part 13 with four attachment means 14 which cooperate with the attachment system 4 on the animal's foot. In particular, the circumferential part 13 has a first external wall 15, a second internal wall 16 which each extend vertically and which define a housing space 17 in which the first sealed internal wall 8 of the sleeve 3 is housed, for example by gluing or sealed stitching.

[0126] Finally, the attachment system 4 to the horse's foot as shown comprises four connecting loops which cooperate respectively with the four attachment means 14, thus the retaining means 23 of the attachment system 4 cooperates directly or indirectly with the sole 2 of the care boot 1 of the invention by means of the four attachment means 4. As shown, the retaining means is a self-gripping strap.

[0127] Any other alternative or equivalent system of self-supporting the sleeve is envisaged by the care boot 1 according to the present invention, for example a waterproof sleeve comprising a series of reinforcing rods.

This makes it possible in particular to increase the rigidity and the hold of the sole device against the animal's foot and consequently the rigidity and the hold of the care boot 1 according to the invention, thus avoiding losses, damage or rotations of the care boot according to the invention.

[0136] Furthermore, and surprisingly and synergistically, the care boot 1 according to the present invention, comprising the sole device 2 which has the extension part 24 as described above, the waterproof sleeve 3 for its part comprises an angled part 26, making it possible to provide greater comfort to the animal, as well as easier installation of the care boot 1. The rigidity, the hold and the self-supporting having been reinforced by the synergy of the enveloping extension part 24 of the sole device 2 and the waterproof sleeve 3 according to the invention, in particular of the sleeve 3 having an angled part 26, it appeared that it was possible to reduce the weight and the size of the care boot 1 according to the invention while retaining its characteristics (embodiments of Figs. 6 to 9, and embodiment of the high care boot Fig. 8 and low care boot Fig. 9).

[0137] Furthermore, the extension part 24 of the sole device 2 comprises on its internal periphery, arranged to be in contact with the hoof of the animal, more particularly at the level of the second internal wall 16, a series of lugs 25, in particular six lugs 25 arranged on the periphery of the second internal wall 16 of the extension part 24.

[0138] Indeed, it appeared to be particularly advantageous that having a series of lugs 25 present on the inner face of the second inner wall 16 of the extension part 24 made it possible to create spaces for the circulation of a care liquid to the bottom of the animal's foot.

[0139] Figures 10, 11, 12 and 13 show the sole device of the present invention according to another embodiment.

[0140] Indeed, figures 10 and 11 represent the sole device 2 according to the invention in rear view respectively without fixing the attachment system 4 to the animal's foot, and with the fixing of the attachment system 4 to the animal's foot.
