manifested in the preferred embodiment , the present invention provides a relatively safer and more easily worn stilt than has heretofore been available . this is achieved through the positioning of a leg brace at the rear of the stilt . a preferred embodiment articulating stilt 10 incorporating a rear brace 80 is illustrated in fig1 . articulating stilt 10 most preferably incorporates the articulation as illustrated by emmert and incorporated herein above by reference . stilt 10 has a foot 70 operative to contact a surface to be traversed , which would ordinarily be the ground , a floor or other surface . while not essential to the present invention , a heal pad or surface 72 may be provided , and a toe pad 74 . a boot rest 50 is designed to support a human foot , boot , foot covering or the like thereon . boot rest 50 will preferably include bindings 40 , 60 to securely hold a foot , boot , foot covering or the like in secure position relative to boot rest 50 . more detailed description of bindings 40 , 60 and the balance of boot rest 50 may be found in my co - pending patent application ser . no . 11 / 613 , 115 filed dec . 19 , 2006 , the entire contents which are incorporated herein by reference . at least two risers 20 , 30 extend between foot 70 and boot rest 50 . riser 20 is coupled through a pivot 22 to boot rest 50 , and through pivot 24 to foot 70 . similarly , riser 30 is coupled through a pivot 32 to boot rest 50 , and through pivot 34 to foot 70 . these pivots provide the important articulation which permits natural balance and movement . as may be recognized from the illustration in fig1 , this combination of risers 20 , 30 , with boot rest 50 and foot 70 form a quadrilateral linkage which in the preferred embodiment is also a parallelogram . risers 20 and 30 in the preferred embodiment are adjustable in length , by passing pins , bolts , or other suitable fasteners 26 , 36 through one of an assortment of holes in lower riser members 28 , 38 . most preferably , such a plurality of holes will be generally vertically displaced from each other . the length of these risers 20 , 30 in turn determines the elevation provided by stilts 10 . in typical construction applications this may only be one or a few feet , though in other applications very different riser lengths may be appropriate . while not essential to the invention , a centering spring arrangement is provided which comprises a pair of brackets 33 , 39 anchored to riser 30 , and having a pair of springs 35 , 37 extending therebetween . at the juncture between springs 35 , 37 is a bracket 25 , which is anchored to riser 20 . a rod may be provided which passes through the center of springs 35 , 37 , ensuring that the springs are captured and not able to be dislodged from proper position . in operation , when stilt 10 is tilted forward or backward , bracket 25 will move relative to brackets 33 , 39 , alternatively compressing one or the other of springs 35 , 37 . when no force at all is applied , such as when stilt 10 is lifted from the ground , springs 35 , 37 in cooperation with bracket 25 will ensure that stilt 10 returns to a neutral position as illustrated in fig1 . an upper leg strap 84 and a rear brace 80 coupling boot rest 50 to upper leg strap 84 are also provided . rear brace 80 extends from riser 30 through a gentle arc or curve upwards to the rear side of the leg of a wearer . in the preferred embodiment rear brace 30 is in a plane parallel to the paper which is also co - planar with risers 20 , 30 . this alignment ensures that no rotational torque will be generated during striding or walking movement . preferably , upper leg strap 84 is adjustably coupled with rear brace 80 adjacent to upper termination 82 , such that upper leg strap 84 may be raised or lowered along rear brace 80 to accommodate different wearers &# 39 ; preferences . such adjustment may be made through any suitable means , including but not limited to a plurality of fastener holes in rear brace 80 within which a complimentary fastener may pass to couple upper leg strap 84 to rear brace 80 . it is highly preferred that riser 30 and pivot 32 align as closely as possible with upper leg strap 84 . this preference is due to the desire to limit any distance change between the point where upper leg strap 84 couples to a wearer and boot rest 50 . said another way , if a person were to pivot their ankle to lower their toes , their foot between toes and heel lowers . if pivot 32 is in line with boot rest 50 , then there is no distance change required between upper leg strap 84 and boot rest 50 . consequently , a user may securely strap upper leg strap 84 , and not experience any relative motion . for purposes of contrast with the present invention , if pivot 32 were offset to the right in fig1 and therefore adjacent to heel cup 45 , then the person &# 39 ; s foot would need to lower above riser 30 . such motion would require movement between the wearer &# 39 ; s leg and upper leg strap 84 , which is not possible if upper leg strap 84 is securely fastened . in the preferred embodiment , rear brace 80 is coupled directly to riser 30 adjacent to rear brace termination 81 . this coupling in the preferred embodiment is a rigid , welded connection , though other suitable coupling may be used . additional strength may be gained by providing a securing member 83 . in one conceived alternative embodiment , the coupling between rear brace 80 and riser 30 is pivotal . in this alternative embodiment , securing member 83 is extensible , through any suitable means including but not limited to the fastener and hole arrangement similar to that used on each riser 20 , 30 , to vary the angular relationship between riser 30 and rear brace termination 81 . this varied angular relationship permits rear brace 80 to be tilted farther rearward or forward , to further accommodate a user &# 39 ; s preference . it will be appreciated from the foregoing description that coupling rear brace 80 directly and rigidly to boot rest 50 is not desirable , since when the wearer tilts their foot , they do not want upper leg brace 84 to move . however , it is contemplated herein that rear brace termination 81 may alternatively be coupled , for exemplary purposes , to pivot 32 . in yet a further alternative , a separate pivotal coupling may be provided to couple rear brace 80 directly to boot rest 50 . preferably , upper leg strap 84 will most preferably include sufficient padding to adequately distribute forces across a larger surface area than in the prior art without constricting circulation within the leg . an added benefit to the use of quick - release ratcheting straps as illustrated herein arises from the facility and speed by which the preferred embodiment may be attached and detached . with only a few quick movements , the user may step into and tighten the preferred embodiment , and with even fewer and simpler quick movements , the user may disengage and release the preferred embodiment . with padding appropriate to the particular strap , these preferred quick - release ratcheting straps will also vastly improve the comfort of the stilts , accompanied by a reduced amount of fatigue . not only do the straps reduce fatigue , but the rear brace likewise generates less fatigue . this is because , without undesirable torque , the user does not have to use unusual muscles to keep their feet properly aligned as they walk about . in turn , reduced fatigue means that the stilts of the preferred embodiment may be worn for long periods of time to meet the requirements of certain applications . this not only improves work efficiency , but it is also known that fatigue is a common cause of many mishaps . it follows then that reducing the amount of fatigue , so long as a worker still stops at or near the same time , will also reduce the likelihood for mishaps or injuries . heel binding 45 includes an arched heel cup which defines a rear limit to movement of a human foot , shoe or boot upon boot rest 50 as disclosed in my co - pending patent application ser . no . 11 / 613 , 115 incorporated herein above by reference . as is visible in fig1 , this arched heel cup rises above boot rest 50 substantially , which permits the lower heel portion of a foot covering or foot to be captured between the arched heel cup and boot rest 50 . the geometry of the arched heel cup may be customized , where desired to conform to one or more particular types of foot coverings , to best engage therewith . for exemplary purposes only , and not limited thereto , some boots have a pronounced achilles tendon region which is recessed relative to the sole adjacent to the heel . in such instance , the arched heel cup may be shaped to define an arch which matches the geometry of the particular shoe , or of shoes or boots of more broad types or geometries . as may be apparent , the angle of binding 40 leads to the drawing of a human foot or foot covering against boot rest 50 and the heel cup when binding 40 is tightened , for securement therewith . this ensures that the user &# 39 ; s foot will remain properly aligned with riser 30 , pivot 32 and upper leg strap 84 . the present invention , as manifested by the present preferred embodiment , provides a stilt which affords correct bio - mechanical movement . this is because the user may extend the stilt in front of their leg , as with a normal walking motion . in the prior art , using the known heel cups and straps , the wearer &# 39 ; s heel would be prone to slipping or total release from the heel cup . this would , in turn , lead to a spill and possible injury , since the stilt would fail to stay properly aligned and coupled to the person &# 39 ; s leg . in contrast , in the present invention such motions are desirable . with the preferred articulating stilt , as described and taught herein , even the articulation within the ankle joint is preserved . no torque is generated by ordinary striding or walking . consequently , bio - mechanical movements which mimic ordinary movements are preserved . from the foregoing descriptions , it should now be apparent that the materials used for the production of the present invention and embodiments thereof is not critical , so long as the materials do not interfere with the functions and operations that have been outlined herein above . as but one example , the preferred embodiment may be fabricated from metals suitable for the intended work environment . however , a number of plastics and composites are known which would provide suitable performance . consequently , one of ordinary skill in the art , with the knowledge of the present disclosure , will choose materials suitable for a given application in consideration of an intended ultimate cost of fabrication . while the foregoing details what is felt to be the preferred embodiment of the invention , no material limitations to the scope of the claimed invention are intended . further , features and design alternatives that would be obvious to one of ordinary skill in the art are considered to be incorporated herein . the scope of the invention is set forth and particularly described in the claims herein below .
the present invention combines an articulated stilt with a rear - mounted leg support or brace behind the leg of the user . the articulating stilt has a foot operative to contact a surface to be traversed , a boot rest operative to support a human foot thereon extending in a longitudinal direction between a heel region and toe region and thereby defining a longitudinal axis , and at least two risers extending between the foot and boot rest coupled thereto through pivotal joints . the rear leg brace has an upper leg binding , and an extension coupling the upper leg binding to articulating stilt . according to further manifestations , the rear leg brace may be fixed or pivotal relative to the risers , and when pivotal , may be adjusted to user preferred angular orientations . the use of a rear - mounted brace eliminates undesirable torque during movement , enabling a more anatomically and bio - mechanically correct movement . this bio - mechanically correct movement results in less stress on muscles and joints and in turn allows a user to work more comfortably for extended periods of time .
