Description

Horse Gum Protection Technical Field

[0001] According to a first aspect, the invention relates to a guard for preventing direct contact between a mandibular bar of a horse and a bit installed in a mouth of the horse. The invention also provides a method for attaching such a guard to the lower jaw of a horse. The invention further provides a method and a protective element for protecting a mandibular bar of a horse. State of the art

[0002] A horse bit allows a rider to influence the horse's mouth through the reins. This allows the rider to indicate a direction to the horse. A bit is typically placed across the horse's mouth and at the corners of the mouth. Generally, the bit inserted in the horse's mouth rests on parts of the horse's gums covering each of the horse's two mandibular bars. The mandibular bars of the horse are spaces in the lower jaw without teeth and located between the premolars and the incisors, or between the premolars and the canines if the horse has canines. The bit installed in the horse's mouth is therefore in direct contact with the gum of the mandibular bars.

[0003] The bit installed in the horse's mouth moves relative to the jaws, especially when the rider pulls on the bit by pulling on the reins attached to it. The bit then rubs against the gums of the mandibular bars and injures the gums. Such injuries make the rubbing of the bit on the gums more painful and lead to hypersensitivity. This negatively impacts the horse's well-being.

[0004] In addition, the pain caused by the bit rubbing against the horse's gums causes a loss of contact in the communication between the horse and its rider. This negatively impacts the horse's responsiveness to its rider's instructions, and therefore the sporting performance of both horse and rider during competitions.

[0005] WO201039025A1 describes a device for placement in a horse's mouth, including protective portions for covering the bars. When the device is placed in a horse's mouth, it is secured both around the teeth and between the horse's front teeth and molars. Maintaining such a device in a horse's mouth therefore requires a design adapted to the shape of the jaw and teeth of each particular horse, so as to fit it.

[0006] There is therefore a need for a protection which makes it possible to avoid direct contact between a bit inserted in the mouth of a horse and the mandibular bars of the latter, and which has reduced adaptations required to be maintained in position in the mouth of a particular horse. Summary of the invention

[0007] One object of the present invention is to provide a horse gum guard which minimizes the adaptations required to be held in position in the mouth of a particular horse.

[0008] According to a first aspect, the invention relates to a horse gum protector comprising: - an inner holding portion comprising a protective element and configured to be positioned in a mouth of a horse such that the protective element prevents direct contact between a mandibular bar of the horse and a bit inserted in the mouth of the horse, - an outer holding portion to be positioned outside the mouth of the horse against a posterior part of a head of the horse.

[0009] Compared to the prior art, the protection according to the invention does not require custom manufacturing to ensure its retention in the mouth of a particular horse. Thanks to the presence of the inner and outer retention portions, it is not necessary to match the shape of the jaw and teeth of the horse with the protection to ensure its retention in the horse's mouth.

[0010] The protection according to the invention is configured to protect at least a portion of horse gum covering a mandibular bar from the friction generated by movement of the bit in the horse's mouth.

[0011] The guard according to the invention is preferably configured to be coupled to a lower jaw of the horse when: - the inner holding portion is positioned in the horse's mouth so that the guard prevents direct contact between the horse's mandibular bar and the bit in the horse's mouth, and - the outer holding portion is positioned outside the horse's mouth and against the rear portion of the horse's head.

[0012] Preferably, the guard is configured to be coupled only to the horse's lower jaw. Such a guard helps avoid unnecessarily constraining movements between the horse's jaws.

[0013] Preferably, the outer holding portion is configured to be positioned against the chin and / or the head trough of the horse. In this way, protection can be achieved with reduced bulk.

[0014] The hind part of the horse's head includes the chin and the horse's head trough.

[0015] When the guard is coupled to the horse's lower jaw, the outer holding portion is preferably configured to contact the rear portion of the horse's head. The contact between the outer holding portion and the rear portion of the horse's head may be direct or indirect. For the purposes of this application, such an outer holding portion may also be referred to as a 'rear head contact portion', or 'rear head contact outer portion'. For the purposes of this application, the outer holding portion may also be referred to as a 'trough contact portion', or 'trough contact outer portion' when the outer holding portion is configured to be positioned against the trough of the horse's head.For purposes of this application, the outer holding portion may also be referred to as a 'chin contact portion', or 'outer chin contact portion' when the outer holding portion is configured to be positioned against the chin of the horse's head.

[0016] The outer holding portion may include a head rear contact surface. The head rear contact surface head is in contact with the posterior portion of the horse's head when the guard is coupled to the horse's lower jaw. In other words, the outer holding portion is in contact with the posterior portion of the horse's head through the posterior head contact surface when the guard is coupled to the horse's lower jaw. The contact between the posterior head contact surface and the posterior portion of the horse's head may be direct or indirect.

[0017] Alternatively, the head hind portion contact surface may be referred to as a 'trough contact surface' or 'chin contact surface' when the outer holding portion is configured to be positioned against the trough and / or chin of the horse's head, respectively.

[0018] Preferably, the shield is configured so that the outer holding portion is held against the rear portion of the horse's head by a bridle attached to the horse's head when the shield is coupled to the horse's jaw. This allows the coupling between the shield and the horse's head to be maintained reliably, even in the event of sudden movement of the horse's head.

[0019] Preferably, the outer holding portion is configured to be held against the rear portion of the horse's head by a bridle attached to the horse's head, preferably by a strap of the bridle attached to the horse's head. Preferably, the bridle prevents the outer holding portion from moving away from the rear portion of the horse's head. Preferably, the outer holding portion is configured to be positioned between the rear portion of the horse's head and a portion of the bridle surrounding the horse's head. Preferably, the outer holding portion is configured to be positioned between the rear portion of the horse's head and a portion of the bridle surrounding the horse's head such that the bridle prevents movement of the outer holding portion in a direction normal to a portion of an outer surface of the rear portion of the horse's head in contact with the outer holding portion.

[0020] Preferably, the outer holding portion has a shape configured to limit lateral movements of the holding portion. external to the horse's lower jaw when the guard is coupled thereto. Preferably, such an external holding portion partially conforms to a shape of the rear portion of the horse's head. Preferably, such an external holding portion partially surrounds the rear portion of the horse's head.

[0021] In a preferred embodiment of the invention, the outer holding portion includes a bridle contacting surface opposite the rear head contacting surface. The shield is configured such that the bridle, preferably the bridle strap, contacts the bridle contacting surface when the outer holding portion is held against the rear head of the horse by the bridle attached to the horse's head.

[0022] Preferably, the bridle contact surface comprises one or more protrusions. Each protrusion projects from the bridle contact surface. Each protrusion extends from the bridle contact surface. Each protrusion preferably extends at least in a direction normal to the bridle contact surface. The protrusions are spaced apart to allow positioning of the bridle strap between the protrusions when the outer holding portion is held against the rear portion of the horse's head by the bridle attached to the horse's head. The protrusions are configured to prevent movement of the strap along the bridle contact surface. Such protrusions therefore allow for better retention of the shield by means of the bridle by preventing the strap from sliding past the bridle contact surface of the outer holding portion.

[0023] In a preferred embodiment, the inner holding portion is coupled to the outer holding portion through a joining portion. The joining portion connects the inner and outer holding portions. Preferably, the joining portion is configured to contour the horse's lower jaw when the guard is coupled to said lower jaw. The joining portion preferably has an arcuate portion.

[0024] In a preferred embodiment, the guard according to the invention comprises two side parts each comprising an inner holding portion, the guard being configured such that the protective element of each side part prevents direct contact between a respective mandibular bar and the bit. In this way, the guard makes it possible to protect the two mandibular bars of a horse from the friction of a bit.

[0025] The protection according to the invention therefore preferably comprises two lateral parts. Each lateral part comprises an inner holding portion comprising a respective protective element. The inner holding portions are configured to be both positioned in the mouth of a horse such that each protective element prevents direct contact between a respective mandibular bar and the bit inserted in the horse's mouth.

[0026] Such a guard comprising the two side portions is preferably configured to be coupled to the horse's lower jaw when: - the inner holding portions are positioned in the horse's mouth such that their respective protective elements each prevent direct contact between one of the horse's mandibular bars and the bit inserted in the horse's mouth, and - the outer holding portion is positioned outside the horse's mouth and held against the rear portion of the horse's head, preferably by a strap of a bridle attached to the horse's head.

[0027] In the context of this application, coupling the guard to the horse's lower jaw means that the guard is attached to the horse's lower jaw.

[0028] In a preferred embodiment, the shield comprises two joining portions, and each side portion is mechanically coupled to the outer holding portion through a respective one of the joining portions, the two side portions preferably being symmetrical about a plane of symmetry of the shield. Preferably, the joining portions are configured to laterally contour the horse's lower jaw on either side of the horse's lower jaw. In this way, the The joining portions help limit the movement of the guard in the lateral direction of the horse's lower jaw when the guard is coupled to the horse's lower jaw. This helps maintain correct positioning of the guard in relation to the horse's lower jaw.

[0029] Preferably, the protective element is removably attached to a mechanical coupling portion of the inner holding portion. In this way, it is possible to replace the protective element(s) of the protection without replacing the entire protection. Such a protection further allows the attachment of protective elements formed from material of different respective hardnesses. For example, a more or less soft protective element can be chosen depending on the sensitivity of the horse.

[0030] Preferably, the protective element is attachable to a coupling portion of the inner holding portion by threading. For example, the coupling portion of the inner holding portion comprises a rod for being threaded into a housing of the protective element. Such a protective element may be according to the fourth aspect of the invention described below. Alternatively or concomitantly, the protective element is attachable to the coupling portion of the inner holding portion by gluing.

[0031] Alternatively, the inner holding portion comprising the protective element may be in one piece. In the case where the inner holding portion comprising the protective element is in one piece, this means that the protective element cannot be decoupled from the inner holding portion and that the inner holding portion comprising the protective element is made of a single piece.

[0032] In such a configuration where the inner holding portion comprising the protective element is in one piece, the protective element may be according to the fourth aspect of the invention, but without the housing for receiving a rod.

[0033] Preferably, the protective element comprises a main tab for at least partially covering the mandibular bar. This simplifies the design of the protective element to avoid direct contact between the bit and the horse's gum.

[0034] The guard is preferably configured to extend into a space between the incisors (or canines if the horse has them) and the premolars of a horse when the guard is coupled to the lower jaw of a horse. Typically, the distance between the incisors and premolars of a horse is 7 cm. A typical length of the main tab measured along an X axis is therefore 7 cm.

[0035] In one embodiment, a length of the main tab of the protective element measured along the X axis of the protective element is between 3 and 10 cm, preferably between 5 and 8 cm. In one embodiment, a width of the main tab of the protective element measured along a Y axis of the protective element orthogonal to the X axis is between 2 and 5 cm, preferably between 3 and 4 cm. The guard is preferably configured such that the longitudinal direction of the main tab is aligned with a length direction of the mandibular bar protected by the main tab when the guard is coupled to the lower jaw of a horse. The length direction of the mandibular bar corresponds to an axis passing through an incisor and a premolar adjacent to said mandibular bar.

[0036] The guard according to the invention is preferably configured so that the guard prevents direct contact between the horse's mandibular bar and the bit inserted into the horse's mouth when the inner holding portion is positioned in the horse's mouth relative to the mandibular bar and the outer holding portion is positioned outside the horse's mouth against the rear portion of the horse's head.

[0037] The inner retaining portion is preferably configured to allow positioning of the guard relative to a lower jaw of the horse. The inner retaining portion is preferably configured to allow positioning of the guard relative to a tooth, preferably a premolar adjacent to the mandibular bar, of a lower jaw of the horse. The inner retaining portion may be configured to allow positioning of the guard relative to a mandibular bar.

[0038] In this application, it will be clear to the person skilled in the art that the term mandibular bar designates a part of the horse's lower jaw which does not have any teeth and separates a premolar and an incisor (or possibly a canine if the horse has one), the mandibular bar comprising a gum which covers it.

[0039] The inner retaining portion includes a protective element for protecting the horse's gum. The inner retaining portion is configured to be positioned in the horse's mouth such that the protective element prevents direct contact between a mandibular bar of the horse and a bit inserted in the horse's mouth, i.e., between the gum of the mandibular bar and the bit.

[0040] The protective element of the inner holding portion is preferably configured to contact the mandibular bar of the horse when the guard is coupled to the horse's lower jaw. The contact between the protective element and the mandibular bar may be direct or indirect. For the purposes of this application, such a protective element may also be referred to as a 'gingival contact element', or 'gingival contact element', or 'mandibular bar contact element'.

[0041] The protective element may include a gingival contact face. The gingival contact face contacts the mandibular bar of the horse when the guard is coupled to the horse's lower jaw. In other words, the protective element of the inner holding portion contacts the mandibular bar of the horse through the gingival contact face when the guard is coupled to the horse's lower jaw. The contact between the gingival contact face and the mandibular bar may be direct or indirect. More specifically, the contact occurs between the gingival contact face and the gingiva of the mandibular bar.

[0042] Preferably, the gingival contact face comprises a curved and concave portion for receiving the mandibular bar. This makes it possible to at least partially cover and surround a mandibular bar of the horse when the protection is coupled to the mandible of the horse. This allows for better retention of the protection in the mouth of the horse.

[0043] Preferably, the protective element comprises a protruding portion, also referred to as a rim in the present application, for being positioned between the tongue and the mandibular bar of the horse when the guard is coupled to the lower jaw of the horse.

[0044] For the purposes of this application, the gingival contact face of the protective element may also be referred to as the 'gingival contact surface' or 'mandibular bar contact face'.

[0045] Each protective element may include a mandibular bar contact surface for contacting a respective mandibular bar.

[0046] Similarly, where the guard comprises a plurality of (typically 2) outer retaining portions, each outer retaining portion may comprise a rear head contacting surface for contacting a respective portion of the rear head of the horse, e.g., the chin or the chin.

[0047] In one embodiment of the invention, the shield comprises a transverse plane. The transverse plane separates the gingival contact face(s) from the posterior head contact surface(s) of the shield. In other words, the gingival contact faces and the posterior head contact surfaces are located on either side of the transverse plane. The gingival contact face(s) are oriented toward a first face of the transverse plane. The posterior head contact surface(s) are oriented toward a second face of the transverse plane opposite the first face of the transverse plane.Such a configuration ensures that the protection remains on the horse's head because, when the protection is coupled to the horse's head: - the gingival contact faces prevent downward movement of the protection, i.e. towards the rear part of the horse's head, - the contact surfaces of the rear part of the head prevent upward movement of the protection.

[0048] Preferably, the transverse plane is orthogonal to the plane of symmetry of the shield. Preferably, the shield is configured such that the transverse plane is substantially parallel to the length direction of each of the mandibular bars when the protection is coupled to the horse's head.

[0049] Preferably, the guard is configured to be coupled to a lower jaw of the horse such that: - the guard member at least partially covers the mandibular bar, or each of the guard members at least partially covers a respective mandibular bar, and - the outer holding portion is positioned against the posterior portion of the horse's head and preferably held against the posterior portion by the bridle attached to the horse's head, - preferably, the joining portions laterally contour the horse's lower jaw on either side of the horse's lower jaw.

[0050] Such protection comprising the joining portions configured to laterally bypass the horse's lower jaw on each side thereof allows the bit to retain freedom of action when the protection is coupled to the lower jaw.

[0051] Generally speaking, the horse's lower jaw is also referred to as the 'mandible'.

[0052] In a preferred version of the protection according to the invention, the inner holding portion(s) are configured to allow positioning of the protection relative to a mandibular bar of the horse, preferably relative to teeth (e.g. premolars and / or incisors) and to a gum of the lower jaw of the horse. Each inner holding portion is preferably configured to allow positioning of the protection relative to the jaw of the horse, preferably relative to a mandibular bar of the horse. Preferably, each inner holding portion is configured to allow positioning of the protection relative to teeth (e.g. premolars and / or incisors of the lower jaw) and / or to a gum covering the mandibular bar.

[0053] Preferably, each inner retaining portion is configured to extend along a respective mandibular bar between the incisor (or canine if the horse has one) and premolar adjacent to said bar. mandibular. In this way, the incisor (or canine if the horse has one) limits the movement of the inner retaining portion forward in the horse's mouth when the guard is coupled to the horse's mouth. In other words, the incisor (or canine if the horse has one) serves as a stop limiting the movement of the inner retaining portion forward in the horse's mouth. Alternatively or concomitantly, the premolar limits the movement of the inner retaining portion backward in the horse's mouth when the guard is coupled to the horse's mouth. In other words, the premolar serves as a stop limiting the movement of the inner retaining portion backward in the horse's mouth.

[0054] Each inner retaining portion is preferably configured to be positioned on a respective mandibular bar. This helps limit downward movement of the guard into the horse's mouth when the guard is coupled to the horse's mouth.

[0055] Preferably, the inner retaining portions have shapes configured to limit lateral movement of the shield in the horse's mouth when the shield is coupled to the horse's mouth. For example, such inner retaining portions are configured to conform to a surface of the portion of the gum covering the mandibular bars and / or partially surround the mandibular bars.

[0056] In an exemplary embodiment of the protection according to the invention, the coupling portion(s) of the inner holding portions, the outer holding portion and the joining portions are in a single piece, i.e., monobloc. Preferably, the coupling portion(s) of the inner holding portions, the outer holding portion and the joining portions are made of thermoplastic, for example polypropylene, polyamide, elastomer thermoplastic, or polyurethane thermoplastic. This facilitates the manufacture of the protection.

[0057] Preferably, the protective element(s) are made of thermoplastic such as elastomeric thermoplastic or polyurethane thermoplastic. These materials make the protective elements in contact with the gums more flexible and / or smoother, which improves the horse's comfort.

[0058] Preferably, the outer holding portion has a rear head contact surface configured to be brought into contact with the rear part of the horse's head and at least partially covered with a layer of flexible and / or soft material such as a foam, latex or a material from the thermoplastic family. Preferably, the rear contact surface comprises a thermoplastic. In this way, the outer holding portion is at least partially covered with a layer of flexible and / or soft material such as thermoplastic, foam, or latex. Preferably, the shield is configured such that said rear head contact surface comprising the layer of flexible and / or soft material is in contact with the rear part of the head when the shield is coupled to the lower jaw of the horse.This improves the horse's comfort and reduces the risk of injury caused by movement of the outer support portion in contact with the horse's skin and / or coat.

[0059] In one embodiment, the outer holding portion extends in a first direction over a distance of between 3 and 10 cm, preferably between 5 and 8 cm. In one embodiment, the outer holding portion extends in a second direction orthogonal to the first direction over a distance of between 8 and 15 cm, preferably between 10 and 14 cm. Preferably, the outer holding portion is configured to extend on either side of the horse's trough in the lateral direction of the horse's head when the protection is coupled to the horse's lower jaw, preferably so as to surround the horse's trough.

[0060] By virtue of the presence of the inner and outer holding portions, the shield according to the invention minimizes the adaptations required to couple the shield to the lower jaw of a particular horse. The shield according to the invention further offers the following advantages. It contributes to facilitating and securing the installation of the shield on a horse. Indeed, the outer holding portion of the shield can constitute a gripping element allowing a person to install the shield in the horse's mouth without inserting their hands inside the horse's mouth, and in particular without passing their hands between the horse's jaws. This contributes to facilitating and securing secure the installation of the protection on a horse. The protection according to the invention further eliminates the need to glue the protection in the horse's mouth to be coupled to the horse's jaw. Finally, the outer holding portion is located outside the horse's mouth when the protection is coupled to the horse's lower jaw. The outer holding portion is therefore easily visible from outside the horse's mouth. This makes it easier to detect incorrect positioning of the gum protection relative to the horse's mouth. The protection according to the invention therefore makes it possible to protect the horse's gum more reliably.

[0061] According to a second aspect, the invention relates to a method for attaching, i.e., coupling, a horse gum shield to a mandible of a horse. The horse gum shield may be according to the first aspect of the invention, but need not be. The method comprises the steps of: - positioning an inner holding portion in a horse's mouth of the horse such that a protective element of the inner holding portion prevents direct contact between a mandibular bar of the horse and a bit inserted in the horse's mouth; - positioning an outer holding portion of the shield outside the horse's mouth and against a posterior portion of the horse's head.

[0062] The horse gum protector may comprise two inner retaining portions. In this case, the method may comprise, for each of the two inner retaining portions, a respective step of: - positioning an inner retaining portion in a horse's mouth such that the protective element of the inner retaining portion prevents direct contact between a mandibular bar of the horse and the bit inserted in the horse's mouth.

[0063] Preferably, the method according to the invention comprises a step of: - maintaining the outer holding portion in contact with the rear part of the horse's head by means of a bridle attached to the horse's head.

[0064] Preferably, the method according to the invention comprises: - position the outer holding portion of the protection between the rear part of the horse's head and a strap of a bridle attached to the horse's head so as to keep the outer holding portion in contact with the rear part of the horse's head.

[0065] In the method according to the invention, the inner holding portion is preferably positioned in the horse's mouth so that the protective element at least partially covers the mandibular bar. This makes it possible to prevent direct contact between the bit positioned in the horse's mouth and the bit inserted in the horse's mouth and in contact with the corners of the horse, so that the bit is indirectly supported by the mandibular bar through the protective element.

[0066] This method allows the protection to remain attached to the horse's jaw even in the event of sudden movement of the horse's head.

[0067] According to a third aspect, the invention relates to a method for protecting a gum of a horse. The method comprises the steps of: - at least partially covering a mandibular bar in the horse's mouth with a protective element, - positioning the outer holding portion outside the horse's mouth against a posterior part of the horse's head, - positioning a joining portion mechanically coupling the protective element to the outer holding portion such that, when the protective element at least partially covers the mandibular bar and the outer holding portion is positioned outside the horse's mouth against the posterior part of the horse's head, the joining portion bypasses the horse's lower jaw.

[0068] In the method, the joining portion is preferably positioned to at least partially, and not entirely, contour the horse's lower jaw.

[0069] Preferably, the joining portion is positioned to laterally bypass the horse's jaw, i.e., passing through one side of the horse's jaw.

[0070] It is possible to protect both mandibular bars of a horse with two respective protective elements. In this case, the method can include, for each protective element and its respective mandibular bar, the step of: - at least partially covering the mandibular bar with the protective element.

[0071] In such an embodiment of the method, each protective element is preferably mechanically coupled to the outer holding portion by a respective joining portion. In this case, the method may comprise the following step twice, for each of the joining portions and its respective protective element: - positioning the joining portion mechanically coupling the protective element to the outer holding portion such that, when the protective element at least partially covers the mandibular bar and the outer holding portion is positioned outside the horse's mouth against the posterior part of the horse's head, the joining portion bypasses the horse's lower jaw.

[0072] In such an embodiment, the joining portions preferably laterally circumvent the horse's lower jaw, and on opposite sides of the horse's head.

[0073] In the present application, the term lateral to characterize the positioning relative to the head or jaw of the horse designates the positioning in a direction normal to the sagittal plane of the horse's head. Lateral faces of the horse's head are therefore located on either side of the sagittal plane.

[0074] In the method according to the third aspect, the protective element and the outer holding portion are positioned such that the joining portion contours the lower jaw of the horse when the protective element at least partially covers the mandibular bar in the horse's mouth and the outer holding portion is positioned outside the horse's mouth against the posterior portion of the horse's head.

[0075] In the method, the protective element positioned in the horse's mouth at least partially covers the mandibular bar so as to prevent direct contact between the mandibular bar, i.e., the gum covering the mandibular bar, and a bit inserted in the horse's mouth.

[0076] In one embodiment, an inner retaining portion includes the protective member. The inner retaining portion is positioned in the horse's mouth such that the protective member prevents direct contact between the mandibular bar and a bit inserted into the horse's mouth.

[0077] Such a method prevents direct contact between the gum of the mandibular bar and a bit inserted in the horse's mouth. Thanks to the method, the horse's gum is protected in a simple, robust way. The method ensures correct positioning of the protective element in relation to the mandibular bar, and without the need for custom manufacturing of the protective element. Thanks to the method, the same protective element can be used by different horses with jaws of different shapes and / or dimensions.

[0078] In the method, the joining portion preferably partially circumvents the horse's lower jaw, and preferably laterally relative to the horse's mouth. The joining portion may form an arc and / or include a curved portion.

[0079] In the method, the protective element is positioned in the horse's mouth. The protective element at least partially covers the gingiva of the mandibular bar. The protective element is positioned so as to prevent direct contact between the gingiva of the mandibular bar and a bit inserted in the horse's mouth.

[0080] The protective element and the outer holding portion are mechanically coupled by a joining portion. In the method, the joining portion is positioned relative to the horse's lower jaw such that, when: - the protective element is positioned in the horse's mouth and at least partially covers the mandibular bar so as to prevent direct contact between the mandibular bar and the bit inserted in the horse's mouth, and - the outer holding portion is positioned outside the horse's mouth and against the posterior portion of the horse's head, the joining portion partially bypasses the horse's lower jaw.

[0081] Preferably, the method comprises the step of: - hold the outer holding portion against the rear part of the horse's head by means of a bridle attached to the horse's head.

[0082] Preferably, the outer holding portion is positioned between a strap of the bridle and the rear portion.

[0083] The steps and / or features of the methods according to the second and third aspects of the invention may be combined. These methods are preferably carried out using the protection according to the first aspect of the invention, but not necessarily.

[0084] According to a fourth aspect, the invention provides a protective element for horse gums, comprising a main tab extending: - along an X axis over a length separating front and rear ends of the main tab, and - along a Y axis over a width separating first and second lateral edges of the main tab, and - along the Z axis from a gingival contact face and over a thickness, the X, Y, Z axes being orthogonal to each other. The main tab is configured to cover a mandibular bar of a horse's mouth when the gingival contact face is positioned against the mandibular bar.

[0085] Preferably, the length of the main tab is between 4 and 15 cm, preferably between 6 and 10 cm, preferably between 6.5 and 7.1 cm, and preferably equal to 6.8 cm.

[0086] Preferably, the width of the main tab is between 2 and 40 mm, preferably between 5 and 25 mm. Preferably, the width of the main tab varies along the X axis, preferably monotonically between the front and rear ends of the main tab. Preferably, said width at the front end of the protection is between 3 and 8 mm. Preferably, said width at the rear end of the protection is between 15 and 25 mm.

[0087] Preferably, the thickness of the main tab is between 2 and 15 mm, preferably between 3 and 6 mm, preferably equal to 4 mm.

[0088] The main tab may be configured to at least partially or fully cover a mandibular bar of a horse's mouth when the gingival contact face is positioned against the mandibular bar.

[0089] When the gingival contact face of the main tab is positioned against the mandibular bar, the gingival contact face is oriented towards the mandibular bar, in direct or indirect contact with the mandibular bar.

[0090] The main tab is configured to prevent direct contact between a horse's mandibular bar and a bit positioned in the horse's mouth when the gingival contact face is positioned against the horse's mandibular bar.

[0091] Such a protective element prevents direct contact between a horse's mandibular bar and a bit positioned in the horse's mouth. Such a protective element limits, or even eliminates, the adaptations necessary for use with different horses. Such a protective element is also replaceable once worn.

[0092] The dimensions of the main tab are chosen so that it can be positioned on the mandibular bar of a horse, inserting it between the teeth adjacent to the mandibular bar. Preferably, the main tab is configured to extend over the mandibular bar between an incisor (or a canine if the horse has one) and a premolar adjacent to the mandibular bar.

[0093] The main tab may be continuous, and / or include through openings, and / or include depressions, and / or include bumps, and / or include a curved portion.

[0094] Preferably, the main tab extends longitudinally along the X axis, i.e. mainly along the X axis. The main tab extends transversely along the Y axis.

[0095] Preferably, the main tab extends along the X axis and in the direction of an increase in X from the front end to the rear end of the main tab.

[0096] The length of the main tab is measured along the X axis. The width of the main tab is measured along the Y axis. The thickness of the main tab is measured along the Z axis. The axes are integral with the protective element.

[0097] Preferably, the protective element has a housing for receiving a rod, the housing extending along the first lateral edge of the main tab between a first end of the housing provided with an opening for inserting the rod and a second end of the housing. The housing may extend along at least a portion and preferably along an entirety of the first lateral edge.

[0098] Preferably, the first and second ends of the housing are located on the side of the front and rear ends of the tab, respectively, along the X axis.

[0099] The housing preferably extends, along the X axis and in the direction of increase of X, beyond the rear end of the main tab, such that the second end of the housing is located beyond the rear end of the main tab along the X axis and in the direction of increase of X.

[0100] The housing extends longitudinally along the X axis. Preferably, the housing is configured to insert the rod therein by translation along the X axis.

[0101] Preferably, an internal diameter of the housing measured in a plane normal to the X axis is between 2 and 6 mm. Preferably, a housing depth measured along the X axis is between 5 and 10 cm.

[0102] Preferably, the housing is a rectilinear sheath capable of receiving a rectilinear rod.

[0103] Preferably, the protective element comprises a coupling portion for coupling the element to a holding structure. The holding structure and the coupling portion may be included in a protection according to the first aspect of the invention when coupled. The coupling portion may comprise the housing for receiving a rod of the holding structure. For example, the rod of the holding structure is included in the inner holding portion or the joining portion of the protection according to the first aspect of the invention.

[0104] The protective element preferably comprises a rim extending along the second lateral edge of the main tab, the rim extending along the Z axis from the gingival contact face.

[0105] The rim is configured to be positioned between the horse's tongue and the mandibular bar when the guard is installed in the horse's mouth with the gingival contact face against the mandibular bar. In this way, the rim and the main tongue partially surround the mandibular bar. This allows for better maintenance of the position of the guard relative to the horse's mandibular bar.

[0106] Preferably, the rim extends along the Z axis and along the direction of decrease of Z over a distance of between 4 and 9 cm, preferably between 5 and 8 cm from the gingival contact face to a free end of the rim.

[0107] The rim therefore forms an angle with the main tab. The rim protrudes from the gingival contact face. The rim is preferably stationary relative to the main tab.

[0108] The protective element preferably comprises a flap having a joining edge attached to the rear end of the main tab and a free edge opposite the joining edge.

[0109] The flap is preferably configured so that the free edge is movable relative to the main tab. The flap is preferably configured so that the joining edge is stationary relative to the main tab. Such a flap is preferably orientable relative to the main tab.

[0110] The flap is preferably flexible. The flap is bendable relative to the main tab so as to extend primarily along the Z axis. In other words, the flap is preferably orientable relative to the main tab so as to extend along the Z axis and in the direction of growth of Z from the joining edge coupled to the main tab to the free edge.

[0111] The flap is positionable to extend on the opposite side (along the Z axis) to the rim relative to the main tab. The protective element is configured so that the flap can rest against the premolar adjacent to the mandibular bar when the main tab covers the mandibular bar with the gingival contact face positioned against the mandibular bar.

[0112] In this way, when the gingival contact face of the guard is positioned against the mandibular bar, the flap can be positioned against a premolar adjacent to the mandibular bar so as to prevent direct contact between the bit positioned in the horse's mouth and the premolar. Such a protective element makes it possible to protect the premolar from contact with the bit, in addition to the mandibular bar.

[0113] Preferably, the protective element is a single piece.

[0114] Preferably, the protective element is formed from a single material, for example thermoplastic. Alternatively, the main tab may be formed from a different material than the flap or housing or rim.

[0115] The protection according to the first aspect of the invention may comprise one and preferably two protection elements according to the fourth aspect of the invention.

[0116] The advantages cited above for protection apply mutatis mutandis to the methods and the protective element according to the invention. Brief description of the figures

[0118] The drawings of the figures are not to scale. Generally, like elements are denoted by like references in the figures. The presence of reference numbers in the drawings should not be considered limiting, including when these numbers are indicated in the claims. Detailed description of certain embodiments of the invention

[0119] Figures 1 to 5 show an exemplary embodiment of a protection 1 according to the invention, to prevent direct contact between the gums covering the mandibular bars of a horse and a bit installed in the horse's mouth. The bit or mouthpiece is generally installed in the horse's mouth so as to be in contact with the corners of the horse's lips. The bit installed in the mouth generally passes right through it and is located in the spaces between the incisors (or canines if the horse has them) and the premolars of the horse's mandible. The bit generally rests on the parts of the horse's gum covering the mandibular bars. The bit is installed in the horse's mouth so as to allow relative movements of the bit with respect to the mandibular bars, which causes friction that injures the horse's gums.

[0120] As illustrated in Figures 1-5, the guard 1 comprises two side portions 5a, 5b which are symmetrical. Each side portion comprises a respective inner holding portion 2a, 2b. Each inner holding portion 2a, 2b comprises a protective element 3a, 3b. The inner holding portions 2a, 2b are configured to be positioned in the mouth of a horse such that their protective elements 3a, 3b each protect a respective mandibular bar.

[0121] When the guard 1 is coupled to the horse's lower jaw, each of the guard members 3a, 3b covers and is supported by a respective mandibular bar of the horse. When the guard 1 is coupled to the horse's lower jaw, each of the guard members 3a, 3b extends along the respective mandibular bar between the incisor (or canine if the horse has one) and the premolar adjacent to the respective mandibular bar. In this way, the incisors (or canines if the horse has one) and the premolars adjacent to the mandibular bars limit the movements of the inner holding portions 2a, 2b forward and backward in the horse's mouth and contribute to the coupling of the guard 1 to the horse's mandible.

[0122] The shield also includes an outer holding portion 4 configured to be positioned outside the horse's mouth and against a posterior portion of the horse's head. In the shield illustrated in Figures 1-5, the outer holding portion 4 is configured to be positioned against the trough of the horse's head. When the shield 1 is coupled to the horse's lower jaw, the outer holding portion 4 is configured to be held against the trough of the horse's head by a strap of a bridle attached to the horse's head. The bridle thus limits the possible gap between the outer holding portion 4 and the posterior portion of the horse's head.

[0123] The outer holding portion 4 illustrated in Figures 1-7 comprises two symmetrical parts and each comprising a respective rear head contact surface 8a, 8b for contacting the horse's trough. The rear head contact surfaces 8a, 8b are concave to at least partially conform to the rear of the horse's head. This reduces the movements of the outer holding portion 4 relative to the horse's trough and in the lateral direction of the horse's head. In this way, the outer holding portion 4 contributes to the coupling of the protection 1 to the horse's head.

[0124] The outer holding portion 4 is configured such that the rear head contact surfaces 8a, 8b are in contact with the rear head of the horse when the guard is coupled to the mandible of said horse. Preferably, the external surfaces are covered with soft or flexible material so as to better fit the posterior part of the horse's head. This also limits friction between the posterior part and the external holding portion 4.

[0125] The inner holding portions 2a, 2b and the outer holding portion 4 of the shield are configured to allow coupling of the shield to the mandible of the horse. Preferably, such coupling further comprises holding the outer holding portion 4 against the posterior part of the horse's head by a strap of a bridle attached to the horse's head, as illustrated in Figure 13. The shield coupled to the horse's lower jaw means that the shield is attached to the horse's lower jaw so as to follow the movements thereof.

[0126] Each inner holding portion 2a, 2b is mechanically coupled to the outer holding portion 4 through a respective joining portion 6a, 6b. In the shield illustrated in Figures 1-7 and 13, the joining portions are symmetrical about a plane of symmetry S of the shield 1, and are arched so as to go around the lower jaw of the horse on each side thereof. When the shield 1 is coupled to the lower jaw of the horse, each joining portion 6a, 6b therefore provides a mechanical coupling between a respective inner holding portion 2a, 2b positioned in the mouth of the horse and the outer holding portion 4 positioned outside the mouth of the horse.Preferably, the joining portions 6a, 6b are configured to mechanically couple the inner and outer holding portions rigidly, i.e. without allowing relative movements between the inner and outer holding portions other than those caused by plastic deformation of the materials constituting the protection.

[0127] In the guard 1 shown in Figures 1-7, the guard members 3a, 3b are removable from the inner holding portions 2a, 2b. As shown in Figures 6-7, the inner holding portions 2a, 2b each include a coupling portion 7a, 7b for enabling coupling with one of the guard members 3a, 3b. The guard members 3a, 3b are configured to be detachably coupled to the inner holding portions 2a, 2b. internal supports 2a, 2b. It is therefore possible to replace the protective elements 3a, 3b of the protection depending on the sensitivity of the horse, for example by using protective elements 3a, 3b made of materials of different hardnesses. Protective elements 3a, 3b that are more or less soft can, for example, be used on a horse whose gums of the mandibular bars are more or less sensitive, respectively.

[0128] It is also possible to replace the protective elements 3a, 3b of the protection depending on their wear.

[0129] It is also possible to replace the protective elements 3a, 3b of the guard depending on the length of the mandibular bar. This means that protective elements of different dimensions can be mounted on the guard to adapt to different distances between the incisors (or canines if the horse has them) and the premolars of a horse, for example. This allows the same guard to be used with horses with very different mandibular bar lengths, by replacing only the protective elements.

[0130] For example, the protective elements 3a, 3b may be coupled to the inner holding portions 2a, 2b by threading, gluing, screwing, or other mechanical coupling means, preferably rigidly.

[0131] In the protection 1 shown in Figures 1-7, the outer holding portion 4, the two joining portions 6a, 6b, and the coupling portions 7a, 7b are in one piece. In this way, they can be manufactured to form a single piece.

[0132] According to a second aspect, the invention relates to a method for attaching a mandibular bar gum shield to the mandible of a horse. The shield is for example grasped by the joining portions 6a, 6b by a person. Then, the inner holding portions 2a, 2b are inserted into the horse's mouth so that each shield member 3a, 3b covers a respective mandibular bar of the horse, and the outer holding portion 4 is positioned outside the horse's mouth against the horse's trough. Each inner holding portion 2a, 2b comprising a shield member 3a, 3b is positioned on a mandibular bar respective, between the incisor (or the canine if the horse has one) and the premolar adjacent to the respective mandibular bar. The outer holding portion 4 is inserted between a strap of a bridle attached to the horse's head and the horse's trough so as to limit the gap between the outer holding portion 4 and the trough. Preferably, the bridle is arranged so as to maintain contact between the outer holding portion 4 and the trough.

[0133] Figures 8 and 9 show a preferred embodiment of the protection according to the invention in which the bridle contact surface 14 comprises protrusions 13 to prevent movement of the bridle or a bridle strap along the contact surface 14. This improves the retention of the outer holding portion 4 relative to the lower jaw 101 of the horse, because the outer holding portion cannot slide past the bridle strap 105.

[0134] As illustrated in Figures 1 and 8, the protection 1 according to the invention may comprise a transverse plane P. As illustrated in Figure 8, the transverse plane P separates the gingival contact face(s) 15 from the contact surface(s) 8a, 8b of the posterior head portion of the protection. The gingival contact surface(s) 15 are oriented towards a first face of the transverse plane. The contact surface(s) 8a, 8b of the posterior head portion are oriented towards a second face of the transverse plane opposite the first face of the transverse plane.

[0135] Such a configuration prevents upward and downward movement of the guard relative to the horse's mandible. As illustrated in Figure 13, when the guard is coupled to the horse's head: - the gingival contact faces 15 prevent downward movement of the guard, i.e. towards the rear part of the horse's head, - the rear part head contact surfaces 8a, 8b prevent upward movement of the guard.

[0136] Preferably, the transverse plane is orthogonal to the plane of symmetry of the protection.

[0137] According to the third aspect, the invention relates to a method for protecting a horse's gum. The method comprises the steps of: - at least partially covering a mandibular bar in the horse's mouth with a protective element, - positioning the outer holding portion outside the horse's mouth against a posterior portion of the horse's head, - positioning a joining portion mechanically coupling the protective element to the outer holding portion such that, when the protective element at least partially covers the mandibular bar and the outer holding portion is positioned outside the horse's mouth against the posterior portion of the horse's head, the joining portion bypasses the horse's lower jaw.

[0138] In the method, the joining portion is preferably positioned to at least partially, and not entirely, contour the horse's lower jaw.

[0139] In summary, the invention can also be described as follows. Protection 1 for a horse mandibular bar comprising: - an inner holding portion 2a, 2b for being positioned in a mouth of a horse, preferably relative to a mandibular bar of the horse, and comprising a protective element 3a, 3b; - an outer holding portion 4 for being positioned outside the mouth of the horse in contact with a posterior part 103 of a head of the horse;

[0140] The guard is configured to be attached to a mandible of the horse when: - the inner holding portion 2a, 2b is positioned in the horse's mouth such that the protective element 3a, 3b prevents direct contact between the mandibular bar and a bit installed in the horse's mouth, - the outer holding portion 4 is positioned outside the horse's mouth and in contact with the posterior portion 103 of the horse's head, the outer holding portion preferably being held in contact with the posterior portion of the horse's head by a strap of a bridle attached to the horse's head.

[0141] The invention therefore relates to a mouth guard which is positioned at the point of action of the horse's mouthpiece, i.e. the bit. Intended to control the horse. This protection aims to protect the gum from the action of the bit and therefore prevent any hypersensitivity and injury in the horse's mouth. This therefore improves its well-being as well as optimizing its sporting performance.

[0142] Figure 13 shows a protection according to the invention in the position of use, that is to say coupled to the lower jaw 101 of a horse's head 100. A bridle 105 is attached to the horse's head. The bit is not shown. When the bit is installed in the horse's mouth, between the two jaws, it is supported by the protective elements 3a, 3b covering the mandibular bars 104.

[0143] As illustrated in Figure 13, the outer holding portion 4 is positioned against the rear portion 103 of the horse's head. The outer holding portion 4 is further held against the rear portion 103 by means of a bridle 105. In this way, the coupling between the protection and the horse's mandible is maintained even when the horse shakes its head.

[0144] Joining portions 6a, 6b connect the outer holding portion 4 to the protective elements 3a, 3b.

[0145] Figures 10, 11, and 12 show views of protective elements 3a, 3b according to the invention. Each protective element comprises a main tab 9 for being brought into contact with and covering a respective mandibular bar 104. The main tab 9 extends along the X axis and in the direction of increase of X from a front end 9f to a rear end 9r of the main tab 9. When a protective element 9 covers a mandibular bar 104 of the horse as illustrated in Figure 13, the X axis is parallel to the length direction of the mandibular bar, and the gingival contact face (not visible in Figures 10-12) is in contact with the mandibular bar 104. In Figure 10, the face of the main tab 9 opposite the gingival contact face is visible.

[0146] Each protective element includes a housing 10 for receiving a rod 7a, 7b as shown in Figures 8-9. This allows the protective element to be coupled to a structure configured to hold it in the horse's mouth. The housing 10 extends along the X axis between first and second ends 10f, 10r of the housing. The first end 10f of the housing is provided with an opening visible in Figure 11 for inserting the rod. The second end 10r of the housing extends beyond the rear end 9r of the main tab 9.

[0147] To limit the lateral movements of the protective elements 3a, 3b relative to the horse's mouth, they each comprise a rim 11 as shown in Figure 12. The rim extends from the main tongue 9 in the decreasing direction of Z. In this way, the main tongue 9 and the rim 11 form an angle. Such a protective element makes it possible to at least partially surround the mandibular bar when it is installed in the horse's mouth. In particular, the rim 11 extends between the tongue and the lower jaw 101 of the horse when the protective element is positioned so as to at least partially cover the mandibular bar.

[0148] As illustrated in Figure 13, the main tab 9 prevents direct contact between a bit installed in the horse's mouth and the gum of the mandibular bar 104.

[0149] As illustrated in Figure 13, the protective element can further also serve to protect the premolar 106 adjacent to the mandibular bar 104. For this, the protective element further comprises a flap 12 as illustrated in Figures 10-13. The flap 12 has a joining edge 12a attached to the rear end 9r of the main tab 9, and a free edge 12b opposite the joining edge. The flap 12 is orientable relative to the main tab 9. For example, as illustrated in Figures 10-12, the flap 12 extends mainly along the X axis and in the extension of the main tab when it is in the rest position. As illustrated in Figure 13, when the protective element 3a, 3b is positioned in the horse's mouth so that the main tab 9 covers the mandibular bar, the flap 12 is in a folded position relative to the main tab 9 and rests on the premolar 106 adjacent to the mandibular bar.In such a position of use, the flap extends mainly along the Z axis. Along the Z axis, the free edge 12b is then located opposite the rim 11 relative to the main tab 9.

[0150] In Figure 13, only the horse's lower jaw is shown. The tongue, cheek, and upper jaw are not shown.
