Abstract

Shoes which by their construction avoid twisting stress which save especially the knees of humans and lower legs of horses from serious injury are shoes which are equipped with “Turn-Table” topped outsold disc treads of simple anti-friction design upon which top surface said shoes can rotate on to any 360 degree direction while said outsole bottom surface tread is frictionally adhered to a footing surface with said shoe outsole discs that resist any linear free wheeling motion or footing slippage even when said shoe is substantially tilted to a rapid action canted positional arrangement with a footing surface due to substantial disc perimeter tread flexibility.

Description

Sir:

Be it known that John Robert Manis, whose residence is 17320 Meridian Blvd., Township of Hudson, County of Pasco, State of Florida 34667-4937 and a citizen of the United States of America has invented new and useful shoe Static Outsole Structures connection to Rotary Midsole Structures disclosed previously in my full provisional patent application having 22 drawing figures filed in the United States Patent and Trademark Office on Oct. 27, 2003 given provisional patent application filing No.-60/514,778, and further having filed a second nearly identical copy of the same invention in which some small errors were corrected and which said second said full provisional application had with it an identical set of twenty two drawings which were identical to the set of 22 drawings filed with the first said provisional application. The second said full provisional application received the same filing date of Oct. 27, 2003 as the said first provisional application with the said second full provisional application given the filing No. 60/514778 and of which I prefer claiming said Provisional Patent application filing date thereof Oct. 27, 2003 I claim as the filing date for this Patent Application which specification discloses no new subject matter and pray that Letters Patent be allowed and issued for this said Patent Application of which the USPO had responded to earlier and dismissed the claimed filing date of the above identified provisional applications filed on Oct. 27, 2003 due to the entire set of 22 drawing figures not having accompanied said provisional application specification they referred to numerically and of certain language also thereto nor did my declaration as the sole inventor of said above identified patent application. As to this action of the USPO I was further informed that the only patent application filing date that would be recognized for my above identified invention would be the date upon which my answer to the USPTO above action was received in the USPO without benefit of any advice given the pro ce applicants' right to respond Therefore I would respectfully say that I the pro ce inventor did all of the work of first envisioning the invention and then every bit of all of the work of drafting all of the drawings and all of the language of the specification, and all claims first informally and then formally for filing in the USPTO having brought the full patent application myself to my little rural USPS building where in my rush to get the application out into the mails for that day which was my deadline day for filing my application to receiving the filing date of my said provisional applications I wanted to be absolutely sure that I had inserted all of the necessary papers of my patent application into my mailing envelope and therefore I asked the Postmaster Joseph LaFranca at the counter of the Aripeka, Fla. Post Office branch 727-868-6876 to give me a few moments to take out all of my patent applications' papers to make sure all necessary papers were in my mailing envelope which the said postmaster allowed time to do and after seeing that all said application papers were present and in order I put them all back into my mailing envelope but which now I could not get the envelopes' adhesive coated flap to seal closed at which time I requested that the postmaster send my envelope to the USPTO via Overnight Express Mail. At which time the postmaster said that I need not worry that my original mailing envelop would not seal because he was going to put my said envelop into a separate very strong Express Mail Envelope then calculated my postage which I paid and received a receipt for and left the Post Office building while Postmaster Joseph Lafranca was still in the process of putting my unsealed patent application mailing envelope into the said other overnight Express Mail Envelope. Later when I received a response from the USPTO that the said application was received at the USPTO without the applications required drawings and with other required documents missing also On those grounds the USPTO denied my right to claim the filing date of the said patents' earlier filed said provisional application and and informed me that I would not receive a filing date for my patent until all necessary drawings were properly filed in the USPTO and payment of all USPO fees were paid but then I would not receive my earlier filed provisional applications' filing date but just a leter date at the time said drawing were received and said fees paid which actually would not benefit me any more than more simply refiling said regular patent application. Not understanding how it was possible that my said patent application drawings which I double checked on and saw and mailed at the said Aripeka Post Office had not been received by the USPTO Therefore I went back to said post office and informed Postmaster Joseph Lafranka of the notice from the USPTO of missing drawings and other papers from my said application he mailed for me that arrived at the USPTO. The postmaster then said that he did recall that I had inspected all of my said patent application papers to make sure all necessary parts were there ready for mailing including the drawings of which I am sure as the postmaster admitted the to being only a foot away from the applicant when he checked out the application papers directly in front of him got a good glimpse of the 22 patent drawing figues I had spread out as just mentioned directly in front of him and so therefore I asked the Postmaster if he would kindly write a note for me to give to the USPTO that he the postmaster had witnessed that the applicant had made said inspection of his patent application before mailing it which the postmaster did write in said note and gave it to the applicant of which a copy of said note is attached to this present substitute now double spaced application which has no new subject matter I had earlier sent as aforementioned. I am 73 year old and not in the best of health having gotten over and still recovering from a number of illnesses including a urinal bladder infection which have caused unavoidable delays in getting all of this various legal paperwork for the USPTO in proper order as a pro se applicant who has no one to turn to who is knowledgeable for help in these matter and wishes that the USPTO will change its position and allow the applicant the filing date of his earlier filed provisional patent application for his identical present regular patent application which the applicant prays for an early decision on this matter because of the applicants missing drawings and the possibility of someone not the inventor attempting to file a patent application from unique information that may be seen by anyone carefully inspecting my lost patent drawings which have been lost now for quite a long time. Therefore I respectfully request PTO assistance in the filing and prosecution of this my pro se application for letters patent

FIELD OF THE INVENTION

The invention relates to shoes, and more particularly to shoe soles construction.

BACKGROUND OF THE INVENTION

There have been many advances made in designing cushioned “non-slip” outsole structures to make sure that a shoe will not slip on a footing surface especially with sport shoe design. But what has not been realized with these said advances is that by increasing greater frictional adhesiveness traction for a shoe's outsole greater becomes the force and physical stress of a shoe wearer to break free said shoe's outsole from a footing surface, gravitated to, especially when said shoe wearer must make an in place shoe turn with one shoe with the fall weight of said shoe wearer gravitating down on said shoe's “non-slip” outsole. Shoes generally right up to present times do not provide for substantial free turning of a shoe when the weight of said shoe wearers body causes said “non-slip’ outsole to be frictionally adhered to a footing surface, especially as concerns the forefoot region leverage of said outsole. And although there have been advances in the construction quality and function of the insole, and outsole; quality advances have not been developed to allow the upper shoe to operate correctly to turn either clockwise or counter clockwise to any point of 360 degrees while said shoe's outsole remains frictionally adhered in one position at a footing surface by the weight of the shoe wearer Also prior art does not show development of increasing footing surface contact of a shoe's canted outsole position which said outsole has only a small outer edges surface remaining in contact to a footing surface which then often fails to prevent slippage for a shoe wearer.
What is true within the discourse of the above specification as concerns physically stressful human activity caused by said shoes; is also true for certain domestic animals when these animals are forced to walk upon unnatural man made surfaces such as rough concrete with footgear not folly developed to enable an animal to do so safely as is exemplified in this specification concerning horse's horseshoes designed to have “proper” traction which can become snagged to certain man made surfaces and cause twisting stress injuries of a horse's leg tendons and ligaments. It is known that horses often are suddenly excited into a frenzy of sudden physical activity in resistance to being handled by their human caretakers. And when these exacerbated excited leg movements occur on man made surfaces such as on hard rough non-slip concrete surfaces that are common surfaces for the floors of horse stables; then these said sudden leg movements are apt to strain the horse's legs via the turning resistance of a horse's hoofs on horseshoes which often snag on such said rough surfaces of concrete floors and also on other man made surfaces. Such stressful horse activity, especially when repeated over and over again often causes leg injuries which recognizance of the source of is seldom recognized by horse owners and horse handlers.
The applicant has studied movies of movements of horses and researched the diagnostic protocol for degenerative suspensory ligament desmitis DLSD of horses lower legs. A disease found in all breeds of horses. Accept for one breed, DSLD almost always occurs in BOTH HIND LEGS of a horse NEVER IN JUST ONE bind LEG and almost never to the front legs. The cause of this wide spread disease is not really known, only speculated and theorized on by veterinarians.
After conducting research on the subject in length the applicant has come to a philosophical view of at least one cause of this disease in all breeds of horses and which applicant feels is likely to be the principle cause. The ligament and tendon connections to the bones and muscles of the hone's lower legs which keep the joints of bones and muscles in place are strong and resilient when working healthfully in normal ways with the muscles to work the normal joint action of the bones; but work the hardest when in an unhealthful manner resist abnormal twist forces occurring to the legs of the horse. The bone joints of the lower leg of the horse are held very strongly together by ligaments and tendons to resist said twisting forces to keep such bones as the small navicular bone in place which the muscles and joints of the horse's legs are designed by natures to be able to work to do so to only a ceratin very limited degree without strain when resisting diagonal twisting forces acting on the anatomy of said legs.
The applicant in viewing movements of horses has noticed on every occasion that when a horse is forced by a rider or ground handler to make abnormally sharp turns with its front legs, and even with not so sharp turns, each of the horses hind leg hoofs of the horse remain in place on a footing surface twisting around sliding in place to follow the pulling direction of the stepping front legs of the horse pulling its body around into said turn. This is a very abnormal movement for a horse to take and occurs only when the horse is being handled to do so. As seen in rodeo horse actions, the hind legs will stay in place this way even when a horse is forced to thrust Bill strength into tight barrel turns sometimes with the hone's front legs jumping the front body wildly high into such turns which fortunately occurs on the natural soft surface of mother oath but nevertheless it can be seen that the rear legs are much more highly stressed by twisting forces occurring at the hind hoofs than are the front legs of the horse at its front hoofs which are almost always raised off of a rooting surface one at time in stepping motions to initiate and move into said such tight turning movements, while, as mentioned, the rear hoofs usually remain in their original standing positions on said footing surface upon initiation of said turns in order to Billy support the hone by simply twisting around with hind feet hoofs in place into rotational sliding motions on said footing surface. And there is a lot of evidence that horses lower legs are not very sensitive to pain and therefor can be stressed quite often but the horse not reacting stressfully when forced to make such turns which the applicant believes, along with shod hoof snagging to be the principle causes of DS

SUMMARY OF THE INVENTION

It is with these problems in mind that the applicant's invention was developed. The invention may be characterized as a shoe sole constriction comprising a midsole layer, an outsole layer and outsole/sole disk part including an intermediate region attached to said midsole and outsold/sole disk parts comprising a sole disk installation structure part upon which an upper shoe is attached to has the potential to rotate upon disposed immediately above and attached rotationally to said outsole/sole disk part when said outsole/sole disk part is at a static positional arrangement on a toting surface and to said rotational sole disk Installation structure. A sole disk installation structure may be comprised of a resiliently flexible hollow outer shell wall defining an interior chamber The said shell may also be comprised of a thermoplastic elastomer or composite graphite materials and said shell having a circular opening to which perimeter of said opening the said outsole/sole disk part is attached to that closes and seals said opening. Said outsole/sole disk will herein after be referred to in remainder of the specification simply as sole disk or soledisk.
And on said sole disk pail said outer shell of said sole disk Installation structure attached to upper shoe's midsole may rotate on. An inner filler may be encapsulated within said shell's interior chamber. Or only said sole disk Installation structure shell's resiliently flexible wail may function alone with its said chamber not substance filled nor air tight to work in resiliently flexible downward unfolding and upward folding and canted positional reconfigurational arrangement functions to its attached sole disk while bottom surface of said sole disk is kept folly in contact to a footing surface while upper shoe remains in a canted positional arrangement to said sole disk. The Mid sole disk may have a rigid upper layer attachment structure and a bottom surface integrally adhered to a bottom outsole layer of any kind of suitable configuration of softer material designed for adequate traction to a footing surface. The said sole disk ached to said sole disk Installation structure's resiliently flexible shell chamber wall provides cushioning from shock to the shoe when its outsole is impacting onto a footing surface by the shoe wearer even when said shoe is in a canted position to and impacting said surface.
Another embodiment of shoe sole construction of the invention comprises features where the sole disk material is resiliently flexible at and inward from the tapered region of its perimeter, and said sole disk is attached directly to a rotatable intermediate sole disk attachment structure of the shoe. Said resiliently flexible tapered region inward from the perimeter of said sole disk remains in contact with a footing surface when the shoe is at a canted configuration to a toting surface.
With either embodiment of shoe sole construction the midsole may extend downward to become an outsole align between a heel sole disk and a forefoot sole disk and arranged at least one quarter inch circumferentially rearward of a forefoot region sole disk and at least one quarter inch circumferentially forward of a heel region sole disk.
Then “outsole” may be applied to either a heel disk sole or a forefoot disk sole and “outsole” also applied to the intermediate region between said heel disk sole and said forefoot disk sole which said outsole region extends to the same bottom surface level as said sole disks mentioned which distinction will always be disclosed evidently within the discourse of the following specification. The word “shoe” as mentioned above may be applied as that which is worn by humans or animals such as then “horseshoe” implies but the word “shoe” can also be construed to the meaning of the word “gear” that is used in then “animal leg gear” for the hoof or paw of an animal. The meaning of these said terms will be apparent as they are applied either to humans or animals.
A said sole disk of any embodiment above or below may have the sole disk outsole bottom footing surface made of a variety of materials of various bottom configurations either in the form of a one piece solid sole disk or said outsole of said sole disk as a separate layer adhered and/or sewn to the sole disk main body and cleats or spikes may be added to said outsole such as cleats for said outsole of said sole disk for football shoes, and spikes for said outsole of sole disks for golfers shoe. Which said shoes will prevent injury and increase the agility of the shoe wearer.
The invention further includes an alternate embodiment to accommodate dress shoe soles made frown flat sheet stock of lather signed to accommodate the structure of a horse's hoofs.
For the best reliable rotational functions within said embodiments of the invention it is preferable that portions oldie midsole, outsole and the upper surface of disk soles upon and at which a shoe rotates are made of internally lubricated rubber or thermoplastic elastomer materials that have lubricating substances bound within said materials which do not require maintenance nor said lubricant significantly nib off onto other parts.
There are a variety of techniques to lower fiction of a rubber pan. A rubber can be formulated specifically for lower friction by using certain types of low friction ingredients. Coatings such as FIFE-based coatings, or surface treatments, such as Minnesota Rubber's F-Treat Process, are other methods to reduce part friction.
A unique method used by Minnesota Rubber to provide fiction reduction is by the addition of lubricants into the elastomer mixture. These chemicals modi˜'the surface of the part to provide an “internally lubricated” compound. The presence of the lubricant does not effect the physical properties of the rubber part. The internally lubricated compounds are designed for intermittent or slow cycling type application. re: as applies to upper sole disks and sole disk installation structures and various said other parts of this invention that feature maintenance free lubricated parts.
It is noted here that because a sole disk and sole disk attachment structure allows free turning of the upper shoe without turning of said sole disk fictionally adhered to a footing surface, said sole disk's bottom surface wear at said footing surface should be markedly reduced when compared to frictional abrasive wear of the integral fixed placement of soles of conventional shoes when the shoe wearer makes forced in place turns required to break a surface's frictional hold on the outsole sole bottom to slide it around on said surfaces which action causes substantial frictional wearing of said conventional outsole.
The shoe disk soles of this invention provide linear fraction and said shoe cm only rotate either on a heel sole disk or a forefoot sole disk when the shoe wearer lifts either the shoe's forefoot region or heel region off of a footing surface therefor leaving only a heel sole disk or a forefoot sole disk on said footing surface to rotate on.
The invention also provides tractional resistance to all movement of a shoe including full resistence to linear and turning movements when said heel and forefoot disk soles are both in contact with a footing surface which therefor also includes the intermediate region of the shoe's outsole also in contact with said footing surface between said heel and forefoot region disk soles.

OBJECTS OF THE INVENTION

The object of the invention is to construct a shoe for humans and/or for animal hoof and paw shoe gear that allows shoes to rotate freely upon a fixed position of said shoe's outsole upper surface structure while said outsoles's bottom surface is frictionally held to a fixed position on a footing surface by weight of the shoe wearer either at the forefoot region of the shoe with said shoe's heel and intermediate outsole are raised off said surface, or the heel region at a fixed position with the said shoe's forefoot region and intermediate outsole are raised off of said surface. The shoe wearer is therefor able to freely rotate in place either on said shoe's heel region or forefoot region to any 360 degree point of direction, either clockwise or counterclockwise, in one and/or the other of an upper shoe's rotatable midsole structure turning on and attached to the complemental fixed integral structure of shoe's said outsole of this invention held to a footing surface accomplished to reduce to a high degree twisting force stress of the ligaments and tendons of the muscles and joints of the shoe wearer being beneficial to both humans or animals alike, especially when engaged in high stress physical activities, and also beneficial for the infirm or elderly, and for those recovering from foot; hoof or paw and/or leg and hip injuries or diseases or the said shoes or animal gear may be employed for use to simply reduce lower body stress to maintain good foot leg and hip joint health.
Another object is to allow shoes equipped with said sole disks of the invention to remain to have full fractional resistance to any shoe movements when said sole disk equipped shoes heel and/or midfoot and forefoot regions remain together in frictional contact with a footing surface.
A further object is to provide shoes with disk shaped outsoles that will allow the shoe wearer to make body turns much more quickly and with less effort and stress with said shoes that can make turns on said disk shaped outsoles which remain in a static footing position which actions cannot be accomplished with conventional shoes having integral outsoles fixed in place to a shoe bottom.
Another object is to employ a shoe sole in the form of a disk upon which a shoe for humans or animal hoofed paw shoe gear can rotate on to any desired point of 360 degrees clockwise or counterclockwise and which said sole disk when brought to a canted position automatically locks in place and will not rotate on sole disk rim flexibly maintaining a substantial canted angular inward sole disk bottom surface contact with a footing surface.
A further object is to furnish said sole disk with a resiliently flexible perimeter employed to maintain a substantial angularly adhered sole disk undersole surface contact to a footing surface to prevent sole slippage when a shoe is raised to most any canted configuration from said footing surface.
Another object is to employ said sole disc upon which a shoe can rotate and also greatly absorb an impact force when said sole disk is moving downward at either a tilted or full parallel configuration to a footing surface, and which said force of impact energy is substantially absorbed away from the foot of the shoe wearer.
A further object is to employ said sole disk in a manner by which said sole disk can easily be removed and a replacement sole disk easily installed which disk may be either identical to the said sole disk previously removed or the sole disk outsole surface contact region may have variously different shaped structures made of various kinds of other materials to meet and serve other various activities and/or footing surface conditions requirements of said shoe's outsole footing surface contact structure.
Another objective is to correct and prevent the cause of most outsole wear which is caused by the conventional outsole sliding about on a surface by a shoe wearer wearing conventional shoes which have outsoles adhered at a fixed position onto the upper shoe of said shoe wearer, which said fixed outsole must overcome high frictional resistance to slide about into a turn on a surface by force of the shoe wearer's upper body twisting about to new directions causing substantial frictional wear to the shoe's said outsoles; which said new rotatable disk soles of this invention prevents and substantially reduces disk sole outsole bottom surface wear.
A particular object is to shod horses with horseshoes having features of this invention which allow fill and complete hoof wall flexibility.
Other objectives will be brought out or be apparent within the course of the following disclosure of the construction, arrangement and combination of elements as fully described hereafter and later pointed out in the claims forming a part of the specification.

Referring now to FIGS. 8, 9 and 10 enlarged for sake of clarity of reference to drawing details. All structural lines of said drawings define circular and straight complemental circular structures.
In general the function of said sole disk 16 attached to its sole disk attachment structure 1? such as shown in FIG. 2 is to preferably have structure 17 formed integrally fixed in place with a forefoot region or heel region of a shoe as an attached part or as a formed part of the rnidsole layer of the shoe and the sole disk thereto attached projecting downward to become a potentially free circle of rotation structure of the shoe outsoles topside structure of said disk sole that the shoe wearer can rotate a full 360 degrees on as required to any point thereof via circular structures 26, 27, 23 and 29 as clearly illustrated within the unhatched region of the enlarged drawing of FIG. 9.
More specifically a shoe wearer can rotate ones shoes while maintaining a fixed axial positions of rotation with a fixed linear position of said sole dislc4 which sole disk is fictionally adhesively established fixed in place at a footing surface where said shoe wearer may rotate at by weight of the shoe wearer bearing down on the non-slip undersurface of the said special outsoles sole disk 16 or 16A upon which said shoe wearer rotates on via the shoe's rotary sole disk attachment structure rotatably connected to and on said sole disks upper surfaces 32 and 47 complementarity configured to undersurface 48 end 49 of said sole disk attachment structure. Said structure 17 and 17A is held rotatable to said structure 16 and 16A by corresponding catch ring groove 27 and clasp ring 26. Said sole disk 16 and 16A is preferably made of fairly resiliently flexible materials such as the elastomer materials. And the sole disk attachment structure preferably made of fairly rigid internally lubricated materials such as ACETYL below. The alternate embodiment of a sole disk 32 and sole disk attachment structure 33 of FIGS. 3, 7 and 10 has a sole disk preferably also made of a fairly rigid internally lubricated plastic such as ACETYL made of components that are dimensionally stable even under extremely wet or humid conditions and will not swell. Additionally it resists most organic solvents and is easy to machine and does not burr easily. ACETYL is a genetic descriptive name for two polymers: Calcine—a copolymer made by Ceylonese—and DELRIN—a homopolymer made by E.L Dupont Nemours. Other internally lubricated plastics which are moldable may be used such as polyamide, polysulfate polyphenylene sulfide are high-temperature materials which may employ graphite as a bonded self-lubricating filler. To increase ease of manufacturing another material may be used for both the said sole disk and said sole disk attachment structure such—Ultrahigh-Molecular-weight Polyethylene which resists abrasion and has a smooth, low friction surface. And often an ideal material for parts commonly made from ACETYL or PTFE materials. PTFE has an exceptionally low coefficient of fiction and high self-lubricating characteristics. For use to make disk soles the said sole disk may be made up of several layers with a top layer preferably made up of pure Ultrahigh-Molecular-weight-Polyethylene or such materials, and a bottom layer of MILLATHANE used also for the intermediate outsole of FIG. 1 either homogeneously or for a combination of assembled parts. Cushioning material for midsole or insole can be constructed of Polyurethane (PU), Cellular ethyl acetate (EVA) or a combination of both of the thermoplastic elastomer Hytrel. A form of Hydrel of suitability is type HTX8177 available from E.l. Dupont de Nemours, Wilmington, Del.
In FIG. 7 the alternate embodiment of a soledisk 32 and sole disk attachment structure 33 of FIGS. 3, land 10 provides excellent cushioning and traction at a footing surface, even with the shoe in a canted five degree configuration, within and by means of the said structure's rigid sole disk working with the flexible resilient wail of the sole disk attachment structure, as at 36, enclosing a sealed air chamber 4? which provides cushioning by compression of said air trapped in the chamber 4? in combination with the resilient flexing of said wall 36 when a force is applied to said sole disk and which said wall 36 structure's memory resumes its former shape when said force is relieved. But in an alternate embodiment if said air chamber is not to be sealed and the air allowed to escape when a force is applied by having an opening in wall 36 then the wall 36 can be made of less resiliently flexible material and/or the said wall 36 can simply be made somewhat thicker to yield less easily to said applied force and/or the said air chamber 47 can be filled with a suitable foam material for being encapsulated within said chamber 47 such as PU, EVA or SURLYN injected into said chamber by any known method or any other suitable material may be employed to fill said chamber which chamber may be formed by blow molding, or injection molding as with other parts all being within the scope of this invention. And the specific gravity of said chamber wall 36 should be suitable to the specific gravity of a filler for said chamber which filler generally should have a said specific gravity less than that of the chamber wall 36. All of these said features, including allowing the shoe to freely turn even while either the outsoles heel or forefoot is frictionally adhered to a footing surface will reduce twisting stress of the shoe wearer's various foot and leg joint tendons and ligaments and being particularly beneficial in this manner for persons engaged in high stress physical sports, and also for the infirm, elderly or for those persons having foot and/or leg diseases or injuries, or the shoe soles of this invention can be worn and used by anyone who simply wants to reduce lower body stress and maintain good health thereof.
More specifically a shoe that can rotate independently at a fixed linear footing position of its outsoles is best supported most beneficially when said outsoles is made in the form of a disk coaxially connected to potentionally rotate in positional arrangement at the forefoot region of the shoe which encompasses the ball of the foot within the diameter of the said sole disk. The said sole disk preferably extending rearward from the region of the toes first joint, as at 22, to include a region of the ball of the foot, sat 23, FIG. 2. Then to attach the sole disk 16 to the sole disk attachment structure 17 the sole disk's upper inner perimeter structure is beveled inwardly forming a circular flexibly resilient lip, as at 24, having a horizontally projected undersurface 23 which together form a clasp 26 structure and by which said clasp structure the said sole disk is resiliently snap-fitted to the shoe's sole disk attachment structure 17 by first positioning the sole disk inner beveled perimeter of the clasp structure, FIG. 8 (see also FIGS. II and 12 for the position and sizes of said sole disk to shoe bottom outsole and˜top view of sole disk including well 15 and upper stepped surface 29 and clasp 26A) to engage the shoe bottom's sole disk attachment structure 17 complemental middle beveled perimeter structure FIG. 8. which together create a mechanically advantaged joining of said complemental beveled surf Ices of the clasp and catch, as at 24 and 25 when a force is applied forcing said beveled surface 24 to slide along said complementarity beveled surface 25 therefore forcing the beveled surface 24 to flex outwardly along beveled surface 25 until said sole disk clasp 26 is finally resiliently snap fined inwardly engaging into circular catch groove 27 and onto circular catch groove shelf 28, FIG. 3. And thereby clasp 26 is assembled onto said catch groove shelf 28 completing the assembling of sole disk 16 to sole disk attachment structure 17, FIG. 9 in which said assembly said groove 21 and on which said groove shelf 28 surface said sole disk attachment structure 17, held by and guided by catch 25 can rotate 360 degrees clockwise or counter clockwise on sole disk 16 holding a shoe at a linear radially fixed position to a footing surface The sole disk attachment structure's position of rotation is reinforced, guided and stabilized by its bottom level circular downward projecting beveled structural region, as at 31, FIG. 8 that coaxially fits into complementarity formed sole disk circular well region 15 reinforcing the sole disk fixed linear position at said shoe bottom. The inclined surface ISA, FIG. 8 eases assembly.
The perimeter of the sole disk is sharply tapered to a point allow a certain degree of sole disk edge resilient flexing, such as illustrated in FIG. 6 to maintain a substantial contact of the sole disk to a footing surface when said sole disk moves with a shoe to a canted position from said footing surface, which cant occurs to just about the same usual 5 degrees of cant before the foot of the shoe wearer is forced to be lifted, in response to upper body movement, entirely from a footing surface usually in response to a person making an abrupt sharp body turn and/or when turning with the feet spread substantially apart which often occurs when playing sports such as basketball and tennis. The said feature of sole disk perimeter flexing as designed to accommodate a shoe's canted configuration to maintain substantial footing surface contact as are the inward beveled sides 108 of intermediate outsoles 44 to substantially prevent canted shoe position slips and falls and especially so on court surfaces made avoidably slippery by being constantly spot wetted by drops of sweat from players.
The said sole disk perimeter flexing at a canted position also assures that the sole disk will never have an undesirable linear wheeling motion on the sole disks edge prevented by maintaining contact with a footing surface substantially inward from the edge perimeter of the sole disk at which canted configuration said edge perimeter also comes into contact with an edge region of the shoe bottom's sole disk attachment structure 17, as at 48 which acts as a soledisk brake and locking mechanism as illustrated in FIG. 6.
The following alternate embodiment of a sole disk 32 and sole disk attachment structure 33, FIGS. 3, 7 and 10 for attaching a said sole disk 32 to the bottom outsoles of a shoe provides more cushioning for the foot of the shoe wearer which is especially important for the heel region of the foot that lacks the great shock absorbing flexibility of the forefoot's many springy joint ligament connections that very efficiently absorb the shocks that occur with the aggressive physical activity of sports; unlike the heel that has only a little fleshy padding to absorb footing impact shocks.
Also in this alternate embodiment a shoe is made more unlikely to cause slippage on a footing surface especially when a shoe is lifted to the usual S degrees of a canted configuration to a footing surface, because in said canted position, in this embodiment, the entire undersurface of the disk sole 32 remains in contact to said footing surface as illustrated in FIG. 7.
Along with the above mentioned features the said alternate embodiment also has the same basic rotational means of a shoe's sole disk attachment structure 33 to rotate clockwise or counter clockwise to any point of 360 degrees connected to the circular top structure of a sole disk 33 upon which said sole disk attachment structure 33 can rotate when its attached sole disk 32 is frictionally held in place on a footing surface.
All drawing figure lines of said alternate embodiment define circular or annular structures. In the drawing of the sole disk attachment perimeter structure 33 the rounded end, as at 35A, of catch finger 4, defines the perimeter of a circular opening of said structure 33 into which said opening perimeter sole disk 32 is fitted and attached to. And said sole disk attachment structure 33 housing wall 36 and ceiling 38 all define circular structures. The additional structural features of the said alternate embodiment, as mentioned, allows the entire expanse of the bottom underside surface 34 of sole disk 32 to remain in fall contact to a footing surface by the sole disk attachment structure 33 dynamically reconfiguring its positional arrangement to a static position of sole disk 32 when shoe 19 and its bottom attached said structure 33 are canting up to the usual said S degrees of hill cant that occurs automatically, such as when a foot of the shoe wearer has canted said shoe in accompaniment to certain rapid twisting or turning movements of the upper body when that person is engaged in high stress physical sports and the said shoe's said sole disk 32 and sole disk attachment structure 33 configures in a manner as illustrated in FIG.? where the catch finger 35 of said sole disk attachment structure 33 is forced to flex upward at catch finger's rounded end 3M engaged at beveled catch groove 41 of sole disk 32, and the catch horning shell wall, as at 36, of catch finger 35. is forced to flex somewhat outward as said shell wall 36 moves downward and eventually folds against the surface of the beveled lower perimeter, as at 14, of sole disk 32, illustrated in FIG.?, as shell ceiling 38 comes down to rest against top end corner 37 of sole disk at preferred angle of S degrees as shown in FIG. 7.
The sole disk 32 is attached to shoe bottom sole disk attachment structure 33 by placing the disk at its upper most beveled surface 40 that provides a mechanical advantage when said sole disk is forced thereat to slide upwards engaged to lubricated rounded end 3M of flexibly resilient catch finger 35 which defines the resting open circular diameter of circular catch finger 35 opening which is resiliently stretched outward to open more widely as sole disk's beveled surface 40 moves upward and forces said catch finger 35 to engage forcing nibs 42 (nibs 42 may be formed as a molded integral fixed part of ceiling 38, or said nibs may be placed as the heads of screws screwed into ceiling 38, and said screws may be of a length sufficiently long enough to be used to attach the sole disk attachment structure 33 to the bottom surface of a shoe's midsole by screwing either a regular screw thread or self taping screw tread through said shell ceiling 38 into the bottom surface of said shoe's midsole) until said catch finger is forced by said nibs 42 to resiliently map-fit inwards into sole disk's beveled catch groove 41 creating—air-tight seal thereat for hollow space 50 where said sole disk 32 is then held to shoe bottom sole disk attachment structure 33 that, can by these means therefor rotate clockwise or counter clockwise to any desired radial segment position on sole disk 32 at said sole disk's beveled groove 41 engagement to rounded housing wall catch finger end 3M surface and where by wall 36 and sealed in air space 50 of the housing of said sole disk attachment structure 33 said structure can substantially flex resiliently downward and upward and substantially cant to various directional positions relative to the static position of its ached sole disk 32 by which features the unit substantially absorbs the shock energy of impacts away from the shoe wearer's foot and also substantially prevents disk sole 32 footing slippage.
The sole disk attachment structure 33 may be manufactured as an integrated special fixed region of the shots midsole layer, or optionally the outsoles layer with said structure and said midsole, or said outsoles formed as a single part by various molding techniques; or structure 33 may be formed as a separate part and mounted and attached to the underside of a shoe by any known method or practical means including attaching by screws for instance would allow the said structure 33 to be readily removed from the shoe as a complete unit with attached sole disk 32. Manufacturing of said unit can only be accomplished by any outside party only by written and signed consent of the inventor.
The said sole disk attachment structure of either embodiment may be made of any internally lubricated material, and a lubricant of stable viscosity may additionally be placed onto a beveled clasp or catch or onto the end of catch finger 35 and/or beveled surface 44 to assure ease of assembling of a unit or for creating an air tight seal for the hollow air space 50 of sole disk attachment structure 33.
The said sole disk of either embodiment can be readily removed from their corresponding sole disk attachment structures by placing the flat end of a tool such as for example a conventional screwdriver into air space between the perimeters of a soledisk and its soledisk attachment structure as for example 109, FIG. 9 and prying said soledisk from its attachment structure.
The sole disk 32 and sole disk attachment structure 33 of the alternate embodiment of FIGS. 3. 7 and 10 can be employed for uses either the heel and/or forefoot region of a shoe and will be useful when used with any style or type of shoe, and will work especially well with shoes of very large length and width sizes with which the said sole disk 32 diameter size necessary for the shoes width may extend rearward somewhat—the bendable forefoot region of the insole at the ball of the foot of a shoe wearer, and the said sole disk 32 will work properly thereat when the shoe is bent to the extreme due to the greater resilient flexibility capability of the said alternate embodiments structural means of an air space, nat 50, of the sole disk attachment structure 33 to the disk sole of a shoe to conform to extreme bending of the sole layers of said shoe.
Either embodiment of the sole disk and sole disk attachment structure can be bulk to any practical size and to any sout of foot or leg gear intended for human or aninial use such as nmy be exemplifled in FIG. I6 structure 46 having through holes 45 for screws for attachment of a proper size to the hoofs of horses or adhesives may be employed tor holes 45 in another embodiment may be provided in a thinner and smaller thickness of structure 46 for use with pop-rivets to attach the structure to a belt or any sort of leg gear, or then again, adhesives employed for adhering a unit of the invention to any kind or type of cloth, plastic or leather fabricated to fit the feet of humans or the hoofs and paws of animals.
FIGS. 13-17 show alternate embodiments of sole disks 51 and 51A and sole disk installation structures 52 and 52A that may be a preferable choice that is more practical to function with many types of dress shoes and boots and other type shoes that normally have midsoles and outsole layers fabricated from pre-existent flat sheet stock of leather and/or man-made materials, in that resect the old standard dress shoes or boots and sonic others that are new, or sold and in use or second hand can have their pre-existent manufactured shoes convened to install this embodiment of the invention by having said shoe's midsoles and/or outsoles replaced with the sole disks and sole disk installation structures of this invention made from said leather and/or man-made flat sheet stock as illustrated in FIGS. 13-17. And also shoes having the old said style or new style new standard uppers may be manufactured for sale with this said inventions units already installed with inventor's permission.
The said structures of this alternate embodiment of the invention may also be made by special order man-made materials in whole or in put as disclosed earlier in this specification.
All of the above acquirements for the fabrication and/or installation of this invention either assembled or not assembled or any part thereof can only be fabricated, acquired or installed only by written and signed contractual consent by the inventor.
The fabrication of this said embodiment of the intention can be accomplished with signed permission of the inventor by the ordinary tools of the everyday shoe repair shop for sale or installation on new or old shoes and shoes custom made for customers.
Parts for the simple construction of this said embodiment can be manufactured or fabricated in the manner that follows which as disclosed applies to both the heel and forefoot units of the invention being disclosed at times by reference numbers of the forefoot unit which may be assumed to also refer to the heel unit as they the reference numerals obviously may be applied without nun] application in a drawing figure. Said embodiment parts can be cut or die stamped from flat sheet stock materials and farther fabricated by stitching and/or the application of adhesives and also by employing screws to saw parts together and also for installation of units of the invention onto the soles of shoes including the application of heat to adhere parts together. Parts are easily matched for assembly accordingly to each parts profile an cut from flat sheet stock accordingly to the drawing figures of this specification including part profiles or silhouette shown by way of broken lines making up the whole of a region oft put
The multi-co-axial circular lines that define the structure of sole disks 51 and 5IA make up the whole of the said sole disks which a large volume manufacturer thereof may prefer to be formed by being molded into proper form by the injection molding process or other known molding methods.
The said sole disks also can be made as a two part or three part fabrication. With a two part application the bottom layer, as at 51, outsole region which contacts a footing surface may be a separate rubber pert made from a rubber material that has an excellent traction property that is bonded or sewn to the other disk part, as at 51C and 51D, FIG. 14. A three pert disk fabrication may better be suited to small volume production of the said pert such as by a shoe repair shop that could simply die-stamp all three parts of different diameters from two thicknesses of flat sheet stock. The two outer parts' as at 51C and 51, FIG. 14, having the same thickness but different diameters as illustrated in the cut-away drawing of FIG. 14. And the intermediate part as at 51D, would then have the greatest thickness and smallest diameter than the other two puts to which said parts 51C and 51 it is assembled between. To fabricate said three parts of a sole disk integrally together as a single pail. Adhering the parts together by today's excellent strong bonding adhesives may be the most practical choice by applying an adhesive to all touching surfaces and then stacking said parts coaxially together in a properly precise made jig for the purpose with the largest diameter disk part on the bottom and smallest size diameter disk stacked next and then the last pert stacked on top of the other two and then a ¾″ flat plywood disk the diameter of pant 51C finally coaxially placed on top of said parts then clamping all said parts tightly together until their adhesive has set thus making a bonded single integrated flat sole disk 5 part having a precisely grooved coaxially concentric integrated perimeters.
The two top adhered said disks of said sole disk 51 part may be made of (or all three, if another outsole bottom layer is added for the largest disk size to serve as a glued on but removable said sole disk 51 part that provides said sole disk 51 part with a bottom footing surface of increased traction) Lubricomp's Internally lubricated compounds of lower wear and lower friction such as graphite filled and silicone filled ACETYL or the LNP material, a PTFE and arimid filled Lunbricomp ACETYL that give more than five times better resistance to abrasive wear than unfilled ACETYL; also Lubricomp's polyurethane containing a proprietary filler of theirs could provide the needed self-lubricity. And as aforesaid, these chemicals modify the surface of the part to provide an “INTERNALLY LUBRICATED’ compound, but the presence of the lubricant does not affect the physical properties of the rubber part Any of the said “internally lubricated” materials, which lubricant is bound to the part material may be optional choices disclosed in the specification and others that provide maintenance-free lubricated parts without significant transference of the internally bound said lubricants to parts being lubricated; which parts lubrication features are highly desirable and will be optional choices to be employed in all embodiments of this invention as well as other like substances.
The assembled layered parts of the forefoot unit of this embodiment shown in the cut-away view of FIG. 14 along lines and in the direction of arrows 13-13 FIG. 17 are shown and named in reference to the shoe's forefoot installation of the this embodiment of FIG. 17 shown in side elevation and of which named parts also relatively correspond to liked parts of the heel unit installation of the embodiment of FIG. IS and as shown in the cut-away view of FIG. 16 along the lines and in the direction of arrows 16-16 of FIG. IS. all of which are fully disclosed within the following specification.
The shoe's midsole, as at 52B of the cut-away view of FIG. 14 and bottom shoe sole view of FIG. 13 forms the first layer of said sole disk attachment structure 52 and as relative to FIG. 16, cat S2C. The second layer is formed by shim 52D which fits between the midsole 52B and outsole 53 FIGS. 13 and 14, and fills all of the space there between contiguous to broken line top perimeter of sole disk 51. Likewise the shim 52E of FIGS. 15 and 16 serves the same purpose as said shim 52D illustrated in FIGS. 13 and 14 (which is to support separated positions of outsole 52A and midsole 52C and allows soledisk 51A to rotate freely at groove as at 51D FIG. 14). Said shim 52E, FIGS. 15 and 16 is cut to the same silhouette as outsole 53A and—inner annular cut of said shim 52E is cut to contiguously follow the broken line outer perimeter structure of sole disk 51A. Said shims 52D and 52E supports and stabilizes outsoles 53 and 53A positions as mentioned, as at and on the stepped 51C and grooved 51D periphery of said soledisks 51 and 51A at which said step 51C and in said groove 51D said outsoles,as at 53 FIG. 13,and as at 53A FIG. 16 hold said disks 51 and 51A in position at midsoles 53 and 53A attachment to upper shoe (shoe not shown) which therefor guide and hold the upper shoes to rotate on and around said sole disks by shoe wearer clockwise or counter clockwise as indicated by arrows. Said outsoles 53 and 53A can be attached and held in place to said midsole by self-tapping screws, as at 54 and/or by applying adhesives which also hold said shims in place. Said attachment means can be employed to attach outsole 53 to Midsole 528 of FIG. 13 except said adhesive would not be applied no farther rearward then the second rearward half circle region of sole disk SI FIGS. 13 and 17, with the remaining rearward removable flaps 538 portions of said outsole 53 held in place by only six self-tapping screws, which said screws can be removed and lime two said outsole flaps 538 lifted away from said sole disk in order that said sole disk can be removed and repaired or replaced with a new sole disk, which new sole disk may have any kind of tread design including changes in design of the sole disk itself to meet any kind of change of use or application of said shoes being re-soled with the new sole disks. This embodiment of the invention has all of the same basic functions as functions of all prior embodiments of the invention (except that it has no significant shock absorbing function) including a resiliently flexible disk sole perimeter which can flex to approximately 5 degrees to accommodate a canted position of shoes of the shoe wearer which said shoe's disk soles flexed perimeters maintains greater edge region tractional contact on a footing surface to more efficiently prevent slips and falls by the shoe wearer than can conventionally soled shoes of this type.
In the shoe heel region embodiment of attached sole disk 51A and sole disk attachment structure 52k FIG. 15 and 17, the sole disk 51A also has a resiliently flexible perimeter as at 51G, FIG. 15, that has the same function as disclosed for sole disk 51 flexible perimeter 51B, FIG. 17. Also in this embodiment the shim 52E and outsole 53A are held in position preferably only by self-tapping screws, as at 54 which also hold sole disk 51A in position and which said sole disk can also be removed and replaced by removing and then reinstalling said self-tapping screws that first allow said shim and outsole 52E and midsole 53A to be lifted away from said sole disks for sole disk removal and replacement and self-tapping screws reinstalled to tie the unit back together again. The heel region embodiment of the invention also has all of the same basic functions sail—embodiments of the invention including sole disk sole perimeter resilient flexing but not a significant shock absorbing faction.
A shoe having a unit of the said invention installed on its sole heel region and forefoot region cannot rotate on sole disks at both said regions at the same time but can only rotate on a single sole disk located either at the said heel region or forefoot region and only when the shoe wearer lifts either the shoe's forefoot region sole disk off of a footing surface to rotate on said heel region sole disk; or lifts the shoe's heel region sole disk off of a footing surface leaving only said shoe's forefoot region sole disk to rotate on. And when said heel sole disk and said forefoot sole disk are both on a footing surface at the same time of the same shoe neither sole disk will be able to rotate and said shoe will have full non-slip fictional in place traction.
As aforementioned, assembling of the unit parts of this embodiment onto a midsole of a shoe is to simply match the profile silhouette of each part as by first preferably placing sole disk 51 FIGS. 13 and 14 on a shoe's midsole 52B (having first removed the old standard outsole from old shoes or prior manufactured new shoes; or optionally installing directly onto an outsole therefore double soling a shoe with said unit) and then adjusting placement of said sole disk with placement of the forward toe piece of shim, as at 521). And after clamping said shim 52D and sole disk 51 properly in place on midsole 52B then placing the shim's two separated end flaps, as at 52F, in place snugged up against the sole disk and toe shim and clamping all said parts in place and in like manner install the outsole's four pieces, as at 53 and 53G, and finally installing all outsole self-tapping screws, as at 53A. and then inspecting units perimeter to see if any excess material needs to be trimmed off to complete units installation on shoe's indsole. It is noted that some of the shim and outsole part's materials may be flexible enough to work into outsole's groove 51D FIG. 14 cut as single pieces of shim and outsole materials instead of two or three cut pieces thereof.
The rearward portion, as at 51E, of sole disk 51 is left free of shim 52D and outsole 52 parts to allow very large diameter sole disks necessary for very large shoe soles to remain flat in traction against a footing surface when the shoe wearer lifts a shoe's heel region off of said footing surface and therefore must bend the forefoot region of the shoe at the ball of the foot of the shoe wearer as exemplified in other embodiment illustrated in FIG. 2 where the shoe size requires the extra-large forefoot region sole disk sole, where however the other said shoe embodiment is small enough to fit the shoe's forefoot sole disk 16 at or forward of the apex of the bent outsole 4-4 at the ball of the foot of the shoe wearer and therefore the said sole disk 16 remains flat on a footing surface as illustrated.
In the embodiment of FIGS. I and 2 the sole disk 16 as illustrated in FIG. 2 can be modified to also free up a small rearward portion of the sole to fit and work well on shoes of very large length and width sizes simply as shown in the exploded view of sole disk's sole disk installation structure of FIG. 4, and assembled view of FIG. 5 by creating a rear inclined area of catch groove shelf, as at 258 which opens said sole disk groove 27, at inclined groove shelf 288 and also inclining the widened region of sole disk groove wall 27, as at 28C inward, thereby freeing-up sole disk installation structure at rearward region to freely bend up and away from a rear end region of the sole disk 16.
The horseshoe embodiment below of this invention shown in FIGS. 19-22 is designed to decrease or stop twisting forces that presently do occur to a horse's legs and often cause serious injury when shod with conventional horseshoes that have protruding horseshoe nail heads and various horseshoe tread ridges designed for traction that can easily snag on various pathway surface materials, especially hard and semi-bard man-made materials the horse may be on.
FIG. 19 shows the full curved profile of a horseshoe of this invention which perimeter does not define the arc of a perfectly circular structure. But all seventeen rollers 73 are in positional arrangements in the bottom curved structure of said horseshoe with all of their horizontal axes of potential rotation pointing to a common central point of a hoof determined to be the vertical axis of potential rotation of a horses hoof about which the rolling surfaces of all rollers will, when required, roll about following their individual circular orbits of rotation around said vertical axis of said hoof which therefor avoids snagging an small obstacles on the pathway of a horse; which said roller features are exemplified in more detail as follows:
When a horse, shod with horseshoes of this invention, is stepping along a pathway and brings a hoof down onto said pathway where, by chance, small obstacles on the pathway are then touching various sides of the projecting flat ends 95 of a horseshoe's rollers 73 and the horse then begins changing direction with a rotational movement of one or more of its hoofs kept linearly in place on said pathway. Question: Will the horse's said in place turning horseshoe of one or more hoofs become snagged at said pathway obstacles which are touching the straight sides of the said horseshoe's rollers 73 when die horse attempts to rotate its said horseshoed hoof or hoofs either clockwise or counter clockwise around the vertical axis of a hoof The answer is no the said hoof will not get its horseshoe snagged on said pathway small obstacles because even when two such obstacles are touching both flat ends of any or all said roller 73 such as, for example, the fifth roller at the right side of the bonds horseshoe moving clockwise of which the said obstacles touching the sides of said fifth roller 73 must therefore lay at die outside of the circular orbital movement of said roller which said roller will take and therefor will neither move against nor most away fran said pathway obstacles touching the said straight sides of roller but merely brush against said roller without increasing contact pressure as said roller follows its said orbital movement of the horseshoed hoofs rotational movement about its vertical axis at said pathway unimpeded by said obstacles. All but two rollers 73 at the ends of the horseshoe following the fifth roller mentioned will roll over said obstacle rolling within and outer region of the said fifth roller's orbit with the fifth next to Inst said following roller 73 at the opposite left side fork of the horseshoe also only brushing against said pathway obstacle and not increase pressure against it, and the following remaining four rollers of said opposite fork of said horseshoe will each follow orbits that are at the inside region of first said fifth roller's orbit and therefor will also roll over the obstacle that was at the opposite inner flat side of said first fifth roller but will not roll over obstacle at opposite end of said roller. In other words all seventeen rollers of the said horseshoe will either roll along the touched side of, roll over or entirely miss any random positional arrangements of pathway small obstacles without any said pathway small obstacle becoming snagged at said horseshoe rollers. Other featured factions of said rollers and accommodating structures of the horseshoe to deal with and avoid adversarial hone pathway objects are disclosed below.
It is well known that serious injuries often occur to the legs of homes, and mostly to their complex lower legs regions including inflamation and/or tearing and separation of their Sesamoidean ligaments, Suspensory ligament of the navicular bone, T-ligament, Common extensor tendon, Annular ligament Deep flexor tendon, Impar ligament Coffin joint. Pastern joint and Fetlock joint which injuries are often brought on by over-extension resistance to abnormal physical twisting forces originating at the hones hoofs not moving as they should in coordination with the horse's upper body movements as the horse places its weight on a conventionally shod hoof which had become perhaps only momentarily somewhat snagged on a pathway surface obstacle while attempting to turn its body but nevertheless often eventually causes end disease serious injury and great immobilizing pain to a horse. Concrete with a rough surface to prevent slippage is often found as the floor material of choice for horse stables and which is a primary example on which surface horseshoes of a hone may time and time again become momentarily snagged at and generally somewhat resist twisting sliding movements of a horses hoofs, which action most of the tine goes unnoticed by a horses handler, unless the home is seen to have been actually tripped by said obstacle˜ and gradually causes serious inflamation first, and over time, as concerns the horse's suspensory ligament, may degenerate to incurable end disease states such as the one known by vets, as Degenerative Suspensory Ligament Desmitis (DSLD), and then if the hoof finally becomes sagged hard enough, and again for perhaps only for a split second, may cause a ligament or even a tendon to eventually become permanently stretched or even partially or filly torn loose from a bone joint or muscle and the degenerative cause of the injury remaining a mystery. The common paving material called asphalt may also be a risky surface for a horse to walk on, especially black asphalt which absorbs heat from the sun easily and somewhat softens, and anything projecting from a horseshoe can get easily get caught up hard into its surface. And other surfaces are also risky, such as the expansion grooves of sidewalks and wooden boardwalks. In other words most man-made surfaces, hard or even somewhat soft, are not kind to a hone's legs. Such surfaces repeatedly cause stress to horses so insidiously that homes come to said incurable disease Mates with handlers never noticing before hand that these hones are being stressed in ways just disclosed. It should, therefor, be realized by horse owners that a horse might be constantly in pain from sore hoofs and legs caused by such pathway materials but not injured enough to have a noticeable limp or other signs of injury. Think of people feet which some hurt badly but people often don't show it in the way they walk. And it should be realized, too, that the lower legs of horses that are designed by nature town hard on all kinds of natural surfaces are not particularly very sensitive to pain and therefor when a horses legs are stressed the horse most of the time does not react emotionally to the stress, not even to chronic leg diseases before the end stage of the disease.
The said horseshoe embodiments of this specification are designed to have a long serviceable life with features to decrease or prevent said twisting forces from occurring to a horses legs in such a manner as to be most comfortable and safe in their application with minimum transference of heat, vibration and shock from said horseshoes to the hoof of a hone while allowing free flexing of not only the frog region of the hoof but free flexing of the entire wall of the hoof while providing overall reduced stress to a horse from outside fortes. Said horseshoe has eleven parts for its installation to a hoof Said horseshoe parts as shown in FIG. 22 are as follows:
Main one piece horseshoe body 86 which has the silhouette profile of the horseshoe. Resiliently flexible spring 75. Roller box 74. Roller 73. Resiliently flexible bottom layer 77 and integral roller keeper seal flaps 77A (an additional foam layer may be added to provide insulation). Thin flat steel or high impact plastic bottom cover plate 94, which has open regions for roller keeper seal flaps 77A and cover plate screws 14. Said cover plate 94 protects and holds flexible bottom layer 77 and integral roller keeper seal flaps 77A in place against the main body S6 of the horseshoe. Small self tapping screws 14 screw through bottom plate 94 and through flexible layer 77 and into horseshoe main body 86 to scan said bottom cover plate 94 and said flexible layer 77 to bottom of horseshoe. Large interior self-tapping horseshoe screws 91 secure the main body S6 of the horseshoe to the hoof of a horse in a special unique way to allow the frog region and entire wall of the hoof to flex normally slightly outward and resiliently back inward (most horse handlers and owners still think that only the frog region of the said hoof has flexural movement) which said normal hoof flexing action acts as a shock absorber which helps to reduce concussion on the hoof and legs of a horse when contacting a pathway surface.
It is important to know why it is so important to allow flexing of the entire hoof wall explained as follows: As mentioned, the horse hooves are extremely complex structures, very sensitive to stress and pressure and with an excellent blood and nerve supply. On the outside and underneath, they are protected by a horn, generally known as the wall of the hoof (a form of modified, hardened skin) which grows down from the coronet band, a fleshy ridge around the top of the hoof equivalent to the cuticle on a human nail. Inside the hoof the horny (wall) outer structures are tightly bonded to the sensitive ones by means of leaves of horn and flesh (called laminae) which interlock around the wall of the hoof The sensitive structures themselves surround the bones of the foot. When weight is put on the foot (hoof) it flattens and expands slightly, (flexes outward) squashing the sensitive tissues and blood vessels between the horn (wall) outside and the bones inside. The blood is squeezed up the leg into the veins, which have valves stopping the blood naming back again. When the weight is removed (from the hoof), fresh blood rushes back into the tiny vessels (called capillaries) and so the process goes on.
It was thought until very recently that it was almost entirely pressure on the hoofs frog region which pumped the blood around like this, but recent research has shown that, although the frog plays a part; it is the expansion of the whole foot (allowed by flexible expansion of the hoof wall ) which is important The frog region, together with the plants cushion inside the heels of the hoofs foot, mainly helps reduce concussion on the foot.
Today millions of horses feet are tied to horseshoes which do not allow proper blood flow to their legs which may be another contributing factor of leg tissue breakdown which can lead to the widespread disease known as DSLD above,
When shoeing a horse with a horseshoe unit of this invention which allows fill free outward flexing of the entire wall of the hoof the said horseshoe unit may be precisely positioned on the hoof of a horse by known & as a professional farrier knows, the anatomy of the bottom parts or regions of said hoof. The forefeet hoofs have a different anatomy configuration orientation than that of the horse's hindfeet hoofs. The said forefeet hoofs are much more round in shape than the hindfeet hoofs, the hindfeet hoofs being much more pointed in shape than are the forefeet hoofs. Therefor said horseshoes will be made in shapes for fitting to either the said forefeet hoofs or said hindfeet hoofs as well as coming in different sizes in accordance to the size and type of horse to be shod. All sizes and shapes of said horseshoes have rollers, which as disclosed, will self-adjust automatically to the vertical axis of rotation of all types, sizes and shapes of a horse's hoofs. And all said horseshoes will have a horseshoe main body 86 horseshoe screw holes formed large enough to accept various degrees of outward movements of screw shanks 96 within screw hole air space 97 to allow a safe and proper full magnitude of flexing of a hoof wall for all types of horse hoofs below. Prior to Adding any type of horseshoe to a horses hoof the said hoof must first be properly filly prepared for accepting a horseshoe in accordance to the particular condition of each individual hoof In addition horseshoes of this invention require that the bottom surface of a hoof and especially as concerns the hoof wall should be made as homogeneously flatly level and smooth as possible in order for the said horseshoe, which will allow said hone's hoof wall to flex on its surface, to have a complete closely fitted contact with said hoof. Also a stable viscosity water seal grease, nil grease or any such product compatible to the health of the hoof should be applied between the bottom surface of said hoof wall and top surface of said horseshoe to assure freedom of flexibility of the hoof wall on said horseshoe.
The horseshoe is attached to the said hoof by the special and unique interactive structures of the horseshoe screws 91 and horseshoe main body 86 horseshoe screw hole 89 structures which together accomplish complete flexural freedom of a hoofs flexible wall. The large diameter self-tapping threaded 99 region of screws 91 have smooth round shanks 96 of much nailer diameter than said screw threat 99, and which said shank 96 diameter is directly attached to the screw head 90. The horseshoe main body 86 screw hole 89 is minutely smaller than said screw thread diameter region 99 which permits a snug or partially screwed in fit of said screw's thread region 99 to said main body screw hole 89 wall. Said large self-tapping horseshoe screws 91 attaches the horseshoe main body 86 with roller boxes 74 and rollers 73 already assembled in it to a horses hoof wall in the following manner: First, with the horseshoe main body 86 downside turned up, self-lubricating washers are placed onto screw hole's bottom end right angled screw head housing overhead surface 102, as at 100 and lot, Fi& 22, which act as self-lubricating screw head flat washer bearings which may be made of internal-lubricated materials such as Acetron NS or Parker Compound N1090-85 or PTFE Compounds or Hytrel Type HTX-8177 which may also be primary or optional choices of materials for other parts of the horseshoe, The first larger washer 101 has a round axial hole of a diameter slightly larger than the diameter of screw hole 89 wall diameter, and said washer 101 has—outer perimeter diameter which completely coven right angled screw head housing overhead surface 102 to diameter of said housing's vertical wall 104. Next a self-tapping horseshoe screw 91 is screwed or force fitted into screw hole 89 which precisely guides said screw 91 to a position therein as illustrated at the left side of drawing Pig. 22 with a small portion of screw point projecting from top of horseshoe main homing 86 surface screw hole 89. To properly gauge the depth of all said screw shanks 96 into said screw holes 89 and magnitude of projection of said screws 91 pointed ends projecting from said horseshoe main body 86 a simple screw gauge of proper length can be made from round molding of a diameter larger than that of screw head round housing wall 304 diameter and cut to proper length and grooved along its long axis to accept screw shanks and placed sequentially onto all said screw shanks 96 with one end of said gauge placed against underside of screw head 90 which precisely limits the length of all said screw shanks 96 to the same depth length screwed into said screw holes 89 and therefor also the—magnitude of projection of each screw 9 point projecting from said horseshoe main body 86 screw holes 39 as illustrated at said left side of drawing Pig. 22 All remaining horseshoe screws 91 and washer 101 are assembled in the same manner and configuration into said horseshoe main body 86 screw holes 39. The second said nailer washer, as at 100, has a two part split axial hole diameter that is assembled to all horseshoe screws 91w snugly fit onto screw shank 96 diameter, and said washer 100 has—cuter diameter of the same size as the screw head diameter. Next a proper length of preferably coiled fatigable resiliently flexible oblong hollow plastic keeper tubing 103 is forcefully slightly compressibly fitted completely around and between screw head 90 screw head washer bearing 100, and screw head housing vertical wall 104, and against washer bearing 101. Tubing 103 as shown placed therein keeps screw shank 96 reboundably centered within screw hole 89 air space 97; below. The said horseshoe main body 86 top is greased and is now ready to be carefully positioned by a farrier onto the uplifted prepared hoof of a horse and all said assembled horseshoe screw heads 90 with points projecting from the horseshoe main body 86 to the same length are all lightly tapped at the same time by employing a small piece of ¾ inch plywood onto all said screw beads 90 and centrally striking said plywood moderately with a hand sledge until all said screws 91 projecting points have been driven into the wall of said hoof and then said plywood removed and said horseshoe main body 86 is then pulled off of hoof and all the horseshoe screw indent marts left in said hoof wall by said horseshoe screws are inspected to be sure that they we all correctly positioned for safe complete driving of screws all the way into the wall of the hoof and having passed inspection for correct positions the horseshoe main body 86 is then repositioned back into hoofs said the prior screw indents made and all said horseshoe screws 91 driven all the way into the hoof wall ending with all of the screw's threaded region 99 screwed into the hoof wall leaving only the screw shank 96 centered in screw hole air space 97 with the said screw heads lightly pressured against the horseshoe main body 86 and finally all screw heads 90 are torqued to two foot pounds of torque each, by employing preferably a battery operated power screw driver equipped with an adjustable torque gauge with an automatic click release. All said screw heads 90 having been filly seated on their washers are backed off slightly with one eight turns until the farrier can feel some slight sideways movement of said horseshoe main body 86 on the hoof by said farrier pushing hard on the side of said horseshoe main body 86 and having accomplished that last step the said horseshoe main body is now fully mounted to the underside of the hoof. Then the flexible layer 77 is properly mapped onto the heads of all bottom plate screw 14 heads. Next the bottom plate 94 is mounted in place by slipping bottom plate 94 keyholes onto all extended bottom plate screw 14 heads and pushing said plate to one side to lock it in place and tightening down all said screws 14 and the horseshoe's fill assembly is now mounted to the hands hoof Mounting of the horseshoe main body 86 in this manner allows fill free flexing of the hoof wall because the full length of the horseshoe screw's large diameter threaded ends 99 have all been screwed into the hoof wall leaving only the much smaller diameter screw shank 96 left in horseshoe main body 86 screw holes 89 with a large air space 97 left fully around said position of screw shanks 96 and therefore when a horse steps down on a pathway the wall of said hoof flexes outward with said treaded region of horseshoe screws 9! fixed in place in said hoof wall and therefor moves the smaller diameter attached screw shaft 96 with it to one side of screw hole 89 air space 97 and therefore too, also slides the screw head 90 with self-lubricating washer ICC to one side of screw head housing 104 compressing keeper tubing 103 to the right and left sides of screw head housing walls 104 at the right and left arced sides of horseshoe and therefor the weight of the horse on its hoofs outward flexed walls keeps the horseshoe unit always in a proper stable positional arrangement on any said hoof the horse may be standing on or walking and running on because each screw attached to the flexed wall of a hoof, while said hoof remains standing on a surface, has moved outward at a different radial segment angle plane at each installed site at said right and left arcs of the horseshoe and also of the right and left arcs of the hoof wall However if said raised horseshoed hoof did not have automatic self centering means to the hoof of the horse and the horse brushes a shod hoof against anything on the way up the hoof's horseshoe could be slightly moved on the hoof and therefor no longer centered on it for the next step downward, but this cannot happen because all resiliently flexible keeper tubing 103 wrapped at each bead 90 of the horseshoe screw would be compressed by movement of said screw head 90 to any direction off center of screw hole 89 and therefor all said resiliently compressed tubing 103 would thereafter rebound against said screw heads 90 which ganged action always moves said screw shanks 96 back to center of said screw holes 89. The horseshoe main body 86 screw holes 89 will be of one sufficient diameter size universally large enough to allow safe free full flexing of any size or kind of hoof to any degree or magnitude of hoof wall flexing made possible by employment of said resiliently flexible screw head keeper tubing 103 aforesaid centering means disclosed for centering screw shanks 96 within screw holes 89 air spaces of one common maximum size screw hole 89 for many different sizes of horseshoes.
The main body 86 of the horseshoe is preferable made of Ultrahigh-Molecular-Weight Polyethylene which resists abrasion, is tear resistant and has vibration dampening and heat absorption resistant properties and is easily molded and/or machined. The rollers, as at 73 may have flat rolling surfaces, as in FIG. 19, or preferably have slightly concave rolling surfaces, as exemplified in drawing FIG. 21, as at 79, (shown exaggerated forsake of illustration) that provide minimal surface contact to a hot surface of horse pathways while allowing cooling air flow to flow between said hot surface and the arched concave surface of said rollers; and said roller concave surface also provides sharp corners of minute radii for minimal roller bearing surface contact with the bearing surfaces of roller box 74 in the main body of the horseshoe, therefore, broad areas of bearing surface wear of rollers 73 is avoided and heat transference of said rollers to a horse's hoofs is held to a minimum while said rollers 73 small bearing surfaces spread out wear against the much more broad bearing surfaces of the arced corners and overhead of roller boxes 74; which rollers 73 actions gives the internal-self-lubricating property of roller boxes 74 bearing surfaces long lives.
The horseshoe writ is attached to a hoof with self-tapping horseshoe screws and threaded holes thereby formed in the hoof wail of a horse can be used over again a number of times when exchanging the basic identical horseshoe main body 86 FIG. 22 of a horseshoe of the invention that will be made in a choice of sizes to fit a variety of horse hoof types. A given length of a horseshoe screw with self-tapping screw threads has much more holding power than that of the same length of a tapered smooth sided horseshoe nail that must take a different—of entry and be highly force fitted into a hoof each time a new horseshoe is Installed leaving close by healed and open scars in the wall of the hoof where earlier nails have been driven ‘in with a hand sledge and removed and leave more stress damage to a hoof and cannot be placed and then driven into the a hoof wall—accurately as self-tapping horseshoe screws can be into the relatively small width of space occupied by the hoof wall by being precisely power screwed with said screw pulling itself into a hoof wall while shaving away a precisely consoled unstressed pathway threaded hole into said wall with precision guidance provided by the horseshoe's main body 86 horseshoe screw guide holes 89 to which said horseshoe screws fit snugly into and are guided to a predetermined precise sat angles of direction into the wall of a hoof causing no entry stress and without chance of straying into any sensitive region of the hoof as sometimes occurs when a farrier sledges in horseshoe nails which have a long tapered structure of which a conventional horseshoe nail hole cannot accurately guide as said farrier hand sledges these said horseshoe nails guided only with the farriers two fingers only part of the way into a hoof with high force sledging tops˜aside and permanently highly compress parts of the hoof at the nail's entryway and exit hole where the protruding nail end must then be sledged sideways onto the hoof for added holding power and excess twisted off which is the old crude way it has been done for hundreds of years and persist until the present day and horses still suffer today by this predominate crude way of shodding horses with the usual iron horseshoes which work should be done as safely as it can be done only by the expert work of highly professional fairies which today are very hard to find and a dying breed. Today most horses are shod by part time neophytes who call themselves “farriers
The horseshoe's rollers 73 all have a horizontal axis of rolling rotation which lay at a different radial axial plane from any other said roller because the horseshoe structure does not define a perfect circle nor neither does the hoof wall of a horse, therefor each roller's horizontal axis of rotation must be placed differently into the horseshoe to have the potential to roll around the vertical single axis of a hoof with all said rollers said horizontal axis in their radial segments pointing to said single vertical axis of potential rotation of a horse's hoof necessary to allow each said roller to potentially roll along its own individual coaxial annular path of least resistance around said hoofs vertical axis.
Each roller 73 has two flat constant tight angled vertical plane sides as shown in FIG. 23. Therefor each said roller has flat end surfaces at right angles to the roller's horizontal axis of rotation. And because each said roller follows a circular pathway each with a different radial line segment axis of rotation that joins to the single vertical axis of said hoof, each said roller's sharply cornered vertical plane sides therefor are each presented radially to a pathway at different radial segments of lateral angles of attack to the surface of said pathway, either hard or soft, to resist linear force of movement of a horse's hoofs in 17 different directions presented by said 17 rollers of each hoof's horseshoe on said path when a horse is either standing on an incline or in stepped tractional movement on an icy pathway with said horseshoe's concave rollers providing reliable traction, and at the same time said potential rolling movements of said rollers 73 of the horse's horseshoes allow easy turning movements when required of a hoof to rotate about its said vertical axis while still providing excellent resistance to linear slippage in any direction of said hoof with the said horseshoe rollers magnitude of projection from a horseshoe empirically adjustable to provide only a practical safe force of general resistance of horseshoe pathway slippage generally applied to all surfaces m a manner not stressful to a horse accordingly to its particular footing environment and also relative to the horses size, weight and type of predominant physical activity to allow some safe healthy slippage to occur to avoid stressful abrupt stoppage of movements of the horse's legs. The amount of projection of said rollers 73 from the horseshoe main body 86 is determined by the vertical length and wire thickness of the coil of springs 75 of which a variety of spring 75 sizes will allow custom adjustments of the magnitude of projection of said rollers 73 to a limit of projection, as illustrated in FIG. 22. said spdngs 75 can push a roller box outwards from a roller box compartment which said compartment be formed somewhat vertically higher than shown to allow a greater variety of said projection and still have room for substantial compression of spring 75 to properly work the shock and ventilator features afore disclosed of the horseshoe.
In other words, because each roller's axis of rotation is aligned to the single axis of potential rotation of each of the hone's hoofs the horseshoe rollers can roll with and follow the annular rotational turning movement of the horse's hoof about said hoofs single vertical axis while resisting linear directions of rolling or slippage movement of a hoof along the surface of a pathway, while with said rotational movement of a horses hoofs said horseshoe rollers will ride up and roll over small obstacles on a pathway that an ordinary conventional horseshoe may snag upon.
No two Horses are exactly alike—and not even the hoofs of the same horse have their vertical axis all respectively located at the same exact point of rotation of a hoof The point of the vertical axis of a hoof is substantially located generally for all horse hoofs at the forward point of cartilage space where inside a hoof the Navicular bone (distal sesamoid) meets the Coffin bone (Distal Phalanx). And this said axial point of actual rotation is different for each and every hoof accordingly to the fine physical structuring of a particular horse—d a particular hoof. Although the said differences of hoof axis is not great it is important for the general well being of a horse shod with horseshoes of this invention for rollers of said horseshoe to be able to find and point to the location of each hoof axis of rotation to enable a horse to rotate its hoofs as easily as possible as wild horses can with their bare hoofs romping on the plains and desert surfaces of natural mother earth.
Therefor a particular feature of said horseshoes is that all rollers 73 of FIGS. 21 and 22 are designed to automatically adjust their horizontal axis of rotation to find and point to the single vertical axis of rotation of a horses hoof by said rollers fluctuating their horizontal axis of rotation about their vertical axis to find and follow a—of least resistance coaxially around each hoofs said vertical axis below.
To assure long life of this horseshoe said rollers also automatically adjust themselves for wear of their bearing surfaces to maintain tight roller seals against invasion of significant amounts of dirt and grit particles into interior spaces of the horseshoe.
All bearing surface parts of the horseshoe, including roller keeper seal flaps 79 are self-lubricating from the internal-lubricant of the material of which parts with bearing surfaces are made of and therefore are maintenance free with said lubricant remaining within the physical bounds of the bearing surface of the material of a part which said internal-lubricant is a bound component of.
Rollers 73, FIGS. 2I and 22 may be made from tungsten metal, of the lesser fragile type, to retain uniformly smooth contact bearing surfaces for a long period of time which uniformly meet seal surfaces without open spaces to maintain sealing of parts again internal invasion of significant particles of dirt and grit as mentioned. But, too, in this regard the horseshoe is designed to have rollers and other bearing surface parts that when worn out can be quickly and easily removed and replaced while the basic foundation of the main body 86 of the horseshoe, that is designed to last much longer than its bearing surfaced parts, remains in place on the hoof of the horse and therefor exceptionally long wearing rollers of tungsten are not necessarily a critical part nor necessarily the only choice for roller material and therefor Metal Compound or Acetron NS rollers which are much less costly to produce, are lightweight vibrate less and quieter in operation than tungsten, wear well and strong enough to replace steel may be preferable choices.
FIG. 20 shows a side elevation schematic view of the horseshoe main body 86 in particular reference thereof of this invention to a pointed toe 84 region of the horseshoe integrally formed wit a toe riser 82 which said riser projects upwards higher than the remainder of the horseshoe's horizontal structural height and designed to butt against a complemental vertically flied right angled surface region 83 of the toe of the hoof which resists all backward shilling of said horseshoe. The said riser 82 and its inclined front surface toe region which slopes downward to form an artificial pointed hoof toe region 84 are integrally secured regions of the front end of the one piece horseshoe main body 36. Said pointed toe front end 84 is designed to be an extension of the naturally inclined sharply pointed form of the toe of the hoof which mother nature in her infinite wisdom designed for the fast running horse to keep the quick forward movement action of a hoof from being too often too abruptly stopped on a soft surface the hoofs may dig into when a horse is romping or galloping about on soft earth to prevent stress injuries to the complex structure of the horses lower legs and hoofs by providing a sharply inclined pointed hoof thus having the mechanical advantage to dig in and push aside some of the said earth therefor more safely gradually dissipating and absorbing impact forces to the hoofs and legs of the horse to bring the horse to a gradually baited position. If said hoofs were structured with blunt front surfaces the horse when attempting to dig in at a surface with its hoofs when slowing down for a turn or coming to a complete stop from a running gate would under such circumstance either most likely slide rapidly in any direction or most likely forced to very abruptly dig in and causing the horse to come to a complete sudden stop so abruptly that the horse's legs may fold under it by the over-riding force of the stored kinetic energy in the long horizontal main body of the horse; and if not made therefor to fall could strain and cause injury to its lower legs especially if such an action is done repeatedly.
In FIGS. 21 and 22 structural elements and functions are disclosed of the horseshoe in more detail. As previously mentioned roller 73 can adjust its wiling direction to follow the orbit of rotation of a hoof around its vertical axis to the extent of a back and forth twisting movement of said roller revolving intermittently somewhat about its vertical axis allowed within the confines of roller box 74 of which interior four straight walls of said box 74 have a widths greater than the length and diameter of said roller 73, but the surface of the arc of the interior wall rounded four corners 74A of said box 74 are contiguously nearly within the same partial orbital path taken by the corners of said roller 74 in twisting movements about its vertical axis within said confines of said roller box 74 as shown illustrated in FIG. 21 with the interior boundary of said box 74, shown superimposed with broken lines 74 where it can be seen that only the minute radii corner edge surfaces of rollers 73 touch the arced corner surfaces of roller boxes 74 and also only the same ends of the slightly concave roiling surface 79 of said rollers come into contact with the overhead surface SO of said roller boxes 73, which said bearing surfaces configuration allows a quickly started and efficient movement of said rollers having little frictional resistance to overcome with benefit too of each ro's horizontal axis of rotation automatically being exactly radially aligned to tract around with a hoofs rotational movement around its vertical axis while each said roller has a little give in their coordinated abilities to absorb shock by being able to be fated more deeply into the body of said horseshoe and to twist somewhat about their vertical axes when striking nail obstacles to ride up and roll over on the pathways of a horse; while with these said actions including said twisting movements of said rollers which spread out bearing surface wear on roller boxes 74, said corner bearing surfaces 74A which therefor increases the life of the more broad bearing surface areas of said roller boxes contacted by the sharply rounded small minute radii bearing surfaces of said rollers thus constantly shifting points of contact to the much more broad co-bearing surfaces of said corners and overhead of said roller boxes 74.
In addition to the above said movement of rollers 73 within roller boxes 74 said rollers also move Anther into the horseshoe main body 86 to absorb the shock of applied force of some of the weight and/or strength of a horse impacting said horseshoe rollers with each down-step against a pathway's surface causing said rollers therefor in turn to force roller box 74 overhead to press against resiliently compressible spring 75 telescopically compressing the coil of said spring that is in a positional arrangement between the exterior surface of roller box overhead roofed roller box compartment 76 overhead surface which said movements of parts and compression of said spring thereby absorbs some of the shock of said rollers—said pathway surface.
Also, when said force of weight and/or strength of said horse is relieved from a horseshoe roller box spring 75 the said spring expands and pushes said roller box outwards to rest against resiliently flexible seal layer 77 which seals off vent grooves 12 and 13 (below) and also pushes roller outward more tightly against roller keeper seal flaps 77A and which expansive force of said spring seal off vent grooves 12 and 13, and keep flexibly resilient roller flaps 77A against rollers 73 which provides quiet operation of a horseshoe by dampening sound vibration and keeping said movable parts from rattling around within said horseshoe with stepping motions of a horse.
These said workings of the horseshoe also work to provide a ventilator system feature of the horseshoe when as aforementioned said roller box 74 moves more deeply into roller box compartment 37, therefor stale air and/or fluid rapped inside of horseshoe between said roller box 74 roof and interior walls of roller box compartment 87 are fated to flow out of horseshoe along roller box exterior wall vent groove 13 engaged to now opened roller box compartment interior wall vent groove 12 along which said air flow continues its journey out of horseshoe between roller 73 and roller seal flaps 77A and also out between Y-slits at corners of said roller boxes 74. And when the horse raises its shod hoof off of a surface and pressure is relieved off of a horseshoe and therefor off of horseshoe rollers 73, the said roller 73 and roller box 74 then mow outward from roller box compartment 87 and therefor die said roller box sucks some air back through vent grooves 12 and 13 and into air space being created between said roller box 74 and roller box compartment 37 as said roller box 74 continues to move outward until the bottom perimeter of said roller box 74 engages and is pressed against seal layer 77 by expansive force of spring 75 which action then blocks the outer opening of engaged vent grooves 12 and 13. And when the boasts shod hoof is again pressured against a surface said roller 73 again forces said roller box to move again more deeply into roller box compartment 87 and away from seal layer 77 which action unblocks outer opening of vent grooves 12 and 13 . . . and so it goes, keeping the horseshoes ventilated and cooled with each stepping action of the horses legs.
Each roller 73 is provided with a die-stamped resiliently flexible and preferably internally lubricated said roller keeper seal flaps 77A that are integrally connected to seal layer 77 FIGS. 21 and 22 that has roller openings with corner V-slits at all four corners, as at 77B and 77C, FIG. 21, that, as at 77C closely fit said seal layer 77 to the straight flat sides of said rollers 73 and with movable V-slit 77B allowing said rollers 73 to have small twisting motions about its vertical axis with room thereof provided in roller box 74. The two movable said roller keeper seal flaps 77A curl outward against sides of each roller's rolling surface which said flaps 77A follow said rollers movements and keep significant amounts of dirt and grit from entering into the body of said horseshoe. All roller boxes 74 are preferably made of the internally lubricated material ACETRON NS. All rollers 73 are provided with said roller keeper seal flaps 77A that only lightly touch rollers slightly concave roller surface when said rollers are depressed into the horseshoe body and therefor said flaps 77A only provide light frictional resistance to a rolling movement of said roller, therefor said flaps 77A bearing surfaces are expected to have a very long lift. Flaps 77A may as an option, be made of materials that although they may not have an internal lubricating property have smooth low friction surfaces that resist abrasion and have a high tear strength such as Ultrahigh-Molecular-Weight Polyethylene, or the material Millathane or another material having the very desirable properties of being a lightweight non-fatigue material having a high tear strength such as Hytrel of a particular suitable type such as HTX-3177 a thermoplastic elastomer
The concave rolling surface of roller 73 shown in FIG. 21 is exaggerated for sake of illustration. Because the said roller surface is concave the rollers ride bard on their sharply defined end rolling areas that tend to dig into soft ground surface, and have good traction on hard smooth surfaces. Portions of the vertical flat sides of all rollers that project from the horseshoe become buried into soft ground with the said vertical flat surface ends of each railer facing in a different positional arrangement in the horseshoe than of the positions in the horseshoe of all other said rollers and therein provide excellent traction footing for a bone. And when rollers 73 are on smooth hard surfaces 37 rollers of a horseshoe which, as mentioned, are all facing in different directions from each other and bear all of the weight of a horse on the sharp ends of their said concave roiling surfaces ride hard on smooth surfaces and grab onto any minute unevenness and/or rough faults and gritty dirt present on all surfaces to provide excellent footing for a horse. The infinite small amount of lubricant that might be picked up from the physically bound internally lubricated material of a roller box 74 and roller keeper seal flaps 77A onto the bearing surface of a roller is so snail that it posses no lubricant property transferable to a smooth footing surface from the horseshoe rollers surface, in that all but a microscopic amount of lubricant might come onto said rollers from said physically bound lubricated material of said roller box 74 or said flaps 77A because such internally lubricated material is designed to lubricate itself m a manner that reduces the coefficient of friction of the said internally lubricated parts surface for another part to ride on and bear against without passing a significant amount of lubricant to said other part's bearing surface; such as for example the non-stick surfaces of Teflon coated food pans and pots having such a low coefficient of friction foods will not adhere or stick to the said Teflon surface and the said Teflon lubricated surface does not come off of the said pans and pots onto the food; and of which said Teflon material some maintenance free internally lubricated parts such as machine bearings are made of and Teflon is the non transferable physically bound internal lubricant which in fact is a preferable choice for a solid lubricant that is available for the internally lubricated material called Acetron NS of which said roller boxes 74 are to be preferably made of. And Teflon or Graphite are optional choices as the bound internal lubricants in the self lubricating material PTFE which may be the material of choice for the horseshoe's seal layer 77 and its integral roller keeper seal flaps 77A.
When the main bearing surfaces of a roller 73 and/or roller box 74 and perhaps also roller keeper seal flaps 77A become worn and require replacement they are all easily expeditiously removed and then replaced hi and on the main body 86 of the horseshoe. First, if the said flaps 77A also require replacement Said flaps as mentioned, are an integral part of the one piece of flexible material layer 77 which covers most of the bottom surface of the horseshoe's main body 36 as does the bottom plate 94, cover most of the bottom surface of flexible material layer 77, both of which are removed by first backing out but not removing all bottom plate screws 14. All said screws 14 are screwed through keyhole type screw holes in bottom plate with one side of said keyholes larger than the heads of screws 14 therefor by simply having bottom plate 94 turned face downward and tapped to cause said plate 94 to gravitate downward against screw heads of screws 14 and said plate 94 then moved to one side to large hole side of said screw keyholes and said plate 94 then removed from horseshoe past heads of said screws 14. Then said flexible layer 77 is simply removed by peeling it off of said screw heads. All assemblies of a horseshoe roller?) roller box 74 and roller box spring 75 of the horseshoe main body 86 are now made accessible to be lifted out or dumped out of the horseshoe. If the horseshoe is still attached to the hoof of a horse a small sheet of five eights inch thick plywood can be placed under the horses hoof before disassembly of said horseshoe, and with said horseshoe disassembled with bottom coverings off with a hoof held up the said hoof is then allowed to drop onto said plywood to dump all movable parts from the main body 86 of the horseshoe onto said plywood sheet and inspected, which parts are the roller 73. roller box 74 and conical spring 75. Said spring's smallest bottom helical loop is either screwed or forced fitted into recessed spring hole 92 of roller box overhead 80 for attachment to said roller box 74 for expedient removal with removal of said roller box. And for simple and expedient replacement of all hard said movable parts of horseshoe main body 86 still attached to the hoof of a horse may be used having the same perimeter profile as the profile of the horseshoe with openings through the said jig of a form complemental in shape, size and spacing orientation of the horseshoe main bodies 86 roller box compartments 87 positional arrangements, as at 87 FIG. 22. A flat thin slide sheet of rigid material is included placed in a horizontal saw cut, cut through all said roller box compartment 87 jig openings for roller box 74 which said placement of flat thin slide sheet temporarily blocks the bottom open regions of all said jig roller box compartment 87 shaped holes. Then new assemblies of a roller box 74 with attached spring 75 and roller 73 are placed into each said jig openings and rest on said jig slide sheet Said jig has four attached downward projecting pegs employed to properly guide the position of said jigs horseshoe shaped perimeter to complementally match the perimeter form of the horseshoe's main body 86 which positions said jig roller box assembly blocked openings to be exactly aligned to the roller box compartments openings of the horseshoe's main body 86. With said jig placed onto the main body 36 of a horseshoe attached to the uplifted hoof of a horse the said jig slide is then carefully removed from the jig allowing all said jig hole assemblies of roller box 74 and its attached spring 75 and roller 73 to gravitate down together into all of the horseshoe's main body roller box compartments 87. Then either a new or the old flexible seal layer 77 is now installed onto the horseshoe by correctly pushing flexible layer's screw 14 holes onto and snap-fit around all projecting screw heads of screws 14 in horseshoe's main body 86 which will position the roller keeper seal flaps all in place Stops of rollers 73 Next said thin bottom plate 94, the last layer of the horseshoe which protects and keeps in place said flexible seal layer 77 and all flaps ha, is reassembled to the horseshoe in reverse order of its disassembly therefrom with all of the small screws 89 now projecting out of said metal plate the sides of said metal plate 94 and side of flexible layer 77 are aligned to and protected at the inside projecting surface of perimeter lip 107 of said horseshoe main body 87, and then said screws 14 are all firmly screwed down in place onto said metal plate and thus said horseshoe is filly assembled and refurbished and ready to be of service to the horse as disclosed in the specification.
The said assembly of the horseshoe of this invention is approximately of the—manner of which the manual assembly of new horseshoe units may be conducted.
The said horseshoe may be supplied requiring assembly as disclosed above, or may come already almost completely assembled as illustrated at left side of drawing FIG. 22 with all small screws 14 extended outwards through holes in layer 77 in ready positions for shodding the unit to the hoof of a horse accept for units bottom plate 94 which would be packed as a separate part with a horseshoe unit, but all small screws 89 backed outwards into ready positions for installation of said bottom plate 94. The flexible layer 71 may be furnished as mentioned with holes in it somewhat larger than screw heads 90 to allow withdrawing partially assembled screws 91 through said flexible layer 77 for shodding the horseshoe to a horses hoof without removal of said layer 77 as disclosed above. Small screws 14 which remain partially screwed into the horseshoe main body 86 keep said layer 77 sufficiently enough in place to retain all parts shown within said main body 86 therefore simplifying shoeing of the horseshoe to the hoof of a horse also as disclosed above.
The horseshoe of this invention may be installed onto a horse in any manner deemed practical such as aching to conventional horseshoes already shod to a horse temporarily or reconsidered as permanent installations. Said horseshoe of this invention may be attached to a horse via straps, or glued onto a hoof or attached to a horses boots and even ached to a hoof as a horseshoe of this said invention in more than one piece such as one separate piece for each side of a hoof which would be another means to allow natural flexing of the hoof wall when the horse is in motion; or complemental horseshoe fork end pieces of the flexible frog regions of a hoof separate from a contiguous third piece of said horseshoe that is attached to the forward sides and toe of said hoof or by any means of attachment that makes use of the inventiveness of the horseshoe's features including safety, agility and refurbished long life features of the horseshoe being within the scope of the invention.
