[0065] FIG. 8 is a rear view of the second embodiment of the boot showing fitting of the boot in ghost lines with the pastern strap omitted for clarity.

[0066] FIG. 9 is a bottom view of the second embodiment of the boot.

[0067] As seen in FIGS. 1 and 4, a first embodiment of the boot 10 comprises ground engaging sole member 30, retaining means 50 comprising boot upper 52 and strap 60, with ventral portion 51a located towards the front of boot and dorsal portion 51b located at the rear. The open character of boot 10 helps to provide a light weight boot.

[0068] Sole member 30 which forms the bottom of the boot comprises sole plate 32 with interior surface 36 and external surface 37 (FIG. 2). Interior surface 36 is suitable for seating the ground bearing portion or rim of hoof 100. Exterior surface 37 has a suitable tread. Sole member 30 may be constructed of various materials but the preferred material is TPU (thermoplastic polyurethane) which is a very hard wearing material suitable for the 30 abrasive nature of a moving horse on its foot wear. TPU utilized may be of appropriate rigidity such as 95 Shore A hardness or 60 or 65 Shore D hardness. Boot upper 52 may be made of stiff leather or other suitable material and joined to sole member 30 by means of stitching.

[0069] Upwardly depending sidewalls 35a and 35b of sole member 30 are sloped to mimic the angle of hoof wall 120 (FIG. 3). Although these are shown as continuous walls of constant cross section in the drawings it is envisaged that sidewalls 35a and 35b may be pleated, fringed or fluted to accommodate the different hoof wall anatomy of individual horses (some horses have very steep hoof walls while other has very sloped 40 walls). Notably sidewalls 35a and 35b do not extend all the way around to heel 130 of hoof 100 providing a substantially open rear of boot 100 (FIG. 4).

[0070] Retaining means 50 comprises boot upper 52 with inside 52a and outside 52b. Boot upper 52 includes webs 53a and 53b which extend from the tops of sidewalls 35a 45 and 35b up to collar 56. Webs 53 comprise two pairs of legs 54 (one pair at the front and one pair at the back) which define side vents 55. Side vents 55 provide air circulation and a means of escape for debris collected by the boot. Front opening 57 adjacent webs 53a and 53b extends from collar 56 at the top of boot 10 all the way to the level of interior surface 36 in sole plate 32.

[0071] Bulb engaging means 70 comprises shank 72, rear legs of pair 54 and apertures 5 58a and 58b at the back of boot 10. Shank 72 is advantageously half round in cross section as shown in FIG. 2. Shank 72 runs from sole plate 32 to collar 56. Bulb engaging means 70 is fixed in relation to sole member 30 and unlike the Lander boot of the prior art does not pivot.

[0072] When fitted, boot 10 snugly conforms to horse hoof 100. Collar 56 fits just on or above coronary band 110 of the hoof which is the area of the hoof where the hair on the horse's leg meets the smooth solid hoof wall 120. Boot 10 is in an open condition when strap 60 is unfastened. Front opening 57 allows boot 10 in the open condition to be opened up entirely to allow easy application of hoof 100 into the boot. Front opening 57 may be from 2 to 50 mm in width, preferably from 30 to 50 mm in width.

[0073] A tension snap lock comprising strap 60 and grips is used to secure the front two sides of the upper portion of boot 10 bring about the closed condition. Once hoof 100 is placed into boot 10 then the snap lock pulls the two front edges (webs 53a and 53b) of upper portion 52 together securing the front of the boot and ensuring the hoof is securely contained inside the boot. A tension snap lock is the preferred means for the securing and closure system but other forms of closure can be used such as buckles and the like.

[0074] Boot 210 (shown in FIGS. 5 to 9) is shallower in depth and simpler in construction than the first embodiment. Thermoplastic urethane (TPU), a durable, relatively rigid or non-deformable material is injection moulded to form sole member 230 and shell 252 as a unitary piece. The TPU used has an appropriate hardness value such as 95 Shore A hardness, 60 or 65 Shore D hardness or other suitable hardness. In this embodiment retaining means 250 comprises shell 252, front straps 260 and security strap 280. Straps 260 and strap 280 are also made of TPU. Strap 280 wraps around the upper pastern of the horse and provides an extra tether.

[0075] Sole member 230 comprises interior surface 236 and exterior surface 237 (FIG. 7c) with frog support 240 and has an appropriate tread in the area that corresponds to the wall of the hoof (FIG. 9). Viewed from below sole plate 230 is a distorted ‘0’ shape with a broader dorsal region and an opposite blunted ventral end mimicking the basic shape of the sole of a hoof.

[0076] Shell 252 has ventral portion 251a and dorsal portion 251b and comprises side walls 253 and bulb engaging means 270 which extend upwardly from sole member 230.

[0077] Sidewalls 253 extend from front flaps 253a and 253b around to rear legs 254 with side vents 255.

[0078] Front opening 257 sits between front flaps 253a and b with lateral slits 257a and 257b above sole member 230. Each strap 260 is riveted at one end to front flap 253b and has appropriate apertures at the other end to allow fastening to knob hooks mounted on front flap 253a adjacent front opening 257. Lugs 259 located above and below straps 260 help protect the straps from wear.

[0079] Upper edge 256 sits below hairline at the front of hoof 100 as there is no collar in this embodiment. Upper edge 256 of sidewalls 253 is curved upwards into arches 256a and 256b at rear of boot. Security strap 280 is removably attached to arch 256a with a stud at one end and, at the opposite end has appropriate apertures to engage with knob hooks on arch 256b at the rear of boot 210.

[0080] Dorsal portion 251b is substantially open due to apertures 258a and 258b. Bulb engaging means 270 is provided by arches 256a and b, rear legs 254 and shank 272 which runs between upper edge 256 and sole member 230.

[0081] Apertures 258a and 258b are ovoid in shape and design be seated around the periphery of bulbs 135 when boot 210 is fitted.

[0082] Bulb engaging means 270 is essentially ‘m’ shaped and is particularly suited to engaging the periphery of the bulbs.

[0083] The open rear of the boot and the enclosed ventral portion causes the bulbs to be pushed out of the open back of boot 210 and forced into bulb engaging means 270 providing a fit akin to a form fit or a friction fit.

[0084] Although in the embodiment illustrated the dorsal portion of the boot is open, it is contemplated that the dorsal portion could be covered by a soft or pliable material such as a mesh or netting (i.e. a material which would not put any effective pressure on the cups of the bulbs) which would still allow the bulbs to be pushed back against the bulb engaging means 270.

[0085] While the prior art requires the periphery of the sole member and upper portions of the sole member to conform as closely as possible to the shape of the horse's hoof wall to minimize movement of the hoof within the boot, embodiments of the present invention provide a more versatile fit. This is because the inventor utilizes the bulbs to provide anchoring.

[0086] The rear of boot 10, 210 is an important feature of embodiments of this invention. The rear of boot 10, 210 has dorsal portion 51b, 251b which is open, or substantially open around heel of hoof 130. The open heel allows bulbs 135 of hoof 100 to be accommodated on the outside of boot 10, 210 rather than inside the boot which is the practice of traditional hoof boots. Bulbs 135 of the hoof 100 are anchored by shank 72, 272. This shape of the rear of the boot moulds to the shape of bulbs 135 and locks the bulbs into this area of the boot which prevents the boot from moving backwards and forwards and from rotating on the hoof. At the same time shank 72 and collar 56 or shank 272 and curved member in the form of upper edge 256 prevent the boot pulling downwards preventing sole member 30, 230 from losing contact with the sole of the hoof. This combination of features locks the bulbs firmly into the rear of the boot, prevents the boot rotating and separating from the sole of the hoof. Specifically the shank lies over the cleft in the dorsal part of the bulbs and this is the feature which prevents the boot moving away from the heels of the hoof. The shank which engages the cleft of the bulbs is combined with an upper which is either a collar or a curved member which lays over the upper dorsal part of the bulbs and extends down the lateral sides of the bulbs. These associated lateral structures are what prevent the boot rotating by “capturing” or gripping the peripheries of the bulbs but do not put any effective pressure on the cups of the bulbs. These functions provide ultimate security not achieved with prior art hoof boots.

Example 1: Construction of the Boot

[0087] A person skilled in the art will be familiar with the materials and construction methods employed to make a hoof boot, for example those disclosed in the prior art discussed earlier.

[0088] In the second embodiment, shell 252 and sole member 230 of boot 210 is produced by an injection moulding process making it an integral one piece construction. TPU of 60 Shore D hardness by Bayer(E′ is injected into the mould, left for an appropriate time to harden and then removed. Separate straps made of TPU of an appropriate hardness are attached onto shell 252.

[0089] It is envisaged that the boot will be made in a number of different sizes to cover the range of most hooves. Boots start at size 4 (135 mm wide by 130 mm long). Hoof size is determined by measuring the front of the toe straight over the middle of the frog down to the buttress of the heel (being the furthest part of the ground bearing area of the hoof).

[0090] Further it is envisaged that the boot shell may be produced by laser sintering techniques using suitable TPU or other materials.

[0091] Although modifications and changes maybe suggested by those skilled in the art, it is the intention of the applicant to embody within the patent warranted hereon all changes and modifications as reasonably and probably come within the scope of this contribution to the art. The features of the present invention which are believed to be novel are set forth in detail in the appended claims. The features disclosed in the description, the figures as well as the claims could be essential alone or in every combination for the realization of the invention in its different embodiments.

[0092] Throughout this specification and the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of a stated integer or step or group 35 of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
